To ground our arguments, we present findings from an ethnomethologicallyinformed ethnographic study carried out in the context of the clinical trial of a computerbased aid in medical work. Our findings highlight the problematic nature of traditional clinical trials for evaluating healthcare technologies, precisely because such trials fail to grasp the situated, social and collaborative dimensions of medical work.enText10.1007/978-94-010-0068-0_20
