Abstract

PURPOSE:  To understand the hemoglobin (Hb) thresholds US Intensivists (ICUMDs) use to assess and manage anemia in critically ill COPD patients (ICU-COPD).

METHODS:  A survey was conducted to identify Hb thresholds representing presence and severity of anemia in ICU-COPD.

RESULTS:  Ninety-nine ICUMDs, who care almost exclusively for adult patients, completed the survey at a specialty society meeting in 2005. All were either certified or eligible in Critical Care, with the specialty of Pulmonology in 31%, Internal Medicine 45%, Surgery/Trauma 20%, Anesthesia 18%, and other 8%. 30% have been in practice for <5 years, with 41% and 29% in practice for 5-15 years and >15 years, respectively. 48% work in a university-affiliated hospital, and 42% and 34% are affiliated with hospitals with >500 total and >50 ICU beds, respectively. Over 70% of responders see >80% of their patients in a hospital setting, and >1/3 spend >80% of their time in the ICU. Of the mean 36±27 ICU pts seen/week, on the average 13±14 (36%) are estimated to have COPD, with 9±9 (69%) on mechanical ventilation (MV). Over 2/3 of the responders didn’t consider even mild anemia to be present above an Hb threshold of 10g/dL, and nearly 3/4 deemed severe anemia to be present only at Hb≤7g/dL. Despite this, over 50% utilize Hb≥8g/dL as a transfusion threshold for ICU-COPD, regardless of their MV status. Interestingly, 58% and 59% of the responders identified Hb≥10g/dL as the optimal Hb level in these patients off and on MV, respectively.

CONCLUSION:  Despite the accepted WHO definition of anemia (men, Hb<13g/dL; women, Hb<12g/dL), the majority of ICUMDs surveyed do not consider anemia to be present in ICU-COPD until the Hb is ≤10g/dL, and consider severe anemia to be present only at Hb≤7g/dL.

CLINICAL IMPLICATIONS:  Consistent with the findings of the recent Canadian survey by Hebert et al (Crit Care Med 2005), in the US much like in Canada, utilization of 7g/dL as the transfusion threshold (Hebert et al, NEJM 1999) is far from ubiquitous.
