An initiative to assess and improve the resources and patient care processes used among Chest Wall Injury Society collaborative centers study (CWIS-CC2).

BACKGROUND: Over the last two decades, the acute management of rib fractures has changed significantly. In 2021, the Chest Wall injury Society (CWIS) began recognizing centers that epitomize their mission as CWIS Collaborative Centers. The primary aim of this study was to determine the resources, surgical expertise, access to care, and institutional support that are present among centers. METHODS: A survey was performed including all CWIS Collaborative Centers evaluating the resources available at their hospital for the treatment of patients with chest wall injury. Data about each chest wall injury center care process, availability of resources, institutional support, research support, and educational offerings were recorded. RESULTS: Data were collected from 20 trauma centers resulting in an 80% response rate. These trauma centers were made up of 5 international and 15 US-based trauma centers. Eighty percent (16 of 20) have dedicated care team members for the evaluation and management of rib fractures. Twenty-five percent (5 of 20) have a dedicated rib fracture service with a separate call schedule. Staffing for chest wall injury clinics consists of a multidisciplinary team: with attending surgeons in all clinics, 80% (8 of 10) with advanced practice providers and 70% (7 of 10) with care coordinators. Forty percent (8 of 20) of centers have dedicated rib fracture research support, and 35% (7 of 20) have surgical stabilization of rib fracture (SSRF)-related grants. Forty percent (8 of 20) of centers have marketing support, and 30% (8 of 20) have a web page support to bring awareness to their center. At these trauma centers, a median of 4 (1-9) surgeons perform SSRFs. In the majority of trauma centers, the trauma surgeons perform SSRF. CONCLUSION: Considerable similarities and differences exist within these CWIS collaborative centers. These differences in resources are hypothesis generating in determining the optimal chest wall injury center. These findings may generate several patient care and team process questions to optimize patient care, patient experience, provider satisfaction, research productivity, education, and outreach.

Characterizing re-triage guidelines: A scoping review of states' rules and regulations.

BACKGROUND: State guidelines for re-triage, or emergency inter-facility transfer, have never been characterized across the United States. METHODS: All 50 states' Department of Health and/or Trauma System websites were reviewed for publicly available re-triage guidelines within their rules and regulations. Communication was made via phone or email to state agencies or trauma advisory committees to obtain or confirm the absence of guidelines where public data was unavailable. Guideline criteria were abstracted and grouped into domains of Center for Disease Control Field Triage Criteria: pattern/anatomy of injury, vital signs, special populations, and mechanisms of injury. Re-triage criteria were summarized across states using median and interquartile ranges for continuous data and frequencies for categorical data. Demographic data of states with and without re-triage guidelines were compared using the Wilcoxon rank sum test. RESULTS: Re-triage guidelines were identified for 22 of 50 states (44%). Common anatomy of injury criteria included head trauma (91% of states with guidelines), spinal cord injury (82%), chest injury (77%), and pelvic injury (73%). Common vital signs criteria included Glasgow Coma Score (91% of states) ranging from 8 to 14, systolic blood pressure (36%) ranging from 90 to 100 mm Hg, and respiratory rate (23%) with all using 10 respirations/minute. Common special populations criteria included mechanical ventilation (73% of states), age (68%) ranging from <2 or >60 years, cardiac disease (59%), and pregnancy (55%). No significant demographic differences were found between states with versus without re-triage guidelines. CONCLUSION: A minority of US states have re-triage guidelines. Characterizing existing criteria can inform future guideline development.

Safety and efficacy of fixed versus variable-dose prothrombin complex concentrate for emergent reversal of vitamin K antagonists: A systematic review and meta-analysis.

STUDY OBJECTIVE: Four-factor prothrombin complex concentrate (4F-PCC) is standard of care for emergent vitamin K antagonist (VKA) reversal but optimal dosing is uncertain. This meta-analysis estimated the proportion of patients treated with fixed dose (FD) 4F-PCC who achieved adequate reversal and compared safety and efficacy of FD versus weight-based dose (WB) strategies. METHODS: This review was conducted according to PRISMA guidelines. Medline and Scopus were searched and included studies evaluating FD regimens and comparing FD and WB for emergent VKA reversal. Data was pooled using random effects. Subgroup analyses examined heterogeneity. Risk of bias was assessed with Newcastle-Ottawa Scale and RoB2 score. RESULTS: Twenty-three studies (n = 2055) were included with twelve (n = 1143) comparing FD versus WB. The proportion of patients achieving goal INR with FD varied depending on the INR target, being significantly higher for INR <2 (90.9%, 95% Confidence Interval (CI) 87.2, 94.06) compared to INR <1.6 (70.97%, 95%CI 65.33, 76.31). Compared to WB, FD was less likely to achieve a goal INR <1.6 (Risk Difference (RD) -13%, 95% CI -21, -4) but achieved similar reversal for a goal INR <2.0, (RD -1%, 95%CI -7, 4). There was no difference in hospital mortality (RD 4%, 95%CI -2, 9) or thrombosis (RD 0.0%, 95%CI -3, 3). CONCLUSION: FD VKA reversal was associated with significantly lower attainment of goal INR compared to WB with lower INR targets. This did not translate to differences in hospital mortality, but these results should be interpreted cautiously in light of the observational nature of the included studies.

Rib fixation for flail chest physiology and the facilitation of safe prone spinal surgery: illustrative case.

BACKGROUND: Spine fractures are frequently associated with additional injuries in the trauma setting, with chest wall trauma being particularly common. Limited literature exists on the management of flail chest physiology with concurrent unstable spinal injury. The authors present a case in which flail chest physiology precluded safe prone surgery and after rib fixation the patient tolerated spinal fixation without further issue. OBSERVATIONS: Flail chest physiology can cause cardiovascular decompensation in the prone position. Stabilization of the chest wall addresses this instability allowing for safe prone spinal surgery. LESSONS: Chest wall fixation should be considered in select cases of flail chest physiology prior to stabilization of the spinal column in the prone position. Further research is necessary to identify patients that are at highest risk to not tolerate prone surgery.

The evolution of a chest wall injury and reconstruction clinic during a pandemic.

BACKGROUND: In 2019, we sought to develop a chest wall injury and reconstruction clinic (CWIRC) to treat patients with chest wall pain and rib fractures. This initiative was fueled by the recognition of an unmet need and evolving research demonstrating improved patient care and experience. We will describe the evolution of this clinic program from an acute care surgery/general surgery (ACS/GS) clinic to a CWIRC. METHODS: We identified outpatient encounters generated from a general surgery clinic staffed by a physician and nurse practitioner team. A retrospective cohort review was performed to identify all outpatient encounters and surgeries associated with these encounters from January 1, 2017, to November 30, 2021. Outpatient and operative work relative value unit (wRVU) production as well as payer mix was compared as the primary outcome. RESULTS: Over this time period, the number of clinic interactions decreased (2017-284 vs. 2021-229). Clinic productivity increased however from 181 wRVUs in 2017 to 295 wRVUs in 2021. The CWIRC patient visits increased from 4% to 70%. In addition, telehealth visits increased from 0% to 23% of encounters. The operative wRVU productivity attributable to outpatient clinic visits increased (2017-253 vs. 2021-591). Combined, the CWIRC resulted in an overall growth of 104% in total wRVUs. The payer mixes for patients with rib diagnosis have a higher number of Blue Cross Blue Shield, Medicare, and Managed Care compared with ACS/GS. The most common diagnosis was rib fracture initial evaluation (37%), rib fracture subsequent encounter (25%), rib pain (24%), and flail chest initial evaluation (4%). CONCLUSION: The initiation of a CWIRC increased wRVU production despite a decrease in clinical encounters. These clinics may produce more wRVUs per encounter than ACS/GS clinics. An underserved population has been identified of chest wall pathology patients presenting for initial evaluation as outpatients. Further investigation into this concept is warranted to serve this population. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Surgical stabilization of rib fractures versus nonoperative treatment in patients with multiple rib fractures following cardiopulmonary resuscitation: An international, retrospective matched case-control study.

BACKGROUND: The presence of six or more rib fractures or a displaced rib fracture due to cardiopulmonary resuscitation (CPR) has been associated with longer hospital and intensive care unit (ICU) length of stay (LOS). Evidence on the effect of surgical stabilization of rib fractures (SSRF) following CPR is limited. This study aimed to evaluate outcomes after SSRF versus nonoperative management in patients with multiple rib fractures after CPR. METHODS: An international, retrospective study was performed in patients who underwent SSRF or nonoperative management for multiple rib fractures following CPR between January 1, 2012, and July 31, 2020. Patients who underwent SSRF were matched to nonoperative controls by cardiac arrest location and cause, rib fracture pattern, and age. The primary outcome was ICU LOS. RESULTS: Thirty-nine operatively treated patient were matched to 66 nonoperatively managed controls with comparable CPR-related characteristics. Patients who underwent SSRF more often had displaced rib fractures (n = 28 [72%] vs. n = 31 [47%]; p = 0.015) and a higher median number of displaced ribs (2 [P 25 -P 75 , 0-3] vs. 0 [P 25 -P 75 , 0-3]; p = 0.014). Surgical stabilization of rib fractures was performed at a median of 5 days (P 25 -P 75 , 3-8 days) after CPR. In the nonoperative group, a rib fixation specialist was consulted in 14 patients (21%). The ICU LOS was longer in the SSRF group (13 days [P 25 -P 75 , 9-23 days] vs. 9 days [P 25 -P 75 , 5-15 days]; p = 0.004). Mechanical ventilator-free days, hospital LOS, thoracic complications, and mortality were similar. CONCLUSION: Despite matching, those who underwent SSRF over nonoperative management for multiple rib fractures following CPR had more severe consequential chest wall injury and a longer ICU LOS. A benefit of SSRF on in-hospital outcomes could not be demonstrated. A low consultation rate for rib fixation in the nonoperative group indicates that the consideration to perform SSRF in this population might be associated with other nonradiographic or injury-related variables.

Surgical stabilization versus nonoperative treatment for flail and non-flail rib fracture patterns in patients with traumatic brain injury.

PURPOSE: Literature on outcomes after SSRF, stratified for rib fracture pattern is scarce in patients with moderate to severe traumatic brain injury (TBI; Glasgow Coma Scale ≤ 12). We hypothesized that SSRF is associated with improved outcomes as compared to nonoperative management without hampering neurological recovery in these patients. METHODS: A post hoc subgroup analysis of the multicenter, retrospective CWIS-TBI study was performed in patients with TBI and stratified by having sustained a non-flail fracture pattern or flail chest between January 1, 2012 and July 31, 2019. The primary outcome was mechanical ventilation-free days and secondary outcomes were in-hospital outcomes. In multivariable analysis, outcomes were assessed, stratified for rib fracture pattern. RESULTS: In total, 449 patients were analyzed. In patients with a non-flail fracture pattern, 25 of 228 (11.0%) underwent SSRF and in patients with a flail chest, 86 of 221 (38.9%). In multivariable analysis, ventilator-free days were similar in both treatment groups. For patients with a non-flail fracture pattern, the odds of pneumonia were significantly lower after SSRF (odds ratio 0.29; 95% CI 0.11-0.77; p = 0.013). In patients with a flail chest, the ICU LOS was significantly shorter in the SSRF group (beta, - 2.96 days; 95% CI - 5.70 to - 0.23; p = 0.034). CONCLUSION: In patients with TBI and a non-flail fracture pattern, SSRF was associated with a reduced pneumonia risk. In patients with TBI and a flail chest, a shorter ICU LOS was observed in the SSRF group. In both groups, SSRF was safe and did not hamper neurological recovery.

Surgical stabilization of severe chest wall injury following cardiopulmonary resuscitation.

BACKGROUND: Cardiopulmonary resuscitation (CPR) contributes to significant chest wall injury similar to blunt trauma. With benefits realized for surgical stabilization of rib fractures (SSRFs) for flail injuries and severely displaced fractures following trauma, SSRF for chest wall injury following CPR could be advantageous, provided good functional and neurologic outlook. Experience is limited. We present a review of patients treated with SSRF at our institution following CPR. METHODS: A retrospective analysis of patients undergoing SSRF following CPR was performed between 2019 and 2020. Perioperative inpatient data were collected with outpatient follow-up as able. RESULTS: Five patients underwent SSRF over the course of the 2-year interval. All patients required invasive ventilation preoperatively or had impending respiratory. Mean age was 59 ± 12 years, with all patients being male. Inciting events for cardiac arrest included respiratory, ventricular tachycardia, ventricular fibrillation, pulseless electrical activity, and anaphylaxis. Time to operation was 6.6 ± 3 days. Four patients demonstrated anterior flail injury pattern with or without sternal fracture, with one patient having multiple severely displaced fractures. Surgical stabilization of rib fracture was performed appropriately to restore chest wall stability. Mean intensive care unit length of stay was 9.8 ± 6.4 days and overall hospital length of stay 24.6 ± 13.2 days. Median postoperative ventilation was 2 days (range, 1-15 days) with two patients developing pneumonia and one requiring tracheostomy. There were no mortalities at 30 days. One patient expired in hospice after a prolonged hospitalization. Disposition destination was variable. No hardware complications were noted on outpatient follow-up, and all surviving patients were home. CONCLUSION: Chest wall injuries are incurred frequently following CPR. Surgical stabilization of these injuries can be considered to promote ventilator liberation and rehabilitation. Careful patient selection is paramount, with surgery offered to those with reversible causes of arrest and good functional and neurologic outcome. Experience is early, with further investigation needed. LEVEL OF EVIDENCE: Therapeutic, Level V.

Decreased Incidence of Rib Fractures in Pregnant Patients After Motor Vehicle Collisions.

BACKGROUND: Rib fractures are common after motor vehicle collisions. The hormonal changes associated with pregnancy decrease the stiffness and increase the laxity of cartilage and tendons. The effect of these changes on injury mechanics is not completely understood. OBJECTIVES: To compare the incidences of chest wall injury following blunt thoracic trauma between pregnant and nonpregnant women. METHODS: The authors conducted a retrospective review of female patients seen at a level I trauma center from 2009 to 2017 after a motor vehicle collision. Patient characteristics were compared to determine if pregnancy affected the incidence of chest wall injury. Statistics were calculated with SPSS version 24 and are presented as mean (SD) or median (interquartile range). RESULTS: In total, 1618 patients were identified. The incidence of rib/sternal fracture was significantly lower in pregnant patients (7.9% vs 15.2%, P = .047), but the incidence of intrathoracic injury was similar between the groups. Pregnant and nonpregnant patients with rib/sternal fractures had similar Injury Severity Score results (21 [13-27] vs 17 [11-22], P = .36), but pregnant patients without fractures had significantly lower scores (1 [0-5] vs 4 [1-9], P < .001). CONCLUSIONS: Pregnant patients have a lower rate of rib fracture after a motor vehicle collision than nonpregnant patients. The difference in injury mechanics may be due to hormonal changes that increase elasticity and resistance to bony injury of the ribs. In pregnant trauma patients, intrathoracic injury without rib fracture should raise concerns about injury severity. A multicenter evaluation of these findings is needed.

Cardiopulmonary Resuscitation-Induced Hardware Failure After Surgical Stabilization of Flail Chest.

Flail chest occurs when three or more ribs have concurrent fractures in two or more places. Flail chest is a marker of injury severity and is associated with increased morbidity and mortality. The management of flail chest includes multiple nonoperative components in addition to surgical stabilization, which has been shown to lower mortality rates to those of multiple rib fractures with a stable chest wall (i.e., no flail chest). The resulting stability of the chest wall may be a more accurate prognostic indicator than the actual number of ribs fractured. Surgical stabilization has been associated with various complications. The overall incidence of hardware failure is relatively rare and often involves the anterolateral and lateral regions of the chest wall. We present a unique case of a 48-year-old male involved in a motor vehicle accident with multiple traumatic injuries, including flail chest. He ultimately underwent surgical stabilization across six separate ribs in nine total locations. The patient's condition deteriorated several weeks later, and he required cardiopulmonary resuscitation. High impact forces caused hardware failure in three separate locations along the chest wall, i.e., anteriorly, anterolaterally, and posterolaterally. The most significant failure occurred anteriorly with sternal plate and screw separation. We suspect that hardware failure in the anterior and anterolateral regions indicates that the sternum and costochondral junction may be dynamic areas of the chest wall that dissipate forces differently than do the bone of ribs.

Major publications in the critical care pharmacotherapy literature: 2019.

PURPOSE: To summarize selected meta-analyses and trials related to critical care pharmacotherapy published in 2019. MATERIALS AND METHODS: The Critical Care Pharmacotherapy Literature Update (CCPLU) Group screened 36 journals monthly for impactful articles and reviewed 113 articles during 2019 according to Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) criteria. RESULTS: Articles with a 1A grade, including three clinical practice guidelines, six meta-analyses, and five original research trials are reviewed here from those included in the monthly CCPLU. Clinical practice guidelines on the use of polymyxins and antiarrhythmic drugs in cardiac arrest as well as meta-analyses on antipsychotic use in delirium, stress ulcer prophylaxis (SUP), and vasoactive medications in septic shock and cardiac arrest were summarized. Original research trials evaluated delirium, sedation, neuromuscular blockade, SUP, anticoagulation reversal, and hemostasis. CONCLUSION: This clinical review and expert opinion provides summary and perspectives of clinical practice impact on influential critical care pharmacotherapy publications in 2019.

Outcome after surgical stabilization of rib fractures versus nonoperative treatment in patients with multiple rib fractures and moderate to severe traumatic brain injury (CWIS-TBI).

BACKGROUND: Outcomes after surgical stabilization of rib fractures (SSRF) have not been studied in patients with multiple rib fractures and traumatic brain injury (TBI). We hypothesized that SSRF, as compared with nonoperative management, is associated with favorable outcomes in patients with TBI. METHODS: A multicenter, retrospective cohort study was performed in patients with rib fractures and TBI between January 2012 and July 2019. Patients who underwent SSRF were compared to those managed nonoperatively. The primary outcome was mechanical ventilation-free days. Secondary outcomes were intensive care unit length of stay and hospital length of stay, tracheostomy, occurrence of complications, neurologic outcome, and mortality. Patients were further stratified into moderate (GCS score, 9-12) and severe (GCS score, ≤8) TBI. RESULTS: The study cohort consisted of 456 patients of which 111 (24.3%) underwent SSRF. The SSRF was performed at a median of 3 days, and SSRF-related complication rate was 3.6%. In multivariable analyses, there was no difference in mechanical ventilation-free days between the SSRF and nonoperative groups. The odds of developing pneumonia (odds ratio [OR], 0.59; 95% confidence interval [95% CI], 0.38-0.98; p = 0.043) and 30-day mortality (OR, 0.32; 95% CI, 0.11-0.91; p = 0.032) were significantly lower in the SSRF group. Patients with moderate TBI had similar outcome in both groups. In patients with severe TBI, the odds of 30-day mortality was significantly lower after SSRF (OR, 0.19; 95% CI, 0.04-0.88; p = 0.034). CONCLUSION: In patients with multiple rib fractures and TBI, the mechanical ventilation-free days did not differ between the two treatment groups. In addition, SSRF was associated with a significantly lower risk of pneumonia and 30-day mortality. In patients with moderate TBI, outcome was similar. In patients with severe TBI a lower 30-day mortality was observed. There was a low SSRF-related complication risk. These data suggest a potential role for SSRF in select patients with TBI. LEVEL OF EVIDENCE: Therapeutic, level IV.

Efficacy of Methocarbamol for Acute Pain Management in Young Adults With Traumatic Rib Fractures.

BACKGROUND: Rib fractures account for more than one-third of blunt thoracic injuries and are associated with serious complications. Use of nonopioid adjunctive agents such as methocarbamol for pain control has increased considerably. OBJECTIVE: This study aimed to assess the impact of methocarbamol addition to the pain control regimen on daily opioid requirements for young adults with rib fractures. METHODS: This observational, retrospective study included patients aged 18 to 39 years with 3 or more rib fractures who were admitted to a level 1 trauma center between July 2014 and July 2018. Patients were dichotomized based on admission before and after methocarbamol addition to the institutional rib fracture protocol. The primary outcome was to determine the impact of methocarbamol on daily opioid requirements. Secondary outcomes included hospital length of stay (LOS) and diagnosis of pneumonia. RESULTS: A total of 50 patients were included, with 22 and 28 patients in the preprotocol and postprotocol groups, respectively. All patients in the latter group received methocarbamol, whereas no patient in the preprotocol group received methocarbamol. Cumulative opioid exposure was significantly less for patients admitted after methocarbamol addition to the protocol (219 vs 337 mg oral morphine equivalents; P = 0.01), and hospital LOS was also decreased (4 vs 3 days; P = 0.03). No significant differences in the incidence of pneumonia or adverse effects were observed. CONCLUSION AND RELEVANCE: This is the first study to evaluate the impact of methocarbamol on reducing opioid requirements. Given the risks associated with opioids, use of methocarbamol as an analgesia-optimizing, opioid-sparing multimodal agent may be reasonable.

Stability of Surgical Rib Fixation Hardware after Repeat Chest Trauma.

Surgical management of rib fractures has long been a controversial topic, but improvements in rib plating technology have led to a recent increase in interest among surgeons. Unfortunately, follow-up data are limited in patients following rib fracture plating. We present a unique case of an adult male who had multiple ribs plated for symptomatic rib fracture nonunions and developed periprosthetic fractures following repeat trauma several months later. A 57-year-old male with a history of trauma was treated for symptomatic nonunion of several left lateral ribs with surgical rib fixation. He tolerated the procedure well and had significant improvement in his symptoms on follow-up. Several months later, he was hit by a motor vehicle while riding his bicycle. He was found to have flail chest with lateral segmental rib fractures of the first through second ribs, posterior periprosthetic fractures of the seventh through tenth ribs, and lateral fractures of the eleventh and twelfth ribs. The rib plating hardware was completely intact, except for a single displaced seventh rib screw. To our knowledge, this is the first case report of repeat chest trauma following rib plating. Interestingly, the patient developed posterior periprosthetic fractures, and hardware was completely intact except for a single screw that was displaced. The goal of this report is to describe the unique fracture pattern of a flail chest with prior rib plating and to describe potential revision plating techniques and complications that surgeons may encounter in the management of trauma patients with prior rib plating.

Risk of ventriculoperitoneal shunt infection with coexisting percutaneous endoscopic gastrostomy tube and associated factors.

OBJECTIVES: Percutaneous endoscopic gastrostomy (PEG) tubes and ventriculoperitoneal shunts (VPS) are commonly placed in neurologically impaired patients. There is concern about safety of VPS coexisting with PEG tubes due to the potential for an increased risk of infection. In this study, we assess the risk of VPS infection and the amount of time between both procedures. PATIENTS AND METHODS: Retrospective chart review of patients from our institution who had VPS and PEG tubes placed during the same hospitalization between 2014 and 2018. Our primary focus was assessing risk of VPS infection and timing of procedures in this patient population. Additionally, we assessed other factors which may contribute to VPS infection including SIRS criteria at time of VPS placement, comorbidities and other procedures performed. None of the SIRS factors were associated with VPS infection. RESULTS: 45 patients met inclusion criteria. Our VPS infection rate was found to be 7% (n = 3). These patients had 4, 16, and 36 days between procedures. 89% of our patients had PEG tube placed prior to VPS with 2 of these patients developing a VPS infection. At the time of VPS placement 42% of patients had SIRS. None of the SIRS factors were associated with VPS infection. CONCLUSION: Our VPS infection rate remained low even when they were performed during the same hospitalization as a PEG tube placement. SIRS is not associated with the development of VPS infections and is not an absolute contraindication to placing a VPS.

A multicenter, prospective, controlled clinical trial of surgical stabilization of rib fractures in patients with severe, nonflail fracture patterns (Chest Wall Injury Society NONFLAIL).

BACKGROUND: The efficacy of surgical stabilization of rib fracture (SSRF) in patients without flail chest has not been studied specifically. We hypothesized that SSRF improves outcomes among patients with displaced rib fractures in the absence of flail chest. METHODS: Multicenter, prospective, controlled, clinical trial (12 centers) comparing SSRF within 72 hours to medical management. Inclusion criteria were three or more ipsilateral, severely displaced rib fractures without flail chest. The trial involved both randomized and observational arms at patient discretion. The primary outcome was the numeric pain score (NPS) at 2-week follow-up. Narcotic consumption, spirometry, pulmonary function tests, pleural space complications (tube thoracostomy or surgery for retained hemothorax or empyema >24 hours from admission) and both overall and respiratory disability-related quality of life (RD-QoL) were also compared. RESULTS: One hundred ten subjects were enrolled. There were no significant differences between subjects who selected randomization (n = 23) versus observation (n = 87); these groups were combined for all analyses. Of the 110 subjects, 51 (46.4%) underwent SSRF. There were no significant baseline differences between the operative and nonoperative groups. At 2-week follow-up, the NPS was significantly lower in the operative, as compared with the nonoperative group (2.9 vs. 4.5, p < 0.01), and RD-QoL was significantly improved (disability score, 21 vs. 25, p = 0.03). Narcotic consumption also trended toward being lower in the operative, as compared with the nonoperative group (0.5 vs. 1.2 narcotic equivalents, p = 0.05). During the index admission, pleural space complications were significantly lower in the operative, as compared with the nonoperative group (0% vs. 10.2%, p = 0.02). CONCLUSION: In this clinical trial, SSRF performed within 72 hours improved the primary outcome of NPS at 2-week follow-up among patients with three or more displaced fractures in the absence of flail chest. These data support the role of SSRF in patients without flail chest. LEVEL OF EVIDENCE: Therapeutic, level II.

Delayed Intracranial Hemorrhage in Anticoagulated Geriatric Patients After Ground Level Falls.

BACKGROUND: The reported risk of delayed intracranial hemorrhage (ICH) in a trauma patient on warfarin is estimated to be between 0.6% and 6%. The risk of delayed ICH in trauma patients taking novel oral anticoagulants (NOACs) is not well-defined. OBJECTIVE: We hypothesized that there was a significant number of delayed presentations of ICH in patients on NOACs. METHODS: A retrospective review of our trauma registry was performed on geriatric patients (age older than 64 years) who were initially evaluated at our level I trauma center, had fall from standing height or less, and were anticoagulated (warfarin or NOACs), from April 2017 to March 2018. RESULTS: Seventy-seven patients met inclusion criteria. The mean age was 80 ± 7.7 years and 46% of patients were male. The admission head computed tomography scan was positive in 20.8% of patients. Positive scans were more common in patients on warfarin vs. NOACs (30% vs. 14%; p = 0.074) and had a significantly higher Injury Severity Score (median [interquartile range]: 9 [3-15] vs. 5 [1-9]; p = 0.030) and Abbreviated Injury Scale-Head score (median [interquartile range]: 1 [0-3] vs. 1 [0-2]; p = 0.035). The agreement between loss of consciousness (LOC) and ICH was 72% (κ = -0.064; p = 0.263). Fifty-one percent of patients had a repeat head CT. New ICH was diagnosed in 9.6% of patients. All of these patients were on NOACs. CONCLUSIONS: A fall from standing or less in anticoagulated geriatric patients is a significant mechanism of injury resulting in ICH. The absence of LOC does not eliminate the possibility of ICH. There is a significant risk of delayed ICH for patients on NOACs and repeat evaluations should be performed. A prospective multicenter evaluation of this finding is warranted.
