Discharge teaching quality positively predicts quality of life in colorectal cancer patients with temporary enterostomy: The mediating role of readiness for hospital discharge and stoma self-efficacy.

Abstract

This study aimed to examine the mediating role of readiness for hospital discharge (RHD) and stoma self-efficacy (SSE) in the relationship between quality of discharge teaching (QDT) and health-related quality of life (HRQOL) in colorectal cancer patients with temporary enterostomy, and the gender difference of mediating effect. It is not clear how RHD, QDT, SSE and HRQOL interact in colorectal cancer patients with temporary enterostomy. This was a prospective follow-up survey. 221 colorectal cancer patients with temporary enterostomy were conveniently recruited from a general hospital in Southeast China. The Quality of Discharge Teaching Scale, Readiness for Hospital Discharge Scale, Stoma Self-Efficacy Scale, and Stoma Quality of Life Scale were used to collect data. Pearson's correlation and structural equation models were used to analyze the data. SPSS 26.0 and Amos 28.0 software were used for analysis the collected data. Regarding the relationship of QDT and HRQOL, only QDT-T had a direct effect among colorectal cancer patients with stomas (b = 0.233, P<0.001, percentile 95% CI = [0.145, 0.314]). However, both QDT-T and QDT-R can predict HRQOL indirectly through three paths: (1) the mediating role of SSE (b = 0.050, P = 0.009, percentile 95% CI = [0.013, 0.098]; b = 0.077, P = 0.008, percentile 95% CI = [0.021, 0.164]), (2) the mediating role of RHD (b = 0.044, P = 0.004, percentile 95% CI = [0.014, 0.085]; b = 0.044, P = 0.005, percentile 95% CI = [0.010, 0.102]), and (3) the chain mediating role of SSE and RHD (b = 0.030, P = 0.003, percentile 95% CI = [0.011, 0.059]; b = 0.047, P = 0.003, percentile 95% CI = [0.015, 0.103]). The similar chain mediating effect in male stoma patients was also found (b = 0.041, P = 0.002, percentile 95% CI = [0.016, 0.080]; b = 0.046, P = 0.004, percentile 95% CI = [0.011, 0.114]). Stoma self-efficacy and readiness for hospital discharge played important intermediary roles in the relationship between quality of discharge teaching and health-related quality of life in colorectal cancer patients with stomas. Health care providers can design SSE-enhancing and RHD-enhancing discharge planning for colorectal cancer patients with temporary enterostomies.
