Has Medicare been a 'bad deal' for rural hospitals?

Understanding the links between Medicare involvement and financial performance in rural hospitals is important for evaluating reimbursement policy under Medicare's prospective payment system (PPS). While simple comparisons between urban and rural hospitals suggest that the latter have lower PPS profit margins on average, there is little multivariate evidence on how Medicare involvement affects financial performance in rural hospitals and whether this relationship differs between rural and urban hospitals. Existing multivariate evidence suggests that Medicare involvement improves PPS profits in both rural and urban hospitals after controlling for other hospital- and market-specific factors. By contrast, the present analysis considers the relationship between Medicare involvement and broader measures of profitability than PPS profits. This provides insight into whether Medicare reimbursement is adequate relative to other forms of third-party payment. The results indicate that Medicare involvement has a markedly different effect on the profitability of rural versus urban hospitals. Greater Medicare involvement is associated with lower patient care profitability in rural hospitals but has a strong positive and significant effect on both patient care and overall (i.e., patient and nonpatient) profitability in urban ones. Medicare involvement is not significantly related to overall profitability in rural hospitals, however, suggesting that these hospitals may be able to mitigate patient care revenue shortfalls from greater Medicare involvement by increasing their nonpatient care revenue sources.

Who cares for uninsured persons? A study of physicians and their patients who lack health insurance.

Physician involvement with uninsured patients is a topic of increasing policy interest. In the past, data limitations have hindered analysis of factors influencing physician contact with uninsured patients. This article attempts to bridge this gap in the health services research literature. Using a nationally representative sample of nonfederal patient care physicians, the study revealed marked variations in physician involvement with uninsured patients by specialty class, employment status, and other practice characteristics. Pediatricians and general practitioners had roughly comparable involvement with uninsured patients, while internists and surgeons were significantly less involved. Self-employed physicians generally participated less in caring for uninsured patients than did employed physicians. While definitive evidence that people without coverage face serious access problems is not provided, such a conclusion is certainly consistent with the results of this study. Indeed, the proportion of the average physician's patients who are uninsured is substantially below current estimates of the proportion of the general population that is uninsured.

Physician contact with and attitudes toward HIV-seropositive patients. Results from a national survey.

The growing population of HIV-seropositives raises serious concerns about who will provide medical care to this group. This article presents the first national estimates of physician involvement in, and attitudes toward, the treatment of HIV-seropositive patients. Nearly 50% of the nonfederal patient care physicians in our nationally representative sample have treated at least one HIV patient, with an average of 6.7 such patients being treated per physician. Perceived responsibility to treat HIV-seropositive patients is uniformly strong across such physician and practice characteristics as specialty, years of experience, and practice type. However, there are pronounced differences in actual physician involvement along these dimensions.

Physician advertising revisited.

This article examines the determinants of physician advertising using a nationally representative sample of 2,573 self-employed physicians. In contrast to a previous study by Folland, this article identifies a number of physician characteristics that are strongly related to the advertising decision. In particular, female physicians and foreign medical graduates (FMGs) are significantly less likely to advertise than are males and non-FMGs, respectively. Board certified physicians are less likely to advertise than are uncertified physicians. Also in contrast to previous results, primary care physicians are not necessarily more likely to advertise than nonprimary care physicians. For example, advertising propensity is strongest among plastic surgeons, whereas the propensity to advertise in such primary care specialties as internal medicine and pediatrics are quite close to advertising propensities for general surgeons. Furthermore, the relationship between practice size and advertising propensity is shown to be much stronger than previous research in this area has indicated. Finally, the results suggest that a number of physician characteristics associated with advertising through written media (newspapers or magazines) are also associated with advertising through audiovisual media (television or radio).

Labour productivity effects of prescribed medicines for chronically ill workers.

Previous work on the labour productivity effects of chronic illness has not separated the effects of chronic illnesses from the effects of prescription medications taken to alleviate these conditions. Using nationally representative observational data, this study estimates the pure effect of chronic illness, and the marginal effect of prescription medicines, on labour productivity. As Americans continue to scrutinize health care expenditures, such estimates will play an increasing role in determining the allocation of resources for medical treatments. Estimates are presented of the costs and benefits to employers of covering prescription medications for workers aged 18-64 years afflicted with specific chronic illnesses. The effects of prescription medicines on hourly wages and days lost from work are examined for four major chronic illnesses: hypertension, heart disease, non-insulin dependent (type II) diabetes and depression. The net benefits to employers from having workers take prescription medicines for their chronic illnesses are substantial. Assuming average compliance rates are achieved, net benefits to employers in 1987 amounted to $286 per hypertensive employee, $633 per employee with heart disease; $822 per depressed employee, and $1475 per type II diabetic employee under medication from a physician. These estimated benefits accrue because prescription medications substantially lower absenteeism among chronically ill workers.

Treatment of bancroftian filariasis in Recife, Brazil: a two-year comparative study of the efficacy of single treatments with ivermectin or diethylcarbamazine.

The effectiveness of single oral doses of ivermectin (200 or 400 micrograms/kg) and diethylcarbamazine (DEC, 6 mg/kg), preceded 4 d earlier by either placebo or very small doses of these drugs, was compared, over a 2-year period, in a double-blind trial in 67 microfilaraemic Brazilian men with bancroftian filariasis. Regimens containing ivermectin alone decreased the number of microfilariae significantly faster and more effectively for the first month after treatment than regimens containing DEC alone, but the latter were significantly more effective throughout the second year after treatment (1.7-8.2% of pretreatment levels with DEC vs. 12.6-30.8% with ivermectin during that period); the higher ivermectin dose showed a tendency towards more effectiveness than the lower dose. Most effective was the combination of ivermectin (20 micrograms/kg) followed 4 d later by DEC (6 mg/kg), with reduction of microfilaraemia to 2.4% of pretreatment levels at 2 years. Adverse reactions were well tolerated with all regimens, the reactions being significantly more generalized (i.e., fever) following ivermectin and localized (i.e., scrotal inflammatory nodules around dying adult worms) following DEC. Further trials of single-dose combination therapy vs. single high doses of ivermectin or DEC should determine the ideal regimen for treatment and control of bancroftian filariasis.

The costs and effects of switching calcium channel blockers: evidence from Medicaid claims data.

This study used Medicaid claims data from Pennsylvania to examine the costs and effects of changing calcium channel blocker therapies. Specifically, we compared Procardia XL with Adalat CC. They are the only once-daily-dosed, extended-release forms of nifedipine available. These drugs were interesting to compare for several reasons. First, because the frequency of treatment regimens has been shown to be the most important determinant of long-term compliance with calcium channel blocker medications, it was desirable to compare drugs having identical dosing regimens. Second, switching from one to the other should be quite feasible in most patients. Third, Adalat CC is priced (ie, average wholesale price) less than Procardia XL. The results indicate that prescription prices were lower when patients were switched from Procardia XL to Adalat CC, with no apparent effects on blood pressure control, the incidence of adverse drug reactions, or nonprescription health care costs. The potential savings to Medicaid from switching patients from Procardia XL to Adalat CC appears to be large, more than $2.5 million annually for Procardia XL-treated Medicaid patients in the state of Pennsylvania. Our study also demonstrates that large retrospective databases can be used to evaluate economic and clinical outcomes for specific therapy alternatives. Such evaluations are increasingly relevant to third-party payers, health maintenance organizations, and other parties involved in managed care.

Variations in compliance among hypertensive patients by drug class: implications for health care costs.

Health care decision-makers require more information on differences in compliance rates associated with alternative classes of antihypertensive drugs and the implications of these differences for health care utilization and costs. We examined medical claims data from the Pennsylvania Medicaid Management Information System to investigate compliance rates for four major antihypertensive drug classes (angiotensin-converting enzyme [ACE] inhibitors, beta-blockers, calcium antagonists, and diuretics) and the health care costs associated with noncompliance. Multivariate analysis was used to relate antihypertensive drug class with compliance and variations in compliance with health care costs. The highest estimated rates of compliance were associated with ACE inhibitors and calcium antagonists, and these rates were significantly greater than with beta-blockers and diuretics. Moreover, poor compliance was associated with higher health care costs. Efforts to increase compliance with antihypertensive drug therapy are needed to improve patient outcomes and reduce health care costs.

[Beclomethasone dipropionate, in high dose, in the treatment of patients with chronic persistent asthma].

The efficacy of inhaled beclomethasone dipropionate (BDP) was examined in 8 patients with chronic persistent asthma, uncontrolled by inhaled bronchodilators and oral theophylline. Beclomethasone was administered at a dose of 1500 mcg a day, using a metered dose inhaler containing 250 mcg of BDP per dose. The medication was administered twice daily, three 250 mcg puffs at 8 A.M. and three at 8 P.M. The patients were assessed by means of clinical examination, diary records and daily Peak Flow Rate (PFR) measurement made at home. The therapeutic responses were measured over an 8-wk period. The clinical score (0-4) improved significantly (3.25 +/- 0.71 before and 0.75 +/- 0.89 after [p < 0.001]), and the peak flow rate rose from baseline mean value of 48.0% +/- 11.9 (predicted value) to 78.8% +/- 16.7% with significant improvement (p < 0.01). Of the total of 8 patients, 5 achieved complete control of symptoms and normal values of PFR, 1 remained with sporadic wheezing but with significant improvement of PFR and 2, despite the clinical efficacy in symptom relief, persisted without significant improvement on PFR values. Transitory hoarseness occurred in 1 patient. No other side-effects were observed.

The cost of medical professional liability.

The high cost of medical professional liability is a source of growing concern among policymakers, health care consumers, and the medical profession. While the concern is widespread, to date there has been little quantitative evidence on the overall economic impact of the problem. Utilizing data from the American Medical Association's Socioeconomic Monitoring System, the impact of medical professional liability (PL) on the cost of physicians' services has been estimated employing two different methods. Both estimates indicate that the costs of PL are substantial. In particular, the two methods yield estimates of the total cost of PL in 1984 of $13.7 and $12.1 billion, respectively--or approximately 15% of the total expenditures on physicians' services. Furthermore, increased costs associated with PL from 1983 to 1984 alone are estimated under the two methods to have accounted for 63% and 57%, respectively, of the increase in expenditures on physicians' services. These costs include PL insurance premiums, costs of practice changes made in response to increasing PL risk, and costs of incurring claims that are not covered by PL insurance.

Physician income targets: new evidence on an old controversy.

This study uses a unique set of data to identify the factors that affect physician income targets among a nationally representative sample of young (under age 40) physicians in 1987. The study reveals that income targets respond directly to actual income, but that this relationship is rather inelastic. Among self-employed physicians, for example, a 10% decline in actual income would reduce the target by only 3%. Thus, our study provides the first direct evidence to quantify how a decline in income will increase the divergence between actual and target income. Moreover, in quantifying this divergence, our results provide an upper bound on the dollar value of any demand inducement that may ensue. The results suggest that targets are set, at least in part, to compensate physicians for pecuniary and nonpecuniary costs associated with medical practice. Discrimination, dissatisfaction, financial risks, and training costs all appear to raise income targets. Physicians may desire higher incomes to compensate them for discrimination or other difficulties they have encountered in practicing medicine.
