We aimed to establish a risk score for predicting 60-day survival
in patients hospitalized with liver abscess, using Nationwide
Hospital Admission Data from 2009 to 2013 provided
by the National Health Security Office (NHSO), Thailand. All
patients with a primary diagnosis of pyogenic liver abscess and
amoebic liver abscess (ICD10-K750, A064) were included.
Baseline characteristics, comorbidities, hospital course, and
survival were analyzed, and all-causes mortality data were
retrieved from national death registration. A total of 11,296
admissions comprised of 8,423 patients from 844 hospitals
across Thailand were eligible for analysis. The mean age was
52±17 years and 66.1% of patients were male. Median length
of hospitalization was 8 days (IQR 4 to 13 days), and the
mean cost of hospitalization was 846±1,574 USD. Overall
in-hospital mortality rate was 2.8%, and overall long-term survival
was significantly higher among patients with amoebic
liver abscess compared to pyogenic liver abscess (HR 0.54;
95% CI, 0.42-0.68; p
