Health-related quality of life effects of modafinil for treatment of narcolepsy.

OBJECTIVE: To evaluate the burden of illness of narcolepsy and assess the health-related quality-of-life (HQL) effects of oral modafinil, a wake-promoting therapy for excessive daytime sleepiness associated with narcolepsy. METHODS: Subjects with narcolepsy enrolled in a nine-week, placebo-controlled, double-blind study and were randomized to placebo, modafinil 200 mg, or modafinil 400 mg. After the study, consenting subjects received modafinil in a 40-week open-label extension. A self-administered HQL questionnaire consisting of the 36-Item Short Form Health Survey (SF-36) and supplemental narcolepsy-specific scales was given to subjects at baseline, study endpoint, and several open-label timepoints. RESULTS: 481 subjects completed a baseline and double-blind endpoint HQL assessment. Compared to population norms, baseline HQL scores reflected substantial burden in vitality, social functioning, and performing usual activities. At study endpoint, subjects in the 400 mg modafinil group had significantly higher scores than placebo for 10 of the 17 HQL scales. The 400 mg modafinil group had more energy, fewer difficulties performing usual activities, fewer interferences with social activities, improved psychological well-being and higher productivity, attention and self-esteem compared to placebo subjects (p<.05). The positive treatment effects were sustained over the open-label extension. CONCLUSION: Modafinil significantly improves health-related quality of life in narcolepsy.

Assessment of the frequency and costs of posttransplantation hospitalizations in patients receiving tacrolimus versus cyclosporine.

We assessed the frequency and costs of hospitalizations in patients receiving tacrolimus (FK506) compared with patients receiving cyclosporine A for immunosuppression during 1 year after kidney transplantation. Four hundred twelve cadaveric kidney transplant recipients were randomized onto a phase III, prospective, multicenter, clinical trial. Hospital billing data were collected for 1 year posttransplantation. Total inpatient costs were calculated from billed charges and standardized to 1995 US dollars. Medical resource utilization rates and inpatient costs were compared between treatment groups using unpaired Student's t-tests. Complete billing data (transplantation and all posttransplantation hospitalizations) were available for 65% (268 of 412) of the study patients. Among tacrolimus and cyclosporine patients with complete billing data, the rates of allograft rejection were 32% and 47%, respectively (P=0.009), and the rates of rehospitalization during the year after transplantation were 53% and 63%, respectively (P=0.080). The mean per-episode rehospitalization costs were significantly lower among tacrolimus-treated patients compared with cyclosporine-treated patients ($7,495 v $11,497; P=0.031), and the mean total rehospitalization costs were significantly lower in the tacrolimus group compared with the cyclosporine group ($8,550 v $14,869; P=0.029). In addition, the total 1-year hospitalization costs (including transplantation and posttransplantation hospitalizations) were significantly lower in the tacrolimus group compared with the cyclosporine group ($53,435 v $61,191; P=0.046). Compared with cyclosporine-based immunosuppression, tacrolimus-based immunosuppression for kidney transplant recipients was associated with a significantly lower rate of rejection, which was associated with significantly lower per-episode rehospitalization costs, lower total 1-year rehospitalization costs, and lower total 1-year hospitalization costs.

Usefulness of the SF-36 Health Survey in measuring health outcomes in the depressed elderly.

Longitudinal data from a clinical trial were analyzed to evaluate the usefulness of the SF-36 Health Survey in estimating the impact of depression and changes in severity over time on the functional health and well-being of 532 patients, 60 to 86 years of age, who met DSM-III-R criteria for major depressive disorder. The Hamilton Depression Rating Scale, the Clinician's Global Impression of Severity and Improvement, and the Geriatric Depression Scale were used to define clinical severity and changes in severity over a 6-week period. Answers to SF-36 questions tended to be complete and to satisfy assumptions underlying methods of scale construction and scoring. As hypothesized, the SF-36 Mental Health Scale and Mental Component Summary measure, shown in previous studies to be most valid in measuring differences in mental health, exhibited the strongest associations with severity of depression in cross-sectional analyses and were most responsive to changes in severity in longitudinal comparisons. We conclude that the SF-36 Health Survey is useful for estimating the burden of depression and in monitoring changes in functional health and well-being over time among the depressed elderly.

The effects of recombinant human erythropoietin on functional health and well-being in chronic dialysis patients.

As a component of the open-label, multicenter National Cooperative Recombinant Human Erythropoietin (Epo) Study, the health-related quality-of-life effects of Epo therapy were assessed in 484 dialysis patients who had not previously been treated with Epo therapy (New-to-Epo) and 520 dialysis patients who were already receiving Epo therapy at the time of study enrollment (Old-to-Epo). Using scales from the Medical Outcomes Study 36-item Short Form Health Survey (SF-36), health-related quality of life was assessed on study enrollment (baseline) and at an average of 99 days follow-up. At baseline, SF-36 scores for Old- and New-to-Epo patients were well below those observed in the general population, reflecting substantial impairments in functional status and well-being among patients with chronic renal failure. Significant improvements from baseline to follow-up were observed among New-to-Epo patients in vitality, physical functioning, social functioning, mental health, looking after the home, social life, hobbies, and satisfaction with sexual activity (P < 0.05 for each). The mean improvements in hematocrit values among New-to-Epo and Old-to Epo patients were 4.6 and 0.3, respectively. At the time of follow-up, SF-36 scores for New-to-Epo patients were comparable with those observed among Old-to-Epo patients, whose scores did not change significantly from baseline to follow-up. Analysis of the relationship between Epo therapy, hematocrit values, and health-related quality of life suggest that some of the beneficial quality-of-life effects of Epo are mediated through a change in hematocrit level.

Health plan selection in the Federal Employees Health Benefits Program.

A survey of over 8,500 employees of the U.S. Department of Health and Human Services (DHHS) during the May 1982 open season, supplemented by enrollment data for all DHHS employees enrolled in the Federal Employees Health Benefits Program (FEHBP), was used to study insurance plan selection when multiple fee-for-service options as well as HMOs are available. There is evidence of biased selection of health risks in the FEHBP, yet historically the program has exhibited considerable stability. The stability may be attributable partly to control over entry and over changes in benefits and premiums and partly to inertia on the part of enrollees. In spite of large changes in relative premiums and benefits, only 21 percent of all enrollees in the DHHS switched plans during the May 1982 open season. Those employees who did switch plans astutely identified bargains; on average they lowered their annual contribution to premium by almost 40 percent while maintaining the level of benefits. Insurance plans offering relatively generous coverage of a particular service attract a disproportionately high share of enrollees who expect substantial use of that service. The extent of adverse or beneficial selection into HMOs depends on the price and the comprehensiveness of benefits of each available fee-for-service option.

Compensation of hospital-based physicians.

This study is concerned with methods of compensating hospital-based physicians (HBPs) in five medical specialties: anesthesiology, pathology, radiology, cardiology, and emergency medicine. Data on 2232 nonfederal, short-term general hospitals came from a mail questionnaire survey conducted in Fall 1979. The data indicate that numerous compensation methods exist but these methods, without much loss of precision, can be reduced to salary, percentage of department revenue, and fee-for-service. When HBPs are compensated by salary or percentage methods, most patient billing is conducted by the hospital. In contrast, most fee-for-service HBPs bill their patients directly. Determinants of HBP compensation methods are investigated via multinomial logit analysis. This analysis indicates that choice of HBP compensation methods are investigated via multinomial logit analysis. This analysis indicates that choice of HBP compensation methods is sensitive to a number of hospital characteristics and attributes of both the hospital and physicians' services markets. The empirical findings are discussed in light of past conceptual and empirical research on physician compensation, and current policy issues in the health services sector.

Union activity in hospitals: past, present, and future.

Between 1970 and 1980, the percentage of hospitals with one or more collective bargaining contracts increased from 15.7 percent to 27.4 percent. A substantial amount of variation exists in the extent of unionism on the basis of hospital ownership, bed size, and location. Employees are more likely to organize when hospitals in the State are regulated by a mandatory rate-setting program. Unions raise hospital employee's wages--a modal estimate for RNs is about 6 percent; the corresponding figure for nonprofessional employees is about 10 percent. Growth of union activity in hospitals has generally not been a major contributor to hospital wage inflation, and less than 10 percent of the increase in real (relative to the Consumer Price Index) spending for hospital care that occurred during the 1970s can be attributed to union growth. We project that between 45 and 50 percent of all hospitals will have at least one union by 1990.

Hospital-based physicians: current issues and descriptive evidence.

Hospital-based physicians (HBPs) have been the recipients of considerable attention in health policy debates in recent years. This paper discusses issues and trends concerning HBPs and presents evidence on practice characteristics, compensation methods, and incomes of anesthesiologists, pathologists, and radiologists. Some comparisons with office-based MDs are included. The primary data source is composed of physician surveys sponsored by the Health Care Financing Administration and conducted by the National Opinion Research Center in 1977 and 1978. Findings generated from these surveys support past research showing that radiology is the most lucrative HBP specialty, followed by pathology and anesthesiology; hospital-based practice tends to be considerably more lucrative than office-based practice, taken as a whole. Survey findings are discussed in light of current policy developments in the health services sector.

Physician participation in health insurance plans: evidence on Blue Shield.

Various health insurance programs, including Blue Shield, have developed arrangements whereby the physician agrees to accept the insurer's reimbursement as payment in full. Incentives facing the physician to accept an arrangement of this type are reviewed in this study. The empirical work uses data on individual physicians from a 1973 survey. The results indicate that physician willingness to accept insurer reimbursement as payment in full is sensitive to the amount the insurer pays for specific procedures and to other insurance program characteristics. Physicians located in high patient income areas and/or with relatively prestigious credentials are less likely to accept insurer payments as payment in full. The empirical findings are used to generate policy implications pertaining to the Medicare and Medicaid programs, to medical care quality-access tradeoffs, and to national health insurance.

The effect of preceptorship and rural training programs on physicians' practice location decisions.

This study analyzes the relationship between medical student participation in rural training programs, including preceptorships, and the decision to locate medical practice in rural areas. Data consist primarily of responses to questionnaires mailed in 1972 to all graduates of United States medical schools in 1965. Study findings indicate that the overall impact of such programs on practice location decisions is relatively slight, but is most pronounced with respect to urban-reared physicians in nonprimary care specialties. It was also found that a large proportion of urban-located physicians had seriously considered rural practice and that the reluctance of many physicians to locate in rural areas is linked to fear of professional isolation. The findings suggest that an increased orientation toward urban-reared students and dissemination of information on nonsolo practice opportunities in rural areas are means of increasing the effectiveness of preceptorships and other rural training programs in attracting young physicians to underserviced areas.
