BACKGROUND: In high-burden settings, most tuberculosis (TB) transmission likely occurs outside the home. Our qualitative study in Zambia explored the acceptability and preferences for designing TB active case finding (ACF) strategies to reach non-household contacts of people with TB. METHODS: We conducted 56 in-depth interviews with persons with TB ( RESULTS: All participants felt that TB was an important issue in their community and that new detection strategies were needed. A "social-network strategy" was perceived as acceptable and feasible, where participants noted it was a caring act and could facilitate early diagnosis. For a "venue-based strategy," most participants suspected TB transmission occurred at bars/taverns due to heavy alcohol use and prolonged time spent in crowded spaces; churches and betting halls were also commonly mentioned locations. Nearly all owners/leaders and patrons/attendees of bars, churches, and betting halls expressed acceptance of a venue-based strategy. They also indicated an interest in participating, citing many benefits, including increased TB knowledge/awareness, early diagnosis, convenience, and possibly reduced transmission, and recommended that the strategy incorporate sensitization, consent, volunteerism, and respectful, confidential, private services. For both strategies, most participants preferred the use of and being approached by trained peer TB survivors to facilitate ACF, given their prior TB patient experience and trust among community members. CONCLUSION: Stakeholders found social-network and venue-based TB-ACF strategies highly acceptable, recognizing their potential benefits for individuals and the broader community. Future research should evaluate the feasibility and effectiveness of TB ACF strategies for reaching non-household contacts.

INTRODUCTION: Hepatitis B virus (HBV) is highly infectious and deadly disease that is transmitted through blood and body fluids. Health care workers (HCWs) have a high risk of contracting HBV in health care settings, the Hep-B vaccine one of the recommended prevention intervention/tools. However, uptake of the vaccine among HCWs remains low in Sub-Saharan Africa. We aimed to explore the barriers and facilitators to uptake of the vaccine offered free of charge to HCWs and nursing students in Kalulushi district, Copperbelt Province of Zambia. METHODS: A total of 29 in-depth interviews (IDIs), either in person or via telephone, with participants before and after they received the vaccines were used to collect the data. We analysed the barriers and facilitators to full or partial vaccination using Penchasky and Thomas's (1981) 5A's (Access, Affordability, Awareness, Acceptance and Activation) taxonomy framework for vaccine hesitancy. RESULTS: All participants had access to the vaccine, and it was free of charge, making it affordable. Regarding awareness, all participants were aware of HBV infection as an occupational hazard, however, HCWs felt that more sensitization would be needed to increase awareness and knowledge of the vaccine. Acceptability of the vaccine was high among all completers and some non-completers as they felt it was safe and offered them protection. One non-completer felt coerced to accept the first dose due to supervisor expectations and would have preferred to have been given more time to decide. Most felt that vaccination should be compulsory for HCWs. Lastly, activation (vaccine uptake) among non-completers was hindered by late or no notification of appointments as the main reason for not completing the full vaccination schedule. HCWs advised that for countrywide roll-out, at least one weeks' notification would be necessary for HCWs to plan and be mentally prepared to be at their workstations when the vaccination is taking place. CONCLUSIONS: The need to offer the vaccine free of charge locally to ensure easy access and affordability is essential to increase vaccine uptake. Vaccination policies and guidelines for health workers, ongoing training and knowledge sharing are required. Involving trained champions in the facility can also help encourage HCWs to get vaccinated.

BACKGROUND: The novel COVID-19 pandemic threatened to disrupt access to human immunodeficiency (HIV) treatment for persons living with HIV (PLHIV), two-thirds of whom live in sub-Saharan Africa. To inform a health system response supportive of continuity of care, we sought to understand clients' HIV care experiences and health priorities during the first wave of COVID-19 outbreak in Lusaka, Zambia. METHODS: Leveraging a study cohort of those who completed periodic SMS surveys on HIV care, we purposefully sampled 25 PLHIV after first confirmed COVID-19 case was reported in Zambia on 18 RESULTS: All participants were aware of COVID-19, and HIV care experiences and health priorities of clients were affected by associated changes at health system, household, and individual level. The health system instituted early clinic visits to provide 6-months of antiretroviral therapy (ART) for stable patients and 3-months for unstable patients to reduce clinic visits and wait times. Most patients welcomed this long-desired extended appointment spacing. Some reported feeling respected and engaged when health care workers telephoned requesting their early clinic visit. However, others felt discouraged by an absence of physical distancing during their clinic visit due to 'severe acute respiratory syndrome coronavirus 2' (SARS-CoV-2) infection concerns. Several expressed a lack of clarity regarding next viral load monitoring date and means for receiving results. Patients suggested regular patient-facility communication by telephone and SMS. Patients emphasized that COVID-19 restrictions led to loss of employment and household income, exacerbating poverty and difficulties in taking ART. At individual level, most participants felt motivated to stay healthy during COVID-19 by ART adherence and regular laboratory monitoring. CONCLUSIONS: Clients' HIV care and health priorities during the first wave of COVID-19 in Lusaka province were varied with a combination of positive and negative experiences that occurred especially at health system and individual levels, while at household level, the experiences were all negative. More research is needed to understand how patients practice resiliency in the widespread context of socio-economic instability. Governments and patients must work together to find local, health systems solutions to support ART adherence and monitoring. Additionally, the health system should consider how to build on changes for long-term HIV management and service delivery.

INTRODUCTION: Poor client-provider communication is a critical barrier to long-term retention in care among people living with HIV. However, standardized assessments of this key metric are limited in Africa. We used the Roter Interaction Analysis System (RIAS) to quantitatively characterize patterns of person-centred communication (PCC) behaviours in Zambia. METHODS: We enrolled pairs of people living with HIV making routine HIV follow-up visit and their providers at 24 Ministry of Health-facilities supported by the Centre for Infectious Disease Research in Zambia in Lusaka province between August 2019 and November 2021. Client-provider encounters were audio-recorded and coded using RIAS by trained research staff. We performed latent class analysis to identify interactions with distinctive patterns of provider PCC behaviours (i.e. rapport building, person-centred counselling, PCC micropractices [e.g. brief empathy statements], assessing barriers to care, shared decision-making and leveraging discretionary power) and compared their distribution across client, provider, interaction and facility characteristics. RESULTS: We enrolled 478 people living with HIV and 139 providers (14% nurses, 73.6% clinical officers, 12.3% were medical officers). We identified four distinct profiles: (1) "Medically Oriented Interaction, Minimal PCC Behaviours" (47.6% of interactions) was characterized by medical discussion, minimal psychosocial/non-medical talk and low use of PCC behaviours; (2) "Balanced Medical/Non-medical Interaction, Low PCC Behaviours" (21.0%) was characterized by medical and non-medical discussion but limited use of other PCC behaviours; (3) "Medically Oriented Interaction, Good PCC Behaviours" (23.9%) was characterized by medically oriented discussion, more information-giving and increased use of PCC behaviours; and (4) "Highly person-centred Interaction" (7.5%) was characterized by both balanced medical/non-medical focus and the highest use of PCC behaviours. Nurse interactions were more likely to be characterized by more PCC behaviours (i.e. Class 3 or 4) (44.8%), followed by medical officers (33.9%) and clinical officers (27.3%) (p = 0.031). Longer interactions were also more likely to integrate more PCC behaviours (p < 0.001). CONCLUSIONS: PCC behaviours are relatively uncommon in HIV care in Zambia, and often limited to brief rapport-building statements and PCC micropractices. Strengthening PCC, such as shared decision-making and leveraging discretionary power to better accommodate client needs and preferences, may be an important strategy for improving the quality in HIV treatment programmes.
"Provider discretionary power practices to support implementation of patient-centered HIV care in Lusaka, Zambia".
(2022) Mwamba C; Mukamba N; Sharma A; Lumbo K; Foloko M; Nyirenda H; Simbeza S; Sikombe K; Holmes CB; Sikazwe I; Moore CB; Mody A; Geng E; Beres LK; Department of International Health, Johns Hopkins Bloomberg School of Public Health, Baltimore, MD, United States.; Department of Public Health Environments and Society, London School of Hygiene & Tropical Medicine, London, United Kingdom.; Department of Medicine, Georgetown University Medical Centre, Georgetown University, Washington, DC, United States.; Centre for Infectious Disease Research in Zambia, Lusaka, Zambia.; Washington University School of Medicine, St. Louis, MO, United States.; CIDRZ; Centre for Infectious Disease Research in Zambia (CIDRZ)
INTRODUCTION: Traditional patient-provider relationships privilege the providers, as they possess the formal authority and clinical knowledge applied to address illness, but providers also have discretion over how they exercise their power to influence patients' services, benefits, and sanctions. In this study, we assessed providers' exercise of discretionary power in implementing patient-centered care (PCC) practices in Lusaka, Zambia. METHODS: HIV clinical encounters between patients on antiretroviral therapy (ART) and providers across 24 public health facilities in Lusaka Province were audio recorded and transcribed verbatim. Using qualitative content analysis, we identified practices of discretionary power (DP) employed in the implementation of PCC and instances of withholding DP. A codebook of DP practices was inductively and iteratively developed. We compared outcomes across provider cadres and within sites over time. RESULTS: We captured 194 patient-provider interactions at 24 study sites involving 11 Medical Officers, 58 Clinical Officers and 10 Nurses between August 2019 to May 2021. Median interaction length was 7.5 min. In a hierarchy where providers dominate patients and interactions are rapid, some providers invited patients to ask questions and responded at length with information that could increase patient understanding and agency. Others used inclusive language, welcomed patients, conducted introductions, and apologized for delayed services, narrowing the hierarchical distance between patient and provider, and facilitating recognition of the patient as a partner in care. Although less common, providers shared their decision-making powers, allowing patients to choose appointment dates and influence regimens. They also facilitated resource access, including access to services and providers outside of scheduled appointment times. Application of DP was not universal and missed opportunities were identified. CONCLUSION: Supporting providers to recognize their power and intentionally share it is both inherent to the practice of PCC (e.g., making a patient a partner), and a way to implement improved patient support. More research is needed to understand the application of DP practices in improving the patient-centeredness of care in non-ART settings.
