摘要

Introduction

Pharmacogenomics (PGx) tailors drug treatments to an individual’s genetic profile and contributes to improved efficacy and reduced adverse drug reactions. Community pharmacists have shown interest in PGx, and Dutch pharmacists have been early adopters in applying PGx guidelines, particularly through integration of the Dutch Pharmacogenetics Working Group recommendations. Despite growing evidence of its benefits, large-scale implementation in community pharmacies remains limited. This raises an important question for global stakeholders: if PGx adoption is constrained even in a system with robust infrastructure and guidelines, what lessons can be drawn for broader implementation?

Aim

To examine current PGx practices in leading Dutch community pharmacies and to identify key barriers, facilitators, and implementation strategies for integrating PGx into routine pharmacy care.

Method

A cross-sectional survey was conducted among Dutch pharmacy professionals with experience in PGx implementation. Participants were categorized as key opinion leaders (KOLs), involved in national PGx policymaking, research, or representing academia or professional organizations, or local champions (LCs), defined as practicing pharmacists directly involved in local PGx implementation in hospital or community pharmacies. The questionnaire was retrospectively mapped to Consolidated Framework for Implementation Research domains. Quantitative data were analyzed descriptively and qualitative responses were inductively thematically grouped to contextualize findings.

Results

Of the 67 invited professionals, 46 completed the questionnaire (response rate: 69%). Among respondents, 70% were LCs and 30% KOLs. Among KOLs (n = 14), the most frequently cited barriers included costs (79%, n = 11/14), inadequate Information and Communication Technology (ICT) support (29%, n = 4/14), and legal or regulatory uncertainty (29%, n = 4/14). A positive view on the clinical value of PGx was reported by 81% of LCs (n = 26/32) and 93% of KOLs (n = 13/14). Suggested facilitators by LCs included improved ICT infrastructure (56%, n = 18/32), enhanced education and training (44%, n = 14/32), and stronger interdisciplinary collaboration (25%, n = 8/32).

Conclusion

PGx implementation in Dutch pharmacies is hindered by structural barriers such as fragmented ICT and lack of reimbursement, despite strong professional support. Embedding PGx into pharmacy workflows and aligning policy, infrastructure, and education are essential. These findings may inform broader efforts to integrate PGx into pharmacies across diverse systems.
