Single-Center Experience of Outcomes and Prescribing Patterns of IV Immunoglobulin Use in Critically Ill Patients.

ABSTRACT: Previous literature has not compared prescribing practices of IV immunoglobulin in medical ICU survivors and nonsurvivors. The objective of this study was to study IV immunoglobulin use in patients admitted to a medical ICU evaluating differences between hospital survivors and nonsurvivors in regards to level of evidence supporting use, prescribing patterns, and cost.

Design

Retrospective, observational study.

Setting

Single, academic medical center medical ICU.

Patients

Adults who received greater than or equal to 1 dose of IV immunoglobulin during their medical ICU admission from 2011 to 2018.

Interventions

Prescribing patterns, level of evidence supporting use, and cost.

Measurements and main results

A total of 389 patients received greater than or equal to 1 dose of IV immunoglobulin for 46 discrete indications and 36.5% of indications had low-quality data supporting use of IV immunoglobulin. The primary indication for IV immunoglobulin was hypogammaglobulinemia (35.5%) followed by antibody-mediated lung transplant rejection (15.4%). Nonsurvivors received lower median dosing (g/kg) and number of doses compared with survivors (0.4 g/kg [0.4-1 g/kg] vs 0.5 g/kg [0.4-1 g/kg] [p = 0.0003] and 1.0 [1-2] vs 2 [1-3] doses [p = 0.0001], respectively). Dosing was based on ideal body weight in 258 patients (66%). High-quality data supported IV immunoglobulin use in 15 patients (4%). The median cost per dose of IV immunoglobulin in nonsurvivors was $4,893 ($4,078-$8,155) versus $5,709 ($4,078-$10,602) in survivors (p = 0.04).

Conclusions

IV immunoglobulin is prescribed for many indications in the medical ICU with low-quality evidence supporting its use and dosing regimens are variable. Hospital survivors received a higher dose and greater number of doses of IV immunoglobulin compared with nonsurvivors. National guidelines are needed to help inform IV immunoglobulin utilization and reduce healthcare costs.

Project description:ObjectivesCoronavirus disease 2019 is associated with high mortality rates and multiple organ damage. There is increasing evidence that these patients are at risk for various cardiovascular insults; however, there are currently no guidelines for the diagnosis and management of such cardiovascular complications in patients with coronavirus disease 2019. We share data and recommendations from a multidisciplinary team to highlight our institution's clinical experiences and guidelines for managing cardiovascular complications of coronavirus disease 2019.Design setting and patientsThis was a retrospective cohort study of patients admitted to one of six ICUs dedicated to the care of patients with coronavirus disease 2019 located in three hospitals within one academic medical center in Atlanta, Georgia.Measurements/interventionsChart review was conducted for sociodemographic, laboratory, and clinical data. Rates of specific cardiovascular complications were assessed, and data were analyzed using a chi-square or Wilcoxon rank-sum test for categorical and continuous variables. Additionally, certain cases are presented to demonstrate the sub committee's recommendations.Main resultsTwo-hundred eighty-eight patients were admitted to the ICU with coronavirus disease 2019. Of these, 86 died (29.9%), 242 (84.03%) had troponin elevation, 70 (24.31%) had dysrhythmias, four (1.39%) had ST-elevation myocardial infarction, eight (2.78%) developed cor pulmonale, and 190 (65.97%) with shock. There was increased mortality risk in patients with greater degrees of troponin elevation (p < 0.001) and with the development of arrhythmias (p < 0.001), cor pulmonale (p < 0.001), and shock (p < 0.001).ConclusionsWhile there are guidelines for the diagnosis and management of pulmonary complications of coronavirus disease 2019, there needs to be more information regarding the management of cardiovascular complications as well. These recommendations garnered from the coronavirus disease 2019 cardiology subcommittee from our institution will add to the existing knowledge of these potential cardiovascular insults as well as highlight suggestions for the diagnosis and management of the range of cardiovascular complications of coronavirus disease 2019. Additionally, with the spread of coronavirus disease 2019, our case-based recommendations provide a bedside resource for providers newly caring for patients with coronavirus disease 2019.
