Abstract
OBJECTIVE: To evaluate staffing conditions, patient outcomes, quality of care, patient safety and nurse job outcomes in British Columbia (BC), Canada hospitals. DESIGN: Cross-sectional study of 58 hospitals in BC with surveys of nurses and independent measures of patient outcomes. SETTING: 58 hospitals in BC. PARTICIPANTS: 6685 hospital-based nurses working in a direct patient care role. EXPOSURES: Hospital-wide and unit-specific patient-to-nurse staffing ratios derived from registered nurse reports of how many patients and how many nurses were on their unit during their last shift worked. MAIN OUTCOMES AND MEASURES: Objective patient outcome measures included the Hospital Standardized Mortality Ratio (HSMR) and 30-day Readmission Rate, from 2022 to 2023 Canadian Institute for Health Information data. Nurses4All@BC provided data from 2024 using validated items on multiple measures (eg, nurse burnout, missed health breaks, intentions to leave, quality and safety measures such as culture of patient safety, quality of nursing care, missed nursing care). RESULTS: Burnout (59.4%), missed health breaks (41.7%), job dissatisfaction (36.0%), intentions to leave (19.3%) and patient outcomes (HSMR mean 95.4, median 96.0, range 26-180; readmission rate mean 10.0%, median 9.5%, range 7.9%-13.8%) were high and varied across hospitals. 68.3% of nurses reported there were not enough staff, and 77.3% reported their workloads were unsafe for patients. 60.6% of nurses gave their hospital an unfavourable patient safety rating. More patients per nurse were associated with poorer hospital mortality and readmission rates, poorer job outcomes for nurses, more adverse events for patients, less favourable ratings of quality of care and patient safety, more missed nursing care and poorer ratings of staffing adequacy and management. CONCLUSIONS: Given the variability in staffing, quality and patient outcomes across BC hospitals, the implementation of a minimum nurse-to-patient ratio policy has the potential to improve patient care safety and retention of nurses.
