Background

Consequences of nurse staffing levels (Aiken et al., 2002;
Lang et al., 2004, Mark et al., 2004)
Patient outcomes: inpatient mortality, failure to
rescue
 Nurse outcomes: burnout, dissatisfaction
 Hospital: length of stay


Trends in nurse staffing (Bond et al., 2000; Buerhaus & Staiger, 1999)
not necessarily aligned with perception of
staffing levels (Aiken et al., 2000)
Why is perception of adequate
staffing important?

Staffing perceptions associated with…
Job satisfaction, organizational and professional
commitment (DeGroot et al.., 1998)
 Lower perception of quality of care at the hospital
level, quality of nursing care on the last shift (McCusker et
al., 2004), and perception of own ability to provide
quality care (Escoto & Karsh, 2006; Williams, 1998)
 Nurse safety outcomes (e.g., needlestick injuries) (Clarke et al.,

2002)

Despite importance of staffing perceptions
there has been little exploration of its predictors
in the literature (e.g., Mark, 2004)
What are the predictors of perception of
staffing/resource adequacy?
Model based on the literature (Kramer & Schmalenberg, 2002; Kramer et al., 2004) and
Demand-Control-Support theory of job design (Karasek, 1979; Johnson & Hall, 1988)

Interaction – Job demands & Social support
Conclusions




Improving conditions of work as important as
determining optimal levels of nurse staffing
Interventions supporting freedom to be creative,
feedback mechanisms, and collaboration between
nurses and physicians are essential
Social support may help alleviate burden on nurses, but
at high demand levels may be counterproductive
Limitations



Cross-sectional design
Scale measurement (job control variables)
External validity
