 We will develop a series of clinical alerts in CIS, Baystates computerized provider order entry system, to reduce the use of potentially inappropriate medications among hospitalized elders. We will randomize providers to electronic alerts or usual care. Whenever a provider randomized to alerts attempts to place an order for a high-risk medication on the Beers list and the intended recipient is over 65 years of age, a synchronous alert i.e. a pop-up will inform the physician about the risks associated with the medication and will propose safer alternatives.
