Med 1/2 now replaced by the ICAO standard 'Medevac' and 'Hospital' terminology in Oz. 'Hospital' priority (declared by medical authorities) is only accorded equal priority with normal RPT but 'Medevac' will definitely deliver you higher priority ("... [MEDEVAC] flights shall be granted priority as necessary" according to the book and it does not specify that it needs to be declared by medical authorities). I would have thought declaring 'Medevac' would have been as good as declaring a PAN for the purpose of communicating the level of priority required from ATC for a sick passenger? Do company SOPs provide any guidelines for this situation and what call should be given?
