Impact of workforce flexibility on quality of care: moderating effects of workload and severity of illness

Abstract

PurposeAs a way of alleviating nursing workforce shortages, health care managers are employing two types of workforce flexibility: supplemental staffing and floating among units. In this paper, the authors investigate the moderating effects of two critical situational variables – namely, job-level workload and severity of illness (SOI) in a given unit – on the relationship between workforce flexibility and quality of care as assessed by the nurses at the unit-level.Design/methodology/approachThe authors empirically test the relationship between a unit's floating of nurses and the use of supplemental workforce on the quality of patient care and the moderating role of patient SOI and job-level workload on this relationship using 357 hospital-unit observations.FindingsThe authors find that situational variables play a critical role in flexible staffing strategies and they should be accounted for carefully to obtain the best quality of care outcomes. The authors find that the well-known negative effect of supplemental staffing on quality of care is not universal and appears to be moderated by the situational factors studied in this paper.Practical implicationsFor best outcomes, staffing manager who oversee multiple units should use supplemental staff on units that have lower job-level workload and on units that have high severity of illness. The authors also find that managers of units with patients who are less-severely ill should encourage nurses to float out and return to their home unit. This strategy will improve quality of patient care in the home unit.Originality/valueWhile some research analyzes the direct link between flexibility and quality performance, how this relationship is affected by varying situational factors within a unit has not been studied so far.
