Geriatric Comanagement of Older Vascular Surgery Inpatients Reduces Hospital-Acquired Geriatric Syndromes

A randomised controlled trial of a multidisciplinary TEAM-based approach to guide secondary cardiovascular risk reduction for patients with Peripheral Artery Disease (TEAM-PAD) study protocol

BACKGROUND

Peripheral arterial disease (1) is a vascular condition associated with significant cardiovascular morbidity and mortality. Effective secondary prevention strategies are essential to improve cardiovascular outcomes in patients with PAD. The TEAM-PAD study aims to determine if a centralised virtual multidisciplinary team (MDT) model of care is effective in improving guideline-recommended secondary cardiovascular risk reduction for outpatients with PAD.

METHODS

TEAM-PAD is a multicentre, randomised controlled trial involving patients with PAD. Participants will be randomised into two groups: the intervention group, who will receive care supported by cardiovascular risk reduction recommendations from a centralised MDT; and the control group, who will receive usual care by their vascular surgeon. The MDT will consist of the following clinicians: vascular surgeon, cardiologist, endocrinologist, nephrologist, geriatrician, drug health physician and clinical pharmacist. The primary outcome is the change in a composite measure of an individual's 10-year cardiovascular risk between baseline to 9-months follow-up. Secondary outcomes include control of modifiable cardiovascular risk factors and medication optimisation, cardiovascular and limb outcomes, PAD symptom control, quality of life outcomes, and health-service use outcomes.

CONCLUSION

This article details the TEAM-PAD trial protocol, which will provide robust evidence on the benefits of an MDT-based approach to cardiovascular risk reduction in PAD patients. TEAM-PAD has the potential to inform clinical practice by demonstrating whether coordinated, personalised care recommendations can improve cardiovascular risk and potentially reduce cardiovascular events in this high-risk population.

Reducing in-hospital complications in older patients undergoing plastic surgery through a collaborative model of care

BACKGROUND

There is increasing evidence to support collaborative care and proactive comprehensive geriatric assessment and management in a number of surgical specialties. Data are lacking in older people under the care of plastic surgeons. This before/after study evaluates the impact of the introduction of a shared care model between geriatric medicine and plastic surgery in an Australian metropolitan teaching hospital.

METHODS

A shared care model was implemented for all patients aged 75 years and older admitted electively and emergently under the plastic surgery team with patients admitted jointly under a plastic surgeon and geriatrician. Comprehensive geriatric assessment and management was undertaken on admission with tailored intervention along with regular inpatient review. The primary outcome of interest was rate of in-hospital complications. Secondary outcome measures included individual complications, length of stay, readmission, and discharge disposition.

RESULTS

A total of 123 consecutive patients were eligible for inclusion (63 pre-intervention, 60 intervention). The rate of complications was significantly lower in the intervention group (47.6% vs. 28.3%, P = 0.03). There was a non-significant reduction in rate of delirium and new discharge to residential aged care facility. Subgroup analysis of frailer patients (Clinical Frailty Scale ≥4) demonstrated a significant reduction in rates of delirium (44.4% vs. 15.6%, P = 0.02) and new institutionalization (18.5% vs. 0.0%, P = 0.02).

CONCLUSION

A shared care model between geriatricians and plastic surgeons has the potential to improve patient outcomes with the greatest benefit likely to be seen in older patients with frailty.

Prehabilitation for delirium prevention in elderly patients with chronic limb threatening ischemia

OBJECTIVE

Elderly patients with chronic limb-threatening ischemia (CLTI) undergoing revascularization are prone to delirium and prolonged hospitalization. Preoperative prehabilitation may prevent delirium and reduce the length of stay. This study investigates the effect of multimodal prehabilitation on delirium incidence in elderly patients with CLTI undergoing revascularization.

METHODS

A comparative observational cohort study conducted in a large teaching hospital (intervention cohort n = 101, retrospective control cohort n = 207) and a university hospital (prospective control cohort n = 48) from 2020 to 2023. Patients aged ≥65 years undergoing revascularization were included, with acute treatment or severe cognitive impairment as exclusion criteria. The 3-week prehabilitation program included screening of general health and presence of delirium risk factors by a vascular nurse practitioner, screening and provision of personalized, home-based exercises by a physiotherapist, provision of nutritional advice by a dietician, and, if indicated, comprehensive geriatric assessment by a geriatrician, assessment of self-reliance and home situation by a prearranged homecare nurse, guidance and support for smoking cessation by a quit smoking coach, and anemia treatment. Primary outcome was 30-day delirium incidence, analyzed using regression models adjusting for potential confounders (age, physical impairment, history of delirium, preoperative anemia, and revascularization type). Secondary outcomes were length of stay, postoperative complications, 30-day mortality, and patient experiences.

RESULTS

Median age was 76 years (interquartile range [IQR], 71-82 years). Delirium incidence was lower in the prehabilitation cohort (n = 2/101; 2%) compared with controls (n = 23/255; 9%; odds ratio, 0.21; 95% confidence interval, 0.05-0.89; P = .04). Adjusted analysis showed a non-significant delirium reduction (odds ratio, 0.28; 95% confidence interval, 0.06-1.3; P = .097). The prehabilitation cohort had a significantly shorter length of stay (2 [IQR, 1-5] vs 4 [IQR, 2-9] days; P ≤ .001), and fewer minor complications (14% vs 26%; P=.01). No differences were present in major complications and 30-day mortality. Patients reported high compliance and satisfaction (median score, 8/10 [IQR, 7-9]).

CONCLUSIONS

Prehabilitation among elderly patients with CLTI is safe and has the potential to yield multiple beneficial effects on general outcomes following revascularization, while also achieving high levels of patient satisfaction. Further validation and consideration of implementation in surgical settings is recommended.

Factors involved in the development of hospital-acquired conditions in older patients in acute care settings: a scoping review

BACKGROUND

Older patients hospitalized in acute care settings are at significant risk of presenting hospital-acquired conditions. Healthcare professionals should consider many factors involved in the development of such conditions, including factors related to the patients, as well as those related to the processes of care and the structure of hospitals. The aim of this study was to describe and identify the factors involved in the development of hospital-acquired conditions in older patients in acute care settings.

METHODS

A scoping review was performed based on a structured search in eight databases in September 2022. Data were extracted with an extraction tool and classified into categories. Mapping and a narrative summary were used to synthetize data.

RESULTS

A total of 237 articles were included in the scoping review. Functional decline and delirium were the most frequent hospital-acquired conditions studied. Among all categories, factors related to the patients provided most of the data, whereas factors related to the processes of care and the structure of hospitals were less frequently explored. In most articles, one or two categories of factors were retrieved; fewer articles examined factors among three categories. Personal factors, medications, and the human and work environment were the most frequent subcategories of factors retrieved, whereas social factors, hydration and nutrition, and organizational factors were less common.

CONCLUSIONS

The development of hospital-acquired conditions in older patients in acute care settings involves many factors related to the patients, as well as to the processes of care and the structure of hospitals. Prevention of hospital-acquired conditions must involve to consider the complexities of older patients and of acute care hospitals. Not considering all categories of factors might affect the implementation of new practices of care and interventions.

Development of a minimum clinical dataset for preoperative comprehensive geriatric assessment using a modified Delphi technique

OBJECTIVE

To construct a standardised, consensus-guided minimum clinical dataset (MCDS) for preoperative comprehensive geriatric assessment and optimisation (CGA) in Australia and Aotearoa New Zealand.

METHODS

We conducted a review of the international perioperative literature to identify CGA domains and tools for potential inclusion in the MCDS. We invited members of the Australian and New Zealand Society for Geriatric Medicine to participate in a Delphi study to obtain consensus on MCDS tools. Participants were asked to rate proposed tools using Likert scales (when >2 tools) or make a binary choice between two proposed tools. Consensus was considered to be achieved when there was at least 75% concordance between the two rounds amongst the participants, and at least one variable attaining over 50% of participants' votes. Domains that did not achieve consensus in Round 1 were carried over to Round 2.

RESULTS

There were 73 participants in Round 1 of the Delphi study and 47 participants in Round 2. Consensus was achieved on tool/s recommended for every MCDS domain: Clinical Frailty Scale (frailty); sMMSE, RUDAS, MoCA (cognition); 4AT (delirium); timed-up-and-go (physical function); GDS-15 (mood); Barthel Index (functional status); and MUST (malnutrition).

CONCLUSIONS

We recommend clinicians delivering preoperative CGA consider the use of the MCDS we have constructed when assessing older people contemplating surgery, as part of a multicomponent and multidisciplinary approach to optimising perioperative outcomes.

Systematic Review and Meta-analysis of the Impact of Surgeon-Physician Co-management Models on Short Term Outcomes for Vascular Surgery Inpatients

OBJECTIVE

As the population ages, vascular surgeons are treating progressively older, multimorbid patients at risk of peri-operative complications. An embedded physician has been shown to improve outcomes in general and orthopaedic surgery. This systematic review and meta-analysis aimed to investigate the impact of surgeon-physician co-management models on morbidity and mortality rates in vascular inpatients.

DATA SOURCES

PubMed, Scopus, Embase, conference abstract listings, and clinical trial registries.

REVIEW METHODS

Studies comparing adult vascular surgery inpatients under co-management with standard of care were eligible. The relative risks (RRs) of death, medical complications, and 30 day re-admission between co-management and standard care were calculated. The effect of co-management on the mean length of stay was calculated using weighted means. Risk of bias was assessed using the Methodological Index for Non-Randomised Studies, and certainty assessment with the GRADE analysis tools.

RESULTS

No randomised controlled trials were identified. Eight single institution studies between 2011 and 2020 with 7 410 patients were included. All studies were observational using before-after methodology. Studies were of high to moderate risk of bias, and outcomes were of very low GRADE certainty of evidence. Co-management was associated with a statistically significant lower relative risk of death (RR 0.64, 95% confidence interval [CI] 0.44 - 0.92; p = .02), cardiac complications (RR 0.47, 95% CI 0.25 - 0.87; p = .02), and infective complications (RR 0.49, 95% CI 0.35 - 0.67; p < .001) in vascular inpatients. No statistically significant differences in length of stay (standard mean difference -0.6 days, 95% CI -1.44 - 0.24 days; p = .16) and 30 day re-admission (RR 0.96, 95% CI 0.84 - 1.08; p = .49) were noted.

CONCLUSION

Early results of physician and surgeon co-management for vascular surgery inpatients showed promising results from very low certainty data. Further well designed, prospective studies are needed to determine how to maximise the impact of physicians within a vascular service to improve patient outcomes while using hospital resources effectively.

Comparison of Various Functional Assessment Tools to Identify Older Patients Undergoing Aortic Aneurysm Repair at Risk for Postoperative Complications

BACKGROUND

To estimate whether the benefits of aortic aneurysm repair will outweigh the risks, determining individual risks is essential. This single-center prospective cohort study aimed to compare the association of functional tools with postoperative complications in older patients undergoing aortic aneurysm repair.

METHODS

Ninety-eight patients (≥65 years) who underwent aortic aneurysm repair were included. Four functional tools were administered: the Montreal Cognitive Assessment (MoCA); the 4-Meter Walk Test (4-MWT); handgrip strength; and the Groningen Frailty Indicator (GFI). Primary outcome was the association between all tests and 30-day postoperative complications.

RESULTS

After adjusting for confounders, the odds ratio for MoCA was 1.39 (95% confidence interval [CI] 0.450; 3.157; P = 0.723), for 4-MWT 0.63 (95% CI 0.242; 1.650; P = 0.348), for GFI 1.82 (95% CI 0.783; 4.323, P = 0.162), and for weak handgrip strength 4.78 (95% CI 1.338; 17.096, P = 0.016).

CONCLUSIONS

Weak handgrip strength is significantly associated with the development of postoperative complications after aortic aneurysm repair. This study strengthens the idea that implementing a quick screening tool for risk assessment at the outpatient clinic, such as handgrip strength, identifies patients who may benefit from preoperative enhancement with help from, for example, Comprehensive Geriatric Assessment, eventually leading to better outcomes for this patient group.

How to compensate for frailty? The real life impact of geriatric co-management on morbi-mortality after colorectal cancer surgery in patients aged 70 years or older

In Europe, CRC is the second most common cause of cancer death, and surgery remains the mainstay curative treatment. Age and frailty are associated with an increased risk of postoperative morbidity and 1-year mortality. Chronological age is not sufficient to assess the risk of postoperative complications. The CGA has been developed to better identify frail patients. Geriatric co-management have been developed to optimize the post-operative outcomes. We analyzed the real-life of geriatric co-management within an ERAS program on surgical outcomes at 90 days and oncologic outcomes at 1 year in patients aged 70 years or older after surgery for CRC. This was a retrospective study based on a prospective cohort. Fifty-one patients with a G8 score ≤ 14 were referred to geriatricians for preoperative CGA (Frail Group). They were compared with 151 patients with a G8 score ≥ 15 (Robust Group). In the Frail Group, patients were significantly older with more comorbidities than the patients in the Robust Group. Oncologic characteristics, treatments and global post-operative outcomes were comparable between the two groups. One year after surgery mortality and recurrence rates were similar between the two groups. Our study suggests that geriatric co-management is feasible and contributes to the reduction of postoperative morbimortality. Moreover, performing the CGA after G8 score screening and completion of geriatric interventions resulted in similar 90-day postoperative outcomes, in frail patients than in robust patients. Our results confirmed the benefit of geriatric co-management, involving G8 screening, CGA, and ERAS, for frail older patients undergoing surgery for CRC.

New Horizons in Peripheral Artery Disease

Peripheral artery disease (PAD) is the lower limb manifestation of systemic atherosclerotic disease. PAD may initially present with symptoms of intermittent claudication, whilst chronic limb-threatening ischaemia (CLTI), the end stage of PAD, presents with rest pain and/or tissue loss. PAD is an age-related condition present in over 10% of those aged ≥65 in high-income countries. Guidelines regarding definition, diagnosis and staging of PAD and CLTI have been updated to reflect the changing patterns and presentations of disease given the increasing prevalence of diabetes. Recent research has changed guidelines on optimal medical therapy, with low-dose anticoagulant plus aspirin recommended in some patients. Recently published randomised trials highlight where bypass-first or endovascular-first approaches may be optimal in infra-inguinal disease. New techniques in endovascular surgery have increased minimally invasive options for ever more complex disease. Increasing recognition has been given to the complexity of patients with CLTI where a high prevalence of both frailty and cognitive impairment are present and a significant burden of multi-morbidity and polypharmacy. Despite advances in minimally invasive revascularisation techniques and reduction in amputation incidence, survival remains poor for many with CLTI. Shared decision-making is essential, and conservative management is often appropriate for older patients. There is emerging evidence of the benefit of specialist geriatric team input in the perioperative management of older patients undergoing surgery for CLTI. Recent UK guidelines now recommend screening for frailty, cognitive impairment and delirium in older vascular surgery patients as well as recommending all vascular surgery services have support and input from specialist geriatrics teams.

New Onset Geriatric Syndromes and One-year Outcomes Following Elective Gastrointestinal Cancer Surgery

OBJECTIVE

To assess whether older adults who develop geriatric syndromes following elective gastrointestinal surgery have poorer 1-year outcomes.

BACKGROUND

Within 10 years, 70% of all cancers will occur in older adults ≥65 years old. The rise in older adults requiring major surgery has brought attention to age-related complications termed geriatric syndromes. However, whether postoperative geriatric syndromes are associated with long-term outcomes is unclear.

METHODS

A population-based retrospective cohort study using the New York State Cancer Registry and the Statewide Planning and Research Cooperative System was performed including patients >55 years with pathologic stage I-III esophageal, gastric, pancreatic, colon, or rectal cancer who underwent elective resection between 2004 and 2018. Those aged 55 to 64 served as the reference group. The exposure of interest was a geriatric syndrome [fracture, fall, delirium, pressure ulcer, depression, malnutrition, failure to thrive, dehydration, or incontinence (urinary/fecal)] during the surgical admission. Patients with any geriatric syndrome within 1 year of surgery were excluded. Outcomes included incident geriatric syndrome, 1-year days alive and out of the hospital, and 1-year all-cause mortality.

RESULTS

In this study, 37,998 patients with a median age of 71 years without a prior geriatric syndrome were included. Of those 65 years or more, 6.4% developed a geriatric syndrome. Factors associated with an incident geriatric syndrome were age, alcohol/tobacco use, comorbidities, neoadjuvant therapy, ostomies, open surgery, and upper gastrointestinal cancers. An incident geriatric syndrome was associated with a 43% higher risk of 1-year mortality (hazard ratio, 1.43; 95% confidence interval, 1.27-1.60). For those aged 65+ discharged alive and not to hospice, a geriatric syndrome was associated with significantly fewer days alive and out of hospital (322 vs 346 days, P < 0.0001). There was an indirect relationship between the number of geriatric syndromes and 1-year mortality and days alive and out of the hospital after adjusting for surgical complications.

CONCLUSIONS

Given the increase in older adults requiring major surgical intervention, and the establishment of geriatric surgery accreditation programs, these data suggest that morbidity and mortality metrics should be adjusted to accommodate the independent relationship between geriatric syndromes and long-term outcomes.

Codesign of health technology interventions to support best-practice perioperative care and surgical waitlist management

OBJECTIVES

This project aimed to determine where health technology can support best-practice perioperative care for patients waiting for surgery.

METHODS

An exploratory codesign process used personas and journey mapping in three interprofessional workshops to identify key challenges in perioperative care across four health districts in Sydney, Australia. Through participatory methodology, the research inquiry directly involved perioperative clinicians. In three facilitated workshops, clinician and patient participants codesigned potential digital interventions to support perioperative pathways. Workshop output was coded and thematically analysed, using design principles.

RESULTS

Codesign workshops, involving 51 participants, were conducted October to November 2022. Participants designed seven patient personas, with consumer representatives confirming acceptability and diversity. Interprofessional team members and consumers mapped key clinical moments, feelings and barriers for each persona during a hypothetical perioperative journey. Six key themes were identified: 'preventative care', 'personalised care', 'integrated communication', 'shared decision-making', 'care transitions' and 'partnership'. Twenty potential solutions were proposed, with top priorities a digital dashboard and virtual care coordination.

DISCUSSION

Our findings emphasise the importance of interprofessional collaboration, patient and family engagement and supporting health technology infrastructure. Through user-based codesign, participants identified potential opportunities where health technology could improve system efficiencies and enhance care quality for patients waiting for surgical procedures. The codesign approach embedded users in the development of locally-driven, contextually oriented policies to address current perioperative service challenges, such as prolonged waiting times and care fragmentation.

CONCLUSION

Health technology innovation provides opportunities to improve perioperative care and integrate clinical information. Future research will prototype priority solutions for further implementation and evaluation.

The perceived value of a geriatrics-surgery co-management program: Perspectives from three surgical specialties

BACKGROUND

Geriatrics-surgery co-management (GSCM) programs have improved patient outcomes, but little is known about how they change care and whether their value varies by surgical specialty. We aimed to assess GSCM's effects as perceived by Orthopedic Trauma, Trauma, and Neurosurgery clinicians.

METHODS

We conducted a mixed-methods study utilizing electronic survey and virtual interviews at Penn Presbyterian Medical Center, an academic trauma center, in Philadelphia, PA. Participants included physicians, advanced practice providers, nurses, social workers, and case managers in the aforementioned specialties. Key measures were perspectives on value of GSCM, its facilitators, specialty most appropriate to manage specified medical issues, and factors affecting use.

RESULTS

Of 71 eligible clinicians, 45 (63%) completed the survey and 12 (21%) of 56 purposefully sampled for specialty-role diversity were interviewed. Clinicians across specialties valued GSCM highly and similarly for impact on personal management of older adults (grand mean [standard error, SE] = 4.33 [0.24] out of 5; p = 0.80 for specialty means comparisons), patient care (mean [SE] = 4.47 [0.21]; p = 0.27), patient outcomes (mean [SE] = 4.26 [0.22]; p = 0.51), and specialty overall (mean [SE] = 4.55 [0.23]; p = 0.25) but less so for knowledge growth (mean [SE] = 3.47 [0.29]; p = 0.11). Interviewees across specialties reported that value derived from improved understanding of patient history, management of complex medical conditions, goals of care support, communication with families, and patient discharge facilitation. Interviewees also agreed on program facilitators: aligned stakeholders, shared data-driven goals, champion/administrative support, continuity and availability of geriatricians, and thorough communication. Specialties differed on three issues: (1) who should manage some medical concerns; (2) whether GSCM makes their job easier (significantly easier for Orthopedic Trauma: mean [SE] = 4.75 [0.29] vs. Trauma: mean [SE] = 4.01 [0.19]; p = 0.05); and (3) whether GSCM increases coordination difficulty (more for Neurosurgery: mean [SE] = 2.18 [0.0.58] vs. Orthopedic Trauma: mean [SE] = 0.51 [0.42]; p = 0.03 and Trauma: mean [SE] = 0.89 [0.28]; p = 0.07). Orthopedic Trauma had the most positive impression of GSCM overall.

CONCLUSIONS

Clinicians across diverse surgical specialties valued GSCM. Hospitals considering implementation or expansion of GSCM should attend to identified facilitators and may need to tailor to specialty.

Study protocol for a national observational cohort investigating frailty, delirium and multimorbidity in older surgical patients: the third Sprint National Anaesthesia Project (SNAP 3)

INTRODUCTION

Older surgical patients are more likely to be living with frailty and multimorbidity and experience postoperative complications. The management of these conditions in the perioperative pathway is evolving. In order to support objective decision-making for patients, services and national guidance, accurate, contemporary data are needed to describe the impact and associations between frailty, multimorbidity and healthcare processes with patient and service-level outcomes.

METHODS AND ANALYSIS

The study is comprised of an observational cohort study of approximately 7500 patients; an organisational survey of perioperative services and a clinician survey of the unplanned, medical workload generated from older surgical patients. The cohort will consist of patients who are 60 years and older, undergoing a surgical procedure during a 5-day recruitment period in participating UK hospitals. Participants will be assessed for baseline frailty and multimorbidity; postoperative morbidity including delirium; and quality of life. Data linkage will provide additional details about individuals, their admission and mortality.The study's primary outcome is length of stay, other outcome measures include incidence of postoperative morbidity and delirium; readmission, mortality and quality of life. The cohort's incidence of frailty, multimorbidity and delirium will be estimated using 95% CIs. Their relationships with outcome measures will be examined using unadjusted and adjusted multilevel regression analyses. Choice of covariates in the adjusted models will be prespecified, based on directed acyclic graphs.A parallel study is planned to take place in Australia in 2022.

ETHICS AND DISSEMINATION

The study has received approval from the Scotland A Research Ethics Committee and Wales Research Ethics Committee 7.This work hopes to influence the development of services and guidelines. We will publish our findings in peer-reviewed journals and provide summary documents to our participants, sites, healthcare policy-makers and the public.

Optimising Medications in Older Vascular Surgery Patients Through Geriatric Co-management

BACKGROUND

Prescribing of potentially inappropriate medications and under-prescribing of guideline-recommended medications for cardiovascular risk modification have both been associated with negative outcomes in older adults. Hospitalisation represents an important opportunity to optimise medication use and may be achieved through geriatrician-led interventions.

OBJECTIVE

We aimed to evaluate whether implementation of a novel model of care called Geriatric Comanagement of older Vascular (GeriCO-V) surgery patients is associated with improvements in medication prescribing.

METHODS

We used a prospective pre-post study design. The intervention was a geriatric co-management model, where a geriatrician delivered comprehensive geriatric assessment-based interventions including a routine medication review. We included consecutively admitted patients to the vascular surgery unit at a tertiary academic centre aged ≥ 65 years with an expected length of stay of ≥ 2 days and who were discharged from hospital. Outcomes of interest were the prevalence of at least one potentially inappropriate medication as defined by the Beers Criteria at admission and discharge, and rates of cessation of at least one potentially inappropriate medication present on admission. In the subgroup of patients with peripheral arterial disease, the prevalence of guideline-recommended medications on discharge was determined.

RESULTS

There were 137 patients in the pre-intervention group (median [interquartile range] age: 80.0 [74.0-85.0] years, 83 [60.6%] with peripheral arterial disease) and 132 patients in the post-intervention group (median [interquartile range] age: 79.0 (73.0-84.0) years, 75 [56.8%] with peripheral arterial disease). There was no change in the prevalence of potentially inappropriate medication use from admission to discharge in either group (pre-intervention: 74.5% on admission vs 75.2% on discharge; post-intervention: 72.0% vs 72.7%, p = 0.65). Forty-five percent of pre-intervention group patients had at least one potentially inappropriate medication present on admission ceased, compared with 36% of post-intervention group patients (p = 0.11). A higher number of patients with peripheral arterial disease in the post-intervention group were discharged on antiplatelet agent therapy (63 [84.0%] vs 53 [63.9%], p = 0.004) and lipid-lowering therapy (58 [77.3%] vs 55 [66.3%], p = 0.12).

CONCLUSIONS

Geriatric co-management was associated with an improvement in guideline-recommended antiplatelet agent prescribing aimed at cardiovascular risk modification for older vascular surgery patients. The prevalence of potentially inappropriate medications was high in this population, and was not reduced with geriatric co-management.

Frailty: understanding the difference between age and ageing

In the past, illness and dependence were viewed as inevitable consequences of old age. Now, we understand that there is a difference between age (the passing of chronological time) and ageing (the increased risk of adverse outcomes over time). Over the last 50 years, 'frailty' research has established that ageing is heterogeneous, variable and malleable. Significant advances have been made in frailty measurement (description of clinical features and development of clinical models), mechanisms (insights into pathogenesis) and management (development of interventions to reduce and/or prevent progression). Subsequently, the concept of frailty has informed health policy and clinical practice and started to change perceptions of older age held by the general public and the health sector. Here, we overview key achievements in frailty research and clinical practice and highlight the considerable number of known unknowns that may be addressed in the future.

Perioperative care for older people

Increasing numbers of older people are undergoing surgery with benefits including symptom relief and extended longevity. Despite these benefits, older people are more likely than younger patients to experience postoperative complications, which are predominantly medical as opposed to surgical. Comprehensive Geriatric Assessment and optimisation offers a systematic approach to risk assessment and risk modification in the perioperative period. Clinical evidence shows that Comprehensive Geriatric Assessment and optimisation reduces postoperative medical complications and is cost effective in the perioperative setting. These benefits have been observed in patients undergoing elective and emergency surgery. Challenges in the implementation of perioperative Comprehensive Geriatric Assessment and optimisation services are acknowledged. These include the necessary involvement of a wide stakeholder group, limited available geriatric medicine workforce and ensuring fidelity to Comprehensive Geriatric Assessment methodology with adaptation to the local context. Addressing these challenges needs a cross-specialty, interdisciplinary approach underpinned by evidence-based medicine and implementation science with upskilling to facilitate innovative use of the extended workforce. Future delivery of quality patient-centred perioperative care requires proactive engagement with national audit, collaborative guidelines and establishment of networks to share best practice.

Geriatric Cardiology: Coming of Age

Older adults with cardiovascular disease (CVD) contend with deficits across multiple domains of health due to age-related physiological changes and the impact of CVD. Multimorbidity, polypharmacy, cognitive changes, and diminished functional capacity, along with changes in the social environment, result in complexity that makes provision of CVD care to older adults challenging. In this review, we first describe the history of geriatric cardiology, an orientation that acknowledges the unique needs of older adults with CVD. Then, we introduce 5 essential principles for meeting the needs of older adults with CVD: 1) recognize and consider the potential impact of multicomplexity; 2) evaluate and integrate constructs of cognition into decision-making; 3) evaluate and integrate physical function into decision-making; 4) incorporate social environmental factors into management decisions; and 5) elicit patient priorities and health goals and align with care plan. Finally, we review future steps to maximize care provision to this growing population.

Multicomponent Prehabilitation as a Novel Strategy for Preventing Delirium in Older Chronic Limb Threatening Ischemia Patients: A Study Protocol

Objective

Chronic limb threatening ischemia is the final stage of peripheral arterial disease. Current treatment is based on revascularization to preserve the leg. In the older, hospitalized chronic limb threatening ischemia patient, delirium is a frequent and severe complication after revascularization. Delirium leads to an increased length of hospital stay, a higher mortality rate and a decrease in quality of life. Currently, no specific guidelines to prevent delirium in chronic limb threatening ischemia patients exist. We aim to evaluate the effect of a multicomponent, multidisciplinary prehabilitation program on the incidence of delirium in chronic limb threatening ischemia patients ≥65 years.

Design

A prospective observational cohort study to investigate the effects of the program on the incidence of delirium will be performed in a large teaching hospital in the Netherlands. This manuscript describes the design of the study and the content of this specific prehabilitation program.

Methods

Chronic limb threatening ischemia patients ≥65 years that require revascularization will participate in the program. This program focuses on optimizing the patient's overall health and includes delirium risk assessment, nutritional optimization, home-based physical therapy, iron infusion in case of anaemia and a comprehensive geriatric assessment in case of frailty. The primary outcome is the incidence of delirium. Secondary outcomes include quality of life, amputation-free survival, length of hospital stay and mortality. Exclusion criteria are the requirement of acute treatment or patients who are mentally incompetent to understand the procedures of the study or to complete questionnaires. A historical cohort from the same hospital is used as a control group.

Discussion

This study will clarify the effect of a prehabilitation program on delirium incidence in chronic limb threatening ischemia patients. New insights will be obtained on optimizing a patient's preoperative mental and physical condition to prevent postoperative complications, including delirium.

Trial

This protocol is registered at the Netherlands National Trial Register (NTR) number: NL9380.
