‘Out of hours’ orthopaedics in an Irish regional trauma unit and the impact of COVID-19

Introduction MRHT is the regional trauma service for the Midlands, providing 24/7 orthopaedic cover. ‘Out of hours’ surgery is reserved for those occasions where waiting for the next operating list during normal working hours would result in an unacceptable outcome for the patient. Aims To identify how many ‘out-of-hours’ surgeries were performed and what proportion of the total workload was made up by these cases. Secondly, to identify the impact of COVID-19 on our workload as an acute trauma service. Methods We performed a retrospective analysis of all operations performed in the emergency orthopaedic theatre between January 2017 and October 2020. Included were all emergency orthopaedic procedures performed after 6 p.m. and before 8 a.m. We compared this to the total number of trauma surgeries performed in the same time period to calculate the percentage of our total operations. Results There were a total of 7615 orthopaedic trauma operations performed in the 193 weeks. 164 of these were ‘out-of-hours’. This represents 2.2% of the total operations performed and is equal to 0.84 cases per week. 55 of the 164 (33.5%) were performed in children under the age of 18. 62 were performed between 6 and 8 p.m., 61 between 8 and 10 p. m., 31 between 10 p.m. and midnight, and the remaining 10 were performed between midnight and 3 a.m. Conclusion Surgery out of hours has been associated with increased complications, and so decisions to perform emergency surgery should not be made lightly. However, sometimes they are unfortunately necessary and are some of the most important operations we can perform as orthopaedic surgeons.
