Say What?

While catching up on my journal reading, trying to lower the stack of old American Family Physicans in my office, I came across this gem of a sentence in the abstract of Cirrhosis and Chronic Liver Failure:

"Unnecessary medications and surgical procedures should be avoided in patients with cirrhosis."

Got it. Reserve unnecessary medications for hypertensives with good blood pressure control and diabetics with A1Cs under 7%. Unnecessary surgical procedures may be performed between exacerbations of COPD. Both should be avoided in liver disease.

What were they thinking?
