Answer: Opioid withdrawal results from opioid abstinence in patients who are physically dependent on opioids. Assessment of opioid withdrawal can be useful in making the diagnosis of physical dependence and in making decisions regarding initiation and/or titration of medications. A number of scales have been developed for the assessment of opioid withdrawal.
These include the Objective Opioid Withdrawal Scale (OOWS), the Subjective Opioid Withdrawal Scale (SOWS) (Handelsman, Cochrane, Aronson, et al., 1987), the Short Opioid Withdrawal Scale (SOWS) (Gossop, 1990), and the Clinical Opioid Withdrawal Scale (COWS) (Wesson and Ling, 2003).
The OOWS and SOWS (Handelsman et al., 1987) are available at: www.aodgp.gov.au/resourcekit/b4/handout6_opioids.pdf (39KB).
The COWS is available at: www.pcssmentor.org/pcss/resources_clinicaltools.php (39KB).
