This. From my limited experience, even with all the systems able to talk HL7, apparently what message segments the system sends, the message segments the system reads etc. are different from system to system. The result is entire subsystems or heavy customizations for redirection, massaging, and transformation of messages. Something to think about systems integration.
Another approach is to buy subsystems from as few vendors as possible (naturally subsystems from one vendor would all talk among themselves very nicely) - but that is obviously not without any repercussions.
I'm a pharmacist based in Singapore working in IT side of things for the pharmacy department in a public hospital here (means: pharmacy system, EMR, inpatient automated system, decision support). Still learning but would be happy to keep in touch.
