"Human error" and inadequate quality control contributed to the inaccurate test results that wrongly classified patients at Khoo Teck Puat Hospital (KTPH) as having a more aggressive form of breast cancer, a review committee said on Monday (May 3). At least 200 patients were affected by the errors, which took place over eight years at KTPH's Department of Laboratory Medicine, Anatomic Pathology Section. About half of them may have received unnecessary treatment. "The calibration error was not discovered due to a failure to conduct rigorous checks at the point when the protocol was established." Independent investigations by the National Health Group (NHG) Review Committee also showed "inadequacies" in the section's quality control. This inadequate quality control and assurances contributed to the failure to detect the overstaining issue early and over the years when tests were conducted. Source: CNA., 2021.
