Medical hub reputation hurt by IVF mix-up

THE recent sperm mix-up during an in-vitro fertilisation (IVF) performed at the Thomson Medical Centre (TMC) was due to lapses in procedure and human error, said Health Minister Khaw Boon Wan yesterday.
The incident has not only 'hurt the reputation' of the centre's IVF facility, but it has also 'indirectly affected Singapore's reputation as a regional medical hub', he said in Parliament.
He was replying to a question by MP Lam Pin Min (Ang Mo Kio GRC), who had asked for the outcome of the Health Ministry's investigations into the botched procedure.
Earlier this month, it was reported that TMC's fertility centre had used the wrong sperm for an IVF procedure after the Health Ministry investigated a case of a baby whose DNA did not match the father's genes.
TMC was then suspended from all new assisted reproduction activities. It apologised for the mistake and pledged support to the affected couple - a Singaporean Chinese woman and her Caucasian permanent resident husband - who have since decided to keep the baby.
Mr Khaw explained that Assisted Reproduction Centres handle specimens from many couples. To eliminate the risk of any mix-ups, they follow procedures in line with international best practices.
First, the embryologist will work on the specimens of only one individual or couple, at one workstation at a time. Second, he will label all the receptacles and instruments with the couple's or individual's name.
Third, he will discard disposable instruments such as pipettes after each use to avoid contamination. Fourth, at every critical step, a second operator will counter-check that the specimens are transferred to the correct receptacles.
Mr Khaw revealed that at the time of the incident, the embryologist was processing semen specimens of two individuals at the same workstation at the same time. The pipette used for transferring the specimen was reused instead of being discarded after each step.
'Though it was reused only for handling the specimens from the same individual, it unnecessarily raised the risk of human error,' he said. There was also no one to counter-check that the specimens were transferred to the proper receptacles at each stage.
'The key is full disclosure of facts and immediate correction of any systemic inadequacies to ensure similar errors will not recur. This is the way to regain patients' confidence and trust,' said Mr Khaw.
