Abstract
OBJECTIVE
To develop and test the inter-rater reliability of a coding system for geriatric problems identified through Comprehensive Geriatric Assessment (CGA) of hospitalized older persons, recommendations generated by the assessment, and implementation strategies for these recommendations.
DESIGN
Validation study.
SETTING
A health maintenance organization and a geriatrics academic program.
PARTICIPANTS
A total of 49 hospitalized older persons, who met at least 1 of 13 inclusionary "targeting" criteria, two geriatricians, and one social worker who coded forms.
MEASUREMENTS
Standardized coding of CGA consultation sheets into (1) geriatric problems identified, (2) recommendations, and (3) implementation strategies; inter-rater reliability testing of coding system using two physicians and a social worker.
RESULTS
On average, each assessed patient had 4.8 recommendations. The largest percentages of recommendations were for non-physician referrals (18.2%), advance directives (13.4%), medication adjustments (11.5%), diagnostic evaluation/monitoring (11.5%), and community services (10.9%). The proportions of agreement between raters in coding problems ranged from 0.77 to 0.90, in coding recommendations from 0.69 to 0.86, and in coding implementation strategies from 0.68 to 0.83.
CONCLUSION
A classification system for measuring some components of the process of care of CGA has satisfactory inter-rater reliability, can be adapted for other settings, and may provide valuable insight into determining which components of CGA confer health benefits.
