Many primary care professionals manage injection or infusion therapies in patients with diabetes. Few published guidelines have been available to help such professionals and their patients manage these therapies. Herein, we present new, practical, and comprehensive recommendations for diabetes injections and infusions. These recommendations were informed by a large international survey of current practice and were written and vetted by 183 diabetes experts from 54 countries at the Forum for Injection Technique and Therapy: Expert Recommendations (FITTER) workshop held in Rome, Italy, in 2015. Recommendations are organized around the themes of anatomy, physiology, pathology, psychology, and technology. Key among the recommendations are that the shortest needles (currently the 4-mm pen and 6-mm syringe needles) are safe, effective, and less painful and should be the first-line choice in all patient categories; intramuscular injections should be avoided, especially with long-acting insulins, because severe hypoglycemia may result; lipohypertrophy is a frequent complication of therapy that distorts insulin absorption, and, therefore, injections and infusions should not be given into these lesions and correct site rotation will help prevent them; effective long-term therapy with insulin is critically dependent on addressing psychological hurdles upstream, even before insulin has been started; inappropriate disposal of used sharps poses a risk of infection with blood-borne pathogens; and mitigation is possible with proper training, effective disposal strategies, and the use of safety devices. Adherence to these new recommendations should lead to more effective therapies, improved outcomes, and lower costs for patients with diabetes.

PurposeThe purpose of the study is to assess whether proper Injection Technique (IT) is associated with improved glucose control over a three month period.MethodsPatients (N = 346) with diabetes from 18 ambulatory centers throughout northern Italy who had been injecting insulin ≥ four years answered a questionnaire about their IT. The nurse then examined the patient's injection sites for the presence of lipohypertrophy (LH), followed by an individualized training session in which sub-optimal IT practices highlighted in the questionnaire were addressed. All patients were taught to rotate sites correctly to avoid LH and were begun on 4 mm pen needles to avoid intramuscular (IM) injections. They were instructed not to reuse needles.ResultsNearly 49% of patients were found to have LH at study entry. After three months, patients had mean reductions in HbA1c of 0.58% (0.50%–0.66%, 95% CI), in fasting blood glucose of 14 mg/dL (10.2–17.8 mg/dL, 95% CI) and in total daily insulin dose of 2.0 IU (1.4–2.5 IU, 95% CI) all with p < 0.05. Follow-up questionnaires showed significant numbers of patients recognized the importance of IT and were performing their injections more correctly. The majority found the 4 mm needle convenient and comfortable.ConclusionsTargeted individualized training in IT, including the switch to a 4 mm needle, is associated with improved glucose control, greater satisfaction with therapy, better and simpler injection practices and possibly lower consumption of insulin after only a three month period.

Background:  The efficacy of injection therapy in diabetes depends on correct injection technique and, to provide patients with guidance in this area, we must understand how they currently inject. Methods:  From September 2008 to June 2009, 4352 insulin‐injecting Type 1 and Type 2 diabetic patients from 171 centers in 16 countries were surveyed regarding their injection practices. Results:  Overall, 3.6% of patients use the 12.7‐mm needle, 1.8% use the 12‐mm needle, 1.6% use the 10‐mm needle, 48.6% use the 8‐mm needle, 15.8% use the 6‐mm needle, and 21.6% use the 5‐mm needle; 7% of patients do not know what length of needle they use. Twenty‐one percent of patients admitted injecting into the same site for an entire day, or even a few days, a practice associated with lipohypertrophy. Approximately 50% of patients have or have had symptoms suggestive of lipohypertrophy. Abdominal lipohypertrophy seems to be more frequent in those using the two smaller injection size areas, and less frequent in those using larger areas. Nearly 3% of patients reported always injecting into lipohypertrophic lesions and 26% inject into them sometimes. Of the 65% of patients using cloudy insulins (e.g. NPH), 35% do not remix it before use. Conclusions:  It is clear from the latest survey that we have improved in certain areas, but that, in others, we have either not moved at all or our efforts have not yielded the results we expected.
