Services to patients who are not admitted and who receive treatment that was either unplanned or carried out in designated emergency departments within a hospital. Unplanned patients are patients who have not been booked into the hospital before receiving treatment. In general it would be expected that most patients would receive surgical or medical treatment. However, where patients receive other types of treatment that are provided in emergency departments these are to be included. The exceptions are for dialysis and endoscopy and related procedures which have been recommended for separate counting.
This metadata item identifies types of services provided to non-admitted patients in different institutional ways in different systems. It is not a summary casemix classification.
A patient who first contacts the hospital and receives non-admitted care, for example through emergency departments, and is subsequently admitted, should have both components of care enumerated separately. Where possible, non-admitted occasions of service that are provided to patients who are subsequently admitted should be identified as a subset of the total occasions of service. The list of Type of non-admitted patient care categories was to be developed using typical functional units or cost centres within existing institutions. These would include designated wards or departments and specialised clinics. Although the current statistical/financial returns submitted to the various health authorities by their hospitals do not provide a minimum subset, an effort has been made to define the categories in respect to those areas commonly collected. Many functional units provide services to both admitted patients and non-admitted patients, for example pathology. Only occasions of service for non-admitted patients should be included in this section.
The definition does not distinguish case complexity for non-admitted patients.
For example, an occasion of service could vary in complexity from a simple urine glucose test to a complete biochemical analysis of all body fluids. Ideally, average case complexity values would be available for the various categories of non-admitted patients in the same way that average diagnosis related group weighted separations are becoming available for acute admitted patients. However, such measures would require the development of patient record databases for non-admitted patients. This does not imply an inadequacy in definition.
For admitted patients the concept of a separation is widely accepted. Separations can vary between admission for overnight observation to open heart surgery. The issue of case complexity for both admitted and non-admitted patients is a separate issue and beyond the scope of the proposed summary establishment-level activity data.
