Gender- and race-based utilization and outcomes of pulmonary artery catheterization in the setting of full-time intensivist staffing.

Background: Little is known regarding gender- or race-based differences in critical care. We investigated whether gender or race was associated with pulmonary artery catheter (PAC) utilization or with in-hospital death among patients with a PAC. A particular focus was patients with cardiogenic shock (CS), in whom guidelines recommend PAC use.

Methods: This was a retrospective cohort analysis from the coronary care unit of a large tertiary-care hospital staffed with full-time cardiac intensivists.

Results: We analyzed 8845 consecutive adult patients, of whom 42.1% were women and 40.8% were black. PAC use rates were 11.3% in women and 11.5% in men (P = 0.79), and 11.3% in blacks and 11.5% in whites (P = 0.76). In CS patients, PAC use rates in women and men were 50.3% and 49.1% (P = 0.85) and in blacks and whites were 43.7% and 53.3% (P = 0.05). There was no independent association between gender or race and PAC use overall or in those with CS. Neither gender nor race was a predictor of in-hospital death in patients undergoing PAC.

Conclusions: PAC use and in-hospital death were determined not by gender or race but by disease severity. Full-time intensivist staffing and the presence of definitive guidelines may reduce gender- and race-based treatment disparities.
