OBJECTIVES:To explore an alternative approach to quantifying the burden of side effects at 1 year after treatment for prostate cancer among both patients and their partners.
METHODS:We analyzed data from 75 couples in the Family and Cancer Therapy Selection study. Paired patients and family members were independently asked about their willingness to pay (WTP) for a hypothetical new treatment that cures prostate cancer without side effects if they could reconsider their treatment decision by indicating the maximum amount they would be willing to pay given 11 separate "bids" ranging from $0 to $1500 per month. Descriptive and regression analyses were conducted for patients and family members controlling for sociodemographic characteristics and health status; Spearman correlations were also examined.
RESULTS:Among 75 couples analyzed, the income-adjusted mean WTP estimates per month were $400.8 (standard error [SE] $54.3) for patients and $650.2 (SE 72.2) for family members. The WTP between patients and family members was correlated (Pearson ρ 0.30; P = 0.01). After adjusting for covariates, the adjusted mean WTP per month was $588.1 (SE 65.77) for patients and $819.4 (SE 74.33) for family members. Wanting to avoid side effects at baseline predicted higher WTP for patients (P = 0.010). Experiencing sexual side effects was predictive of higher WTP for family members (P = 0.047).
CONCLUSIONS: Fairly high WTP amounts for a hypothetical treatment without side effects suggests that patients and their partners are experiencing important burdens 1 year after treatment. The higher amounts partners are willing to pay and the correlation with sexual side effects suggest that they are perceptive of significant treatment burdens.
