Vol 61. July 3rd, 2012. Centers for Disease Control and Prevention 1947: FDA approves for treating substance abuse & pain Background: In the US, doctors prescribe drugs to treat any condition they see fit, even if it is not ap- proved by the Food and Drug Administration (FDA) for that condition. These uses are considered “off- label" and make up over 20% of all prescriptions in the US. We collected over 3.7 million records of patient prescription data and associated medical conditions from 14 different Medical Expenditure Panel Surveys* over the period from 1996-2009. We processed, aggregated and linked this data across multiple years, patients and drug name equivalents, applying textual analysis and other filtering methods as appropriate, to obtain a sample large enough to analyze for off-label drug use by three-digit and top-level ICD-9 medical condition codes. The percentages provided reflect the minimum and maximum share of surveyed prescription cases within a span of one year that were for off-label conditions. The three drug-use timelines highlighted here were chosen based on recent publications and interest for medical professionals. However, our aggre- gated dataset provides easy access to analagous analyses by condition codes for over 2,000 medications. To make the above visualizations accessible to the lay person, we coded the reported three-digit ICD-9 condition codes for Metoprolol, Cymbalta and Methadone into approved and off-label subcategories with the help of a medical professional. The Los Angeles Times, Forbes Magazine, the Veterans Administration, physicians writing to the New England Journal of Medicine, and many other medical organizations have each made calls for better measurement and understanding of off-label drug use in the last year. Each of these calls comes as a direct result of reported increases in morbidity and mortality from non-approved uses of drugs in the US. Our work provides the first library we are aware of with estimates of off-label drug use in the US for a large number of (ie. greater than 10) medications. * available at 9661 Z66I 1998 1997 . 6661 0007 2001 8661 2002 666I 2003 100z 2003 0007 2004 2005 2004 9007 ZO07 2008 2005 6007 LO07 2008 9007
