Background The management of hip fracture patients has been challenging across the UK in the wake of emergency coronavirus disease 2019 guidelines. Aims This retrospective, observational cohort study analyses the impact of the first lockdown during the early part of the coronavirus disease 2019 pandemic on the management of hip fracture patients at a district general hospital in the UK. Methods Comparative analysis to assess hip fracture patients treated at this Trust between 1 April to 31 May 2019 and 1 April to 31 May 2020 was undertaken. The primary outcome measures appraised were 30 and 60-day mortality and the secondary outcome measure included time to surgery. Results There was a higher 30 and 60-day mortality rate in the first lockdown period at 8.1% and 13.5%, respectively, compared to 1.96% and 5.88% in 2019. A significantly lower proportion of hip fracture patients at 59.46% were operated within the 36h target time frame during the first lockdown. Conclusion In our Trust, hip fractures were treated as obligatory injuries. However, the mortality was higher in the 2020 cohort with a significant reduction in patients achieving the recommended ‘36 hours’ time to surgery target and accruement of Best Practice Tariff. Enhanced infection control strategies have prepared us for the future.

In this paper, transient stability analysis of a detailed model multi-machine power system was carried out to focus on the impact of HVDC link on system stability by comparing the critical fault clearing times of two operational scenarios, namely an AC transmission system with and without parallel HVDC transmission. The advantage and performance of AC-DC transmission for the improvement of response to transient instability caused by phase to ground fault was researched by detail simulation carried out in MATLAB/SIMULINK.
