BACKGROUND: Prescription @entity734 is a serious health concern and is considered a nationwide epidemic. @entity1 often fail or refuse to disclose the use of controlled substances, leaving prescribers and pharmacies unaware of the potential for harmful drug interactions and risk of @entity1445 . @entity146 @entity1 are especially vulnerable to controlled substance misuse. OBJECTIVES: To determine hazardous patterns of prescription drug use among @entity146 outpatients and to raise awareness about the importance of reviewing information provided by prescription drug monitoring programs (PDMPs). METHODS: The medical records of 150 @entity1 attending the Adult Outpatient @entity146 Clinic at the Los Angeles County+University of Southern California (LAC+USC) Medical Center from July 2012 through May 2013 were reviewed. @entity1 activity reports were generated from California's PDMP. Nondisclosure of controlled substance use was identified by a discrepancy between @entity1 reporting of prescriptions according to the medical records and PDMP reports. A "pattern suggestive of @entity734 " was defined as having one or more of the following: within-class prescriptions from multiple providers and/or within-class early refills or within-class overlapping prescriptions picked up within 10 days of each other. RESULTS: Of the 150 @entity1 , 113 were found in California's PDMP database. Of these 113 @entity1 , 81 had obtained 111 prescriptions for controlled substances in the past 12 months. Of these 111 prescriptions, 52 (47%) were not disclosed to the primary psychiatrist, of which 14 (27%) revealed patterns consistent with @entity734 . CONCLUSIONS: Reviewing PDMP databases before prescribing controlled substances should be considered a standard prescribing practice to prevent abuse, diversion, and adverse medical outcomes.
