Background:
A comprehensive geriatric assessment (CGA) is a multidimensional assessment that is designed to detect health problems. A barrier to conducting the CGA is the length of time required to complete the entire assessment.
Objective:
To understand what items contained in the instruments that make up the CGA could be compiled to construct an abbreviated CGA (aCGA).
Design/Setting:
A retrospective chart review of patients at the H. Lee Moffitt Cancer Center.
Participants:
Over 500 charts between 1995 and 2001 were reviewed on patients 70 and over.
Measurements:
Item-to-total correlations and Cronbach's alpha coefficient were calculated. Construct validity was assessed using a Pearson's product moment correlation coefficient.
Results:
Fifteen items were compiled to form the aCGA. Cronbach's alpha was 0.65-0.92 on each instrument of the entire CGA compared to 0.70-0.94 on the aCGA. Correlations ranged from 0.84 to 0.96 for the entire CGA and the aCGA.
Conclusion:
An aCGA can be helpful in screening for those seniors who would benefit from the entire CGA.
