However, against a background of increasing demands on limited resources and the need to maximise the benefits of additional health service investment, the focus has shifted to cost-effectiveness.2Building on these developments, national frameworks were developed to define skills, competencies and governance but primary care organisations were encouraged to develop innovations in service delivery based on local need.3 However, despite the policy rhetoric, the initiative has developed considerable momentum without any evidence base.The randomised controlled trial by Baker et al4 in this month's Journal (page 912) showing no differences in clinical outcomes between orthopaedic hospital and practice-based clinics reflects an early and developing evidence base of the effectiveness of GPwSIs. With the shift in emphasis to decision making at a local level, a key question is how the evidence base can be developed to support policy decisions in a way that is relevant to local health economies.The evaluation of public policy is set across a spectrum of approaches.The dominant analytical framework for health policy research reflected in Baker et al's study is known as a rational approach.
