To describe newly licensed nurses’ shift work characteristics and determine the association between shift type and scheduling characteristics and nurse injury, before and after adjusting for individual and combined effects of demographics, external context, organizational context, and work context, following the Organization of Work model.
This study is a secondary analysis of a nationally representative survey of newly licensed registered nurses using a cross-sectional design.
The analytic sample includes 1744 newly licensed registered nurses from 34 states and the District of Columbia who reported working in a hospital and were within 6–18 months of passing their state licensure exam at the time of survey administration.
Descriptive statistics were calculated, followed by bivariate and multivariate Poisson regression models to assess the relationship between shift type and scheduling characteristics and nurse injury. Lastly, full models with the addition of demographics, external context, organizational context, and work context variables were calculated.
The majority (79%) of newly licensed nurses worked 12-h shifts, a near majority worked night shift (44%), and over half (61%) worked overtime (mandatory or voluntary) weekly. Nurses working weekly overtime were associated with a 32% [incidence rate ratio (IRR) 1.32, CI 1.07–1.62] increase in the risk of a needle stick and nurses working night shift were associated with a 16% [IRR 1.16, CI 1.02–1.33] increase in the risk of a sprain or strain injury.
Overtime and night shift work were significantly associated with increased injury risk in newly licensed nurses independent of other work factors and demographic characteristics. The findings warrant further study given the long-term consequences of these injuries, costs associated with treatment, and loss of worker productivity.
