Strategies to prevent suppurative chondritis following auricular burns: a systematic review.

OBJECTIVE: Suppurative chondritis is a potentially devastating complication of burns to the ear. The infection and inflammation can liquify cartilage, leading to significant aesthetic deformities which are difficult to treat. This article reviews published measures for preventing post-burn chondritis. METHOD: A comprehensive search of all available literature up to September 2020 was performed, according to PRISMA guidelines, for studies assessing preventive measures for post-burn chondritis. Randomised controlled trials (RCT), cohort studies, case-control studies, case reports and series were eligible for inclusion. RESULTS: A total of 10 studies, including one RCT and nine retrospective observational analyses, were included, incorporating 1369 patients with burns to the ear. The most common interventions were pressure avoidance (70%), daily cleansing (60%), topical mafenide acetate (60%) and targeted debridement (30%). Packages of measures which included pressure avoidance were the most effective, all of which achieved a chondritis incidence of <6%. CONCLUSION: Low-level but strong published evidence suggests that important treatment principles include prevention by pressure relief, targeted debridement, prophylactic local antibiotics, local antisepsis and the avoidance of desiccation.

Traumatic Brain Injury in Older Adults: Characteristics, Outcomes, and Considerations. Results From the American Association for the Surgery of Trauma Geriatric Traumatic Brain Injury (GERI-TBI) Multicenter Trial.

OBJECTIVES: Describe the epidemiology of a large cohort of older adults with isolated traumatic brain injury (TBI) and identify predictors of mortality, palliative interventions, and discharge to preinjury residence in those presenting with moderate/severe TBI. DESIGN: Prospective observational study of geriatric patients with TBI enrolled across 45 trauma centers. SETTING AND PARTICIPANTS: Inclusion criteria were age ≥40 years, and computed tomography (CT)-verified TBI. Exclusion criteria were any other body region abbreviated injury scale score >2 and presentation at enrolling center >24 hours after injury. METHODS: The analysis was restricted to individuals aged ≥65 and stratified into 3 age groups: young-old (65-74), middle-old (75-84), and oldest-old (≥85). Demographic, clinical, and injury data were collected. Predictors of mortality, palliative interventions, and discharge to preinjury residence in the moderate/severe TBI group were identified using Classification and Regression Tree and Generalized Linear Mixed Models. RESULTS: Of the 3081 subjects enrolled in the study, 2028 were ≥65 years old. Overall, 339 (16.7%) presented with a moderate/severe TBI and experienced a 64% mortality rate. A Glasgow Coma Scale (GCS) score <9 was the main predictor of mortality, CT worsening (odds ratio [OR] = 1.7, P < .04), cerebral edema (OR = 2.4, P < .04), GCS <9, and age ≥75 (OR = 2.1, P = .007) were predictors for palliative interventions, and an injury severity score ≤24 (OR = 0.087, P = .002) was associated with increased likelihood of discharge to preinjury residence in the moderate/severe TBI group. CONCLUSION AND IMPLICATIONS: In this prospective study of a large cohort of older adults with isolated TBI, comparisons across the older age groups with moderate/severe TBI revealed that survival and favorable discharge disposition were influenced more by severity of injury rather than age itself. Indicating that chronological age alone maybe insufficient to accurately predict outcomes, and increased representation of older adults in TBI research to develop better diagnostic and prognostic tools is warranted.

Trauma resource pit stop: increasing efficiency in the evaluation of lower severity trauma patients.

BACKGROUND: Overtriage of trauma patients is unavoidable and requires effective use of hospital resources. A 'pit stop' (PS) was added to our lowest tier trauma resource (TR) triage protocol where the patient stops in the trauma bay for immediate evaluation by the emergency department (ED) physician and trauma nursing. We hypothesized this would allow for faster diagnostic testing and disposition while decreasing cost. METHODS: We performed a before/after retrospective comparison after PS implementation. Patients not meeting trauma activation (TA) criteria but requiring trauma center evaluation were assigned as a TR for an expedited PS evaluation. A board-certified ED physician and trauma/ED nurse performed an immediate assessment in the trauma bay followed by performance of diagnostic studies. Trauma surgeons were readily available in case of upgrade to TA. We compared patient demographics, Injury Severity Score, time to physician evaluation, time to CT scan, hospital length of stay, and in-hospital mortality. Comparisons were made using 95% CI for variance and SD and unpaired t-tests for two-tailed p values, with statistical difference, p<0.05. RESULTS: There were 994 TAs and 474 TRs in the first 9 months after implementation. TR's preanalysis versus postanalysis of the TR group shows similar mean door to physician evaluation times (6.9 vs. 8.6 minutes, p=0.1084). Mean door to CT time significantly decreased (67.7 vs. 50 minutes, p<0.001). 346 (73%) TR patients were discharged from ED; 2 (0.4%) were upgraded on arrival. When admitted, TR patients were older (61.4 vs. 47.2 years, p<0.0001) and more often involved in a same-level fall (59.5% vs. 20.1%, p<0.0001). Undertriage was calculated using the Cribari matrix at 3.2%. DISCUSSION: PS implementation allowed for faster door to CT time for trauma patients not meeting activation criteria without mobilizing trauma team resources. This approach is safe, feasible, and simultaneously decreases hospital cost while improving allocation of trauma team resources. LEVEL OF EVIDENCE: Level II, economic/decision therapeutic/care management study.

Factors associated with receipt of intracranial pressure monitoring in older adults with traumatic brain injury.

BACKGROUND: The Brain Trauma Foundation (BTF) Guidelines for the Management of Severe Traumatic Brain Injury (TBI) include intracranial pressure monitoring (ICPM), yet very little is known about ICPM in older adults. Our objectives were to characterize the utilization of ICPM in older adults and identify factors associated with ICPM in those who met the BTF guidelines. METHODS: We analyzed data from the American Association for the Surgery of Trauma Geriatric TBI Study, a registry study conducted among individuals with isolated, CT-confirmed TBI across 45 trauma centers. The analysis was restricted to those aged ≥60. Independent factors associated with ICPM for those who did and did not meet the BTF guidelines were identified using logistic regression. RESULTS: Our sample was composed of 2303 patients, of whom 66 (2.9%) underwent ICPM. Relative to Glasgow Coma Scale (GCS) score of 13 to 15, GCS score of 9 to 12 (OR 10.2; 95% CI 4.3 to 24.4) and GCS score of <9 (OR 15.0; 95% CI 7.2 to 31.1), intraventricular hemorrhage (OR 2.4; 95% CI 1.2 to 4.83), skull fractures (OR 3.6; 95% CI 2.0 to 6.6), CT worsening (OR 3.3; 95% CI 1.8 to 5.9), and neurosurgical interventions (OR 3.8; 95% CI 2.1 to 7.0) were significantly associated with ICPM. Restricting to those who met the BTF guidelines, only 43 of 240 (18%) underwent ICPM. Factors independently associated with ICPM included intraparenchymal hemorrhage (OR 2.2; 95% CI 1.0 to 4.7), skull fractures (OR 3.9; 95% CI 1.9 to 8.2), and neurosurgical interventions (OR 3.5; 95% CI 1.7 to 7.2). DISCUSSION: Worsening GCS, intraparenchymal/intraventricular hemorrhage, and skull fractures were associated with ICPM among older adults with TBI, yet utilization of ICPM remains low, especially among those meeting the BTF guidelines, and potential benefits remain unclear. This study highlights the need for better understanding of factors that influence compliance with BTF guidelines and the risks versus benefits of ICPM in this population. LEVEL OF EVIDENCE: Prognostic and epidemiological, level III.

Disparities in triage and management of the homeless and the elderly trauma patient.

BACKGROUND: Trauma systems are designed to provide specialized treatment for the most severely injured. As populations change, it is imperative for trauma centers to remain dynamic to provide the best care to all members of the community. METHODS: A retrospective review of all trauma patients treated at one Level II trauma center in Southern CA over 5 years. Three cohorts of patients were studied: geriatric (> 65 years), the homeless, and all other trauma patients. Triage, hospitalization, and outcomes were collected and analyzed. RESULTS: Of 8431 patients treated, 30% were geriatric, 3% homeless and 67% comprised all other patients. Trauma activation criteria was met for 84% of all other trauma patients, yet only 61% of homeless and geriatric patients combined. Injury mechanism for homeless included falls (38%), pedestrian/bicycle related (27%) and assaults (24%), often while under the influence of alcohol and drugs. Average length of hospital stay (LOS) was greater for homeless and geriatric patients and frequently attributed to discharge planning challenges. Both the homeless and geriatric groups demonstrated increased complications, comorbidities, and death rates. CONCLUSIONS: Homeless trauma patients reflect similar challenges in care as with the elderly, requiring additional resources and more complex case management. It is prudent to identify and understand the issues surrounding patients transported to our trauma center requiring a higher level of care yet are under-triaged upon arrival to the Emergency Department. Although a monthly review is done for all under-triaged patients, and geriatric patients are acknowledged to be a cohort continually having delays, the homeless cohort continues to be under-triaged. The admitted homeless trauma patient has similar complex case management issues as the elderly related to pre-existing health issues and challenges with discharge planning, both which can add to longer lengths of hospital stay as compared to other trauma patients. Given the lack of social support that is endemic to both populations, these cohorts represent a unique challenge to trauma centers. Further research into specialized care is required to determine best practices to address disparities evident in the homeless and elderly, and to promote health equity in marginalized populations.

Falls from a balcony while intoxicated: a new injury trend among young adults?

BACKGROUND: Unintentional falls from heights, including balconies, result in life threatening traumatic injury. Alcohol, when combined with environmental factors and poor judgement, can potentially lead to fatal outcomes. One trauma center's registry identified a group of young adults falling from balconies and we investigated the role of alcohol. METHODS: Hospital trauma service admissions from 2010 through 2017 were reviewed for unintentional falls from heights. Suicide attempts and unintentional falls off ladders or roofs were excluded. Data were obtained from trauma registry and medical record review, as well as social work service interviews. RESULTS: Falls from heights comprised 4.8% of injuries treated at our trauma center during the eight-year study period with 98.5% admitted. Of patients admitted because of falls, 10.3% (55/532) were from a balcony. The majority of this group of patients was male and 19-29 years old (67%). Of patients with a blood alcohol concentration (BAC) determination, 62% had a positive BAC upon hospital admission with an average of 0.20 g/dL among those 34 patients. No gender differences were evident for alcohol use. Seven of the eight patients under the legal drinking age of 21 years were a subgroup with high alcohol use as compared with patients 21 years and older (p = 0.099). Ninety-four percent of falls occurred at residential locations such as dormitories or apartment complexes, often during a social event. Backward falls off railings and attempts to jump to adjoining balconies were common. Head, thorax/abdomen, and extremity fractures were common, with an average injury severity score (ISS) of 16. Average length of hospital stay was 8 days. Most patients (67%) were discharged home after hospital stay, but 21% were transferred to inpatient rehabilitation or skilled nursing facilities. There were two deaths. CONCLUSIONS: Falls from balconies among young adults occur in our area yet the true frequency of these events remain unknown. Occurrence was most common among underage drinkers. Generalization is difficult with this small sample, yet high risk behaviors and environmental factors were evident. It is imperative that educational programs focus on this population with collaborative prevention efforts focused on the dangers of, and increased risk of injury associated with the balcony environment.

Trauma resource designation: an innovative approach to improving trauma system overtriage.

BACKGROUND: Effective triage of injured patients is often a balancing act for trauma systems. As healthcare reimbursements continue to decline,1 innovative programs to effectively use hospital resources are essential in maintaining a viable trauma system. The objective of this pilot intervention was to evaluate a new triage model using 'trauma resource' (TR) as a new category in our existing Tiered Trauma Team Activation (TA) approach with hopes of decreasing charges without adversely affecting patient outcome. METHODS: Patients at one Level II Trauma Center (TC) over seven months were studied. Patients not meeting American College of Surgeons criteria for TA were assigned as TR and transported to a designated TC for expedited emergency department (ED) evaluation. Such patients were immediately assessed by a trauma nurse, ED nurse, and board-certified ED physician. Diagnostic studies were ordered, and the trauma surgeon (TS) was consulted as needed. Demographics, injury mechanism, time to physician evaluation, time to CT scan, time to disposition, hospital length of stay (LOS), and in-hospital mortality were analyzed. RESULTS: Fifty-two of the 318 TR patients were admitted by the TS and were similar to TA patients (N=684) with regard to gender, mean Injury Severity Score, mean LOS and in-hospital mortality, but were older (60.4 vs 47.2 years, p<0.0001) and often involved in a fall injury (52% vs 35%, p=0.0170). TR patients had increased door to physician evaluation times (11.5 vs 0.4 minutes, p<0.0001) and increased door to CT times (76.2 vs 25.9 minutes, p<0.0001). Of the 313 TR patients, 52 incurred charges totaling US$253 708 compared with US$1 041 612 if patients had been classified as TA. CONCLUSIONS: Designating patients as TR prehospital with expedited evaluation by an ED physician and early TS consultation resulted in reduced use of resources and lower hospital charges without increase in LOS, time to disposition or in-hospital mortality. LEVEL OF EVIDENCE: Level II.

Spontaneous Iliac vein rupture: case report and comprehensive review of the literature.

Iliac vein rupture is a rare cause of retroperitoneal hemorrhage. It is occasionally lethal, with no clear precipitating factors. We report a case of spontaneous left common iliac vein rupture in a 56-year-old man with a history of deep vein thrombophlebitis (DVT). To date, 32 cases have been reported in the literature. The 32 existing cases and the case presented here were analyzed. A comparative review was performed for chief complaints, basic demographics, potential predisposing factors, treatment modalities, and outcomes. Possible etiological factors to explain this phenomenon were formulated. The patient presented with abdominal pain of 4 hr duration and a near-syncope episode. In the emergency room, he was found to be in hypovolemic shock that was responsive to crystalloids. An urgent exploratory laparotomy was performed for a suspected iliac artery rupture. An uncontrollable hemorrhage from a spontaneous posteromedial tear of the left common iliac vein resulted in intraoperative death. Interestingly, 85% of reported cases occurred in women with an overall average age of 60.6 +/- 13.4 years; 94% of cases were left-sided; 79% reported clinical or histological evidence of DVT or thrombophlebitis; 94% were treated operatively, with a survival rate of 71%. Only one reported case was treated conservatively, with success, and one reported case of endovascular repair resulted in significant morbidity. Iliac vein rupture is an uncommon diagnosis associated with trauma and even rarer when it is spontaneous. We report the thirty-third documented case in the literature since 1961. There is a clear predominance in females and on the left side and a probable association with thrombophlebitis. Our calculated operative success may be overestimated due to a biased literature reporting of favorable outcomes.
