Abstract
Purpose: This research was designed to explore the incidence of anaemia before surgery and the rate of mortality one year after surgery for femoral neck fractures in older adults. It also investigated whether anaemia prior to surgery influences the likelihood of mortality within one year after the procedure.
Methods: A retrospective cohort analysis was undertaken at Honghui Hospital, a tertiary academic medical institution affiliated with Xi'an Jiaotong University in China. This investigation included elderly individuals who underwent surgery for femoral neck fractures within the year spanning from January to December 2021. The research team gathered data encompassing demographic details, levels of haemoglobin prior to surgery, existing comorbid conditions, and mortality statistics after one year.
Results: In this retrospective study, 994 patients were analyzed, with 84 reported fatalities. The incidence of anaemia in this group was 71.1%, affecting 707 individuals. Of these, 486 (48.8%) had mild anaemia, and 221 (22.2%) exhibited moderate to severe anaemia. Independent factors correlating with heightened one-year mortality risk included operative blood transfusions (odds ratio [OR] = 1.8, p = 0.0327), coronary artery disease presence (OR = 1.85, p = 0.0077), and moderate to severe anaemia (OR = 3.18, p = 0.0006). In contrast, higher body mass index (OR = 0.8, p < 0.0001) and red blood cell count (OR = 0.6, p = 0.0253) were linked to reduced one-year mortality risk. Multivariate logistic regression analyses underscored the independent association of moderate to severe anaemia with increased one-year mortality risk, with varying ORs across models: non-adjusted OR at 3.18 (p = 0.0006), Adjust I model OR at 3.08 (p = 0.0191), and Adjust II model OR at 2.96 (p = 0.0278).
Conclusion: At Honghui Hospital, affiliated with Xi'an Jiaotong University in China, anemia has been identified as a common condition among elderly patients undergoing surgery for femoral neck fractures, and it significantly contributes to an elevated risk of mortality within one year post-surgery. It is advisable to implement interventions aimed at managing anaemia before surgery, which should include setting haemoglobin thresholds that are not specific to any gender for its diagnosis.
期刊介绍：
International Orthopaedics, the Official Journal of the Société Internationale de Chirurgie Orthopédique et de Traumatologie (SICOT) , publishes original papers from all over the world. The articles deal with clinical orthopaedic surgery or basic research directly connected with orthopaedic surgery. International Orthopaedics will also link all the members of SICOT by means of an insert that will be concerned with SICOT matters.
Finally, it is expected that news and information regarding all aspects of orthopaedic surgery, including meetings, panels, instructional courses, etc. will be brought to the attention of the readers.
Manuscripts submitted for publication must contain a statement to the effect that all human studies have been approved by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
Reports of animal experiments must state that the "Principles of laboratory animal care" (NIH publication No. 85-23, revised 1985) were followed, as well as specific national laws (e.g. the current version of the German Law on the Protection of Animals) where applicable.
The editors reserve the right to reject manuscripts that do not comply with the above-mentioned requirements. The author will be held responsible for false statements or for failure to fulfil the above-mentioned requirements.
