This report is being filed after the review of the following journal article: kusen j.Q.Et al (2021), efficacy of two integrated geriatric care pathways for the treatment of hip fractures: a cross-cultural comparison, european journal of trauma and emergency surgery, vol.Xx (xx), pages 1-10 (switzerland/netherlands).This cross-national dual centre cohort study was made to compare between two trauma geriatric care models, one swiss (ch) and one dutch (nl), to assess whether these models would perform similarly despite the possible differences in local clinical practices.Between 2014 to 2015, a total of 752 patients (aged 70 and above) who were treated surgically in either netherlands (n=513; 143 male and 370 female; mean age of 85 years) or switzerland (ch) hospital (n=239; 60 male and 179 female; mean age of 86 years) were included in the study.Type of implants used includes plate osteosynthesis (unknown), hemiarthroplasty (unknown), intramedullary nail (unknown), sliding hip screw [including dynamic hip screw by depuy synthes, oberdorf switzerland and competitor device] and the use of cannulated screws by depuy synthes, oberdorf switzerland.The sliding hip screw was used in 22 patients in ch and 43 patients in ch, while the cannulated screws was used in nl only in 17 patients.In ch, routine follow-up took place 6 weeks, 3 months and 1 year post-operatively.In the nl, routine follow-up usually took place 6 weeks after surgery and, if no complications occurred, a consult by phone was performed at 3 months post-operatively.In selected cases, no follow-up took place due to comorbidities.The following complications were reported as follows: switzerland (ch): an unknown number of patients with synthes device had a complicated course (n=104).An unknown number of patients with synthes device had = 1 surgical interventions secondary to bleeding (n=1), fracture (n=4), deep surgical site infection (n=3), inadequate post-operative outcome/reduction in post-operative radiograph requiring revision surgery (n=8), and implant dislocation (n=5).An unknown number of patients with synthes device died at 30-days (n=27), 90-days (n=42), and at 1-year postoperatively (n=61).Netherland (nl): an unknown number of patients with synthes device had a complicated course (n=263).An unknown number of patients with synthes device had = 1 surgical interventions secondary to bleeding (n=1), fracture (n=10), deep surgical site infection (n=14), inadequate post-operative outcome/reduction in post-operative radiograph requiring revision surgery (n=3), and implant dislocation (n=4).An unknown number of patients with synthes device died at 30-days (n=43), 90-days (n=88), and at 1-year postoperatively (n=146).This report is for an unknown synthes dhs constructs.A copy of the literature article is being submitted with this medwatch.This report is for one (1) unk - constructs: dhs/dcs.This is report 2 of 2 for complaint (b)(4).
