The effect of fragmented cancer care and change in nurse staffing grade on cancer patient mortality

Abstract

Background: Continuity of patient care ensures timely and appropriate care and is associated with better patient outcomes among cancer patients. However, the impact of nurse staffing grade changes on patient outcomes remains unknown.

Aims: This retrospective cohort study aimed to evaluate the effect of fragmented care and changes in nurse staffing grade on the survival of colorectal cancer patients who underwent surgery.

Methods: This study included 2228 newly diagnosed colorectal cancer patients. Fragmented care was defined as the receipt of treatment in multiple hospitals and was divided into three categories based on changes in nurse staffing grade. Five-year survival rates were used to evaluate the effect of fragmented care and nurse staffing grade on outcomes of cancer patients. Survival analysis was performed by adjusting for covariates using the Cox proportional hazards model for 5-year mortality.

Results: Approximately 18.5% of patients died within 5 years; the mortality rate during cancer treatment was higher in patients who received fragmented care, especially in those transferred to hospitals with fewer nurses. Patients who received fragmented care had shorter survival times, and those transferred to hospitals with fewer nurses had higher risks of 5-year mortality (hazard ratio: 1.625; 95% CI: [1.095, 2.412]). Transfers to hospitals with fewer nurses were associated with increased mortality rates in low-income patients, hospitals located in metropolitan and rural areas, and high-severity groups.

Linking evidence to action: Receipt of fragmented care and change in nurse staffing grade due to patients' transfer to different hospitals were associated with increased mortality rates in cancer patients, thus underlining the importance of ensuring continuity and quality of care. Patients from rural areas, from low-income families, and with high disease severity may have better outcomes if they receive treatment in well-staffed hospitals.
