Which type of alert can be configured within Epic Willow?

The correct choice is drug interaction alerts. In Epic Willow, which is designed to support medication management and pharmacy operations, drug interaction alerts are a crucial feature. These alerts ensure that healthcare providers are informed of potential adverse interactions between medications before they are prescribed or administered. This functionality helps enhance patient safety by preventing negative outcomes due to drug interactions.

While the other choices might seem relevant in a broader healthcare context, they do not pertain to the specific capabilities of Epic Willow. Weather alerts are typically outside the scope of electronic health record systems, appointment reminders are more aligned with scheduling systems rather than pharmacy management, and billing notifications focus on administrative processes rather than clinical safety measures related to medication. Hence, drug interaction alerts stand out as a key component in the functionality of Epic Willow, relevant to its goal of promoting safe medication practices.
