The problem of medication error starts when patients are asked what drug they are taking when they come into the hospital, Schnipper said. "Patients don't know what they are taking. You have got to carry your current accurate medication list in your wallet," he advised.
Since the initial study, error rates have continued to drop as people got used to the system and the "culture" in each hospital changed to accommodate the program, Schnipper said. "Preliminarily, it looks like we are down to half an error per patient," he said.
The Joint Commission on Accreditation of Healthcare Organizations has made medication reconciliation a national priority. Medication reconciliation is identifying the most accurate list of all medications a patient is taking, and using this list to give correct medications for patients anywhere within the health-care system.
Matthew Grissinger, a medication safety analyst at the Institute for Safe Medication Practices, believes the study is a good model for hospitals to follow to help reduce medication errors.
The most important feature of the system was developing a method for taking patient's medication history on admission. "Standardizing the process of who is going to do what in regard to medication reconciliation in hospital admission and discharge is really the biggest challenge organizations have," he said.
In a second report, a team led by Michael D. Murray, chair of the department of pharmaceutical policy and evaluative sciences at the University of North Carolina at Chapel Hill, found that among outpatients with high blood pressure, when pharmacists, doctors and patients communicate, medication errors decrease.
"By working closely with doctors and nurses, pharmacists can help people avoid problems with their medication for chronic diseases like high blood pressure
