BackgroundWe describe and evaluate the development and use of a Clinical Decision Support (CDS) intervention; an alert, in response to an identified medical error of overuse of a diagnostic laboratory test in a Computerized Physician Order Entry (CPOE) system. CPOE with embedded CDS has been shown to improve quality of care and reduce medical errors. CPOE can also improve resource utilization through more appropriate use of laboratory tests and diagnostic studies. Observational studies are necessary in order to understand how these technologies can be successfully employed by healthcare providers.MethodsThe error was identified by the Test Utilization Committee (TUC) in September, 2008 when they noticed critical care patients were being tested daily, and sometimes twice daily, for B-Type Natriuretic Peptide (BNP). Repeat and/or serial BNP testing is inappropriate for guiding the management of heart failure and may be clinically misleading. The CDS intervention consists of an expert rule that searches the system for a BNP lab value on the patient. If there is a value and the value is within the current hospital stay, an advisory is displayed to the ordering clinician. In order to isolate the impact of this intervention on unnecessary BNP testing we applied multiple regression analysis to the sample of 41,306 patient admissions with at least one BNP test at LVHN between January, 2008 and September, 2011.ResultsOur regression results suggest the CDS intervention reduced BNP orders by 21% relative to the mean. The financial impact of the rule was also significant. Multiplying by the direct supply cost of $28.04 per test, the intervention saved approximately $92,000 per year.ConclusionsThe use of alerts has great positive potential to improve care, but should be used judiciously and in the appropriate environment. While these savings may not be generalizable to other interventions, the experience at LVHN suggests that appropriately designed and carefully implemented CDS interventions can have a substantial impact on the efficiency of care provision.

The intensive care unit (ICU) waiting room is a dynamic place that influences the satisfaction of families of critically ill patients. Waiting-room comfort and amenities are important, because families often spend a great deal of nonvisiting time there. A quality improvement evaluation of the ICU waiting room at Lehigh Valley Hospital, Allentown, PA, was conducted. Methods included distribution of an 18-item family survey, ethnographic observations, interviews, and assessment of the physical environment. Findings suggest that the role of the receptionist and access to food and other services were important to families and influenced their assessment of the quality of services provided by the ICU.

Ethnographic methods can provide insights into patients' perceptions of quality of care. We used ethnographic methods to examine problems related to answering patient call lights on one inpatient unit in the hospital. Communication through call bells consisted of 3 interrelated components. These included answering the call bell, communicating the patient's request, and following through with the request. Results of this study provided a deeper understanding of the nuances of power and control embedded within the issue of patient-caregiver communication and empowered unit staff to find solutions to the call bell problem.
