Gameplan : 

Gameplan Background Methods Results Application

Origins : 

Origins NHTSA Uniform Prehospital EMS Data Conference - August 1993 Attendees wanted outcome measures Emphasis on non-mortality NHTSA Morbidity Outcomes Workshop - April 1994

NHTSA Workshop: Outcome Measures : 

NHTSA Workshop: Outcome Measures Death Disease Disability Discomfort Dissatisfaction Destitution

NHTSA Workshop: Recommendations : 

NHTSA Workshop: Recommendations 1) Identify priority conditions 2) Improve/standardize risk adjustment 3) Identify outcome measures 4) Support proven evaluation methods 5) Support development of databases 6) Provide info to stakeholders 7) Identify stakeholders/ build support 8) Identify barriers

Priority Conditions:Frequency and Magnitude of EMS Impact : 

Priority Conditions:Frequency and Magnitude of EMS Impact

EMSOP : 

EMSOP Support and facilitate outcomes research Focus on emergent acute care Provide a “blueprint” Provide a “toolbox”

Priority Conditions:Frequency and Magnitude of EMS Impact

Development of Pool of Conditions : 

Development of Pool of Conditions NHTSA Uniform Prehospital EMS Data Elements Amalgam list of illness, injury, signs and symptoms 29 conditions

EMS Frequency DataEMS Data Systems Inc. :

The Next Step : 

The Next Step How to measure the potential impact of EMS intervention on these conditions?

Determining Impact : 

Determining Impact Ask opinions Physicians, Administrators, Providers Consider Relevance of outcome category Potential impact

The Next Step : 

The Next Step Identify risk adjustment measures Identify appropriate outcome measures

“Risk Adjustment” : 

“Risk Adjustment” “…account for pertinent patient characteristics before making inferences about effectiveness or quality of care..” Compare apples to apples

Conceptual Framework : 

Conceptual Framework The Episode of Care

Identifying RAs and Outcome Measures : 

Identifying RAs and Outcome Measures Literature review Panel discussion Previous use in Prehospital or other venues Feasibility Focus on “real world” Also considered research arena Recommendations for evaluation

What Have WeAccomplished? : 

What Have WeAccomplished? Evaluation of methodology Conceptual framework Focus for research and evaluation Priority conditions Importance of non-mortality measures “Toolbox”

Disappointments : 

Disappointments Satisfaction measures Cost measures Pediatric measures (infants, special needs) Data sets

Future Applications : 

Future Applications Acceptance of Priority conditions Tracers Philosophical Issue: Accept importance of non-mortality measure Relieve discomfort vs. save lives

Future Applications:Pain : 

Future Applications:Pain Is pain a substantial problem among prehospital patients? 1999 NHAMCS 52% no pain measure 20% moderate/ severe pain 14% mild 14% none Conservative estimate: 1 in 5 have substantial pain

The Next Step : 

The Next Step Evaluate Feasibility Describe the “epidemiology” Monitor/Modify Researchers: identify/develop/evaluate measures conduct observational research conduct interventional research

Challenges : 

Challenges Access to data Funding Manpower Human use issues Effective dissemination

Summary : 

Summary The “Age of Accountability” Non-mortality measures important EMSOP provides focus and simple tools Many challenges Get to work now
