Abstract BackgroundA 12-dose, once-weekly regimen of isoniazid and rifapentine (3HP) is effective in preventing tuberculosis (TB) among people living with HIV (PLHIV). We sought to identify potential barriers to and facilitators of 3HP implementation from the perspective of PLHIV and health workers in a routine HIV care setting in Kampala, Uganda.MethodsWe conducted semi-structured interviews with 25 PLHIV and 10 health workers at an HIV/AIDS clinic in Kampala, Uganda. For both groups, we explored their understanding and interpretations of TB and TB preventive therapy (TPT), and perceptions about social and contextual factors that might influence willingness of PLHIV to initiate and complete 3HP. We analyzed the data using an inductive thematic approach and aligned the emergent themes to the Behavior Change Wheel framework to identify sources of behavior and targeted behavior change interventions.ResultsFacilitators for uptake and completion of 3HP among PLHIV were fear of contracting TB, awareness of being potentially at risk of getting TB, willingness to take TPT, trust in health workers, and the perceived benefits of DOT and SAT. Barriers included inadequate understanding of TPT, fear of potential side effects, concerns about effectiveness of 3HP as well as the perceived challenges of DOT or SAT. Among health workers, perceived facilitators included knowledge that TB is a common cause of mortality, fear of getting TB, patient trust in their health workers, potential for once-weekly dosing and the benefits of TPT delivery. Health workers perceived potential barriers for PLHIV as being: inadequate understanding of TB and TPT, TB associated stigma, potential side effects, pill burden and challenges of taking TPT. Additional barriers included a lack of experience among health workers with the use of digital technology to monitor patient care.Conclusions Using a formative qualitative and comprehensive theoretical approach, we identified key sources of behavior that could be used to guide selection of appropriate intervention to optimize 3HP scale up among PLHIV in high burden settings.

Abstract Background A 12-dose, once-weekly regimen of isoniazid and rifapentine (3HP) is effective in preventing tuberculosis (TB) among people living with HIV (PLHIV). We sought to identify potential barriers to and facilitators of acceptance and completion of 3HP treatment from the perspective of people living with HIV (PLHIV) and health workers in a routine HIV care setting in Kampala, Uganda. Methods We conducted semi-structured interviews with 25 PLHIV and 10 health workers at an HIV/AIDS clinic in Kampala, Uganda. For both groups, we explored their understanding and interpretations of TB and TB preventive therapy (TPT), and perceptions about social and contextual factors that might influence the willingness of PLHIV to initiate and complete 3HP. We analyzed the data using an inductive thematic approach and aligned the emergent themes to the Behavior Change Wheel framework to identify sources of behavior and targeted behavior change interventions. Results Facilitators of acceptance and completion of 3HP treatment among PLHIV were fear of contracting TB, awareness of being at risk of getting TB, willingness to take TPT, trust in health workers, and the perceived benefits of directly observed therapy (DOT) and self-administered therapy (SAT) 3HP delivery strategies. Barriers included inadequate understanding of TPT, fear of potential side effects, concerns about the effectiveness of 3HP, and the perceived challenges of DOT or SAT. Among health workers, perceived facilitators included knowledge that TB is a common cause of mortality for PLHIV, fear of getting TB, and trust in the health workers by PLHIV, the advantages of once-weekly 3HP dosing, and the benefits of DOT and SAT 3HP delivery strategies. Health worker-reported barriers for PLHIV included inadequate understanding of TB and benefits of TPT, TB-associated stigma, potential side effects pill burden, and challenges of DOT and SAT 3HP delivery strategies. Lack of experience in the use of digital technology to monitor patient care was identified as a health worker-specific barrier. Identified intervention functions to address the facilitators or barriers included education, persuasion, environmental restructuring, enablement, and training. Conclusions Using a formative qualitative and comprehensive theoretical approach, we identified key barriers, facilitators, and appropriate interventions, including patient education, enhancing trust, and patient-centered treatment support that could be used to optimize the delivery of 3HP to PLHIV in our setting. These interventions are likely generalizable to other clinical interventions in similar populations in sub-Saharan Africa and other TB high-burden settings.

Abstract Background: Isoniazid Preventive Therapy (IPT) reduced Tuberculosis (TB) among People Living with HIV (PLHIV). Despite this, uptake has been reported to be sub-optimal . We describe characteristics of visits in which PLHIV were screened TB negative (as the main source for IPT initiation), determine characteristics of visits in which PLHIV were initiated on IPT as well as determined factors associated with IPT initiation to inform program scale up and improve quality of service.Methods : Retrospective cohort study design which involved PLHIV enrolled into care and treatment clinics in Dar es Salaam, Iringa and Njombe regions from January 2012 to December 2016. The study aimed at evaluating implementation of IPT among PLHIV. Data analysis was conducted using STATA.Results: A total 173,746 were enrolled in CTC in the 3 regions during the period of follow up and made a total of 2,638,876 visits. Of the eligible visits, only 24,429 (1.26%) were initiated on IPT. In multivariate analysis, 50 years and more (aOR=3.42, 95% CI: 3.07-3.82, P<0.01), bedridden functional status individuals with bedridden functional status (aOR=4.56, 95% CI:2.45-8.49, P<0.01) and WHO clinical stage II had higher odds of IPT initiation (aOR=1.18, 95% CI:1.13-1.23, P<0.01). Furthermore, enrolment in 2016 (aOR=2.92, 95% CI:2.79-3.06, P<0.01), enrolment in hospitals (aOR=1.84, 95% CI:1.77-1.90, P<0.01), enrolment in public health facilities (aOR=1.82, 95% CI: 1.75-1.90, P<0.01) and been on care for more than one year (aOR=6.77, 95% CI: 5.25-8.73, P<0.000) were also more likely to be initiated on IPT. Enrollment in Iringa (aOR=0.44, 95% CI: 0.41-0.47, P<0.01) and good adherence (aOR=0.56, 95% CI 0.47-0.67, P<0.01) was less likely to be initiated on IPT.Conclusions: Our study documented low IPT initiation proportion among those who were enrolled in HIV care and eligible in the 3 regions during the study period. Variations in IPT initiation among regions signals different dynamics affecting IPT uptake in different regions and hence customized approaches in quality improvement. Implementation research is needed to understand health system as well as cultural barriers in the uptake of IPT intervention.

We assessed the prevalence of isoniazid preventive therapy (IPT) uptake and explored factors associated with IPT non-uptake among people living with HIV (PLHIV) using nationally representative data from the Zimbabwe Population-based HIV Impact Assessment (ZIMPHIA) 2015–2016. This was a cross-sectional study of 3418 PLHIV ZIMPHIA participants eligible for IPT, aged ≥15 years and in HIV care. Logistic regression modeling was performed to assess factors associated with self-reported IPT uptake. All analyses accounted for multistage survey design. IPT uptake among PLHIV was 12.7% (95% confidence interval (CI): 11.4–14.1). After adjusting for sex, age, rural/urban residence, TB screening at the last clinic visit, and hazardous alcohol use, rural residence was the strongest factor associated with IPT non-uptake (adjusted OR (aOR): 2.39, 95% CI: 1.82–3.12). Isoniazid preventive therapy non-uptake having significant associations with no TB screening at the last HIV care (aOR: 2.07, 95% CI: 1.54–2.78) and with hazardous alcohol use only in urban areas (aOR: 10.74, 95% CI: 3.60–32.0) might suggest suboptimal IPT eligibility screening regardless of residence, but more so in rural areas. Self-reported IPT use among PLHIV in Zimbabwe was low, 2 years after beginning national scale-up. This shows the importance of good TB screening procedures for successful IPT implementation.

Global HIV program stakeholders, including the US President’s Emergency Plan for AIDS Relief (PEPFAR), are undertaking efforts to ensure that eligible people living with HIV (PLHIV) receiving antiretroviral treatment (ART) receive a course of TB preventive treatment (TPT). In PEPFAR programming, this effort may require providing TPT not only to newly diagnosed PLHIV as part of HIV care initiation, but also to treatment-experienced PLHIV stable on ART who may not have been previously offered TPT. TPT scale-up is occurring at the same time as a trend to provide more person-centered HIV care through differentiated service delivery (DSD). In DSD, PLHIV stable on ART may receive less frequent clinical follow-up or receive care outside the traditional clinic-based model. The misalignment between traditional delivery of TPT and care delivery in innovative DSD may require adaptations to TPT delivery practices for PLHIV. Adaptations include components of planning and operationalization of TPT in DSD, such as determination of TPT eligibility and TPT initiation, and clinical management of PLHIV while on TPT. A key adaptation is alignment of timing and location for TPT and ART prescribing, monitoring, and dispensing. Conceptual examples of TPT delivery in DSD may help program managers operationalize TPT in HIV care.

Background Information on how well Isoniazid Preventive Therapy (IPT) works on reducing TB incidence among people living with HIV (PLHIV) in routine settings using robust statistical methods to establish causality in observational studies is scarce. Objectives To evaluate the effectiveness of IPT in routine clinical settings by comparing TB incidence between IPT and non-IPT groups. Methods We used data from PLHIV enrolled in 315 HIV care and treatment clinic from January 2012 to December 2016. We used Inverse Probability of Treatment Weighting to adjust for the probability of receiving IPT; balancing the baseline covariates between IPT and non-IPT groups. The effectiveness of IPT on TB incidence was estimated using Cox regression using the weighted sample. Results Of 171,743 PLHIV enrolled in the clinics over the five years, 10,326 (6.01%) were excluded leaving 161,417 available for the analysis. Of the 24,800 who received IPT, 1.00% developed TB disease whereas of the 136,617 who never received IPT 6,085 (4.98%) developed TB disease. In 278,545.90 person-years of follow up, a total 7,052 new TB cases were diagnosed. Using the weighted sample, the overall TB incidence was 11.57 (95% CI: 11.09–12.07) per 1,000 person-years. The TB incidence among PLHIV who received IPT was 10.49 (95% CI: 9.11–12.15) per 1,000 person-years and 12.00 (95% CI: 11.69–12.33) per 1,000 person-years in those who never received IPT. After adjusting for other covariates there was 52% lower risk of developing TB disease among those who received IPT compared to those who never received IPT: aHR = 0.48 (95% CI: 0.40–0.58, P<0.001). Conclusion IPT reduced TB incidence by 52% in PLHIV attending routine CTC in Tanzania. IPTW adjusted the groups for imbalances in the covariates associated with receiving IPT to achieve comparable groups of IPT and non-IPT. This study has added evidence on the effectiveness of IPT in routine clinical settings and on the use of IPTW to determine impact of interventions in observational studies.

Abstract BackgroundTuberculosis (TB) remains a significant public health concern, and a leading cause of ill-health and death globally. More so, People living with HIV have been shown to carry an increased risk of developing TB with an estimated one-third of deaths in this population. The World Health Organization recommends systematic and routine screening of PLHIV for TB on every clinic visit and further testing using sputum for those with a positive TB screen test. Not all PLHIV with a positive TB screen test in Ghana are further tested for TB using sputum and the factors for this are not well understood. This study assessed factors associated with sputum ordering for TB diagnosis in PLHIV who were screened positive for TB in three hospitals providing HIV care and treatment services in the Greater Accra region of Ghana.MethodsMixed method study performed at three purposively selected hospitals providing HIV care and treatment services in the Greater Accra region. The study involved a cross sectional review of patients’ charts and in-depth interviews with health workers involved in the care and treatment of PLHIV. Quantitative data was analyzed using STATA version 15. Chi square test was used for bivariate analysis. Logistic regression was used for multivariate analysis. P≤ 0.05 was considered statistically significant. Inductive thematic analysis was used to determine emerging themes from the interviews. The major themes were represented with representative quotations.ResultsFour hundred (400) patient charts were reviewed of which 67.7% were female with median age of 39 (IQR 31-49). TB screening was recorded in 78% (95% CI 73.6, 82.0) of the patients of whom ninety-two (92) patients had a positive TB screen test. Only 53 (57.6%) who had a positive screen test had sputum ordered for further TB testing. In the multivariate analysis, patient general appearance described as abnormal (OR=3.05, p=0.036), having more than one TB symptom (OR=3.42, p=0.028) and presence of an alternative presumptive diagnosis (OR=0.34, p=0.023) were associated with having a sputum test ordered. High patient numbers, inability to produce sputum, unwillingness of the not so sick patients to provide sputum and the costs associated with chest X-ray were perceived as the challenges to further testing for TB.ConclusionTB screening in PLHIV is still lower than recommended and almost half of PLHIV with a positive TB screen test did not have a sputum test documented. Sputum testing was likely to be done in patients with an abnormal general appearance and more than one TB symptom and unlikely in those with an alternative presumptive diagnosis. High workload, costs of TB tests, lack of training for health workers and inability to produce sputum by patients were the barriers to sputum testing highlighted by the health workers.

ObjectivesTo identify factors to consider when integrating physiotherapy (PT) into an interprofessional outpatient HIV care setting from the perspective of healthcare professionals and adults living with HIV.DesignWe conducted a qualitative descriptive study using semi-structured interviews (healthcare professionals) and focus groups (adults living with HIV). We asked participants their perspectives on barriers, facilitators and strategies to accessing and participating in outpatient PT, important characteristics physiotherapists should possess working in outpatient HIV care, content and structure of PT delivery, and programme evaluation.Recruitment and settingWe purposively sampled healthcare professionals based on their experiences working in interprofessional HIV care and recruited adults with HIV via word of mouth and in collaboration with an HIV-specialty hospital in Toronto, Canada. Interviews were conducted via Skype or in-person and focus groups were conducted in-person at the HIV-specialty hospital.Participants12 healthcare professionals with a median of 12 years experience in HIV care, and 13 adults living with HIV (11 men and 2 women) with a median age of 50 years and living with a median of 6 concurrent health conditions in addition to HIV.ResultsOverall impressions of PT in outpatient HIV care and factors to consider when implementing PT into an interprofessional care setting include: promoting the role of, and evidence for, PT in outpatient HIV care, structuring PT delivery to accommodate the unique needs and priorities of adults living with HIV, working collaboratively with a physiotherapist on the healthcare team and evaluating rehabilitation as a component of interprofessional care.ConclusionsMultiple factors exist for consideration when implementing PT into an interprofessional outpatient HIV care setting. Results provide insight for integrating timely and appropriate access to evidence-informed rehabilitation for people living with chronic and episodic illness, such as HIV.

Abstract Background Uptake of Isoniazid Preventive Therapy (IPT) among People Living with HIV in Zambia has continued to be low despite various evidence for its added benefit in reducing TB incidence and mortality when taken with antiretroviral therapy. In 2017, only 18% of People Living with HIV newly enrolled in care were initiated on IPT in Zambia. Main text Various challenges including policy and management level factors, supply chain factors, health worker perceptions about IPT, monitoring and evaluation factors and limited demand creation activities have constrained the scale up of IPT in Zambia. Lessons that have been learnt while addressing the above challenges are shared and they can be applied by government ministries, project managers, public health specialists to strengthen IPT activities in their settings. Conclusion Zambia has both a high burden of TB and HIV and without preventing new cases of TB from reactivation of latent TB infection, it will be difficult to control TB. All stakeholders involved in prevention of TB among PLHIV need to commit to addressing the challenges limiting scale up of IPT.

Tuberculosis (TB) remains a leading cause of morbidity and mortality among people living with HIV. HIV-associated TB disproportionally affects African countries, particularly vulnerable groups at risk for both TB and HIV. Currently available TB diagnostics perform poorly in people living with HIV; however, new diagnostics such as Xpert Ultra and lateral flow urine lipoarabinomannan assays can greatly facilitate diagnosis of TB in people living with HIV. TB preventive treatment has been underutilized despite its proven benefits independent of antiretroviral therapy (ART). Shorter regimens using rifapentine can support increased availability and scale-up. Mortality is high in people with HIV-associated TB, and timely initiation of ART is critical. Programs should provide decentralized and integrated TB and HIV care in settings with high burden of both diseases to improve access to services that diagnose TB and HIV as early as possible. The new prevention and diagnosis tools recently recommended by WHO offer an immense opportunity to advance our fight against HIV-associated TB. They should be made widely available and scaled up rapidly supported by adequate funding with robust monitoring of the uptake to advance global TB elimination.
