The Correction of Product Information in Drug References and Medical Textbooks

The purpose of this project was to correct inaccurate information about Novo Nordisk products in drug references and medical textbooks. Twenty-six commonly used drug references (print or electronic) and 11 medical textbooks were reviewed for accuracy of information for all Novo Nordisk products; errors or omissions were identified in 32 of the 37 references reviewed. Inaccurate drug information most commonly involved product omissions or outdated product information. Letters describing the identified errors and suggested corrections were sent via US mail or e-mail to the authors, editors, or publishers. Within 18 months of sending the letters, 21 of the 32 references reviewed had published updated editions, which were then reviewed again to assess the impact of the communication. A total of 190 of 448 identified errors (42%) had been corrected.
