Regional Follow up of Late Preterm Neonatal Intensive Care Graduates: Methodological Considerations.

The aim is to guide researchers who are contemplating embarking on research by discussing the methodological challenges encountered in a retrospective follow-up study of three-year-old, late preterm infants (LPIs) who received neonatal intensive care (NIC) in Northern Ireland in 2006. The importance of effective research examining the longer term outcomes of infants admitted to NIC has received increasing recognition. Follow-up cohort and longitudinal studies have grown in number globally, yet the research methodology relating to follow up of NIC graduates is unclear. This paper highlights the methodological challenges of conducting retrospective follow-up research, from the initial planning stages through to the collection of data from the children, including identification of infants from a retrospective database, ethical issues, child-safety concerns and recruitment challenges. This paper creates an awareness of potential issues that may arise in follow-up research with NIC graduates. The paper also offers practical and effective examples of dealing with these issues, helping to ensure the smooth running of an ethical, professionally conducted, methodologically sound and clinically relevant follow-up study.
