ABSTRACT
Background: Management of hand trauma has evolved to incorporate assessment, treatment and rehabilitation of patients in a 'one-stop' clinic on initial presentation. Our aim was to evaluate the effect of coronavirus disease 2019 (COVID-19) on the choice of treatment for hand fractures using inter-rater agreement between surgeons. Methods: All patients with hand fractures during the COVID-19 lockdown from March to May 2020 were included in the study. Two experienced hand surgeons blinded to management and outcomes independently reviewed radiographic images and relevant clinical history to provide their opinion on optimal treatment. Weighted kappa analysis was performed to determine concordance and inter-rater agreement between the two surgeons and actual management. Results: The study included 82 patients (62 men and 20 women) with a mean age of 40.3 (SD 19.7). The injuries occurred most often at home following an accident (34%) or a fall (28%). Fractures involved the metacarpals in 29 patients and the distal phalanx in 22 patients. Thirty-five patients underwent surgery, whereas 47 were managed conservatively. Overall agreement between actual management and consultant A and consultant B was moderate (κ = 0.55, p < 0.0001 and κ = 0.63, p < 0.0001, respectively). Subgroup analysis showed a weak agreement between actual management of metacarpal fractures and consultant A and consultant B (κ = 0.22, p = 0.29 and κ = 0.47, p = 0.02, respectively). Inter-rater agreement was substantial for management of metacarpal fractures (κ = 0.73, p < 0.0001), but weak for distal phalanx fractures (κ = 0.29, p = 0.03). Conclusion: Our study has shown that overall management of hand fractures remained optimised throughout the pandemic. However, a lack of concordance was observed in the management of metacarpals. Level of Evidence: Level IV (Therapeutic).
