Thank you for your post.
All treatment items are displayed in the treatment tab on the patient's record regardless of whether they were completed manually or using the Autocomplete feature.
If you wish to revert an item of treatment back to the active status then, from the Treatment Tab on the patient's record select the item of treatment that you wish to set as active and then click the 'Uncomplete' button at the bottom of the screen.
If the course of treatment has been completed, then the course has to be uncompleted before an item of treatment can be uncompleted.
To do this, from the Treatment tab of the patient's record place a tick against Show Old Plans to display all completed courses of treatment. Select the relevant course in the top panel and then click the 'Uncomplete' button in the centre of the screen. Select the relevant item of treatment in the bottom panel and then click the 'Uncomplete' button at the bottom of the screen.
If this does not resolve your issue then please let me know.
The treatment plans that you are trying to find, are they being entered directly into R4 or are they being imported from another program, for example cerner?
