Show moreBackground and Purpose: Two medical specialties, general surgery and orthopaedic surgery, with different training programs but matching trauma certification requirements, provide hip fracture surgery in the Netherlands. This study analyses treatment preferences and guideline adherence of Dutch surgeons with different surgical backgrounds.Patients and Methods: All hip fracture patients registered in the Dutch Hip Fracture Audit in 2018 and 2019 were included in this retrospective study. Four types of surgeons were distinguished: trauma-certified general surgeons (ST+), non-trauma certified general surgeons (ST-), trauma-certified orthopaedic surgeons (OT+) and non-trauma certified orthopaedic surgeons (OT-). Differences in patient characteristics, and practice variation in treatment choices and guideline adherence per fracture type were analysed using descriptive statistics.Results: 28,656 patients were included; 16,367 (57.1%) treated by ST +, 1,371 (4.8%) by ST-, 4,692 (16.4%) by OT+ and 6,226 (21.7%) by OT-. Few clinically relevant differences in patient characteristics and hospital processes were found between all surgeon groups. Displaced FNF were the most commonly treated fracture type for all types of surgeons. Both OT+ and OT- operated mostly (displaced) FNFs, while the fracture types treated by ST+ and ST- were more heterogeneous. For all fracture types, the orthopaedic surgeons performed THA and HA more often than general surgeons, while general surgeons more often placed SHS and IMN for specific fracture types. Guideline adherence was on average 68.4% and differed significantly per surgeon type (68.7% by ST+, 65.2% by ST-, 74.4% by OT+ and 63.6% by OT-(p<0.01)), as well as per fracture type: >90% treatment according to the guideline for trochanteric AO-31A2 and A3 fractures, 18.8% for AO-31A1 fractures and 51.7% guideline adherence for undisplaced FNF. Guideline adherence for displaced FNF varied depending on patient characteristics.Discussion: In the Netherlands, different surgical specialists treat different types of hip fractures and have different preferences concerning implants for hip fracture surgery in comparable patients. Guideline adherence of trauma- and non-trauma certified orthopaedics and general surgeons differs significantly. Reduction of practice variation should be strived for in order to improve hip fracture care. (C) 2021 The Authors. Published by Elsevier Ltd. Show less
