Seroconversion rates in healthcare workers using a latex agglutination assay after varicella virus vaccination.

OBJECTIVES: To determine the seroconversion rate after varicella immunization of healthcare workers (HCWs) and the effect of seroconversion rate on current cost-based recommendations for universal vaccination. METHODS: A voluntary vaccination program for HCWs was performed at a tertiary-care cancer center in New York City. A commercial latex agglutination assay was used to test postvaccination antibody response. Costs for vaccination and postvaccination serological testing were compared to potential costs of postexposure employee furloughs. RESULTS: Of 263 seronegative HCWs, 96 (36.5%) began the vaccine program. Thirty-nine HCWs received only one dose of vaccine. Seven returned for follow-up antibody testing, of whom 4 were seropositive. Of the 57 HCWs who received two doses, 38 returned for follow-up serology. Thirty-one (81.6%) HCWs were seropositive for varicella-zoster virus antibodies, and seven HCWs (18.4%) remained seronegative. Total cost of vaccination for all 263 seronegative HCWs was estimated and compared to the cost of varicella-related furloughs at our institution. CONCLUSIONS: We found a considerably lower rate of vaccine-induced seroconversion at our hospital compared to that of the published literature. Despite this finding, universal varicella vaccination remained an extremely cost-effective alternative to the furloughing of exposed, seronegative HCWs. Projected hospital savings exceeded $53,000 in the first year after vaccination alone.

Community-based health insurance in low-income countries: a systematic review of the evidence.

Health policy makers are faced with competing alternatives, and for systems of health care financing. The choice of financing method should mobilize resources for health care and provide financial protection. This review systematically assesses the evidence of the extent to which community-based health insurance is a viable option for low-income countries in mobilizing resources and providing financial protection. The review contributes to the literature on health financing by extending and qualifying existing knowledge. Overall, the evidence base is limited in scope and questionable in quality. There is strong evidence that community-based health insurance provides some financial protection by reducing out-of-pocket spending. There is evidence of moderate strength that such schemes improve cost-recovery. There is weak or no evidence that schemes have an effect on the quality of care or the efficiency with which care is produced. In absolute terms, the effects are small and schemes serve only a limited section of the population. The main policy implication of the review is that these types of community financing arrangements are, at best, complementary to other more effective systems of health financing. To improve reliability and validity of the evidence base, analysts should agree on a more coherent set of outcome indicators and a more consistent assessment of these indicators. Policy makers need to be better informed as to both the costs and the benefits of implementing various financing options. The current evidence base on community-based health insurance is mute on this point.

Community bioethics: the health decisions community council.

Health care decision making in modern society can pose a variety of complex issues for consideration by individuals, families, and providers. The Health Decisions Community Council (HDCC), a community-based bioethics committee, was established to offer a noninstitutional forum for discussion of difficult health care dilemmas. Social work skills and values for autonomy and self-determination are essential to the formation of the HDCC as a model for community bioethics discussions.

Ought the young make health care decisions for their aged selves?

Though the chief responsibility for providing for the health care of older Americans has been (and should remain) society's, there has been increasing interest in private solutions. Individual provision, however, would require not only adequate wealth but prudent planning, demanding in turn more discipline, self-control, and foresightedness than many individuals are normally capable of. One possible corrective is pre-commitment, a strategy of binding oneself to a plan chosen to allocate resources optimally over the life span. Though pre-commitment may have some important uses, however, it is far from clear that people should be encouraged or enabled to rely upon it for old-age health care planning. The present paper examines some of the philosophical and policy concerns attendant to the use of pre-commitment strategies for resource allocation in old age.

Universal health care coverage--pitfalls and promise of an employment-based approach.

America's patchwork quilt of health care coverage is coming apart at the seams. The system, such as it is, is built upon an inherently problematic base: employment. By definition, an employment-based approach, by itself, will not assure universal coverage of the entire population. If an employment-based approach is to be the centerpiece of a system that provides universal coverage, special attention must be paid to all the categories of individuals who are not employees--children, unemployed spouses or singles, the unemployable ill and disabled, persons between jobs, students, retirees, the elderly. Moreover, in a purely voluntary employment-based arrangement, some employers will not provide insurance at all, and others will provide inadequate coverage, necessitating other special provisions for coverage. As a consequence, about one out of six people now has no health coverage whatsoever, and even more have inadequate coverage. All the while, the rapidly-increasing transaction costs of sustaining this grossly inadequate pluralistic system eat up sufficient funds to provide basic benefits to the entire population. The time for systematic reforms has come and gone; what is now needed is action to prevent disaster, followed by a complete rebuilding of this country's health coverage system. Although perhaps more likely to be tried than more radical, completely nationalized, ones, stepwise reforms may not go far enough to cure the significant ills of the current employment-based system. Passage of inadequate reforms, then, could well set the stage for nationalized health care in the not too distant future.

The give and take of organ procurement.

Scientific developments of the last 20 years have made the transplantation of cadaveric solid organs a viable and expected treatment alternative for patients suffering from various forms of End Stage Organ Disease. Of the number of organs that could be utilized for this, only a small percentage of them are actually made available. North American legislation explicitly categorizes the transfer of cadaveric organs as an anatomical or tissue "gift". The concept of the gift is mediated by transculturally consistent unwritten, but powerfully felt, rules of conduct. Among the most profound elements of the concept is the obligatory gift-exchange which is central to the gift-relationship. Obviously, neither of these are permitted by the organ transplant scenario. As a result, dissonance is created within the thought process of the individual which cannot be easily resolved, paralyzing many into inaction. We maintain that the present legal framework, designed to facilitate the transfer of organs, clashes with the human phenomenon of giving, and may actually prevent organs from being made available. In a search for a solution to this gift-relationship dilemma, giving organs is contrasted with taking organs as a basis upon which to ground ethically sound public policy. Liberty-limiting principles and the concept of harm are considered within this context.

Informed consent and anonymous tissue samples: the case of HIV seroprevalence studies.

Human Immunodeficiency Virus (HIV) seroprevalence studies use anonymous tissue samples obtained in hospitals and clinics without donor consent. This can be justified as a response to a public health emergency, but should not be seen as setting a precedent for waiving consent whenever samples are anonymous. The following recommendations grow out of this discussion: (1) Studies using anonymous tissue samples should not be automatically exempt from consent requirements, and consent should not be waived simply to avoid anticipated refusals, low participation rates or self selection bias. (2) The consensus on informed consent favors fulfilling as many of the elements of informed consent as reasonably possible, so studies should be assessed individually to determine if any or all elements of informed consent should be modified or omitted. (3) There is a need for greater regulation of the research use of tissue samples. (4) Investigators seeking approval to waive consent or modify elements of informed consent should document the sort of new findings that they believe would effect their calculations about the benefits and burdens to subjects who are enrolled in the study, and institutional review boards should indicate whether they agree with the investigators' analysis.

Voluntary testing for human immunodeficiency virus (HIV) in a prison population with a high prevalence of HIV.

This study evaluated voluntary testing for human immunodeficiency virus (HIV) in a prison population with a high HIV seroprevalence. Data on demographic variables and participation in voluntary testing were linked to a blinded HIV serosurvey of consecutive Maryland prison entrants (April-July 1991). Among 2,842 entrants, HIV seroprevalence was 8.5% (men, 7.9%; women, 15.3%). Voluntary testing was accepted by 47% of the entrants, and it identified 34% of the HIV-seropositive inmates detected by serosurvey. Refusers of testing were more likely to test HIV-seropositive than were accepters (adjusted odds ratio (OR) = 1.84, 95% confidence interval (CI) 1.58-2.16). Refusers and accepters of testing had similar risk factors for HIV infection, chiefly current syphilis infection (adjusted OR = 5.96, 95% CI 3.15-10.27) and prior injected drug use (adjusted OR = 4.26, 95% CI 3.15-5.76). Among 100 entrants asked why they refused testing, primary reasons given included low risk of HIV, fear of testing HIV-seropositive, and lack of interest. Voluntary testing appears only moderately successful in identifying HIV-seropositive inmates in a high-seroprevalence prison population. However, the alternative, mandatory HIV testing of prisoners, can be construed as discriminatory and unethical when similar screening is not imposed on the population at large. Data presented here suggest strategies to improve acceptance of voluntary testing, especially by high risk inmates.

Effect of laboratory error on the identification of persons with hypercholesterolemia in an employee health service.

Cholesterol is a major risk factor for coronary heart disease. Of 117 employees seen consecutively in the Tennessee State Employee Health Service voluntary screening program, 86 (74%) had cholesterol levels above the reference range reported by a commercial clinical laboratory. This was three times greater than the calculated expected number of 29 (25%, 17 at moderate risk, 12 at high risk for coronary disease). Age and sex adjustment using Lipid Research Clinic guidelines reduced the number with elevated cholesterol to 55 (47%, 24 at moderate risk, 31 at high risk). Split sample cholesterol assays run independently by the commercial laboratory and a university laboratory showed excellent correlation (r = 0.99, commercial laboratory = 1.0 (university laboratory) + 10.8), but a systematic difference of 12.4 mg/dL (SD = 6.4 mg/dL, paired-t = 9.63, p less than 0.00001) between the two laboratories. Further adjustment for this difference reduced the number with elevated cholesterol to 41 (36%, 26 at moderate risk, 15 at high risk). This experience illustrates how small systematic laboratory errors in cholesterol determination can greatly exaggerate the number of persons reported to have clinically important cholesterol elevations. Clinical laboratories should report age and sex adjusted cholesterol reference ranges and provide clients periodic quality assurance reports that their measurements of cholesterol levels are accurate.

Assessing pediatric anesthesia practices for volunteer medical services abroad.

BACKGROUND: Anesthetic techniques and problems in volunteer medical services abroad are different from those of either the developed countries from which volunteers originate or the host country in which they serve because of differences in patient population, facilities, and goals for elective surgery. Assessing outcomes is hampered by the transience of medical teams and the global dispersion of providers. We studied general anesthesia techniques and outcomes in a large international voluntary surgical program. METHODS: Anesthesia providers and nurses participating in care of patients undergoing reconstructive plastic and orthopedic surgery by Operation Smile over an 18-month period were asked to complete a quality assurance data record for each case. Incomplete data were supplemented by reviewing the original patient records. RESULTS: General anesthesia was used in 87.1% of the 6,037 cases reviewed. The median age was 5 yr (25th-75th percentiles: 2-9 yr). Orofacial clefts accounted for more than 80% of procedures. Halothane mask induction was performed in 85.6% of patients; 96.3% of patients had tracheal intubation, which was facilitated with a muscle relaxant in 19.3%. Respiratory complications occurred during anesthesia in 5.0% of patients and during recovery (postanesthesia care unit) in 3.3%. Arrhythmias requiring therapy occurred in 1.5%, including three patients to whom cardiopulmonary resuscitation was administered. Prolonged ventilatory support was required in seven patients. There was one death. Inadvertent extubation during surgery occurred in 38 patients. Cancellation of surgery after induction of anesthesia occurred in 25 patients. Overall, complications were more common in younger children. CONCLUSIONS: Our study showed that in this setting it is feasible to track anesthesia practice patterns and adverse perioperative events. We identified issues for further examination.

Voluntary counselling, HIV testing and adjunctive cotrimoxazole reduces mortality in tuberculosis patients in Thyolo, Malawi.

OBJECTIVES: To assess the feasibility and effectiveness of voluntary counselling, HIV testing and adjunctive cotrimoxazole in reducing mortality in a cohort of tuberculosis (TB) patients registered under routine programme conditions in a rural district of Malawi. DESIGN: 'Before' and 'after' cohort study using historical controls. METHODS: Between 1 July 1999 and 30 June 2000 all TB patients were started on standardized anti-TB treatment, and offered voluntary counselling and HIV testing (VCT). Those found to be HIV-positive were offered cotrimoxazole at a dose of 480 mg twice daily, provided there were no contraindications. Side-effects were monitored clinically. End-of-treatment outcomes in this cohort (intervention group) were compared with a cohort registered between 1 July 1998 and 30 June 1999 in whom VCT and cotrimoxazole was not offered (control group). FINDINGS: A total of 1986 patients was registered in the study: 1061 in the intervention group and 925 in the control cohort. In the intervention group, 1019 (96%) patients were counselled pre-test, 964 (91%) underwent HIV testing and 938 (88%) were counselled post-test. The overall HIV-seroprevalence rate was 77%. A total of 693 patients were given cotrimoxazole of whom 14 (2%) manifested minor dermatological reactions. The adjusted relative risk of death in the intervention group compared with the control group was 0.81 (P < 0.001). The number needed to treat with VCT and adjunctive cotrimoxazole to prevent one death during anti-TB treatment was 12.5. INTERPRETATION: This study shows that VCT and adjunctive cotrimoxazole is feasible, safe and reduces mortality rates in TB patients under routine programme conditions.

Routine voluntary antepartum HIV antibody counseling and testing: a sound public health prevention strategy.

Routine voluntary antepartum HIV antibody counseling and testing are important HIV prevention strategies based on sound public health principles. The ultimate goal of this testing strategy is two-fold: identification of high-risk seronegative women for risk reduction counseling; and identification of HIV-infected parturients for counseling, prenatal care, and long-term medical management. To achieve these objectives, there must be nationwide implementation of the CDC HIV prenatal testing guidelines. Our challenge as healthcare providers is to ensure that all of our prenatal patients are afforded the opportunity to have HIV counseling and testing performed.
