medications, and treatments do and do not work

• When following a new study, measure the results with your CQI program.

• Ambulance corps were developed during World Wars I and II to transport and rapidly care for soldiers.

• Helicopters were used to rapidly remove soldiers from the battlefield during the Korean and Vietnam Wars.

SummarySummary

• In 1966 the National Academy of Science and the National Research Council released “The White Paper” outlining 10 points. – The National Highway Safety Act and the US

Department of Transportation were created as a result.

• Paramedics must be licensed (also known as certification or credentialing) before performing any functions.

SummarySummary

• Standards for prehospital emergency care, and the people who provide it, are regulated under state law by a state office of EMS.

• There are four levels of training: emergency medical responder, emergency medical technician, advanced emergency medical technician, and paramedic.

• Paramedics may be involved in interfacility transports and transports to specialty centers.

SummarySummary

• Paramedics should be familiar with the roles and responsibilities of other health care providers and public safety agencies.

• Continuing education programs expose paramedics to new research findings and refresh their skills and knowledge.

• A physician medical director authorizes EMS providers to provide care in the field through off-line or online medical direction.

SummarySummary

• There are expected standards and a code of ethics for all paramedics.

• There are many professional attributes that a paramedic is expected to have, including but not limited to integrity, empathy, teamwork, patient advocacy, and time management skills.

SummarySummary

• Some of the primary paramedic responsibilities include preparation, response, scene management, patient assessment and care, management and disposition, patient transfer and report, documentation, and return to service.

• Paramedics evaluate their care through quality control and continuous quality improvement.

SummarySummary

• Research establishes a consensus of what EMS personnel should or should not do. Research may be quantitative or qualitative.

• There are many ethical considerations when conducting research. Researchers must always obtain consent from subjects, inform them of the research parameters, and protect their rights and welfare.

SummarySummary

• Paramedics should know how to evaluate the quality of research, including how to recognize peer-reviewed literature and how to find quality research on the Internet.
