Management of a large outbreak of COVID-19 at a British Army training centre: lessons for the future.

INTRODUCTION: The COVID-19 pandemic has posed major challenges for infection control within training centres, both civilian and military. Here we present a narrative review of an outbreak that occurred at the Royal Military Academy Sandhurst (RMAS) in January-March 2021, in the context of the circulating, highly transmissible SARS-CoV-2 variant B.1.1.7. METHODS: Testing for SARS-CoV-2 was performed using a combination of reverse transcriptase PCR and Lateral Flow Devices (LFDs). Testing and isolation procedures were conducted in line with a pre-established symptom stratification system. Genomic sequencing was performed on 10 sample isolates. RESULTS: By the end of the outbreak, 185 cases (153 Officer Cadets, 32 permanent staff) had contracted confirmed COVID-19. This represented 15% of the total RMAS population. This resulted in 0 deaths and 0 hospitalisations, but due to necessary isolation procedures did represent an estimated 12 959 person-days of lost training. 9 of 10 (90%) of sequenced isolates had a reportable lineage. All of those reported were found to be the Alpha lineage B.1.1.7. CONCLUSIONS: We discuss the key lessons learnt from the after-action review by the Incident Management Team. These include the importance of multidisciplinary working, the utility of sync matrices to monitor outbreaks in real time, issues around Officer Cadets reporting symptoms, timing of high-risk training activities, infrastructure and use of LFDs. COVID-19 represents a vital learning opportunity to minimise the impact of potential future pandemics, which may produce considerably higher morbidity and mortality in military populations.

The Roper-Tuke total elbow arthroplasty. 4- to 10-year results of an unconstrained prosthesis.

We report the results of a series of 59 unconstrained total arthroplasties of the elbow after a mean follow-up of 6.5 years (4 to 10). All the patients had rheumatoid arthritis. The indication for surgery was pain in all but one. Outcome was assessed by the Mayo Elbow Performance Index (MEPI). Of the 59 arthroplasties, two were lost to follow-up. Ten patients died, but as two of their arthroplasties were failures we included them in the results. The outcome in the remaining 49 was excellent in 26 (53%), good in 15 (31%), fair in one (2%) and poor or a failure in seven (14%). There was an improvement in the pain score (p < 0.001), movement (p < 0.001) and function (p < 0.001). Two patients developed instability, but neither required further surgery. There was a mean increase of 21 degrees in flexion and of 7 degrees in extension. The overall rate of complications was 33.9%. Lesions of the ulnar nerve, one of which did not recover, occurred in four patients, deep infection in two and stiffness in five. The rates of complications were similar to those in recent reports of other elbow arthroplasties. We carried out a radiological analysis of 39 arthroplasties which showed radiolucent lines around the humeral component in 22 and the ulnar component in 15. There were lower scores on the MEPI for those with radiolucent lines around the humeral component.

Education and training opportunities in trauma and orthopaedics in SE Thames Region.

In preparation for the introduction of the specialist registrar grade the specialist advisory committee (SAC) in orthopaedics developed a six-year structured training programme leading to the award of the Certificate of Completion of Specialist Training (CCST). A team comprising the regional adviser in orthopaedics, the two regional programme directors and an associate dean of postgraduate medicine visited all the departments of orthopaedics in the South East Thames Region in order to evaluate the training opportunities they provided. This paper describes the methodology used during these visits, the lessons learned and the conclusions drawn.

Anterior interosseous nerve palsy and dislocation of the elbow.

A case is presented of an isolated anterior interosseous nerve palsy following posterior dislocation of the elbow. This has not previously been described. Full recovery occurred without operation. We have reviewed the literature and suggest a mechanism for this injury. The classification and treatment of the condition are discussed.

The value of low dosage heparin for the prophylaxis of thromboembolism in patients with transcervical and intertrochanteric femoral fractures.

One hundred and ten female patients, over the age of 60, with intertrochanteric or transcervical fractures were included in a controlled, randomized, clinical trial investigating the value of low dosage heparin in the prophylaxis of deep vein thrombosis. There were 50 completed pairs. Eight (16 per cent) deep vein thromboses occurred in the heparinized group compared with 23 (46 per cent) deep vein thromboses in the control group. The incidence of pulmonary embolism was also reduced. The diagnosis of deep vein thrombosis was made on clinical grounds, supplemented by phlebography and autopsy. There was no difference in the wound hematoma or infection rate. The heparin was commenced on admission to hospital and it is suggested that in this group of patients low dosage heparin prophylaxis should start on admission and not wait until surgery.

The Credit-Incentive system: motivating the participation of patients in a day hospital.

The Credit-Incentive System, a modified token economy, is a means of motivating the participation of day hospital patients in therapeutic activities through the use of contingent rewards. Credits are earned by patients for engaging in a wide variety of prosocial tasks and activities and can be spent for coffee, a free lunch, special time with professional staff, recreational events, and time off from the treatment centre. The receipt of credits is accompanied by social approval and recognition from the staff and other patients. Evaluations have shown that the credit system doubles the participation rate of patients in a partial hospitalization programme. The system also enhanced group cohesiveness, provides practice and feedback for cognitive re-integration, and offers opportunities of learning self-management. The results of two experiments suggest that the symbolic and social rewards mediated by the credits are the most important components of their effectiveness.
