Just for completeness this has been resolved here:
Hello, @slubwama I would like to deploy a hospital EMR system for a medical centre which has Reception, Laboratory , Pharmacy and the OPD clinic. Is there a system I could customise? How best can I go about with this? I am seeking your guidance.
@slubwama how do you deal with patient queues that need to be automatically closed for like cases where a patient changed their mind and walked back home without seeing the service provider that they had queued for?
@spkabugo1 this can be dealt with a a scheduled task. Its not yet implemented in the queueing module but a potential ticket
