Frailty in the older surgical patient: a review

The rate of surgical procedures in the older population is rising. Despite surgical, anaesthetic and medical advances, older surgical patients continue to suffer from adverse postoperative outcomes. Comorbidities and reduction in physiological reserve are consistently identified as major predictors of poor postoperative outcome in this population. Frailty can be defined as a lack of physiological reserve seen across multiple organ systems and is an independent predictor of mortality, morbidity and institutionalisation after surgery. Despite this identification of frailty as a significant predictor of adverse postoperative outcome, there is not yet a consensus on the definition of frailty or how best to assess and diagnose it. This review describes our current definitions of frailty and discusses the available methods of assessing frailty, the impact on the older surgical population and the emerging potential for modification of this important syndrome.

The impact of pre-operative comprehensive geriatric assessment on postoperative outcomes in older patients undergoing scheduled surgery: a systematic review.

Comprehensive geriatric assessment is an established clinical approach. It reduces mortality and improves the physical wellbeing of older people in the community or hospitalised for medical reasons. Pre‐operative comprehensive geriatric assessment seems a plausible method for reducing adverse postoperative outcomes. The objectives of this systematic review and narrative synthesis are to describe how pre‐operative comprehensive geriatric assessment has been used in surgical patients and to examine the impact of comprehensive geriatric assessment on postoperative outcomes in older patients undergoing scheduled surgery. We searched MEDLINE, EMBASE and Web of Science from 1980 to 2013 (week 26). We included five studies: two randomised controlled trials and three before‐and‐after intervention quasi‐experimental studies. Patient populations, interventions and outcome measures varied between studies. Both the randomised trials showed benefit on postoperative outcomes, including medical complications. Two of the before‐and‐after studies reported a positive impact on postoperative length of stay and other outcomes. The heterogeneity of study methods, populations, interventions and outcomes precluded meta‐analysis. Based on this narrative synthesis, pre‐operative comprehensive geriatric assessment is likely to have a positive impact on postoperative outcomes in older patients undergoing elective surgery, but further definitive research is required. Clinical services providing pre‐operative comprehensive geriatric assessment for older surgical patients should be considered.

Peri-operative care of the elderly 2014: Association of Anaesthetists of Great Britain and Ireland.

Increasing numbers of elderly patients are undergoing an increasing variety of surgical procedures. There is an age‐related decline in physiological reserve, which may be compounded by illness, cognitive decline, frailty and polypharmacy. Compared with younger surgical patients, the elderly are at relatively higher risk of mortality and morbidity after elective and (especially) emergency surgery. Multidisciplinary care improves outcomes for elderly surgical patients. Protocol‐driven integrated pathways guide care effectively, but must be individualised to suit each patient. The AAGBI strongly supports an expanded role for senior geriatricians in coordinating peri‐operative care for the elderly, with input from senior anaesthetists (consultants/associate specialists) and surgeons. The aims of peri‐operative care are to treat elderly patients in a timely, dignified manner, and to optimise rehabilitation by avoiding postoperative complications. Effective peri‐operative care improves the likelihood of very elderly surgical patients returning to their same pre‐morbid place of residence, and maintains the continuity of their community care when in hospital. Postoperative delirium is common, but underdiagnosed, in elderly surgical patients, and delays rehabilitation. Multimodal intervention strategies are recommended for preventing postoperative delirium. Peri‐operative pain is common, but underappreciated, in elderly surgical patients, particularly if they are cognitively impaired. Anaesthetists should administer opioid‐sparing analgesia where possible, and follow published guidance on the management of pain in older people. Elderly patients should be assumed to have the mental capacity to make decisions about their treatment. Good communication is essential to this process. If they clearly lack that capacity, proxy information should be sought to determine what treatment, if any, is in the patients best interests. Anaesthetists must not ration surgical or critical care on the basis of age, but must be involved in discussions about the utility of surgery and/or resuscitation. The evidence base informing peri‐operative care for the elderly remains poor. Anaesthetists are strongly encouraged to become involved in national audit projects and outcomes research specifically involving elderly surgical patients.

The delirium experience: what is the effect on patients, relatives and staff and what can be done to modify this?

Delirium is a common clinical syndrome with significant associated mortality, morbidity and financial cost. Less is understood about the experience of delirium for the patient, their family and staff involved in their care.

Hypovitaminosis D in Older Adults

Vitamin D deficiency is increasingly recognised as a common problem among older adults. In addition to the well-known role of vitamin D in calcium homeostasis and the maintenance of bone health, recent research has started to characterise the importance of vitamin D in neuromuscular function and the way this may relate to functional performance and falls risk in older adults. In this review we describe the current state of knowledge relating to the neuromuscular effects of vitamin D and discuss treatment options.

Frailty and poor functional status are common in arterial vascular surgical patients and affect postoperative outcomes

OBJECTIVES Increasing numbers of older people are undergoing emergency and elective arterial vascular procedures. Many older patients are frail which is a recognised predictor of adverse postoperative outcomes in other surgical specialties. This study in older patients undergoing arterial vascular surgery examined; the prevalence of preoperative frailty; the clinical feasibility of preoperatively measuring frailty and functional status; the association between these characteristics and adverse postoperative outcome. METHODS Prospective observational study in patients aged over 60 years undergoing elective and emergency arterial vascular surgery. Baseline measures of frailty (Edmonton Frail Scale), functional status (gait velocity, timed up and go, hand grip strength) and cognitive function (Montreal Cognitive Assessment) were obtained preoperatively. The primary outcome measure Length of Stay (LOS) and secondary outcome measures of postoperative morbidity (medical and surgical complications), functional status and postoperative in-hospital mortality were recorded. RESULTS 125 patients were recruited. Frailty was common in this older surgical population (52% EFS score of ≥ 6.5) with high frailty scores observed (mean EFS 6.6, SD 3.05) and poor functional status (60% had TUG > 15 s, 45% had gait velocity of < 0.6 m/s). Higher preoperative EFS (> 6.5) was univariately associated with longer LOS (≥ 12 days), composite measures of postoperative infections, postoperative medical complications and adverse functional outcomes. EFS ≥ 6.5 was predictive of LOS ≥ 12 days, adjusted for age (AUC 0.660, CI 0.541-0.779, p = 0.010). This association between EFS ≥ 6.5 and LOS ≥ 12 days was strengthened with the addition of MoCA < 24 (AUC 0.695, CI 0.584-0.806, p = 0.002). CONCLUSIONS Patients aged over 60 years admitted for arterial vascular surgery were frail, had impaired functional status and were cognitively impaired. This combination of preoperative characteristics was predictive of longer hospital length of stay and associated with adverse postoperative outcome.

UK medical teaching about ageing is improving but there is still work to be done: the Second National Survey of Undergraduate Teaching in Ageing and Geriatric Medicine

Introduction: in 2008, a UK national survey of undergraduate teaching about ageing and geriatric medicine identified deficiencies, including failure to adequately teach about elder abuse, pressure ulcers and bio- and social gerontology. We repeated the survey in 2013 to consider whether the situation had improved. Method: the deans of all 31 UK medical schools were invited to nominate a respondent with an overview of their undergraduate curriculum. Nominees were invited by email and letter to complete an online questionnaire quantifying topics taught, type of teaching and assessment undertaken, and the amount of time spent on teaching. Results: one school only taught pre-clinical medicine and declined to participate. Of the 30 remaining schools, 20 responded and 19 provided analysable data. The majority of the schools (95–100%) provided teaching in delirium, dementia, stroke, falls, osteoporosis, extra-pyramidal disorders, polypharmacy, incontinence, ethics and mental capacity. Only 68% of the schools taught about elder abuse. Thirty-seven per cent taught a recognised classification of the domains of health used in Comprehensive Geriatric Assessment (CGA). The median (range) total time spent on teaching in ageing and geriatric medicine was 55.5 (26–192) h. There was less reliance on informal teaching and improved assessment:teaching ratios compared with the 2008 survey. Conclusions: there was an improvement in teaching and assessment of learning outcomes in ageing and geriatric medicine for UK undergraduates between 2008 and 2013. However, further work is needed to increase the amount of teaching time devoted to ageing and to improve teaching around elder abuse and the domains of health used in CGA.

Randomized clinical trial of comprehensive geriatric assessment and optimization in vascular surgery

Increasing numbers of older patients are undergoing vascular surgery. Inadequate preoperative assessment and optimization may contribute to increased postoperative morbidity and mortality.

Where are we in perioperative medicine for older surgical patients? A UK survey of geriatric medicine delivered services in surgery

INTRODUCTION national reports have highlighted deficiencies in care provided to older surgical patients and suggested a role for innovative, collaborative, inter-specialty models of care. The extent of geriatrician-led perioperative services in the UK (excluding orthogeriatric services) has not previously been described. This survey describes current services and explores barriers to further development. METHODS an electronic survey was sent to clinical leads for geriatric medicine at all 161 acute NHS health care trusts in the UK. Reminders were sent on three occasions over an 8-week period. The survey examined preoperative and postoperative care and organisational issues. Responses were analysed descriptively. RESULTS there were 130 respondents (80.7%). One-third (38) of respondents described providing some geriatric medicine input in older surgical patients. Preoperative services existed in 15 (12%), where 14 provided risk assessment and 13 preoperative optimisation. Twenty-six respondents (20%) delivered care postoperatively, of them 10 took a reactive approach, 11 a proactive approach and 5 provided a combination of reactive and proactive care. Barriers to establishing perioperative geriatric medicine services included funding, workforce issues and a lack of inter-specialty collaboration. CONCLUSION a national appetite exists to provide geriatrician-led services to older surgical patients yet the majority of existing services remain reactive and do not use comprehensive geriatric assessment as an organising principle. This survey suggests that funding for geriatricians in perioperative care has not yet been universally established. Future efforts should focus on dissemination of experiential knowledge and published resources, collaboration with commissioners and empirical research to overcome the barriers described.

Anaemia in the older surgical patient: a review of prevalence, causes, implications and management

This review provides the clinician with a summary of the causes, implications and potential treatments for the management of anaemia in the older surgical patient. The prevalence of anaemia increases with age and is frequently identified in older surgical patients. Anaemia is associated with increased postoperative morbidity and mortality. Allogenic blood transfusion is commonly used to treat anaemia but involves inherent risks and may worsen outcomes. Various strategies for the correction of pre- and postoperative anaemia have evolved. These include correction of nutritional deficiencies and the use of intravenous iron and erythropoesis stimulating therapy. Clear differences exist between the elective and emergency surgical populations and the translation of research findings into these individual clinical settings requires more work. This should lead to a standardized approach to the management of this frequently encountered clinical scenario.
