ABSTRACT

Numerous research has shown how registered nurses contribute to safe patient care. However, the majority of the data connecting staffing levels to results is cross-sectional and has inherent limitations, such as the inability to prove that the effect's putative cause (staffing) came first. In this investigation, we looked for and assessed the data from longitudinal studies demonstrating a link between nurse team levels, including the composition of the nursing team, and patient outcomes in ICU. We carefully analysed studies that used a longitudinal technique to assess the connection between nurse team level and patient outcomes. Studies imply repeated cross-sectional analyses were ignored unless a difference-in-difference approach was used. We searched Cochrane Library, CINAHL, Medline and Embase up until 2022. We combined the findings and organised them in a narrative and tabular fashion. Our findings further support the probable causal relationship between low registered nurse staffing and patient mortality provided by estimates of linkages from longitudinal research. In order to address residual uncertainty, future research should be conducted at numerous hospitals and report staffing numbers using standard measures.
