Chapter 16: Guidelines for the Provision of Anaesthesia Services for Trauma and Orthopaedic Surgery 2020
Trauma remains the most common cause of loss of life in the under 40s age group1 in the UK, and as such major trauma centres (MTCs) and trauma units (TUs) have been established to receive patients of all ages, and improve outcomes. Early anaesthetic involvement is beneficial at all stages, from the prehospital setting, to emergency departments (ED), operating rooms, interventional radiology suites, postoperative care units and the critical care environment. The need for significant anaesthetic input and support for these complex patients is an integral part of this pathway.
MTCs and TUs should have major incident plans in place to deal with mass casualties from any cause.
Primary arthroplasty surgery significantly improves the quality of life and the mobility of those affected. With the advancing age of our population and their increasing expectations, the number of patients requiring primary arthroplasty surgery and subsequent revision arthroplasty surgery continues to escalate. This population is frequently elderly with co-existing medical conditions that need to be optimised prior to surgery, and benefits from a multidisciplinary team (MDT) approach and the use of standardised protocols.
Hip fracture is the most common condition presenting for emergency orthopaedic surgery in the UK with many patients aged over 65. These patients along with those requiring surgical intervention for fragility fractures present significant challenges and the input from a multidisciplinary team and early surgery is essential to achieve good outcomes in this population.
Orthopaedic surgery in children ranges from closed fracture manipulation and casting, to complex long bone or spine correction of congenital or acquired conditions. These may be associated with neurological conditions, or specific syndromes that could pose challenges to those providing anaesthesia care.
1. Staffing requirements
Appropriate levels of staffing are essential to deliver high quality anaesthetic input into trauma and orthopaedic patients. The challenge is providing the right people at the right place at the right time. Trauma care can be particularly difficult as it occurs frequently out of hours, and may present with multiple casualties at any time.
Each unit should have a designated clinical lead (see glossary) for anaesthesia services for trauma and a designated lead for anaesthesia services for orthopaedic surgery. This should be recognised in their job plan and they should be involved in multidisciplinary service planning and governance within the unit.
Anaesthetists with a specific interest in orthopaedics and trauma should deliver regular theatre sessions to ensure the maintenance of their skills and experience.
All patients undergoing anaesthesia should be under the care of a consultant anaesthetist whose name is recorded as part of the anaesthetic record.2,3,4 A staff grade, associate specialist and specialty (SAS) grade anaesthetist could be the named anaesthetist on the anaesthetic record if local governance arrangements have agreed in advance that, based on the training and experience of the individual doctor and the range and scope of their clinical practice, the SAS anaesthetist can take responsibility for patients themselves in those circumstances, without consultant supervision.
Theatre staff should be available who are appropriately trained, skilled and experienced in the various surgical specialties that may present in the treatment of patients with multiple injuries.
Anaesthesia for the emergency control of major traumatic haemorrhage, and other damage limiting interventions in the operating theatre or radiology intervention suite, should be consultant anaesthetist led. Where consultants are not resident, clear lines of communication and notification should be in place to allow early attendance to trauma calls.
MTC and TU anaesthetic departments should consider appointing anaesthetists with an interest in prehospital care. Anaesthetists who provide prehospital care in the field should be qualified to do so.5
Emergency department (ED)
Major trauma patients arriving in the ED of MTCs and TUs should be met by a multidisciplinary team 24/7. An anaesthetist with appropriate airway and damage control resuscitation competencies to manage trauma patients should be part of this team.6
Whenever possible, trauma team members should be called in advance of the patient’s arrival to allow time for briefing, and drug and equipment preparation. The team should also assemble before inter-hospital trauma transfer, allowing the transfer of imaging and treatment plans to be defined in advance.
The transfer of trauma patients to a MTC will normally be facilitated by the referring hospital. The referring hospital should have robust arrangements in place to enable this to occur safely without compromising clinical activity at their base hospital.10
There should always be an adequate number of staff to ensure safe transfer and positioning of anaesthetised patients.
Patient positioning during transfer should be discussed at the team brief and the relevant lead person identified.
Elderly patients presenting for elective surgery frequently have pre-existing comorbidities that require careful review and perioperative planning. As such, the preassessment service for elective patients should be consultant led, ideally by anaesthetists with an interest in, and appropriate experience in, delivering anaesthetic care to orthopaedic patients.11,12
Anaesthetists should be involved alongside surgical colleagues and orthogeriatricians, in discussions on preoperative planning, timing of surgery, and postoperative care, especially for high risk patients.
2. Equipment, services and facilities
A range of operating tables with attachments for spinal, thoracic, pelvic and limb trauma procedures should be available.
Tourniquets and inflation devices of suitable sizes should be available for upper and lower limb surgery requiring a bloodless field.
Equipment to facilitate haemodynamic and cardiac output monitoring should be available.
A ‘difficult airway trolley’ should be immediately available in all areas where major trauma patients are received. These should be equipped as defined in the Difficult Airway Society (DAS) guidelines, and include video laryngoscopes, fibreoptic scopes, jet ventilation and surgical airway equipment.9,21,22
In MTCs and TUs, the resuscitation room receiving bays should be large enough to allow simultaneous emergency procedures to be performed by trauma team members.31
Hospitals that receive patients with major trauma should ideally have an emergency operating theatre and a radiology intervention suite situated sufficiently close to the ED to allow rapid transfer of trauma patients.
An emergency operating theatre should be rapidly available at all times for major trauma patients. The available equipment should be suitable for a full range of emergency trauma procedures. Use of this theatre for non-urgent cases should be tightly controlled. If the designated emergency theatre is occupied, there should be a robust, flexible and agreed backup plan to obtain an appropriate alternative theatre for the next emergency case.
MTCs receiving major trauma patients should have a trauma theatre equipped with a radiolucent operating table that allows fluoroscopic imaging of all body parts without repositioning the patient.
Primary and revision arthroplasty surgery, along with trauma surgery involving bone implants or internal fixation should be carried out in an operating theatre with multiple air changes per hour (e.g. laminar flow).
Point of care testing for haemoglobin, blood gases, lactate, ketones, coagulation, viscoelastic measurements and blood sugar should be available during surgery for patients with major trauma and those undergoing orthopaedic procedures associated with a risk of haemorrhage.23 If near-patient testing is not available, laboratory testing should be readily and promptly available.
In MTCs with a high volume of patients, prethawed plasma should be immediately available.
In MTCs and TUs there should be a rapidly accessible imaging suite for patients with major trauma, which is equipped with all of the life support facilities available in the emergency room. This will include physiological and gas monitoring; in addition, the room design should allow visual and technical monitoring of the patient by the anaesthetic staff.31
An imaging suite for interventional radiology to control haemorrhage should be available in MTCs. This will ideally be a hybrid care suite that allows a full range of surgical interventions as well as radiological assessment.30
Exposure to ionising radiation should be minimised by the use of screens or radiation protection garments and remote slave monitors in screened viewing areas. Staff should remain as distant from the imaging source as possible if they must remain in the x-ray environment.33
Hospitals admitting patients with major trauma should have critical care to both Level 2 and 3 standards on site.29 Portable invasive haemodynamic monitoring should be available to facilitate transfer to and from the critical care areas.
A fully equipped high dependency unit (HDU) of Level 2 standards should be available on site for high risk patients undergoing major orthopaedic surgery, including revision joint replacement and surgery involving instrumentation of the spine. If the hospital does not have a Level 3 facility, protocols should be in place to determine when and how to transfer to a hospital with a Level 3 facility.
Critical care outreach services should be considered to provide a vital link between trauma and orthopaedic wards and intensive care unit (ICU) facilities. Clinical deterioration can be identified using early-warning scores and mitigated by proactively reviewing patients at risk.
3. Areas of special requirement
The definitive care of complex spinal and pelvic injuries requires specialist spinal (orthopaedic or neurosurgical) and pelvic surgery. The anaesthetist managing such cases should have appropriate training and experience in the management of these cases and their associated complications.
Clear protocols should be in place for the management of cases of suspected spinal injury. This should include a spinal clearance policy.32
Immobilisation equipment including a range of appropriately sized semi rigid collars, head blocks, tape, a vacuum mattress and a scoop board should be available.
Spinal clearance should be achieved as soon as clinically possible, to minimise discomfort and complications from prolonged immobilisation in patients who do not have spinal injuries.
Patients presenting with a neurological deficit should have immediate referral to a specialist unit and be discussed with the neurosurgical or spinal surgeon.
In suspected spinal injury, hard spinal boards should only be used as a prehospital extrication device and not be used for transport.31 A scoop stretcher or full length vacuum mattress should be used for transfer.
Acute nerve or spinal cord compression requires immediate referral to a neurosurgeon or specialist spinal surgeon within four hours of injury.37
Anaesthetists will often be part of the MDT responsible for the initial resuscitation and stabilisation of the critically ill or injured child, prior to transfer to a specialist centre.
All hospitals with an ED will be exposed to high volumes of paediatric patients with low velocity injuries requiring orthopaedic input.
Standards for children’s services described in chapter 10 should be followed.
It is essential to be vigilant for non-accidental injury in children with trauma injuries.
Pregnant trauma patients
Although the primary duty of care is to the mother, fetal and maternal wellbeing are inextricably linked. Standards for non-obstetric emergency procedures in pregnant patients are described in chapter 5.
Patient positioning for elective and trauma orthopaedic surgery involves a variety of specialist equipment, tables and attachments. These should be suitable to manage patients across a wide weight range, with theatre personnel aware of the upper weight limits.44
The majority of hip fracture patients are >65 years of age and often have multiple comorbidities, some of which may be undiagnosed. Decisions on their treatment should ideally be made using a multidisciplinary team that involves senior anaesthetists, perioperative physicians, orthopaedic surgeons and orthogeriatricians, all with a specific interest in this patient population.45
Unoperated hip fractures in the elderly have a higher mortality rate. Evidence shows ASA4 patients have a higher survival rate when managed surgically.47 Hip fracture surgery should be considered for patients even in the presence of significant comorbidities. Provision for safe anaesthesia and recovery of these patients, including handover to ward teams, should be available to facilitate this.
A fall of <2m is the commonest mechanism of injury in older patients. Prehospital triage to aid early identification of severe injuries in older patients should be available to allow quick transfer from TU to a MTC for specialist investigation and intervention.48
Compehensive geriatric assessment and frailty screening tools may facilitate more informed early decision making in older trauma patients.49 Protocols for end of life care should be in place for management of elderly patients with frailty that may prove unsurvivable days or weeks after the initial trauma by a multidisciplinary team.50
Units should use a delirium assessment tool and have a delirium policy describing preventative measures and its management.51
4. Training and education
All anaesthetists providing anaesthesia for trauma and orthopaedics should have appropriate knowledge, skills, attitudes and behaviour in accordance with the RCoA training standards.
Anaesthetists with responsibility for the intraoperative care of trauma patients should ensure that their skills and knowledge of current recommendations are up to date, particularly in the management of major haemorrhage.
Anaesthetists who manage patients with major trauma should consider undertaking advanced trauma life support (ATLS), European Trauma Course (ETC) or equivalent training, and should update their training at regular intervals.
Anaesthetists providing anaesthesia for trauma and orthopaedic surgery should learn and maintain expertise in a wide range of regional anaesthetic techniques, including central and peripheral neural blockade.52
All anaesthetists involved in the management of major trauma should understand the principles and techniques of damage control resuscitation to prevent lethal triad of hypothermia, acidosis and coagulopathy using low volume fluid resuscitation, blood products and damage control surgery.
Anaesthetic trauma theatre teams should be trained in the correct use of all essential anaesthetic theatre equipment used for trauma surgery.
Staff in the recovery area and in the wards who receive patients after surgery with epidural infusions, nerve blocks or intravenous opioid infusions (including patient controlled analgesia) should have received up to date formal training in caring for these forms of analgesia.
Anaesthetic staff expected to care for patients with epidurals and continuous nerve blockade in situ should be trained to local guidelines before they top up medication or care for such patients.
Anaesthetic practitioners involved in the administration of anticoagulant therapies should have current and up to date knowledge in their use.
There should be regular multidisciplinary in situ simulation training for the initial management of major trauma care and resuscitation to standardise clinical practice.
Awareness of regional analgesia benefits in chest trauma and early referral to acute pain services should be emphasised within the multidisciplinary trauma team.53
The diagnostic and therapeutic applications of POCUS in trauma are expanding. There is a need for emphasis on quality training of POCUS operators within the trauma multidisciplinary team.54
Major incident training exercises should take place at regular intervals.
Educational opportunities for trainees in MTC and TU will undoubtedly occur out of hours due to the nature of trauma. Hospitals in which trainee anaesthetists work a full or partial shift system should consider providing additional consultant programmed activities to allow training and supervision to take place in the evening.
Hospitals should consider training of ED staff in acute pain management of both adult and paediatric patients with trauma, in particular using ultrasound-guided femoral nerve block or fascia iliaca block for hip fractures in elderly patients and femoral fractures in children.
5. Organisation and administration
The goal of trauma surgery is to provide definitive fixation to all indicated fractures at the earliest possible opportunity. However, due to associated injuries, or availability of specialist surgeons, this is not always possible. Definitive surgical fixation may have to be approached in a planned, staged response. Equally, patients who become unstable intraoperatively may require a change to the initial surgical plan. Understanding and implementation of locally agreed protocols along with good communication is paramount to its success.
Emergency orthopaedics and trauma
A triage tool, similar to that developed by the American College of Surgeons, should be used to identify patients with suspected major trauma prehospital.32
Triage positive patients should be sent directly to an MTC if the travelling time is <60 minutes (or 45 minutes if agreed by the trauma network), unless there is an imperative to go to a closer TU for the immediate management of a life threatening condition.32
Triage positive patients should not be taken to a local emergency hospital (LEH), in other words an acute hospital not accredited as a TU or MTC.32
The trauma team should attend in cases of suspected major trauma according to predefined local criteria. The trauma team should also be called out if there are unexpected findings after arrival in triage-negative patients, and to receive patients following interhospital transfer.
There should be a local protocol for immediate or emergency access to an operating theatre or intervention suite, with appropriately trained and experienced staff to provide rapid intervention in life threatening or limb threatening conditions.32
Dedicated trauma operating lists, staffed by trauma teams should be scheduled daily, enabling maximal efficient use of theatres. This includes the provision of extra trauma lists in the evenings and at weekends. These measures aim to limit overnight operating, with less experienced staff and limited postoperative care facilities.
There should be a flexible approach to trauma list planning and management to allow for interruption from emergency cases.59 Theatre teams should be informed whenever an unstable patient with major trauma is expected, has arrived or has been identified in the ED. The practitioner in charge of the trauma theatre team should have responsibility for ensuring the availability of appropriately trained staff and facilities to receive these patients.
All acute hospitals should have a defined major incident plan. The plan should be built around the network of MTCs, TUs and LEHs. A prehospital triage tool should be used to determine where patients should be taken.60
Rapid and effective communication between healthcare professional and the individual are key to good patient care, not only for initial management but for for the whole of the recovery trajectory. Communication strategies should consider the use of new technologies, e.g. smart phones, and standardised methodology.63,64
Elective orthopaedic operating lists should be separated from those for trauma orthopaedic surgery, to allow efficient planning, prevent cancellation and enable a flexible response for emergencies.
Elective patients with major comorbidities or those undergoing complex or prolonged surgery should be scheduled earlier in the day, to allow time for postoperative stabilisation.
Hospitals should consider providing specific regional anaesthesia lists, using dedicated areas for performing peripheral nerve blocks. Cohorting cases in this way optimises theatre efficiency, reduces block failure65 and creates the environment for developing expertise.
There should be a preoperative assessment clinic for elective orthopaedic surgery. Evidence supports multidisciplinary preassessment and optimisation improves perioperative outcome for joint revision66 and scoliosis surgery.
There should be specific guidelines for assessing a suspected difficult airway in patients with spine and joint disease, and for measuring lung function in patients with kyphoscoliosis.67
There should be a robust procedure in place to check the specific site of surgery before anaesthesia is administered.70 This should include identifying laterality of limbs and use of an indelible mark by the responsible surgical team prior to admission to the operating theatre.
Isolated elective orthopaedic units performing major inpatient surgery should have 24/7 access to all support services including acute pain services and critical care. Local guidelines should be in place to provide safe anaesthesia care which includes preassessment screening for risk stratification, transfer criteria and postoperative care facilities.
Preoperative assessment should identify people with cognitive impairment. The anaesthetic risk should be explained including measures to minimise cognitive changes.The carers should be involved in all stages of perioperative care and invited to accompany with the person into the operating room before and after surgery. People with dementia are often frail and should be assessed using a validated scoring system and managed accordingly.71
Hospitals providing surgical treatment for hip fractures should have a formal pathway including prompt provision of analgesia (including nerve blocks when appropriate) and hydration, preoperative assessment of high risk patients by the anaesthetic team, along with, orthogeriatrician input and be prioritised on orthopaedic trauma lists.13,72,73,74,75
Agreed local guidelines should be in place and implemented on the following:
- compliance with best practice anaesthetic management protocols for hip fracture as recommended by the Association of Anaesthetists13
- tailored World Health Organization (WHO) safety checklists to identify the potential for adverse events associated with the requirement for use of bone cement should be used during team briefing and at time out
- preoperative assessment fitness criteria for hip fracture surgery and review of ‘do not attempt cardiopulmonary resuscitation’ (DNACPR) status.
Regional anaesthesia and analgesia
Agreed local guidelines should be available which have been produced by a multidisciplinary team including an anaesthetist, acute pain nurse, pharmacist, physiotherapist, critical care clinicians, surgeons and other relevant specialties.8 These guidelines should cover at least the following:
- protocol for whom to call for problems with postoperative pain relief
- management of complications including high spinal block, accidental dural puncture and nerve injury
- assessment and management of local anaesthetic systemic toxicity and peripheral nerve injuries
- supervision and monitoring of patients by competent clinical staff during surgery performed under peripheral regional anaesthesia and in block room or similar facility
- checklists to prevent wrong site nerve blocks in theatre and other clinical areas70,76,77,78
- anticoagulation guidelines for safe placement of epidural and regional nerve block techniques81
- preoperative screening for complex pain issues and access to acute pain services and advanced pain management methods
- post procedure monitoring of epidurals, nerve blocks and continuous infusion analgesia on the ward, including follow up care in hospital and after discharge
- recognition and management of patients at risk of acute compartment syndrome
- pain management pathway for chest wall injuries including provision for early epidural or nerve blocks in patients with multiple rib fractures as recommended by BOAST 15 blunt chest wall trauma guideline.79
For ongoing management of major trauma patients there should be clear guidelines regarding decisions to transfer for definitive specialist intervention in co-ordination with regional trauma networks.60
In MTCs and in other large acute hospitals, prethawed plasma should be immediately available with the initial shock pack.
There should be clear guidance on damage control resuscitation which is understood by all staff.71
There should be clear guidelines on how to manage patients on anticoagulant therapy presenting with trauma or for elective orthopaedic surgery. Specific reversal agents may be required, such as prothrombin complex concentrate in the trauma setting in patients on warfarin. Direct oral anticoagulants (DOACs), patients on dual antiplatelet therapy (DAPT) and second generation drug eluting stents (DES) all require careful consideration and timing for surgery, both emergency and elective.82
There should be a policy for the prevention of thromboembolic events postoperatively. This should include planning for anticoagulant prophylaxis in patients who are vulnerable to further bleeding.
All hospitals providing joint replacement surgery should have clear guidelines for enhanced recovery in place, in order to promote the benefits of early mobilisation and reduced mortality associated with their use.
Consultant anaesthetists and intensivists should be involved in the planning of local trauma services. Those with defined responsibility for major trauma management should be engaged in the layout and logistics of the resuscitation room.
In MTCs, multidisciplinary mortality and morbidity meetings should take place and follow the guidance of the World Health Organization (WHO).84
Governance meetings should take place across the entire trauma network at defined intervals. Besides individual case discussion, feedback information from the Trauma Audit and Research Network (TARN)1 should be disseminated, and mechanisms set in place to correct any problems identified.
6. Financial considerations
Part of the methodology used in this chapter in making recommendations is a consideration of the financial impact for each of the recommendations. Very few of the literature sources from which these recommendations have been drawn have included financial analysis.
The vast majority of the recommendations are not new recommendations, but they are a synthesis of already existing recommendations. The current compliance rates with many of the recommendations are unknown, and so it is not possible to calculate the financial impact of the recommendations in this chapter being widely accepted into future practice. It is impossible to make an overall assessment of the financial impact of these recommendations with the currently available information.
7. Research, audit and quality improvement
Research in anaesthesia for trauma and orthopaedic surgery should be encouraged. Staff undertaking research should have received training on ethical and organisational issues. They should complete a good clinical practice course with regular updates.
Trauma and orthopaedic surgery should be included in anaesthetic departmental audit programmes, including ongoing audit of complications and adverse events. The trauma anaesthetists should have provision in their job plan to attend trauma MDT meetings for discussion regarding high risk patients.
All hospitals treating patients with hip fractures should participate in national audits, e.g. National Hip Fracture Database or the National Joint Registry76,77 to monitor its performance against national benchmarks and quality standards. Outcomes from these audits should be distributed to anaesthetic staff.
All hospitals receiving major trauma cases should contribute to TARN,1 to monitor its performance against national benchmarks and quality standards and contribute to research. Comparative data analysis and display on the national major trauma dashboard (via TARN) is invaluable for quality assurance.
There should be clear processes and policies for reporting and learning from near misses and critical incidents. National patient safety alerts should be communicated and actions agreed locally to reduce the risk of harm.
Nationally agreed key performance indicators should be used to monitor the performance of the pathways for hip fractures and major trauma and reviewed by a multidisciplinary committee including a Trauma Lead anaesthetist. In addition, local quality indicators should be developed proactively, to support continuing improvement of these services within organisations.
8. Implementation support
The Anaesthesia Clinical Services Accreditation (ACSA) scheme, run by the RCoA, aims to provide support for departments of anaesthesia to implement the recommendations contained in the GPAS chapters. The scheme provides a set of standards, and requires departments of anaesthesia to benchmark themselves against these using a self-assessment form available on the RCoA website. Every standard in ACSA is based on recommendation(s) contained in GPAS. The ACSA standards are reviewed annually and republished approximately four months following GPAS review and republication, to ensure that they reflect current GPAS recommendations. ACSA standards include links to the relevant GPAS recommendations, for departments to refer to while working through their gap analyses.
Departments of anaesthesia are given the opportunity to engage with the ACSA process for an appropriate fee. Once engaged, departments are provided with a ‘college guide’, either a member of the ACSA committee or an experienced reviewer, to assist them with identifying actions required to meet the standards outlined in the document. Departments must demonstrate adherence to all ‘priority one’ standards listed in the document to receive accreditation from the RCoA. This is confirmed during a visit to the department by a group of four ACSA reviewers (two clinical reviewers, a lay reviewer and an administrator), who submit a report back to the ACSA committee.
The ACSA committee has committed to building a ‘good practice library’ (GPL), which will be used to collect and share documentation such as policies and checklists, as well as case studies of how departments that have overcome barriers to implementation of the standards, or have implemented the standards in innovative ways.
One of the outcomes of the ACSA process is to test the standards, and by extension the GPAS recommendations, to ensure that they are able to be implemented by departments of anaesthesia and consider any difficulties that may result from implementation. The ACSA committee has committed to measuring and reporting feedback of this type from departments engaging in the scheme back to the CDGs updating the guidance via the GPAS technical team.
9. Patient information
Information for patients, relatives and carers
Patient information leaflets on hip fractures should be available for patients, relatives and carers.46
For patients with complex trauma, including spinal cord injuries and traumatic brain injury, there should be rapid access to key professionals and regional specialists.37 Patients, relatives and carers should be directed to appropriate support groups where relevant e.g. the Spinal Injuries Association.92
Enhanced Recovery Programmes for patients undergoing primary arthroplasty surgery should provide comprehensive details of the patient journey including MDT led hip and knee school and expectations in terms of early mobilisation postoperative physiotherapy. Information provided should be comprehensive and include details of regional anaesthesia.
In order to give valid informed consent, patients need to understand the nature and purpose of the procedure. Full guidance, including on providing information to vulnerable patients, can be found in chapter 2.
Informed consent may not be possible for many patients undergoing hip fracture and major trauma surgery, owing to delirium, dementia, altered conscious level, severe pain or the effects of sedative drugs. Patients should not be asked to sign a consent form if they do not have capacity to do so. Standard operating procedures must be compliant with the Mental Capacity Act 2005. A high level of integrity should be maintained, and good documentation is essential.11,93,94,95
End of life care
Early communication with patients and their families is essential. On occasions, explanations and detailed discussion should be deferred or delegated to others, so that emergency treatment can proceed without delay.
When it is considered appropriate for a do not to attempt resuscitation in the event of a cardiopulmonary arrest (DNACPR) order, it should be discussed with capacitous patients, including those who have expressed their own wish not to be resuscitated.96,97 In patients not capacitous to consent, every attempt should be made to discuss this with next of kin and/or patient advocates holding power of attorney (or an independent mental capacity advocate), according to local trust guidelines.
Areas for future development
Following the systematic review of the evidence, the following areas of research are suggested:
Prehospital care - Auditing longterm outcomes on fractured neck of femur and revision of major joint surgeries using a validated objective tool.
Clinical lead - SAS doctors undertaking lead roles should be autonomously practicing doctors who have competence, experience and communication skills in the specialist area equivalent to consultant colleagues. They should usually have experience in teaching and education relevant to the role and they should participate in Quality Improvement and CPD activities. Individuals should be fully supported by their Clinical Director and be provided with adequate time and resources to allow them to effectively undertake the lead role
Triage positive – Identified as severe injuries by the ambulance team using prehospital triage system.
Triage negative – Not identified as severe injuries by the ambulance team using prehospital triage system.
