Does Quality Improvement Implementation Affect Hospital Quality of Care?

The authors examined how the association between quality improvement (QI) implementation in hospitals and hospital clinical quality is moderated by hospital organizational and environmental context. The authors used Ordinary Least Squares regression analysis of 1,784 community hospitals to model seven quality indicators as a function of four measures of QI implementation and a variety of control variables. They found that forces that are external and internal to the hospital condition the impact of particular QI activities on quality indicators: specifically data use, statistical tool use, and organizational emphasis on Continuous Quality Improvement (CQI). Results supported the proposition that QI implementation is unlikely to improve quality of care in hospital settings without a commensurate fit with the financial, strategic, and market imperatives faced by the hospital.
