Purpose: Elective implant removal (IR) in the upper extremity remains controversial. Implants in the olecranon and clavicle are commonly removed for prominence, unlike in the distal radius. Patient-reported symptomatic cannot be verified, and nonspecific discomfort remains unquantified. In this study, indications and outcomes of IR at the clavicle, olecranon and distal radius were evaluated, with a focus on postoperative patient satisfaction. Materials and methods: In this retrospective, single-center cohort study, patients, who received elective IR of the clavicle, olecranon and distal radius were included. Patients were followed up at least six weeks after IR. Outcomes included patient satisfaction, symptom resolution, and complications. Results: One hundred and eighty-nine patients were included. Unspecific symptoms of discomfort were the most prevalent indication for IR (48.7%), followed by pain (29.6%) and objective limited range of motion (ROM) (7%). Pain and limited ROM combined was observed in 13.8%. Subjective benefit following IR was described in 54%. Patients with limited ROM (OR 4.7, p < 0.001) or pain (OR 4.1, p < 0.001) were more likely to experience alleviation of complaints. Patients with unspecific symptoms of discomfort, often did not report improvement. Major complications occurred in 2%. Refractures were detected at the clavicle (3.7%) and at the olecranon (2.5%). Minor complication rate was 5%. Conclusion: IR is a safe procedure in the upper extremity. Indications based on unspecific symptoms of discomfort have a significant lower rate of patient satisfaction postoperatively. Elective IR should be considered cautiously, if it is driven primarily by unspecific symptoms of discomfort. Patient education is relevant to prevent dissatisfying outcome.

In a surgical career, teaching of surgical procedures plays a central role. In this study we want to evaluate the influence of teaching in appendectomies on the in-hospital outcome. Retrospectively, 26,436 cases from the national quality measurement database (AQC) between the years 2009 and 2017 were evaluated using the diagnosis and the procedure codes. Included were all cases with appendicitis (International Classification of Diseases diagnostic codes K35-K37), surgical treatment (appendectomy), and a documented teaching status of the procedure. Variables were sought in bivariate and multivariate analyses. The occurrence of any complication was the primary outcome, whereas in-hospital mortality was the secondary outcome. A total of 17,106 patients with a mean age of 37 ± 19 years remained for final analysis. A total of 6267 operations (37%), were conducted as teaching-operations. Seventy-four percent of all teaching procedures were performed by residents. We found no statistical association between teaching operations and complication rates or mortality. However, the teaching group showed longer duration of surgery (+ 11%). There was no influence of the training status of the appendectomy procedure on complication rates and in-hospital mortality. However, there was a prolonged duration of surgery. Despite these statistically significant differences, a comparable clinical outcome was observed in all patients, thus justifying the benefits of resident training.

Introduction: There has been growing evidence in trauma literature that differences in insurance status lead to inequality in treatment and outcome. Most studies comparing uninsured to insured patients were done in the USA. We sought to gain further insights into differences in the outcomes of trauma patients in a healthcare system with mandatory public health coverage by comparing publicly versus privately insured patients. Methods: We used a prospective national quality assessment database from the Arbeitsgemeinschaft für Qualitätssicherung in der Chirurgie (AQC). More than 80 surgical departments in Switzerland are part of this quality program. We included all patients in the AQC database with any S- or T-code diagnosis according to the International Classification of Diseases ICD-10 (any injuries) who were treated during the 11-year period of 2004–2014. Missing insurance status information was an exclusion criterion. In total, 30,175 patients were included for analysis. The primary outcome was in-hospital mortality. Secondary outcomes included overall and intra- and postoperative complications. Bi- and multivariate analyses were performed, adjusted for insurance status, age, sex, American Society of Anesthesiologists (ASA) physical status category, type of injury, and surgeon’s level of experience. Results: In total, 76.8% (n = 23,196) of the patients were publicly insured. Patients with public insurance were significantly younger (p < 0.001), more often male (p < 0.001), and in better general health according to the ASA physical status category (p < 0.001). Length of pre- and postoperative stay and the number of operations per case were similar in the two groups. Patients with public insurance had a lower mortality rate (1.3% vs. 1.9%, p < 0.001), but after adjusting for confounders, insurance status was not a predictor of mortality. Overall complication rates were significantly higher for publicly insured patients (8.4% vs. 6.2%, p < 0.001), and after adjusting for confounders, insurance status was identified as an independent risk factor for overall complications (p < 0.001). Conclusion: Differences exist with respect to patient and procedural characteristics: publicly insured patients were younger, more often male, and scored better on ASA physical status. Insurance status seems not to be a predictor for fatal outcome after trauma, although it is associated with complications.

Background: Thoracic injuries are a very common entity throughout all age groups. With rising numbers of geriatric patients, characteristics of this patient group need to be better defined. The aim of this study was to investigate the impact of age on the outcome of thoracic trauma. In this project we provide a stratification of differentiated age groups regarding outcome parameter on rib fractures. Methods: The study employed a retrospective design using data from patients who sustained thoracic trauma and received treatment at a level I trauma center over a 5-year period. Patients with the same pattern of injury and gender but different age (above and below 70 years) were matched. Results: The mean age of the study population was 57 ± 19 years, 69% were male, 54% of patients had preexisting comorbidities. Hemothorax was present in 109 (16%), pneumothorax in 204 (31%) and lung contusions in 136 patients (21%). The overall complication rate was 36%, with a mortality rate of 10%. The matched pair analysis of 70 pairs revealed a higher prevalence of comorbidities in the older age group. They had significantly fewer pulmonary contusions and pneumothoraces than the younger patients and a shorter length of stay. However, the older age group had a significantly higher mortality rate. Conclusions: Geriatric patients with rib fractures exhibit different patterns of intrathoracic injuries compared to their younger counterparts. Although numeric age may not be the most accurate predictor of adverse outcome, we found that higher age was associated with a clear trend towards an increased mortality rate. Our findings build a basis for further research to evaluate the outcome of age for instance with the tool of a rib fracture scoring system within stratified age groups in order to identify patients at major risk.

The coronavirus has caused a worldwide pandemic with serious impacts on our healthcare systems. Many countries experienced a decline in traumatological patient volume. The aim of this study is to evaluate the impact of the first lockdown on traumatological patient volume in Switzerland. We retrospectively used a prospective national quality measurement database. We compared the period of the first lockdown in Switzerland from March 17 to April 26, 2020 to the same period in the years 2018 and 2019. Included were all adult patients with any S-code (trauma) according to the International Classification of Diseases. In total, we assessed 3874 patients (1779 in the year 2018, 1303 in the year 2019, and 792 in the year 2020) with a mean age of 61 ± 21 years. The patients during the lockdown period had significantly more injuries to the hip and forearm, had more comorbidities, and were more likely to have statutory insurance. During the lockdown period, more thromboembolism prophylaxis or anticoagulation was applied, and more patients needed antibiotic treatment. The present study demonstrated a 40–55% reduction in patient volume during the lockdown period in Switzerland compared to the previous years. The in-hospital mortality and complication rate during the lockdown period remained stable. This study suggests that in-hospital care for trauma patients in Switzerland was not substantially affected by the first lockdown.

Methods: We examined a quality measurement database containing de-identified cases from across Switzerland. All patients with a complete dataset treated between 2015 and 2021 were included. A case-control matching method (same age, comorbidity, sex, diagnosis, admission type, and insurance coverage) was used to evaluate the impact of pre-admission residence. The outcomes measured included complications during hospitalization, in-hospital mortality, and length of stay. Statistical significance was set at a p-value of <0.001 due to our large size of analyzed cases. Results: We noted a higher prevalence of comorbidities and higher ASA scores among the 2130 (1.9 %) patients admitted from long-term care facilities (LTCFs). Complication rates in the LTCF group were higher than those in the home group (15 % vs. 6.9 %, p = <0.001). Pneumonia was the most frequent complication in both groups. The in-hospital mortality rate was also significantly higher in the LTCF group than the home group (5.8 % vs. 1.1 %, p = <0.001). However, matched-pair analysis showed no significant difference in complication rates and overall mortality between the two groups. Patients admitted from LTCFs even had a shorter hospital stay (7.5 ± 8.7 days vs. 8.9 ± 7.9 days, p = <0.004). Conclusions: Despite higher complication and mortality rates among LTCF patients, the matched-pair analysis showed no significant differences in these rates between the two groups. However, patients from LTCFs were discharged earlier, indicating the effectiveness of Switzerland's care system for older adults living in nursing homes.
