ABSTRACT
Objective:
This study evaluated the usefulness, as a risk factor of 30-day mortality, in patients residing in nursing-homes (NHs) or long-term care facilities with the diagnosis of pneumonia.
Method:
We conducted a retrospective study in a public hospital between January 2017 and December 2017. The subjects included elderly patients residing in NHs and diagnosed with pneumonia in the emergency room. Data on age, gender, comorbidities, laboratory findings, pneumonia severity index score (PSI), and CURB-65 (Confusion, Urea, Respiratory rate, Blood pressure, and Age 65 or older) were entered into an electronic database.
Results:
A total of 439 patients were enrolled during the study period. The mean age was 82.1±8.0 years; 195 (44.4%) were men, and 30-day mortality was 21.8%. On multivariate Cox proportional hazard analysis, cerebrovascular accidents (hazard ratio [HR], 0.53; 95% confidence interval [CI], 0.33-0.87; P=0.012), chronic renal disease (HR, 2.28; 95% CI, 1.11-4.67; P=0.024), malignancy (HR, 1.69; 95% CI, 1.04-2.76; P=0.034), lactate (HR, 1.02; 95% CI, 1.01-1.03; P<0.001), albumin (HR, 0.52; 95% CI, 0.36-0.73; P<0.001), and red cell distribution width (RDW; HR, 1.11; 95% CI, 1.03- 1.19; P=0.007) were independently associated with 30-day mortality. Areas under the curve of PSI, RDW, albumin, lactate, and PSI+RDW+albumin+lactate were 0.690 (95% CI, 0.629-0.751), 0.721 (95% CI, 0.666-0.775), 0.668 (95% CI, 0.607-0.728), 0.661 (95% CI, 0.597-0.726), and 0.801 (95% CI, 0.750-0.852), respectively.
Conclusion:
RDW, albumin, lactate and especially the combination of PSI and these factors appear to be major determinants of 30-day mortality in NH residents with pneumonia.
