Evaluation of the incidence of errors and related factors in the use of blood glucose control medications in an elderly population with type 2 diabetes

The pace of population aging is increasing around the world. Medication errors are more common among the elderly for a variety of reasons and can lead to serious complications.

The aim of this study was to determine the incidence of errors and related factors in the use of blood glucose control medications in a diabetic elderly population in Qom, Iran. Setting and Design: This descriptive, correlational study was conducted on the elderly with type II diabetes, who were referred to the diabetes centers of Qom. The sample size was measured to be 200, based on the available sampling method.

Data were collected using a demographic questionnaire, as well as a researcher-made Medication errors questionnaire. Statistical Analysis Used: SPSS version 20 was used to analyze the data.

Overall, 69% of the samples were female, and the mean age of the participants was 63.59 ± 4.84 years. The incidence of medication errors was 69% among older patients. There was a significant relationship between medication error and polypharmacy (P < 0.001), comorbidities (P < 0.025), duration of diabetes(P < 0.026), and use of aids(P < 0.038). Forgetfulness(26.33%) and lack of drug information (12.61%) were the most common causes of medication errors in patients.

The results showed that the incidence of medication errors, which was influenced by various factors, was high among the elderly. Therefore, to prevent and reduce the incidence of medication misuse, proper measures should be taken.
