Michelle McMahan stole her patients' pain medications so she could take them herself.
Diana Bjorneberg supported her drug habit by tampering with syringes and putting patients at risk for infection.
Catherine Callaway replaced liquid anesthetics with saline, feeding her addiction while leaving patients to suffer.
They are three of the 112 Minnesota nurses who since 2010 are licensed to practice despite having either stolen narcotics on the job, fraudulently obtained prescriptions, or practiced while impaired by drugs or alcohol, a Star Tribune examination of more than 1,000 Minnesota Board of Nursing disciplinary records has found.
Nearly all of those nurses have kept their licenses by taking part in a state program created to protect the public from health professionals who are alcoholics or drug addicts. To avoid further board action, they have to prove they are sober and getting treatment.
Yet records show that nurses have been able to keep practicing while abusing drugs or alcohol, raising questions about whether the program actually works.
Nurses can spend months under state monitoring while missing or failing drug tests, disciplinary records show. If they are kicked out of the program, it can take months more for the Nursing Board to act. Some nurses have been able to use or steal narcotics while enrolled in the program, records show, while others completed the monitoring but later relapsed.
Former nurse Sue Qualick said she stole painkillers from St. Paul's Regions Hospital for a year while under state monitoring. "There should have been a red flag for somebody," Qualick told the Star Tribune. "I don't think I should have gotten away with it for as long as I did."
