This study investigates the effectiveness of combining psychological nursing with extended nursing in patients with colorectal cancer who have undergone enterostomy. Conducted from January 2021 to January 2022, this retrospective study involved 78 patients split into 2 groups of 39 each. The control group received standard nursing care, while the observation group benefitted from both psychological and extended nursing. The evaluation focused on anxiety, depression, sleep quality, mental resilience, and self-care abilities. Results, 3 months postdischarge, indicated that the observation group had significantly lower scores in the Hamilton Depression Rating Scale and the Pittsburgh Sleep Quality Index, and higher scores in the Connor-Davidson Resilience Scale and the Enterostomal Self-Care Ability Scale, compared to the control group (P < .05). The findings suggest that integrating psychological nursing with extended care significantly improves mood, sleep quality, psychological resilience, and self-care capabilities in these patients.
