The pulmonary artery catheter: economic aspects.
To review the literature addressing economic issues related to use of the pulmonary artery catheter (PAC). All pertinent English language articles related to economic analysis of the use of pulmonary artery catheterization were retrieved from 1977 through 1996. Articles were chosen for review if an economic analysis related to use of the PAC was studied or reviewed. From the articles selected, information was obtained about economic aspects related to pulmonary artery catheterization. Inadequate evidence exists to accurately determine if PAC use is truly cost-effective. Widespread use of the PAC has significant economic ramifications. Data regarding cost-effectiveness of the PAC is extremely limited in terms of methodology and scope. Economic impact and cost-effectiveness are moot prior to establishing clinical efficacy.
