| description | Background: Dexmedetomidine may expedite recovery from acute kidney injury (AKI) in critically ill adults. Methods: This study utilizes data from the fourth edition of the Medical Information Mart for Intensive Care (MIMIC-IV). Adult patients admitted to Beth Israel Deaconess Medical Center in Boston, Massachusetts, between 2008 and 2019 with AKI and who have at least two serum creatinine values recorded in the MIMIC-IV database meet study inclusion criteria. The primary outcome measure is the time (days) from diagnosis of AKI to recovery. Secondary outcome measures are hospital and ICU length of stay (LOS) as well as in-hospital mortality. Results: A total of 1893 patients are included in this study. While 293 patients received dexmedetomidine, 1600 patients did not receive dexmedetomidine. Treatment with dexmedetomidine is associated with a 53.7% (95% CI: 46.8%–59.8%) decrease in the risk of recovery from AKI, on average, and this value is statistically significant ( p < 0.001). Sensitivity analysis utilizing Cox regression of dexmedetomidine rate on time to AKI recovery demonstrated the opposite effect, however, with an adjusted HR of 1.42 (95% CI: 1.24–1.63, p value <0.001). Theories for this opposite effect are explored in the Discussion section of the manuscript. For patients who receive dexmedetomidine, hospital and ICU LOS, on average, increase by 18.98% and 32.56%, respectively ( p value <0.001). Patients who receive dexmedetomidine have 0.6 times the odds of in-hospital mortality, on average, compared to patients who do not receive dexmedetomidine, which is statistically significant ( p value 0.006). Conclusion: Dexmedetomidine may be associated with slower recovery from AKI in critically ill adults. The prolonged hospital and ICU LOS associated with dexmedetomidine may be related to reduced mortality, but these results require additional investigation. These exploratory results warrant further investigation to better understand the clinical implications of dexmedetomidine exposure in the setting of AKI. |
