More Information
  •  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.
