Abstract

Pneumococcal infections have a substantial burden in Turkey, particularly in the elderly (> 60 years) and at-risk adults (1859 years). VCR is low at approximately 2%. The first aim of this study was the evaluation of the burden of pneumococcal infections (pneumonia and bacteremia) from a public payer perspective in elderly and at-risk adults. The second aim was the evaluation of cost effectiveness of implementing a large PP V program in these populations. A decision tree model was employed using demographic and epidemiological inputs obtained from Turkish official sources and international literature. Vaccination was assumed to protect for 5 years with 60% and 50% effectiveness against BPP in elderly and at-risk adults respectively. Vaccination effectiveness of 21% against NBPP was assumed for both populations. Costs input were obtained from a previous study conducted between 2002 and 2008 in a public university hospital in Ankara, Turkey. Univariate sensitivity analyses and Monte-Carlo simulations were performed. The vaccination program was cost saving compared to no vaccination. Pneumococcal vaccination with 60% coverage led to a mean of 4,695 LYG in the elderly and 2,134 LYG in at-risk adults with 40% coverage. Mean incremental savings reached 45.4 million YTL in the elderly and 21.8 million YTL in at-risk adults. This analysis suggests that pneumococcal vaccination of elderly and at-risk adults is associated with a positive return on investment from a public payer perspective and supports the continued recommendation of pneumococcal vaccines, as well as their full funding in Turkey.
