Summary • Emergency department visits for adverse events (especially medical/surgical complications) among persons 65+ are increasing • Consumer receipt of verbal counseling regarding medications remains far below the HP 2010 target • EMR and CPOE usage is increasing and has exceeded the HP 2010 targets • Demand is approaching supply for blood donations
