Surplus or shortage? Unraveling the physician supply conundrum.

Although the supply of physicians in the United States has doubled during the past 20 years, there is still disagreement as to whether we currently have or should expect a significant surplus of physicians. The evidence suggests that despite the rapid expansion in the pool of available physicians, serious physician shortages persist for certain rural populations, ethnic and occupational groups, and other medically disadvantaged segments of the population. Medical students' declining interest in rural practice and primary care specialties suggests that problems of geographic and specialty maldistribution may worsen despite a rising population of physicians. It is unlikely that a significant physician surplus will develop unless there is a conscious attempt to limit the proportion of national wealth expended on medical care. Pockets of shortage can be reduced by broadening the availability of health insurance, lessening large income disparities between different specialties, changing the way teaching institutions are reimbursed for their training costs, and supporting direct governmental service programs such as the National Health Service Corps.

Time relations between the impulses of two motor units from symmetrical muscles upon voluntary control.

The activity of two motor units (MUs) belonging to two symmetrical muscles of both hands in six well trained subjects was investigated. Bipolar selective surface electrodes were used to lead off the electrical activity of mm interossei dig. dors. I or mm opponentes pollices. The "Medelec" electromyograph insured the visual and auditory feed-back from the firing MUs. The continuous or intermittent activity of both MUs was controlled voluntarily and simultaneously by the subjects. The probability of appearance of an impulse (the first or the last impulse in an intermittent train) from one unit when the other was firing continuously was studied. Alternation of the probability at 20 ms steps was found. At the same time the rhythm of the continuously firing MU was slightly affected. The data suggest a joint supraspinal influence or segmental contralateral outflow from the symmetrical motor pool. The hypothesis of the alphamotoneuron firing as a random process could not be used to explain the cases of joint activity.

The external costs of a sedentary life-style.

Using data from the National Health Interview Survey and the RAND Health Insurance Experiment, we estimated the external costs (costs borne by others) of a sedentary life-style. External costs stem from additional payments received by sedentary individuals from collectively financed programs such as health insurance, sick-leave coverage, disability insurance, and group life insurance. Those with sedentary life-styles incur higher medical costs, but their life expectancy at age 20 is 10 months less so they collect less public and private pensions. The pension costs come late in life, as do some of the medical costs, and so the estimate of the external cost is sensitive to the discount rate used. At a 5 percent rate of discount, the lifetime subsidy from others to those with a sedentary life style is $1,900. Our estimate of the subsidy is also sensitive to the assumed effect of exercise on mortality. The subsidy is a rationale for public support of recreational facilities such as parks and swimming pools and employer support of programs to increase exercise.

Serum micronutrients and risk of cancers of low incidence in Finland.

The associations between serum alpha-tocopherol, beta-carotene, retinol, retinol-binding protein, and selenium levels and the subsequent occurrence of different cancers of low incidence were investigated in a nested case-control study of 39,268 men and women participating in the Social Insurance Institution's Mobile Clinic Health Examination Survey in Finland. During follow-up from the baseline in 1968-1972 to the end of 1977, a total of 115 cancers of the lip, oral cavity, pharynx, larynx, esophagus, liver, gallbladder, kidney, urinary bladder, brain, and skin were reported to the nationwide Finnish Cancer Registry. Alpha-tocopherol, beta-carotene, retinol, retinol-binding protein, and selenium concentrations were determined from stored serum samples collected from these cancer cases and matched controls at baseline. Several sites indicated an elevated risk of cancer at low levels of the serum variables, although only a few of these associations were statistically significant. Only melanoma patients had significantly lower serum alpha-tocopherol and beta-carotene levels than corresponding controls. Since the numbers of cancer cases were small, no firm conclusions can be drawn from these results until they have been confirmed in studies based on larger cohorts or on pooled data from several small samples.

Health care for the indigent: overview of critical issues.

Health care for the indigent is a major problem in the United States. This review of the literature on health care for the indigent was undertaken to determine which major questions remain unresolved. Overall, this article finds that a very large pool of individuals under age 65 are at risk of being medically indigent. A myriad of health programs for some economically disadvantaged individuals do exist, but their level of funding has fluctuated over time--and many poor individuals must rely entirely on the generosity of a relatively small number of hospitals and other providers for their care. Economic pressures on these providers as well as structural changes in the health care sector can only adversely affect the amount of charity care that they offer. It is clear that a well-planned solution to indigent care in the United States, rather than a piecemeal approach, is needed.

An aggregate accident model based on pooled, regional time-series data.

The determinants of personal injury road accidents and their severity are studied by means of generalized Poisson regression models estimated on the basis of combined cross-section/time-series data. Monthly data have been assembled for 18 Norwegian counties (every county but one), covering the period from January 1974 until December 1986. A rather wide range of potential explanatory factors are taken into account, including road use (exposure), weather, daylight, traffic density, road investment and maintenance expenditure, accident reporting routines, vehicle inspection, law enforcement, seat belt usage, proportion of inexperienced drivers, and alcohol sales. Separate probability models are estimated for the number of personal injury accidents, fatal accidents, injury victims, death victims, car occupants injured, and bicyclists and pedestrians injured. The fraction of personal injury accidents that are fatal is interpreted as an average severity measure and studied by means of a binomial logit model.

Barriers to the care of persons with dual diagnoses: organizational and financing issues.

Among the frustrations of managing the dual disorders of chronic mental illness and alcohol and drug abuse is the fact that knowing what to do (by way of special programming) is insufficient to address the problem. The system problems are at least as intractable as the chronic illnesses themselves. Organizing and financing care of patients with comorbities is complicated. At issue are the ways in which we administer mental health and alcohol and drug treatment as well as finance that care. Separate administrative divisions and funding pools, while appropriate for political expediency, visibility, and administrative efficiency, have compounded the problems inherent in serving persons with multiple disabilities. Arbitrary service divisions and categorical boundaries at the State level prevent local governments and programs from organizing joint projects or creatively managing patients across service boundaries. When patients cannot adapt to the way services are organized, we risk reinforcing their overutilization of inpatient and emergency services, which are ineffective mechanisms for delivering the care these patients need. This article reviews the barriers in organization and financing of care (categoric and third party financing, including the special problem of diagnosis-related groups limitations) and proposes strategies to enhance the delivery of appropriate treatment.

A health investment that may save your life.

Breast cancer need not continue to be the devastating, deadly disease it has been in the past. With early detection, there is a higher rate of cure. There are three components to good breast health. These include (a) annual physical exam by a physician, (b) mammography according to the prescribed guidelines, and (c) monthly breast self-examination (BSE). When a woman does all three of these things, she's doing everything she can to insure early detection of breast cancer. This article discusses location, description, and characteristics of tumors. It also includes a teaching protocol developed for Midwest Breast Care Center in St. Louis, Missouri by the writer that includes risk factors, signs, and symptoms of breast cancer. It also includes new, comprehensive examination techniques set forth by the University of Texas System Cancer Center M. D. Anderson Cancer Center. The protocol is set up in a step-by-step format for easier teaching and learning. New, more thorough examination techniques have also been established at M. D. Anderson for the woman who has had a mastectomy and needs to examine the surgical site each month as well as her remaining breast. The article encourages women to take responsibility for their breast health and wellness.

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.

Point-of-service computer system and drug-use evaluation: implications for pharmacy practice in ambulatory care.

The point-of-service (POS) computer system and its possible effects on ambulatory-care pharmacy practice are described. The POS system, a key component of the Medicare Catastrophic Coverage Act, is an electronic claims-transmittal device to be installed in community pharmacies. The system transmits information about the patient and the prescribed drug to a claims processor, which verifies the eligibility of the patient for Medicare drug benefits, determines the amount of payment allowed, and sends information back to the POS terminal in less than 30 seconds. Because prescription information can be consolidated into a central data pool, drug-use patterns can be reviewed. The system will also permit automated screening of drug-drug interactions. Problems posed by the POS system relate to (1) the lack of a claims-transmittal device that can communicate with all claims processors, (2) the lack of a direct interface between the POS system and all pharmacy computer systems, (3) the expense of training personnel to operate the POS system, (4) the cost incurred by pharmacies in installing the POS system, and (5) the conflict between protecting the privacy of a patient's drug profile and permitting the monitoring of drug interactions. The catastrophic coverage act proposes that POS data be used to assess the appropriateness of drug use with a focus on outcome and quality-of-care issues; for the full intent of the act to be achieved, the components of an effective drug-use-evaluation program must be employed. Drug-use evaluation should eventually decrease health-care costs and improve quality of care.(ABSTRACT TRUNCATED AT 250 WORDS)

Group practice--trend for the future.

Group practices in various forms and combinations appear to set the trend for small animal practice management. By pooling their financial resources, energies, and talents, veterinarians can share the burden of increasing overhead costs and enjoy the benefits of specialization, new technologies, continuing education, consultations and referrals, peer review, applied research and publication, and fringe benefits such as paid vacation and sick leave, profit sharing, and pension. Group practices preserve ownership continuity at fair market value and afford opportunities for the utilization of expert business consultants. There are prerequisites to establishing a successful group practice: An adequate personal income base, a sufficient pet population, and business associates with compatible practice philosophy. Special considerations must be given to the social, economic, and psychological forces at work in a group practice environment. Professional and personal interactions can make or break a group practice. The group concept, MIP treatment of clients and their pets, and personalized appointments are important features which must be emphasized. The law of supply and demand and the law of diminishing returns must be kept in focus at all times. In tandem, they dictate the fortunes of all business enterprises and group practices can be particularly vulnerable to them. Long-term business commitment is a condition of group practice ownership and may pose a conflict with other interests. A predetermined buy-sell agreement and deferred compensation plan may provide the answer in case of dissolution, termination, or early retirement. A system of animal and material transport and transfer of business transactions and medical records must be set up between satellite clinics and the base hospital. A hospital-owned-and-operated shuttle service appears to offer the greatest flexibility and convenience. Cost-effectiveness of a shuttle service depends on the volume of referral cases generated for the base hospital. Computers may provide the answer to rapid and reliable transfer of data between satellite clinics and central or base hospitals in the near future. New approaches to small animal medicine and practice management must be explored and adopted. Prepaid pet medical insurance seems to be the answer to rapidly growing sophistication and escalating cost of small animal patient care. Human and companion animal interactions have been given a fresh impetus by veterinary educators, clinical psychologists, psychiatrists, humane societies, organizations for the mentally and physically handicapped, gerontologic centers, and others.(ABSTRACT TRUNCATED AT 400 WORDS)
