Quality Data Management in HIV Clinical Trials
are averaged under the null hypothesis to give Formula 3: (3)where p is the average of pi and and q. Because research organizations must create their own standard procedures, its not always clear how your organizations data management practices compare to peer organizations. Electronic Data Capture (EDC) technology has had a further impact, as paper CRFs typically leveraged for quality measurement are not used in EDC processes. Introduction, research sponsors and clinical research organizations (CROs) are transitioning from paper-based data collection to electronic data capture (EDC) systems. We hypothesized that for EDC to substantially improve quality, it would have to facilitate improvements to the process of medical record abstraction. Eur Respir J 14: 150154. Most sites with error rates below this benchmark that also addressed data queries and protocol violations in a timely manner would not receive additional audits, although one site would be chosen at random for a second audit. Can J Public Health 91: 390393.

These involve quarterly meetings that emphasize peer interactions and learning. . Find the right system for your operational needs. The first CI-based method is for comparison of an error rate to a standard. Instead, we compared sites within a trial and performed an assessment, described here, early in the program to investigate the applicability of a CTN-wide acceptance criterion. The error rate denominator was the number of fields actually audited, excluding those defined ernest Hemingway: Male Bonding as system-calculated or propagated fields. Tennis P, Bombardier C, Malcolm E, Downey W (1993) Validity of rheumatoid arthritis diagnoses listed in the Saskatchewan Hospital Separations Databse. Based on observed error rates, one audit visit per site may be sufficient, as statistical power remains suffices for determining the data quality of the trial as a whole as well as at each site.

If novel technologies are to be successfully integrated into clinical trials, their effects on data quality must be fully understood. Purpose The National Institute on Drug Abuse (nida) Clinical Trials Network (CTN) has instituted a process for quantifying data quality on EDC trials. The system facilitates extensive error checking for missing, out-of-range, and logically inconsistent values across the CRF in real time so that many potential errors are caught prior to final data submission.
