BackgroundMaking a meaningful decision on deprescribing of potentially inappropriate medications in older adults with life-limiting illnesses (LLIs) and limited life expectancy (LLE) is often challenging. Therefore, we aimed to elicit opinion and gain consensus on a deprescribing tool for use in this population.Methods and analysisA modified-Delphi method will be used to obtain a consensus from a panel of experts in geriatric therapeutics on a deprescribing tool for use in people aged ≥65 years with LLIs and LLE. Through an online survey, in the initial round, the panel will anonymously elicit their opinion on a series of items related to the conceptual model of the deprescribing tool, its practicality and deprescribing of medications, while on the controlled feedback in subsequent rounds till a consensus is reached or the panellists stop revising their answers. In each round, panel members will be using a 5-point Likert scale to rate their agreement with the statement. Consensus will be considered on ≥75% of agreement on the statements.Ethics and disseminationAll the participants will receive an invitation and participant information but they need to consent for the participation. Ethics approval has been granted from the University of Queensland Health and Behavioural Sciences, Low and Negligible Risk Ethics Sub-Committee (reference: 2020001069). The results of this project will be disseminated through conferences and a peer-reviewed clinical journal.
