Development and Delphi validation of a Best Possible Medication History form.

ABSTRACT

OBJECTIVE: To develop and validate a standardized Best Possible Medication History (BPMH) form that could be used by clinical pharmacists. METHODS: The draft version was presented to a focus group and was adapted following their comments. A three-rounds e-Delphi method was used to validate content, usability and face validity of the BPMH form. We supplemented the quantitative analysis with a qualitative analysis of comments for each Delphi round. RESULTS: The draft BPMH form contained 23 items grouped into eight tabs. Refinement of these tabs and items by the focus group resulted in 7 tabs and 21 items, which were included in the Delphi survey. The consensus was obtained for all tabs within the second round (p=0.072). Consensus was reached on 76% (16/21) of items in the third round. 20 items were included following the qualitative analysis of the experts' comments in the third round. CONCLUSIONS: The findings of this study provide data on the content of the BPMH form. This form can be used to help clinical pharmacists to collect a complete and accurate medication list on admission. It could have an impact on inpatient safety and improve inpatient management. Studies with an international e-Delphi should be conducted for wider use.
