A patient can be registered with QACT for one or more protocols. Protocols can be therapeutic, ancillary, or ancillary-therapeutic; Order Entry chemotherapy orders include only therapeutic or ancillary-therapeutic.
A patient can be registered to one therapeutic protocol and one or more ancillary-therapeutic protocols. You must choose which protocol to use every time you write chemotherapy.
If the patient is registered to one or more ancillary-therapeutic protocols but no therapeutic protocol, you have the option to order from a regimen of your choice, or from one of the registered ancillary-therapeutic protocols.
A patient can be registered to only one therapeutic protocol. Generally, patients on therapeutic protocols cannot be placed on a standard regimen unless the patient is unenrolled from the protocol first. The exception to this is when the therapeutic protocol has been specifically defined to allow ordering from a standard regimen. In this case, you must choose which to use every time you write chemotherapy.
You can order from any or all of the treatments allowed by going through the chemo ordering process separately for each. That is, Write>Chemo, then select a protocol or regimen when prompted, and complete the orders; then Write>Chemo again, selecting a different option.
Once you write orders from particular regimen, it will come up automatically whenever you choose the regimen option.
