Trends of hospitalisation for cardiovascular diseases among people with diabetes in Australia

Abstract

ObjectiveTo describe trends in hospitalisation for subtypes of cardiovascular diseases among people with diabetes. MethodsThe data sources included the Australian diabetes registry, admitted hospitalisation datasets, and death registry from 2011 to 2019. The outcomes comprised hospital admissions for: all CVD; all cerebrovascular diseases, ischaemic and haemorrhagic stroke; angina and ischaemic heart disease (AIHD); non-ST elevation myocardial infarction (NSTEMI), ST-elevation myocardial infarction (STEMI); atrial fibrillation and flutter (AFF). Data were analysed using Stata and Joinpoint regression software.Rates were standardised for age and sex. Annual percentage change (APC) was reported. ResultsIn type 1 diabetes, there were increases in hospitalisation for all cerebrovascular diseases (APC 4.5, 95 % CI: 1.2, 7.9) and ischaemic stroke (2.3, 95 % CI: 1.6, 3.0). There were declines in STEMI (-2.6, 95 % CI: −5.0, −0.1) and AIHD (-3.1, 95 % CI: −5.5, −0.7). In type 2 diabetes, hospitalisation for all CVD declined (-0.9, 95 % CI: −1.4, −0.3). Hospitalisation rates for ischaemic stroke increased (4.1, 95 % CI: 3.1, 5.1). There were declines in NSTEMI (-2.5, 95 % CI: −3.2, −1.8) and AIHD (-4.2, 95 % CI: −4.8, −3.5). ConclusionIn type 1 and 2 diabetes, hospitalisation for ischaemic stroke increased while coronary diagnoses declined.
