Objective  To analyze the basic characteristics of hospitalized patients with colorectal cancer (CRC), to estimate the hospitalization scale, medical resource utilization, and cross-regional hospitalization of CRC inpatients in Sichuan Province, which will provide data support for scientifically formulating colorectal cancer medical resource allocation measures. Methods  Based on the hospital discharge records of CRC inpatients collected from secondary hospitals and tertiary hospitals in Sichuan Province between 2015 and 2019, descriptive statistical analysis was performed and the cross-geographical hospitalizations was visualized using a directed network. Results  During the study period, the number of CRC inpatients and hospitalizations increased with time. The average age of CRC inpatients in 2019 was 65.1 years, an increase of 1.5 years in the 5-year-period. The proportion of men was relatively high (about 60.1%) and remained stable in the 5-year-period. The median length-of-stay of CRC inpatients per year was 25 days (IQR: 13 days, 45 days), and inpatients in urban areas were 2 days longer than that in rural areas. The median hospitalization cost of CRC inpatients per year was 32 900 yuan (IQR: 11 200 yuan, 59 300 yuan), men were 500 yuan higher than women, and patients in urban areas were 9 900 yuan higher than that in rural areas. From 2016 to 2019, 13.9% hospitalizations (59 512 hospitalizations) were cross-geographical hospitalizations, where Chengdu had the lowest outflow rate (1.0%) and the highest inflow rate (29.3%). Conclusions  CRC inpatients showed an aging trend, and the number of hospitalizations and annual hospitalization costs increased year by year. Cross-geographical hospitalizations mainly flow to the provincial medical center and a small part flow to the regional medical centers.
