Understanding the recent growth in Medicare physician expenditures

This study employs several large Health Care Financing Administration data sets for 1983 and 1985 to examine the recent growth in Medicare physician services. The study concludes that the recent growth (approximately 15% in real terms between 1983 and 1985) has been more rapid in areas with higher incomes per capita and suggests that this may be related to faster adoption and diffusion of new medical technologies in these areas. The volume of physician services had grown considerably faster for those specialists who utilize newer procedures and technologies than for those who do not. The study also provides evidence that the sharp increase in assignment rates in recent years because of the introduction of the physician participation program also contributed to the growth in physician services during this period. Medicare's prospective payment system, which controlled hospital payments and encouraged hospitals to become more efficient, had at most a small positive impact on the growth in Part B spending. Finally, the freeze on physician's fees did not seem to have had a major impact on the volume of physician services.     

Cost and case-mix differences between hospital-based and freestanding nursing homes.

Cost differences between freestanding and hospital-based skilled nursing facilities (SNF's) are identified and examined in this article. Although hospital-based and freestanding SNF's have significant differences in terms of location, admissions per bed, percent of Medicare days, occupancy rates, staffing, provisions of rehabilitative services, and patient characteristics, these are insufficient to fully explain cost differences. Less than one-half of the existing cost differences can be explained after controlling for case mix, staffing, and other cost-contributing factors. A reimbursement system that differentiates solely by provider type without relating rates to patient characteristics may overcompensate some providers and undercompensate others.     

Predictors of alcoholics' acquisition of treatment-related knowledge

Only modest relationships have been found between cognitive functioning and treatment outcome; there is some indication of better prediction of within-treatment progress. The current study attempted to determine whether either cognitive or sociodemographic/alcohol-related variables were predictive of learning in educational treatment. Eighty-seven male alcoholics were exposed to one hour of instruction on the medical effects of alcohol. Sociodemographic, alcohol-related, and cognitive functioning measures were obtained at the outset of treatment. Knowledge was assessed 24 hours prior to and 24 hours and three weeks after the intervention. Statistically significant increases in knowledge were found both 24 hours and three weeks following the educational intervention; retention of information declined significantly from 24 hours to three weeks post-intervention. Discriminant function analyses using either seven cognitive variables or six alcohol-related/sociodemographic variables significantly discriminated between learners and nonlearners 24 hours after the intervention. The weighted composite of measures in each of the analyses was able to successfully differentiate learners from nonlearners in over 70% of the cases. The findings suggest that the clinician may be able to employ a limited number of variables to differentiate between patients who will and will not be able to acquire knowledge from educational interventions.     

A leg ulcer as manifestation of metastatic squamous cell vaginal carcinoma

Cutaneous metastasis of vaginal carcinoma is extremely rare. So far, the total number of reported skin metastasis of vaginal carcinoma is only one. We present another case with an unusual manifestation of vagina carcinoma metastasis: skin metastasis presenting as a leg ulcer on the lower leg.
