ABSTRACT
Background: Medication errors pose a significant risk to patients, resulting in morbidity, mortality, and unnecessary health care utilization. Pharmacists, using their professional judgment, have an important role as a final check for identifying and resolving these problems. Little is known, however, about pharmacist perspectives and experiences with dispensing or withholding potentially dangerous prescriptions. Objectives: To (a) evaluate the extent to which pharmacists would not dispense a likely harmful prescription which has been confirmed by the prescriber and (b) assess pharmacist attitudes and experiences with dispensing likely harmful prescriptions. Methods: An anonymous, self-administered, 25-item survey was emailed to members of a state pharmacy association and a pharmacy college alumni list. A series of static prescription vignettes (1 reasonable and 4 likely dangerous doses) were presented and asked if they would fill each prescriber-confirmed prescription. Pharmacists also were asked a series of Likert-type, open-ended, multiple choice, and demographic items regarding their professional experiences and role perceptions. Results: There were 497 usable responses. Three of the 4 dangerous prescriptions were withheld by the majority of pharmacists (sumatriptan as the exception). No demographic variable was universally associated with filling dangerous vignette prescriptions; rather, there were vignette-specific differences. The majority of pharmacists reported refusing to fill a potentially harmful prescription during their career. Conclusions: There appears to be meaningful variation in how pharmacists react when presented with likely harmful prescriptions. More research is needed to better understand this role, its determinants, and the potential effects on patient safety.
