Does logical checking function increase the accuracy of data entry in the patterns of care study?
The data accuracy was improved by using the computer database more extensively than the conventional case report form. By adding the logical checking function to the PCS database, significant improvement in the accuracy of data entry was accomplished. This indicates the potential for increasing the accuracy of data capturing with the aid of a computer.
