Hip Fractures and the BOAST Standards

This piece is for general information and discussion only. It is not medical or legal advice.

Context

Hip fracture is one of the most common serious injuries affecting older women in the UK. It carries substantial risks, including loss of independence, complications and increased mortality. From a system perspective, hip fracture care reflects how reliably different parts of the NHS respond to urgent surgical need for frail older women.

The British Orthopaedic Association Standards for Trauma (BOAST), NICE guideline CG124, the National Hip Fracture Database (NHFD) and NHS England’s Best Practice Tariff together define what good hip fracture care should look like. These frameworks emphasise timely surgery, orthogeriatric review, effective pain control and coordinated rehabilitation.

Evidence and policy

National guidance

NICE recommends that adults with hip fracture receive surgery on the day of, or the day after, presentation unless there is a clear clinical reason to delay. It also emphasises delirium prevention, early mobilisation, bone‑health assessment and multidisciplinary care. BOAST aligns with this, expecting surgery within 36 hours where clinically appropriate and senior input across the pathway.

What UK audits show about timing and outcomes

UK audits consistently report that delays to theatre are associated with poorer outcomes. National analyses show that surgery within 48 hours is linked to lower 30‑day mortality than surgery performed later. NHFD‑linked work has examined thresholds at 24, 36 and 48 hours, showing that while illness severity can influence delay, longer waits generally correlate with higher mortality, complications and prolonged recovery.

Recent national reports show rising hip fracture volumes and a trend toward longer waits for surgery. Average waiting times have increased in recent years, and these delays are associated with functional decline and extended length of stay. UK audits distinguish necessary medical stabilisation from avoidable delay due to system pressures such as staffing, bed availability and theatre capacity.

National audit findings indicate that delays to theatre are associated with poorer outcomes, with studies showing that longer waits to surgery correspond to higher mortality and complication rates across UK datasets.

How timing influences outcomes

Evidence suggests several mechanisms through which delayed surgery worsens outcomes.

• Immobilisation and physiological stress. Longer pre‑operative waits increase the risk of respiratory complications, pressure damage, venous thromboembolism and deconditioning.
• Delirium risk. Pain, environmental stress and prolonged waits contribute to higher delirium rates, which reduce functional recovery.
• System effects. National analyses show variation by day and time of admission, indicating that capacity and workforce patterns influence timely access to theatre.

A recent review concluded that earlier surgery is generally associated with better outcomes, although some delays reflect unavoidable medical optimisation.

Presenting picture

Guidance highlights that clinicians typically assess for severe hip or groin pain after a fall, inability to bear weight and visible changes such as external rotation or shortening of the leg.

Older women may present atypically, particularly where frailty, dementia or communication difficulties are present.

Differential diagnoses can include pelvic or vertebral fractures, dislocation, soft‑tissue injury or medical causes of collapse.

National guidance emphasises prompt imaging, repeated assessment where suspicion remains high and early orthogeriatric involvement.

Guidance highlights that clinicians typically assess whether a person has sudden, severe pain in the hip or groin after a fall. Pain is usually worse when trying to move the leg or stand, and many people describe an immediate inability to bear weight. National recommendations also note that women may report deep, sharp pain radiating into the thigh or groin, sometimes accompanied by a sense that “the leg won’t hold.”

Because of muscle spasm and the way the bone shifts, the pain may become more intense with small movements such as turning in bed, being lifted onto a trolley or having clothes adjusted. In some older women, the pain can be less clearly described, especially where frailty, dementia or communication difficulties are present. Guidance stresses the importance of recognising that atypical descriptions do not rule out a fracture.

Physical findings that clinicians are expected to look for include:

• Pain on gentle rotation or lifting of the leg
• Pain when the heel is tapped
• Marked discomfort on any attempt to stand or take weight
• External rotation or shortening of the affected leg

National guidance also emphasises that hip fractures can occasionally present with diffuse lower‑back or pelvic pain, particularly in women with osteoporosis, meaning the pain does not always feel as “localised” as expected. In these situations, clinicians are expected to maintain suspicion and arrange timely imaging.

Investigations repeatedly note that women often report:

• Long waits before pain relief is provided
• Pain worsening during prolonged time on trolleys
• Difficulty having the severity of pain recognised, especially where they cannot articulate symptoms clearly
• Pain that feels “deep,” “grinding,” or “as if the leg won’t move properly”

In short, the typical picture is severe hip or groin pain that worsens with movement and prevents weight‑bearing, with acknowledgement that older women, especially those living with frailty or cognitive impairment, may present with less specific but equally significant pain.

What reviews say women often describe

National reviews and investigations frequently report women saying that pain relief was delayed or inconsistent, the severity of symptoms was not always recognised and explanations about any surgical delay were unclear. Moves between emergency care, orthopaedics and geriatrics often felt fragmented. Women also described limited discussion of falls risk or bone health before the fracture occurred.

System watchpoints

This section highlights system patterns seen in research, guidance and investigations. It is not medical or legal advice, and it is not a checklist for your own care.

Who the evidence represents

NHFD captures nearly all people aged 60 and over admitted with hip fracture, creating a robust dataset. However, women with learning disabilities, from minority ethnic communities or experiencing socioeconomic disadvantage remain under‑represented in published analyses.

Pain and documentation

Investigations report variation in pain assessment and the use of nerve blocks. Documentation of analgesia timing and effect remains inconsistent.

Theatre access and weekend capacity

Variation exists in access to theatre depending on day and time. Some delays reflect systemic capacity constraints rather than clinical need.

Medical optimisation versus delay

UK audits highlight the need to differentiate necessary clinical stabilisation from avoidable system delays, especially around bed flow and theatre scheduling.

Transitions of care

Transitions between emergency departments, orthopaedics, geriatrics and rehabilitation present recurring risks, including inconsistent discharge planning and limited clarity about mobility status and bone‑health interventions.

What is improving

• Increasing survival rates and stronger orthogeriatric services.
• Wider use of NHFD data to monitor time to theatre and early mobilisation.
• Greater focus on delirium prevention and bone‑health management.
• More consistent adoption of NICE and BOAST timing standards.

Where further improvement might come from

• Reducing variation in theatre access through improved staffing models and protected trauma lists.
• Trauma‑aware communication, especially for women with cognitive or sensory challenges.
• Strengthening midlife osteoporosis and falls‑prevention pathways.
• Better digital documentation of pain relief, time stamps and mobilisation milestones.
• Continued transparency in audit and use of patient‑reported experience measures.

Questions for readers (off‑blog)

For clinicians and managers:

How consistently are NICE and BOAST timing standards achieved?
How is medical optimisation differentiated from avoidable delay?
How well are communication needs recognised and supported?
What patterns appear in your data around night‑time and weekend surgery?
How effectively is discharge coordinated with community rehabilitation and fracture liaison?

For patients and carers:

How clear were explanations about surgery and any delays?
Was pain relief timely and effective?
Did staff understand your usual mobility and home environment?
How coordinated did care feel between departments?
Were bone health and future fracture risk discussed before discharge?
