Patterns in nursing home medication errors: disproportionality analysis as a novel method to identify quality improvement opportunities.

Hansen RA, Cornell PY, Ryan PB, et al. Pharmacoepidemiology and drug safety. 2010;19:1087-94.

This study applied a novel analytic tool to identify rates and patterns of medication error reporting. For example, warfarin was disproportionately co-reported with communication errors just as oxycodone and morphine were with name confusion.
