Aims: Use of temporary nursing staff is contentious and expensive. Using e-rostering data from 77 hospital units, this research investigates whether longer roster lead-times reduce temporary staff usage.
Background: It is commonly assumed that longer roster approval lead-times, the time from when a roster is approved, to when it is worked, result in better, more cost-effective rosters. Consequently, many hospitals target lead-times of 6 weeks, a figure recommended for the UK National Health Service in a recent governmental review. This contrasts with the minimum lead-time advocated by New South Wales Ministry of Health, which advises a shorter lead-time of 2 weeks. Using data from 77 hospital units, this paper explores this assumed relationship.
Design: Using data extracted from the e-rostering system of an NHS Acute Foundation Trust, this study uses linear regression analysis to explore the relationship between roster approval lead-time and temporary staff usage. The data were captured over a period of 9 months from 15 February 2016-23 October 2016, a total of 693 rosters.
Results/findings: This research suggests that late roster approval may contribute to as much as 37% of temporary staff usage, while approval 4-6 weeks prior to the roster being worked reduces this to approximately 15%. However, this is only relevant under specific conditions. Importantly, this should be considered before mandating lead-times across all units.
Conclusions: This research implies that the optimum approval lead-time lies between 4-6 weeks; however, given other challenges, achieving this in practice may prove difficult.
