changing message priority

[Kevin Crist]

Are we able to change the message priority in CL, guessing maybe in tcl? Our midnight maintence shoots out hundreds of discharges at night and if a patient comes in that A04 gets caught behind them. Is there a way to shoot that to the front of the line?

Of course you can change the priority of any message.  The range is 4096-8192.  Default is 5120

For example msgmetaset $mh PRIORITY 8192

From the docs:  PRIORITY

Used to give special treatment to a message. Each message is placed in an engine queue according to its priority. Higher priority messages are placed nearer to the head of each queue than messages of lower priority. Among messages of the same priority, a FIFO queue ordering is maintained

This is how the disposition of PROTO works. It puts the message back on the queue with a priority of 8192 to make sure it is sent first

With that said if the messages come in at different times there is no guarantee one will be delivered before the other.  Note it only applies to messages in the same queue

We have some code like this on our Epic ADT interface:

Code:

            # set batch messages to lower priority
            if { [hl7::get_field hl7 MSH.3] eq “AS_AFTER_EOD” ||
                 [hl7::get_field hl7 MSH.8] eq “REGBATCH” } {
                msgmetaset $mh PRIORITY 4999
            }
