"Treatment is of primary importance, and social assistance is secondary": A qualitative study on the organisation of tuberculosis (TB) care and patients' experience of starting and staying on TB treatment in Riga, Latvia

Validation of the Working Alliance Inventory- Short Form for Patient (WAI-S-P) in Peruvian Adults

Background

Although the importance of the therapeutic alliance in the treatment process and health outcomes is recognized, so far, there has been no evaluation in the Peruvian context that considers possible individual differences that could influence this assessment.

Purpose

This study assessed the psychometric properties of the WAI-S-P in a sample of individuals from Peru who are receiving psychological therapy. Furthermore, a network analysis was conducted to investigate the direct relationships between the therapeutic alliance and several relevant sociodemographic variables.

Methods

The short version of the Working Alliance Inventory was used in a sample of 241 participants (Mage=32.58, SD=12.67) that had attended less than 6 sessions. Three models were considered, including a three-factor and a two-factor correlated model, as well as a bifactor model. In addition, a network of partial associations was created including the overall therapeutic alliance, sex, age, and number of psychotherapeutic sessions.

Results

The bifactor model, with an overall therapeutic alliance factor and two specific factors ("contact" and "contract"), better fit the data. Invariance of the structure by sex and age showed equitable measurement. On the other hand, network analysis revealed a positive correlation between total session attendance and therapeutic alliance. Men reported higher therapeutic alliance, while women had higher total session attendance.

Conclusion

The results of this study suggest that the therapeutic alliance is better represented by a bifactor model and demonstrates invariance across sex and age in Peruvian adults. Additionally, findings indicate that differences in life experiences and the sex of patients may need to be verified in future studies to better understand nuanced needs in forming therapeutic alliances at least in the early stages of session attendance.

Forgiveness Is the Attribute of the Strong: Nonadherence and Regimen Shortening in Drug-sensitive Tuberculosis

Rationale: "Forgiveness" charts the ability of a drug or regimen to withstand nonadherence without negative clinical consequences. Objectives: We aimed to determine the influence of regimen length, regimen drugs, and dosing, and when during treatment nonadherence occurs on the forgiveness of antituberculosis regimens. Methods: Using data from three randomized controlled trials comparing experimental 4-month regimens for drug-sensitive tuberculosis with the standard 6-month regimen, we used generalized linear models to examine how the risk of a negative composite outcome changed as dose-taking decreased. The percentage of doses taken and the absolute number of doses missed were calculated during the intensive and continuation phases of treatment, and overall. A mediation analysis was undertaken to determine how much the association between intensive phase dose-taking and the negative composite outcome was mediated through continuation phase dose-taking. Measurements and Main Results: Forgiveness of the 4- and 6-month regimens did not differ for any treatment period. Importantly, 4-month regimens were no less forgiving of small numbers of absolute missed doses than the 6-month regimen (e.g., for 3-7 missed doses vs. no missed doses [baseline], 6-month regimen adjusted risk ratio 1.65 [95% confidence interval, 0.80-3.41] and 4-month regimens 1.80 [1.33-2.45]). No 4-month regimen was conclusively more forgiving than another. We found evidence of mediation by continuation phase dose-taking on the intensive phase dose-taking and negative composite outcome relationship. Conclusions: With the current appetite for, and progress toward, shorter drug-sensitive tuberculosis regimens worldwide, we offer reassurance that shorter regimens are not necessarily less forgiving of nonadherence. Given the importance of continuation phase adherence, patient support during this period should not be neglected.

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.

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.

Barriers and enablers to implementing tuberculosis control strategies in EU and European Economic Area countries: a systematic review

Meeting the 2035 WHO targets of reducing tuberculosis incidence by 90% from 2015 levels requires the implementation of country-specific tuberculosis control strategies. This systematic review aims to identify factors that facilitate or impede the implementation of such strategies in EU and European Economic Area (EEA) settings. Focusing on providers of care, health system constraints, and social and political factors, this Review complements available evidence on the accessibility of tuberculosis services to recipients of care. Databases were searched for EU and EEA articles published between Jan 1, 1997, and Nov 6, 2020, that presented empirical data on tuberculosis policies, strategies, guidelines, or interventions. 2061 articles were screened and 65 were included. The most common barrier to tuberculosis control strategies described the divergence of health-care practices from guidelines, often related to inadequate knowledge or perceived usefulness of the guidelines by clinicians. The most commonly identified enabler to tuberculosis control strategies was the documented positive attitudes of health-care workers towards tuberculosis programmes. Divergence between clinical practice and guidelines was described in most EU and EEA settings, indicating the need for a focused review of guideline adherence. Strengths of this study involve its broad inclusion criteria and wide range of tuberculosis control strategies analysed.

TB management in the European Union/European Economic Area: a multi-centre survey

BACKGROUND:

Essential TB care in the European Union/European Economic Area (EU/EEA) comprises 21 standards for the diagnosis, treatment and prevention of TB that constitute the European Union Standards for Tuberculosis Care (ESTC).

METHODS:

In 2017, we conducted an audit on TB management and infection control measures against the ESTC standards. TB reference centres in five EU/EEA countries were purposely selected to represent the heterogeneous European TB burden and examine geographic variability.

RESULTS:

Data from 122 patients, diagnosed between 2012 and 2015 with multidrug-resistant TB (n = 49), extensively drug-resistant TB (XDR-TB) (n = 11), pre-XDR-TB (n = 29) and drug-susceptible TB (n = 33), showed that TB diagnosis and treatment practices were in general in agreement with the ESTC.

CONCLUSION:

Overall, TB management and infection control practices were in agreement with the ESTC in the selected EU/EEA reference centres. Areas for improvement include strengthening of integrated care services and further implementation of patient-centred approaches.

Relational Dynamics of Treatment Behavior Among Individuals with Tuberculosis in High-Income Countries: A Scoping Review

Although tuberculosis (TB) incidence has significantly declined in high-income, low-incidence (HILI) countries, challenges remain in managing TB in vulnerable populations who may struggle to stay on anti-TB treatment (ATT). Factors associated with non-adherence to ATT are well documented; however, adherence is often narrowly conceived as a fixed binary variable that places emphasis on individual agency and the act of taking medicines, rather than on the demands of being on treatment more broadly. Further, the mechanisms through which documented factors act upon the experience of being on treatment are poorly understood. Adopting a relational approach that emphasizes the embeddedness of individuals within dynamic social, structural, and health systems contexts, this scoping review aims to synthesize qualitative evidence on experiences of being on ATT and mechanisms through which socio-ecological factors influence adherence in HILI countries. Six electronic databases were searched for peer-reviewed literature published in English between January 1990 and May 2020. Additional studies were obtained by searching references of included studies. Narrative synthesis was used to analyze qualitative data extracted from included studies. Of 28 included studies, the majority (86%) reported on health systems factors, followed by personal characteristics (82%), structural influences (61%), social factors (57%), and treatment-related factors (50%). Included studies highlighted three points that underpin a relational approach to ATT behavior: 1) individual motivation and capacity to take ATT is dynamic and intertwined with, rather than separate from, social, health systems, and structural factors; 2) individuals' pre-existing experiences of health-seeking influence their views on treatment and their ability to commit to long-term regular medicine-taking; and 3) social, cultural, and political contexts play an important role in mediating how specific factors work to support or hinder ATT adherence behavior in different settings. Based on our analysis, we suggest that person-centered clinical management of tuberculosis should 1) acknowledge the ways in which ATT both disrupts and is managed within the everyday lives of individuals with TB; 2) appreciate that individuals' circumstances and the support and resources they can access may change over the course of treatment; and 3) display sensitivity towards context-specific social and cultural norms affecting individual and collective experiences of being on ATT.

All nonadherence is equal but is some more equal than others? Tuberculosis in the digital era

Adherence to treatment for tuberculosis (TB) has been a concern for many decades, resulting in the World Health Organization's recommendation of the direct observation of treatment in the 1990s. Recent advances in digital adherence technologies (DATs) have renewed discussion on how to best address nonadherence, as well as offering important information on dose-by-dose adherence patterns and their variability between countries and settings. Previous studies have largely focussed on percentage thresholds to delineate sufficient adherence, but this is misleading and limited, given the complex and dynamic nature of adherence over the treatment course. Instead, we apply a standardised taxonomy - as adopted by the international adherence community - to dose-by-dose medication-taking data, which divides missed doses into 1) late/noninitiation (starting treatment later than expected/not starting), 2) discontinuation (ending treatment early), and 3) suboptimal implementation (intermittent missed doses). Using this taxonomy, we can consider the implications of different forms of nonadherence for intervention and regimen design. For example, can treatment regimens be adapted to increase the "forgiveness" of common patterns of suboptimal implementation to protect against treatment failure and the development of drug resistance? Is it reasonable to treat all missed doses of treatment as equally problematic and equally common when deploying DATs? Can DAT data be used to indicate the patients that need enhanced levels of support during their treatment course? Critically, we pinpoint key areas where knowledge regarding treatment adherence is sparse and impeding scientific progress.

Are people-centred mental health services acceptable and feasible in Timor-Leste? A qualitative study

People-centred mental healthcare is an influential concept for health system strengthening and sustainable development that has been developed and promoted primarily in Western contexts. It characterizes service users, families and communities as active participants in health system development. However, we have limited understanding of how well people-centred mental healthcare aligns with the multiplicity of peoples, cultures, languages and contexts in low- and middle-income countries (LMICs). Timor-Leste, a lower-middle income country in South-East Asia, is in the process of strengthening its National Mental Health Strategy 2018-22 to align with people-centred mental healthcare. To support the implementation of this Strategy, this study investigated the acceptability and feasibility of people-centred mental health services in Timor-Leste. In-depth semi-structured individual (n = 57) and group interviews (n = 15 groups) were conducted with 85 adults (≥18 years). Participants were service users, families, decision-makers, service providers and members of civil society and multilateral organizations across national and sub-national sites. Government and non-government mental health and social care was also observed. Framework analysis was used to analyse interview transcripts and observation notes. The study found that the ecology of mental healthcare in Timor-Leste is family-centred and that government mental health services are largely biomedically oriented. It identified the following major challenges for people-centred mental health services in Timor-Leste: different sociocultural perceptions of (in)dividual personhood, including a diminished status of people with mental illness; challenges in negotiating individual and family needs; a reliance on and demand for biomedical interventions; and barriers to health service access and availability. Opportunities for people-centred mental healthcare are better available within the social and disability sectors, which focus on social inclusion, human rights and peer support. Accounting for local cultural knowledge and understandings will strengthen design and implementation of people-centred mental healthcare in LMIC settings.

Patients' perspectives of tuberculosis treatment challenges and barriers to treatment adherence in Ukraine: a qualitative study

OBJECTIVES

To understand the challenges faced by patients with tuberculosis (TB) and factors that influence TB treatment adherence in Ukraine.

DESIGN

Qualitative study.

SETTING

TB treatment facilities in Kyiv Oblast, Ukraine.

PARTICIPANTS

Sixty adults who had undergone treatment for drug-sensitive TB between June 2012 and August 2015.

METHODS

We conducted semistructured, in-depth, individual interviews among a purposively selected clinical sample of patients previously treated for drug-sensitive TB. Interview content encompassed WHO's framework for barriers to adherence to long-term therapies and included questions about patient preferences and motivators concerning treatment adherence. We examined treatment experience across strata defined by previously identified risk correlates of non-adherence.

RESULTS

Among 60 participants, 19 (32.8%) were HIV positive, 12 (20.3%) had substance use disorder and 9 (15.0%) had not completed TB treatment. Respondents discussed the psychological distress associated with hospital-based TB care, as well as perceived unsupportive, antagonistic interactions with TB providers as major challenges to treatment adherence. An additional barrier to successful treatment completion included the financial toll of lost income during TB treatment, which was exacerbated by the additional costs of ancillary medications and transportation to ambulatory TB clinics. The high pill burden of TB treatment also undermined adherence. These challenges were endorsed among participants with and without major risk factors for non-adherence.

CONCLUSIONS

Our findings highlight important barriers to TB treatment adherence in this study population and suggest specific interventions that may be beneficial in mitigating high rates of poor treatment outcomes for TB in Ukraine.
