Performance measurement is also undertaken to meet external needs and demands buy cheap albendazole 400 mg on line, including healthcare provider accountability, decision mak- ing, public reporting, organizational evaluation, and support for national performance-improvement goals and activities. Healthcare purchasers and payers are demanding that providers demonstrate their ability to provide high-quality patient care at fair prices. Specifically, they are seeking objec- tive evidence that hospitals and other healthcare organizations manage their costs well, satisfy their customers, and have desirable outcomes. Consumers are interested in care-related information for selection purposes. That is, Numerous opportunities for improvement exist in every healthcare organ- ization. Improvements that are powerful and worthy of organization resources include those that will positively affect a large number of patients, elimi- nate or reduce instability in critical clinical or business processes, decrease risk, and ameliorate serious problems. In short, it may be most appropri- ate to focus on high-risk, high-volume, problem-prone areas to maximize your performance-improvement investment. Because performance measurement lies at the heart of any per- formance-improvement process, it is imperative that performance meas- ures be selected in a thoughtful and deliberate manner. Performance measures may be internally developed or adopted from a multitude of external resources. However, regardless of the source of performance measures, each measure should be considered against certain character- istics to help ensure a credible and beneficial measurement effort. Reliable measures accurately and consistently identify the events they were designed to identify across multiple healthcare settings. Valid meas- ures raise good questions about current processes and therefore underlie the identification of opportunities for improvement.
