Test Predicts Elderly Patients' Ability to Learn Insulin Self-Injection Technique
(HealthDay News) — A cognitive test involving animal name recall can predict which elderly patients succeed in mastering an insulin self-injection technique within one week, according to a study published online Aug. 28 in the Journal of Diabetes Investigation.
Taichi Minami, from the Yokohama City University in Japan, and colleagues evaluated whether or not a cognitive test (the number of animal names recalled in one minute) by 57 elderly inpatients with type 2 diabetes starting insulin therapy could be used as a predictor of patients' ability to acquire the insulin self-injection technique within one week.
The researchers found that the number of animal names recalled was the most reliable predictor of the ability to acquire the insulin self-injection technique within one week. Recall of 11 animal names predicted a successful acquisition, with a sensitivity of 73 percent and a specificity of 91 percent (area under the curve, 0.87; P < 0.01).
"To our knowledge, no studies have reported that cognitive tests can be used to evaluate whether or not patients can acquire the insulin self-injection technique," the authors write.
