Abstract Background: The aging population has a tremendous impact on health care. Geriatric trauma is expected to increase due to the lifestyle and activity of the aging population and will be one of the major future challenges in health care. Therefore, the aim of this study was to investigate differences between polytraumatized geriatric and non-geriatric patients regarding 1) mortality, 2) length of stay, and 3) complications with a matched pair analysis. Methods: We included patients older than 17 years with an Injury Severity Score (ISS) of 16 or more admitted to our level 1 trauma center between January 2008 and December 2015. The cohort was stratified into two groups (age < 70 years “non-geriatric”, age ≥ 70 years “geriatric”). One-to-one matching was performed based on gender, ISS, mechanism of injury (penetrating/blunt), Glasgow Coma Scale (GCS), base excess, and the presence of coagulopathy (INR ≥ 1.4). Outcome was compared using the paired t-test and McNemar-test. Results: A total of 1457 patients with a mean age of 62 (± 21) years were identified. There were 1022 male (72%) and 435 female patients. Three hundred forty six patients (24%) were older than 70 years. Matching resulted in 57 pairs. 1) Mortality (25% vs 32% respectively; p = 0.219) as well as 2) length of stay (12.5 (± 13.3) days vs 11.8 (± 11.8) days respectively, p = 0.754) were comparable between geriatric and non-geriatric polytraumatized patients. 3) The complication rate (34% vs. 56%, p = 0.031) was significantly higher in geriatric patients. Conclusion: Despite significantly higher complication rates amongst the geriatric trauma patients, there were no significant differences regarding mortality and length of stay in this matched pair analysis – indicating the possibility of similar outcome in geriatric polytraumatized patients receiving optimal care.

Geriatric trauma is expected to increase due to the lifestyle and activity of the aging population and will be among the major future challenges in health care. Therefore, the aim of this study was to investigate differences between polytraumatized geriatric and non-geriatric patients regarding mortality, length-of-stay and complications with a matched pair analysis. We included patients older than 17 years with an Injury Severity Score (ISS) of 16 or more admitted to our level 1 trauma center between January 2008 and December 2015. The cohort was stratified into two groups (age < 70 and ≥ 70 years). One-to-one matching was performed based on gender, ISS, mechanism of injury (penetrating/blunt), Glasgow coma scale (GCS), base excess, and the presence of coagulopathy (international normalized ratio (INR) ≥ 1.4). Outcome was compared using the paired t-test and McNemar-test. A total of 1457 patients were identified. There were 1022 male (70%) and 435 female patients. Three hundred and sixty-four patients (24%) were older than 70 years. Matching resulted in 57 pairs. Mortality as well as length-of-stay were comparable between geriatric and non-geriatric polytraumatized patients. Complication rate (34% vs. 56%, p = 0.031) was significantly higher in geriatric patients. This indicates the possibility of similar outcomes in geriatric polytraumatized patients receiving optimal care.

Abstract Objective Many microsurgeons fear high complication rates and free flap loss when vein grafting is necessary to restore blood flow at the recipient site. The aims of this study were to comparatively analyze surgical outcomes of interposition vein grafts (VG) in microsurgical primary lower extremity reconstruction and secondary salvage procedures. Patients and Methods A retrospective study was conducted on 58 patients undergoing free flap transfers with vein grafting for primary lower extremity reconstruction (cohort 1) and secondary salvage procedures (cohort 2) between 2002 and 2016. A matched-pair analysis of both cohorts and 58 non-VG flaps was performed. Patient data, preoperative conditions, flap and vein graft characteristics, postoperative outcomes such as flap failure, thrombosis, and wound complications were analyzed. Results A total of 726 free flap transfers were performed. In total, 36 primary reconstructions (5%) utilized 41 interposition VG (cohort 1). Postoperative vascular compromise was observed in 65 free flaps (9%). In total, 22 out of 65 secondary salvage procedures (33.8%) utilized 26 interposition VG (cohort 2). Two total flap losses occurred in each cohort (5.6 vs. 9.1%; p = 0.63). Postoperative complications were observed in 38.9% of free flaps in cohort 1 and 72.7% in cohort 2 (p = 0.01). Takeback for microvascular compromise was comparable in both cohorts (19.4 vs. 22.7%; p = 0.75). Microvascular complications occurred more often in cohort 2 (22.7%) than in cohort 1 (8.3%; p = 0.28). Lower extremity salvage rates were high among both cohorts (94.4 vs. 90.9%; p = 0.63). Matched-pair analysis did not show any relevant differences on takebacks and flap loss (p = 0.32 and p = 1.0). Conclusion In complex lower extremity reconstructions, VG can be performed with acceptable complication rates and outcomes in primary and especially in salvage cases. With careful planning and a consistent surgical protocol, VG can provide reliable success rates in limb salvage.

Abstract Background With a reported rate of 0.7–20%, postoperative spinal implant infection (PSII) is one of the most common complications after spine surgery. While in arthroplasty both haematoma formation and perioperative blood loss have been identified as risk factors for developing periprosthetic joint infections and preoperative anaemia has been associated with increased complication rates, literature on the aetiology of PSII remains limited. Methods We performed a matched-pair analysis of perioperative haemoglobin (Hb) and haematocrit (Hct) levels in aseptic and septic spine revision surgeries. 317 patients were included, 94 of which were classified as septic according to previously defined criteria. Patients were matched according to age, body mass index, diabetes, American Society of Anesthesiologists score and smoking habits. Descriptive summaries for septic and aseptic groups were analysed using Pearson chi-squared for categorical or Student t test for continuous variables. Results Fifty patients were matched and did not differ significantly in their reason for revision, mean length of hospital stay, blood transfusion, operating time, or number of levels operated on. While there was no significant difference in preoperative Hb or Hct levels, the mean difference between pre- and postoperative Hb was higher in the septic group (3.45 ± 1.25 vs. 2.82 ± 1.48 g/dL, p = 0.034). Conclusions We therefore show that the intraoperative Hb-trend is a predictor for the development of PSII independent of the amount of blood transfusions, operation time, number of spinal levels operated on and hospital length of stay, which is why strategies to reduce intraoperative blood loss in spine surgery need to be further studied.

AbstractReviewing and rating are important features of many social media websites, but they are found on many e-commerce sites too. The combination of social interaction and e-commerce is sometimes referred to as social commerce to indicate that people are supporting each other in the process of buying goods and services. Rgeviews of other consumers have a significant effect on consumer choice because they are usually considered authentic and more trustworthy than information presented by a vendor. The collaborative effort of consumers helps to make the right purchase decision (or prevent from a wrong one). The effect of reviews has often been researched in terms of helpfulness as indicated by their readers. Images are an important factor of helpfulness in reviews of experience goods where personal tastes and use play an important role. We extend this research to search goods where objective characteristics seem to prevail. In addition, we analyze potential interaction with other variables. The empirical study is performed with regression analyses on 3,483 search good reviews from Amazon.com followed by a matched pair analysis of 186 review pairs. We find that images have a significant positive effect on helpfulness of reviews of search goods too. This is especially true in case of short and ambiguous reviews.
