Remote Delivery of Thrombolytics Prior to Transfer to a Regional Burn Center for Tissue Salvage in Frostbite: A Single-center Experience of 199 Patients.

While much has been published on the efficacy and safety of systemic thrombolytics in the treatment of acute frostbite, there has been limited investigation into administration outside a tertiary care setting. Here, we present a single-center experience with remote initiation of intravenous tissue plasminogen activator (tPA) at referring hospitals prior to transfer to a regional burn center. A modified Hennepin Quantification Score based on tissue involvement was used to determine eligibility for tPA and to quantify the severity of amputation. This is a retrospective review of patients with acute frostbite of the digits admitted to a single verified burn center over a 5-yr period. Of 199 patient admissions, 40 received tPA remotely pre-transfer, 32 received tPA on admission to our institution, and 127 patients did not qualify for tPA therapy according to the protocol. Comparing patients who required any amputation (n = 99, 49.7%) to those who did not, patients who received remote tPA had lower odds of any amputation compared to both those receiving tPA at our institution (OR 0.19, 95% CI 0.05-0.65, P = 0.01) and the group receiving no tPA (OR 0.14, 95% CI 0.05-0.40, P < 0.001) after controlling for confounders. Only one patient receiving pre-transfer tPA according to the protocol (2.3%) had a significant bleeding event requiring transfusion. These results support the protocolized use of thrombolytic therapy for frostbite prior to transfer to a tertiary center.

Early Palliative Care Consultation in the Burn Unit: A Quality Improvement Initiative to Increase Utilization.

Despite significant morbidity and mortality for major burns, palliative care consultation (PCC) is underutilized in this population. The purpose of this study is to examine the impact of a protocol using recommended "triggers" for PCC at a single academic burn center. This is a retrospective review of patient deaths over a 4-year period. The use of life-sustaining treatments, comfort care (de-escalation of one or more life-sustaining treatments), and do not attempt resuscitation (DNAR) orders were determined. The use of PCC was compared during periods before and after a protocol establishing recommended triggers for early (<72 hours of admission) PCC was instituted in 2019. A total of 33 patient deaths were reviewed. Most patients were male (n = 28, 85%) and median age was 62 years [IQR: 42-72]. Median-revised Baux score was 112 [IQR: 81-133]. Many patients had life-sustaining interventions such as intubation, dialysis, or cardiopulmonary resuscitation, often prior to admission. Amongst patients who survived >24 hours, 67% (n = 14/21) had PCC. Frequency of PCC increased after protocol development, with 100% vs 36% of these patients having PCC before death (P = .004). However, even during the later period, less than half of patients had early PCC despite meeting criteria at admission. In conclusion, initiation of life-sustaining measures in severely injured burn patients occurs prior to or early during hospitalization. Thus, value-based early goals of care discussions are valuable to prevent interventions that do not align with patient values and assist with de-escalation of life-sustaining treatment. In this small sample, we found that while there was increasing use of PCC overall after developing a protocol of recommended triggers for consultation, many patients who met criteria at admission did not receive early PCC. Further research is needed to elucidate reasons why providers may be resistant to PCC.

Triage and Transfer to a Regional Burn Center-Impact of a Mobile Phone App.

Telemedicine technology can be used to facilitate consultations from nonburn-trained referring providers. However, there is a paucity of evidence indicating these technologies influence transfer decisions and follow-up care. In 2016, our regional burn center implemented a mobile phone app, which allows a referring provider to send photos of the wound along with basic demographic and clinical data to the burn specialist. A retrospective review was performed on consults to our regional burn center from a Level I trauma center approximately 70 miles away with a shared electronic medical record. Patients were considered to be "down-triaged" if they could be managed locally or if the transfer could occur via personal vehicle instead of ground or air ambulance transport. During the 2-year study period, 126 consultations were made for thermal injuries. Eighty-seven patients (69%) were referred using the Burn App. Overall, 49 patients (39%) were transferred. When the subset of intermediate size (1-10% TBSA) burns were considered (n = 48), the Burn App allowed for successful "down-triage" of 12 patients (33%) referred through the app. No patient referred without the app could be "down-triaged" (P = .02). Although 57 patients (44%) were recommended for outpatient follow-up, only 42% followed up. A mobile app can be used to successfully triage patients with intermediate size burn injuries to a lower acuity of follow-up and transfer mode. However, only a minority of patients triaged to outpatient management actually follow up with a regional burn center. Telemedicine efforts should focus on improving not only initial triage, but also aftercare.

Management of medial collateral ligament injuries in the knee: an update and review.

The medial collateral ligament (MCL) is the most frequently injured ligament in the knee, with mild-to-moderate tears often going unreported to physicians. Medial collateral ligament injuries can result from both contact and noncontact sporting activities. The mainstay of treatment is nonoperative; however, operative management of symptomatic grade II and grade III injuries is considered when laxity and instability persist. The timing of surgical repair in the setting of a multiligament knee injury remains an area of controversy among surgeons, with proponents of early reconstruction of the anterior and posterior cruciate ligaments and nonoperative management of the MCL versus proponents of delayed reconstruction following nonoperative treatment of the MCL. Prophylactic bracing may continue to increase and evolve as bracing technology improves and athletic cultures change.
