One dollar incentive improves tuberculosis treatment outcomes in programmatic settings in rural Uganda

AbstractThe study aim was to determine the association of a one United States dollar (USD) dollar incentive and tuberculosis (TB) treatment outcomes among people with TB receiving treatment at a rural hospital in Uganda under programmatic settings. We conducted a quasi-experiment in which people with TB were randomised (1:1 ratio) to receive either a one USD incentive at months 0, 2, 5 and 6 (Dollar arm) or routine care (Routine arm). A second control group (Retrospective controls) consisted of participants who had a treatment outcome in the preceding 6 months. Treatment outcomes were compared between the intervention and control groups using Pearson’s chi-square and Fisher’s exact tests. The association between the incentive and treatment outcomes was determined using Poisson regression analysis with robust variances. Between November 2018 and October 2019, we enrolled 180 participants (60 in the Dollar arm and 120 in the Control group). TB cure (33.3% vs. 20.8%, p = 0.068) and treatment success (70.0% vs. 59.2% p = 0.156) were higher in the Dollar arm than the Control group, while loss-to-follow-up was lower in the Dollar arm (10.0% vs. 20.8% p = 0.070). Participants in the Dollar arm were more likely to be cured (adjusted incidence rate ratio (aIRR): 1.59, 95% CI 1.04–2.44, p = 0.032) and less likely to be lost to follow-up (aIRR: 0.44, 95% CI 0.20–0.96, p = 0.040). A one-dollar incentive was associated with higher TB cure and lower loss-to-follow-up among people with TB in rural Uganda.

Uzbekistan has a high burden of drug-resistant tuberculosis (TB). Although conventional treatment for multidrug-resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB) has been available since 2013, there has been no systematic documentation about its use and effectiveness. We therefore documented at national level the trends, characteristics, and outcomes of patients with drug-resistant TB enrolled for treatment from 2013–2018 and assessed risk factors for unfavorable treatment outcomes (death, failure, loss to follow-up, treatment continuation, change to XDR-TB regimen) in patients treated in Tashkent city from 2016–2017. This was a cohort study using secondary aggregate and individual patient data. Between 2013 and 2018, MDR-TB numbers were stable between 2347 and 2653 per annum, while XDR-TB numbers increased from 33 to 433 per annum. At national level, treatment success (cured and treatment completed) for MDR-TB decreased annually from 63% to 57%, while treatment success for XDR-TB increased annually from 24% to 57%. On multivariable analysis, risk factors for unfavorable outcomes, death, and loss to follow-up in drug-resistant TB patients treated in Tashkent city included XDR-TB, male sex, increasing age, previous TB treatment, alcohol abuse, and associated comorbidities (cardiovascular and liver disease, diabetes, and HIV/AIDS). Reasons for these findings and programmatic implications are discussed.

Abstract Background: Tuberculosis (TB) remains a major cause of avoidable deaths. Economic migrants represent a vulnerable population due to their exposure to medical and social risk factors. These factors expose them to higher risks for TB incidence and poor treatment outcomes. Methods: This cross-sectional study evaluated WHO-defined TB treatment outcomes among economic migrants in an urban district of Ho Chi Minh City, Viet Nam. We measured the association of a patient’s government-defined residency status with treatment success and loss to follow-up categories at baseline and performed a comparative interrupted time series (ITS) analysis to assess the impact of community-based adherence support on treatment outcomes. Key measures of interest of the ITS were the differences in step change (β6) and post-intervention trend (β7). Results: Short-term, inter-province migrants experienced lower treatment success (aRR=0.95 [95% CI: 0.92-0.99], p=0.010) and higher loss to follow-up (aOR=1.98 [95% CI: 1.44-2.72], p<0.001) than permanent residents. Intra-province migrants were similarly more likely to be lost to follow-up (aOR=1.86 [95% CI: 1.03-3.36], p=0.041). There was evidence that patients >55 years of age (aRR=0.93 [95% CI: 0.89-0.96], p<0.001), relapse patients (aRR=0.89 [95% CI: 0.84-0.94], p<0.001), and retreatment patients (aRR=0.62 [95% CI: 0.52-0.75], p<0.001) had lower treatment success rates. TB/HIV co-infection was also associated with lower treatment success (aRR=0.77 [95% CI: 0.73-0.82], p<0.001) and higher loss to follow-up (aOR=2.18 [95% CI: 1.55-3.06], p<0.001). The provision of treatment adherence support increased treatment success (IRR(β6)=1.07 [95% CI: 1.00, 1.15], p=0.041) and reduced loss to follow-up (IRR(β6)=0.17 [95% CI: 0.04, 0.69], p=0.013) in the intervention districts. Loss to follow-up continued to decline throughout the post-implementation period (IRR(β7)=0.90 [95% CI: 0.83, 0.98], p=0.019). Conclusions: Economic migrants, particularly those crossing provincial borders, have higher risk of poor treatment outcomes and should be prioritized for tailored adherence support. In light of accelerating urbanization in many regions of Asia, implementation trials are needed to inform evidence-based design of strategies for this vulnerable population.

Retrievable IVC filters (R-IVCF) are associated with multiple complications, including filter migration and deep venous thrombosis. Unfortunately, most series of R-IVCF show low retrieval rates, often due to loss to follow-up. This study demonstrates that actively tracking R-IVCF improves retrieval. Trauma patients at one institution with R-IVCF placed between January 2007 and January 2011 were tracked in a registry with a goal of retrieval. These were compared to a control group who had R-IVCF placed previously (December 2005 to December 2006). Outcome measures include filter retrieval, retrieval attempts, loss to follow-up, and time to filter retrieval. We compared 93 tracked patients with R-IVCF with 20 controls. The baseline characteristics of the groups were similar. Tracked patients had significantly higher rates of filter retrieval (60% vs 30%, P = 0.02) and filter retrieval attempts (70% vs 30%, P = 0.002) and were significantly less likely to be lost to follow-up (5% vs 65%, P < 0.0001). Time to retrieval attempt was 84 days in the registry versus 210 days in the control group, which trended towards significance ( P = 0.23). Tracking patients with R-IVCF leads to improved retrieval rates, more retrieval attempts, and decreased loss to follow up. Institutions should consider tracking R-IVCF to maximize retrieval rates.

Non-adherence to tuberculosis (TB) treatment is a barrier to effective TB control. We investigated the effectiveness of a Medication Event Monitoring System (MEMS) as a tailored adherence-promoting intervention in Morocco. We compared patients who received a MEMS (n = 206) with patients who received standard TB care (n = 141) among new active TB patients with sputum smear-positive. The mean total medication days were 141.87 ± 29.5 in the control group and 140.85 ± 17.9 in the MEMS group (p = 0.7147), and the mean age and sex were not different between the two groups (p > 0.05). The treatment success rate was significantly higher in the MEMS group than in the control group (odds ratio (OR): 4.33, 95% confidence interval (CI): 2.13–8.81, p < 0.001), and the lost to follow-up rate was significantly lower in the MEMS group than in the control group (OR: 0.03, 95% CI: 0.05–0.24, p < 0.001) after adjusting for sex, age, and health centers. The mean drug adherence rate in the first month was significantly higher in the MEMS group than in the control group (p = 0.023). MEMS increased TB treatment success rate and decreased the lost to follow-up rate overall for infectious TB patients in a Moroccan rural area.

Setting. Zimbabwe is a high tuberculosis (TB) burden country, with an estimated prevalence of 344/100,000 population. Though prisons are known high-prevalence sites for TB, the paucity of data affects the quantification of the disease and treatment outcomes in these settings. We measured the prevalence of TB disease and treatment outcomes among inmates at two major prisons in Harare, Zimbabwe. Design. A cohort study using programmatic data was undertaken to assess TB diagnostic cascade in one of the study prisons for 2018. Treatment outcomes among male inmates with TB were assessed over a period of four years, in two study prisons. Results. A total of 405 (11%) inmates with presumptive TB were identified, and 370 (91%) of these were evaluated for TB, mostly using rapid molecular testing of sputum specimens. Twenty-five inmates were diagnosed with TB resulting in a prevalence of 649/100,000 population. Of these, 16 (64%) were started on treatment. Nine (36%) were lost to follow-up before treatment initiation. From 2015 to 2018, 280 adult male inmates with TB were started on treatment. Of these, 212 (76%) had pulmonary disease that was bacteriologically confirmed. Almost all (276/280, 99%) had known HIV status, 65% were HIV-infected, and 80% of these were on antiretroviral treatment. The TB treatment success rate (cured or treatment completed) was recorded for 209 (75%) inmates, whilst 14 (5%) died and 11 (4%) were lost to follow-up. The frequency of unfavourable treatment outcomes (death, lost to follow-up, and not evaluated) was higher (54%) among inmates≥60 years than those in the age group of 45-59 years (17%). Conclusion. The findings revealed a threefold burden of TB in prisons, compared with what is reported by national survey. To decrease transmission of TB bacilli, it is essential to promote efforts that address missed opportunities in the TB diagnostic cascade, prompt treatment initiation, and ensure that tracking and documentation of treatment outcomes for all inmates are intensified.

SETTING: An urban TB diagnostic centre in Lusaka, Zambia.OBJECTIVE: To re-evaluate treatment outcomes of all bacteriologically confirmed TB patients registered in 2018.DESIGN: This was a retrospective cohort study on TB patients. Treatment outcomes of patients who were transferred out were retrieved.RESULTS: A total of 182 patients were registered, 26 of whom had missing documents; these were excluded from the study. Of the remaining 156 patients who were reviewed, 86 (55.1%) were correctly evaluated by the centre, 35 (22.4%) were incorrectly evaluated and 35 (22.4%) were ‘transferred out’ (not evaluated). As a result of this review, the number of evaluated patients increased from 86 (55.1%) to 150 (96.2%). The cure and treatment success rates rose from 43.6% and 44.2%, respectively, to 57.7% and 73.1%, respectively. Of note, 14 of the 35 patients who were initially declared ‘transferred out’ did not actually reach their treatment facilities and ended up being lost to follow-up.CONCLUSION: This study shows that it is possible to evaluate almost all TB patients. Re-evaluation of treatment outcomes of TB patients revealed the problems in the TB services that need to be improved in the future.

Setting: Targeted active screening for tuberculosis (Tas4TB) using mobile trucks in the community was implemented in 15 high TB burden districts in Zimbabwe. At-risk populations were screened for TB based on symptoms and chest radiography (CXR) results. Those with any positive symptom and/or an abnormal CXR had sputum collected for investigation and diagnosis and were linked to care and treatment if found to have TB.Objective: To determine 1) the proportion and characteristics of those screened and diagnosed with TB; 2) the relationship between TB symptoms, CXR and diagnostic yields; and 3) the relationship between initiation of anti-TB treatment and treatment outcomes.Design: Cohort study using routinely collected dataResults: A total of 39 065 persons were screened, of whom 663 (1.7%) were diagnosed with TB; 126/663 (19.0%) were bacteriologically confirmed. The highest TB diagnostic yields were in symptomatic persons with CXRs suggestive of TB (19.4%), asymptomatic persons with CXRs suggestive of TB (8.4%) and persons at high-risk of TB (3.2%). For all diagnosed TB patients, pre-treatment loss to follow-up was 18.9% and treatment success was 59.9%.Conclusion: Tas4TB resulted in high diagnostic yields; however, linkage of diagnosis to care was poor. Reasons for loss to follow-up need to be better understood and rectified.

Introduction: Multidrug-resistant tuberculosis treatment is effective in 50% of patients due to several factors including antibiotic susceptibility of the microorganism, adverse treatment reactions, social factors, and associated comorbidities.Objectives: In this study, we describe the demographics, clinical characteristics, and factors associated with treatment outcomes in multidrug-resistant tuberculosis (MDR-TB) patients in Medellín, Colombia.Materials and methods: We conducted a retrospective analysis using data from patients diagnosed with MDR-TB attending Hospital La María in Medellín, Colombia, for treatment between 2010 and 2015. Patients were categorized as having successful (cured) or poor (failure, lost to follow-up, and death) treatment outcomes. Associations between demographic, clinical factors, laboratory results, treatment outcomes, and follow-up information were evaluated by univariate, multivariate, and multiple correspondence analyses.Results: Of the 128 patients with MDR-TB, 77 (60%) had successful outcomes. Of those with poor outcomes, 26 were lost to follow-up, 15 died, and 10 were treatment failures. Irregular treatment, the presence of comorbidities, and positive cultures after more than two months of treatment were associated with poor outcomes compared to successful ones (p<0.05 for all). The multiple correspondence analyses grouped patients who were lost to follow-up, had HIV, and drug addiction, as well as patients with treatment failure, irregular treatment, and chronic obstructive pulmonary disease.Conclusion: The recognition of factors affecting treatment is essential and was associated with treatment outcomes in this series of patients. Early identification of these factors should increase the rates of treatment success and contribute to MDR-TB control.

Background: Ukraine has high rates of poor treatment outcomes among drug sensitive tuberculosis (DSTB) patients, while global treatment success rates for DSTB remain high. We evaluated baseline patient factors as predictors of poor DSTB treatment outcomes. Methods: We conducted a retrospective analysis of new drug sensitive pulmonary TB patients treated in Kyiv Oblast, Ukraine between November 2012 and October 2014. We defined good treatment outcomes as cure or completion and poor outcomes as death, default (lost to follow up) or treatment failure. We performed logistic regression analyses, using routine program data, to identify baseline patient factors associated with poor outcomes. Results: Among 302 patients, 193 (63.9%) experienced good treatment outcomes while 39 (12.9%) failed treatment, 34 (11.3%) died, and 30 (9.9%) were lost to follow up. In the multivariate analysis, HIV positive patients on anti-retroviral therapy (ART) [OR 3.50; 95% CI 1.46 – 8.42; p 0.005] or without ART (OR 4.12; 95% CI 1.36 – 12.43; p 0.01) were at increased risk of poor outcomes. Smear positivity (OR 1.75; 95% CI 1.03 - 2.97; p 0.04) was also associated with poor treatment outcomes. Conclusions: High rates of poor outcomes among patients with newly diagnosed drug sensitive TB in Kyiv Oblast, Ukraine highlight the urgent need for programmatic interventions, especially aimed at patients with the highest risk of poor outcomes.

Abstract Background: Tuberculosis (TB) remains a major cause of avoidable deaths. Economic migrants represent an underserved population due to their exposure to medical and social risk factors, which can affect their health. Methods: This cross-sectional study evaluated WHO-defined TB treatment outcomes among economic migrants in an urban district of Ho Chi Minh City, Viet Nam. We measured the association of a patient’s government-defined residency status with treatment success and loss to follow-up categories at baseline and performed a comparative interrupted time series analysis to assess the impact of community-based adherence support on treatment outcomes. Results: Short-term, inter-province migrants experienced lower treatment success (aRR=0.95 [0.92-0.99], p=0.010) and higher loss to follow-up (aOR=1.98 [1.44-2.72], p<0.001) than permanent residents. Intra-province migrants were similarly more likely to be lost to follow-up (aOR=1.86 [1.03-3.36], p=0.041). There was evidence that patients >55 years of age (aRR=0.93 [0.89-0.96], p<0.001), relapse patients (aRR=0.89 [0.84-0.94], p<0.001), and retreatment patients (aRR=0.62 [0.52-0.75], p<0.001) had lower treatment success rates. TB/HIV co-infection was also associated with lower treatment success (aRR=0.77 [0.73-0.82], p<0.001) and higher loss to follow-up (aOR=2.18 [1.55-3.06], p<0.001). The provision of treatment adherence support increased treatment success (IRR(β6)=1.07 [1.00, 1.15], p=0.041) and reduced loss to follow-up (IRR(β6)=0.17 [0.04, 0.69], p=0.013) in the intervention districts. Loss to follow-up continued to decline throughout the post-implementation period (IRR(β7)=0.90 [0.83, 0.98], p=0.019). Conclusions: Economic migrants, particularly those crossing provincial borders, have higher risk of poor treatment outcomes and should be prioritized for tailored adherence support. In light of accelerating urbanization in many regions of Asia, implementation trials are needed to inform evidence-based design of strategies for this vulnerable population.
