OBJECTIVES To characterise the information needs of family doctors by collecting the questions they asked about patient care during consultations and to classify these in ways that would be useful to developers of knowledge bases. DESIGN Observational study in which investigators visited doctors for two half days and collected their questions. Taxonomies(More)
A large number of taxonomies are used to rate the quality of an individual study and the strength of a recommendation based on a body of evidence. We have developed a new grading scale that will be used by several family medicine and primary care journals (required or optional), with the goal of allowing readers to learn one taxonomy that will apply to many(More)
OBJECTIVE To describe the obstacles encountered when attempting to answer doctors' questions with evidence. DESIGN Qualitative study. SETTING General practices in Iowa. PARTICIPANTS 9 academic generalist doctors, 14 family doctors, and 2 medical librarians. MAIN OUTCOME MEASURE A taxonomy of obstacles encountered while searching for evidence based(More)
OBJECTIVE To develop a taxonomy of doctors' questions about patient care that could be used to help answer such questions. DESIGN Use of 295 questions asked by Oregon primary care doctors to modify previously developed taxonomy of 1101 clinical questions asked by Iowa family doctors. SETTING Primary care practices in Iowa and Oregon. PARTICIPANTS(More)
Delivery of excellent primary care-central to overall medical care-demands that providers have the necessary information when they give care. This paper, developed by the National Alliance for Primary Care Informatics, a collaborative group sponsored by a number of primary care societies, argues that providers' and patients' information and decision support(More)
OBJECTIVE To identify the most frequent obstacles preventing physicians from answering their patient-care questions and the most requested improvements to clinical information resources. DESIGN Qualitative analysis of questions asked by 48 randomly selected generalist physicians during ambulatory care. MEASUREMENTS Frequency of reported obstacles to(More)
Infectious mononucleosis should be suspected in patients 10 to 30 years of age who present with sore throat and significant fatigue, palatal petechiae, posterior cervical or auricular adenopathy, marked adenopathy, or inguinal adenopathy. An atypical lymphocytosis of at least 20 percent or atypical lymphocytosis of at least 10 percent plus lymphocytosis of(More)
Several taxonomies exist for rating individual studies and the strength of recommendations, making the analysis of evidence confusing for practitioners. A new grading scale-the Strength of Recommendation Taxonomy (SORT)-will be used by several family medicine and primary care journals (required or optional), allowing readers to learn 1 consistently applied(More)
Articles about primary care topics that measure patient-oriented outcomes (eg, morbidity, mortality, quality of life) should change practice, if the reported results are valid. We call these types of articles POEMs--Patient-Oriented Evidence that Matters. The extent and distribution of POEMs in the medical literature is unknown. We identified 85 medical(More)
BACKGROUND The success rate of cardiopulmonary resuscitation (CPR) varies with the patient population studied. Prearrest variables have been used to identify groups of patients with a particularly low rate of survival following CPR. The purpose of this study was to use the technique of meta-analysis to identify prearrest variables associated with a(More)
