Variant 3: Vitalink medication scheme changes

Image Modified

Situation / Action	Information
1	OPTIONAL: Support staff starts preparation of the ambulant visit (eg. for staff meeting or oncology visit of the patient) The home medication section of the EHR holds version 1 of the medication scheme
2	The EPD requests the latest version of the Vitalink medication scheme. This action can be done manually by a user action, but is preferably done automatically. Vitalink responds with the same version that is already present in the EPD. The EHR and Vitalink medication scheme are in sync.
3	OPTIONAL: Home Medication in the EHR can be updated in the combined overview during the preparation for the ambulant visit to version 1'.
4	OPTIONAL: Preparing of ambulant visit stops. The EHR holds now version 1'.
5	Start ambulant visit.
6	In the meantime, a new medication scheme was uploaded to Vitalink by another Caregiver. The Vitalink medication scheme is now Version 2.
7	End ambulant visit. The caregiver made changes to the home medication in the EHR. The EHR holds now Version 1".
8	The Home medication of the EHR is exported to Vitalink. The export failed because the version of the medication scheme in Vitalink is more recent than the one in the EHR.
9	Since the EHR holds the master medication scheme version V1", the EHR has to provide an interface (= combined overview) in order to show medication changes between Version 1 and Version 2 of the Vitalink medication scheme and the home medication of the EHR Version 1". The caregiver can validate/reject changes. We recommend to show a notification that there is newer version of the medication scheme on Vitalink.
10	The caregiver can validate/reject changes. The EHR holds now version 2'.
11	The home medication of the EHR is exported to Vitalink. The Vitalink medication scheme now becomes Version 3.
12	Vitalink sends the updated identification code for each medication (URI's) back to the EHR. The EHR requests Version 3 of the medication scheme from Vitalink to update the version and URI's in the EHR.
13	The EHR holds now Version 3. The EHR and Vitalink medication scheme are in sync.

Note

If the Vitalink medication scheme changes during the preparation of the ambulant visit and the person responsible notices,

he/she can download the new version of the medication scheme and take the needed actions (see Variant 2: Home Medication EHR is outdated vs. Vitalink medication scheme Step 2 - 4).

2. Admission

A hospital admission is the moment when a patient is taken being admitted to the care of the hospital. It means the hospital is in charge of the care of this patient. This admission can be only for a couple of hours (policlinical, day clinic, etc.) or for several days, weeks, months and thus include an overnight stay. There are also different types of hospital admission: the admission can be planned e.g. for a surgery or can be an unplanned (urgent) admission e.g. in case of a car accident.

NOTION1 ! EHR information in this section always holds the HOME MEDICATION and ADMISSION MEDICATION.

NOTION2 ! Medication during admission is never uploaded to Vitalink.

Basic flow: Home Medication EHR is already in sync with Vitalink
