Approximately one-third of patients did have >10% reversible risk, however, so that it may be rational to treat specific patients at specific times, particularly if the electronic medical record permits entry of data in a risk calculation "engine" based on glucose, blood pressure, lipids, cigarette use, obesity, and aspirin use, allowing specific recommendations for specific patients.
The Principal Investigator is responsible for overseeing entry of data into an in-house password protected electronic system and ensuring data accuracy, consistency and timeliness.
The electronic forms of data entry were variable, utilizing push button technology[ 33, 36], or touch sensitive screens using a stylus pen [ 34, 37- 39].
An electronic system of data entry called OpenClinica® was selected and a proper clinical research form (CRF) was designed for the input of data after the questionnaire of each case was completed and reviewed.
We adopted a double entry system of data entry.
Electronic capture of data will allow for rapid Web-based entry and will minimize difficulties inherent in the process of data transfer from paper to electronic databases.
Ideally, the handheld system should be integrated with the hospital electronic patient record, allowing direct entry of demographic data as well as access to laboratory data.
Electronic methods of data collection have been developed in order to merge the process of data collection and data entry [ 2].
Therefore this data is highly heterogeneous and the method of input may be any combination of standardized electronic entry, paper entry, or manual entry for a given field.
XML-based data standards are useful when it comes to electronic database storage of data as they are highly extensible, flexible and all data entries are labelled.
