This study reports a post-market clinical follow-up (PMCF) evaluation of a clinical decision support system (CDSS), integrated into routine care within Portugal’s largest private healthcare network (CUF) to determine whether it can deliver appropriate urgency advice and clinically useful reports, and whether its use is associated with improved preparedness and consultation efficiency in real-world practice. Methods: This was a prospective, observational study. Adults aged ≥ 18 years completed a full symptom assessment via the myCUF application before consultation. Participants provided informed consent and completed a post-assessment survey; treating physicians completed structured post-consultation surveys. Primary endpoints were the appropriateness of urgency advice and of the assessment report, including the reasonableness of suggested conditions, completeness of symptom history, concordance of the main problem with the consultation focus, and inclusion of the physician’s final diagnosis. Secondary endpoints included consultation efficiency and time saving, clinician preparedness, confidence in diagnosis, and perceived usefulness of the assessment report information. Analyses used descriptive statistics, confidence intervals, risk differences and risk ratios, with subgroup comparisons by specialty, sex, and age. Results: A total of 1,470 participants completed the post-assessment survey. Physicians returned 163 consultation surveys, of which 60 were based on reports reviewed before the encounter and formed the basis for efficiency and preparedness analyses. Urgency advice was judged appropriate in most cases (top advice level: 74.1%, 120/161; 95% CI 67.4–80.1; all advice levels: 77.6%, 125/161; 95% CI 70.1–83.9), with no significant differences by specialty, sex, or age. In cases where advice was not considered appropriate (8.7%; 95% CI 5.0–13.9), all disagreements reflected conservative, over-cautious advice; no instances of under-triage were identified. Report appropriateness was high: conditions provided as suggestions were judged reasonable in 73.0% (119/163; 95% CI 65.7–79.5), the symptom list was considered complete in 78.4% (127/162; 95% CI 71.2–84.4), the main problem discussed in the consultation matched the information in the report in 82.8% (135/163; 95% CI 76.1–88.2), and the clinician’s most likely diagnosis was included among the suggested conditions in 80.4% (131/163; 95% CI 73.5–86.0). Physicians reported efficiency improvements in 66.7% (40/60; 95% CI 53.3–78.3) and time savings in 66.1% (39/59; 95% CI 52.3–77.6), most often during the consultation itself. Increased preparedness for the consultation was reported in 71.7% (43/60; 95% CI 58.6–82.5) and was strongly associated with the perceived usefulness of the condition suggestions. Among participants, 80.5% (1,183/1,470; 95% CI 78.4–82.5) reported that all symptoms were captured in the assessment report, 71.2% (1,046/1,470; 95% CI 68.7–73.6) felt more prepared for the consultation, and 33.0% (485/1,470; 95% CI 30.5–35.6) reported reduced anxiety after assessment completion. Completeness and preparedness were associated with lower anxiety. Conclusion: In routine practice, an integrated symptom assessment device provided appropriate urgency advice and clinically useful reports, and was associated with greater clinician preparedness, perceived efficiency improvements, and positive patient experience. These PMCF findings support continued safe use as a digital front door and contribute real-world evidence for ongoing conformity assessment of Ada, a clinical decision support system and a Class IIa medical device under EU MDR 2017/745. Health sciences/Diseases Health sciences/Health care Health sciences/Medical research digital front door symptom assessment self-triage urgency advice clinical workflow consultation efficiency clinician preparedness patient experience post-market clinical follow-up Figures Figure 1 Introduction Health systems face mounting pressure from population ageing, multimorbidity, and persistent workforce shortages. These trends increase demand while restricting the supply of clinical time, lengthening queues, and threatening timely access to appropriate care. Delayed or misdirected access has been associated with poorer outcomes, including avoidable hospitalisations and excess mortality, underscoring the need for scalable approaches that preserve both quality and safety. 1 , 2 Efforts to address these pressures can be grouped across three phases of the care pathway. Before the visit, patients require support to determine whether care is needed, where to seek it, and how urgently; in some cases, empowering them with reliable information may enable safe self-management. During the visit, clinicians benefit from tools that improve efficiency and quality of the encounter. High documentation burden remains a persistent challenge: in acute care, overcrowding, often driven by non-urgent presentations, forces clinicians to take and record histories under time pressure, with frequent interruptions that increase the risk of omissions. 3 Documentation quality varies with experience: junior physicians may take three times longer to complete histories, while senior physicians are faster but sometimes less complete. 4 Overstretching under these conditions is linked to higher error rates. 5 Structured, interactive, and pre-populated records have therefore been proposed as part of the solution, with digital history-taking tools offering the potential to improve clarity, accuracy, and completeness while reducing burden. 6 After the visit, technologies for monitoring and asynchronous communication can reduce unnecessary attendances, support adherence, and promote continuity. The shared goal across phases is to optimise use of healthcare resources, enhance the experience of both patients and professionals, and improve outcomes. Technology is increasingly being explored as a lever across these phases. AI-based scribe tools aim to reduce documentation burden and free time for patient interaction. Machine learning has been applied to clinical decision support and error reduction. 7 Large language models are being evaluated for summarisation, triage, and diagnostic support, though careful integration is required to ensure reliability. 8 A particular class of tools with relevance at the entry point to care are the so-called digital front doors (DFD). These patient-facing, digitally enabled platforms combine symptom assessment, self-triage, booking, and sometimes remote consultations to guide people to the right service at the right time. 9 , 10 While conceptually spanning all three phases, most implementations focus on the pre-visit stage and preparation for the consultation. The evidence on DFDs based on CDSS remains mixed. Systematic reviews report wide variation in diagnostic accuracy and appropriateness of urgency advice, with performance influenced by presentation type and evaluation method. 11 , 12 Much of the literature is based on vignette studies or specialty-specific pilots, limiting generalisability. Real-world evaluations across broader patient populations and specialties remain scarce. Against this backdrop, the ESSENCE (E-health Self Symptom assEssmeNt as a front door and facilitator of CarE) post-market clinical follow-up study evaluates a regulated symptom assessment device integrated into routine practice in Portugal. In contrast to our companion analysis focusing on health-seeking behaviour, this paper examines the appropriateness of the information provided and its impact on consultation quality and effectiveness, asking whether the tool supports safe and appropriate guidance, strengthens decision-making and care navigation, and enables more prepared and efficient consultations. Objectives To determine whether a CDSS integrated as DFD can deliver appropriate urgency advice and clinically useful reports, and whether it is associated with improved preparedness and consultation efficiency in real-world practice. Methods Study Design and Setting This paper reports results from ESSENCE, a prospective quality-improvement evaluation of a digital clinical decision support system developed by Ada Health (Berlin, Germany) and implemented in Portugal’s largest private healthcare network (CUF), integrated through the myCUF application. ‘Ada Assess’ (commonly known as ‘Ada’), manufactured by Ada Health GmbH (Berlin, Germany), is a CE-marked Class IIa medical device under the EU MDR 2017/745. Adults (≥ 18 years) using the myCUF app to complete a full assessment for themselves were eligible. Inclusion required completion of pre- and post-assessment questions, informed consent, and report sharing with a healthcare provider. Participants were instructed not to use the CDSS in emergency situations as per device intended purpose as described in the instructions for use and disclaimers. Enrolment ran from November 2023 to October 2024. Data Collection Procedures The full ESSENCE protocol has been reported previously. 13 In brief, participants responded to an intended question about their planned healthcare-seeking behaviour before completing the self-assessment through the CDSS. The assessment generated a structured report including suggested conditions based on user provided information, a summary of entered symptoms, and urgency advice. Each suggested condition was paired with a condition-specific urgency recommendation, expressed using eight-point scale (Self-care, Self-care with pharmacy support, Primary care in 2–3 weeks, Primary care in 2–3 days, Primary care on the same day, Primary care within 4 hours, Emergency care, and Call ambulance). Physicians were asked to rate the appropriateness of urgency advice at two levels: (i) whether, based on the patient’s symptoms, the recommended advice for the most likely (top suggested) condition was reasonable, and (ii) whether the urgency advice levels across all suggested conditions were reasonable. In addition, the system generated an overall advice level (highest acuity across all advice suggestions), which was linked to the CUF care navigation options (Call Ambulance, Emergency Care, Video call with a General Practitioner). This overall advice level represented the guidance presented to the patient as the appropriate next step in care. Immediately after the assessment, participants completed a survey, which captured completeness of symptom entry, preparedness for the upcoming consultation, and perceived psychological effects (e.g. anxiety). Following the consultation, treating physicians were instructed to complete a structured survey immediately after seeing the patient, or at the latest by the end of the same working day. Where this was not possible, surveys were completed retrospectively using the patient record. In these retrospective cases, only a reduced set of items was addressed, focusing on the appropriateness of the report information (e.g. urgency advice, reasonableness of suggested conditions, completeness of the symptom list, and concordance of the report with the consultation focus and final diagnosis), whereas questions relating to the effect of the report on the consultation process itself were excluded. Physicians also reported whether the report prompted additional diagnostic tests or flagged critical findings. Further items evaluated consultation efficiency, time savings in specific activities, and perceptions of patient engagement and being informed. Participant and physician surveys combined Likert-type scales, categorical response options, and free-text fields. Full survey instruments are available in Appendix 2. Data Analysis The ESSENCE study had two predefined primary endpoints: (i) the appropriateness of the urgency advice, assessed through two survey items in which physicians rated whether the advice for the most probable condition and overall advice levels were reasonable; and (ii) the appropriateness of the assessment report, evaluated across multiple dimensions including the reasonableness of suggested conditions, completeness of the symptom list, concordance of the main problem with the consultation focus, inclusion of the physician’s most likely diagnosis among the suggested conditions, and whether the report provided useful information, prompted additional tests, or identified critical findings. Survey responses were captured on a five-point Likert scale from Strongly disagree to Strongly agree and dichotomised for analysis, with Agree and Strongly agree considered appropriate. Relationships between survey measures such as completeness, reasonableness, and perceived usefulness and physician-reported outcomes (efficiency, preparedness, perceived patient effects) were examined descriptively or, where appropriate, using the tests described above. For participant-reported outcomes, associations between completeness, preparedness, and anxiety reduction were evaluated similarly. Missing data were handled by excluding cases on a per-item basis. Continuous variables were summarised as means with standard deviations or as medians with interquartile ranges, depending on distribution, and categorical variables were described using frequencies and percentages. Comparisons across subgroups (specialty, sex, and age group) were performed using Pearson’s χ² test or Fisher’s exact test, as appropriate, with a two-sided significance level of 0.05. For specialty-level analyses, specialties with fewer than ten consultations were grouped under Other to enable meaningful comparison. Ninety-five per cent confidence intervals for proportions were calculated using standard binomial methods. Confidence intervals for risk differences and risk ratios were reported where relevant. All analyses were conducted in Python (v3.10). Data Management and Ethics Data was securely stored in a validated electronic system (Teamscope) using unique identifiers. Ethical approval was granted by the Comissão de Ética para a Investigação Clínica (No. 2204JJ351 and No. 2309JJ660 ). The study was registered at ClinicalTrials.gov ( NCT06846957 ) - registry date: February, 26th, 2025, and complied with the Declaration of Helsinki and ISO 14155:2020 guidelines. STROBE guidelines were followed throughout. Results Study Population A total of 1,470 participants were enrolled, with a mean age of 38.5 years (SD 12.5, range 18–83), of whom 57.7% (848/1,470) were female. Participants initially entered a median of two symptoms (IQR 1–3). Cases were grouped by clinical specialty according to their presentation. Participants completed a post-assessment survey, which provided information on the completeness of symptom entry, preparedness for consultation, and psychological effects of the assessment. Physician surveys were completed for 163 consultations, in different settings: 13 in-person visits in the emergency department and 150 teleconsultations. Of the total, 103 surveys were completed retrospectively, where the physician had not reviewed the report before the consultation, and 60 were completed immediately after consultations in which the report was reviewed in advance. The latter group (n = 60) formed the basis for analyses of consultation efficiency and preparedness. The participant inclusion process is outlined in a STROBE flow diagram (Fig. 1 ). Reasonability of urgency advice Physicians agreed that the urgency advice level associated with the most probable condition was reasonable in 74.1% of cases (120/161; 95% CI 67.4–80.1). No differences were observed by case specialty (p = 0.535), sex (p = 0.237) or age group (p = 1.000) (Table 1 , Appendix Table 1A and 1C). For each case, physicians were asked whether all urgency advice levels provided by the assessment report, i.e. condition-specific urgency recommendations, were reasonable; in 77.6% (125/161; 95% CI 70.1–83.9) of cases the recommendations were considered reasonable. No significant differences were found with case specialty (p = 0.107), sex (p = 0.710), or age group (p = 0.685) (Table 1 , Appendix Tables 1B and 1C).

Table 2 summarises these results. Physicians rated the overall urgency advice as appropriate in 77.6% (95% CI 70.1–83.9), neutral in 13.7% (95% CI 8.5–20.2), and not appropriate in 8.7% (95% CI 5.0–13.9) (14/161). To understand whether advice judged not appropriate nonetheless resulted in safe user behaviour, the 14 cases in which the CDSS advice was rated not appropriate were examined and compared participants’ actual care-seeking actions. In five of these cases (35.7%; 95% CI 12.8–64.9), participants’ actions matched what physicians considered appropriate, indicating that some users sought care consistent with clinical expectations even when the CDSS advice was inaccurate (Table 2 ). Table 2 Appropriateness of care recommendation with actual participant behaviour comparison. Cases were grouped by the highest-acuity recommendation (overall advice level) generated by the CDSS. Values show physician ratings of appropriateness (appropriate, neutral, not appropriate) and, for cases judged not appropriate, the patient’s actual care-seeking behaviour and whether that behaviour was considered appropriate.

To further characterise the nature of the inappropriate advice, within the same 14 cases, the CDSS’s highest (overall) advice level was compared with the physician’s recommended care-seeking behaviour. Physician responses for what the appropriate behaviour in 3 levels (“Managing symptoms at home or consulting a pharmacist”, “Consulting a GP” or “Consulting a specialist” and “Emergency Room / Emergency”) and were mapped onto the same eight-level CDSS advice scale (Appendix Table 2A). The CDSS recommendation coincided with the physician’s behaviour recommendation in nine cases (64.3%; 95% CI 35.1–87.2) and was more cautious in five (35.7%; 95% CI 12.8–64.9). Importantly, no instances were identified in which the CDSS provided a less urgent recommendation than physicians considered appropriate, indicating that all discrepancies reflected conservative rather than unsafe guidance. It should be noted that physicians’ recommended behaviours were captured using a simplified three-level categorisation (self-care, primary care, or emergency care), whereas the CDSS generated advice across an eight-level scale. Consequently, apparent agreements may partly reflect differences in scale granularity rather than true clinical agreement. Appropriateness of the assessment report Appropriateness of the assessment report was evaluated across multiple dimensions, including the reasonableness of suggested conditions, completeness of the symptom list, concordance of the main problem with the consultation focus, inclusion of the physician’s most probable diagnosis, provision of additional useful information, and whether the report prompted further tests or flagged critical findings (Table 3 ).

The symptom list was considered complete in 78.4% (127/162; 95% CI 71.2–84.4), and the main medical problem matched the consultation focus in 82.8% (135/163; 95% CI 76.1–88.2). Additional useful patient information was reported in 69.9% (107/153; 95% CI 62.1–77.0), the report prompted further diagnostic tests in 19.5% (31/159; 95% CI 13.8–26.5), and critical findings were flagged in 33.1% (52/157; 95% CI 26.0–41.0). The physician’s most probable diagnosis was included among the suggested conditions in 80.4% (131/163; 95% CI 73.5–86.0), with significant differences by specialty (p = 0.035), but no significant variation by sex (p = 1.000) or age group (p = 0.191) (Appendix Table 3A). Across most specialties, results were close to or above 80%, indicating generally strong correspondence between the CDSS suggestions and physicians’ clinical reasoning. Physicians were more likely to find the diagnosis included in the report when the consultation focused on the same symptoms or medical problem as those stated in the assessment: most probable diagnosis included in 87.4% (118/135; 95% CI 80.7–92.6) of such cases, compared with 46.4% (13/28; 95% CI 27.5–66.1) when the consultation addressed a different problem (p < 0.00001). This indicates that discrepancies in most likely diagnosis often arose when patients presented a different medical problem in the consultation than the one they had reported during the assessment. Consultation efficiency and time The mean consultation length, based on 59 valid responses, was 13.0 minutes (SD 5.4; median 14; range 4–28). Time savings during the consultation were reported in 66.1% (39/59; 95% CI 52.3–77.6), while 33.9% reported no time saved (20/59; 95% CI 22.4–47.7). Time was most often saved during the consultation itself (29/39; 74.4%; 95% CI 59.7–84.7). Time saving was significantly (p = 0.033) more often observed in clinical cases judged as easy (11/15; 73.3%; 95% CI 44.9–92.2) compared with moderate or difficult ones (10/26; 38.5%; 95% CI 20.2–59.4). Physicians rated the usefulness of the condition suggestions for the consultation work favourably. Across 60 valid responses, 46.7% (28/60; 95% CI 33.7–60.0) judged the report to be very useful, 38.3% (23/60; 95% CI 26.1–51.6) as somewhat useful, and 15.0% (9/60; 95% CI 7.1–26.6) as not useful. Efficiency improvement was reported by 66.7% (40/60; 95% CI 53.3–78.3) (Table 3 ). Efficiency improvements were more frequent when all suggested conditions were judged reasonable (72.3%, 34/47; 95% CI 57.4–84.4), compared with 60.0% (6/10; 95% CI 26.2–87.8) when only some were reasonable and 0.0% (0/3; 95% CI 0–70.8) when none were reasonable, although this trend did not reach statistical significance (p = 0.066). In contrast, perceived usefulness of the condition suggestions was a strong predictor of efficiency: improvements were reported in all cases rated very useful (100%, 28/28; 95% CI 87.9–100), compared with 52.2% (12/23; 95% CI 30.6–73.2) when somewhat useful and 0.0% (0/9; 95% CI 0–33.6) when not useful (p < 0.0001) (Appendix Table 4A). Preparedness for the consultation was reported by 71.7% (43/60; 95% CI 58.6–82.5). This outcome was significantly associated with perceived usefulness of the suggested conditions (p < 0.0002) but not with their reasonableness (p = 0.56) (Appendix Table 4B). Participant survey findings In the post-assessment participant survey, across the three participant-reported endpoints (symptom capture in report, preparedness for consultation, and reduction of anxiety), a joint analysis was possible for those with non-missing answers, i.e. participants without skipped questions to all three items (1,383/1,470). In this cohort, 95.7% (95% CI 94.6–96.6) of participants reported at least one positive effect (22.2% [95% CI 19.9–24.7] in one domain, 41.1% [95% CI 38.4–43.8] in two, and 32.3% [95% CI 29.8–35.0] in all three), while 4.3% (95% CI 3.4–5.4) reported no positive effect on any endpoint. Overall, 80.5% (1,183/1,470; 95% CI 78.4–82.5) reported that all symptoms they wished to include were captured in the assessment, and 71.2% (1,046/1,470; 95% CI 68.7–73.6) felt prepared for their consultation (Appendix Table 5A). Preparedness was more common among those who reported all their symptoms (80.4% vs 65.7%; risk difference + 14.7 pp, 95% CI 7.4–21.9; RR 1.22, 95% CI 1.10–1.36) (Appendix Table 5B). One-third of participants (33.0%, 485/1,470; 95% CI 30.5–35.6) reported feeling less anxious about their health after using the CDSS, while 30.9% (95% CI 28.4–33.4) reported not feeling less anxious and 29.0% (95% CI 26.6–31.5) reported no difference. No significant differences in anxiety reduction were observed by sex or age group (p = 0.49 and p = 0.46, respectively). Reporting all symptoms was associated with a higher likelihood of feeling less anxious after using the CDSS (37.8% vs 21.6%; risk difference + 16.2 pp, 95% CI 9.7–22.7; RR 1.75, 95% CI 1.32–2.32). Similarly, those who felt prepared for the consultation after completing an assessment felt less anxious (43.9% vs 8.0%; risk difference + 35.9 pp, 95% CI 31.6–40.3; RR 5.51, 95% CI 3.70–8.21) (Appendix Table 5B). Changes in intended care were related to changes in anxiety. Reduced anxiety was most common among those who de-escalated intended care (48.1%, 95% CI 43.2–53.0) and those who escalated care (44.0%, 95% CI 38.7–49.5), compared with 33.1% (95% CI 29.5–36.8) in the no-change group. Participants in the made-certain group reported reduced anxiety in 38.7% (95% CI 30.8–47.1) of cases, while those in the made-uncertain and stayed-uncertain groups reported lower rates (24.3% [95% CI 17.1–33.1] and 26.7% [95% CI 17.3–38.8], respectively). Overall differences between groups were not statistically significant (p = 0.141). Discussion This study evaluated a regulated digital clinical decision support system integrated into Portugal’s largest private healthcare network. In real-world use, the CDSS produced clinically appropriate reports, supported consultations, and was associated with positive patient experiences. Physicians rated the urgency advice as appropriate in the great majority of cases, indicating that the system effectively guided patients to a suitable level of care and performed safely within its intended purpose. Diagnostic agreement was also high, with physicians’ most probable diagnoses commonly included among the system’s suggested conditions, confirming the clinical validity of the differential lists and their relevance to real patient presentations. The only clear exception was dermatology, where inclusion was considerably lower, a finding consistent with the fact that dermatological diagnosis depends largely on visual pattern recognition rather than symptom description. This difference highlights both the strengths and inherent limitations of a text-based DDSS, which performs best when diagnostic reasoning is driven by the patient’s reported history rather than visual assessment. Both physicians and patients reported feeling better prepared for the consultation, reflecting the system’s value in improving the structure and completeness of information at the point of care. These findings indicate that a CDSS can generate actionable information, combining appropriate care-level advice with plausible diagnostic hypotheses, while also structuring the underlying symptom and history information in ways that promote safer navigation and more efficient doctor–patient interaction. The report produced by the CDSS represents a structured account of the patient’s history, bridging the pre-consultation and consultation phases. Its value lies in capturing the breadth of symptoms, translating them into plausible conditions, and presenting a concise problem summary for clinical review. When the consultation addressed the same problem reported by the patient in the assessment, the physician’s final diagnosis was commonly included among the suggestions. Evidence from computer-assisted history taking and patient-entered questionnaires shows that such structures improve completeness and data quality compared with unstructured note taking. 6 , 14 They can also help clinicians identify relevant but unspoken symptoms, supporting diagnostic reasoning. By providing a ready-made overview, the CDSS effectively front-loads part of the information-gathering task, reducing redundancy during the visit and clarifying what remains to be verified or explored. Clinical consultations follow a predictable but time-pressured sequence: history taking, examination, and synthesis, often interrupted by documentation tasks and parallel digital systems. In this context, structured digital inputs can alleviate cognitive load and documentation burden. 15 , 16 In this study, physicians most often saved time during the encounter itself. Beyond efficiency, the CDSS appeared to strengthen diagnostic confidence. Associations between the perceived usefulness of condition suggestions and both preparedness and efficiency suggest that clinicians approached the consultation with a clearer differential. For junior doctors in particular, structured data capture can compensate for limited experience in eliciting and synthesising patient information; studies show that novice practitioners rely more on analytical and externally guided reasoning, often gathering broader but less synthesized information, while experts depend on pattern recognition and faster intuitive processing. 17 , 18 Structured digital tools, such as electronic templates and decision-support systems, have been shown to improve completeness and confidence among junior primary care clinicians, effectively scaffolding their reasoning and narrowing the experience gap. 19 , 20 Despite these benefits, only a minority of physicians in this study cohort opened and reviewed the report before consultations (60 out of 163), revealing how challenging it is to change established clinical habits. Behavioral barriers such as perceived time cost or lack of integration into the electronic record are common across digital health implementations. Practical levers for improvement include automatic insertion of the report into the electronic medical record, reminders within scheduling software that alert clinicians when a patient has completed a pre-assessment and prompt report review before the consultation, training actions, and peer examples demonstrating efficiency gains. 21 , 22 From the patient perspective, the CDSS improved both preparedness and led one-third of participants to feel less anxious. Participants who felt prepared were more likely to report reduced anxiety, and physicians noted that these patients arrived more engaged and informed. This sequence, from complete self-report to preparedness and lower anxiety, suggests that structured symptom assessment can foster confidence rather than amplify concern. These findings contrast with evidence linking unfiltered internet searches to increased anxiety and cyberchondria 23 , indicating that clinically validated pre-consultation assessment can help counter misinformation by contextualising symptoms and clarifying appropriate next steps. Together, these findings show that CDSS before the clinical encounter can add value across the care pathway: for clinicians, they enhance preparedness, confidence and safety vigilance; for patients, they promote reassurance and engagement. Realising these benefits at scale will require embedding such tools into daily workflows and maintaining systematic feedback loops for post-market learning. The ESSENCE study, integrating real-world evidence and clinician feedback, offers a blueprint for responsible evolution of digital support within healthcare systems. Limitations & Strengths Several limitations should be considered. Participants were adults using the myCUF application within a private healthcare network, likely favouring individuals with higher digital access and health literacy. Certain specialties were represented by small numbers, and older groups may have been under-represented since ≥ 65 year old subgroup comprised few participants. These factors may limit the extent to which the findings reflect all patient groups. In addition, results are drawn from a single, well-resourced private system with specific workflows. Performance and workflow impact may differ in public or resource-constrained settings. Replication in diverse health systems will be important to assess generalisability. Nonetheless, the consistency of results across multiple endpoints supports confidence in the conclusions. The ESSENCE study is one of the first prospective, real-world evaluations of a CE-marked symptom assessment tool integrated into routine care pathways of a major healthcare system. Strengths include the dual perspective of patients and clinicians, enabling robust triangulation of outcomes across appropriateness, efficiency, preparedness, and patient reassurance. Conducted in Portugal’s largest private healthcare network, the study encompassed diverse specialties and care contexts, while predefined endpoints such as urgency advice appropriateness, diagnosis inclusion, and consultation efficiency provide structured evidence of performance. The prospective PMCF design, aligned with ISO 14155:2020, ensures regulatory and methodological rigour, strengthening the reliability and generalisability of the findings for assessing the safety, performance, and benefit of a CDSS in practice. Conclusion The ESSENCE study provides real world evidence that a CDSS can effectively support safe, appropriate, and more confident decision making at the point of entry to care. In routine practice, urgency advice was judged appropriate, the assessment report aligned with clinical reasoning, and physicians reported better preparation for consultations with meaningful efficiency improvements. Participants described feeling prepared and, for a substantial proportion, less anxious after using the CDSS. This paper reports the primary endpoints on appropriateness of urgency advice and of the assessment report, and the secondary endpoints included consultation efficiency and time saving, clinician preparedness, confidence in diagnosis, and perceived usefulness of the assessment report information. Taken together, these findings show that the value of CDSSs in this context lies not only in what it predicts but in how it structures information so that patients and clinicians can act on it with clarity and confidence. In summary, integrating a clinically validated CDSS as a digital front door can enhance preparedness, support safer navigation, and improve consultation efficiency in everyday care. The findings from this Post-Market Clinical Follow-up study strengthen the evidence base for the Ada CDSS, demonstrating safe and effective use within healthcare systems and outlining priorities for continued optimisation and post-market surveillance.

These trends increase demand while restricting the supply of clinical time, lengthening queues, and threatening timely access to appropriate care.

Before the visit, patients require support to determine whether care is needed, where to seek it, and how urgently; in some cases, empowering them with reliable information may enable safe self-management. During the visit, clinicians benefit from tools that improve efficiency and quality of the encounter. High documentation burden remains a persistent challenge: in acute care, overcrowding, often driven by non-urgent presentations, forces clinicians to take and record histories under time pressure, with frequent interruptions that increase the risk of omissions.\u003csup\u003e\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e\u003c/sup\u003e Documentation quality varies with experience: junior physicians may take three times longer to complete histories, while senior physicians are faster but sometimes less complete.\u003csup\u003e\u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e\u003c/sup\u003e Overstretching under these conditions is linked to higher error rates.\u003csup\u003e\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e\u003c/sup\u003e Structured, interactive, and pre-populated records have therefore been proposed as part of the solution, with digital history-taking tools offering the potential to improve clarity, accuracy, and completeness while reducing burden.\u003csup\u003e\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e\u003c/sup\u003e After the visit, technologies for monitoring and asynchronous communication can reduce unnecessary attendances, support adherence, and promote continuity.

The assessment generated a structured report including suggested conditions based on user provided information, a summary of entered symptoms, and urgency advice. Each suggested condition was paired with a condition-specific urgency recommendation, expressed using eight-point scale (Self-care, Self-care with pharmacy support, Primary care in 2\u0026ndash;3 weeks, Primary care in 2\u0026ndash;3 days, Primary care on the same day, Primary care within 4 hours, Emergency care, and Call ambulance). Physicians were asked to rate the appropriateness of urgency advice at two levels: (i) whether, based on the patient\u0026rsquo;s symptoms, the recommended advice for the most likely (top suggested) condition was reasonable, and (ii) whether the urgency advice levels across all suggested conditions were reasonable. In addition, the system generated an overall advice level (highest acuity across all advice suggestions), which was linked to the CUF care navigation options (Call Ambulance, Emergency Care, Video call with a General Practitioner). This overall advice level represented the guidance presented to the patient as the appropriate next step in care.\u003c/p\u003e \u003cp\u003eImmediately after the assessment, participants completed a survey, which captured completeness of symptom entry, preparedness for the upcoming consultation, and perceived psychological effects (e.g. anxiety).\u003c/p\u003e \u003cp\u003eFollowing the consultation, treating physicians were instructed to complete a structured survey immediately after seeing the patient, or at the latest by the end of the same working day. Where this was not possible, surveys were completed retrospectively using the patient record. In these retrospective cases, only a reduced set of items was addressed, focusing on the appropriateness of the report information (e.g. urgency advice, reasonableness of suggested conditions, completeness of the symptom list, and concordance of the report with the consultation focus and final diagnosis), whereas questions relating to the effect of the report on the consultation process itself were excluded. Physicians also reported whether the report prompted additional diagnostic tests or flagged critical findings. Further items evaluated consultation efficiency, time savings in specific activities, and perceptions of patient engagement and being informed.\u003c/p\u003e \u003cp\u003eParticipant and physician surveys combined Likert-type scales, categorical response options, and free-text fields.

Relationships between survey measures such as completeness, reasonableness, and perceived usefulness and physician-reported outcomes (efficiency, preparedness, perceived patient effects) were examined descriptively or, where appropriate, using the tests described above. For participant-reported outcomes, associations between completeness, preparedness, and anxiety reduction were evaluated similarly. Missing data were handled by excluding cases on a per-item basis.\u003c/p\u003e \u003cp\u003eContinuous variables were summarised as means with standard deviations or as medians with interquartile ranges, depending on distribution, and categorical variables were described using frequencies and percentages.

Table\u0026nbsp;\u003cspan refid=\"Tab2\" class=\"InternalRef\"\u003e2\u003c/span\u003e summarises these results. Physicians rated the overall urgency advice as appropriate in 77.6% (95% CI 70.1\u0026ndash;83.9), neutral in 13.7% (95% CI 8.5\u0026ndash;20.2), and not appropriate in 8.7% (95% CI 5.0\u0026ndash;13.9) (14/161). To understand whether advice judged not appropriate nonetheless resulted in safe user behaviour, the 14 cases in which the CDSS advice was rated not appropriate were examined and compared participants\u0026rsquo; actual care-seeking actions. In five of these cases (35.7%; 95% CI 12.8\u0026ndash;64.9), participants\u0026rsquo; actions matched what physicians considered appropriate, indicating that some users sought care consistent with clinical expectations even when the CDSS advice was inaccurate (Table\u0026nbsp;\u003cspan refid=\"Tab2\" class=\"InternalRef\"\u003e2\u003c/span\u003e).\u003c/p\u003e \u003cp\u003e \u003cdiv class=\"gridtable\"\u003e\u003ctable float=\"Yes\" id=\"Tab2\" border=\"1\"\u003e \u003ccaption language=\"En\"\u003e \u003cdiv class=\"CaptionNumber\"\u003eTable 2\u003c/div\u003e \u003cdiv class=\"CaptionContent\"\u003e \u003cp\u003eAppropriateness of care recommendation with actual participant behaviour comparison.

advice, within the same 14 cases, the CDSS\u0026rsquo;s highest (overall) advice level was compared with the physician\u0026rsquo;s recommended care-seeking behaviour. Physician responses for what the appropriate behaviour in 3 levels (\u0026ldquo;Managing symptoms at home or consulting a pharmacist\u0026rdquo;, \u0026ldquo;Consulting a GP\u0026rdquo; or \u0026ldquo;Consulting a specialist\u0026rdquo; and \u0026ldquo;Emergency Room / Emergency\u0026rdquo;) and were mapped onto the same eight-level CDSS advice scale (Appendix Table\u0026nbsp;2A). The CDSS recommendation coincided with the physician\u0026rsquo;s behaviour recommendation in nine cases (64.3%; 95% CI 35.1\u0026ndash;87.2) and was more cautious in five (35.7%; 95% CI 12.8\u0026ndash;64.9). Importantly, no instances were identified in which the CDSS provided a less urgent recommendation than physicians considered appropriate, indicating that all discrepancies reflected conservative rather than unsafe guidance. It should be noted that physicians\u0026rsquo; recommended behaviours were captured using a simplified three-level categorisation (self-care, primary care, or emergency care), whereas the CDSS generated advice across an eight-level scale. Consequently, apparent agreements may partly reflect differences in scale granularity rather than true clinical agreement.\u003c/p\u003e\n\u003ch3\u003eAppropriateness of the assessment report\u003c/h3\u003e\n\u003cp\u003eAppropriateness of the assessment report was evaluated across multiple dimensions, including the reasonableness of suggested conditions, completeness of the symptom list, concordance of the main problem with the consultation focus, inclusion of the physician\u0026rsquo;s most probable diagnosis, provision of additional useful information, and whether the report prompted further tests or flagged critical findings (Table\u0026nbsp;\u003cspan refid=\"Tab3\" class=\"InternalRef\"\u003e3\u003c/span\u003e).\u003c/p\u003e \u003cp\u003e \u003cdiv class=\"gridtable\"\u003e\u003ctable float=\"Yes\" id=\"Tab3\" border=\"1\"\u003e \u003ccaption language=\"En\"\u003e \u003cdiv class=\"CaptionNumber\"\u003eTable 3\u003c/div\u003e \u003cdiv class=\"CaptionContent\"\u003e \u003cp\u003ePhysician-reported survey outcomes on assessment report appropriateness and consultation impact.

In real-world use, the CDSS produced clinically appropriate reports, supported consultations, and was associated with positive patient experiences. Physicians rated the urgency advice as appropriate in the great majority of cases, indicating that the system effectively guided patients to a suitable level of care and performed safely within its intended purpose. Diagnostic agreement was also high, with physicians\u0026rsquo; most probable diagnoses commonly included among the system\u0026rsquo;s suggested conditions, confirming the clinical validity of the differential lists and their relevance to real patient presentations. The only clear exception was dermatology, where inclusion was considerably lower, a finding consistent with the fact that dermatological diagnosis depends largely on visual pattern recognition rather than symptom description. This difference highlights both the strengths and inherent limitations of a text-based DDSS, which performs best when diagnostic reasoning is driven by the patient\u0026rsquo;s reported history rather than visual assessment. Both physicians and patients reported feeling better prepared for the consultation, reflecting the system\u0026rsquo;s value in improving the structure and completeness of information at the point of care. These findings indicate that a CDSS can generate actionable information, combining appropriate care-level advice with plausible diagnostic hypotheses, while also structuring the underlying symptom and history information in ways that promote safer navigation and more efficient doctor\u0026ndash;patient interaction.\u003c/p\u003e \u003cp\u003eThe report produced by the CDSS represents a structured account of the patient\u0026rsquo;s history, bridging the pre-consultation and consultation phases. Its value lies in capturing the breadth of symptoms, translating them into plausible conditions, and presenting a concise problem summary for clinical review. When the consultation addressed the same problem reported by the patient in the assessment, the physician\u0026rsquo;s final diagnosis was commonly included among the suggestions. Evidence from computer-assisted history taking and patient-entered questionnaires shows that such structures improve completeness and data quality compared with unstructured note taking.\u003csup\u003e\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e,\u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e\u003c/sup\u003e They can also help clinicians identify relevant but unspoken symptoms, supporting diagnostic reasoning.

Associations between the perceived usefulness of condition suggestions and both preparedness and efficiency suggest that clinicians approached the consultation with a clearer differential.

Practical levers for improvement include automatic insertion of the report into the electronic medical record, reminders within scheduling software that alert clinicians when a patient has completed a pre-assessment and prompt report review before the consultation, training actions, and peer examples demonstrating efficiency gains.\u003csup\u003e\u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e21\u003c/span\u003e,\u003cspan citationid=\"CR22\" class=\"CitationRef\"\u003e22\u003c/span\u003e\u003c/sup\u003e\u003c/p\u003e \u003cp\u003eFrom the patient perspective, the CDSS improved both preparedness and led one-third of participants to feel less anxious. Participants who felt prepared were more likely to report reduced anxiety, and physicians noted that these patients arrived more engaged and informed. This sequence, from complete self-report to preparedness and lower anxiety, suggests that structured symptom assessment can foster confidence rather than amplify concern.

These factors may limit the extent to which the findings reflect all patient groups. In addition, results are drawn from a single, well-resourced private system with specific workflows. Performance and workflow impact may differ in public or resource-constrained settings. Replication in diverse health systems will be important to assess generalisability.

Conducted in Portugal\u0026rsquo;s largest private healthcare network, the study encompassed diverse specialties and care contexts, while predefined endpoints such as urgency advice appropriateness, diagnosis inclusion, and consultation efficiency provide structured evidence of performance. The prospective PMCF design, aligned with ISO 14155:2020, ensures regulatory and methodological rigour, strengthening the reliability and generalisability of the findings for assessing the safety, performance, and benefit of a CDSS in practice.\u003c/p\u003e \u003c/div\u003e"},{"header":"Conclusion","content":"\u003cp\u003eThe ESSENCE study provides real world evidence that a CDSS can effectively support safe, appropriate, and more confident decision making at the point of entry to care.

This study reports a post-market clinical follow-up (PMCF) evaluation of a clinical decision support system (CDSS), integrated into routine care within Portugal\u0026rsquo;s largest private healthcare network (CUF) to determine whether it can deliver appropriate urgency advice and clinically useful reports, and whether its use is associated with improved preparedness and consultation efficiency in real-world practice.\u003c/p\u003e\u003ch2\u003eMethods:\u003c/h2\u003e \u003cp\u003eThis was a prospective, observational study. Adults aged\u0026thinsp;\u0026ge;\u0026thinsp;18 years completed a full symptom assessment via the myCUF application before consultation. Participants provided informed consent and completed a post-assessment survey; treating physicians completed structured post-consultation surveys. Primary endpoints were the appropriateness of urgency advice and of the assessment report, including the reasonableness of suggested conditions, completeness of symptom history, concordance of the main problem with the consultation focus, and inclusion of the physician\u0026rsquo;s final diagnosis. Secondary endpoints included consultation efficiency and time saving, clinician preparedness, confidence in diagnosis, and perceived usefulness of the assessment report information. Analyses used descriptive statistics, confidence intervals, risk differences and risk ratios, with subgroup comparisons by specialty, sex, and age.\u003c/p\u003e\u003ch2\u003eResults:\u003c/h2\u003e \u003cp\u003eA total of 1,470 participants completed the post-assessment survey. Physicians returned 163 consultation surveys, of which 60 were based on reports reviewed before the encounter and formed the basis for efficiency and preparedness analyses. Urgency advice was judged appropriate in most cases (top advice level: 74.1%, 120/161; 95% CI 67.4\u0026ndash;80.1; all advice levels: 77.6%, 125/161; 95% CI 70.1\u0026ndash;83.9), with no significant differences by specialty, sex, or age. In cases where advice was not considered appropriate (8.7%; 95% CI 5.0\u0026ndash;13.9), all disagreements reflected conservative, over-cautious advice; no instances of under-triage were identified. Report appropriateness was high: conditions provided as suggestions were judged reasonable in 73.0% (119/163; 95% CI 65.7\u0026ndash;79.5), the symptom list was considered complete in 78.4% (127/162; 95% CI 71.2\u0026ndash;84.4), the main problem discussed in the consultation matched the information in the report in 82.8% (135/163; 95% CI 76.1\u0026ndash;88.2), and the clinician\u0026rsquo;s most likely diagnosis was included among the suggested conditions in 80.4% (131/163; 95% CI 73.5\u0026ndash;86.0). Physicians reported efficiency improvements in 66.7% (40/60; 95% CI 53.3\u0026ndash;78.3) and time savings in 66.1% (39/59; 95% CI 52.3\u0026ndash;77.6), most often during the consultation itself. Increased preparedness for the consultation was reported in 71.7% (43/60; 95% CI 58.6\u0026ndash;82.5) and was strongly associated with the perceived usefulness of the condition suggestions. Among participants, 80.5% (1,183/1,470; 95% CI 78.4\u0026ndash;82.5) reported that all symptoms were captured in the assessment report, 71.2% (1,046/1,470; 95% CI 68.7\u0026ndash;73.6) felt more prepared for the consultation, and 33.0% (485/1,470; 95% CI 30.5\u0026ndash;35.6) reported reduced anxiety after assessment completion.
