Introduction to Emergency Medical Services Notes

Introduction to EMS

  • Best Practices in EMS

    • EMS must strive to embrace best practices when conducting and evaluating research.
    • Aim: Provide high-quality care for patients.

  • Scientific Method Example

    • Example: Hypothesis that bandages control minor external bleeding better than no intervention.
    • Experiment: Conduct a randomized control study.
      • Patients assigned to either 'bandage group' or 'do-nothing group.'
      • Measure and compare the amount of bleeding in both groups.
    • Ethical considerations must be acknowledged.
    • Value of proper experimentation: results should consistently hold up across repetitions, regardless of the experimenter's identity.

  • Peer-Reviewed Research

    • Definition: Research published in medical journals undergoes peer review.
    • Objective: Ensures research methods and results are accurate and maintain high quality.
    • Non-Peer Reviewed Sources
    • EMS magazines often contain articles by EMTs, paramedics, and physicians.
    • Intended to educate and inform, but usually do not present original research or undergo peer review.

  • Significance of Research in EMS

    • Critical for advancing EMS practices.

Special Issues in EMS

  • Human Error in Medicine

    • EMTs are susceptible to making mistakes, which can lead to significant repercussions, including legal actions.
    • Importance of discussing Medical/Legal and Ethical Issues will be addressed later in the text.

  • EMT Training

    • Course will cover local issues, regulations, and administrative matters in EMS.
    • Instructor will provide:
    • Course descriptions
    • Class schedules
    • Certification requirements (physical and mental)
    • Local statutes and regulations

  • Americans with Disabilities Act (ADA)

    • Establishes guidelines to protect the rights of people with disabilities.
    • Advice for Students
    • Inquire with instructors regarding any questions or concerns about ADA compliance.

Research Impact on EMS Practice

  • Historical Use of Oxygen

    • Previous perception: Oxygen was viewed as a 'wonder drug'.
    • Research findings:
    • Excessive oxygen can be harmful to specific patients (e.g., those with heart attacks or strokes).
    • EMTs must administer oxygen and other medications judiciously, tailored to the patient's condition.

  • Challenges to Research in EMS

    • EMTs face unique obstacles due to:
    • Unstable work environments
    • Brief encounters with patients
    • Disjointed and non-centralized data collection
    • Ethical dilemmas in accessing patient consent in emergencies
    • Yet, opportunities exist for meaningful research in prehospital care by upholding research best practices to inform quality care.

  • Research Quality in EMS

    • Distinction between good and poor studies.
    • Promotion of evidence-based practices requires embracing effective research methodologies.

The Scientific Method in Research

  • Method Overview
    • Developed by Galileo, the scientific method unfolds through:
    • General observations
    • Developing a hypothesis (unproven theory)
    • Making predictions based on the hypothesis
    • Testing predictions to affirm or reject the hypothesis.

Medical Direction in EMS

  • Types of Medical Direction

    • Off-line Medical Direction
    • Issued as standing orders allowing EMTs to administer medications/perform procedures without direct communication with a physician.
    • On-line Medical Direction
    • Involves real-time orders from an on-duty physician communicated via radio or phone.

  • Protocols & Procedures

    • Vary between EMS systems and should be accessible on various platforms, such as mobile apps.

EMS Role in Public Health

  • Public Health Overview

    • Defined as the system managing a population's basic health.
    • Efforts include:
    • Prenatal care promotion
    • Injury prevention (especially for children and geriatric patients)
    • Tobacco use reduction campaigns
    • Obesity reduction strategies through improved dietary choices

  • Specific EMS Public Health Initiatives

    • Injury Prevention
    • EMTs identify hazards in geriatric homes (e.g., loose rugs).
    • Run clinics for blood pressure checks and medication presentation for emergency situations.
    • Youth Prevention Programs
    • Involved in car seat clinics, distributing bicycle helmets, etc.
    • Vaccination Programs
    • Training EMS to provide public vaccination clinics.
    • Disease Surveillance
    • EMS as a reporting mechanism for emerging health trends (e.g., flu, opioid overdoses).

Quality Improvement in EMS

  • Role in Quality Improvement (QI)

    • EMTs are accountable for quality in several areas:
    • Documentation quality: Ensuring reports are comprehensive and accurate.
    • Engagement in QI processes: Opportunity to contribute to team reviews.
    • Receiving patient feedback: Seeking comments from patients on care provided.
    • Equipment maintenance: Regular checks and preparedness of equipment.
    • Continuing education: Staying updated with evolving practices and procedures.

  • Definition of Quality Improvement

    • Providing the level of care you would want for loved ones in emergency situations.

Traits of a Good EMT

  • Physical Requirements

    • Good health and physical fitness to perform tasks effectively.
    • Ability to lift and carry loads (up to 125 lbs/57 kg), coordinate movements effectively, and perform basic rescue procedures.
    • Clear eyesight and hearing for patient assessment, scene management, and communication.

  • Personal Attributes

    • Pleasant, sincere, cooperative, resourceful, emotionally stable, neat, and clean.

Understanding EMS Training Levels

  • Levels of Training
    • Emergency Medical Responder (EMR)
    • Primer level for first responders, focusing on immediate care of life-threatening injuries.
    • Emergency Medical Technician (EMT)
    • The minimum standard for ambulance personnel, emphasizing basic medical and trauma care.
    • Advanced Emergency Medical Technician (AEMT)
    • Extends EMT roles with advanced levels of care.
    • Paramedic
    • Highest level, encompassing advanced patient care and decision-making skills.
    • Some states permit registered nurses and physicians to provide advanced care within prehospital settings.

The Role of Emergency Medical Dispatchers (EMD)

  • Importance of EMDs

    • Ensures callers receive immediate assistance and medical instructions.

    • Early access to life-saving care, including CPR and bleeding control.

    • 911 System Statistics

    • Approximately 240 million calls annually; over 80% from mobile devices.

    • Technological Advancements in Dispatch

    • Enhanced 911 technology improves locational accuracy for emergency responses, especially with mobile calls.

Conclusion

  • Future of EMS

    • Emphasis on constant adaptation and improvement in response to new evidence and technologies, ensuring a high standard of care in emergency medical services.

  • Resource Management and Systems Development

    • All systems and resources facilitating emergency responses must be compliant with established guidelines, managed effectively, and continually assessed for improvement.
