Access to Geriatric Disability Care in India: A Roadmap for Research.

This paper presents an ontological review of the global research on access to geriatric disability care and a roadmap for future research to address the problem in India. First, the dominant research focus is on resources (human, financial, and spatial) that affect access to disability care; there is little focus on informational and technological resources. Second, functional disabilities are the dominant focus of the research, followed by cognitive, mental, and locomotor disabilities; there is little focus on speech, hearing, and visual disabilities. Third, barriers, inhibitors, and catalysts of physical access are the dominant focus, with relatively less focus on virtual access; there is very little emphasis on the drivers to access. Fourth, the primary, although not dominant, focus is on access for urban and rural populations; there is very little focus on access for underserved and indigenous populations. Future research must address these gaps systematically to improve access. This paper adds: (a) a systemic framework for the study of an important, complex, emerging problem; (b) a systematic review of the global research on the problem; and (c) a research roadmap to address the emerging problem in India.

Evaluation of Immunohistochemistry Technique for Diagnosis of Extrapulmonary Tuberculosis in Biopsy Tissue Specimen as Compared to Composite Diagnostic Criteria.

Introduction: Diagnosis of extrapulmonary tuberculosis (EPTB) has been challenging owing to its paucibacillary nature and diverse clinical manifestations. Immunohistochemistry (IHC) on biopsy specimens has presented a new perspective toward improving tuberculosis diagnosis. MPT64 is a unique antigen that has shown high sensitivity and specificity compared to other conventional techniques in its ability to diagnose tuberculosis as well as differentiate it from nontubercular mycobacteria. In this study, we aimed to analyze the utility of anti-MPT64 in the diagnosis of EPTB. Methods: In this cross-sectional study, conducted over a period of 1 year, 52 nonrepetitive samples from 52 participants with a presumptive diagnosis of EPTB were collected and processed. The specimens were subjected to Ziehl-Neelsen staining, GeneXpert, tissue culture by mycobacterium growth indicator tube, H and E staining, and IHC with anti-MPT64. The sensitivity and specificity of anti-MPT64 was computed against a composite diagnostic criterion. Results: Fifty-two consecutive participants satisfying the study criteria were recruited. The mean age of the study population was 37.35 ± 18.71 years. Lymph node specimen accounted for majority of the specimen processed (n = 20, 38.5%). The sensitivity of anti-MPT64 in the diagnosis of EPTB was 68.29%, specificity was 90.90%, positive predictive value was 96.55%, and negative predictive value was 43.47%, when composite criteria were considered standard for diagnosis. Conclusion: Immunohistochemical staining by anti-MPT64 is useful in establishing microbiological diagnosis of EPTB on biopsy specimens.

The burden of active infection and anti-SARS-CoV-2 IgG antibodies in the general population: Results from a statewide sentinel-based population survey in Karnataka, India.

OBJECTIVE: To estimate the burden of active infection and anti-SARS-CoV-2 IgG antibodies in Karnataka, India, and to assess variation across geographical regions and risk groups. METHODS: A cross-sectional survey of 16,416 people covering three risk groups was conducted between 3-16 September 2020 using the state of Karnataka's infrastructure of 290 healthcare facilities across all 30 districts. Participants were further classified into risk subgroups and sampled using stratified sampling. All participants were subjected to simultaneous detection of SARS-CoV-2 IgG using a commercial ELISA kit, SARS-CoV-2 antigen using a rapid antigen detection test (RAT) and reverse transcription-polymerase chain reaction (RT-PCR) for RNA detection. Maximum-likelihood estimation was used for joint estimation of the adjusted IgG, active and total prevalence (either IgG or active or both), while multinomial regression identified predictors. RESULTS: The overall adjusted total prevalence of COVID-19 in Karnataka was 27.7% (95% CI 26.1-29.3), IgG 16.8% (15.5-18.1) and active infection fraction 12.6% (11.5-13.8). The case-to-infection ratio was 1:40 and the infection fatality rate was 0.05%. Influenza-like symptoms or contact with a COVID-19-positive patient were good predictors of active infection. RAT kits had higher sensitivity (68%) in symptomatic people compared with 47% in asymptomatic people. CONCLUSION: This sentinel-based population survey was the first comprehensive survey in India to provide accurate estimates of the COVID-19 burden. The findings provide a reasonable approximation of the population immunity threshold levels. Using existing surveillance platforms coupled with a syndromic approach and sampling framework enabled this model to be replicable.

Quality of life (QOL) among older persons in an urban and rural area of Bangalore, South India.

INTRODUCTION: The increasing ageing population of India has unique challenges due to changing social structure, health issues and inaccessible healthcare facilities. These challenges can adversely affect the quality of life (QOL) of older persons. Hence, this study was undertaken with the objective of assessing the QOL among older persons in an urban and rural area of Bangalore. MATERIALS AND METHODS: Cross-sectional study was done among 977 older persons 60 years and above. Census enumeration blocks in urban areas and villages in rural areas were randomly selected and all older persons meeting the inclusion criteria were administered the WHOQOL-Bref questionnaire. RESULTS: Mean QOL scores (SD) in the physical, psychological, social relationship and environmental domains were 50.5 (5.5), 49.2 (5.5), 49.4 (6.5) and 49.3 (5.1) in rural areas and 57.4 (8.9), 58.6 (8.8), 64.6 (10.8) and 60.0 (9.4) in urban areas, respectively. Compared to urban, rural older persons uniformly have lower QOL irrespective of sex, education or financial dependence. CONCLUSION: Inequitable health resource distribution and inadequate social support systems must be addressed to improve the QOL of older persons, especially in rural areas. Primary care providing essential services can bridge this urban-rural divide and improve QOL of older persons.

Envisioning a learning surveillance system for tuberculosis.

Surveillance is critical for interrupting transmission of global epidemics. Research has highlighted gaps in the surveillance for tuberculosis that range from failure to collect real-time data to lack of standardization of data for informed decision-making at different levels of the health system. Our research aims to advance conceptual and methodological foundations for the development of a learning surveillance system for Tuberculosis, that involves systematic collection, analysis, interpretation, and feedback of outcome-specific data. It would concurrently involve the health care delivery system, public health laboratory, and epidemiologists. For our study, we systemically framed the cyber environment of TB surveillance as an ontology of the learning surveillance system. We validated the ontology by binary coding of dimensions and elements of the ontology with the metadata from an existing surveillance platform-GPMS TB Transportal. Results show GPMS TB Transportal collects a critical range of data for active case investigation and presumptive case screening for identifying and detecting confirmed TB cases. It is therefore targeted at assisting the Active Case Finding program. Building on the results, we demonstrate enhanced surveillance strategies for GPMS that are enumerated as pathways in the ontology. Our analysis reveals the scope for embedding learning surveillance pathways for digital applications in Direct Benefit Transfer, and Drug Resistance Treatment in National TB Elimination Programme in India. We discuss the possibilities of developing the transportal into a multi-level computer-aided decision support system for TB, using the innumerable pathways encapsulated in the ontology.

'Have we missed reporting adverse drug reactions under Revised National TB Control Programme?' - A mixed method study in Bengaluru, India.

OBJECTIVE: Prompt identification, reporting and management of ADRs during anti tuberculosis treatment can ensure better compliance and treatment outcomes. The study was conducted to identify the gaps and associated factors in reporting of ADRs under RNTCP; assess knowledge, attitude and practice of RNTCP staff regarding pharmacovigilance programme and explore the barriers in reporting of ADRs from provider's perspective. METHODS: Mixed method research with sequential explanatory design was carried out in Tuberculosis Units of RNTCP administrative district of Bangalore city during July to December 2017. Quantitative study was carried out among 222 patients on intensive phase of Category I and Category II DOTS to study the incidence, severity and causality of ADRs; and records of these patients were analysed for gaps in reporting. Knowledge, attitude and practice (KAP) regarding recording and reporting aspect of pharmacovigilance programme was assessed among RNTCP staff. As part of the qualitative study, focus group discussion was carried out among RNTCP staff to study barriers for reporting ADRs from the provider's perspective. RESULTS: Record analysis at the time of recruitment showed documentation of ADRs in only five patients. Subsequent analysis of patient records during the middle and end of the intensive phase (IP) did not show documentation of any ADRs. Simultaneously interviews with patients revealed 116 (52.2%), 72 (32.4%) and 53 (23.8%) patients reported one or more symptoms of ADRs. The commonest ADR symptom reported were fatigability and gastrointestinal symptoms followed by musculoskeletal symptoms. KAP among 25 RNTCP staff showed that 96% of them felt reporting of ADRs was necessary and 92% reported the ADRs to their seniors, however 12% were scared to report. The main reason expressed for non-reporting was 'managing ADRs is more important than reporting' (52%). Also, 32% felt the need for retraining of staff on reporting and documentation. Barriers to reporting of ADRs were both health-system related like insufficient training and inadequate guidelines provided to RNTCP staff and patient-related factors like lack of awareness and reluctance to report ADRs. CONCLUSION: Successful implementation of RNTCP and achievement of TB elimination requires provision of adequate information regarding ADRs to patients and intense follow-up and probing at each contact by programme staff to effectively manage ADRs.
