- Abstract
Background: Using routinely collected clinical data for observational research is becoming a popular method for data collection, especially for outcomes that are rare events. The POOL study was commissioned to evaluate the safety of waterbirth in the UK using routine maternity and neonate clinical data. This paper sets out the design rationale, set-up and data collection pilot for this bespoke data linkage study. Methods: Wellbeing Software®, provider of the Euroking® information system was selected to add new variables to their information system, extract study data from participating NHS sites and transfer data for matching with the National Neonatal Research Database (NNRD). The data extraction, linkage and cleaning was piloted with the first NHS site set-up to confirm data could be linked to the NNRD, identify steps for data management and cleaning, assess data completeness for new and key data fields and develop a plan for a risk classification algorithm. Results: Twenty six sites were set-up over a # months. Twenty-four thousand records were extracted from the pilot NHS site, pertaining to the period from January 2015 to March 2019. Data field completeness for maternal and neonatal primary outcomes were assessable, although some data fields’ completion had been identified as less than adequate. Data flowed to the NNRD enabling matching and linkage between maternal and neonate data. Discussion: Piloting the data extraction and linkage has been a useful exercise which highlighted the need for additional documentation, training and processes to ensure data quality and confidentiality are upheld for the remainder of the study. Accessing such data on scale, is possible, but continues to be a time consuming and a technically challenging exercise.
