A Foundation Programme educational placement in peri-operative medicine for older people: mixed methods evaluation.

We established an innovative Foundation placement in peri-operative medicine for older patients in response to the need for training in 'whole patient' medicine and the challenge of fewer Foundation doctors in acute surgical roles. The placement and underpinning curriculum were co-designed with junior doctors and other clinical stakeholders. This resulted in a modular design offering acute and community experience and dedicated quality improvement project time. To evaluate the placement we used a mixed methods study based on Kirkpatrick's model of workplace learning. Level 1 (trainee reaction) was evaluated using Job Evaluation Study Tool questionnaires and nominal group technique. Levels 2 and 3 (trainee learning/behaviour) were assessed using a Likert-style survey mapped to curriculum objectives, e-portfolio completion, nominal group technique and documentation of completed quality improvement projects and oral/poster presentations. Sixty-eight foundation trainees underwent the new placement. A similar-sized 'control' sample (n = 57) of surgical Foundation trainees within the same Trust was recruited. The trainees in the peri-operative placement attained both generic Foundation and specific peri-operative curriculum competencies, and gave higher job satisfaction scores than trainees in standard surgical placements. The top three ranked advantages from the nominal group sessions were senior support, clinical variety and project opportunities. Universal project completion resulted in high rates of poster and platform presentations, and in sustained service changes at hospital level.

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

BACKGROUND: Increasing numbers of older patients are undergoing vascular surgery. Inadequate preoperative assessment and optimization may contribute to increased postoperative morbidity and mortality. METHODS: Patients aged at least 65 years scheduled for elective aortic aneurysm repair or lower-limb arterial surgery were enrolled in an RCT of standard preoperative assessment or preoperative comprehensive geriatric assessment and optimization. Randomization was stratified by sex and surgical site (aorta/lower limb). Primary outcome was length of hospital stay. Secondary outcome measures included new medical co-morbidities, postoperative medical or surgical complications, discharge to a higher level of dependency and 30-day readmission rate. RESULTS: A total of 176 patients were included in the final analysis (control 91, intervention 85). Geometric mean length of stay was 5·53 days in the control group and 3·32 days in the intervention group (ratio of geometric means 0·60, 95 per cent c.i. 0·46 to 0·79; P < 0·001). There was a lower incidence of delirium (11 versus 24 per cent; P = 0·018), cardiac complications (8 versus 27 per cent; P = 0·001) and bladder/bowel complications (33 versus 55 per cent; P = 0·003) in the intervention group compared with the control group. Patients in the intervention group were less likely to require discharge to a higher level of dependency (4 of 85 versus 12 of 91; P = 0·051). CONCLUSION: In this study of patients aged 65 years or older undergoing vascular surgery, preoperative comprehensive geriatric assessment was associated with a shorter length of hospital stay. Patients undergoing assessment and optimization had a lower incidence of complications and were less likely to be discharged to a higher level of dependency.

Specialist pre-operative assessment clinics.

While specialist pre-operative assessment is not new, its focus has evolved in response to more operations and changes in the surgical population. Patients are older and have more long-term medical comorbidities. At the same time, there has been a move from paternalistic medical decision-making to shared decision-making, based on an individual patient's choice or preference. Specialist pre-operative consultations have had to adapt to these changes by broadening their scope. Pre-operative clinics have a central role in shared decision-making, coordinating and planning care before, during and after surgery, including rehabilitation and discharge planning. Multiple specialties need to work together to deliver quality patient-centred care.

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.

The emerging specialty of perioperative medicine: a UK survey of the attitudes and behaviours of anaesthetists.

BACKGROUND: In 2014, the Royal College of Anaesthetists (RCoA) launched the Perioperative Medicine Programme to facilitate the delivery of best preoperative, intraoperative and postoperative care through implementation of evidence-based medicine to reduce variation and improve postoperative outcomes. However, variation exists in the establishment of perioperative medicine services in the UK. This survey explored attitudes and behaviours of anaesthetists towards perioperative medicine, described current anaesthetic-led perioperative medicine services across the UK and explored barriers to anaesthetic involvement in perioperative medicine. METHODS: Survey content based on the RCoA vision document was refined and validated using an expert panel. An anonymous electronic survey was then sent by email to the members of the RCoA. RESULTS: Seven hundred fifty-eight UK anaesthetists (4.5% of the RCoA mailing list) responded to the survey. Of these, 64% considered themselves a perioperative doctor, with 65% having changed local services in response to the RCoA vision. Barriers to developing perioperative medicine included insufficient time (75%) and inadequate training (51%). Three quarters of respondents advocate anaesthetists leading the development of perioperative medicine. CONCLUSIONS: Despite evidence of emerging services, this survey describes barriers to ongoing development of perioperative medicine. Facilitators may include increased clinical exposure, targeted education and training and collaborative working with other specialties.

Inhibition of weight loss by omega-3 fatty acids in an experimental cachexia model.

The effect of substitution of the carbohydrate component of the diet by calories derived from fish oil on host body weight loss and tumor growth rate has been studied in an experimental colon adenocarcinoma (MAC16). This tumor produces extensive host weight loss and reductions in both total body fat and muscle dry weight, without a reduction in food intake. Diets containing fish oil significantly reduced host body weight loss, with almost complete protection occurring when the fish oil comprised 50% of the calories, without an alteration of total calorie consumption or nitrogen intake. There was also a significant reduction in tumor growth rate, although the reduction in host weight loss was greater than might be expected from a smaller tumor burden. The reduction of host body weight loss was associated with an increase in total body fat and muscle mass. The effect appears specific to the type of fat since comparable results were not obtained with a gamma-linolenic acid-enriched diet. When compared with cyclophosphamide and 5-fluorouracil the fish oil diet exerted a similar antitumor effect at the maximum dose. Whereas the antitumor effect of the former agents was achieved with considerable host toxicity, the latter produced no toxicity and almost completely abolished the cachectic effect of the tumor. These results suggest that fish oil is a nontoxic, highly effective anticachectic agent with the added advantage of antitumor activity.

Do surgical trainees believe they are adequately trained to manage the ageing population? A UK survey of knowledge and beliefs in surgical trainees.

OBJECTIVE: Increasing numbers of older patients are undergoing surgery. Older surgical patients are at a higher risk of perioperative complications and mortality. Multimorbidity, frailty, and physiological changes of ageing contribute to adverse outcomes. These complications are predominantly medical, rather than directly surgical. Guidelines recommend preoperative assessment of comorbidity, disability, and frailty in older patients undergoing surgery and closer perioperative collaboration between surgeons and geriatricians. We conducted a survey to assess knowledge and beliefs of surgical trainees toward common perioperative problems encountered in older surgical patients. DESIGN: Paper-based survey. SETTING: Unselected UK surgical training-grade physicians (CT1-ST8) attending the 2013 Congress of The Association of Surgeons of Great Britain and Ireland, Glasgow, UK, May 1-3, 2013. PARTICIPANTS: A total of 160 eligible UK surgical trainees attending the conference were invited to participate in the survey. Of them, 157 participated. RESULTS: Of the trainees, 68% (n = 107) reported inadequate training and 89.2% (n = 140) supported the inclusion of geriatric medicine issues in surgical curricula. Of the respondents, 77.2% (n = 122) were unable to correctly identify the key features required to demonstrate mental capacity, and only 3 of 157 respondents were familiar with the diagnostic criteria for delirium. Support from geriatric medicine was deemed necessary (84.7%, n = 133) but often inadequate (68.2%, n = 107). Surgical trainees support closer collaboration with geriatric medicine and shared care of complex, older patients (93.6%, n = 147). CONCLUSIONS: UK surgical trainees believe that they receive inadequate training in the perioperative management of complex, older surgical patients and are inadequately supported by geriatric medicine physicians. In this survey sample, trainee knowledge of geriatric issues such as delirium and mental capacity was poor. Surgical trainees support the concept of closer liaison and shared care of complex, older patients with geriatric medicine physicians. Changes to surgical training and service development are needed.

Neuromuscular and psychomotor function in elderly subjects who fall and the relationship with vitamin D status.

Vitamin D and calcium supplementation significantly reduces the incidence of fractures. Evidence suggests vitamin D deficiency impairs neuromuscular function, causing an increase in falls and thereby fractures. The relationship between vitamin D, functional performance, and psychomotor function in elderly people who fall was examined in a prospective cross-sectional study. Patients were recruited from a falls clinic and stratified according to serum 25-hydroxyvitamin-D levels (25OHD): group 1, 25OHD < 12 microg/liter; group 2 25OHD, 12-17 microg/liter; and group 3, 25OHD > 17 microg/liter. Healthy elderly volunteers with 25OHD > 17 microg/liter comprised group 4 (n = 20/group). Measures included aggregate functional performance time (AFPT, seconds), isometric quadriceps strength (Newtons), postural sway (degrees), and choice reaction time (CRT, seconds). Serum bone biochemistry, 25OHD, and parathyroid hormone levels were measured. Patients who fell had significantly impaired functional performance, psychomotor function, and quadriceps strength compared with healthy subjects (AFPT: 51.0 s vs. 32.8 s,p < 0.05; CRT: 1.66 s vs. 0.98 s,p < 0.05; strength: 223N vs. 271N, t = 2.35, p = 0.02). Group 1 had significantly slower AFPT (66.0 s vs. 44.8 s, t = 4.15, p < 0.05) and CRT (2.37 s vs. 0.98 s, t = 3.59, p < 0.05) than groups 2 and 3. Group 1 had the greatest degree of postural sway and the weakest quadriceps strength, although this did not reach significance. Multivariate analysis revealed 25OHD as an independent variable for AFPT, CRT, and postural sway. PTH was an independent variable for muscle strength. Older people who fall have impaired functional performance, psychomotor function, and muscle strength. Within this group, those with 25OHD < 12 microg/liter are the most significantly affected.

The implications of a growing evidence base for drug use in elderly patients. Part 4. Vitamin D and bisphosphonates for fractures and osteoporosis.

Fractures are common in elderly subjects, disabling and occasionally fatal. Their incidence increases exponentially with age, with the commonest affected sites being the wrist, vertebrae, hip and humerus. Of these, hip fractures are the most relevant in terms of morbidity and financial cost. The increase in fracture rate with age is believed to result predominantly from age-related increases in the incidence of osteoporosis and falls. This article reviews the evidence for the use of vitamin D and bisphosphonates for the prevention of bone fractures and osteoporosis in elderly patients.

Clinical pharmacology of old age syndromes.

Several syndromes occur in old age. They are often associated with increased mortality and in all there is a paucity of basic and clinical research. The recent developments in the clinical pharmacology of three common syndromes of old age (delirium, urinary incontinence, and falls) are discussed along with directions for future research.
