Study Notes

Scientific Method

  • Science is defined as knowledge gained through study or practice.
  • Research is the systematic study to discover or establish facts and principles.
  • EMS uses research to understand how EMS works.
  • EMS is a blend of science (knowledge) and art (application).
  • The scientific method aims to create an accurate, reliable, and consistent representation of the world.

Steps of the Scientific Method

  • Observe and ask questions: Begin by observing something and formulating a question.
  • Conduct research: Gather background information through research (internet, databases like PubMed).
  • Construct a hypothesis: Propose a testable statement to answer the original question.
  • Test the hypothesis by experimentation: Design a controlled experiment to verify the hypothesis.
  • Analyze results and draw conclusions: Evaluate the results and decide if the hypothesis is supported or refuted.
  • Revise the hypothesis (if needed): Adjust the hypothesis based on the findings.
  • Report results: Share findings, even if the hypothesis is refuted, through publications (peer-reviewed journals).

Iterative Process

  • The scientific method is iterative; adjustments and repeats are common during research.

Validity of Full Moon Myths

  • Myth: Increased emergencies (EMS calls, psychiatric episodes, childbirth) during full moons.

  • Research Findings: Numerous studies (e.g., New Jersey, Austria, Ireland, Illinois, Germany) find no correlation between full moons and increased levels of emergencies.

  • Exceptions: Limited evidence suggests possible increased motorcycle accidents due to driver distraction during full moons.

  • Myth: Heart attacks and cardiac arrests increase during full moons.

  • Research Findings: Multiple studies (New Jersey, Austria) have found no correlation between full moons and heart attacks/cardiac arrests.

  • Myth: Psychiatric emergencies increase during full moons.

  • Research Findings: Studies (2017, Mayo Clinic) have shown no correlation between full moons and psychiatric episodes.

  • Myth: Childbirth rates increase during full moons.

  • Research Findings: Extensive studies (Ireland) have found no link between full moons and childbirth.
