Quantifying drug-seeking behavior: a case control study.

BACKGROUND: Drug-seeking behavior (DSB) is common in the Emergency Department (ED), yet the literature describing DSB in the ED consists predominantly of anecdotal evidence. STUDY OBJECTIVES: To perform a case-control study examining the relative frequency of DSB in suspected drug-seeking patients as compared to all ED patients. METHODS: We performed a retrospective chart review of 152 drug-seeking patients and of age- and gender-matched controls, noting which of the following behaviors were exhibited during a 1-year period: reporting a non-narcotic allergy, requesting addictive medications by name, requesting a medication refill, reporting lost or stolen medication, three or more ED visits complaining of pain in different body parts, reporting 10 out of 10 pain, reporting > 10 out of 10 pain, three or more ED visits within 7 days, reporting being out of medication, requesting medications parenterally, and presenting with a chief complaint of headache, back pain, or dental pain. RESULTS: The odds ratios for each studied behavior being used by drug seeking patients as compared to controls were: non-narcotic allergy: 3.4, medication by name: 26.3, medication refill: 19.2, lost or stolen medication: 14.1, three or more pain related visits in different parts of the body: 29.3, 10 out of 10 pain: 13.9, three visits in 7 days: 30.8, out of medication: 26.9, headache: 10.9, back pain: 13.6, and dental pain: 6.3. Zero patients in the control group complained of greater than 10-out-of-10 pain or requested medication parenterally, resulting in a calculated odds ratio of infinity for these two behaviors. CONCLUSIONS: Requesting parenteral medication and reporting greater than ten out of ten pain were most predictive of drug-seeking, while reporting a non-narcotic allergy was less predictive of drug-seeking than other behaviors.

Emergency department frequent user: pilot study of intensive case management to reduce visits and computed tomography.

OBJECTIVE: Emergency department (ED) frequent users account for a large number of annual ED visits and often receive radiological studies as a part of their evaluation. We report a pilot study of a case management program for ED frequent users to reduce ED usage and radiation exposure. METHODS: This observational retrospective study was performed at a community hospital ED. Between May 2006 and April 2008, 96 patients were enrolled in a case management program and were followed through November 2008. The case management program consisted of a multi-disciplinary team of physicians, nurses, social services and specialists in pain management and behavioral health. Patients were enrolled if they had five or more visits to the ED in the previous month, if a concern about a patient's ED use was raised by staff, or if they were identified by the California prescription monitoring program. Case management addressed specific patient issues and assisted with receiving consistent outpatient care. The number of ED visits per patient and the number of radiological studies at each of these visits was recorded. When reviewing data for analysis, we used the number of total images in all computed tomography (CT) scans during the given time period. RESULTS: In the six months prior to enrollment, patients averaged 2.3 ED visits per patient per month. In the six months after enrollment, patients averaged 0.6 ED visits per patient per month (P<0.0001), and all visits after enrollment up to November 2008 averaged 0.4 visits per patient per month (P<0.0001). In the six months prior to enrollment, these patients averaged 25.6 CT images per patient per month. In the six months after enrollment, patients averaged 10.2 CT images per patient per month (P=0.001), and all CT images after enrollment up to November 2008 averaged 8.1 CT images per patient per month (P=0.0001). This represents a decrease in ED use by 83% and a decrease in radiation exposure by 67%. CONCLUSION: Case management can significantly reduce ED use by frequent users, and can also decrease radiation exposure from diagnostic imaging.
