Plain English Summary

Background and study aims
This study has been designed following a James Lind Alliance Patient and Public Research Priority Setting Partnership, which identified the following question as a top research priority: “What are the best treatments to prevent and treat confusion and delirium after surgery in adults with a broken bone in the leg?” The study has been co-produced with the UK Musculoskeletal Trauma Patient and Public Involvement Group.

A broken hip (hip fracture) is a very serious injury that requires surgery to repair or replace the broken bone followed by a long period in hospital to recover. Around a quarter of patients with hip fracture die within a year and those that survive have a permanent loss of their quality of life. Worldwide there are 1.3 million hip fractures each year, with more than 70,000 in the UK.

Around a quarter of patients who have a hip fracture have an episode of ‘delirium’ after their surgery. Delirium is a condition where the patient loses awareness of themselves and their environment, and has difficulty thinking clearly. For relatives and friends, as well as the patient, delirium is very disturbing. The symptoms of delirium are similar to those of patients with dementia but develop over a short period and tend to vary over time. The great majority of patients suffering with delirium recover quite quickly, but delirium leads to longer hospital stays and a greater risk of complications. Delirium is also associated with an increased risk of developing dementia in later life.

Inflammation, caused by the hip fracture and by the surgery to repair the hip, is thought to be the root cause of delirium. This study will investigate the use of a drug called ‘lidocaine’ to see if it reduces the risk of delirium after surgery for a hip fracture. Lidocaine is already used very widely in the NHS as a local anaesthetic, but it also has a strong anti-inflammatory effect. If lidocaine is given to a patient during surgery to reduce inflammation, it may reduce the severity of delirium after surgery.

Who can participate?
This study falls under the WHITE Platform framework and is open to all patients aged over 60 years with a hip fracture, apart from the very small number of patients who have an allergy or another reason not to have lidocaine. Eligible patients will be approached about the study before their treatment where possible. Patients who are unable to consent for themselves may take part in the trial with the agreement of their relatives or an independent doctor, who will be known as legal representatives.

What does the study involve?
Patients from at least 12 hospitals in the UK will be approached to take part in the study. 416 participants will take part. Half will be allocated by chance to a slow injection of lidocaine during their surgery, and half to a placebo injection containing no lidocaine. Neither the patients nor their doctors will know which treatment they had to make the study fair. All other elements of the patients’ treatment will follow the normal care pathway for all hip fracture patients at the hospital.

We will use a series of simple questions to measure symptoms of delirium in the first five days after surgery. We will also assess the patients’ mobility, quality of life and complications and review if they develop symptoms of dementia in the 12 months after surgery. We will also work out the cost of the treatment – for the individual, for the health service and in terms of social support in the year following the fracture. We will also ask people for their permission to monitor their long-term health outcome from national databases that are already being routinely collected. Any information collected from these databases will not contain any details which could identify the patient.

What are the possible benefits and risks of participating?
The risks of hip surgery include infection, blood clots, chest or urine infection - these risks are the same as for people who are not part of this research project.
The risks associated with intravenous lidocaine include minor symptoms such as tingling of the lips. More serious effects such as disturbances of heart rhythm can occur but are very unlikely at the doses used in this treatment comparison. Patients will have continuous monitoring whilst the lidocaine is being given, and an emergency treatment to reverse these effects is available. Lidocaine has been used safely like this in other types of surgery for many years.

Scientific titleWorld Hip Trauma Evaluation - LIT: Lidocaine Intravenous Trial
Study acronymWHITE 10-LIT
Study hypothesisTo establish if there are differences in peak delirium in the 5 days following hip fracture surgery between hip fracture patients receiving a peri-operative lidocaine infusion or a saline placebo infusion.
Ethics approval(s)Approved 14/01/2021, Berkshire Research Ethics Committee (Berkshire South Central REC, Easthampstead Baptist Church, Southill Road, Bracknell, RG12 7NS, UK; +44 (0)2071048138; berkshire.rec@hra.nhs.uk), ref: 20/SC/0452
ConditionHip fracture
InterventionWHiTE 10-LIT is a randomised comparison appended to the World Hip Trauma Evaluation (WHiTE ) Platform. WHiTE is a platform trials framework, designed to efficiently deliver multiple randomised comparisons of interventions for patients aged 60 years and over with a hip fracture. The platform and its appended randomised comparisons are governed by one single set of ethical and regulatory approvals and an explicit legal basis and processing purpose for the use of patient-level data. The Platform affords a common core dataset and documentation.

Individual randomised comparisons are not dependent on each other and each will have its unique start and stop dates and publication of results without compromising the integrity of the platform.

Participants will be randomised on a 1:1 basis to lidocaine or placebo infusion, stratified by presence of cognitive impairment at presentation and recruitment centre:
1. Intervention: Intravenous lidocaine 1.5 mg.kg-1 bolus followed by infusion of 1.5 mg.kg-1.h-1 for the duration of surgery
2. Placebo control: Identical volumes of 0.9% saline

The allowed maximum absolute dose will be 120 mg and 120 mg h-1 regardless of weight.

Randomisation will be on a 1:1 basis to lidocaine or placebo, stratified by the presence/absence of permanent cognitive impairment at presentation and recruitment centre. The allocation sequence will be generated by the trial statistician using variable block sizes and stored securely in a web-based encrypted system provided by the CTU.

An appropriately trained individual other than the treating clinician or anyone involved in the assessment of any trial outcomes will carry out the online randomisation and prepare a syringe with the allocated intervention, in an area away from the clinical team. The prepared syringe will then be labelled ‘lidocaine 1% or saline 0.9%’ so as not to reveal the treatment allocation to the treating anaesthetist when they administer it to the participant in order to ensure that the patient is not treated differently during the surgery. Lidocaine and saline are clear colourless solutions, indistinguishable to the human eye.
