Stimulant Abuse in Burn Patients Is Associated With an Increased Use of Hospital Resources.

Stimulant (cocaine, methamphetamine, and amphetamine) abuse compromises the peripheral vasculature through endothelial injury. In combination with the physiologic derangements seen in burn injuries, patients abusing stimulants may have additional impairments in wound healing. A retrospective review from July 1, 2015 to July 1, 2018 was performed at an American Burn Association-verified burn center. Patients with positive urine toxicology results for stimulants (ST(+)), and those without (ST(-)), who sustained burn injuries were identified and matched by age and TBSA. The primary outcome was mortality, and secondary outcomes included total length of stay (LOS), and need-for-surgery (grafting). In total, 130 patients ST(+) and 133 ST(-) patients were identified. There were no significant differences in age (40.9 ± 13.5 vs 39.2 ± 23.7 years, P = 0.46), Inhalation Injury (12.3 vs 9.0%, P = 0.39), or nutritional status (prealbumin: 17.3 ± 6.1 vs 17.1 ± 12.7 mg/dl, P = 0.66; albumin: 3.5 ± 0.6 vs 3.6 ± 0.7 g/dl, P = 0.45). There were no differences in mortality (6.1 vs 4.5%, P = 0.55), intensive care unit LOS (9.3 ± 16.5 vs 10.2 ± 20.9 days, P = 0.81), wound infections (15.4 vs 23.9%, P = 0.07), or wound conversion (6.9 vs 3.0%, P = 0.14). ST(+) patients had a significantly longer LOS (15.0 ± 16.9 vs 10.7 ± 17.3 days, P = 0.04), greater tobacco use (56.9 vs 18.0%, P = 0.00001), and greater need for grafting (54.6 vs 33.1%, P = 0.0004). ST(+) patients require more hospital resources-surgical operations and hospital days-than ST(-) patients. The increased need for surgical intervention may partially explain the increase in hospital days, in addition to the observation that ST(+) patients had more complex disposition issues than ST(-) patients.
