Abstract
Introduction
Most western countries have implemented fast-track hip fracture aiming at surgery within 24 hours, since the mortality rate hereafter rises markedly.
In Greenland, it is not achievable to operate within 24 hours. Arctic people live in sparsely populated areas and Greenland's population is scattered along the vast coastline. All patients must be chartered to Nuuk by airplane which can take up till several days to weeks, due to logistics and the Arctic weather. This presents a challenge regarding adhering to western guidelines. The operative delay may be acceptable though, as it is the impression that the Greenlandic population survives and endures better than patients of western populations.
However, as data are lacking, we aimed to describe mortality among hip fracture patients in Greenland taking frailty and comorbidities into account.
Method
All patients with ICD-10 codes DS720, DS721 and DS722 from 2018-2022 were identified as 261 patients diagnosed with hip fractures. Variables including time of diagnosis, time to operation, reasons for delay, ASA-score, Charlson Comorbidity index, time of death, and other possible confounding variables were analyzed. Primary outcome was mortality rates at 30-day post-OP and 1-year post-OP.
Results
The average time from fracture to operation was 91.4 hours. In the Danish Cohort (DC) 70,6 % of patient were operated within 24 hours. Overall, 30-day mortality was 9,9 %, and 1-year mortality was 29,4 %, compared to the DC with 10,8 % 30-day mortality and 28,3 % 1-year mortality.
Multivariate regression was conducted, showing no statiscal significant increase in mortality, despite extended delay.
Conclusion
With no increase in death, the authors find it justifiable that patients in Greenland endure longer delays than the western population. The influence on further adverse effects needs to be investigated as well as causes of survival, but perhaps the Arctic people unveil mechanisms for raised survival among other populations.
