Abstract

Importance. Data, information and knowledge in health care has expanded exponentially over the last 50 years, leading to significant challenges with information overload and complex, fragmented care plans. Generative AI has the potential to facilitate summarization and integration of knowledge and wisdom to through rapid integration of data and information to enable efficient care planning. Objective. Our objective was to understand the value of AI generated summarization through short synopses at the care transition from hospital to first outpatient visit. Design. Using a de-identified data set of recently hospitalized patients with multiple chronic illnesses, we used the data-information-knowledge-wisdom framework to train clinicians and an open-source generative AI Large Language Model system to produce summarized patient assessments after hospitalizations. Both sets of synopses were judged blinded in random order by clinician judges. Participants. De-identified patients had multiple chronic conditions and a recent hospitalization. Raters were physicians at various levels of training. Main outcome. Accuracy, succinctness, synthesis and usefulness of synopses using a standardized scale with scores > 80% indicating success. Results. AI and clinicians summarized 80 patients with 10% overlap. In blinded trials, AI synopses were rated as useful 75% of the time versus 76% for human generated ones. AI had lower succinctness ratings for the Data synopsis task (55-67%) versus human (84-86%). For accuracy and synthesis, AI had near equal or better scores in other domains (AI: 72%-79%, humans: 68%-84%), with best scores from AI in Wisdom. Interrater agreement was moderate, indicating different preferences for synopsis content, and did not vary between AI and human-created synopses. Discussion. AI-created synopses that were nearly equivalent to human-created ones; they were slightly longer and did not always synthesize individual data elements compared to humans. Given their rapid introduction into clinical care, our framework and protocol for evaluation of these tools provides strong benchmarking capabilities for developers and implementers.

Question Can a Generative AI Large Language Model be trained to generate accurate and useful patient synopses through chart summarization for use in outpatient settings after hospital discharge? Findings Using a Data-Information-Knowledge-Wisdom framework, clinicians and an open-source AI system were trained to summarize charts; these synopses were rated blindly using a standardized index. Synopses from the AI were rated as useful 75% of the time versus 76% for human generated ones, AI synopses scored highest in Wisdom for accuracy and synthesis. Interrater agreement was moderate but did not vary between AI and human. Meaning This study provides a concrete, replicable protocol for benchmarking LLM summarization outputs and demonstrates general equivalence to human-created synopses for outpatient use after care transitions. Introduction Health care delivery has become a data and knowledge intensive exercise, especially when caring for those with complex conditions. For instance, persons living with Multiple Chronic Conditions utilize more health care and suffer exponentially worse outcomes than those with one or zero conditions. This is especially true of those with five or more conditions, who have ninety times the risk of hospitalization, are on an average of eight long term prescriptions, and see twelve different providers per year. 1 - 5 Managing the needs of these patients in the context of outpatient visits is nearly impossible – estimates are that addressing the acute, preventive, and chronic illness needs of the patients for a single primary care physician would take 26 hours a day. 6 Exacerbating this problem in the United States are the requirements for medical documentation. Billing expectations have led to notes that are highly redundant and up four-times longer than elsewhere in the world. 7 - 9 These expectations also necessitate more frequent documentation by care team members, where information must be duplicated across different notes to facilitate billing, leading to substantial bloat and making concise communication difficult. A major focus of ambulatory care teams and our previous research is care planning 10 , 11 , which can be defined as the proactive co-creation of an integrated treatment plan that incorporates patient health needs, values, and preferences. Care planning requires significant time to forage through data, derive current and relevant information, incorporate knowledge of guideline-based recommendations, and leverage the wisdom and experience of the care team and patient into the process. The care planning process is often summarized in the assessment and plan in notes, where a brief overall summary of the key information and recommendations are included. Care planning is challenging for several reasons, including the burdens of finding and extracting relevant information from clinical data, summarizing that information in a meaningful way, and incorporating appropriate clinical recommendations based on patient needs and preferences. Time to create care plans is substantial, and errors from missed information are common. These burdens have led to substantial burn-out amongst ambulatory care teams, with 30% of clinicians reporting burn-out and 50% of these indicating the EHR worsened their burn-out. 12 Novel solutions exist. Generative AI models built on large textual corpora (called Large Language Models, or LLMs) generally use large neural networks (sometimes with more than 10 26 elements) to predict what text should come next. Studies have shown benefits in auto-composing responses to patient questions, generating differential diagnoses from cases, and generating notes from ambient recordings. 13 As a baseline, we sought to understand the ability of a set of advanced but generalized LLMs to produce clinically meaningful summaries from patient data with complex needs. Background As described above, the major challenges involved in care planning can be broken into three broad steps: information identification and extraction, summarization, and appropriate recommendations. For care planning, one framework for summarization can be defined through the data, information, knowledge, and wisdom model. 14 - 17 In this model, data are individual elements relevant to care planning; information is data with patient context, such as a condition (diabetes) with A1c and diet and activity self-management; knowledge incorporates evidence about diagnoses, prognosis, monitoring and effective treatments; and wisdom incorporates values, preferences, and needs that allow a care plan to be most aligned with the wishes of the patient. Identification, extraction, and prioritization of clinical information EHRs have received substantial criticism for their cognitive burden and lack of usability in data finding and navigating, requiring significant expertise to gain full efficiency without substantial cognitive load. Data are fragmented, both within electronic systems and between settings of care. Gathering these data together – referred to as ‘foraging’ in the vernacular – takes substantial time and effort. Often a step known as ‘scrubbing’ helps to identify key information before outpatient visits to streamline care; observational studies of providers before, during, and after visits demonstrate a substantial (up to an average of 12 minutes per patient) 18 , 19 amount of time gathering information to understand what to ask; how to act on what has been learned; and assure themselves that these actions were complete and appropriate. Prioritization of these data is crucial: the volume of information available far outstrips the ability of an individual to consume and process it 20 , leading to substantial errors. 21 Summarization of information to provide patients with knowledge A common aspect of training in medicine is to summarize key findings from complex patients in brief, clearly understood statements. Chart summarizations, synopses, and other documents serve to make it easier to quickly understand trends, new concerns and data, and other relevant information. 22 LLMs now achieve very high performance with providing clinical summary and a progressively lower barrier for utilization. 23 - 25 However, the ability to implement flexible and adaptive summarizations is still challenging, requiring extensive technical experience. Pivovarov and Elhadad summarized the work up to 2015, identifying significant work in removing redundancy, determining salience, and taking advantage of clinical knowledge; they highlight slow uptake of these systems. 26 In 2017, Pivovarov published an extraction tool that identified salient concepts and presented them to quality metric summarizers, highlighting a 50% reduction in summarization time. 27 In 2019, Liang, Tsou, and Poddar created a machine learning disease specific text summarization, achieving moderate agreement with human annotators (AUC .67-.74). 28 Recent, cutting-edge word representation models, such as BERT, have been shown to be effective at biomedical text mining via extensive training on biomedical corpora, now termed bioBERT. 29 - 31 More recently, GPT-4 was utilized to compare LLM clinical summaries to medical expert review and demonstrated up to 36% of AI-generated summaries were superior to medical experts and up to 45% of AI summaries were deemed equivalent. 23 As summarization technology improves, benchmarking has also been developed to establish a standard on the efficacy of NLM models in biomedical data summarization. 32 While promising, prior work has failed to address the core outpatient summarization steps that are required for care planning. With the advent of Generative AI tools, it may be possible to better replicate these steps. We performed a structured evaluation of these steps in order to both set a benchmark for LLM performance as well as share a structured evaluation protocol. Methods Overview We conducted a non-inferiority trial to determine if a generalist LLM (Llama-8-3b) 33 was able to perform comparably to human clinicians in the generation of actionable clinical synopses of discharge notes and associated structured data. Specifically, these synopses were intended to guide outpatient care for patients with Multiple Chronic Conditions after discharge from the hospital. We used the Data-Information-Knowledge-Wisdom framework to model different approaches to synopsis generation. The quality of clinician- and LLM-generated synopses were judged and then compared using a blinded design informed by the Physician Documentation Quality Instrument (PDQI). 34 The study design is summarized in Figure 1 . The OHSU Institutional Review Board determined this work to be not human subjects research (STUDY00026857). Download figure Open in new tab Figure 1. Study framework and design Data After completing all relevant agreements and trainings on PhysioNet 35 (see appendix), we used de-identified patients from the MIMIC-III database with multiple chronic conditions and significant outpatient follow-up needs. Based on our work in the eCarePlan project, we selected patients with a recent hospitalization with multiple chronic conditions for whom care planning was challenging due to the complexity of their needs. For multiple chronic conditions, we used a subset of conditions from the Chronic Condition Warehouse (see Appendix Table 1). 36 We also leveraged the CLIP study 37 , which abstracted action items from discharge summaries for outpatient follow-up; patients who were part of the study and were discharged to home or home health were included. Synopsis Authoring and Prompt Engineering As noted above, the generalist LLM and our human authors were asked to generate four synopses of each assigned discharge note and associated structured data, following the D-I-K-W framework. The high-level steps were to: identify and summarize key observations, conditions, treatments, and needs (data); contextualize these data (information); integrate evidence-based guidelines (knowledge); and incorporate social and behavioral needs with overall health for person-centered care planning (wisdom). The protocol and instructions for the synopsis authoring task provided to clinicians and final prompts for the LLM are available as supplemental materials. The LLM was not provided with additional documents for knowledge, instead relying on its generalist training. An iterative process was used to develop LLM prompts and instructions for human authors. First, high-quality synopses adhering to the DIKW framework were written for five example patients. Instructions to guide human authors through the process of developing similar synopses were written and revised based on feedback from clinicians. In parallel, a trained data scientist (S.B.) created prompts with the LLM (Lllama-3 8B) for data, information, knowledge and wisdom, and ran the prompts ten times each for the five example patients and five additional training patients. An investigator then rated the AI-produced synopses’ accuracy, synthesis, and conciseness (see Synopsis Rating section for more details) and provided guiding notes. The prompts were revised and re-run until at least eight of the ten resulting iterations were judged as successful on at least two of these three criteria for each AI-produced synopsis. Synopsis Rating For the LLM to human comparison, we asked reviewers to grade each pair of synopses in a blinded, randomized fashion. Training consisted of presentation of the same example synopses with example scores. Human-and LLM-generated synopses were rated by clinicians on four of the fifteen PDQI constructs: accuracy, synthesis, conciseness, and usefulness, all rated with a 5-point Likert scale. 10% of the synopses were rated twice, with a total of 512 duplicated ratings (8 patients x 4 synopses x 2 creators x 4 ratings x 2 raters). Raters were presented with the source data (discharge notes and accompanying structured data) and with the data, information, knowledge, or wisdom synopsis to be rated. Analysis We calculated descriptive statistics for patient demographics, clinical characteristics, and source data (note length and number of structured concepts). Human- and LLM-generated synopses were characterized according to length and, through the application of cTakes version 4.0, 38 the number of relevant clinical concepts included. We analysed the adequacy of the prompt engineering through graphic comparison of variability with a goal of reaching consistent performance. Rater agreement was assessed with Krippendorff’s Alpha and the Intraclass Correlation. The former measures the likelihood precise agreement is due to chance, while the latter measures rater reliability. Non-inferiority analyses were completed to compare the succinctness, accuracy, usefulness, and synthesis of the LLM-generated synopses compared to the human-generated synopses generated on the same patient. For analysis purposes, the ratings were dichotomized: a synopsis was successful according to a given construct if the assigned rating was a 4 (mostly) or 5 (very). Clinically significant differences were set at 5%, where 1 of 20 synopses didn’t meet criteria. Statistical analysis compared differences between LLM and human response through the Fisher’s exact test, with the McNemar test for uneven rates of false positives and false negatives. These analyses were performed for the data, information, knowledge, and wisdom synopses separately. Results Sixty-four patients were summarized by both the LLM and Humans, with 8 double summarized (12%). Table 1 provides descriptive statistics for the patients. In all, synopses were written on 64 patients; 61% were male; 80% white; and the most common diagnoses were hypertension, ischemic heart disease, diabetes, and cancer. Compared to the MIMIC3 distribution overall, the selected sample was slightly younger (MIMIC3 median age 66); slightly more male (MIMIC3 56% male).

All differences between Clinician- and LLM-generated summaries were significant under the Wilcoxon rank sum test with an alpha of 0.05 (p<0.001 in all cases). Prompt engineering iterations The initial and final prompts used are in the Supplement. Figure 2 displays the median and range of scores rated as successful out of 10 LLM generations across the 10 example patients. For Data, the median of scores met the 80% threshold, but scores as low as 30% were seen. For information, 2 of 3 ratings met criteria, with wide variation in succinctness on initial runs. For Knowledge, 2 of 3 met criteria, with synthesis both poorly performing (50% median success rate) and variable (0-100% range). Wisdom met all three criteria but had highly variable accuracy and succinctness. All prompts were changed to reflect this initial review. LLM and Human blinded comparison Raters scored all synopses in a blinded fashion; across all 4 statistics, the % of successful scores was 76.9% for AI and 82.6% for humans. As shown in Figure 3 , AI performed at similar success levels to humans in Accuracy across Data, Information, and Wisdom, with an 8% decreased success in Knowledge. The AI generally rated much worse in Succinctness than humans, with 19-36% more AI synopses failing Information, Knowledge and Wisdom. Data Synopses from the AI were judged more succinct. For synthesis, AI was much worse than humans for data; but similar in Information and Knowledge synopses. Eight percent more AI-produced Wisdom synopses met success criteria than humans. For usefulness, the AI rated worse in Data, the same in Information and Knowledge, and much better in Wisdom (+11% success rate), with 75% of AI responses rated as useful compared to 76% for humans.

Success ratings (4 or 5) for AI and Human-produced synopses across Data, Information, Knowledge, and Wisdom Categories. Agreement. Of the 10% of synopses that were double rated, Krippendorff’s Alpha was moderate (.224) for precise agreement – 3 raters had higher overall scores versus the other two. However, the intraclass correlation for raters was high (.92), indicating overall reliability. Neither varied for the ratings for human and AI-generated synopses. Discussion The advent of Generative AI capabilities, especially for text production, have enabled a new set of health documentation and communication capabilities, including text generation, explanation, and summarization. 23 - 26 , 28 - 32 In this study, we successfully completed a rigorous protocol for benchmarking a clinically relevant data summarization tool. Our results showed that iterative fine tuning of a generative AI model produced brief summaries of patient needs after hospitalization that were non-inferior to human-created ones in synthesis and usefulness and potentially superior in more holistic, wisdom-based reflections. The succinctness of its summarizations varied, with Data synopses by the AI rated highly succinct, but all other categories were not succinct. There seemed to be a trade-off between succinctness and other categories – synthesis and usefulness were both rated much lower for the AI than humans in data, while less succinct AI synopses rated more highly. We were able to train this generalist Generative AI tool to generate results zero-shot fashion (albeit with chaining) and achieved high performance through careful prompt engineering. The creation and testing of prompts is a crucial aspect of fine-tuning any model; for ours, it required several iterations with repeated rating to achieve reasonable scores. These prompts are available in the Appendix. The value of this work is three-fold. First, it demonstrates the relative performance of LLMs in these common, time-consuming summarization tasks as compared to humans across a set of standard measures. Second, it provides a robust, reproducible protocol for others to use as they train, evaluate, and implement LLMs; we provide the full protocol, including the prompts, instructions, and examples and invite others to replicate our experiment and benchmark their own LLMs. Third, and perhaps most usefully, it parses summarization into different levels based on a key framework originally from nursing – Data-Information-Knowledge-Wisdom – that will allow others to better specify their specific solution and parse errors in a more granular fashion. It also facilitates chaining – moving from less to more integrative tasks through serial steps – which are a particular strength of LLMs. Thus, it provides a useful model on which others may build. Summarization may be one of the greatest features of LLMs: pulling out the most common ideas and themes from extensive documents (16, 19-20,22). The burden both of producing and reading documentation is one being addressed in several areas, including through a program intended to reduce documentation burden by 25% in five years. 39 The utility of accurate and thoroughly synthesized synopses for patients with significant illness burden or after care transitions is particularly high. Limitations. The data we used was not wholly representative of data for patients with complex needs; we limited available data and MIMIC-III is a subset of high-risk patients. Performance may vary across different populations. LLMs are known to hallucinate; although we scored the synopses on accuracy, automation bias may have led raters to accept confident statements as truth. This was most likely in the Knowledge section, where the LLM quoted key guidelines that it had previously consumed: raters may not have checked these. Adding quantitative checks for hallucinations and additional LLM verification layers are the next steps to address this weakness. The PDQI scores we used had moderate agreement on scores, indicating variability in preference for synopses; this variability was the same for humans and AI. Future work. Expanding beyond discharge summaries is a crucial next step for outpatient visit synopses. Adams et al. (2021) reviewed the nature of hospitalization summaries by constructing a dataset of 109,000 patients; they find discharge summaries to be highly concise, somewhat comprehensive, and with unique organization compared to other notes. 40 Thus, summarizing other note types into synopses may prove difficult. This is especially poignant given Kripalani’s findings that discharge summaries lack many elements that may require follow-up. 41 Conclusions We created a protocol to benchmark LLMs for synopsis creation after hospital discharge using a Data-Information-Knowledge-Wisdom framework. We tested the protocol on an open-source LLM and blind-rated its outputs versus those of humans, achieving similar success rates for usefulness, worse scores for succinctness, and better scores in the Wisdom task.
