South African women experience high levels of alcohol use and HIV infection during the perinatal period. Oral pre-exposure prophylaxis (PrEP) is highly effective at reducing HIV risk. We examined associations between alcohol use and PrEP use during pregnancy and postpartum.PrEP-PP is a prospective observational cohort of 1200 HIV-negative pregnant women enrolled at first antenatal care visit and followed through 12 months postpartum in Cape Town, South Africa. The analytic sample comprised pregnant women who initiated PrEP at baseline and were not censored from study follow-up prior to 3 month follow-up. We examined associations between any or hazardous alcohol use (AUDIT-C score ≥3) in the year prior to pregnancy and PrEP continuation and adherence during pregnancy (self-report of missing2 doses in past 7 days, and biomarker-confirmed with tenofovir diphosphate in dried blood spots).Of 943 women on PrEP (median age 26 years), 50% reported alcohol use prior to pregnancy and 33% reported hazardous use. At 3 month follow-up, 58% of women were still using PrEP; 41% reported recent adherence and 23% were biomarker-confirmed adherent. In multivariable models, hazardous alcohol use was associated with increased odds of continuing PrEP (aOR=1.54, 95% CI: 1.16-2.06), self-reported PrEP adherence (aOR=1.41, 95% CI: 1.07-1.87), and biomarker- confirmed PrEP adherence (aOR=1.35 95% CI: 0.98, 1.87). Associations were similar in models of any alcohol use and PrEP continuation/adherence.Pregnant and postpartum women who reported recent alcohol use had increased odds of continuing to take PrEP, indicating that higher risk women may continue on oral PrEP.

Sexually transmitted infections (STIs), STI reinfection, Human Immunodeficiency Virus (HIV) acquisition and changes in behaviors following an STI were examined in a cohort of men who have sex with men (MSM) in Los Angeles, CA.Data from a longitudinal study of MSM enrolled from 2014 with at least one follow-up visit through March 2020 were analyzed (n = 447; 1,854 visits). Study visits every 6 months included self-interviews for sexual behaviors, substance use, and specimen collection for chlamydia, gonorrhea, syphilis, and HIV testing. Changes in behaviors were assessed using McNemar's test and participants not diagnosed with an STI served as controls for a difference-in-differences (DiD) analysis of changes over time.Cumulative incidence of an STI was 55% (248/447). At 24-months post STI diagnosis methamphetamine use declined from 50% to 35% (p.01), and median number of sex partners declined from 5 (IQR: 2-11) to 2 (IQR: 1-6)(p.01). Among participants at risk for HIV and diagnosed with an STI (n = 102), PrEP use was 35% and HIV-seroconversion was 6%. Based on DiD analyses, participants diagnosed with an STI had higher levels of substance and higher number of sex partners when compared to those with no STIs, however, declines in these behaviors were comparable to participants not diagnosed with an STI (pDID0.05).Despite behavior modifications following an STI diagnosis, STI/HIV incidence was high, suggesting that MSM with STIs occupy sexual networks where reductions in sexual and substance using behaviors do not protect them from ongoing exposure to STIs and HIV.

In settings with a high burden of HIV, pregnant women often experience a cluster of risk factors, including alcohol use and intimate partner violence (IPV). These interrelated risks are poorly understood among pregnant women at risk of HIV in sub-Saharan Africa. We aim to determine cross-sectional associations between pregnant women's alcohol use and victimization due to IPV in the HIV-Unexposed-Uninfected Mother-Infant Cohort Study in Cape Town, South Africa. Women who tested HIV-negative at first antenatal care (ANC) visit were followed to delivery. Trained interviewers collected demographic and psychosocial information, including recent alcohol use and experiences of IPV victimization. We assess the prevalence of alcohol use and associations with IPV using multivariable logistic regression. In 406 HIV-uninfected pregnant women (mean age = 28 years; mean gestational age = 21 weeks), 41 (10%) reported alcohol consumption in the past 12 months; 30/41 (73%) of these at hazardous levels. Any and hazardous alcohol use were associated with greater odds of reporting past year IPV (adjusted odds ratio [aOR] for hazardous use: 3.24, 95% CI = 1.11, 7.56; aOR for any alcohol use: 2.97, 95% CI = 1.19, 7.45). These data suggest the occurrence of overlapping HIV risk factors among pregnant women and may help design improved health interventions in this population.

The syndemic relationship between harmful alcohol use, intimate partner violence (IPV), and HIV is well established across international settings. Less is known about how these health issues are perceived by women living with HIV (WLWH), who are disproportionately affected by these intertwined epidemics. A qualitative study was undertaken with 20 WLWH in Rakai, Uganda, to assess their perceptions of how these issues have affected their lives and their communities and to assess the acceptability of integrating a screening and brief intervention for alcohol use and IPV into HIV posttest counseling. Recommendations for intervention programming arising from the results are discussed.

Mental health disorders account for a heavy disease burden in Uganda. In order to provide culturally appropriate mental health prevention and treatment approaches, it is necessary to understand how mental health is conceptualized in the population. Three focus group discussions (FGDs) and 31 in-depth interviews (IDIs) were conducted with men and women aged 14 to 62 years residing in rural, urban, and semi-urban low-income communities in central and western Uganda to explore perceptions and knowledge of mental health. Interpretive thematic analysis was undertaken; results were organized through the lens of the mental health literacy framework. Environmental and societal stressors were identified as primary underlying causes of poor mental health. While participants recognized symptoms of poor mental health, gaps in mental health literacy also emerged. Mental health resources are needed in this setting and additional qualitative work assessing knowledge and attitudes toward mental health care seeking behavior can inform the development of acceptable integrated services.

BACKGROUND: In Uganda, depression is a major public health issue because of its direct disease burden and as a risk factor and co-morbidity for other pervasive health issues. Psychometric assessment of translated depression measures is critical to public health planning to ensure proper screening, surveillance, and treatment of depression and related outcomes. We examined aspects of the validity and reliability of the Patient Health Questionnaire-9 (PHQ-9) translated into Luganda and Runyoro in a large population-based cohort of Ugandan adolescents and adults. METHODS: Data from the ongoing open cohort AMBSO Population Health Surveillance study were analyzed from the Wakiso and Hoima districts in Uganda. Descriptive statistics were calculated for the overall sample and stratified by translated language. Construct validity was assessed for each translated scale using confirmatory factor analysis for ordinal data. The internal consistency of each translated scale was assessed using Cronbach’s alpha, McDonald’s omega total and omega hierarchical. RESULTS: Compared to the Runyoro-speaking subsample from Hoima (n=2297), participants in the Luganda-speaking subsample from Wakiso (n=672) were older (27 vs 21 years, p < 0.01) and a greater proportion were female (62% vs. 55%, p < 0.01). The Luganda-translated PHQ-9 had a sample mean of 3.46 (SD=3.26), supported a single-factor structure (RMSEA=0.05, CFI=0.96, TLI=0.94), and demonstrated satisfactory internal consistency (Cronbach’s alpha=0.73, McDonald’s omega total=0.76, McDonald’s omega hierarchical=0.53). The Runyoro-translated PHQ-9 had a comparable sample mean of 3.58 (SD=3.00), also supported a one-factor structure (RMSEA=0.08, CFI=0.92, TLI=0.90), and demonstrated satisfactory internal consistency (Cronbach’s alpha=0.72, McDonald’s omega total=0.76, McDonald’s omega hierarchical=0.57). CONCLUSIONS: Our preliminary findings indicate that the Luganda and Runyoro translations of the PHQ-9 had satisfactory construct validity and internal consistency in our sample of Ugandan adolescents and adults. Future studies should expand on this promising work by assessing additional psychometric characteristics of these translated measures in other communities in Uganda.

This study examines baseline associations between alcohol use and HIV sexual risk among a cohort of HIV-uninfected pregnant women (n = 1201) residing in a high HIV burdened community in Cape Town,South Africa. Alcohol use was measured using a modified version of the Alcohol Use Disorder Identification Test (AUDIT). HIV sexual risk was measured through a composite variable of four risk factors: diagnosis with a STI, self-report of > 1 recent sex partners, partner HIV serostatus (unknown or HIV+) and condomless sex at last sex. Any past year alcohol use prior to pregnancy was reported by half of participants (50%); 6.0% reported alcohol use during pregnancy. Alcohol use prior to pregnancy was associated with increased odds of being at high risk of HIV (aOR = 1.33, 95% CI 1.05-1.68, for 2 risks and aOR = 1.47, 95% CI 0.95-2.27 for 3 risks). In addition to reducing alcohol use, several other strategies to address HIV sexual risk were identified. Evidence-based interventions to address alcohol use and other HIV sexual risk behaviors during pregnancy in South Africa are desperately needed. Qualitative work exploring individual and community level drivers of alcohol use among pregnant and breastfeeding women in this setting could support development of a culturally tailored intervention to address these issues in this population.

Background Alcohol use is common among persons living with HIV (PWH) in Uganda and associated with poor HIV care outcomes; findings regarding the relationship between alcohol use and viral suppression (VS) have been inconclusive. Methods Data from two rounds (2017–2020) of the Rakai Community Cohort Study, an open population-based cohort study in the Rakai region, Uganda, were analyzed. Two alcohol exposures were explored: past year alcohol use and alcohol-related consequences. Multivariable models (GEE) were used to estimate associations between alcohol exposures and VS for the overall sample and stratified by sex, adjusting for repeated measurement. Causal mediation by ART use was explored. Results Over half (55 %) of participants (n = 3823 PWH) reported alcohol use at baseline; 37.8 % of those reporting alcohol use reported alcohol-related consequences. ART use and VS at baseline significantly differed by alcohol use with person reporting alcohol use being less likely to be on ART or VS. Alcohol use was significantly associated with decreased odds of VS among women but not men (adj. OR 0.72 95 % CI 0.58−0.89, p = 0.0031). However, among males who use alcohol, experiencing alcohol-related consequences was significantly associated with decreased odds of VS (adj. OR 0.69 95 % CI 0.54−0.88, p = 0.0034). The relationships between both alcohol exposures and VS were not significant in models restricted to persons on ART. Conclusions We provide sex-stratified estimates of associations between two alcohol measures and VS in the context of current HIV treatment guidelines. This study confirms that alcohol use is adversely associated with VS but ART use mediates this pathway, suggesting that initiation and retention on ART are critical steps to addressing alcohol-related disparities in VS.

Introduction Uganda confirmed its first COVID-19 case in March 2020, leading to country-wide closures and a stay-at-home order. Infectious disease pandemics can overwhelm adaptive coping capacity (e.g., general self-efficacy and resilience) and increase the risk for mental distress. For individuals experiencing intimate partner violence (IPV) and cohabitating with a perpetrator, stay-at-home orders can also increase risk of violence, which can further exacerbate mental distress. The present study explores women’s perceived self-efficacy and resilient coping, mental health outcomes (depression and COVID-19 related anxiety), hazardous alcohol use and IPV in the context of Uganda’s national 2020 lockdown. Methods A phone-based survey was undertaken from June-August of 2020 in Wakiso District, Uganda. The study sample consisted of Africa Medical and Behavioral Sciences Organization (AMBSO) Population Health Surveillance (APHS) study participants who agreed to be contacted for future research. The analytic sample was restricted to women aged 13–80 years. Bivariate analysis and multivariable models explored associations between experiences of IPV and measures of adaptive coping, mental health and alcohol use. Results A total of 556 women aged 13–79 years (mean age of 33.4 years) participated. Over half (55%) were currently married. The majority (60%) reported a decrease in alcohol use during the lockdown. Nearly half of the sample were experiencing physical or verbal IPV and reported an increase in violence during the lockdown. In adjusted analysis, alcohol use was associated with four times greater odds of recent physical IPV (aOR 4.06, 95% CI = 1.65–10.02, p = 0.0024), while participants had lower odds of experiencing any form of IPV as general self-efficacy increased (aOR 0.95, 95% CI = 0.91–0.99, p = 0.0308). Conclusion Lockdown measures in Uganda may have mitigated increased alcohol consumption. IPV was exacerbated during lockdown; more than 2 in 5 IPV victims experienced increased physical or verbal violence. Development of programming and policies aimed at mitigating women’s risk of IPV during future lockdowns are needed.

Transactional sex (TS) is prevalent in sub-Saharan Africa. Women's engagement in TS is linked with HIV infection; little is known about the relationship between TS, intimate partner violence (IPV) and alcohol use-established HIV risk behaviors. Using modified Poisson regression, we assessed associations between TS and physical, verbal and sexual IPV among 8248 women (15-49 years) who participated in the Rakai Community Cohort Study across forty communities in Uganda. An interaction term assessed moderation between alcohol use and TS and no significant interaction effects were found. In adjusted analysis, alcohol use and TS were significantly associated with all forms of IPV. In stratified analysis, TS was only associated with IPV in agrarian communities; alcohol use was not associated with physical IPV in trade communities or sexual IPV in trade and fishing communities. Identifying differences in IPV risk factors by community type is critical for the development of tailored interventions.El sexo transaccional (ST) es frecuente en África subsahariana. La participación de las mujeres en el ST está relacionada con la infección por VIH; Se sabe poco sobre la relación entre el ST, la violencia de pareja íntima (VPI) y el consumo de alcohol: conductas de riesgo establecidas para el VIH. Utilizando la regresión de Poisson modificada, evaluamos las asociaciones entre el ST y la VPI física, verbal y sexual entre 8,248 mujeres (15-49 años) que participaron en el Estudio de cohorte de la comunidad Rakai en cuarenta comunidades de Uganda. Un término de interacción evaluó la moderación entre el consumo de alcohol y el ST y no se encontraron efectos de interacción significativos. En el análisis ajustado, el consumo de alcohol y el ST se asociaron significativamente con todas las formas de VPI. En el análisis estratificado, el ST solo se asoció con la VPI en las comunidades agrarias; El consumo de alcohol no se asoció con la VPI física en las comunidades comerciales ni con la VPI sexual en las comunidades comerciales y pesqueras. Identificar las diferencias en los factores de riesgo de la violencia de género por tipo de comunidad es fundamental para el desarrollo de intervenciones personalizadas.

Objective Assess the effect of non-pharmacological alcohol interventions on reducing heavy episodic drinking (HED) outcomes in sub-Saharan Africa. Methods A systematic review of the available literature through August 19, 2020 was conducted. Randomized and non-randomized controlled trials testing non-pharmacological interventions on alcohol consumption in sub-Saharan Africa were eligible for inclusion. Eligible outcomes included measures of HED/binge drinking, and measures indicative of this pattern of drinking, such as high blood alcohol concentration or frequency of intoxication. Three authors extracted and reconciled relevant data and assessed risk of bias. The review protocol is available on PROSPERO (registration number: CRD42019094509). The Cochrane Handbook recommendations for the review of interventions and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines guided all methodology. Results Thirteen intervention trials were identified that met our inclusion criteria and measured change in HED. Studies were judged of moderate quality. A beneficial effect of non-pharmacological interventions on HED was reported in six studies, three of which were deemed clinically significant by the review authors; no statistically significant effects were identified in the other seven studies. Interventions achieving statistical and/or clinical significance had an intervention dose of two hours or greater, used an array of psychosocial approaches, including Motivational Interviewing integrated in Brief Intervention, cognitive behavioral therapy and integrated risk reduction interventions, and were delivered both individually and in groups. Conclusions Evidence for the effectiveness of non-pharmacological interventions to reduce HED in sub-Saharan African settings was limited, demonstrating the need for more research. To strengthen the literature, future research should employ more rigorous study designs, improve consistency of HED measurement, test interventions developed specifically to address HED, and explore structural approaches to HED reduction.

Surgical resection of advanced head and neck squamous cell carcinoma (HNSCC) poses a unique clinical challenge due to nearby vital structures necessary for speech, swallowing, and breathing. Aggressive surgical resection severely impairs functioning and quality of life. Despite considerable advancements in the treatment of HNSCC, long-term survival has continued to be poor in the past 30 years. The standard of care for most HNSCC remains surgery followed by adjuvant radiation and/or chemotherapy. To improve patient survival and preserve critical functions that directly impact quality of life, innovative treatment modality and delivery mechanisms have been explored, with promising results. Several novel drug delivery modalities offer a new potential for patients with advanced HNSCC. These thoughtfully engineered materials can exhibit release of chemotherapeutics at variable kinetics, provide enhanced imaging techniques allowing for minimization of radiation exposure, and optimize immunomodulatory signals to combat the tumor microenvironment.

Logistic regression models assessed associations between past year alcohol use and sociodemographic characteristics, other drug use and HIV status, controlling for age, religion, education, occupation, marital status, and household socioeconomic status.ResultsPast year alcohol prevalence was 45%. Odds of drinking were significantly higher in men (versus women) and fishing communities (versus agrarian areas). Odds of drinking increased with age, previous (versus current) marriage and past year drug use. By occupation, highest odds of drinking were among fishermen and (in women) bar/restaurant workers. Alcohol-related consequences were more commonly reported by male (vs. females) drinkers, among whom up to 35% reported alcohol dependence symptoms (e.g., unsteady gait). HIV status was strongly associated with alcohol use in unadjusted but not adjusted models.ConclusionsAlcohol use differed by gender, community type and occupation. Being male, living in a fishing community and working as a fisherman or restaurant/bar worker (among women) were associated with higher odds of drinking. Alcohol reduction programs should be implemented in Uganda's fishing communities and among people working in high risk occupations (e.g., fishermen and restaurant/bar workers).

BACKGROUND Harmful alcohol use is a leading cause of morbidity and mortality in sub-Saharan Africa (sSA); however, the effects of non-pharmacological alcohol interventions in this region are unknown. DESIGN A systematic review and meta-analysis of the available literature through 14 March 2019 was undertaken. Two authors extracted and reconciled relevant data and assessed risk of bias. Meta-analyses were conducted. The review protocol is registered on International Prospective Register of Systematic Reviews (PROSPERO) (CRD42019094509). SETTING Studies conducted in sSA were eligible for inclusion. PARTICIPANTS Individuals participating in interventions aimed at reducing alcohol use. INTERVENTIONS Randomized and non-randomized controlled trials testing non-pharmacological interventions (psychosocial and structural) on alcohol consumption in sSA. MEASUREMENTS Eligible outcomes included the Alcohol Use Disorders Identification Test (AUDIT) scores; alcohol abstinence; measures of drinking quantity and frequency; and biomarkers of alcohol consumption. FINDINGS Nineteen intervention trials (18 reports) testing psychosocial interventions (no structural interventions included), judged of moderate quality, were included in meta-analyses. A beneficial effect was identified for psychosocial interventions on alcohol abstinence at 3-6 months [odds ratio (OR) = 2.05, 95% confidence interval (CI) = 1.20-3.48, k = 5, n = 2312, I2 = 79%] and 12-60 months (OR = 1.91, 95% CI = 1.40-2.61, k = 6, n = 2737, I2 = 63%) follow-up. There were no statistically significant effects found for AUDIT score [2-3 months: mean differences (MD) = -1.13, 95% CI = -2.60 to 0.34, k = 6, n = 992, I2 = 85%; 6 months: MD = -0.83, 95% CI = -1.92 to 0.26, k = 6, n = 1081, I2 = 69%; 12 months: MD = -0.15, 95% CI = -1.66 to 1.36, k = 4; n = 677; I2 = 75%], drinks per drinking day (3 months: MD = -0.22, 95% CI = -2.51 to 2.07, k = 2, n = 359, I2 = 82%; 6-36 months: MD = -0.09, 95% CI = -0.49 to 0.30, k = 3, n = 1450, I2 = 60%) or percentage of drinking days (3 months: MD = -4.60, 95% = -21.14 to 11.94; k = 2; n = 361; I2 = 90%; 6-9 months: MD = 1.96, 95% CI = -6.54 to 10.46; k = 2; n = 818; I2 = 88%). CONCLUSION Psychosocial interventions show promise at increasing self-reported alcohol abstinence in sSA, but clinical, methodological and statistical heterogeneity across meta-analytical outcomes suggests that results should be interpreted with caution.

Fishing communities in Uganda have high rates of excessive alcohol consumption and negative health outcomes related to alcohol consumption, such as HIV acquisition and transmission and intimate partner violence victimization and perpetration. Research lacks understanding of alcohol use in Ugandan fishing communities, underlying reasons for excessive drinking among fishermen or how their community perceives negative health outcomes linked to excessive alcohol consumption. This qualitative study was conducted among Ugandan fisherfolk to determine why excessive alcohol consumption has overtaken their communities. Through analyzing in-depth interviews and focus group discussions, reasons for drinking and community perceptions of drinking were explored using the Socio Ecological Model and the Time Perspective Theory. Interviews were coded into two content themes: social influences on drinking and using alcohol to cope with stress. Participants acknowledged links between excessive alcohol consumption and negative health outcomes within their families and communities. These findings highlight the need for alcohol-related reduction interventions that are sensitive to contextual factors and self-identified contributors to problematic alcohol use within individuals and their communities. Such interventions must consider the social, ecological and economic conditions within fishing sites, focusing not only on individual-level behavioral change but also challenging the underlying structures that foster excessive alcohol consumption.

Author(s): Parriott, Andrea; Malekinejad, Mohsen; Miller, Amanda P; Horvath, Hacsi; Marks, Suzanne M; Kahn, James G | Abstract: BackgroundContact investigation is an important strategy for maintaining control of tuberculosis (TB) in the United States. However, testing and treatment outcomes specifically to foreign-born populations are poorly understood. We reviewed literature on testing and LTBI identified during contact investigations in foreign-born populations living in the US.MethodsWe conducted a comprehensive search of peer-reviewed and grey literature using Cochrane systematic review methods. We included studies with adult and adolescent populations that were at least 50% foreign-born. Pooled proportions and 95% confidence intervals (CIs) were calculated via inverse-variance weighted meta-analysis, and cumulative proportions were calculated as products of adjacent step proportions.ResultsWe identified 22 studies published between 1997 and 2014 that included at least 50% foreign-born participants. From studies of predominantly (g90%) foreign-born populations, almost all identified contacts were recruited and had valid test results, and 54.8% (95% CI 45.1-62.5%) of contacts with valid test results tested positive. From studies of majority (50% to 90%) foreign-born populations, 78.4% (95% CI 78.0-78.9%) of identified contacts were recruited, 92.0% (95% CI 91.6-92.3%) of recruited contacts had valid test results, and 38.5% (95% CI 31.9%-44.2%) of persons with valid results tested positive. These proportions varied by test type in studies of predominantly foreign-born populations. For every 1000 contacts identified in predominantly foreign-born populations, we estimate that 535 (95% CI 438 to 625) will test positive, and 354 (95% CI 244 to 453) will complete LTBI treatment. For every 1000 contacts identified in majority foreign-born populations, these estimates are 276 (95% CI 230 to 318), and 134 (95% CI 44 to 264), respectively.ConclusionsContact investigation is a high yield activity for identifying and treating foreign-born persons with LTBI, but must be complemented by other tuberculosis control activities in order to achieve continued progress toward TB elimination.

Background Homelessness increases the risk of tuberculosis (TB) disease and latent TB infection (LTBI), but persons experiencing homelessness often lack access to testing and treatment. We assessed the yield of TB testing and linkage to care for programs targeting homeless populations in the United States. Methods We conducted a comprehensive search of peer-reviewed and grey literature, adapting Cochrane systematic review methods. Two reviewers independently assessed study eligibility and abstracted key data on the testing to care cascade: number of persons reached, recruited for testing, tested for LTBI, with valid test results, referred to follow-up care, and initiating care. We used random effects to calculate pooled proportions and 95% confidence intervals (CI) of persons retained in each step via inverse-variance weighted meta-analysis, and cumulative proportions as products of adjacent step proportions. Results We identified 23 studies published between 1986 and 2014, conducted in 12 states and 15 cities. Among studies using tuberculin skin tests (TST) we found that 93.7% (CI 72.4-100%) of persons reached were recruited, 97.9% (89.3-100%) of those recruited had tests placed, 85.5% (78.6-91.3%) of those with tests placed returned for reading, 99.9% (99.6-100%) of those with tests read had valid results, and 24.7% (21.0-28.5%) with valid results tested positive. All persons testing positive were referred to follow-up care, and 99.8% attended at least one session of follow-up care. Heterogeneity was high for most pooled proportions. For a hypothetical cohort of 1000 persons experiencing homelessness reached by a targeted testing program using TST, an estimated 917 were tested, 194 were positive, and all of these initiated follow-up care. Conclusions Targeted TB testing of persons experiencing homelessness appears effective in detecting LTBI and connecting persons to care and potential treatment. Future evaluations should assess diagnostic use of interferon gamma release assays and completion of treatment, and costs of testing and treatment.

Author(s): Miller, Amanda P; Malekinejad, Mohsen; Horvath, Hacsi; Blodgett, Janet C; Kahn, James G; Marks, Suzanne M | Abstract: ContextAn estimated 21% of non-U.S.-born persons in the United States have a reactive tuberculin skin test (TST) and are at risk of progressing to TB disease. The effectiveness of strategies by healthcare facilities to improve targeted TB infection testing and linkage to care among this population is unclear.Evidence acquisitionFollowing Cochrane guidelines, we searched several sources to identify studies that assessed strategies directed at healthcare providers and/or non-U.S.-born patients in U.S. healthcare facilities.Evidence synthesisSeven studies were eligible. In a randomized controlled trial (RCT), patients with reactive TST who received reminders for follow-up appointments were more likely to attend appointments (risk ratio, RR = 1.05, 95% confidence interval 1.00-1.10), but rates of return in a quasi-RCT study using patient reminders did not significantly differ between study arms (P = 0.520). Patient-provider language concordance in a retrospective cohort study did not increase provider referrals for testing (P = 0.121) or patient testing uptake (P = 0.159). Of three studies evaluating pre and post multifaceted interventions, two increased TB infection testing (from 0% to 77%, p l .001 and RR 2.28, 1.08-4.80) and one increased provider referrals for TST (RR 24.6, 3.5-174). In another pre-post study, electronic reminders to providers increased reading of TSTs (RR 2.84, 1.53-5.25), but only to 25%. All seven studies were at high risk of bias.ConclusionsMultifaceted strategies targeting providers may improve targeted TB infection testing in non-U.S.-born populations visiting U.S. healthcare facilities; uncertainties exist due to low-quality evidence. Additional high-quality studies on this topic are needed.
