ABSTRACT
The Japanese adult cardiovascular database (JACVSD) contains details of all adult cardiovascular surgeries performed in Japan. This database has the potential to make data from all of Japan available to the world in the future. However, it is time consuming to enter several items from an individual terminal for all cases ; adding further pressure to already busy routine work. In our facilities, an original system using Filemaker Pro has been developed and used since 2004. This system has various functions integrated into it, and currently, the input system of JACVSD has been added. As a result, it becomes possible to automatically enter more than half the data of JACVSD, and excellent results can be reported. Intellectual property rights have been owed by Nihon University since 2007.
ABSTRACT
Recently, the use of databases for clinical trials is being promoted. We used the Japan Adult Cardiovascular Surgery Database (JACVSD) data was used as a historical control in a clinical trial, and we analyzed following : the processes of using data and the efficiency of data collection, available variables for statistical analysis, and query functions for missing and invalid data. We chose available variables of JACVSD data and created rules for merging JACVSD data with interventional group data, in addition to analyzing the data collection processes for clinical trials. Subjects were selected from cases registered in the JACVSD. On statistical analysis, 63% of 76 variables were used ; variables related to the patients' symptoms had to be collected separately. Missing and invalid data were effectively excluded. We could conduct data collection efficiently by using the JACVSD as a historical control for clinical trials. Selecting subjects from the JACVSD could reduce the burden of selecting subjects from hospitals and prevent selection bias.
