RESUMO

BACKGROUND: Cardiovascular and renal diseases (CVRD) are major causes of mortality in individuals with type 2 diabetes (T2D). Studies of lifetime risk have neither considered all CVRD together nor the relative contribution of major risk factors to combined disease burden. METHODS: In a population-based cohort study using national electronic health records, we studied 473,399 individuals with T2D in England 2007-2018. Lifetime risk of individual and combined major adverse renal cardiovascular events, MARCE (including CV death and CVRD: heart failure; chronic kidney disease; myocardial infarction; stroke or peripheral artery disease), were estimated, accounting for baseline CVRD status and competing risk of death. We calculated population attributable risk for individual CVRD components. Ideal cardiovascular health was defined by blood pressure, cholesterol, glucose, smoking, physical activity, diet, and body mass index (i.e. modifiable risk factors). RESULTS: In individuals with T2D, lifetime risk of MARCE was 80% in those free from CVRD and was 97%, 93%, 98%, 89% and 91% in individuals with heart failure, chronic kidney disease, myocardial infarction, stroke and peripheral arterial disease, respectively at baseline. Among CVRD-free individuals, lifetime risk of chronic kidney disease was highest (54%), followed by CV death (41%), heart failure (29%), stroke (20%), myocardial infarction (19%) and peripheral arterial disease (9%). In those with HF only, 75% of MARCE after index T2D can be attributed to HF after adjusting for age, gender, and comorbidities. Compared with those with > 1, < 3 and ≥3 modifiable health risk behaviours, achieving ideal cardiovascular health could reduce MARCE by approximately 41.5%, 23.6% and 17.2%, respectively, in the T2D population. CONCLUSIONS: Four out of five individuals with T2D free from CVRD, and nearly all those with history of CVRD, will develop MARCE over their lifetime. Early preventive measures in T2D patients are clinical, public health and policy priorities.

RESUMO

BACKGROUND: Previous studies have addressed patients in whom treatment is withheld or withdrawn after a period of intensive care unit management. However, no studies have investigated the epidemiology of patients with treatment limitations in place at the time of intensive care unit admission. OBJECTIVE: To report the epidemiology and outcome of patients with treatment limitations at intensive care unit admission and to identify characteristics associated with survival and discharge to home. DESIGN: Retrospective database study using data from the Australian and New Zealand Intensive Care Society Adult Patient Database. SETTING: Australian and New Zealand intensive care units. PATIENTS: One hundred eighty-seven thousand four hundred and one intensive care patients collected over a 3-yr period, 5,989 (3.2%) of whom had treatment limitations at admission to the intensive care unit. INTERVENTIONS: Retrospective database study with no interventions. Data collected included patient characteristics, length of stay, mortality, and discharge destination. Mean intensive care unit bed days were used as a surrogate for resource consumption. MEASUREMENTS AND MAIN RESULTS: Between January 1, 2007, and December 31, 2009, 5,989 (3.2%) patients were reported to the Australia and New Zealand Intensive Care Society Adult Patient Database who had treatment limitation orders at admission to intensive care unit. Mortality was 53% (95% confidence interval 51.7%-54.3%) compared with 9% (95% confidence interval 8.9%-9.1%) in patients admitted for full active management (p ≤ .001). Overall, 30% of patients with treatment limitations were discharged directly to their homes. Intensive care unit bed day usage was similar between the two groups. Within the treatment limitation group, younger patients, those with less comorbid diseases, less acute physiological disturbance, and those admitted following elective surgery, were more likely to survive and be discharged home. Admission diagnosis was an important determinant of outcome with intracranial or subarachnoid hemorrhage predicting a extremely high mortality. CONCLUSIONS: Patients with treatment limitations on intensive care unit admission comprise approximately 2,000 patients per year in Australia and New Zealand. Despite such limitations, almost half of these patients survive their hospital admission and a third return directly to their home.
