Title: PNS63 WILLINGNESS TO PAY FOR HEALTH INSURANCE USING THE CONTINGENT VALUATION METHOD: A SYSTEMATIC REVIEW
Abstract: Health insurance is becoming one of the most popular sources for financing healthcare systems. Several methods can be used to estimate willingness to pay (WTP) for health insurance including Contingent Valuation (CV) method. Given that CV is gaining wide acceptance recently, assessing the quality of published studies using CV method is highly important. The aim of this study is to examine the evidence for this through a systematic review of studies that used a CV method to elicit WTP for health insurance and to determine the significant variables that associate with WTP. Electronic search was conducted in three clinical databases, which include: MEDLINE, EMBASE and PsycINFO (using Ovid interface) from their inception to May 2018. Primary studies that evaluated an individual's or household's WTP for health insurance was included. Studies were considered eligible if they gathered data from individuals or households at any country and estimated WTP for health insurance (social, national, public, and community health insurance) using the CV method. Preliminary results showed that thirty-six studies fulfilled our eligibility criteria. Most of the studies were from low-middle income countries. These studies were published between 1997-2017. Most of them were targeting households in rural areas. Several factors affected the WTP including age, education, income and household size. However, results need to be interpreted with caution due to limitations in performing appropriate validity and reliability testing. This research is expected to provide information on how the findings can be used to help capture more completely the value of health insurance and the implications for policy decisions
