RESUMEN
Objective: To analyze the main disease composition of children hospitalized in pediatric surgery, explore the correlation between disease types and gender, and provide a reference for hospital management and pediatric disease prevention. Methods: Using ICD-10 codes as the classification standard for disease diagnosis, a statistical analysis was conducted on the disease composition of children hospitalized in the Pediatric Surgery Department of the Second Affiliated Hospital of Xi'an Jiaotong University from January 1, 2015, to December 31, 2015, followed by the establishment of a clinical database. A total of 1647 male patients and 817 female patients were enrolled in the study, resulting in a male-to-female ratio of 2:1. The age range of the patients spanned from 0 to 18 years, with a marked imbalance in patient distribution among the various age groups. Statistical analysis was conducted using SPSS version 18.0 software. A chi-square test was performed to analyze the differences in the composition of disease systems and the composition of major diseases in terms of sex and age. Results: Pediatric patients were admitted with complex and diverse diseases in 2015, involving 15 systems of the human body and 400 diseases. Digestive system diseases, tumors, congenital malformations, and genitourinary system diseases were the top four diseases accounting for 83.5% of all pediatric cases. 561 patients were aged 0 years, accounting for 22.3% of all cases, while 1,801 patients fell within the 0-5 years age group, constituting 73.1% of the total. The differences in disease system composition among different sex and age groups of pediatric surgical inpatients were statistically significant (P = .001). There are statistically significant differences in the length of hospital stay and hospitalization costs among pediatric surgical inpatients in different age groups (P = .001). Conclusion: To strengthen the diagnosis and treatment of pediatric surgical diseases, we should strengthen the construction of key departments, optimize the consultation process according to the characteristics of children's disease spectrum, and improve the level of diagnosis and treatment of pediatric surgical diseases.
