BACKGROUND: OBJECTIVES: STUDY DESIGN: A prospective, comparative evaluation. METHODS: A total of 200 patients from an interventional pain management setting, divided into two groups of 100 consecutive patients receiving either hydrocodone (Group I) or methadone (Group II) were evaluated with urine testing for illicit drug use, and/or misuse or abuse of opioids. Drug testing was carried out by Rapid Drug Screen(R). RESULTS: Results of this study showed that 22% (95% CI, 13% - 30%) of Group I patients receiving hydrocodone used illicit drugs as compared with 24% (95% CI, 15% - 32%) of those in Group II who were receiving methadone. The misuse or abuse of a prescription opioid was seen in 3% (95% CI, 0% - 6%) of the patients in Group I and 12% (95% CI, 5% - 18%) in Group II. In a significant proportion of patients in both groups, the drug prescribed for them was not detected on testing. The combined use of illicit drugs and misuse of prescription drugs was noted in 24% (95% CI, 15% - 32%) in Group I and 33% (95% CI, 23% - 42%) in Group II. CONCLUSIONS:
