Validation of a new method for patient classification, the Oulu Patient Classification

Area of Science:

• Nursing Care Intensity Measurement
• Health Services Research
• Patient Classification Systems

Background:

• The Oulu Patient Classification (OPC) system was further developed with weight coefficients and nursing care intensity estimation per nurse.
• Nursing care intensity is measured by points per nurse daily.
• Vasa Central Hospital in Western Finland implemented these developments.

Purpose of the Study:

• To conduct a validity test of the developed Oulu Patient Classification (OPC) system.
• To compare OPC daily patient classifications with a new instrument, PAONCIL.
• To evaluate the concurrent and construct validity of the OPC.

Main Methods:

• A validity test comparing OPC daily patient classifications with the PAONCIL instrument.
• Study conducted across eight wards over 3 months.
• Statistical analysis using simple and multiple linear regression.

Main Results:

• Concurrent validity showed a coefficient of determination of 0.366, indicating a fairly strong association (36.6%).
• Construct validity remained largely intact when patients were categorized by nursing care intensity.
• A clear correlation was found between OPC scores and the six sub-areas of nursing care.

Conclusions:

• The Oulu Patient Classification (OPC) demonstrated fairly adequate validity based on the study.
• The OPC system has a good basis for further research and development in nursing care.
• No other factors independently explained PAONCIL values besides the OPC itself.
