We sought to develop a risk prediction model to identify chronic complications in children with ASA. Methods This retrospective observational study enrolled children (ages one month to 18 years) diagnosed with ASA who were hospitalized at a tertiary pediatric hospital between 2016 and 2023. We documented clinical management, complication status, and sequelae, and constructed a multivariate logistic regression model for predicting chronic complications. Results A total of 95 children were identified, 16.8% of whom experienced chronic complications from ASA over a 12-month follow-up period. Univariate logistic analysis identified the following factors associated with chronic complication development: white blood cell (WBC), serum amyloid A (SAA), hematocrit, hemoglobin, mean platelet volume, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) on admission; SAA, hematocrit (HCT), and hemoglobin (HGB) at discharge; bacteremia; Staphylococcus aureus detection; bone abscess; delayed source control; bone debridement; isolated arthritis; and arthritis combined with dislocation or subluxation (all p < 0.05). On further multivariate logistic regression analysis, we identified four independent predictors: WBC on admission (OR = 1.165, 95% CI: 1.038–1.308), ALT on admission (OR = 1.014, 95% CI: 1.004–1.025), SAA at discharge (OR = 1.153, 95% CI: 1.029–1.292), and arthritis combined with dislocation or subluxation (OR = 28.134, 95% CI: 3.691–214.431). The area under the receiver operating characteristic (ROC) curve was 0.882 (95% CI: 0.786–0.979). The logistic regression model formula was: Log(P) = -8.459 + 0.153×WBC on admission + 0.014×ALT on admission + 0.142×SAA at discharge + 3.337×arthritis combined with dislocation or subluxation. Conclusion The prediction model for chronic complications of pediatric ASA incorporates four key variables: WBC on admission, ALT on admission, SAA at discharge, and arthritis combined with dislocation or subluxation. This model has been shown to effectively predict chronic complication risk in children with ASA. Acute suppurative arthritis Children Risk prediction Chronic complications Nomogram Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Introduction Acute suppurative arthritis (ASA) is an infection of the synovial joints, predominantly affecting young children. In developed countries, the incidence of pediatric ASA ranges from 1–5 per 100,000 children [1]. Notably, ASA is a potentially destructive condition, with a high rate of severe and long-term complications in growing children [2]. Chronic complications associated with ASA include growth arrest, pathological fractures, avascular necrosis, joint stiffness, chronic dislocation, and joint deformities. Furthermore, infection recurrence may occur in cases of inadequate treatment or poor treatment compliance [3]. However, the variable clinical courses observed in pediatric patients have hindered the development of standardized management guidelines. Furthermore, in Asia, osteoarticular pathogens like Staphylococcus aureus show different characteristics compared to similar pathogens in the United States and Europe. This highlights the need for custom prediction models [4, 5]. Most existing studies on ASA have primarily relied on retrospective analyses to identify factors associated with chronic complications and disease prognosis [2,3,6–8]. In 2023, Gouveia et al. became the first to successfully develop and validate a risk prediction model for acute and chronic complications in children with osteoarticular infections [9]. The primary objective of our study was to develop a nomogram to predict chronic complications in pediatric patients with ASA. The secondary aim was to compare the newly developed nomogram with the Gouveia system [9] previously reported. Methods We conducted a retrospective review of the medical records of children between one month and 18 years of age who were hospitalized at our institution between January 2016 and December 2023 with ASA and symptoms lasting no longer than 14 days before admission. The Ethics Committee of our Institution approved this study (No. [2025]242A01). The inclusion criteria for this study were: (1) patients aged 1 month to 18 years; (2) patients with confirmed diagnosis of ASA; (3) patients whose symptoms began within 14 days before admission; (4) patients with at least one year of follow-up after the first onset of symptoms. The exclusion criteria were: (1) patients with pre-existing disease, such as blood disease, category of impediment disease, or cardiovascular disorder; neoplasm malignant; or other chronic disease; (2) patients diagnosed with juvenile arthritis, synovitis, pulmonary tuberculosis, immunological disease, or arthritis reactive after admission; (3) patients with osteomyelitis of flat bones, irregular bones, or small bones (e.g., vertebral column, jawbone, clavicle, or metacarpal bone), septic arthritis of small joints, or secondary infection after open fracture or surgery; (4) exclusion criteria also included patients with follow-up duration less than 1 year. Diagnostic criteria The direct and indirect diagnostic criteria for Acute suppurative arthritis are as follows: - Direct diagnosis is established if pathogenic microorganisms are detected in blood, pus, or tissue cultures. - Indirect diagnosis can be made when cultures are negative but symptoms such as dysphoria, local swelling, pain, limited range of mobility, elevated C-reactive protein (CRP) levels, imaging signs, or positive Magnetic resonance imaging (MRI) are present. Body fluid or tissue cultures can be obtained through joint incision and drainage, Bone abscess drainage, or Biopsy bone. Cultures from joints or soft tissues near the site of bone infection can also be used. For disseminated infections, cultures from various sources such as mediastinal fluid or pleural fluid are used. Chronic complications and scoring Chronic complications include Growth arrest, Pathological fracture, Ischemic necrosis, joint ankylosis, limited range of joint mobility, Chronic dislocation, Joint deformity and Osteomyelitis chronic. Osteomyelitis chronic is defined as persistent or recurrent symptoms and signs related to epiphyseal, metaphyseal or skeletal changes visible on plain X-ray. It requires at least 12 weeks of Antibiotic therapy. In the Gouveia scoring system, the final model for estimating the probability of sequelae at 6 months is πSeq-6 = OddsSeq-6/1.01 + OddsSeq-6, where OddsSeq-6 = exp [-4.75 + 1.41· (age ≥ 4 years) + 1.52· (CRP ≥ 110 mg) + 2.22·disseminated disease + 1.70·Bone abscess] [9]. Statistical Analysis Data analyses were performed using SPSS version 27.0 (International Business Machines Corporation, Armonk, NY, USA). Normally distributed quantitative data were presented as mean (standard deviation), and non-normally distributed quantitative data as median (P25, P75). Categorical data were described by frequencies and proportions. For between-group comparisons, independent samples t-tests were used for normally distributed quantitative data, nonparametric tests for non-normally distributed data, and chi-square tests for categorical data. Missing values were handled via multiple imputation. Univariate analyses were conducted for all variables; statistically significant factors were included in a stepwise backward multiple logistic regression model. Using R software version 4.2.2 (R Core Team, Auckland, New Zealand), a nomogram for predicting childhood ASA chronic complications was developed based on identified independent predictors. The model was optimized by 1000 bootstrap iterations, and its predictive performance was internally validated via receiver operating characteristic (ROC) curves. The Hosmer-Lemeshow test evaluated the goodness-of-fit between predicted and observed outcomes, and calibration curves assessed calibration. Decision curve analysis quantified the nomogram's net benefit across threshold probabilities to validate its utility. A p-value < 0.05 was considered statistically significant. The Gouveia scoring system was applied to predict cohort data risks, enabling direct performance comparison with the present study's nomogram. Results This study enrolled 95 patients with ASA, including 51 males (53.7%) and 44 females (46.3%) (Fig. 1 ). Table 1 and Table 2 present the demographic and clinical details (Table 1 and Table 2 ). Among these cases, 71 (74.7%) were diagnosed with isolated septic arthritis, 16 (16.8%) with septic arthritis complicated by osteomyelitis, 7 (7.4%) with arthritis accompanied by dislocation or subluxation, and 1 (1.1%) with multifocal infection. Regarding laterality, ASA affected the left side in 54 patients (56.8%) and the right side in 41 patients (43.2%). The most commonly involved joints were the hip (n = 34, 35.8%) and knee (n = 31, 32.6%). Table 1 Relationship between predictive and outcome variables and chronic complications in children with ASA.

The median age at onset was 0.83 years. Prior to admission, 54 patients (56.8%) had received antibiotic treatment. On admission, 30 patients (31.6%) presented with fever; 27 patients (28.4%) remained febrile 48 hours after initiation of empirical intravenous antibiotics, and 12 patients (12.6%) had a CRP level ≥ 100 mg/dL within 2–4 days of treatment. The median symptom duration was 7 days, and the median total hospital stay was 15 days. Empirical antibiotic therapy was generally initiated on the day of admission, with definitive antibiotic treatment starting at a median of one day post-admission (range, 11 to 20.75 days). The median duration of antibiotic therapy was 15 days, and 45 patients (54.2%) required a switch in antibiotics during hospitalization. Microbiological cultures were performed for all patients. Blood culture yielded positive results in 19 of 94 cases (20.2%), while cultures of pus, synovial fluid, or tissue were positive in 42 of 76 cases (55.3%). Overall, 47 patients (50%) had positive microbiological cultures. Staphylococcus aureus was identified in 26 cases, including 15 strains (31.9%) of methicillin-sensitive Staphylococcus aureus and 7 strains (14.9%) of methicillin-resistant Staphylococcus aureus. There were also 6 cases (12.%) of Staphylococcus hominis, 9 cases (19.1%) of Salmonella [4 cases (8.5%) of S. Typhimurium, 2 cases (4.3%) of S. enteritidis, 1 case (2.1%) of S. Riphium, 1 case (2.1%) of S. Potsdam, 1 case (2.1%) of S. Chester], 2 cases (4.3%) of Streptococcus pneumoniae, 2 cases (4.3%) of Streptococcus Agalactiae (group B), 1 case (2.1%) of Acinetobacter baumannii, 1 case (2.1%) of Bacillus Cereus, 1 case (2.1%) of Proteus species. Osseous abscesses were detected in 16 patients (16.8%), 2 of whom (2.1%) had concurrent disseminated infection. Within 72 hours of admission, 79 patients (83.2%) received active intervention, including 21 patients (22.1%) who underwent bone debridement. Delayed intervention (> 72 hours) was performed in 26 patients (31%), and 10 patients (10.5%) required multiple surgical procedures during hospitalization. Chronic Complications Of the 95 patients, 16 (16.8%) experienced chronic complications. These included 8 cases of avascular necrosis, 6 cases of growth arrest, 4 cases of chronic dislocation, 2 cases of joint deformity, 3 cases of joint ankylosis, and 1 case of pathological fracture. Univariate Logistic Regression Analysis Several factors were identified to be associated with complications of chronic osteoarticular infections (OAIs), with statistical significance (p < 0.05) (Table 1 ). These factors included white blood cell count (WBC), serum amyloid A (SAA), hematocrit (HCT), hemoglobin (HGB), mean platelet volume (MPV), alanine transaminase (ALT), and aspartate transaminase (AST) on admission; SAA, HCT, and HGB at discharge; as well as bacteremia, detection of Staphylococcus aureus, bone abscess, delayed source control, bone debridement, isolated arthritis, and arthritis combined dislocation or subluxation. Multivariate Regression Analysis and Prediction Model Establishment Seventeen variables with statistical significance in the univariate analysis of ASA were included in the multivariate analysis. Backward stepwise Logistic regression was employed, and the results revealed that WBC on admission, ALT on admission, SAA at discharge, and arthritis combined dislocation or subluxation were independent predictors of chronic complications in ASA patients (p < 0.05) (Table 3 ). The resulting regression model was expressed as: Log(P) = -8.459 + 0.153×WBC on admission + 0.014×ALT on admission + 0.142×SAA at discharge + 3.337×arthritis combined with dislocation or subluxation. Based on this logistic regression equation, we developed a nomogram for predicting chronic complications (Fig. 2 ).

The area under the curve (AUC) was 0.882 (95% confidence interval [CI]: 0.786–0.979), indicating high predictive accuracy (Fig. 3 ). The optimal cut-off value was determined to be 0.427, at which the sum of sensitivity and specificity reached the maximum: sensitivity was 66.7%, specificity was 96.1%, positive predictive value (PPV) was 76.9%, negative predictive value (NPV) was 93.7%, and overall accuracy was 91.3%. These results demonstrated good discriminative ability of the model (Table 4). The Hosmer-Lemeshow test yielded a p-value of 0.447, suggesting no significant deviation from perfect fit and confirming the model's satisfactory predictive accuracy. The calibration curve, which compared predicted outcomes with actual results, further verified the reliability of the model in the validation set (Fig. 4 ). Decision curve analysis (DCA) demonstrated the clinical utility of the model by showing its net benefit across the threshold probability range for predicting chronic complications in ASA patients (Fig. 5 ). A comparative study of the prediction model for chronic complications in pediatric ASA patients was conducted using the Gouveia et al. scoring system [9] (Table 4). When the Gouveia et al. scoring system was applied to predict the risk of chronic complications in the same patient cohort, the AUC was 0.551 (95% CI: 0.395–0.708). At the cut-off value of 0.041, the system achieved a sensitivity of 43.8%, specificity of 81%, PPV of 31.8%, NPV of 87.7%, and overall accuracy of 74.7%. Discussion This population-based study revealed that the following factors may be associated with chronic complications in the prognosis of pediatric ASA: WBC, SAA, HCT, HGB, MPV, ALT and AST on admission; SAA, HCT, HGB at discharge, bacteremia, staphylococcus aureus detection, bone abscess, delayed source control, bone debridement, isolated arthritis and arthritis combined dislocation or subluxation. Further multivariate analysis revealed that WBC on admission, ALT on admission, SAA at discharge, and arthritis combined with dislocation or subluxation were independent risk factors for chronic complications in these patients. Elevated WBC count is a hallmark of suppurative arthritis, reflecting bacterial load and inflammatory intensity [10,11]. Persistent leukocyte infiltration activates the complement system via enzymatic hydrolysis, cell death, and cytokine release; complement then amplifies inflammation through leukocyte chemotaxis and activation [12–14], ultimately leading to inflammatory escalation and tissue damage. During infection, the liver participates in the acute-phase response by synthesizing acute-phase proteins (e.g., SAA, CRP) to regulate systemic inflammation [15]. Concurrently, hepatocytes may be injured by inflammatory mediators (e.g., tumor necrosis factor-α, interleukin-6) [16–18], forming an "inflammation-hepatic damage" vicious cycle that causes ALT release into the bloodstream. Elevated admission ALT may thus reflect both the magnitude of the host inflammatory response and liver involvement in inflammation. Notably, direct studies exploring the association between admission ALT and ASA prognostic risk remain limited, warranting confirmation in future prospective investigations. Serum SAA levels rise precipitously following infection: during the acute-phase response to tissue injury, approximately 2.5-3% of hepatic protein synthesis is dedicated to SAA production, enabling plasma concentrations to increase from 1–5 µg/mL to 1000 µg/mL within 24 hours [19,20]. This elevation persists for 2–3 days (circulating SAA half-life ≈ 90 minutes) and normalizes within 7–10 days if tissue injury resolves [21,22]. A higher SAA level at discharge may therefore indicate unresolved inflammation and ongoing tissue damage. Previous studies have shown that acetabular dysplasia often persists during follow-up in children with ASA complicated by dislocation or subluxation, suggesting severe joint damage [23]. For instance, dislocation of the hip joint, which is a ball-and-socket joint characterized by an extensive range of motion and a thick articular capsule, can readily compress periarticular blood vessels, thereby leading to femoral head avascular necrosis [24,25]. Calculating chronic complication risk scores during hospitalization aids in determining optimal management strategies. Over 90% of patients who develop chronic complications do so within one year of admission, supporting the rationale for one-year follow-up in high-risk patients [3,26,27]. When elevated risk is predicted, orthopedic surgeons should recommend extended outpatient follow-up to closely monitor complication development and provide families with guidance on prevention strategies. In our ASA cohort, arthritis with dislocation emerged as a strong independent risk factor (B = 3.337, χ²=10.368, P = 0.001), with an odds ratio (OR) of 28.134 (95% CI: 3.691-214.431), indicating a 28.134-fold higher risk of chronic complications compared to patients without dislocation. Three laboratory markers also showed significant positive associations: each 1-unit increase in admission WBC count was associated with a 16.5% increased risk (OR = 1.165, 95% CI: 1.038–1.308, P = 0.009); each 1-unit increase in admission ALT with a 1.4% increased risk (OR = 1.014, 95% CI: 1.004–1.025, P = 0.006); and each 1-unit increase in discharge SAA with a 15.3% increased risk (OR = 1.153, 95% CI: 1.029–1.292, P = 0.014). These variables demonstrated good discriminative ability for predicting 1-year chronic complications. Given the accessibility of these risk variables, we compared our nomogram to the Gouveia scoring system. While the Gouveia system [9] has demonstrated satisfactory predictive performance within the local cohorts, our findings indicate that the nomogram exhibits superior discriminatory ability, particularly among Chinese patients. The nomogram's AUC of 0.882 (95% CI: 0.786-0.979) significantly surpasses the moderate prediction level threshold of 0.7, indicating its strong capacity to predict the target event. In contrast, the Gouveia system had an AUC of only 0.551 (95% CI: 0.395-0.708), approaching random prediction and lacking reliability. At a cut-off value of 0.427, the nomogram achieved 66.7% sensitivity, 96.1% specificity, 76.9% PPV, 93.7% NPV, and 91.3% accuracy—demonstrating a "high specificity priority" clinical advantage. Conversely, the Gouveia system had only 43.8% sensitivity and 31.8% PPV, with high risks of missed and incorrect diagnoses and 74.7% accuracy. The nomograms’ strong discriminative ability (AUC>0.8), balanced sensitivity, and high specificity make it more robust than traditional scoring systems, supporting its potential clinical utility for identifying 1-year chronic complications in pediatric ASA. We encountered several limitations when analyzing our results. First, the data came from a single-center retrospective analysis of Chinese patients with ASA, which may introduce information bias and limit generalizability. Second, the sample size was small, and there was a lack of external datasets for validation. Future research should use multi-center, large-sample clinical data to refine this prediction model. Conclusions In conclusion, the current prediction model shows promise in predicting the risk of chronic complications in children with ASA. It could guide clinical decisions, but more research is needed.

In developed countries, the incidence of pediatric ASA ranges from 1\u0026ndash;5 per 100,000 children [1]. Notably, ASA is a potentially destructive condition, with a high rate of severe and long-term complications in growing children [2]. Chronic complications associated with ASA include growth arrest, pathological fractures, avascular necrosis, joint stiffness, chronic dislocation, and joint deformities. Furthermore, infection recurrence may occur in cases of inadequate treatment or poor treatment compliance [3]. However, the variable clinical courses observed in pediatric patients have hindered the development of standardized management guidelines. Furthermore, in Asia, osteoarticular pathogens like Staphylococcus aureus show different characteristics compared to similar pathogens in the United States and Europe. This highlights the need for custom prediction models [4, 5].\u003c/p\u003e\u003cp\u003eMost existing studies on ASA have primarily relied on retrospective analyses to identify factors associated with chronic complications and disease prognosis [2,3,6\u0026ndash;8].

Normally distributed quantitative data were presented as mean (standard deviation), and non-normally distributed quantitative data as median (P25, P75). Categorical data were described by frequencies and proportions. For between-group comparisons, independent samples t-tests were used for normally distributed quantitative data, nonparametric tests for non-normally distributed data, and chi-square tests for categorical data. Missing values were handled via multiple imputation. Univariate analyses were conducted for all variables; statistically significant factors were included in a stepwise backward multiple logistic regression model. Using R software version 4.2.2 (R Core Team, Auckland, New Zealand), a nomogram for predicting childhood ASA chronic complications was developed based on identified independent predictors. The model was optimized by 1000 bootstrap iterations, and its predictive performance was internally validated via receiver operating characteristic (ROC) curves. The Hosmer-Lemeshow test evaluated the goodness-of-fit between predicted and observed outcomes, and calibration curves assessed calibration. Decision curve analysis quantified the nomogram's net benefit across threshold probabilities to validate its utility. A p-value\u0026thinsp;\u0026lt;\u0026thinsp;0.05 was considered statistically significant. The Gouveia scoring system was applied to predict cohort data risks, enabling direct performance comparison with the present study's nomogram.\u003c/p\u003e\u003c/div\u003e"},{"header":"Results","content":"\u003cp\u003eThis study enrolled 95 patients with ASA, including 51 males (53.7%) and 44 females (46.3%) (Fig.\u0026nbsp;\u003cspan refid=\"Fig1\" class=\"InternalRef\"\u003e1\u003c/span\u003e).

the Prognostic Nomogram\u003c/h3\u003e\n\u003cp\u003eInternal validation of the nomogram for predicting chronic complications in pediatric ASA patients was performed using bootstrap resampling with 1000 iterations. The area under the curve (AUC) was 0.882 (95% confidence interval [CI]: 0.786\u0026ndash;0.979), indicating high predictive accuracy (Fig.\u0026nbsp;\u003cspan refid=\"Fig3\" class=\"InternalRef\"\u003e3\u003c/span\u003e). The optimal cut-off value was determined to be 0.427, at which the sum of sensitivity and specificity reached the maximum: sensitivity was 66.7%, specificity was 96.1%, positive predictive value (PPV) was 76.9%, negative predictive value (NPV) was 93.7%, and overall accuracy was 91.3%. These results demonstrated good discriminative ability of the model (Table\u0026nbsp;4). The Hosmer-Lemeshow test yielded a p-value of 0.447, suggesting no significant deviation from perfect fit and confirming the model's satisfactory predictive accuracy. The calibration curve, which compared predicted outcomes with actual results, further verified the reliability of the model in the validation set (Fig.\u0026nbsp;\u003cspan refid=\"Fig4\" class=\"InternalRef\"\u003e4\u003c/span\u003e). Decision curve analysis (DCA) demonstrated the clinical utility of the model by showing its net benefit across the threshold probability range for predicting chronic complications in ASA patients (Fig.\u0026nbsp;\u003cspan refid=\"Fig5\" class=\"InternalRef\"\u003e5\u003c/span\u003e).\u003c/p\u003e\u003cp\u003e\u003c/p\u003e\u003cp\u003e\u003c/p\u003e\u003cp\u003e\u003c/p\u003e\u003cp\u003eA comparative study of the prediction model for chronic complications in pediatric ASA patients was conducted using the Gouveia et al. scoring system [9] (Table\u0026nbsp;4). When the Gouveia et al. scoring system was applied to predict the risk of chronic complications in the same patient cohort, the AUC was 0.551 (95% CI: 0.395\u0026ndash;0.708). At the cut-off value of 0.041, the system achieved a sensitivity of 43.8%, specificity of 81%, PPV of 31.8%, NPV of 87.7%, and overall accuracy of 74.7%.\u003c/p\u003e"},{"header":"Discussion","content":"\u003cp\u003eThis population-based study revealed that the following factors may be associated with chronic complications in the prognosis of pediatric ASA: WBC, SAA, HCT, HGB, MPV, ALT and AST on admission; SAA, HCT, HGB at discharge, bacteremia, staphylococcus aureus detection, bone abscess, delayed source control, bone debridement, isolated arthritis and arthritis combined dislocation or subluxation. Further multivariate analysis revealed that WBC on admission, ALT on admission, SAA at discharge, and arthritis combined with dislocation or subluxation were independent risk factors for chronic complications in these patients.\u003c/p\u003e\u003cp\u003eElevated WBC count is a hallmark of suppurative arthritis, reflecting bacterial load and inflammatory intensity [10,11]. Persistent leukocyte infiltration activates the complement system via enzymatic hydrolysis, cell death, and cytokine release; complement then amplifies inflammation through leukocyte chemotaxis and activation [12\u0026ndash;14], ultimately leading to inflammatory escalation and tissue damage.\u003c/p\u003e\u003cp\u003eDuring infection, the liver participates in the acute-phase response by synthesizing acute-phase proteins (e.g., SAA, CRP) to regulate systemic inflammation [15]. Concurrently, hepatocytes may be injured by inflammatory mediators (e.g., tumor necrosis factor-α, interleukin-6) [16\u0026ndash;18], forming an \"inflammation-hepatic damage\" vicious cycle that causes ALT release into the bloodstream. Elevated admission ALT may thus reflect both the magnitude of the host inflammatory response and liver involvement in inflammation. Notably, direct studies exploring the association between admission ALT and ASA prognostic risk remain limited, warranting confirmation in future prospective investigations.\u003c/p\u003e\u003cp\u003eSerum SAA levels rise precipitously following infection: during the acute-phase response to tissue injury, approximately 2.5-3% of hepatic protein synthesis is dedicated to SAA production, enabling plasma concentrations to increase from 1\u0026ndash;5 \u0026micro;g/mL to 1000 \u0026micro;g/mL within 24 hours [19,20]. This elevation persists for 2\u0026ndash;3 days (circulating SAA half-life\u0026thinsp;\u0026asymp;\u0026thinsp;90 minutes) and normalizes within 7\u0026ndash;10 days if tissue injury resolves [21,22]. A higher SAA level at discharge may therefore indicate unresolved inflammation and ongoing tissue damage.\u003c/p\u003e\u003cp\u003ePrevious studies have shown that acetabular dysplasia often persists during follow-up in children with ASA complicated by dislocation or subluxation, suggesting severe joint damage [23]. For instance, dislocation of the hip joint, which is a ball-and-socket joint characterized by an extensive range of motion and a thick articular capsule, can readily compress periarticular blood vessels, thereby leading to femoral head avascular necrosis [24,25].\u003c/p\u003e\u003cp\u003eCalculating chronic complication risk scores during hospitalization aids in determining optimal management strategies. Over 90% of patients who develop chronic complications do so within one year of admission, supporting the rationale for one-year follow-up in high-risk patients [3,26,27]. When elevated risk is predicted, orthopedic surgeons should recommend extended outpatient follow-up to closely monitor complication development and provide families with guidance on prevention strategies.\u003c/p\u003e\u003cp\u003eIn our ASA cohort, arthritis with dislocation emerged as a strong independent risk factor (B\u0026thinsp;=\u0026thinsp;3.337, χ\u0026sup2;=10.368, P\u0026thinsp;=\u0026thinsp;0.001), with an odds ratio (OR) of 28.134 (95% CI: 3.691-214.431), indicating a 28.134-fold higher risk of chronic complications compared to patients without dislocation. Three laboratory markers also showed significant positive associations: each 1-unit increase in admission WBC count was associated with a 16.5% increased risk (OR\u0026thinsp;=\u0026thinsp;1.165, 95% CI: 1.038\u0026ndash;1.308, P\u0026thinsp;=\u0026thinsp;0.009); each 1-unit increase in admission ALT with a 1.4% increased risk (OR\u0026thinsp;=\u0026thinsp;1.014, 95% CI: 1.004\u0026ndash;1.025, P\u0026thinsp;=\u0026thinsp;0.006); and each 1-unit increase in discharge SAA with a 15.3% increased risk (OR\u0026thinsp;=\u0026thinsp;1.153, 95% CI: 1.029\u0026ndash;1.292, P\u0026thinsp;=\u0026thinsp;0.014). These variables demonstrated good discriminative ability for predicting 1-year chronic complications.\u003c/p\u003e\u003cp\u003eGiven the accessibility of these risk variables, we compared our nomogram to the Gouveia scoring system. While the Gouveia system [9] has demonstrated satisfactory predictive performance within the local cohorts, our findings indicate that the nomogram exhibits superior discriminatory ability, particularly among Chinese patients. The nomogram\u0026apos;s AUC of 0.882 (95% CI: 0.786-0.979) significantly surpasses the moderate prediction level threshold of 0.7, indicating its strong capacity to predict the target event. In contrast, the Gouveia system had an AUC of only 0.551 (95% CI: 0.395-0.708), approaching random prediction and lacking reliability. At a cut-off value of 0.427, the nomogram achieved 66.7% sensitivity, 96.1% specificity, 76.9% PPV, 93.7% NPV, and 91.3% accuracy\u0026mdash;demonstrating a \u0026quot;high specificity priority\u0026quot; clinical advantage. Conversely, the Gouveia system had only 43.8% sensitivity and 31.8% PPV, with high risks of missed and incorrect diagnoses and 74.7% accuracy. The nomograms\u0026rsquo; strong discriminative ability (AUC\u0026gt;0.8), balanced sensitivity, and high specificity make it more robust than traditional scoring systems, supporting its potential clinical utility for identifying 1-year chronic complications in pediatric ASA.\u003c/p\u003e\n\u003cp\u003eWe encountered several limitations when analyzing our results. First, the data came from a single-center retrospective analysis of Chinese patients with ASA, which may introduce information bias and limit generalizability. Second, the sample size was small, and there was a lack of external datasets for validation. Future research should use multi-center, large-sample clinical data to refine this prediction model.\u003c/p\u003e"},{"header":"Conclusions","content":"\u003cp\u003eIn conclusion, the current prediction model shows promise in predicting the risk of chronic complications in children with ASA.

We sought to develop a risk prediction model to identify chronic complications in children with ASA.\u003c/p\u003e\u003ch2\u003eMethods\u003c/h2\u003e\u003cp\u003eThis retrospective observational study enrolled children (ages one month to 18 years) diagnosed with ASA who were hospitalized at a tertiary pediatric hospital between 2016 and 2023. We documented clinical management, complication status, and sequelae, and constructed a multivariate logistic regression model for predicting chronic complications.\u003c/p\u003e\u003ch2\u003eResults\u003c/h2\u003e\u003cp\u003eA total of 95 children were identified, 16.8% of whom experienced chronic complications from ASA over a 12-month follow-up period. Univariate logistic analysis identified the following factors associated with chronic complication development: white blood cell (WBC), serum amyloid A (SAA), hematocrit, hemoglobin, mean platelet volume, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) on admission; SAA, hematocrit (HCT), and hemoglobin (HGB) at discharge; bacteremia; Staphylococcus aureus detection; bone abscess; delayed source control; bone debridement; isolated arthritis; and arthritis combined with dislocation or subluxation (all p\u0026thinsp;\u0026lt;\u0026thinsp;0.05). On further multivariate logistic regression analysis, we identified four independent predictors: WBC on admission (OR\u0026thinsp;=\u0026thinsp;1.165, 95% CI: 1.038\u0026ndash;1.308), ALT on admission (OR\u0026thinsp;=\u0026thinsp;1.014, 95% CI: 1.004\u0026ndash;1.025), SAA at discharge (OR\u0026thinsp;=\u0026thinsp;1.153, 95% CI: 1.029\u0026ndash;1.292), and arthritis combined with dislocation or subluxation (OR\u0026thinsp;=\u0026thinsp;28.134, 95% CI: 3.691\u0026ndash;214.431). The area under the receiver operating characteristic (ROC) curve was 0.882 (95% CI: 0.786\u0026ndash;0.979). The logistic regression model formula was: Log(P) = -8.459\u0026thinsp;+\u0026thinsp;0.153\u0026times;WBC on admission\u0026thinsp;+\u0026thinsp;0.014\u0026times;ALT on admission\u0026thinsp;+\u0026thinsp;0.142\u0026times;SAA at discharge\u0026thinsp;+\u0026thinsp;3.337\u0026times;arthritis combined with dislocation or subluxation.\u003c/p\u003e\u003ch2\u003eConclusion\u003c/h2\u003e\u003cp\u003eThe prediction model for chronic complications of pediatric ASA incorporates four key variables: WBC on admission, ALT on admission, SAA at discharge, and arthritis combined with dislocation or subluxation.
