While the association between clinician burnout and patient safety are not new, the COVID-19 pandemic brought this safety concern back to the forefront. In this study conducted at 60 US Magnet hospitals, nurses and physicians reported high levels of burnout and rated their hospital unfavorably on patient safety. Increased nurse staffing was the top recommendation to reduce burnout with less emphasis on wellness and resilience programs.

Operational failures – breakdowns in care processes, such as distractions or situational constraints – can impact healthcare delivery. This cross-sectional analysis using population-based survey data from 11,709 nurses examined the relationship between operational failures, patient satisfaction, nurse-reported quality and safety, and nurse job outcomes. Findings indicate that operational failures negatively impact patient satisfaction, quality and safety, and contribute to poor nurse job outcomes, such as burnout.  

Missed steps in the diagnostic process, such as timely referral for surgical consultation, can lead to missed or delayed diagnoses. This large, retrospective cohort study using Medicare data identified disparities between Black and White patients in receipt of consults for emergency surgery. Findings show that Black patients had lower odds of receiving a surgical consultation after being admitted from the emergency department; these disparities remained after adjusting for medical comorbidities, socioeconomic factors, and individual hospital-level effects.

While research shows that better nurse staffing ratios are associated with improved patient outcomes, policies setting minimum nurse-to-patient ratios in hospitals are rarely implemented. In 2016, select Queensland (Australia) hospitals implemented minimum nurse staffing ratios. Compared to hospitals that did not implement minimum nurse staffing ratios, length of stay, mortality, and readmission rates were significantly lower in intervention hospitals, providing evidence, once again, that minimum staffing ratios can improve patient outcomes.

The nursing work environment affects patient safety. This cross-sectional study surveyed nearly 2000 pediatric acute care nurses about their work environment and safety culture. Researchers measured the hospital work environment using a validated scale, and they assessed safety using the AHRQ Survey on Patient Safety Culture. A culture of blame and fear of speaking up remained prevalent among nurses participating in this survey. As with prior studies, investigators found an association between a high-functioning work environment and positive safety culture. The authors recommend enhancing pediatric acute care work environments for nurses in order to improve patient safety. A previous PSNet interview discussed how nurse staffing and the work environment can affect patient safety and outcomes.

Prior research suggests that improved nursing resources may be associated with decreased mortality and adverse events. However, less is known about how changes to nursing resources in the inpatient setting may affect quality and safety over time. In this study involving 737 hospitals and survey data from nurses obtained in 2006 and 2016, researchers found that after adjusting for numerous factors, better nursing resources in terms of work environment, staffing, and education was associated with improvement in quality and patient safety outcomes. A PSNet perspective discussed the impact of nursing resources on patient safety.

This cross-sectional study found that nurses reporting a lower level of engagement also described worse patient safety in their work environment. These concerns were exacerbated when higher patient–nurse staffing ratios were present. The authors suggest that increasing nurse engagement may improve patient safety.

Missed nursing care is common and has been linked to adverse events. This survey found that more than half of pediatric intensive care unit nurses reported missing care during their prior shift. Higher patient loads and poor working environments were associated with more episodes of missed care, corroborating prior research.

Researchers analyzed patient discharge data and hospital characteristics, as well as patient and nurse survey data, across adult acute care hospitals in six European countries. After adjusting for hospital and patient variables, they found that hospitals in which nursing care was provided to a greater degree by skilled nurses had lower odds of mortality. The authors argue against replacing professional nurses with nursing assistants and suggest that doing so may compromise patient safety by increasing preventable deaths.

Nurses play a critical role in patient care through their constant presence at patients' bedsides, and they may have key insights into safety in their institutions. This study found that in hospitals where nurses rated quality of care as excellent, 30-day postsurgical mortality was better. The authors suggest that nursing perceptions of safety can inform targeting of improvement interventions.

This survey of nurses found that those who rated their work environment as poor were more likely to report quality and safety problems, underscoring the well-described link between nurses' working conditions and patient safety. Improving nurse working conditions is a patient safety strategy.

Hospital readmissions are an increasing focus of patient safety efforts, due to Medicare's payment policy. This cross-sectional study sought to assess the link between working environments for nurses and readmissions. Suboptimal working conditions for nurses have been associated with poor patient outcomes. One proposed mechanism to explain this relationship is missed nursing care. Researchers found that hospitals with worse ratings of nurses' work environment and more frequent reports of missed care also had higher readmissions for heart failure. Although this study does not ascertain whether the working conditions or missed care caused the readmissions, the authors suggest that prospective studies looking at missed nursing care and subsequent readmissions are warranted. A recent AHRQ WebM&M perspective discusses the nursing workforce and patient safety.

Although 12-hour nursing shifts are common in the United States, this study found that only 15% of European nurses worked 12 hours or more. Similar to prior research, longer nursing shifts were associated with lower quality of care and compromised patient safety. This study also found that nurses working extended shifts reported more care left undone. Nurses who worked overtime, even if shift length was less than 10 hours, described similar concerns. The authors warn that policies to adopt standard 12-hour nursing shifts as a cost-effective way of maintaining nurse–patient ratios may contribute to burnout. A past AHRQ WebM&M interview with Barbara Blakeney discussed the importance of proper nursing staffing for patient safety, and a prior AHRQ WebM&M commentary examines the complexities around balancing nurse staffing and workload.

This retrospective cohort study across nine European countries revealed that higher patient–nurse staffing ratios increased the likelihood of inpatient mortality. A larger proportion of nurses with bachelor's degrees decreased this risk, consistent with previous research that found a relationship between nurse education levels and patient outcomes. This finding emphasizes the importance of maintaining an adequately staffed and trained nursing workforce to support safety in hospitals.

Nurses are frequently forced to prioritize tasks during busy shifts, leading to some nursing care being left undone. In this multinational European study, nurses most frequently omitted time-intensive but critical practices such as talking with, educating, and providing comfort for patients.
