Use of community-based mental health programs by HMOs: evidence from a Medicaid demonstration.

Background: Proposals to enroll Medicaid beneficiaries in health maintenance organizations (HMOs) have raised concerns that community-based mental health treatment programs would be adversely affected.

Methods: In Hennepin County (Minnesota) 35% of Medicaid beneficiaries were randomly assigned to prepaid plans. Random samples of individuals with severe mental illness with selected from the prepaid enrollees and from beneficiaries remaining with traditional Medicaid.

Accuracy of diagnoses of schizophrenia in Medicaid claims.

Medical insurance claims are increasingly important as a source of data in monitoring health care utilization and patient outcomes and in identifying patient cohorts for research. In a study that attempted to verify that those with Medicaid claims for treatment of schizophrenia did indeed have the disorder, two psychiatrists evaluated clinical information obtained from primary mental health care providers in relation to DSM-III-R criteria. The psychiatrists classified 86.

A public hospital closes. Impact on patients' access to care and health status.

We studied the impact of the closing of a public hospital on patients' access to care and health status. We surveyed individuals who had been medical inpatients at Shasta General Hospital, Redding, Calif, in the year prior to its closing and compared them with those in a second county, San Luis Obispo, whose public hospital did not close. Surveys were administered after the closing of Shasta General Hospital and 1 year later.

Measuring health changes among severely ill patients. The floor phenomenon.

The interest in measuring health status with survey instruments has not been matched with an analysis of their performance characteristics in the field. We used the Medical Outcome Study Short Form (MOS-20) to assess health outcomes among patients who were hospitalized in one of two public hospitals. We mailed the MOS-20 and a series of transition questions, which asked about changes in health, to patients admitted in the previous year.

A controlled trial of intravenous immunoglobulin G in chronic fatigue syndrome.

Purpose: Currently, there is no established therapy for chronic fatigue syndrome (CFS), a recently defined illness that has been associated with a variety of immunologic abnormalities. Based on the hypothesis that a chronic viral infection or an immunoregulatory defect is involved in the pathogenesis of CFS, the therapeutic benefit of intravenous immunoglobulin G (IV IgG) was evaluated in a group of patients with CFS. Additionally, serum immunoglobulin concentrations and peripheral blood lymphocyte subset numbers were measured at the outset of the study, and the effect of IV IgG therapy on IgG subclass levels was determined.

Attitudes of internal medicine faculty and residents toward professional interaction with pharmaceutical sales representatives.

We surveyed faculty and residents from seven hospitals affiliated with three academic internal medicine training programs about their perceptions of the informational and service benefits vs the risks of ethical compromise involved in interactions with pharmaceutical sales representatives. Questionnaires were returned by 467 (81%) of 575 physicians surveyed. Residents and faculty generally had somewhat negative attitudes toward the educational and informational value of detailing activities at their institutions but indicated that representatives supported important conferences and speakers.

Teaching status and resource use for patients with acute myocardial infarction: a new look at the indirect costs of graduate medical education.

To investigate whether the process of graduate medical education increases costs in teaching hospitals by causing longer lengths of stay and greater resource use, we compared lengths of stay, hospital charges, and the use of cardiovascular procedures for patients with acute myocardial infarction admitted to the teaching and nonteaching services of a university-affiliated community hospital. After adjusting for severity of illness and demographic characteristics, patients on the teaching services had a mean length of stay that was shorter by 0.6 days (p = 0.

Do-not-resuscitate orders in an extended-care study group.

We examined the charts of 911 nursing home patients in Hennepin County, Minnesota, to determine the prevalence of written do-not-resuscitate (DNR) orders. Information regarding demographic characteristics, and whether a surrogate decisionmaker was available and participated in the decision, was also collected. Twenty-seven percent of patients had DNR orders.

Pharmaceutical representatives in academic medical centers: interaction with faculty and housestaff.

Objective: To determine the nature, frequency and effects of internal medicine housestaff and faculty contacts with pharmaceutical representatives (PRs).

Design And Setting: The authors surveyed internal medicine faculty at seven midwest teaching hospitals and housestaff from two of the teaching programs. The survey asked about type and frequency of contacts with PRs and behavior that might be related to these contacts.

The Minnesota Clinical Comparison and Assessment Project.

Efforts to quantify and improve the effectiveness and efficiency of health care services are critical to the health care system in the United States. Essential components of these efforts are clinician involvement and support and reliable clinical information systems. Organized medicine and the hospital industry in Minnesota have initiated and funded the Minnesota Clinical Comparison and Assessment Project (MCCAP) to begin to document, compare, and improve health care services.

Assessment of medical outcomes. New opportunities for achieving a long sought-after objective.

Health outcome assessment may be used for a variety of purposes: to evaluate the effectiveness of medical practices; to assess the quality of services provided; to educate providers, purchasers, and users of health services about the sequelae of treated and untreated disease; to guide reimbursement and regulatory policy; and to characterize the health status of a population. This article focuses on the use of health outcomes to evaluate the effectiveness of medical practices and to assess the quality of services provided.

Teaching residents to care for vulnerable populations in the outpatient setting.

Residency programs have an obligation to teach house officers to care for vulnerable populations. Such populations consist of those whom physicians tend to consider undersirable as patients, and thus who often lack adequate care, because they cannot pay for medical services, because they have medical problems that are difficult to manage, or because they have characteristics giving them low social status. The authors identify and discuss key aspects of learning to care for such populations.

Health care cost containment measures and mortality in Hennepin County's Medicaid elderly and all elderly.

In Minnesota, several health care cost containment measures occurred about the time Medicare's Prospective Payment System (PPS) was implemented. These included a moratorium on additional nursing home beds, preadmission screening of nursing home applicants, and rapid growth in HMO (health maintenance organization) enrollment by Medicare recipients. Hospital days per elderly Medicaid recipient decreased by 38 percent for those in nursing homes and by 35 percent for those not in nursing homes from 1982 to 1984.

How do house officers spend their nights? A time study of internal medicine house staff on call.

Recommendations to limit the working hours of house staff are forcing directors of training programs to reevaluate how house officers spend their time. We studied how 35 house officers in internal medicine spent their on-call time in three teaching hospitals: an urban county hospital, a university hospital, and a regional Veterans Administration medical center. Trained observers accompanied each member of different on-call teams for five nights and quantified how their time was spent.

How free care improved vision in the health insurance experiment.

We studied reasons for the improvement in the functional vision of enrollees receiving free care in the Rand Health Insurance Experiment. Among low income enrollees, 78 per cent on the free plan and 59 per cent on the cost-sharing plans had an eye examination; the proportions of those obtaining lenses were 30 per cent and 20 per cent, respectively. Visual acuity outcomes of low income vs non-poor enrollees were more adversely affected by enrollment in cost-sharing plans.

Mainstreaming the mentally ill in HMOs.

Administratively complex and politically sensitive issues can arise when mentally ill persons who are public program beneficiaries are enrolled in existing HMOs. The experiences of a demonstration program undertaken in Minnesota illustrate these issues.

Differences in inpatient resource use by type of health plan.

Approximately 50% of the annual increase in hospital costs comes from increased resource use per hospital admission. Health maintenance organizations (HMOs), given their fixed financial resources for patient care, have an incentive to constrain their enrollees' use of hospital resources. Our analysis investigates differences in length of stay, total charges, and the ancillary to total charge ratio for hospitalized patients in network HMOs, independent practice associations (IPAs), and fee-for-service (FFS) health plans in the Twin Cities from 1982 to 1984.

Use of the hospital in a randomized trial of prepaid care.

Health maintenance organizations (HMOs) achieve their cost savings through lower rates of hospital admissions. To determine whether HMOs selectively avoid discretionary hospitalizations, medical records were reviewed from a randomized trial where families were assigned to either HMO or free-for-service care. Physicians who were blinded to system reviewed 244 medical records and judged the appropriateness both of the hospital setting and of the medical indications for hospitalization.
