Deprescribing Tool for Older PeoPle with Limited-life Expectancy (De-TOPPLE) version 1: Development and validation...

Deprescribing decision making in older adults with limited life expectancy is often challenging for clinicians. We aimed to develop and validate a Deprescribing Tool for Older People with Limited-life Expectancy (De-TOPPLE). Modified Delphi technique was used to gain experts' consensus on the tool and further develop using their feedback. Experts [Round-1 (n = 13), Round-2 (n = 7)] had clinical and/or research background on geriatric medicine, geriatrics, family medicine or pharmacotherapy. Round-1 consensus was achieved on approach taken by the tool to evaluate risk and benefit; distinguishing medications as preventive, symptom control or dual-purpose; referring to established deprescribing process; stepwise approach to deprescribing; and the overall concept. Common feedback was to reflect upon harm-benefit analysis, distinguish medication types earlier, qualify adverse events, use time-to-benefit (TTB), prioritise symptom relief, monitor post-deprescribing, include shared decision making and define terms for clinical familiarisation. After tool update, Round-2 consensus was achieved on usability in clinical setting, flexibility of implicit judgement, ceasing preventive medication with inadequate TTB, ceasing symptom control medication with inadequate symptom relief, ceasing dual-purpose medication (DPM) with inadequate TTB and symptom relief, and continuing DPM with adequate TTB and symptom relief. De-TOPPLE version 1 was developed and validated through two rounds of the Delphi process. Clinical use of the tool needs final validation following the addition of contextual statements to the tool.
