Aim
Emergency physicians (EPs) often treat anterior shoulder dislocation, but epidemiology of anterior shoulder dislocation in the emergency department of Japan remains unclear. In this study, we clarified the success rate of anterior shoulder reduction performed by EPs.
Methods
This single‐center cohort study included patients with anterior shoulder dislocation for whom the EP performed initial reduction. The period was from January 2006 to March 2021 and we used the electronic medical record data of the tertiary care hospital. Our primary outcome was the success rate of the shoulder reduction performed by EP. The secondary outcome was to compare the success of reduction with the failure of the reduction.
Results
In total, 293 eligible patients were identified. Of these patients, 244 were included in this study. The success rate of the shoulder reduction performed by EP was 92.2% (225/244). EPs failed in successfully performing reduction in 19 (7.8%) cases of anterior shoulder dislocations. The failure group was older (
P
= 0.017), had a higher frequency of fall down in the mechanism of dislocation (
P
= 0.019), used intravenous analgesics more frequently (
P
= 0.004), used peripheral nerve blocks more frequently (
P
= 0.006), and had fewer patients who did not use drugs (
P
= 0.002). We could not perform statical adjustment because the sample size was small.
Conclusion
The success rate of the shoulder reduction performed by EPs was 92.2%. Older age might be associated with failure of shoulder reduction.
