Abstract

Background Standardised integration of productivity costs into health economic evaluations is hindered by equity and distributional concerns. Our aim was to explore the distributive impact of productivity cost methodological variation, describing the consequences for diferent groups. Methods 527 prostate cancer survivors (2–5 years post-diagnosis) completed questions on work patterns since diagnosis. Productivity loss, categorised into temporary/permanent absenteeism, reduced hours and presenteeism, were costed in €2012. Valuation approaches included the human capital approach (HCA) and the friction cost approach (FCA), with wage multipliers (WM) applied in additional analyses. Both national and self-reported wages were used. Costs were compared across socio-demographic and economic characteristics using non-parametric tests. Results The estimated base case (HCA, using national wages) total productivity cost was €44,201 per prostate cancer survivor. Permanent absenteeism accounted for the largest cost (€18,537), followed by reduced work hours (€11,130), presenteeism (€8148) and temporary absenteeism (€6386). Alternative valuation estimates ranged from −90% (FCAnational wage: €4625) to +82% (HCAWMself-reported wage: €80,485) compared to the base case and were consistently higher for self-reported wages compared to national wages. Statistically signifcant diferences in productivity cost were found across four of the six survivor socio-demographic and economic characteristics by valuation approach, despite no signifcant diference in their physical unit equivalents. Conclusions Our results indicate that the distributional impact of productivity costs varies by socio-economic and demographic characteristics. We advocate that: productivity loss should be reported in physical units where possible; cost estimation should be subject to sensitivity analysis, and only where this is not feasible, that the HCA and national wages be used to value productivity loss where equity concerns are paramount.
