OBJECTIVE: To assess and compare alternative approaches of measuring preference-based health-related quality of life (HRQoL) in treatment-experienced HIV patients and evaluate their association with health status and clinical variables. DESIGN: Cross-sectional study.

SETTING: Twenty-eight Veterans Affairs hospitals in the United States, 13 hospitals in Canada, and 8 hospitals in the United Kingdom.

PATIENTS: Three hundred sixty-eight treatment-experienced HIV-infected patients enrolled in the Options in Management with Antiretrovirals randomized trial.

MEASUREMENTS: Baseline sociodemographic and clinical indicators and baseline HRQoL using the Medical Outcome Study HIV Health Survey (MOS-HIV), the EQ-5D, the EQ-5D visual analog scale (EQ-5D VAS), the Health Utilities Index Mark 3 (HUI3), and standard gamble (SG) and time trade-off (TTO) techniques. RESULTS: The mean (SD) baseline HRQoL scores were as follows: MOS-HIV physical health summary score 41.70 (11.16), MOS-HIV mental health summary score 44.76 (11.38), EQ-5D 0.77 (0.19), HUI3 0.59 (0.32), EQ-5D VAS 65.94 (21.71), SG 0.75 (0.29), and TTO 0.80 (0.31). Correlations between MOS-HIV summary scores and EQ-5D, EQ-5D VAS, and HUI3 ranged from 0.60 to 0.70; the correlation between EQ-5D and HUI3 was 0.73; and the correlation between SG and TTO was 0.43. Preference-based HRQoL scores were related to physical, mental, social, and overall health as measured by MOS-HIV. Concomitant medication use, CD4 cell count, and HIV viral load were related to some instruments' scores.

CONCLUSIONS: On average, preference-based HRQoL for treatment-experienced HIV patients was decreased relative to national norms but also highly variable. Health status and clinical variables were related to HRQoL.

BACKGROUND: Concern about patient safety has promoted efforts to improve safety climate. A better understanding of how patient safety climate differs among distinct work areas and disciplines in hospitals would facilitate the design and implementation of interventions. OBJECTIVES: To understand workers' perceptions of safety climate and ways in which climate varies among hospitals and by work area and discipline. RESEARCH DESIGN: We administered the Patient Safety Climate in Healthcare Organizations survey in 2004-2005 to personnel in a stratified random sample of 92 US hospitals. SUBJECTS: We sampled 100% of senior managers and physicians and 10% of all other workers. We received 18,361 completed surveys (52% response). MEASURES: The survey measured safety climate perceptions and worker and job characteristics of hospital personnel. We calculated and compared the percent of responses inconsistent with a climate of safety among hospitals, work areas, and disciplines. RESULTS: Overall, 17% of responses were inconsistent with a safety climate. Patient safety climate differed by hospital and among and within work areas and disciplines. Emergency department personnel perceived worse safety climate and personnel in nonclinical areas perceived better safety climate than workers in other areas. Nurses were more negative than physicians regarding their work unit's support and recognition of safety efforts, and physicians showed marginally more fear of shame than nurses. For other dimensions of safety climate, physician-nurse differences depended on their work area. CONCLUSIONS: Differences among and within hospitals suggest that strategies for improving safety climate and patient safety should be tailored for work areas and disciplines.

The American College of Physicians (ACP) developed this guidance statement to present the available evidence on screening for HIV in health care settings. METHODS: This guidance statement is derived from an appraisal of available guidelines on screening for HIV. Authors searched the National Guideline Clearinghouse to identify guidelines on screening for HIV in the United States and used the AGREE (Appraisal of Guidelines Research and Evaluation) instrument to evaluate guidelines from the U.S. Preventive Services Task Force and the Centers for Disease Control and Prevention. GUIDANCE STATEMENT 1: ACP recommends that clinicians adopt routine screening for HIV and encourage patients to be tested. GUIDANCE STATEMENT 2: ACP recommends that clinicians determine the need for repeat screening on an individual basis.

Russia has one of the world's fastest growing HIV epidemics, and HIV screening has been widespread. Whether such screening is an effective use of resources is unclear. We used epidemiologic and economic data from Russia to develop a Markov model to estimate costs, quality of life and survival associated with a voluntary HIV screening programme compared with no screening in Russia. We measured discounted lifetime health-care costs and quality-adjusted life years (QALYs) gained. We varied our inputs in sensitivity analysis. Early identification of HIV through screening provided a substantial benefit to persons with HIV, increasing life expectancy by 2.1 years and 1.7 QALYs. At a base-case prevalence of 1.2%, once-per-lifetime screening cost $13,396 per QALY gained, exclusive of benefit from reduced transmission. Cost-effectiveness of screening remained favourable until prevalence dropped below 0.04%. When HIV-transmission-related costs and benefits were included, once-per-lifetime screening cost $6910 per QALY gained and screening every two years cost $27,696 per QALY gained. An important determinant of the cost-effectiveness of screening was effectiveness of counselling about risk reduction. Early identification of HIV infection through screening in Russia is effective and cost-effective in all but the lowest prevalence groups.

Study objective

There is increasing concern that decreasing reimbursements to emergency departments (EDs) will negatively affect their functioning, but little evidence has been published identifying trends in reimbursement rates. We seek to examine and document the trends in reimbursement for outpatient ED visits throughout the past decade.

Methods

We use Medical Expenditure Panel Survey data covering a 9-year span from 1996 to 2004, using outpatient ED visits as the unit of analysis. Our primary outcome variables were total and per-visit charges and payments across insurance. Using regression analyses with a generalized linear models approach, we also derived the adjusted mean payment and mean charge for each ED visit, as well as the average payment ratio.

Results

Overall, adjusted mean charges for an outpatient ED visit increased from $713 (95% confidence interval [CI] $665 to $771) in 1996 to $1,390 (95% CI $1,317 to $1,462) in 2004. The adjusted mean payment also increased from $410 (95% CI $366 to $453) in 1996 to $592 (95% CI $551 to $634) in 2004. Because payments increased at a slower rate in all payer groups compared with charges, the overall share of charges that were paid decreased over time from 57% in 1996 (n=3,433) to 42% in 2004 (n=5,763; P<.001). The proportion of total charges paid in 2004 was highest for privately insured visits (56%; n=2,005) and lowest for Medicaid visits (33%; n=1,618). For visits by uninsured patients (n=996), 35% of charges were paid in 2004.

Conclusion

The proportion of charges paid for outpatient ED visits from Medicaid, Medicare, and privately insured and uninsured patients persistently decreased from 1996 to 2004. These concerning decreases may threaten the survival of EDs and their ability to continue to provide care as safety nets in the US health care system.

ABSTRACT

Control of infectious diseases is a key global health priority. This paper describes the role that simulation can play in evaluating policies for infectious disease control. We describe ongoing simulation studies in three different areas: HIV prevention and treatment, contact tracing, and hepatitis B prevention and control.

OBJECTIVE. The purpose of our work was to determine whether children with very low birth weight (<1500 g) who are at high risk for vision and hearing problems and enrolled in Medicaid receive recommended follow-up vision and hearing services and to examine predictors of services.

PATIENTS AND METHODS. We conducted a retrospective analysis of 2182 children born in South Carolina from 1996 to 1998 with birth weights of 401 to 1499 g, gestations of ≥24 weeks, and survival of ≥90 days of life. Receipt of services for Medicaid-enrolled children was assessed by using a linked data set that included files from vital records, death certificates, Medicaid, Chronic Rehabilitative Services, and the Early Intervention Program. We assessed the receipt of hearing rehabilitation by 6 months of age for children with nonconductive hearing loss and routine ophthalmologic examination between ages of 1 and 2 years for all children with very low birth weight. Multivariate logistic regression was restricted to ophthalmologic examinations because of sample size.

RESULTS. Among children with very low birth weight with nonconductive hearing loss, 20% received hearing rehabilitation by 6 months of age. Twenty-three percent of children with very low birth weight received an ophthalmologic examination between the ages of 1 and 2 years. Limiting our analysis to children <1000 g or extending the measurement period to 7 months (hearing) and age 3 years (vision) did not substantially increase the percentage of children receiving the services. The receipt of an ophthalmologic examination was associated positively with Medicaid enrollment by the time of hospital discharge and birth in a level-3 hospital and negatively associated with higher birth weight, an Apgar score of ≥7, and black maternal race. Among children born at <1000 g, all of whom were eligible for the Early Intervention Program, the receipt of an ophthalmologic examination was positively associated with program enrollment.

CONCLUSIONS. There is a shortfall in the provision of critical services for children with very low birth weight. These findings reinforce the Institute of Medicine's concerns regarding inadequate outcome data and health care services for preterm infants and support the importance of enrollment in the Early Intervention Program for children with very low birth weight.

In late 2006, the Chinese government appointed a high-level inter-ministerial commission—composed of fourteen government agencies, co-chaired by the National Development and Reform Commission and the Ministry of Health—to develop a blueprint for China’s healthcare system. One party to that process, China’s Insurance Regulatory Commission (CIRC), has developed a program of cooperation with its U.S. counterpart, the National Association of Insurance Commissioners (NAIC). To provide input to policymaking, representatives of CIRC, NAIC, private insurers in China and the United States, as well as Chinese and American scholars of health insurance gathered in Yichang, Hubei, PRC, on 18-19 June 2007, for a joint seminar on the role of commercial health insurance in the Chinese and U.S. healthcare systems.

The first section of this field report provides a brief description of China’s health care reforms in the past decades. The second section highlights the progress and challenges to date in developing commercial health insurance in China, and the final section summarizes the recommendations that the NAIC Commissioners provided to CIRC in 2007 at this critical juncture in China’s health policy reforms.

OBJECTIVES: In response to growing concerns about sexual violence as an underrecognized traumatic consequence of military service, Veterans Health Administration policy requires universal screening for sexual trauma sustained during military service. This prospective study, the first to evaluate national efforts to screen for military sexual trauma, investigated whether sexual trauma screening is associated with increased utilization of mental health services.

METHODS: This study examined data for all male (N=540,381) and female (N=33,259) veterans who had valid responses to screens for military sexual trauma in 2005. The use of mental health services during the three months after screening was examined for persons who screened positive for military sexual trauma and for those who screened negative. Findings were stratified by use of mental health services in the six months before the screening.

RESULTS: Compared with negative screens, positive screens were associated with significantly increased rates of postscreen mental health treatment. A more than twofold increase was observed for patients without previous use of mental health treatment (women: relative risk [RR]=2.52, 95% confidence interval [CI]= 2.38–2.66; men: RR=2.47, 95% CI=2.34–2.61). In this group, the number of positive screens needed for one additional patient to access treatment was 5.5 for women and 7.2 for men.

CONCLUSIONS: Our findings suggest that detection via screening is associated with increased rates of mental health treatment. An effective screening program that promotes detection of sexual trauma and access to mental health care can help to reduce the burden of psychiatric illness for those who have experienced military sexual trauma.
