Abstract
Health Impact Assessment (HIA) and Social Return on Investment (SROI) are beneficial public health methodologies that assess potential effects on health including social, economic and environmental factors and have synergies in their approaches. This paper explores how HIA and SROI can complement each other to capture and account for the impact and social value of an assessed intervention or policy.
A scoping review of academic and grey literature was undertaken to identify case studies published between January 1996 and April 2019 where HIA and SROI methods have been used to complement each other. Semi-structured interviews were carried out with nine international experts from a range of regulatory/legislative contexts to gain a better understanding of past experiences and expertise of both HIA and SROI. A thematic analysis was undertaken on the data collected. The review identified two published reports which outline when HIA and SROI have both been used to assess the same intervention. Interview results suggest that both methods have strengths as standalone processes i.e. HIAs are well-structured in their approach, assessing health in its broadest context and SROI can add value by monetizing social value as well as capturing social/environmental impact. Similarities of the two methods were identified i.e. a strong emphasis on stakeholder engagement and common shared principles. When questioned how the two methods could complement each other in practice, the results indicate the benefits of using HIA to explore initial impact, and as a platform on which to build SROI to monetarize social value.
HIA and SROI methodologies have cross-over. The research suggests potential benefits when used in tandem or combining the methods to assess impact and account for health and social value. Innovative work is now being carried out in Wales to understand the implications of this in practice and to understand how the results of the two methods could be used by decision-makers.
Key messages
HIA and SROI methods can be used in tandem to capture both the health impact and social value of policies and proposed interventions. HIA and SROI when used together can provide valuable information to inform decision makers around the health impact and social value of proposed policies and interventions.
