Non-adherence of new pulmonary tuberculosis patients to anti-tuberculosis treatment

Effectiveness of nutritional support to improve treatment adherence in patients with tuberculosis: a systematic review

CONTEXT

Nutritional interventions substantially improve tuberculosis (TB) treatment outcomes and prevent complications. However, there is limited evidence about the connections between having nutritional support and TB treatment adherence.

OBJECTIVE

The aim of this study was to determine the effectiveness of nutritional support in improving treatment adherence among patients with TB.

DATA SOURCES

Databases, including PubMed, Embase (Ovid), Web of Science, and Scopus, were comprehensively reviewed to identify relevant studies reporting the impacts of nutritional support on TB treatment adherence.

DATA EXTRACTION

Two authors independently screened the title, abstracts, and full article texts to identify eligible studies and assess the risk of bias. Observational and interventional studies were included.

DATA ANALYSIS

A narrative synthesis approach was used to summarize the findings qualitatively.

RESULTS

From the search, 3059 publications were identified; of these, 8 studies were included in this systematic review. Three types of nutritional interventions were identified: food baskets (eg, energy, micronutrient- or macronutrient-enriched food support), nutritional advice and guidance, and incentives for buying foods. Although 5 studies reported that nutritional support significantly improved treatment adherence in patients with TB, 3 studies showed that nutritional support had no effect on TB treatment adherence.

CONCLUSIONS

Providing nutritional support may improve adherence to TB treatment. However, more well-powered, high-quality trials are warranted to demonstrate the effect of nutrition support on cost-effectively improving adherence to TB treatment.

Acceptability of a Digital Adherence Tool Among Patients With Tuberculosis and Tuberculosis Care Providers in Kilimanjaro Region, Tanzania: Mixed Methods Study

BACKGROUND

The World Health Organization has recommended digital adherence tools (DATs) as a promising intervention to improve antituberculosis drug adherence. However, the acceptability of DATs in resource-limited settings is not adequately studied.

OBJECTIVE

We investigated the acceptability of a DAT among patients with tuberculosis (TB) and TB care providers in Kilimanjaro, Tanzania.

METHODS

We conducted a convergent parallel mixed methods study among patients with TB and TB care providers participating in our 2-arm cluster randomized trial (REMIND-TB). The trial aimed to investigate whether the evriMED pillbox with reminder cues and adherence feedback effectively improves adherence to anti-TB treatment among patients with TB in Kilimanjaro, Tanzania. We conducted exit and in-depth interviews among patients as well as in-depth interviews among TB care providers in the intervention arm. We conducted a descriptive analysis of the quantitative data from exit interviews. Translated transcripts and memos were organized using NVivo software. We employed inductive and deductive thematic framework analysis, guided by Sekhon's theoretical framework of acceptability.

RESULTS

Out of the 245 patients who completed treatment, 100 (40.8%) were interviewed during exit interviews, and 18 patients and 15 TB care providers were interviewed in-depth. Our findings showed that the DAT was highly accepted: 83% (83/100) expressed satisfaction, 98% (98/100) reported positive experiences with DAT use, 78% (78/100) understood how the intervention works, and 92% (92/100) successfully used the pillbox. Good perceived effectiveness was reported by 84% (84/100) of the participants who noticed improved adherence, and many preferred continuing receiving reminders through SMS text messages, indicating high levels of self-efficacy. Ethical concerns were minimal, as 85 (85%) participants did not worry about remote monitoring. However, some participants felt burdened using DATs; 9 (9%) faced difficulties keeping the device at home, 12 (12%) were not pleased with receiving daily reminder SMS text messages, and 30 (30%) reported challenges related to mobile network connectivity issues. TB care providers accepted the intervention due to its perceived impact on treatment outcomes and behavior change in adherence counseling, and they demonstrated high level of intervention coherence.

CONCLUSIONS

DATs are highly acceptable in Tanzania. However, some barriers such as TB-related stigma and mobile network connectivity issues may limit acceptance.

Barriers to engagement in the care cascade for tuberculosis disease in India: A systematic review of quantitative studies

BACKGROUND

India accounts for about one-quarter of people contracting tuberculosis (TB) disease annually and nearly one-third of TB deaths globally. Many Indians do not navigate all care cascade stages to receive TB treatment and achieve recurrence-free survival. Guided by a population/exposure/comparison/outcomes (PECO) framework, we report findings of a systematic review to identify factors contributing to unfavorable outcomes across each care cascade gap for TB disease in India.

METHODS AND FINDINGS

We defined care cascade gaps as comprising people with confirmed or presumptive TB who did not: start the TB diagnostic workup (Gap 1), complete the workup (Gap 2), start treatment (Gap 3), achieve treatment success (Gap 4), or achieve TB recurrence-free survival (Gap 5). Three systematic searches of PubMed, Embase, and Web of Science from January 1, 2000 to August 14, 2023 were conducted. We identified articles evaluating factors associated with unfavorable outcomes for each gap (reported as adjusted odds, relative risk, or hazard ratios) and, among people experiencing unfavorable outcomes, reasons for these outcomes (reported as proportions), with specific quality or risk of bias criteria for each gap. Findings were organized into person-, family-, and society-, or health system-related factors, using a social-ecological framework. Factors associated with unfavorable outcomes across multiple cascade stages included: male sex, older age, poverty-related factors, lower symptom severity or duration, undernutrition, alcohol use, smoking, and distrust of (or dissatisfaction with) health services. People previously treated for TB were more likely to seek care and engage in the diagnostic workup (Gaps 1 and 2) but more likely to suffer pretreatment loss to follow-up (Gap 3) and unfavorable treatment outcomes (Gap 4), especially those who were lost to follow-up during their prior treatment. For individual care cascade gaps, multiple studies highlighted lack of TB knowledge and structural barriers (e.g., transportation challenges) as contributing to lack of care-seeking for TB symptoms (Gap 1, 14 studies); lack of access to diagnostics (e.g., X-ray), non-identification of eligible people for testing, and failure of providers to communicate concern for TB as contributing to non-completion of the diagnostic workup (Gap 2, 17 studies); stigma, poor recording of patient contact information by providers, and early death from diagnostic delays as contributing to pretreatment loss to follow-up (Gap 3, 15 studies); and lack of TB knowledge, stigma, depression, and medication adverse effects as contributing to unfavorable treatment outcomes (Gap 4, 86 studies). Medication nonadherence contributed to unfavorable treatment outcomes (Gap 4) and TB recurrence (Gap 5, 14 studies). Limitations include lack of meta-analyses due to the heterogeneity of findings and limited generalizability to some Indian regions, given the country's diverse population.

CONCLUSIONS

This systematic review illuminates common patterns of risk that shape outcomes for Indians with TB, while highlighting knowledge gaps-particularly regarding TB care for children or in the private sector-to guide future research. Findings may inform targeting of support services to people with TB who have higher risk of poor outcomes and inform multicomponent interventions to close gaps in the care cascade.

Change in psychological parameters and quality of life among individuals with pulmonary and extrapulmonary tuberculosis following the intensive phase of therapy: A longitudinal observational study from central India

BACKGROUND

Tuberculosis (TB) is a global health concern, impacting millions annually, with limited attention to the psychological distress it inflicts. Psychological comorbidities, such as depression, anxiety, and stress, significantly affect the quality of life (QoL) of TB patients. Available literature on this topic is restricted to the pulmonary TB (PTB) patients; while psychological issues of the extrapulmonary TB (EPTB) patients who comprise a significant proportion of this disease entity remains unexplored. Additionally, the impact of anti-TB treatment on psychological parameters has received limited attention and vice-versa. This study aimed to assess depression, anxiety, stress, and QoL of TB patients at diagnosis and to understand how these parameters change after the intensive phase of treatment.

METHODS

A longitudinal observational study involving 40 TB patients (31 EPTB and 9 TB) was conducted to assess depression, anxiety, stress and QoL among them. Participants were followed up after the intensive treatment phase.

RESULTS

At baseline, 32.5% (n = 13) and 65% (n = 26) participants experienced moderate-severe depression, and moderate-severe anxiety, and stress, respectively. QoL was notably compromised, especially in the psychological domain. Post-intensive treatment, anxiety and depression showed significant improvement (Z = -2.271, p = 0.023 and Z = -2.093, p = 0.036), but QoL and stress levels remained largely unchanged (p > 0.05).

CONCLUSION

This study highlights the high prevalence of psychological distress and poor QoL among TB patients. Following intensive phase of therapy, severity of depression and anxiety reduced significantly; however, change in stress-level and QoL was non-significant. Although study is limited by in terms for small sample size, the need of holistic, multidisciplinary treatment approach (including mental health professionals) for such patients can't be overemphasized. Implementing baseline psychological screenings and providing mental health support if required, are critical to improve the overall health and QoL of these individuals.

Socio-demographic factors & adherence of newly diagnosed pulmonary tuberculosis patients to the newly introduced daily regimen: A hospital survey based follow up study

INTRODUCTION

Poor adherence to anti-tuberculosis medication is a major barrier to its global control. Patient adherence to the standard anti-TB therapy (ATT) in developing countries has been estimated to be as low as 40%. Multiple factors influencing adherence to treatment are: Economic and structural factors such as homelessness, unemployment and poverty; patient related factors like ethnicity, gender, age, knowledge about TB, cultural belief systems, mental state etc. AIMS & OBJECTIVES: This study was planned with the aim to study the association between various socio-demographic factors with level of adherence to the daily regimen amongst newly diagnosed pulmonary TB patients at a tertiary care hospital in metropolitan city of Maharashtra. Additionally, we tried to determine the type of non-adherence along with reasons for it.

METHOD

ology: An interview based pre-tested and validated questionnaire was developed & used as data collection tool. Total 181 newly diagnosed, FDC naïve, drug sensitive pulmonary TB patients from DOT center of a tertiary care hospital were enrolled & interviewed for sociodemographic, treatment & adherence details. They were followed up at 2nd & 6th month of their treatment, i.e., IP & CP follow up. Their Nikshay portal data & TB treatment cards were accessed for information on treatment adherence.

RESULTS

Out of 181 patients, 110 (60.8%) were found to be adherent whereas 71 (39.2%) were found to be non-adherent. Among those non-adherent, 64 (90.9%) had treatment gaps (intermittent missed doses) & 7 (9.9%) showed discontinuation of treatment. Majority of these patients reported personal obligations & starting to feel better as the main reason for non-adherence (p < 0.0001). The sociodemographic factors that had significant impact on level of adherence were patients' age (p = 0.013); level of education (p = 0.035); family size (p = 0.018); family history of TB (p = 0.0001) & current smoking habit (p = 0.025).

CONCLUSION

It is evident from the study that socio-demographic factors do have a major impact on patients' levels of adherence to treatment. Family history of TB as well as sputum conversion at end of treatment/CP have been identified as independent risk factors among pulmonary TB patients who are non-adherent to treatment. Thus, ensuring robust availability of DBT & intensive tobacco cessation sessions for all diagnosed patients as well as strengthening system for making prophylaxis available for household & close contacts of patients can help in reducing impact of socio-demographic factors & improving adherence levels.

RECOMMENDATIONS

In-patient care option specifically during IP; regular dietary counseling to improve nutrition & help reduce drug side effects & use of alternate adherence technologies like facility-based DOT or Video Observed Therapy (VOT) wherever feasible can help to improve adherence levels for TB patients from all walks of life.

Adaptive evaluation of mHealth and conventional adherence support interventions to optimize outcomes with new treatment regimens for drug-resistant tuberculosis and HIV in South Africa (ADAP-TIV): study protocol for an adaptive randomized controlled trial

BACKGROUND

Highly effective, short-course, bedaquiline-containing treatment regimens for multidrug-resistant tuberculosis (MDR-TB) and integrase strand transfer inhibitor (INSTI)-containing fixed dose combination antiretroviral therapy (ART) have radically transformed treatment for MDR-TB and HIV. However, without advances in adherence support, we may not realize the full potential of these therapeutics. The primary objective of this study is to compare the effect of adherence support interventions on clinical and biological endpoints using an adaptive randomized platform.

METHODS

This is a prospective, adaptive, randomized controlled trial comparing the effectiveness of four adherence support strategies on a composite clinical outcome in adults with MDR-TB and HIV initiating bedaquiline-containing MDR-TB treatment regimens and receiving ART in KwaZulu-Natal, South Africa. Trial arms include (1) enhanced standard of care, (2) psychosocial support, (3) mHealth using cellular-enabled electronic dose monitoring, and (4) combined mHealth and psychosocial support. The level of support will be titrated using a differentiated service delivery (DSD)-informed assessment of treatment support needs. The composite primary outcome will include survival, negative TB culture, retention in care, and undetectable HIV viral load at month 12. Secondary outcomes will include individual components of the primary outcome and quantitative evaluation of adherence on TB and HIV treatment outcomes.

DISCUSSION

This trial will evaluate the contribution of different modes of adherence support on MDR-TB and HIV outcomes with WHO-recommended all-oral MDR-TB regimens and ART in a high-burden operational setting. We will also assess the utility of a DSD framework to pragmatically adjust levels of MDR-TB and HIV treatment support.

Nonadherence to anti-tuberculosis treatment, reasons and associated factors among pulmonary tuberculosis patients in the communities in Indonesia

BACKGROUND

Tuberculosis (TB) is the world's major public health problem. We assessed the proportion, reasons, and associated factors for anti-TB treatment nonadherence in the communities in Indonesia.

METHODS

This national coverage cross-sectional survey was conducted from 2013 to 2014 with stratified multi-stage cluster sampling. Based on the region and rural-urban location. The 156 clusters were distributed in 136 districts/cities throughout 33 provinces, divided into three areas. An eligible population of age ≥15 was interviewed to find TB symptoms and screened with a thorax x-ray. Those whose filtered result detected positive followed an assessment of Sputum microscopy, LJ culture, and Xpert MTB/RIF. Census officers asked all participants about their history of TB and their treatment-defined Nonadherence as discontinuation of anti-tuberculosis treatment for <6 months. Data were analyzed using STATA 14.0 (College Station, TX, USA).

RESULTS

Nonadherence to anti-TB treatment proportion was 27.24%. Multivariate analysis identified behavioral factors significantly associated with anti-TB treatment nonadherence, such as smoking (OR = 1.78, 95% CI (1.47-2.16)); place of first treatment received: government hospital (OR = 1.45, 95% CI:1.06-1.99); private hospital (OR = 1.93, 95% CI: 1.38-2.72); private practitioner (OR = 2.24, 95% CI: 1.56-3.23); socio-demographic and TB status included region: Sumatera (OR = 1.44, 95% CI: 1.05-1.98); other areas (OR = 1.84, 95% CI: 1.30-2.61); low level of education (OR = 1.60, 95% CI: 1.27-2.03); and current TB positive status (OR = 2.17, 95% CI: 1.26-3.73).

CONCLUSIONS

Nonadherence to anti-TB drugs was highly related to the personal perception of the respondents, despite smoking, current TB status, a place for the first treatment, education, and region. The position of the first TB treatment at the private practitioner was significantly associated with the risk of Nonadherence to treatment.

A machine learning approach to explore individual risk factors for tuberculosis treatment non-adherence in Mukono district

Despite the availability and implementation of well-known efficacious interventions for tuberculosis treatment by the Ministry of Health, Uganda (MoH), treatment non-adherence persists. Moreover, identifying a specific tuberculosis patient at risk of treatment non-adherence is still a challenge. Thus, this retrospective study, based on a record review of 838 tuberculosis patients enrolled in six health facilities, presents, and discusses a machine learning approach to explore the individual risk factors predictive of tuberculosis treatment non-adherence in the Mukono district, Uganda. Five classification machine learning algorithms, logistic regression (LR), artificial neural networks (ANN), support vector machines (SVM), random forest (RF), and AdaBoost were trained, and evaluated by computing their accuracy, F1 score, precision, recall, and the area under the receiver operating curve (AUC) through the aid of a confusion matrix. Of the five developed and evaluated algorithms, SVM (91.28%) had the highest accuracy (AdaBoost, 91.05% performed better than SVM when AUC is considered as evaluation parameter). Looking at all five evaluation parameters globally, AdaBoost is quite on par with SVM. Individual risk factors predictive of non-adherence included tuberculosis type, GeneXpert results, sub-country, antiretroviral status, contacts below 5 years, health facility ownership, sputum test results at 2 months, treatment supporter, cotrimoxazole preventive therapy (CPT) dapsone status, risk group, patient age, gender, middle and upper arm circumference, referral, positive sputum test at 5 and 6 months. Therefore, machine learning techniques, specifically classification types, can identify patient factors predictive of treatment non-adherence and accurately differentiate between adherent and non-adherent patients. Thus, tuberculosis program management should consider adopting the classification machine learning techniques evaluated in this study as a screening tool for identifying and targeting suited interventions to these patients.

Improving treatment adherence among tuberculosis patients through evening DOTS in Chennai, India

Background Fixed days and timings of service are challenges in the care of patients with tuberculosis (TB). We assessed whether provision of evening DOTS (directly observed treatment, short course) improves treatment outcomes in a city with a working population. Methods We enrolled new adult patients with TB from seven tuberculous units (TUs) in this prospective cohort study. Participants were offered the option of DOTS during the day (8 a.m. to 3:30 p.m.) or evening (4 p.m. to 8 p.m.) and assigned accordingly. Results Of 127 patients enrolled between April and July 2017, 19 (15%) opted for evening DOTS. The number varied between the seven TUs (p=0.002). On an average, antitubercular therapy (ATT) was taken at 9:41 a.m. in the routine and 5:14 p.m. in the evening DOTS centres. Patients who were employed, left residence and returned back at 9:05 a.m. and 6:40 p.m., respectively. Around 96% (104/108) opted for day-time DOTS due to closeness of the centre to their residence. Around 74% (14/19) chose evening DOTS because of time convenience. Around 15% of patients on routine DOTS (16) had unfavourable treatment outcomes. All had favourable outcomes in the evening DOTS. Men were less likely and those withut alcohol disorders were more likely to have treatment success. Conclusion Provision of time convenient services might improve adherence and treatment outcome.

The Dysbiosis Triggered by First-Line Tuberculosis Antibiotics Fails to Reduce Their Bioavailability

Antituberculosis therapy (ATT) causes a rapid and distinct alteration in the composition of the intestinal microbiota that is long lasting in both mice and humans. This observation raised the question of whether such antibiotic-induced changes in the microbiome might affect the absorption or gut metabolism of the tuberculosis (TB) drugs themselves. To address this issue, we utilized a murine model of antibiotic-induced dysbiosis to assay the bioavailability of rifampicin, moxifloxacin, pyrazinamide, and isoniazid in mouse plasma over a period of 12 h following individual oral administration. We found that 4-week pretreatment with a regimen of isoniazid, rifampicin, and pyrazinamide (HRZ), a drug combination used clinically for ATT, failed to reduce the exposure of any of the four antibiotics assayed. Nevertheless, mice that received a pretreatment cocktail of the broad-spectrum antibiotics vancomycin, ampicllin, neomycin, and metronidazole (VANM), which are known to deplete the intestinal microbiota, displayed a significant decrease in the plasma concentration of rifampicin and moxifloxacin during the assay period, an observation that was validated in germfree animals. In contrast, no major effects were observed when similarly pretreated mice were exposed to pyrazinamide or isoniazid. Thus, the data from this animal model study indicate that the dysbiosis induced by HRZ does not reduce the bioavailability of the drugs themselves. Nevertheless, our observations suggest that more extreme alterations of the microbiota, such as those occurring in patients on broad-spectrum antibiotics, could directly or indirectly affect the exposure of important TB drugs and thereby potentially influencing treatment outcome. IMPORTANCE Previous studies have shown that treatment of Mycobacterium tuberculosis infection with first-line antibiotics results in a long-lasting disruption of the host microbiota. Since the microbiome has been shown to influence the host availability of other drugs, we employed a mouse model to ask whether the dysbiosis resulting from either tuberculosis (TB) chemotherapy or a more aggressive course of broad-spectrum antibiotics might influence the pharmacokinetics of the TB antibiotics themselves. While drug exposure was not reduced in animals previously described as exhibiting the dysbiosis triggered by conventional TB chemotherapy, we found that mice with other alterations in the microbiome, such as those triggered by more intensive antibiotic treatment, displayed decreased availability of rifampicin and moxifloxacin, which in turn could impact their efficacy. The above findings are relevant not only to TB but also to other bacterial infections treated with these two broader spectrum antibiotics.

Prevalence and predictive factors of tuberculosis treatment interruption in the Asia region: a systematic review and meta-analysis

INTRODUCTION

Tuberculosis (TB) treatment interruption remains a critical challenge leading to poor treatment outcomes. Two-thirds of global new TB cases are mostly contributed by Asian countries, prompting systematic analysis of predictors for treatment interruption due to the variable findings.

METHODS

Articles published from 2012 to 2021 were searched through seven databases. Studies that established the relationship for risk factors of TB treatment interruption among adult Asian were included. Relevant articles were screened, extracted and appraised using Joanna Briggs Institute's checklists for cohort, case-control and cross-sectional study designs by three reviewers. Meta-analysis was performed using the random effect model in Review Manager software. The pooled prevalence and predictors of treatment interruption were expressed in ORs with 95% CIs; heterogeneity was assessed using the I2 statistic. The publication bias was visually inspected using the funnel plot.

RESULTS

Fifty eligible studies (658 304 participants) from 17 Asian countries were included. The overall pooled prevalence of treatment interruption was 17% (95% CI 16% to 18%), the highest in Southern Asia (22% (95% CI 16% to 29%)), followed by Eastern Asia (18% (95% CI 16% to 20%)) and South East Asia (16% (95% CI 4% to 28%)). Seven predictors were identified to increase the risk of treatment interruption, namely, male gender (OR 1.38 (95% CI 1.26 to 1.51)), employment (OR 1.43 (95% CI 1.11 to 1.84)), alcohol intake (OR 2.24 (95% CI 1.58 to 3.18)), smoking (OR 2.74 (95% CI 1.98 to 3.78)), HIV-positive (OR 1.50 (95% CI 1.15 to 1.96)), adverse drug reactions (OR 2.01 (95% CI 1.20 to 3.34)) and previously treated cases (OR 1.77 (95% CI 1.39 to 2.26)). All predictors demonstrated substantial heterogeneity except employment and HIV status with no publication bias.

CONCLUSION

The identification of predictors for TB treatment interruption enables strategised planning and collective intervention to be targeted at the high-risk groups to strengthen TB care and control in the Asia region.

Perceptions of healthcare professionals and patients on the role of the pharmacist in TB management in Pakistan: A qualitative study

Background: Globally, tuberculosis (TB) is the second major cause of death from infectious diseases, particularly in developing countries. A multidisciplinary approach to the management of TB may help to curb the disease burden. Objective: The objective of this study was to outline the perceptions of healthcare professionals and patients regarding the potential role of pharmacists in TB management in Pakistan. Method: This was a large-scale qualitative study conducted at the Chest Disease Unit (CDU) of the Bahawal Victoria Hospital (BVH), Punjab, Pakistan. Data were collected through semi-structured interviews with physicians, pharmacists, and patients recruited using a mix of convenient and snowball sampling. The sample size was decided through standard saturation point criteria. All interviews were audio recorded and transcribed verbatim. The data were analyzed to draw conclusions using a thematic analysis approach. Results: Analysis of the data yielded 19 categories and seven themes. Physicians considered pharmacists qualified healthcare professionals, whereas patients considered them merely dispensers. Inventory management and dispensing of medicines were considered as major responsibilities of pharmacists. Physicians were extremely overburdened and wanted to delegate certain duties to pharmacists, subject to their prior extensive trainings. However, most of the physicians were unaware of the legal scope of pharmacy practice in Pakistan. With regard to the potential duties of pharmacists, physicians, pharmacists, and patients (patients-upon explaining the potential roles during the interview) endorsed monitoring, counseling, medicine brand selection, dose adjustment, inventory management, dispensing, and polypharmacy assessment as their potential roles. In view of all stakeholders, the rationale for integrating pharmacists in TB management included overburdened physicians, sub-standard patient care, medication safety issues, and patient dissatisfaction. The healthcare professionals highlighted that the major barriers to integrating pharmacists within the TB management system were limited interest of regulatory authorities and policy makers, followed by inadequate training and experience-driven questionable competency of pharmacists. Conclusion: The study participants acknowledged the potential role of pharmacists in TB management. However, it was emphasized that healthcare policy makers should devise strategies to overcome the underlying barriers before assigning medicine-related clinical roles to pharmacists.

Characteristics and Treatment Outcomes among Migrants with Pulmonary Tuberculosis: A Retrospective Cohort Study in Japan, 2009-2018

This study aimed to describe characteristics and treatment outcomes of overseas-born pulmonary tuberculosis (PTB) patients in Japan, and identify the factors associated with "treatment non-success". We conducted a retrospective analysis of overseas-born patients with drug-susceptible PTB using cohort data of PTB cases newly registered in the Japan tuberculosis (TB) surveillance system between 2009 and 2018. Overall, 9151 overseas-born PTB cases were included in this study, and 70.3% were aged 34 years old or younger. "Students of high school and higher" (28.6%) and "regular workers other than service related sectors" (28.5%) accounted for over half of the study population, and they have continued to increase. Overall, the treatment success rate was 67.1%. Transferred-out constituted the largest proportion (14.8%) among the treatment non-success rate (32.9%). Multiple logistic regression analysis revealed patients whose health insurance type was "others and unknown", including the uninsured (adjusted OR (AOR) = 3.43: 95% Confidence Intervals (CI) 2.57-4.58), those diagnosed as TB within "one year" (AOR = 2.61, 95% CI 1.97-3.46) and "1-5 years" (AOR = 2.44, 95% CI 1.88-3.17) of arrival in Japan, and males (AOR = 1.34, 95% CI 1.16-1.54), which were the main factors associated with treatment non-success. These findings imply that Japan needs to develop TB control activities considering the increasing trends of overseas-born PTB patients, the majority of whom are young and highly mobile. There is a need to pay greater attention to overseas-born PTB patients diagnosed within a short duration after entering Japan, who may be socially and economically disadvantaged for their treatment completion.

Non-adherence to anti-tubercular treatment during COVID-19 pandemic in Raipur district Central India

BACKGROUND

Non-adherence is major factor in failure of any drug regimen. The significance of non-adherence is so much that WHO states that increasing the effectiveness of Adherence Interventions may have far greater impact on health of population than any improvement in specific medical treatments. Incidence of non-adherence to Anti Tubercular Treatment (ATT) usually ranges from 8.4% to 55.8%. This study aims to find out the reasons of Non-adherence to ATT in patients receiving anti-tubercular treatment at DIRECTLY OBSERVED TREATMENT SHORTCOURSE (DOTS) Centre at District Tuberculosis Centre (DTC), Kalibadi, Raipur during COVID-19 pandemic.

METHODS

A cross sectional study was conducted at Department of Pharmacology, Pt. JNM Medical College and DTC Kalibadi Raipur. 55 Patients taking ATT fulfilling inclusion and exclusion criteria were interviewed using structured questionnaire. The data obtained was analysed to know causes of non-adherence.

RESULTS

Study was carried out between March & April 2020. In our study, 80% subjects were male and 20% were female. The main reasons for Non-adherence were Side-effects of drug in 36% cases, missing medication intentionally in 34% cases, lack of encouragement by family members in 32% cases, patient's unawareness of consequences of skipping medication in 25% cases, unaware of treatment duration in 22%, not feeling any change, forgetting to take medication, and burden of concomitant medication besides ATT, each in 20% cases, 13% cases had difficulty in procuring medication due to lockdown, 5% cases did not go to collect their medicine due to fear of contracting COVID-19 infection.

CONCLUSIONS

Our study shows reasons for Non-adherence are multi-factorial with drug side -effects & intentionally skipping medication being major factors.

Factors Influencing Treatment Adherence Among Drug-Sensitive Tuberculosis (DS-TB) Patients in Armenia: A Qualitative Study

Purpose

Despite the availability of effective treatment, tuberculosis (TB) is still one of the leading causes of mortality around the globe. Poor adherence to treatment challenges TB management both globally and locally. Proper adherence to treatment contributes to successful outcomes and prevents the development of drug-resistant forms of TB.

Patients and Methods

We conducted a qualitative study to identify and describe the factors that facilitated treatment adherence among drug-sensitive TB (DS-TB) patients in Armenia. Sixteen in-depth interviews (IDIs) with former DS-TB patients, two IDIs with family members of former DS-TB patients, and a focus group discussion with healthcare providers who manage DS-TB patients were conducted. The educational and ecological assessment component of the PRECEDE-PROCEED model was applied as a conceptual framework to guide the interview content and data analysis.

Results

Former patients' awareness of TB and its treatment, beliefs about TB, trust in TB healthcare providers, and a sense of responsibility were the most common factors that predisposed them to complete the treatment. Support received from providers, family, and friends, a desire to avoid TB-associated stigma, and good tolerance of TB medications were the main reinforcing factors. Enabling factors included a relatively simple regimen of TB treatment and accessibility and affordability of TB services.

Conclusion

The findings of the study provide new perspectives on factors that facilitate adherence to long-term therapies, such as TB. Interventions that aim to invoke a patient's sense of responsibility and positive beliefs about TB as well as engage families might promote the successful completion of treatment.

Nonadherence Predictors to Tuberculosis Medications among TB Patients in Gambella Region of Ethiopia

Background

Global tuberculosis (TB) disease deaths rise comparable to the one seen in 2015 (by 200,000) or even in 2012 (by 400,000) as a result of the potential impact of the COVID-19 pandemic. Ethiopia's Gambella region is leading for years in terms of TB cases and its comorbidities. The TB control program effectiveness depends on in large on the patients completing the appropriate treatment regimen. Hence, the objective of this study was to determine the determinants of nonadherence to anti-TB drug treatment among patients in Gambella regional state of Ethiopia.

Methods

A case-control study was conducted on cohorts of TB patients sampled from four public health facilities in Gambella Region from January 2019 to 2020, followed by 18 months of follow-up. The total sample size was 296 patients (74 cases and 222 controls) with a response rate of 97.3% (288 : 72 nonadhered cases and 216 controls). Cases (nonadhered) were TB patients who missed 10% of the doses while controls were patients, who completed 90% or more doses.

Results

TB patients, who perceived stigma [AOR = 2.7 at 95% CI (1.1–6.6) with P value <0.05], failed to receive any counseling during the treatment course [AOR = 65.24 at 95% CI (11.69–363.95) with P value <0.01], patients who used to smoking during treatment [AOR = 15.4 at 95% CI (7.7–30) with P value <0.01], taking TB medications regularly has no benefits [AOR = 6.8 at 95% CI (1.8–24.9) with P value <0.05], and patients believing TB disease as not severe [AOR = 8.38 at 95% CI (2.0–34.6) with P value <0.05] were significantly or highly significantly associated with nonadherence to anti-TB drugs medications.

Conclusion

The determinants of nonadherence to anti-TB treatment among TB patients in the Gambella region during the study period were the absence of counselling services, and patients' behavior (smoking habits, undermining the severity of TB disease, lack of trust in the outcomes of regular medications, and perceived stigmatization). Accordingly, capacitating healthcare providers and workers at all TB clinics for effective counseling , preventing perceived stigma by protecting the patient's secrecy, and routine health education has paramount importance for effective TB control in Gambella.

The Acceptability of Adherence Support via Mobile Phones for Antituberculosis Treatment in South India: Exploratory Study

BACKGROUND

India has the greatest burden of tuberculosis (TB). However, over 15% of the people on antitubercular therapy (ATT) in India are nonadherent. Several adherence monitoring techniques deployed in India to enhance ATT adherence have had modest effects. Increased adoption of mobile phones and other technologies pose potential solutions to measuring and intervening in ATT adherence. Several technology-based interventions around ATT adherence have been demonstrated in other countries.

OBJECTIVE

The objective of our study was to understand the acceptance of mobile phone adherence supports for ATT using self-administered quantitative measures among patients with TB in South India.

METHODS

This exploratory study was conducted at a TB treatment center (TTC) at a tertiary care center in Thrissur District, Kerala, India. We recruited 100 patients with TB on ATT using convenience sampling after obtaining written informed consent. Trained study staff administered the questionnaire in Malayalam, commonly spoken in Kerala, India. We used frequency, mean, median, and SD or IQR to describe the data.

RESULTS

Of the 100 participants diagnosed with TB on ATT, 90% used mobile phones routinely, and 84% owned a mobile phone. Ninety-five percent of participants knew how to use the calling function, while 65% of them did not know how to use the SMS function on their mobile phone. Overall, 89% of the participants did not consider mobile phone-based ATT adherence interventions an intrusion in their privacy, and 93% did not fear stigma if the adherence reminder was received by someone else. Most (95%) of the study participants preferred mobile phone reminders instead of directly observed treatment, short-course. Voice calls (n=80, 80%) were the more preferred reminder modality than SMS reminders (n=5, 5%).

CONCLUSIONS

Mobile phones are likely an acceptable platform to deliver ATT adherence interventions among individuals with TB in South India. Preference of voice call reminders may inform the architecture of future adherence interventions surrounding ATT in South India.

Undernutrition is feeding the tuberculosis pandemic: A perspective

Tuberculosis (TB) is a major cause of death worldwide, with 1.5 million deaths in 2020. While TB incidence and mortality had previously been on a downwards trend, in 2020, TB mortality actually rose for the first time in a decade, largely due to the COVID-19 pandemic. Undernutrition is the leading risk factor for TB, with a population attributable fraction (PAF) of 15%, compared to 7.6% for HIV. Individuals who are undernourished are more likely to develop active TB compared to those with a healthy bodyweight. They are also more likely to have greater severity of TB, and less likely to have successful TB treatment outcomes. The likelihood of TB mortality significantly increases as weight decreases. Nutritional interventions are likely to improve both nutritional status and TB treatment success, thereby decreasing TB mortality. However, many previous studies focusing on nutritional interventions have provided insufficient calories or been underpowered. Nutritional supplementation will be particularly important as factors such as the COVID-19 pandemic, climate change, and political conflict further threaten food security. The global TB elimination effort can no longer afford to ignore undernutrition.

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.

Can Self-Administered Rapid Antigen Tests (RATs) Help Rural India? An Evaluation of the CoviSelf Kit as a Response to the 2019–2022 COVID-19 Pandemic

This paper evaluates India’s first officially approved self-administered rapid antigen test kit against COVID-19, a device called CoviSelf. The context is rural India. Rapid antigen tests (RATs) are currently popular in situations where vaccination rates are low, where sections of the community remain unvaccinated, where the COVID-19 pandemic continues to grow and where easy or timely access to RTPCR (reverse transcription-polymerase chain reaction) testing is not an option. Given that rural residents make up 66% of the Indian population, our evaluation focuses on the question of whether this self-administered RAT could help protect villagers and contain the Indian pandemic. CoviSelf has two components: the test and IT (information technology) parts. Using discourse analysis, a qualitative methodology, we evaluate the practicality of the kit on the basis of data in its instructional leaflet, reports about India’s ‘digital divide’ and our published research on the constraints of daily life in Indian villages. This paper does not provide a scientific assessment of the effectiveness of CoviSelf in detecting infection. As social scientists, our contribution sits within the field of qualitative studies of medical and health problems. Self-administered RATs are cheap, quick and reasonably reliable. Hence, point-of-care testing at the doorsteps of villagers has much potential, but realising the benefits of innovative, diagnostic medical technologies requires a realistic understanding of the conditions in Indian villages and designing devices that work in rural situations. This paper forms part of a larger project regarding the COVID-19 pandemic in rural India. A follow-up study based on fieldwork is planned for 2022–2023.

'If not for this support, I would have left the treatment!': Qualitative study exploring the role of social support on medication adherence among pulmonary tuberculosis patients in Western India

Social support has been identified as a significant factor in addressing treatment barriers and facilitating treatment adherence. Using a descriptive design, this qualitative study aims at sharing personal feelings and social support-related experiences among pulmonary tuberculosis (TB) patients in Western India. A semi-structured interview guide was designed, and thirty-seven in-depth interviews were conducted. Descriptive thematic analysis was employed for reporting the themes and the results. The participants highlighted diverse social support experiences like empathy, compassion, trust, neglect, tangible aid, strained relationships with in-laws, health provider's support, strength, and motivation which influences their treatment adherent behaviour. Contrasting differences of social support experiences among adherent and non-adherent TB patients were also reported. The study has important ramifications for developing patient-centric social support intervention strategies, TB policy, and practice. The study has shown, 'if not for this support', patients would have left the treatment, and it is mainly because this debilitating disease robs people of their physical, social, economic, psychological, and emotional well-being far beyond the period when treatment is being administered. However, we resonate that addressing social support is not the only way, and TB elimination overall will require an optimal mix of enhanced biomedical, social, economic, and policy interventions.

Oral anti-tuberculosis drugs: An urgent medication reconciliation at hospitals in Indonesia

Background: Four oral anti-tuberculosis drugs are conceived to be the most effective ones to eradicate Mycobacterium tuberculosis bacteria and to obviate the resistant organisms. However, the patients’ adherence and medication discrepancies are obstacles to achieving the goal. This study aimed to define the anti-tuberculosis drugs used in the hospitals and to detect the discrepancies in the continuity of the tuberculosis treatment.

Design and Methods: This retrospective cross-sectional study was based on medical records of adult patients, and was conducted in two district tertiary care hospitals. Only 35 out of 136 patient records from Hospital A and 33 out of 85 records from Hospital B met the inclusion criteria.

Results: The most common systemic anti-infective drugs in the study were ceftriaxone (51.80 DDD/100 patient-days) used in Hospital A and isoniazid (59.53 DDD/100 patient-days) used in Hospital B. The number of rifampicin prescriptions was less than that of isoniazid. Each patient received an average of two DDD/100 patient-days, which is an under dosage for an effective treatment.

Conclusion: This study showed a medication discrepancy of tuberculosis therapy. Tuberculosis patients’ medical histories are not under the full attention of treating physicians wherever they are admitted. Thus, medication reconciliation is needed to accomplish the goal of a Tuberculosis-free world in 2050.

Adherence to TB treatment remains low during continuation phase among adult patients in Northwest Ethiopia

BACKGROUND

Patients' failure to adhere to TB treatment was a major challenge that leads to poor treatment outcomes. In Ethiopia, TB treatment success was low as compared with the global threshold. Despite various studies done in TB treatment adherence, little was known specifically in continuation phase where TB treatment is mainly patient-centered. This study aimed to determine adherence to TB treatment and its determinants among adult patients during continuation phase.

METHODS

We deployed a facility-based cross-sectional study design supplemented with qualitative data to explore perspectives of focal healthcare providers. The study population was all adult (≥18 years) TB patients enrolled in the continuation phase and focal healthcare workers in TB clinics. The study included 307 TB patients from 22 health facilities and nine TB focal healthcare providers purposively selected as key-informant. A short (11 questions) version Adherence to Refill and Medication Scale (ARMS) was used for measuring adherence. Data was collected using an interviewer-administered questionnaire and in-depth interview for qualitative data. Binary logistic regression was applied to identify factors associated with patient adherence. We followed a thematic analysis for the qualitative data. The audio data was transcribed, coded and categorized into themes using OpenCode software.

RESULTS

Among 307 participants, 64.2% (95% CI (58.6-69.4%) were adherent to TB treatment during continuation phase. A multi-variable analysis shown that secondary education (AOR = 4.138, 95% CI; 1.594-10.74); good provider-patient relationship (AOR = 1.863, 95% CI; 1.014-3.423); good knowledge on TB treatment (AOR = 1.845, 95% CI; 1.012-3.362) and middle family wealth (AOR = 2.646, 95% CI; 1.360-5.148) were significantly associated with adherence to TB treatment. The majority (58%) of patients mentioned forgetfulness, and followed by 17.3% of them traveling away from home without pills as major reasons for non-adherence to TB treatment.

CONCLUSIONS

The study indicated that patients' adherence to TB treatment remains low during continuation phase. The patient's education level, knowledge, family wealth, and provider-patient relationship were found positively associated with patient adherence. Forgetfulness, traveling away, and feeling sick were major reasons for non-adherence to TB treatment. Interventional studies are needed on those factors to improve patient adherence to TB treatment during continuation phase.

Understanding Nonadherence to Tuberculosis Medications in India Using Urine Drug Metabolite Testing: A Cohort Study

BACKGROUND

Poor adherence to tuberculosis (TB) treatment is associated with disease recurrence and death. Little research has been conducted in India to understand TB medication nonadherence.

METHODS

We enrolled adult drug-susceptible TB patients, approximately half of whom were people with human immunodeficiency virus (PWH), in Chennai, Vellore, and Mumbai. We conducted a single unannounced home visit to administer a survey assessing reasons for nonadherence and collect a urine sample that was tested for isoniazid content. We described patient-reported reasons for nonadherence and identified factors associated with nonadherence (ie, negative urine test) using multivariable logistic regression. We also assessed the association between nonadherence and treatment outcomes.

RESULTS

Of 650 participants in the cohort, 77 (11.8%) had a negative urine test. Nonadherence was independently associated with daily wage labor (adjusted odds ratio [aOR], 2.7; confidence interval [CI], 1.1-6.5; P = .03), the late continuation treatment phase (aOR, 2.0; CI, 1.1-3.9; P = .03), smear-positive pulmonary disease (aOR, 2.1; CI, 1.1-3.9; P = .03), alcohol use (aOR, 2.5; CI, 1.2-5.2; P = .01), and spending ≥30 minutes collecting medication refills (aOR, 6.6; CI, 1.5-29.5; P = .01). People with HIV reported greater barriers to collecting medications than non-PWH. Among 167 patients reporting missing doses, reported reasons included traveling from home, forgetting, feeling depressed, and running out of pills. The odds of unfavorable treatment outcomes were 4.0 (CI, 2.1-7.6) times higher among patients with nonadherence (P < .0001).

CONCLUSION

Addressing structural and psychosocial barriers will be critical to improve TB treatment adherence in India. Urine isoniazid testing may help identify nonadherent patients to facilitate early intervention during treatment.

Preference of inhalants over pills/injections among pulmonary tuberculosis patients in Western India: A cross-sectional study

•

India shares the highest burden of TB & MDR-TB cases in the world.

•

Currently, pills/injections are two modes of treatment available for TB patients.

•

Inhalants could be preferred and acceptable drug delivery method among TB patients.

•

Exploration of diverse drug delivery options for TB patients is recommended.

Background

Presently, pills and injections are the two modes of therapeutic treatment available for tuberculosis (TB) patients. Many researchers have hypothesized inhalation drug delivery for reducing treatment times and possibly limiting the insurgence of drug resistance. This study was aimed at identifying and assessing the preferences of inhalation therapy over injections/pills among pulmonary TB patients.

Method

Cross-sectional study design was used and a sample of 477 participants were recruited at selected three Directly Observed Treatment Short-Course (DOTS) centers in Bhiwandi city. Data was collected through self-reported questionnaire. Descriptive statistics were reported, and binomial regression models were applied for data analysis.

Results

The preference of inhalants over pills/injections among pulmonary TB patients was significantly associated with clinical characteristics. The patients who underwent treatment for more than 1 year were 1.7 times more likely to prefer inhalants over pills/injections when compared with treatment duration of less than 1 year. Similarly, patients taking five or more pills/day were 1.7 times more likely to prefer inhalants over pills/injections when compared with patients taking 1–4 pills per day.

Conclusion

The study results signify that inhalants could be an acceptable method of drug delivery in this population of TB patients. Diverse drug delivery options for TB patients may greatly contribute towards TB treatment adherence.

Factors influencing TB treatment interruption and treatment outcomes among patients in Kiambu County, 2016-2019

Tuberculosis (TB) is the leading cause of mortality as a single infectious agent globally with increasing numbers of case notification in developing countries. This study seeks to investigate the clinical and socio-demographic factors of time to TB treatment interruption among Tuberculosis patients in Kiambu County, 2016–2019. We retrospectively analyzed data for all treatment outcomes patients obtained from TB tracing form linked with the Tuberculosis Information Basic Unit (TIBU) of patients in Kiambu County health facilities using time to treatment interruption as the main outcome. Categorical variables were presented using frequency and percentages. Kaplan-Meir curve was used to analyze probabilities of time to treatment interruptions between intensive and continuation phases. Log-rank test statistics was used to compare the equality of the curves. Cox proportion model was used to determine determinants of treatment interruption. A total of 292 participants were included in this study. Males were 68%, with majority (35%) of the participants were aged 24–35 years; 5.8% were aged 0–14 years and 5.1% aged above 55 years. The overall treatment success rate was 66.8% (cured, 34.6%; completed 32.2%), 60.3% were on intensive phase of treatment. Lack of knowledge and relocation were the major reasons of treatment interruptions. Patients on intensive phase were 1.58 times likely to interrupt treatment compared to those on continuation phase (aHR: 1.581; 95%CI: 1.232–2.031). There is need to develop TB interventions that target men and middle aged population in order to reduce treatment interruption and increase the treatment success rates in the County and Country.

Engineered drug delivery devices to address Global Health challenges

There is a dire need for innovative solutions to address global health needs. Polymeric systems have been shown to provide substantial benefit to all sectors of healthcare, especially for their ability to extend and control drug delivery. Herein, we review polymeric drug delivery devices for vaccines, tuberculosis, and contraception.

Prevalence and associated factors for alcohol use disorder among tuberculosis patients: a systematic review and meta-analysis study

BACKGROUND

Alcohol use disorders (AUD) in tuberculosis patients are complicated with poor compliance to anti-tuberculosis treatment and poor tuberculosis treatment outcomes. However, aggregate data concerning this problem is not available. Therefore, this review aimed to fill the above gap by generating an average prevalence of AUD in tuberculosis patients.

METHOD

Our electronic search for original articles was conducted in the databases of Scopus, PubMed, and EMBASE, African Index Medicus, and psych-info. Besides, the reference list of selected articles was looked at manually to have further eligible articles for the prevalence and associated factors of AUD in tuberculosis patients. The random-effects model was employed during the analysis. MS-Excel was used to extract data and stata-11 to determine the average prevalence of AUD among tuberculosis patients. A sub-group analysis and sensitivity analysis were also run. A visual inspection of the funnel plots and an Eggers publication bias plot test were checked for the presence of publication bias.

RESULT

A search of the electronic and manual system resulted in 1970 articles. After removing duplicates and unoriginal articles, only 28 articles that studied 30,854 tuberculosis patients met the inclusion criteria. The average estimated prevalence of AUD in tuberculosis patients was 30% (95% CI: 24.00, 35.00). This was with a slight heterogeneity (I2 = 57%, p-value < 0.001). The prevalence of AUD in tuberculosis patients was higher in Asia and Europe; 37% than the prevalence in the US and Africa; 24%. Besides, the average prevalence of AUD was 39, 30, 30, and 20% in studies with case-control, cohort, cross-sectional and experimental in design respectively. Also, the prevalence of AUD was higher in studies with the assessment tool not reported (36%) than studies assessed with AUDIT. AUD was also relatively higher in studies with a mean age of ≥40 years (42%) than studies with a mean age < 40 years (24%) and mean age not reported (27%). Based on a qualitative review; the male gender, older age, being single, unemployment, low level of education and income from socio-demographic variables, retreatment and treatment failure patients, stigma, and medication non-adherence from clinical variables were among the associated factors for AUD.

CONCLUSION

This review obtained a high average prevalence of AUD in tuberculosis patients and this varies across continents, design of studies, mean age of the participants, and assessment tool used. This implied the need for early screening and management of AUD in tuberculosis patients.

Noncompliance to Directly Observed Treatment Short course in Mulshi Block, Pune District

Context:

Directly observed treatment short course (DOTS) was adopted as the strategy for the provision of treatment to increase treatment completion. Poor adherence to medication has been noted and poses a big challenge even after achieving 70% case detection and 85% cure rate. The focus remains on dealing with important reasons of default and timely retrieval of patients who interrupt the treatment.

Aims:

The aim of the study was to measure the noncompliance of DOTS and to determine the reason for the same among patients in rural area of Pune.

Materials and Methods:

An observational cross-sectional study was conducted with a study population comprising the patients who were getting treatment in November 2016 and must have completed at least 1 month of treatment in Mulshi block. The study period was from November 2016 to January 2017. All the patients were interviewed using a pretested questionnaire for their compliance.

Results:

The total number of patients included in the study was 88. The age was 18–70 years in which 77.3% were male and 22.7% were female. We found 71.6% new cases, and 27.3% were the previously treated patients, whereas 1.1% were multidrug-resistant patients. Among these patients, 25% were tobacco chewers and 31.8% were smokers. We found that 61.4% were compliance patients and 38.6% were noncompliance patients. Reasons given by the patients were side effects, stigma of the society, migration from one place to another, and felt better from symptoms after taking medication.

Conclusion:

Noncompliance in our study is high. We should take steps regarding this so that people adhere to the medication.

Treatment interruption and associated factors among patients registered on drug-resistant tuberculosis treatment in Amhara regional state, Ethiopia: 2010-2017

BACKGROUND

Drug-Resistant Tuberculosis (DR-TB) is a rising threat of the TB control program caused mainly by treatment interruption in Ethiopia. The success of the current treatment regimen for DR-TB is poor partly due to a high treatment interruption rate. Thus, this study assessed treatment interruption and associated factors among DR-TB patients.

METHODS

An institution-based cross-sectional study was conducted among 550 DR-TB patients who have initiated treatment from September 2010 to December 2017. Data were entered using Epi Data version 4.200 and exported to STATA version 14 for analysis. A bi-variable logistic regression model was first fitted, and variables having a p-value < 0.2 in the bi-variable analysis were entered into the multivariable logistic regression model. Crude and Adjusted Odds Ratios (COR and AOR) with 95% confidence interval (CI) were used to determine the strength of association between the treatment interruption and independent variables. Variables with p-value <0.05 in the multi-variable model were considered as statistically significant predictors of treatment interruption.

RESULTS

In this study, the prevalence of treatment interruption among patients registered on DR-TB treatment was 14.55% (95% CI: 11.83, 17.76). Of the interrupters, the treatment interruption during the intensive and continuation phase of treatment was reported as 45% and 71.25%, respectively. Similarly, about 15% of patients had treatment interruption both during the intensive and continuation phase of treatment. The average duration of treatment interruption was 12 (±2.03 SD) and 6 (±1.2 SD) days during the intensive and continuation phase of treatment, respectively. Patients who had no treatment supporter [AOR = 1.45; 95% CI: 1.23-3.66] and developed adverse drug events [AOR = 1.60; 95% CI: 1.22-2.85] were statistically significant predictors of treatment interruption.

CONCLUSIONS

Treatment interruption was low in the study setting. The presence of treatment supporter and absence of drug side effects was significantly associated with decreased occurrence of treatment interruption. Thus, patient linkage to treatment supporter and excellent pharmacovigilance are highly recommended in the study setting.

Catastrophic costs due to tuberculosis worsen treatment outcomes: a prospective cohort study in Indonesia

Background

While the incidence of catastrophic costs due to tuberculosis (TB) remains high, there is little evidence about their impact on TB treatment outcomes and adherence. We assessed their effect on treatment outcomes and adherence in Indonesia.

Methods

We interviewed 282 adult TB patients who underwent TB treatment in urban, suburban and rural districts of Indonesia. One year after the interview, we followed up treatment adherence and outcomes. We applied multivariable analysis using generalized linear mixed models.

Results

Follow-up was complete for 252/282 patients. Eighteen (7%) patients had unsuccessful treatment and 40 (16%) had poor adherence. At a threshold of 30% of annual household income, catastrophic costs negatively impacted treatment outcomes (adjusted odds ratio [aOR] 4.15 [95% confidence interval {CI} 1.15 to 15.01]). At other thresholds, the associations showed a similar pattern but were not statistically significant. The association between catastrophic costs and treatment adherence is complex because of reverse causation. After adjustment, catastrophic costs negatively affected treatment adherence at the 10% and 15% thresholds (aOR 2.11 [95% CI 0.97 to 4.59], p = 0.059 and aOR 2.06 [95% CI 0.95 to 4.46], p = 0.07). There was no evidence of such an effect at other thresholds.

Conclusions

Catastrophic costs negatively affect TB treatment outcomes and treatment adherence. To eliminate TB, it is essential to mitigate catastrophic costs.

Electronic medication monitor for people with tuberculosis: Implementation experience from thirty counties in China

Background

China piloted a digital adherence technology called electronic medication monitor (EMM) to support self-administered treatment for tuberculosis. EMM is a portable plastic box that records each time the device is opened, offering an indirect measure of treatment adherence. During the monthly patient visits to tuberculosis designated hospitals, the doctors access the data from the EMM.

Objectives

Among people with tuberculosis notified in 30 counties in China (July-December 2018) where EMM supported self-administered treatment was suggested to all those eligible (no communication impairment, ambulatory care), we assessed the i) proportion eligible for using EMM ii) uptake of EMM and factors associated and iii) treatment adherence, including the proportion shifted to DOT.

Methods

This was an observational study using secondary programme data. Single instance of ≥50% or continued instance of 20–49% monthly missed doses was the eligibility criteria to shift to DOT. We used log binomial regression to identify factors associated with not using EMM within first month.

Results

Of 2227 with EMM eligibility data, 1810 (81%) were eligible for EMM. Of 1810 people, 1314 (73%) ever used EMM anytime during treatment, among them, 134 (10%) were eligible for shift to DOT (based on EMM data), and 29 (22%) were shifted. In addition, 70 were shifted while the EMM data was missing. Of 1047 people who started using EMM within first month, we observed 6381 person-months of follow up and there were 1526(25%) instances of missing EMM data. Children (<15 years), elderly (≥65 years), semi-skilled or unemployed people, people with tuberculosis pleurisy and previous tuberculosis treatment were less likely to use EMM within first month.

Conclusion

The EMM uptake was satisfactory but shift to DOT has to be ensured based on adherence data from EMM. The subsequent follow-up action when EMM data is missing has to be clarified in the guidelines.

A gastric resident drug delivery system for prolonged gram-level dosing of tuberculosis treatment

Multigram drug depot systems for extended drug release could transform our capacity to effectively treat patients across a myriad of diseases. For example, tuberculosis (TB) requires multimonth courses of daily multigram doses for treatment. To address the challenge of prolonged dosing for regimens requiring multigram drug dosing, we developed a gastric resident system delivered through the nasogastric route that was capable of safely encapsulating and releasing grams of antibiotics over a period of weeks. Initial preclinical safety and drug release were demonstrated in a swine model with a panel of TB antibiotics. We anticipate multiple applications in the field of infectious diseases, as well as for other indications where multigram depots could impart meaningful benefits to patients, helping maximize adherence to their medication.

Using electronic medication monitoring to guide differential management of tuberculosis patients at the community level in China

Background

In settings such as China, where universal implementation of directly observed therapy (DOT) is not feasible, innovative approaches are needed to support patient adherence to TB treatment. The electronic medication monitor (EMM) is one of the digital technologies recommended by the World Health Organization (WHO), but evidence from implementation studies remains sparse. In this study, we evaluated acceptance of the EMM among health care workers and patients while implementing the device for differential TB patient management at the community level.

Methods

Zhenjiang City in Jiangsu Province was purposively selected for the study. All participating patients were allowed to select their preferred management approach. If patients declined to use the EMM, DOT was offered. The EMM was designed to hold 1 month of anti-TB drugs for once-daily dosing of fixed-dose combination (FDC) tablets. Patient EMM records were monitored monthly by a physician; if 20 to 50% of doses were missed twice, or more than 50% of doses were missed once, the patient was switched to DOT. The four physicians and five nurses involved in the study at four designated hospitals were surveyed using a structured questionnaire to assess their acceptance of the EMM.

Results

From October 2017 through January 2018, 316 pulmonary TB patients were notified in the TB information management system, and 231 (73.1%) met the study enrollment criteria. Although 186 patients (80.5%) initially consented to use the EMM, 17 later refused to use it. Among the 169 patients who used the EMM, 15 (8.9%) were switched to DOT due to poor adherence, and the other 154 completed the treatment course. The median adherence rate was 99.3%. Surveyed health care workers from designated hospitals found the EMM acceptable, although eight of nine felt use of the device moderately increased their workload. However, the EMM program significantly reduced the workload of community physicians by reducing patient visits by 87.9%.

Conclusions

This study demonstrated the acceptability of using an indigenously developed EMM for differential management of TB patients at the community level. However, more operational research should be conducted before introducing and scaling the technology throughout China.

Use of Smartphone-Based Video Directly Observed Therapy (vDOT) in Tuberculosis Care: Single-Arm, Prospective Feasibility Study

BACKGROUND

India accounts for nearly one-quarter of the global tuberculosis (TB) burden. Directly observed treatment (DOT) through in-person observation is recommended in India, although implementation has been heterogeneous due largely to resource limitations. Video DOT (vDOT) is a novel, smartphone-based approach that allows for remote treatment monitoring through patient-recorded videos. Prior studies in high-income, low disease burden settings, such as the United States, have shown vDOT to be feasible, although little is known about the role it may play in resource-limited, high-burden settings.

OBJECTIVE

The goal of the research was to assess the feasibility and acceptability of vDOT for adherence monitoring within a resource-limited, high TB burden setting of India.

METHODS

We conducted a prospective, single-arm, pilot implementation of vDOT in Pune, India. Outcome measures included adherence (proportion of prescribed doses observed by video) and verifiable fraction (proportion of prescribed doses observed by video or verbally confirmed with the patient following an incomplete/unverifiable video submission). vDOT acceptability among patients was assessed using a posttreatment survey.

RESULTS

A total of 25 patients enrolled. The median number of weeks on vDOT was 13 (interquartile range [IQR] 11-16). Median adherence was 74% (IQR 62%-84%), and median verifiable fraction was 86% (IQR 74%-98%). More than 90% of patients reported recording and uploading videos without difficulty.

CONCLUSIONS

We have demonstrated that vDOT may be a feasible and acceptable approach to TB treatment monitoring in India. Our work expands the evidence base around vDOT by being one of the first efforts to evaluate vDOT within a resource-limited, high TB burden setting. To our knowledge, this is the first reported use of vDOT in India.

Educational strategy intervention and remote supervision on the post-discharge management of tuberculosis diagnosed in the hospital: Randomized clinical trial

INTRODUCTION

One of the most serious problems in TB control is non-adherence to treatment leading to the risk of drug resistance and subsequent treatment failure.

OBJECTIVES

To assess the impact of an educational strategy intervention and remote supervision on the post-discharge management of new cases of TB diagnosed in hospital on TB cure rate. Secondarily, to assess the impact of this intervention on default rate.

METHODS

Randomized control trial conducted at a general, tertiary care, university affiliated hospital. New cases of TB diagnosed in hospital were included. The primary outcome was cure rate and secondary outcome was default rate. Analysis was carried out by modified intention to treat.

RESULTS

A total of 169 new tuberculosis patients were enrolled. Among them, 80 were assigned to intervention group and 89 to control group. The cure rate was 71.3% in the intervention group and 58.4% in the control group. In the multivariate binary logistic regression model to evaluate the effect of the intervention, controlled by age, sex, current smoking status and directly observed treatment short, intervention was independently associated with cure rate (OR = 0.47; 95% CI: 0.24-0.94; P = 0.033).There was a significant difference in the default rate between the control and intervention groups (18.0% vs 5.0%, respectively, P = 0.039).

CONCLUSION

An educational strategy intervention and remote supervision on the post-discharge management of new cases of TB with in-hospital diagnosis had a positive effect of small magnitude on cure rate. Secondarily, the treatment default rate has been significantly decreased with the intervention.

Factors associated with non-adherence during tuberculosis treatment among patients treated with DOTS strategy in Jayapura, Papua Province, Indonesia

BACKGROUND

Despite the implementation of Directly Observed Treatment Short-course (DOTS) strategy in all public health centers in Papua Province, Indonesia, since 1998, the rate of loss to follow-up (LTFU) during tuberculosis (TB) treatment remains high (above 16%).

OBJECTIVES

We aimed to identify factors associated with non-adherence during TB treatment among patients treated at public health centers (PHCs) in Jayapura, Papua.

METHOD

We conducted a case-control study including new TB patients registered at eight PHCs from 2007 to 2009. Non-adherent cases were TB patients with a history of not taking anti-TB drugs for >2 consecutive weeks or >30 days cumulatively. Controls were randomly selected from patients who completed all doses of TB drugs in time. Data were collected by face-to-face interview using a pre-structured questionnaire and analyzed with logistic regression models.

RESULTS

Data were available for 81 of 103 eligible cases and 183 of 206 eligible controls. Difficult access to healthcare (i.e. reported to have a problem with distance/travel cost and history of moving residence in the past year), lack of TB knowledge (i.e. lack of knowledge about TB transmission and the cause of TB and unawareness of the consequences of stopping TB treatment), and treatment experience (i.e. lack of TB education provided by TB nurse and the use of loose vs. fixed-dose combinations) were associated with non-adherence during TB treatment in the adjusted model, as were being aged under 35 years and having a history of TB in the family.

CONCLUSION

Our results suggest the need to improve TB treatment delivery especially to those who have difficult access to healthcare, and to routinely provide education to increase patients' knowledge about TB and TB treatment. In addition, more attention to younger patients and those with a history of TB in their family is also needed.

Substance use in kidney transplant candidates and its impact on access to kidney transplantation

BACKGROUND

Due to the increasing public acceptance of substance use, it is important to understand the association between substance use and access to kidney transplant and its outcomes. Here, we assess the sociodemographic predictors of substance use and the association between substance use and KT access.

METHODS

Predictors of substance use were examined using a multivariable-adjusted multinomial logistic regression. The association between current substance use (tobacco and drug) and time from referral to listing or receipt of a KT was examined using Cox proportional hazards models.

RESULTS

Of 2346 patients, the prevalence of current substance use was 17%. Predictors of current tobacco use were younger age, male sex, Caucasian ethnicity, being unemployed, and unmarried. Predictors of current drug use were younger age, male sex, Caucasian ethnicity, a history of non-adherence, and a history of mental health disorder. Patients with tobacco use had a decreased likelihood of being cleared for KT (hazard ratio [HR]:0.83[0.70, 0.99]) and receiving a KT (HR:0.80 [0.66, 0.96]). No association was seen in this sample for patients with drug use (HR:0.88 [0.69, 1.11] for being cleared for KT and 0.88 [0.69, 1.14] for KT, respectively).

CONCLUSIONS

Tobacco use was associated with a decreased likelihood of access to KT whereas there was no statistically significant difference in access to KT between patients with or without drug use.

Mobile Health for Tuberculosis Management in South India: Is Video-Based Directly Observed Treatment an Acceptable Alternative?

Background

With the availability of low-cost mobile devices and the ease of internet access, mobile health (mHealth) is digitally revolutionizing the health sector even in resource-constrained settings. It is however necessary to assess end-user perceptions before deploying potential interventions.

Objective

This study aimed to assess the mobile phone usage patterns and the acceptability of mobile phone support during care and treatment in patients with tuberculosis (TB) in South India.

Methods

This exploratory study was conducted at an urban private tertiary care teaching hospital and nearby public primary-level health care facilities in Bangalore, South India. We recruited 185 patients with TB through consecutive sampling. Subsequent to written informed consent, participants responded to an interviewer-administered pretested questionnaire. The questionnaire included questions on demographics, phone usage patterns, and the benefits of using of mobile phone technology to improve health outcomes and treatment adherence. Frequency, mean, median, and SD or interquartile range were used to describe the data. Bivariate associations were assessed between demographics, clinical details, phone usage, and mHealth communication preferences using the chi-square test and odds ratios. Associations with a P value ≤.20 were included in a logistic regression model. A P value of <.05 was considered significant.

Results

Of the 185 participants, 151 (81.6%) used a mobile phone, and half of them owned a smartphone. The primary use of the mobile phone was to communicate over voice calls (147/151, 97.4%). The short message service (SMS) text messaging feature was used by only 66/151 (43.7%) mobile phone users. A total of 87 of the 151 mobile phone users (57.6%) knew how to use the camera. Only 41/151 (27.2%) mobile phone users had used their mobile phones to communicate with their health care providers. Although receiving medication reminders via mobile phones was acceptable to all participants, 2 participants considered repeated reminders as an intrusion of their privacy. A majority of the participants (137/185, 74.1%) preferred health communications via voice calls. Of the total participants, 123/185 (66.5%) requested reminders to be sent only at specific times during the day, 22/185 (11.9%) suggested reminders should synchronize with their prescribed medication schedule, whereas 40/185 (21.6%) did not have any time preferences. English literacy was associated with a preference for SMS in comparison with voice calls. Most participants (142/185, 76.8%) preferred video-based directly observed treatment when compared with in-person directly observed treatment.

Conclusions

Although mobile phones for supporting health and treatment adherence were acceptable to patients with TB, mHealth interventions should consider language, mode of communication, and preferred timing for communication to improve uptake.

Neurocognitive Impairment Risk Among Individuals With Multiple Drug-Resistant Tuberculosis and Human Immunodeficiency Virus Coinfection: Implications for Systematic Linkage to and Retention of Care in Tuberculosis/Human Immunodeficiency Virus Treatment

Although neurocognitive impairment (NCI) is a well-recognized challenge in human immunodeficiency virus (HIV), there is little evidence regarding it among individuals with multiple drug-resistant tuberculosis (MDR-TB) within HIV endemic sub-Saharan Africa. The extent of NCI risk, particularly HIV-associated neurocognitive disorders (HAND) risk, was investigated in 200 microbiologically confirmed inpatients with MDR-TB at a TB-specialist hospital in KwaZulu-Natal Province, South Africa. Within this population, the prevalence of HIV coinfection, major depressive episode, and substance use disorder was 89.50%, 10.50%, and 7.00%, respectively. After excluding individuals with major depressive episode/substance use disorder and monoinfection (i.e., MDR-TB without HIV), the prevalence of HAND risk was 43.5%. Older and low-income individuals had significantly greater odds of HAND risk, whereas those with family members/relatives who work(ed) in the health services had lower odds. The role of timely linkage to and retention of care in TB/HIV treatment to offset cognitive decline in MDR-TB/HIV coinfected individuals needs to be investigated further.

Unsuccessful treatment in pulmonary tuberculosis: factors and a consequent predictive model

Background

Cure is particularly valuable in pulmonary cases (PTB), as unsuccessful treatment fuels incidence and resistance to antibiotics. This study aims to identify individual factors of PTB unsuccessful treatment in Portugal and to develop a consequent predictive model.

Methods

Using the Portuguese TB surveillance database (SVIG-TB), PTB cases older than 15 years notified from 2000 to 2012 in Continental Portugal were analyzed. Unsuccessful treatment included the WHO categories (failure, default, death and transferred out). Based on a literature review, predictors involved sociodemographic, behavioral, disease-related and treatment-related factors. Binary logistic regression was used to estimate unsuccessful treatment factors and to develop the predictive risk model.

Results

The unsuccessful outcome rate in PTB patients was of 11.9%. The predictive model included the following factors: TB/HIV co-infection (OR 4.93), age over 64 years (OR 4.37), IV drugs abuse (OR 2.29), other diseases (excluding HIV and Diabetes, OR 2.09) and retreatment (OR 1.44), displaying a rather good validity.

Conclusion

The overall treatment unsuccessful treatment rate in PTB patients complies with the 85% WHO success threshold. The predictive model of unsuccessful treatment proved well. Nomogram representation allows an early, intuitive identification of PTB patients at increased risk. The model is liable to widespread use as a prognostic tool.

Non-adherence to anti-tuberculosis treatment, reasons and associated factors among TB patients attending at Gondar town health centers, Northwest Ethiopia

Objective

The aim of this study was to assess the prevalence of non-adherence to anti-tuberculosis treatment, reasons and associated factors among TB patients attending at Gondar town health centers.

Result

A total of 314 participants were included with the response rate of 97.5%. The mean age of participants was 35.94 (SD ± 13.83) years. The overall rate of non-adherence to anti-TB treatment was 21.2% (95% CI 17.2, 26.1). Continuation phase of treatment (AOR = 2.27, 95% CI (1.54, 5.94)), presence of more than one co-morbidity (AOR = 6.22; 95% CI (2.21, 17.48)), poor knowledge about TB and anti-TB therapy (AOR = 4.11; 95% CI 1.57, 10.75), poor patient-provider relationship (AOR = 4.60, 95% CI 1.63, 12.97), and alcohol intake (AOR = 5.03; 95% CI 1.54, 16.40) were significantly associated with non-adherence. Forgetting 40 (23.1%), Being busy with other work 35 (20.2%), and being out of home/town 24 (13.9%) were the major reasons of participants for interruption of taking anti-TB medications.

Recurrent tuberculosis among HIV-coinfected patients: a case series from KwaZulu-Natal

Background

Recurrent tuberculosis (TB) following TB treatment completion in HIV-infected individuals remains a major public health burden. We assessed the role of various risk factors in mediating the development of recurrent TB and subsequent resistance to antiretroviral therapy and anti-TB drugs.

Patients and methods

We analyzed secondary demographic, clinical, and laboratory data from medical records of five HIV-infected TB patients enrolled between 2009 and 2014 in a prospective observational study investigating TB recurrence. Paired clinical isolates of Myco-bacterium tuberculosis were typed by IS6110 restriction fragment length polymorphism analysis to determine the mechanism of TB recurrence. Plasma samples were genotyped to determine acquisition of HIV drug resistance mutations on antiretroviral treatment (ART).

Results

All five patients were HIV-coinfected, with a previous history of TB infection and prior exposure to anti-TB treatment, and residual lung damage, and demonstrated poor treatment adherence – significant risk factors linked to the development of recurrent TB disease. Furthermore, three of the five patients had multiple episodes of drug-susceptible TB infection with subsequent drug-resistant TB infection. Genotyping of the initial and recurrent M. tuberculosis isolates demonstrated three cases of recurrent TB because of relapse and two because of reinfection. All five patients had no mutations at ART initiation; however, by the end of the study follow-up, all patients developed dual class resistance.

Conclusion

This series demonstrates the complexity of recurrent TB in HIV coinfection. We highlight the challenges of managing coinfected patients and the increased propensity for the development of drug resistance. We report on the role of various risk factors mediating the development of resistance and subsequent clinical impact. This report underscores the need for structural clinical and adherence interventions for the management of complex treatment and dosing.

Depression comorbid with tuberculosis and its impact on health status: cross-sectional analysis of community-based data from 48 low- and middle-income countries

BACKGROUND

Depression in tuberculosis increases the risk for adverse health outcomes. However, little is known about comorbid depression and tuberculosis in the general population. Thus, we assessed the association between depression and tuberculosis, and the decrements in health status associated with this comorbidity in 48 low- and middle-income countries.

METHODS

Cross-sectional, community-based data from the World Health Survey on 242,952 individuals aged ≥ 18 years were analyzed. Based on the World Mental Health Survey version of the Composite International Diagnostic Interview, past 12-month depression was categorized into depressive episode, brief depressive episode, subsyndromal depression, and no depression. Health status across six domains (cognition, interpersonal activities, sleep/energy, self-care, mobility, pain/discomfort) was assessed. Multivariable logistic and linear regression analyses were performed to assess the associations.

RESULTS

The prevalence of depressive episode among those with and without tuberculosis was 23.7% and 6.8%, respectively (P < 0.001). Tuberculosis was associated with a 1.98 (95% CI 1.47-2.67), 1.75 (95% CI 1.26-2.42), and 3.68 (95% CI 3.01-4.50) times higher odds for subsyndromal depression, brief depressive episode, and depressive episode, respectively. Depressive episode co-occurring with tuberculosis was associated with significantly worse health status across all six domains compared to tuberculosis alone. Interaction analysis showed that depression significantly amplifies the association between TB and difficulties in self-care but not in other health domains.

CONCLUSIONS

Depression is highly prevalent in adults with tuberculosis, and is associated with worse health status compared to tuberculosis without depression. Public health efforts directed to the recognition and management of depression in people with tuberculosis may lead to better outcomes.

Tuberculosis Treatment Adherence of Patients in Kosovo

Setting

The poor patient adherence in tuberculosis (TB) treatment is considered to be one of the most serious challenges which reflect the decrease of treatment success and emerging of the Multidrug Resistance-TB (MDR-TB). To our knowledge, the data about patients' adherence to anti-TB treatment in our country are missing.

Objective

This study was aimed to investigate the anti-TB treatment adherence rate and to identify factors related to eventual nonadherence among Kosovo TB patients.

Design

This study was conducted during 12 months, and the survey was a descriptive study using the standardized questionnaires with total 324 patients.

Results

The overall nonadherence for TB patient cohort was 14.5%, 95% CI (0.109–0.188). Age and place of residence are shown to have an effect on treatment adherence. Moreover, the knowledge of the treatment prognosis, daily dosage, side effects, and length of treatment also play a role. This was also reflected in knowledge regarding compliance with regular administration of TB drugs, satisfaction with the treatment, interruption of TB therapy, and the professional monitoring in the administration of TB drugs.

Conclusion

The level of nonadherence TB treatment in Kosovar patients is not satisfying, and more health care worker's commitments need to be addressed for improvement.

Adherence to Childhood Tuberculosis Treatment in Mozambique

BACKGROUND

There is limited literature regarding adherence rates for the treatment of tuberculosis (TB) in children. We aimed to describe TB treatment outcomes and adherence as well as to evaluate associated factors to poor adherence in Mozambican children.

METHODS

This is a sub-study of a community TB incidence study among children <3 years of age. Incomplete adherence included the sum of lost-to-follow-up cases plus those with a delay of > 3 weeks to treatment completion.

RESULTS

Fifty TB treatments were assessed. Forty-four (88.0%) patients completed treatment, two (4.0%) died during treatment and four (8.0%) were lost to follow-up. Incomplete adherence was observed in 31.3% (15 of 48) of cases and was associated with malnutrition or history of a migrant mother.

CONCLUSION

Although treatment outcome is overall good, there is still a significant proportion of incomplete adherence. Further larger paediatric TB cohorts and qualitative approaches are needed to assess and confirm potential factors for non-adherence.

The prevalence and factors associated for anti-tuberculosis treatment non-adherence among pulmonary tuberculosis patients in public health care facilities in South Ethiopia: a cross-sectional study

BACKGROUND

Evidence exists pointing out how non-adherence to treatment remains a major hurdle to efficient tuberculosis control in developing countries. Many tuberculosis (Tb) patients do not complete their six-month course of anti-tuberculosis medications and are not aware of the importance of sputum re-examinations, thereby putting themselves at risk of developing multidrug-resistant and extensively drug-resistant forms of tuberculosis and relapse. However, there is a dearth of publications about non-adherence towards anti-Tb medication in these settings. We assessed the prevalence of and associated factors for anti-Tb treatment non-adherence in public health care facilities of South Ethiopia.

METHODS

This was a cross-sectional survey using both quantitative and qualitative methods. The quantitative study was conducted among 261 Tb patients from 17 health centers and one general hospital. The qualitative aspect included an in-depth interview of 14 key informants. For quantitative data, the analysis of descriptive statistics, bivariate and multiple logistic regression was carried out, while thematic framework analysis was applied for the qualitative data.

RESULTS

The prevalence of non-adherence towards anti-Tb treatment was 24.5%. Multiple logistic regression analysis demonstrated that poor knowledge towards tuberculosis and its treatment (AOR = 4.6, 95%CI: 1.4-15.6), cost of medication other than Tb (AOR = 4.7, 95%CI: 1.7-13.4), having of health information at every visit (AOR = 3, 95% CI: 1.1-8.4) and distance of DOTS center from individual home (AOR = 5.7, 95%CI: 1.9-16.8) showed statistically significant association with non-adherence towards anti- tuberculosis treatment. Qualitative study also revealed that distance, lack of awareness about importance of treatment completion and cost of transportation were the major barriers for adherence.

CONCLUSIONS

A quarter of Tb patients interrupted their treatment due to knowledge, availability and accessibility of DOTS service. We recommend creating awareness about anti-Tb treatment, and decentralization of drug pick-ups to the lowest level of health institutions.

Treatment compliance and noncompliance in psychoses

BACKGROUND

Compliance or noncompliance with treatment significantly influences course and outcome of psychiatric disorders. While noncompliance has been extensively researched, compliance has received less attention. The current study was conducted to elicit reasons for compliance and noncompliance in patients having psychoses attending psychiatric clinics.

MATERIALS AND METHODS

A total of 196 compliant and 150 noncompliant patients were interviewed using self-designed tools to elicit sociodemographic data, details of illness, and treatment. Factors contributing to compliance and noncompliance were grouped under illness-related, clinician-related, medication-related, family-related, and economic-related domains and compared.

RESULTS

Compliance was significantly more in females and middle- and high-socioeconomic status patients. They had less substance use, high physical comorbidity, high attendance in the outpatient department, and better remission. Clinician-related, family-related, and medication-related domains were contributing more to compliance whereas illness-related and economic-related domains seemed to have more bearing on noncompliance.

CONCLUSIONS

Compliance and noncompliance are determined multidimensionally. Domains related to clinician, family, and medications have to be reinforced to enhance compliance. Illness-related and economic domains have to be resolved to reduce noncompliance.
