The need for more effective communication between patient and health care provider has been stressed by many researchers as one means of increasing health regimen compliance. This study measures and analyzes patient-physician communication about prescribed drug therapy. It is reported that approximately 62% of the patients queried said that they were given directions for use of their medications, but less than 59% of this group correctly communicated the directions to the pharmacist. It is concluded that the number of prescriptions written and the status of the patient (Medicaid versus non-Medicaid) affects communication. The role of the pharmacist in patient education is stressed.
