OBJECTIVE: To determine rates and predictors of albumin administration, and estimated costs in hospitalized adults in the United States.
DESIGN: Cohort study of adult patients from the University HealthSystem Consortium database from 2009 to 2013.
SETTING: One hundred twenty academic medical centers and 299 affiliated hospitals.
PATIENTS: A total of 12,366,264 hospitalization records.
INTERVENTIONS: Analysis of rates and predictors of albumin administration, and estimated costs.
MEASUREMENTS AND MAIN RESULTS: Overall the proportion of admissions during which albumin was administered increased from 6.2% in 2009 to 7.5% in 2013; absolute difference 1.3% (95% CI, 1.30-1.40%; p < 0.0001). The increase was greater in surgical patients from 11.7% in 2009 to 15.1% in 2013; absolute difference 3.4% (95% CI, 3.26-3.46%; p < 0.0001). Albumin use varied geographically being lowest with no increase in hospitals in the North Eastern United States (4.9% in 2009 and 5.3% in 2013) and was more common in bigger (> 750 beds; 5.2% in 2009 and 7.3% in 2013) compared to smaller hospitals (< 250 beds; 4.4% in 2009 to 6.2% in 2013). Factors independently associated with albumin use were appropriate indication for albumin use (odds ratio, 65.220; 95% CI, 62.459-68.103); surgical admission (odds ratio, 7.942; 95% CI, 7.889-7.995); and high severity of illness (odds ratio, 8.933; 95% CI, 8.825-9.042). Total estimated albumin cost significantly increased from $325 million in 2009 to $468 million in 2013; (absolute increase of $233 million), p value less than 0.0001.
CONCLUSIONS: The proportion of hospitalized adults in the United States receiving albumin has increased, with marked, and currently unexplained, geographic variability and variability by hospital size.
