Item Open Access CHANGING TRENDS IN THE USE OF VASOPRESSORS IN INTENSIVE CARE UNIT: A 7-YEAR STUDY(Critical Care Medicine, 2014-12) Srivali, Narat; Thongprayoon, Charat; Kittanamongkolchai, Wonngarm; Cheungpasitporn, Wisit; Erdogan, Aysen; Carrera, Perliveh; Kashani, KianoushLearning Objectives: The use of vasopressors was common in intensive care unit (ICU). Due to the lack of conclusive evidence in superiority in efficacy among various types of vasopressors, the choice of vasopressor use mainly depends on the physician preference. This study aims to describe the prevalence of vasopressor use and the trend in the use of each vasopressor medication in ICU over the past 7 years. Methods: This is a descriptive study conducted at a tertiary referral hospital. All ICU admissions, including both medical and surgical ICU, at our institution between January 2007 and December 2013 were included in this study. The use of vasopressors within given ICU day (12.00 am – 11.59 pm) during ICU stay was reviewed. Vasopressors were defined as the continuous intravenous administration of norepinephrine, epinephrine, dopamine, phenylephrine, or vasopressin regardless of duration and dosage. Results: A total of 52410 unique patients had 72005 ICU admissions in the course of study, (272271 patient*ICU day). Vasopressors were used in 17767 (24.7%) ICU admissions and on 53898 (19.8%) patient*ICU day, resulting in a total of 76564 vasopressor day. Vasopressin was used on 21955 (41%), epinephrine on 20958 (39%), norepinephrine on 17919 (33%), dopamine on 8636 (16%) and phenylephrine on 7096 (13%) patient*ICU day. Over 2007-2013, there was an upward trend in the use of norepinephrine (the proportion of ICU day on norepinephrine over total ICU day with vasopressor 0.24 in year 2007 to 0.45 in year 2013), and a downward trend in phenylephrine (the proportion of ICU day on phenylephrine over total ICU day with vasopressor 0.20 in year 2007 to 0.10 in year 2013). There was no specific trend in the usage of vasopressin, epinephrine, and dopamine. Conclusions: The vasopressors were used in about one fourth of ICU admission and about one fifth of ICU days. Vasopressin is the most commonly used vasopressor. The use of norepinephrine is in upward trajectory.Item Open Access Temporal trends in the utilization of vasopressors in intensive care units: an epidemiologic study.(BMC pharmacology & toxicology, 2016-05) Thongprayoon, Charat; Cheungpasitporn, Wisit; Harrison, Andrew M; Carrera, Perliveh; Srivali, Narat; Kittamongkolchai, Wonngarm; Erdogan, Aysen; Kashani, Kianoush BBackground
The choice of vasopressor use in the intensive care unit (ICU) depends primarily on provider preference. This study aims to describe the rate of vasopressor utilization and the trends of each vasoactive agent usage in the ICU over the span of 7 years in a tertiary referral center.Methods
All adult ICU admissions, including medical, cardiac, and surgical ICUs from January 1st, 2007 through December 31st, 2013 were included in this study. Vasopressor use was defined as the continuous intravenous administration of epinephrine, norepinephrine, phenylephrine, dopamine, or vasopressin within a given ICU day. The vasopressor utilization index (VUI) was defined as the proportion of ICU days on each vasoactive agent divided by the total ICU days with vasopressor usage.Results
During the study period, 72,005 ICU admissions and 272,271 ICU days were screened. Vasopressors were used in 19,575 ICU admissions (27 %) and 59,811 ICU days (22 %). Vasopressin was used in 24,496 (41 %), epinephrine in 23,229 (39 %), norepinephrine in 20,648 (34 %), dopamine in 9449 (16 %), and phenylephrine in 7508 (13 %) ICU days. The VUInorepinephrine increased from 0.24 in 2007 to 0.46 in 2013 and VUIphenylephrine decreased from 0.20 in 2007 to 0.08 in 2013 (p < 0.001 both). For epinephrine, dopamine, and vasopressin VUI did not change over the course of study.Conclusion
Vasopressors were used in about one fourth of ICU admissions and about one-fifth of ICU days. Although vasopressin is the most commonly used vasopressor, the use of norepinephrine found to have an increasing trajectory.
