Impact of peer-trainer leadership style on uptake of a peer led educational outreach intervention to improve tuberculosis care and outcomes in Malawi: a qualitative study

Barriers to tuberculosis treatment adherence in high-burden tuberculosis settings in Ashanti region, Ghana: a qualitative study from patient's perspective

BACKGROUND

Despite having an effective community-based Directly Observed Therapy Short-course (DOTS) strategy for tuberculosis (TB) care, treatment adherence has been a major challenge in many developing countries including Ghana. Poor adherence results in discontinuity of treatment and leads to adverse treatment outcomes which pose an increased risk of drug resistance. This study explored barriers to TB treatment adherence and recommended potential patient-centered strategies to improve treatment adherence in two high-burden TB settings in the Ashanti region of Ghana.

METHODS

The study was conducted among TB patients who defaulted on treatment in the Obuasi Municipal and Obuasi East districts in the Ashanti region. A qualitative phenomenology approach was used to explore the barriers to TB treatment adherence. Purposive sampling was adopted to select study participants with different sociodemographic backgrounds and experiences with TB care. Eligible participants were selected by reviewing the medical records of patients from health facility TB registers (2019-2021). Sixty-one (61) TB patients met the eligibility criteria and were contacted via phone call. Out of the 61 patients, 20 were successfully reached and consented to participate. In-depth interviews were conducted with participants using a semi-structured interview guide. All interviews were audio recorded and transcribed verbatim. The transcripts were imported into Atlas.ti version 8.4 software and analyzed using thematic content analysis.

RESULTS

Food insecurity, cost of transportation to the treatment center, lack of family support, income insecurity, long distance to the treatment center, insufficient knowledge about TB, side effect of drugs, improvement in health after the intensive phase of the treatment regimen, and difficulty in accessing public transportation were the main co-occurring barriers to treatment adherence among the TB patients.

CONCLUSION

The main barriers to TB treatment adherence identified in this study reveal major implementation gaps in the TB programme including gaps related to social support, food security, income security, knowledge, and proximity to treatment centers. Hence, to improve treatment adherence there is a need for the government and the National Tuberculosis Programme (NTP) to collaborate with different sectors to provide comprehensive health education, social and financial support as well as food aid to TB patients.

Barriers and facilitators to implementing the HEADSS psychosocial screening tool for adolescents living with HIV/AIDS in teen club program in Malawi: health care providers perspectives

BACKGROUND

Adolescents living with HIV (ALHIV) are at high risk of experiencing mental health problems. Depression is a major contributor to the burden of HIV-related disease amongst ALHIV and is significantly linked to non-adherence to anti-retroviral therapy (ART), yet it is under-recognized. In 2015, the Baylor College of Medicine International Pediatric AIDS Initiative (BIPAI) recommended that the psychosocial screening tool Home, Education, Activities, Drugs, Sexuality, Suicide/Depression (HEADSS) be used to screen ALHIV in Malawi who were part of an adolescent antiretroviral therapy program termed "Teen Club". However, the HEADSS tool has been substantially under-utilized. This study assessed barriers and facilitators to implementing HEADSS for ALHIV attending Teen Club Program in four selected health facilities in Malawi.

METHODS

We conducted a qualitative study using semi-structured interviews at four program sites (one district hospital and one health center each in two districts) between April and May 2019. Twenty key informants were purposively selected to join this study based on their role and experiences. We used the five domains of the Consolidated Framework for Implementation Research (CFIR) to guide the development of the interview guides, analysis and interpretation of results.

RESULTS

Barriers included inadequate planning for integration of the HEADSS approach; concerns that the HEADSS tool was too long, time consuming, lacked appropriate cultural context, and increased workload; and reports by participants that they did not have knowledge and skills to screen ALHIV using this tool. Facilitators to implementing the screening were that health care providers viewed screening as a guide to better systematic counselling, believed that screening could build better client provider relationship, and thought that it could fit into the existing work practice since it is not complex.

CONCLUSIONS

A culturally adapted screening tool, especially one that can be used by non-clinicians such as lay health workers, would improve the ability to address mental health needs of ALHIV in many primary care and social service settings where resources for professional mental health staff are limited. These findings are a springboard for efforts to culturally adapt the HEADSS screening tool for detection of mental and risky behaviors among ALHIV attending ART program in Malawi.

Process evaluation of an implementation strategy to support uptake of a tuberculosis treatment adherence intervention to improve TB care and outcomes in Malawi

OBJECTIVE

To assess implementation and to identify barriers and facilitators to implementation, sustainability and scalability of an implementation strategy to provide lay health workers (LHWs) with the knowledge, skills and tools needed to implement an intervention to support patient tuberculosis (TB) treatment adherence.

DESIGN

Mixed-methods design including a cluster randomised controlled trial and process evaluation informed by the RE-AIM framework.

SETTING

Forty-five health centres (HCs) in four districts in the south east zone of Malawi, who had an opportunity to receive cascade training.

PARTICIPANTS

Forty-five peer-trainers (PTs), 23 patients and 20 LHWs.

INTERVENTION

Implementation strategy employing peer-led educational outreach, a clinical support tool and peer support network to implement a TB treatment adherence intervention.

OUTCOME MEASURES

Process data were collected from study initiation to the end-of-study PT meeting, and included: LHW and patient interviews, quarterly PT meeting notes, training logs and study team observations and meeting notes. Data sources were first analysed in isolation, followed by method, data source and analyst triangulation. Analyses were conducted independently by two study team members, and themes revised through discussion and involvement of additional study team members as needed.

RESULTS

Forty-one HCs (91%) trained at least one LHW. Of 256 LHWs eligible to participate at study start 152 (59%) completed training, with the proportion trained per HC ranging from 0% to 100% at the end of initial cascade training. Lack of training incentives was the primary barrier to implementation, with intrinsic motivation to improve knowledge and skills, and to improve patient care and outcomes the primary facilitators of participation.

CONCLUSION

We identified important challenges to and potential facilitators of implementation, scalability and sustainability, of the TB treatment adherence intervention. Findings provide guidance to scale-up, and use of the implementation strategies employed, to address LHW training and supervision in other areas.

Impact of a tuberculosis treatment adherence intervention versus usual care on treatment completion rates: results of a pragmatic cluster randomized controlled trial

BACKGROUND

With the global shortage of skilled health workers estimated at 7.2 million, outpatient tuberculosis (TB) care is commonly task-shifted to lay health workers (LHWs) in many low- and middle-income countries where the shortages are greatest. While shown to improve access to care and some health outcomes including TB treatment outcomes, lack of training and supervision limit the effectiveness of LHW programs. Our objective was to refine and evaluate an intervention designed to address common causes of non-adherence to TB treatment and LHW knowledge and skills training needs.

METHODS

We employed a pragmatic cluster randomized controlled trial. Participants included 103 health centres (HCs) providing TB care in four districts in Malawi, randomized 1:1 stratified by district and HC funding (Ministry of Health, non-Ministry funded). At intervention HCs, a TB treatment adherence intervention was implemented using educational outreach, a point-of-care reminder tool, and a peer support network. Clusters in the control arm provided usual care. The primary outcome was the proportion of patients with successful TB treatment (i.e., cure or treatment completion). We used a generalized linear mixed model, with district as a fixed effect and HC as a random effect, to compare proportions of patients with treatment success, among the trial arms, with adjustment for baseline differences.

RESULTS

We randomized 51 HCs to the intervention group and 52 HCs to the control group. Four intervention and six control HCs accrued no eligible patients, and 371 of 1169 patients had missing outcome, HC, or demographic data, which left 74 HCs and 798 patients for analysis. Randomization group was not related to missing outcome, however, district, age, and TB type were significantly related and included in the primary analysis model. Among the 1153 patients with HC and demographic data, 297/605 (49%) and 348/548 (64%) in the intervention and control arms, respectively, had treatment success. The intervention had no significant effect on treatment success (adjusted odds ratio 1.35 [95% confidence interval 0.93-1.98]).

CONCLUSION

We found no significant effect of the intervention on TB treatment outcomes with high variability in implementation quality, highlighting important challenges to both scale-up and sustainability.
