If you haven't already, select the patient and start the chemo order session. See Ordering Chemotherapy.
At the prompt to Continue, Discontinue, Edit, or Cancel (triggered because the patient has active chemo orders), to automatically discontinue the existing orders and write new orders, click D/C Existing (ALT+ D ).
This option is not available for BWH Ambulatory Infusion units.
The discontinued orders are listed as part of the session when you finish ordering.
Write the orders to replace those you are discontinuing. See Ordering Chemotherapy.
