Methods A total of 507 stoma patients who visited the Department of General Surgery (Colorectal Surgery), Oncology Department and Wound Stoma Clinic of a tertiary Grade A hospital in Jinzhou City from March 2025 to January 2026 were selected as the research subjects by convenient sampling. The data were randomly divided into a training set and a validation set at a ratio of 7:3. LASSO algorithm and Logistic regression analysis were combined to screen the risk factors. Five machine learning algorithms, namely Logistic Regression (LR), Support Vector Machine (SVM), Naive Bayes, K-Nearest Neighbor (KNN) and Decision Tree, were used to construct the prediction models for social isolation in stoma patients. The area under the receiver operating characteristic (ROC) curve (AUC), accuracy, sensitivity, specificity, precision and F1 score were used to evaluate and compare the predictive performance of the models. Finally, the optimal risk prediction model with the best predictability and practicability was selected for SHapley Additive exPlanations (SHAP) analysis to demonstrate the importance of predictive factors. Results Among the 507 patients with colorectal cancer after stoma surgery, 163 cases suffered from social isolation, with an incidence rate of 32.3%. Among the five machine learning models, the LR model showed the best performance, with an AUC of 0.813 (95%CI: 0.746–0.882), a sensitivity of 0.544, an accuracy of 0.724, a precision of 0.660, a specificity of 0.832 and an F1 score of 0.596. The SHAP bar chart showed that the top four influencing factors were gender, place of residence, social support and psychological vulnerability. Conclusion The LR model has the best performance in predicting the risk of social isolation in patients with colorectal cancer after stoma surgery, which can provide a screening tool for clinical workers to conduct early identification of high-risk groups.

With the rapid development of China's social economy and the remarkable improvement of residents' living standards, profound changes have taken place in people's dietary structure and lifestyle, and the incidence and mortality rates of colorectal cancer have also shown a continuous upward trend [2] . Studies have shown that approximately 20% to 30% of patients with low rectal cancer require permanent enterostomy [3] . Although enterostomy can save patients' lives, it may cause physical discomfort, negative emotions, social avoidance and other problems [4] , which in turn leads to social isolation and seriously impairs patients' quality of life and the recovery of their social functions [5] . Social isolation is defined as a phenomenon where individuals experience neglect or rejection from others during social interactions, find it difficult to establish or maintain normal social connections, thus triggering a series of negative emotions, and ultimately exhibiting passive behaviors such as apathy, avoidance and refusal [6] . Prolonged social isolation can result in patients' self-seclusion, exacerbate psychological distress, and may reduce the body's anti-tumor immunity, increase the risk of tumor recurrence and metastasis, thereby threatening patients' survival and prognosis [7] . Relevant studies have indicated that the incidence of social isolation among cancer survivors is approximately 38% to 59% [8] . In view of this, early identification of the risk factors for social isolation in patients with colorectal cancer after stoma surgery and the implementation of targeted interventions are of great significance for reducing the incidence of social isolation. Commonly used clinical assessment tools can conduct preliminary screening for social isolation, yet their predictive ability for this condition still has certain limitations. As an artificial intelligence-driven health technology, machine learning has been widely applied in clinical practice, demonstrating significant advantages in disease prediction and diagnosis, effectively improving the accuracy and reliability of predictions [9] , and thus can provide a more precise method for social isolation risk assessment. Based on machine learning algorithms, this study constructed a risk prediction model for social isolation in patients with colorectal cancer after stoma surgery and compared the performance of different models. The Shapley Additive Explanation (SHAP) [10] algorithm was adopted to analyze the effect size relationship between each variable and the outcome variable, aiming to provide a scientific basis and practical reference for medical staff to early identify high-risk patients with social isolation and promptly implement individualized intervention strategies. Subjects and Methods 1.1 Research Subjects A total of 507 stoma patients who visited the Department of General Surgery (Colorectal Surgery), Oncology Department and Wound Stoma Clinic of a tertiary Grade A hospital in Jinzhou City from March 2025 to January 2026 were selected as the research subjects by convenient sampling. Inclusion criteria: (1) Colorectal cancer was diagnosed in accordance with the Chinese Clinical Practice Guidelines for Colorectal Cancer (2020 Edition) issued by the Oncology Branch of Chinese Medical Association and the Medical Administration and Medical Quality Control Bureau of the National Health Commission of the People's Republic of China [11] ; (2) Aged ≥ 18 years old; (3) Capable of normal communication, informed of the disease diagnosis, and voluntarily participating in this study. Exclusion criteria: (1) Suffering from mental diseases or cognitive dysfunction; (2) Tumor recurrence, metastasis or other malignant tumors; (3) With severe organ complications. The sample size of the model was calculated according to the Events per Variable (EPV) [12] , with the formula: N=p×EPV÷incidence rate of events. In the formula, p is the number of predictive variables, EPV is the number of events required for each variable, and the incidence rate of events is the probability of event occurrence in each sample. This study estimated that about 22 research variables would be included in the model. Combined with literature data, the incidence of social isolation in cancer survivors is about 38% to 59% [8] . According to the 1/10 rule, EPV was set to 10, and 10% invalid samples were considered at the same time. Therefore, the required sample size of this study was 22×10÷49%×(1+10%)≈494 cases, and the final sample size was 507 cases. 1.2 Investigation Tools Based on literature review, a questionnaire on risk factors for social isolation in patients with colorectal cancer after stoma surgery was self-designed through expert consultation and discussion of the research group. The investigation tools included the following parts: 1.2.1 General information: Gender, age, main caregiver, marital status, educational level, place of residence, living status, personality type, per capita family income, occupational status, type of medical insurance, complicated chronic diseases, clinical tumor stage (Stage Ⅰ, Ⅱ, Ⅲ, Ⅳ), time of tumor diagnosis, stoma status, time after stoma surgery, presence of stoma complications, and self-care status of stoma. 1.2.2 General Alienation Scale (GAS): The Chinese version revised by Wu et al [13] was used to measure the social isolation status of individuals. The scale includes 4 dimensions and 15 items, with a total score of 15 to 60 points (a higher score indicates a higher degree of social isolation). The Cronbach's α coefficient of this scale in this study was 0.749. With reference to previous literature, the median total score of 37.5 points was used as the boundary to divide alienation into high and low levels [14] . 1.2.3 Social Impact Scale (SIS): Compiled by Fife et al [15] and revised into Chinese by Pan et al [16] , it is used to measure the stigma of patients with chronic diseases such as cancer. The Chinese version includes 4 dimensions and 24 items, with a total score of 24 to 96 points (a higher score indicates a greater perceived social impact, i.e., a more serious stigma). The Cronbach's α coefficient of this scale in this study was 0.944. 1.2.4 Perceived Social Support Scale (PSSS): Compiled by Zimet et al [17] and translated and revised into Chinese by Jiang [18] . The scale includes 12 items and 3 dimensions, with a total score of 12 to 84 points (a higher score indicates a higher level of overall perceived social support). The total score was divided into three states: low support (12-36 points), moderate support (37-60 points) and high support (61-84 points). The Cronbach's α coefficient of this scale in this study was 0.903. 1.2.5 Mental Vulnerability Questionnaire (MVQ): Compiled by Eplov et al [19] and revised into Chinese by Gong et al [20] to evaluate the degree of psychological vulnerability of individuals. The scale includes 3 dimensions and 22 items, with a total score of 22 to 110 points (a higher score indicates a higher level of psychological vulnerability). The Cronbach's α coefficient of this scale in this study was 0.941. 1.2.6 Stoma Acceptance Questionnaire (SAQ): Compiled by Bagnasco et al [21] and translated into Chinese by Hu et al [22] . The questionnaire includes 3 dimensions and 12 items (4 items for evaluating importance), with a total score of 12 to 48 points (a higher score indicates a higher degree of stoma acceptance). The Cronbach's α coefficient of this scale in this study was 0.889. 1.3 Data Collection Method After literature review, the variables included in the study were finally determined through expert consultation and repeated discussion of the research group. Before data collection, the variable definitions were clarified and the researchers participating in data collection received unified standardized training (including research purpose, investigation requirements, data collection and entry specifications, etc.). The researchers were familiar with the evaluation content and key points of scale scoring, and strictly followed the inclusion and exclusion criteria to ensure the accuracy and credibility of data collection. Before data entry, all data were checked, and the data with abnormal values were verified by reviewing electronic medical records. Two researchers input the data respectively, checked each other, identified unreasonable questionnaires, and supplemented or deleted them in a timely manner to ensure the authenticity and accuracy of the data. Missing data were imputed in a timely manner according to the scope of missing to improve the accuracy of data analysis. 1.4 Model Development and Validation The data were randomly divided into a training set (355 cases) and a validation set (152 cases) at a ratio of 7:3. The training set was used for model training, and the validation set was used for model selection and evaluation. The characteristic variables screened by LASSO and multivariate Logistic regression were included in five algorithms (LR, SVM, Naive Bayes, KNN, Decision Tree) to construct prediction models, which were verified on the validation set. The predictive efficiency of the models was evaluated by the area under the ROC curve (AUC), accuracy, precision, sensitivity, specificity and F1 score. The Hosmer-Lemeshow goodness-of-fit test and calibration curve were used to evaluate the model calibration. The SHAP algorithm was used to analyze the influence degree and action mechanism of each characteristic variable on the optimal prediction model. 1.5 Statistical Analysis SPSS 25.0 and R 4.5.1 software were used for data analysis. The original data set was randomly divided into a training set and a validation set at a ratio of 7:3. The normal distribution of continuous variables was analyzed by the Kolmogorov-Smirnov test. Measurement data conforming to normal distribution were expressed as mean ± standard deviation ( s), and inter-group comparison was conducted by the t-test. Measurement data not conforming to normal distribution were described by median and interquartile range M[(P25,P75)], and inter-group comparison was conducted by the Mann-Whitney U test. Qualitative data were described by percentage ( % ), and inter-group comparison was conducted by the chi-square test. A two-sided P<0.05 was considered statistically significant. Results 2.1 Comparison of Baseline Data between Training Set and Validation Set A total of 507 samples were randomly divided into a training set (n = 355) and a validation set (n = 152). There were 142 cases (40.1%) of stoma patients with social isolation in the training set and 57 cases (37.7%) in the validation set. The social isolation variable and other baseline variables in the two groups were balanced and comparable (P > 0.05). See Table 1 for details.

Considering the simplicity, robustness and overfitting risk of the model, lambda.1se was selected as the final screening criterion, and 8 variables were screened out: gender, place of residence, stoma status, presence of stoma complications, stigma, social support, psychological vulnerability and stoma acceptance. 2.4 Multivariate Logistic Regression Analysis of Social Isolation Taking whether patients with colorectal cancer after stoma surgery suffered from social isolation as the dependent variable, and the 8 factors screened by LASSO regression as the independent variables (specific assignment see Table 3 ), multivariate Logistic regression analysis was performed. The results showed that gender, place of residence, stoma status, presence of stoma complications, stigma, social support, psychological vulnerability and stoma acceptance were all independent risk factors for social isolation in patients with colorectal cancer after stoma surgery (P < 0.05).

Five machine learning algorithms were used to construct prediction models, which were verified on the validation set. The results showed that the LR model had the best overall performance, with an AUC of 0.813 (95%CI: 0.746–0.882) in the validation set, and the sensitivity and F1 score were both higher than those of other models. The χ² of the Hosmer-Lemeshow test was 4.815 with a P value of 0.777, indicating that there was no significant difference between the predicted value of the model and the actual incidence rate. The performance evaluation of each model is shown in Table 5 . The ROC curves and calibration curves of the training set and the validation set were drawn respectively, which directly showed that the LR model had the best performance (Fig. 3 , Fig. 4 , Fig. 5 ).

The SHAP importance ranking (Fig. 6 ) showed that the top 4 variables affecting the occurrence of social isolation were gender, place of residence, social support and psychological vulnerability in turn. The SHAP value distribution showed the positive and negative relationships between each predictive variable and social isolation (Fig. 7 ): patients who were female, lived in rural areas, had low social support level and high psychological vulnerability had positive SHAP values (red dots), suggesting that these characteristics could significantly increase the risk of social isolation; while patients who were male, lived in urban areas, had high social support and stable psychological state had negative SHAP values (blue dots), suggesting that these characteristics could reduce the risk of social isolation. Discussion 3.1 Incidence of Social Isolation in Patients with Colorectal Cancer after Stoma Surgery This study included 507 patients with colorectal cancer after stoma surgery, and the incidence of social isolation was 32.3%, which was slightly higher than the research result of Yang [23] . This difference may be due to the fact that the subjects in this study were stoma patients after colorectal cancer surgery, and the changes in body image, defecation mode and stigma caused by stoma are more likely to lead to social isolation [24] . In addition, differences in sample sources, evaluation time points and sample sizes between the two studies may also be important reasons for the inconsistent results. In conclusion, the incidence of social isolation in patients with colorectal cancer after stoma surgery is at a moderate level. Clinical workers should pay close attention to the psychological and social adaptation of such patients, predict the occurrence of social isolation as early as possible and take targeted intervention measures, so as to reduce the risk of social isolation and improve the quality of life of patients. 3.2 Influencing Factors of Social Isolation in Patients with Colorectal Cancer after Stoma Surgery Multivariate Logistic regression analysis identified 8 independent risk factors for social isolation in patients with colorectal cancer after stoma surgery: gender, place of residence, stoma status, presence of stoma complications, stigma, social support, psychological vulnerability and stoma acceptance. The relevant discussion is as follows: Gender Female patients had a higher risk of social isolation, which was consistent with the research results of Zhang et al [25] . The reason may be that female patients pay more attention to self-image and physical integrity, and the physical changes after stoma surgery are easy to cause body image disturbance and reduced self-worth. In addition, females are more delicate and sensitive in emotional perception, and their unmet demand for social support and emotional companionship is more likely to lead to psychological gap and social avoidance [26] . Place of residence Rural patients had a higher risk of social isolation. The insufficient medical resources and imperfect rehabilitation support system in rural areas make it difficult for patients to obtain continuous stoma nursing guidance and psychological support after discharge [27] . At the same time, limited by educational level and health literacy [28] , rural patients have a low level of disease cognition, which is easy to cause disease uncertainty and further aggravate social isolation. Stoma status Patients with permanent stoma had a higher risk of social isolation than those with temporary stoma, which was consistent with the research of Wang et al [29] . Temporary stoma has a clear expectation of stoma reversal, and the physical changes are transient, so the psychological pressure of patients is light and social avoidance behavior is less [30] . However, permanent stoma leads to irreversible changes in physical function and image, making patients bear long-term care burden and stigma, and thus more prone to social isolation. Stoma complications Patients with stoma complications had a higher risk of social isolation. Relevant studies have shown that stoma complications are closely related to the decline of patients' quality of life and social participation [31,32] . Stoma complications not only increase the physical discomfort and self-care burden of patients [33] , but also limit their physical activity ability, affect normal social interaction, and ultimately further increase the risk of social isolation [34] . Stigma Stigma is an important psychological factor leading to social isolation. A qualitative study showed that the physical image changes caused by stoma make patients produce a strong sense of stigma and self-denial, and patients often reduce going out and avoid interpersonal interaction to avoid being discriminated against, thus showing social withdrawal behavior [35,36] . Social support As a key protective factor, high social support can effectively reduce the risk of social isolation in stoma patients. Social support can improve patients' ability to cope with diseases, alleviate negative emotions, reduce the sense of stigma, and thus promote patients' social participation and reduce social avoidance behavior. Psychological vulnerability Patients with high psychological vulnerability have weaker emotional regulation ability and psychological endurance [37] . They are more sensitive to the negative impacts of stoma (such as peculiar smell, leakage, body image changes) and external evaluations, and are easy to produce frustration and stigma, thus reducing social interaction and leading to social isolation. Stoma acceptance Patients with low stoma acceptance are more likely to suffer from social isolation. According to psychological theories, patients with high stoma acceptance can calmly accept physical changes and reduce negative emotions through positive cognitive restructuring, thus maintaining active social communication [38] ; while patients with low acceptance are accompanied by strong self-denial and tend to adopt social avoidance, which leads to social isolation. 3.3 Performance and Application Value of the Prediction Model Based on the 8 independent risk factors, this study constructed 5 machine learning prediction models for social isolation in stoma patients after colorectal cancer surgery. The results showed that the LR model had the optimal overall predictive efficiency, with an AUC of 0.813 (95%CI: 0.746–0.882) in the validation set. The calibration curve and Hosmer-Lemeshow test showed that the model had a good goodness of fit, and the predicted value was highly consistent with the actual incidence rate. Therefore, the LR model can be used as the optimal model for predicting the risk of social isolation in such patients. SHAP algorithm was used to further interpret the LR model, and the results showed that gender, place of residence, social support and psychological vulnerability were the top 4 core influencing factors. This result provides a clear direction for clinical intervention: clinical workers should focus on high-risk groups (female, rural residents, low social support, high psychological vulnerability), construct a three-dimensional support system of "medical staff-family-patients", carry out regular psychological assessment and counseling, and reduce the negative emotions caused by stoma. At the same time, medical staff can hold regular stoma patient fellowship meetings and build online communication groups to promote positive communication among patients, reduce the sense of loneliness and thus lower the level of social isolation [39] . Conclusion This study included 22 alternative variables, and 8 important risk factors for social isolation in patients with colorectal cancer after stoma surgery were screened by LASSO and Logistic regression analysis. Five machine learning prediction models were constructed with these factors, and the results showed that the LR model had the best predictive performance, which can be used as a reliable screening tool for clinical workers to early identify the high-risk groups of social isolation.SHAP analysis revealed that gender, place of residence, social support and psychological vulnerability were the top 4 core influencing factors, which provided a scientific basis for formulating targeted clinical intervention strategies. Clinical workers can take targeted intervention measures for high-risk groups to reduce the incidence of social isolation and improve the quality of life of patients. Limitations : This study is a cross-sectional study, which cannot track the dynamic development of social isolation in patients with colorectal cancer after stoma surgery. In addition, the samples were collected from a single tertiary hospital, and the sample representativeness is limited without external validation. In the follow-up study, the constructed model will be applied to stoma patients in other medical institutions and communities, and more external validation data will be collected to improve the generalization ability of the model. At the same time, a longitudinal study will be carried out to explore the dynamic change trajectory of social isolation in stoma patients and its influencing factors, so as to provide a more comprehensive basis for clinical intervention.

epithelium of the colon or rectum\u003csup\u003e\u0026nbsp;[1]\u003c/sup\u003e. With the rapid development of China\u0026apos;s social economy and the remarkable improvement of residents\u0026apos; living standards, profound changes have taken place in people\u0026apos;s dietary structure and lifestyle, and the incidence and mortality rates of colorectal cancer have also shown a continuous upward trend \u003csup\u003e[2]\u003c/sup\u003e. Studies have shown that approximately 20% to 30% of patients with low rectal cancer require permanent enterostomy\u003csup\u003e\u0026nbsp;[3]\u003c/sup\u003e. Although enterostomy can save patients\u0026apos; lives, it may cause physical discomfort, negative emotions, social avoidance and other problems\u003csup\u003e\u0026nbsp;[4]\u003c/sup\u003e, which in turn leads to social isolation and seriously impairs patients\u0026apos; quality of life and the recovery of their social functions\u003csup\u003e[5]\u003c/sup\u003e. Social isolation is defined as a phenomenon where individuals experience neglect or rejection from others during social interactions, find it difficult to establish or maintain normal social connections, thus triggering a series of negative emotions, and ultimately exhibiting passive behaviors such as apathy, avoidance and refusal\u003csup\u003e[6]\u003c/sup\u003e. Prolonged social isolation can result in patients\u0026apos; self-seclusion, exacerbate psychological distress, and may reduce the body\u0026apos;s anti-tumor immunity, increase the risk of tumor recurrence and metastasis, thereby threatening patients\u0026apos; survival and prognosis\u003csup\u003e\u0026nbsp;[7]\u003c/sup\u003e. Relevant studies have indicated that the incidence of social isolation among cancer survivors is approximately 38% to 59% \u003csup\u003e[8]\u003c/sup\u003e. In view of this, early identification of the risk factors for social isolation in patients with colorectal cancer after stoma surgery and the implementation of targeted interventions are of great significance for reducing the incidence of social isolation. Commonly used clinical assessment tools can conduct preliminary screening for social isolation, yet their predictive ability for this condition still has certain limitations. As an artificial intelligence-driven health technology, machine learning has been widely applied in clinical practice, demonstrating significant advantages in disease prediction and diagnosis, effectively improving the accuracy and reliability of predictions\u003csup\u003e\u0026nbsp;[9]\u003c/sup\u003e, and thus can provide a more precise method for social isolation risk assessment. Based on machine learning algorithms, this study constructed a risk prediction model for social isolation in patients with colorectal cancer after stoma surgery and compared the performance of different models.

This difference may be due to the fact that the subjects in this study were stoma patients after colorectal cancer surgery, and the changes in body image, defecation mode and stigma caused by stoma are more likely to lead to social isolation \u003csup\u003e[24]\u003c/sup\u003e.

The reason may be that female patients pay more attention to self-image and physical integrity, and the physical changes after stoma surgery are easy to cause body image disturbance and reduced self-worth. In addition, females are more delicate and sensitive in emotional perception, and their unmet demand for social support and emotional companionship is more likely to lead to psychological gap and social avoidance \u003csup\u003e[26]\u003c/sup\u003e.\u003c/p\u003e \u003c/p\u003e \u003cp\u003e \u003cstrong\u003ePlace of residence\u003c/strong\u003e \u003cp\u003eRural patients had a higher risk of social isolation. The insufficient medical resources and imperfect rehabilitation support system in rural areas make it difficult for patients to obtain continuous stoma nursing guidance and psychological support after discharge \u003csup\u003e[27]\u003c/sup\u003e. At the same time, limited by educational level and health literacy \u003csup\u003e[28]\u003c/sup\u003e, rural patients have a low level of disease cognition, which is easy to cause disease uncertainty and further aggravate social isolation.\u003c/p\u003e \u003c/p\u003e \u003cp\u003e \u003cstrong\u003eStoma status\u003c/strong\u003e \u003cp\u003ePatients with permanent stoma had a higher risk of social isolation than those with temporary stoma, which was consistent with the research of Wang et al \u003csup\u003e[29]\u003c/sup\u003e. Temporary stoma has a clear expectation of stoma reversal, and the physical changes are transient, so the psychological pressure of patients is light and social avoidance behavior is less \u003csup\u003e[30]\u003c/sup\u003e. However, permanent stoma leads to irreversible changes in physical function and image, making patients bear long-term care burden and stigma, and thus more prone to social isolation.\u003c/p\u003e \u003c/p\u003e \u003cp\u003e \u003cstrong\u003eStoma complications\u003c/strong\u003e \u003cp\u003ePatients with stoma complications had a higher risk of social isolation.

Stoma complications not only increase the physical discomfort and self-care burden of patients\u003csup\u003e[33]\u003c/sup\u003e, but also limit their physical activity ability, affect normal social interaction, and ultimately further increase the risk of social isolation \u003csup\u003e[34]\u003c/sup\u003e.\u003c/p\u003e \u003c/p\u003e \u003cp\u003e \u003cstrong\u003eStigma\u003c/strong\u003e \u003cp\u003eStigma is an important psychological factor leading to social isolation.

This result provides a clear direction for clinical intervention: clinical workers should focus on high-risk groups (female, rural residents, low social support, high psychological vulnerability), construct a three-dimensional support system of \"medical staff-family-patients\", carry out regular psychological assessment and counseling, and reduce the negative emotions caused by stoma. At the same time, medical staff can hold regular stoma patient fellowship meetings and build online communication groups to promote positive communication among patients, reduce the sense of loneliness and thus lower the level of social isolation \u003csup\u003e[39]\u003c/sup\u003e.\u003c/p\u003e \u003c/div\u003e"},{"header":"Conclusion","content":"\u003cp\u003eThis study included 22 alternative variables, and 8 important risk factors for social isolation in patients with colorectal cancer after stoma surgery were screened by LASSO and Logistic regression analysis. Five machine learning prediction models were constructed with these factors, and the results showed that the LR model had the best predictive performance, which can be used as a reliable screening tool for clinical workers to early identify the high-risk groups of social isolation.SHAP analysis revealed that gender, place of residence, social support and psychological vulnerability were the top 4 core influencing factors, which provided a scientific basis for formulating targeted clinical intervention strategies. Clinical workers can take targeted intervention measures for high-risk groups to reduce the incidence of social isolation and improve the quality of life of patients.\u003c/p\u003e \u003cp\u003eLimitations : This study is a cross-sectional study, which cannot track the dynamic development of social isolation in patients with colorectal cancer after stoma surgery. In addition, the samples were collected from a single tertiary hospital, and the sample representativeness is limited without external validation. In the follow-up study, the constructed model will be applied to stoma patients in other medical institutions and communities, and more external validation data will be collected to improve the generalization ability of the model. At the same time, a longitudinal study will be carried out to explore the dynamic change trajectory of social isolation in stoma patients and its influencing factors, so as to provide a more comprehensive basis for clinical intervention.\u003c/p\u003e"},{"header":"Declarations","content":"\u003cp\u003e\u003cstrong\u003eFunding Statement\u0026nbsp;\u003c/strong\u003eThe authors declare that no funds, grants, or other support were received for the preparation of this manuscript.\u003c/p\u003e\u003ch2\u003eEthical Approval\u003c/h2\u003e \u003cp\u003eThis study was approved by the Ethics Committee of Jinzhou Medical University (Approval No.: JZMULL2025404).

The data were randomly divided into a training set and a validation set at a ratio of 7:3. LASSO algorithm and Logistic regression analysis were combined to screen the risk factors. Five machine learning algorithms, namely Logistic Regression (LR), Support Vector Machine (SVM), Naive Bayes, K-Nearest Neighbor (KNN) and Decision Tree, were used to construct the prediction models for social isolation in stoma patients. The area under the receiver operating characteristic (ROC) curve (AUC), accuracy, sensitivity, specificity, precision and F1 score were used to evaluate and compare the predictive performance of the models. Finally, the optimal risk prediction model with the best predictability and practicability was selected for SHapley Additive exPlanations (SHAP) analysis to demonstrate the importance of predictive factors.\u0026nbsp;\u003c/p\u003e\n\u003cp\u003eResults Among the 507 patients with colorectal cancer after stoma surgery, 163 cases suffered from social isolation, with an incidence rate of 32.3%.
