Prepayment with office-based physicians in publicly funded programs: results from the Children's Medicaid Program.

This paper is a report of the results of a demonstration designed to provide empirical evidence regarding the effects of alternative approaches to paying physicians for serving children in the Medicaid program: (1) visit fees set at twice regular Medicaid fees in return for physician agreement to manage utilization and (2) capitation and financial risk-sharing along with the same physician agreement to manage utilization. Participating physicians were assigned randomly to either of the two payment groups. Comparisons of utilization and expenditures were made between these two plans and the regular Medicaid program (fee-for-service, low fees). Results showed no adverse effect of capitation payments on primary care visits to office-based physicians. Capitation physician referrals to specialists decreased relative to all other groups studied, consistent with the theory that the financial incentives in capitation will lead primary care physicians to reduce referrals to specialists.

[Results of a multiphase oncology population screening program in the community of Becej 1986-1987. I. The Hemoccult Program].

In the framework of a multiphase oncologic population screening-program performed in persons above 40 years of age according to the census in the community of Becej during 1986-1987, Hemoccult screening program, together with the fluorographic action involved 16.895 (83.80%) persons out of 20.160 predicted ones which was far less than the involvement of persons through the distribution and gathering of the screening material by a specialized nurse. In 907 (5.37%) Hemoccult positive persons out of which 121 (13.34%) persons rejected to cooperate or did not respond to the invitation for further investigation 16 malignant neoplasms in the lower part of the colon (anus 1, rectum 11, sigma 4) were detected as well as 53 polyposes of the rectum and the anus. Besides, 4 malignant neoplasms of the skin were found and 29 benign tumours (27 adenomas of the prostate gland, 1 fibrolipoma glutei and 1 cysta renis). Apart from these diseases 569 other previously not treated pathologic states were found, i.e. new pathologic states were detected in 85.37% of Hemoccult-positive persons. Previously known pathologic states were confirmed in 22.52% of Hemoccult-positive persons. Diagnostic was performed by the rigid rectoscope and in Hemoccult-positive persons with the negative rectoscopis finding radiologic and fiberoscopic investigations were carried out in the less scope due to the deficiency of financial resources. The number of detected malignant neoplasms of the colon surpassed the three-fold value of the average Vojvodina incidence of these localizations of malignant neoplasms at this age.(ABSTRACT TRUNCATED AT 250 WORDS)

An evaluation of a program to regulate rural hospital costs: the Finger Lakes Hospital Experimental Payment program.

In 1981 eight small- and medium-sized hospitals in a rural area of New York State began voluntary participation in the Finger Lakes Hospital Experimental Payment (FLHEP) program. An annual maximum reimbursement formula was set for each hospital, which offered financial incentives to contain the growth in expenditures without penalty in subsequent years. In this analysis of the first three years of the program, we found that the growth in revenues and expenses in study group hospitals was reduced and chronic deficits were eliminated. The FLHEP model may have wider potential for ensuring solvency while controlling expenditures of hospitals in other rural areas of the United States.

Persistence of reduction in blood pressure and mortality of participants in the Hypertension Detection and Follow-up Program. Hypertension Detection and Follow-up Program Cooperative Group.

The Hypertension Detection and Follow-up Program (HDFP) previously described a significant reduction in five-year, all-cause mortality in its intensively treated stepped care (SC) group relative to its referred care (RC) control group. At the time this finding was described, a proportion of the SC cohort had been treated for periods as long as 6.7 years, but comparable RC and SC mortality data beyond five years were not available. These data, which are described herein, indicate that the 6.7-year life-table mortality rates were 95.1/1000 participants for SC vs 116.3/1000 participants for RC, a larger mortality difference than was observed at five years. This favorable finding for SC extended to all major subgroups, including white women and those aged 30 to 49 years at trial entry. Six months after the close of the treatment trial, a two-year posttrial surveillance study, which extended mortality follow-up to 8.3 years, was conducted. The posttrial use of antihypertensive medication declined in SC and increased in RC participants so that by the end of the posttrial period, there was little difference in the percentages of SC and RC participants taking medication. Control of blood pressure, indicated by mean diastolic blood pressure and by percent of participants with a pressure of 90 mm Hg or less, was slightly better for SC than for RC participants (SC group, 86.5 mm Hg and 68% controlled; RC group, 87.8 mm Hg and 62% controlled). The absolute mortality advantage found at 6.7 years persisted and increased throughout the posttrial period of follow-up despite discontinuation of the formal SC therapy program. It is postulated that regression of hypertensive end-organ changes brought about by the more effective SC treatment caused this favorable outcome.

Educational level and 5-year all-cause mortality in the Hypertension Detection and Follow-up Program. Hypertension Detection and Follow-up Program Cooperative Group.

Excess mortality in persons of lower socioeconomic status is a finding confirmed in many population studies. Among the nearly 11,000 hypertensive trial participants in the population-based Hypertension Detection and Follow-up Program, lower educational level (an indicator of low socioeconomic status) was associated with a 5-year death rate significantly above that found in those with higher education. This report examines whether this excess was observed uniformly within both treatment groups--stepped care and referred care--or whether the more vigorous antihypertensive program of stepped care was able to reduce the mortality gradient associated with education. In addition, impact on mortality of degree of blood pressure control during the trial was assessed within stepped and referred care groups, taking account also of educational level. Finally, the benefit of stepped care compared with referred care (control group) in reducing mortality was analyzed, controlling for education. Referred care participants with less than a high school education had a 5-year death rate twice as high as those with more than a high school education, whereas no such gradient of mortality was seen in the stepped care group. Level of blood pressure control throughout the trial was better in the stepped than in the referred care group and was significantly (inversely) associated with mortality in the stepped care group, regardless of educational level. In the referred care group as well, the better the control of elevated blood pressure (again, regardless of educational level), the lower the mortality, although this inverse association did not quite reach statistical significance in the referred care group.(ABSTRACT TRUNCATED AT 250 WORDS)

A wellness program model for family practice residency programs.

For some time health promotion and disease prevention have been expected tenets of medical practices with the public. However, the medical profession has only recently emphasized prevention and wellness promotion as required curricula for study at the undergraduate and graduate levels. Family physicians have been at the forefront in accepting this additional responsibility, but actual implementation of such practices has been difficult for the individual physician. To address this needed transitional step from public demand to practice, a wellness program for residents, faculty, staff, and patients was designed for the Family Practice Residency Program at Cheyenne.

Five-year findings of the hypertension detection and follow-up program. I. Reduction in mortality of persons with high blood pressure, including mild hypertension. Hypertension Detection and Follow-up Program Cooperative Group.

The Hypertension Detection and Follow-up Program (HDFP), in a community-based, randomized controlled trial involving 10,940 persons with high blood pressure (BP), compared the effects on five-year mortality of a systematic antihypertensive treatment program (Stepped Care [SC]) and referral to community medical therapy (Referred Care [RC]). Participants, recruited by population-based screening of 158,906 people aged 30 to 69 years in 14 communities througout the United States, were randomly assigned to SC or RC groups within each center and by entry diastolic blood pressure (DBP) (90 to 104, 105 to 114, and 115 + mm Hg). Over the five years of the study, more than two thirds of the SC participants continued to receive medication, and more than 50% achieved BP levels within the normotensive range, at or below the HDFP goal for DBP. Controls of BP was consistently better for the SC than for the RC group. Five-year mortality from all causes was 17% lower for the SC group compared to the RC group (6.4 vs 7.7 per 100, P less than .01) and 20% lower for the SC subgroup with entry DBP of 90 to 104 mm Hg compared to the corresponding RC subgroup (5.9 vs 7.4 per 100, P less than .01). These findings of the HDFP indicate that the systematic effective management of hypertension has a great potential for reducing mortality for the large numbers of people with high BP in the population, including those with "mild" hypertension.

The role of parents and older peers in school-based cardiovascular prevention programs: implications for program development.

This article describes a set of studies which compare the effectiveness of innovative interventions led by older peers and which included a parent component with teacher-led interventions for nutrition, blood pressure, and smoking prevention. Information about the agreement between parents' and children's (grades six through eight) perception of the children's health behavior and family interaction was also found, by surveying parents and children in 1051 households. Both teacher-led and older peer-led interventions were successful in increasing behavioral capabilities for nutrition and blood pressure, measured one year after the interventions. Results of the parent-child survey showed reasonable agreement between parents and children for reports of the child's exercise, dieting, and fast food consumption, but poorer agreement for smoking and perceptions of family interaction. Results are discussed in relation to the planning of future programs designed to address the importance of peer and parental role models.

Government intervention programs in HIV/tuberculous infection. Outline of guidelines for national tuberculosis control programs in view of the HIV epidemic.

Tuberculosis is one of the most widespread infections known in the world. WHO estimates that in 1990, 1.7 billion people, or one third of the world population, are or have been infected with the tubercle bacillus. Fortunately, few of those infected develop active forms of the disease but it is estimated that in 1990, there will be 8 million new cases and 2.9 million deaths from tuberculosis in the world. This already alarming situation of the tuberculosis problem is getting worse, mainly due to the AIDS epidemic. A basic understanding of tuberculosis/HIV epidemiology is necessary and priority actions are to be strongly recommended for application in government intervention programs. They are specified in the present article.

Five-year findings of the hypertension detection and follow-up program. II. Mortality by race-sex and age. Hypertension Detection and Follow-up Program Cooperative Group.

Data are reported for four race-sex and three age subgroups of the Hypertension Detection and Follow-up Program (HDFP). Throughout the HDFP trial, for black men, black women, white men, and white women and for persons aged 30 to 49, 50 to 59, and 60 to 69 years at entry, control of blood pressure was consistently better for Stepped Care (SC) than Referred Care (RC) participants. This difference in degree of control was least for white women; it was less for whites than for blacks of the same sex. For white men, black men, and black women and for age subgroups 50 to 59 and 60 to 69 years, five-year all-cause death rates were substantially lower--by 15% to 28%--for the SC subgroups compared to the RC subgroups.

Nosocomial outbreaks: the Centers for Disease Control's Hospital Infections Program experience, 1980-1990. Epidemiology Branch, Hospital Infections Program.

From January 1980 to July 1990, the Hospital Infections Program of the Centers for Disease Control conducted 125 on-site epidemiologic investigations of nosocomial outbreaks. Seventy-seven (62%) were caused by bacterial pathogens, 11 (9%) were caused by fungi, 10 (8%) were caused by viruses, five (4%) were caused by mycobacteria, and 22 (18%) were caused by toxins or other organisms. The majority of fungi and mycobacterial outbreaks occurred since July 1985. Fourteen (11%) outbreaks were device related, 16 (13%) were procedure related, and 28 (22%) were product related. The proportion of outbreaks involving products, procedures, or devices increased from 47% during 1980-1985 to 67% between 1986 and July 1990. Recent outbreaks have shown that packed red blood cell transfusion-associated Yersinia enterocolitica sepsis results from contamination of the blood by the asymptomatic donor; that povidone-iodine solutions can become intrinsically contaminated and cause outbreaks of infection and/or pseudoinfection; and that rapidly growing mycobacteria can cause chronic otitis media, surgical wound infection, and hemodialysis-associated infections. These and other outbreaks demonstrate how epidemiologic and laboratory investigations can be combined to identify new pathogens and sources of infection and ultimately result in disease prevention.

Mortality findings for stepped-care and referred-care participants in the hypertension detection and follow-up program, stratified by other risk factors. The Hypertension Detection and Follow-up Program Cooperative Research Group.

Analyses of 5-year mortality data from the Hypertension Detection and Follow-up Program (HDFP) were performed with stratification according to several baseline traits. The HDFP participants were 10,940 white and black men and women ages 30-69 at baseline who were randomized to either stepped-care (SC) or referred-care (RC) groups. All-causes mortality rates were lower for the SC than the RC group, both overall and for the 90-104 mm Hg stratum, for both cigarette smokers and nonsmokers, and for persons with and without hypercholesterolemia, hyperglycemia, diagnosed diabetes, hyperuricemia, or rapid pulse rate. The SC group also fared better than RC for all strata of body mass index, with an apparent trend toward an inverse relationship between body mass index and degree of benefit. Several of the traits--cigarette smoking, fasting hyperglycemia, and hyperuricemia--were associated with significantly higher 5-year mortality rates in both SC and RC participants, in both univariate and multivariate analyses, and a significant U-shaped relationship was recorded between body mass index and mortality for both SC and RC groups. These findings indicate the broad benefit of vigorous antihypertensive stepped-care treatment for hypertensive patients regardless of the presence or absence of the other major risk factors. They also underscore the need for comprehensive management of persons with high blood pressure to control not only their hypertension but also other risk factors associated with negative impact on long-term prognosis.

RECPAM: a computer program for recursive partition and amalgamation for censored survival data and other situations frequently occurring in biostatistics. I. Methods and program features.

The methodology of recursive partition and amalgamation in biostatistics is presented and a FORTRAN program for its implementation, RECPAM, is described. RECPAM can be used to obtain classifications of patients according to several criteria commonly occurring in clinical biostatistics: an example is prognostic classification based on survival data. Classes are defined by simple statements, expressed in clinical terms, about predictor variables (e.g. prognostic factors). Special features of RECPAM are: the possibility of implementing a variety of classification criteria, the integration of recursive partition and amalgamation, and the availability of several strategies for constructing classification trees. A simple example to illustrate input and output features is given. The scope and flexibility of RECPAM will be illustrated in greater detail in a subsequent paper.

Prognostic value of serum creatinine and effect of treatment of hypertension on renal function. Results from the hypertension detection and follow-up program. The Hypertension Detection and Follow-up Program Cooperative Group.

The Hypertension Detection and Follow-up Program followed up 10,940 persons for 5 years in a community-based, randomized, controlled trial of treatment for hypertension. Participants were randomized to one of two treatment groups, stepped care and referred care. The primary end point of the study was all-cause mortality, with morbid events involving the heart, brain, and kidney as secondary end points. Loss of renal function, ascertained by a change in serum creatinine, was among these secondary events. Baseline serum creatinine concentration had a significant prognostic value for 8-year mortality. For persons with a serum creatinine concentration greater than or equal to 1.7 mg/dl, 8-year mortality was more than three times that of all other participants. The estimated 5-year incidence of substantial decline in renal function was 21.7/1,000 in the stepped-care group and 24.6/1,000 in the referred-care group. Among persons with a baseline serum creatinine level between 1.5 and 1.7 mg/dl, the 5-year incidence of decline was 113.3/1,000 (stepped care) and 226.6/1,000 (referred care) (p less than 0.01). The incidence of decline in renal function was greater in men, blacks, and older adults, as well as in those with higher entry diastolic blood pressure. Among persons with a baseline serum creatinine level greater than or equal to 1.7 mg/dl, serum creatinine concentration declined by 25% or more in 28.6% of stepped-care and 25.2% of referred-care participants. Although the incidence of clinically significant hypercreatininemia in a hypertensive population is low, an elevated serum creatinine concentration is a very potent independent risk factor for mortality. The slightly lower rate of development of hypercreatininemia and the higher rate of improvement in stepped-care compared with referred-care participants is consistent with the belief that aggressive treatment of hypertension may reduce renal damage and the associated increased risk of death.

Development of a collaborative geriatric program between the legal system and a social work-directed program of a community hospital.

This paper details the development of a unique program developed between a social work-directed service of a community hospital and the probate system. It documents the value of combining the skills of these two systems to enhance the care, service delivery and quality of life of older persons involved in conservatorship matters. It suggests that such models will become increasingly necessary as the American population ages.

Survival analysis in drug program evaluation. Part I. Overall program effectiveness.

Survivorship analysis is a statistical technique used here in a summative evaluation that compares outcome data from multiple-site methadone maintenance programs in three California counties. Multiple outcome measures were obtained from retrospective interviews with 297 heroin addicts 6-8 years after admission to treatment. These measures were rates of retention, incarceration, addiction, crime, dealing, and loss of employment. Survival curves for all six measures are consistent in showing that Los Angeles County had the best outcomes, followed by San Bernardino County and then Orange County.
