Patients admitted to the hospital on the weekend have been shown to experience worse outcomes compared to those admitted on weekdays. This weekend effect has been observed numerous times across multiple health care settings. However, whether patient characteristics (patients admitted on the weekend may be more severely ill) or system factors (less staffing and certain services may not be available on the weekend) are primarily responsible remains debated. In this systematic review and meta-analysis including 68 studies, researchers found a pooled odds ratio for weekend mortality of 1.16. Moreover, the weekend effect in these studies was more pronounced for elective rather than unplanned admissions. They conclude that the evidence suggesting that the weekend effect reflects worse quality of care is of low quality. A past PSNet perspective discussed the significance of the weekend effect with regard to cardiology.

Missed nursing care has been linked to safety problems, but ensuring reliable levels of nurse staffing remains challenging. This report provides the results of a 3-year investigation into whether tracking of vital signs by nursing staff could serve as a viable measure for safe patient coverage. The report identified correlations between low staffing, missed vital sign observation, length of stay, and likelihood of mortality. However, record review found no direct relationship between safety and staffing levels. A PSNet perspective examined the relationship between missed nursing care and patient safety.

Excessive nursing workload is a known safety issue. This study examined whether nurse workload in the neonatal intensive care unit affected the quality of nursing care. Investigators measured workload using patient–nurse ratios, taking into account patient acuity, and a convenience sample of nurses also reported their perceived workload. Participating nurses were asked to report the care they provided, and missed care was defined as self-reported failure to provide any of 11 prespecified essential elements of nursing care. The authors identified a consistent association between perceived workload and missed care, suggesting that nurses' own assessments of their workload should be a safety consideration. A PSNet perspective explores how missed nursing care may explain the association between low nurse staffing levels and increased mortality in hospital patients.

Prior research has shown that missed nursing care may in part result from reduced nurse staffing and is associated with adverse outcomes for patients. Using survey data from a sample of nurses at a single community hospital, researchers found that reduced nurse staffing, lower job satisfaction, and decreased satisfaction with teamwork were important factors related to missed nursing care.
