BACKGROUND: Few studies from developed countries have quantitatively characterized the clinical characteristics and outcomes of patients receiving contemporary intensive cardiac care. We sought to investigate these data in patients admitted to a Chinese intensive cardiac care unit (ICCU).
METHODS: We conducted a retrospective study using data from 2,337 consecutive admissions to the ICCU at a large centre in China from June 2016 to May 2017. Data were captured after systematic inspection of individual medical records regarding current demographics, primary diagnosis, comorbidities, illnesses severity, and in-hospital outcomes.
RESULTS: The mean age was 65.6 ± 14.2 years, and females accounted for 32.0% of patients. The Charlson Comorbidity Index and Oxford Acute Severity of Illness Score were 2.4 ± 1.8 and 22.5 ± 10.4, respectively. The top reason for admission was ST-segment elevation myocardial infarction (32.0%), and nonischaemic heart diseases accounted for 31.2% of all primary diagnoses. Noncardiovascular diseases were prevalent in the ICCU population, including chronic illnesses and acute noncardiovascular critical illnesses (ANCIs); in particular, 21.7% of patients were marked by acute respiratory failure (14.6%), acute kidney injury (13.7%), sepsis (4.2%), or gastrointestinal bleeding (3.3%). The median length of stay in the ICCU and hospital were 1.1 days [interquartile range (IQR): 0.8-2.6 days] and 6.3 days (IQR: 3.8-10.9 days), respectively. The overall incidence of in-hospital death or discharge against medical advice under extremely critical conditions was 7.6% (n = 177). Multivariate logistic regression analysis showed that the complexity of chronic illnesses and incident ANCIs were strong independent determinants for in-hospital outcomes.
CONCLUSIONS: Remarkable patient diversity and breadth of critical illnesses were observed in a Chinese ICCU population. Particularly, noncardiovascular diseases were prevalent and associated with adverse outcomes. Reformation of organization and staffing practices may be considered to adapt to the changed landscape.
