Summary

A doctor who practiced in Australia from 2018 to 2022 has been found to have committed professional misconduct, with thousands of patients advised to repeat their colonoscopies due to concerns about her methods. According to an investigation, out of 1,084 patients who re-took the procedure, 548 had polyps and seven had cancer. The doctor's conduct was reported by an independent expert who said that a patient may have developed stage 4 bowel cancer after receiving a sub-par colonoscopy from Dr Liu-Ming Schmidt in 2021. The case has raised questions about the quality of care provided during some of these procedures, with one gastroenterologist describing a particularly short procedure as "not appropriate".

Story summary

Dr Liu-Ming Schmidt, a doctor who was suspended from practicing in July, oversaw thousands of flawed colonoscopies at three health services between 2018 and 2022. A total of 1,934 patients were advised to repeat their procedure after concerns arose about Dr Schmidt's methods. Of the 1,084 patients who underwent a re-test, 548 had polyps and seven had cancer. One patient, Lynette Taylor, was forced to question her faith in Dr Schmidt after discovering that she had not identified several polyps during Lynette's colonoscopy at Albury Wodonga Private Hospital in 2021. The discovery of the flawed procedures has sparked criticism from patients and advocates who argue that the suspension handed down to Dr Schmidt was too lenient.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
