Objective: To explore the effect of research ethics, governance and consent requirements, and recent reforms, on UK-wide follow-up of children with congenital heart defects (CHD).
Design: Prospective cohort study.
Setting: UK National Health Service.
Patients: 3,897 children with CHD requiring intervention, or resulting in death, before one year old (1993-95).
Main outcomes: Impact on study protocol, timeliness and findings of a multicentre study of survival and quality of life.
Results: The peer-reviewed study protocol was altered to accommodate ethics committee stipulations that researchers should not approach families directly with a request to participate and that the general practitioner’s (GP) permission be sought before the local clinician could do so. Individual consent was required to confirm vital status of participants and for future tracing of public death registrations. Local study registration took a median 40 weeks (IQR 25-57). 180 (24%) of 739 surviving children (5 centres) could not be contacted because their GP was untraceable (32), had changed (128) or considered contact inappropriate (20). Invitations could not be sent to 31% from the most deprived compared with 17% from the least deprived areas.
Conclusions: Decision-making about childhood interventions should be influenced by evidence about long-term outcomes, however current UK research regulations are an impediment to follow-up in multicentre studies. Stipulations preventing researchers contacting families directly with research invitations appear disproportionate to the risks, impede equitable access to research opportunities and introduce bias. The requirement for an individual’s consent to confirm whether they are alive and monitor survival precludes effective long-term follow-up.
