Network Analysis Examining Intrahospital Traffic of Patients With Traumatic Hip Fracture.

INTRODUCTION: Increased intrahospital traffic (IHT) is associated with adverse events and infections in hospitalized patients. Network science has been used to study patient flow in hospitals but not specifically for patients with traumatic injuries. METHODS: This retrospective analysis included 103 patients with traumatic hip fractures admitted to a level I trauma center between April 2021 and September 2021. Associations with IHTs (moves within the hospital) were analyzed using R (4.1.2) as a weighted directed graph. RESULTS: The median (interquartile range) number of moves was 8 (7-9). The network consisted of 16 distinct units and showed mild disassortativity (-0.35), similar to other IHT networks. The floor and intensive care unit (ICU) were central units in the flow of patients, with the highest degree and betweenness. Patients spent a median of 20-28 hours in the ICU, intermediate care unit, or floor. The number of moves per patient was mildly correlated with hospital length of stay (ρ = 0.26, p = .008). Intrahospital traffic volume was higher on weekdays and during daytime hours. Intrahospital traffic volume was highest in patients aged <65 years ( p = .04), but there was no difference in IHT volume by dependent status, complications, or readmissions. CONCLUSIONS: Network science is a useful tool for trauma patients to plan IHT, flow, and staffing.

Predictors of transfer from a remote trauma facility to an urban level I trauma center for blunt splenic injuries: a retrospective observational multicenter study.

BACKGROUND: The decision-making for admission versus emergent transfer of patients with blunt splenic injuries presenting to remote trauma centers with limited resources remains a challenge. Although splenectomy is standard for hemodynamically unstable patients, the specific criterion for non-operative management continues to be debated. Often, lower-level trauma centers do not have interventional radiology capabilities for splenic artery embolization, leading to transfer to a higher level of a care. Thus, the aim of this study was to identify specific characteristics of patients with blunt splenic injuries used for admittance or transfer at a remote trauma center. METHODS: A retrospective observational study was performed to examine the management of splenic injuries at a mountainous and remote Level III trauma center. Trauma patients ≥ 18 years who had a blunt splenic injury and initially received care at a Level III trauma center prior to admittance or transfer were included. Data were collected over 4.5 years (January 1, 2016 - June 1, 2020). Patients who were transferred out in > 24 h were excluded. Patient demographics, injury severity, spleen radiology findings, and clinical characteristics were compared by decision to admit or transfer to a higher level of care ≤ 24 h of injury. Results were analyzed using chi-square, Fisher's exact, or Wilcoxon tests. Multivariable logistic models were used to identify predictors of transfer. RESULTS: Of the 73 patients included with a blunt splenic injury, 48% were admitted and 52% were transferred to a Level I facility. Most patients were male (n = 58), were a median age of 26 (21-42) years old, most (n = 62) had no comorbidities, and 47 had been injured from a ski/snowboarding accident. Compared to admitted patients, transferred patients were significantly more likely to be female (13/38 vs. 3/36, p = 0.007), to have an abbreviated injury scale score ≥ 3 of the chest (31/38 vs. 7/35, p = 0.002), have a higher injury severity score (16 (16-22) vs. 13 (9-16), p = 0.008), and a splenic injury grade ≥ 3 (32/38 vs. 12/35, p < 0.001). After adjustment, splenic injury grade ≥ 3 was the only predictor of transfer (OR: 12.1, 95% CI: 3.9-37.3, p < 0.001). Of the 32 transfers with grades 3-5, 16 were observed, and 16 had an intervention. Compared to patients who were observed after transfer, significantly more who received an intervention had a blush on CT (1/16 vs. 7/16, p = 0.02) and a higher median spleen grade of 4 (3-5) vs. 3 (3-3.5), p = 0.01). CONCLUSIONS: Our data suggest that most patients transferred from a remote facility had a splenic injury grade ≥ 3, with concomitant injuries but were hemodynamically stable and were successfully managed non-operatively. Stratifying by spleen grade may assist remote trauma centers with refining transfer criteria for solid organ injuries.

An Educational Outreach Program: A Trauma System's 5-Year Experience.

BACKGROUND: The American College of Surgeons Committee on Trauma requires Level I and II trauma centers to provide educational outreach to lower-level facilities. Although outreach is a required part of any trauma system, very little is published on the resources required for a successful program. OBJECTIVE: The purpose of this article is to provide a comprehensive roadmap of the required components to achieve a successful trauma outreach program. METHODS: This project describes the development and implementation of an educational outreach program from January 2016 to December 2020 that has grown from 27 facilities within one western state to 49 facilities across 14 different states. Program components measured include the number and attendance of trauma courses offered, including the Trauma Nursing Core Course (TNCC), Advanced Trauma Life Support (ATLS), Rural Trauma Team Development Course (RTTDC), the number of trauma meetings and webinars provided, total trauma center designation and reviews, total states reached, and total trauma center collaborations. RESULTS: From 2016 to 2020, the program more than doubled the number of TNCC and ATLS courses, maintained the number of RTTDC offered, and observed attendance rate increases of 33% and 11% for TNCC and ATLS courses, respectively. Outreach leadership attended 44 trauma meetings and educational webinars using virtual platform technology, nearly doubling the trauma center outreach with expansion across 14 states resulting in important changes in practice. CONCLUSION: With administrative support, effective leadership, and technology, outreach programs can serve as important resources for statewide trauma systems.

Intravenous Low-Dose Ketamine Provides Greater Pain Control Compared to Fentanyl in a Civilian Prehospital Trauma System: A Propensity Matched Analysis.

Objective: A few studies report comparable analgesic efficacy between low-dose ketamine and opioids such as morphine or fentanyl; however, limited research has explored the safety and effectiveness of intravenous low-dose ketamine as a primary analgesic in a civilian prehospital setting. The objective of this study is to compare pain control between low-dose ketamine and fentanyl when administered intravenously (IV) for the indication of severe pain. Methods: This was a retrospective, observational review of prehospital adult patients (≥18 years) who presented with severe pain (numeric rating scale, 7-10) and were treated solely with either low-dose ketamine IV or fentanyl IV between January 1, 2014 and December 31, 2016. Propensity matched analysis was performed adjusting for all baseline variables with p ≤ 0.10 and for baseline pain score to match ketamine and fentanyl patients on a one-to-one ratio. The primary outcome was change in pain score from baseline to after treatment and evaluated with a paired t-test. Secondary outcomes were changes in vital signs and Glasgow coma scale (GCS) from baseline to after treatment, as well as incidence of clinically significant adverse events (AEs); AEs were followed from scene arrival through emergency department discharge. Results: Propensity matched analysis produced 79 matched pairs. Ketamine IV patients, receiving a mean (SD) dose of 0.3 (0.1) mg/kg, showed a significantly larger mean decrease in pain after treatment, compared to the fentanyl IV patients (-5.5 (3.1) vs. -2.5 (2.4), p < 0.001). A significantly greater proportion of patients receiving ketamine IV achieved at least a 50% reduction in pain compared to those receiving fentanyl IV (67% vs. 19%, p < 0.001), marking 52 ketamine IV patients as responders to treatment. Vital signs demonstrated a nonsignificant decrease in blood pressure, respiratory rate, heart rate, and GCS. No clinically significant AEs were reported for patients receiving ketamine IV. Conclusion: The significant reduction in pain, significantly high proportion of ketamine responders, and the lack of clinically significant AEs characterizing patients receiving low-dose ketamine IV compared to fentanyl IV, all provide further support for its use as an effective prehospital analgesic. Level of Evidence: Level III, therapeutic.

Efficiencies gained by using electronic medical record and reports in trauma documentation.

Despite successful implementation of an electronic medical record (EMR) by many health care organizations, information regarding EMR for trauma resuscitation is limited, and few have created reports that facilitate trauma registry data abstraction, performance improvement reviews, and provider care requirements. In October 2010, our organization implemented an EMR for trauma resuscitations. A collaborative committee was formed to standardize data elements. Documentation compliance was monitored pre- and post-EMR implementation. Median monthly documentation completion improved from 82% to a sustained median score of 96.5% for the past 603 activations. Documentation compliance enabled the development of succinct reports that facilitate our internal needs and supported our trauma center reverification site visit.

Management of pediatric blunt splenic injury at a rural trauma center.

BACKGROUND: Patterns for nonoperative management of pediatric blunt splenic injuries (BSIs) vary significantly within and between institutions. The indications for repeated imaging, duration of activity restrictions, as well as the impact of volume and type of trauma center (pediatric vs. adult) on outcomes remain unclear. METHODS: A retrospective review of all patients younger than 16 years with BSI managed at a rural American College of Surgeons-verified adult Level II trauma center from January 1995 to December 2008 was completed. Patients were identified from the trauma registry by DRG International Classification of Diseases-9th Rev. (865.00-865.09) and management codes (41.5, 41.43, and 41.95). Variables reviewed included demographics, mechanism of injury, Injury Severity Score, grade of splenic injury, degree of hemoperitoneum, presence of arterial phase contrast blush on computed tomography at admission, admission and nadir hemoglobin level, blood transfused, length of stay, disposition, outpatient clinical and radiographic follow-up, interval of return to unrestricted activity, and clinical outcomes. RESULTS: During the 13-year study period, 38 children with BSI were identified. Thirty-seven (97%) were successfully managed nonoperatively. Median grade of splenic injury was 3 (range, 1-5); 73% had moderate-to-large hemoperitoneum. Median Injury Severity Score was 10 (range, 4-34). Three patients with isolated contrast blush on initial computed tomography were successfully managed nonoperatively with no angiographic intervention. One patient failed nonoperative management and underwent successful splenorrhaphy. All patients were discharged home. Thirty-day mortality was zero. Median follow-up duration was 5.5 years, with no late complications identified. Of the patients successfully managed nonoperatively, 92% had their follow-up at our institution; 74% underwent subsequent imaging, and none resulted in intervention or alteration of management plan. CONCLUSION: Pediatric BSI can be managed in adult trauma centers with success rates of nonoperative management comparable to dedicated children's hospitals. Routine follow-up imaging is not necessary. Overall splenic injury salvage rate in our experience was 100%. LEVEL OF EVIDENCE: Therapeutic/epidemiologic study, level IV.
