- W2020102114 abstract "In Canada, public drug plans provide limited reimbursement for Alzheimer's disease (AD) medications. For most Canadians, the cost of these medications is paid ‘out-of-pocket-’. This study was conducted to assess the Canadian general public's willingness-to-pay (WTP) for unrestricted access to AD medications. Five-hundred participants (age 18 years or older) were recruited nationally and stratified by income. Data were collected via computer-assisted telephone interviews. Participants were presented with four ‘efficacy’ scenarios describing a hypothetical, new AD medication. In two scenarios, the medication was described as modifying the symptoms of cognitive decline. In the other two scenarios, the medication was described as halting disease progression. For each pair of ‘efficacy’ scenarios, the medication was assumed to have no adverse effects in one scenario and a 30% chance of adverse effects in the other scenario. For every scenario, participants were asked whether they would support unrestricted access to the medication through an annual increase in personal income taxes. Participants who responded affirmatively were asked to provide the maximum tax increase that they would support (maximum WTP). WTP was elicited using a bid range: $75, $150, or $225. Open-ended questions allowed participants to specify values outside the range. Participants were randomized to order of scenarios and bids. Differences between scenarios were assessed using Bowker's test of symmetry. Participants' median age was 51 years (interquartile range = 40 to 64 years) and 61% (n = 305) were female. Overall, 80% of participants (n = 398) supported a tax increase under at least one scenario. Maximum WTP did not differ across scenarios (median = $150, interquartile range = $75 to $225 [for all four scenarios]). After categorization (less than $75, $75, $150, $225, greater than $225), the distribution of maximum WTP did not differ by efficacy (symptom modification versus halting disease progression [p > 0.34]) or adverse effects (30% chance versus none [p > 0.54]). Most participants reported support for a tax increase. Once the decision was made to support an increase, maximum WTP was unaffected by efficacy or the potential for adverse effects." @default.
