Social incentives for adherence to tuberculosis treatment

Medication nonadherence and associated factors in patients with tuberculosis in Wau, South Sudan: a cross- sectional study using the world health organization multidimensional adherence model

BACKGROUND

Tuberculosis medication nonadherence is a multi-dimensional public health problem with serious consequences worldwide. There is little information available for medication nonadherence in South Sudan. This study assessed the proportion, reasons, and associated factors for nonadherence among patients with TB in Wau Municipality, South Sudan.

METHODS

A health facility based cross-sectional study was conducted among 234 tuberculosis (TB) patients receiving first line anti-TB regimen in Wau Municipality. Urine isoniazid metabolite testing (IsoScreen®) was used to determine nonadherence (visualized by negative test results) and a questionnaire was used to describe the reasons for nonadherence. Modified poisson regression with robust standard errors was performed since the proportion of nonadherence was < 10%, to identify nonadherence associated factors using the WHO Multidimensional adherence model.

RESULTS

Out of 234 participants, 24.8% (95% CI, 19.2 - 30.3) were nonadherent to the TB treatment regimen. At multivariate analysis, nonadherence was significantly associated with: relief of symptoms (APR 1.93, 95% CI 1.12 - 3.34, p = 0.018), alcohol use (APR 2.12, 95% CI 1.33 - 3.96, p = 0.019) and waiting time to receive drugs (APR 1.77, 95% CI 1.11 - 2.83, p = 0.017).

CONCLUSION

Tuberculosis medication nonadherence was high, and it's associated with patients' relived of symptoms, alcohol use, and prolonged waiting time at health facility. Hence, addressing these barriers and the use of multifaceted interventions e.g. counseling, health education and improve appointments are crucial to reduce nonadherence among patients with TB in South Sudan.

Factors associated with loss to follow-up in tuberculosis treatment in Brazil: a retrospective cohort study

OBJECTIVE

To analyze the factors associated with loss to follow-up in tuberculosis cases among adults in Brazil in 2020 and 2021.

METHOD

Retrospective cohort with secondary data from the Brazilian Notifiable Diseases Information System. A total of 24,344 people diagnosed with tuberculosis whose information was complete in the database were included. Adjusted odds ratios and confidence intervals were estimated by binary logistic regression.

RESULTS

Higher odds of loss to follow-up were observed for males, non-white ethnicity/color, with lower education level, homeless or deprived of liberty, who used drugs, alcohol and/or tobacco, with admission due to recurrence or re-entry after abandonment, and with unknown or positive serology for HIV. On the other hand, older age, extrapulmonary tuberculosis, deprivation of libertyand supervised treatment were associated with lower odds of loss to follow-up.

CONCLUSION

Demographic, socioeconomic and clinical-epidemiological factors were associated with the loss to follow-up in tuberculosis cases, which reiterates the various vulnerabilities intertwined with the illness and treatment of this disease. Therefore, there is a need to promote strategies aimed at adherence and linkage to the care for groups most vulnerable to loss to follow-up in tuberculosis treatment in Brazil.

Social protection as a right of people affected by tuberculosis: a scoping review and conceptual framework

BACKGROUND

Tuberculosis is an infectious disease strongly influenced by social determinants closely associated with cycles of poverty and social exclusion. Within this context, providing social protection for people affected by the disease constitutes a powerful instrument for reducing inequalities and enhancing inclusion and social justice. This study aimed to identify and synthesize strategies and measures aimed at ensuring social protection as a right of people affected by tuberculosis.

METHODS

This is a scoping review, with searches conducted in six databases in February 2023. We included publications from 2015 onwards that elucidate strategies and measures of social protection aimed at safeguarding the rights to health, nutrition, employment, income, housing, social assistance, and social security for people affected by tuberculosis. These strategies could be implemented through policies, programs, and/or governmental agreements in any given context. The data extracted from the articles underwent descriptive analysis and a narrative synthesis of findings based on the dimensions of social protection. Additionally, we developed a conceptual framework illustrating the organizational and operational aspects of measures and strategies related to each dimension of social protection identified in this review.

RESULTS

A total of 9317 publications were retrieved from the databases, of which sixty-three publications were included. The study's results highlighted measures and strategies concerning the social protection of people affected by tuberculosis. These measures and strategies revolved around the rights to proper nutrition and nourishment, income, housing, and health insurance, as well as expanded rights encompassing social assistance and social welfare. It was reported that ensuring these rights contributes to improving nutritional status and the quality of life for individuals with tuberculosis, along with reducing catastrophic costs, expanding access to healthcare interventions and services, and fostering TB treatment adherence, thereby leading to higher rates of TB cure.

CONCLUSIONS

Our findings identify social protection measures as a right for people affected by tuberculosis and have the potential to guide the development of evidence-based social and health policies through collaboration between tuberculosis control programs and governmental entities.

Trends in tuberculosis incidence and mortality coefficients in Brazil, 2011-2019: analysis by inflection points

Objective

To analyze the temporal trend of tuberculosis incidence and mortality rates in Brazil between 2011 and 2019.

Methods

This was an ecological time series study of tuberculosis incidence and mortality rates in Brazil between 2011 and 2019. Data were extracted from the Notifiable Disease Information System and the Mortality Information System, and population estimates were from the Brazilian Institute of Geography and Statistics. Trends were analyzed by Joinpoint regression, which recognizes inflection points for temporal analysis.

Results

The average incidence rate of tuberculosis in Brazil in the period was 35.8 cases per 100 000 population. From 2011 to 2015, this coefficient had an annual percentage change of -1.9% (95% CI [-3.4, -0.5]) followed by an increase of 2.4% (95% CI [0.9, 3.9]) until 2019. The average mortality rate between 2011 and 2019 was 2.2 deaths per 100 000 population, with an average annual percentage change of -0.4% (95% CI [-1.0, 0.2]). Amazonas was the only state with an increase in the annual average percentage variation for the incidence rate (3.2%; 95% CI [1.3, 5.1]) and mortality rate (2.7%; 95% CI [1.0, 4.4]) over the years, while Rio de Janeiro state had an increasing inflection for incidence from 2014 to 2019 (2.4%; 95% CI [1.4, 3.5]) and annual average of decreasing percentage variation (-3.5%; 95% CI [-5.0, -1.9]).

Conclusions

During the period analyzed, a decreasing trend in incidence was observed between 2011 and 2015, and an increasing trend for the period from 2015 to 2019. On the other hand, no change in the trend for mortality was found in Brazil.

Health care for people with tuberculosis/HIV co-infection from the multidisciplinary team's perspective

OBJECTIVE

to know the multidisciplinary team's perspective about the health care of people with tuberculosis and human immunodeficiency virus co-infection in relation to treatment.

METHODS

this is a descriptive-exploratory study, with a qualitative approach, carried out in a health care service in São Paulo, from May to June 2019. Semi-structured interviews were conducted with nine professionals from the multidisciplinary team. Data were processed through discourse analysis with the support of webQDA.

RESULTS

Two empirical categories emerged: Health care interfaces for people with tuberculosis and human immunodeficiency virus co-infection; Barriers and facilitators for health care for people with co-infection.

FINAL CONSIDERATIONS

the health-disease process in co-infection is mediated by conditions that positively or negatively interfere with treatment compliance. People's health care goes beyond exclusively clinical assistance and requires the recognition of needs in a broad perspective.

Psychosocial support interventions to improve treatment outcomes for people living with tuberculosis: a mixed methods systematic review and meta-analysis

Background

People with tuberculosis (TB) face multi-dimensional barriers when accessing and engaging with care. There is evidence that providing psychosocial support within people-centered models of care can improve TB outcomes, however, there is limited consensus on what works. It remains important for such interventions to be rigorously assessed, and mixed methods systematic reviews are one way of synthesising data for policy makers to be able to access such evidence. Mixed methods reviews take a complexity perspective, with qualitative data being used to contextualise the quantitative findings and giving an insight into how interventions are contingent on variations in design and context.

Methods

Five electronic databases were searched from January 1 2015 to 14 January 2023 for randomised controlled trials, quasi-experimental trials, cohort studies and qualitative studies of interventions providing psychosocial support (material and/or psychological-based support) to adults with any clinical form of active TB. Studies with inpatient treatment as the standard of care were excluded. Quantitative studies reporting pre-specified standard TB outcomes were eligible. In line with established mixed methods review methodology, a convergent parallel-results synthesis design was followed: quantitative and qualitative syntheses were distinct and carried out using appropriate methods. A convergent coding matrix was then used to integrate the results. The protocol was registered on PROSPERO (CRD42021235211).

Findings

Twenty-three studies of interventions were included (12 quantitative, 10 qualitative, and 1 mixed methods study) were included. Most studies were conducted in low-and middle-income countries with a high-burden of TB. Three explanatory and contextual middle-range theories from the integration of qualitative and quantitative data were developed: effective interventions provide multi-dimensional support; psychological-based support is transformative but there is insufficient evidence that it improves treatment outcomes on its own; intervention delivery shapes a logic of care.

Interpretation

This review takes a complexity perspective to provide actionable and timely insight to inform the design and implementation of locally-appropriate and people-centered psychosocial support interventions within national TB programmes.

Funding

There was no funding source for this study.

Time Trend Analysis of Tuberculosis Treatment While Using Digital Adherence Technologies-An Individual Patient Data Meta-Analysis of Eleven Projects across Ten High Tuberculosis-Burden Countries

Worldwide, non-adherence to tuberculosis (TB) treatment is problematic. Digital adherence technologies (DATs) offer a person-centered approach to support and monitor treatment. We explored adherence over time while using DATs. We conducted a meta-analysis on anonymized longitudinal adherence data for drug-susceptible (DS) TB (n = 4515) and drug-resistant (DR) TB (n = 473) populations from 11 DAT projects. Using Tobit regression, we assessed adherence for six months of treatment across sex, age, project enrolment phase, DAT-type, health care facility (HCF), and project. We found that DATs recorded high levels of adherence throughout treatment: 80% to 71% of DS-TB patients had ≥90% adherence in month 1 and 6, respectively, and 73% to 75% for DR-TB patients. Adherence increased between month 1 and 2 (DS-TB and DR-TB populations), then decreased (DS-TB). Males displayed lower adherence and steeper decreases than females (DS-TB). DS-TB patients aged 15−34 years compared to those >50 years displayed steeper decreases. Adherence was correlated within HCFs and differed between projects. TB treatment adherence decreased over time and differed between subgroups, suggesting that over time, some patients are at risk for non-adherence. The real-time monitoring of medication adherence using DATs provides opportunities for health care workers to identify patients who need greater levels of adherence support.

Exercise of rights of tuberculosis patients undergoing pharmacological treatment

OBJECTIVES

to know how people with tuberculosis undergoing treatment exercise their rights throughout daily life while experiencing illness.

METHODS

this qualitative study was developed from April to May 2015, with people with tuberculosis undergoing treatment in an outpatient clinic of the Municipal Tuberculosis Control Program in the city of Pelotas. Data were collected through semi-structured interviews and verified by content analysis, under the thematic modality.

RESULTS

people announced aspects that involved human rights pertaining to their experiences, and they had difficulties to achieve full rights to dignity, health, social security, and social services. Such rights were neither guaranteed by the State nor by their families.

FINAL CONSIDERATIONS

it is necessary for health professionals and services to inform and equip people with tuberculosis, directly or indirectly, for the full exercise of their rights.

The effects of family, society and national policy support on treatment adherence among newly diagnosed tuberculosis patients: a cross-sectional study

Background

Non-adherence to tuberculosis (TB) treatment is the most important cause of poor TB outcomes, and improving support for TB patients is a primary priority for governments, but there has been little research on the effects of family, social and national policy support factors on TB treatment adherence. The current study evaluated treatment adherence among newly diagnosed TB patients in Dalian, north-eastern China, and determined the effects of family, society, and national policy support factors on treatment adherence.

Methods

A cross-sectional survey was conducted among newly diagnosed TB patients treated at the outpatient department of Dalian Tuberculosis Hospital from September 2019 to January 2020. Data were collected using a questionnaire that measured medication adherence, family support, social support, and national policy support and so on. Differences between groups were assessed using Chi-square tests and Fisher’s exact tests. Ordinal logistic regression analysis was used to determine the predictors of adherence.

Results

A total of 481 newly diagnosed TB patients were recruited, of whom 45.7% had good adherence, and 27.4 and 26.8% had moderate and low adherence, respectively. Patients who had family members who frequently supervised medication (OR:0.34, 95% CI:0.16–0.70), family members who often provided spiritual encouragement (OR:0.13, 95% CI:0.02–0.72), a good doctor-patient relationship (OR:0.61, 95% CI:0.40–0.93), more TB-related knowledge (OR:0.49, 95% CI:0.33–0.72) and a high need for TB treatment policy support (OR:0.38, 95% CI:0.22–0.66) had satisfactory medication adherence. However, patients who had a college degree or higher (OR:1.69, 95% CI:1.04–2.74) and who suffered adverse drug reactions (OR:1.45, 95% CI:1.00–2.11) were more likely to have lower adherence.

Conclusions

Our findings suggested that non-adherence was high in newly diagnosed TB patients. Patients who had family members who frequently supervised medication and provided spiritual encouragement and a good doctor-patient relationship and TB-related knowledge and a high need for policy support contributed to high adherence. It is recommended to strengthen medical staff training and patient and family health education and to increase financial support for improving adherence.

Estigma, prejuicio y adhesión al tratamiento: representaciones sociales de personas con tuberculosis

Introducción: La tuberculosis es una enfermedad marcada por estigmas, tabúes y creencias que afectan a las personas por la posibilidad de experimentar prejuicios. Este estudio tuvo como objetivo analizar las representaciones sociales de los sujetos afectados por la tuberculosis sobre la experiencia de prejuicio y estigma relacionados con la enfermedad. Materiales y Métodos: Estudio exploratorio, descriptivo con enfoque cualitativo. La población estaba compuesta por individuos diagnosticados con tuberculosis, residentes en la ciudad de Cajazeiras - PB, y la muestra consistió en siete sujetos. Los datos se obtuvieron mediante entrevistas semiestructuradas con datos de identificación y preguntas sobre la representación social de la tuberculosis. Los resultados se consideraron a través del análisis de contenido temático, a la luz de la Teoría de las Representaciones Sociales. Resultados: Se identificó la formulación de las siguientes categorías temáticas: vivir con tuberculosis: concepciones sobre la enfermedad; el contexto familiar y social; el dolor que más duele: el alejamiento; el tratamiento y sus dimensiones particulares; el apoyo o falta de este por parte de los servicios de salud. Discusión: El estigma y la discriminación contribuyen a una mala adhesión al tratamiento de la tuberculosis. Conclusiones: El éxito en el tratamiento de enfermedades desatendidas, transmisibles y sujetas a prejuicios, como la tuberculosis, depende en parte de cómo los individuos afectados sean acogidos en la convivencia familiar y social, y por los profesionales de la salud durante el diagnóstico y tratamiento.
