Effectiveness of an Arabic CPIC-Based Pharmacogenomics Microlearning Program on Community Pharmacists' Clinical Decision-Making in Jordan

Pharmacogenomics (PGx) presents a vital opportunity to optimize medication safety, yet community pharmacists often lack the applied clinical training required to interpret and act upon genetic data. This study aimed to evaluate the effectiveness of an Arabic Clinical Pharmacogenetics Implementation Consortium (CPIC)-based microlearning program on the clinical decision-making, knowledge, confidence, and readiness of community pharmacists in Jordan.

Inclusion Criteria: * Participants had to be licensed pharmacists working in a community pharmacy in Jordan * Participants had to be capable of comprehending the Arabic language * Participants have access to internet-enabled devices (smartphones, tablets, computers) * Participants give informed consent electronically and agree to take all assessments longitudinally (baseline, immediate post-intervention, and follow-up four weeks later). Exclusion Criteria: * Participants having an advanced postgraduate specialty or previous training in PGx (This criteria helps eliminate the problem of ceiling effect in order to evaluate the intervention as intended for a specific target audience: community pharmacists without advanced precision medicine training.) * Participants being involved in PGx research, curriculum development, and/or delivering PGx services * Participants providing incomplete baseline surveys * Participants withdrawing from the study before randomization. These exclusions were purposefully designed to mitigate baseline expertise bias and ensure the sample accurately reflects the broader, non-specialized community pharmacy workforce.
