Estimating the budget impact of a Tuberculosis strategic purchasing pilot study in Medan, Indonesia (2018–2019)

BackgroundIndonesia has the world’s second-highest tuberculosis (TB) burden, with 969,000 annual TB infections. In 2017, Indonesia faced significant challenges in TB care, with 18% of cases missed, 29% of diagnosed cases unreported, and 55.4% of positive results not notified. The government is exploring a new approach called “strategic purchasing” to improve TB detection and treatment rates and offer cost-effective service delivery.ObjectivesWe aimed to analyze the financial impact of implementing a TB purchasing pilot in the city of Medan and assess the project’s affordability and value for money.MethodsWe developed a budget impact model to estimate the cost-effectiveness of using strategic purchasing to improve TB reporting and treatment success rates. We used using data from Medan’s budget impact model and the Ministry of Health’s guidelines to predict the total cost and the cost per patient.ResultsThe model showed that strategic purchasing would improve TB reporting by 63% and successful treatments by 64%. While this would lead to a rise in total spending on TB care by 60%, the cost per patient would decrease by 3%. This is because more care would be provided in primary healthcare settings, which are more cost-effective than hospitals.ConclusionsWhile strategic purchasing may increase overall spending, it could improve TB care in Indonesia by identifying more cases, treating them more effectively, and reducing the cost per patient. This could potentially lead to long-term cost savings and improved health outcomes.

Pharmacists' Role in Global TB Elimination: Practices, Pitfalls, and Potential.

Tuberculosis (TB) is the top infectious killer in the world despite efforts to eliminate it. Pharmaceutical care roles are pillars of pharmacy practice, and pharmacists are well equipped to serve a unique role in the pathway to provide education about TB. Previous systematic reviews emphasize pharmacists' role in treating TB; however, pharmacists can and do play much broader roles in overall TB elimination efforts. Five researchers searched five electronic databases (PubMed, PsychInfo, CINAHL, Academic Search Premier, and Embase). Search terms included pharmacy, pharmacist, tuberculosis, antitubercular agents, supply, distribution, and drug therapy. Inclusion criteria were studies published from 2010 through March 2023, in English or Spanish, addressed a specific TB-related role for pharmacists/pharmacies, and were peer-reviewed. Exclusion criteria included pharmacology, pharmacokinetics, clinical trials on drug efficacy, and editorials. Two researchers conducted each level of review; for discordance, a third researcher reviewed, and a decision was reached by consensus. Roles were extracted and cross-referenced with traditional pharmaceutical care steps. Of the initial 682 hits, 133 were duplicates. After further review, we excluded 514 records, leaving 37 articles for full extraction. We found nine roles for pharmacists in TB prevention and classified them as implemented, not implemented, or recommended. These roles were: (1) TB symptom screening; (2) Referring to TB care systems; (3) TB testing; (4) Dispensing TB medication correctly and/or directly observed therapy; (5) Counseling; (6) Looking to reduce socioeconomic barriers; (7) Procurement of TB medications; (8) Quality assurance of TB medications; (9) Maintaining and using pharmacy data systems. Pharmacists are well situated to play a vital role in the global fight against TB. Findings suggested pharmacists in many settings have already expanded their roles related to TB elimination beyond traditional pharmaceutical care. Still others need to increase the understanding of TB procurement and treatment, their power to improve TB care, and their contributions to data systems that serve population health. Pharmacy curricula should increase TB-related training to better equip future pharmacists to contribute to TB elimination.

Finding the missing many: improving Tuberculosis care in Kajiado county through active case finding and community approaches

BackgroundTuberculosis related deaths remain a priority globally. Despite advancements in TB care, access to quality care remains inequitable to the disadvantage of those in rural and urban informal settlements. The Awareness, Traditions, and Innovation in combating Tuberculosis (ATI TB) project incorporated active case finding (ACF), use of GeneXpert technology and decentralized services to improve TB care in Kajiado County. This study sought to establish the impact of the project as well as implementation lessons learnt during its tenure in Kajiado County, Kenya.MethodsThis evaluation adopted a mixed-methods approach with retrospective cohort analysis for the quantitative data and qualitative data sought through key informant interviews with 28 purposively sampled respondents. The qualitative data was analyzed thematically using Taguette while quantitative data was analyzed using R Software yielding descriptive statistics and measures of association.ResultsWhile the males were a minority among the presumptive cases (623; 46%), they were the majority (59.3%) among the confirmed TB cases. 70% of the confirmed cases were aged between 15 and 44 years; with those aged between 25- and 34-years being majority (30% of the cases). Majority of the confirmed cases within the project were from rural Kajiado West (79; 66.9%). Though 61% of the presumptive cases were through ACF, only 7% of these tested positive. Conversely, 13% of the self-referrals tested positive. 53% (66) of the positive cases with valid data were self-referrals while ACF accounted for 47% (58) of the positives.ConclusionContinued capacity development among health workers, sustained and targeted sensitization and screening among vulnerable groups, strategic collaborations, alongside increased budgetary prioritization of health and TB care by government and partners, and government investments in Social Determinants of Health can ensure gains in TB care are sustained.

Mapping the effectiveness of the community tuberculosis care programs: a systematic review

BackgroundTuberculosis is a significant global public health threat, especially in countries with limited resources. To improve tuberculosis care, the World Health Organization emphasizes the importance of considering a TB patient’s journey across a variety of connected settings and facilities. A systematic review was conducted to map previously conducted studies to identify existing community TB implementation models, their effectiveness on cost, and treatment outcomes.MethodsSystematic search through various electronic databases MEDLINE, EBSCO (PsycINFO and CINAHL), Cochrane Library, EMBASE, WHO Regional Databases, gray literature, and hand-searched bibliographies was performed. Articles published in English between the years 2000 and 2022 with a substantial focus on community TB implementation models were considered for inclusion. Studies were excluded if the intervention was purely facility-based and those focusing exclusively on qualitative assessments. Two reviewers used standardized methods to screen titles, abstracts, and data charting. Included studies were assessed for quality using ROBINS-I and ROB 2. Analysis of study results uses a PRISMA flow diagram and quantitative approach.ResultsA total of 6982 articles were identified with 36 meeting the eligibility criteria for analysis. Electronic medication monitors showed an increased probability of treatment success rate (RR 1.0–4.33 and the 95% CI 0.98–95.4) in four cohort studies in low- and middle-income countries with the incremental cost-effectiveness of $434. Four cohort studies evaluating community health worker direct observation therapy in low- and middle-income countries showed a treatment success risk ratio of up to 3.09 with a 95% CI of 0.06–7.88. (32,41,43,48) and incremental cost-effectiveness up to USS$410. Moreover, four comparative studies in low- and middle-income countries showed family directly observed treatment success risk ratio up to 9.07, 95% CI of 0.92–89.9. Furthermore, four short message service trials revealed a treatment success risk ratio ranging from 1.0 to 1.45 (95% CI fell within these values) with a cost-effectiveness of up to 350I$ compared to standard of care.ConclusionsThis review illustrates that community-based TB interventions such as electronic medication monitors, community health worker direct observation therapy, family directly observed treatment, and short message service can substantially bolster efficiency and convenience for patients and providers while reducing health system costs and improving clinical outcomes.

Geographic mobility and treatment outcomes among people in care for tuberculosis in the Lake Victoria region of East Africa: A multi-site prospective cohort study.

Geographic mobility may disrupt continuity of care and contribute to poor clinical outcomes among people receiving treatment for tuberculosis (TB). This may occur especially where health services are not well coordinated across international borders, particularly in lower and middle income country settings. In this work, we describe mobility and the relationship between mobility and unfavorable TB treatment outcomes (i.e., death, loss to follow-up, or treatment failure) among a cohort of adults who initiated TB treatment at one of 12 health facilities near Lake Victoria. We abstracted data from health facility records for all 776 adults initiating TB treatment during a 6-month period at the selected facilities in Kenya, Tanzania, and Uganda. We interviewed 301 cohort members to assess overnight travel outside one's residential district/sub-county. In our analyses, we estimated the proportion of cohort members traveling in 2 and 6 months following initiation of TB treatment, explored correlates of mobility, and examined the association between mobility and an unfavorable TB treatment outcome. We estimated that 40.7% (95% CI: 33.3%, 49.6%) of people on treatment for TB traveled overnight at least once in the 6 months following treatment initiation. Mobility was more common among people who worked in the fishing industry and among those with extra-pulmonary TB. Mobility was not strongly associated with other characteristics examined, however, suggesting that efforts to improve TB care for mobile populations should be broad ranging. We found that in this cohort, people who were mobile were not at increased risk of an unfavorable TB treatment outcome. Findings from this study can help inform development and implementation of mobility-competent health services for people with TB in East Africa.

Under-Reporting of Tuberculosis Disease among Children and Adolescents in Low and Middle-Income Countries: A Systematic Review

Under-reporting of tuberculosis (TB) disease in children and adolescents is a significant global concern, as many children are missing from TB notification data. A systematic literature review was conducted to understand the global reporting gap of child and adolescent TB as well as current interventions to close this gap in Low- and Middle- Income Countries (LMIC). Our study found large and variable gaps in child and adolescent TB reporting, due to various factors. Interventions to close this gap exist but are limited. Future studies are necessary to improve global surveillance systems to improve TB care delivery for children and adolescents.

1451. Tuberculosis among Adults Aged 65 Years and Older—Alameda County, California, 2016–2019

Abstract Background Adults aged 65 years and older represent an increasing proportion of United States (U.S.) tuberculosis (TB) cases, and their clinical complexity creates unique issues for TB management. In Alameda County, California, we examined clinical characteristics and treatment outcomes among older adults with TB disease. Methods We evaluated demographic and clinical surveillance data from all adult TB cases in Alameda County during 2016–2019. We further reviewed public health department charts for TB cases among individuals aged 65 years and older to obtain more detailed information on co-morbidities, adverse effects, and treatment outcomes. Demographics, clinical characteristics, and outcomes were compared in younger adults (15-64) to older adults (≥ 65), who were further stratified by those aged 75 years and older. All comparisons were conducted using Fisher’s exact or Mann-Whitney U tests. Results Of 517 adult TB cases, 172 (33%) were older adults, and more likely to be male (68.6%), Asian (89.0%), non-U.S. born (98.3%), and have diabetes (32.6%) compared to younger adults (Table). At time of TB diagnosis, older adults were more likely than younger adults to have a negative interferon-gamma release assay result (24.6% vs. 16.0%, P=0.01), particularly among aged 75 years and older where 32.9% had a negative result. The majority of older adults with pulmonary TB had sputum smear-negative disease (58.9%) and 19.9% were culture- and polymerase chain reaction assay-negative. On anti-TB treatment, 32.5% of older adults experienced at least one adverse event, most commonly elevated liver enzymes (56.6%) and rash (32.1%). Older adults were more likely to be dead at diagnosis (3.5% vs. 0.0%, P=0.001), and were less likely to complete TB treatment (77.7% vs. 88.4% in younger adults, P=0.002), which was lowest among aged 75 years and older (72.9% vs. 84.3% in those 65-74, P=0.04). Death during treatment was higher in older adults, in particular aged 75 and older compared to 65–74 years (22.9% vs. 7.1%, P=0.01). Conclusion Older adults with TB disease faced several challenges, including negative diagnostic testing and poor treatment outcomes. A greater understanding of the presentation, adverse events and outcomes can guide interventions to improve TB care in this population. Disclosures All Authors: No reported disclosures.

Challenges on tuberculosis care in health care facilities during COVID-19 pandemic: Indonesian perspective.

Indonesia is among the top three countries globally with the highest tuberculosis burden. During the past decades, Indonesian health authorities have struggled to improve tuberculosis care quality in health care facilities by optimizing the regulation and strengthening the private sector contributions. The coronavirus disease 2019 (COVID-19) pandemic has hardly affected the Indonesian health care system, including the National Tuberculosis Control Program. While the end of the COVID-19 pandemic in Indonesia is uncertain, the measure to control tuberculosis must not be weakened. Early identification and measurement of the problem size are essential to decide the most appropriate approach to maintain the sustainability of National Tuberculosis Control Program, particularly in health care facilities during the COVID-19 pandemic. This article points out the possible threats to the sustainability of TB care in Indonesia during the COVID-19 pandemic, including some approaches to overcome those problems.

Tuberculosis care designed with barramarrany (family): Participatory action research that prioritised partnership, healthy housing and nutrition.

Issue addressed.Ongoing tuberculosis (TB) transmission in Aboriginal communities in Australia is unfair and unacceptable. Redressing the inequity in TB affecting Aboriginal peoples is a priority in Australia's Strategic Plan for Tuberculosis Control. Improving TB care needs not to just identify barriers but do something about them. Privileging the voices of Aboriginal people affected by TB is essential to identify effective and enabling strategies.MethodsA barramarrany (Aboriginal family) affected by recurring TB partnered with TB and Environmental Health teams using a participatory action research (PAR) methodology to improve housing health hardware and nutrition alongside biomedical TB prevention and care. A combination of the Ottawa Charter for Health Promotion; the International “End TB” Strategy; and Aboriginal barramarrany leadership, worldviews and traditional values guided actions to reduce TB transmission.ResultsTogether the partners improved housing hardware and access to nutritious food, so the barramarrany could create a setting for good health and wellbeing. These actions supported the barramarrany to regain the physical, social and emotional wellbeing to deal with day‐to‐day challenges and stresses. The barramarrany were able to better sustain supportive relationships; grow, prepare and eat healthy food; and participate in health care activities. The barramarrany could better engage with medical approaches for TB and four barramarrany members completed TB treatment. The PAR action‐project enabled and supported early TB diagnosis, treatment and prevention.ConclusionAmplifying the voices of Aboriginal people and shared ownership of TB diagnosis, treatment and prevention by the barramarrany, was underpinned with principles of self‐determination, capacity building and social justice. This PAR action‐project provides further evidence that improving housing and nutrition can assist in Ending TB while improving wellbeing.So what?Our action‐research project undertaken within a PAR framework demonstrates the implementation of End TB Strategies by utilising the Ottawa Charter's five actions to promote health, by understanding and centralising the social determinants of health.

Evaluation of implementation and effectiveness of digital adherence technology with differentiated care to support tuberculosis treatment adherence and improve treatment outcomes in Ethiopia: a study protocol for a cluster randomised trial

BackgroundDigital adherence technologies (DATs) are recommended to support patient-centred, differentiated care to improve tuberculosis (TB) treatment outcomes, but evidence that such technologies improve adherence is limited. We aim to implement and evaluate the effectiveness of smart pillboxes and medication labels linked to an adherence data platform, to create a differentiated care response to patient adherence and improve TB care among adult pulmonary TB participants. Our study is part of the Adherence Support Coalition to End TB (ASCENT) project in Ethiopia.Methods/DesignWe will conduct a pragmatic three-arm cluster-randomised trial with 78 health facilities in two regions in Ethiopia. Facilities are randomised (1:1:1) to either of the two intervention arms or standard of care. Adults aged ≥ 18 years with drug-sensitive (DS) pulmonary TB are enrolled over 12 months and followed-up for 12 months after treatment initiation. Participants in facilities randomised to either of the two intervention arms are offered a DAT linked to the web-based ASCENT adherence platform for daily adherence monitoring and differentiated response to patient adherence for those who have missed doses. Participants at standard of care facilities receive routine care. For those that had bacteriologically confirmed TB at treatment initiation and can produce sputum without induction, sputum culture will be performed approximately 6 months after the end of treatment to measure disease recurrence. The primary endpoint is a composite unfavourable outcome measured over 12 months from TB treatment initiation defined as either poor end of treatment outcome (lost to follow-up, death, or treatment failure) or treatment recurrence measured 6 months after the scheduled end of treatment. This study will also evaluate the effectiveness, feasibility, and cost-effectiveness of DAT systems for DS-TB patients.DiscussionThis trial will evaluate the impact and contextual factors of medication label and smart pillbox with a differentiated response to patient care, among adult pulmonary DS-TB participants in Ethiopia. If successful, this evaluation will generate valuable evidence via a shared evaluation framework for optimal use and scale-up.Trial registration: Pan African Clinical Trials Registry PACTR202008776694999, https://pactr.samrc.ac.za/TrialDisplay.aspx?TrialID=12241, registered on August 11, 2020.

Role of informal healthcare providers in tuberculosis care in low- and middle-income countries: A systematic scoping review.

Achieving targets set in the End TB Strategy is still a distant goal for many Low- and Middle-Income Countries (LMICs). The importance of strengthening public-private partnership by engaging all identified providers in Tuberculosis (TB) care has long been advocated in global TB policies and strategies. However, Informal Healthcare Providers (IPs) are not yet prioritised and engaged in National Tuberculosis Programs (NTPs) globally. There exists a substantial body of evidence that confirms an important contribution of IPs in TB care. A systematic understanding of their role is necessary to ascertain their potential in improving TB care in LMICs. The purpose of this review is to scope the role of IPs in TB care. The scoping review was guided by a framework developed by the Joanna Briggs Institute. An electronic search of literature was conducted in MEDLINE, EMBASE, SCOPUS, Global Health, CINAHL, and Web of Science. Of a total 5234 records identified and retrieved, 92 full-text articles were screened, of which 13 were included in the final review. An increasing trend was observed in publication over time, with most published between 2010-2019. In 60% of the articles, NTPs were mentioned as a collaborator in the study. For detection and diagnosis, IPs were primarily involved in identifying and referring patients. Administering DOT (Directly Observed Treatment) to the patient was the major task assigned to IPs for treatment and support. There is a paucity of evidence on prevention, as only one study involved IPs to perform this role. Traditional health providers were the most commonly featured, but there was not much variation in the role by provider type. All studies reported a positive role of IPs in improving TB care outcomes. This review demonstrates that IPs can be successfully engaged in various roles in TB care with appropriate support and training. Their contribution can support countries to achieve their national and global targets if prioritized in National TB Programs.

Impact of peer-trainer leadership style on uptake of a peer led educational outreach intervention to improve tuberculosis care and outcomes in Malawi: a qualitative study

BackgroundLittle is known about how to build leadership capacity to support implementation of evidence-based practices within health systems. We observed substantial variability across sites in uptake and sustainability of a peer-led educational outreach intervention for lay health workers (LHWs) providing tuberculosis care in Malawi. Feedback from peer-trainers (PTs) suggested that leadership may have contributed to the variation. We sought to assess the impact of PT leadership style on implementation, and to identify leadership traits of more successful PTs, to inform future implementation planning and to identify targets for leadership capacity building.MethodsQualitative study employing interviews with PTs and LHWs at high and low implementation sites, and review of study team and quarterly PT meeting notes. High implementation sites achieved high uptake, sustainability and fidelity of implementation including: close adherence to training content and process, high levels of coverage (training most or all eligible LHWs at their site), and outcomes were achieved with high levels of self reported competence with the intervention among both PTs and LHWs. Low implementation sites achieved limited coverage (<= 50% of LHWs trained), and intervention fidelity.ResultsEight PTs and 10 LHWs from eight high and 10 low implementation sites participated in interviews. Leadership traits of more successful PTs included: flexibility in their approach to training, role modeling and provision of supportive supervision to support learning; addressing challenges proactively and as they occurred; collaborative planning; knowledgeable; and availability to support implementation. Traits unique to less successful PTs included: a poor attitude toward their role as PT and a passive-avoidant approach to challenges.ConclusionThis study identified leadership traits more common among unit level leaders at sites with higher uptake, sustainability, and fidelity of implementation. These findings provide a starting point for development and evaluation of a leadership capacity building intervention for unit level leaders to support implementation.

An Innovative Public-Private Mix Model for Improving Tuberculosis Care in Vietnam: How Well are We Doing?

To improve tuberculosis (TB) care among individuals attending a private tertiary care hospital in Vietnam, an innovative private sector engagement model was implemented from June to December 2018. This included: (i) Active facility-based screening of all adults for TB symptoms (and chest x-ray (CXR) for those with symptoms) by trained and incentivized providers, with on-site diagnostic testing or transport of sputum samples, (ii) a mobile application to reduce dropout in the care cascade and (iii) enhanced follow-up care by community health workers. We conducted a cohort study using project and routine surveillance data for evaluation. Among 52,078 attendees, 368 (0.7%) had symptoms suggestive of TB and abnormalities on CXR. Among them, 299 (81%) were tested and 103 (34.4%) were diagnosed with TB. In addition, 195 individuals with normal CXR were indicated for TB testing by attending clinicians, of whom, seven were diagnosed with TB. Of the 110 TB patients diagnosed, 104 (95%) were initiated on treatment and 97 (93%) had a successful treatment outcome. Given the success of this model, the National TB Programme is considering to scale it up nationwide after undertaking a detailed cost-effectiveness analysis.

Community Contribution to Tuberculosis Care in the Krachi West District of Ghana: A Qualitative Study.

Background Eradicating tuberculosis (TB) is one of the targets of the recently constituted Sustainable Development Goal (SDG) Three. In the light of limitations inherent in prevailing tuberculosis care and the global urgency to improve TB care, decentralising TB care beyond health facilities by harnessing the contribution of communities is essential in ensuring effective tuberculosis care. In this paper, we explored community contribution to TB care in the Krachi West District of Ghana. Methods In this qualitative study, 24 TB stakeholders made up of 7 health workers, 9 tuberculosis patients, 4 community health volunteers, 2 treatment supporters, and 2 opinion leaders were interviewed. Data collected were analysed manually, but thematically. Statements of the participants were presented as quotes to substantiate issues discussed. Results Community contribution to TB care was low. Most of the community members were not aware of any community level activity towards tuberculosis care. Though patients were mainly the ones responsible for the selection of their treatment supporters, there were instances where health workers selected supporters for them without their consent. Some treatment supporters were also not given any education concerning their roles in supporting their patients, resulting in some patients defaulting treatment and others taking their medications wrongfully. Conclusion Our study revealed low community involvement in tuberculosis care in the Krachi West District of Ghana. Community sensitisation on the World Health Organisation's Directly Observed Treatment Strategy (which Ghana adopted in 1994) to increase community involvement in tuberculosis activities is, therefore, recommended.

Tuberculosis diagnostic and treatment practices in private sector: Implementation study in an Indian city

SettingImplementation study in private health facilities in an Indian metropolis. ObjectivesImprove Tuberculosis (TB) care by private practitioners (PPs). MethodsPPs from a defined city area were imparted short training in TB care and linkages made with public facilities; subsequent practices were recorded. ResultsOf 364 presumptive TB patient records, 70 (19.3%) did not conform to its definition. Of the conforming, 174 (59.2%) had presumptive pulmonary TB (PTB), 53 (18%) presumptive extra-pulmonary (EPTB) and 67 (24%) had both. Of conforming presumptive PTB, most underwent Chest X-ray and sputum examination in private laboratories. Tissue based diagnostics were not advised for most presumptive EPTB patients. Of 101 cases diagnosed with TB, 82% were new, 23% known diabetic and 4.7% human immune deficiency virus (HIV) reactive out of 64 tested. Most were notified and initiated treatment within 15 days of diagnosis. One-fourth was prescribed standard treatment regimen and treatment was not directly observed for most. One third was initial defaulters or lost during treatment; 62% of PTB and 46% EPTB cases initiated on treatment in private were successfully treated. Of successfully treated PTB cases, 61% had undergone follow-up sputum examination. ConclusionMuch intensified support mechanisms are needed to improve TB care in private sector.

Modelling the impact of social protection on tuberculosis: the S-PROTECT project

BackgroundTackling the social determinants of Tuberculosis (TB) through social protection is a key element of the post-2015 End TB Strategy. However, evidence informing policies are still scarce. Mathematical modelling has the potential to contribute to fill this knowledge gap, but existing models are inadequate. The S-PROTECT consortium aimed to develop an innovative mathematical modelling approach to better understand the role of social protection to improve TB care, prevention and control.MethodsS-PROTECT used a three-steps approach: 1) the development of a conceptual framework; 2) the extraction from this framework of three high-priority mechanistic pathways amenable for modelling; 3) the development of a revised version of a standard TB transmission model able to capture the structure of these pathways. As a test case we used the Bolsa Familia Programme (BFP), the Brazilian conditional cash transfer scheme.ResultsAssessing one of these pathways, we estimated that BFP can reduce TB prevalence by 4% by improving households income and thus their nutritional status. When looking at the direct impact via malnutrition (not income mediated) the impact was 33%. This variation was due to limited data availability, uncertainties on data transformation and the pathway approach taken. These results are preliminary and only aim to serve as illustrative example of the methodological challenges encountered in this first modelling attempt, nonetheless they suggest the potential added value of integrating TB standard of care with social protection strategies.ConclusionsResults are to be confirmed with further analysis. However, by developing a generalizable modelling framework, S-PROTECT proved that the modelling of social protection is complex, but doable and allowed to draw the research road map for the future in this field.

Mobile phone interventions for tuberculosis should ensure access to mobile phones to enhance equity - a prospective, observational cohort study in Peruvian shantytowns.

ObjectivesMobile phone interventions have been advocated for tuberculosis care, but little is known about access of target populations to mobile phones. We studied mobile phone access among patients with tuberculosis, focusing on vulnerable patients and patients who later had adverse treatment outcomes.MethodsIn a prospective cohort study in Callao, Peru, we recruited and interviewed 2584 patients with tuberculosis between 2007 and 2013 and followed them until 2016 for adverse treatment outcomes using national treatment registers. Subsequently, we recruited a further 622 patients between 2016 and 2017. Data were analysed using logistic regression and by calculating relative risks (RR).ResultsBetween 2007 and 2013, the proportion of the general population of Peru without mobile phone access averaged 7.8% but for patients with tuberculosis was 18% (P < 0.001). Patients without access were more likely to hold a lower socioeconomic position, suffer from food insecurity and be older than 50 years (all P < 0.01). Compared to patients with mobile phone access, patients without access at recruitment were more likely to subsequently have incomplete treatment (20% vs. 13%, RR = 1.5; P = 0.001) or an adverse treatment outcome (29% vs. 23% RR = 1.3; P = 0.006). Between 2016 and 2017, the proportion of patients without access dropped to 8.9% overall, but remained the same (18%) as in 2012 among the poorest third.ConclusionAccess to mobile phones among patients with tuberculosis is insufficient, and rarest in patients who are poorer and later have adverse treatment outcomes. Thus, mobile phone interventions to improve tuberculosis care may be least accessed by the priority populations for whom they are intended. Such interventions should ensure access to mobile phones to enhance equity.
