Experiences, challenges and looking to the future in a clinical tuberculosis cohort in the time of COVID-19 in the Philippines

Comparing disease specific catastrophic cost estimates using longitudinal and cross-sectional designs: The example of tuberculosis

BACKGROUND

There has been an increasing interest in assessing disease-specific catastrophic costs incurred by affected households as part of economic evaluations and to inform joint social/health policies for vulnerable groups. Although the longitudinal study design is the gold standard for estimating disease-specific household costs, many assessments are implemented with a cross-sectional design for pragmatic reasons. We aimed at identifying the potential biases of a cross-sectional design for estimating household cost, using the example of tuberculosis (TB), and exploring optimal approaches for sampling and interpolating cross-sectional cost data to estimate household costs.

METHODS

Data on patient incurred costs, household income and coping strategies were collected from TB patients in Negros Occidental and Cebu in the Philippines between November 2018 and October 2020. The data collection tools were developed by adapting WHO Tuberculosis Patient Cost Surveys: A Handbook into a longitudinal study design. TB-specific catastrophic cost estimates were compared between longitudinal and simulated cross-sectional designs using different random samples from different times points in treatment (intensive and continuation phases).

RESULTS

A total of 530 adult TB patients were enrolled upon TB diagnosis in this study. Using the longitudinal design, the catastrophic cost estimate for TB-affected households was 69 % using the output approach. The catastrophic cost estimates with the simulated cross-sectional design were affected by the reduction and recovery in household income during the episode of TB care and ranged from 40 to 55 %.

CONCLUSION

Using longitudinally collected costs incurred by TB-affected households, we illustrated the potential limitations and implications of estimating household costs using a cross-sectional design. Not capturing changes in household income at multiple time points during the episode of the disease and estimating from inappropriate samples may result in biases that underestimates catastrophic cost.

The COVID-19 pandemic's effects on mental and psychosocial health in the Philippines: A scoping review

Low- and middle-income countries (LMICs) remained at elevated risk for the effects of the COVID-19 pandemic because of persistent stressors to their health systems. Simultaneously facing high infection rates, strict containment measures and natural disasters, the Philippines provides important grounds for health research in LMICs. This review examined how the COVID-19 pandemic affected mental and psychosocial health in the Philippines. This scoping review included literature in English from 2020 to mid-2022 from PubMed, PsycInfo and SCOPUS, and used the PRISMA-ScR and PCC-question model. Two independent reviewers conducted blind article screening and data extraction using COVIDENCE software, followed by consensus building, data charting and analyses. This work identified 405 publications across PubMed (N = 56), PsycInfo (N = 106) and SCOPUS (N = 243), of which 76 articles addressed the Philippines. Article types included 54 research articles, 10 opinion pieces, 4 literature reviews, 6 letters to journals, 1 study protocol and 1 other report. These findings focused primarily on health professionals (N = 23) and educators/learners (N = 22) and reported mostly on moderate-to-severe clinical outcomes such as fear, depression, anxiety or stress. Coping behaviors, like resiliency and other ways of adapting to the pandemic, including religious, spiritual and community-oriented approaches highlighted experiences with stringent infection prevention and control measures to contain COVID-19 in the Philippines. The COVID-19 pandemic brought severe challenges to mental and psychosocial health in the Philippines. The literature focused mostly on healthcare workers and educators/learners, and moderate-to-severe mental health outcomes in these groups. There is a need to expand studies to other sociodemographic groups and communities across the Philippines. Future work stands to benefit from more in-depth qualitative, mixed methods, longitudinal and representative quantitative research in LMICs following this pandemic. Literature reviews remain important to synthesize post-pandemic experiences by providing context for future studies and health practice in the Philippines and other LMICs.

Clinician perspectives of drug-resistant tuberculosis care services in the Philippines

BACKGROUND/OBJECTIVES

In the Philippines, treatment success rates for drug-resistant tuberculosis (DR-TB) remains low and little is known about the quality of DR-TB services. This study aimed to explore clinician's perspectives of DR-TB care services.

METHODS

We conducted semi-structured in-depth interviews from January-March 2018 with 11 providers selected purposively to explore the barriers associated with DR-TB care service delivery, best practices, and recommendations for enhancing patient care. Emerging themes were organized according to the socio-ecological framework.

RESULTS

Five major themes were identified: (1) nurses do not feel empowered; (2) particular patients are left behind and more vulnerable than others; (3) infection control practices, fear, and limited capacity in rural health centers; (4) financial insecurity due to program reimbursement mechanisms; and (5) local government support is limited and requires more involvement in support of DR-TB elimination activities. Best practices focused on tailored approaches that eliminated structural, economic, and motivational barriers for patients. Participants recommended financial support from local government units, nutritional assistance for patients, and refresher training for healthcare workers.

CONCLUSION

The findings provide additional understanding regarding the barriers that limit successful DR-TB care delivery and provide critical information to improve clinical practice and develop public health interventions for frontline staff including nurses in the Philippines. These strategies could ultimately reduce disparities associated with access to care and treatment adherence, if implemented.

Retrospective Cohort Study of Effects of the COVID-19 Pandemic on Tuberculosis Notifications, Vietnam, 2020

We evaluated the effects of the coronavirus disease pandemic on diagnosis of and treatment for tuberculosis (TB) in Vietnam. We obtained quarterly notifications for TB and multidrug-resistant/rifampin-resistant (MDR/RR) TB from 2015–2020 and evaluated changes in monthly TB case notifications. We used an interrupted time series to assess the change in notifications and treatment outcomes. Overall, TB case notifications were 8% lower in 2020 than in 2019; MDR/RR TB notifications were 1% lower. TB case notifications decreased by 364 (95% CI −1,236 to 508) notifications per quarter and MDR/RR TB by 1 (95% CI −129 to 132) notification per quarter. The proportion of successful TB treatment outcomes decreased by 0.1% per quarter (95% CI −1.1% to 0.8%) in 2020 compared with previous years. Our study suggests that Vietnam was able to maintain its TB response in 2020, despite the pandemic.
