Prevalence of tuberculosis in homes for the aged and orphanages of a district in Kerala, India.

BACKGROUND: India accounts for one fourth of the TB burden globally. One of the objectives of the National Strategic Plan is to achieve 90% notification rate of all TB cases. Screening of high risk groups is one of the important components towards achieving this objective. Inmates of homes for the aged and orphanages are at higher risk of having TB infection and disease. Hence this study was conducted with the objective of identifying the prevalence of TB among inmates of homes for the aged and orphanages. METHODS: A cross sectional study was done in homes for the aged and orphanages of Kollam district of Kerala in India. Sample size was estimated as 466. Cluster sampling using probability proportionate to size was used. There were 32 homes for the aged, from which 5 were selected. Out of 43 orphanages 8 were selected. Inmates were screened using a questionnaire. Those with any of the symptoms suggestive of TB were examined by a pulmonologist in a camp conducted at the institute. Those who needed further evaluation were brought to Government Medical College, Kollam/other nearest government health setting. All those who were detected to be having tuberculosis, were guided and given the care as per the NTEP treatment protocol. Permission was taken from the Collector of Kollam district. Informed written consent from the study subjects/legally accepted representative and assent were taken. RESULTS: 533 inmates were assessed from homes for the aged. The mean age was 56.70 (SD - 17.40). Five new TB patients were identified during the study. Of this three patients had extra-pulmonary and two were pulmonary TB. Eight patients were receiving treatment for TB at the time of study already, seven of which were pulmonary and one was extra-pulmonary. So the prevalence of TB in homes for the aged was 13/533 ie 2.43% (95%CI - 1.36 to 4.03%) or 2430/lakh. A higher percentage of inmates with tuberculosis were females, stayed in dormitory, had only primary education, had history of contact with TB and were undernourished compared to inmates without tuberculosis. We screened 478 children in orphanages of Kollam district. There were no children less than 5 years. Most of the children were in the age group of 10-15 years (62.1%). Nine children (1.9%) had history of contact with TB. One child had a previous history of TB. There was only one child who was suspected to have Tuberculosis, She was evaluated by a pediatrician and Tuberculosis was ruled out. CONCLUSION: The prevalence of TB in inmates of homes for the aged is much higher than the general population. This highlights the need for a more active case detection in such institutions, especially in the context of the country marching towards TB elimination. The absence of tuberculosis among children in orphanages is a positive indicator that the community is moving in the direction of TB elimination.

Occurrence, sources and risk assessment of polycyclic aromatic hydrocarbons in the coral reef waters of the Lakshadweep Archipelago, Arabian Sea.

The compound effects of anthropogenic disturbances on global and local scales threaten coral reef ecosystems of the Arabian Sea. The impacts of organic pollutants on the coral reefs and associated organisms have received less attention and are consequently less understood. This study examines the background levels, sources, and ecological implications of polycyclic aromatic hydrocarbons (PAHs) in the coral reef ecosystems of Lakshadweep Archipelago. Water and particulate matter were collected from four coral Islands (Kavaratti, Agatti, Bangaram and Perumal Par) of Lakshadweep Archipelago during January and December 2022 and analysed for 15 PAHs priority pollutants. The 15 PAHs congeners generally ranged from 2.77 to 250.47 ng/L in the dissolved form and 0.44 to 6469.86 ng/g in the particulate form. A comparison of available data among the coral reef ecosystems worldwide revealed relatively lower PAHs concentrations in the Lakshadweep coral ecosystems. The isomeric ratios of individual PAH congeners and principal component analysis (PCA) indicate mixed sources of PAHs in the water column derived from pyrogenic, low-temperature combustion and petrogenic. The risk quotient (RQ) values in the dissolved form indicate moderate risk to the aquatic organisms, while they indicate moderate to severe risk in the particulate form.

Hypertension in urban slums of southern India: Burden, awareness, health seeking, control and risk factor profile.

INTRODUCTION: Hypertension is the leading risk factor for global disease burden. Inequalities in health among urban poor and non-poor is a matter of concern. The current study was done to estimate the prevalence of hypertension and to describe the health seeking and risk factor profile of people with hypertension in the urban slums of Kochi, Kerala, India. METHODS: Blood pressure of 5980 adults from 20 randomly selected slums were measured by door to door survey by trained nurses as a part of baseline assessment for a cluster randomised controlled trial. RESULTS: Prevalence of hypertension was found to be 34.8% (95% CI 33.5-34.9). Among those with hypertension, 66.9% were aware of their hypertensive status, of which 75.8% were initiated on treatment for hypertension. Proportion of hypertensive in the population who had their blood pressure under control was 24.5%. Among hypertensive, 53% were obese, 25.1% had diabetes mellitus, 14% had history of hospitalisation for high blood pressure. Of them, 60.3% had a per capita salt consumption above 8 g/day and 47.5% of them reported sitting for more than 8 h on a usual day. Mean monthly out of pocket expenditure for treatment of hypertension was $9(Median $8, IQR $16). CONCLUSION: One in three adults in urban slums of Kochi had hypertension. High rates of obesity, salt intake, physical inactivity prevails among the people with hypertension. Awareness, treatment initiation and control rate of hypertension are lower in urban slums as compared to non-slum urban areas. Slums require additional attention to ensure equitable and universal access to hypertension control.

Local government stewardship for TB elimination in Kerala, India.

SETTING: The southern Indian state of Kerala has implemented 'Kerala Tuberculosis Elimination Mission' as 'People's Movement against TB' under the stewardship of local governments (LGs). The state has been certified by the Government of India for being on track to attain the UN Sustainable Development Goals related to TB elimination. OBJECTIVE: To document the role of LG stewardship in the successful implementation of the TB elimination activities in Kerala. DESIGN: 1) Key informant interviews with four state officials, 2) desk review of available documents, 3) in-depth interviews with seven LG leaders, three mid-level programme managers and three health department field staff. RESULTS: LG involvement led to the establishment of solutions based on local problems, enhanced outreach of services to the socially vulnerable individuals, improved treatment support to patients with TB, increased community ownership of TB elimination activities, reduced TB-related stigma and social determinants being addressed. Institutional mechanisms such as LG TB elimination task forces, formal guidance in planning interventions and appreciation of their performance in the form of awards were facilitators for LG involvement. CONCLUSION: LG stewardship can accelerate TB elimination. A good plan for engagement and institutional mechanisms are crucial for LG involvement.

CONTEXTE: L'État du Kérala, situé dans le sud de l'Inde, a mis en place la « Kerala Tuberculosis Elimination Mission ¼ dans le cadre du « People's Movement Against TB ¼, sous l'égide des gouvernements locaux (LG). Le gouvernement indien a certifié que le Kérala était sur la bonne voie pour atteindre les objectifs de développement durable des Nations unies en matière d'élimination de la TB. OBJECTIF: Documenter le rôle de l'intendance des LG dans la bonne mise en œuvre des activités d'élimination de la TB au Kérala. MÉTHODES: 1) Entretiens avec des informateurs clés (quatre responsables gouvernementaux), 2) analyse des documents disponibles, 3) entretiens approfondis avec sept responsables de LG, trois responsables de programme de niveau intermédiaire et trois membres du personnel de terrain du département de la santé. RÉSULTATS: L'implication des LG a permis d'établir des solutions au vu des problèmes locaux, d'améliorer l'accès aux services pour les personnes socialement vulnérables, d'améliorer le soutien au traitement des patients atteints de TB, de renforcer l'appropriation par la communauté des activités d'élimination de la TB, de réduire la stigmatisation liée à la TB et d'agir sur les déterminants sociaux. Les mécanismes institutionnels, tels que les groupes de travail pour l'élimination de la TB mis en place par les LG, les conseils officiels reçus pour planifier les interventions et l'appréciation des performances sous forme de récompenses ont facilité l'implication des LG. CONCLUSION: L'intendance des LG peut permettre d'accélérer l'élimination de la TB. Une bonne planification de l'engagement et des mécanismes institutionnels sont essentiels à l'implication des LG.

Health system resilience: Ensuring TB services during COVID-19 pandemic in Kerala, India.

COVID-19 pandemic has affected TB case detection and continuity of care globally. Kerala, the southern Indian state has experienced a reduction in TB notification during second and third quarter of 2020. Through (1) causal analysis (2) meticulous planning and establishment of systems (3) locally customised guidelines (4) better management of resources (5) integration with other programs and (6) good partnership with private sector, Kerala was able to catch up the TB notification and ensure that TB services remain intact even during the COVID-19 pandemic. Approach to catch up TB diagnosis included (1) Field based active case finding among the vulnerable individuals, (2) bilateral screening for TB and COVID-19, (3) enhancement of biosafety in laboratories, (4) strengthening of specimen collection and transportation systems, (5) targeted advocacy and communication to find out missed cases and (6) effective partnership with the private sector. Current experiences also show that TB case finding could be improved and delay in diagnosis could be averted by integrating TB case finding into the screening and testing systems established for COVID-19. The experiences of ensuring TB services during pandemic in Kerala also affirms the importance of maintaining an integrated and strong TB control component in the public health sector and vesting ownership of the TB control programme with the primary health care team. Community-based and community-led responses that take diagnosis, care, and support to the doors of those affected have much potential in delivering TB services in the subsequent years of pandemic.

Diagnostic and treatment delay among new pulmonary tuberculosis patients in Southern India: A cross-sectional study.

Background: Delay in diagnosis and treatment enhances tuberculosis (TB) transmission and mortality. Understanding causes for delay can help in TB elimination by 2025, the stated goal of India. Objectives: Estimate diagnostic and treatment delay in Ernakulam district of Kerala, identify associated factors, and determine health-seeking behavior and knowledge regarding TB among new pulmonary TB patients. Materials and Methods: Community-based cross-sectional study among the new pulmonary TB patients registered under Revised National TB Control Program. Patients interviewed in-person and data collected using pretested semi-structured questionnaire. Descriptive statistics expressed as frequency, percent, interquartile range, median, and mean. The Chi-square test was used to assess statistical significance (P < 0.05) of association. Backward conditional method logistic regression done using variables with P < 0.2 in univariate analysis and adjusting for possible confounders. Results: Two hundred and twenty-nine patients interviewed and the median patient, health-care system, and treatment delay were 25 days, 22 days, and 1 day, respectively. While the patient delay (>30 days) and treatment delay (>2 days) were seen in 47.6% and 41% of patients, respectively, health-care system delay was seen in 79.9% of the patients. Choosing pharmacy for initial treatment (adjusted odds ratio [aOR] = 5.217), unskilled occupation (aOR = 3.717), female gender (aOR = 3.467), previously not heard about TB (aOR = 3.410), and lower education level (aOR = 2.774) were the independent predictors of the patient delay. Visiting two or more doctors (aOR = 5.855) and initially visiting a doctor of undergraduate qualification (aOR = 3.650) were the independent predictors of health-care system delay. The diagnosis in private sector (aOR = 8.989), not being admitted (aOR = 3.441), and age above 60 years (aOR = 0.394) was the independent predictors of treatment delay. Conclusion: Initial treatment from pharmacy, consulting multiple physicians, and diagnosis by private sector cause significant delay in diagnosis and treatment of pulmonary TB.

STEPS - a patient centric and low-cost solution to ensure standards of TB care to patients reaching private sector in India.

BACKGROUND: More than half of the TB patients in India seek care from the private sector. Two decades of attempts by the National TB Program to improve collaboration between the public and private sectors have not worked except in a few innovative pilots. The System for TB Elimination in Private Sector (STEPS) evolved in 2019 as a solution to ensure standards of TB care to every patient reaching the private sector. We formally evaluated the STEPS to judge the success of the model in achieving its outcomes and to inform decisions about scaling up of the model to other parts of the country. METHODS: An evaluation team was constituted involving all relevant stakeholders. A logic framework for the STEPS model was developed. The evaluation focused on (i) processes - whether the activities are taking place as intended and (ii) proximal outcomes - improvements in quality of care and strengthening of TB surveillance system. We (i) visited 30 randomly selected STEPS centres for assessing infrastructure and process using a checklist, (ii) validated the patient data with management information system of National TB Elimination Program (NTEP) by telephonic interview of 57 TB patients (iii) analysed the quality of patient care indicators over 3 years from the management information system (iv) conducted in-depth interviews (IDI) with 33 beneficiaries and stakeholders to understand their satisfaction and perceived benefits of STEPS and (v) performed cost analysis for the intervention from the perspective of NTEP, private hospital and patients. RESULTS: Evaluation revealed that STEPS is an acceptable model to all stakeholders. IDIs revealed that all patients were satisfied about the services received. Data in management information system of NTEP were consistent with the hospital records and with the information provided by the patient. Quality of TB care indicators for patients diagnosed in private hospitals showed improvements over years as proportion of TB patients notified from private sector with a microbiological confirmation of diagnosis improved from 25% in 2018 to 38% in 2020 and the documented treatment success rate increased from 33% (2018 cohort) to 88% (2019 cohort). Total additional programmatic cost (deducting cost for patient entitlements) per additional patient with successful treatment outcome was estimated to be 67 USD. Total additional expense/business loss for implementing STEPS for the hospital diagnosing 100 TB patients in a year was estimated to be 573 USD while additional minimum returns for the hospital was estimated to be 1145 USD. CONCLUSION: Evaluation confirmed that STEPS is a low cost and patient-centric strategy. STEPS successfully addressed the gaps in the quality of care for patients seeking care in the private sector and ensured that services are aligned with the standards of TB care. STEPS could be scaled up to similar settings.

Prevalence of Tuberculosis Infection among Adults of Thiruvananthapuram District of Kerala as Measured by Interferon Gamma Release Assay - A Cross-Sectional Study.

Background: To achieve the goals of the end tuberculosis (TB) strategy, strategies for management of TB infection (TBI) have to be expanded. The first step to devise policies is to understand the distribution and determinants of TBI in the community. The objectives of the study were to estimate the prevalence of TBI using Interferon Gamma Release Assay (IGRA) and its determinants among the adult population of Thiruvananthapuram district, Kerala. Materials and Methods: A community-based, cross-sectional study using the stratified cluster sampling was carried out among the adults. TBI was detected using IGRA conducted on whole blood sample. Data on determinants were collected using a structured questionnaire by the face-to-face interview. The prevalence of TBI was estimated. Univariate and multivariate analysis was conducted to identify the determinants. Results: Age standardized prevalence of TBI among 396 adults was 20.5% (95% confidence interval [CI] 16.52-24.48). On adjusting for the possible confounders, increasing age (adjusted odds ratio [OR] 1.028; 95% CI 1.008-1.048; P = 0.005), history of contact with active TB disease (adjusted OR 7.61; 95% CI 4.43-13.05; P < 0.001), childhood contact (adjusted OR 8.20; 95% CI 3.14-21.41; P < 0.001), and household contact (adjusted OR 10.12; 95% CI 5.39-18.98; P < 0.001) were found to be the determinants of TBI in this population. Conclusion: The present study observed that nearly one-fifth of the adult population in the Thiruvananthapuram district has TBI. For the programmatic management, factors such as increasing age and contact history may be considered for the elimination of TBI in the state.

Together let us confront it: An outbreak investigation of hepatitis B in Pathanamthitta district, Kerala.

INTRODUCTION: Hepatitis B is a potentially life-threatening liver infection caused by the Hepatitis B virus (HBV). The established routes of transmission are from mother to infant, sexual contact, and exposure to blood or body fluids. Though HBV is preventable by vaccine and robust infection control practices, outbreaks of HBV infection do occur in India. However, the state of Kerala with its health parameters, one among the best in the country, cannot afford to have continuing outbreaks. An unusual increase in the reported cases of Hepatitis B in a rural area of Pathanamthitta district of Kerala, called for an outbreak investigation. AIMS: To describe the epidemiological features, to determine the risk factors associated with HBV transmission, and to suggest measures to prevent future transmission. METHODS: A community-based case-control study (1:2) was undertaken. A total of 162 participants (54 cases and 108 age, gender, and neighborhood matched controls) took part in the study. Focus group discussions were conducted with subject experts to develop an interview schedule assessing 40 risk factors. It was further reviewed by the University of Sydney. Data was collected by trained Junior Health Inspectors and Junior Public Health Nurses of the Primary Health Centers. Data was analyzed using SPSS v. 20. Proportions were compared by Univariate analysis, sub-group analysis, and logistic regression. Population Attributable Risk (PAR) was also calculated. RESULTS AND CONCLUSION: More than 90% of the infections were IgM anti-HBc positive, suggesting a recent infection. Interventions during hospitalization [OR: 7.98 (95% CI - 2.17--29.4)], family history of Hepatitis B [OR. 4.14 (95%CI - 1.73--9.9)], and laboratory investigations [OR: 3.99 (1.72--9.31)] were found to be significant risk factors. PAR was highest for laboratory interventions (32%). Vaccinating household contacts and strict enforcement of infection control practices could substantially reduce the burden of this fatal disease.

Implementing the Epidemic Diseases Act to combat Covid-19 in India: An ethical analysis.

Many states in India have invoked the provisions of the Epidemic Diseases Act, 1897, as a major tool in the fight against the Covid-19 pandemic. The current review attempts to discuss the ethical challenges in implementation of the Epidemic Diseases Act, 1897, to combat Covid-19 in India. Implementation of the Act in India has exposed its major limitations. It remains merely as a "policing" Act with no emphasis on coordinated and scientific responses to outbreaks and without provisions for protecting the rights of citizens. The Epidemic Diseases Act in its current form has the potential to cause more harm than good. Furthermore, the Epidemic Disease (Amendment) Bill, 2020, has not addressed any of these concerns. There is need for a rights-based, people-focused and public health-oriented law in India to deal with epidemics.

TB patient support systems in Kerala: A qualitative analysis.

INTRODUCTION: Tuberculosis (TB) is one of the leading causes of death due to infectious diseases in the world. Kerala a southern state in India aims to eliminate TB in the near future. In order to achieve its goal Kerala is providing various social support services to TB patients to ensure their smooth transition as they pass through the treatment cascade. Therefore, the objective of the current study was to qualitatively analyse the support systems provided for TB patients in Kerala and to assess the enablers and challenges faced during the provision of these services. METHODOLOGY: A qualitative study using grounded theory approach was carried out among TB survivors, current TB patients and healthcare workers from all 14 districts of Kerala along with district health officials. A total of 14 in depth interviews were conducted among healthcare workers from all the districts of Kerala. Three FGDs were conducted, out of which two were among TB survivors and another one among current TB patients. The data was collected till data saturation was reached. The audio recorded data was transcribed, translated, manually coded and emerging themes and sub themes were identified. Using data triangulation, conclusions were made. RESULTS: It was observed that different TB support services were being provided across all the 14 districts of Kerala. Each of these initiatives were found to be unique in their own way for bridging the gaps in the in the continuum of care provided for TB patients. The main domains identified were grouped as support services provided for getting diagnosis, services provided after diagnosis of TB, prevention of TB and support provided to the patients reaching private sector. Under each of these domains a wide range of TB support initiatives that facilitated early diagnosis, good adherence to treatment, minimising patient inconveniences, stigma reduction, prevention out of pocket expenditure and emotional support were identified. Majority of these supportive measures were found not to be uniform throughout. Those are locally customised initiatives, evolved at different time periods with common objective of patient support. Community ownership, proactive health care system and political commitment contributed to these patient support systems. CONCLUSION: These support services offered to TB patients were found to be very effective in paving the way towards the goal of TB elimination in Kerala.

Population Attributable Risk of Tuberculosis Vulnerabilities in Kerala, India.

BACKGROUND: A robust disaggregated understanding of the determinants of tuberculosis (TB) in each local setting is essential for effective health system and policy action to control TB. OBJECTIVES: The objective of the study was to identify population attributable risk (PAR) for TB disease based on the locally available evidences for Kerala, India. METHODS: Systematic review was done for risk factors of TB in the state. The second set of searches was done to understand the prevalence of the identified risk factors in general population in Kerala. With all available studies and reports, an expert group consensus was made to finalize state-specific prevalence of risk factors. Population attributable fractions were calculated for identified risk factors. RESULTS: PAR for TB disease in Kerala obtained was 24% for undernutrition, 15% for diabetes, 15% for tobacco use, and 1% for HIV. CONCLUSION: Kerala state's PAR for TB was comparatively lower for HIV but higher for diabetes mellitus. Similar exercises for summarizing population risk factors need to happen at all states for making plans to effectively combat TB.

Social stigma associated with TB and HIV/AIDS among Kudumbashree members: A crosssectional study.

INTRODUCTION: TB and HIV/AIDS are the two major public health problems. Stigma and discrimination has an enormous impact on the sufferers. The impact is felt at home, in workplace, and at the institutions. The objective of the current study was to measure the stigma and discrimination associated with TB and HIV/AIDS and to determine the underlying factors related to it among women self-help group members in Kochi city Kerala. METHODS: A cross-sectional study was carried out among the women self-help group members in Kochi city. A total of 135 participants were included in the study. The study tool was a pretested self-administered questionnaire which captured information regarding the sociodemographic profile and stigma towards TB and HIV/AIDS. RESULT: All the respondents were women with mean age group 47.1(SD- 10.7). Majority (60%) belonged to APL category and were Hindus (52.1%). All the members have heard about HIV/AIDS and TB. The respondents reported that they would not send their children for playing with infected people (TB-49.3%; HIV-37.1%), would stay away from infected people (TB-84.3%; HIV-67.1%), and had discomfort while approaching those are infected (TB-62.1%; HIV-59.3%). Stigma toward TB and HIV was found not to have any association with any of the socio demographic factors. Correlation was observed between stigma scores of TB and HIV/AIDS (r = 0.853; P = <0.001). CONCLUSION: Stigma toward TB and HIV still exists as a major issue even among women self-help group members in Kochi. It was observed that those who had stigma toward TB also had stigma toward HIV/AIDS. Therefore is need to create holistic awareness about these diseases among women self-help groups.

Lung Health Care pilot project trims patient pill load and antibiotic prescription in primary health care settings in Kerala, India.

INTRODUCTION: Kerala, the southern Indian state piloted Lung Health Care Project (LHCP) which is a locally adopted version of WHO recommended Practical Approach to Lung health (PAL). The current study assessed the impact of the project on the prescribing practices of doctors and consumption of antibiotics and other drugs. METHODS: This study compared performance of primary health care institutions with regard to drug prescriptions and consumptions before and after the implementation of the project. Chronic respiratory disease (CRD) patients in institutions implemented the project were interviewed in the OPD at exit and their prescriptions were documented at baseline and after six months. Focus group discussions were conducted with doctors to explore the reasons behind changes in drug consumption pattern. RESULTS: In the project implementing institutions, mean number of drugs prescribed for CRDs was 3.88 (SD 1.50) and 2.73 (SD 1.18) at baseline and after six months respectively (p < 0.001). Adjusted odds ratio for prescribing an antibiotic and injection to a CRD patient during impact assessment at institutions implementing project was 0.34 (95% CI 0.15-0.75 p 0.008) and 0.39 (95% CI 0.20-0.74 p 0.004) respectively, as compared to baseline. The factors which helped in reducing antibiotic and injection use as felt by the doctors were presence of a protocol, good quality trainings, supportive supervision and monitoring, availability of alternate drugs and good participation of staff nurses especially in-patient education. CONCLUSION: Strict adherence to diagnostic and management algorithms of Lung health care project in a primary health care setting in India helped in reducing pill burden to patients and prescription of antibiotics and injections.

Ocular adverse events in drug sensitive TB patients on daily fixed dose combination anti-TB drugs: A record review study from Kerala, India.

BACKGROUND: Government of India's Revised National TB Control Programme (RNTCP) has begun implementing daily fixed dose combination (FDC) anti-TB treatment regimen for drug sensitive TB patients in which ethambutol is given for six months. Prolonged ethambutol use is known to cause ocular adverse drug events (ADE). OBJECTIVES: To assess the magnitude of ocular ADEs in adult drug sensitive TB patients initiated on daily FDCs and to describe the demographic and clinical profile of patients with ocular ADEs. METHODS: We conducted a retrospective cohort study involving review of RNTCP records of all adult (age >14 years) drug sensitive TB patients initiated on daily FDCs between1st January 2018 and 31st July 2018 in Thiruvananthapuram district, Kerala State, India. RESULTS: 714 patients were initiated on daily FDCs during the study period. It was unknown whether all patients had undergone assessment for ocular ADEs. However, of these 714 patients, 8 patients (1.1%) were documented to have had ocular ADEs. Seven of these 8 patients had received ethambutol more than 15 mg/kg body weight and had developed ocular symptoms (decreased/blurring of vision) 3 months after TB treatment initiation. Ethambutol was stopped in all these 8 patients. In 5 patients it was recorded that ocular ADEs had resolved following stoppage of ethambutol and in the remaining it was unknown. CONCLUSION: The study confirms the occurrence of ocular ADEs among drug sensitive TB patients on daily FDCs and recommends strengthening of systems for assessing, documenting and managing ocular ADE.
