Sex-based differences in TB treatment compliance: A mediating factor for sputum conversion among newly diagnosed pulmonary TB patients in Chennai, South India.

Background: Tuberculosis (TB) remains a global health concern, particularly in India, which carries a significant portion of the global burden. The role of sex as a determinant of health is increasingly recognized, impacting various aspects of TB, including treatment compliance and outcomes. This study aimed to determine the mediating role of treatment compliance in the relationship between sex and sputum conversion in newly diagnosed pulmonary TB patients in Chennai, South India. Methods: We conducted a retrospective cohort study among patients newly diagnosed for TB at ESIC Medical College & PGIMSR between April 2020 and April 2022. A causal mediation analysis was performed to identify the direct and indirect effects of sex on sputum conversion via the mediator, treatment compliance. We employed logistic regression models and the "paramed" package for the analysis, with bootstrapping technique for examining the significance of indirect and direct effects. Results: The Marginal Total Effect (MTE) suggested that females were more likely to have sputum positivity compared to males (OR: 6.77; p = 0.003). Direct effect of being female increased the odds of sputum positivity at the end of the intensive phase (OR: 3.42; p = 0.03). The indirect effect of being female via treatment compliance significantly increased the odds of sputum positivity at the end of the intensive phase (OR: 1.98; p = 0.03). Conclusion: The study provides evidence that treatment compliance significantly mediates the relationship between sex and sputum conversion in TB patients, highlighting the necessity to consider gendered dimensions of health in TB control strategies.

Budget impact and cost-utility analysis of prophylactic emicizumab versus on-demand bypassing agents for adolescent severe haemophilia A patients with inhibitors in India.

Introduction: Severe Haemophilia A patients with inhibitors are currently being treated with bypassing agents like activated prothrombin complex concentrates (aPCC) and recombinant factor VIIa. Emicizumab is a recombinant humanized monoclonal antibody, introduced to reduce the bleeding events, improve treatment adherence, and quality of life. However, cost-effectiveness and long-term sustainability of the intervention is not studied in a low middle income setting like India. Aim: The primary objective of this study was to evaluate the cost-utility of Emicizumab compared to traditional bypassing agents in the treatment of severe haemophilia A patients with inhibitors in India. Secondary objective was to analyze the budgetary impact of introducing Emicizumab for this patient population from the perspective of public health system in India. Methods: Markov model was created to compare the prophylactic emicizumab therapy against bypassing agents for a hypothetical cohort of 10-year-old adolescents in India. The time horizon was 10 years and model built based on health system perspective. Cost utility was expressed as costs per quality-adjusted life-years (QALYs) gained. All costs were expressed as 2021 US dollars. Probabilistic sensitivity analysis was performed to check the robustness of the estimates. Results: Prophylactic emicizumab was a cost saving intervention with negative Incremental Cost Utility Ratio (ICUR) against recombinant factor VIIa of -853,573 USD (INR -63,109,773), and negative ICUR of -211,675 USD (INR -15,650,403) against APCC. The estimated total budget for treating all the severe Haemophilia A patients with inhibitors in India was USD 59,042,000 (INR 4,365,329,312) for 10 years' time horizon (per patient cost of USD 295,210 [INR 21,826,646.56]). Conclusion: Prophylactic emicizumab therapy is a cost saving intervention when compared to both the bypassing agents as it is less costly and more effective for severe Haemophilia A patients with inhibitors in India.

Evaluation of National Patient Safety Implementation Framework in Selected Public Healthcare Facilities of Tamil Nadu: An Operational Research.

BACKGROUND: The Ministry of Health and Family Welfare has introduced the "National Patient Safety Implementation Framework" to ensure the patient safety at different levels of healthcare delivery system. However, there is limited effort made in evaluating the implementation status of this framework. Hence, we have performed the process evaluation of National Patient Safety Implementation Framework across the public healthcare facilities in Tamil Nadu. METHODS: This was a facility-level survey conducted by research assistants who visited 18 public health facilities across 6 districts of Tamil Nadu, India, for the purpose of documenting the presence of structural support systems and strategies to promote patient safety. We developed a tool for data collection based on the framework. It comprised a total of 100 indicators under the following domains and subdomains: structural support, systems for reporting, workforce, infection prevention and control, biomedical waste management, sterile supplies, blood safety, injection safety, surgical safety, antimicrobial safety, and COVID-19 safety. RESULTS: Only one facility (subdistrict hospital) belonged to the high-performing category with a score of 79.5 on the implementation of patient safety practices. About 11 facilities (4 medical colleges and 7 Government Hospitals) belonging to medium-performing category. The best-performing medical college had a score of 61.5 for patient safety practices. Six facilities (2 medical colleges, 4 Government Hospitals) belonged to low-performing category in terms of patient safety. The least-performing facilities (both subdistrict hospitals) had scores of 29.5 and 26 for patient safety practices, respectively. Because of COVID-19, there was a positive effect on biomedical waste management and infectious disease safety across all facilities. Most performed poor in the domain with structural systems to support quality and efficiency of healthcare and patient safety. CONCLUSIONS: The study concludes that based on the current situation of patient safety practices in public health facilities, it will be difficult to perform full-fledged implementation of patient safety framework by the year 2025.

Effectiveness of Covishield vaccine in preventing Covid-19 - A test-negative case-control study.

INTRODUCTION: This study aimed at assessing the vaccine effectiveness (VE) of Covishield, which is identical to AstraZeneca vaccine, in preventing laboratory-confirmed Covid-19. METHODS: Using test-negative case-control design, information on vaccination status of cases with Covid-19 among healthcare workers in our institution in Puducherry, India, and an equal number of controls matched for age and date of testing, was obtained. The groups were compared using multivariable conditional logistic regression to calculate odds ratios (OR). VE was calculated as 100*(1-adjusted odds ratio)%. RESULTS: Using data from 360 case-control pairs, VE of one dose and of two doses, in providing protection against Covid-19 was 49% (95% CI: 17%-68%) and 54% (27%-71%), respectively. Among cases with moderately severe disease that required oxygen therapy, VE following any number of vaccine doses was 95% (44%-100%). CONCLUSION: Covishield vaccine protected significantly against Covid-19, with a higher protection rate against severe forms of disease.

Prevalence of Depression and Anxiety during the COVID-19 Pandemic among the Residents of an Urban Slum in North India.

Objectives This study aimed to estimate the prevalence of depression and anxiety, and assess the knowledge, practice, and concerns regarding coronavirus disease 2019 (COVID-19) among the residents of an urban slum in Chandigarh, India. Materials and Methods Participants were screened using Patient Health Questionnaire-9 and Generalized Anxiety Disorder-7 scales. Results The mean (standard deviation) age of 200 enrolled participants was 33 (13) years with 83% ( n = 166) being females. The prevalence of depression and anxiety was 3.5% (95% confidence interval [CI]: 0.95-6.05) and 2.5% (95% CI: 0.34-4.66), respectively. Of total, 46% ( n = 92) knew that COVID-19 can transmit through droplets and 30.5% ( n = 61) were concerned that they might get infected with disease. Half of the participants ( n = 100) believed that there was unnecessary worry regarding COVID-19 and 78% ( n = 156) covered mouth while coughing or sneezing. Conclusion To cope with this critical situation, it is necessary to strengthen the awareness programs targeting the mental health issues of the people.
