Abstract
OBJECTIVES: To describe associations between resident level of training, timing of medication orders, and the types of inpatient medication ordering errors made by internal medicine residents.
METHODS: This study reviewed all inpatient medication orders placed by internal medicine residents at a tertiary care academic medical center from July 2011 to June 2015. Medication order errors were measured by pharmacists' reporting of an error via the electronic medical record during real-time surveillance of orders. Multivariable regression models were constructed to assess associations between resident training level (postgraduate year [PGY]), medication order timing (time of day and month of year), and rates of medication ordering errors.
RESULTS: Of 1,772,462 medication orders placed by 335 residents, 68,545 (3.9%) triggered a pharmacist intervention in the electronic medical record. Overall and for each PGY level, renal dose monitoring/adjustment was the most common order error (40%). Ordering errors were less frequent during the night and transition periods versus daytime (adjusted odds ratio [aOR] 0.93, 95% confidence interval [CI] 0.91-0.96, and aOR 0.93, 95% CI 0.90-0.95, respectively). Errors were more common in July and August compared with other months (aOR 1.05, 95% CI 1.01-1.09). Compared with PGY2 residents, both PGY1 (aOR 1.06, 95% CI 1.03-1.10), and PGY3 residents (aOR 1.07, 95% CI, 1.03-1.10) were more likely to make medication ordering errors. Throughout the course of the academic year, the odds of a medication ordering error decreased by 16% (aOR 0.84, 95% CI 0.80-0.89).
CONCLUSIONS: Despite electronic medical records, medication ordering errors by trainees remain common. Additional supervision and resident education regarding medication orders may be necessary.
