Evaluating the Impact of Research on Policy and Practice Case studies of HPD funded research in Ghana and Tanzania Sarah Hall
Why should research be evaluated? • Need for expenditure to be justified • Highlight good (and poor) practice • Provide justification for further funding
Methodology • Case study approach • Use of the Buxton input - output model
Buxton Input - Output Model • Stage 0 Research needs assessment • Interface (a) Project specification, selection and commissioning • Stage I Inputs • Stage II Processes • Stage III Primary outputs • Interface (b) Dissemination • Stage IV Secondary outputs • Stage V Applications • Stage VI Impacts or final outcomes
Case Studies in Ghana • Vitamin A supplementation trial 1989-95 (LSHTM) • Multi-centre trial of magnesium sulphate for management of eclampsia (NEU, University of Oxford). • Obstetric Audit 1998-2000 (University of Aberdeen) • Near Miss Audit Project (LSHTM) • Health Sector Reform and Malaria Control (local PIs supported by LSTM)
Case Studies in Tanzania • Field Trials of a “Dip it Yourself” kit for impregnation of bednets (LSHTM) • Comparison of house spraying and ITN for reduction of malaria incidence (LSHTM / NIMR) • School health programmes in primary schools (CICH / UKUMPTA) • Impact of deworming on among school age children (ICH / UKUMPTA) • Mwanza HIV / STD intervention trial (LSHTM / AMREF / NIMR / MoH)
Direct and indirect impacts found as a result of research • Direct health benefits to communities as a result of interventions introduced as part of the research study • Capacity building • Further development of the research agenda • The incorporation of research findings into policy and practice • Contributing to changes in social climate
Issues affecting the impact of research on policy and practice
Advantages of case studies • Provide comprehensive information about impact • Provide valuable examples of good practice and opportunities for lesson learning • Provide information about process as well as outcome • Provide feedback from a number of stakeholders
Practical and methodological considerations • Proportionality of effort • When should the case study be carried out? • Assessed impact of projects rather than programmes - could case studies be effectively used to assess the impact of programmes? • How much effort should be put into identifying final outcomes?
Further issues for HPD • What criteria should HPD use to assess impact? • What methods should be used?
