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.

Objectives. To determine whether nurse staffing in California hospitals, where state-mandated minimum nurse-to-patient ratios are in effect, differs from two states without legislation and whether those differences are associated with nurse and patient outcomes. Data Sources. Primary survey data from 22,336 hospital staff nurses in California, Pennsylvania, and New Jersey in 2006 and state hospital discharge databases. Study Design. Nurse workloads are compared across the three states and we examine how nurse and patient outcomes, including patient mortality and failure-to-rescue, are affected by the differences in nurse workloads across the hospitals in these states. Principal Findings. California hospital nurses cared for one less patient on average than nurses in the other states and two fewer patients on medical and surgical units. Lower ratios are associated with significantly lower mortality. When nurses' workloads were in line with California-mandated ratios in all three states, nurses' burnout and job dissatisfaction were lower, and nurses reported consistently better quality of care. Conclusions. Hospital nurse staffing ratios mandated in California are associated with lower mortality and nurse outcomes predictive of better nurse retention in California and in other states where they occur.

Objectives Missed nursing care is an emerging problem negatively impacting patient outcomes. There are gaps in our knowledge of factors associated with missed nursing care. The aim of this study was to determine the relationship between the nursing practice environment and missed nursing care in acute care hospitals. Methods This is a secondary analysis of cross sectional data from a survey of over 7.000 nurses from 70 hospitals on workplace and process of care. Ordinary least squares and multiple regression models were constructed to examine the relationship between the nursing practice environment and missed nursing care while controlling for characteristics of nurses and hospitals. Results Nurses missed delivering a significant amount of necessary patient care (10–27%). Inadequate staffing and inadequate resources were the practice environment factors most strongly associated with missed nursing care events. Conclusions This multi-site study examined the risk and risk factors associated with missed nursing care. Improvements targeting modifiable risk factors may reduce the risk of missed nursing care.
