Implementing clinical ethics committees as a complex intervention: presentation of a feasibility study in community care

Abstract

BackgroundHow should clinical ethics support services such as clinical ethics committees (CECs) be implemented and evaluated? We argue that both the CEC itself and the implementation of the CEC should be considered as ‘complex interventions’.Main textWe present a research project involving the implementation of CECs in community care in four Norwegian municipalities. We show that when both the CEC and its implementation are considered as complex interventions, important consequences follow – both for implementation and the study thereof. Emphasizing four such sets of consequences, we argue, first, that the complexity of the intervention necessitates small-scale testing before larger-scale implementation and testing is attempted; second, that it is necessary to theorize the intervention in sufficient depth; third, that the identification of casual connections charted in so-called logic models allows the identification of factors that are vital for the intervention to succeed and which must therefore be studied; fourth, that an important part of a feasibility study must be to identify and chart as many as possible of the causally important contextual factors.ConclusionThe conceptualization of the implementation of a CEC as a complex intervention shapes the intervention and the way evaluation research should be performed, in several significant ways. We recommend that researchers consider whether a complex intervention approach is called for when studying CESS implementation and impact.
