Women's willingness to pay out-of-pocket for drug treatment for osteoporosis before and after the enactment of regulations providing public funding: evidence from a natural experiment in Israel.
This study examines women's willingness to pay (WTP) for drug treatment for osteoporosis before and after the enactment of regulations approving public funding for the drugs and for a hypothetical more effective but not funded drug. One hundred and nine postmenopausal women recruited sequentially from a large bone metabolism outpatient clinic in central Israel were asked by telephone interview to report their maximum WTP out-of-pocket for a drug that would reduce the risk of hip fracture by 50% in four hypothetical cases varying by the level of risk described. Additionally, after the regulations, responses were elicited also for a hypothetical more effective drug. Information regarding participants' sociodemographic and health characteristics, as well as their knowledge of osteoporosis, was also collected. Women would pay considerable sums of money (between 85% to 124% of the price of the drugs) for osteoporosis treatment and these sums increase significantly as the risk of suffering a hip fracture increases. After the enactment of the regulations, women were still willing to pay 54% to 100% of the price of the drugs out-of-pocket. Increased WTP after the regulations was associated with increased ability to pay and to lower levels of knowledge of the disease. After the enactment, participants' WTP for a more effective drug was no different from their WTP for a less effective drug. WTP measures show relative stability over time. The dissemination of information regarding policy or regulatory changes should be encouraged in order to ensure rational decision-making processes.
