ObjectiveThe purpose of this study was to determine if the opioid risk tool (ORT) was clinically useful in guiding physician decision making during chronic opioid therapy and to determine whether there were differences between the patient-completed and physician-completed ORT.DesignRetrospective review of prospectively collected data.SettingA single-center tertiary care outpatient pain management center.Patients, ParticipantsOne-hundred twenty-five patients who received chronic opioids as part of their pain therapy.InterventionsPatients receiving care were asked to complete the ORT as part of their initial evaluation. In addition, as part of this study, a pain physician reviewed the information available at the time of the initial evaluation and completed the ORT. Medical records were reviewed for evidence of moderate-to-severe aberrant drug-related behavior (ADRB), according to specified criteria.Main Outcome MeasuresPatient-completed and physician-completed ORT and presence or absence of moderate to severe ADRB.ResultsOf the 125 patients included in this study, physician-completed ORT was available for 125 patients, and a patient-completed ORT was available on 87 of these patients. There was good correlation between the patient-completed and physician-completed ORT (correlation coefficient = 0.61). There were 112 observations of ADRB in 53 of 125 patients (42.4 percent) during the observation period of an average of 7.8 months (range 2-17 months). Of these 53 patients, 32 (60.4 percent) were identified by urine drug screen (UDS) alone, 7 (13.2 percent) were identified by physician observation alone, and 14 (26.4 percent) were identified by both UDS and physician observation. Based on the physician-completed ORT, 41 of 106 (38.7 percent) low risk patients had ADRB, compared to 8 of 14 (57.1 percent) moderate risk, and 4 of 5 (80 percent) high risk patients.ConclusionsNeither the patient-completed nor the physician-completed ORT was strongly predictive of moderate-to-severe ADRB in patients receiving chronic opioid therapy for the treatment of noncancer pain in our pain center.
