The aim of this project was to improve the self-management of diabetes among elderly residents in a Belgian home for the aged. Diabetes is a common chronic condition with significant comorbidity. Incidence is increasing, but a third of patients with diabetes are unaware that they have the disease. The treatment of diabetes requires a multifactorial approach. Treatment guidelines on diabetes recommend involving patients in monitoring their condition because supported self-management improves daily glycemic control. This evidence implementation project used the JBI Evidence Implementation Framework, which follows three phases. In the first phase, the area of change, stakeholders' role, and practice context and readiness for change are investigated. In the second phase, a baseline audit is conducted to compare current practice with best practice. Strategies are then implemented to address any areas of non-compliance with best practice. In the third phase, a follow-up audit is conducted to evaluate changes in practice. At baseline, six criteria had 0% compliance, two criteria had compliance lower than 50%, and only 49% of health care workers were familiar with the procedure for hypoglycemia treatment. Improvement strategies included creating awareness among health workers. In the follow-up audit, one criterion improved from 0% to 100%, three criteria improved from 0% to 85%, two criteria reached the threshold of 50% compliance, and one criterion reached 19%. Further audits are needed to ensure sustainability. This project improved diabetes self-management in elderly people living in a Belgian home for the aged. An in-depth planning phase with internal facilitation and interdisciplinary collaboration between all co-workers addressed barriers related to quality systems, structure, communication, and education. http://links.lww.com/IJEBH/A258.
