Concepts, utilization, and perspectives on the Dutch Nationwide Trauma registry: a position paper.

Over the last decades, the Dutch trauma care have seen major improvements. To assess the performance of the Dutch trauma system, in 2007, the Dutch Nationwide Trauma Registry (DNTR) was established, which developed into rich source of information for quality assessment, quality improvement of the trauma system, and for research purposes. The DNTR is one of the most comprehensive trauma registries in the world as it includes 100% of all trauma patients admitted to the hospital through the emergency department. This inclusive trauma registry has shown its benefit over less inclusive systems; however, it comes with a high workload for high-quality data collection and thus more expenses. The comprehensive prospectively collected data in the DNTR allows multiple types of studies to be performed. Recent changes in legislation allow the DNTR to include the citizen service numbers, which enables new possibilities and eases patient follow-up. However, in order to maximally exploit the possibilities of the DNTR, further development is required, for example, regarding data quality improvement and routine incorporation of health-related quality of life questionnaires. This would improve the quality assessment and scientific output from the DNTR. Finally, the DNTR and all other (European) trauma registries should strive to ensure that the trauma registries are eligible for comparisons between countries and healthcare systems, with the goal to improve trauma patient care worldwide.

Funnel plots a graphical instrument for the evaluation of population performance and quality of trauma care: a blueprint of implementation.

BACKGROUND: Using patient outcomes to monitor medical centre performance has become an essential part of modern health care. However, classic league tables generally inflict stigmatization on centres rated as "poor performers", which has a negative effect on public trust and professional morale. In the present study, we aim to illustrate that funnel plots, including trends over time, can be used as a method to control the quality of data and to monitor and assure the quality of trauma care. Moreover, we aimed to present a set of regulations on how to interpret and act on underperformance or overperformance trends presented in funnel plots. METHODS: A retrospective observational cohort study was performed using the Dutch National Trauma Registry (DNTR). Two separate datasets were created to assess the effects of healthy and multiple imputations to cope with missing values. Funnel plots displaying the performance of all trauma-receiving hospitals in 2020 were generated, and in-hospital mortality was used as the main indicator of centre performance. Indirect standardization was used to correct for differences in the types of cases. Comet plots were generated displaying the performance trends of two level-I trauma centres since 2017 and 2018. RESULTS: Funnel plots based on data using healthy imputation for missing values can highlight centres lacking good data quality. A comet plot illustrates the performance trend over multiple years, which is more indicative of a centre's performance compared to a single measurement. Trends analysis offers the opportunity to closely monitor an individual centres' performance and direct evaluation of initiated improvement strategies. CONCLUSION: This study describes the use of funnel and comet plots as a method to monitor and assure high-quality data and to evaluate trauma centre performance over multiple years. Moreover, this is the first study to provide a regulatory blueprint on how to interpret and act on the under- or overperformance of trauma centres. Further evaluations are needed to assess its functionality. LEVEL OF EVIDENCE: Retrospective study, level III.

Treatment of displaced intra-articular calcaneal fractures: A single-center experience study with 20 years follow-up.

INTRODUCTION: This study was conducted to identify the patient characteristics, classification, treatment, complications, and functional outcomes of operatively treated displaced intra-articular calcaneal fractures (DIACFs) in a level-I trauma center over a 20-year period. METHODS: Patients with a DIACF classified as Sanders ≥2 and operatively treated with percutaneous reduction and screw fixation (PSF) or open reduction and internal fixation (ORIF) between 1998 and 2017 were identified. Pre- and postoperative radiological assessments were performed. Functional outcomes were evaluated using the American Orthopaedic Foot & Ankle Society (AOFAS) score and the Maryland Foot Score (MFS). General health and patient satisfaction were assessed using the Short Form-36 Health Survey (SF-36) and the visual analog scale (VAS). RESULTS: In total, 120 patients with a DIACF that were operatively treated with PSF or ORIF. Of these patients, 72 with a total of 80 DIACFs completed the questionnaires (60%). The average follow-up was 130 months. Mean scores for PSF and ORIF were 74 and 75 for AOFAS, 78 and 78 for MFS, 68 and 61 for SF-36, and 7.7 and 7.5 for VAS, respectively. An infection was the most common complication associated with ORIF (31%), and hardware removal (58%) was the most common complication in patients treated with PSF. Overall, 36 patients (68%) were able to return to work after a median time 6 months (IQR, 3-7) and 6 months (IQR, 3,25-6,75) for PSF and ORIF treated, respectively CONCLUSION: This long-term follow-up study reviews ORIF using ELA and PSF in the treatment of DIACFs. This study shows that both treatments are capable of restoring the Böhler angle and yield relatively good long-term functional outcomes. Differences in complication rates were apparent, infectious problems are inherent to ORIF using ELA, and hardware removal is associated with PSF.

The Dutch nationwide trauma registry: The value of capturing all acute trauma admissions.

INTRODUCTION: Twenty years ago the Dutch trauma care system was reformed by the designating 11 level one Regional trauma centres (RTCs) to organise trauma care. The RTCs set up the Dutch National Trauma Registry (DNTR) to evaluate epidemiology, patient distribution, resource use and quality of care. In this study we describe the DNTR, the incidence and main characteristics of Dutch acutely admitted trauma patients, and evaluate the value of including all acute trauma admissions compared to more stringent criteria applied by the national trauma registries of the United Kingdom and Germany. METHODS: The DNTR includes all injured patients treated at the ED within 48 hours after trauma and consecutively followed by direct admission, transfers to another hospital or death at the ED. DNTR data on admission years 2007-2018 were extracted to describe the maturation of the registry. Data from 2018 was used to describe the incidence rate and patient characteristics. Inclusion criteria of the Trauma Audit and Research (TARN) and the Deutsche Gesellschaft für Unfallchirurgie (DGU) were applied on 2018 DNTR data. RESULTS: Since its start in 2007 a total of 865,460 trauma cases have been registered in the DNTR. Hospital participation increased from 64% to 98%. In 2018, a total of 77,529 patients were included, the median age was 64 years, 50% males. Severely injured patients with an ISS≥16, accounted for 6% of all admissions, of which 70% was treated at designated RTCs. Patients with an ISS≤ 15were treated at non-RTCs in 80% of cases. Application of DGU or TARN inclusion criteria, resulted in inclusion of respectively 5% and 32% of the DNTR patients. Particularly children, elderly and patients admitted at non-RTCs are left out. Moreover, 50% of ISS≥16 and 68% of the fatal cases did not meet DGU inclusion criteria CONCLUSION: The DNTR has evolved into a comprehensive well-structured nationwide population-based trauma register. With 80,000 inclusions annually, the DNTR has become one of the largest trauma databases in Europe The registries strength lies in the broad inclusion criteria which enables studies on the burden of injury and the quality and efficiency of the entire trauma care system, encompassing all trauma-receiving hospitals.

Complications of implant removal after healed hip fractures.

INTRODUCTION: Osteosynthesis of pertrochanteric fractures is one of the most frequently performed procedures in orthopaedic trauma care. Auto-dynamization during fracture healing can lead to lateralization of the screw or blade. This can cause debilitating complaints, which sometimes necessitate the removal of the screw or blade. After removal of the implant, we observed spontaneous femoral neck fractures in five patients. This article presents an evaluation of these cases with reference to literature. MATERIALS AND METHODS: Five cases of spontaneous femoral neck fracture (SFNF) after cephalomedullary nail removal are described. A literature search was performed on the incidence of chronic pain and gait impairment associated with auto-dynamization, and on risk factors for dynamization and complications after implant removal. Based on these findings recommendations are made for the prevention of SFNF. RESULTS: Over a 2-year period, we observed five cases of SFNF after cephalomedullary nail removal. In literature, reduced mobility, gait impairment and chronic pain are associated with screw or blade dynamization. Pertrochanteric fractures with AO-type 2 classification were associated with more dynamization and screw lateralization and henceforth more trochanteric pain and gait disturbances. SFNF after cephalomedullary nail removal occurs with an incidence of at least 15%, affecting mostly elderly patients. This severe complication mostly occurs within 3 weeks after implant removal. Risk factors associated with SFNF are pre-existing systemic osteoporosis, stress-shielding, pre-loading of the implant and nail removal of the cephalomedullary implant. CONCLUSION: The clinical indications for implant removal in healed pertrochanteric fractures are not well established and should be restricted to specific cases. After removal of these implants without replacement partial weight-bearing should be advised strictly. Based on our findings it is recommended to replace the cephalomedullary nail with a shorter one, ideally combined with implant augmentation.
