Abstract (Summary)

Purpose: Drug-drug interactions (DDIs) place a burden on our nation and cause potential harm to patients. Awareness of potential DDIs is essential for safe prescribing. Nurse practitioners (NP) have prescriptive authority throughout the nation, however, little is known about NP prescribing habits. The purpose of this study was to identify NPs' demographic and practice characteristics, DDI knowledge and factors that influence this knowledge.

Data Sources: A survey was administered to NP prescribers recruited from a national conference. Data was collected on demographics, practice and technological characteristics, and perceptions and knowledge of DDIs.

Conclusions: Data from 305 questionnaires were analyzed. NPs correctly classified 31% of drug pairs. Nitroglycerin and Sildenafil (drug combination to avoid) was classified correctly by the most respondents (90.8%, n = 305); Warfarin and Gemfibrozil (drug combination to usually avoid) the fewest 15.7% (n = 302). A positive correlation was found between NPs in acute care hospital settings and DDI knowledge, indicating higher knowledge scores. Neither hierarchical linear regression model was significant at predicting NPs' DDI knowledge.

Implications for Practice: Continuing education needs to be targeted to enhance NPs knowledge of potential clinically significant DDIs. The increased recognition of potential DDIs among NPs will enhance patient safety.
