Digitalising Clinical Guidelines: The Challenge of Patient's Preferences.

Abstract

Will digitalised clinical guidelines be compatible with individualised and personalised patient care if the disease definitions and classifications used within them contain embedded preferences? Taking bone health as a case study, we found the dominant definition of osteoporosis installs the consensus preference judgement of a 1992 International Expert Committee in the form of a threshold cut-off on the bone mineral density continuum. We found that subsequent UK clinical guidelines follow suit on this diagnostic threshold, but also endorse preference-sensitive thresholds for interventions to prevent fractures, including ones underpinned by cost-effectiveness analysis. The resulting pre-emption of patient's preferences needs to be removed if 'computable' guidelines are to be reconcilable with personalised care. The challenges to be met in digitalisation therefore include major conceptual ones as well as the technical ones that are currently the almost exclusive focus.
