Abstract

BACKGROUND: This article describes how the Pharmacy and Therapeutics Committee at Lutheran General Hospital (Park Ridge, IL) formed a continuous quality improvement (CQI) team and used statistical process control (SPC) tools to assess efforts to reduce medication errors. METHODS: The team worked with the nursing quality council to develop an intravenous (IV) training module for nurses that effectively decreased the average number of errors per month. The article illustrates the effective use of a run chart, a Pareto chart, and two types of control charts (p-charts and np-charts) to identify an opportunity for improvement, develop an improvement strategy, and measure the effectiveness of the intervention. CONCLUSION: Lessons learned from this case include the following: 1) Although run charts can be used as a preliminary step to determine whether a process has common-cause or special-cause variation, p-charts or np-charts are more precise tools for identifying special causes and for measuring the impact of interventions; 2) Pareto charts are useful for focusing on the areas of a process that will have the greatest impact in achieving the desired results; 3) When p-charts show little variation in control limits from month to month, the np-chart is an appropriate and more user-friendly alternative; and 4) In addition to validating the overall effectiveness of the intervention, the np-chart also helped to identify where the intervention failed.

Community hospitals--the place of local service provision in a modernising NHS: an integrative thematic literature review.

BACKGROUND: Recent developments within the United Kingdom's (UK) health care system have re-awakened interest in community hospitals (CHs) and their role in the provision of health care. This integrative literature review sought to identify and assess the current evidence base for CHs. METHODS: A range of electronic reference databases were searched from January 1984 to either December 2004 or February 2005: Medline, Embase, Web of Knowledge, BNI, CINAHL, HMIC, ASSIA, PsychInfo, SIGLE, Dissertation Abstracts, Cochrane Library, Kings Fund website, using both keywords and text words. Thematic analysis identified recurrent themes across the literature; narrative analyses were written for each theme, identifying unifying concepts and discrepant issues. RESULTS: The search strategy identified over 16,000 international references. We included papers of any study design focussing on hospitals in which care was led principally by general practitioners or nurses. Papers from developing countries were excluded. A review of titles revealed 641 potentially relevant references; abstract appraisal identified 161 references for review. During data extraction, a further 48 papers were excluded, leaving 113 papers in the final review. The most common methodological approaches were cross-sectional/descriptive studies, commentaries and expert opinion. There were few experimental studies, systematic reviews, economic studies or studies that reported on longer-term outcomes. The key themes identified were origin and location of CHs; their place in the continuum of care; services provided; effectiveness, efficiency and equity of CHs; and views of patients and staff. In general, there was a lack of robust evidence for the role of CHs, which is partly due to the ad hoc nature of their development and lack of clear strategic vision for their future. Evidence for the effectiveness and efficiency of the services provided was limited. Most people admitted to CHs appeared to be older, suggesting that admittance to CHs was age-related rather than condition-related. CONCLUSION: Overall the literature surveyed was long on opinion and short of robust studies on CHs. While lack of evidence on CHs does not imply lack of effect, there is an urgent need to develop a research agenda that addresses the key issues of health care delivery in the CH setting.
