Electronic decision support can prevent them but only if history of adverse is recorded in structured format. We have conducted a retrospective study 31,531 patients with statins documented notes, as identified natural language processing. The software statin sensitivity 86.5% and precision 91.9%. Only 9020 these had an reaction format. In multivariable analysis strongest predictor documentation utilization EMR functionality that integrated medication list repository (odds ratio 48.6, p < 0.0001). Integration information flow between modules help improve potentially drug events.
