PurposeEvidence summary resources are popular with clinicians but it is unknown whether they can influence clinical decision making. We evaluated whether an extremely condensed and explicit evidence summary tool could influence clinical decision making.Materials And MethodsAn evidence summary tool was developed using a formal mapping exercise and graphic design principles. An invitation to participate was sent to subscribers of a critical care e-mail discussion list. Participants received a study package (evidence summary tool précising prone positioning in severe ARDS; case-based scenario describing a patient with severe ARDS plus evaluation questionnaire). Influence on clinical decisions was captured regarding six competing interventions, with Belief in benefit measured before and after reading the summary tool.ResultsAmong 93 participants, 87% were male with a mean age of 49.6(SD9.3) years. Mean ICU experience was 20.0(SD9.9) years. The evidence summary tool significantly influenced clinical decision making: belief in benefit of prone positioning increased (P < .001), belief in benefit of higher PEEP decreased (P = .002) and belief in benefit in ECMO decreased (P = .07).ConclusionsUsing a before-after evaluation, we demonstrated an extremely condensed and explicit information format can influence clinical decision making. Evidence summary tools may be a useful adjunct to support closing evidence-practice gaps.Copyright © 2019 Elsevier Inc. All rights reserved.
