Introduction: Proper insulin injection technique is important for optimal glycaemic control, yet patients with diabetes often inject insulin incorrectly. Previous studies identified common errors in insulin injection in Canada, and this article seeks to evaluate the current insulin injection technique practices among patients and explore the effectiveness of feedback and education in improving their technique.
Methods: The study recruited 147 patients and 16 physicians across Canada to gather insights into current insulin injection practices and education gaps. Eligible patients were people living with diabetes who inject insulin using an insulin pen and pen needles. Eligible physicians, who were unsupported by diabetes educators, completed a practice assessment survey and selected 10 eligible patients to complete a baseline assessment survey. During the patient visit, if an error in the patient's technique was identified, a pop-up knowledge transfer (KT) prompt would appear, providing feedback and information on best practices at the point of care. Follow-up surveys were completed 1-3 months later.
Results: Physicians reported facing barriers to providing education and feedback, including lack of time and personnel, and lack of effective educational material. Patients demonstrated modest improvements in some injection technique domains at their follow-up visit, including injection force factors, time the needle was held in the skin, pen needle reuse, injection area size, and injection angle. The most common initial mistakes by patients were selecting an area smaller than recommended and not paying attention to the injection force. At the second visit, patients reduced an average of one error in their injection technique.
Conclusion: Results showed that basic feedback by their physician during one visit could exert moderate improvements on patients' injection technique. Proper injection technique is critical for diabetes management, and incorporating targeted ongoing education and support can significantly enhance physician practices, ultimately reducing risks and improving outcomes.
