Comparative Study
Identifying worsening surgical site infection performance: control charts versus risk-adjusted rate outlier status.
Control charts are used in industry to monitor performance and are being used increasingly in hospitals as a quality improvement tool. The authors' objective was to determine if control charts using surgical site infection (SSI) rates predict changes in outlier status for risk-adjusted SSI rates using data from a surgical registry, the American College of Surgeons National Surgical Quality Improvement Program. Control charts of monthly SSI rates for 100 hospitals were analyzed for indicators of a performance change in 2009 (vs 2008) using standard rules. ⋯ There was moderate agreement between these methods (weighted κ = 0.401). Control charts predicted nonworsening performance well (specificity = 92.9%) and identified changes in SSI performance sooner; however, they failed to identify 31.2% of hospitals with worsened outlier status. This study demonstrates that these quality measurement tools have unique strengths and weaknesses and are complementary uses of the same clinical data source.

In this study, the relationship between patients' perceptions of pain control during hospitalization and their overall satisfaction with care was examined. Satisfaction data were collected from the federally mandated Hospital Consumer Assessment of Healthcare Providers and Systems survey for 4349 adult patients admitted to any surgical unit over an 18-month period. Patients' perceptions of pain control and staff's efforts to control pain were associated with their overall satisfaction scores. ⋯ Interestingly, patient satisfaction was more strongly correlated with the perception that caregivers did everything they could to control pain than with pain actually being well controlled. The odds of a patient being satisfied were 4.86 times greater if pain was controlled and 9.92 times greater if the staff performance was appropriate. Hospitals may improve their patients' satisfaction by focusing on improving the culture of pain management.
