Objective: To develop information leaflets for older inpatients and/or their carers to support deprescribing of antipsychotics, benzodiazepines/Z-drugs and proton pump inhibitors (PPIs).
Design: An iterative mixed-methods approach involving face-to-face user testing and semi-structured interviews was performed over three rounds with consumers and hospital health professionals.
Setting: Sydney, New South Wales, Australia.
Participants: Thirty-seven consumers (or their carers) aged 65 years or older admitted to hospital in the previous 5 years and taking at least one regular medicine (not the medicine tested) completed user testing. Health professionals included a convenience sample of seven pharmacists and five doctors.
Methods: The antipsychotic leaflet was tested in round 1 (consumers, n=10) and revised and retested in round 2 (consumers, n=9; health professionals, n=5). Findings from rounds 1 and 2 informed the design of the benzodiazepine/Z-drug and PPI leaflets tested in round 3 (benzodiazepine/Z-drug consumers, n=9; health professionals, n=7; PPI consumers, n=9). Findings from round 3 informed the final design of all leaflets. Consumer user testing involved 12-13 questions to evaluate consumers' ability to locate and understand information in the leaflet. Usability by health professionals was assessed using the System Usability Scale (SUS).
Results: At least 80% of consumers correctly found and understood the deprescribing information in the leaflets (9 of 12 information points in round 1 (antipsychotic); 10 of 12 in round 2; 12 of 13 (benzodiazepine/Z-drug) and 11 of 12 (PPI) in round 3). Consumers perceived the leaflets to be informative, well-designed and useful aids for ongoing medication management. The SUS scores obtained from health professionals were 91.0±3.8 for the antipsychotic leaflet and 86.4±6.6 for the benzodiazepine/Z-drug leaflet, indicating excellent usability.
Conclusions: Understandable and easy-to-use consumer information leaflets were developed and tested by consumers and health professionals. The feasibility and utility of these leaflets to support deprescribing at transitions of care should be explored in clinical practice.
