Bicycle-related traumatic injuries: a retrospective study during COVID-19 pandemic.

Background: This study aimed to review bicycle-related injuries during the COVID-19 pandemic to assist with reinforcement or implementation of new policies for injury prevention.

Methods: This is a retrospective descriptive analysis of injuries sustained during cycling for patients 18 years old and above who presented to Singapore General Hospital from January to June 2021. Medical records were reviewed and consolidated. Descriptive analyses were used to summarize patient characteristics, and differences in characteristics subgrouped by triage acuity and discharge status were analyzed.

Results: The study included 272 patients with a mean age of 43 years and a male predominance (71.7%). Most presented without referrals (88.2%) and were not conveyed by ambulances (70.6%). Based on acuity category, there were 24 (8.8%) Priority 1 (P1) patients with 7 trauma activations, 174 (64.0%) and 74 (27.2%) P2 and P3 patients respectively. The most common injuries were fractures (34.2%), followed by superficial abrasion/contusion (29.4%) and laceration/wound (19.1%). Thirteen (4.8%) patients experienced head injury and 85 patients (31.3%) were documented to be wearing a helmet. The majority occurred on the roads as traffic accidents (32.7%). Forty-two patients (15.4%) were admitted with a mean length of stay of 4.1 d and 17 (6.3%) undergone surgical procedures. Out of 214 (78.7%) discharged patients, no re-attendances or mortality were observed. In the subgroup analysis, higher acuity patients were generally older, with higher proportions of head injuries leading to admission.

Conclusion: Our study highlights significant morbidities in bicycle-related injuries. There is also a high proportion of fractures in the young healthy male population. Injury prevention is paramount and we propose emphasizing helmet use and road user safety.
