For buyers contracting authority
Pick 48814300 when the contract is for the operating-theatre software and the integration around it: surgical scheduling, anaesthesia records, and the workflow that drives an integrated operating room. The line that trips contracting authorities is the parent. Medical information systems (48814000) is the right code for a broad clinical-systems procurement, while 48814300 is scoped to the theatre slice of it.
The siblings draw the other boundaries. Patient-administration system (48814200) handles admissions and bed management rather than the surgical suite, and Clinical information system (48814400) is the general clinical record across the hospital. Reserve 48814300 for the operating theatre specifically.
Where a single contract bundles the theatre system with operating-room hardware and cabling, set the primary CPV code by the dominant deliverable. If the surgical management system is the main purchase, this code fits even when the integration and equipment carry much of the value.
