Insights
Genomic newborn screening (gNBS) can expand public health benefits by identifying more conditions. Key actions include educating providers and offering psychosocial support, while addressing consent and result disclosure are crucial for successful implementation.
Area of Science:
- Genomics
- Public Health
- Pediatrics
Background:
- Newborn screening (NBS) is a vital public health intervention.
- Genomic sequencing (gNBS) can enhance NBS by screening for more conditions.
- Implementation strategies for gNBS require careful planning.
Purpose of the Study:
- To identify necessary actions, actors, context, timing, and targets for genomic newborn screening (gNBS).
- To explore perceived barriers and enablers for implementing gNBS.
- To inform population-scale delivery of gNBS.
Main Methods:
- Utilized the Actor, Action, Context, Time, and Target (AACT) framework.
- Conducted interviews with 20 key informants involved in NBS delivery.
- Analyzed data to identify required modifications and new actions for gNBS.
Main Results:
- New actions include educating healthcare providers and providing psychosocial support.
- Modifications needed for obtaining consent and timing of result disclosure.
- Genetic counselor workforce limitations pose a potential barrier, while online tools are enablers.
Conclusions:
- Successful gNBS implementation requires behavior change from healthcare providers.
- Addressing consent and result disclosure timing is critical for gNBS programs.
- Findings provide a roadmap for scaling gNBS delivery effectively.
Abstract:
Newborn screening (NBS) programmes are highly successful, trusted, public health interventions. Genomic sequencing offers the opportunity to increase the benefits of NBS by screening infants for a greater number and variety of childhood-onset conditions. This study aimed to describe who needs to do what, when, and for whom to deliver genomic newborn screening (gNBS) and capture perceived implementation barriers and enablers. 'Key informants' (individuals involved in the delivery of NBS) were interviewed. The Actor, Action, Context, Time and Target framework guided data collection and analysis. Participants (N = 20) identified new Actions required to deliver gNBS (educating healthcare providers, longitudinal psychosocial support), NBS Actions needing modification (obtaining consent) and NBS Actions that could be adopted for gNBS (prompt referral pathways). Obtaining consent in a prenatal Context was a source of some disagreement. The Time to disclose high chance results was raised as a key consideration in gNBS programme design. Genetic counsellors were identified as key Actors in results management, but workforce limitations may be a barrier. Online decision support tools were an enabler to offering gNBS. The implementation of gNBS will require behaviour changes from HCPs delivering NBS. Findings can inform how to deliver gNBS at population-scale.
