Abstract

BACKGROUND:

Incident reporting systems are useful tools to raise awareness of patient safety issues associated with healthcare error, including errors associated with the medical laboratory.

METHODS:

Previously, we presented the analysis of data compiled by the British Columbia Patient Safety & Learning System over a 3-year period. A second comparable set was collected and analyzed to determine if reported error rates would tend to remain stable or change.

RESULTS:

Compared to the original set, the second set presented changes that were both materially and statistically significant. Overall, the total number of reports increased by 297% with substantial changes between the pre-examination, examination and post-examination phases (χ2: 993.925, DF=20; p<0.00001). While the rate of change for pre-examination (clerical and collection) errors were not significantly different than the total year results, the rate of change for reporting examination errors rose by 998%. While the exact reason for dramatic change is not clear, possible explanations are provided.

CONCLUSIONS:

Longitudinal error rate tracking is a useful approach to monitor for laboratory quality improvement.
