2 Objectives Understand research steps Understand research steps Types of research Types of research Understand the need for research in EMS Understand the need for research in EMS Role of provider in research Role of provider in research

3 What is research? Research is learning, seeking the truth Research is learning, seeking the truth We learn and gain experience every day. We learn and gain experience every day. Research is observational or experience Research is observational or experience Anecdotal experience Anecdotal experience Systematic observation Systematic observation Hypothesis testing Hypothesis testing

4 What is evidence based medicine? Aims to apply evidence gained from the scientific method to certain parts of medicine Aims to apply evidence gained from the scientific method to certain parts of medicine Evaluates: Evaluates: Quality of evidence Quality of evidence Risk/benefit of treatment Risk/benefit of treatment Uses current best evidence to guide care Uses current best evidence to guide care

5 IOM recommends: Separate institute of emergency medicine research needed Separate institute of emergency medicine research needed The Future of Emergency Care in the US: The Institute of Medicine Subcommittee on Prehospital Emergency Medical Services, (Ann. Emerg. Med. 2006;48:126-130) The Future of Emergency Care in the US: The Institute of Medicine Subcommittee on Prehospital Emergency Medical Services, (Ann. Emerg. Med. 2006;48:126-130) Challenge for EMS is to measure outcomes.

27 Let’s take a closer look Significant research in EMS

28 Research: General Principles and Emergency Medicine Application John B. McCabe, MD, FACEP

Auto-transfuse 2 units of blood Auto-transfuse 2 units of blood Increase PVR Increase PVR Raise BP Raise BP Stabilize pelvic fractures Stabilize pelvic fractures Control surface bleeding Control surface bleeding Widely used in 1980’s-1990’s Widely used in 1980’s-1990’s “What happened???”

32 What happened… STUDY: Randomized trial of pneumatic antishock garments in the prehospital management of penetrating abdominal injuries STUDY: Randomized trial of pneumatic antishock garments in the prehospital management of penetrating abdominal injuries MDWilliam H Bickell*, MDPaul E Pepe †, ‡,, MDMark L Bailey*, MDCharles H Wyatt* and MDKenneth L Mattox* *Department of Surgery, Baylor College of Medicine, Ben Taub General Hospital, Houston, Texas, USA †Department of Medicine, Baylor College of Medicine, Ben Taub General Hospital, Houston, Texas, USA ‡City of Houston Fire Department Emergency Medical Services, Houston, Texas, USA MDWilliam H Bickell*, MDPaul E Pepe †, ‡,, MDMark L Bailey*, MDCharles H Wyatt* and MDKenneth L Mattox* *Department of Surgery, Baylor College of Medicine, Ben Taub General Hospital, Houston, Texas, USA †Department of Medicine, Baylor College of Medicine, Ben Taub General Hospital, Houston, Texas, USA ‡City of Houston Fire Department Emergency Medical Services, Houston, Texas, USA* †‡ * †‡ *

33 Randomized Study Alternate day randomization (control, N=104, MAST, N = 97) Alternate day randomization (control, N=104, MAST, N = 97) The results demonstrated no significant difference in the survival rates of the control and PASG treatment groups (81 of 104 vs 67 of 97). The results demonstrated no significant difference in the survival rates of the control and PASG treatment groups (81 of 104 vs 67 of 97). “ From these data we conclude that, contrary to previous claims, the PASG provides no significant advantage in improving survival in the urban prehospital management of penetrating abdominal injuries. “ “ From these data we conclude that, contrary to previous claims, the PASG provides no significant advantage in improving survival in the urban prehospital management of penetrating abdominal injuries. “

40 Occupational injuries among EMS personnel McGuire, Hunting, Guidotti, Smith Prehospital Emergency Care 2005;9: 405-411

41 Objective Describe the epidemiology of occupational injuries among EMS personnel, calculate injury rates, and compare findings with other occupational groups. Describe the epidemiology of occupational injuries among EMS personnel, calculate injury rates, and compare findings with other occupational groups. EMS Providers treat 22 million patents per year, little known about our injuries EMS Providers treat 22 million patents per year, little known about our injuries

42 Methods Retrospective review of injury records kept by two urban agencies Retrospective review of injury records kept by two urban agencies 617 cases over 3 years 617 cases over 3 years Injury rate was 34.6 per 100 employees Injury rate was 34.6 per 100 employees Most often sprains, strains and tears Most often sprains, strains and tears Back most frequent Back most frequent 277 cases resulted in lost days from work 277 cases resulted in lost days from work

43 Conclusions Injuries greater for EMS than any other industry in 2000 according to DOL statistics Injuries greater for EMS than any other industry in 2000 according to DOL statistics Recommended funding and further research are critical to define problem and prevent injuries Recommended funding and further research are critical to define problem and prevent injuries

45 Emerging topics Intubation by paramedics Intubation by paramedics Pain management Pain management EMS Skill retention EMS Skill retention System design System design Clinical interventions Clinical interventions

46 Where to start? Descriptive study- what are we doing for our community/school? Descriptive study- what are we doing for our community/school? Where are we making a difference? Where are we making a difference? Pain management Pain management Injury prevention Injury prevention Reduced response time Reduced response time Reduced health care costs Reduced health care costs

47 Research starts with a question and a desire to learn the truth.

48 We know EMS makes a difference, let’s prove it!!
