Comparison of outcomes?in emergency department patients with suspected cardiac chest pain: two-centre prospective observational?study in Southern China

摘要

Hong Kong (HK) and Guangzhou (GZ) are cities in China with different?healthcare systems. This study aimed to compare 30-day and 6-month mortality and characteristics?of?patients with suspected cardiac chest pain admitted?to two emergency departments (ED) in HK and GZ. A prospective observational study enrolled patients with suspected cardiac chest pain presenting to EDs?in?the Prince of Wales Hospital (PWH), HK and the Second Affiliated Hospital of Guangzhou Medical University (AHGZMU),GZ. The primary outcome?was 30-day and 6-month mortality. In total, 996 patients were recruited, 407 cases from GZ and 589 cases from HK.The 30-day and 6-month mortality of chest patients were 3.7% and 4.7% in GZand 0.3% and 1.9% in HK, respectively. Serum creatinine level (Cr) was an independent factor for 30-day mortality whilst Cr and systolic blood pressure (SBP) were independent factors for 6-month mortality. In Cox regression analysis, unadjusted?and adjusted hazard ratios for 30-day and 6-month mortality?in?GZ were significantly increased. The 30-day and 6-month mortality of patients with suspected cardiac chest pain in Guangzhou?were higher than?in Hong Kong due to due to different baseline clinical characteristics of patients and different distributions of diagnoses, which were associated with different healthcare systems. Serum creatinine and SBP were independent factors?for?30-day and 6-month mortality.
