Abstract

Aims: There is well-established data linking the adequacy of nurse staffing to patient outcomes. Evidence-based standards for staffing are therefore critical to drive improvements in clinical care. One such evidence-based approach is the use of patient acuity-based tools. The objective of this study is to determine the performance of a neonatal acuity tool in an Australian tertiary neonatal health-care setting, focusing on the classification of patient acuity and nursing:patient staffing ratios compared to current practice.

Methods: Acuity data were collected in a neonatal intensive care unit (NICU) and special care baby unit (SCBU) over a 10-week period in 2023. Patient data were scored in the 16 domains at two time points (prior to morning and evening nursing shift changeover) for all admitted newborns.

Results: For ventilated newborns nursed with a nurse:patient staffing ratio of 1:1, 78% of scores were within the L4-high acuity (score ≥ 26) band, with the remaining scores within the L3-high acuity (18-25) band. For newborns on non-invasive respiratory support in NICU staffed 1:1, the proportion scoring within the L4 acuity band was higher in the nasal high-flow group compared to the nasal continuous positive airway pressure group (P = 0.032), an effect not seen for those nursed 1:2 in NICU or for those on nasal high-flow nursed in SCBU either 1:2 or 1:3.

Conclusion: This study of how a neonatal acuity classification system compares with current nurse:patient staffing allocations in an Australian tertiary NICU, suggests refinements in staffing ratios for specific patient groups on respiratory support are possible.
