The prescriber report card is a new type of report that is emerging among State PDMPs. A typical report card contains a summary of a healthcare provider's personal prescribing history and her/his ranking compared to the "average" prescriber of the same medical specialty. A summary or graphical representation of the prescriber's prescribing history is also included in the report card. The report card may also contain a summary description of patient prescription records, risk status, and other clinically relevant information. The use of these report cards is promoted in this guide as "a promising practice that not only provides an opportunity for self-examination of a prescriber's practice as it pertains to their prescribing of controlled substances, but also provides a more efficient method for reviewing patient prescription histories and associated risk." Depending on the particular PDMP, a report card may be a solicited report requested by the prescriber or sent as an unsolicited report to a prescriber. This technical assistance guide (TAG) presents examples of both types. The information for this guide was compiled from interviews with the PDMP administrators from three States (Arizona, Kentucky, and Ohio). In addition, four physicians were consulted to obtain a prescriber's perspective on the utility of the report card system and what elements should be considered for a model report card.
