Health and Non-Health Benefits and Equity Impacts — Ogunbameru et al., BMC Public Health (2024)

Summary

A scoping review by Adeteju Ogunbameru and co-authors, published as an Open Access research article in BMC Public Health (2024) 24:2106, on health and non-health benefits and equity impacts of individual-level economic relief programs during epidemics and pandemics in high income settings. The abstract says the authors searched eight electronic databases from January 01, 2001, to April 3, 2023, and identified 27,263 de-duplicated records, of which 50 were eligible. It reports that the included studies were on COVID-19 and Influenza and that seven program types were identified, with cash transfer (n = 12) and vaccination or testing incentive (n = 9) most common. The abstract states that expanding paid sick leave programs had the highest number of studies reporting health-related outcomes.

  Abstract
  Background Economic relief programs are strategies designed to sustain societal welfare and population health dur-
  ing a regional or global scale infectious disease outbreak. While economic relief programmes are considered essential
  during a regional or global health crisis, there is no clear consensus in the literature about their health and non-health
  benefits and their impact on promoting equity.
  Methods We conducted a scoping review, searching eight electronic databases from January 01, 2001, to April 3,
  2023, using text words and subject headings for recent pathogens (coronavirus (COVID-19), Ebola, Influenza, Mid-
  dle East Respiratory Syndrome (MERS), severe acute respiratory syndrome (SARS), HIV, West Nile, and Zika), and eco-
  nomic relief programs; but restricted eligibility to high-income countries and selected diseases due to volume. Title
  and abstract screening were conducted by trained reviewers and Distiller AI software. Data were extracted in dupli-
  cates by two trained reviewers using a pretested form, and key findings were charted using a narrative approach.
  Results We identified 27,263 de-duplicated records, of which 50 were eligible. Included studies were on COVID-19
  and Influenza, published between 2014 and 2023. Zero eligible studies were on MERS, SARS, Zika, Ebola, or West Nile
  Virus. We identified seven program types of which cash transfer (n = 12) and vaccination or testing incentive (n = 9)
  were most common. Individual-level economic relief programs were reported to have varying degrees of impact
  on public health measures, and sometimes affected population health outcomes. Expanding paid sick leave pro-
  grams had the highest number of studies reporting health-related outcomes and positively impacted public health
  measures (isolation, vaccination uptake) and health outcomes (case counts and the utilization of healthcare services).
  Equity impact was most often reported for cash transfer programs and incentive for vaccination programs. Positive
  effects on general well-being and non-health outcomes included improved mental well-being and quality of life, food
  security, financial resilience, and job security.
  Conclusions Our findings suggest that individual-level economic relief programs can have significant impacts
  on public health measures, population health outcomes and equity. As countries prepare for future pandemics,
