Medication mistakes are common. A recent study by Amanda Mixon following discharge from the hospital pegs the error rate at an astounding 50%. The study focused on whether instructions given to patients at the time of discharge from the hospital matched what the patient later took at home.
The study is biased by assuming all the errors are caused by patients — not the providers. The authors point to patient problems of low health literacy and a poor facility with numbers. Illegible instructions, poor communication skills, excessive complexity of medical regimens, conflicting instructions, and giving verbal instructions to the wrong person are all provider or institutional issues.
Even a simple phone call after discharge might have cleared up patient confusion — perhaps the study would have been better with a phone call and no phone call comparison.
The article conclusion is to apply more effort to find those high risk patients. Another conclusion would be to find those high risk hospitals having difficulty telling patients what drugs to take. The study was done at a VA facility affiliated with Vanderbilt — a good place to start the search.
