Risk of subsequent SARS-CoV-2 infection among vaccinated employees with or without hybrid immunity acquired early in the Omicron-predominant era of the COVID-19 pandemic.

BACKGROUND: Hybrid immunity, from COVID-19 vaccination followed by SARS-CoV-2 infection acquired after its Omicron variant began predominating, has provided greater protection than vaccination alone against subsequent infection over 1-3 months of observation. Its longer-term protection is unknown. METHODS: We conducted a retrospective cohort study of COVID-19 case incidence among healthcare personnel (HCP) mandated to be vaccinated and report on COVID-19-associated symptoms, high-risk exposures, or known-positive test results to an employee health hotline. We compared cases with hybrid immunity, defined as incident COVID-19 during the first 6 weeks of Omicron-variant predominance (run-in period), to those with immunity from vaccination alone during the run-in period. Time until COVID-19 infection over 13 subsequent months (observation period) was analyzed by standard survival analysis. RESULTS: Of 5867 employees, 641 (10.9%, 95% confidence interval [CI]: 10.1%-11.8%) acquired hybrid immunity during the run-in period. Of these, 104 (16.2%, 95% CI: 13.5%-19.3%) experienced new SARS-CoV-2 infection during the 13-month observation period, compared to 2177 (41.7%, 95% CI: 40.3%-43.0%) of the 5226 HCP without hybrid immunity. Time until incident infection was shorter among the latter (hazard ratio: 3.09, 95% CI: 2.54-3.78). CONCLUSIONS: In a cohort of vaccinated employees, Omicron-era acquired SARS-CoV-2 hybrid immunity was associated with significantly lower risk of subsequent infection over more than a year of observation-a time period far longer than previously reported and during which three, progressively more resistant, Omicron subvariants became predominant. These findings can inform institutional policy and planning for future COVID-19 additional vaccine dosing requirements for employees, for surveillance programs, and for risk modification efforts.

A Randomized Controlled Trial of a Text Messaging Intervention to Promote Virologic Suppression and Retention in Care in an Urban Safety-Net Human Immunodeficiency Virus Clinic: The Connect4Care Trial.

Background: Text messaging is a promising strategy to support human immunodeficiency virus (HIV) care engagement, but little is known about its efficacy in urban safety-net HIV clinics. Methods: We conducted a randomized controlled trial of a supportive and motivational text messaging intervention, Connect4Care (C4C), among viremic patients who had a history of poor retention or were new to the clinic. Participants were randomized (stratified by new or established HIV diagnosis status) to receive either of the following for 12 months: (1) thrice-weekly intervention messages, plus texted primary care appointment reminders and a monthly text message requesting confirmation of study participation or (2) texted reminders and monthly messages alone. Viral load was assessed at 6 and 12 months. The primary outcome was virologic suppression (<200 copies/mL) at 12 months, estimated via repeated-measures log-binomial regression, adjusted for new-diagnosis status. The secondary outcome was retention in clinic care. Results: Between August 2013 and November 2015, a total of 230 participants were randomized. Virologic suppression at 12 months was similar in intervention and control participants (48.8% vs 45.8%, respectively), yielding a rate ratio of 1.07 (95% confidence interval, .82-1.39). Suppression was higher in those with newly diagnosed infection (78.3% vs 45.3%). There were no intervention effects on the secondary outcome. Exploratory analyses suggested that patients with more responses to study text messages had better outcomes, regardless of arm. Conclusions: The C4C text messaging intervention did not significantly increase virologic suppression or retention in care. Response to text messages may be a useful way for providers to gauge risk for poor HIV outcomes. Clinical Trials Registration: NCT01917994.

Racial/Ethnic Disparities in Arrests for Drug Possession After California Proposition 47, 2011-2016.

OBJECTIVES: To evaluate the effects of California Proposition 47, which reclassified felony drug offenses to misdemeanors in 2014, on racial/ethnic disparities in drug arrests. METHODS: Using data on all drug arrests made in California from 2011 to 2016, we compared racial/ethnic disparities in drug arrests between Whites, Blacks, and Latinos, immediately and 1 year after policy changes, controlling for secular and seasonal trends. RESULTS: In the month following passage, absolute Black-White disparities in monthly felony drug arrests decreased from 81 to 44 per 100 000 and continued to decrease over time. There was an immediate increase of 27% in the relative disparity, however, because a higher proportion of felony offense types among Whites was reclassified. Total drug arrest rates also declined, suggesting drug law enforcement was deprioritized. During the first year after enactment, felony drug arrests fell by an estimated 51 985 among Whites, 15 028 among Blacks, and 50 113 among Latinos. CONCLUSIONS: Reducing criminal penalties for drug possession can reduce racial/ethnic disparities in criminal justice exposure and has implications for improving health inequalities linked to social determinants of health.

The Effect of Patient Navigation on the Likelihood of Engagement in Clinical Care for HIV-Infected Individuals Leaving Jail.

OBJECTIVES: To compare the effectiveness of patient navigation-enhanced case management in supporting engagement in HIV care upon release from jail relative to existing services. METHODS: We randomized 270 HIV-infected individuals to receive navigation-enhanced case management for 12 months or standard case management for 90 days following release from jail between 2010 and 2013. Participants were interviewed at 2, 6, and 12 months after release. We abstracted medical data from jail and city health records. RESULTS: Patient navigation-enhanced case management resulted in greater linkage to care within 30 days of release (odds ratio [OR] = 2.15; 95% confidence interval [CI] = 1.23, 3.75) and consistent retention over 12 months (OR = 1.95; 95% CI = 1.11, 3.46). Receipt of treatment for substance use disorders in jail also resulted in early linkage (OR = 4.06; 95% CI = 1.93, 8.53) and retention (OR = 2.52; 95% CI = 1.21, 5.23). Latinos were less likely to be linked to (OR = 0.35; 95% CI = 0.14, 0.91) or retained in (OR = 0.28; 95% CI = 0.09, 0.82) HIV care. CONCLUSIONS: Patient navigation supports maintaining engagement in care and can mitigate health disparities, and should become the standard of care for HIV-infected individuals leaving jail.

An inpatient treatment and discharge planning protocol for alcohol dependence: efficacy in reducing 30-day readmissions and emergency department visits.

BACKGROUND: Alcohol dependence results in multiple hospital readmissions, but no discharge planning protocol has been studied to improve outcomes. The inpatient setting is a frequently missed opportunity to discuss treatment of alcohol dependence and initiate medication-assisted treatment, which is effective yet rarely utilized. AIM: Our aim was to implement and evaluate a discharge planning protocol for patients admitted with alcohol dependence. SETTING: The study took place at the San Francisco General Hospital (SFGH), a university-affiliated, large urban county hospital. PARTICIPANTS: Learner participants included Internal Medicine residents at the University of California, San Francisco (UCSF) who staff the teaching service at SFGH. Patient participants included inpatients with alcohol dependence admitted to the Internal Medicine teaching service. PROGRAM DESCRIPTION: We developed and implemented a discharge planning protocol for patients admitted with alcohol dependence that included eligibility assessment and initiation of medication-assisted treatment. PROGRAM EVALUATION: Rates of medication-assisted treatment increased from 0% to 64% (p value < 0.001). All-cause 30-day readmission rates to SFGH decreased from 23.4% to 8.2% (p value = 0.042). All-cause emergency department visits to SFGH within 30 days of discharge decreased from 18.8% to 6.1% (p value = 0.056). DISCUSSION: Through implementation of a discharge planning protocol by Internal Medicine residents for patients admitted with alcohol dependence, there was a statistically significant increase in medication-assisted treatment and a statistically significant decrease in both 30-day readmission rates and emergency department visits.

A text messaging intervention to improve retention in care and virologic suppression in a U.S. urban safety-net HIV clinic: study protocol for the Connect4Care (C4C) randomized controlled trial.

BACKGROUND: Few data exist on the use of text messaging as a tool to promote retention in HIV care and virologic suppression at the clinic level in the United States. We describe the protocol for a study designed to investigate whether a text messaging intervention that supports healthy behaviors, encourages consistent engagement with care, and promotes antiretroviral persistence can improve retention in care and virologic suppression among patients in an urban safety-net HIV clinic in San Francisco. METHODS/DESIGN: Connect4Care (C4C) is a single-site, randomized year-long study of text message appointment reminders vs. text message appointment reminders plus thrice-weekly supportive, informational, and motivational text messages. Eligible consenting patients are allocated 1:1 to the two arms within strata defined by HIV diagnosis within the past 12 months (i.e. "newly diagnosed") vs. earlier. Study participants must receive primary care at the San Francisco General Hospital HIV clinic, speak English, possess a cell phone and be willing to send/receive up to 25 text messages per month, a have viral load >200 copies/µL, and be either new to the clinic or have a history of poor retention. The primary efficacy outcome is virologic suppression at 12 months and the key secondary outcome, which will also be examined as a mediator of the primary outcome, is retention in HIV care, as operationalized by kept and missed primary care visits. Process outcomes include text message response rate and percent of time in study without cell phone service. Generalized estimating equation log-binomial models will be used for intent to treat, per protocol, and mediation analyses. An assessment of the cost and cost-effectiveness of the intervention is planned along with a qualitative evaluation of the intervention. DISCUSSION: Findings from this study will provide valuable information about the use of behavioral-theory based text messaging to promote retention in HIV care and virologic suppression, further elucidate the challenges of using texting technology with marginalized urban populations, and help guide the development of new mobile health strategies to improve HIV care cascade outcomes. TRIAL REGISTRATION: NCT01917994.

Effect of Methadone Dose on Maintenance Treatment and Health Consequences Among Heroin Addicts in South China.

A retrospective cross-sectional study was conducted with a convenience sample of 197 adults receiving methadone maintenance treatment in Kunming city, South China, in 2010. The aim of the study was to determine the association of methadone maintenance dose on a variety of treatment outcomes. Treatment modalities, the adverse reactions to methadone treatment, the physical and mental outcomes of the treatment, and risk behavior changes were assessed. Multilevel negative and logistic binomial regression analyses were carried out, which demonstrated that methadone maintenance dose in this sample was not associated with improved treatment adherence or with quality of life. We concluded that dose had a small, if negligible, influence on the changes in adverse effects of methadone. Further research in dose differences between the genders should be conducted.

Confined to ignorance: the absence of prisoner information from nationally representative health data sets.

BACKGROUND: Incarceration is associated with poor health and high costs. Given the dramatic growth in the criminal justice system's population and associated expenses, inclusion of questions related to incarceration in national health data sets could provide essential data to researchers, clinicians and policy-makers. OBJECTIVE: To evaluate a representative sample of publically available national health data sets for their ability to be used to study the health of currently or formerly incarcerated persons and to identify opportunities to improve criminal justice questions in health data sets. DESIGN & APPROACH: We reviewed the 36 data sets from the Society of General Internal Medicine Dataset Compendium related to individual health. Through content analysis using incarceration-related keywords, we identified data sets that could be used to study currently or formerly incarcerated persons, and we identified opportunities to improve the availability of relevant data. KEY RESULTS: While 12 (33%) data sets returned keyword matches, none could be used to study incarcerated persons. Three (8%) could be used to study the health of formerly incarcerated individuals, but only one data set included multiple questions such as length of incarceration and age at incarceration. Missed opportunities included: (1) data sets that included current prisoners but did not record their status (10, 28%); (2) data sets that asked questions related to incarceration but did not specifically record a subject's status as formerly incarcerated (8, 22%); and (3) longitudinal studies that dropped and/or failed to record persons who became incarcerated during the study (8, 22%). CONCLUSIONS: Few health data sets can be used to evaluate the association between incarceration and health. Three types of changes to existing national health data sets could substantially expand the available data, including: recording incarceration status for study participants who are incarcerated; recording subjects' history of incarceration when this data is already being collected; and expanding incarceration-related questions in studies that already record incarceration history.

HIV infection as a predictor of methadone maintenance outcomes in Chinese injection drug users.

This paper's design is descriptive and correlational based on retrospective self-report survey data collected in Kunming city, China. The study investigated the difference between a group of Chinese HIV positive (N=36) and negative (N=131) opioid dependent adults maintained on methadone treatment. Comparisons were based on their quality of life (QOL), methadone treatment adherence, adverse symptom occurrence related to methadone treatment, and HIV-related behavior changes. No significant differences were found between the two groups in age, methadone maintenance dose, methadone adherence, sex desire, and drug craving level. Participants who were HIV positive reported significantly lower scores on physical health and total health-related qualify of life. They also reported greater engagement in injection related risk behavior before methadone treatment than those who tested HIV negative. For both groups, sexual and injection risk behavior significantly decreased following initiation of methadone treatment. A regression model revealed that those infected with HIV, associated significantly with higher likelihood of reporting constipation and lack of appetite, and higher frequency of reporting abdominal pain and nausea than HIV negative patients. The primary implication of these findings is that HIV positive persons in methadone treatment may require more focused services to meet their special HIV care and substance treatment needs.

Directly observed versus self-administered antiretroviral therapies: preference of HIV-positive jailed inmates in San Francisco.

Directly observed therapy (DOT) of antiretroviral (ARV) medications has beneficial effects on HIV treatment for incarcerated inmates but has been associated with limited continuation after release and inadvertent disclosure of HIV status. Guided self-administered therapy (g-SAT) may be a preferred method of ARV delivery and may encourage medication-taking behavior. We surveyed the preference of 102 HIV-positive jailed inmates at the San Francisco City and County Jails regarding receiving ARVs via DOT versus g-SAT while incarcerated. Participants overwhelmingly preferred g-SAT over DOT.

Basic subsistence needs and overall health among human immunodeficiency virus-infected homeless and unstably housed women.

Some gender differences in the progression of human immunodeficiency virus (HIV) infection have been attributed to delayed treatment among women and the social context of poverty. Recent economic difficulties have led to multiple service cuts, highlighting the need to identify factors with the most influence on health in order to prioritize scarce resources. The aim of this study was to empirically rank factors that longitudinally impact the health status of HIV-infected homeless and unstably housed women. Study participants were recruited between 2002 and 2008 from community-based venues in San Francisco, California, and followed over time; marginal structural models and targeted variable importance were used to rank factors by their influence. In adjusted analysis, the factor with the strongest effect on overall mental health was unmet subsistence needs (i.e., food, hygiene, and shelter needs), followed by poor adherence to antiretroviral therapy, not having a close friend, and the use of crack cocaine. Factors with the strongest effects on physical health and gynecologic symptoms followed similar patterns. Within this population, an inability to meet basic subsistence needs has at least as much of an effect on overall health as adherence to antiretroviral therapy, suggesting that advances in HIV medicine will not fully benefit indigent women until their subsistence needs are met.

Sensitivity and Specificity of the National Death Index for Multiple Causes of Death in People With HIV.

OBJECTIVES: Inaccuracies in cause-of-death information in death certificates can reduce the validity of national death statistics and result in poor targeting of resources to reduce morbidity and mortality in people with HIV. Our objective was to measure the sensitivity, specificity, and agreement between multiple causes of deaths from death certificates obtained from the National Death Index (NDI) and causes determined by expert physician review. METHODS: Physician specialists determined the cause of death using information collected from the medical records of 50 randomly selected HIV-infected people who died in San Francisco from July 1, 2016, through May 31, 2017. Using expert review as the gold standard, we measured sensitivity, specificity, and agreement. RESULTS: The NDI had a sensitivity of 53.9% and a specificity of 66.7% for HIV deaths. The NDI had a moderate sensitivity for non-AIDS-related infectious diseases and non-AIDS-related cancers (70.6% and 75.0%, respectively) and high specificity for these causes (100.0% and 94.7%, respectively). The NDI had low sensitivity and high specificity for substance abuse (27.3% and 100.0%, respectively), heart disease (58.3% and 86.8%, respectively), hepatitis B/C (33.3% and 97.7%, respectively), and mental illness (50.0% and 97.8%, respectively). The measure of agreement between expert review and the NDI was lowest for HIV (κ = 0.20); moderate for heart disease (κ = 0.45) and hepatitis B/C (κ = 0.40); high for non-AIDS-related infectious diseases (κ = 0.76) and non-AIDS-related cancers (κ = 0.72); and low for all other causes of death (κ < 0.35). CONCLUSIONS: Our findings support education and training of health care providers to improve the accuracy of cause-of-death information on death certificates.

Emergency contraception for newly arrested women: evidence for an unrecognized public health opportunity.

Incarceration affords an opportunity to provide health care to populations with limited access to care. Women in this population are at high risk for experiencing unintended pregnancies. It is not known what proportion of these women engage in unprotected intercourse in the days prior to incarceration and therefore may benefit from being offered emergency contraception upon their arrest to decrease their risk of unintended pregnancies. We sought to describe the proportion and characteristics of newly arrested women who are eligible for and interested in taking emergency contraception by conducting a cross-sectional study in an urban county jail booking facility. A 63-item survey was administered to women ages 18-44 within 24 h of being arrested in San Francisco. Eighty-four (29%) women were eligible for emergency contraception. Of these, 48% indicated a willingness to take emergency contraception if offered. Half of the women eligible for emergency contraception expressed ambivalent attitudes about pregnancy. Women who had taken emergency contraception in the past were more likely to say they would accept it (45%) than women who had never used it (25%, p = .05). The strongest predictor of willingness to take emergency contraception was not having a misperception about its safety, efficacy, or mechanism of action (RR = 1.9, 95% CI 1.2-3.0). Seventy-one percent of all women indicated that they would accept an advance supply of emergency contraception upon release from jail. Emergency contraception counseling and provision should be offered to newly arrested women as a key reproductive and public health intervention for a traditionally marginalized, high-risk population.

Gender-specific correlates of incarceration among marginally housed individuals in San Francisco.

OBJECTIVES: We assessed how different patterns of housing instability affect incarceration and whether correlates of incarceration are gender specific. METHODS: We used multivariate logistic regression to assess associations between patterns of housing instability and recent jail stays among a reproducible sample of 1175 marginally housed adults in San Francisco, California. RESULTS: Over the previous year, 71% of men and 21% of women in the sample reported jail stays. Among women, long-term single-room occupancy hotel stays ( > 90 days) were protective for incarceration. Stays in the street were associated with incarceration among both genders, but among men, short-term (i.e.,

Profile of adults seeking voluntary HIV testing and counseling in rural Central India: results from a hospital-based study.

Rural India has an undetected load of HIV-positive individuals. Few rural adults present for HIV testing and counseling due to stigma, discrimination, and fear of social ostracization. In this rural hospital clinic-based study, we document profiles of rural adults seeking voluntary testing and counseling, and analyze correlates of HIV seropositivity. This cross-sectional study was conducted in 450 participants presenting to the outpatient clinics of Mahatma Gandhi Institute of Medical Sciences, Sevagram, Central India. After informed consent, pre- and post-test counseling, HIV testing, and face-to-face interviews were conducted. Data were collected using a structured questionnaire. The median age of the 450 study participants was 34 years (range 18-88 years); the majority (74%) was married. The overall proportion of HIV seropositivity was 32% [95% CI 28%, 37%]. The proportions of HIV seropositivity in married women, married men, and single men were 41%, 37%, 18%, respectively. No single woman was found seropositive in the study. Very few married women were aware of their husbands' HIV status. In a multivariate analysis, correlates of HIV seropositivity in men were: age 30-39 years, being married, having sex with multiple partners, use of alcohol before sex, and testing positive for HIV in the past. In married women, the only predictor of seropositivity was being married. Although limited by the non-random nature of the sampling method, this pilot study is unique in that it is the first from this rural region of Central India. It provides baseline data on marginalized, largely unstudied populations that may aid in designing probabilistic community-based surveys in this neglected population.

Effects of a voter initiative on disparities in punishment severity for drug offenses across California counties.

BACKGROUND: The jurisdiction where an offense is prosecuted significantly affects the severity of punishment for drug possession, creating geographic disparities in exposure to a social determinant of health. In California, felony conviction rates after drug possession arrests have historically varied enormously between counties. California Proposition 47 (Prop-47), passed in 2014, reduced drug possession offenses previously classified as felonies or wobblers (offenses for which prosecutors have discretion to file felony or misdemeanor charges) to misdemeanors. This study examines whether geographic variation in felony convictions after drug possession arrests was reduced, and whether effects were offset by changes in felony convictions for other offenses not addressed by Prop-47. METHODS: Arrests made after the implementation of Prop-47 were propensity score matched to similar arrests prior to Prop-47 to account for compositional changes in arrests. This approach compares the outcomes of individuals likely to be arrested with or without the reclassification of drug offenses. We used mixed models to estimate the change in county variance in the probability of felony conviction. RESULTS: The probability of a felony conviction among those arrested for Prop-47 drug offenses declined by 14 percentage points (95% CI: -0.16, -0.12), from 0.20 (95% CI: 0.18, 0.23) to 0.06 (95% CI: 0.06, 0.07). Counties with higher felony conviction probabilities pre-Prop-47 declined most, reducing cross-county variance. For those arrested for drug offenses unaffected by Prop-47, the probability of felony conviction declined by 7 percentage points (95% CI: -0.08, -0.05), from 0.34 (95% CI: 0.31, 0.37) to 0.27 (0.25, 0.29). Declines in both groups were driven by fewer felony convictions for Prop-47 drug offenses, with no increases in felony convictions for concurrent offenses. CONCLUSION: Reducing offense classifications for drug possession reduced previously large differences in the probability of felony convictions for people arrested for drug offenses in different counties.

Impact of round-the-clock, rapid oral fluid HIV testing of women in labor in rural India.

BACKGROUND: Testing pregnant women for HIV at the time of labor and delivery is the last opportunity for prevention of mother-to-child HIV transmission (PMTCT) measures, particularly in settings where women do not receive adequate antenatal care. However, HIV testing and counseling of pregnant women in labor is a challenge, especially in resource-constrained settings. In India, many rural women present for delivery without any prior antenatal care. Those who do get antenatal care are not always tested for HIV, because of deficiencies in the provision of HIV testing and counseling services. In this context, we investigated the impact of introducing round-the-clock, rapid, point-of-care HIV testing and counseling in a busy labor ward at a tertiary care hospital in rural India. METHODS AND FINDINGS: After they provided written informed consent, women admitted to the labor ward of a rural teaching hospital in India were offered two rapid tests on oral fluid and finger-stick specimens (OraQuick Rapid HIV-1/HIV-2 tests, OraSure Technologies). Simultaneously, venous blood was drawn for conventional HIV ELISA testing. Western blot tests were performed for confirmatory testing if women were positive by both rapid tests and dual ELISA, or where test results were discordant. Round-the-clock (24 h, 7 d/wk) abbreviated prepartum and extended postpartum counseling sessions were offered as part of the testing strategy. HIV-positive women were administered PMTCT interventions. Of 1,252 eligible women (age range 18 y to 38 y) approached for consent over a 9 mo period in 2006, 1,222 (98%) accepted HIV testing in the labor ward. Of these, 1,003 (82%) women presented with either no reports or incomplete reports of prior HIV testing results at the time of admission to the labor ward. Of 1,222 women, 15 were diagnosed as HIV-positive (on the basis of two rapid tests, dual ELISA and Western blot), yielding a seroprevalence of 1.23% (95% confidence interval [CI] 0.61%-1.8%). Of the 15 HIV test-positive women, four (27%) had presented with reported HIV status, and 11 (73%) new cases of HIV infection were detected due to rapid testing in the labor room. Thus, 11 HIV-positive women received PMTCT interventions on account of round-the-clock rapid HIV testing and counseling in the labor room. While both OraQuick tests (oral and finger-stick) were 100% specific, one false-negative result was documented (with both oral fluid and finger-stick specimens). Of the 15 HIV-infected women who delivered, 13 infants were HIV seronegative at birth and at 1 and 4 mo after delivery; two HIV-positive infants died within a month of delivery. CONCLUSIONS: In a busy rural labor ward setting in India, we demonstrated that it is feasible to introduce a program of round-the-clock rapid HIV testing, including prepartum and extended postpartum counseling sessions. Our data suggest that the availability of round-the-clock rapid HIV testing resulted in successful documentation of HIV serostatus in a large proportion (82%) of rural women who were unaware of their HIV status when admitted to the labor room. In addition, 11 (73%) of a total of 15 HIV-positive women received PMTCT interventions because of round-the-clock rapid testing in the labor ward. These findings are relevant for PMTCT programs in developing countries.

Discharge planning and continuity of health care: findings from the San Francisco County Jail.

Continuity of health care among the formerly incarcerated is an emerging public health challenge. We used data from the San Francisco County Jail to determine whether discharge planning improves access to care on release. Inmates who were HIV positive and received discharge planning were 6 times more likely to have a regular source of care in the community compared with inmates with other chronic medical conditions, and they were as likely to have a regular source of care compared with the general San Francisco population.

Voucher reinforcement improves medication adherence in HIV-positive methadone patients: a randomized trial.

This clinical trial evaluated a contingency management intervention designed to improve medication adherence among HIV-positive methadone maintenance patients. After a 4-week baseline observation phase, eligible participants (N=66) were randomly assigned to: (a) medication coaching sessions every other week to assist with adherence strategies (comparison group) or (b) medication coaching plus voucher reinforcement for opening electronic medication caps on time (voucher group). Baseline adherence (percent doses taken/percent total possible doses) was 51% using electronic measurement, 75% using self-report and 75% using pill count. The intervention was provided for 12 weeks, with a 4-week follow-up. The primary outcome results of the clinical trial indicated effectiveness during the intervention, with significant mean adherence differences between voucher and comparison groups using electronic measurement (78% versus 56%), pill count (86% versus 75%), and self-report (87% versus 69%). Differences between groups faded after vouchers were discontinued. Contingency management shows promise as a strategy to promote antiretroviral medication adherence in this population.

The catch 22 of condoms in US correctional facilities.

BACKGROUND: Despite the high prevalence of sexually transmitted infections (STIs) and HIV infection in US correctional settings, most jails and prisons in the United States prevent inmates from using condoms to prevent STIs/HIV. DISCUSSION: This article makes the following arguments to justify a scalable and feasible next step in the prevention of HIV/STIs among inmates: condoms are a basic and essential part of HIV/STI prevention, HIV/STI transmission occurs in the context of corrections, and several model programs show the feasibility of condom distribution in prisons. A lower end estimate for HIV incidence among incarcerated applied to 2,000,000 new inmates annually results in thousands of new HIV infections acquired each year in corrections that could be prevented with condoms in corrections facilities. Programs from parts of the United States, Canada, and much of Europe show how programs distributing condoms in correctional facilities can be safe and effective. SUMMARY: Public health and corrections officials must work together to ensure that condoms and broader sexual disease prevention programs are integrated into US jail and prison health systems.
