ABSTRACT
Introduction
High-risk medications are medications associated with significant patient harm or death if misused or used in error. This study aimed to develop a national consensus high-risk medication list for use in Australian residential aged care.
Methods
A 3-round modified Delphi study involving Australian healthcare professionals was conducted. In Round 1, participants indicated their level of agreement, on a 9-point Likert scale, whether 60 medications/medication classes were considered high-risk and should be included in a high-risk medication list for Australian residential aged care. Round 2 included medications/medication classes that did not reach consensus and new medications identified by participants. Consensus was defined as 70% or more of participants responding at 7 or higher on the Likert scale. In Round 3, participants were asked to prioritise medications/medication classes that reached consensus in Round 1 or 2.
Results
In total, 42 participants completed Round 1, and 35 (83%) completed all three rounds. Participants included pharmacists (n = 21), prescribers (n = 15), nurses (n = 5) and a paramedic (n = 1), with representation from all Australian states and mainland territories. Overall, 26 medications reached consensus (21 in Round 1, five in Round 2) and were categorised into 15 medications/medication classes for prioritisation in Round 3. The final prioritisation list was opioids, insulin, benzodiazepines, anticoagulants, z-drugs, antipsychotics, lithium, sulfonylureas with high risk of hypoglycaemia, chemotherapeutic agents, methotrexate, digoxin, narrow therapeutic range antiepileptics, tricyclic antidepressants, immunosuppressants for transplant and sedating antihistamines.
Discussion
This is the first, national consensus list of high-risk medications developed specifically for Australian residential aged care. It can be used to implement targeted strategies to minimise medication-related harm.
