Characterizing multimorbidity in ALIVE: Comparing single and ensemble clustering methods.

Multimorbidity, defined as having 2 or more chronic conditions, is a growing public health concern, but research in this area is complicated by the fact that multimorbidity is a highly heterogenous outcome. Individuals in a sample may have a differing number and varied combinations of conditions. Clustering methods, such as unsupervised machine learning algorithms, may allow us to tease out the unique multimorbidity phenotypes. However, many clustering methods exist and choosing which to use is challenging because we do not know the true underlying clusters. Here, we demonstrate the use of 3 individual algorithms (partition around medoids, hierarchical clustering, and probabilistic clustering) and a clustering ensemble approach (which pools different clustering approaches) to identify multimorbidity clusters in the AIDS Linked to the Intravenous Experience cohort study. We show how the clusters can be compared based on cluster quality, interpretability, and predictive ability. In practice, it is critical to compare the clustering results from multiple algorithms and to choose the approach that performs best in the domain(s) that aligns with plans to use the clusters in future analyses.

Understanding motivations and resilience-associated factors to promote timely linkage to HIV care: a qualitative study among people living with HIV in western Kenya.

Understanding motivations and resilience-associated factors that help people newly diagnosed with HIV link to care is critical in the context of universal test and treat. We analyzed 30 in-depth interviews (IDI) among adults aged 18 and older in western Kenya diagnosed with HIV during home-based counseling and testing and who had linked to HIV care. A directed content analysis was performed, categorizing IDI quotations into a table based on linkage stages for organization and then developing and applying codes from self-determination theory and the concept of resilience. Autonomous motivations, including internalized concerns for one's health and/or to provide care for family, were salient facilitators of accessing care. Controlled forms of motivation, such as fear or external pressure, were less salient. Social support was an important resilience-associated factor fostering linkage. HIV testing and counseling programs which incorporate motivational interviewing that emphasizes motivations related to one's health or family combined with a social support/navigator approach, may promote timely linkage to care.

Reported xylazine exposure highly associated with overdose outcomes in a rapid community assessment among people who inject drugs in Baltimore.

BACKGROUND: Addressing xylazine harms are now a critical harm reduction priority, but relatively little epidemiological information exists to determine prevalence, magnitude, and correlates of xylazine use or related outcomes. METHODS: We conducted a rapid behavioral survey among people who inject drugs (n = 96) in Baltimore November-December 2022. Using a novel indicator of self-reported presumed xylazine effects, we examined prevalence and sociodemographic correlates of past year presumed xylazine effects and association with overdose and wound-related outcomes. Chi-square and descriptive statistics were used to examine bivariate associations overall and separately for those who reported xylazine by name and by reported fentanyl use frequency. RESULTS: Almost two-thirds (61.5%) reported experiencing xylazine effects. There were no differences by socio-demographics, but xylazine effects were more commonly reported among those who reported injecting alone (66% vs 38%%, p < 0.007) and daily fentanyl use (47% vs 24% p < 0.003). Those reporting xylazine exposure was three times as likely to report overdose (32% vs 11%, p < 0.03) and twice as likely to have used naloxone (78% vs 46%, p < 0.003). They also more commonly reported knowing someone who died of an overdose (92% vs 76%, p < 0.09) and to report an abscess requiring medical attention (36% vs 19%, p < 0.80). These associations were higher among respondents who specifically named xylazine and those who used fentanyl more frequently, but fentanyl frequency did not fully explain the heightened associations with xylazine effects. CONCLUSIONS: This study provides insight into the scope of xylazine exposure and associated health concerns among community-based PWID and suggests measures that may be instrumental for urgently needed research.

Structural and social changes due to the COVID-19 pandemic and their impact on engagement in substance use disorder treatment services: a qualitative study among people with a recent history of injection drug use in Baltimore, Maryland.

BACKGROUND: Substance use disorder treatment and recovery support services are critical for achieving and maintaining recovery. There are limited data on how structural and social changes due to the COVID-19 pandemic impacted individual-level experiences with substance use disorder treatment-related services among community-based samples of people who inject drugs. METHODS: People with a recent history of injection drug use who were enrolled in the community-based AIDS Linked to the IntraVenous Experience study in Baltimore, Maryland participated in a one-time, semi-structured interview between July 2021 and February 2022 about their experiences living through the COVID-19 pandemic (n = 28). An iterative inductive coding process was used to identify themes describing how structural and social changes due to the COVID-19 pandemic affected participants' experiences with substance use disorder treatment-related services. RESULTS: The median age of participants was 54 years (range = 24-73); 10 (36%) participants were female, 16 (57%) were non-Hispanic Black, and 8 (29%) were living with HIV. We identified several structural and social changes due the pandemic that acted as barriers and facilitators to individual-level engagement in treatment with medications for opioid use disorder (MOUD) and recovery support services (e.g., support group meetings). New take-home methadone flexibility policies temporarily facilitated engagement in MOUD treatment, but other pre-existing rigid policies and practices (e.g., zero-tolerance) were counteracting barriers. Changes in the illicit drug market were both a facilitator and barrier to MOUD treatment. Decreased availability and pandemic-related adaptations to in-person services were a barrier to recovery support services. While telehealth expansion facilitated engagement in recovery support group meetings for some participants, other participants faced digital and technological barriers. These changes in service provision also led to diminished perceived quality of both virtual and in-person recovery support group meetings. However, a facilitator of recovery support was increased accessibility of individual service providers (e.g., counselors and Sponsors). CONCLUSIONS: Structural and social changes across several socioecological levels created new barriers and facilitators of individual-level engagement in substance use disorder treatment-related services. Multilevel interventions are needed to improve access to and engagement in high-quality substance use disorder treatment and recovery support services among people who inject drugs.

Injection Behaviors and Use of Syringe Service Programs over Time among People Who Inject Drugs in Baltimore, Maryland.

Introduction: People who inject drugs (PWID) are at increased risk for infectious disease transmission, including hepatitis C and HIV. Understanding trends in injection risk behaviors and syringe service program (SSP) use over time can help improve infectious disease prevention and other harm reduction services. Methods: Using National HIV Behavioral Surveillance System data from Baltimore, Maryland, we examined changes in receptive sharing of (1) syringes, (2) injection equipment, (3) syringes to divide drugs; and (4) receipt of syringes from SSPs among PWID from 2009 to 2018 (n = 518 in 2009, n = 638 in 2012, n = 586 in 2015, and n = 575 in 2018) using unadjusted and adjusted logistic models calculated across time for the total sample. Results: The conditional probability of receptive sharing of syringes and receipt of syringes from SSPs remained relatively stable, while receptive sharing of injection equipment and receptive sharing of syringes to divide drugs dropped substantially after 2009. White race and daily injection frequency were positively associated with sharing syringes and injection equipment and negatively associated with SSP use over time. In 2015, there was a notable shift such that women were twice as likely as men to receive syringes from SSPs and less likely than men to report the use of shared syringes or equipment. Conclusion: Findings indicate overall steady or decreasing trends in injection risk and steady trends in SSP usage over time, with some notable improvements among women and indications of shifting drug market patterns. Injection-related risk behaviors remain high among White PWID and may require targeted outreach and interventions.

Drug Use-Related Discrimination in Healthcare Settings and Subsequent Emergency Department Utilization in a Prospective Cohort Study of People With a History of Injection Drug Use.

BACKGROUND:  People with a history of injection drug use face discrimination in healthcare settings that may impede their use of routine care, leading to greater reliance on the emergency department (ED) for addressing health concerns. The relationship between discrimination in healthcare settings and subsequent ED utilization has not been established in this population. METHODS:  This analysis used longitudinal data collected between January 2014 and March 2020 from participants of the ALIVE (AIDS Linked to the IntraVenous Experience) study, a community-based observational cohort study of people with a history of injection drug use in Baltimore, Maryland. Logistic regressions with generalized estimating equations were used to estimate associations between drug use-related discrimination in healthcare settings and subsequent ED utilization for the sample overall and six subgroups based on race, sex, and HIV status. RESULTS:  1,342 participants contributed data from 7,289 semiannual study visits. Participants were predominately Black (82%), mostly male (66%), and 33% were living with HIV. Drug use-related discrimination in healthcare settings (reported at 6% of study visits) was positively associated with any subsequent ED use (OR = 1.40, 95% CI: 1.15-1.72). Positive associations persisted after adjusting for covariates, including past sixth-month ED use and drug use, among the overall sample (aOR = 1.28, 95% CI: 1.04-1.59) and among some subgroups. CONCLUSIONS:  Drug use-related discrimination in healthcare settings was associated with greater subsequent ED utilization in this sample. Further exploration of mechanisms driving this relationship may help improve care and optimize healthcare engagement for people with a history of injection drug use.

Understanding healthcare engagement for people who inject drugs.

People who inject drugs (PWID) are at an increased risk of multimorbid mental health and chronic diseases, which are frequently underdiagnosed and under-treated due to systemic barriers and ongoing substance use. Healthcare engagement is essential to address these conditions and prevent excess morbidity and mortality. The goal of this study was to understand how PWID engage in care for their chronic health conditions and substance use treatment given the known historic and pervasive barriers. We conducted 24 semistructured qualitative interviews informed by the Behavioral Model for Vulnerable Populations between July-September 2019. Participants were sampled across a range of comorbidities, including co-occurring mental health disorders. Thematic analysis was conducted to explore experiences of healthcare engagement for multimorbid chronic diseases, mental health, and treatment for substance use disorder. Mean age for participants was 58 years; 63% reported male sex and 83% reported Black race. Interviews yielded themes regarding healthcare access and wraparound services, positive patient-provider relationships, service integration for substance use treatment and mental health, healthcare needs alignment, medication of opioid use disorder stigma, and acceptance of healthcare. Taken together, participants described how these themes enabled healthcare engagement. Engagement in care is crucial to support health and recovery. Clinical implications include the importance of strengthening patient-provider relationships, encouraging integration of medical and mental health services, and counseling on substance use treatment options in a non- stigmatizing manner. Additionally, policy to reimburse wrap-around support for substance use recovery can improve care engagement and outcomes related to chronic diseases, mental health, and substance use among PWID. No Patient or Public Contribution: While we acknowledge and thank ALIVE participants for their time for data collection and sharing their perspectives, no ALIVE participants, other people who use drugs, and service users were involved in data collection, analysis or interpretation of data, or in preparation of the manuscript.

Geographic variation in HCV treatment penetration among people who inject drugs in Baltimore, MD.

We evaluated geographic heterogeneity in hepatitis C virus (HCV) treatment penetration among people who inject drug (PWID) across Baltimore, MD since the advent of direct-acting antivirals (DAAs) using space-time clusters of HCV viraemia. Using data from a community-based cohort of PWID, the AIDS Linked to the IntraVenous Experience (ALIVE) study, we identified space-time clusters with higher-than-expected rates of HCV viraemia between 2015 and 2019 using scan statistics. We used Poisson regression to identify covariates associated with HCV viraemia and used the regression-fitted values to detect adjusted space-time clusters of HCV viraemia in Baltimore city. Overall, in the cohort, HCV viraemia fell from 77% in 2015 to 64%, 49%, 39% and 36% from 2016 to 2019. In Baltimore city, the percentage of census tracts where prevalence of HCV viraemia was ≥85% dropped from 57% to 34%, 25%, 22% and 10% from 2015 to 2019. We identified two clusters of higher-than-expected HCV viraemia in the unadjusted analysis that lasted from 2015 to 2017 in East and West Baltimore and one adjusted cluster of HCV viraemia in West Baltimore from 2015 to 2016. Neither differences in age, sex, race, HIV status, nor neighbourhood deprivation were able to explain the significant space-time clusters. However, residing in a cluster with higher-than-expected viraemia was associated with age, sex, educational attainment and higher levels of neighbourhood deprivation. Nearly 4 years after DAAs became available, HCV treatment has penetrated all PWID communities across Baltimore city. While nearly all census tracts experienced improvements, change was more gradual in areas with higher levels of poverty.

Characteristics of Reported Gonorrhea Diagnoses During The COVID-19 Pandemic Compared With Pre-COVID-19 Pandemic, Baltimore City, Maryland.

BACKGROUND: Sexual health service disruptions due to COVID-19 mitigation measures may have decreased gonorrhea screening and biased case-ascertainment toward symptomatic individuals. We assessed changes in reported symptoms and other characteristics among reported gonorrhea cases during pandemic versus prepandemic periods in 1 city with persistent gonorrhea transmission. METHODS: Enhanced surveillance data collected on a random sample of gonorrhea cases reported to the Baltimore City Health Department between March 2018 and September 2021 was used. Logistic regression assessed differences in case characteristics by diagnosis period (during pandemic: March 2020-September 2021; prepandemic: March 2018-September 2019). RESULTS: Analyses included 2750 (1090 during pandemic, 1660 prepandemic) gonorrhea cases, representing 11,904 reported cases. During pandemic versus prepandemic, proportionally fewer cases were reported by sexual health clinics (8.8% vs 23.2%), and more frequently reported by emergency departments/urgent care centers (23.3% vs 11.9%). Adjusting for diagnosing provider, fewer cases who were men with urethral infections (adjusted odds ratio [aOR], 0.65; 95% confidence interval [CI], 0.55-0.77), aged <18 years (aOR, 0.64; 95% CI, 0.47-0.89), and women (aOR, 0.84; 95% CI, 0.71-0.99) were reported, and cases with insurance (aOR, 1.85; 95% CI, 1.40-2.45), living with human immunodeficiency virus (aOR, 1.43; 95% CI, 1.12-1.83), or recent (≤12 months) gonorrhea history (aOR, 1.25; 95% CI, 1.02-1.53) were more frequently reported during pandemic versus prepandemic. Reported symptoms and same-day/empiric treatment did not differ across periods. CONCLUSIONS: We observed no changes in reported symptoms among cases diagnosed during pandemic versus prepandemic. Increased frequency of reported diagnoses who were insured, living with human immunodeficiency virus, or with recent gonorrhea history are suggestive of differences in care access and care-seeking behaviors among populations with high gonorrhea transmission during the pandemic.

Sexual Prejudice and Comfort to Provide Services to Men Who Have Sex with Men Among HIV Healthcare Workers in Western Kenya: Role of Interpersonal Contact.

Sexual minority men living in Africa, where many countries criminalize same-sex behavior, are vulnerable to HIV and experience significant barriers to HIV care. Sexual prejudice in healthcare settings is a key contributor to these barriers. Building on social psychological models of prejudice and interpersonal contact at the clinic, we examined the associations between healthcare workers' sexual prejudice and their comfort to provide care to MSM, and assessed the moderating role of workers' prior interpersonal contact with MSM. A cross-sectional survey of 147 healthcare workers varying in level of training and expertise working in HIV care organizations was conducted in western Kenya. Sexual prejudice was negatively associated with comfort to provide care to MSM. Prior interpersonal contact with MSM moderated the association between sexual prejudice and comfort to provide care to MSM among nurses/counselors, such that those with low prior contact and high sexual prejudice were the most uncomfortable providing care to MSM. Interventions are needed to address sexual prejudice and encourage positive forms of interpersonal contact with MSM, especially with nurses and counselors who might have more and varied patient interactions, to improve access to the continuum of HIV prevention and care for MSM in Kenya.

Continuity of Care is Associated with Higher Appointment Adherence Among HIV Patients in Low Clinician-to-Patient Ratio Facilities in Western Kenya.

We sought to determine the relationship between continuity of care and adherence to clinic appointments among patients receiving HIV care in high vs. low clinician-to-patient (C:P) ratios facilities in western Kenya. This retrospective analysis included 12,751 patients receiving HIV care from the Academic Model Providing Access to Healthcare (AMPATH) program, between February 2016-2019. We used logistic regression analysis with generalized estimating equations to estimate the relationship between continuity of care (two consecutive visits with the same provider) and adherence to clinic appointments (within 7 days of a scheduled appointment) over time. Adjusting for covariates, patients in low C:P ratio facilities who had continuity of care, were more likely to be adherent to their appointments compared to those without continuity (adjusted odds ratio = 1.50; 95% confidence interval, 1.33-1.69). Continuity in HIV care may be a factor in clinical adherence among patients in low C:P ratio facilities and should therefore be promoted.

Adverse childhood experiences and comorbidity in a cohort of people who have injected drugs.

BACKGROUND: Childhood adversity is associated with the onset of harmful adult substance use and related health problems, but most research on adversity has been conducted in general population samples. This study describes the prevalence of adverse childhood experiences in a cohort of people who have injected drugs and examines the association of these adverse experiences with medical comorbidities in adulthood. METHODS: Six hundred fifty three adults were recruited from a 30-year cohort study on the health of people who have injected drugs living in and around Baltimore, Maryland (Median age = 47.5, Interquartile Range = 42.3-52.3 years; 67.3% male, 81.1% Black). Adverse childhood experiences were assessed retrospectively in 2018 via self-report interview. Lifetime medical comorbidities were ascertained via self-report of a provider diagnosis. Multinomial logistic regression with generalized estimating equations was used to examine the association between adversity and comorbid conditions, controlling for potential confounders. RESULTS: Two hundred twelve participants (32.9%) reported 0-1 adverse childhood experiences, 215 (33.3%) reported 2-4, 145 (22.5%) reported 5-9, and 72 (11.1%) reported ≥10. Neighborhood violence was the most commonly reported adversity (48.5%). Individuals with ≥10 adverse childhood experiences had higher odds for reporting ≥3 comorbidities (Adjusted Odds Ratio = 2.9, 95% CI = 1.2 - 6.8, p = .01). CONCLUSIONS: Among people who have injected drugs, adverse childhood experiences were common and associated with increased occurrence of self-reported medical comorbidities. Findings highlight the persistent importance of adversity for physical health even in a population where all members have used drugs and there is a high burden of comorbidity.

Prevalence and correlates of using opioids alone among individuals in a residential treatment program in Michigan: implications for overdose mortality prevention.

BACKGROUND: Avoiding use of opioids while alone reduces overdose fatality risk; however, drug use-related stigma may be a barrier to consistently using opioids in the presence of others. METHODS: We described the frequency of using opioids while alone among 241 people reporting daily heroin use or non-prescribed use of opioid analgesic medications (OAMs) in the month before attending a substance use disorder treatment program in the Midwestern USA. We investigated drug use-related stigma as a correlate of using opioids while alone frequently (very often vs. less frequently or never) and examined overdose risk behaviors associated with using opioids while alone frequently, adjusted for sociodemographic and clinical characteristics. RESULTS: The sample was a median age of 30 years, 34% female, 79% white, and nearly all (91%) had experienced an overdose. Approximately 63% had used OAMs and 70% used heroin while alone very often in the month before treatment. High levels of anticipated stigma were associated with using either opioid while alone very often (adjusted PR: 1.20, 95% CI: 1.04-1.38). Drinking alcohol and taking sedatives within two hours of OAMs very often (vs. less often or never) and using OAMs in a new setting very often (vs. less often or never) were associated with using OAMs while alone very often. Taking sedatives within two hours of using heroin and using heroin in a new setting very often (vs. less often or never) were associated with using heroin while alone very often. CONCLUSION: Anticipated stigma, polysubstance use, and use in a new setting were associated with using opioids while alone. These findings highlight a need for enhanced overdose harm reduction options, such as overdose detection services that can initiate an overdose response if needed. Addressing stigmatizing behaviors in communities may reduce anticipated stigma and support engagement and trust in these services.

Implementing enhanced patient care to promote patient engagement in HIV care in a rural setting in Kenya.

BACKGROUND: Patient engagement is effective in promoting adherence to HIV care. In an effort to promote patient-centered care, we implemented an enhanced patient care (EPC) intervention that addresses a combination of system-level barriers including provider training, continuity of clinician-patient relationship, enhanced treatment dialogue and better clinic scheduling. We describe the initial implementation of the EPC intervention in a rural HIV clinic in Kenya, and the factors that facilitated its implementation. METHODS: The intervention occurred in one of the rural Academic Model Providing Healthcare (AMPATHplus) health facilities in Busia County in the western region of Kenya. Both qualitative and quantitative data were collected through training and meeting proceedings/minutes, a patient tracking tool, treatment dialogue and a peer confirmation tool. Qualitative data were coded and emerging themes on the implementation and adaptation of the intervention were developed. Descriptive analysis including percentages and means were performed on the quantitative data. RESULTS: Our analysis identified four key factors that facilitated the implementation of this intervention. (1) The smooth integration of the intervention as part of care that was facilitated by provider training, biweekly meetings between the research and clinical team and having an intervention that promotes the health facility agenda. (2) Commitment of stakeholders including providers and patients to the intervention. (3) The adaptability of the intervention to the existing context while still maintaining fidelity to the intervention. (4) Embedding the intervention in a facility with adequate infrastructure to support its implementation. CONCLUSIONS: This analysis demonstrates the value of using mixed methods approaches to study the implementation of an intervention. Our findings emphasize how critical local support, local infrastructure, and effective communication are to adapting a new intervention in a clinical care program.

The Relationship Between Household Microfinance Group Participation and Vaccine Adherence Among Children in Rural Western Kenya.

INTRODUCTION: High childhood vaccine adherence is critical for disease prevention, and poverty is a key barrier to vaccine uptake. Interventions like microfinance programs that aim to lift individuals out of poverty could thus improve vaccine adherence of the children in the household. BIGPIC Family Program in rural Western Kenya provides group-based microfinance services while working to improve access to healthcare and health screenings for the local community. The aim of the present paper is to evaluate the association between household participation in BIGPIC's microfinance program and vaccine adherence among children in the household. We hypothesize that microfinance group participation will have a positive impact on vaccine adherence among children in the household. METHODS: From 2018 to 2019, we surveyed a sample of 300 participants from two rural communities in Western Kenya, some of whom were participants in the BIGPIC Family's microfinance program. The primary outcome of interest was vaccine adherence of children in the household. Log-binomial models were used to estimate the relationship between microfinance group participation and vaccine adherence, adjusted for key covariates. We also assessed whether the relationship differed by gender of the adult respondent. RESULTS: Microfinance group members were more likely to have all children in their households fully vaccinated [aPR (95% CI): 1.68 (1.20,2.35)] compared to non-microfinance group members. Further, the association was stronger when women were the microfinance members [PR (95% CI): 1.87 (1.27,2.76)] compared to men [PR (95% CI): 1.24 (0.81,1.90)]. CONCLUSIONS: Microfinance participation was associated with higher childhood vaccine adherence in rural Western Kenya. Microfinance interventions should be further explored as strategies to improve child health and well-being in low- and middle-income countries.

Barriers to ART adherence among school students living with HIV in Kenya.

HIV has transformed from a serious acute illness with high rates of morbidity and mortality to a fairly easily managed chronic disease. However, children and adolescents living with HIV are yet to achieve similar improvement in their HIV care outcomes compared to adults. There have been a number of studies assessing the reasons for slower improvement in these age categories, mainly focusing on health systems, drug- and family- related barriers to ART adherence in children. We sought to explore school-related barriers to adherence through in-depth interviews with students living with HIV (SLHIV) aged 13-17 years who had fully disclosed their HIV status in western Kenya. Data was analysed using NVivo 8™. The study found that stigmatisation in the form of negative discussions and alienation, fear of unintended disclosure (due to the drug packaging and lack of privacy while taking their pills) were barriers to ART adherence among these SLHIV. Other barriers included challenges with drug storage while in school and the complexity of coordinating school and clinic-related activities and a lack of structured support systems in schools. In addition to hindering their adherence to ART, these barriers resulted in negative emotions (anger, sadness, frustration) and affected school performance. This study found fairly serious barriers to ART adherence among SLHIV, which calls for structured communication and coordinated support between government ministries of health and education in Kenya.

Prevalence and Correlates of Providing and Receiving Assistance With the Transition to Injection Drug Use.

Preventing the transition to injection drug use is an important public health goal, as people who inject drugs (PWID) are at high risk for overdose and acquisition of infectious disease. Initiation into drug injection is primarily a social process, often involving PWID assistance. A better understanding of the epidemiology of this phenomenon would inform interventions to prevent injection initiation and to enhance safety when assistance is provided. We conducted a systematic review of the literature to 1) characterize the prevalence of receiving (among injection-naive persons) and providing (among PWID) help or guidance with the first drug injection and 2) identify correlates associated with these behaviors. Correlates were organized as substance use behaviors, health outcomes (e.g., human immunodeficiency virus infection), or factors describing an individual's social, economic, policy, or physical environment, defined by means of Rhodes' risk environments framework. After screening of 1,164 abstracts, 57 studies were included. The prevalence of receiving assistance with injection initiation (help or guidance at the first injection) ranged 74% to 100% (n = 13 estimates). The prevalence of ever providing assistance with injection initiation varied widely (range, 13%-69%; n = 13 estimates). Injecting norms, sex/gender, and other correlates classified within Rhodes' social risk environment were commonly associated with providing and receiving assistance. Nearly all PWID receive guidance about injecting for the first time, whereas fewer PWID report providing assistance. Substantial clinical and statistical heterogeneity between studies precluded meta-analysis, and thus local-level estimates may be necessary to guide the implementation of future psychosocial and sociostructural interventions. Further, estimates of providing assistance may be downwardly biased because of social desirability factors.

The relationship between a microfinance-based healthcare delivery platform, health insurance coverage, health screenings, and disease management in rural Western Kenya.

BACKGROUND: Structural barriers often prevent rural Kenyans from receiving healthcare and diagnostic testing. The Bridging Income Generation through grouP Integrated Care (BIGPIC) Family intervention facilitates microfinance groups, provides health screenings and treatment, and delivers education about health insurance coverage to address some of these barriers. This study evaluated the association between participation in BIGPIC microfinance groups and health screening/disease management outcomes. METHODS: From November 2018 to March 2019, we interviewed a sample of 300 members of two rural communities in Western Kenya, 100 of whom were BIGPIC microfinance members. We queried participants about their experiences with health screening and disease management for HIV, diabetes, hypertension, tuberculosis, and cervical cancer. We used log-binomial regression models to estimate the association between microfinance membership and each health outcome, adjusting for key covariates. RESULTS: Microfinance members were more likely to be screened for most of the health conditions we queried, including those provided by BIGPIC [e.g. diabetes: aPR (95% CI): 3.46 (2.60, 4.60)] and those not provided [e.g. cervical cancer: aPR (95% CI): 2.43 (1.21, 4.86)]. Microfinance membership was not significantly associated with health insurance uptake and disease management outcomes. CONCLUSIONS: In rural Kenya, a microfinance program integrated with healthcare delivery may be effective at increasing health screening. Interventions designed to thoughtfully and sustainably address structural barriers to healthcare will be critical to improving the health of those living in low-resource settings.

Durable HIV Suppression Among People Who Inject Drugs From a Community-Based Cohort Study in Baltimore, Maryland, 1997-2017.

People who inject drugs (PWID) face disparities in human immunodeficiency virus (HIV) treatment outcomes and may be less likely to achieve durable viral suppression. We characterized transitions into and out of viral suppression from 1997 to 2017 in a long-standing community-based cohort study of PWID, the AIDS Link to Intravenous Experience (ALIVE) Study, analyzing HIV-positive participants who had made a study visit in or after 1997. We defined the probabilities of transitioning between 4 states: 1) suppressed, 2) detectable, 3) lost to follow-up, and 4) deceased. We used multinomial logistic regression analysis to examine factors associated with transition probabilities, with a focus on transitions from suppression to other states. Among 1,061 participants, the median age was 44 years, 32% were female, 93% were African-American, 59% had recently injected drugs, and 28% were virologically suppressed at baseline. Significant improvements in durable viral suppression were observed over time; however, death rates remained relatively stable. In adjusted analysis, injection drug use and homelessness were associated with increased virological rebound in earlier time periods, while only age and race were associated with virological rebound in 2012-2017. Opioid use was associated with an increased risk of death following suppression in 2012-2017. Despite significant improvements in durable viral suppression, subgroups of PWID may need additional efforts to maintain viral suppression and prevent premature mortality.

Microfinance Interventions and HIV Treatment Outcomes: A Synthesizing Conceptual Framework and Systematic Review.

BACKGROUND: Microfinance interventions have the potential to improve HIV treatment outcomes, but the mechanisms through which they operate are not entirely clear. OBJECTIVES: To construct a synthesizing conceptual framework for the impact of microfinance interventions on HIV treatment outcomes using evidence from our systematic review. METHODS: We conducted a systematic review by searching electronic databases and journals from 1996 to 2018 to assess the effects of microfinance interventions on HIV treatment outcomes, including adherence, retention, viral suppression, and CD4 cell count. RESULTS: All studies in the review showed improved adherence, retention, and viral suppression, but varied in CD4 cell count following participation in microfinance interventions-overall supporting microfinance's positive role in improving HIV treatment outcomes. Our synthesizing conceptual framework identifies potential mechanisms through which microfinance impacts HIV treatment outcomes through hypothesized intermediate outcomes. CONCLUSION: Greater emphasis should be placed on assessing the effect mechanisms and intermediate behaviors to generate a sound theoretical basis for microfinance interventions.
