Identifying the need for simplification of type 2 diabetes mellitus treatment in residents of aged-care facilities: a meta-analysis and systematic review of the literature
Keywords:type 2 diabetes mellitus, aged-care facilities, frailty, dementia
Background: The management of type 2 diabetes mellitus (T2DM) in frail older adults is made challenging by the impact of physical and cognitive decline on self-monitoring of blood glucose (BG), administration of medications, especially injectable therapies, and risk of hypoglycaemia.
Aims and objectives: (1) To revisit the prevalence of hypoglycaemia in adults with T2DM living in aged-care facilities; (2) to evaluate the impact of simplification of T2DM treatment on quality of life (QOL), morbidity and mortality in this population; and (3) to identify higher risk older adults in whom simplification of therapy will be most appropriate.
Methods: MEDLINE was searched using the following concept areas: aged-care facilities, T2DM, anti-diabetic therapies, morbidity, mortality and QOL. Results (and additional literature identified by citation checking) were screened and assessed against pre-defined eligibility criteria. Standardised structures for extracting, appraising and reporting the literature were used.
Results: Hypoglycaemia is common in adults with T2DM in aged-care facilities. Glycated haemoglobin (HbA1c) needs to be interpreted cautiously in this cohort, with additional capillary BG monitoring needed to identify individuals at risk of hypo- or hyperglycaemia. Simplification of T2DM treatment can reduce morbidity and mortality in frail older adults.
Conclusion: In residents of aged-care facilities, simplification of T2DM treatment can help deliver optimal individualised patient-centred care and improve QOL.
