Background The Botswana government recently implemented a policy of routine or “opt-out” HIV testing in response to the high prevalence of HIV infection, estimated at 37% of adults. Methods and Findings We conducted a cross-sectional, population-based study of 1,268 adults from five districts in Botswana to assess knowledge of and attitudes toward routine testing, correlates of HIV testing, and barriers and facilitators to testing, 11 months after the introduction of this policy. Most participants (81%) reported being extremely or very much in favor of routine testing. The majority believed that this policy would decrease barriers to testing (89%), HIV-related stigma (60%), and violence toward women (55%), and would increase access to antiretroviral treatment (93%). At the same time, 43% of participants believed that routine testing would lead people to avoid going to the doctor for fear of testing, and 14% believed that this policy could increase gender-based violence related to testing. The prevalence of self-reported HIV testing was 48%. Adjusted correlates of testing included female gender (AOR = 1.5, 95% CI = 1.1–1.9), higher education (AOR = 2.0, 95% CI = 1.5–2.7), more frequent healthcare visits (AOR = 1.9, 95% CI = 1.3–2.7), perceived access to HIV testing (AOR = 1.6, 95% CI = 1.1–2.5), and inconsistent condom use (AOR = 1.6, 95% CI = 1.2–2.1). Individuals with stigmatizing attitudes toward people living with HIV and AIDS were less likely to have been tested for HIV/AIDS (AOR = 0.7, 95% CI = 0.5–0.9) or to have heard of routine testing (AOR = 0.59, 95% CI = 0.45–0.76). While experiences with voluntary and routine testing overall were positive, 68% felt that they could not refuse the HIV test. Key barriers to testing included fear of learning ones status (49%), lack of perceived HIV risk (43%), and fear of having to change sexual practices with a positive HIV test (33%). Conclusions Routine testing appears to be widely supported and may reduce barriers to testing in Botswana. As routine testing is adopted elsewhere, measures should be implemented to assure true informed consent and human rights safeguards, including protection from HIV-related discrimination and protection of women against partner violence related to testing.

PURPOSE As the United States population ages, the increasing prevalence of cancer is likely to result in higher direct medical and nonmedical costs. Although estimates of the associated direct medical costs exist, very little information is available regarding the prevalence, time, and cost associated with informal caregiving for elderly cancer patients. MATERIALS AND METHODS To estimate these costs, we used data from the first wave (1993) of the Asset and Health Dynamics (AHEAD) Study, a nationally representative longitudinal survey of people aged 70 or older. Using a multivariable, two-part regression model to control for differences in health and functional status, social support, and sociodemographics, we estimated the probability of receiving informal care, the average weekly number of caregiving hours, and the average annual caregiving cost per case (assuming an average hourly wage of

8.17) for subjects who reported no history of cancer (NC), having a diagnosis of cancer but not receiving treatment for their cancer in the last year (CNT), and having a diagnosis of cancer and receiving treatment in the last year (CT). RESULTS Of the 7,443 subjects surveyed, 6,422 (86%) reported NC, 718 (10%) reported CNT, and 303 (4%) reported CT. Whereas the adjusted probability of informal caregiving for those respondents reporting NC and CNT was 26%, it was 34% for those reporting CT (P <.05). Those subjects reporting CT received an average of 10.0 hours of informal caregiving per week, as compared with 6.9 and 6.8 hours for those who reported NC and CNT, respectively (P <.05). Accordingly, cancer treatment was associated with an incremental increase of 3.1 hours per week, which translates into an additional average yearly cost of

Background In Botswana, an estimated 24% of adults ages 15–49 years are infected with HIV. While alcohol use is strongly associated with HIV infection in Africa, few population-based studies have characterized the association of alcohol use with specific high-risk sexual behaviors. Methods and Findings We conducted a cross-sectional, population-based study of 1,268 adults from five districts in Botswana using a stratified two-stage probability sample design. Multivariate logistic regression was used to assess correlates of heavy alcohol consumption (>14 drinks/week for women, and >21 drinks/week for men) as a dependent variable. We also assessed gender-specific associations between alcohol use as a primary independent variable (categorized as none, moderate, problem and heavy drinking) and several risky sex outcomes including: (a) having unprotected sex with a nonmonogamous partner; (b) having multiple sexual partners; and (c) paying for or selling sex in exchange for money or other resources. Criteria for heavy drinking were met by 31% of men and 17% of women. Adjusted correlates of heavy alcohol use included male gender, intergenerational relationships (age gap ≥10 y), higher education, and living with a sexual partner. Among men, heavy alcohol use was associated with higher odds of all risky sex outcomes examined, including unprotected sex (AOR = 3.48; 95% confidence interval [CI], 1.65 to 7.32), multiple partners (AOR = 3.08; 95% CI, 1.95 to 4.87), and paying for sex (AOR = 3.65; 95% CI, 2.58 to 12.37). Similarly, among women, heavy alcohol consumption was associated with higher odds of unprotected sex (AOR = 3.28; 95% CI, 1.71 to 6.28), multiple partners (AOR = 3.05; 95% CI, 1.83 to 5.07), and selling sex (AOR = 8.50; 95% CI, 3.41 to 21.18). A dose-response relationship was seen between alcohol use and risky sexual behaviors, with moderate drinkers at lower risk than both problem and heavy drinkers. Conclusions Alcohol use is associated with multiple risks for HIV transmission among both men and women. The findings of this study underscore the need to integrate alcohol abuse and HIV prevention efforts in Botswana and elsewhere.

African‐American men have a greater incidence of and mortality from prostate carcinoma compared with white men, and they are less likely to receive definitive therapy (radical prostatectomy or external beam radiation therapy). During the 1990s, the use of brachytherapy increased; however, its influence on racial and ethnic prostate carcinoma treatment trends remains unclear. The objective of this study was to describe treatment trends over the period 1992–1999 for localized/regional prostate carcinoma among white, Hispanic, and African‐American men.

BackgroundAs an increasing number of patients with chronic conditions of childhood survive to adulthood, experts recommend that young adults with chronic conditions transfer from child-focused to adult-focused primary care. Little, however, is known about how comfortable physicians are caring for this population.ObjectivesTo assess the comfort of general internists and general pediatricians in treating young adult patients with chronic illnesses originating in childhood as well as the factors associated with comfort.Participants In a random sample, 1288 of 2434 eligible US general internists and pediatricians completed a mailed survey (response rate = 53%).MethodsWe measured respondents’ comfort level in providing primary care for a patient with sickle cell disease (SCD) or cystic fibrosis (CF). We also measured levels of disease familiarity, training and subspecialty support, as well as individual physician characteristics.ResultsFifteen percent of general internists reported being comfortable as the primary care provider for adults with CF and 32% reported being comfortable providing primary care for adults with SCD, compared with 38% of pediatricians for CF (p < .001) and 35% for SCD (p > 0.05). Less than half of general internists felt that their specialty should take primary care responsibility for adult patients with CF and SCD.ConclusionsA majority of general internists and pediatricians are not comfortable providing primary care for young adults with chronic illnesses of childhood origin, such as CF and SCD. Efforts to increase treatment comfort among providers may help with the transition to adult-focused care for the growing numbers of young adults with complex chronic conditions.

OBJECTIVES Peer review is used to make final judgments about quality of care in many quality assurance activities. To overcome the low reliability of peer review, discussion between several reviewers is often recommended to point out overlooked information or allow for reconsideration of opinions and thus improve reliability. The authors assessed the impact of discussion between 2 reviewers on the reliability of peer review. METHODS A group of 13 board-certified physicians completed a total of 741 structured implicit record reviews of 95 records for patients who experienced severe adverse events related to laboratory abnormalities while in the hospital (hypokalemia, hyperkalemia, renal failure, hyponatremia, and digoxin toxicity). They independently assessed the degree to which each adverse event was caused by medical care and the quality of the care leading up to the adverse event. Working in pairs, they then discussed differences of opinion, clarified factual discrepancies, and rerated the record. The authors compared the reliability of each measure before and after discussion, and between and within pairs of reviewers, using the intraclass correlation coefficient for continuous ratings and the kappa statistic for a dichotomized rating. RESULTS The assessment of whether the laboratory abnormality was iatrogenic had a reliability of 0.46 before discussion and 0.71 after discussion between paired reviewers, indicating considerably improved agreement between the members of a pair. However, across reviewer pairs, the reviewer reliability was 0.36 before discussion and 0.40 after discussion. Similarly, for the rating of overall quality of care, reliability of physician review went from 0.35 before discussion to 0.58 after discussion as assessed by pair. However, across pairs the reliability increased only from 0.14 to 0.17. Even for prediscussion ratings, reliability was substantially higher between 2 members of a pair than across pairs, suggesting that reviewers who work in pairs learn to be more consistent with each other even before discussion, but this consistency also did not improve overall reliability across pairs. CONCLUSIONS When 2 physicians discuss a record that they are reviewing, it substantially improves the agreement between those 2 physicians. However, this improvement is illusory, as discussion does not improve the overall reliability as assessed by examining the reliability between physicians who were part of different discussions. This finding may also have implications with regard to how disagreements are resolved on consensus panels, guideline committees, and reviews of literature quality for meta-analyses.

BACKGROUND Traditionally, thyroid surgery has been an inpatient procedure due to the risk of several well-documented complications. Recent research suggests that for selected patients, outpatient thyroid surgery is safe and feasible, with the additional potential benefit of cost savings. In recognition of these observations, we hypothesized that there would be an increase in U.S. outpatient thyroidectomies with a concurrent decline in inpatient thyroidectomies over time. METHODS Comparative cross-sectional analyses of the National Survey of Ambulatory Surgery (NSAS) and Nationwide Inpatient Sample (NIS) databases from 1996 and 2006 were performed. All cases of thyroid surgery were extracted, as well as data on age, sex, and insurance status. Diagnoses and surgical cases were identified using International Classification of Diseases, Ninth Revision (ICD-9) diagnostic and treatment codes. Hospital charges were acquired from the NIS 1996 and 2006 and NSAS 2006 releases, using imputed data where necessary. After survey weights were applied, patient characteristics, diagnoses, and procedures were compared for inpatient versus outpatient procedures. RESULTS The total number of thyroidectomies increased 39%, from 66,864 to 92,931 cases per year during the study timeframe. Outpatient procedures increased by 61%, while inpatient procedures increased by 30%. The proportion of privately insured inpatients declined slightly from 63.8% to 60.1%, while those covered by Medicare increased from 22.8% to 25.8%. In contrast, the proportion of privately insured outpatients declined sharply from 76.8% to 39.9%, while those covered by Medicare rose from 17.2% to 45.7%. These trends coincided with a small increase in the mean inpatient age from 50.2 to 52.3 years and a larger increase in the mean outpatient age from 50.7 to 58.1 years. Inflation-adjusted per-capita charges for inpatient thyroidectomies more than doubled from
