A community health worker and mobile health app intervention to improve adherence to HIV medication among persons with HIV: the CHAMPS study protocol

BackgroundPersons with HIV (PWH) can now achieve a near-normal life expectancy due to antiretroviral therapy (ART). Despite widespread availability of ART in the United States (US), many of the country’s approximate 1.1 million PWH are not achieving viral suppression due to poor ART adherence. Viral suppression rates are particularly low in Alabama (AL, 62%) and New York City (NYC, 67%). There is mixed evidence on the efficacy of community health workers (CHW) and mHealth interventions for improving ART adherence and viral suppression in PWH thus, we sought to combine these interventions and test the efficacy for improving health outcomes in PWH.MethodsThe CHAMPS study is a two-arm randomized controlled trial among 300 PWH with suboptimal primary care appointment adherence (n = 150 in AL and 150 in NYC) over the course of 12 months. Participants are randomly assigned to CHAMPS (intervention) or a standard-of-care (control) arm. Participants in the intervention arm are given a CleverCap pill bottle that syncs to the WiseApp to track medication adherence, reminds users to take their medication at a set time, and enables communication with CHW. All participants complete baseline, 6-month, and 12-month follow-up visits where surveys are administered and, CD4 and HIV-1 viral load are obtained through blood draw.DiscussionMaintaining ART adherence has significant implications in HIV management and transmission. mHealth technologies have been shown to optimize the provision of health services, produce positive changes in health behavior, and significantly improve health outcomes. CHW interventions also provide personal support to PWH. The combination of these strategies may provide the necessary intensity to increase ART adherence and clinic attendance among PWH at highest risk for low engagement. Delivering care remotely enables CHW to contact, assess, and support numerous participants throughout the day, reducing burden on CHW and potentially improving intervention durability for PWH. The adoption of the WiseApp coupled with community health worker sessions in the CHAMPS study has the potential to improve HIV health outcomes, and will add to the growing knowledge of mHealth and CHW efforts to improve PWH medication adherence and viral suppression.Trial registrationThis trial was registered with Clinicaltrials.gov (NCT04562649) on 9/24/20.

A Type II hybrid effectiveness-implementation study of an integrated CHW intervention to address maternal healthcare in rural Nepal.

Skilled care during pregnancy, childbirth, and postpartum is essential to prevent adverse maternal health outcomes, yet utilization of care remains low in many resource-limited countries, including Nepal. Community health workers (CHWs) can mitigate health system challenges and geographical barriers to achieving universal health coverage. Gaps remain, however, in understanding whether evidence-based interventions delivered by CHWs, closely aligned with WHO recommendations, are effective in Nepal's context. We conducted a type II hybrid effectiveness-implementation, mixed-methods study in two rural districts in Nepal to evaluate the effectiveness and the implementation of an evidence-based integrated maternal and child health intervention delivered by CHWs, using a mobile application. The intervention was implemented stepwise over four years (2014-2018), with 65 CHWs enrolling 30,785 families. We performed a mixed-effects Poisson regression to assess institutional birth rate (IBR) pre-and post-intervention. We used the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework to evaluate the implementation during and after the study completion. There was an average 30% increase in IBR post-intervention, adjusting for confounding variables (p<0.0001). Study enrollment showed 35% of families identified as dalit, janjati, or other castes. About 78-89% of postpartum women received at least one CHW-counseled home visit within 60 days of childbirth. Ten (53% of planned) municipalities adopted the intervention during the study period. Implementation fidelity, measured by median counseled home visits, improved with intervention time. The intervention was institutionalized beyond the study period and expanded to four additional hubs, albeit with adjustments in management and supervision. Mechanisms of intervention impact include increased knowledge, timely referrals, and longitudinal CHW interaction. Full-time, supervised, and trained CHWs delivering evidence-based integrated care appears to be effective in improving maternal healthcare in rural Nepal. This study contributes to the growing body of evidence on the role of community health workers in achieving universal health coverage.

Observational Analysis of a Generalized, Health Plan-led Community Health Worker Intervention in Medicaid.

In 2018, a Medicaid managed care plan launched a new community health worker (CHW) initiative in several counties within a state, designed to improve the health and quality of life of members who could benefit from additional services. The CHW program involved telephonic and face-to-face visits from CHWs who provided support, empowerment, and education to members, while identifying and addressing health and social issues. The primary objective of this study was to evaluate the impact of a generalized (not disease-specific), health plan-led CHW program on overall healthcare use and spending. This retrospective cohort study used data from adult members who received the CHW intervention (N = 538 participants) compared to those who were identified for participation but were unable to be reached (N = 435 nonparticipants). Outcomes measures included healthcare utilization, including scheduled and emergency inpatient admissions, emergency department (ED) visits, and outpatient visits; and healthcare spending. The follow-up period for all outcome measures was 6 months. Using generalized linear models, 6-month change scores were regressed on baseline characteristics to adjust for between-group differences (eg, age, sex, comorbidities) and an indicator for group. Program participants experienced a greater increase in outpatient evaluation and management visits (0.09 per member per month [PMPM]) than the comparison group during the first 6 months of the program. This greater increase was observed across in-person (0.07 PMPM), telehealth (0.03 PMPM), and primary care (0.06 PMPM) visits. There was no observed difference in inpatient admissions, ED utilization or allowed medical spending and pharmacy spending. A health plan-led CHW program successfully increased multiple forms of outpatient utilization in a historically disadvantaged population of patients. Health plans may be particularly well positioned to finance, sustain, and scale programs that address social drivers of health.

PS-P16-8: DIAGNOSIS AND TREATMENT OF HYPERTENSION BY COMMUNITY HEALTH WORKERS IN RURAL NEPAL: MAIN RESULTS OF THE MUTU TRIAL

Objective: To evaluate the effectiveness and safety of a community health worker intervention for diagnosing and managing hypertension (HTN) in rural Nepal. Design &amp; Methods: We conducted a quasi-experimental study in two rural municipalities in Nepal, assigning one as an active site (7 communities) and the other as a comparison site (8 communities, which received enhanced usual care). The intervention in the active site involved three home visits for blood pressure (BP) monitoring and counseling by trained community-based community health workers (Female Community Health Volunteers) and treatment of HTN by trained community health workers based in government Health Posts under physician supervision using a simplified protocol with amlodipine. The comparison site received one home visit by Female Community Health Volunteers. A total of 1428 adults with untreated HTN (systolic BP of 140–179 and/or diastolic BP of 90–119 mm Hg) were enrolled. The primary outcome was a reduction in systolic BP at 12 months (measured in 94% of enrolled participants), and the secondary outcome was HTN control rate defined as BP &lt; 140/90 mm Hg. Results: The mean baseline systolic BP was 145.4 mm Hg in the active site (n = 576, 46% women) and 146.9 mm Hg in the comparison site (n = 760, 46% women). At 12 months, while BP was lower in both sites, mean SBP fell more in the active site [net mean difference of -11.0 mm Hg, (95% CI: -12.5 to -9.6; P &lt; 0.001)] (Table). The corresponding net difference in DBP was -6.0 mm Hg (95% CI: -6.8 to -5.1; P &lt; 0.001). HTN control and medication treatment were both higher in the active site compared to the comparison site (Table). There were four deaths unrelated to the intervention (2 in the comparison site and 2 in the active site). Conclusion: In rural communities of Nepal, a health system intervention with trained community health workers diagnosing and treating hypertension, supervised by a physician, substantially lowered BP and achieved higher control rates compared to usual care. The success of this intervention provides strong support of enhanced roles for community health workers to diagnose and treat HTN. Scaling up such interventions could potentially address the major workforce gaps that lead to low HTN control rates, particularly in rural communities of low and middle-income countries.

ESPO AND BEHAVIORAL AND SOCIAL SCIENCES SECTION SYMPOSIUM: TAILORING INTERVENTIONS TO REACH AND MEET THE DIVERSE NEEDS OF DIVERSE CAREGIVERS

Abstract Family caregiving cuts across populations, making caregivers a highly diverse population in terms of culture, family organization, care situations, and more. A 2021 report from the National Academies of Sciences Engineering and Medicine reinforces the need to develop and test tailored interventions in order to successfully reach and support family caregivers. Yet, there is limited practical guidance to help researchers to develop intervention programs tailored to the diverse needs of family caregivers. This symposium endeavors to address this gap by sharing accounts from researchers who have effectively tailored existing interventions to meet the diverse needs of diverse caregivers, as well as those who collaboratively worked alongside family caregivers in order to build a tailored program from the ground up. To begin, Kristin Cloyes, PhD MN RN will describe a study where she examines alignment between LGTBQ+ hospice family caregivers and other members of the hospice care teams, as it relates to support and communication needs. Next, Jung-Ah Lee, PhD, RN, FGSA, FAAN, will describe the experiences of racially and ethnically diverse caregivers who received a community health worker intervention to access resources tailored to their language needs. Jaime Perales-Puchalt, PhD, MPH, will describe the results of CuidaTEXT intervention study, which used tailored Short Messaging Service-based text message to deliver support to Latin family caregivers. Lastly, Ishan Williams, PhD, FGSA, will present on findings from research on how community engagement as well as culturally informed intervention can improve the representation of family caregivers, especially African American caregivers, in caregiving research studies

The impact of a community health worker intervention on uptake of antenatal care: a cluster-randomized pragmatic trial in Dar es Salaam.

The provision of high-quality antenatal care (ANC) is important for preventing maternal and newborn mortality and morbidity, but only around half of pregnant women in Tanzania attended four or more ANC visits in 2019. Although there is emerging evidence on the benefit of community health worker (CHW) interventions on ANC uptake, few large-scale pragmatic trials have been conducted. This pragmatic cluster-randomized trial, implemented directly through the public sector health system, assessed the impact of an intervention that trained public sector CHWs to promote the uptake of ANC. We randomized 60 administrative wards in Dar es Salaam to either a targeted CHW intervention or a standard of care. The impact of the intervention was assessed using generalized estimating equations with an independent working correlation matrix to account for clustering within wards. A total of 243 908 women were included in the analysis of our primary outcome of four or more ANC visits. The intervention significantly increased the likelihood of attending four or more ANC visits [relative risk (RR): 1.42; 95% confidence interval (CI): 1.05, 1.92] and had a modest beneficial effect on the total number of ANC visits (percent change: 7.7%; 95% CI: 0.2%, 15.5%). While slightly more women in the intervention arm attended ANC in their first trimester compared with the standard-of-care arm (19% vs 18.7%), the difference was not significant (RR: 1.02; 95% CI: 0.84, 1.22). Our findings suggest that trained CHWs can increase attendance of ANC visits in Dar es Salaam and similar settings. However, additional interventions appear necessary to promote the early initiation of ANC. This study demonstrates that routine health system data can be leveraged for outcome assessment in trials and programme evaluation and that the results are likely superior, both in terms of bias and precision, to data that are collected specifically for science.

Effect of community-level intervention on antenatal care attendance: a quasi-experimental study among postpartum women in Eastern Uganda

ABSTRACT Background Early Initiation of antenatal care (ANC) and at least four visits during pregnancy allow screening and support for a healthy lifestyle and self-care during pregnancy however, community-directed interventions to improve access to these services are rarely explored. Objective To assess the effect of community health worker (CHW) involvement on utilisation of antenatal services during pregnancy in resource-constrained rural settings in Uganda. Methods We conducted a quasi-experimental evaluation study among mothers from Eastern Uganda. We used Difference in Differences (DiD) analysis to assess the effect of CHW intervention on ANC attendance. Components of the intervention included community dialogues and empowering CHWs to educate pregnant women about using maternal health services. The primary endpoints were early initiation of ANC and completion of at least 4 ANC visits. Results Overall, the intervention significantly improved attendance of ≥ 4 ANC visits (DiD = 5.5%). The increase was significant in both intervention and comparison areas (46.2–64.4% vs. 54.1–66.8%, respectively), with slightly greater gains in the intervention area. Other elements that predicted ≥4 ANC attendance besides the intervention were post-primary education (PR1.14, 95%CI 1.02–1.30), higher wealth quintile (PR1.17, 95%CI 1.06–1.30), and early initiation of ANC (PR1.58, 95%CI 1.49–1.68). The intervention did not significantly improve early initiation of ANC (DiD =-1.3%). Instead, early initiation of ANC was associated with higher husband education (PR1.19,95%CI 1.02–1.39), larger household size (PR = 0.81, 95%CI 0.70–0.95), and higher wealth index (PR1.19,95%CI 1.03–1.37). Conclusions The CHW intervention improved attendance of at least 4 ANC visits but not early initiation of ANC. There is need to promote CHW-led health education to increase attendance at 4+ ANC visits, but other approaches to promote early initiation are urgently required.

Promoting Physical Activity Among Immigrant Asian Americans: Results from Four Community Health Worker Studies.

Racial/ethnic minorities have demonstrated lower rates of physical activity (PA) than non-Hispanic Whites. This study examined outcomes in PA measures after participation in a community health worker (CHW) intervention. We performed a secondary data analysis from four randomized controlled trials utilizing CHWs (n = 842) in New York City (Bangladeshi-diabetes management, Filipino-hypertension management, and Korean and Asian Indian-diabetes prevention). Outcomes included total weekly PA, PA self-efficacy, PA barriers, and PA social interaction. Each measure was examined at baseline and study endpoint. Generalized estimating equation models were fitted to assess the repeated measures over time, while accounting for study group and socio-demographic factors. Moderate PA, recommended PA, and self-efficacy increased significantly among treatment group participants. PA social interaction increased significantly among Filipinos and Asian Indians. In adjusted regression analysis, time x group interaction was significant for all PA outcomes except for PA barriers. Culturally-adapted lifestyle interventions may potentially improve PA-related outcomes in Asian immigrant communities. Trial registration at ClinicalTrials.gov includes: NCT03530579 (RICE Project), NCT02041598 (DREAM Project), and NCT03100812 (AsPIRE).

Evaluation of interventions for essential newborn care practices at home-based delivery in India

Abstract India has the largest share of neonatal mortality, accounting for 21.7 per 1,000 in 2019, while the global goal is at least 12 per 1,000 by 2030. More than 20% of deliveries still occur at home in India for various reasons. Several national interventions were designed to ensure essential practices even at home by engaging skilled birth attendants (SBAs), antenatal care (ANC), and community health workers (CHWs). This study evaluates the effectiveness of these interventions on essential newborn care practices (EP); clean cord care, thermal care, and breastfeeding. Using data from the 2015-2016 India Demographic and Health Survey (n = 9,273), this study employs structural equation modeling to confirm the relationship between SBA, ANC, CHWs` counseling, and EP, including indirect effects of ANC and CHWs and moderating effects of women's empowerment. The results show that SBA and ANC have significant direct effects (standardised coefficient=0.105 and 0.056, respectively) on EP, and ANC and CHWs have significant indirect effects (0.015 and 0.004) in the well-fitted model (CFI=0.938, TLI=0.920, RMSEA (upper 90% CI)=0.028 (0.029), SRMR=0.044). The empowerment-related factors which had a significant positive moderating effect on the paths from SBA to EP and from ANC to EP are decision-making power (0.007, 0.003), allowed mobility (0.002, 0.001), and education (0.009, 0.004). More than 90% of EP variance is not associated with the factors in this model (standardised coefficient=0.958). SBA demonstrated the most considerable effectiveness for EP, while ANCs and CHW indirectly impacted EP. Improving women's empowerment can be an effective strategy to enhance EP. Previous literature said that the other factors explaining EP could be quality of care, other interventions for a safe birth, and cultural characteristics. Policymakers are recommended to consider comprehensive factors to address barriers to safe home birth and design CHW's intervention to persuade SBA. Key messages

Health literacy, health outcomes and community health worker utilization: a cohort study in HIV primary care

BackgroundPeople with HIV (PWH) have complex needs, and those with limited health literacy consistently have poorer HIV-related knowledge and health outcomes. One strategy to facilitate better outcomes for PWH is the inclusion of community health workers (CHWs) into care teams. This cohort study examines the effect of health literacy on clinical outcomes and utilization of CHW services among PWH enrolled in a CHW intervention. The secondary aim is to characterize most common purposes of CHW encounters.MethodsPWH (n = 209) enrolled in a CHW intervention with completed 6-month follow-up evaluation visits were included. Health literacy level was measured at baseline with the BRIEF tool and categorized into inadequate, marginal, and adequate health literacy. Adjusted logistic regressions assessed the effect of health literacy on viral load suppression, HIV primary care visits at 6-month follow-up, CHW utilization and purpose of CHW encounter. Purpose of CHW encounters included logistical support, accompany to appointment, transportation coordination, concrete services, coaching, and emotional support. Linear regression assessed the association between purpose of CHW encounters and CHW utilization.ResultsIndividuals with inadequate health literacy were more likely to receive coaching from CHWs (p = 0.029), and individuals with marginal health literacy were more likely to have an HIV primary care visit at 6 months (p = 0.044). Individuals receiving transportation coordination, concrete services, coaching, and emotional support had more total CHW encounters.ConclusionsPurpose of encounter was highly correlated with frequency of CHW encounters, while health literacy status was not. This suggests individuals receiving these services require more assistance from CHWs, regardless of health literacy level. Training CHWs to conduct comprehensive social needs assessment and screening for risk factors at the initial visit with clients can identify resources and guide CHW service delivery as part of the care team.

Self-reported outcomes of a randomized trial comparing three community health worker interventions for diabetes prevention among Cambodian Americans with depression

ObjectiveCambodian Americans have complex, interrelated and persistent medical and mental health problems stemming from genocide and the social determinants of health. We examined changes in multiple domains of self-reported health outcomes from a diabetes prevention trial. Methods: Cambodian Americans with depression and high risk for diabetes (n = 188) were randomized to one of three community health worker interventions: lifestyle vs lifestyle plus medication therapy management vs social services. Assessments were at baseline, 12- and 15-months. Results: The typical participant was 55 years old, female, earned below $20,000 annually, and had 7 years of education. About one-third were taking antidepressant medication and over half had elevated depressive symptoms. Relative to social services, lifestyle and lifestyle plus medication therapy management were both similarly effective at increasing diabetes knowledge, nutrition habits, sleep quality and decreasing pain; 2) lifestyle alone was superior to social services for self-reported health; and, 3) all three groups showed improved anxiety and insomnia. There were no effects on physical activity or physical functioning. Conclusion: Community health worker interventions have multiple benefits beyond delaying diabetes. Practice Implications: Health promotion programs that are designed and delivered appropriately can impact even hard to reach and hard to treat groups.

Community health worker intervention improves early childhood vaccination rates: results from a propensity-score matching evaluation

BackgroundArizona’s Health Start Program is a statewide community health worker (CHW) maternal and child health home visiting intervention. The objective of this study was to test if participation in Health Start during 2006–2016 improved early childhood vaccination completion rates.MethodsThis retrospective study used 11 years of administrative, birth certificate, and immunization records. Propensity score matching was used to identify control groups, based on demographic, socioeconomic, and geographic characteristics. Results are reported by historically disadvantaged subgroups and/or with a history of low vaccine uptake, including Hispanic/Latinx and American Indian children, and children of low socioeconomic status and from rural areas, children with teen mothers and first-born children. The average treatment-on-the-treated (ATT) effect estimated the impact of Health Start on timely completion of seven early childhood vaccine series: diphtheria/tetanus toxoids and acellular/whole-cell pertussis (DTaP/DTP), Haemophilus influenzae type b (Hib), hepatitis B (Hep. B), measles-mumps-rubella (MMR), pneumococcal conjugate vaccine (PCV13), poliovirus, and varicella.ResultsVaccination completion rates (by age five) were 5.0% points higher for Health Start children as a group, and on average 5.0% points higher for several subgroups of mothers: women from rural border counties (ATT 5.8), Hispanic/Latinx women (ATT 4.8), American Indian women (ATT 4.8), women with less than high school education (ATT 5.0), teen mothers (ATT 6.1), and primipara women (ATT 4.5), compared to matched control groups (p-value ≤ 0.05). Time-to-event analyses show Health Start children complete vaccination sooner, with a hazard rate for full vaccination 13% higher than their matches.ConclusionA state-operated home visiting intervention with CHWs as the primary interventionist can effectively promote early childhood vaccine completion, which may reduce the incidence of preventable diseases and subsequently improve children’s health. Effects of CHW interventions on vaccination uptake is particularly relevant given the rise in vaccine-preventable diseases in the US and globally.Trial registrationApproved by the University of Arizona Research Institutional Review Board (Protocol 1701128802), 25 January 2017.

Improving diabetes care of community-dwelling underserved older adults.

Diabetes care among rural underserved older adults is negatively affected by social determinants of health (SDOH). Although there is an increased awareness of this problem, evidence-based clinical and community interventions are not widely integrated. This project implemented telemedicine and community health worker (CHW) interventions to improve diabetes management and outcomes. One in five older adults with diabetes mellitus (DM) at a Federally Qualified Health Center in southwest Ohio has uncontrolled disease, largely due to their limited resources and ability to participate in routine clinical management. This quality improvement project used a pre-post intervention design. Participants were adults aged ≥65 years with uncontrolled DM type 1 or 2. The outcomes of interest included A1C values, diabetes self-care activities, diabetes knowledge, and patient and health care provider (HCP) satisfaction levels. The project involved biweekly CHW home visits and diabetes self-management education for 12 weeks. The CHWs, with supervision from a nurse practitioner, conducted SDOH assessments and basic education, and facilitated same-day telemedicine appointments with the HCP to reinforce disease management. The A1C levels and diabetes knowledge of older adults significantly improved after three months. However, there were no statistically significant changes in diabetes self-care activities. The patients and HCPs were highly satisfied with the project interventions. This project delivered patient-centered and equitable diabetes care services that were previously unavailable to underserved older patients, while demonstrably improving outcomes. Future research should evaluate the cost-effectiveness, long-term impact, and sustainability of the project in other primary care settings.

Behind Closed Doors: A Thematic Analysis of Diabetes Community Health Worker Home Visit Content.

The present work studies how community health workers (CHWs) perform the role of educator and how this relates to the implementation of other CHW roles, skills, and qualities. Prior studies on this topic have relied on interviews or focus groups rather than analysis of CHW interactions. We conducted a thematic analysis of 24 transcripts of conversations occurring between CHWs and participants during home visits as part of the Mexican American Trial of Community Health Workers, a randomized controlled trial that improved clinical outcomes among low-income Mexican American adults with type 2 diabetes. Three themes describing interactions related to diabetes self-management education accounted for about half of encounter content. The other half of encounter content was dedicated to interactions not explicitly related to diabetes described by 4 subthemes. In a successful CHW intervention, focused educational content was balanced with other interactions. Interactions not explicitly related to diabetes may have provided space for the implementation of core CHW roles, skills, and qualities other than educator, particularly those related to relationship building. It is important that interventions provide CHWs with sufficient time and flexibility to develop strong relationships with participants.

Community Health Workers as Trust Builders and Healers: A Cohort Study in Primary Care.

Improving patients' self-care for chronic disease is often elusive in the context of social deprivation. We evaluated whether a practice-integrated community health worker (CHW) intervention could encourage effective long-term self-management of type 2 diabetes mellitus (T2DM). This cohort study, in a safety-net primary care practice, enrolled patients with uncontrolled T2DM and psychosocial risk factors. Patients were identified through a practice diabetes registry or by clinicians' referrals. The CHWs engaged patients in trust building and sensemaking to understand their social context, identify goals, navigate health care, and connect to community resources. Primary outcome was progress through 3 prospectively defined stages of self-care: outreach (meeting face-to-face); stabilization (collaborating to address patients' life circumstances); and self-care generativity (achieving self-care competencies). Secondary outcomes were change in hemoglobin A1c (HbA1c) and need for urgent care, emergency department, or hospital visits. Of 986 participating patients, 27% remained in outreach, 41% progressed to stabilization, and 33% achieved self-care generativity. Repeated measures ANOVA demonstrates an overall decline in HbA1c, without group differences, through the 4th HbA1c measurement (mean follow-up 703 days). Beginning at the 5th HbA1c measurement (mean 859 days), the self-care generativity group achieved greater declines in HbA1c, which widened through the 10th measurement (mean 1,365 days) to an average of 8.5% compared with an average of 8.8% in the outreach group and 9.0% in the stabilization group (P = .003). Rates of emergency department and hospital visits were lower in the self-care generativity group. Practice-linked CHWs can sustainably engage vulnerable patients, helping them advance self-management goals in the context of formidable social disadvantage.

Evaluation of Community Health Worker Intervention in San Antonio

<h3>ABSTRACT</h3> <h3>Background</h3> The Neck Disability Index (NDI) is a 10-item questionnaire about symptoms relevant to cervical spine pathology, originally validated in the physical therapy literature. It is unclear if all of the items apply to spine surgery. The purpose of this study was to determine if improvements in the composite NDI score or specific NDI domains are appropriate measures for tracking changes in physical function after surgical intervention for cervical spondylotic myelopathy (CSM). <h3>Methods</h3> A retrospective cohort review of patients treated at a major academic medical center was undertaken. Baseline and postoperative standardized outcome measurement scores, including composite NDI, NDI subdomain, and SF-12 physical component score (PCS), were collected. Wilcoxon signed-rank test was used to determine whether patients exhibited improvement in each of the outcome measures included. Multiple linear regression was performed to determine whether change in NDI composite or subdomain scores predicted change in physical function after surgery for CSM—compared with the well-validated PCS score—controlling for factors such as age, sex, etc. <h3>Results</h3> Baseline data were collected on 118 patients. All outcome measures exhibited significant improvement after surgery based on the Wilcoxon signed-rank test. On linear regression, work (β = −2.419 [−3.831, −1.006]; <i>P</i> = .001) and recreation (β = −1.354 [−2.640, −0.068]; <i>P</i> = .039), as well as the NDI composite score (β = −0.223 [−0.319, −0.127]; <i>P</i> &lt; .001), were significant predictors of change in physical function over time. <h3>Conclusions</h3> Although the NDI composite score did predict change in PCS over time, only 2 of the 10 NDI subdomains were found to be associated with change in physical function over time. Based on these results, the item bank and composite scoring of the NDI are inappropriate for evaluating quality of life in studies of surgically treated cervical spondylotic myelopathy patients. <h3>Clinical Relevance</h3> NDI may not be a valid tool in the determination of physical function changes after surgery for CSM. <h3>Level of Evidence</h3> III.

Impact of community health worker intervention on PrEP knowledge and use in Rakai, Uganda: A mixed methods, implementation science evaluation.

Effective models of support for HIV pre-exposure prophylaxis (PrEP) are needed for populations at elevated risk. In a hyperendemic Ugandan fishing community, PrEP counseling was provided through a situated Information, Motivation, and Behavioral Skills (sIMB)-based community health worker (CHW) intervention. We evaluated the intervention using a mixed-methods, implementation science design. We surveyed all community members aged 15-49 through the Rakai Community Cohort Study. We used multivariable logistic regressions with generalized estimating equations to estimate the intervention's effect on PrEP knowledge and utilization. To understand intervention experiences and mechanisms, we conducted 74 qualitative interviews with 5 informant types (clients, CHWs, program staff, community leaders, health clinic staff) and analyzed data using an iterative, deductive approach. A mobile phone application provided intervention process implementation data. Individuals self-reporting receipt of the CHW intervention showed significantly higher PrEP knowledge (N = 1848, PRR: 1.10, 95% CI: 1.06-1.14, p = <.0001), PrEP ever use (N = 1176, PRR: 1.77, 95% CI: 1.33-2.36, p = <.0001), and PrEP current use (N = 1176, PRR: 1.86, 95% CI: 1.22-2.82, p = 0.0039) compared to those who did not. Qualitative findings attributed positive PrEP outcomes to CHW counseling and effective use of motivational interviewing skills by CHWs. Salient themes across the RE-AIM framework included support for the CHW intervention and PrEP across clients, community, and implementers. Mobile application data demonstrated consistent delivery of the PrEP module throughout implementation. CHWs improved PrEP knowledge and use among clients in an HIV hyperendemic fishing community. Mixed-methods, implementation science evaluations can inform adaptation of similar PrEP implementation strategies.

Oral community health worker-led interventions in households with average levels of psychosocial factors.

IntroductionHousehold-level psychosocial stress levels have been linked to child tooth brushing behaviors. Community health worker (CHW) interventions that target psychosocial factors in high-risk communities have been associated with changes in health behaviors.AimObserve changes in psychosocial factors over time and an association between psychosocial factors and CHW intervention dose amongst urban Chicago families.Patients and methodsParticipants (N = 420 families) were recruited from 10 community clinics and 10 Women, Infants, or Children (WIC) centers in Cook County, Illinois to participate in a clinical trial. Research staff collected participant-reported psychosocial factors (family functioning and caregiver reports of depression, anxiety, support, and social functioning) and characteristics of CHW-led oral health intervention visits (number, content, child engagement) at 0, 6, and 12 months. CHWs recorded field observations after home visits on household environment, social circumstances, stressors, and supports.ResultsParticipants across the cohort reported levels of psychosocial factors consistent with average levels for the general population for nearly all measures. Psychosocial factors did not vary over time. Social functioning was the only measure reported at low levels [32.0 (6.9); 32.1 (6.7); 32.7 (6.9); mean = 50 (standard deviation)] at 0, 6, and 12 months. We did not observe a meaningful difference in social functioning scores over time by exposure to CHW-led intervention visits (control arm, 0, 1, 2, 3, and 4 visits). Field observations made by CHWs described a range of psychosocial stress related to poverty, language barriers, and immigration status.ConclusionThe unexpectedly average and unchanging psychosocial factors over time, in the context of field observations of stress related to poverty, lack of support, immigration status, and language barriers, suggests that our study did not adequately capture the social determinants of health related to oral health behaviors or that measurement biases precluded accurate assessment. Future studies will assess psychosocial factors using a variety of instruments in an attempt to better measure psychosocial factors including social support, depression, anxiety, functioning, trauma and resilience within our urban population. We will also look at neighborhood-level factors of community distress and resilience to better apply the social ecologic model to child oral health behaviors.

Protocol and baseline characteristics for a community health worker-led hypertension and diabetes management program for South Asians in Atlanta: The DREAM Atlanta study

BackgroundSouth Asians are disproportionately affected by type 2 diabetes (DMII) and comorbid hypertension (HTN). Community health worker (CHW) interventions have been shown to improve chronic disease outcomes, yet few have been tailored for South Asians. This paper describes the study protocol and baseline characteristics of an evidence-based CHW intervention to improve blood pressure (BP) control among South Asian adults with diabetes and comorbid HTN in Atlanta, GA. MethodsA total of 195 South Asian adults were randomized to treatment and control groups, and of these 190 completed baseline surveys (97 treatment group and 93 control group). The treatment group receives five group education sessions on DMII and HTN management and two one-on-one goal setting sessions. MeasuresPrimary outcomes include feasibility, acceptability, and BP control (systolic blood pressure [SBP] <130 and diastolic blood pressure [DBP] <80). Secondary outcomes included changes in glycated hemoglobin (HbA1c), weight, diabetes self-efficacy, diet, and physical activity. Baseline resultsOf the enrolled sample, 56% are female and mean age is 56.0 (±11.7). All participants are foreign-born. Mean SBP was 139.2 ± 4.3 and mean DBP was 84.7 ± 9.5. Intervention outcomes are measured at baseline and 6-month endpoint for both study groups. ConclusionsTo our knowledge, this study is the first to document the efficacy of a HTN and DMII management intervention among South Asian adults in Atlanta, GA. Future findings of the submitted protocol will fill an important gap on the translation and adaption of evidence-based interventions that have relevance to immigrant and minority populations.Clinical trials registration: NCT04263311

Factors impacting sustainability of community health worker programming in rural Uganda: a qualitative study.

Despite significant global progress towards decreased child mortality in past decades, maternal and child mortality continues to be high, especially in sub Saharan Africa. Most of these deaths are preventable with known interventions. Community health workers (CHWs) are well-positioned to promote these life-saving interventions; however, sustaining CHW programs remains a challenge. A sustainability-focused qualitative evaluation, was done between July and August 2018 in 2 rural districts in southwest Uganda. Using semi-structured interview tools, we conducted 6 Focus Group discussions (FGDs) with CHWs and 17 in-depth interviews (IDIs) with various district stakeholders to gain insights into factors affecting sustainability of a district-wide maternal, newborn and child health (MNCH)-oriented CHW intervention. Data was managed using NVivo software (version 12) with themes using thematic analysis. Identified factors impacting CHW program sustainability included 'health system effectiveness' (availability of supplies, medicines and services and availability of facility health providers), CHW program-related factors' (CHW selection and training, CHW recognition), 'community attitudes and beliefs' and 'stakeholder engagement'. To sustain CHW programs in rural Uganda and globally, planners, policymakers and funders should maximize community engagement in establishing CHW networks and strengthen accountability, supply chains and linkages with communities and health facilities.
