American medicine is in the midst of a professional evolution driven by a refocusing of medicine's regard for the patient's viewpoint. Historically, medicine has been largely physician centered, but physicians have begun to incorporate patients' perspectives in ways that increasingly matter. Some call this shift "patient-centered" care. In support of the view that this refocusing reflects a broad professional shift, we describe the evolution to patient-centered care in many areas of medicine: patient care, health-related law, medical education, research, and quality assessment.

With increasing pressure to measure quality, patient-based assessments of medical care are becoming increasingly important. Patients offer a unique perspective for evaluating the nontechnical aspects of medical care. This study reviews the importance of utilizing patients' perceptions to measure quality of care in office settings. It also reviews the principles required to conduct a well done survey. The concept of patient perceptions differs from the more commonly measured concept of patient satisfaction, in that perceptions measure whether a patients' needs and expectations are met, in addition to satisfaction. One of the most accurate and efficient means of measuring patients' perceptions is through the use of surveys. As with all standardized data collection, creating and performing high quality surveys of patients' perceptions can be challenging. Valid and reliable patient survey data can enable practitioners to identify areas for improvement, and demonstrate to external reviewers the quality of care they provide to their patients.

OBJECTIVE: The In-Training Examination in Internal Medicine (ITE-IM) has been offered to internal medicine trainees annually since 1988 as an instrument for self-assessment. This report outlines the manner in which the test is prepared, reviews the results of annual examinations, and analyzes trends during the past 6 years. DESIGN: Results of each examination were reviewed with regard to the demographic characteristics of persons taking the test, their previous medical training, and their present program affiliations. RESULTS: Then number of residents participating in the ITE-IM has increased steadily over the past 6 years. In 1993, more than 12,000 residents from more than 90% of internal medicine training programs in the United States participated in the examination; the percentage of international medical school graduates taking the examination increased from 27% in 1988 to 47% in 1993. Statistical analyses of each examination have shown it to be reliable, internally consistent, and discriminating. Over the past 6 years, graduates of U.S. medical schools have scored consistently higher than those of international medical schools and schools of osteopathic medicine on all annual examinations. However, in 1993, for residents at all levels of training, the differences in scores between graduates of U.S. medical schools and graduates of international medical schools narrowed substantially. From 1988 to 1993, there has been a trend toward lower scores by every cohort on each subsequent examination. The decreases in scores are most pronounced for graduates of U.S. medical school and those of schools of osteopathic medicine. The lower scores may be caused by either an increased level of difficulty in the examination or decreased knowledge among examinees. CONCLUSIONS: The ITE-IM is a useful instrument to assess the knowledge base of residents and program directors with a reliable evaluation of themselves and their programs in comparison to their national peer groups. It also provides objective data to monitor trends over time in residents' scores and relates them to the changing demographic characteristics of trainees and to innovations in the clinical curricula of internal medicine training programs.

This study evaluates inter-author variability in knowledge base construction. Seven board-certified internists independently profiled "acute perinephric abscess", using as reference material a set of 109 peer-reviewed articles. Each participant created a list of findings associated with the disease, estimated the predictive value and sensitivity of each finding, and assessed the pertinence of each article for making each judgment. Agreement in finding selection was significantly different from chance: seven, six, and five participants selected the same finding 78.6, 9.8, and 1.6 times more often than predicted by chance. Findings with the highest sensitivity were most likely to be included by all participants. The selection of supporting evidence from the medical literature was significantly related to each physician's agreement with the majority. The study shows that, with appropriate guidance, physicians can reproducibly extract information from the medical literature, and thus established a foundation for multi-author knowledge base construction.
Dissatisfaction with the current internal medicine residency experience has led to proposals for various new curricula. Unfortunately, the more basic question of "What is a curriculum?" or more accurately, "What curriculum model is most appropriate for clinical training?" has remained largely unexamined. The dominant curriculum model, although valuable, may not be adequate for the task. In its place we propose an experimental model that is more congruent with the realities of graduate medical education.
