The Neonatal Nursing Workforce Tool (2020) has been adapted from the CRG Workforce Calculator (Dinning) Tool (2013) and has been developed with the National Lead Nurses Group. It is intended to support neonatal nurse managers and their colleagues by providing a consistent method for the calculation of nursing establishment requirements which meet national standards i.e. BAPM (2022); NHSE Neonatal Service Specification (2024); NHS (2009).
