Long-term care patient assessment. Evaluation of a methods effect

Area of Science:

• Gerontology
• Nursing Administration
• Health Services Research

Background:

• Patient classification instruments are crucial for resource allocation in long-term care.
• Accurate assessment of patient functional ability is essential for effective nursing time management.
• Existing instruments may have limitations in reflecting patient care needs and rater reliability.

Purpose of the Study:

• To evaluate the influence of functional ability levels in patient classification instruments on explaining nursing time.
• To compare the reliability and explanatory power of different scale configurations.
• To inform the design and application of patient assessment tools in long-term care settings.

Main Methods:

• Evaluation of a patient classification instrument used within the Veterans Administration.
• Analysis of how different functional ability scale levels (e.g., three-level vs. four-level) correlate with nursing time utilization.
• Assessment of inter-rater reliability across different scale designs.

Main Results:

• A three-level scale combining 'supervision' and 'help' required patients explained LPN and nurse's aide personal care time less effectively.
• A four-level scale, or a three-level scale combining 'supervision' and 'independent' patients, demonstrated better explanatory power for nursing time.
• Scale design significantly impacts the ability to explain nursing time and inter-rater reliability.

Conclusions:

• The granularity of functional ability levels in patient classification instruments is critical for accurately explaining nursing time.
• Instrument designers and users should carefully consider scale construction to optimize explanatory power and reliability.
• Findings support the use of more differentiated scales for patient assessment in long-term care.
