The International Consortium for Evidence-Based Perfusion (ICEBP) is a collaborative group whose mission is to improve, continuously, the delivery of care and outcomes for patients undergoing cardiac surgery. To achieve this end, the ICEBP supports the development of perfusion registries to evaluate clinical practices and has established evidence-based guidelines for perfusion. The Japanese Society of Extra-Corporeal Technology in Medicine (JaSECT) developed a perfusion registry to examine variation in perfusion practice in Japan. A pilot study was designed to determine the rate and accuracy of data extraction from patients' medical records and perfusion practice records and the subsequent entry of data into the registry form. We designed an input matching test using medical records and perfusion records from a sample of patients. Five institutions participated in data extraction and entry from 10 randomly selected case records. Perfusionists entered data in the registry form in accordance with the instruction manual prepared by the JaSECT guideline committee. The time taken to input every case in the registry was measured. An interview-based survey was carried out across institutions after the completion of the pilot. The time required for data entry stabilized after approximately five cases to a rate that was 40% of the first case entry time. Data entered into the registry by perfusionists for multiple-choice items were accurate 65% of the time and accurate 25% of the time for numerical data. The interview-based survey identified a total of 38 opportunities for improvement in the input form and 58 recommended changes for the instruction manual. The accuracy of data may be improved by developing a method allowing the objective detection of deficient data when present in the perfusion case record by developing automatic data acquisition from the automatic perfusion recording system currently in use, and by changing as many numerical value input items as possible to multiple-choice items.
