Abstract

Abstract: Use of the pulmonary artery catheter (PAC) has been controversial since the late 1980s. Multi-center observational and randomized controlled trials (RCTs) have concluded that PACs fail to decrease mortality. Subsequently, studies have looked for a decline in PAC use that corresponds to the literature and have indeed found that it exists. However, none to date have looked primarily at trends in the aneurysmal subarachnoid hemorrhage (aSAH) population. This study uses the Nationwide Inpatient Sample (NIS) from 2000–2010 to identify trends in PAC use among patients with aSAH. Trend analysis was assessed using a multivariable regression model with a calculation of slope of PAC frequency over time for pre-2005 and post-2005. Trends in mortality and routine discharge were also assessed for the same time period. 363, 096 SAH patients were extrapolated using survey weights, of whom 6, 988 had a PAC. Over time, PAC use declined, with a significant downward shift in the year 2005. Analyses also showed a decrease in mortality over the same time period. Our results show that PAC use among patients with aSAH decreased from 2000 to 2010. Similar to other studies, the decline appears to be temporally related to RCTs that showed a lack of benefit from PAC. Studies such as these have the potential to influence clinical practice through illumination of shifting opinions and approaches.
