ObjectiveTo analyze the association between the cultural level and hospitalization management process and length of hospitalization of the colorectal patients served by West China Hospital of Sichuan University as a regional center in the current version of the Database from Colorectal Cancer (DACCA). MethodAccording to the established screening criteria, eligible colorectal cancer patients were collected from the updated version of DACCA on June 29, 2022. The analyzed data items included gender, age, BMI, blood type, marriage, waiting time before admission, preoperative hospitalization time, postoperative hospitalization time, total hospitalization time, and management process, and patients were divided into illiterate group, primary education group, medium education group, and higher education group according to their educational level, then compared the hospitalization management process and length of hospitalization of each group. ResultsA total of 4 765 eligible data were screened, with secondary education being the most prevalent (2 792, 58.6%), followed by primary (1 337, 28.1%) and higher education (417, 8.7%), and illiteracy being the least prevalent (219, 4.6%). In the classification of management processes, “regular” account for the majority (4 219, 88.5%), followed by “enhanced”(274, 5.8%), “individual” was third (231, 4.8%), and “rapid” was the least (41, 0.9%). There was no statistically significant difference in the comparison of waiting time before admission, preoperative hospitalisation time and postoperative hospitalisation time among patients with different literacy levels (P=0.371, P=0.095, P=0.352), but there was a statistically significant difference in total hospitalisation time (P=0.021), with a significant difference in total hospitalisation length between illiterate patients and patients with medium education (P=0.041). There was no statistically significant difference in the comparison of inpatient management processes of patients in different literacy groups (χ2=15.2, P=0.085). ConclusionsAnalysis of the DACCA data revealed a statistically significant difference in total hospitalisation time between patients with illiteracy and those with medium education. However, the choice of hospitalisation management process was similar for patients with different literacy levels, which needs to be further analysed for the reasons.
ObjectiveTo analyze the impact of preoperative hypoproteinemia on postoperative complications in patients with rectal cancer based on the current version of the Database from Colorectal Cancer (DACCA). MethodsThe patient information was extracted from the updated version of DACCA in April 2024 according to predefined inclusion criteria. The preoperative hypoproteinemia and incidence of complications were analyzed. The univariate and multivariate logistic regression analyses were performed to identify risk factors for complications in three postoperative periods (in-hospital, short-term, and long-term). The test level was α=0.05. ResultsA total of 1 440 patients with rectal cancer were included, 322 (22.4%) with preoperative hypoproteinemia and 1 118 (77.6%) without. Compared to the patients without preoperative hypoproteinemia, those with preoperative hypoproteinemia were older (P<0.001), had a lower body mass index (P<0.001), smaller tumor margins (P<0.05), and a higher proportion of patients with pTNM stage Ⅲ or Ⅳ (P<0.001). There were no statistically significant differences in the overall incidence of complications during the three postoperative periods (in-hospital, short-term, and long-term) between the patients with and without preoperative hypoproteinemia (χ2=0.399, P=0.280; χ2=0.298, P=0.585; χ2=1.416, P=0.234). Except for urinary retention, there were no significant differences in the incidence of specific complications between the two groups (P>0.05). The univariate and multivariate logistic regression analyses did not identify preoperative hypoproteinemia as a risk factor for postoperative complications (P>0.05). ConclusionsThe results of this study suggest that the incidence of preoperative hypoproteinemia is higher in patients with rectal cancer. Patients with preoperative hypoproteinemia tend to be older, have a lower body mass index, and a higher proportion of pTNM stage Ⅲ or Ⅳ. However, it was not found that preoperative hypoproteinemia is a risk factor for postoperative complications.
