METHODS: Data from multiple sources were used to estimate diarrheal mortality and morbidity according to health service utilization. The proportion of this burden attributable to rotavirus was estimated from a community-based study and a meta-analysis we conducted of primary hospital-based studies. Rotavirus incidence was determined by multiplying acute gastroenteritis incidence with estimates of the proportion of gastroenteritis attributable to rotavirus. The economic burden of rotavirus disease was estimated from the health systems and societal perspective.
RESULTS: Annually, rotavirus results in 27 deaths, 31,000 hospitalizations, 41,000 outpatient visits and 145,000 episodes of home-treated gastroenteritis in Malaysia. We estimate an annual rotavirus incidence of 1 death per 100,000 children and 12 hospitalizations, 16 outpatient clinic visits and 57 home-treated episodes per 1000 children under-5 years. Annually, RVGE is estimated to cost US$ 34 million to the healthcare provider and US$ 50 million to society. Productivity loss contributes almost a third of costs to society. Publicly, privately and home-treated episodes consist of 52%, 27% and 21%, respectively, of the total societal costs.
CONCLUSIONS: RVGE represents a considerable health and economic burden in Malaysia. Much of the burden lies in privately or home-treated episodes and is poorly captured in previous studies. This study provides vital information for future evaluation of cost-effectiveness, which are necessary for policy-making regarding universal vaccination.
METHODS: The model used the best available data inputs, with uncertainty considered using probabilistic sensitivity analysis. We additionally assessed the impact of neonatal jaundice (NNJ) on the economic benefits of increasing exclusive breastfeeding rates.
RESULTS: During 2010-2019, five admissions for GE and three admissions for LRTI per 1000 births would have been prevented in the first year of life if the exclusive breastfeeding rate at 4 months increased from the actual levels (~15-30%) to 50%, resulting in annual healthcare cost savings of USD1.05 (95% CI 1.03-1.07) million/year. The cost saving would reach USD1.89 (95% CI 1.86-1.92) million/year if the exclusive breastfeeding rate at 4 months increase to 70%. However, if higher NNJ admissions during 7-90 days related to more exclusive breastfeeding are considered, the cost saving would reduce by 60%.
CONCLUSION: Our findings can guide policymakers in allocating budget and resources for breastfeeding promotion in Hong Kong. The prevention of unnecessary NNJ admissions would maximise the economic benefits of exclusive breastfeeding at 4 months.
