BACKGROUND:Despite the proven efficacy of evidence-based healthcare interventions in reducing adverse outcomes and mortality associated with Sickle Cell Disease (SCD), a vast majority of affected individuals in Africa remain deprived of such care. Hydroxyurea (HU) utilization among SCD patients in Sub-Saharan Africa (SSA) stands at less than 1%, while in Nigeria, approximately 13% of patients benefit from HU therapy. To enhance HU utilization, targeted implementation strategies addressing provider-level barriers are imperative. Existing evidence underscores the significance of addressing barriers such as inadequate healthcare worker training to improve HU adoption. The ACCELERATE study aims to evaluate the adoption of HU among providers through the Screen, Initiate, and Maintain (SIM) intervention, facilitated by healthcare worker training, clinical reminders, and task-sharing strategies, thereby enhancing patient-level SCD management in Nigeria. METHODS:This study will implement the SIM intervention, encompassing patient screening, initiation of HU treatment, and maintenance of dosage, which will be implemented via the TAsk-Strengthening Strategy for Hemoglobinopathies (TASSH TCP), derived from our team's TAsk-Strengthening Strategy for Hypertension control (TASSH) trials. Employing a sequential exploratory mixed-methods approach within the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework, this study will assess SIM adoption by providers in Nigeria. The primary outcome is the rate of SIM adoption at clinical sites at 12 months, with secondary outcomes including sustainability/maintenance of SIM intervention and implementation fidelity. DISCUSSION/CONCLUSIONS:This study's findings will offer crucial insights into effective SCD management strategies, leveraging existing SCD clinical networks and resources in Nigeria to enhance HU adoption among providers in a scalable and sustainable manner. Additionally, the study will inform best practices for implementing HU therapy in resource-constrained settings, benefiting healthcare providers, policymakers, and stakeholders invested in improving SCD care delivery.

BACKGROUND/UNASSIGNED:Evidence-based interventions (EBI) for cardiovascular disease (CVD) in low- and middle-income countries (LMIC) may face feasibility challenges due to the inadequacy of existing instruments. To address this, researchers developed the Contextual Index of Feasibility on Early-Stage Implementation in LMIC (CATALYTIC) tool, which integrates contextual factors into the assessment of feasibility. METHODS/UNASSIGNED:The tool's items were developed through a systematic review and key informant interviews, and were later assessed for relevance and importance by 13 LMIC researchers and implementers employing a Delphi technique. The survey was then tested for usability by five individuals with CVD experience in LMIC. The CATALYTIC tool consists of 17 items that measure contextual factors that directly influence early-stage LMIC implementation. Descriptive analysis, logistic regression, item reliability using Cronbach's alpha, and exploratory factor analysis (EFA) were performed on survey data. RESULTS/UNASSIGNED:In a survey of 216 respondents from 46 countries, 63.4 to 81.5% of respondents noted a significant impact of contextual factors on implementation feasibility, with high reliability (Cronbach's alpha 0.88) for 12 items. The majority of interventions focused on patient-level care in rural settings. The survey items align primarily with constructs related to implementation climate and readiness for implementation, as well as inductive themes addressing existing needs and barriers to inform intervention design. The survey found diversity in geographic and experiential backgrounds, with significant representation from South Africa, Mexico, and India. Over a third identified as researchers, and 15% held multiple roles. The survey identified three distinct factors influencing how researchers and implementers assess CVD intervention feasibility in LMIC. A 6% increase in odds for moderately feasible interventions was linked to each point increase in the composite score of perceived contextual influence. CONCLUSION/UNASSIGNED:Overall, the CATALYTIC tool with 12 reliable survey items can help researchers and implementers elucidate perceptions of contextual factors influencing the feasibility of CVD-related EBI in LMIC. The survey items reflect respondents' practical focus in resource-limited settings and can inform intervention design by addressing existing needs and barriers. The tool's integration of contextual factors into the assessment of feasibility can help overcome the inadequacy of existing instruments by providing more tailored and conceptually clear assessments of feasibility.

As people living with HIV experience increased life expectancy, there is a growing concern about the burden of comorbid non-communicable diseases, particularly hypertension. This brief describes the current policy landscape on the management of HIV and hypertension in Akwa Ibom State, Nigeria, stakeholder engagement meetings, and the resulting five policy recommendations rooted in an ongoing research study designed to integrate hypertension management into HIV care across primary health centers in the State. In order to identify the current gaps in integrated care, discussion sessions with three stakeholder groups (i.e., healthcare providers, patient advocacy groups, and policy makers) were held separately in November 2022. The discussions were purposed to brainstorm policy-level solutions for integrating hypertension into HIV treatment. After all the sessions were concluded, there were five recommendations provided by the stakeholders for integrating HIV and hypertension care in the Akwa Ibom State. Stakeholders unanimously agreed with the need to integrate hypertension care for HIV impacted communities in the State. Specifically, stakeholders recommended to: (1) engage retired community health nurses as mentors; (2) actively link communities to integrated care in clinics; (3) integrate hypertension management with HIV education; (4) expand health insurance accessibility; and (5) formally integrate hypertension management into primary healthcare centers in Akwa Ibom State.

IMPORTANCE/UNASSIGNED:Black and Hispanic patients have high rates of recurrent stroke and uncontrolled hypertension in the US. The effectiveness of home blood pressure telemonitoring (HBPTM) and telephonic nurse case management (NCM) among low-income Black and Hispanic patients with stroke is unknown. OBJECTIVE/UNASSIGNED:To determine whether NCM plus HBPTM results in greater systolic blood pressure (SBP) reduction at 12 months and lower rate of stroke recurrence at 24 months than HBPTM alone among Black and Hispanic stroke survivors with uncontrolled hypertension. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:Practice-based, multicenter, randomized clinical trial in 8 stroke centers and ambulatory practices in New York City. Black and Hispanic study participants were enrolled between April 18, 2014, and December 19, 2017, with a final follow-up visit on December 31, 2019. INTERVENTIONS/UNASSIGNED:Participants were randomly assigned to receive either HBPTM alone (12 home BP measurements/week for 12 months, with results transmitted to a clinician; n = 226) or NCM plus HBPTM (20 counseling calls over 12 months; n = 224). MAIN OUTCOMES AND MEASURES/UNASSIGNED:Primary outcomes were change in SBP at 12 months and rate of recurrent stroke at 24 months. Final statistical analyses were completed March 14, 2024. RESULTS/UNASSIGNED:Among 450 participants who were enrolled and randomized (mean [SD] age, 61.7 [11.0] years; 51% were Black [n = 231]; 44% were women [n = 200]; 31% had ≥3 comorbid conditions [n = 137]; 72% had household income <$25 000/y [n = 234/324]), 358 (80%) completed the trial. Those in the NCM plus HBPTM group had a significantly greater SBP reduction than those in the HBPTM alone group at 12 months (-15.1 mm Hg [95% CI, -17.2 to -13.0] vs -5.8 mm Hg [95% CI, -7.9 to -3.7], respectively; P < .001). The between-group difference in SBP reduction at 12 months, adjusted for primary care physician clustering, was -8.1 mm Hg (95% CI, -11.2 to -5.0; P < .001) at 12 months. The rate of recurrent stroke was similar between both groups at 24 months (4.0% in the NCM plus HBPTM group vs 4.0% in the HBPTM alone group, P > .99). CONCLUSIONS AND RELEVANCE/UNASSIGNED:Among predominantly low-income Black and Hispanic stroke survivors with uncontrolled hypertension, addition of NCM to HBPTM led to greater SBP reduction than HBPTM alone. Additional studies are needed to understand the long-term clinical outcomes, cost-effectiveness, and generalizability of NCM-enhanced telehealth programs among low-income Black and Hispanic stroke survivors with significant comorbidity.

The COVID-19 pandemic placed a spotlight on the potential to dramatically increase the use of telehealth across the cancer care continuum, but whether and how telehealth can be implemented in practice in ways that reduce, rather than exacerbate, inequities are largely unknown. To help fill this critical gap in research and practice, we developed the Framework for Integrating Telehealth Equitably (FITE), a process and evaluation model designed to help guide equitable integration of telehealth into practice. In this manuscript, we present FITE and showcase how investigators across the National Cancer Institute's Telehealth Research Centers of Excellence are applying the framework in different ways to advance digital and health equity. By highlighting multilevel determinants of digital equity that span further than access alone, FITE highlights the complex and differential ways structural determinants restrict or enable digital equity at the individual and community level. As such, achieving digital equity will require strategies designed to not only support individual behavior but also change the broader context to ensure all patients and communities have the choice, opportunity, and resources to use telehealth across the cancer care continuum.

BACKGROUND:Stroke is a major public health problem, with the disabilities of the patients increasing their risk of poor oral health. Currently, in Ghana and Nigeria, no guideline exists for oral health care in stroke patients, while most of our acute stroke care settings have no documented protocol. AIM/OBJECTIVE:This study sought to understand the perspectives of healthcare professionals in Ghana and Nigeria about oral healthcare in acute stroke patients. METHODS:A qualitative inductive approach was employed to explore healthcare professionals' perspectives. After obtaining informed consent, in-depth interviews were conducted among doctors, nurses, and physiotherapists using semi-structured question guides. Participants' responses were audiotaped for transcription and analysis. Interviews were conducted until data saturation was reached. Data were analyzed thematically to generate themes and sub-themes using an inductive approach. THE RESULTS/RESULTS:Twenty-five (25) health care professionals (HCP) aged 25-60 years with a mean age of 36.2 ± 4.2 years were interviewed. There were 15 (60.0%) males and 10 (40.0%) females. HCP included nurse practitioners 14 (56.0%), medical doctors 7 (28.0%), and physiotherapists 4 (16.0%). The HCP demonstrated adequate knowledge of stroke and considered oral health important for esthetic and clinical reasons. They, however, reported being unable to give it the required attention due to inadequate collaboration between the various professional cadres, insufficient equipment, and a skewed focus on other clinical needs of the acute stroke patients. CONCLUSIONS:The findings indicate that HCPs perceived oral health care as very important among patients with acute stroke. However, they reported a lack of collaboration and integration of oral health care in routine stroke care as a major impediment.

BACKGROUND/UNASSIGNED:As people living with HIV experience increased life expectancy, there is a growing concern about the burden of comorbid non-communicable diseases, particularly hypertension. This policy brief describes the current policy landscape in Akwa Ibom State, Nigeria, the research activities, and five policy recommendations rooted in an ongoing research study designed to integrate hypertension management into HIV care across primary health centers in the state. ANALYSIS/UNASSIGNED:The policy brief was developed in four steps: review of existing policies, using the reviewed policies to inform research activities, solicitation of stakeholder recommendations via focus group discussions, and formulation of the resulting five policy recommendations for integrating hypertension management into HIV care programs in Akwa Ibom. The key analysis for this brief emerged from the thematic analyses of stakeholder responses. POLICY IMPLICATIONS/UNASSIGNED:The five policy recommendations for integrating hypertension management in HIV care in Akwa Ibom State, Nigeria are: 1) build capacity by leveraging retired community nurses as mentors; 2) emphasize community engagement; 3) develop consistent training programs on hypertension management for health workers; 4) expand health insurance accessibility; and 5) formally integrate hypertension management into primary healthcare centers in Akwa Ibom State.

BACKGROUND/UNASSIGNED:This study aimed to quantify the association between childhood family environment and longitudinal cardiovascular health (CVH) in adult CARDIA (Coronary Artery Risk Development in Young Adults) Study participants. We further investigated whether the association differs by adult income. METHODS/UNASSIGNED:We applied the CVH framework from the American Heart Association including metrics for smoking, cholesterol, blood pressure, glucose, body mass index, physical activity, and diet. CVH scores (range, 0-14) were calculated at years 0, 7, and 20 of the study. Risky Family environment (range, 7-28) was assessed at year 15 retrospectively, for childhood experiences of abuse, caregiver warmth, and family or household challenges. Complete case ordinal logistic regression and mixed models associated risky family (exposure) with CVH (outcome), adjusting for age, sex, race, and alcohol use. RESULTS/UNASSIGNED:The sample (n=2074) had a mean age of 25.3 (±3.5) years and 56% females at baseline. The median risky family was 10 with ideal CVH (≥12) met by 288 individuals at baseline (28.4%) and 165 (16.3%) at year 20. Longitudinally, for every 1-unit greater risky family, the odds of attaining high CVH (≥10) decreased by 3.6% (OR, 0.9645 [95% CI, 0.94-0.98]). Each unit greater child abuse and caregiver warmth score corresponded to 12.8% lower and 11.7% higher odds of ideal CVH (≥10), respectively (OR, 0.872 [95% CI, 0.77-0.99]; OR, 1.1165 [95% CI, 1.01-1.24]), across all 20 years of follow-up. Stratified analyses by income in adulthood demonstrated associations between risky family environment and CVH remained significant for those of the highest adult income (>$74k), but not the lowest (<$35k). CONCLUSIONS/UNASSIGNED:Although risky family environmental factors in childhood increase the odds of poor longitudinal adult CVH, caregiver warmth may increase the odds of CVH, and socioeconomic attainment in adulthood may contextualize the level of risk. Toward a paradigm of primordial prevention of cardiovascular disease, childhood exposures and economic opportunity may play a crucial role in CVH across the life course.

BACKGROUND:Access to antiretroviral therapy has increased life expectancy and survival among people living with HIV (PLWH) in African countries like Nigeria. Unfortunately, non-communicable diseases such as cardiovascular diseases are on the rise as important drivers of morbidity and mortality rates among this group. The aim of this study was to explore the perspectives of key stakeholders in Nigeria on the integration of evidence-based task-sharing strategies for hypertension care (TASSH) within existing HIV clinics in Nigeria. METHODS:Stakeholders representing PLWH, patient advocates, health care professionals (i.e. community health nurses, physicians and chief medical officers), as well as policymakers, completed in-depth qualitative interviews. Stakeholders were asked to discuss facilitators and barriers likely to influence the integration of TASSH within HIV clinics in Akwa Ibom, Nigeria. The interviews were transcribed, keywords and phrases were coded using the PEN-3 cultural model as a guide. Framework thematic analysis guided by the PEN-3 cultural model was used to identify emergent themes. RESULTS:Twenty-four stakeholders participated in the interviews. Analysis of the transcribed data using the PEN-3 cultural model as a guide yielded three emergent themes as assets for the integration of TASSH in existing HIV clinics. The themes identified are: 1) extending continuity of care among PLWH; 2) empowering health care professionals and 3) enhancing existing workflow, staff motivation, and stakeholder advocacy to strengthen the capacity of HIV clinics to integrate TASSH. CONCLUSION/CONCLUSIONS:These findings advance the field by providing key stakeholders with knowledge of assets within HIV clinics that can be harnessed to enhance the integration of TASSH for PLWH in Nigeria. Future studies should evaluate the effect of these assets on the implementation of TASSH within HIV clinics as well as their effect on patient-level outcomes over time.
