Medication accuracy and general practitioner referral letters.

Prescriber medication communication is a Quality Use of Medicines barrier. Medication information in General Practice (GP) referral letters to a physician was evaluated. Accuracy of medications taken and drug dose was respectively 63% and 84%, an overall accuracy rate of 58%. Complementary/over-the-counter medication documentation occurred in 26% of the letters. To avoid medical mismanagement, physicians must validate all GP medication lists regardless of their apparent comprehensiveness.
