A doctor tested a woman's cervix, but then failed to act on the abnormal lab result until queried by the National Cervical Screening Programme more that six weeks later.
The unnamed overseas-trained doctor has been found in breach of the code of patients' rights by Health and Disability Commissioner (HDC) Anthony Hill, in a decision made public today.
Cervical smear testing is done to detect cells that could indicate cancer or potentially pre-cancerous abnormalities.
The doctor has been told to write an apology to the woman, who was 38 at the time. He also must make a random audit of his clinical records to ensure that patients' test results in the last two years have been followed up properly and that the patients have been advised of the results.
The cervical smear was taken on October 11, 2013. The lab results were reported to the doctor's medical management system inbox eight days later. He told Hill's inquiry he did not recall seeing the result in his inbox, but thought he must have viewed and then probably filed it.
