Under Careful Construction: Combining Findings, Arguments, and Values Into Robust Health Care Coverage Decisions
Abstract Background: Health care coverage decisions deal with health care technology provision or reimbursement on a national level. The coverage decision outcome, i.e., the publicly available document with reasons for the decision, may contain various elements: quantitative calculations like cost and clinical effectiveness analyses and formalised and non-formalised qualitative considerations. We know little about the process of combining these heterogeneous elements into robust decision outcomes.Methods: In this study, we describe a model for combining different elements into coverage decision outcomes. We build on two qualitative cases of coverage appraisals at the Dutch National Health Care Institute, for which we analysed observations at committee meetings (n=2, with field notes taken) and analysis of audio files (n=3), interviews with appraisal committee members (n=10 in seven interviews) and with Institute employees (n=5 in three interviews).Results: We conceptualise decision outcomes as combinations of elements, specifically (quantitative) findings and (qualitative) arguments and values. Our model contains three steps: 1) identifying elements; 2) designing the combinations of elements, which entails articulating links, broadening the scope of designed combinations, and black-boxing links; and 3) testing these combinations and choosing one as the final decision outcome. Conclusions: The proposed model highlights decision makers’ expertise in composing both elements and combinations. It also provides additional rationales for facilitating appeals and engaging patients and the public. Future research efforts could further explore the relationship between robustness and decision combination strength.
