Objectives:
1) To understand and investigate the experiences of accredited clinical pharmacists (ACP) using computerised clinical decision support systems (CCDSS) during medication reviews for older people, including those living with dementia; 2) To design, develop, validate, and evaluate a CCDSS that incorporates pharmacological and other deprescribing tools to aid person-centred management of high-risk medications in older adults living with and without dementia.
Methods:
This study consisted of three phases and was designed on scenario-based methodology: a) the development phase, which included an exploratory survey and prototype building; b) the validation phase, which included qualitative data collection and usability testing with ACPs, general practitioners (GPs) and carers for people living with dementia; and c) the evaluation phase, using mixed-methods analyses.
Results:
The exploratory survey found that ACPs required a flexible, and reliable CCDSS to support them with clinical decisions regarding high-risk medication use in older adults. The Goal-directed Medication review Electronic Decision Support System (G-MEDSS)© was developed and validated using quantitative and qualitative feedback received from ACPs, GPs and carers for people with dementia. The mean (SD) System Usability Scale score was 69.0 (12.9), which indicated fair-good usability.
Discussion And Conclusions:
Involving end-users in the design process refined and improved the design of G-MEDSS, allowing for a person-centred and goal-directed delivery of pharmaceutical care. G-MEDSS allows healthcare practitioners conducting medication reviews for older adults living with and without dementia to tailor pharmaceutical care to meet their goals and preferences. Future studies may explore integration of G-MEDSS with prescribing or dispensing software.
