Intervention elements and behavior change techniques to improve prescribing for older adults with multimorbidity in Singapore: a modified Delphi study

​Purpose

Potentially inappropriate prescribing among older adults is a rising concern, attributed mainly by polypharmacy and multimorbidity. We aimed to identify key components and strategies for construction of a context-relevant intervention to facilitate appropriate prescribing in outpatient clinics in Singapore.

Methods
The modified Delphi study was conducted in two rounds with 20 geriatricians from seven public hospitals in Singapore. Round one survey presented 69 statements formulated from a scoping review, while round two presented 23 statements with some modifications based on round one comments. The statements were rated against a 7-point Likert scale on their importance and impact on prescribing for older adults with multimorbidty.

Results
Consensus were achieved for 90% of the statements. Seven intervention elements were identified as being important: medication review, training, medication therapy management, shared decision making, patient interview, medication reconciliation, comprehensive geriatric assessment. In addition, some commonly identified behavior change techniques included goal setting (behavior), goal setting (outcome) and problem solving.

Conclusions
This study identified important intervention elements and their potential strategies that could be adopted in an intervention to optimize appropriate prescribing for older adults with multimorbidity.
