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) Job Demands Task control Resource control Skill discretion Social support Nurse-physician relations Feedback Staff/resource adequacy (SRA) Methods Analysis of data from a larger study of working conditions, outcomes, and technology with pediatric nurses Design: Cross-sectional, survey design Sample: Free-standing, academic pediatric hospital with 222 beds and 9 inpatient units Staff nurses employed in 3 units Pediatric Intensive Care Unit Medical/Surgical Hematology-Oncology-Transplant Statistical Analysis Data preparation for regression analyses Factor analysis Reliability (Cronbach’s a) Descriptive statistics & Bivariate correlation Two regression models Block 1.

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 Acknowledgments This research was supported by AHRQ-1 R01 HS013610 (Bar Coding and Employee and Patient Safety) Bar Coding and Employee and Patient Safety Research Team Dr. Ben-Tzion Karsh (University of Wisconsin, Madison) Samuel Alper (University of Wisconsin, Madison) Judy Arnold (Vanderbilt Children’s Hospital) Dr. Patricia Brennan (University of Wisconsin, Madison) Dr. Roger Brown (University of Wisconsin, Madison) Richard Holden (University of Wisconsin, Madison) Dr. Rainu Kaushal (Brigham and Women's Hospital) Kathy Murkowski (Children’s Hospital of Wisconsin) Dr. Neal Patel (Vanderbilt Children’s Hospital) Dr. Matt Scanlon (Children’s Hospital of Wisconsin) Kathleen Skibinski (University of Wisconsin-Madison) Questions?
