'They are inconveniencing us' - exploring how gaps in patient education and patient centred approaches interfere with TB treatment adherence: perspectives from patients and clinicians in the Free State Province, South Africa

South African adolescents' lived experiences of acquired hearing loss following multidrug-resistant tuberculosis treatment

Objective

The impact of acquiring hearing loss might be exacerbated during adolescence, as this normal transition from childhood to adulthood is characterised by identity construction and social intensity. This study aimed to describe the lived experiences of South African adolescents with acquired hearing loss following aminoglycoside treatment for multidrug resistant tuberculosis.

Design

The study adopted a descriptive phenomenological design and in-depth, semi-structured interviews were conducted in English, isiZulu and Afrikaans. The data was managed and analysed according to a modified version of Hycner's framework.

Study sample

Six participants aged 16-24 years with bilateral, mild to profound hearing loss acquired from aminoglycoside treatment were recruited from two South African provinces.

Results

Three themes emerged which created a triple burden for participants. They endured socio-economic hardship encompassing limited economic and emotional support. Participants battled the consequences of life-threatening MDR-TB including illness, hospitalisation, stigma, and other challenges. Finally, participants were left with life-changing hearing loss.

Conclusion

The findings indicate the necessity of holistic management of adolescents with aminoglycoside-related acquired hearing loss and serves as motivation to improve ototoxic monitoring practices and patient uptake of monitoring services and calls for the cessation, or at least cautious use, of aminoglycosides.

Community health worker training to reduce mental health and substance use stigma towards patients who have disengaged from HIV/TB care in South Africa: protocol for a stepped wedge hybrid type II pilot implementation trial

BACKGROUND

South Africa has deployed community health workers (CHWs) to support individuals to enter and stay in HIV/TB care. Although CHWs routinely encounter patients with mental health (particularly depression) and substance use (SU) conditions that impact their engagement in HIV/TB care, CHWs are rarely trained in how to work with these patients. This contributes to mental health and SU stigma among CHWs, a known barrier to patient engagement in care. Mental health and SU training interventions could reduce CHW stigma and potentially improve patient engagement in care, but evidence of the feasibility, acceptability, and preliminary effectiveness of these interventions is scarce. Therefore, we designed a hybrid type 2 effectiveness-implementation pilot trial to evaluate the implementation and preliminary effectiveness of a CHW training intervention for reducing depression and SU stigma in the Western Cape, South Africa.

METHODS

This stepped wedge pilot trial will engage CHWs from six primary care clinics offering HIV/TB care. Clinics will be block randomized into three-step cohorts that receive the intervention at varying time points. The Siyakhana intervention involves 3 days of training in depression and SU focused on psychoeducation, evidence-based skills for working with patients, and self-care strategies for promoting CHW wellness. The implementation strategy involves social contact with people with lived experience of depression/SU during training (via patient videos and a peer trainer) and clinical supervision to support CHWs to practice new skills. Both implementation outcomes (acceptability, feasibility, fidelity) and preliminary effectiveness of the intervention on CHW stigma will be assessed using mixed methods at 3- and 6-month follow-up assessments.

DISCUSSION

This trial will advance knowledge of the feasibility, acceptability, and preliminary effectiveness of a CHW training for reducing depression and SU stigma towards patients with HIV and/or TB. Study findings will inform a larger implementation trial to evaluate the longer-term implementation and effectiveness of this intervention for reducing CHW stigma towards patients with depression and SU and improving patient engagement in HIV/TB care.

"It is not easy": Experiences of people living with HIV and tuberculosis on Tuberculosis treatment in Uganda

Background

Completion of tuberculosis (TB) treatment presents several challenges to patients, including long treatment duration, medication adverse-effects and heavy pill burden. WHO emphasize the need for patient-centered TB care, but such approaches require understanding of patient experiences and perceptions.

Methods

In 2020, we nested a qualitative study within a clinical trial that recruited 128 HIV-TB co-infected adults in Kampala receiving rifampicin-based TB treatment, alongside anti-retroviral therapy. A purposively selected sub-sample of 46 trial participants contributed to nine gender segregated focus group discussions. Of these, 12 also participated in in-depth interviews. Sessions were recorded, transcribed verbatim and translated from local languages into English. Thematic analysis focused on drug adverse-effects, use of self-prescribed medications and barriers to treatment adherence.

Results

Patients seemed more concerned about adverse effects that clinicians sometimes overlook such as change in urine color. Those who remembered pre-treatment counselling advice were disinclined to manage adverse-effects by self-prescription. Difficulty in accessing a medical practitioner was reported as a reason for self-medication. Obstacles to adherence included stigma (especially from visible adverse-effects like "red urine"), difficulties with pill size and number, discomfort with formulation and medication adverse effects.

Conclusion

Tailored pre-treatment counselling, improved access to clinical services, and simpler drug administration will deliver more patient-centered care.

Patient and provider perceptions of the relationship between alcohol use and TB and readiness for treatment: a qualitative study in South Africa

Background

Unhealthy alcohol use is widespread in South Africa and has been linked to tuberculosis (TB) disease and poor treatment outcomes. This study used qualitative methods to explore the relationship between TB and alcohol use during TB treatment.

Methods

Focus groups (FGs) were conducted with 34 participants who had previous or current drugsusceptible TB and self-reported current alcohol use. Eight interviews were conducted with healthcare workers who provide TB services in Worcester, South Africa.

Results

In this rural setting, heavy episodic drinking is normalized and perceived to be related to TB transmission and decreased adherence to TB medication. Both healthcare workers and FG participants recommended the introduction of universal screening, brief interventions, and referral to specialized care for unhealthy alcohol use. However, participants also discussed barriers to the provision of these services, such as limited awareness of the link between alcohol and TB. Healthcare workers also specified resource constraints while FG participants or patients mentioned widespread stigma towards people with alcohol concerns. Both FG participants and health providers would benefit from education on the relationship between TB and unhealthy alcohol use as well and had specific recommendations about interventions for alcohol use reduction. Healthcare workers also suggested that community health worker-delivered interventions could support access to and engagement in both TB and alcohol-related services.

Conclusion

Findings support strengthening accessible, specialized services for the identification and provision of interventions and psychosocial services for unhealthy alcohol use among those with TB.

Clinical pharmacy services for tuberculosis management: a systematic review

Objective: This study aims to systematically review the content and potential effects of clinical pharmacy services in tuberculosis (TB) care management. Methods: Searches were performed in PubMed, Embase, Cochrane, Scopus, and Web of Science databases following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Study characteristics and outcomes were extracted, and clinical pharmacy service components were characterized using the Descriptive Elements of Pharmacist Intervention Characterization Tool. Results: Twenty articles were included for full-text assessment, of which 10 fulfilled inclusion criteria, comprising 1,168 patients (N = 39 to 258 per study). These articles included five prospective cohort studies, two case-control studies, two quasi-experimental studies, and one cross-sectional study. Intervention foci within clinical pharmacy services were medication adherence (50%), medication safety (40%), education to patients/caregivers regarding needs/beliefs (30%), optimizing medication/therapy effectiveness (30%), emphasizing HRQoL (10%), and drug selections (10%). The three most frequently applied interventions were drug information/patient counseling (80%), adverse drug reaction monitoring (50%), and drug use evaluation (20%). Based on the World Health Organization (WHO) outcome classification, treatment success ranged from 72% to 93%, with higher cure outcomes (53%-86%) than treatment completion (7%-19%). Other outcomes, including isoniazid metabolites, medication counts, sputum conversion, adherence/compliance, knowledge, and quality of life, were better in the intervention group than those in comparator groups, and/or they improved over time. Risk of bias analysis indicated that the included studies were not comparable to a randomized clinical trial. Conclusion: Clinical pharmacy services as single or composite interventions potentially improve TB outcomes, but its evidence is still inconsistent and limited due to the lack of randomized controlled studies using the WHO outcome classification.

What motivated men to start PrEP? A cross-section of men starting PrEP in Buffalo city municipality, South Africa

BACKGROUND

Compared to women, South African men are less likely to know their HIV status (78% vs. 89%), have suppressed viral loads (82% vs. 90%), or access HIV prevention services. To achieve epidemic control where heterosexual sexual behavior drives transmission, interventions to improve the uptake of HIV testing services (HTS) and prevention services must also target cis-gendered, heterosexual men. There is limited understanding of these men's needs and wants with regards to accessing pre-exposure prophylaxis (PrEP).

METHODS

Adult men (≥ 18 years) from a peri-urban community in Buffalo City Municipality were offered community-based HTS. Those who received a negative HIV test result were offered community-based, same-day oral PrEP initiation. Men initiating PrEP were invited to participate in a study exploring men's HIV prevention needs and reasons for initiating PrEP. An in-depth interview guide, developed using the Network-Individual-Resources model (NIRM), explored men's perceived HIV acquisition risk, prevention needs, and preferences for PrEP initiation. Interviews were conducted by a trained interviewer in isiXhosa or English, audio-recorded and transcribed. Thematic analysis was used, guided by the NIRM to generate findings.

RESULTS

Twenty-two men (age range 18-57 years) initiated PrEP and consented to study participation. Men reported elevated HIV acquisition risk associated with alcohol use and condom-less sex with multiple partners as facilitators driving PrEP initiation. They anticipated social support from family members, their main sexual partner and close friends for their PrEP use, and discussed other men as important sources of support for PrEP initiation. Nearly all men expressed positive views of people using PrEP. Participants believed HIV testing would be a barrier for men interested in accessing PrEP. Men recommended that access to PrEP be convenient, rapid, and community-based (i.e., not clinic-based).

DISCUSSION

Self-perceived risk for HIV acquisition was a major facilitator for men's PrEP initiation. Although men expressed positive perceptions of PrEP users, they noted that HIV testing may be a barrier to PrEP initiation. Finally, men recommended convenient access points to facilitate PrEP initiation and sustained use. Gender-responsive interventions tailored to men's needs, wants, and voices will facilitate their uptake of HIV prevention services, and help to end the HIV epidemic.

Canadian tuberculosis health care workers' perspectives on education and counselling for patients and family members who are born outside of Canada

Tuberculosis health care workers (TB HCWs) in low incidence settings have important perspectives on providing TB education and counselling to patients and family members born in other countries. The purpose of this qualitative study was to explore HCWs' perspectives on barriers and facilitators for capacity-building education and counselling with patients and family members born outside of Canada experiencing advanced infectious TB in Calgary, a city in western Canada. Data were collected through semi-structured interviews and field notes and thematically analysed. Twenty-four HCWs representing clerical staff, nurses, physicians, and allied health professionals employed in TB care were interviewed. HCWs described how multi-level barriers such as patients' fear of death, complex intra-family communication, information-laden appointments, and patients' precarious employment collided resulting in overwhelmed patients and reduced connection to family. Some HCWs were unsure how to discuss TB stigma with patients and family members. HCWs perceived that increased continuity of care and providing patients and family members with digestible amounts of information earlier were important steps towards better practice. HCWs identified that patients and families could benefit from preparation for initial appointments, increased continuity, and improved patient education materials. HCWs should also receive skills-training to facilitate individual and family counselling.

Social Support, Quality of Care, and Patient Adherence to Tuberculosis Treatment in Peru: The Mediating Role of Nurse Health Education

BACKGROUND

Peru is one of the countries with the highest burden of tuberculosis (TB) and multidrug-resistant tuberculosis (MDR-TB) in the Latin American region and globally. Health education provided by nurses reinforces social support and the quality of patient care allows a greater impact on adherence to TB treatment.

PURPOSE

This study evaluated the mediating effect of treatment education between social support, quality of care, and treatment adherence in TB patients.

METHODS

A cross-sectional study was carried out considering 162 adult TB patients from four health centers of the public sector located in the center of the city of Lima, Peru. Data were collected on variables, such as social support, quality of care, health education, and adherence to TB treatment. SmartPLS was used for data analysis.

RESULTS

The results showed that social support and quality of care significantly influence health education. Likewise, health education mediates social support and quality of care for better adherence to treatment.

CONCLUSION

It is recommended that hospitals take initiatives to provide better health education on TB treatment to ensure better adherence to treatment.

Qualitative Identification of Intervention Preferences to Support Men's Engagement and Retention in TB Care in South Africa

Globally and in South African specifically, men account for 56% and 62% of all tuberculosis (TB) cases, respectively. Men are at increased risk of not accessing TB testing or treatment, and having poor treatment outcomes. Unfortunately, no interventions exist to address these issues. Toward the development of targeted, patient-centered TB care and support interventions, we used semistructured interviews to explored men's social network composition, TB testing behaviors, disclosure and treatment support, clinical experiences, and TB's influence on daily living. Data were analyzed using a thematic approach guided by the Network Individual Resource Model to identify mental and tangible resources influential and preferred during engagement in TB treatment. Men emphasized the desire for peer-to-peer support to navigate TB-related stigma and unhealthy masculinity norms. Men advocated for awareness events to educate communities about their challenges with TB. Men strongly suggested that interventions be delivered in familiar locations where men congregate. Since 2022, no TB treatment support interventions have included the preferred components or delivery modes described by men in our study. To improve men's TB-related health outcomes, the global TB community must identify and address men's unique challenges when designing interventions.

Clinical standards for the dosing and management of TB drugs

BACKGROUND: Optimal drug dosing is important to ensure adequate response to treatment, prevent development of drug resistance and reduce drug toxicity. The aim of these clinical standards is to provide guidance on 'best practice´ for dosing and management of TB drugs.METHODS: A panel of 57 global experts in the fields of microbiology, pharmacology and TB care were identified; 51 participated in a Delphi process. A 5-point Likert scale was used to score draft standards. The final document represents the broad consensus and was approved by all participants.RESULTS: Six clinical standards were defined: Standard 1, defining the most appropriate initial dose for TB treatment; Standard 2, identifying patients who may be at risk of sub-optimal drug exposure; Standard 3, identifying patients at risk of developing drug-related toxicity and how best to manage this risk; Standard 4, identifying patients who can benefit from therapeutic drug monitoring (TDM); Standard 5, highlighting education and counselling that should be provided to people initiating TB treatment; and Standard 6, providing essential education for healthcare professionals. In addition, consensus research priorities were identified.CONCLUSION: This is the first consensus-based Clinical Standards for the dosing and management of TB drugs to guide clinicians and programme managers in planning and implementation of locally appropriate measures for optimal person-centred treatment to improve patient care.

The Effectiveness of Interactive Patient Education on Adherence to Leprosy Medications in an Ambulatory Care Setting Indonesia: A Randomized Control Trial

BACKGROUND: Poor treatment adherence has been linked to recurrence and the development of antibiotic resistance in leprosy patients. Previous research has shown that structured health education programs improve treatment adherence in other patients, but similar research in leprosy patients is lacking. AIM: This study aimed to assess the effect of interactive patient education on adherence to leprosy medications in an ambulatory care setting in Indonesia. METHODS: A randomized controlled trial (RCT) was conducted between January and April 2021. The research was conducted at a public health center in West Papua, Indonesia. This RCT employed 1:1 randomization to allocate participants to one of two groups. Eligibility criteria included those aged over 18 years old and diagnosed with leprosy at least 6 months. An interactive patient education program included four intervention steps that lasted 1 month, with four sessions lasting 60–90 min each week. The Morisky Medication Adherence Scale was used to assess medication adherence. The difference-in-differences technique was used to evaluate the variances between T0 and T1 and T0 for the intervention versus control groups (DID). RESULTS: Approximately, 200 participants agreed to join in this study (response rate = 72.5%). An interactive patient education program improved outcomes relative to the control at T1; medication adherence increased 0.11 (95% CI 0.01–0.25). At T2, improved outcomes relative to the control were observed in medication adherence (DID coefficient 0.31 (95% CI 0.10–0.59). CONCLUSIONS: This study demonstrates that an interactive patient education program could effectively enhance medication adherence. Therefore, it is advised that health care professionals working with leprosy patients participate in the development of patient education programs and establish therapeutic partnerships with their patients.

Linkage to TB care: A qualitative study to understand linkage from the patients' perspective in the Western Cape Province, South Africa

BACKGROUND

Delayed linkage to tuberculosis (TB) treatment leads to poor patient outcomes and increased onward transmission. Between 12% and 25% of people diagnosed with TB are never linked to a primary health care facility for continued care. The TB health program is for creating processes that promote and facilitates easy access to care. We explored how TB patients experience TB services and how this influenced their choices around linkage to TB care and treatment.

METHODS

We enrolled 20 participants routinely diagnosed with TB in hospital or at primary health care facilities (PHC) in a high TB/HIV burdened peri-urban community in South Africa. Using the Western Cape Provincial Health Data centre (PHDC) which consolidates person-level clinical data, we used dates of diagnosis and treatment initiation to select participants who had been linked (immediately, after a delay, or never). Between June 2019 and January 2020, we facilitated in-depth discussions to explore both the participants' experience of their TB diagnosis and their journey around linking to TB care at a primary health care facility. We analysed the data using case descriptions.

RESULTS

Twelve of twenty (12/20) participants interviewed who experienced a delay linking were diagnosed at the hospital. Participants who experienced delays in linking or never linked explained this as a result of lack of information and support from health care providers. Unpleasant previous TB treatment episodes made it difficult to 'face' TB again and being uncertain of their TB diagnosis. In contrast, participants said the main motivator for linking was a personal will to get better.

CONCLUSION

The health care system, especially in hospitals, should focus on strengthening patient-centred care. Communication and clear messaging on TB processes is key, to prepare patients in transitioning from a hospital setting to PHC facilities for continuation of care. This should not just include a thorough explanation of their TB diagnosis but ensure that patients understand treatment processes. Former TB patients may require additional counselling and support to re-engage in care.
