Access to community-based medical services and number of hospitalizations among patients with HIV disease: are they related?

To assess whether better access to community-based outpatient medical services was associated with fewer HIV-related hospitalizations, we studied 217 patients hospitalized at seven southern California hospitals. During hospital admission, patients completed an interview that included one item about the reported difficulty or ease of access to community-based medical services prior to their first hospitalization for HIV-related illness. After discharge, medical records were abstracted for data on prior hospitalizations. CD4 counts, and illness severity. About one-half of patients reported that medical services were readily accessible. Medical records revealed that since the time of HIV infection 49% had two or more total hospitalizations (mean = 2. SD = 2). In multiple logistic regression analysis, better reported access to services was significantly associated with not having been hospitalized (vs. having been hospitalized) over the same time period (OR = 0.73, 95% CI = 0.55-0.97), controlling for CD4 count, illness severity, duration of diagnosed HIV infection, having a regular source of care, type of hospital care, insurance coverage, and other patient characteristics. Improving access to community-based medical services for ambulatory HIV-infected patients may help to avert costly hospital care. Prospective studies are needed to assess whether a causal relationship between greater community-based access and reduced hospitalizations exists and, if so, whether community-based services may be cost-effective substitutes for hospital HIV care.

Indicators of oral health in diverse ethnic and age groups: findings from the International Collaborative Study of Oral Health Outcomes (ICS-II) USA research locations.

Racial-ethnic group differences are assessed using a standardized set of oral health indicators, as well as various predisposing, enabling and need characteristics collected in the International Collaborative Study of Oral Health Outcomes (ICS-II) USA research locations. The unique data set contains comparable data on African-American, Native American, Hispanic, primarily Mexican-American, and White adults. Age group differences in oral health indicators are also compared in two adult age cohorts (35-44 and 65-74 years). Since data were collected from geographically diverse regions of the United States, differences in oral health indicators are considered within the context of different dental care delivery systems and external environments. Results indicate that the gap in oral health between Whites and ethnic minority groups is pervasive across research locations and age cohorts. Variation in regional dental care delivery systems and the varying effects of race-ethnicity and age cohort suggest that alternative health promotion strategies will be needed for improving oral health in diverse populations.

An exploratory analysis of market-based, physician-organization arrangements.

The growth of physician-organization arrangements (e.g., PHOs, MSOs) by physician specialty groups and delivery organizations is widely acknowledged. Yet, little is known about these new organizational forms. This paper presents a descriptive analysis of physician-organization arrangements (POAs) using survey data obtained from 79 organizations. The analysis examines the extent to which healthcare delivery organizations are engaged in the development of POAs, the number of physicians involved in POAs, and the decision-making control and strategies associated with POAs. These attributes are examined for the sample as a whole and relative to the institutional and market conditions facing study participants. Results are discussed in terms of their implications for health services managers.

Symbiotic relationships of quality of life, health services research and other health research.

Clinical biomedical research, the traditional research orientation of quality of life (QOL) researchers, is chiefly concerned with disease processes and assessing the impact of therapeutic interventions on improving health status and QOL outcomes. This paper suggests, however, that the biomedical paradigm limits utility of QOL research findings in terms of its ability to shape health policy and improve health-related QOL in populations at risk. This paper proposes that health services research (HSR) and other health research paradigms can be used to assess QOL from multiple perspectives. HSR and QOL research can be mutually beneficial. The models for understanding health services utilized in HSR may assist in defining major determinants of QOL and the interaction of QOL with its environment. Conversely, QOL measures may be used to establish the relevance of HSR to people's well-being. The paper first defines the domain of HSR and the domain of quality of life. In order to understand their relationship, we consider what a model or paradigm for each might be, and how they would overlap. Finally, a merging of conceptual frameworks is proposed, linking QOL research to HSR and other health research. Ultimately, expanding the QOL paradigm beyond the biomedical model will promote two objectives. First, it will permit research findings to contribute more fully to shaping national health policy by considering the broader community and the delivery system factors which influence QOL. Second, researchers will be more aware of a broader range of factors affecting patients and will incorporate this in their research.

Trends in hospital/physician relationships.

Findings from two surveys of all physicians in Pima County, Arizona, in 1985 and 1990 to determine the trajectory of hospital/physician relationships suggest that conflicts have increased in almost all areas. Physicians report the greatest number of and increase in conflicts in traditional problem areas such as the quality of nursing and response to equipment requests. They report a smaller increase in conflicts relating to the new competitive marketplace, including hospital efforts to influence medical practice. Both types of problems are most prevalent among younger physicians. The new marketplace thus appears to exacerbate traditional hospital/physician conflicts more than it generates new areas of contention.

National Study of Internal Medicine Manpower: XIX. Trends in internal medicine residency training programs.

The National Study of Internal Medicine Manpower (NaSIMM) reports on the results of its 1989-1990 census of residency programs. The results are integrated into an organizational model identifying inputs, process, outputs, and environment of medical training programs. The number of residents entering internal medicine continues to grow at a relatively rapid pace. This growth is largely accounted for by foreign citizens who are graduates of foreign medical schools (AFMGs). Residents are spending an increasing proportion of their time in ambulatory care settings, but, thus far, this ambulatory care training has occurred primarily in hospital clinics and emergency rooms. The proportion of a program's residents entering general internal medicine was found in a multiple regression analysis to be negatively associated with the number of subspecialty programs located in the training hospital, the percent of AFMG residents in the program, and the presence of a preliminary track in the program.

National Study of Internal Medicine Manpower. XVIII: Subspecialty fellowships with a special look at hematology and oncology, 1988-1989.

OBJECTIVE: To determine the number and distribution of internists in subspecialty training and compare with data collected since 1976; to determine the distribution of activity of subspecialty fellows; and to focus on hematology and oncology. DESIGN: Repeated mail survey with telephone follow-up. PARTICIPANTS: All directors of subspecialty training programs in internal medicine in the United States. RESULTS: The 1988-1989 census identified 7530 fellows in training, 55 more than in 1987-1988. There are 24 more first-year fellows. Reports on the activities of subspecialty fellows show that, overall, 53% of fellows' time is spent in direct patient care, 20% on basic research, 15% on patient-related research, and 12% in teaching. CONCLUSIONS: The number of internists entering subspecialty training has risen at a considerably slower rate in the last 5 years compared with the 5 years before that. The length of subspecialty training has increased significantly since 1976. There has been a shift in subspecialty choice from hematology to oncology and toward joint programs offering both subspecialties.

National Study of Internal Medicine Manpower: XVII. Changes in the characteristics of internal medicine residents and their training programs, 1988-1989.

The National Study of Internal Medicine Manpower (NaSimm) has been surveying program directors of internal medicine about their programs and residents for 13 years. The 1988-1989 survey results, when compared with the results for 1987-1988, show an increase in both the number of residency positions offered in internal medicine and the number of residents in internal medicine programs. Although the proportion of graduates from U.S. medical schools who choose internal medicine is not changing (34%), the proportion of U.S. medical school graduates who continue training in internal medicine after their first year is decreasing. The composition of the residents in internal medicine by medical school graduated is also changing. Almost 25% of the first-year residents (R1s) in internal medicine are now graduates of foreign medical schools (FMGs) compared with 14% in 1976. The proportion of first-year female residents in internal medicine has increased to 30%, whereas the proportion of both first-year blacks and Hispanics has remained constant at 5% each. In nearly 25% (109 of 440) of the residency programs, more than 50% of the R1s are FMGs. Hispanics, Asians, and blacks were found to be over-represented in the programs training larger proportions of FMGs. This over-representation is attributable, in part, to the fact that Hispanics and Asians may be FMGs. Training issues of concern to program directors continue to be the provision of ambulatory and primary care experiences and the scheduling of nights on call. The survey results show that many residency program directors have reported a reduction in the number of nights on call and an increase in the amount of time residents spend in ambulatory training.

The effect of hospital control strategies on physician satisfaction and physician-hospital conflict.

This article examines several strategies that hospitals use to control their medical staffs. Such strategies include placing physicians on salary, developing exclusive hospital affiliations with physicians, and involving physicians in decision-making bodies. Using regression techniques, we investigate which hospitals are more likely to utilize these strategies and whether such strategies are effective in promoting physician-hospital integration. Contrary to our expectations, corporate hospital structures (e.g., for-profit hospitals, membership in multihospital systems) generally do not employ these strategies more often and oftentimes employ them less. There is also little evidence that control strategies are effective levers for increasing physician satisfaction or decreasing physician-hospital conflict. We suggest that control strategies are useful for purposes other than promoting physician-hospital integration. Finally, hospital ownership appears to exert the biggest effect on physician satisfaction and conflict.

National Study of Internal Medicine Manpower: XVI. Subspecialty fellowship programs, 1988 update.

Much of the debate about medical manpower during the 1980s has focused on the growing number of medical subspecialists. We examined the number of subspecialty fellows since 1976, paying particular attention to data collected in the 1987-1988 academic year. The number of fellows in subspecialty training at a given time has increased by 27% since 1976; however, much of this increase is due to the increased length of the training programs. The number of first-year fellows has increased only 7% since 1976. Growth in the number of fellowships has varied by subspecialty. The number of fellowships in geriatrics, critical care, and general internal medicine has increased dramatically. Additionally, the traditional subspecialties-cardiology, pulmonary disease, gastroenterology, infectious diseases, rheumatology, and allergy-immunology-have all grown to some extent. Program directors in all subspecialties anticipate continued growth in the coming years.

National Study of Internal Medicine Manpower: XV. A decade of change in residency training in internal medicine.

We report on trends in the characteristics of residency training programs in internal medicine from 1976 to 1988 and make some comparisons with other specialties. Internal medicine is faring less well in the residency match compared with other specialties than it did 10 years ago. It has also increased the number of residency positions offered more than other major specialties. A sizable proportion of first-year residency positions in internal medicine are not filled through the Match. Foreign medical graduates account for almost 50% of the first-year resident (R1) positions filled outside the Match. Programs most dependent on foreign medical graduates are in hospitals with limited medical school affiliation, smaller size, operated by churches or the Veterans Administration, and located in eastern states and large metropolitan areas. Despite concerns about quality and oversupply, almost 50% of the program directors expected to increase the size of their programs in 1988-1990. Residents are not being scheduled for fewer hours per week than they were 12 years ago but they are being scheduled for fewer nights. No trends were noted toward increased ambulatory care training sites away from the hospital campus.

The impact of corporate structures on physician inclusion and participation.

This study examines the impact of corporate arrangements on the hospital-physician relationship. Specifically, it investigates the effects of for-profit ownership and membership in a multihospital system on physician inclusion (salaried employment, hospital-based practice) and participation (involvement in governance and management). Contrary to common perceptions and several hypotheses drawn from the literature, corporate arrangements are associated with low physician inclusion and high participation. There is no indication that corporatization of healthcare restricts the physician's freedom of movement or decision-making role. It is instead argued that health care corporations do just the opposite in order to please physicians, promote physician welfare, and to gain legitimacy.

National Study of Internal Medicine Manpower. XIV: Patterns of residency and fellowship over time, 1987 update.

In response to concerns among internists following the 1987 internal medicine match, this report compares internal medicine trainees with those in other specialties since 1972, describes their paths through the internal medicine "pipeline," and documents their distribution and continuation rates in residency and subspecialty fellowship programs. It is based on the National Study of Internal Medicine Manpower, 1987-1988. Between 1972 and 1986 the number of trainees in internal medicine doubled, and the percentage of trainees in internal medicine grew from 20% to 25%, while the percentage in surgical specialties declined from 28% to 19%. The numbers of women and foreign medical school graduates training in internal medicine have continued to increase, but minority representation has stabilized. Women and minorities have lower continuation rates into fellowships, and distinctive patterns of subspecialization are found among women, minorities, and foreign medical school graduates.
