Context Better hospital nurse staffing, more educated nurses, and improved nurse work environments have been shown to be associated with lower hospital mortality. Little is known about whether and under what conditions each type of investment works better to improve outcomes. Objective To determine the conditions under which the impact of hospital nurse staffing, nurse education, and work environment are associated with patient outcomes. Design, Setting, and Participants Outcomes of 665 hospitals in four large states were studied through linked data from hospital discharge abstracts for 1,262,120 general, orthopedic, and vascular surgery patients, a random sample of 39,038 hospital staff nurses, and American Hospital Association data. Main outcome measures 30-day inpatient mortality and failure-to-rescue. Results The effect of decreasing workloads by one patient/nurse on deaths and failure-to-rescue is virtually nil in hospitals with poor work environments, but decreases the odds on both deaths and failures in hospitals with average environments by 4%, and in hospitals with the best environments by 9 and 10% respectively. The effect of 10% more BSN nurses decreases the odds on both outcomes in all hospitals, regardless of their work environment, by roughly 4%. Conclusions While the positive effect of increasing percentages of BSN nurses is consistent across all hospitals, lowering the patient-to-nurse ratios markedly improves patient outcomes in hospitals with good work environments, slightly improves them in hospitals with average environments, and has no effect in hospitals with poor environments.

Patient satisfaction is receiving greater attention as a result of the rise in pay-for-performance (P4P) and the public release of data from the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey. This paper examines the relationship between nursing and patient satisfaction across 430 hospitals. The nurse work environment was significantly related to all HCAHPS patient satisfaction measures. Additionally, patient-to-nurse workloads were significantly associated with patients’ ratings and recommendation of the hospital to others, and with their satisfaction with the receipt of discharge information. Improving nurses’ work environments, including nurse staffing, may improve the patient experience and quality of care.
