Inhaled Pulmonary Vasodilator Utilization and Cost Following Initiation of a Protocol in a Quaternary Academic Heart Center Intensive Care Unit
2021
Abstract Objectives Examine the use of inhaled nitric oxide (iNO) and inhaled epoprostenol (iPGI2) before and after implementation of an iPGI2-preferential protocol and associated cost differences after rollout. Design Single center, retrospective. Setting Quaternary university hospital. Participants All patients admitted to the Heart Center Intensive Care Unit (HCICU) who required inhaled pulmonary vasodilator use December 2017 - November 2019. Interventions None. Measurements and Main Results The HCICU comprised 84% of hospital-wide iNO utilization and 59% of hospital-wide iPGI2 use across the entire study period. There was no significant difference in postsurgical HCICU admission rates across the study period. There was a significant decrease in iNO mean monthly use from 578±230 to 69±71 hours and a concurrent significant increase in iPGI2 from 756±443 to 1,210±547 hours after implementation of a protocol. There were no changes in the average length of ICU stay between the two time periods. Protocol implementation led to a projected annual savings of roughly $1,180,000. Conclusions These findings show that multidisciplinary protocol development and implementation can have a substantial impact on medication utilization and lead to significant reductions in cost.
