Medication errors that occurred in New Hampshire community pharmacy settings were included; those that occurred in institutional pharmacy settings were excluded. Information that was extracted from the QRER for the purposes of this study included date, time and description of the medication error, type of error (incorrect dose/incorrect drug/incorrect directions, and incorrect quantity/refills), environmental issues, staffing details, number of prescriptions filled on the day of the event, and the stage of prescription filling where the error occurred. The stages of prescription filling were divided into 6 stages as described in Table 1. The SPSS statistics program was used for data entry and descriptive analysis. Institutional review board approval was not sought for this study due to minimal risk to humans and de-identified data. A total of 68 medication errors were identified during the February 1, 2007, to July 31, 2012, time period. Time between error occurrence and reporting was 1 month 29% and 2 months 26%. Seventy-nine percent of the prescription errors occurred when processing a new prescription; 17% involved prescription refills . The remainder of the errors involved a prescription transfer, and 1 error did not include information as to when the error occurred. A total of 51% of the errors occurred in stage 4 (the pharmacist’s final check) of the prescription processing . This stage included errors that were processed by a pharmacy technician in the data entry phase and errors that were not detected by the on-duty pharmacist. Twenty-six percent of errors occurred during stage 2 (data entry). Among the errors that occurred in this stage, 73% of the data entry was performed by pharmacy technicians, 15% by pharmacists, and 6% by pharmacy interns. In 6%, the person who performed data entry was not identified by the QRERs.
