Point-of-care outcome assessment in the cancer clinic: Audit of data quality

Background and purposeTo assess the completeness and accuracy of stage and outcome data in the Anthology of Outcomes (AOs), a prospective point-of-care physician-collected electronic data system for patients at the Princess Margaret Hospital.Material and methodsA random sample of 10% of the AO cases registered between July 2003 and December 2005 was drawn. An audit was conducted of the AO data compared with chart review and cancer registry.ResultsThe AO system was applied first to a head and neck (HN) cancer patient cohort. From 1152 HN cases, 120 were audited. TNM stage was recorded in all cases. Discrepancy was found between the AO and primary data sources in 3–13% of cases. Physician review showed a 3% error rate in overall stage recorded in the AO. Sixty-two outcomes in 43 patients were found on chart review. No outcomes were incorrectly recorded in the AO. Nineteen (31%) outcomes in 17 patients were missed in the AO.ConclusionsOur experience has demonstrated the feasibility of real-time outcome recording at point-of-care. New processes needed to improve the completeness of capture of patient outcomes in the AO have more recently been introduced. This successful system has been expanded to other disease sites.
