Abstract

This study aimed to examine the severity and predictive factors of postoperative complications within 30 days among colorectal cancer patients who met specific selection criteria. A total of 143 colorectal cancer patients attended postoperative appointments at a university hospital outpatient clinic. Data were collected through interviews using a questionnaire package that included personal data, nutritional status, perceived person-centered care, health literacy, and the severity of postoperative complications. The reliability of the perceived person-centered care and health literacy assessments was confirmed with Cronbach’s alpha coefficients of 0.92 and 0.95, respectively, and inter-rater reliability using the intraclass correlation coefficient of 0.94. Descriptive statistics, Pearson’s product-moment correlation coefficient, point-biserial correlation coefficient, and multiple regression analysis were used for data analysis.

The findings indicated that the average severity of postoperative complications was low (Mean = 17.82, S.D. = 7.56). Nutritional status, perceived person-centered care, and health literacy significantly predicted complication severity, accounting for 28% of the variance (Adjusted R2 = 28, F (4, 138) = 14.60, p <.05). Nutritional status (β = -.28, p <.001) and perceived person-centered care (β =-.28, p<.001) were the strongest predictors, followed by health literacy (β = -.24, p <.05).

The findings of this study provide a foundational framework for developing evidence-based guidelines to enhance preoperative nutritional status, implement person-centered care, and improve health literacy among surgical patients. These efforts aim to mitigate the severity of postoperative complications within the first 30 days following surgery.
