The Impact of Resident Involvement on Outcomes and Costs in Elective Hand and Upper Extremity Surgery.

PURPOSE: The purpose of this study was to assess the impact of resident involvement on periprocedural outcomes and costs after common procedures performed at an academic hand surgical practice. METHODS: A retrospective review was performed in all patients undergoing 7 common elective upper extremity procedures between January 2008 and December 2018: carpal tunnel release, distal radius open reduction and internal fixation (ORIF), trigger finger release, thumb carpometacarpal arthroplasty, phalanx closed reduction and percutaneous pinning, cubital tunnel release, and olecranon ORIF. The medical record was reviewed to determine the impact of surgical assistants (resident, fellow, or physician assistant) on periprocedural outcomes, periprocedural costs, and 1-year postoperative outcomes. The involvement of surgical trainees operating under direct supervision was compared with the entire operation performed by the attending surgeon with a physician assistant present. RESULTS: A total of 396 procedures met the inclusion criteria. Analysis of the whole study sample revealed low rates of intraoperative complications, wound complications, medical complications, readmissions, and mortality. Subgroup analysis of carpal tunnel releases revealed significantly greater tourniquet times for residents compared with physician assistants (7 ± 2 min, 6 ± 1 min), as well as longer overall operating room times for residents compared to fellows or physician assistants (17 ± 5 min, 13 ± 3 min, 12 ± 3 min). Operating room times for distal radius ORIF were significantly greater among residents compared to fellows or physician assistants (68 ± 19 min, 57 ± 17 min, 56 ± 14 min). There were no differences in any other perioperative metrics or periprocedural costs for the trigger finger release or cubital tunnel release cohorts. CONCLUSIONS: Resident involvement in select upper extremity procedures can lengthen operative times but does not have an impact on blood loss or operating room costs. CLINICAL RELEVANCE: Surgeons should be aware that having a resident assistant slightly increases operative times in elective hand surgery.

Routine incorporation of longer-term patient-reported outcomes into a Dutch trauma registry.

PURPOSE: Routine collection of post-discharge patient-reported outcomes within trauma registries can be used to benchmark quality of trauma care. This process is dependent on geographic and cultural context, but results are lacking regarding the European experience. We aimed to investigate the feasibility of routine inclusion of longer-term patient-reported health-related quality of life (HRQoL) in a Dutch National Trauma Database (DNTD) and to characterize these outcomes in a prospective cohort study. METHODS: All adult patients (≥ 18 years) who presented for traumatic injury in 2015-2016 and met the inclusion criteria of the DNTD were included. Inclusion criteria of the DNTD are presence of traumatic injury, hospital presentation within 48 h from trauma and hospital admission for treatment of traumatic injury or immediate mortality from traumatic injury after presentation. Exclusion criteria were death, mental impairment, insufficient command of Dutch language and residency outside the Netherlands. Primary outcomes were process-related measures of feasibility (response rate, response methods and reasons for non-response). Secondary outcomes were HRQoL measures [EuroQOL 5-Dimensions 3-Level (EQ-5D-3L) with added cognitive dimension and Visual Analogue Scale (EQ-VAS)]. RESULTS: 2025 unique patients met the initial inclusion criteria, with 1753 patients eligible for follow-up. Of these, 1315 patients participated (response rate 75%). The majority of questionnaires, 990 (75%), were completed on paper, with an additional 325 (25%) through telephone interviews. Primary reason for non-response was lack of contact information (245/438 non-responders; 56%). Median EQ-5D score was 0.81 (IQR 0.68-1.00) (mean 0.74; SD 0.31) and median EQ-VAS score was 78 (IQR 65-90). Compared to a Dutch reference population (mean EQ-5D = 0.87), EQ-5D scores were significantly lower (p < 0.001). CONCLUSIONS: Routine collection of HRQoL is feasible within European health systems, like in the Netherlands. Further integration of these measures into trauma registries may aid worldwide benchmarking of trauma care quality.

Treatment of a Scientifically Neglected Ankle Injury: The Isolated Medial Malleolar Fracture. A Systematic Review.

Isolated medial malleolar fractures are frequently encountered injuries. Literature regarding their treatment, though, is scarce and contradicting. The aim of this systematic review is to compare surgical and conservative treatment of isolated medial malleolar fractures considering complication rates and functional outcomes. PubMed, Embase, Cochrane, and CINAHL were searched for this review. Articles from 1980 or later, written in English, French, German, or Dutch, reporting any outcome of 10 or more isolated medial malleolar fractures in skeletally mature patients were included. Study quality was assessed using the Methodological Index for Non Randomized Studies (MINORS) instrument. Eighteen studies were included involving 2566 isolated medial malleolar fractures, which showed a mean (± SD) MINORS score of 8 ± 2. Mean nonunion rate was 1.7% after surgical treatment and 3.5% after conservative treatment. Overall, comparable functional outcomes were found after both treatment methods. Only 2 of the included studies reported the exact amount of fracture displacement. One study-comparing surgical and conservative treatment-showed similar functional outcomes for 1- and 2-mm displaced isolated medial malleolar fractures, and the other, a nonunion rate of 3.5% and a good mean functional outcome in 57 conservatively treated isolated medial malleolar fractures with a mean displacement of 3.8 mm. The available evidence is scarce and of low quality but suggests that conservative treatment of isolated medial malleolar fractures displaced ≤2 mm is safe. No study exists that compares surgical and conservative treatment in isolated medial malleolar fractures displaced >2 mm. Therefore, further research is needed. Until then, the eventual choice of treatment for isolated medial malleolar fractures displaced >2 mm, might be mainly dependent on the patients' characteristics and demands.

Ankle Fracture Classification: An Innovative System for Describing Ankle Fractures.

A good classification system is important for clinical handoffs, research, and clinical treatment guidelines. A reliable classification system shows good interobserver and intraobserver agreement. This study analyzed the interobserver and intraobserver agreement of a descriptive system for ankle fractures and the Lauge-Hansen classification. Three groups of observers (experts, semiexperts, and novices) scored a total of 20 ankle radiographs. All ankle radiographs were classified according to the Lauge-Hansen and Danis-Weber classifications. The ankle fractures were subsequently reviewed in a descriptive manner for the following features: number of affected malleoli, type of fracture of the lateral and medial malleolus, and congruence of the ankle joint. After 2 weeks, the same set of radiographs were reviewed. For interobserver and intraobserver variability, the separate groups were used for analysis, and the Fleiss (multirater) κ values were calculated. The interobserver agreement for the Lauge-Hansen classification was moderate for the experts, fair for semiexperts, and slight for novices (κ = 0.45, κ = 0.37, and κ = 0.16). All factors of the descriptive system had better interobserver agreement than the Lauge-Hansen classification, except for the agreement on the type of fracture of the lateral malleolus. The intraobserver agreement of the Lauge-Hansen classification was substantial for the experts, moderate for the semiexperts, and fair for the novice observers (κ = 0.70, κ = 0.49, and κ = 0.26). The intraobserver agreement was better for all factors of the descriptive system compared with the Lauge-Hansen classification. The descriptive system presented in this study shows less variability between observers than the Lauge-Hansen classification. This system has clinical implications and is easy to use for clinicians with mixed levels of experience. It has the potential to improve clinical and research handoffs and overcome the limitations of current classification systems.

Surgical treatment of Neer type II and type V lateral clavicular fractures: comparison of hook plate versus superior plate with lateral extension: a retrospective cohort study.

PURPOSE: Different fixation methods are used for treatment of unstable lateral clavicle fractures (LCF). Definitive consensus and guidelines for the surgical fixation of LCF have not been established. The aim of this study was to compare patient-reported functional outcome after open reduction and internal fixation with the clavicle hook plate (CHP) and the superior clavicle plate with lateral extension (SCPLE). METHODS: A dual-center retrospective cohort study was performed. All patients operatively treated for unstable Neer type II and type V LCF between 2011 and 2016, with the CHP (n = 23) or SCPLE (n = 53), were eligible for inclusion. The primary outcome was the QuickDASH score. Secondary outcomes were the numerical rating scale (NRS) pain score, complications, and implant removal. RESULTS: A total of 67 patients (88%) were available for the final follow-up. There was a significant difference in bicortical lateral fragment size, 15 mm (± 4, range 6-21) in the CPH group compared to 20 mm (± 8, range 8-43) in the SCPLE group (p ≤ 0.001). There was no significant difference in median QuickDASH score (CHP; 0.00 [IQR 0.0-0.0], SCPLE; 0.00 [IQR 0.0-4.5]; p = 0.073) or other functional outcome scores (NRS at rest; p = 0.373, NRS during activity; p = 0.559). There was no significant difference in median QuickDASH score or other functional outcome scores between Neer type II and type V fractures. There was no significant difference in complication rate, CHP 11% and SCPLE 8% (relative risk 1.26; [95% CI 0.25-6.33; p = 0.777]). The implant removal rate was 100% in the CHP group compared to 42% in the SCPLE group (relative risk 2.40; [95% CI 1.72-3.35; p ≤ 0.001]). CONCLUSION: Both the CHP and SCPLE are effective fixation methods for the treatment of unstable LCF, resulting in excellent patient-reported functional outcome and similar complication rates. SCPLE fixation is an effective fixation method for the treatment of both Neer type II and type V LCF. The SCPLE has a lower implant removal rate. Therefore, if technically feasible, we recommend SCPLE fixation for the treatment of unstable LCF.

Effectiveness of prehospital trauma triage systems in selecting severely injured patients: Is comparative analysis possible?

INTRODUCTION: In an optimal trauma system, prehospital trauma triage ensures transport of the right patient to the right hospital. Incorrect triage results in undertriage and overtriage. The aim of this systematic review is to evaluate and compare prehospital trauma triage system quality worldwide and determine effectiveness in terms of undertriage and overtriage for trauma patients. METHODS: A systematic search of Pubmed/MEDLINE, Embase, and Cochrane Library databases was performed, using "trauma", "trauma center," or "trauma system", combined with "triage", "undertriage," or "overtriage", as search terms. All studies describing ground transport and actual destination hospital of patients with and without severe injuries, using prehospital triage, published before November 2017, were eligible for inclusion. To assess the quality of these studies, a critical appraisal tool was developed. RESULTS: A total of 33 articles were included. The percentage of undertriage ranged from 1% to 68%; overtriage from 5% to 99%. Older age and increased geographical distance were associated with undertriage. Mortality was lower for severely injured patients transferred to a higher-level trauma center. The majority of the included studies were of poor methodological quality. The studies of good quality showed poor performance of the triage protocol, but additional value of EMS provider judgment in the identification of severely injured patients. CONCLUSION: In most of the evaluated trauma systems, a substantial part of the severely injured patients is not transported to the appropriate level trauma center. Future research should come up with new innovative ways to improve the quality of prehospital triage in trauma patients.

Operative versus nonoperative treatment of proximal humeral fractures: a systematic review, meta-analysis, and comparison of observational studies and randomized controlled trials.

BACKGROUND: There is no consensus on the choice of treatment for displaced proximal humeral fractures in older patients (aged > 65 years). The aims of this systematic review and meta-analysis were (1) to compare operative with nonoperative management of displaced proximal humeral fractures and (2) to compare effect estimates obtained from randomized controlled trials (RCTs) and observational studies. METHODS: The databases of MEDLINE, Embase, CENTRAL (Cochrane Central Register of Controlled Trials), and CINAHL (Cumulative Index to Nursing and Allied Health Literature) were searched on September 5, 2017, for studies comparing operative versus nonoperative treatment of proximal humeral fractures; both RCTs and observational studies were included. The criteria of the Methodological Index for Non-Randomized Studies, a validated instrument for methodologic quality assessment, were used to assess study quality. The primary outcome measure was physical function as measured by the absolute Constant-Murley score after operative or nonoperative treatment. Secondary outcome measures were major reinterventions, nonunion, and avascular necrosis. RESULTS: We included 22 studies, comprising 7 RCTs and 15 observational studies, resulting in 1743 patients in total: 910 treated operatively and 833 nonoperatively. The average age was 68.3 years, and 75% of patients were women. There was no difference in functional outcome between operative and nonoperative treatment, with a mean difference of -0.87 (95% confidence interval, -5.13 to 3.38; P = .69; I2 = 69%). Major reinterventions occurred more often in the operative group. Pooled effects of RCTs were similar to pooled effects of observational studies for all outcome measures. CONCLUSIONS: We recommend nonoperative treatment for the average elderly patient (aged > 65 years) with a displaced proximal humeral fracture. Pooled effects of observational studies were similar to those of RCTs, and including observational studies led to more generalizable conclusions.

High Irritation and Removal Rates After Plate or Nail Fixation in Patients With Displaced Midshaft Clavicle Fractures.

BACKGROUND: Studies comparing plate with intramedullary nail fixation of displaced midshaft clavicle fractures show faster recovery in the plate group and implant-related complications in both groups after short-term followup (6 or 12 months). Knowledge of disability, complications, and removal rates beyond the first postoperative year will help surgeons in making a decision regarding optimal implant choice. However, comparative studies with followup beyond the first year or two are scarce. QUESTIONS/PURPOSES: We asked: (1) Does plate fixation or intramedullary nail fixation for displaced midshaft clavicle fractures result in less disability? (2) Which type of fixation, plate or intramedullary, is more frequently associated with implant-related irritation and implant removal? (3) Is plate or intramedullary fixation associated with postoperative complications beyond the first postoperative year? METHODS: Between January 2011 and August 2012, patients with displaced midshaft clavicle fractures were enrolled and randomized to plate or intramedullary nail fixation. A total of 58 patients with plate and 62 patients with intramedullary nails initially were enrolled. Minimum followup was 30 months (mean, 39 months; range, 30-51 months). Two patients (3%) with plate fixation and two patients (3%) with intramedullary nails were lost to followup. The QuickDASH was obtained at final followup and compared between patients who had plate fixation and those who had intramedullary nail fixation. Postoperative complications measured include infection, implant-related irritation, implant failure, nonunion, and refracture after implant removal. Indications for implant removal included implant-related irritation, implant failure, nonunion, patient's wish, or surgeon's preference. RESULTS: Between patients with plate versus intramedullary nail fixation, there were no differences in QuickDASH scores (plate, 1.8 ± 3.6; intramedullary nail, 1.8 ± 7.2; mean difference, -0.7; 95% CI, -2.2 to 2.04; p = 0.95). The proportion of patients having implant-related irritation was not different (39 of 56 [70%] versus 41 of 62 [66%]; relative risk, 1.05; 95% CI, 0.82-1.35; p = 0.683). Intramedullary fixation was associated with a higher likelihood of implant removal (51 of 62 [82%] versus 28 of 56 [50%]; relative risk, 1.65; 95% CI, 1.24-2.19; p < 0.001). Among the removed implants more plates than intramedullary nails were removed after the 1-year followup (12 of 28 [43%] versus six of 51 [12%]; p = 0.002). There were no infections, implant breakage, nonunions, or refractures between the 1-year and final followup in either group. CONCLUSIONS: After a mean followup of 39 months, disability scores were excellent. Major complications did not occur after the 1-year followup. A frequent and bothersome problem after both surgical treatments is implant-related irritation, resulting in high rates of implant removal, after 1 year. Future research could focus on analyzing risk factors for implant irritation or removal. LEVEL OF EVIDENCE: Level II, therapeutic study.

Anteroinferior versus superior plating of clavicular fractures.

BACKGROUND: Open reduction and plate fixation has gained recognition as an effective treatment for certain types of clavicular fractures. However, 88% of cases report some implant-related problems. To determine the optimal plate position, the aim of the present study was to compare implant-related irritation and proportion of plate removal in patients with clavicular fractures undergoing plate fixation by an anteroinferior or superior approach. METHODS: Retrospectively collected data of 39 patients who underwent anteroinferior plating for displaced midshaft clavicular fractures were compared with prospectively collected data of 60 patients who were treated with superior plate fixation as part of a multicenter randomized controlled trial. Electronic medical records were reviewed for reports of complications, in particular, implant-related irritation and implant removal during follow-up. In addition, all patients were contacted in June 2014 to obtain additional information. The primary outcome parameter was implant-related irritation. RESULTS: Univariate and multivariate regression analysis showed plate position was not significantly associated with implant-related irritation. Higher rates of asymptomatic patients with the plate still in place were observed in the anteroinferior group (46% vs 22%, P = .01). Almost an equal percentage of implant removals was seen in both groups because of implant irritation (36% vs 37%, P = .938). CONCLUSIONS: The present study found the surgical approach of clavicular plating was not associated with implant-related irritation. Future studies are needed to determine whether there is an optimal approach for clavicle plating.

Introducing the Surgical Therapeutic Index in trauma surgery: an assessment tool for the benefits and risks of operative fracture treatment strategies.

BACKGROUND: The Surgical Therapeutic Index (STI) has been described as an indicator of the benefits and risks of surgical treatment. The index is calculated by dividing the cure rate of an operative treatment by the complication rate. This study introduces the STI in trauma surgery by comparing the indices for surgical plate fixation (PF) and intramedullary fixation (IMF) of displaced midshaft clavicular fractures. METHODS: In a previously reported, randomized controlled fashion, 120 patients were assigned to PF or IMF. Cure was defined by a Disabilities of the Arm, Shoulder and Hand score of 8 or less. Complications were noted as present or not present for each follow-up assessment, and a panel of experts provided weights to the severity of complications. STIs were reported along with their 95% confidence intervals. The higher a procedure's STI, the higher the benefit/risk balance of that procedure. RESULTS: The nonweighted STI after 6 weeks was significantly higher in the PF group. During further follow- up, the differences leveled out and became nonsignificant. When weighting the STI for severity, the indices decrease but are significantly in favor of the PF group at 6 weeks and 6 months after surgery. At 1 year postoperatively, differences are not significant. CONCLUSION: The STI may be a reliable tool to assess the benefits and risks of operative fracture treatment. Further studies with consistent results of this new scoring system are needed before conclusions can be generalized. When determining the indices of PF and IMF, a significant difference in favor of PF was observed during the early phase of recovery.

Definitions of hospital-acquired pneumonia in trauma research: a systematic review.

PURPOSE: What are reported definitions of HAP in trauma patient research? METHODS: A systematic review was performed using the PubMed/MEDLINE database. We included all English, Dutch, and German original research papers in adult trauma patients reporting diagnostic criteria for hospital-acquired pneumonia diagnosis. The risk of bias was assessed using the MINORS criteria. RESULTS: Forty-six out of 5749 non-duplicate studies were included. Forty-seven unique criteria were reported and divided into five categories: clinical, laboratory, microbiological, radiologic, and miscellaneous. Eighteen studies used 33 unique guideline criteria; 28 studies used 36 unique non-guideline criteria. CONCLUSION: Clinical criteria for diagnosing HAP-both guideline and non-guideline-are widespread with no clear consensus, leading to restrictions in adequately comparing the available literature on HAP in trauma patients. Studies should at least report how a diagnosis was made, but preferably, they would use pre-defined guideline criteria for pneumonia diagnosis in a research setting. Ideally, one internationally accepted set of criteria is used to diagnose hospital-acquired pneumonia. LEVEL OF EVIDENCE: Level III.

Let's Agree to Disagree on Operative Versus Nonoperative Treatment for Distal Radius Fractures in Older People: Protocol for a Prospective International Multicenter Cohort Study.

BACKGROUND: Distal radius fractures are the most frequently encountered fractures in Western societies, typically affecting patients aged 50 years and older. Although this is a common injury, the best treatment for these fractures in older patients is still under debate. OBJECTIVE: This prospective study aims to compare the outcome of operatively and nonoperatively treated distal radius fractures in the older population. Only patients with distal radius fractures for which equipoise regarding the optimal treatment exists will be included. METHODS: This prospective international multicenter observational cohort study will be designed as a natural experiment. Natural experiments are observational studies in which treatment allocation is determined by factors outside the control of the investigators but also (largely) independent of patient characteristics. Patients aged 65 years and older with an acute distal radius fracture will be considered for inclusion. Treatment allocation (operative vs nonoperative) will be based on the local preferences of the treating hospital either in Switzerland or the Netherlands. Hence, the process governing treatment allocation resembles that of randomization. Patients will be identified after treatment has been initiated. Based on the radiographs and baseline information of the patient, an expert panel of 6 certified trauma surgeons from 2 regions will provide their treatment recommendation. Only patients for whom the experts disagree on treatment recommendations will ultimately be included in the study (ie, for whom there is a clinical equipoise). For these patients, both operative and nonoperative treatment of distal radius fractures are viable, and treatment choice is predominantly determined by personal or local preference. The primary outcome will be the Patient-Rated Wrist Evaluation score at 12 weeks. Secondary outcomes will include the Physical Activity Score for the Elderly, the EQ questionnaire, pain, the living situation, range of motion, complications, and radiological outcomes. By including outcomes such as living situation and the Physical Activity Score for the Elderly, which are not relevant for younger cohorts, valuable information to tailor treatment to the needs of the older population can be gained. According to the sample size collection, which was based on the minimal important clinical difference of the Patient-Rated Wrist Evaluation, 92 patients will have to be included, with at least 46 patients in each treatment group. RESULTS: Enrollment began in July 2023 and is expected to continue until summer 2024. The final follow-up will be 2 years after the last patient is included. CONCLUSIONS: Although many trials on this topic have previously been published, there remains an ongoing debate regarding the optimal treatment for distal radius fractures in older patients. This observational study, which will use a fairly new methodological study design, will provide further information on treatment outcomes for older patients with distal radius fractures for which to date equipoise exists regarding the optimal treatment.

Natural experiments for orthopaedic trauma research: An introduction.

Natural experiments are observational studies of medical treatments in which treatment allocation is determined by factors outside the control of the investigators, arguably resembling experimental randomisation. Natural experiments in the field of orthopaedic trauma research are scarce. However, they have great potential due to the process governing treatment allocation and the existence of opposing treatment strategies between hospitals or between regions as a result of local education, conviction, or cultural and socio-economic factors. Here, the possibilities and opportunities of natural experiments in the orthopaedic trauma field are discussed. Potential solutions are presented to improve the validity of natural experiments and how to assess the credibility of such studies. Above all, it is meant to spark a discussion about its role within the field of orthopaedic trauma research.

Natural Experiments as a Study Method in Spinal Trauma Surgery: A Systematic Review.

STUDY DESIGN: Systematic review. OBJECTIVES: To determine if the natural experiment design is a useful research methodology concept in spinal trauma care, and to determine if this methodology can be a viable alternative when randomized controlled trials are either infeasible or unethical. METHODS: A Medline, Embase and Cochrane database search was performed between 2004 and 2023 for studies comparing different treatment modalities of spinal trauma. All observational studies with a natural experiment design comparing different treatment modalities of spinal trauma were included. Data extraction and quality assessment with the MINORS criteria was performed. RESULTS: Four studies with a natural experiment design regarding patients with traumatic spinal fractures were included. All studies were retrospective, one study collected follow-up data prospectively. Three studies compared different operative treatment modalities, whereas one study compared different antibiotic treatment strategies. Two studies compared preferred treatment modalities between expertise centers, one study between departments (neuro- and orthopedic surgery) and one amongst surgeons. For the included retrospective studies, MINORS scores (maximum score 18) were high ranging from 12-17 and with a mean (SD) of 14.6 (1.63). CONCLUSIONS: Since 2004 only four studies using a natural experiment design have been conducted in spinal trauma. In the included studies, comparability of patient groups was high emphasizing the potential of natural experiments in spinal trauma research. Natural experiments design should be considered more frequently in future research in spinal trauma as they may help to address difficult clinical problems when RCT's are infeasible or unethical.

Computed tomographic bone mineral density is independently associated with adverse in-hospital outcomes in Dutch level-1 trauma patients.

BACKGROUND: Aging, inactivity, and malnutrition are risk factors for adverse in-hospital outcomes and can manifest in bone loss. Use of bone mineral density (BMD) as an objective marker might improve early identification of patients at risk for complications. AIM: To assess the association of computed tomography (CT) determined BMD values of the first lumbar vertebra with in-hospital complications and outcomes in trauma patients. METHODS: All consecutive hospitalized trauma patients (≥ 16 years) that underwent CT-imaging within 7 days of admission in 2017 were included. Patients with an active infection or antibiotic treatment upon admission, severe neurologic trauma, or an unassessable vertebra were excluded. BMD at the first lumbar vertebra was determined with CT by placing a circular region of interest in homogeneous trabecular bone to obtain mean Hounsfield Units (HU). Regression analyses were performed to assess the association of BMD with in-hospital complications and outcomes. RESULTS: In total, 410 patients were included (median age: 49 years [interquartile range 30-64], 68.3% men, mean BMD 159 ± 66 HU). A total of 94 complications, primarily infection-related, were registered in 74 patients. After adjustment for covariates, a decrease of BMD by one standard deviation was significantly associated with increased risk of complications (odds ratio [OR] 1.9, 95% confidence interval [CI] 1.1-3.1), pneumonia (OR 2.2, 95% CI 1.2-4.5), delirium (OR 4.5, 95% CI 1.7-13.5), and intensive care unit (ICU) admission (OR 1.8, 95% CI 1.1-2.9). CONCLUSION: Bone mineral density of the first lumbar vertebra is independently associated with in-hospital complications, pneumonia, delirium, and ICU admission. These findings could help identify patients at risk early.

Outcome of severely injured patients in a unique trauma system with 24/7 double trauma surgeon on-call service.

BACKGROUND: The presence of in-house attending trauma surgeons has improved efficiency of processes in the treatment of polytrauma patients. However, literature remains equivocal regarding the influence of the presence of in-house attendings on mortality. In our hospital there is a double trauma surgeon on-call system. In this system an in-house trauma surgeon is 24/7 backed up by a second trauma surgeon to assist with urgent surgery or multiple casualties. The aim of this study was to evaluate outcome in severely injured patients in this unique trauma system. METHODS: From 2014 to 2021, a prospective population-based cohort consisting of consecutive polytrauma patients aged ≥ 15 years requiring both urgent surgery (≤ 24h) and admission to Intensive Care Unit (ICU) was investigated. Demographics, treatment, outcome parameters and pre- and in-hospital transfer times were analyzed. RESULTS: Three hundred thirteen patients with a median age of 44 years (71% male), and median Injury Severity Score (ISS) of 33 were included. Mortality rate was 19% (68% due to traumatic brain injury). All patients stayed ≤ 32 min in ED before transport to either CT or OR. Fifty-one percent of patients who needed damage control surgery (DCS) had a more deranged physiology, needed more blood products, were more quickly in OR with shorter time in OR, than patients with early definitive care (EDC). There was no difference in mortality rate between DCS and EDC patients. Fifty-six percent of patients had surgery during off-hours. There was no difference in outcome between patients who had surgery during daytime and during off-hours. Death could possibly have been prevented in 1 exsanguinating patient (1.7%). CONCLUSION: In this cohort of severely injured patients in need of urgent surgery and ICU support it was demonstrated that surgical decision making was swift and accurate with low preventable death rates. 24/7 Physical presence of a dedicated trauma team has likely contributed to these good outcomes.

Nonoperative treatment of multiple rib fractures, the results to beat: International multicenter prospective cohort study among 845 patients.

BACKGROUND: Optimal treatment (i.e. nonoperative or operative) for patients with multiple rib fractures remains debated. Studies that compare treatments are rationalized by the alleged poor outcomes of nonoperative treatment. METHODS: The aim of this prospective international multicenter cohort study (between January 2018 and March 2021) with one-year follow-up, was to report contemporary outcomes of nonoperatively treated patients with multiple rib fractures. Including 845 patients with three or more rib fractures. Primary outcome was in-hospital mortality. Secondary outcomes included hospital length of stay (HLOS), (pulmonary) complications, and quality of life. RESULTS: Mean age was 57.7 ± 17.0 years, median Injury Severity Score was 17 (13-22) and the median number of rib fractures was 6 (4-8). In-hospital mortality rate was 1.5% (n = 13), 112 (13.3%) patients had pneumonia and four (0.5%) patients developed a symptomatic non-union. The median HLOS was 7 (4-13) days, and median intensive care unit length of stay was 2 (1-5) days. Mean EQ-5D-5L index value was 0.83 ± 0.18 one year after trauma. Polytrauma patients had a median HLOS of 10 (6-18) days, a pneumonia rate of 17.6% (n = 77) and mortality rate of 1.7% (n = 7). Elderly patients (≥65 years) had a median HLOS of 9 (5-15) days, a pneumonia rate of 19.7% (n = 57) and mortality rate of 4.1% (n = 12). CONCLUSIONS: Overall, nonoperative treatment of patients with multiple rib fractures shows low mortality and morbidity rate and good quality of life after one year. Future studies evaluating the benefit of operative stabilisation should use contemporary outcomes to establish the therapeutic margin of rib fixation. LEVEL OF EVIDENCE: Level III, Therapeutic/Care Management.
