Within the last two years, many hospitals across Michigan have improved the way that patients get prescription drugs during their hospital stays — improvements that should lead to fewer physician errors and fewer adverse drug reactions, according to results from a national report. The report, called “Preventing Medication Errors in Hospitals,” reviewed data on how many hospitals across the country use newer computerized systems that are fully set up to prevent medication errors — which are the most common type of error to happen in hospitals, according to a news release from the Economic Alliance for Michigan.
