Differences between groups according to their baseline clinical characteristics, admitting etiology and outcome are given in Table 1.
The three groups were comparable at enrollment (P > 0.05) with respect to baseline demographic characteristics, admitting diagnosis, severity score and laboratory values.
Atypical LAT and oral AP groups appeared well balanced with respect to mean age (42.1 vs 42.4 years, p = .5622), gender (43.6% vs 44.6% female, p = .5345), race, region, payer type, hospital characteristics, admitting diagnosis, admitting physician specialty, and degree of illness severity (p > .05 for all).
The Table 44 compares characteristics of admitted and non-admitted patients.
Baseline characteristics of admitted patients are shown in Table 1.
To assess the correlation between clinical characteristics of admitted patients with epidemic periods, we identified three time frames based on the varying densities of admitted patients noted during the study period.
To calculate receiver operating characteristics, those admitted were divided into three groups and the area under the curve calculated for adjacent pairs of groups - open wards -v- psychiatric intensive care units, psychiatric intensive care units -v- medium/high security.
A comparison of hospital mortality between hospitals does not show hospital quality directly, because the number of hospital deaths is likely to be influenced by the characteristics of admitted patients.
After controlling for baseline patient, physician and ICU characteristics, patients admitted by a physician from the Pulmonary group had significantly less chance of dying in the ICU (OR: 0.69; 95% CI: 0.52 to 0.94) compared to those admitted by the AGSEM group.
