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.

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.

Health care work environments can influence safety culture and teamwork. This study used multiyear survey data from registered nurses in 503 hospitals across four states to explore the association between nurse work environment and healthcare quality, patient safety, and patient outcomes. Findings indicate that nurse work environment (such as nurse participation in hospital affairs, nurse manager capability, leadership support, and nurse-physician relationships) is an important factor to improving the experiences of patients and nurses, especially those in hospitals caring for economically disadvantaged patients.

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.

Prior research has shown that lower nurse-to-patient ratios are associated with increased patient mortality. This cross-sectional analysis using multiple data sources from four states assessed the relationship between nurse staffing and survival disparities after in-hospital cardiac arrest. Results indicate that disparities in survival between Black and white patients may be linked to medical-surgical nurse staffing levels, and that the benefit of being treated at a hospital with higher staffing ratios may be especially pronounced for Black patients.

This study used survey data from nurses and patients in 254 hospitals in New York and Illinois between December 2019 and February 2020 to determine the association between nurse staffing and outcomes, patient experience, and nurse burnout. A significant number of nurses who experienced burnout viewed their hospitals’ safety unfavorably and would not recommend their hospital. Analyses indicated that each additional patient per nurse increased the odds of unfavorable reports from nurses and patients and demonstrates the implications of understaffing, even before COVID-19.

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.

Factors in the hospital work environment can affect nurses' ability to provide safe care. In this survey study, investigators examined trends in nurse ratings of their work environment and patient ratings of care quality at 535 hospitals between 2005 and 2016. Over this time frame, about 20% of hospitals showed significant improvements in work environment scores, while 7% of hospitals demonstrated declining scores. There was an association between an improving work environment and better patient satisfaction. The authors conclude that lack of improvement in work environments may worsen safety culture and impede efforts to enhance patient safety. A PSNet interview with Linda Aiken discussed how nurse staffing and the work environment can affect patient safety and outcomes.

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 may result from inadequate nurse staffing and explain the relationship between nurse-to-patient ratios and patient outcomes. Research has shown that higher nurse staffing levels are associated with lower inpatient mortality and that reduced staffing increases the risk for postoperative complications. In this study, investigators examined data from more than 400,000 surgical patients from 300 hospitals in 9 countries as well as survey responses from 26,516 nurses. They found a significant association between nurse staffing and missed nursing care with 30-day risk-adjusted postoperative mortality. The authors conclude that measuring missed nursing care may help identify patients at greater risk for adverse outcomes earlier in their course. A past WebM&M commentary highlighted important issues associated with nurse staffing ratios.

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.

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.
