The Forum for Injection Technique (FIT) Canada emphasizes that the effectiveness of insulin therapy is largely dependent on how it is delivered. Poor technique can lead to erratic absorption, unexplained hypoglycemia, and long-term complications. These flashcards are designed to help pharmacists and healthcare professionals memorize the 4th Edition Recommendations regarding needle length selection, the prevention of lipohypertrophy, and proper site rotation.
Key Topics Covered:
Needle Selection: Memorizing the evidence that 4 mm pen needles are recommended for all adults and children, regardless of BMI, to minimize the risk of intramuscular (IM) injection.
Lipohypertrophy (LH): Identifying the impact of “lumpy” injection sites on glycemic control—specifically that injecting into LH can reduce insulin absorption by up to 25% and cause significant variability.
Site Rotation: Applying structured rotation principles, such as spacing injections at least 1 cm (approx. one finger width) apart and utilizing divided zones to preserve tissue health.
Single Use: Reinforcing the strict rule that needles and syringes are single-use devices and must be discarded immediately to prevent tip deformation and infection.
Troubleshooting: Recognizing that unexplained hypoglycemia or hyperglycemia is often a sign of injection site complications rather than a need for dose adjustment.
