Doctor--how do I use my EpiPen?

Area of Science:

• Medical Education
• Emergency Medicine
• Anaphylaxis Management

Background:

• Correct epinephrine auto-injector (EpiPen) administration is crucial for managing anaphylaxis.
• Healthcare providers' ability to demonstrate proper EpiPen use is essential for patient education.
• Gaps in provider knowledge can lead to incorrect administration and suboptimal patient outcomes.

Purpose of the Study:

• To assess the competency of junior and senior medical staff in demonstrating correct EpiPen administration.
• To identify common errors and deficiencies in EpiPen technique among healthcare professionals.
• To evaluate the effectiveness of EpiPen training provided by medical staff to patients and families.

Main Methods:

• A prospective study involving 100 medical staff (residents, senior residents, fellows/consultants) at a tertiary pediatric hospital.
• Participants were evaluated on their ability to correctly use an EpiPen trainer device using a standardized 6-step scoring system.
• Data collected included correct step demonstration, need for instruction review, and incidence of accidental self-injection.

Main Results:

• Only 2% of medical staff demonstrated all 6 EpiPen administration steps correctly.
• Common errors included insufficient hold time (>5 seconds), failure to apply adequate pressure, and accidental self-injection (16%).
• 95% of participants needed to review instructions, with only 41% correctly demonstrating after reading; 37% of demonstrations would have failed to deliver epinephrine.

Conclusions:

• A significant majority of medical staff lack the proficiency to correctly demonstrate EpiPen use.
• Inadequate training by healthcare providers compromises patient and family preparedness for anaphylaxis emergencies.
• Urgent interventions are needed to improve medical staff competency in EpiPen administration and patient education.
