Introduction
Complex injection procedures are usually recommended for insulin-treated patients. Traditionally, patients on insulin have been instructed to use ‘aseptic technique’ precautions against infection at the injection site [1.2]. However, there is a growing trend towards simplification, without added risk for the patient. In a recent article Borders et al. [3] showed that non-compliance with complex insulin injection procedures is commonplace. They further suggested that modification of traditional teaching methods may result in financial savings, improved patient self-care success and enhanced health care provider credibility. The diabetic patient learning to inject insulin has to acquire several skills, and numerous mistakes may be made in teaching them. This chapter describes those that occur frequently among patients and/or health care professionals. Avoidance of ‘obAddress

Patients’ errors often result from ignorance. forgetfulness (&Ididn’t know’, ‘I forgot that’) and/or misunderstanding (‘I didn’t realize the consequence would be .‘). Health care professionals’ mistakes usually result from underestimation of the complexity of the task that they are teaching. An injection is such a routine procedure for HCPs that the different steps involved in the process seem self-evident. They should, however, bear in mind that learning self-injection is technically and emotionally demanding for the novice insulin user, who must grasp each successive step in the injection process. Beginnings are always difficult and give rise to anxiety; time is always needed to master the different steps involved, whether the technique to be learned be driving a car, wind-surfing or insulin injection.

Insulin injections: key situations/actions 1. Choice of material - Disposable syringe -- Clear graduation - Preferable incorporated needle - One concentration per syringe - Importance of checking material 2. Time schedule - Fix injection and meal times
with patient before starting insulin 3. Setting ~ Handwashing
Mistakes and attitudes of patient
Mistakes and attitudes of doctor/nurse
- Does not know type of syringe used - Cannot ensure that prescription is correctly renewed
- Syringe prescription too vague - Does not inform patient well about syringe make, graduation, etc. - Does not check if material corresponds to prescription
~ Does not bring injection material to consultation
- Does not understand importance of meal and injection times
- Neglects patient’s usual timetable when planning new one
- Fails to wash hands before injection
~ Gives unnecessarily complicated instructions for hand asepsis - Does not make patient comfortable ~ Unaware that patients misread due to light conditions. Believes patient is incapable of taking correct dose - Unaware that patient wears glasses at all, or should be wearing them
- Patient’s position
- Cannot decide to sit or stand
~ Light conditions
- Does not realize need for good light (graduation, bubbles)
- Glasses
- Forgets to wear glasses. Does not bring glasses to consultation
4. Filling a syringe - Insulin vial
- Filling a syringe
- Draw up additional insulin to leave margin for elimination of air bubbles at plunger or needle end
~ Does not shake vial - Injects supernatant when vial is full and concentrated insulin when it is nearly empty - Does not express fear or incomprehension about injection - Does not draw up additional insulin to eliminate air bubbles
- Automatically shakes vial without explaining why, or facilitating patient’s own discovery of why vial should be shaken before filling syringe - Believes job is done once he/she has demonstrated syringe filling - Fails to explain that elimination technique depends on bubbles at plunger or needle end

Insulin injections in type 2 diabetes

Insulin treatment not only involves daily injections but also regular urine or blood sugar tests. a fixed time schedule, regular carbohydrate intake at mealtimes and snacks. Non-insulin-dependent diabetes (NIDDM) patients have often been on dietary treatment, with or without oral agents, for months or even years before being put on insulin. They are bound to react to the announcement that insulin is required. Using the ‘Stages of Acceptance’ [4] we have observed that non-insulin-treated patients tend to deny the existence of their illness and consider diabetes synonymous with insulin treatment. The attitude of denial is facilitated by the fact that. unlike insulin-depen-

often make mistakes, and have given ‘hints’, where appropriate, on how to avoid them. Mistakes will vary with patient age, dexterity, eyesight, degree of acceptance of the disease, injection training, and many other factors. It is beyond the scope of this article to provide an exhaustive list of guidelines. Each health care professional should adapt it to patients’ specific needs. Conclusions
Going onto insulin involves far-reaching changes in the daily life of the diabetic patient. The difficulty of this task is undisputed. Modifying a patient’s lifestyle may be the greatest challenge to those engaged in patient education. Teaching the NIDDM patient to manage insulin is arduous. It requires patience and perseverance on the part of both patient and health care providers. In order to ensure the success of insulin treatment it should be made as safe and easy as possible for the patient. Avoiding unnecessarily complex techniques and adapting the treatment strategy to each patient’s needs should help improve patient compliance. Systematic studies evaluating different forms of injection training are required in order to improve the efficiency of patient education.
