Methods: Adult non-pregnant hospitalized patients diagnosed with T2DM were retrospectively enrolled from the electronic medical record system of the Affiliated Hospital of Qingdao University. Patients were categorized into hypoglycemia groups (mild, moderate-to-severe) or a non-hypoglycemia group based on inpatient venous plasma glucose levels. After data preprocessing, univariate and multivariate analyses were conducted to identify significant predictors. Three predictive models (XGBoost, Random Forest [RF], and Logistic Regression) were subsequently constructed and validated to evaluate their predictive performances. Results: From an initial cohort of 8,947 patients, 1,798 patients were included after data screening. Among the evaluated models, the RF model demonstrated the highest predictive accuracy (93.3%) and Kappa coefficient (0.873), followed by XGBoost (accuracy: 92.6%, Kappa: 0.860). Logistic regression exhibited comparatively lower performance (accuracy: 83.8%, Kappa: 0.685). The macro-average area under the ROC curve (AUC) values for RF, XGBoost, and logistic regression were 0.960, 0.955, and 0.788, respectively, highlighting the superior discriminative capability of the RF model. While both XGBoost and RF models identified glycemic control metrics and glucose variability as core predictors for hypoglycemia, the RF model additionally emphasized medication usage, whereas XGBoost prioritized basal metabolic parameters. Conclusions: The RF model outperformed XGBoost and conventional logistic regression in predicting hypoglycemia severity among hospitalized T2DM patients. The results emphasize the importance of closely monitoring glucose levels and glucose variability during diabetes management to prevent hypoglycemia. The developed model provides a foundation for implementing preventive strategies to reduce hypoglycemia occurrence in hospitalized patients with T2DM. Health sciences/Diseases Health sciences/Endocrinology Health sciences/Medical research Type 2 diabetes mellitus Hypoglycemia Risk prediction Machine learning Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Introduction Diabetes mellitus (DM) is a major chronic disease worldwide, with prevalence rates steadily rising over recent decades [ 1 ] . Diabetes and its associated complications pose significant threats to patient health and quality of life, greatly impacting patients' daily activities and potentially leading to mortality in severe cases. Among these complications, hypoglycemia is particularly critical to prevent and manage due to its frequent occurrence and substantial health risks for diabetic patients [ 2 ] . Hypoglycemic events in diabetic patients are multifactorial, influenced by medications, diet, lifestyle, and comorbidities [ 3 – 5 ] . Recently, stringent glycemic control strategies have been associated with an increased risk of hypoglycemia. However, hypoglycemia can undermine the long-term benefits gained from good glycemic management, underscoring the importance of carefully balancing the benefits and risks of intensive glucose management. Hospitals play a central role in glycemic control, adjustments of antidiabetic medications, and individualized care for diabetic patients, placing heightened responsibilities on healthcare professionals. Patients with diabetes commonly exhibit multiple comorbidities that contribute independently to hypoglycemia risk. Studies have identified older age, renal impairment, liver dysfunction, poor nutritional status, inappropriate medication use, and debilitating diseases as critical risk factors for hypoglycemia. Clinical practitioners thus must analyze these risk factors systematically to accurately assess the probability of hypoglycemia and implement effective preventive measures. Predicting hypoglycemia accurately, however, remains challenging due to the complex interplay of various clinical and biological factors. Although multiple studies have confirmed insulin therapy [ 6 ] , impaired renal function, and suboptimal glycemic control as significant predictors of hypoglycemia, reliably forecasting such events remains difficult. Traditional logistic regression models have been widely employed to identify risk factors but are limited by their assumption of linear relationships between predictors and outcomes. With advancements in machine learning techniques, models such as Extreme Gradient Boosting (XGBoost) and Random Forest (RF) have shown remarkable performance in predicting complex clinical outcomes due to their ability to capture nonlinear interactions and handle high-dimensional data. Nevertheless, few studies have systematically compared traditional statistical methods and machine learning algorithms in predicting hypoglycemia severity among hospitalized patients with diabetes. Thus, the current study aimed to develop and compare three predictive models—multinomial logistic regression, XGBoost, and RF—to identify independent risk factors and predict the severity of hypoglycemia among hospitalized patients with type 2 diabetes mellitus (T2DM). Additionally, we performed a feature importance analysis to provide clinical insights into the most critical predictors associated with hypoglycemia risk. Our findings may facilitate early intervention strategies and enhance individualized patient management during hospitalization. Machine Learning Model Development Three predictive models were developed and evaluated: multinomial logistic regression, XGBoost, and Random Forest. Hyperparameters for the XGBoost and RF models were optimized using cross-validation. Multiclass ROC curves were constructed using a One-vs-Rest approach to visualize and compare the models' predictive capabilities. Methods Study Design and Population This retrospective study was conducted using data from the electronic medical record system of the Affiliated Hospital of Qingdao University. Initially, 8,947 adult, non-pregnant hospitalized patients with a confirmed diagnosis of T2DM were identified. After applying inclusion and exclusion criteria, a total of 1,798 patients were included in the final analysis. Data Collection Clinical and demographic data were extracted from electronic medical records, including demographic characteristics, clinical features, laboratory findings, and antidiabetic medication use. Variables collected were age, gender, body mass index (BMI) classification, Charlson Comorbidity Index (CCI), glycated hemoglobin (HbA1c), mean blood glucose levels, serum creatinine, C-peptide, lipid profile, and use of antidiabetic medications (e.g., insulin, metformin, DPP-4 inhibitors). Patient Grouping Patients were categorized into three groups based on venous plasma glucose levels measured during hospitalization: Normal glycemia: >3.9 mmol/L Mild hypoglycemia: 3.0–3.9 mmol/L Moderate-to-severe hypoglycemia: <3.0 mmol/L Statistical Analysis Univariate analyses were conducted using the chi-square test for categorical variables and the Kruskal-Wallis test for continuous variables. Variables with a P-value < 0.05 were entered into a multivariate multinomial logistic regression analysis. Model performance was evaluated using overall accuracy, Kappa statistic, the area under the receiver operating characteristic (ROC) curve (AUC), and confusion matrices. All statistical analyses were performed using R software and SPSS. Results Patient Characteristics A total of 1,798 hospitalized diabetic patients were included in the final analysis. Based on inpatient blood glucose measurements, patients were divided into three groups: normoglycemic, mild hypoglycemia, and moderate-to-severe hypoglycemia. Significant differences were observed among the three groups in age, Charlson Comorbidity Index (CCI), the number of glucose-lowering medication classes, triglycerides (TG), serum creatinine, glycated hemoglobin (HbA1c), C-peptide, mean glucose levels, cholesterol, gender distribution, BMI classification, and use of various glucose-lowering medications (including SGLT2 inhibitors, α-glucosidase inhibitors, metformin, thiazolidinediones, and insulin) (all P < 0.05). Baseline characteristics of the study population are detailed in Table 1 .

Specifically, an increased Charlson index, lower BMI, reduced C-peptide levels, decreased TG, elevated HbA1c, elevated creatinine levels, and insulin use were linked to a higher risk of hypoglycemia.

ROC curves for each model are illustrated individually in Fig. 1 ,Fig. 2 ,Fig. 3 , and a direct comparative analysis among the three models is presented in Fig. 4 . The multinomial logistic regression model yielded area under the curve (AUC) values of 0.938 for predicting normoglycemia, 0.889 for mild hypoglycemia, and 0.754 for moderate-to-severe hypoglycemia. The XGBoost model demonstrated notably higher AUCs of 0.991, 0.980, and 0.943, respectively. Similarly, the RF model achieved AUCs of 0.991, 0.983, and 0.952 for the three respective severity categories. Comparative ROC analysis (Fig. 4 ) clearly indicated superior discriminative performance of both XGBoost and RF models across all hypoglycemia severity categories compared to logistic regression. Model Performance Comparison To comprehensively evaluate predictive performances, we compared the overall accuracy, Kappa coefficient, and macro-average AUC of the three models (Table 4 ). The RF model achieved the highest accuracy (93.3%) and Kappa coefficient (0.873), followed closely by XGBoost (accuracy: 92.6%, Kappa: 0.860). Logistic regression demonstrated relatively lower performance, with an accuracy of 83.8% and Kappa of 0.685. Consistently, the macro-average AUC values for RF, XGBoost, and logistic regression were 0.960, 0.955, and 0.788, respectively, further emphasizing the superior predictive capability of the tree-based machine learning algorithms.

Subsequent important predictors in the XGBoost model included creatinine, C-peptide, and triglycerides (TG). In the RF model, following mean glucose and HbA1c, important predictors included C-peptide, insulin usage, and the Charlson comorbidity index. Discussion In the present study, we developed and systematically compared three predictive models—multinomial logistic regression, XGBoost, and random forest (RF)—to identify key predictors of hypoglycemia severity among hospitalized patients with diabetes. Our results demonstrated that both machine learning models (XGBoost and RF) exhibited superior discriminative performance compared to traditional logistic regression, especially for detecting moderate-to-severe hypoglycemia, this has some modeling studies with the same results [ 7 ] . We utilized the One-vs-Rest strategy, a standard and effective approach for generating ROC curves in multiclass classification problems, allowing robust evaluation and comparison of each model's predictive performance across hypoglycemia categories. The dataset used to construct our predictive models comprised common clinical and laboratory variables routinely available for hospitalized patients with type 2 diabetes mellitus (T2DM). The logistic regression model identified seven statistically significant predictors (P < 0.05), while both XGBoost and RF models highlighted the top 10 most influential variables. Notably, six predictors—age, Charlson Comorbidity Index (CCI), serum creatinine, HbA1c, mean glucose levels, and insulin use—emerged consistently as significant factors across all three models. A number of previous modeling studies and factor analysis studies have similarly given the same conclusions for one or more of these factors [ 8 – 10 ] . While previous studies have individually confirmed the significance of one or several of these factors, our research uniquely integrated multiple models for comprehensive comparison, offering a broader perspective than single-model studies previously reported. A key advantage of our study lies in its reliance on routinely collected clinical data. This facilitates rapid assessment of hypoglycemia risk without additional specialized testing, thus granting medical staff valuable time to implement preventive strategies and appropriate treatments. Regarding predictive variables, HbA1c has consistently been identified as a crucial factor in hypoglycemia research. Prior studies have reported that both excessively high HbA1c levels (> 9%) and overly stringent glycemic control (HbA1c < 7%) are associated with increased hypoglycemia risk [ 11 ] . Additionally, insulin use within these HbA1c ranges further exacerbates hypoglycemia risk. Both our univariate and multivariate analyses supported these findings, reinforcing that elevated HbA1c levels and insulin therapy are critical risk factors for hypoglycemia in diabetic patients. In recent years, growing attention has focused on the association between the Charlson Comorbidity Index (CCI) and hypoglycemia. Most prior studies investigating comorbidities typically examined only one or a few components of the CCI, such as cardiovascular disease, renal impairment, or malignancy [ 12 ] . These comorbid conditions have been associated with glucose instability and heightened risk of adverse glycemic events. Patients with multiple chronic diseases often experience altered drug metabolism, polypharmacy, and malnutrition, potentially interfering with glucose regulation and insulin sensitivity. Incorporating the CCI into all three predictive models in our study enhances its utility as a comprehensive clinical indicator. Unlike individual diagnoses, the CCI provides an aggregated measure of overall disease burden, capturing complex interactions between comorbidities and thereby improving the generalizability and interpretability of the predictive models. Integrating the CCI into predictive assessments may assist clinicians in accurately stratifying risk, particularly among elderly hospitalized patients or those with multiple chronic diseases, who inherently have higher susceptibility to hypoglycemic episodes [ 13 ] . Early identification of high-CCI patients could facilitate personalized monitoring, medication adjustments, and tailored nutritional plans, thereby mitigating hypoglycemia risk. Lastly, we conducted feature importance analyses for the top ten variables in the XGBoost and RF models. Both models consistently identified glycemic control and glucose variability as key predictors. Additionally, XGBoost emphasized basal metabolic parameters (e.g., creatinine and C-peptide), whereas the RF model placed greater emphasis on medication use. These findings highlight nuanced differences between machine learning approaches, underscoring their ability to provide targeted clinical insights into managing and preventing hypoglycemic events in hospitalized diabetic patients. Conclusions In this study, we developed and compared three prediction models - multinomial logistic regression, XGBoost, and random forest - to identify factors associated with hypoglycemia severity in hospitalized diabetic patients. Our results showed that both machine learning models outperformed the traditional logistic regression model in terms of predictive performance, with higher accuracy and AUC values in all hypoglycemia categories. This time, the three models were designed with all commonly used clinical indicators, without the need for special tests, to prevent hypoglycemia as early as possible in type 2 diabetic patients and to avoid the adverse consequences caused by hypoglycemia. In a comparison of the three models and the focus of the models, the six variables of age, Charlson comorbidity index, creatinine, glycosylated hemoglobin, mean blood glucose level, and insulin use were consistently identified as core predictors in almost all models [ 14 – 16 ] , This further enhances their clinical relevance。Future studies should focus on the prospective validation and practical application of these models to assess their clinical utility and impact on patient safety. Limitations The model was designed to use only common clinical indicators, and because hypoglycaemia occurs in a variety of ways, even if the model had a higher degree of accuracy, it would still not be able to fully diagnose all types of hypoglycaemia. As this study was based on single-centre data, further validation of the predictive effect of the model is needed in the future.

Diabetes and its associated complications pose significant threats to patient health and quality of life, greatly impacting patients' daily activities and potentially leading to mortality in severe cases. Among these complications, hypoglycemia is particularly critical to prevent and manage due to its frequent occurrence and substantial health risks for diabetic patients \u003csup\u003e[\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e]\u003c/sup\u003e. Hypoglycemic events in diabetic patients are multifactorial, influenced by medications, diet, lifestyle, and comorbidities \u003csup\u003e[\u003cspan additionalcitationids=\"CR4\" citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e–\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e]\u003c/sup\u003e. Recently, stringent glycemic control strategies have been associated with an increased risk of hypoglycemia. However, hypoglycemia can undermine the long-term benefits gained from good glycemic management, underscoring the importance of carefully balancing the benefits and risks of intensive glucose management.\u003c/p\u003e \u003cp\u003eHospitals play a central role in glycemic control, adjustments of antidiabetic medications, and individualized care for diabetic patients, placing heightened responsibilities on healthcare professionals. Patients with diabetes commonly exhibit multiple comorbidities that contribute independently to hypoglycemia risk. Studies have identified older age, renal impairment, liver dysfunction, poor nutritional status, inappropriate medication use, and debilitating diseases as critical risk factors for hypoglycemia. Clinical practitioners thus must analyze these risk factors systematically to accurately assess the probability of hypoglycemia and implement effective preventive measures.\u003c/p\u003e \u003cp\u003ePredicting hypoglycemia accurately, however, remains challenging due to the complex interplay of various clinical and biological factors. Although multiple studies have confirmed insulin therapy\u003csup\u003e[\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e]\u003c/sup\u003e, impaired renal function, and suboptimal glycemic control as significant predictors of hypoglycemia, reliably forecasting such events remains difficult. Traditional logistic regression models have been widely employed to identify risk factors but are limited by their assumption of linear relationships between predictors and outcomes.\u003c/p\u003e \u003cp\u003eWith advancements in machine learning techniques, models such as Extreme Gradient Boosting (XGBoost) and Random Forest (RF) have shown remarkable performance in predicting complex clinical outcomes due to their ability to capture nonlinear interactions and handle high-dimensional data. Nevertheless, few studies have systematically compared traditional statistical methods and machine learning algorithms in predicting hypoglycemia severity among hospitalized patients with diabetes.\u003c/p\u003e \u003cp\u003eThus, the current study aimed to develop and compare three predictive models—multinomial logistic regression, XGBoost, and RF—to identify independent risk factors and predict the severity of hypoglycemia among hospitalized patients with type 2 diabetes mellitus (T2DM). Additionally, we performed a feature importance analysis to provide clinical insights into the most critical predictors associated with hypoglycemia risk.

Our results demonstrated that both machine learning models (XGBoost and RF) exhibited superior discriminative performance compared to traditional logistic regression, especially for detecting moderate-to-severe hypoglycemia, this has some modeling studies with the same results\u003csup\u003e[\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e]\u003c/sup\u003e.

The logistic regression model identified seven statistically significant predictors (P\u0026thinsp;\u0026lt;\u0026thinsp;0.05), while both XGBoost and RF models highlighted the top 10 most influential variables. Notably, six predictors\u0026mdash;age, Charlson Comorbidity Index (CCI), serum creatinine, HbA1c, mean glucose levels, and insulin use\u0026mdash;emerged consistently as significant factors across all three models. A number of previous modeling studies and factor analysis studies have similarly given the same conclusions for one or more of these factors\u003csup\u003e[\u003cspan additionalcitationids=\"CR9\" citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e\u0026ndash;\u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e]\u003c/sup\u003e. While previous studies have individually confirmed the significance of one or several of these factors, our research uniquely integrated multiple models for comprehensive comparison, offering a broader perspective than single-model studies previously reported.\u003c/p\u003e \u003cp\u003eA key advantage of our study lies in its reliance on routinely collected clinical data. This facilitates rapid assessment of hypoglycemia risk without additional specialized testing, thus granting medical staff valuable time to implement preventive strategies and appropriate treatments.\u003c/p\u003e \u003cp\u003eRegarding predictive variables, HbA1c has consistently been identified as a crucial factor in hypoglycemia research. Prior studies have reported that both excessively high HbA1c levels (\u0026gt;\u0026thinsp;9%) and overly stringent glycemic control (HbA1c\u0026thinsp;\u0026lt;\u0026thinsp;7%) are associated with increased hypoglycemia risk\u003csup\u003e[\u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e]\u003c/sup\u003e. Additionally, insulin use within these HbA1c ranges further exacerbates hypoglycemia risk. Both our univariate and multivariate analyses supported these findings, reinforcing that elevated HbA1c levels and insulin therapy are critical risk factors for hypoglycemia in diabetic patients.\u003c/p\u003e \u003cp\u003eIn recent years, growing attention has focused on the association between the Charlson Comorbidity Index (CCI) and hypoglycemia. Most prior studies investigating comorbidities typically examined only one or a few components of the CCI, such as cardiovascular disease, renal impairment, or malignancy\u003csup\u003e[\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e]\u003c/sup\u003e. These comorbid conditions have been associated with glucose instability and heightened risk of adverse glycemic events. Patients with multiple chronic diseases often experience altered drug metabolism, polypharmacy, and malnutrition, potentially interfering with glucose regulation and insulin sensitivity. Incorporating the CCI into all three predictive models in our study enhances its utility as a comprehensive clinical indicator. Unlike individual diagnoses, the CCI provides an aggregated measure of overall disease burden, capturing complex interactions between comorbidities and thereby improving the generalizability and interpretability of the predictive models. Integrating the CCI into predictive assessments may assist clinicians in accurately stratifying risk, particularly among elderly hospitalized patients or those with multiple chronic diseases, who inherently have higher susceptibility to hypoglycemic episodes\u003csup\u003e[\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e]\u003c/sup\u003e. Early identification of high-CCI patients could facilitate personalized monitoring, medication adjustments, and tailored nutritional plans, thereby mitigating hypoglycemia risk.\u003c/p\u003e \u003cp\u003eLastly, we conducted feature importance analyses for the top ten variables in the XGBoost and RF models. Both models consistently identified glycemic control and glucose variability as key predictors. Additionally, XGBoost emphasized basal metabolic parameters (e.g., creatinine and C-peptide), whereas the RF model placed greater emphasis on medication use. These findings highlight nuanced differences between machine learning approaches, underscoring their ability to provide targeted clinical insights into managing and preventing hypoglycemic events in hospitalized diabetic patients.\u003c/p\u003e"},{"header":"Conclusions","content":"\u003cp\u003eIn this study, we developed and compared three prediction models - multinomial logistic regression, XGBoost, and random forest - to identify factors associated with hypoglycemia severity in hospitalized diabetic patients.

While both XGBoost and RF models identified glycemic control metrics and glucose variability as core predictors for hypoglycemia, the RF model additionally emphasized medication usage, whereas XGBoost prioritized basal metabolic parameters.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eConclusions: \u003c/strong\u003eThe RF model outperformed XGBoost and conventional logistic regression in predicting hypoglycemia severity among hospitalized T2DM patients. The results emphasize the importance of closely monitoring glucose levels and glucose variability during diabetes management to prevent hypoglycemia. The developed model provides a foundation for implementing preventive strategies to reduce hypoglycemia occurrence in hospitalized patients with T2DM.\u003c/p\u003e","manuscriptTitle":"Machine Learning-Based Prediction of Hypoglycemia Severity in Hospitalized Diabetic Patients","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2025-05-16 12:18:54","doi":"10.21203/rs.3.rs-6619286/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"56439e66-d1ba-49a4-a3c9-b4c3c1ce6f74","owner":[],"postedDate":"May 16th, 2025","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[{"id":48247417,"name":"Health sciences/Diseases"},{"id":48247418,"name":"Health sciences/Endocrinology"},{"id":48247419,"name":"Health sciences/Medical research"}],"tags":[],"updatedAt":"2025-05-23T10:38:40+00:00","versionOfRecord":[],"versionCreatedAt":"2025-05-16 12:18:54","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-6619286","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-6619286","identity":"rs-6619286","version":["v1"]},"buildId":"8U1c8b4HqxoKbykW_rLl7","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
