Summary
This study developed the ADI 8, a new scale to measure hospitalized patient dependency. The ADI 8 accurately identifies nursing care needs and demonstrates high reliability and discriminative power.
Area of Science:
- Nursing Science
- Patient Care Assessment
- Healthcare Instrumentation
Background:
- Nursing care involves critical evaluation for patient independence and routine medical prescription implementation.
- Accurate assessment of patient dependency is crucial for appropriate nursing evaluations and care planning.
Purpose of the Study:
- To develop and validate a reliable instrument for measuring the dependency levels of hospitalized patients.
- To improve the identification of nursing care needs through a new dependency scale.
Main Methods:
- Development of the eight-rank ADI 8 scale for assessing patient dependency.
- Comparative validation of ADI 8 against the Barthel Index and Swiss Grid (MS).
- Reliability testing using paired observers in blind mode and Kendall statistics.
Main Results:
- The ADI 8 scale demonstrated superior discriminative power for medium dependency levels compared to existing instruments.
- ADI 8 showed a reduced tendency to overestimate patient dependency versus the Barthel Index.
- Kendall statistics confirmed high reliability for ADI 8, with an overall score of .80.
Conclusions:
- The ADI 8 is a valid and reliable tool for assessing hospitalized patient dependency.
- This scale enhances the ability to identify specific patient needs for tailored nursing care.
- ADI 8 offers improved accuracy in dependency assessment, particularly for moderately dependent patients.
