Patient Population
This study was approved by the Institutional Review Board at the University of Chicago Hospitals. Eligible subjects included all patients with SA who were treated in the medical ICU at the University of Chicago Hospitals between May 1995 and May 2000 with either endotracheal intubation (ETI) and mechanical ventilation, or a minimum of 2 consecutive h of noninvasive PPV (NIPPV). Subjects were identified after analyzing the medical records of patients admitted to the ICU and billed with
Results
Seventy-nine patients were admitted a total of 105 times to the University of Chicago Hospitals Medical ICU and treated with PPV. Seventy-eight charts were available for review.
Characteristics of the study population are shown in Table 1. Nearly all (96%) of the patients were African American, and 72% were female. Fewer than half (47%) were receiving inhaled corticosteroids on presentation, while 33% had been receiving systemic steroids for > 24 h. Thirty-one percent used tobacco, and at least
Discussion
In a mostly African-American population of patients receiving PPV for SA, we found an association between increased length of hospital stay and female gender, as well as with preadmission use of inhaled corticosteroids. Both ETI and the administration of neuromuscular blockers for > 24 h were also associated with longer hospitalizations.
One of the major findings of our study is the significantly longer length of stay for women compared with men (7.1 days vs 4.8 days), even after adjusting for
