New research from the Royal College of Anaesthetists (RCoA) and the University of Nottingham reveals that nearly three-quarters (71%) of UK hospitals are not routinely screening older surgical patients aged 60 and older for frailty—despite clear evidence that frailty significantly increases the risk of complications, including longer hospital stays, delirium, and even death.
One in five (19.6%) surgical patients over 60 are living with frailty— a condition that can lead to slower recovery from illness or injury. Many affected patients will not know that they have the condition or how it can affect their recovery from surgery.
The researchers recommend that all patients over 60 are assessed for frailty before surgery as standard practice so that their care can be managed, with involvement from a geriatrician where appropriate.
The research, published in the British Journal of Anaesthesia, is from the RCoA’s third Sprint National Anaesthesia Project (SNAP3), the most comprehensive study on frailty and multimorbidity in UK surgical patients to date, and includes data from 7,134 patients across 263 NHS hospitals collected over five consecutive days in March 2022.
People living with frailty are less likely to recover well from an operation and the risks increase the more frail someone is. Compared to patients who are not frail, people living with frailty:
- Stay an average of three days longer in hospital after an operation, increasing to six days longer for those who are severely frail.
- Are three times more likely to have complications from surgery.
- Are four times more likely to have delirium following surgery, a condition that causes confusion.
- Are three times more likely to die within one year of surgery.
People living with frailty might notice feeling slower, weaker, or more tired. They may also notice muscle loss, unintentional weight loss, and a greater need for help with daily tasks.
The Clinical Frailty Scale (CFS) is a straightforward tool that can be used by healthcare professionals to identify whether a person is living with frailty. A CFS score of 5 or more indicates frailty and should prompt referral to a geriatrician for specialist care.
Identifying patients living with frailty helps healthcare professionals discuss individualised treatment options. This includes realistic discussions about the likelihood of survival and of remaining independent after the operation. It also helps hospitals to reduce risks, improve recovery, and provide the right support after surgery.
However, these discussions can only take place if frailty has been identified. The research shows in nearly three-quarters (71%) of cases UK hospitals are not routinely screening for frailty.
This collaborative study, delivered by anaesthetists from almost every hospital in the UK, has highlighted just how common frailty is in older people having surgery. Identifying frailty is straightforward and should lead to open and honest discussions with patients about what can be offered, what they want and what they can expect if they choose to have surgery.
“Good team work between the right specialists – surgeons, anaesthetists and geriatricians – helps to get patients living with frailty as fit and well as possible before surgery, make the right decisions and get the best care after surgery.”
Dr Claire Shannon, President of the Royal College of Anaesthetists, said: "This research provides evidence that patients living with frailty are more likely to experience complications from surgery such as longer hospital stays and delirium. There is huge potential to improve patient outcomes by assessing all those over 60 for frailty as standard practice so that their care can be managed appropriately, with involvement from a geriatrician.
‘With older people accounting for an increasing proportion of surgical patients, implementing effective screening for frailty is becoming ever more necessary. Universal adoption of frailty assessments will not only help patients recover better from surgery but also help improve efficiency by avoiding extended lengths of stay in hospital.’

About the University of Nottingham
Ranked 97 in the world and 17th in the UK by the QS World University Rankings, the University of Nottingham is a founding member of Russell Group of research-intensive universities. Studying at the University of Nottingham is a life-changing experience, and we pride ourselves on unlocking the potential of our students. We have a pioneering spirit, expressed in the vision of our founder Sir Jesse Boot, which has seen us lead the way in establishing campuses in China and Malaysia - part of a globally connected network of education, research and industrial engagement.
Nottingham was crowned Sports University of the Year by The Times and Sunday Times Good University Guide 2024 – the third time it has been given the honour since 2018 – and by the Daily Mail University Guide 2024.
The university is among the best universities in the UK for the strength of our research, positioned seventh for research power in the UK according to REF 2021. The birthplace of discoveries such as MRI and ibuprofen, our innovations transform lives and tackle global problems such as sustainable food supplies, ending modern slavery, developing greener transport, and reducing reliance on fossil fuels.
The university is a major employer and industry partner - locally and globally - and our graduates are the third most targeted by the UK's top employers, according to The Graduate Market in 2024 report by High Fliers Research.
We lead the Universities for Nottingham initiative, in partnership with Nottingham Trent University, a pioneering collaboration between the city’s two world-class institutions to improve levels of prosperity, opportunity, sustainability, health and wellbeing for residents in the city and region we are proud to call home.
