The emergency medical services (EMS) system has the potential for a more global public health role to identify unmet needs of older adults. To evaluate the test-retest reliability, the concurrent criterion validity, and the construct validity of prehospital, EMS case finding for depression and cognitive impairment in older adults. Cross-sectional study. Prehospital EMS system and hospital emergency department. EMS providers and community-dwelling older adult (age≥60) patients. Case finding instruments for depression (PHQ-2) and cognitive impairment (Six Item Screener.) The reliability and validity of these instruments. We found moderate test-retest reliability for prehospital application of the PHQ-2 (kappa=0.50) and Six Item Screener (kappa=0.52); fair concurrent criterion validity for depression (kappa=0.36) and slight to fair concurrent criterion validity for cognitive impairment (kappa=0.11–0.23). Construct validity was demonstrated through the Multitrait-Multimethod Matrix. We demonstrated moderate test-retest reliability and construct validity for prehospital case finding by EMS providers for cognitive impairment and depression using these instruments. Slight to fair concurrent criterion validity was found, a result that could be explained by methodological limitations. These findings provide additional support for the concept of using EMS providers to detect older adults at risk for these conditions. Further work is needed to confirm the validity and effectiveness of prehospital screening before such programs are implemented.
