Large databases can be a rich source of clinical and administrative information on broad populations. These datasets are characterized by demographic and clinical data for over 1000 patients from multiple institutions. Since they are often collected and funded for other purposes, their use for secondary analysis increases their utility at relatively low costs. Advantages of large databases as a source include the very large numbers of available patients and their related medical information. Disadvantages include lack of detailed clinical information and absence of causal descriptions.
Qigong is a mind-body integrative exercise or intervention from traditional Chinese medicine used to prevent and cure ailments, to improve health and energy levels through regular practice. The aim of this systematic review is to summarize and critically evaluate the effectiveness of qigong used as a stand-alone or additional therapy in cancer care.
OBJECTIVE: Acupuncture is frequently advocated as an effective treatment of dental pain. The question whether or not it is effective for this indication remains controversial. The aim of this systematic review therefore was to assess the effectiveness of acupuncture in dental pain. DATA SOURCES: Four electronic databases were searched: Medline, Embase, CISCOM, and the Cochrane Library. Only controlled trials were included in this review. DATA EXTRACTION: Information was extracted from included studies and entered on standard forms independently by both authors.
OBJECTIVE: Traditional Chinese medicine (TCM) is a scientific discipline, which develops the related theories from the long-term clinical practices. The large-scale clinical data are the core empirical knowledge source for TCM research. This paper introduces a clinical data warehouse (CDW) system, which incorporates the structured electronic medical record (SEMR) data for medical knowledge discovery and TCM clinical decision support (CDS).

OBJECTIVES: To review systematically the evidence on the performance of diagnostic tests used to identify infection in diabetic foot ulcers (DFUs) and of interventions to treat infected DFUs. To use estimates derived from the systematic reviews to create a decision analytic model in order to identify the most effective method of diagnosing and treating infection and to identify areas of research that would lead to large reductions in clinical uncertainty. DATA SOURCES: Electronic databases covering period from inception of the database to November 2002.

BACKGROUND AND OBJECTIVES: The Comprehensive Dialysis Study (CDS) aimed to understand factors contributing to physical, functional, and nutritional health status among patients starting dialysis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: A phone interview survey was conducted with patients from a geographically stratified national random sample of dialysis units, and quarterly serum samples were obtained for patients at a preidentified subset of units.
Collaboration provides a unique opportunity for a variety of people and organizations to promote faith community nursing. With emphasis on holistic nursing, stewardship, and interpreting the dialogue between faith and health, educated nurses acting as health educators, planners, and counselors can aid in meeting the health needs and in promoting the well-being of their faith communities.
The BEACH (Bettering the Evaluation and Care of Health) program, a continuous national study of general practice, began in April 1998 and is now in its eighth year. More than 7500 GPs have participated to date (about one-third of the total workforce) and data are available for about 750,000 encounters. The following overview is designed to disseminate key findings from BEACH, to publicize the annual report, and as a public expression of gratitude to the GP participants without whose generous contribution this study would not be possible.
Approximately 10% of people have O-negative blood. Because it can be transfused into almost anyone, hospitals particularly value such blood. We use this fact, together with the assumption that blood types are exogenously assigned by nature, to design an empirical inquiry into altruism. We also investigate the timing of donations, especially focussing on the behaviour of new and established donors. We show that O-negative blood donors donate no more often than other people. Thus individuals apparently do not exhibit pure altruism.

Research data repositories (RDRs) are data storage entities where data can be submitted, stored, and subsequently accessed for purposes beyond the original intent. There is little information relating to non-biological RDRs, nor considerations regarding pediatric data storage and re-use. We examined parent perspectives on pediatric, non-biological RDRs. Qualitative, descriptive methods including both interviews and focus groups were used. Purposive sampling of adult participants in two provincial birth cohorts yielded 19 interviewees and 18 focus group participants (4 groups).
