To the Editor:
We were very encouraged to read Boddaert et al.’s review1  and Colquhoun et al.’s accompanying editorial2  on the contemporary management of elderly patients with hip fracture, an international health problem that would benefit hugely from increased U.S. clinical and observational research input. We would like to bring to readers’ attention other relevant publications about hip fracture anesthesia that were not covered by Boddaert et al.’s review.
Hip fracture is prevalent in Northern European countries, particularly in Scandinavia and the United Kingdom, which have traditionally been at the forefront of care improvement for elderly hip fracture patients. The National Hip Fracture Database in the United Kingdom has collected observational data on over a third of a million cases of hip fracture since 2007 and quotes a 30-day mortality of approximately 8%, rather than the 10% quoted by Colquhoun et al.3  One-year mortality in the United Kingdom is approximately 25%, similar to that quoted by Colquhoun et al., but lower than the “one third” quoted by Boddaert et al.
In the United Kingdom, there is an active Hip Fracture Perioperative Network4  of over 300 consultant anesthetists and orthogeriatricians who meet annually at the Age Anaesthesia Association conference to discuss future research and disseminate ideas. Although Boddaert et al. referenced the first publication from this network,5  they did not include the more recent Anaesthesia Sprint Audit of Practice,6  for which anesthetists prospectively collected data on over 11,000 hip fracture patients in 2013, and which found wide variation in national practice, suggesting that standardization of anesthetic technique may have an important role to play in future care improvements.
Over 99% of patients with hip fracture now receive surgical fixation in the United Kingdom, which enables analgesia and rehabilitation. Meta-analysis supports early fixation7 ; in Sweden, the aim is for fixation within 24 h, in England and Wales, within 36 h achieved in 72% cases.3  The Association of Anaesthetists of Great Britain and Ireland have recently produced guidance on the Management of Proximal Femoral Fractures that strongly supports preoperative orthogeriatric care as pivotal in enabling early fixation,8  particularly for frailer patients, not because it seeks to improve what is often poor but unimprovable pathophysiology, but because it ensures simple, consistent medical care—medication review, analgesia, fluid therapy, and nutrition. Expensive medical tests are seldom necessary because they do not change perioperative management. We disagree with Boddaert et al. that a large randomized control trial is required to further determine whether expedited surgery improves outcome; such a trial would likely be unethical as delay would deny some patients’ access to optimal analgesia through fracture fixation.
In turn, it is the role of the anesthetist to focus on keeping patients in status quo, using interventions that aid “re-enablement” by avoiding postoperative pain, immobility, and delirium. We disagree with Boddaert et al.’s unreferenced statement that “benzodiazepine withdrawal is the single, main easily preventable cause of postoperative delirium,” given that patients are often sleep deprived, in pain or have had general anesthesia, sedation, or opioid analgesia. Opioid-sparing, age-adjusted, brain-monitored9  general anesthesia or (preferably) sedation-free,10  low-dose spinal anesthesia11  appear to be beneficial in this regard, but further trial research is needed to confirm this. To date, for example, there has never been a randomized comparison of outcome between sedation-free spinal anesthesia and general anesthesia. Even though it remains uncertain whether nerve blocks improve outcome in hip fracture patients, they allow for opioid-sparing “dynamic” analgesia12  preoperatively13  and when positioning patients for spinal anesthesia14  and are increasingly (if not yet widely) administered in the emergency department on admission to hospital in the United Kingdom.15 
Colquhoun et al. are correct to identify the potential of the Nottingham Hip Fracture Score in stratifying outcome risk and in comparison with other scores.16  A reliable score is essential both for point prevalence and longitudinal comparisons of care within and between hospitals to identify and learn from those providing excellent care and for stratifying patient-specific risk in future clinical trials. The recently published Surgical Outcome Risk Tool needs comparison against the Nottingham Hip Fracture Score.17 
Anesthetists have an important role to play as part of the multidisciplinary care team looking after hip fracture patients, led by orthogeriatricians. Rapid improvements in care could be achieved, for example, both by close collaboration among the Age Anaesthesia Association, European Society of Anaesthesiology, Society for the Advancement of Geriatric Anaesthesia, and the American Geriatrics Association to form an international association promoting perioperative care of hip fracture patients and by the development of a U.S. National Hip Fracture Database—which would be able to collect observational data on as many hip fractures in a single year as its U.K. equivalent has in the past 7 yr.
