Obtaining clinical data on the appropriateness of medical care in community practice.

We sought the voluntary cooperation of a randomly selected sample of community physicians and hospitals in five states for a study of how appropriately they performed coronary angiography, carotid endarterectomy, and upper gastrointestinal tract endoscopy. Ninety percent of 913 sampled physicians (n = 819) consented to a review of up to 20 of their 1981 Medicare patients' records. These physicians represented seven different specialties and subspecialties and performed 4988 procedures, 92% of the desired sample. Only three of 230 hospitals did not participate. We attribute our method's success primarily to the formation of a network to connect the branches of the profession, respect for office and hospital practice routine, confidentiality, and the development of carefully designed medical record abstraction systems. We conclude that, with effort, cooperative research among disparate segments of the medical community can become a reality even if the topic studied is relatively sensitive.

How coronary angiography is used. Clinical determinants of appropriateness.

Using ratings of appropriateness derived from an expert physician panel, we measured how appropriately physicians in 1981 performed coronary angiography in a randomly selected, community-based sample of cases in the Medicare population. We studied large geographic areas (three sites) in three states, representing regions of high and low use. The high-use site had fewer procedures classified as appropriate (72%) than either low-use site (77% and 81%, respectively). Over all sites, 17% of procedures were classified as inappropriate. Patients in the high-use site were older, had less severe angina, and were less intensively medically treated than patients in either of the low-use sites. Patients without angina who had not undergone exercise testing constituted the most common subgroup of inappropriate cases. Although overall differences in appropriateness were not large, practice differences do exist. This analysis of practice differences among study sites provides the clinical basis for understanding the small, but significant, differences in the appropriateness of use of coronary angiography. The finding of 17% inappropriate use may be cause for concern.

The appropriateness of using a medical procedure. Is information in the medical record valid?

Understanding the clinical appropriateness of a procedure's use may be critical in explaining geographic variations in its use. Little is known, however, about whether data on appropriateness can be obtained from a medical record. A national panel of physicians formulated a list of 300 mutually exclusive, detailed clinical indications for performing coronary angiography. Using this list, we compared the reasons physicians perform coronary angiography as revealed in medical records with those given in interviews with the physicians who actually did the procedure. Thirty-five of 47 eligible billing entities (74%) from two Los Angeles Professional Standards Review Organization areas participated. These physicians practiced in 14 hospitals and accounted for 81% of all angiographies performed on Medicare patients in the two areas. Sixty-six records (approximately two per physician) were reviewed; physician interviews were conducted by two trained data collectors who were blinded to each other's results. Ninety-one percent agreement was reached on the specific indication for performing coronary angiography when information from the record review and interview was compared. We conclude that medical records yield valid information on why coronary angiography is performed and that they are a suitable source to use in judging the appropriateness of that use.

Derivation of clinical indications for carotid endarterectomy by an expert panel.

We used a two-round consensus panel method to derive and rate the appropriateness of comprehensive sets of detailed clinical indications for performing carotid endarterectomy. Before meeting, nine nationally influential physicians rated 675 indications; after review and discussion, they rated 864. The method did not force unanimity; our purposes were not only to encourage agreement but also to uncover areas of disagreement concerning the procedure's appropriate use. The panelists agreed on the level of appropriateness for 54 per cent of the final 864 indications and disagreed on 18 per cent. Ratings were reliably reproduced six to eight months after the completion of the process. The physicians' indications and ratings were consistent with those in the literature, and statistical analysis demonstrated that they followed logical clinical rationale. We conclude that consensus methods that do not force agreement can be used with panels of physicians to produce detailed, reliable, and valid indications. They can also identify medically controversial reasons for using a procedure that can serve as a starting point for a research agenda.

Educating physicians and treating patients in the ambulatory setting. Where are we going and how will we know when we arrive?

We evaluated 15 group practices in general internal medicine in university hospitals with regard to access to and quality of care, patients' satisfaction with that care, and quality of residency education provided. We used these data to speculate about potential changes in ambulatory care programs in university teaching hospitals. All 15 practices participated for 4 years. One third of their patient population had no medical insurance. Practice patients had twice as many chronic illnesses as did the general population, and two fifths of patients stayed at least 2 years in the practice. Few faculty members spent more than 14 hours weekly in the practices, and housestaff worked an average of 4 hours per week. Patient waiting times did not meet ideal standards, but patient satisfaction was higher than in a general population. Compliance with quality of care criteria was not exceptional; for example, 10% of eligible patients received an annual influenza vaccination. Housestaff assigned a relatively low ranking to their educational experience in the practices. We recommend the institution of additional experimental programs in ambulatory care and housestaff education to improve the quality of care in the ambulatory setting.

Providing primary general medical care in university hospitals: efficiency and cost.

Data on efficiency, costs, and profits of 15 internal medicine outpatient group practices in university hospitals were collected for 9 months from interviews, a time-motion study, observations, and reviews of bills. Charges for a follow-up visit were about 25% higher than Medicare's allowable charges, but differed threefold across practices. Physicians spent more than half their allocated patient care or supervision time in other activities and 14% of nursing time was used for direct patient care. Visits to second- and third-year residents cost one half of those to faculty. Faculty supervision of second- and third-year residents was limited; it was, on average, 2 minutes per follow-up visit. Despite these inefficiencies, bad debts, and educational costs, practices appeared to break even financially. We conclude it is financially feasible for university hospitals to provide primary care to disadvantaged populations.

Sufficiency of clinical literature on the appropriate uses of six medical and surgical procedures.

We reviewed the English-language clinical literature on carotid endarterectomy, cholecystectomy, upper gastrointestinal endoscopy, colonoscopy, coronary angiography and coronary artery bypass graft procedure to identify the appropriateness of using these procedures in 1981. Most of the 803 relevant articles and textbooks were published after 1975; about 10% of the 571 research studies were randomized, controlled trials, while two thirds were retrospective studies. Incomplete or contradictory information was available on the indications for and efficacy of using the procedures; almost no data were available on costs and use; data on complications failed to specify patients' symptoms or the relationship between complications and reasons for doing the procedure.

Variations in the use of medical and surgical services by the Medicare population.

We measured geographic differences in the use of medical and surgical services during 1981 by Medicare beneficiaries (age greater than or equal to 65) in 13 large areas of the United States. The average number of Medicare beneficiaries per site was 340,000. We found large and significant differences in the use of services provided by all medical and surgical specialties. Of 123 procedures studied, 67 showed at least threefold differences between sites with the highest and lowest rates of use. Use rates were not consistently high in one site, but rates for procedures used to diagnose and treat a specific disease varied together, as did alternative treatments for the same condition. These results cannot be explained by the actions of a small number of physicians. We do not know whether physicians in high-use areas performed too many procedures, whether physicians in low-use areas performed too few, or whether neither or both of these explanations are accurate. However, we do know that the differences are too large to ignore and that unless they are understood at a clinical level, uninformed policy decisions that have adverse effects on the health of the elderly may be made.

Evaluation of ambulatory care training by graduates of internal medicine residencies.

In 1984, 154 physicians who had completed residencies in internal medicine at 15 major teaching hospitals in 1982 evaluated their residency training in ambulatory care. A majority of the physicians would have liked more experience in practical areas related to career planning and office management, more input from subspecialties such as orthopedics and dermatology, greater knowledge about the management of psychosocial problems, and more information about exercise and nutrition. Although many physicians also wanted more time devoted to several other topics, less than 20 percent recommended spending less time on 26 of the 27 topics being evaluated. Since these recommendations are similar to those reported in evaluation studies published over the past 25 years, it appears that training programs in internal medicine have not been successful in restructuring their curricula to meet many of the needs of practicing physicians.

Physician ratings of appropriate indications for six medical and surgical procedures.

We convened three panels of physicians to rate the appropriateness of a large number of indications for performing a total of six medical and surgical procedures. The panels followed a modified Delphi process. Panelists separately assigned initial ratings, then met in Santa Monica, California where they received reports showing their initial ratings and the distribution of the other panelists ratings. They discussed the indications and revised the indications lists, then individually assigned final ratings. There was generally better agreement on the final ratings than on the initial ratings. Based on reasonable criteria for agreement and disagreement, and excluding one outlying procedure, the panelists agreed on ratings for 42 to 56 per cent of the indications, and disagreed on 11 to 29 per cent.

Physician and patient satisfaction as factors related to the organization of internal medicine group practices.

The present study compares patient satisfaction scores with job satisfaction scores of the physicians providing their care in 16 general internal medicine teaching hospital group practices. Practice sites with more satisfied patients were also more likely to have more satisfied housestaff and faculty physicians. Additionally, higher satisfaction scores for both physician groups and patients were consistently associated with a greater percentage of patients experiencing continuity of care, lower patient no-show rates, more efficient use of ancillary staff in providing direct patient care, and more reasonable charges for a routine follow-up visit. These findings suggest that improving physician and patient satisfaction may have economic as well as psychological and social benefits.

General medical care and the education of internists in university hospitals. An evaluation of the teaching hospital general medicine group practice program.

Fifteen general internal medicine group practices in university teaching hospitals were studied to evaluate their primary care services and education. Data were collected over 9 months from physicians, patients, and medical records, and by observation. All institutions had closed their general medical clinics. Many patients being treated in group practices were very sick; 57% had hypertension; 21% were diabetic; and 45% could not work. Most were satisfied with their care. Care for acute problems from a health care provider in the practice was available quickly; regular physicians were harder to see. House staff and faculty spent little time in the practices. Few practices used teams; most used traditional attending and house staff models. Practice physicians could not easily determine when patients were seen in the institution's emergency department or were hospitalized. Quality of care standards were not uniformly met. Finally, the structure of academic centers appeared to inhibit the practices' performance, suggesting a need for further appraisal of relationships between university hospitals and their ambulatory care units.

Consensus methods: characteristics and guidelines for use.

Consensus methods are being used increasingly to solve problems in medicine and health. Their main purpose is to define levels of agreement on controversial subjects. Advocates suggest that, when properly employed, consensus strategies can create structured environments in which experts are given the best available information, allowing their solutions to problems to be more justifiable and credible than otherwise. This paper surveys the characteristics of several major methods (Delphi, Nominal Group, and models developed by the National Institutes of Health and Glaser) and provides guidelines for those who want to use the techniques. Among the concerns these guidelines address are selecting problems, choosing members for consensus panels, specifying acceptable levels of agreement, properly using empirical data, obtaining professional and political support, and disseminating results.

Studies in geriatric education: II. educational materials and programs.

There has recently been an increase in educational programs and materials in geriatrics, but their quality and content have not been adequately assessed. This study concerns important objectives and core contents in geriatric education, with a review of training programs, books, and audiovisual materials. Specific areas of need for printed and audiovisual materials are identified. Medical student and graduate level programs were found to address relatively few objectives. Geriatric fellowship programs, although having more extensive coverage, had some notable deficiencies. This information may be of use to those conducting training programs or preparing educational material in geriatrics.

Studies in geriatric education: I Developing educational objectives.

This study reports on the development of a comprehensive set of objectives for the education of undergraduates, graduates, and fellows in geriatric medicine. The objectives were derived from reviews of available educational materials and programs, and their significance was validated through consensus techniques that included over 100 workers with special expertise in geriatrics and gerontology from the United States. Canada, and the United Kingdom. A related and supplementary investigation, which also used consensus methods, uncovered ten general and disease-specific objectives considered to be essential outcomes of the education of geriatric fellows. Academic departments and specialty and subspecialty organizations should find the total set of objectives useful for planning and evaluating educational programs in geriatrics.
