Development of consumer information leaflets for deprescribing in older hospital inpatients: a mixed-methods study.

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.
