Inpatient Complications and Outcomes for Burn Patients Admitted with Methamphetamine Intoxication.

Methamphetamine intoxication frequently complicates inpatient burn admissions. While single-institution studies describe adverse outcomes during resuscitation, little is known about the risks of amphetamine intoxication on inpatient complications and perioperative management. The US National Trauma Data Bank was queried for burn encounters between 2017-2021. Amphetamine intoxication was identified on admission. Primary outcomes included death, stroke, and myocardial infarction (MI). Secondary outcomes included organ failure and surgical management. Multivariable regressions modeled outcomes adjusting for available covariates including demographics, total body surface area (TBSA) burned, and inhalation injury. Bonferroni adjustments were applied. Our study identified a total of 73,968 primary burn encounters with toxicology screens. Among these, 800 cases (1.1%) were found to have positive methamphetamine drug screens upon admission. Methamphetamine users were significantly older (41.7 versus 34.9 years, p<.001), had a greater percentage of males (69.6 vs. 65.4, p=.045), were more likely to have inhalation injury (p<.001) and had larger %TBSA burns (16% vs. 13%, (p<.001). Methamphetamine users were no more likely to die, experience MI, or experience stroke during admission. In contrast, methamphetamine users were significantly more likely to have alcohol withdrawal (p=.019), AKI (p<.001), deep vein thrombosis (DVT) (p=.001) , pulmonary embolism (PE) (p=.039), sepsis (p=.026), and longer ICU stays (p<.001). Methamphetamine use was associated with a longer number of days to first procedure (p=.005). Of all patients who required surgery (15.0%), methamphetamine users required significantly more total debridements and reconstructive procedures (p<.001). While not associated with mortality, methamphetamine intoxication was associated with an increased risk of many complications including PE, DVT, AKI, sepsis, and longer ICU stays. Methamphetamine intoxication was associated with delays in surgical care.
