Abstract: Objective The aim of this study was to evaluate the quality level of treatment process for hospitalized surgical patients with colorectal cancer and explore its influencing factors,providing reference for improving the clinical treatment quality of colorectal cancer. Methods Medical record data were collected for patients with colorectal cancer who underwent surgical treatment at Harbin Medical University Cancer Hospital from March 2018 to March 2023.Nine process quality evaluation indicators were selected to calculate an individual scores,and patients were categorized into the high-and low-quality groups based on the median scores.The differences were compared in clinical and baseline characteristics between the high-and low-quality treatment process quality groups and to analyze the factors influencing treatment process quality. Results A total of 12,502 patients were included,with a median treatment process quality score of 0.44.There were statistically significant differences in family history of colorectal cancer,smoking status,body mass index(BMI),medical insurance type,fecal examination,endocrine therapy,chemotherapy,and alcohol consumption between the high-and low-treatment quality groups(P＜0.05).Multivariable logistic regression analysis showed that undergoing fecal testing,receiving endocrine therapy,receiving chemotherapy,and alcohol consumption were associated with a lower quality of the treatment process(P＜0.05).A family history of colorectal cancer,higher BMI,smoking,and having other types of medical insurance were associated with a higher quality of the treatment process(P＜0.05). Conclusion In clinical treatment,the application of process indicators should be strengthened,with a focus on the management of patients without a family history of colorectal cancer,underweight,and alcohol consumption.The associations between not receiving fecal examination and not receiving endocrine therapy and higher treatment process quality still needs further investigation,explanation,and verification.
