Insights
Pneumococcal diseases cause significant productivity loss in Thailand
Area of Science:
- Health Economics
- Epidemiology
- Pediatric Health
Background:
- Pneumococcal diseases caused an estimated 1.6 million deaths globally in 2008, disproportionately affecting children under 5.
- The impact extends beyond mortality, causing significant productivity losses for individuals and caregivers.
Purpose of the Study:
- To quantify the lifetime economic burden of pneumococcal diseases in Thailand's pediatric population.
- To assess the impact using productivity-adjusted life years (PALYs).
Main Methods:
- A decision analytic model simulated the disease burden in Thai children (0-5 years) over their lifetime.
- Calculations included years of life lost and PALYs, with a 3% discount rate.
- Scenario analyses evaluated the impact of pneumococcal conjugated vaccine 13 (PCV13) prevention.
Main Results:
- The study estimated a loss of 453,401 years of life and 457,598 PALYs due to pneumococcal diseases, translating to US$5586 million.
- PCV13 vaccination at birth could prevent 82,609 years of life and 93,759 PALYs, yielding US$1144 million in economic benefits.
- Pneumonia incidence, vaccine efficacy, and duration of protection were key factors influencing economic outcomes.
Conclusions:
- Pneumococcal diseases impose a substantial disease and financial burden on Thailand.
- Vaccination, particularly with PCV13, offers a significant opportunity to mitigate these preventable losses.
Background:
Pneumococcal diseases were estimated to cause 1.6 million deaths annually worldwide in 2008, with approximately half of these occurring in children aged under 5 years. The consequences and deaths adversely impact individuals' and caregivers' work productivity.
Objectives:
This study aimed to quantify the potential lifetime productivity loss due to pneumococcal diseases among the pediatric population in Thailand using productivity-adjusted life years (PALYs).
Methods:
A decision analytic model was used to estimate the burden of pneumococcal diseases among the current Thai population aged 0-5 years and followed up until aged 99 years or death. Base-case analysis compared years of life and PALYs lost to pneumococcal diseases. Scenario analyses investigated the benefits of prevention with pneumococcal conjugated vaccine 13 (PCV 13). All health outcomes were discounted at 3% per annum.
Results:
The base-case analysis estimated that 453,401 years of life and 457,598 PALYs would be lost to pneumococcal diseases, equating to a loss of US$5586 (95% CI 3338-10,302) million. Vaccination with PCV13 at birth was estimated to save 82,609 years of life and 93,759 PALYs, which equated to US$1144 (95% CI 367-2591) million in economic benefits. The incidence of pneumonia in those aged 0-4 years, vaccine efficacy, and the assumed period of protection were key determinants of the health economic outputs.
Conclusions:
The disease and financial burden of pneumococcal diseases in Thailand is significant, but a large proportion of this is potentially preventable with vaccination.
