Background Child tuberculosis (TB) contact management is recommended for preventing TB in children but its implementation is suboptimal in high TB/HIV-burden settings. The PREVENT Study was a mixed-methods, clustered-randomized implementation study that evaluated the effectiveness and acceptability of a community-based intervention (CBI) to improve child TB contact management in Lesotho, a high TB burden country. Methods Ten health facilities were randomized to CBI or standard of care (SOC). CBI holistically addressed the complex provider-, patient-, and caregiver-related barriers to prevention of childhood TB. Routine TB program data were abstracted from TB registers and cards for all adult TB patients aged >18 years registered during the study period, and their child contacts. Primary outcome was yield (number) of child contacts identified and screened per adult TB patient. Generalized linear mixed models tested for differences between study arms. CBI acceptability was assessed via semi-structured in-depth interviews with a purposively selected sample of 20 healthcare providers and 28 caregivers. Qualitative data were used to explain and confirm quantitative results. We used thematic analysis to analyze the data. Results From 01/2017-06/2018, 973 adult TB patients were recorded, 490 at CBI and 483 at SOC health facilities; 64% male, 68% HIV-positive. At CBI and SOC health facilities, 216 and 164 child contacts were identified, respectively (p = 0.16). Screening proportions (94% vs. 62%, p = 0.13) were similar; contact yield per TB case (0.40 vs. 0.20, p = 0.08) was higher at CBI than SOC health facilities, respectively. CBI was acceptable to caregivers and healthcare providers. Conclusion Identification and screening for TB child contacts were similar across study arms but yield was marginally higher at CBI compared with SOC health facilities. CBI scale-up may enhance the ability to reach and engage child TB contacts, contributing to efforts to improve TB prevention among children.

Abstract Background There are major gaps in the management of pediatric tuberculosis (TB) contact investigation for rapid identification of active tuberculosis and initiation of preventive therapy. This study aims to evaluate the impact of a community-based intervention as compared to facility-based model for the management of children in contact with bacteriologically confirmed pulmonary TB adults in low-resource high-burden settings. Methods/design This multicenter parallel open-label cluster randomized controlled trial is composed of three phases: I, baseline phase in which retrospective data are collected, quality of data recording in facility registers is checked, and expected acceptability and feasibility of the intervention is assessed; II, intervention phase with enrolment of index cases and contact cases in either facility- or community-based models; and III, explanatory phase including endpoint data analysis, cost-effectiveness analysis, and post-intervention acceptability assessment by healthcare providers and beneficiaries. The study uses both quantitative and qualitative analysis methods. The community-based intervention includes identification and screening of all household contacts, referral of contacts with TB-suggestive symptoms to the facility for investigation, and household initiation of preventive therapy with follow-up of eligible child contacts by community healthcare workers, i.e., all young (< 5 years) child contacts or older (5–14 years) child contacts living with HIV, and with no evidence of TB disease. Twenty clusters representing TB diagnostic and treatment facilities with their catchment areas are randomized in a 1:1 ratio to either the community-based intervention arm or the facility-based standard of care arm in Cameroon and Uganda. Randomization was stratified by country and constrained on the number of index cases per cluster. The primary endpoint is the proportion of eligible child contacts who initiate and complete the preventive therapy. The sample size is of 1500 child contacts to identify a 10% difference between the arms with the assumption that 60% of children will complete the preventive therapy in the standard of care arm. Discussion This study will provide evidence of the impact of a community-based intervention on household child contact screening and management of TB preventive therapy in order to improve care and prevention of childhood TB in low-resource high-burden settings.

Background The COVID-19 pandemic has brought many health systems in low resource settings to their knees. The pandemic has had crippling effects on the already strained health systems in provision of maternal and newborn healthcare. With the travel restrictions, social distancing associated with the containment of theCOVID-19 pandemic, healthcare providers could be faced with challenges of accessing their work stations, and risked burnout as they offered maternal and newborn services. This study sought to understand the experiences and perceptions of healthcare providers at the frontline during the first phase of the lockdown as they offered maternal and newborn health care services in both public and private health facilities in Uganda with the aim of streamlining patient care in face of the current COVID-19 pandemic and in future disasters. Methods Between June 2020 and December 2020, 25 in-depth interviews were conducted among healthcare providers of different cadres in eight Public, Private-Not-for Profit and Private Health facilities in Kampala, Uganda. The interview guide primarily explored the lived experiences of healthcare providers as they offered maternal and newborn healthcare services during the COVID-19 pandemic. All of the in depth interviews were audio recorded and transcribed verbatim. Themes and subthemes were identified using both inductive thematic and phenomenological approaches. Results The content analysis of the in depth interviews revealed that the facilitators of maternal and newborn care service delivery among the healthcare providers during the COVID-19 pandemic included; salary bonuses, the passion to serve their patients, availability of accommodation during the pandemic, transportation to and from the health facilities by the health facilities, teamwork, fear of losing their jobs and fear of litigation if something went wrong with the mothers or their babies. The barriers to their service delivery included; lack of transport means to access their work stations, fear of contracting COVID-19 and transmitting it to their family members, salary cuts, loss of jobs especially in the private health facilities, closure of the non-essential services to combat high patient numbers, inadequate supply of Personal Protective equipment (PPE), being put in isolation or quarantine for two weeks which meant no earning, brutality from the security personnel during curfew hours and burnout from long hours of work and high patient turnovers. Conclusion The COVID-19 Pandemic has led to a decline in quality of maternal and newborn service delivery by the healthcare providers as evidenced by shorter consultation time and failure to keep appointments to attend to patients. Challenges with transport, fears of losing jobs and fear of contracting COVID-19 with the limited access to personal protective equipment affected majority of the participants. The healthcare providers in Uganda despite the limitations imposed by the COVID-19 pandemic are driven by the inherent passion to serve their patients. Availability of accommodation and transport at the health facilities, provision of PPE, bonuses and inter professional teamwork are critical motivators that needed to be tapped to drive teams during the current and future pandemics.

Abstract Background The expanding roles and increasing importance of the nursing workforce in health services delivery in resource-limited settings is not adequately documented and sufficiently recognized in the current literature. Drawing upon the theme of 2020 as the international year of the nurse and midwife, we set out to describe how the role of nurses had expanded tremendously in health facilities in Uganda during the era of anti-retroviral therapy (ART) scale-up between 2004 and 2014.Methods A mixed-methods study was conducted in two phases. Phase One entailed a cross-sectional health facility survey (n=195) to assess the extent to which human resource management strategies (such as task shifting) were common. Phase Two entailed qualitative case-studies of 16 (of the 195) health facilities for an in-depth understanding of the strategies adopted (e.g. nurse-centred HIV care). We adopted a qualitatively-led mixed methods approach whereby core thematic analyses were supported by descriptive statistics.Results We found that nurses were the most represented cadre of health workers involved in the overall leadership of HIV clinics across Uganda. Most of nurse-led HIV clinics were based in rural settings although this trend was fairly even across all settings (rural/urban/peri-urban). A number of health facilities in our sample (n=36) deliberately adopted nurse-led HIV care models. Nurses were empowered to be multi-skilled with a wide range of competencies across the HIV care continuum right from HIV testing to mainstream clinical HIV disease management. In several facilities, nursing cadre were the backbone of ART service delivery. A select number of facilities devised differentiated models of task shifting from physicians to doctors to nurses in which the latter handled patients who were stable on ART.Conclusion Overall, our study reveals a wide expansion in the scope-of-practice of nurses during the initial ART scale-up phase in Uganda. Nurses were thrust in roles of HIV disease management that were traditionally the preserve of medical doctors. Our study underscores the importance of reforming regulatory frameworks governing nursing workforce scope of practice in Uganda such as the need for evolving a policy on task shifting which is currently lacking in Uganda.

Abstract Background: There is a need for evaluating community-based antiretroviral therapy (ART) delivery models to improve overall performance of HIV programs, specifically in populations that may have difficulties to access continuous care. This cluster-randomized clinical trial aims to evaluate the efficacy of a multicomponent differentiated ART delivery model (VIBRA model) after home-based same-day ART initiation in remote villages in Lesotho, Southern Africa. Methods: VIBRA (Village-Based Refill of ART) trial is a cluster-randomized, parallel-group, superiority clinical trial conducted in two districts of Lesotho, Southern Africa. Clusters (i.e. villages) are randomly assigned to either the VIBRA model or standard of care, stratified by district, village size, and village access to the nearest health facility. Eligible individuals (HIV-positive, aged 10 years or older, not taking ART) found during community-based HIV testing campaigns are offered same-day home-based ART initiation. Intervention clusters offer a differentiated ART delivery package with two features: Firstly, drug-refill and follow-up through trained and supervised village health workers. Secondly, the option of receiving individually tailored adherence reminders and viral load result notifications via SMS. Standard of care applies for the control clusters, i.e. ART visits at the clinic and no SMS. The primary endpoint is viral suppression 12 months after enrolment. Secondary endpoints include linkage to and engagement in care. Furthermore, safety and cost-effectiveness analyses plus qualitative research are planned. Minimum target sample size is 262 participants. Statistical analyses will follow CONSORT guidelines. VIBRA trial is linked to another trial, the HOSENG (HOme-based SElf-testiNG) trial, in the GET ON (GETing tOwards Ninety) research project. Discussion: VIBRA trial is among the first to evaluate ART delivery through VHW immediately after ART-initiation and it assesses the entire HIV care cascade from testing to viral suppression. As most countries in sub-Saharan Africa have cadres similar to the VHW program in Lesotho, this model – if shown to be effective – has potential to be scaled up. The system impact evaluation will provide valuable cost estimations, and the qualitative research will suggest how the model could further be modified to optimize impact. Trial Registration: This trial has been registered at clinicaltrials.gov (NCT03630549) on August 15, 2018. Keywords: HIV, cluster randomized controlled trial, village health worker, community health worker, home-based, differentiated care and delivery, antiretroviral therapy, Lesotho, Southern Africa, multi component intervention.

Abstract Background Following the World Health Organization’s (WHO) 2015 guidelines recommending initiation of antiretroviral therapy (ART) irrespective of CD4 count for all people living with HIV (PLHIV), many countries in sub-Saharan Africa have adopted this strategy to reach epidemic control. As the number of PLHIV on ART rises, maintenance of viral suppression on ART for over 90% of PLHIV remains a challenge to government health systems in resource-limited high HIV burden settings. Non facility-based antiretroviral therapy (ART) delivery for stable HIV+ patients may increase sustainable ART coverage in resource-limited settings. Within the HPTN 071 (PopART) trial, two models, home-based delivery (HBD) or adherence clubs (AC), were offered to assess whether they achieved similar viral load suppression (VLS) to standard of care (SoC). In this paper, we describe the trial design and discuss the methodological issues and challenges. Methods A three-arm cluster randomized non-inferiority trial, nested in two urban HPTN 071 trial communities in Zambia, randomly allocated 104 zones to SoC (35), HBD (35), or AC (34). ART and adherence support were delivered 3-monthly at home (HBD), adherence clubs (AC), or clinic (SoC). Adult HIV+ patients defined as “stable” on ART were eligible for inclusion. The primary endpoint was the proportion of PLHIV with virological suppression (≤ 1000 copies HIV RNA/ml) at 12 months (± 3months) after study entry across all three arms. Viral load measurement was done at the routine government laboratories in accordance with national guidelines, annually. The study was powered to determine if either of the community-based interventions would yield a viral suppression rate drop compared to SoC of no more than 5% in its absolute value. Both community-based interventions were delivered by community HIV providers (CHiPs). An additional qualitative study using observations, interviews with PLHIV, and FGDs with community HIV providers was nested in this study to complement the quantitative data. Discussion This trial was designed to provide rigorous randomized evidence of safety and efficacy of non-facility-based delivery of ART for stable PLHIV in high-burden resource-limited settings. This trial will inform policy regarding best practices and what is needed to strengthen scale-up of differentiated models of ART delivery in resource-limited settings.

AbstractObjectivesTo explore how sociocultural factors may support or impede the adoption of community-based distribution of injectable contraceptives in Nigeria.DesignA qualitative study based on a grounded theory approach was conducted through in-depth interviews and focus group discussions.SettingMost participants lived in Gombe State, North East Nigeria. Other participants were from Ibadan (South West) and Abuja (Federal capital territory).ParticipantsThrough seven key informant interviews, 15 in-depth interviews and 10 focus group discussions, 102 participants were involved in the study.MethodsThis study, conducted in 2016 was part of a larger study on scale up of community-based distribution of injectable contraceptives. Qualitative data were collected from traditional and religious leaders, health workers and community members. The data were audio recorded, transcribed and analysed using a thematic framework method.ResultsSociocultural challenges to scale up included patriarchy and men’s fear of losing control over their spouses, traditional and religious beliefs about fertility, and myths about contraceptives and family planning. As a result of deep-rooted beliefs that children are ‘divine blessings’ and that procreation should not be regulated, participants described a subtle resistance to uptake of injectable contraceptives. Since Gombe is largely a patriarchal society, male involvement emerged as important to the success of meaningful innovation uptake. Community leaders largely described their participation in the scale up process as active, although they also identified scope for further involvement and recognition.ConclusionScale up is more than setting up health sector implementing structures, training health workers and getting innovation supplies, but also requires preparedness which includes paying attention to complex contextual issues. This requires the health system and those who work in it, to move beyond a narrow health ‘comfort zone’ by actively engaging with, and learning from, those who are leading, caring for and living in, the community.Strengths and limitations of this studyThe study participants represented a range of stakeholders - users of injectable contraceptives, community members, providers and health system managers.Our results highlighted that scale up is influenced by several socio-cultural factors; thus, showing the importance of paying attention to complex contextual issues during innovation uptake.The findings of our study emphasized how health systems and communities should interact in order to ensure successful scale up of health innovations.As with any qualitative study, the findings of this study are not statistically generalizable.FundingThis research was supported by the Consortium for Advanced Research Training in Africa (CARTA).
