Table 5 Multivariable analyses for antibiotic prescribing, intensive care measures, Hospital LOS, and 30-day mortality for African-American and Caucasian VHA patients with CAP admitted to the intensive care units (ICU patients) (n = 5,172)*

From: Disparities of Care for African-Americans and Caucasians with Community-Acquired Pneumonia: A Retrospective Cohort Study

Dependent variable

HR/OR (95% CI)

Guideline-concordant antibiotics†

0.99, 0.81-1.20

Intensive care measures

 

   Vasopressors

1.27, 1.04-1.55

   Mechanical ventilation

1.40, 1.15-1.70

LOS‡

0.84, 0.76-0.93

30-day mortality

0.82, 0.68-0.99

  1. LOS = length of stay.
  2. * Hazard ratios, odds ratios, and 95% confidence intervals were calculated from the generalized linear mixed-effects models. Covariates included all 18 variables listed in Table 1 plus a hospital-level variable. Hazard ratios were reported for hospital LOS; whereas, odds ratios were reported for everything else. For LOS, hazard ratios <1 indicate shorter lengths of stay; whereas, hazard ratios >1 indicate longer lengths of stay.
  3. † Guideline-concordant antibiotics were those consistent with 2007 American Thoracic Society/Infectious Diseases Society of America community-acquired pneumonia guidelines[12]. See study methods for more information.
  4. ‡ VHA patients who died within 30 days of hospital discharge were excluded from all LOS analyses.
