A community engagement project was designed and implemented to reach 10.6 million population in 13 districts of Uttarakhand state—India, to identify presumptive TB patients (PTBPs) and link to free diagnostics services, either through referral or sputum collection and transportation (SCT). The objective of this study is to determine additional yield of TB patients achieved by providing SCT services in comparison to referrals of PTBPs identified in hard-to-reach areas. This was before and after comparative study conducted between April-June 2014 (2Q2014-before) to July-September 2014 (3Q2014-after). SCT was advised for all PTBPs identified from community level interventions between July-September 2014 (3Q2014-after). In 3Q2014, additional 279 (34%) PTBPs were examined in the microscopy centre with an additional 36 (51%) new smear positive (NSP) patient diagnosed. A total of 46 NSP (128%) were contributed by SCT alone. Higher proportion (94%) of TB patients was initiated on treatment in 3Q2014 in comparison to 2Q2014 (91%). SCT as a strategy for early case detection in hard-to-reach difficult terrain yields positive results in comparison to mere referral of PTBPs.
The recent Global TB report raised concerns over the missing “million” Tuberculosis (TB) cases and this is believed to be concentrated around countries with high TB burden-including India [
Taking cognisance of the Global Technical Strategy; Government of India, developed National Strategic Plan for TB (2012-17) with an aim to reach, sensitize and engage, communities in hard-to-reach areas for TB prevention and care, thereby reduce the missing million cases [
Project Axshya implemented series of community engagement activities through a network of Non-governmental Organizations (NGOs) and community volunteers. Local community volunteers were identified and trained, who would then visit the mapped villages, interact with village members and inform them about Tuberculosis, prevention and care. All Presumptive TB Patients (PTBPs) identified during the community level activities would then be referred for diagnosis at publicly funded microscopy centers (MC). In addition sputum collection and transportation (SCT) services were also provided for needy PTBPs. Over the period, identified PTBPs were given the choice of referral or SCT services through volunteers and the additional yield of TB patients through SCT services over referrals were not known. Therefore, the objective of this study is to determine additional yield of TB patients achieved by providing SCT services in comparison to referrals of PTBPs identified in hard-to-reach areas.
The study was conducted between April-June 2015 in 13 districts of Uttarakhand state-India, with the before (2Q2014, April-June 2014) and after (3Q2014, July- September 2014) study design. Uttarakhand is located in the northern India, with sparsely disbursed population (10.6 million) and 70% of population lives in rural area, 69% of them are literate, 39% are daily wage earners and agriculture is the main economy. The state is 86% mountainous and 15,436 km of rural roads with infrequent, expensive and limited transportation services [
Project Axshya, an ACSM project was implemented through identified and trained local NGOs and CVs in the mapped villages of the districts in Uttarakhand. The community activities were monitored and supervised by district level project staff-District Coordinator (DC). The activities included, community meetings at village level (awareness among women groups, youth groups, school children, village health sanitation group etc., and identified PTBPs (if any) through these groups), and mid-media activities (creating TB awareness through wall painting, public announcements using mike speakers, street plays etc.) [
Community volunteers engaged under the NGOs were given two day training on TB basics-signs and symptoms, diagnosis, treatment, referrals and sputum collection and transportation. The main criteria for identification of PTBPs during the activities (outlined above) or during the visit to house-to-house were 1) cough ≥ 2 weeks 2) weight loss 3) loss of appetite 4) evening rise in temperature.
Those who had these symptoms were given the choice of referral or SCT services. For SCT services, CVs were trained to collect quality sputum and adhere to infection control measures while transporting the sputum. CVs were paid sum of Rs 100 (USD 1.62) for two samples collected per PTBPs identified. Payment was made when the sputum smear positivity was at 7% of the total samples collected. This cut-off was arrived using programme and project data.
Of the total 10.6 million, about 400,000 individuals were reached through the project activities during the 6 months and were included in the study for screening of PTBPs, diagnosis and treatment. In 2Q2014, the project referred identified PTBPs residing within 5 km (in hilly area) and 10 km (plain area) of nearest public health facility with microscopy centre (MC) for sputum smear examination. PTBPs who did not meet these criteria were given a choice of referral or SCT (two samples-spot and morning samples). Only 18% of those referred reached the MC. In 3Q2014, the strategy was revised to offer SCT services for all PTBPs irrespective of the distance from the MC. PTBPs denying the SCT services were referred with a referral slip. The results were collected by the CVs and communicated to PTBPs and those smear positives were initiated on treatment as per National Tuberculosis Programme (NTP) guideline [
The aggregated secondary data collected from project forms of community volunteers included variables―number of household visited, community meetings and mid-media activity conducted, PTBPs identified, total referred and SCT done for smear examination. In addition to these variables we analysed data collected by volunteers regarding reasons for referrals not reaching MC during their follow-up visits. The consolidated number of PTBPs identified, examined, total smear positive TB patients diagnosed and initiated on treatment were analysed. The comparison of proportions was done by Chi-square test. The p-value ≤ 0.05 were considered statistically significant. This study did not use individual patient information and identifiers. The Ethics Advisory Group of the International Union Against Tuberculosis and Lung Disease (The Union), Paris, France approved the study (approval no 17/16).
In 2Q2014, 30,835 households were covered through active case finding activity (ACF-known as Axshya SAMVAD), organized 641 community meetings and sensitized 138 RHCPs while in 3Q2014, 45,068 households were visited through ACF (48% increase), organized 744 community meetings (16% increase) and sensitized 135 RHCPs (2% decrease).
In 2Q2014, 200,000 individuals were reached through these activities and 1907 PTBPs were identified. Of these, 1413 (73%) were referred and 261 (18%) were examined. Of 1152 loss to referrals (LTR), reasons were obtained from 975 PTBPs. Most common reasons were; MC not accessible (19%), no adequate follow up of referrals (17%), loss of daily wages (15%) and pre-occupied with agricultural activities (12%) (
In 3Q2014, 200,000 individuals were reached, of which 2321 PTBPs were identified and 241 reached the MC. The referrals declined from 74% in 2Q2014 to 63% in 3Q2014 (p ≤ 0.001) with no significant difference in referrals reaching the MC (18%-2Q2014 vs 16%-3Q2014) (p = 0.14) (
Uttarakhand is among the highest TB burden states in India (95 new smear positives/100,000 populations) [

As a result one would need to travel to district hospitals and this would incur additional cost for transportation, stay at district and loss of day wages. For these reasons, the referrals of the identified PTBPs from these community will have higher LTRs. Higher LTRs are associated with distance from health facility (>10 km) and farming; results in delay in diagnosis and treatment [
The results of this study highlight SCT services could increase number of PTBPs examined for Tuberculosis in hard-to-reach areas. Secondly, community interventions activities like ACF need to be supported by SCT services for early identification of PTBPs and reduce LTR [
Conceptually, SCT would support early diagnosis, minimize TB infection transmission in community, reduce the number of doctor visits thereby preventing delay in diagnosis and treatment, and also contribute to additional TB cases in the hard-to-reach communities [
Few limitations to this study are, 1) findings of the study are applicable to similar hard-to-reach hilly terrains where there is difficulty in reaching the health facilities 2) routine project data reports were used and lacks information on age and gender, 3) the project focused on smear positive cases only and other TB cases, like smear negative and extra-pulmonary were not included.
The results of this study highlight the need for establishment of SCT services in hard-to-reach areas. Forty-six additional new sputum smear positive TB patients were identified by offering SCT services which could have been missed by referral alone. In the absence of these services, PTBPs would have sought care from various service providers and not notified to the system contributing to the missing cases. This strategy would benefit TB programmes, however, one needs to prioritize the areas and create a network of volunteers to offer quality SCT services in hard-to-reach locations in India and elsewhere.
