The proportion of procedures performed via open, laparoscopic or converted surgery were examined in relation to patient age, sex, year of diagnosis, modified Dukes' stage of disease at diagnosis, tumour location, IMD category, operation type and Charlson co-morbidity score.
They also classified the adverse events into five categories: care, operation, medication, intensive care (IC) and other.
For guiding the design and management of the operations, categories for similar operations can be defined.
These nine categories of operations can be formalized using < operator, inputs, output, parameters, constraints> tuples.
It is getting harder and harder: a Category Two operation costs little short of seven figures annually – that is a commitment beyond most below the Championship and some in it.
For purposes of convenience they are gathered into two categories: those operations which contribute to maintaining the museum as an organization (e.g., administration, management, funding, inter-museum cooperation) and those activities which are most commonly considered to be typical of museums (e.g., collection, preservation, cataloging, exhibition).
The BBS program was aimed at reducing unsafe behavior in nine categories: lifting operations, excavation, working at height, work platform & access, manual handling, hot work (welding/gas cutting), plant & equipment, traffic management, and personal protective equipment (PPE).
The third broad category is operation and functional gaps.
The three digit codes identify broad categories of operations e.g. C18 = correction of ptosis of eyelid.
