Implementation of Pharmacogenetics in Primary Care: A Multi-Stakeholder Perspective

Area of Science:

• Pharmacogenomics
• Primary Care Medicine
• Clinical Implementation Science

Background:

• Aberrant pharmacogenetic variants affect drug metabolism in many individuals.
• Early identification of pharmacogenetic profiles can predict drug efficacy and safety.
• Slow implementation of pharmacogenetics in primary care limits public health impact.

Purpose of the Study:

• To define actions, roles, and responsibilities for integrating pharmacogenetics into primary care.
• To identify barriers and facilitators for pharmacogenetic testing implementation.
• To prioritize actions for routine pharmacogenetic application.

Main Methods:

• A three-step mixed-methods approach involving focus groups, interviews, an expert meeting, and a Delphi study.
• Stakeholder consultation with pharmacists, physicians, and patients.
• Prioritization of implementation actions using an online Delphi Study.

Main Results:

• Lack of clinical utility evidence, reimbursement issues, and data sharing challenges were identified as key barriers.
• Unclear roles and responsibilities between general practitioners and pharmacists were noted.
• Sixteen actions were formulated, with nine remaining pertinent after Delphi ranking, but low agreement on prioritization was observed.

Conclusions:

• Stakeholders formulated necessary actions for pharmacogenetics integration in primary care.
• Lack of consensus on action prioritization hinders widespread implementation.
• Coordinated efforts among stakeholders are crucial for effective pharmacogenetic integration.
