Is nurse staffing associated with critical deterioration events on acute and critical care pediatric wards? A literature review

Pediatric and neonatal patients admitted to acute and critical care wards may experience critical deterioration events that may lead to unexpected deaths if unrecognized and untreated promptly. Adequate levels and skill-mix of nurse staffing are essential for the quality of patient monitoring and response to deteriorating patients. Insufficient staffing may have an impact on the occurrence of missed care and consequently on critical deterioration events, increasing the risk of mortality and failure-to-rescue. To review the literature to explore the association between nurse staffing levels or skill-mix and pediatric and neonatal critical deterioration events, such as mortality, pediatric intensive care unit (PICU)/neonatal intensive care unit (NICU) unplanned admissions, cardiac arrests, and failure-to-rescue. A structured narrative literature review was performed. Pubmed, Cinhal, and Web of Science were searched from January 2010 to September 2022. Four independent reviewers conducted the study screening and data extraction. The quality of the studies included was evaluated using the Joanna Briggs Institute critical appraisal tools. Out of a total of 2319 studies, 15 met the inclusion criteria. A total of seven studies were performed in PICU, six in NICU, and two in general pediatric wards. Nurse staffing measures and outcomes definitions used were heterogeneous. Most studies suggested nursing skill-mix, increased working experience, or higher nursing degrees were associated with increased survival in PICU. Decreased nursing staffing levels were associated with increased mortality in NICU and mechanically ventilated patients in PICU.

Conclusion: Evidence on the association of nurse staffing and critical deterioration events in PICU and NICU is limited, while there is no evidence reported for pediatric wards. Future research is needed to determine adequate levels of nurse/patient ratios and proportion of registered nurses in the skill-mix for pediatric acute and critical care nursing to improve outcomes on in-patient wards.
