A hospital in Manchester, N.H., has notified eight patients who may have been exposed to Creutzfeldt-Jakob disease from neurosurgery instruments.
Catholic Medical Center and the New Hampshire Department of Health and Human Services said this week that a patient who died after neurosurgery at the 233-bed hospital was suspected of having sporadic Creutzfeldt-Jakob disease.
“There is an extremely small chance that eight patients who had neurosurgery using this equipment may have been exposed to CJD,” the state health department said in an online statement (PDF)
. “This risk is very small, but exists, so these patients have been informed.”
The autopsy report, which would be used to confirm a Creutzfeldt-Jakob disease diagnosis, will take several weeks, Dr. Joseph Pepe, president and CEO of Catholic Medical Center, wrote in a separate letter
posted Sept. 5 to the hospital's website. Pepe said the at-risk patients were identified by the hospital and the health department after they reviewed their medical records.
Creutzfeldt-Jakob disease is a fatal brain disorder caused by a rare type of protein called a prion, which resists standard sterilization processes used by hospitals.
About 200 people a year are diagnosed with the disease in the U.S. However, there are only four confirmed cases of patients contracting the disease from surgical instruments, and none occurred in the U.S., the New Hampshire health department said. The use of surgical instruments in brain, eye and spinal cord procedures are the most risky.
The health department said Catholic Medical Center tracks the use of surgical medical equipment in patients as required by the Joint Commission and adheres to sterilization guidelines established by the Association for the Advancement of Medical Instrumentation.
Lisa Waldowski, an infection control specialist for the Joint Commission, which accredits the quality and safety of healthcare providers, said the commission expects hospitals to track the use of medical equipment in patients and expects hospitals that offer surgical services to have a prion processing protocol in place.
In 2001, the Joint Commission issued a sentinel alert (PDF)
recommending that hospitals establish a policy for disinfecting or disposing of neurosurgery instruments when Creutzfeldt-Jakob disease is suspected or confirmed. The recommendation came after two hospitals in Denver and New Orleans
notified patients that they could have been exposed to Creutzfeldt-Jakob disease during surgical procedures. About the same time and over the next several years, hospitals in Atlanta
notified patients of similar concerns. Follow Jaimy Lee on Twitter: @MHjlee
