Randomized Controlled Trial Clinical TrialA comparison of two methods of follow-up in a trial of prophylactic volume expansion in preterm babies.
The outcome at age 2 years of preterm babies recruited into a three-arm randomised controlled trial of prophylactic volume expansion was ascertained in two ways: from a neurodevelopmental assessment performed by a paediatrician and from responses on a brief questionnaire completed by the child's personal health visitor. Of 776 babies recruited into the trial, 604 survived to the age of 2 years and the findings of a paediatric assessment were available for all survivors. Questionnaires were sent to the health visitors of 601 of the survivors; 513 (85.4%) were returned. ⋯ The end point of the trial was death or severe disability at 2 years of age. There was close similarity in the trial results whether based on the paediatric assessment or on the questionnaire. Further refinement of the questionnaire is needed, but this methodology may be useful in ascertaining the frequency of severe disability in large cohorts of babies.
