Research Summary

Dr. O’Connor has focused his scholarly work on the interface between primary care and substance abuse. This has included research examining the transfer of substance abuse treatment strategies from “specialty” settings to primary care settings. His publications in this area include studies on the management of opioid withdrawal in primary care settings, opioid maintenance in primary care, and the use of naltrexsone for treating alcohol dependence in primary care patients. He has been active in medical education on substance abuse both nationally and internationally.
