A threat to the public health workforce: evidence from trends in preventive medicine certification and training

Evidence of a growing need for preventive medicine specialists is the congruence between needed competencies for practice in the current health care environment, as identified by the Council on Graduate Medical Education (COGME) and in other national reports, and the core competencies of preventive medicine residents. The total number of certified specialists in preventive medicine is 6091. The proportion of self-designated preventive medicine specialists among all U.S. physicians is on the decline and the greatest decline has been among those in public health (PH) and general preventive medicine (GPM). In addition, the total number of preventive medicine residents is on the decline, and the decline has been greatest among those training in PH and combined PH/GPM. One of the reasons for this decline has been inadequate funding due to the absence of Medicare graduate medical education (GME) financing for population-based vs. individual patient care services and meager and diminishing Title VII support. A paucity of faculty is apparent in medical schools with residency training and board certification in preventive medicine. Several actions may help reverse this trend and assure adequate numbers of preventive medicine specialists: expansion of Title VII to increase the number of residents receiving stipends and tuition, adding infrastructure support for faculty development and funding of demonstration projects in distance learning and in joint generalist/ preventive medicine residency training. Medicare GME reform should include recognition of population-based services and inclusion of preventive medicine residencies in provisions for "nonhospital-based" training and in up-weighting methodologies for primary care training. Expansion of Veterans Affairs, National Institute for Occupational Safety and Health, and Department of Defense support is also needed as is attention to resident debt reduction.     

Who teaches residents about the prevention and treatment of substance use disorders? A national survey.

BACKGROUND: Studies indicate that physicians are poorly prepared to identify and treat tobacco, alcohol, and drug use disorders. Several faculty development programs have been created to increase the number of residency teaching faculty with expertise in this area. There is limited information, however, on those who currently teach residents about these problems and whether there is a need for additional faculty development programs. METHODS: We conducted a 2-stage national survey of faculty who teach residents about substance use problems. First, residency directors from 7 specialties (family medicine, psychiatry, internal medicine, pediatrics, obstetrics and gynecology, emergency medicine, and osteopathy) responded to a mailed questionnaire asking them to identify faculty who teach residents about substance use disorders. Second, those identified were contacted and asked to participate in a telephone interview. RESULTS: Of 1293 faculty identified by the residency directors, 769 participated in a research interview. Most of these teachers were full-time physician faculty, men, white, and based in departments of family medicine or psychiatry. Teaching was primarily conducted in hospitals, general outpatient clinics, and classrooms rather than alcohol and drug treatment programs. Less than 10% of the faculty performed clinical work in alcohol and drug treatment programs, and only 19% were certified addiction specialists. The respondents reported a definite need for additional development programs for themselves and other residency teaching faculty. CONCLUSIONS: We suggest a modest increase in the number of faculty who teach residents about substance abuse disorders, and the creation of additional faculty development programs.     

A contractual model for accountability and financial stability in a community-based family practice residency

A contractual model is described that defines the relationship between the hospital and the Department of Family Practice. The model provides institutions supporting graduate training in family practice with a method that is accountable and cost effective. Application of this model at a community hospital over a five-year period is presented. The model resulted in expansion of the family practice residency, increased faculty numbers, increased income for the faculty, and control of the institution's cost of graduate medical education.     

Resource requirements for teaching continuity in primary care: contrasts between a graduate and an undergraduate program

Two similar primary care training programs for family practice residents and for medical students are compared to find differences and similarities in costs and the use of certain nonmonetary resources. Both programs emphasize long-term continuity, and trainees in both programs average two half-days per week at ambulatory care practice sites. Comparisons of the resource requirements of teaching high-continuity primary care curriculum segments between graduate and undergraduate programs will help determine where scarce medical teaching resources can be most beneficially used. It is hypothesized that there would be lower faculty costs, higher auxiliary staff and space requirements, and larger patient panel requirements for the residency program than for the undergraduate program. Extent of these differences could not be predicted. In the residency program, faculty costs were one quarter of total expenses and in the undergraduate program they were half of the program expenses. The residency recouped 81 percent of expenses from practice revenues while the undergraduate program recouped only 59 percent. The residency program averaged 814 visits per trainee during one year; the undergraduate program had only 268 visits per student.     

Stage of cancer at diagnosis for Medicare HMO and fee-for-service enrollees.

OBJECTIVES. Health maintenance organizations (HMOs) with Medicare contracts often provide cancer screening and preventive services not covered under fee-for-service. This study compared cancer patients in HMOs and fee-for-service on stage at diagnosis. METHODS. The study examined stage at diagnosis for aged Medicare enrollees in HMOs and fee-for-service, using information from the Surveillance, Epidemiology, and End Results program, linked with Medicare enrollment files. Twelve cancer sites were investigated, and demographics, area of residence, year of diagnosis (1985 to 1989), and education at the census tract level were controlled. RESULTS. HMO enrollees were diagnosed at earlier stages for cancers of the female breast, cervix, colon, and melanomas and at later stages for stomach cancer. There were no differences for cancers of the prostate, rectum, buccal cavity and pharynx, bladder, uterus, kidney, and ovary. HMO effects were strongest in areas with large, mature HMOs. CONCLUSIONS. Compared with fee-for-service enrollees, HMO enrollees were diagnosed at earlier stages for cancer sites for which effective screening services are available. The earlier detection of certain cancers among HMO enrollees may result from coverage of screening services and, perhaps, promotion by HMOs of such services.     

PMD6 Chronic Care Costs of New Medicare HMO Enrollees: Implications for Disease Management

Cost-effective care for chronic conditions is a growing concern of health plans enrolling increasing numbers of the elderly and disabled under Medicare risk contracts. This study provides evidence of the prevalence, patterns of care, and costs of chronic illnesses among new Medicare HMO enrollees. The results provide a foundation for estimates of the cost-effectiveness of drug therapy and care management programs that serve this group.
METHODS: We used national Medicare claims data to examine chronic care services and associated costs for a sample of 19,084 beneficiaries who enrolled in an HMO in 1995. We constructed three measures of cost: the total Medicare-covered cost, the cost of medical claims with the chronic condition coded as a diagnosis, and the regression-estimated effect of the chronic condition on cost.
RESULTS: 58% of the new Medicare HMO enrollees in our sample were treated for at least one of the selected chronic conditions in the six months before enrollment. One-third of the new enrollees had multiple conditions represented by diagnoses in more than one of eighteen chronic-condition groups. Persons with chronic conditions accounted for 93% of pre-enrollment Medicare costs among new HMO enrollees. Per 1,000 enrollees, pre-enrollment Medicare costs were greatest for those with hypertensive disease, coronary heart disease, heart failure, and diabetes.
CONCLUSIONS: The concentration of utilization and costs in those with chronic conditions suggests that appropriate drug therapy and care management for those with chronic conditions should be a top priority for HMOs with Medicare risk contracts. These estimates of prevalence suggest a need for HMOs to screen new Medicare HMO enrollees for chronic conditions immediately upon enrollment to ensure continuity of care.     

Success strategies for departments of family medicine.

Strong departments of family medicine in academic medical centers help assure the future scope and quality of family practice patient care, the ongoing evolution of family medicine as a scholarly discipline, and a continued flow of qualified medical school graduates into family practice residency programs and eventually into practice. This report presents key strategies of six successful departments of family medicine and describes the methods and skills considered important by the leaders of these departments. Common themes that emerge are (1) recruit and mentor the best faculty, (2) build a reputation for clinical excellence of faculty and residents, (3) become part of schoolwide curriculum activities, (4) establish a scholarly presence, and (5) develop networks of support.     

Medicare graduate medical education funding and rural hospitals

To assess the importance of medical residents to rural hospitals, and to predict the possible effect of reductions in Medicare graduate medical education (GME) payments, data from Medicare hospital cost reports and from a telephone survey of rural hospitals with residency programs are analyzed. In prospective payment system year 11, 70 rural hospitals received more than $80 million in Medicare GME payments. The presence of rural training programs enhanced staff physician recruitment and retention and led to increased numbers of physicians settling in communities surrounding the facilities. Many survey respondents felt that elimination of GME funds would results in downsizing or outright elimination of their training programs. The results support the contention that rural training programs are important to hospitals and their surrounding communities and provide an essential component of the physician supply pipeline to rural areas.     

Current Status of Nutrition Training in Graduate Medical Education From a Survey of Residency Program Directors

Introduction: Nutrition leaders surmised graduate medical nutrition education was not well addressed because most medical and surgical specialties have insufficient resources to teach current nutrition practice. A needs assessment survey was constructed to determine resources and commitment for nutrition education from U.S. graduate medical educators to address this problem. Methods: An online survey of 36 questions was sent to 495 Accreditation Council for Graduate Medical Education (ACGME) Program Directors in anesthesia, family medicine, internal medicine, pediatrics, obstetrics/gynecology, and general surgery. Demographics, resources, and open‐ended questions were included. There was a 14% response rate (72 programs), consistent with similar studies on the topic. Results: Most (80%) of the program directors responding were from primary care programs, the rest surgical (17%) or anesthesia (3%). Program directors themselves lacked knowledge of nutrition. While some form of nutrition education was provided at 78% of programs, only 26% had a formal curriculum and physicians served as faculty at only 53%. Sixteen programs had no identifiable expert in nutrition and 10 programs stated that no nutrition training was provided. Training was variable, ranging from an hour of lecture to a month‐long rotation. Seventy‐seven percent of program directors stated that the required educational goals in nutrition were not met. The majority felt an advanced course in clinical nutrition should be required of residents now or in the future. Conclusions: Nutrition education in current graduate medical education is poor. Most programs lack the expertise or time commitment to teach a formal course but recognize the need to meet educational requirements. A broad‐based, diverse universal program is needed for training in nutrition during residency.     

United Health Care of North Carolina

Physicians. While many of the rural physicians interviewed in North Carolina would prefer not to deal with HMOs at all, they are generally positive about their relationships with United Healthcare of North Carolina. These physicians chose to contract with the HMO to obtain new patients and to retain existing patients. They are satisfied that their participation has accomplished these goals. Their reimbursement arrangements are easy to understand, and most view the payment amounts as satisfactory. The physicians regard the size of the HMOs provider network and the open-access structure of the HMO as positive features that allow them to make referrals without the restrictions imposed by some other HMOs. To date, participation in United Healthcare of North Carolina has imposed few burdens on rural physicians. They are reimbursed on a fee-for-service basis, and their financial risk has been limited. They do not perceive that the HMO has had a significant impact on the way they practice medicine. This situation may change in the future if enrollees from United Healthcare of North Carolina and other HMOs constitute a greater proportion of their practices and if these HMOs move toward capitated reimbursement. The attitudes of rural physicians toward United Healthcare of North Carolina also may change if the HMO attempts to more actively manage the care provided to its enrollees. United Healthcare of North Carolina plans to eliminate physician risk sharing (in the form of withholds) and replace it with bonus payments. As one HMO executive said, the plan wants to “put incentives where they belong.” If rewarding good performance instead of punishing poor performance yields intended consequences, it may provide United Healthcare of North Carolina with a competitive advantage in rural areas. First, because such a change offers an opportunity to augment a physician's income instead of diminishing it, physicians might prefer to contract with the HMO rather than with other HMOs. Second, because bonus payments depend on performance, United Healthcare of North Carolina providers may produce outcomes that allow reductions in premium prices or expansions of benefits compared with the HMOs competitors. Hospitals. Rural hospitals cited similar motivations (attracting and retaining business) for participating in United Healthcare of North Carolina and similar levels of satisfaction with their relationships. In their experiences, the HMO has been fair in its negotiations and reimbursement. Although they contract with multiple HMOs, these rural hospitals do not perceive that HMO participation has had a significant impact on hospital operations. Because these hospitals, like many rural hospitals, rely heavily on Medicare (and, to a lesser degree, on Medicaid) as revenue sources, the future impact of managed care on their operations will depend in large part on the extent to which significant proportions of their Medicare and Medicaid patients enroll in HMOs.     

Enrollee health status under Medicare risk contracts: an analysis of mortality rates.

Previous studies comparing the health status of Medicare beneficiaries enrolled under HMO risk contracts to that of Medicare beneficiaries in fee-for-service (FFS) have generally focused on demonstration projects conducted before 1985. This study examines mortality rates in 1987 for approximately 1 million aged Medicare beneficiaries enrolled in 108 HMOs. We estimated adjusted mortality ratios (AMR) for each HMO and across all HMOs, by dividing the actual number of deaths among HMO enrollees by the "expected" number of deaths. The expected number of deaths was based on death rates among local FFS populations, adjusting for age, sex, Medicaid buy-in status, and institutional status. The AMR for all HMO enrollees pooled together was 0.80. For persons newly enrolled in 1987, the AMR was 0.69; in general, AMRs were higher for beneficiaries who had been enrolled for longer periods of time. Among individual HMOs, none exhibited an AMR substantially above 1.00. Regression analysis indicated lower AMRs for staff model HMOs than for either IPA or group models. Low mortality among Medicare HMO enrollees is consistent with favorable selection or with improvements in the health status of enrollees due to better access or quality of care in HMOs. In either case, health status differences between HMO enrollees and FFS beneficiaries have implications for the appropriateness of Medicare's Adjusted Average Per Capita Cost (AAPCC) payment formula for HMOs.     

Utilization of allied health personnel in HMOs

Health Maintenance Organizations (HMOs) have become a significant component of the health care delivery system and thus provide employment opportunities for allied health professionals. This study investigated the utilization of selected allied health services and personnel in a national sample of HMO settings. Significant utilization of allied health services were reported both through provision of services in-house and through contractual arrangements. Smaller HMOs tended to use several allied health services in-house, while larger HMOs used both in-house and contractual services. Younger HMOs tended to utilize contractual arrangements while older HMOs utilized in-house services. Staff and group HMOs tended to have the highest utilization of health manpower with the larger, older HMOs employing more of those personnel.     

How the elderly fare in HMOs: outcomes from the Medicare competition demonstrations.

Because of concern about the effects of prepaid care on outcomes for elderly enrollees in health maintenance organizations (HMOs), a prospective study of access to care and functional outcomes was performed. HMOs with Medicare risk contracts in January 1985 (N = 17) were selected from ten communities and were matched for comparison with ten similar communities where no Medicare HMOs were in operation. Random samples of HMO enrollees (N = 2,098) and fee-for-service (FFS) nonenrollees (N = 1,059) were assessed at baseline and at follow-up one year later (HMO = 1,873, FFS = 916) to observe access to care and functional outcomes. At baseline, nonenrollees had more bed days and poorer functional status than HMO enrollees. While fewer HMO enrollees experienced declines in functional status between baseline and follow-up (e.g., patient's ability to function declined in one or more activities of daily living: HMOs at 5.3 percent versus FFS at 8.5 percent, p < .01), after controlling for other factors with logistic regression, enrollment status was not significantly associated with functional decline. Self-rated health, history of hospitalization, age of 80 or older and baseline functional status were predictive of decline in function. After controlling for baseline differences, HMO disenrollees also experienced similar functional declines at follow-up compared to continuously enrolled beneficiaries. These findings suggest that Medicare beneficiaries who belong to HMOs experience comparable rates of functional decline to those experienced by beneficiaries in the FFS sector with similar initial levels of function and health status. Together with results showing no significant difference in medical visits according to various symptoms, we conclude that access and quality of care delivered by HMOs is comparable to that provided in FFS settings.     

Physicians contracting with managed care

It has been observed that enrollees in managed care systems such as HMOs and PPOs have lower expenditures and utilization rates than those in conventional insurance plans. Few studies have investigated this issue by examining providers. This paper studies whether physicians with low costs are more likely to sign contracts with HMOs and PPOs in order to help explain the observation of lower expenditures and utilization rates by HMO and PPO enrollees. A logistic regression is applied to the data from the 1984-1985 Physician Practice Costs and Income Survey. The results do not show strong evidence that a physician's likelihood of contracting with HMOs and PPOs is related to the physician's practice costs and utilization pattern. Instead, major factors that significantly affect a physician's decision of contracting with managed care systems are the physician's socio-demographics, the physician's practice region, and the market conditions.

Nutrition Academic Award: nutrition education in graduate medical education

The Nutrition Academic Award received by Tufts University School of Medicine strengthened our first-year Nutrition and Medicine course and clearly resulted in more nutrition in third-year clerkships and residency programs. Standardized patient cases in nutrition counseling for cardiovascular disease and weight loss were developed and incorporated into the clerkships and residency programs in internal medicine and family medicine. This was a value-added benefit that provided practice in initiating lifestyle changes and motivational skills, while expanding nutrition education. Eight standardized patient educators were trained in collaboration with physicians in internal and family medicine. Six slide shows on nutrition topics, 1-2 h each, were developed and included clinical cases, dietary analysis, and patient handouts. The Medicine Clerkship included 4 nutrition sessions and the standardized patient experience, whereas the Family Medicine Clerkship included 1 nutrition session and the standardized patient experience. Working with faculty in the Department of Family Medicine, we developed a nutrition mentoring program for the family medicine residents and used 3 nutrition messages that were a modification of the Dietary Approaches to Stop Hypertension (DASH) diet to teach diet evaluation, intervention strategies, feedback from nutrition referrals, and follow-up. Seven sessions on nutrition and chronic disease with cases were offered to the residents in family medicine, which concluded with a nutrition intervention session using standardized patient educators. This expanded nutrition program in internal and family medicine along with the standardized patient experience receives excellent ratings from physicians, residents, and medical students.     

Effect of managed care and financing on practice constraints and career satisfaction in primary care

BACKGROUND: The shift away from third party insurers to risk-sharing arrangements affecting care management and clinicians could be the most fundamental change in the health care system. Analysis was undertaken to study how managed care, practice setting, and financial arrangements affect physicians' perceived impact on their practice. METHODS: Data were taken from the Community Tracking Study (CTS) physician survey, a national survey of active physicians in the United States fielded between August 1996 and August 1997. Survey instruments were completed by 7,146 primary care physicians in internal medicine (2,355), family practice (3,168), and pediatrics (1,623). The dependent variables are career satisfaction and perceived limitations and pressures on time spent with patients, clinical freedom, income, and continuity. To study the unique effect of financing and gatekeeping arrangements and practice setting, the dependent variables were regressed on gatekeeping, practice revenue, individual physician compensation, practice setting, specialty, age-group, sex, international medical graduate, board certification, and recent change in practice ownership. RESULTS: Total managed care revenue, or individual physician incentives, have no effect on career satisfaction and relatively limited effects on time pressure, income pressure, or patient continuity. In contrast, primary care gatekeeping has a highly significant adverse effect on the same outcome measures. After controlling for financial factors, demographic characteristics, and training differences, physicians in solo and 2-physician practices are significantly more likely to be dissatisfied with their medical career, more likely to report no clinical freedom, and more likely to feel income pressure than physicians in group practices, staff model HMOs, medical schools, or other settings. CONCLUSION: Physicians in solo and 2-physician practices were least satisfied with their careers and reported more constraints on their clinical freedom and income than physicians in other settings. Physicians in group practices or staff model HMOs are more likely to report time pressure than physicians in solo or 2-physician practices. Family practice falls between internal medicine (less satisfied, more practice constraints) and pediatrics (more satisfied, fewer practice constraints).     

Medical Associates HMO

Medical Associates HMO is based on a multi specialty group practice located in a small metropolitan area. That group practice regards the HMO as an important strategy for maintaining and increasing patient referrals. A substantial portion of the HMOs service area is rural; therefore, the HMOs relationships with rural providers are important because they affect its ability to attract enrollees from rural areas and, potentially, non-HMO referrals as well. During the past few years, the competition for patients and for HMO enrollees has intensified in the HMOs market area. A major challenge facing this HMO is how to protect and enhance its market share while maintaining constructive, cordial relationships with providers in surrounding rural areas.
