DENVER -- With the recent incident involving a scrub tech with hepatitis C, Rose Medical Center said it is working to make access to dangerous drugs like Fentanyl a lot harder.

But 7NEWS checked other area hospitals and found Rose is a little late in making that move.

Porter Adventist Hospital already requires fingerprints to access drugs and uses tamper evident Fentanyl ampules. The policies were put into effect three years ago but it's one that Rose is just looking to implement now.

Another method of surveillance Porter uses has to do with drug waste.

"At the end of the day the anesthesiologist has to bring everything back to the pharmacy where we test it to make sure it is Fentanyl or any other medication," so that it can't be refilled with saline, said Ryan Stice, Porter's director of pharmacy. "We do that randomly and the staff knows and it's just a way to deter diversion."

University Hospital does not use tamper evident Fentanyl ampules but does use fingerprint machines and checks in drug waste.

Both Porter and University said they're confident in their policies but say they will still be reviewing them because they admit what happened at Rose could still happen at their hospitals because you can't control human behavior and there's always room for improvement.
