Background:
Medication review (MR) is the systematic assessment of a patient's medications for safety and effectiveness by a healthcare professional. The language used to describe MR activity, such as stopped medicine and increased dose, should be consistent across studies to assist researchers compare how different services operate and identify their mechanism of impact.
Aim:
To develop an international taxonomy of standardized terms and activity definitions related to medication reviews.
Method:
This was a three-stage Delphi-based consensus study with international medication review experts. A systematic review provided MR activity terms for the survey. Experts rated their consensus on each activity term and its definition on a Likert scale and provided written feedback. The consensus was 75% panel agreement. At each stage, consensus elements were retained, and feedback was used to revise definitions.
Results:
Seven experts were recruited for the study (response rate 15.2%) from four countries: the United Kingdom (n = 4), New Zealand (n = 1), Australia (n = 1), and Malaysia (n = 1). The following terms achieved consensus: the term Medication as a descriptor for MR terms; discontinue medication, start medication, dose increase, dose decrease, dosage form change, and medication safety and efficacy monitor to describe MR activity; Educate to describe the delivery of healthcare professionals and patients/carers education.
Conclusion:
Standardized medication review activity terms and definitions have been selected for universal adoption in all future MR research to facilitate a meaningful comparison of process evaluations within different settings.
Insights
Standardized terms for medication review activities were developed to improve research consistency. This international taxonomy will help compare medication review services and their impact effectively.
Area of Science:
- Pharmacology
- Health Services Research
- Clinical Pharmacy
Background:
- Medication review (MR) is a critical process for assessing drug safety and effectiveness.
- Inconsistent terminology in MR research hinders comparisons between studies and understanding of service impact.
Purpose of the Study:
- To establish an international taxonomy of standardized terms and activity definitions for medication reviews.
Main Methods:
- A three-stage Delphi consensus study involving international medication review experts.
- Systematic review to identify MR activity terms, followed by expert rating and feedback on a Likert scale.
- Consensus defined as 75% panel agreement, with iterative refinement of definitions based on feedback.
Main Results:
- Seven experts from four countries participated.
- Consensus was reached on terms including 'Medication' as a descriptor.
- Key MR activity terms agreed upon: discontinue medication, start medication, dose increase, dose decrease, dosage form change, medication safety and efficacy monitor, and Educate.
Conclusions:
- A standardized set of medication review activity terms and definitions has been selected for global adoption.
- This standardization will enable meaningful comparisons of process evaluations across diverse settings in future MR research.
