Screening and Interventions in an Acute Care Setting

Completed

Conditions: Depression
Medication Administered in Error
Cognitive Impairment

Registration Number: NCT00545155

Lead Sponsor: University of Rochester

Brief Summary: The purpose of this study is to: 1) evaluate the reliability and validity of EMS screening for depression and cognitive impairment and 2) to develop a pilot ED intervention program to address the needs of older adults found to be at risk for depression and cognitive impairment.

Detailed Description: Many older adults (age over 64) have undetected health problems and lack basic prevention measures. Failure to identify and treat these conditions can lead to unnecessary morbidity and mortality and a decreased quality of life. Traditional screening and intervention programs, usually based in primary care providers' offices, have been insufficient, particularly in medically underserved populations. Alternate sites for screening and intervention have begun to receive attention and may hold promise.

The emergency medical services (EMS) system is a unique, community-wide system that can be used to perform in-home evaluations to uniformly screen large numbers of vulnerable older adults during emergency responses. The emergency department (ED) is the entry point for access to medical and social services for many patients. Recent programs have used the EMS system to screen patients or the ED to screen and intervene with mixed results, but little has been done to rigorously evaluate an integrated program of EMS screening that leads to focused ED interventions that promote the health of older adults. This proposed project builds upon the principal investigator's preliminary work and unique resources in Rochester, NY to develop and evaluate a program of EMS screening and ED interventions to help community-dwelling older adults with unmet needs. Specifically, this study aims to:

1. Implement an EMS screening program to identify community-dwelling older adults' unmet needs during emergency responses, identifying patients with needs related to depression and dementia.

2. Evaluate the test-retest reliability and concurrent criterion validity of EMS screening for depression and cognitive impairment.

3. Develop and refine an EMS and ED intervention program that addresses the needs of older adults found by EMS to be at risk for depression and cognitive impairment.

Upon completion, this study will have demonstrated the reliability and validity of EMS screening for these conditions and will have proposed an EMS and ED based intervention program template that can be applied to these and a wider range of geriatric disorders.

Primary Outcome Measures

Name	Time	Method
Proportion of Subjects Cognitively Impaired in Emergency Medical Services (EMS)	Upon testing by EMS.	Through testing using the Six Item Screener, this measure indicates the proportion of individuals cognitively impaired when tested by EMS personnel.
Proportion of Subjects Cognitively Impaired in the ED	Within 2 hours of testing by EMS	Through testing using the Mini-Cog, this measure indicates the proportion of individuals cognitively impaired when tested by study personnel.
Concurrent Criterion Validity of PHQ-2	2 hours	This is the PHQ-2, a test for depression (scoring=yes or no) as compared to the PHQ-9, a test for depression (scoring=yes or no), looking at the presence of depression. This is concurrent criterion testing (two different instruments, neither being a gold standard) rather than the previous test-retest reliability testing (testing the same instrument twice).
Proportion of Subjects Depressed in the ED	Within 2 hours of EMS testing	Through testing using the PHQ-9, this measure indicates the proportion of individuals depressed when tested by study staff in the ED.
Proportion of Subjects Cognitively Impaired in the Emergency Department (ED)	Within 2 hours of testing by EMS.	Through testing using the Six Item Screener, this measure indicates the proportion of individuals cognitively impaired when tested by study personnel in the ED.
Test-Retest Reliability of Six Item Screener Screening	2 hours	The Six Item Screener test for cognitive impairment (answer=yes or no)as performed by EMS personnel and study personnel.
Proportion of Subjects Depressed in EMS.	Upon testing by EMS.	Through testing using the Patient Health Questionnaire-2 (PHQ-2), this measure indicates the proportion of individuals depressed when tested by EMS personnel
Concurrent Criterion Validity of Six Item Screener Screening	2 hours	This is the Six Item Screener test for cognitive impairment (scoring=yes or no), as compared to performing the Mini-Cog for cognitive impairment (scoring=yes or no) on patients immediately afterwards. This is concurrent criterion testing (two different instruments, neither being a gold standard) rather than the previous test-retest reliability testing (testing the same instrument twice).
Test-Retest Reliability Testing of PHQ-2 Screening	2 hours	The test for depression, using the PHQ-2, with scoring yes or no.
