For patients admitted while taking chronic outpatient opioids, how do you decide whether to resume their baseline opioid regimen at discharge versus tapering or modifying therapy during hospitalization?  

I'm not sure there's a single right answer here. My only recommendation is for patients who are on chronic outpatient opiates: please talk to their ambulatory clinician before making any significant changes. Their ambulatory doctor knows them over time and can give you advice regarding what's happen...
