Durations and Delays in Care Seeking, Diagnosis and Treatment Initiation in Uncomplicated Pulmonary Tuberculosis Patients in Mumbai, India

Healthcare seeking behavior and delays in case of Drug-Resistant Tuberculosis patients in Bangladesh: Findings from a cross-sectional survey

The emergence of Drug-Resistant Tuberculosis (DR-TB) has become a major threat globally and Bangladesh is no exception. Delays in healthcare seeking, proper diagnosis and initiation of treatment cause continuous transmission of the resistant tubercule bacilli through the communities. This study aimed to assess the different health care-seeking behaviors and delays among DR-TB patients in Bangladesh. A prospective cross-sectional study was conducted from November to December 2018, among 92 culture positive and registered DR-TB patients in four selected hospitals in Bangladesh. Data were collected through face-to-face interviews with survey questionnaire as well as record reviews. Among the 92 study participants, the median patient delay was 7 (IQR 3, 15) days, the median diagnostic delay was 88 (IQR 36.5, 210), the median treatment delay was 7 (IQR 4,12) days, and the median total delay among DR-TB patients was 108.5 (IQR 57.5, 238) days. 81.32% sought initial care from informal healthcare providers. The majority (68.48%) of the informal healthcare providers were drug sellers while 60.87% of patients sought care from more than four healthcare points before being diagnosed with DR-TB. The initial care seeking from multiple providers was associated with diagnostic and total delays. In Bangladesh, DR-TB cases usually seek care from multiple providers, particularly from informal providers, and among them, alarmingly higher healthcare-seeking related delays were noted. Immediate measures should be taken both at the health system levels and, in the community, to curb transmission and reduce the burden of the disease.

The Extent of Delay in Diagnosis, Treatment and their Associated Factors among Tuberculosis Patients Attending Government Hospitals of Rishikesh, Uttarakhand: A Cross-Sectional Study

BACKGROUND

"Tuberculosis (TB) remains a major public health problem" worldwide, affecting almost all age groups. "Early diagnosis and prompt treatment are essential to significantly reducing the TB burden." However, a significant proportion of cases remain undiagnosed and untreated, which plays a vital role in the transmission of the disease and severity of the illness in the community in most developing countries.

AIMS & OBJECTIVES

This study aimed to assess "the extent of delay in diagnosis and treatment of TB patients" and to identify the major factors associated with such delays (whether patient or health system-related) among TB patients in Rishikesh.

METHODS

This descriptive cross-sectional study was conducted in Rishikesh Town, Dehradun District, Uttara khand, India. Total of 130 newly diagnosed TB patients were recruited as study participants who attended the government hospitals of Rishikesh, All India Institute of Medical Sciences, Rishikesh and S P S Government Hospital, Rishikesh. A universal sampling technique was used in this study.

RESULTS

The mean age of the study participant was 36.75 (Standard Deviation (SD), 17.6), and the median age was 34 years. Of the patients, 64.6% were men, and 35.4% were women. The extent of various delays, such as patient delay (median 16 days), diagnostic delay (median 78.5 days), treatment delay (median 4 days), health system delay (43 days), and total delay (median 81 days).

CONCLUSION

The misconception of any chronic disease may lead to a false diagnosis or long treatment for symptomatic relief; the absence of proper diagnostic tests and doctor shopping could be the reasons for the prolonged diagnostic delay. Therefore, by strengthening the collaboration between private and public practitioners in order to meet the expectations of the Government of India to achieve the goals of the "National Strategic Plan for ending TB" in India by providing good quality care for all patients.

Missed opportunity for tuberculosis screening among patients presenting at two health facilities in Manafwa district, Uganda

Missed opportunities for Tuberculosis (TB) screening are key drivers of continued tuberculosis transmission. To determine the proportion of and factors associated with missing TB screening amongst patients who attended Bubulo and Butiru health facilities in the Manafwa district to inform future TB prevention and control efforts in Uganda. This was a facility-based, cross-sectional study with quantitative methods of data collection. 125 patients (≥18 years) with at least one symptom suggestive of TB were systematically selected and interviewed at the exit. Data analysis was done by Stata version 15, using a cluster-based logistic regression model. Of the 125 patients enrolled at both sites, 39% (n=49) were aged between 30 and 49 years; 75.2% (n=94) were females; 44% (n=55) were married while 66.4% (n=83) had a primary level of education. Of the patients enrolled in the study, 68% (n=85) had a missed opportunity for TB screening. Having a; post-primary education level (Adjusted Odds Ratio [AOR]=5.9; 95% Confidence Interval [95% CI]=1.3, 27.1) and attending Bubulo HCIV (AOR=0.01; 95% CI: 0.01, 0.2) were significantly associated with having a missed opportunity for TB screening. Our findings show that slightly more than two-thirds of the patients who presented to the study health facilities with symptoms suggestive of TB missed the opportunity to be screened for TB. Study findings suggest a need for interventions to increase TB screening, particularly among better-educated TB patients.

Tuberculosis diagnostic and treatment delays among patients in Uganda

Background

Mycobacterium tuberculosis, a bacterium that relies on its human host to achieve airborne transmission and existence, is the primary cause of tuberculosis (TB), a disease that is vital to public health.

Aim

To update the society on tuberculosis diagnostic and treatment delays among patients in Uganda.

Materials and Methods

The review paper utilized different search engines, such as Pubmed Central, Scopus, Web of Science, Google Scholar, and so forth, to conduct this review paper.

Results

Delays in diagnosis could cause diseases to spread throughout the community, progress more quickly, and increase mortality. With many populations experiencing TB diagnostic delay and less than a third of the population experiencing TB treatment delay, the rates of tuberculosis diagnosis and treatment delays are high.

Conclusion

The delay in diagnosing and treating tuberculosis in men is positively correlated with knowledge of the disease's symptoms and the regular use of a handkerchief or both hands to cover the mouth and nose while coughing or sneezing.

Meeting the 2030 END TB goals in the wake of COVID-19: A modelling study of countries in the USAID TB portfolio

Progress towards the 2030 End TB goals has seen severe setbacks due to disruptions arising from the COVID-19 pandemic. For governments and international partner organizations supporting the global TB response, there is a need to assess what level of effort is now needed to reach these goals. Using mathematical modelling, we addressed this question for the countries being supported by the United States Agency for International Development (USAID). We aggregated the 24 countries in the USAID portfolio into three geographical country groups: South Asia; sub-Saharan Africa; and Central Asian Republics/Europe (CAR/EU). From 2023 onwards we modelled a combination of interventions acting at different stages of the care cascade, including improved diagnostics; reducing the patient care seeking delay; and the rollout of a disease-preventing vaccine from 2025 onwards. We found that in all three country groups, meeting the End TB goals by 2030 will require a combination of interventions acting at stages of the TB care cascade. Specific priorities may depend on country settings, for example with public-private mix playing an important role in countries in South Asia and elsewhere. When a vaccine becomes available, its required coverage to meet the 2030 goals will vary by setting, depending on the amount of preventive therapy that has already been implemented. Monitoring the number-needed-to-test to identify 1 person with TB in community settings can provide a useful measure of progress towards the End TB goals.

Intersections of informal work status, gender and tuberculosis diagnosis: Insights from a qualitative study from an Indian setting

BACKGROUND

There is evidence that more than one third of tuberculosis (TB) cases in India go undiagnosed each year and it is more pronounced among female patients. While there are studies available on the socioeconomic, cultural and gender-related dimensions of TB diagnosis delays among female patients in India, intersections of gender, informal work and diagnosis delays are not sufficiently studied. The present study aims to fill this gap by examining the TB diagnosis delay that are linked to the contingencies of working in informal arrangements for women from lower socio economic background.

METHODS

The study draws on 80 qualitative in-depth interviews conducted among female patients from lower socio-economic background, who were working or recently stopped working in informal arrangements and undergoing Directly Observed Therapy, Short-course (DOTS) treatment in Bengaluru (India) city and 60 willing significant others of the patients. The participants were identified through a scoping survey that covered 188 female patients from 18 DOTS centres in the city.

FINDINGS

Other than the already known reasons for the delay in TB diagnosis for women such as normalisation of symptoms, stigma and the gender-related discrimination leading to low prioritisation of women's illness, the present study identifies reasons related to work informality. These are normalisation of symptoms as workplace health problems; work related concerns that restricted formal help seeking; non TB specific narratives of symptoms, often incorrectly assumed to be work related health issues or comorbidities and thus confounding the early accurate diagnosis by the medical personnel and shifting between formal and informal systems of help-seeking. Further, the study found that mere knowledge of TB symptoms did not always translate to early diagnosis for patients from the lower socioeconomic groups working in informal arrangements due to the fear of losing work and wages owing to hospital visits.

CONCLUSIONS

The workplace focus, especially the informal sector where a huge majority of India's workforce is employed, is notably absent in the TB elimination programme. The study indicates the need to adopt a comprehensive approach in the ongoing TB elimination programme in India in which family, living environment and workplace should be integral parts.

Use of standardised patients to assess tuberculosis case management by private pharmacies in Patna, India: A repeat cross-sectional study

As the first point of care for many healthcare seekers, private pharmacies play an important role in tuberculosis (TB) care. However, previous studies in India have showed that private pharmacies commonly dispense symptomatic treatments and broad-spectrum antibiotics over-the-counter (OTC), rather than referring patients for TB testing. Such inappropriate management by pharmacies can delaye TB diagnosis. We assessed medical advice and OTC drug dispensing practices of pharmacists for standardized patients presenting with classic symptoms of pulmonary TB (case 1) and for those with sputum smear positive pulmonary TB (case 2), and examined how practices have changed over time in an urban Indian site. We examined how and whether private pharmacies improved practices for TB in 2019 compared to a baseline study conducted in 2015 in the city of Patna, using the same survey sampling techniques and study staff. The proportion of patient-pharmacist interactions that resulted in correct or ideal management, as well as the proportion of interactions resulting in antibiotic, quinolone, and corticosteroid are presented, with standard errors clustered at the provider level. To assess the difference in case management and the use of drugs across the two cases by round, a difference in difference (DiD) model was employed. A total of 936 SP interactions were completed over both rounds of survey. Our results indicate that across both rounds of data collection, 331 of 936 (35%; 95% CI: 32-38%) of interactions were correctly managed. At baseline, 215 of 500 (43%; 95% CI: 39-47%) of interactions were correctly managed whereas 116 of 436 (27%; 95% CI: 23-31%) were correctly managed in the second round of data collection. Ideal management, where in addition to a referral, patients were not prescribed any potentially harmful medications, was seen in 275 of 936 (29%; 95% CI: 27-32%) of interactions overall, with 194 of 500 (39%; 95% CI: 35-43%) of interactions at baseline and 81 of 436 (19%; 95% CI: 15-22%) in round 2. No private pharmacy dispensed anti-TB medications without a prescription. On average, the difference in correct case management between case 1 vs. case 2 dropped by 20 percent points from baseline to the second round of data collection. Similarly, ideal case management decreased by 26 percentage points between rounds. This is in contrast with the dispensation of medicines, which had the opposite effect between rounds; the difference in dispensation of quinolones between case 1 and case 2 increased by 14 percentage points, as did corticosteroids by 9 percentage points, antibiotics by 25 percentage points and medicines generally by 30 percentage points. Our standardised patient study provides valuable insights into how private pharmacies in an Indian city changed their management of patients with TB symptoms or with confirmed TB over a 5-year period. We saw that overall, private pharmacy performance has weakened over time. However, no OTC dispensation of anti-TB medications occurred in either survey round. As the first point of contact for many care seekers, continued and sustained efforts to engage with Indian private pharmacies should be prioritized.

Tuberculosis diagnosis and management in the public versus private sector: a standardised patients study in Mumbai, India

BACKGROUND

There are few rigorous studies comparing quality of tuberculosis (TB) care in public versus private sectors.

METHODS

We used standardised patients (SPs) to measure technical quality and patient experience in a sample of private and public facilities in Mumbai.

RESULTS

SPs presented a 'classic, suspected TB' scenario and a 'recurrence or drug-resistance' scenario. In the private sector, SPs completed 643 interactions. In the public sector, 164 interactions. Outcomes included indicators of correct management, medication use and client experience. Public providers used microbiological testing (typically, microscopy) more frequently, in 123 of 164 (75%; 95% CI 68% to 81%) vs 223 of 644 interactions (35%; 95% CI 31% to 38%) in the private sector. Private providers were more likely to order chest X-rays, in 556 of 639 interactions (86%; 95% CI 84% to 89%). According to national TB guidelines, we found higher proportions of correct management in the public sector (75% vs 35%; (adjusted) difference 35 percentage points (pp); 95% CI 25 to 46). If X-rays were considered acceptable for the first case but drug-susceptibility testing was required for the second case, the private sector correctly managed a slightly higher proportion of interactions (67% vs 51%; adjusted difference 16 pp; 95% CI 7 to 25). Broad-spectrum antibiotics were used in 76% (95% CI 66% to 84%) of the interactions in public hospitals, and 61% (95% CI 58% to 65%) in private facilities. Costs in the private clinics averaged rupees INR 512 (95% CI 485 to 539); public facilities charged INR 10. Private providers spent more time with patients (4.4 min vs 2.4 min; adjusted difference 2.0 min; 95% CI 1.2 to 2.9) and asked a greater share of relevant questions (29% vs 43%; adjusted difference 13.7 pp; 95% CI 8.2 to 19.3).

CONCLUSIONS

While the public providers did a better job of adhering to national TB guidelines (especially microbiological testing) and offered less expensive care, private sector providers did better on client experience.

Gaps and Interventions across the Diagnostic Care Cascade of TB Patients at the Level of Patient, Community and Health System: A Qualitative Review of the Literature

Tuberculosis (TB) continues to be one of the important public health concerns globally, and India is among the seven countries with the largest burden of TB. There has been a consistent increase in the notifications of TB cases across the globe. However, the 2018 estimates envisage a gap of about 30% between the incident and notified cases of TB, indicating a significant number of patients who remain undiagnosed or ‘missed’. It is important to understand who is ‘missed’, find this population, and provide quality care. Given these complexities, we reviewed the diagnostic gaps in the care cascade for TB. We searched Medline via PubMed and CENTRAL databases via the Cochrane Library. The search strategy for PubMed was tailored to individual databases and was as: ((((((tuberculosis[Title/Abstract]) OR (TB[Title/Abstract])) OR (koch *[Title/Abstract])) OR (“tuberculosis”[MeSH Terms]))) AND (((diagnos *) AND (“diagnosis”[MeSH Terms])))). Furthermore, we screened the references list of the potentially relevant studies to seek additional studies. Studies retrieved from these electronic searches and relevant references included in the bibliography of those studies were reviewed. Original studies in English that assessed the causes of diagnostic gaps and interventions used to address them were included. Delays in diagnosis were found to be attributable to both the individuals’ and the health system’s capacity to diagnose and promptly commence treatment. This review provides insights into the diagnostic gaps in a cascade of care for TB and different interventions adopted in studies to close this gap. The major diagnostic gaps identified in this review are as follows: people may not have access to TB diagnostic tests, individuals are at a higher risk of missed diagnosis, services are available but people may not seek care with a diagnostic facility, and patients are not diagnosed despite reaching health facilities. Therefore, reaching the goal to End TB requires putting in place models and methods to provide prompt and quality assured diagnosis to populations at par.

Review on public private mix TB control strategy in India

In India, around 70% of health care services are offered by the private sector. National strategic plan (NSP) has emphasized private sector engagement to TB program. Public private mix strategy along with web based mandatory notification of TB cases were established in 2002. However, feasibility of consulting an informal provider first was seen to be associated with significant increases in total delay (absolute increase 22.8 days, 95%CI 6.2-39.5) and in the risk of prolonged delay >90 days.

STUDY DESIGN

A mixed method literature review, descriptive information and evaluative outcomes data extracted and analysed.

OBJECTIVE

This review aimed to systematically review public private mix strategy in TB control in Indian tuberculosis disease burden and efforts towards elimination.

METHODS

Available published literatures were searched with key words, articles related with objectives were selected, analysed and systematically synthesized. Overall 30 studies were reviewed.

RESULT

Available literatures were selected based on study objective and analysed. The modes of PPM strategy its success and problems of implementation and shortcomings were synthesized.

DISCUSSION

After implementing PPM from 2002, case detection is seen to have significantly increased for smear positive cases and high detection rate and better treatment outcomes achieved. However, implementation of PPM has been challenged to fully deliver the intended services. Interestingly, seeking initial care from PPs is significant risk factor for diagnostic delay.

CONCLUSION

PPM is a proven and tested strategy to achieve End TB goal globally and even in India. However, studies indicated there is the need to strengthen and motivate public sector to engage private practitioners in specific districts and sync their activities into the mainstream programme. Conflict of interest and mistrust between private practitioners and public sector has to be well addressed to build sustainable relationship among the sectors. Routine and institutionalized systematic monitoring and evaluation of the system is required to meet the End TB goal by 2025.

Acceptability of video observed treatment vs. directly observed treatment for tuberculosis: a comparative analysis between South and Central India

Background Directly Observed Treatment (DOT) is a requirement in the management of Tuberculosis (TB) globally. With the transition from alternate day treatment to daily treatment in India, monitoring treatment adherence through DOT is a logistic challenge. The pervasiveness of mobile phones in India provides a unique opportunity to address this challenge remotely. This study was designed to compare the acceptability of mobile phones for antitubercular treatment (ATT) support in two distinct regions of India. Methodology This was a cross-sectional exploratory study that enrolled 351 patients with TB, of whom 185 were from Bangalore, South India, and 166 from Ujjain, Central India. Trained research assistants administered a pretested questionnaire comprising demographics, phone usage patterns, and acceptability of mobile phone technology to support treatment adherence to TB medicines.  Results The mean age of the 351 participants was 32±13.6 years of whom 140 (40%) were women. Of the participants, 259 (74%) were urban, 221 (63%) had >4 years of education. A significantly greater number of participants were newly diagnosed with TB and were in the intensive phase of treatment. Overall, 218 (62%) preferred vDOT over DOT. There was an overall difference in preference between the two sites which is explained by differences in socio-economic variables. Conclusion Mobile phone adherence support is acceptable to patients on Antitubercular treatment ATT with minor variations in design based on demographic and cultural differences. In India, the preference for voice calls over text messages/SMS while designing mHealth interventions cannot be ignored. Of importance is the preference for DOT over vDOT in central India, unlike South India. However, in time, the expanding use of mobile technology supplemented with counseling, could overcome the barriers of privacy and stigma and promote the transition from in-person DOT to vDOT or mobile phone adherence monitoring and support for ATT in India.

Total, Patient and System Diagnostic Delays for Pulmonary Bacilliferous Tuberculosis in the Six Diagnostic and Treatment Centers in the Five Health Districts of the Central Region, Burkina Faso, 2018

Introduction

Long diagnosis delay contributes significantly to the failure to eradicate tuberculosis. The objective of this study was to evaluate the total, patient and system delays in diagnosis of pulmonary bacilliferous in the six tuberculosis Diagnostic and Treatment Centers in the five health districts of the central region in Burkina Faso.

Methods

A descriptive cross-sectional study was conducted among 384 microscopy-positive pulmonary tuberculosis patients in 2018 to address this objective. It concerned the socio-demographic, clinical, microbiological characteristics, and referral location/pathway characteristics of the patients. We then calculated the different delays. The “patient” (time from first symptoms to first consultation), “system” (time from first consultation to first diagnosis) and total (time from first symptoms to diagnosis) median diagnostic delay were estimated.

Results

The median “total”, “patient” and “system” diagnostic times were 37, 21 and 7 days, respectively. Of the 384 patients surveyed, 158 patients or 41.25% of patients had a long total diagnostic delay (> 45 days). The number of patients with a long system diagnostic delay was 125 patients (32.55%; p < 0.001) and those with a long patient diagnostic delay were 105 patients (27.34%; p < 0.001).

Conclusion

The total diagnosis delay of pulmonary tuberculosis was long for almost half of the patients. Awareness of the signs of tuberculosis among patients and caregivers, and consultation in a health center must be intensified to help considerably reduce these delays.

Achieving a "step change" in the tuberculosis epidemic through comprehensive community-wide intervention: a model-based analysis

BACKGROUND

Global progress towards reducing tuberculosis (TB) incidence and mortality has consistently lagged behind the World Health Organization targets leading to a perception that large reductions in TB burden cannot be achieved. However, several recent and historical trials suggest that intervention efforts that are comprehensive and intensive can have a substantial epidemiological impact. We aimed to quantify the potential epidemiological impact of an intensive but realistic, community-wide campaign utilizing existing tools and designed to achieve a "step change" in the TB burden.

METHODS

We developed a compartmental model that resembled TB transmission and epidemiology of a mid-sized city in India, the country with the greatest absolute TB burden worldwide. We modeled the impact of a one-time, community-wide screening campaign, with treatment for TB disease and preventive therapy for latent TB infection (LTBI). This one-time intervention was followed by the strengthening of the tuberculosis-related health system, potentially facilitated by leveraging the one-time campaign. We estimated the tuberculosis cases and deaths that could be averted over 10 years using this comprehensive approach and assessed the contributions of individual components of the intervention.

RESULTS

A campaign that successfully screened 70% of the adult population for active and latent tuberculosis and subsequently reduced diagnostic and treatment delays and unsuccessful treatment outcomes by 50% was projected to avert 7800 (95% range 5450-10,200) cases and 1710 (1290-2180) tuberculosis-related deaths per 1 million population over 10 years. Of the total averted deaths, 33.5% (28.2-38.3) were attributable to the inclusion of preventive therapy and 52.9% (48.4-56.9) to health system strengthening.

CONCLUSIONS

A one-time, community-wide mass campaign, comprehensively designed to detect, treat, and prevent tuberculosis with currently existing tools can have a meaningful and long-lasting epidemiological impact. Successful treatment of LTBI is critical to achieving this result. Health system strengthening is essential to any effort to transform the TB response.

Duration and determinants of delayed tuberculosis diagnosis and treatment in high-burden countries: a mixed-methods systematic review and meta-analysis

BACKGROUND

Thirty countries with the highest tuberculosis (TB) burden bear 87% of the world's TB cases. Delayed diagnosis and treatment are detrimental to TB prognosis and sustain TB transmission in the community, making TB elimination a great challenge, especially in these countries. Our objective was to elucidate the duration and determinants of delayed diagnosis and treatment of pulmonary TB in high TB-burden countries.

METHODS

We conducted a systematic review and meta-analysis of quantitative and qualitative studies by searching four databases for literature published between 2008 and 2018 following PRISMA guidelines. We performed a narrative synthesis of the covariates significantly associated with patient, health system, treatment, and total delays. The pooled median duration of delay and effect sizes of covariates were estimated using random-effects meta-analyses. We identified key qualitative themes using thematic analysis.

RESULTS

This review included 124 articles from 14 low- and lower-middle-income countries (LIC and LMIC) and five upper-middle-income countries (UMIC). The pooled median duration of delays (in days) were-patient delay (LIC/LMIC: 28 (95% CI 20-30); UMIC: 10 (95% CI 10-20), health system delay (LIC/LMIC: 14 (95% CI 2-28); UMIC: 4 (95% CI 2-4), and treatment delay (LIC/LMIC: 14 (95% CI 3-84); UMIC: 0 (95% CI 0-1). There was consistent evidence that being female and rural residence was associated with longer patient delay. Patient delay was also associated with other individual, interpersonal, and community risk factors such as poor TB knowledge, long chains of care-seeking through private/multiple providers, perceived stigma, financial insecurities, and poor access to healthcare. Organizational and policy factors mediated health system and treatment delays. These factors included the lack of resources and complex administrative procedures and systems at the health facilities. We identified data gaps in 11 high-burden countries.

CONCLUSIONS

This review presented the duration of delays and detailed the determinants of delayed TB diagnosis and treatment in high-burden countries. The gaps identified could be addressed through tailored approaches, education, and at a higher level, through health system strengthening and provision of universal health coverage to reduce delays and improve access to TB diagnosis and care.

Contributing Factors in the Tuberculosis Care Cascade in India: A Systematic Literature Review

Tuberculosis (TB) care cascade is a recently evolved care model for patient retention across the sequential stages of care for a successful treatment outcome. The care cascade is multi-folded and complex in setting where the health system is reforming for its resilience. India, one of the countries with the highest burden of tuberculosis mortality and morbidity, is not an exception to this complexity. With the diverse challenges in the Indian health system and societal diversity, it is essential to understand the factors contributing to this TB care cascade. Thus, this study aims to map all the contributing factors to the TB care cascade in India. Further, it also captures the different patterns of factors explored so far in different countries’ regions. This systematic literature review was conducted between October 2020 and February 2021 in India using PubMed databases, Web of Science, and Google Scholar. Two reviewers extracted the data from eligible studies to summarize and tabulate important findings. Data were extracted and tabulated for study design, location of the study, type of TB patients, methodological approach, system side challenges, and demand-side challenges in the study’s findings. Out of 692 initial hits from the literature search, 28 studies were finally included to synthesize evidence in this review as per the inclusion and exclusion criteria. This review provides an insight into different factors such as the system-side (health workforce, institutional) and the demand-side (individual, societal) contributing towards the care cascade. The prime factors reflected in most of the studies were socio-economic condition, disease awareness, myths/beliefs, addictions among the demand-side factors and accessibility, the attitude of the healthcare staff, delay in referral for diagnosis among the system-side factors. The accountability for addressing these diverse factors is recommended to close the gaps in the TB care cascade.

Community health workers augment the cascade of TB detection to care in urban slums of two metro cities in India

Background

Tuberculosis Health Action Learning Initiative (THALI) funded by USAID is a person-centered initiative, supporting vulnerable urban populations to gain access to TB services. THALI trained and placed 112 Community health workers (CHWs) to detect and support individuals with TB symptoms or disease within urban slums in two cities, Hyderabad and Bengaluru, covering a population of about 3 million.

Methods

CHWs visited the slums once in a fortnight. They conducted TB awareness activities. They referred individuals with TB symptoms for sputum testing to nearest public sector laboratories. They visited those testing TB positive, once a fortnight in the intensive phase, and once a month thereafter. They supported TB patients and families with counselling, contact screening and social scheme linkages. They complemented the shortfall in urban TB government field staff numbers and their capacity to engage with TB patients. Data on CHWs’ patient referral for TB diagnosis and treatment support activities was entered into a database and analyzed to examine CHWs’ role in the cascade of TB care. We compared achievements of six monthly referral cohorts from September 2016 to February 2019.

Results

Overall, 31 617 (approximately 1%) of slum population were identified as TB symptomatic and referred for diagnosis. Among the referred persons, 23 976 (76%) underwent testing of which 3841 (16%) were TB positive. Overall, 3812 (99%) were initiated on treatment and 2760 (72%) agreed for regular follow up by the CHWs. Fifty-seven percent of 2952 referred were tested in the first cohort, against 86% of 8315 in the last cohort. The annualized case detection rate through CHW referrals in Bengaluru increased from 5.5 to 52.0 per 100 000 during the period, while in Hyderabad it was 35.4 initially and increased up to 118.9 per 100 000 persons. The treatment success rate was 87.1% among 193 in the first cohort vs 91.3% among 677 in the last cohort.

Conclusions

CHWs in urban slums augment TB detection to care cascade. Their performance and TB treatment outcomes improve over time. It would be important to examine the cost per TB case detected and successfully treated.

Pathways to diagnosis of pediatric TB patients: A mixed methods study from India

BACKGROUND

A significant proportion of pediatric tuberculosis (TB) patients go unnotified due to the challenges in diagnosis of TB among children. The experiences of this vulnerable group while going through the TB care cascade remain largely undocumented. The aim of this study was to explore the experiences of pediatric TB patients and families along the pathway to TB diagnosis and appropriate treatment in four cities of India.

METHODS

The study used a mixed methods, single phased, embedded design. The primary qualitative and secondary quantitative data were collected simultaneously by interviewing families of 100 randomly selected Xpert MTB/RIF positive pediatric TB patients, under the pediatric TB project, in 4 Indian cities using a semi-structured questionnaire. The qualitative component was analyzed to deduce patterns and themes on the patient and family experiences. Descriptive statistics were used to quantify various events along the TB care pathway including various delays (patient, diagnosis and total) and number of providers visited by patients during the diagnostic process.

RESULTS

The median patient, diagnostic and total delays were 3 (IQR: 2,5), 39 (IQR: 23, 91) and 43 days (IQR: 28.5, 98.5), respectively. Patients visited a median of 3 (IQR: 2,4) providers before accessing Xpert MTB/RIF testing. On an average, 68.4% of physicians ordered any test most of them being irrelevant for TB diagnosis. Qualitative data showed considerable suffering for children and their families before and after TB diagnosis including serious concerns of stigma, disruption in education and social life and recurrence of the disease.

CONCLUSION

Our study highlights the significant physical and social distress that the children with TB and their families undergo along the TB care pathway. It also shows diagnostic delay in excess of a month during which multiple providers were met and the patients underwent several diagnostic tests, most of them being inappropriate. Efforts to make Xpert MTB/RIF testing more accessible and part of physicians' toolkit will be of considerable value to ease the complexity of TB diagnosis in children. In addition, communication strategy needs to be developed and implemented to generate awareness among general population around pediatric TB and its management.

Understanding why at-risk population segments do not seek care for tuberculosis: a precision public health approach in South India

INTRODUCTION

Delaying care-seeking for tuberculosis (TB) symptoms is a major contributor to mortality, leading to worse outcomes and spread. To reduce delays, it is essential to identify barriers to care-seeking and target populations most at risk of delaying. Previous work identifies barriers only in people within the health system, often long after initial care-seeking.

METHODS

We conducted a community-based survey of 84 625 households in Chennai, India, to identify 1667 people with TB-indicative symptoms in 2018-2019. Cases were followed prospectively to observe care-seeking behaviour. We used a comprehensive survey to identify care-seeking drivers, then performed multivariate analyses to identify care-seeking predictors. To identify profiles of individuals most at risk to delay care-seeking, we segmented the sample using unsupervised clustering. We then estimated the per cent of the TB-diagnosed population in Chennai in each segment.

RESULTS

Delayed care-seeking characteristics include smoking, drinking, being employed, preferring different facilities than the community, believing to be at lower risk of TB and believing TB is common. Respondents who reported fever or unintended weight loss were more likely to seek care. Clustering analysis revealed seven population segments differing in care-seeking, from a retired/unemployed/disabled cluster, where 70% promptly sought care, to a cluster of employed men who problem-drink and smoke, where only 42% did so. Modelling showed 54% of TB-diagnosed people who delay care-seeking might belong to the latter segment, which is most likely to acquire TB and least likely to promptly seek care.

CONCLUSION

Interventions to increase care-seeking should move from building general awareness to addressing treatment barriers such as lack of time and low-risk perception. Care-seeking interventions should address specific beliefs through a mix of educational, risk perception-targeting and social norms-based campaigns. Employed men who problem-drink and smoke are a prime target for interventions. Reducing delays in this group could dramatically reduce TB spread.

Engaging Informal Private Health Care Providers for TB Case Detection: Experiences from RIPEND Project in India

Background

Informal (unqualified) health care providers are an important source of medical care for persons with presumptive TB (PPTB) in India. A project (titled RIPEND) was implemented to engage informal providers for the identification of PPTBs and TB patients in 4 districts of Telangana State, India, during October 2018-December 2019 project period. Engagement involved sensitizing the informal providers about TB, providing them financial incentives to identify PPTBs, and linking these PPTBs to diagnostic and treatment services provided by the Government of India's National TB Elimination Programme.

Objectives

To describe (a) the characteristics of the informal providers, along with their self-reported practices on TB diagnosis, treatment, and challenges encountered by the RIPEND project staff in engaging them in the project and (b) the outputs and outcomes of this engagement.

Methods

We used a combination of one-on-one interviews with informal providers, group interviews with RIPEND project staff, and secondary analysis of data available within the project's recording and reporting systems.

Results

A total of 555 informal providers were actively engaged under the project. The majority (87%) had a nonmedicine-related graduate degree and had been providing medical care for more than 10 years. Most (95%) were aware that a cough for 2 weeks or more is a symptom of pulmonary TB and that such patients should be referred for sputum-smear microscopy at a government health facility. Challenges in engaging the informal providers included motivating them to participate in the study, suboptimal mobile usage for referral services, and delays in providing financial incentives to them for referring PPTBs. During the project period (October 2018-December 2019), 8342 PPTBs were identified of which 1003 TB patients were detected and linked to TB treatment services.

Conclusion

This project showed that engaging informal providers is feasible and that a large number of PPTB and TB patients can be identified through this effort. The Government of India should consider engaging informal providers for the early diagnosis of TB to reduce the missing TB cases in the country.

Assessment of delayed tuberculosis diagnosis preceding diagnostic confirmation among tuberculosis patients attending Isiolo County level four hospital, Kenya

INTRODUCTION

delayed diagnosis of Mycobacterium tuberculosis infection leads to accelerated individual to individual transmission. This study evaluated this aspect of delayed diagnosis among patients visiting Isiolo level four hospital in northern Kenya.

METHODS

this was a cross-sectional cohort study conducted during January, 2018-January, 2019 with systematically sampled 172 tuberculosis (TB) patients. Epidemiological and clinical characteristics were abstracted from records to serve as independent variables. Outcome variable was delayed diagnosis dichotomised into < 21 or > 21 days and treated as a binary outcome. Pre-tested interviewer-administered questionnaires, focused group discussions, and key informant interview guides were used to collect relevant information.

RESULTS

most (n=89, 57.8%) of the TB diagnosis fell in the category of > 21 day delay. Overall, among all patients, delay in days constituted a median of 27.6, a mean of 37.3 ± 57 days (range 0-414 days). Factors associated with delayed diagnosis (happening > 21 days) included (i) use of dispensary and private health facilities, (OR=4.3, 95% CI: 1.44,13.14; P=0.009) and (OR= 4.9, 95% CI: 1.64, 14.73; P=0.004), respectively (ii) Self-employed individuals (OR=21.7, 95% CI: 2.47,190.93; P=0.006) and employed individuals (OR=9.9, 95% CI: 1.14, 85.80; P=0.038) (iii) secondary-level education (OR=0.03, 95% CI: 0.01,0.21; P=0.000) and tertiary education (OR=0.033, 95% CI: 0.01, 0.23; P=0.001).

CONCLUSION

delayed diagnosis of TB was found to be associated with health-seeking behaviour of TB patients, proxied by diagnosis facility, occupation, and education levels in our study area. Curtailment of local transmission of M. tuberculosis needs intensified health promotion and education in affected communities complemented with active case findings.

The potential impact of preventive therapy against tuberculosis in the WHO South-East Asian Region: a modelling approach

BACKGROUND

The prevention of tuberculosis (TB) is key for accelerating current, slow declines in TB burden. The 2018 World Health Organization (WHO) guidelines on eligibility for preventive therapy to treat latent TB infection (LTBI) include people living with human immunodeficiency virus (PLHIV), household contacts of TB patients including children, and those with clinical conditions including silicosis, dialysis, transplantation, etc. and other country-specific groups. We aimed to estimate the potential impact of full implementation of these guidelines in the WHO South-East Asian (SEA) Region, which bears the largest burden of TB and LTBI amongst the WHO regions.

METHODS

We developed mathematical models of TB transmission dynamics, calibrated individually to each of the 11 countries in the region. We modelled preventive therapy in the absence of other TB interventions. As an alternative comparator, reflecting ongoing developments in TB control in the region, we also simulated improvements in the treatment cascade for active TB, including private sector engagement and intensified case-finding. Relative to both scenarios, for each country in the region, we projected TB cases and deaths averted between 2020 and 2030, by full uptake of preventive therapy, defined as comprehensive coverage amongst eligible populations as per WHO guidelines, and assuming outcomes consistent with clinical trials. We also performed sensitivity analysis to illustrate impact under less-than-optimal conditions.

RESULTS

At the regional level, full uptake of preventive therapy amongst identified risk groups would reduce annual incidence rates in 2030 by 8.30% (95% CrI 6.48-10.83) relative to 2015, in the absence of any additional interventions. If implemented against a backdrop of improved TB treatment cascades, preventive therapy would achieve an incremental 6.93 percentage points (95% CrI 5.81-8.51) of reduction in annual incidence rates, compared to 2015. At the regional level, the numbers of individuals with latent TB infection that need to be treated to avert 1 TB case is 64 (95% CrI 55-74). Sensitivity analysis illustrates that results for impact are roughly proportional to 'effective coverage' (the product of actual coverage and effectiveness of the regimen).

CONCLUSIONS

Full implementation of WHO guidelines is important for ending TB in the SEA Region. Although future strategies will need to be expanded to the population level, to achieve large declines in TB incidence, the uptake of current tools can offer a valuable step in this direction.

Pre-diagnostic drop out of presumptive TB patients and its associated factors at Bugembe Health Centre IV in Jinja, Uganda

BACKGROUND

Drop out of presumptive TB individuals before making a final diagnosis poses a danger to the individual and their community. We aimed to determine the proportion of these presumptive TB drop outs and their associated factors in Bugembe Health Centre, Jinja, Uganda.

METHODS

We used data from the DHIS2, presumptive and laboratory registers of Bugembe Health Centre IV for 2017. Descriptive statistics were used to summarize the population characteristics. A modified Poisson regression model via the generalized linear model (GLM) with log link and robust standard errors was used for bivariate and multivariate analysis.We used data from the DHIS2, presumptive and laboratory registers of Bugembe Health Centre IV for 2017. Descriptive statistics were used to summarize the population characteristics. A modified Poisson regression model via the generalized linear model (GLM) with log link and robust standard errors was used for bivariate and multivariate analysis.

RESULT

Among the 216 registered presumptive TB patients who were less than 1% of patients visiting the outpatients' department, 40.7% dropped out before final diagnosis was made. Age and HIV status were significantly associated with pre-diagnostic drop out while gender and distance from the health center were not.

CONCLUSION

A high risk to individuals and the community is posed by the significant proportion of presumptive TB patients dropping out before final diagnosis. Health systems managers need to consider interventions targeting young persons, male patients, HIV positive persons.

Delays and barriers to early treatment initiation for childhood tuberculosis in India

BACKGROUND: India accounts for 27% of global childhood tuberculosis (TB) burden. Understanding barriers to early diagnosis and treatment in children may improve care and outcomes.METHODS: A cross-sectional study was performed among 89 children initiated on anti-TB treatment from a public hospital in Pune during 2016, using a structured questionnaire and hospital records. Health care providers (HCPs) were defined as medical personnel consulted about the child's TB symptoms. Time-to-treatment initiation (TTI) was defined as the number of days between onset of TB symptoms and anti-TB treatment initiation. Based on Revised National TB Control Programme recommendations, delayed TTI was defined as >28 days.RESULTS: Sixty-seven (75%) of 89 enrolled children had significant TTI delays (median 51 days, interquartile range [IQR] 27-86). Sixty-six (74%) children visited 1-8 HCPs in the private sector before approaching the public sector. The median HCP delay was 28 days (IQR 10-75). Bacille Calmette-Guérin vaccination (aOR 10.96, P = 0.04) and loss of appetite (aOR 4.44, P = 0.04) were associated with delayed TTI.CONCLUSION: The majority of the children had TTI delays due to delays by HCPs in the private sector. Strengthening HCP competency in TB symptom screening and encouraging early referrals are crucial for rapid scaling up of early treatment initiation in childhood TB.

Predicting the impact of patient and private provider behavior on diagnostic delay for pulmonary tuberculosis patients in India: A simulation modeling study

BACKGROUND

Tuberculosis (TB) incidence in India continues to be high due, in large part, to long delays experienced by patients before successful diagnosis and treatment initiation, especially in the private sector. This diagnostic delay is driven by patients' inclination to switch between different types of providers and providers' inclination to delay ordering of accurate diagnostic tests relevant to TB. Our objective is to quantify the impact of changes in these behavioral characteristics of providers and patients on diagnostic delay experienced by pulmonary TB patients.

METHODS AND FINDINGS

We developed a discrete event simulation model of patients' diagnostic pathways that captures key behavioral characteristics of providers (time to order a test) and patients (time to switch to another provider). We used an expectation-maximization algorithm to estimate the parameters underlying these behavioral characteristics, with quantitative data encoded from detailed interviews of 76 and 64 pulmonary TB patients in the 2 Indian cities of Mumbai and Patna, respectively, which were conducted between April and August 2014. We employed the estimated model to simulate different counterfactual scenarios of diagnostic pathways under altered behavioral characteristics of providers and patients to predict their potential impact on the diagnostic delay. Private healthcare providers including chemists were the first point of contact for the majority of TB patients in Mumbai (70%) and Patna (94%). In Mumbai, 45% of TB patients first approached less-than-fully-qualified providers (LTFQs), who take 28.71 days on average for diagnosis. About 61% of these patients switched to other providers without a diagnosis. Our model estimates that immediate testing for TB by LTFQs at the first visit (at the current level of diagnostic accuracy) could reduce the average diagnostic delay from 35.53 days (95% CI: 34.60, 36.46) to 18.72 days (95% CI: 18.01, 19.43). In Patna, 61% of TB patients first approached fully qualified providers (FQs), who take 9.74 days on average for diagnosis. Similarly, immediate testing by FQs at the first visit (at the current level of diagnostic accuracy) could reduce the average diagnostic delay from 23.39 days (95% CI: 22.77, 24.02) to 11.16 days (95% CI: 10.52, 11.81). Improving the diagnostic accuracy of providers per se, without reducing the time to testing, was not predicted to lead to any reduction in diagnostic delay. Our study was limited because of its restricted geographic scope, small sample size, and possible recall bias, which are typically associated with studies of patient pathways using patient interviews.

CONCLUSIONS

In this study, we found that encouraging private providers to order definitive TB diagnostic tests earlier during patient consultation may have substantial impact on reducing diagnostic delay in these urban Indian settings. These results should be combined with disease transmission models to predict the impact of changes in provider behavior on TB incidence.

Effect of public-private interface agency in Patna and Mumbai, India: Does it alter durations and delays in care seeking for drug-sensitive pulmonary tuberculosis?

Background: Public–private interface agency (PPIA) intervention models in Patna (E. India) and Mumbai (W. India) for pulmonary drug-sensitive (DS) tuberculosis (TB) patients were evaluated over 2 years after maturity to examine effect on reduction of patient pathways and retention.  The models engaged private providers, diagnostic facilities and pharmacies into an effective network providing free diagnostic tests and treatment.

Methods: A population-based retrospective study was undertaken to assess effectiveness of the PPIA model in care pathways of 64 (Patna) and 86 (Mumbai) patients through in-depth interviews conducted within 6 months of initiation treatments to identify types and facilities accessed, duration to diagnosis and treatment. Median durations based on facilities accessed were statistically analysed.  Comparisons were made with baseline values and endline pathways of patients accessing PPIA engaged/non-engaged facilities in private and public sectors.

Results: Compared to non-engaged facilities, persons accessing engaged facilities at first point-of-care had shorter pathways (Mumbai: 32 vs 43 days), (Patna: 15 vs 40 days).  Duration for first care-seeking was considerably shorter for patients accessing PPIA in Patna and for both engaged and non-engaged private facilities in Mumbai (4 days).  Whilst PPIA engaged facilities diagnosed more cases than others, the RNTCP in Mumbai provided diagnosis early.  There was good retention of patients by PPIA-engaged (1 ^st) facilities (90% post-diagnosis in Patna) but this was affected by the hub-spoke referral system in Mumbai (13%). Second diagnosis is a common feature in Mumbai.  The spoke-hub model in Mumbai contributed considerably to treatment delay; PPIA-engaged providers were better at retaining patients post treatment initiation 11/25 (44%).

Conclusion: PPIA-engaged facilities, accessed at onset, result in marked reduction in pathway durations.  Such initiatives should engage a critical mass of competent providers, proximal investigation facilities with enhanced disease awareness and literacy efforts amongst communities.  Patient movement should be minimized for early treatment and retention.

New Machine, Old Cough: Technology and Tuberculosis in Patna

In 2013, a new technology, GeneXpert, was introduced in India, which, in addition to testing for TB, could also diagnose whether the detected strain was drug resistant. By detecting the bacterium more effectively than other available tests and simultaneously testing for resistance, GeneXpert promised to reduce the delay in diagnosis and hence ineffective treatments. The new test was introduced to multiple cities via a coalition that included global health funding bodies, the government of India, the World Health Organization, and non-governmental organizations. Despite the concerted effort of the coalition, among formal providers (those trained in biomedicine) in the private sector, the new technology was not adopted as quickly as had been hoped. Examining formal providers' initial responses to the technology's introduction in the city of Patna reveals how the adoption of new technology can be influenced by the particularities of the local medical market such as the availability of diagnostic tests, presence of informal providers, and reputation of formal providers. While protocols and operations might seem standardized across implementation plans, the work that is required to ensure success must take into account the particular role that the market plays from site to site.

Understanding pretreatment loss to follow-up of tuberculosis patients: an explanatory qualitative study in Chennai, India

Introduction

Pretreatment loss to follow-up (PTLFU)-dropout of patients after diagnosis but before treatment registration-is a major gap in tuberculosis (TB) care in India and globally. Patient and healthcare worker (HCW) perspectives are critical for developing interventions to reduce PTLFU.

Methods

We tracked smear-positive TB patients diagnosed via sputum microscopy from 22 diagnostic centres in Chennai, one of India's largest cities. Patients who did not start therapy within 14 days, or who died or were lost to follow-up before official treatment registration, were classified as PTLFU cases. We conducted qualitative interviews with trackable patients, or family members of patients who had died. We conducted focus group discussions (FGDs) with HCWs involved in TB care. Interview and FGD transcripts were coded and analysed with Dedoose software to identify key themes. We created categories into which themes clustered and identified relationships among thematic categories to develop an explanatory model for PTLFU.

Results

We conducted six FGDs comprising 53 HCWs and 33 individual patient or family member interviews. Themes clustered into five categories. Examining relationships among categories revealed two pathways leading to PTLFU as part of an explanatory model. In the first pathway, administrative and organisational health system barriers-including the complexity of navigating the system, healthcare worker absenteeism and infrastructure failures-resulted in patients feeling frustration or resignation, leading to disengagement from care. In turn, HCWs faced work constraints that contributed to many of these health system barriers for patients. In the second pathway, negative HCW attitudes and behaviours contributed to patients distrusting the health system, resulting in refusal of care.

Conclusion

Health system barriers contribute to PTLFU directly and by amplifying patient-related challenges to engaging in care. Interventions should focus on removing administrative hurdles patients face in the health system, improving quality of the HCW-patient interaction and alleviating constraints preventing HCWs from providing patient-centred care.

Tapping private health sector for public health program? Findings of a novel intervention to tackle TB in Mumbai, India

BACKGROUND

India carries one-fourth of the global tuberculosis (TB) burden. Hence the country has drafted the ambitious National Strategic Plan to eliminate tuberculosis by 2025. To realise this goal, India's Revised National Tuberculosis Control Programme (RNTCP) and partners piloted a novel strategy to engage private-providers for tuberculosis care via a "Private-provider Interface Agency" (PPIA) in Mumbai and other locations.

INTERVENTION

The program mapped and engaged private-providers, chemists, and laboratories; facilitated TB notification via call centers and field staff; provided free tuberculosis diagnostic tests and anti-TB drugs using novel electronic vouchers; monitored quality of care; and supported patients to ensure anti-TB treatment adherence and completion. This report summarises the descriptive analysis of PPIA implementation data piloted in Mumbai from 2014 to 2017.

FINDINGS

The program mapped 8789 private doctors, 3438 chemists, and 985 laboratories. Of these, 3836 (44%) doctors, 285 (29%) laboratories, and 353 (10%) chemists were prioritized and engaged in the program. Over three and a half years, the program recorded 60,366 privately-notified tuberculosis patients, of which, 24,146 (40%) were microbiologically-confirmed, 5203 (9%) were rifampicin-resistant, and 4401 (7%) were paediatric TB patients. Mumbai's annual total TB case notification rate increased from a pre-program baseline of 272 per 100,000/year in 2013 to 416 per 100,000/year in 2017. Overall, 42,300 (78%) patients completed the TB treatment, and 4979 (9%) could not be evaluated.

INTERPRETATION

The PPIA program in Mumbai demonstrated that private-providers can be effectively engaged for TB control in urban India. This program has influenced national policy and has been adapted and funded for a country-wide scale up. The model may also be considered in conditions where private-provider engagement is needed to improve access and quality of care for any area of public health.

Partnership in tuberculosis control through involvement of pharmacists in Delhi: An exploratory operational research study

BACKGROUND:

There are over 12,000 chemists registered in the capital city, Delhi to support patient health needs. A study was conducted to improve the tuberculosis (TB) notification rates as conceptualized by the Revised National Tuberculosis Control Program (RNTCP). As part of the end TB mission, the feasibility of capturing data of TB patients coming to buy anti-TB drugs at the licensee level (chemists and drug shop owners) in Central Delhi area was assessed.

MATERIALS AND METHODS:

The prospective study was conducted from July 2017 to March 2018. TB notification through a paper-based system and self-notification through online mode were the operational modality used for engagement with chemists. A team of paramedical workers was deployed for data collection from those pharmacists who chose to notify through the paper mode. Self-notification through online mode was through the RNTCP's NIKSHAY web-based reporting platform.

RESULTS:

From the 330 chemists sensitized, 871 TB notifications were received during the study. Younger age groups comprised a majority of these cases with 198 (37.5%) from 21 to 30 years and 122 (23.1%) from 11 to 20 years. By the end of six visits, 28 (46%) of the 61 pharmacies that were eventually successfully sensitized had started returning the Folio cards with filled patient details. A total of 581 (66.6%) prescriptions received by the pharmacists were from government hospitals. The annual TB case notification in Central Delhi showed a significant increase from 271 TB patients/100,000 population to 871 TB patients/100,000 population during the study period when compared with expected trends in the past year (P < 0.05).

CONCLUSION:

Self-notification of TB engenders successful TB notifications from chemists. This progenitor approach to TB notification in the capital emphasizes the need to categorize pharmacists as an independent private care provider for improving TB notification across high-burden settings.

User-experience and patient satisfaction with quality of tuberculosis care in India: A mixed-methods literature review

BACKGROUND

Tuberculosis affected 2.7 million people in India in 2017. The Revised National TB Control Programme has achieved milestones in coverage, however quality of TB care remains highly variable and often poor, with significant gaps in provider knowledge, practices, and patients consistently lost to follow-up. These quality gaps are largely informed by studies on provider practices or objective chart abstractions and case data. Per the knowledge of the author, no review has been conducted on first-hand patient perspectives on the quality of TB care they receive. This mixed-methods literature review aims to synthesize evidence on user-experience and patient satisfaction with TB care in India and inform areas for service quality improvement.

METHODS

Five medical databases, including PubMed, EMBASE, Global Health (Ovid), Web of Science, and CINAHL were searched for empirical studies on patient perspectives on TB health services published between January 1st, 2000 to December 31st, 2017. Studies in English with adult patients with any form of TB in the public or private health system were included. Studies prior to entering the health system, on distance to health facilities and cost were excluded. Seven Indian journals were hand searched and a grey literature search was conducted in GoogleScholar. Studies were assessed for methodological quality and thematic analysis was conducted by categorizing data using NVivo 12.

RESULTS

A total of 498 studies were screened, of which 23 met the inclusion criteria. 16 supplementary studies were identified from Indian journals and grey literature. Of the 39 total studies included most were quantitative (29; 74%), based in South India (17; 44%) and focused on drug-sensitive TB patients (19; 49%) within the public health system (25; 64%). Data collection methods were highly heterogenous which limited synthesis and comparisons across population demographics, health sectors, or regions. Overall quantitative patient satisfaction measured in seven studies was high. Two major themes identified were provider-related factors (n = 26 studies) and convenience (n = 25), and six minor themes were supplies and equipment availability (n = 12), confidence (n = 10), information and communication (n = 10), waiting time (n = 8), stigma (n = 4), and confidentiality (n = 4). Each reported positive and negative user-experiences. Most significantly, DOTS did not fit the daily needs and obligations of many patients, particularly due to conflicts with employment and frequency of visits; while positive provider support, information, and flexibility helped patients adhere to treatment.

CONCLUSION

Although quantitative patient satisfaction was found to be high, data were not collected using robust, validated tools. Qualitative and quantitative user-experiences in each theme were variable, making them both barriers and facilitators of good quality TB care. Poor user-experiences were often responsible for patients interrupting treatment or dropping out of TB care. Patient-centeredness, or user-friendliness of TB care can be improved by introducing individualized or flexible DOTS that is responsive to user circumstances and needs. User-experience data should be systematically collected using a standardized, national tool for identification of specific bottlenecks and successes in quality of TB care from the patients' perspective.

Initiative for Promoting Affordable and Quality Tuberculosis Tests (IPAQT): a market-shaping intervention in India

A majority of patients with tuberculosis (TB) in India are diagnosed and treated in the private sector. Yet, most private providers do not use most recent WHO-endorsed microbiological tests such as liquid cultures, line probe assays and Xpert MTB/RIF due to a combination of factors such as lack of awareness, misaligned incentives and high prices that are unaffordable for patients. We designed a market-based approach to transform a high-price, low-volume market equilibrium into a low-price, high-volume equilibrium to improve the uptake of these tests. Toward this end, a non-profit consortium of private laboratories, called Initiative for Promoting Affordable and Quality Tuberculosis Tests (IPAQT) was formed in India in March 2013. It negotiated lower pricing on equipment and reagents with manufacturers, closer to that offered to the public sector. In return, IPAQT assured that this discount was passed on to patients, who typically paid for these tests out of their pockets, through an informally agreed on retail ceiling price. IPAQT also invested in demand generation activities that complemented the supply-side effort. IPAQT membership grew from 56 laboratories in 2013 to 211 in 2018. During this period, the initiative resulted in a 10-fold increase in the uptake of Xpert and a 30%-50% reduction in price. This initiative is planned to be expanded to other South Asian countries with similar TB epidemic and private market structure and dynamics. However, long-term sustainability of the initiative would require developing more cost-effective marketing activities and integration with broader private sector engagement agenda of the national TB programme.

In the eye of the multiple beholders: Qualitative research perspectives on studying and encouraging quality of TB care in India

This paper outlines insights qualitative research brings to the study of quality of care. It advocates understanding care as sequential, interpersonal action aimed at improving health and documenting the networks in which care occurs. It assesses the strengths and weakness of contemporary quantitative and qualitative approaches to examining quality of care for tuberculosis (TB) before outlining three qualitative research programs aimed at understanding quality of TB in India. Three case studies focus on the diagnosis level in the cascade of TB care and use qualitative research to examine the clinical use of pharmaceuticals as diagnostics, the development of diagnostic tests, and the role of care providers in the utilization of diagnostic services. They show that 1) care must be understood as part of relationships over time, 2) the presence or absence of technologies does not always imply their expected use in care, 3) physicians' provision of care is often inflected by their perceptions of patient desires, and 4) effective care is not always perfectly aligned with global health priorities. Qualitative methods with a networked perspective on care provide novel findings that can and have been used when developing quality of care improvement interventions for TB.

Self-reported tuberculosis in India: evidence from NFHS-4

This paper reports self-reported levels and socioeconomic patterns in the distribution of tuberculosis (TB) cases in India, based on information collected under the National Family Health Survey-Round 4 (NFHS-4, 2014-2015). Based on a nationally representative sample of over 600 000 households comprising of about 2.9 million individuals, we estimate a self-reported point prevalence of 304 TB cases per 100 000 population, with a higher burden evident among households with poorer wealth status and among individuals with low educational levels. About 55% of the reported TB cases sought treatment from public services, with higher public service use observed in West Bengal, Kerala and Tamil Nadu. However, more than a third of the patients from poorest groups sought treatment from private sources. Results indicate a significant proportion of the general population, including those with completed school-level education continue to have incomplete knowledge on the routes of the spread of TB infection. Social stigma, such as reluctance to disclose about a family member being infected with the disease to others, also remains high. Imminent need for appropriate policy mechanisms for involving the private sector and raising consciousness through suitable advocacy measures is re-emphasised.

Can community pharmacists improve tuberculosis case finding? A mixed methods intervention study in India

Introduction

India has the world’s highest burden of tuberculosis (TB). Private retail pharmacies are the preferred provider for 40% of patients with TB symptoms and up to 25% of diagnosed patients. Engaging pharmacies in TB screening services could improve case detection.

Methods

A novel TB screening and referral intervention was piloted over 18 months, under the pragmatic staggered recruitment of 105 pharmacies in Patna, India. The intervention was integrated into an ongoing public–private mix (PPM) programme, with five added components: pharmacy training in TB screening, referral of patients with TB symptoms for a chest radiograph (CXR) followed by a doctor consultation, incentives for referral completion and TB diagnosis, short message service (SMS) reminders and field support. The intervention was evaluated using mixed methods.

Results

81% of pharmacies actively participated in the intervention. Over 132.49 pharmacy person-years of observation in the intervention group, 1674 referrals were made and 255 cases of TB were diagnosed. The rate of registration of symptomatic patients was 62 times higher in the intervention group compared with the control group (95% CI: 54 to 72). TB diagnosis was 25 times higher (95% CI: 20 to 32). Microbiological testing and test confirmation were also significantly higher among patients diagnosed in the intervention group (p<0.001). Perceived professional credibility, patient trust, symptom severity and providing access to a free screening test were seen to improve pharmacists’ engagement in the intervention. Workload, patient demand for over-the-counter medicines, doctor consultation fees and programme documentation impeded engagement. An additional 240 cases of TB were attributed to the intervention, and the approximate cost incurred per case detected due to the intervention was US$100.

Conclusions

It is feasible and impactful to engage pharmacies in TB screening and referral activities, especially if working within existing public-private mix (PPM) programmes, appealing to pharmacies’ business mindset and among pharmacies with strong community ties.

Pre-treatment loss to follow-up and treatment delay among bacteriologically-confirmed tuberculosis patients diagnosed in Mandalay Region, Myanmar

Background

Pre-treatment loss to follow-up (PTLFU) among tuberculosis (TB) patients is a global public health problem, because such patients are highly infectious and experience high mortality. There is no published evidence on this issue from Myanmar.

Objective

To determine PTLFU and treatment delays (> 7 days duration between the date of diagnosis and starting anti-TB treatment) and their associated demographic, clinical, and health system-related factors among bacteriologically confirmed (sputum smear-positive and/or Xpert-positive) TB patients diagnosed in public health facilities of the Mandalay Region between January and June 2017.

Method

This was a cohort study involving secondary analysis of routine programme data. Every bacteriologically confirmed TB patient in the laboratory register was tracked for at least 3 months in the treatment register. Patients neither found in the treatment register nor referred out for treatment were considered PTLFU.

Results

Of the 1365 bacteriologically confirmed patients diagnosed, 1051 (77%) started on anti-TB treatment, 200 (15.6%) were referred for treatment to health facilities outside the study area, and 114 (8.4%, 95% CI 7.0%–9.9%) did not initiate anti-TB treatment (PTLFU). PTLFU was significantly higher in those with TB/HIV co-infected (18%), sputum smear-negative but Xpert MTB-positive patients (31%), and patients diagnosed at a moderate- or high-volume facility (> 50 patients tested form TB during the study period) (~ 10%). Of the 940 patients with dates recorded, 46 (5%) had a treatment delay of more than 7 days. Patients aged 45–64 years had higher risk of treatment delay compared to those aged 15–44 years. About 97% of records did not have a phone number recorded.

Conclusion

PTLFU and treatment delay were relatively low in the Mandalay Region. While this is reassuring, urgent steps must be taken to address those that are lost, which includes improving documentation of phone numbers to improve ‘trackability’, instituting proactive measures to trace patients lost in the care pathway, and introducing an indicator in the national tuberculosis programme (NTP) monthly report to monitor and review PTLFU. Patient subgroups with higher PTLFU should receive priority attention.

Modelling the impact of effective private provider engagement on tuberculosis control in urban India

In India, the country with the world’s largest burden of tuberculosis (TB), most patients first seek care in the private healthcare sector, which is fragmented and unregulated. Ongoing initiatives are demonstrating effective approaches for engaging with this sector, and form a central part of India’s recent National Strategic Plan: here we aimed to address their potential impact on TB transmission in urban settings, when taken to scale. We developed a mathematical model of TB transmission dynamics, calibrated to urban populations in Mumbai and Patna, two major cities in India where pilot interventions are currently ongoing. We found that, when taken to sufficient scale to capture 75% of patient-provider interactions, the intervention could reduce incidence by upto 21.3% (95% Bayesian credible interval (CrI) 13.0–32.5%) and 15.8% (95% CrI 7.8–28.2%) in Mumbai and Patna respectively, between 2018 and 2025. There is a stronger impact on TB mortality, with a reduction of up to 38.1% (95% CrI 20.0–55.1%) in the example of Mumbai. The incidence impact of this intervention alone may be limited by the amount of transmission that has already occurred by the time a patient first presents for care: model estimates suggest an initial patient delay of 4–5 months before first seeking care, followed by a diagnostic delay of 1–2 months before ultimately initiating TB treatment. Our results suggest that the transmission impact of such interventions could be maximised by additional measures to encourage early uptake of TB services.

Patient Health Seeking and Diagnostic Delay in Extrapulmonary Tuberculosis: A Hospital Based Study from Central India

Objective

We aimed to investigate the awareness, health care seeking behavior, and diagnostic delay in extrapulmonary tuberculosis (EPTB) in a resource-constrained setting from Central India.

Setting and Method

Questionnaire based interview of 1220 EPTB patients ≥14 years of age was conducted between July 2004 and August 2012 at Ujjain charitable Hospital, Ujjain, India.

Results

Only 15% of patients had ever heard about EPTB and 2-4% knew about its prevention or treatment. Only 12% patients first sought medical advice while 49% patients practiced self-medication, 28% consulted traditional healers and 11% drug store/pharmacy. The median patient delay was 8 weeks (4.6-21.4 weeks). Majority (78%) of patients visited ≥3 health centers. Thirty-eight percent patients first visited any government health facility. Majority (97%) who first visited district and primary public health center were referred to private sector for investigations and 82% patients changed the consultation to private doctor after initial visit to public hospital. The median health system delay was 7 weeks (0.6-16.4 weeks).

Conclusion

Patients had very poor awareness of EPTB. Patients were referred from public to private sector in search of diagnostic facilities. Improvement of public awareness about EPTB and better public-private partnership may contribute towards reduction in diagnostic delay.

Such a long journey: What health seeking pathways of patients with drug resistant tuberculosis in Mumbai tell us

INTRODUCTION

The Indian Tuberculosis (TB) Programme currently faces the dual challenges of tackling increasing numbers of drug resistant (DR) TB cases and regulating practices of a pluralistic private sector catering to TB patients. A study of health seeking behaviour of DR-TB patients in such a situation, offers an opportunity to understand the problems patients face while interacting with health systems.

METHODOLOGY

Forty-six DR-TB patients drawn from 15 high TB burden wards in Mumbai were interviewed using an open ended interview tool. Interviews were audio recorded and transcribed. Pathway schematics developed from analysis of patient records, were linked to transcripts. Open coding was used to analyse these units and themes were derived after collating the codes.

RESULTS AND DISCUSSION

The paper presents themes interwoven with narratives in the discussions. These include awareness-action gap among patients, role of neighbourhood providers, responsiveness of health systems, the not-such a 'merry go round' that patients go/are made to go on while seeking care, costs of diagnostics and treatment, and how DR-TB is viewed as the 'big TB'.

CONCLUSION

The recommendations are based on a preventative ethos which is sustainable, compared to interventions with top-down approaches, which get piloted, but fail to sustain impact when scaled up.

Determinants of patient and health care services delays for tuberculosis diagnosis in Italy: a cross-sectional observational study

Background

Prompt diagnosis of active tuberculosis (TB) has paramount importance to reduce TB morbidity and mortality and to prevent the spread of Mycobacterium tuberculosis. Few studies so far have assessed the diagnostic delay of TB and its risk factors in low-incidence countries.

Methods

We present a cross-sectional multicentre observational study enrolling all consecutive patients diagnosed with TB in seven referral centres in Italy. Information on demographic and clinical characteristics, health-seeking trajectories and patients’ knowledge and awareness of TB were collected. Diagnostic delay was assessed as patient-related (time between symptoms onset and presentation to care) and healthcare-related (time between presentation to care and TB diagnosis). Factors associated with patient-related and healthcare-related delays in the highest tertile were explored using uni- and multivariate logistic regression analyses.

Results

We enrolled 137 patients, between June 2011 and May 2012. The median diagnostic delay was 66 days (Interquartile Range [IQR] 31–146). Patient-related and healthcare-related delay were 14.5 days (IQR 0–54) and 31 days (IQR: 7.25–85), respectively. Using multivariable analysis, patients living in Italy for < 5 years were more likely to have longer patient-related delay (> 3 weeks) than those living in Italy for > 5 years (Odds Ratio [OR] 3.47; 95% Confidence Interval [CI] 1.09–11.01). The most common self-reported reasons to delay presentation to care were the mild nature of symptoms (82%) and a good self-perceived health (76%). About a quarter (26%) of patients had wrong beliefs and little knowledge of TB, although this was not associated with longer diagnostic delay. Regarding healthcare-related delay, multivariate analysis showed that extra-pulmonary TB (OR 4.3; 95% CI 1.4–13.8) and first contact with general practitioner (OR 5.1; 95% CI 1.8–14.5) were both independently associated with higher risk of healthcare-related delay > 10 weeks.

Conclusions

In this study, TB was diagnosed with a remarkable delay, mainly attributable to the healthcare services. Delay was higher in patients with extra-pulmonary disease and in those first assessed by general practitioners. We suggest the need to improve knowledge and raise awareness about TB not only in the general population but also among medical providers. Furthermore, specific programs to improve access to care should be designed for recent immigrants, at significantly high risk of patient-related delay.

Trial registration

The study protocol was registered under the US National Institute of Health ClinicalTrials.gov register, reference number: NCT01390987. Study start date: June 2011.

Variations in the quality of tuberculosis care in urban India: A cross-sectional, standardized patient study in two cities

BACKGROUND

India has the highest burden of tuberculosis (TB). Although most patients with TB in India seek care from the private sector, there is limited evidence on quality of TB care or its correlates. Following our validation study on the standardized patient (SP) method for TB, we utilized SPs to examine quality of adult TB care among health providers with different qualifications in 2 Indian cities.

METHODS AND FINDINGS

During 2014-2017, pilot programs engaged the private health sector to improve TB management in Mumbai and Patna. Nested within these projects, to obtain representative, baseline measures of quality of TB care at the city level, we recruited 24 adults to be SPs. They were trained to portray 4 TB "case scenarios" representing various stages of disease and diagnostic progression. Between November 2014 and August 2015, the SPs visited representatively sampled private providers stratified by qualification: (1) allopathic providers with Bachelor of Medicine, Bachelor of Surgery (MBBS) degrees or higher and (2) non-MBBS providers with alternative medicine, minimal, or no qualifications. Our main outcome was case-specific correct management benchmarked against the Standards for TB Care in India (STCI). Using ANOVA, we assessed variation in correct management and quality outcomes across (a) cities, (b) qualifications, and (c) case scenarios. Additionally, 2 micro-experiments identified sources of variation: first, quality in the presence of diagnostic test results certainty and second, provider consistency for different patients presenting the same case. A total of 2,652 SP-provider interactions across 1,203 health facilities were analyzed. Based on our sampling strategy and after removing 50 micro-experiment interactions, 2,602 interactions were weighted for city-representative interpretation. After weighting, the 473 Patna providers receiving SPs represent 3,179 eligible providers in Patna; in Mumbai, the 730 providers represent 7,115 eligible providers. Correct management was observed in 959 out of 2,602 interactions (37%; 35% weighted; 95% CI 32%-37%), primarily from referrals and ordering chest X-rays (CXRs). Unnecessary medicines were given to nearly all SPs, and antibiotic use was common. Anti-TB drugs were prescribed in 118 interactions (4.5%; 5% weighted), of which 45 were given in the case in which such treatment is considered correct management. MBBS and more qualified providers had higher odds of correctly managing cases than non-MBBS providers (odds ratio [OR] 2.80; 95% CI 2.05-3.82; p < 0.0001). Mumbai non-MBBS providers had higher odds of correct management than non-MBBS in Patna (OR 1.79; 95% CI 1.06-3.03), and MBBS providers' quality of care did not vary between cities (OR 1.15; 95% CI 0.79-1.68; p = 0.4642). In the micro-experiments, improving diagnostic certainty had a positive effect on correct management but not across all quality dimensions. Also, providers delivered idiosyncratically consistent care, repeating all observed actions, including mistakes, approximately 75% of the time. The SP method has limitations: it cannot account for patient mix or care-management practices reflecting more than one patient-provider interaction.

CONCLUSIONS

Quality of TB care is suboptimal and variable in urban India's private health sector. Addressing this is critical for India's plans to end TB by 2025. For the first time, we have rich measures on representative levels of care quality from 2 cities, which can inform private-sector TB interventions and quality-improvement efforts.

Tuberculosis patients not covered by treatment in public health services: findings from India's National Family Health Survey 2015-16

OBJECTIVE

Half of the TB patients in India seek care from private providers resulting in incomplete notification, varied quality of care and out-of-pocket expenditure. The objective of this study was to describe the characteristics of TB patients who remain outside the coverage of treatment in public health services.

METHODS

Cross-sectional data from National Family Health Survey-4 (2015-16) were analysed using logistic regression analysis. TB treatment was the dependent variable. Sociodemographic factors and place where households generally seek treatment were independent variables.

RESULTS

Prevalence of self-reported TB was 308.17/100 000 population (95% CI: 309.44-310.55/100 000 population) and 38.8% (95% CI: 36.5-41.1%) of TB patients were outside care of public health services - 3.3% did not seek treatment and 35.3% accessed treatment from private sector. Factors associated with not seeking treatment were age <10 years [OR = 3.43; 95% CI (1.52-7.77); P = 0.00]; no/preschool education [OR = 1.82; 95% CI (1.10-3.34); P = 0.02]; poorest wealth index [OR = 1.86; 95% CI (1.01-3.34); P = 0.04] and household's general rejection of the public sector when seeking health care [OR = 1.69; 95% CI (1.69-2.26); P = 0.00]. Factors associated with seeking treatment from private providers were female sex [OR = 1.29; 95% CI (1.11-1.50); P = 0.001], younger age of the patient [OR = 2.39; 95% CI (1.62-3.53); P = 0.00], higher education [OR = 1.82; 95% CI (1.11-2.98); P = 0.02] and household's general rejection of the public sector when seeking health care [OR = 4.56; 95% CI (3.95-5.27); P = 0.00]. Patients from households reporting 'poor quality of care' as the reason for not generally preferring public health services were more likely (OR = 1.48, 95% CI = 1.19-1.65; P = 00) to access private treatment.

CONCLUSION

The study provides insights for efforts to involve the private health sector for accurate surveillance and patient groups requiring targeted interventions for linking them to the national programme.

Pathway to care for drug resistant tuberculosis cases identified during a retrospective study conducted in high TB burden wards in Mumbai

Background: Mumbai is witnessing a rising incidence of all forms of drug resistant tuberculosis (DR-TB).

Methods: A population-based, retrospective study was conducted between April and July 2014, in 15 high TB burden wards in Mumbai, to capture the patient pathways to TB care. A total of 23 DR-TB patients were identified and their pathways to access DR-TB care were recorded using semi-structured interviews.

Results: The total DR-TB pathway time of new patients (who did not report any past episode of TB) (180 days; IQR 123,346) was found to be more than twice that of retreatment patients (who reported a past episode of TB) (69 days; IQR 42,128).

Conclusions: The unacceptable delay for diagnosis and treatment of DR-TB in Mumbai advocates for consistent implementation of early screening of patients using rapid gene-based technologies.

Pulmonary tuberculosis in Patna, India: Durations, delays, and health care seeking behaviour among patients identified through household surveys

Background: Delays in accessing effective health care plays a pivotal role in increasing Tuberculosis (TB) transmission within the community. Patna, North India, with high levels of poverty and weak public health system, faces huge challenges for achieving effective TB control. The study aims to determine delays that occur from onset of TB symptoms until initiation of pulmonary TB (PTB) treatment among patients in Patna.

Methods: Of the 109 self-reporting TB patients identified through an active household survey, 64 PTB patients were interviewed. First care seeking, TB diagnostic and treatment initiation durations were calculated and delays defined for new and retreatment patients and minors and adults. Outliers exhibiting extreme delays were additionally identified.

Results: A cross sMean total pathway duration for TB care was 40 days, with diagnostic duration contributing to 58% of the duration. No significant differences were noted between new and retreatment patients. Minors, comprising of 30% of total PTB patients accessed care faster than adults, but showed significantly higher diagnostic duration (38 days vs. 17 days). Preference for private sector, chemists and allopaths was seen throughout the pathway.

Discussion: Patna requires a more effective harnessing of the private sector augmented with reliable diagnostic investigations and a focus on quality.

Enhancing the role of private practitioners in tuberculosis prevention and care activities in India

India accounts for the highest number of incident tuberculosis (TB) cases globally. Hence, to impact the TB incidence world over, there is an urgent need to address and accelerate TB control activities in the country. Nearly, half of the TB patients first seek TB care in private sector. However, the participation of private practitioners (PPs) has been patchy in TB prevention and care and distrust exists between public and private sector. PPs usually have varied diagnostic and treatment practices that are inadequate and amplify the risk of drug resistance. Hence, their regulation and involvement as key stakeholders are important in TB prevention and care in India if we are to achieve TB control at global level. However, there remain certain barriers and gaps, which are preventing their upscaling. The current paper aims to discuss the status of private sector involvement in TB prevention and care in India. The paper also discusses the strategies and initiatives taken by the government in this regard as evidence shows that the involvement of private sector in co-opting directly observed treatment short-course (DOTS) helps to enhance case finding and treatment outcomes; it improves the accessibility of quality TB care with greater geographic coverage. Besides public-private mix, DOTS has been found more cost-effective and reduces financial burden of patients. The paper also offers to present some more solutions both at policy and program level for upscaling the engagement of PPs in the national TB control program.
