Health practitioners' perceptions of the barriers and enablers to the implementation of reproductive genetic carrier screening: A systematic review.

ABSTRACT

BACKGROUND: As interest in reproductive genetic carrier screening rises, with increased availability, the role of healthcare practitioners is central in guiding uptake aligned with a couples' values and beliefs. Therefore, practitioners' views on implementation are critical to the success of any reproductive genetic carrier screening programme. AIM: To explore healthcare practitioners' perceptions of the barriers and enablers to implementation. MATERIALS & METHODS: We undertook a systematic review of the literature searching seven databases using health practitioner, screening and implementation terms returning 490 articles. RESULTS: Screening led to the inclusion of 26 articles for full-text review. We found three interconnected themes relating to reproductive genetic carrier screening (i) use and impact, (ii) practitioners' beliefs and expectations and (iii) resources. DISCUSSION: Barriers and enablers to implementation were present within each theme and grouping these determinants by (a) community for example lack of public interest, (b) practitioner for example lack of practitioner time and (c) organisation for example lack of effective metrics, reveals a preponderance of practitioner barriers and organisational enablers. Linking barriers with potential enablers leaves several barriers unresolved (e.g., costs for couples) implying additional interventions may be required. CONCLUSION: Future research should draw on the findings from this study to develop and test strategies to facilitate appropriate offering of reproductive genetic carrier screening by healthcare practitioners.
