When a nurse or other healthcare provider enters a new medication order into the EHR, the CDSS checks the patient's current medication list. If the new medication is similar to an existing one, an alert is generated. The alert typically includes: 1. Notification: A message that duplicate therapy has been identified. 2. Details: Information about the medications involved. 3. Recommendations: Suggestions on how to resolve the issue, such as discontinuing one of the medications.
