In the week since Seattle Children’s Hospital revealed to the public that the required cleaning processes for instruments at their Bellevue Clinic and Surgery Center were not consistently followed, there have yet to been any confirmed infections found in the hundreds of patients tested so far.

Seattle Children’s reported that they have tested more than 300 patients, and have found no confirmed infections related to the sterilization problem.

“We’ve already been contacted by a lot of proactive parents, and some parents have already brought kids to our hospitals, but we are also giving out lab forms that they can take to their own providers to get the tests if they choose,” said hospital spokesperson Stacey DiNuzzo.

The hospital began sending out letters to around 12,500 patients who could potentially be at risk on Aug. 31.

“We do not know exactly how many patients might be impacted, but we are currently reaching out to approximately 12,000 patients who were seen at Bellevue Clinic and Surgery Center for surgical procedures. We are also notifying patients and families who had procedures at Seattle Children’s Everett (not The Everett Clinic) and Mill Creek regional clinics,” the hospital said in a statement.

As the Reporter previously reported, Seattle Children’s discovered a lapse in their sterilization process in their Bellevue clinic.

Staff reportedly noticed “debris” in packaged instruments taken off of a shelf in the clinic, prompting the investigation. Initial findings have shown that the steam sterilization step, which is the last step in the process, was working properly.

As a result of the problems with sterilization, patients who had a surgical procedure at the Bellevue Clinic may need to be tested for hepatitis B and C, as well as HIV. The risk, however, is extremely low, the hospital said.
