East Lancashire Hospitals NHS

The aim of this qualitative interview study is to explore the unmet needs of patients who frequently attend the emergency department and the challenges of the staff who support them.
The study will interview 10 patients who frequently attend the emergency department and 10 staff members working within the emergency department.

Facial recognition is a non-invasive method for analysing facial characteristics and changes in facial expressions. There is evidence to suggest there may be a link between physiological health and facial expression patterns. Many medical conditions are associated with specific facial characteristics, with some related to inherited genetic conditions and others that have been acquired as a result of medical conditions such as stroke, nerve injuries and dementia. If successful, this technology could prove useful for studies evaluating the monitoring of acute or chronic illness. The proposed study will ask participants to do a maximal exercise test that will challenge the body, as a proof-of-principle, to see how this correlates with facial expressions. Depending on the study outcomes and future work, it could prove to be a useful tool and clinical application in healthcare for evaluating and tracking patient health and well-being. The investigators want to conduct a proof-of-principle study where physically stressed young and healthy participants (in the form of a maximal exercise test), whilst recording facial expressions, will be used to determine the relationship between physiological stress and changes in facial parameters.

1. FULL TITLE OF THE PROJECT Should we use post-operative antibiotics following surgery for patients with mandible fractures? The MANTRA trial (MANdibular TRauma and Antibiotic use)
2. SUMMARY OF RESEARCH (ABSTRACT) Research Question: Are post-operative antibiotics required following surgery for patients with mandible fractures? Background: Mandible fractures are the commonest facial fractures needing surgery and account for a significant percentage of the acute workload in Oral & Maxillofacial Surgery (OMFS) units. The UK records over 6000 new cases per year. Patients having surgery for mandible fractures have a theoretical risk of developing surgical site infection, due to the proximity of the fracture lines to the oral cavity microbes and the presence of foreign body (titanium fixation miniplates). For this reason, clinicians often prescribe antibiotics after surgery, to reduce the risk of infection. Previous systematic reviews and a multicentre cohort study performed by this team, revealed significant clinical variation in post-operative antibiotic prescription amongst UK OMFS clinicians and the presence of clinical equipoise. Antibiotic overuse can lead to antibiotic resistance and other antibiotic-related side effects; judicious antibiotic use and stewardship is of paramount importance.
Aim: To determine whether post-operative antibiotics are required at all, following surgery for mandible fractures, and, if so, what is the most clinically- and cost-effective regimen
Objectives:
Primary Objective To conduct a Randomized Controlled Trial (MANTRA) in order to establish the non-inferiority (or not) of not giving post-operative antibiotics versus 2 other post-operative antibiotic regimens. An internal pilot phase will optimise recruitment and retention.
Secondary Objectives
* Measure the cost-effectiveness of the proposed antibiotic pathways
* Assess patient and clinician acceptability to change clinical practice
* Process evaluation to inform dissemination and implementation Methods: The investigators designed and propose the MANTRA RCT to compare 3 post-operative antibiotic approaches to prevent Surgical Site Infections (SSIs) following surgery for mandible fractures. The MANTRA trial is a large open label, multicentre study in NHS OMFS units. The 3 study arms represent the most common clinical pathways in the UK based on previous work; the control group is the approach prescribed by most UK OMFS clinicians. All patients will receive 1 dose of IV antibiotics (co-amoxiclav 1.2g, if no penicillin allergy, which is the most commonly used prophylactic antibiotic currently) on induction of anaesthesia, prior to their surgery.
The participants will be randomised to the following (1:1:1):
Group A: No further antibiotics Group B: 2 further postoperative IV doses of co-amoxiclav 1.2g Group C: 2 further postoperative IV doses (as above), followed by a 5-day course of oral co-amoxiclav 625mg every 8 hours if no penicillin allergy (Control).
Trial processes will be optimised by an internal pilot phase ensuring we recruit, randomise, and retain participants with clear progression criteria. We will also conduct cost-effectiveness analyses and process evaluation for dissemination and implementation
Timeline:
Start of grant: 1st July 2023 Start of RCT / pilot: 1st January 2024 End of pilot: 30th June 2024 End of recruitment: 31st December 2026 End of follow-up: 30th June 2027 Completion: 31st December 2027
Impact and dissemination:
* Practice changing outputs that standardise the use of antibiotics in mandible fractures in the NHS and provide a framework for other surgical prophylaxis research
* A bespoke clinical dissemination plan via an engagement and training legacy
* Cost-effectiveness data to inform policy making
* A research legacy and change of culture in the specialty of OMFS
