Epidemiology of burn patients admitted in the Netherlands:: a nationwide registry study investigating incidence rates and hospital admission from 2014 to 2018
PURPOSE: The aim of this study was to gain insight into the epidemiology of burn patients admitted to a hospital without a burn center or referred to a burn center. METHODS: This retrospective, nationwide, cohort study included patients with burns or inhalation trauma, admitted between 2014 and 2018, from a national trauma registry. The primary outcome measure was admission to a hospital with or without a burn center. Secondary outcome measures were patient and injury characteristics, Intensive Care Unit (ICU) admission and length of stay, and hospital length of stay (HLOS). RESULTS: Of the 5524 included patients, 2787 (50.4%) were treated at a non-burn center, 1745 (31.6%) were subsequently transferred to a burn center, and 992 (18.0%) were primarily presented and treated at a burn center. The annual number of patients decreased from 1199 to 1055 (− 12.4%). At all admission locations, a clear incidence peak was observed in children ≤ 4 years and in patients of ≥ 80 years. The number of ICU admissions for the entire population increased from 201 to 233 (33.0%). The mean HLOS for the entire population was 8 (SD 14) days per patient. This number remained stable over the years in all groups. CONCLUSION: Half of all burn patients were admitted in a non-burn center and the other half in a burn center. The number and incidence rate of patients admitted with burns or inhalation trauma decreased over time. An increased incidence rate was found in children and elderly. The number of patients admitted to the ICU increased, whereas mean hospital length of stay remained stable.

Abstract Background After on-scene examination and /or treatment, emergency medical services (EMS) nurses must decide whether the patient requires further assessment or treatment, most frequently in a hospital. The primary objective of this study was to assess the reliability of the current EMS protocol by determining whether the decision not to transport the patient to a care provider was correct or not. Methods Adults receiving on-scene medical care by an EMS rapid responder or full team without transport to the hospital were included in this prospective observational study. The primary outcome measure was secondary consultation within 24 h after an on-scene EMS evaluation without transport for the same or a closely related complaint. The secondary outcome measures were patient satisfaction, type of secondarily consulted health care provider, provisional and definitive diagnosis, and correctness of the EMS members’ decision to provide on-scene medical care without transport. Results Of the 1095 participating patients, 271 (24.7%) patients requested secondary medical attention for the same complaint. This percentage was significantly larger in incidents attended by an ambulance team than by a rapid responder (N = 248 (26.5%) vs. N = 23 (14.4%); p < 0.05). In eleven (1.0%) cases an urgent medical diagnosis requiring admission was missed. A total of 873 (79.7%) patients were satisfied with the decision not to be transported. In 44 (4.0%) cases the EMS nurse’s decision was rated incorrect since the patient needed help contradictory to the EMS nurse’s recommendation. Conclusions The data show that EMS nurses can effectively examine patients, but a low threshold of referral for consultation should be considered because one in four patients requested secondary medical attention for the same complaint(s) again. However, due to a low response rate (11.3%) more research is needed to further determine the safety of the current EMS protocol. Trial registration Not applicable
Technical errors and complications in orthopaedic trauma surgery
Introduction Adverse events and associated morbidity and subsequent costs receive increasing attention in clinical practice and research. As opposed to complications, errors are not described or analysed in literature on fracture surgery. The aim of this study was to provide a description of errors and complications in relation to fracture surgery, as well as the circumstances in which they occur, for example urgency, type of surgeon, and type of fracture. Methods All errors and complications were recorded prospectively in our hospital’s complication registry, which forms an integral part of the electronic medical patient file. All recorded errors and complications in the complication registry linked to fracture surgery between 1 January, 2000 and 31 December, 2010 were analysed. Results During the study period 4310 osteosynthesis procedures were performed. In 78 (1.8 %) procedures an error in osteosynthesis was registered. The number of procedures in which an error occurred was significantly lower (OR = 0.53; p = 0.007) when an orthopaedic trauma surgeon was part of the operating team. Of all 3758 patients who were admitted to the surgical ward for osteosynthesis, 745 (19.8 %) had one or more postoperative complications registered. There was no significant difference in the number of postoperative complications after osteosynthesis procedures in which an orthopaedic trauma surgeon was present or absent (16.7 vs. 19.1 %; p = 0.088; OR 0.85). Discussion In the present study the true error rate after osteosynthesis may have been higher than the rate found. Errors that had no significant consequence may be especially susceptible to underreporting. Conclusion The present study suggests that an osteosynthesis procedure performed by or actively assisted by an orthopaedic trauma surgeon decreases the probability of an error in osteosynthesis. Apart from errors in osteosynthesis, the involvement of an orthopaedic trauma surgeon did not lead to a significant reduction in the number of postoperative complications.

Which surgical technique may yield the best results in large, infected, segmental non-unions of the tibial shaft?:A scoping review
Purpose: Infected nonunion of the tibia with a large segmental bone defect is a complex and challenging condition for the patient and surgeon. This scoping review was conducted to identify existing evidence and knowledge gaps regarding this clinical scenario. Secondly, the objective of this study was to search for a valid recommendation on the optimal treatment. Methods: A comprehensive search was conducted in the bibliographic databases: PubMed, Embase.com, and Web of Science Core Collection. Studies reporting on bone transport techniques, the Masquelet technique, and vascularized fibular grafts in bone defects greater than 5 cm were included. Bone healing results and functional results were compared according to duration of nonunion, infection recurrence, bone consolidation, complication rate, external fixation time, and time until full weight-bearing. Results: Of the 2753 articles retrieved, 37 studies could be included on bone transport techniques (n = 23), the Masquelet technique (n = 7), and vascularized fibular grafts (n = 7). Respective bone union percentages were 94.3%, 89.5%, and 96.5%. The percentages of infection recurrence respectively were 1.6%, 14.4% and 7.0%, followed by respectively 1.58, 0.78, and 0.73 complications per patient. Conclusion: Bone transport was found to be the most widely studied technique in the literature. Depending on the surgeon’s expertise, vascularized fibular grafts may be held as a favourable alternative. This review indicates that further high-quality research on large bone defects (≥ 5 cm) in patients with infected tibial nonunions is necessary to gain more insight into the potentially beneficial results of vascularized fibular grafts and the Masquelet technique.</p

The course of health status and (health-related) quality of life following fracture of the lower extremity:A 6-month follow-up study
Purpose The aim of this prospective study was to describe the course of health status (HS), health-related quality of life, and quality of life (QOL) in patients with lower extremity fractures (LEF) up to 6 months post-fracture. Methods Patients (n = 171; age range 18–100 years) completed the World Health Organization Quality of Life assessment instrument-Bref (WHOQOL-Bref) and the Short Musculoskeletal Function Assessment questionnaire (SMFA) at time of diagnosis (i.e., pre-injury status), 1 week, and 6 months post-fracture. Linear mixed modeling was performed. Results Interaction effects of time with treatment were detected for the WHOQOL-Bref facet Overall QOL and General health (p = .002) and Physical health (p = .003). Patients did not return to their pre-injury Physical health, Psychological health, and Environment 6 months post-fracture (p < .05). No effects were found for Social relationships. The SMFA subscale Lower extremity dysfunction showed main effects for time and treatment (p < .0001) with full recovery at 6 months (p = .998). An interaction effect of time with treatment was found for Daily life consequences (p < .0001) with nonoperatively treated patients showing full recovery (p = 1.00), whereas surgically treated patients did not (p = .002). Conclusions Six months after LEF, patients still experienced impaired physical and psychological health on the WHOQOL-Bref compared to their pre-injury status. However, patients showed full recovery on SMFA Lower extremity dysfunction, indicating that the choice of the questionnaire influences the derived conclusions. LEF did not affect satisfaction with social relationships.KeywordsHealth status, Health-related quality of life, Quality of life, Lower extremity fracture

Trauma mechanism and patient reported outcome in tibial plateau fractures with posterior involvement
Introduction: Posterior tibial plateau fractures (PTPF) have a high impact on functional outcome and the optimal treatment strategy is not well established. The goal of this study was to assess the relationship between trauma mechanism, fracture morphology and functional outcome in a large multicenter cohort and define possible strategies to improve the outcome. Methods: An international retrospective cohort study was conducted in five level-1 trauma centers. All consecutive operatively treated PTPF were evaluated. Preoperative imaging was reviewed to determine the trauma mechanism. Patient reported outcome was scored using the Knee injury and Osteoarthritis Outcome Score (KOOS). Results: A total of 145 tibial plateau fractures with posterior involvement were selected with a median follow-up of 32.2 months (IQR 24.1-43.2). Nine patients (6%) sustained an isolated posterior fracture. Seventy-two patients (49%) sustained a two-column fracture and three-column fractures were diagnosed in 64 (44%) patients. Varus trauma was associated with poorer outcome on the 'symptoms' (p = 0.004) and 'pain' subscales (p = 0.039). Delayed-staged surgery was associated with worse outcome scores for all subscales except 'pain'. In total, 27 patients (18%) were treated with posterior plate osteosynthesis without any significant difference in outcome. Conclusions: Fracture morphology, varus trauma mechanism and delayed-staged surgery (i.e. extensive soft-tissue injury) were identified as important prognostic factors on postoperative outcome in PTPF. In order to assess possible improvement of outcome, future studies with routine preoperative MRI to assess associated ligamentous injury in tibial plateau fractures (especially for varus trauma) are needed.

Identification of numerical chromosome aberrations in archival tumours by in situ hybridization to routine paraffin sections: Evaluation of 23 phaeochromocytomas
We have applied non-isotopic in situ hybridization (ISH) to interphase cell nuclei of 23 phaeochromocytomas (18 primary and 5 metastatic tumours) within routine paraffin-embedded tissue sections. Each tumour was screened for numerical aberrations with a defined alphoid repetitive DNA probe set containing DNA probes specific for chromosomes 1, 7, 15, and Y. Normal adrenal medullas and other normal human cell types served as cytogenetic controls. Preservation of tissue morphology enabled targeted analysis of tumour cells. The presence of numerical chromosome changes in the tumour cells could easily be evaluated by comparing the ISH results of the DNA probes. Numerical abnormalities not previously reported in this neoplasm included overrepresentation of chromosomes 1 and 7, loss of chromosome 15, and both gain and loss of chromosome Y (P values <0.01). The percentage of aneuploid cell nuclei in a tumour correlated well with the percentage of cells in the 4C peak of flow cytometric DNA histograms from these neoplasms. We conclude that interphase ISH can be used for the identification of new and reported cytogenetic changes in tumour cell nuclei within archival tissue sections. This novel procedure also allows for retrospective analysis of previously not karyotyped material
