An epidemiological and economic simulation model to evaluate the spread and control of infectious bovine rhinotracheitis in The Netherlands.

Bovine herpesvirus type I (BHV1), causing infectious bovine rhinotracheitis (IBR), was introduced in the Netherlands in 1971. In 1993, about 42% of the dairy cows had antibodies against BHV1. In the future, stricter requirements are anticipated regarding the health status of exported breeding cows and material. To support policymakers in their decisions on IBR eradication, a simulation model was developed in which the epidemiological and economic consequences of various control strategies were evaluated. This paper describes the model and provides an overview of some important outcomes. In the model, dairy herds were classified into different disease states based on (1) the reproduction ratio of the disease (R, defined as the number of secondary cases caused by one infectious animal) (2) the within-herd prevalence, within each value of R and (3) the expected number of infectious animals in an infectious herd within each prevalence range. The dynamic transition probability of a herd going from one state to another per week depends on direct contacts between animals, and other contacts such as transmission through fomites, indirect transmission through other species, airborne transmission and minor disease-specific routes such as venereal or iatrogenic transmission. Five control strategies, including both a voluntary vaccination program and a compulsory vaccination program for all dairy herds were evaluated. A voluntary vaccination program with 50% participation is not expected to lead to eradication of IBR. It appears that compulsory vaccination would be necessary to reach an IBR-free status.

Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (PRWORA); interpretation of "federal public benefit"--HHS. Notice with comment period.

This notice with comment period interprets the term "Federal public benefit" as used in Title IV of the Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (PRWORA), Pub. L. 104-193, and identifies the HHS programs that provide such benefits under this interpretation. According to section 401 if PRWORA, aliens who are not "qualified aliens" are not eligible for any "Federal public benefit," unless the "Federal public benefit" falls within a specified exception. A "Federal public benefit" includes "any grant, contract, loan, professional license, or commercial license" provided to an individual, and also "any retirement, welfare, health, disability, public or assisted housing, postsecondary education, food assistance, unemployment benefit, or any other similar benefit for which payments or assistance are provided to an individual, household, or family eligibility unit." Under section 432, providers of a non-exempt "Federal public benefit" must verify that a person applying for the benefit is a qualified alien and is eligible to receive the benefit. The HHS programs that provide "Federal public benefits" and are not otherwise excluded from the definition by the exceptions provided in section 401(b) are: Adoption Assistance Administration on Developmental Disabilities (ADD)-State Developmental Disabilities Councils (direct services only) ADD-Special Projects (direct services only) ADD-University Affiliated Programs (clinical disability assessment services only) Adult Programs/Payments to Territories Agency for Health Care Policy and Research Dissertation Grants Child Care and Development Fund Clinical Training Grant for Faculty Development in Alcohol & Drug Abuse Foster Care Health Profession Education and Training Assistance Independent Living Program Job Opportunities for Low Income Individuals (JOLI) Low Income Home Energy Assistance Program (LIHEAP) Medicare Medicaid (except assistance for an emergency medical condition) Mental Health Clinical Training Grants Native Hawaiian Loan Program Refugee Cash Assistance Refugee Medical Assistance Refugee Preventive Health Services Program Refugee Social Services Formula Program Refugee Social Services Discretionary Program Refugee Targeted Assistance Formula Program Refugee Targeted Assistance Discretionary Program Refugee Unaccompanied Minors Program Refugee Voluntary Agency Matching Grant Program Repatriation Program Residential Energy Assistance Challenge Option (REACH) Social Services Block Grant (SSBG) State Child Health Insurance Program (CHIP) Temporary Assistance for Needy Families (TANF) While all of these programs provide "Federal public benefits" this does not mean that all benefits or services provided under these programs are "Federal public benefits." As discussed in sections II and III below, some benefits or services under these programs may not be provided to an "individual, household, or family eligibility unit" and, therefore, do not constitute "Federal public benefits" as defined by PRWORA.

The case against compulsory casefinding in controlling AIDS--testing, screening and reporting.

The spread of acquired immune deficiency syndrome (AIDS) demands a comprehensive and effective public health response. Because no treatment or vaccine is currently available, traditional infection control measures are being considered. Proposals include compulsory testing and screening of selected high risk populations. The fairness and accuracy of compulsory screening programs depend upon the reliability of medical technology and the balancing of public health and individual confidentiality interests. This Article proposes criteria for evaluating compulsory testing and screening programs. It concludes that voluntary identification, education, and counselling of infected persons is the most effective means of encouraging the behavioral changes that are necessary to halt the spread of AIDS.

Follow-up of rapists treated in a forensic psychiatric hospital.

Current research examining the effectiveness of sex offender treatment is encouraging. Despite this optimism, research focusing on men who sexually assault adult women is less optimistic. This study examines the preliminary results of 74 rapists admitted into the Phoenix program, a voluntary sex offender treatment program in a forensic psychiatric hospital. Patients were categorized according to whether they completed treatment or not. Treated rapists (n = 36) reoffended at a substantially lower rate than untreated rapists who were assessed but not treated (n = 38). Statistically significant differences in reoffense rates were found for violent, nonsexual offenses as well as nonviolent, nonsexual offenses. Although nearly twice as many treatment noncompleters reoffended sexually, the difference between the two groups was not statistically significant. Mean follow-up time was well over four years for both groups. The implications of these findings are discussed.

Economic impact of treatment of HIV-positive pregnant women and their newborns with zidovudine. Implications for HIV screening.

OBJECTIVES: To estimate the economic impact of (1) treating pregnant women who are human immunodeficiency virus (HIV)-positive with zidovudine and (2) voluntary screening programs for pregnant women for HIV infection and offering treatment with zidovudine to those found to be HIV-positive. MAIN OUTCOME MEASURES: Number of cases of pediatric HIV infection and costs of screening, zidovudine treatment, and pediatric HIV infection treatment. DESIGN: Health care costs associated with treatment of HIV-positive pregnant women and their newborns are estimated as the costs of zidovudine and its administration and the reduction in costs of treating pediatric HIV infection. The lifetime costs of pediatric HIV infection are derived from the published literature. Estimates of the reduction in maternal-to-fetal transmission rates are taken from the AIDS [acquired immunodeficiency syndrome] Clinical Trials Group (ACTG) Protocol 076. Costs of a voluntary screening program include costs of screening tests and counseling. Sensitivity and threshold analyses are performed to determine the impact of changes in input parameter values including zidovudine treatment costs, efficacy of treatment, costs of pediatric HIV infection, prevalence of HIV infection in pregnant women, screening test sensitivity and specificity, and pregnancy termination rates on the results. RESULTS: Assuming transmission rates are reduced from 25.5% to 8.3% as found in the ACTG 076 trial, treatment costs of $104,502 for 100 HIV-positive pregnant women and their newborns are offset by the reduction of $1,701,333 associated with fewer cases of pediatric HIV infection for a net savings of $1,596,831. The sensitivity and threshold analyses show that overall cost savings from treatment of HIV-positive pregnant women and their newborns are achieved for a wide range of possible maternal treatment costs, efficacy rates, and lifetime pediatric HIV treatment costs. In the base-case analysis for the voluntary screening program, overall cost savings are seen when HIV prevalence rate among pregnant women is greater than 4.6 per 1000. However, this threshold prevalence rate is sensitive to changes In parameter value-especially pediatric HIV treatment costs, counselling costs, efficacy of treatment, and years of additional HIV treatment for the pregnant women. CONCLUSIONS: Offering zidovudine treatment to pregnant women known to be HIV-positive will decrease the number of cases of pediatric HIV infection and reduce health care costs. Voluntary screening programs for pregnant women will further decrease the number of cases of pediatric HIV infection. The effect of a screening program on health care costs varies according to HIV prevalence and the costs associated with the screening program.

Prenatal HIV screening in pregnant women: a medical-legal review.

Identifying pregnant women's human immunodeficiency virus (HIV) infection status provides them with the opportunity to seek appropriate treatment and to take measures to prevent vertical and horizontal transmission. Prenatal screening program options include targeting at-risk women, testing on a voluntary basis, or mandating prenatal HIV screening. When examining these options, the number of cases identified, programmatic costs, long-term health care costs, and legal implications must all be considered. Research indicates that targeting at-risk women misses a significant percentage of seropositive women, although programmatic costs may be lower. It is difficult to ascertain the difference between voluntary and mandatory programs with respect to the number of cases identified and treated. As a result, long-term savings are difficult to calculate. Mandatory programs would have the greatest direct costs and place the greatest burden on the woman's constitutional rights. By making HIV counseling and testing a routine component of prenatal care, voluntary programs could achieve the benefits of prenatal HIV screening without violating the woman's civil liberties.

Enalapril to lisinopril: economic impact of a voluntary angiotensin-converting enzyme-inhibitor substitution program in a staff-model health maintenance organization.

OBJECTIVE: The cost-effectiveness of a voluntary program that switched enalapril to lisinopril therapy in patients with benign essential hypertension in a staff-model health maintenance organization (HMO) was evaluated. DESIGN: The one-year nonrandomized, controlled trial was performed from November 1989 through October 1990. PARTICIPANTS: One hundred twenty-seven patients were entered into the study: 75 who converted from enalapril to lisinopril and 52 who remained on enalapril throughout the study period. Patients were excluded from analysis because of diagnosis (not benign essential hypertension) or insufficient data collection. INTERVENTIONS: Patients taking enalapril were asked by staff pharmacists if they were willing to consider switching from enalapril to lisinopril. To encourage patients, the HMO agreed to waive the drug rider copayment for three months. If patients were willing, their physicians were contacted and they established the lisinopril dosage. MAIN OUTCOME MEASURES: Total direct cost and savings resulting from converting patients from enalapril to lisinopril were measured and compared with costs of therapy for patients who remained on enalapril. RESULTS: The control and study groups were evenly matched according to demographics and concomitant drug therapy. Drug acquisition costs, costs associated with waiving drug rider copayment, pharmacy administrative costs, costs of managing adverse events, costs of visits to physicians, and laboratory test costs were assessed. Depending on the cost of capital assumed, net savings ranged from $85 to $110 per patient converted from enalapril to lisinopril. Monthly net savings that ranged from $2.04 to $2.61 per patient were required to result in overall net savings within the first two years. CONCLUSIONS: In a regular practice setting, a net savings is realized in less than 12 months when patients are converted from enalapril to lisinopril for treatment of benign essential hypertension. The voluntary therapeutic interchange program provided a good means for achieving cost controls for pharmacy expenses.

The complexities of managed care: operating a voluntary system.

The implementation of state-sponsored voluntary case management programs for public assistance recipients creates provider and recipient recruiting problems that are unique to the state's economic environment, its political climate, its historic relationship with providers, its program goals, and its implementation strategies. This implementation study discusses the factors that influenced the operationalization of the Massachusetts managed care program for AFDC families. The issues of provider recruitment and recipient enrollment are examined in relation to the formal program goals of cost containment and access. The operational and bureaucratic problems the state Medicaid staff has experienced in maintaining the program evokes questions of who should administer the programs, who the best types of providers are in light of program goals, and how recipients can be enrolled in a voluntary program.

Legal and ethical issues relating to AIDS.

The worldwide AIDS epidemic has posed an extraordinary array of ethical and legal challenges. The work presented here reviews three issues at the heart of the matter: discrimination against HIV-infected people, the limits of confidentiality, and the exercise of coercive government powers to limit spread of the disease. Because the authors are most familiar with the U.S. experience, the review deals primarily with the history of the epidemic in the United States and public responses to it in that country.

The costs of employee smoking. A computer simulation of hospital nurses.

A computer simulation model of the economic impact of employee smoking on an employer was developed with a population of hospital nurses as the example. Net economic impact was calculated by estimating cumulative costs borne by the employer under various scenarios and comparing them with projected costs estimated from baseline data. The model included the following: baseline number of staff, baseline percentage of smokers, annual employee turnover rate, number of smokers interested in quitting, the cost of a smoking cessation program, expected success rate of a voluntary cessation program, smokers quitting spontaneously without a program, and employer-borne costs related to employee smoking. A variety of scenarios were constructed to generate a range of employer net economic impact figures and resulting percentages of smoking employees. Results showed that the benefits of a cessation program would be eliminated over several years, unless the prevalence of smoking in incoming employees was reduced. The most favorable scenario, combining a hospital cessation program and reduced smoking among new employees, generated cumulative savings, discounted at 5%, of $358,000 to $684,000 over an eight-year period.
