The Emerging Role and Clinical Applications of Morphomics in Diagnostic Imaging

Analytic morphomics refers to the accurate measurement of specific biological markers of human body composition in diagnostic medical imaging. The increasing prevalence of disease processes that alter body composition including obesity, cachexia, and sarcopenia has generated interest in specific targeted measurement of these metrics to possibly prevent or reduce negative health outcomes. Typical morphomic measurements include the area and density of muscle, bone, vascular calcification, visceral fat, and subcutaneous fat on a specific validated axial level in the patient's cross-sectional diagnostic imaging. A distinct advantage of these measurements is that they can be made retrospectively and opportunistically with pre-existing datasets. We provide a narrative review of the current state of art in morphomics, but also consider some potential future directions for this exciting field. Imaging based quantitative assessment of body composition has enormous potential across the breadth and scope of modern clinical practice. From risk stratification to treatment planning, and outcome assessment, all can be enhanced with the use of analytic morphomics. Moreover, it is likely that many new opportunities for personalized medicine will emerge as the field evolves. As radiologists, embracing analytic morphomics will enable us to contribute added value in the care of every patient.

Comprehensive geriatric assessment, and related interventions, to improve outcomes for older patients undergoing transcatheter aortic valve implantation (TAVI): a systematic review

INTRODUCTION

Transcatheter aortic valve implantation (TAVI) is a treatment for people with severe symptomatic aortic stenosis, particularly those living with frailty. Increasing frailty is associated with poorer outcomes post-TAVI. Comprehensive Geriatric Assessment (CGA) has been shown in other settings to improve outcomes in those with frailty, including perioperatively. This systematic review aims to determine whether CGA, or interventions targeting its components, improves outcomes for older people undergoing TAVI.

METHODS

EMBASE, MEDLINE, CINAHL and Cochrane CENTRAL were searched on 09/01/23 and then the search was rerun on the 16/04/24. The review was registered on PROSPERO (CRD42022299955). Included studies had to evaluate either CGA, or a single- or multi-domain intervention targeting components of CGA, in those aged ≥ 65.

RESULTS

From 4091 papers, 24 met the inclusion criteria. Two studies assessed CGA pre-TAVI and reported mixed improvements in functional independence but no change in length of stay or post-operative delirium, although both studies had a serious risk of bias. Fifteen papers described an exercise-based intervention, and 1 paper detailed a Cognitive Behavioural Therapy-based intervention. Seven studies evaluated a multi-component intervention. There were conflicting results reported for the multi-component and single-component interventions. All studies had at least a moderate risk of bias.

CONCLUSION(S)

There is a lack of evidence to determine whether CGA, or related interventions, improve outcomes for older adults undergoing-TAVI. The evidence for perioperative CGA, and the results of this review, support the need for well-designed trials evaluating whether CGA improves outcomes post-TAVI for older adults living with frailty.

Vestibular schwannoma surgery in the ninth decade of life: a case series

BACKGROUND AND PURPOSE

Large symptomatic Vestibular Schwannoma (VS) often requires surgical resection, regardless the patient's age. The aim of this study was to assess the surgical outcomes of patients in their ninth decade of life.

METHODS

This monocenter retrospective observational study included patients aged 80 years or older who underwent VS surgery between 2009 and 2020. We retrospectively analyzed their immediate post-surgical and long-term outcomes and complications.

RESULTS

Thirteen octogenarians who underwent VS surgery were included, with average age of 83.2 ± 1.97 years old (median 83.5, range 80-86 years). One patient had a Koos-Grade II tumor, and 12 patients had a grade IV. All patients had a preoperative ASA score ≤ 3 and underwent surgery in the supine position. Twelve patients underwent a pre-planned partial resection (PR) and one had a gross-total resection (GTR). Good facial function (House-Brackmann grade ≤ 2) was achieved in 10 patients (77%). We reported three Clavien-Dindo grade ≤ 3 treatment-related complications and no life-threatening complication. Two patients experienced tumor recurrence after PR.

CONCLUSION

In this series of patients who underwent VS surgery in their ninth decade of life, surgical outcomes were acceptable. Therefore, age alone should not serve as a contraindication for surgery. Preplanned PR is a reasonable attitude in elderly patients.

Using Systems Engineering and Implementation Science to Design an Implementation Package for Preoperative Comprehensive Geriatric Assessment Among Older Adults Having Major Abdominal Surgery: Protocol for a 3-Phase Study

BACKGROUND

Older Americans, a growing segment of the population, have an increasing need for surgical services, and they experience a disproportionate burden of postoperative complications compared to their younger counterparts. A preoperative comprehensive geriatric assessment (pCGA) is recommended to reduce risk and improve surgical care delivery for this population, which has been identified as vulnerable. The pCGA optimizes multiple chronic conditions and factors commonly overlooked in routine preoperative planning, including physical function, polypharmacy, nutrition, cognition, mental health, and social and environmental support. The pCGA has been shown to decrease postoperative morbidity, mortality, and length of stay in a variety of surgical specialties. Although national guidelines recommend the use of the pCGA, a paucity of strategic guidance for implementation limits its uptake to a few academic medical centers. By applying implementation science and human factors engineering methods, this study will provide the necessary evidence to optimize the implementation of the pCGA in a variety of health care settings.

OBJECTIVE

The purpose of this paper is to describe the study protocol to design an adaptable, user-centered pCGA implementation package for use among older adults before major abdominal surgery.

METHODS

This protocol uses systems engineering methods to develop, tailor, and pilot-test a user-centered pCGA implementation package, which can be adapted to community-based hospitals in preparation for a multisite implementation trial. The protocol is based upon the National Institutes of Health Stage Model for Behavioral Intervention Development and aligns with the goal to develop behavioral interventions with an eye to real-world implementation. In phase 1, we will use observation and interviews to map the pCGA process and identify system-based barriers and facilitators to its use among older adults undergoing major abdominal surgery. In phase 2, we will apply user-centered design methods, engaging health care providers, patients, and caregivers to co-design a pCGA implementation package. This package will be applicable to a diverse population of older patients undergoing major abdominal surgery at a large academic hospital and an affiliate community site. In phase 3, we will pilot-test and refine the pCGA implementation package in preparation for a future randomized controlled implementation-effectiveness trial. We anticipate that this study will take approximately 60 months (April 2023-March 2028).

RESULTS

This study protocol will generate (1) a detailed process map of the pCGA; (2) an adaptable, user-centered pCGA implementation package ready for feasibility testing in a pilot trial; and (3) preliminary pilot data on the implementation and effectiveness of the package. We anticipate that these data will serve as the basis for future multisite hybrid implementation-effectiveness clinical trials of the pCGA in older adults undergoing major abdominal surgery.

CONCLUSIONS

The expected results of this study will contribute to improving perioperative care processes for older adults before major abdominal surgery.

Perioperative geriatrics: A bibliometric analysis of the top 100 cited articles in an emerging specialty

BACKGROUND

The success of modern medicine has led to surgery being performed on an increasingly older, frailer and more comorbid population. As a result, perioperative geriatrics has emerged as an important specialty, relevant to both medical and surgical disciplines. Only a small number of papers have been published on the topic. A bibliometric analysis is used to identify themes and trends in current research and practice.

OBJECTIVES

To identify and describe research topics relating to perioperative geriatrics; to find themes and gaps in the current literature.

METHODS

Thompson Reuters Web of Science indexing database was searched for all manuscripts relating to perioperative geriatrics. Of these, the top 100 were subcategorised into manuscript type, age, theme, specialty, journal and citation rate.

RESULTS

The highest cited article was by Bhandari et al with 294 citations. The highest citation rate was achieved by Partridge et al, with 23.75 citations/year. Across the series, the mean number of citations was 50.41 (range 294-12). The highest number of manuscripts were published between 2010 and 2019 (n = 55), with 70% of manuscripts published in journals with impact factor <5. The specialty with the highest number of publications was orthopaedics (n = 36). Most articles focussed on surgical management of geriatrics patients, followed by anaesthetic management.

CONCLUSION

This is the first bibliometric analysis of the top 100 most cited papers in perioperative geriatrics. Only 395 papers were returned, indicating that this needs to be further researched as a topic. Key themes identified were surgical management of hip fractures and anaesthetic preoperative assessment. Emerging themes from this study highlight the need for perioperative publications in the fields of geriatric vascular, general, plastic and gynaecology.

Impact of comprehensive geriatric assessment on treatment strategies and complications in older adults with colorectal cancer considering surgery

BACKGROUND AND OBJECTIVES

This study aimed to assess the effectiveness of Comprehensive Geriatric Assessment (CGA) in customizing care for elderly cancer patients, specifically focusing on colorectal cancer. The research compared treatment strategies and outcomes in older adults considered for surgery before and after the initiation of a Geriatric Oncology Service (GOS).

METHODS

Conducting a comparative study, two cohorts of consecutive colorectal cancer patients aged 75 or older were examined: the control group (n = 156) and the GOS group (n = 158). Upon the treating surgeon's GOS consultation request, a geriatrician and an oncologist performed CGA, guiding treatment decisions and perioperative interventions. Postoperative complications were compared using propensity score matching (PSM).

RESULTS

In the GOS group, 91% (n = 116) underwent CGA consultations, influencing decisions to forego surgery in 12 patients. After PSM for surgical cases (controls n = 146, GOS n = 146), each group comprised 128 patients. Perioperative physical therapy and pharmacist referrals were more frequent in the GOS group. The GOS group exhibited a significantly lower incidence of postoperative complications (22%) compared to the control group (33%) (p = 0.0496).

CONCLUSION

Patients undergoing colorectal surgery post-GOS implementation experienced a notable reduction in postoperative complications, highlighting the positive impact of personalized geriatric assessment on surgical outcomes in the elderly.

Loss of Independence in Older Adults With Operable Oral Cavity Cancer: A Retrospective Cohort Study

OBJECTIVE

To ascertain the effect of curative-intent surgery on loss of independence (LOI) in patients with oral cavity squamous cell carcinoma (OCSCC).

STUDY DESIGN

Retrospective observational study of patients diagnosed from 2014 to 2021.

SETTING

Single tertiary care academic center. Patients having undergone curative-intent surgical treatment for OCSCC from 2014 to 2021 in the cancer registry.

METHODS

LOI as the primary outcome was measured based on a combination of decrease in activities of daily living (ADLs) and/or decline in mobility during treatment. Descriptive statistics were used to compare baseline demographics and multivariable logistic regression was used to assess the association between LOI and perioperative variables of interest.

RESULTS

Of the 180 patients included in this study, 139 (79%) were fully independent in ADLs/instrumental ADLs prior to surgery. The average age of the cohort was 74 with 49% males. Thirty-seven (21%) experienced a decline in mobility or increased care needs following surgery, and 18 (10%) experienced an independent decline in functional status. Increasing age, osseous flap reconstruction, high Charlson Comorbidity Index, and major postoperative adverse events were associated with LOI. Fifty-five percent of patients with LOI had recovered to baseline within 7 months from surgery. LOI was associated with poor treatment tolerance (odds ratio: 4.77, 95% confidence interval: 1.87-12.2) while adjusting for multiple confounders.

CONCLUSION

LOI is common in older adults undergoing curative-intent surgery for OCSCC and associated with poor treatment tolerance.

The significance of G8 and other geriatric assessments in urologic cancer management: A comprehensive review

In urologic oncology, which often involves older patients, it is important to consider how to manage their care appropriately. Geriatric assessment (GA) is a method that can address the specific needs of older cancer patients. The GA encompasses various assessment domains, but these domains exhibit variations across the literature. Some of the common items include functional ability, nutrition, comorbidities, cognitive ability, psychosocial disorders, polypharmacy, social and financial support, falls/imbalance, and vision/hearing. Despite the diversity of domains, there is limited consensus on reliable measurement methods. This review discusses the role of GA in managing urologic cancer in unique scenarios, such as those necessitating temporary or permanent urinary catheters or stomas due to urinary diversion. A comprehensive GA is time and human-resource-intensive in real-world clinical practice. Hence, simpler tools such as the Geriatric-8 (G8), capable of identifying high-risk patients requiring a detailed GA, are also under investigation in various contexts. Therefore, we conducted a systematic literature review on the G8. Our findings indicate that patients with low G8 scores encounter difficulties with stoma self-care after urinary diversion and have higher risks of urinary tract infections and ileus after radical cystectomy. The utilization of G8 as a screening tool for urologic cancer patients may facilitate the delivery of appropriate and personalized treatment and care.

Value of a multidisciplinary geriatric oncology committee on patient care in a community-based, academic cancer center

INTRODUCTION

The heterogeneity in health and functional ability among older patients makes the management of cancer a unique challenge. The Geriatric Oncology Program at the University of Maryland Baltimore Washington Medical Center (BWMC) was created to optimize cancer management for older patients. This study aimed to assess the benefits of the implementation of such a program at a community-based academic cancer center.

MATERIALS AND METHODS

We analyzed patients aged ≥80 years presenting to the Geriatric Oncology Program between 2017 and 2022. A multidisciplinary team of specialists collectively reviewed each patient using geriatric-specific domains and stratified each patient into one of three management groups- Group 1: those deemed fit to receive standard oncologic care (SOC); Group 2: those recommended to receive optimization services prior to reassessment for SOC; and Group 3: those deemed to be best suited for supportive care and/or hospice care.

RESULTS

The study cohort consisted of 233 patients, of which 76 (32.6%) received SOC, 43 (18.5%) were optimized, and 114 (49.0%) received supportive care or hospice referral. Among the optimized patients, 69.8% were deemed fit for SOC upon re-evaluation following their respective optimization services. The Canadian Study of Health and Aging-Clinical Frailty Scale (CSHA-CFS) score was implemented in 2019 (n = 90). Patients receiving supportive/hospice care only had an average score of 5.8, while the averages for those in the optimization and SOC groups were 4.6 and 4.1, respectively (p ≤0.001). Patients receiving SOC had the longest average survival of 2.71 years compared to the optimization (2.30 years) and supportive care groups (0.93 years) (p ≤0.001). For all patients that underwent surgical interventions post-operatively, 23 patients (85%) were discharged home and four (15%) were discharged to a rehabilitation facility.

DISCUSSION

The present study demonstrates the profound impact that the complexities in health status and frailty among older individuals can have during cancer management. The Geriatric Oncology Program at BWMC maximized treatment outcomes for older adults through the provision of SOC therapies and optimization services, while also minimizing unnecessary interventions on an individual patient-centric level.

Perioperative outcome, long-term mortality and time trends in elderly patients undergoing low-, intermediate- or major non-cardiac surgery

BACKGROUND

Decision-making whether older patients benefit from surgery can be a difficult task. This report investigates characteristics and outcomes of a large cohort of inpatients, aged 80 years and over, undergoing non-cardiac surgery.

METHODS

This observational study was performed at a tertiary university medical centre in the Netherlands. Patients of 80 years or older undergoing elective or urgent surgery from January 2004 to June 2017 were included. Outcomes were length of stay, discharge destination, 30-day and long-term mortality. Patients were divided into low-, intermediate and high-risk surgery subgroups. Univariable and multivariable logistic regression were used to evaluate the association of risk factors and outcomes. Secondary outcomes were time trends, assessed with Mantel-Haenszel chi-square test.

RESULTS

Data of 8251 patients, undergoing 19,027 surgical interventions were collected from the patients' medical record. 7032 primary procedures were suitable for analyses. Median LOS was 3 days in the low-risk group, compared to six in the intermediate- and ten in the high-risk group. Median LOS of the total cohort decreased from 5.8 days (IQR 1.9-14.5) in 2004-2007 to 4.6 days (IQR 1.9-9.0) in 2016-2017. Three quarters of patients were discharged to their home. Postoperative 30-day mortality in the low-risk group was 2.3%. In the overall population 30-day mortality was high and constant during the study period (6.7%, ranging from 4.2 to 8.4%).

CONCLUSION

Patients should not be withheld surgery solely based on their age. However, even for low-risk surgery, the mortality rate of more than 2% is substantial. Deciding whether older patients benefit from surgery should be based on the understanding of individual risks, patients' wishes and a patient-centred plan.

Association of risk analysis index with 90-day failure to rescue following major abdominal surgery in geriatric patients

BACKGROUND

Failure to rescue (FTR) is a quality metric defined as mortality after potentially preventable complications after surgery. Predicting patients who are at the highest risk of mortality after a complication may aid in preventing deaths. Thirty-day follow-up period inadequately captures postoperative deaths; alternatively, a 90-day follow-up period has been advocated. This study aimed to examine the association of a validated frailty metric, the risk analysis index (RAI), with 90-day FTR (FTR-90).

METHODS

Patients aged ≥65 years who underwent a major abdominal operation between 2014 and 2020 at a quaternary care center were abstracted. Institutional data were merged with the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) and Geriatric Surgery Research File variables. The association between RAI and FTR-90 was evaluated using multivariable logistic regression.

RESULTS

A total of 398 patients with postoperative complications were included. Fifty-two patients (13.1%) died during the 90-day follow-up. The FTR-90 group was older (median age: 76 vs 73 years, respectively; P = .002), had a greater preoperative American Society of Anesthesiologists classification score (P < .001), and had a higher ACS NSQIP estimated risk of morbidity (0.33% vs 0.20%, P < .001) and mortality (0.067% vs 0.012%, P < .001). The FTR-90 group had a greater median RAI score (23 vs 19; P = .002). The RAI score was independently associated with FTR-90 (odds ratio, 1.04; 95% CI, 1.0042-1.0770; P = .028) but not with FTR-30 (P = .13).

CONCLUSION

Preoperative frailty, as defined by RAI, is independently associated with FTR at 90-day follow-up. FTR-90 captured nearly 60% more deaths than did FTR-30. Frailty has major implications beyond the typical 30-day follow-up period, and a longer follow-up period must be considered.

[SOG-Special Orthopedic Geriatrics : First interim results of a randomized controlled study on integrated orthogeriatric care in elective hip and knee arthroplasty]

BACKGROUND

To date, there are no adequate care concepts for geriatric patients undergoing elective orthopaedic surgery in Germany. The Special Orthopaedic Geriatrics (SOG) study evaluates for the first time in Germany the impact of comprehensive orthogeriatric co-management on the outcome of elderly patients with elective hip and knee replacements compared to standard orthopaedic care.

METHODS

The interim analysis of the ongoing study included 174 patients; 87 patients were randomized to the intervention group and 87 to the control group. The SOG care model consists of screening, preoperative assessment with preoperative intervention, fast-track surgery and multimodal perioperative care in the orthogeriatric team. The control group received standard orthopaedic care. Mobility, complications, and patient-reported outcome measures after surgery were compared.

RESULTS

The SOG group showed a clinically relevant improvement in mobility postoperatively compared to the control group at all time points (p < 0.01). The evaluation of complications showed a significant risk reduction for minor complications (p < 0.01), as well as a clear trend towards a risk reduction for major complications. Patient-reported outcome measures showed a significant improvement in joint function and general health-related quality of life both in the SOG group and the control group.

CONCLUSION

Integrated orthogeriatric care models such as SOG could improve the care of geriatric patients in elective orthopaedic surgery in the future and, above all, make it safer.

Inappropriate polypharmacy management versus deprescribing: A review on their relationship

Medication burden and polypharmacy are highly prevalent among patients with multimorbidity. There have been multiple initiatives to overcome polypharmacy and medication burden in patients with multimorbidity. These initiatives have evolved over time as effective in reducing the negative health consequences of polypharmacy. In recent years, the concept and practice of deprescribing has emerged and gained popularity as an efficient comprehensive approach to manage polypharmacy and ultimately improve health outcomes. Clinicians and researchers with interest in deprescribing view it as a novel and unique strategy that should be a part of effective prescribing process. However, other traditional polypharmacy management strategies such as drug review and medication therapy management still coexist. It is intriguing if deprescribing is considered as a type of these strategies or not. This narrative mini-review explored published literature in an effort to ascertain the differences and similarities between deprescribing and other prominent polypharmacy management interventions. It is clear that there is an overlap between deprescribing and inappropriate polypharmacy management. This is represented by focusing on multimorbid older adults, using similar explicit and implicit tools and having drug review as the core principle of both approaches. This overlap has probably made deprescribing considered as one of polypharmacy management approaches.

Knee Extensor Weakness Potently Predicts Postoperative Outcomes in Older Gastrointestinal Cancer Patients

OBJECTIVES

Muscle weakness, assessed by grip strength, has been shown to predict postoperative mortality in older patients with cancer. Because lower extremity muscle strength well reflects physical performance, we examined whether lower knee extension muscle strength predicts postoperative mortality better than grip strength in older patients with gastrointestinal cancer.

DESIGN

Prospective, observational study in a single institution.

SETTING AND PARTICIPANTS

A total of 813 patients (79.0 ± 4.2 years, 66.5% male) aged 65 years or older with gastrointestinal cancer who underwent preoperative evaluation of grip strength and isometric knee extension muscle strength between April 2012 and April 2019 were included.

METHODS

The study participants were prospectively followed up for postoperative mortality. Muscle weakness was defined as the lowest quartile of grip strength or knee extension strength (GS-muscle weakness and KS-muscle weakness, respectively).

RESULTS

Among the study participants, 176 patients died during a median follow-up of 716 days. In the Kaplan-Meier analysis, we found that patients with both GS-muscle weakness and KS-muscle weakness had a lower survival rate than those without muscle weakness. As expected, higher clinical stages and abdominal and thoracic surgeries compared with endoscopic surgery were associated with increased all-cause mortality. In addition, we found that KS-muscle weakness, but not GS-muscle weakness, was an independent prognostic factor after adjusting for sex, body mass index, cancer stage, surgical technique, and surgical site in the Cox proportional hazard model.

CONCLUSIONS AND IMPLICATIONS

In older patients with gastrointestinal cancer, muscle weakness based on knee extension muscle strength can be a better predictor of postoperative prognosis than muscle weakness based on grip strength.

Effectiveness of geriatric assessment and management in older cancer patients: a systematic review and meta-analysis

BACKGROUND

Frailty and multimorbidity among older cancer patients affect treatment tolerance and efficacy. Comprehensive geriatric assessment and management is recommended to optimize cancer treatment, but its effect on various outcomes remains uncertain.

OBJECTIVE

Our objective was to conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) and cost-effectiveness studies comparing comprehensive geriatric assessment (with or without implementation of recommendations) to usual care in older cancer patients.

METHODS

We searched MEDLINE, EMBASE, CINAHL, and Cochrane trials from inception to January 27, 2023, for RCTs and cost-effectiveness studies. Pooled estimates for outcomes were calculated using random-effects models.

RESULTS

A total of 19 full-text articles representing 17 RCTs were included. Average participant age was 72-80 years, and 31%-62% were female. Comprehensive geriatric assessment type, mode of delivery, and evaluated outcomes varied across studies. Meta-analysis revealed no difference in risk of mortality (risk ratio [RR] = 1.08. 95% confidence interval [CI] = 0.91 to 1.29), hospitalization (RR = 0.92, 95% CI = 0.77 to 1.10), early treatment discontinuation (RR = 0.89, 95% CI = 0.67 to 1.19), initial dose reduction (RR = 0.99, 95% CI = 0.99 to 1.26), and subsequent dose reduction (RR = 0.87, 95% CI = 0.70 to 1.09). However, the risk of treatment toxicity was statistically significantly lower in the comprehensive geriatric assessment group (RR = 0.78, 95% CI = 0.70 to 0.86). No cost-effectiveness studies were identified.

CONCLUSION

Compared with usual care, comprehensive geriatric assessment was not associated with a difference in risk of mortality, hospitalization, treatment discontinuation, and dose reduction but was associated with a lower risk of treatment toxicity indicating its potential to optimize cancer treatment in this population. Further research is needed to evaluate cost-effectiveness.

Perioperative mortality among geriatric patients in Ethiopia: a prospective cohort study

Background

With the dramatic growth in the aged population observed in developed and developing nations, the older population burdened by unmet demand for surgical treatment has become a significant yet unnoticed public health concern in resource-limited countries. Studies are limited regarding surgical mortality of geriatric patients in Africa. Therefore, this study aims to estimate the incidence and identify predictors of postoperative mortality using prospective data in a low-income country, Ethiopia.

Methods and materials

A prospective cohort study was conducted from June 01, 2019, to June 30, 2021, at a tertiary-level hospital in Ethiopia. Perioperative data were collected using an electronic data collection tool. Cox regression analysis was used to identify predictor variables. The association between predictors and postoperative mortality among geriatrics was computed using a hazard ratio (HR) with a 95% confidence interval (CI); p-value <0.05 was a cutoff value to declare statistical significance.

Results

Of eligible 618 patients, 601 were included in the final analysis. The overall incidence of postoperative mortality among geriatrics was 5.16%, with a rate of 1.91 (95% CI: 1.34, 2.72) deaths per 1,000 person-day observation. Age ≥ 80 years (Adjusted hazard ratio (AHR) = 2.59, 95% CI: 1.05, 6.36), ASA physical status III/IV (AHR = 2.40, 95%CI 1.06, 5.43), comorbidity (AHR = 2.53, 95% CI: 1.19, 7.01), and emergency surgery (AHR = 2.92, 95% CI: 1.17, 7.27) were the significant predictors of postoperative mortality among older patients.

Conclusion

Postoperative mortality among geriatrics was high. Identified predictors were age ≥ 80 years, ASA status III/IV, comorbidity, and emergency surgery. Target-specific interventions should be addressed to improve high surgical mortality in these patients.

Incidence of preoperative instrumental activities of daily living (IADL) dependence and adverse outcomes in older surgical patients: A systematic review and meta-analysis

STUDY OBJECTIVE

Instrumental activities of daily living (IADLs) are essential to patient function and quality of life after surgery. In older surgical patients, the incidence of preoperative IADL dependence has not been well characterized in the literature. This systematic review and meta-analysis aimed to determine the pooled incidence of preoperative IADL dependence and the associated adverse outcomes in the older surgical population.

DESIGN

Systematic review and meta-analysis.

SETTING

MEDLINE, MEDLINE Epub Ahead of Print and In-Process, In-Data-Review & Other Non-Indexed Citations, Embase/Embase Classic, Cochrane CENTRAL, and Cochrane Database of Systematic Reviews, ClinicalTrials.Gov, the WHO ICTRP (International Clinical Trials Registry Platform) were searched for relevant articles from 1969 to April 2022.

PATIENTS

Patients aged ≥60 years old undergoing surgery with preoperative IADL assessed by the Lawton IADL Scale.

INTERVENTIONS

Preoperative assessment.

MEASUREMENT

The primary outcome was the pooled incidence of preoperative IADL dependency. Additional outcomes included post-operative mortality, postoperative delirium [POD], functional status improvement, and discharge disposition.

MAIN RESULTS

Twenty-one studies (n = 5690) were included. In non-cardiac surgeries, the pooled incidence of preoperative IADL dependence was 37% (95% CI: 26.0%, 48.0%) among 2909 patients. Within cardiac surgeries, the pooled incidence of preoperative IADL dependence was 53% (95% CI: 24.0%, 82.0%) among 1074 patients. Preoperative IADL dependence was associated with an increased risk of postoperative delirium than those without IADL dependence (44.9% vs 24.4, OR 2.26; 95% CI: 1.42, 3.59; I2: 0%; P = 0.0005).

CONCLUSIONS

There is a high incidence of IADL dependence in older surgical patients undergoing non-cardiac and cardiac surgery. Preoperative IADL dependence was associated with a two-fold risk of postoperative delirium. Further work is needed to determine the feasibility of using the IADL scale preoperatively as a predictive tool for postoperative adverse outcomes.

A systematic review of predictive accuracy via c-statistic of preoperative frailty tests for extended length of stay, post-operative complications, and mortality

Frailty, as an age-related syndrome of reduced physiological reserve, contributes significantly to post-operative outcomes. With the aging population, frailty poses a significant threat to patients and health systems. Since 2012, preoperative frailty assessment has been recommended, yet its implementation has been inhibited by the vast number of frailty tests and lack of consensus. Since the anesthesiologist is the best placed for perioperative care, an anesthesia-tailored preoperative frailty test must be simple, quick, universally applicable to all surgeries, accurate, and ideally available in an app or online form. This systematic review attempted to rank frailty tests by predictive accuracy using the c-statistic in the outcomes of extended length of stay, 3-month post-operative complications, and 3-month mortality, as well as feasibility outcomes including time to completion, equipment and training requirements, cost, and database compatibility. Presenting findings of all frailty tests as a future reference for anesthesiologists, Clinical Frailty Scale was found to have the best combination of accuracy and feasibility for mortality with speed of completion and phone app availability; Edmonton Frailty Scale had the best accuracy for post-operative complications with opportunity for self-reporting. Finally, extended length of stay had too little data for recommendation of a frailty test. This review also demonstrated the need for changing research emphasis from odds ratios to metrics that measure the accuracy of a test itself, such as the c-statistic.

Preoperative evaluation of the elderly patient

Nowadays, the pre-operative evaluation of older patients is a critical step in the decision-making process. Clinical assessment and care planning should be considered a whole process rather than separate issues. Clinicians should use validated tools for pre-operative risk assessment of older patients to minimize surgery-related morbidity and mortality and enhance care quality. Traditional pre-operative consultation often fails to capture the pathophysiological and functional profiles of older patients. The elderly's pre-operative evaluation should be focused on determining the patient's functional reserve and reducing any possible peri-operative risk. Therefore, older adults may benefit from the Comprehensive Geriatric Assessment (CGA) that allows clinicians to evaluate several aspects of elderly life, such as depression and cognitive disorders, social status, multi-morbidity, frailty, geriatric syndromes, nutritional status, and polypharmacy. Despite the recognized challenges in applying the CGA, it may provide a realistic risk assessment for post-operative complications and suggest a tailored peri-operative treatment plan for older adults, including pre-operative optimization strategies. The older adults' pre-operative examination should not be considered a mere stand-alone, that is, an independent stage of the surgical pathway, but rather a vital step toward a personalized therapeutic approach that may involve professionals from different clinical fields. The aim of this review is to revise the evidence from the literature and highlight the most important items to be implemented in the pre-operative evaluation process in order to identify better all elderly patients' needs.

Frailty: the perioperative and anesthesia challenges of an emerging pandemic

Frailty is a complex and multisystem biological process characterized by reductions in physiological reserve. It is an increasingly common phenomena in the surgical population, and significantly impacts postoperative recovery. In this review, we will discuss the pathophysiology of frailty, as well as preoperative, intraoperative, and postoperative considerations for frailty care. We will also discuss the different models of postoperative care, including enhanced recovery pathways, as well as elective critical care admission. With discoveries of new effective interventions, and advances in healthcare information technology, optimized pathways could be developed to provide the best care possible that meets the challenges of perioperative frailty.

Assessing and managing frailty in emergency laparotomy: a WSES position paper

Many countries are facing an aging population. As people live longer, surgeons face the prospect of operating on increasingly older patients. Traditional teaching is that with older age, these patients face an increased risk of mortality and morbidity, even to a level deemed too prohibitive for surgery. However, this is not always true. An active 90-year-old patient can be much fitter than an overweight, sedentary 65-year-old patient with comorbidities. Recent literature shows that frailty-an age-related cumulative decline in multiple physiological systems, is therefore a better predictor of mortality and morbidity than chronological age alone. Despite recognition of frailty as an important tool in identifying vulnerable surgical patients, many surgeons still shun objective tools. The aim of this position paper was to perform a review of the existing literature and to provide recommendations on emergency laparotomy and in frail patients. This position paper was reviewed by an international expert panel composed of 37 experts who were asked to critically revise the manuscript and position statements. The position paper was conducted according to the WSES methodology. We shall present the derived statements upon which a consensus was reached, specifying the quality of the supporting evidence and suggesting future research directions.

The Outcome of Surgically Treated Proximal Femur Fractures Managed by Ortho-anesthetic Geriatric Care Pathway: A Prospective Observational Study with 2-Year Follow-Up

Background

Evaluation of the ortho-anesthetic geriatric care pathway for patients with proximal femur fracture in a tertiary care referral center was done by reporting the peri-operative morbidity and mortality. Clinical and demographic predictors of mortality were also identified in this cohort.

Material and Methods

This prospective observational study was conducted between August 2017 and November 2018. Demographic, anesthetic and surgical characteristics were recorded. Telephonic post-discharge follow-up was done for a period of 2 years. Factors predicting mortality were estimated using multivariate logistic regression.

Results

The cohort was characterized by frailty, high ASA physical status, NYHA class and Charlson co-morbidity index. The delay in presentation to hospital and subsequent surgical fixation was 7 (1-8) and 8 (5-13) days, respectively. The 30, 60, 90-day, 1-year and 2-year mortality was 13.6%, 21.8%, 25.45%, 36.5% and 44%, respectively. Intra-operative blood transfusion was a predictor of 30-day mortality (OR 9.2, 95% CI 1.02-83.17; p = 0.048). Pre-operative respiratory dysfunction predicted 60-day (OR 11.245, 95% CI 1.38-91.58; p = 0.024) and 90-day (OR 11.654, 95% CI 1.91-71.1; p = 0.008) mortality. Post-operative morbidity was reported in 31 (28.1%) patients; incidence of pneumonia (n = 9), sepsis (n = 8), MI (n = 6), PTE (n = 5) and ARF (n = 3) were 8.18%, 7.27%, 5.45%, 4.54% and 2.72%, respectively.

Conclusion

Existing pathway facilitated surgical fixation with median delay of 8 days which should be shortened to 48 h. High mortality in our cohort needs to be decreased by preventing admission delays and aggressively managing co-morbidities. Acceptable benchmark goals for pre-operative optimization of lung disease and decrease in intra-operative blood transfusion need to be incorporated in existing care pathway.

[Benefit of a Geriatric Evaluation before Operations, Interventions and Oncological Therapies]

Benefit of a Geriatric Evaluation before Operations, Interventions and Oncological Therapies Abstract: Older patients face an increased risk of complications and adverse outcomes during and after operations, interventions, and intense oncological therapies. At the same time, this patient group should not be excluded per se from potentially beneficial medical procedures based on chronological age alone. The timely identification of geriatric syndromes and increased vulnerability by means of comprehensive geriatric assessment is becoming increasingly important and is already recommended in the guidelines of professional societies of several medical disciplines. Nonetheless, the geriatric assessment should ideally be followed by proactive co-management in the sense of integrated care. The establishment of interdisciplinary and integrated care pathways for older hospital patients can contribute to significantly improved treatment outcomes. In addition to better patient-related outcomes and rising quality indicators, this approach may also offer positive health economic effects.

Geriatric care for surgical patients: results and reflections from a cross-sectional survey in acute Belgian hospitals

PURPOSE

To explore geriatric care for surgical patients in Belgian hospitals and geriatricians' reflections on current practice.

METHODS

A web-based survey was developed based on literature review and local expertise, and was pretested with 4 participants. In June 2021, the 27-question survey was sent to 91 heads of geriatrics departments. Descriptive statistics and thematic analysis were performed.

RESULTS

Fifty-four surveys were completed, corresponding to a response rate of 59%. Preoperative geriatric risk screening is performed in 25 hospitals and systematically followed by geriatric assessment in 17 hospitals. During the perioperative hospitalisation, 91% of geriatric teams provide non-medical and 82% provide medical advice. To a lesser extent, they provide geriatric protocols, geriatric education and training, and attend multidisciplinary team meetings. Overall, time allocation of geriatric teams goes mainly to postoperative evaluations and interventions, rather than to preoperative assessment and care planning. Most surgical patients are hospitalised on surgical wards, with reactive (73%) or proactive (46%) geriatric consultation. In 36 hospitals, surgical patients are also admitted on geriatric wards, predominantly orthopaedic/trauma, abdominal and vascular surgery. Ninety-eight per cent of geriatricians feel that more geriatric input for surgical patients is needed. The most common reported barriers to further implement geriatric-surgical services are shortage of geriatricians and geriatric nurses, and unadjusted legislation and financing.

CONCLUSION

Geriatric care for surgical patients in Belgian hospitals is mainly reactive, although geriatricians favour more proactive services. The main opportunities and challenges for improvement are to resolve staff shortages in the geriatric work field and to update legislation and financing.

The influence of frailty on outcomes for older adults admitted to hospital with benign biliary disease: a single-centre, observational cohort study

INTRODUCTION

The prevalence and complications of biliary disease increase with age. Frailty has been associated with adverse outcomes in the hospital setting. We describe the prevalence of frailty in older patients hospitalised with benign biliary disease and its association with duration of hospital stay, and 90-day and 1-year mortality.

METHODS

We performed a retrospective cohort study of patients aged 75 years and over admitted with acute biliary disease between 17 September 2014 and 20 March 2017. Clinical Frailty Scale (CFS) score was recorded on admission.

RESULTS

We included 200 patients with a median age of 82 (75-99) years, 60% were female; 154 (77%) were independent for personal activities of daily living (ADLs) and 99 (49.5%) for instrumental ADLs. Cholecystitis was the most common diagnosis (43%) followed by cholangitis (36%) and pancreatitis (21%). Ninety-nine patients were non frail (NF; CFS 1-4) and 101 were frail (F; CFS 5-9). Some 104 patients received medical treatment only. Surgery was more common in NF patients (11% vs F 2%), percutaneous drainage more frequently performed in F patients (15% vs NF 5%) and endoscopic cholangiopancreatography was similar in both groups (F 32% vs NF 31%). Frailty was associated with worse clinical outcomes in F vs NF: functional deconditioning (34% vs 11%), increased care level (19% vs 3%), length of stay (12 vs 7 days), 90-day mortality (8% vs 3%) and 1-year mortality (48% vs 24%).

CONCLUSIONS

Half of patients in our cohort were frail and spent longer in hospital, were less likely to undergo surgery and were less likely to remain alive at 1 year after discharge.

Severity of Dementia and Survival in Patients Diagnosed with Colorectal Cancer: A National Cohort Study in England and Wales

AIMS

There is little evidence about the survival of patients with colorectal cancer (CRC) also diagnosed with dementia. We quantified dementia severity and estimated how it is associated with 2-year overall survival.

MATERIALS AND METHODS

Records of patients aged 65 years or older diagnosed with CRC in England and Wales were identified. A novel proxy for dementia severity combined dementia diagnosis in administrative hospital data with Eastern Cooperative Oncology Group performance status. Cox regression was used to estimate hazard ratios with and without risk adjustment.

RESULTS

In total, 4033 of 105 250 CRC patients (3.8%) had dementia recorded. Two-year survival decreased with increasing dementia severity from 65.4% without dementia, 53.5% with mild dementia, 33.0% with moderate dementia to 16.5% with severe dementia (hazard ratio comparing severe with no dementia: 2.97; 95% confidence interval 2.79, 3.16). Risk adjustment for comorbidity and cancer stage reduced this association slightly (hazard ratio 2.52; 95% confidence interval 2.37, 2.68) and additional adjustment for treatment factors reduced it further (hazard ratio 1.60; 95% confidence interval 1.50, 1.70).

CONCLUSIONS

Survival of CRC patients varied strongly according to dementia severity, suggesting that a 'one-size-fits-all' policy for the care of CRC patients with dementia is not appropriate. Comprehensive assessment of cancer patients with dementia that considers dementia severity is essential in a shared decision-making process that ensures patients receive the most appropriate treatment for their individual needs and preferences.

Special orthopaedic geriatrics (SOG) - a new multiprofessional care model for elderly patients in elective orthopaedic surgery: a study protocol for a prospective randomized controlled trial of a multimodal intervention in frail patients with hip and knee replacement

BACKGROUND

Due to demographic change, the number of older people in Germany and worldwide will continue to rise in the coming decades. As a result, the number of elderly and frail patients undergoing total hip and knee arthroplasty is projected to increase significantly in the coming years. In order to reduce risk of complications and improve postoperative outcome, it can be beneficial to optimally prepare geriatric patients before orthopaedic surgery and to provide perioperative care by a multiprofessional orthogeriatric team. The aim of this comprehensive interventional study is to assess wether multimorbid patients can benefit from the new care model of special orthopaedic geriatrics (SOG) in elective total hip and knee arthroplasty.

METHODS

The SOG study is a registered, monocentric, prospective, randomized controlled trial (RCT) funded by the German Federal Joint Committee (GBA). This parallel group RCT with a total of 310 patients is intended to investigate the specially developed multimodal care model for orthogeriatric patients with total hip and knee arthroplasty (intervention group), which already begins preoperatively, in comparison to the usual orthopaedic care without orthogeriatric co-management (control group). Patients ≥70 years of age with multimorbidity or generally patients ≥80 years of age due to increased vulnerability with indication for elective primary total hip and knee arthroplasty can be included in the study. Exclusion criteria are age < 70 years, previous bony surgery or tumor in the area of the joint to be treated, infection and increased need for care (care level ≥ 4). The primary outcome is mobility measured by the Short Physical Performance Battery (SPPB). Secondary outcomes are morbidity, mortality, postoperative complications, delirium, cognition, mood, frailty, (instrumental) activities of daily living, malnutrition, pain, polypharmacy, and patient reported outcome measures. Tertiary outcomes are length of hospital stay, readmission rate, reoperation rate, transfusion rate, and time to rehabilitation. The study data will be collected preoperative, postoperative day 1 to 7, 4 to 6 weeks and 3 months after surgery.

DISCUSSION

Studies have shown that orthogeriatric co-management models in the treatment of hip fractures lead to significantly reduced morbidity and mortality rates. However, there are hardly any data available on the elective orthopaedic care of geriatric patients, especially in total hip and knee arthroplasty. In contrast to the care of trauma patients, optimal preoperative intervention is usually possible.

Intraoperative haemodynamics and postoperative intensive care unit admission in older patients with cancer

PURPOSE

Research on the impact of various intraoperative haemodynamic variables on the incidence of postoperative ICU admission among older patients with cancer is limited. In this study, the relationship between intraoperative haemodynamic status and postoperative intensive care unit admission among older patients with cancer is explored.

METHODS

Patients aged ≥75 who underwent elective oncologic surgery lasting ≥120min were analysed. Chi-squared and t-tests were used to assess the associations between intraoperative variables with postoperative intensive care unit admission. Multivariable regressions were used to analyse potential predict risk factors for postoperative intensive care unit admission.

RESULTS

Out of 994 patients, 48 (4.8%) were admitted to the intensive care unit within 30 days following surgery. Intensive care unit admission was associated with the presence of ≥4 comorbid conditions, intraoperative blood loss ≥100mL, and intraoperative tachycardia and hypertensive urgency. On multivariable analysis, operation time ≥240min (Odds Ratio [OR] = 2.29, p = 0.01), and each minute spent with intraoperative hypertensive urgency (OR = 1.06, p = 0.01) or tachycardia (OR = 1.01, p = 0.002) were associated with postoperative intensive care unit admission.

CONCLUSION

Intraoperative hypertensive urgency and tachycardia were associated with postoperative intensive care unit admission in older patients undergoing cancer surgery.

Which frailty scales for patients with adult spinal deformity are feasible and adequate? A systematic review

BACKGROUND CONTEXT

Frailty as a concept is not yet fully understood, and is not the same as comorbidity. It is associated with an increased risk of adverse events and mortality after surgery, which makes its preoperative assessment significant. Despite its relevance, it still remains unclear which scales are appropriate for use in patients with spinal pathology.

PURPOSE

To evaluate the feasibility and measurement properties of frailty scales for spine patients, specifically with adult spinal deformity (ASD), and to propose adequate scales for primary triage to prevent surgery in too frail patients and for preoperative assessment to modify patients' condition and surgical plans.

STUDY DESIGN/SETTING

Systematic review.

METHODS

Systematic search was performed between 2010 and 2021 including terms relating to spinal disorders, frailty scales, and methodological quality. Characteristics of the studies and frailty scales and data describing relation to treatment outcomes were extracted. The risk of bias was determined with the QAREL score.

RESULTS

Of the 1993 references found, 88 original studies were included and 23 scales were identified. No prospective interventional study was found where the preoperative frailty assessment was implemented. Predictive value of scales for surgical outcomes varied, dependent on spinal disorders, type of surgeries, patients' age and frailty at baseline, and outcomes. Seventeen studies reported measurement properties of eight scales but these studies were not free of bias. In 30 ASD studies, ASD-Frailty Index (ASD-FI, n=14) and 11-item modified Frailty Index (mFI-11, n=11) were most frequently used. These scales were mainly studied in registry studies including young adult population, and carry a risk of sample bias and make their validity in elderly population unclear. ASD-FI covers multidisciplinary concepts of frailty with 40 items but its feasibility in clinical practice is questionable due to its length. The Risk Analysis Index, another multidisciplinary scale with 14 items, has been implemented for preoperative assessment in other surgical domains and was proven to be feasible and effective in interventional prospective studies. The FRAIL is a simple questionnaire with five items and its predictive value was confirmed in prospective cohort studies in which only elderly patients were included.

CONCLUSIONS

No adequate scale was identified in terms of methodological quality and feasibility for daily practice. Careful attention should be paid when choosing an adequate scale, which depends on the setting of interest (eg triage or preoperative work-up). We recommend to further study a simple and predictive scale such as FRAIL for primary triage and a comprehensive and feasible scale such as Risk Analysis Index for preoperative assessment for patients undergoing spine surgery, as their adequacy has been shown in other medical domains.

Geriatric surgical service interventions in older emergency general surgery patients: Preliminary results

BACKGROUND

Older adults comprise an increasing proportion of emergency general surgery (EGS) admissions and face high morbidity and mortality. We created a geriatric surgical service with geriatric and palliative expertise to mitigate risks of hospitalization most hazardous to older patients. We sought to identify geriatric surgical service interventions most relevant to EGS patients.

METHODS

We prospectively identified patients ≥75 years admitted to the EGS service at an urban tertiary care hospital from January 2020-March 2021 who screened positive for frailty (FRAIL score ≥3 [scale 0-5, higher being worse]) or with cognitive impairment. A pilot geriatric surgical service, led by a dually-board certified geriatric and palliative care specialist, conducted a comprehensive geriatric assessment and modified Rockwood Frailty Index calculation for each eligible patient. Patient, hospital admission, and geriatric consultation characteristics were collected via chart review.

RESULTS

Fifty consecutive patients (median age 82 years [IQR 78-90], 56% female) received geriatric consultation (median time 3 days [IQR 1-6] from admission). The most common admission diagnosis was bowel obstruction (32%). Sixty-four percent of patients underwent ≥1 surgical procedure. Using the Frailty Index, 64% were moderately or severely frail. Interventions most frequently performed by the geriatric team included delirium prevention and management (66%), consideration of swallowing function (52%), individualized pain management (50%), and facilitation of serious illness conversations (58%).

CONCLUSIONS

Geriatric service involvement addresses a high burden of both geriatric and palliative care needs in older EGS patients. Geriatric recommendations may direct interventions for surgical education in fundamental geriatric and palliative care knowledge to maximize geriatric resources for the most high-risk patients.

Cognitive impairment and frailty screening in older surgical patients: a rural tertiary care centre experience

Introduction

Despite a clear association between cognitive impairment and physical frailty and poor postoperative outcomes in older adults, preoperative rates are rarely assessed. We sought to implement a preoperative cognitive impairment and frailty screening programme to meet the unique needs of our rural academic centre.

Methods

Through stakeholder interviews, we identified five primary drivers underlying screening implementation: staff education, technology infrastructure, workload impact, screening value and patient–provider communication. Based on these findings, we implemented cognitive dysfunction (AD8, Mini-Cog) and frailty (Clinical Frailty Scale) screening in our preoperative care clinic and select surgical clinics.

Results

In the preoperative care clinic, many of our patients scored positive for clinical frailty (428 of 1231, 35%) and for cognitive impairment (264 of 1781, 14.8%). In our surgical clinics, 27% (35 of 131) and 9% (12 of 131) scored positive for clinical frailty and cognitive impairment, respectively. Compliance to screening improved from 48% to 86% 1 year later.

Conclusion

We qualitatively analysed stakeholder feedback to drive the successful implementation of a preoperative cognitive impairment and frailty screening programme in our rural tertiary care centre. Preliminary data suggest that a clinically significant proportion of older adults screen positive for preoperative cognitive impairment and frailty and would benefit from tailored inpatient care.

Finding value with prehabilitation in older persons receiving surgery

PURPOSE OF REVIEW

Patients presenting for surgery are increasingly older and frail. Prehabilitation offers the best hope of preemptive functional optimisation to improve postoperative outcomes. Systematic reviews and meta-analyses show signals of improved function and reduced complications and length of stay, but are hampered by small trials with heterogeneous nature of interventions.

RECENT FINDINGS

The value proposition for prehabilitation is strengthened by applying the following considerations to the evidence. Multimodal prehabilitation programmes incorporating elements of exercise, nutrition, and psychological preparation have a sound physiological basis and will help standardise care delivery and evidence gathering. Targeting prehabilitation resources at high-risk patients may yield higher returns. Effective prehabilitation programmes must be individualised and pragmatic to address known barriers to adherence. The evidence for functional improvement is clear and this aligns with the values of older patients. A comprehensive analysis of value incorporates functional, quality of life, and cost outcomes in addition to conventional morbidity and mortality measures.

SUMMARY

Multimodal prehabilitation delivered by a multidisciplinary team improves functional outcomes following surgery. Function is an integral part of multidimensional value assessment including clinical and experiential measures. Future value enhancements include addressing frailty and overcoming barriers through targeted programme design.

Interdisciplinary Protocol for Surgery in Older Persons: Development and Implementation

As the population ages, more older adults will undergo surgical procedures, and common physiologic changes can raise the risk for surgical complications while increasing morbidity and mortality. In conjunction with the National Surgical Quality Improvement Program, we piloted a comprehensive and interdisciplinary assessment and intervention protocol for perioperative care for patients aged ≥75 years undergoing elective general, gynecology-oncologic, and orthopedic surgery. The intervention included screening tools for cognitive, functional, and nutritional deficits, a Geriatric Nurse Champion on each inpatient surgical unit, and an interdisciplinary Geriatric Surgery Quality Committee. Our intervention group was compared to surgical patients during the same time period 1 year prior to the intervention, and the groups were well matched in demographics and comorbidities. The intervention group had significantly higher rates of advance care plan documentation in analysis of all patients (P < .001) and in subgroup analysis of those 85 and older (P = .006). The preintervention group had less postoperative delirium compared to the postintervention group but it was not significant and there was no difference in length of stay between groups. Various explanations for the minimal impact of the protocol exist: small sample size, presence of other hospital initiatives to reduce pressure ulcer and delirium, and clinician's awareness of project planning that led to incorporating ideas prior to official implementation. Future research implementing this protocol in naïve and/or underperforming institutions may demonstrate a greater effect. Larger sample size as well as implementation in other surgical fields may reveal a significant impact. However, if additional study does not reveal a meaningful impact of a comprehensive geriatric assessment for surgical patients, then consideration must be made regarding unrecognized factors in surgical care for older adults or perhaps that factors cannot be mitigated in older adults because they are intrinsically a higher surgical risk.

Comprehensive geriatric assessment: outcomes of an advanced nurse practitioner-led service for older people requiring emergency surgery

A comprehensive geriatric assessment (CGA) is a holistic multidimensional review of older people living with frailty or at risk of frailty. In emergency surgical settings, CGAs can be used to identify medical issues and geriatric syndromes among older patients and consequently try to improve their post-operative outcomes. However, there is a lack of geriatrician input in hospitals beyond medical wards, which means that older people who need emergency surgery do not always undergo a CGA, with potential negative repercussions for their post-operative outcomes. One solution to this issue is to employ advanced nurse practitioners (ANPs) to deliver equivalent services. This article presents and discusses the results of an audit of an ANP-led CGA service for older people admitted to hospital for emergency surgery. The ANP reviewed 147 patients during the audit period and identified frailty in 37% and new medical issues in 89% of patients. Interventions initiated by the ANP based on the CGA included requests for additional investigations, referral to allied health professionals and discharge planning. The audit results suggest that ANPs can conduct CGAs in emergency surgical settings effectively.

Does Preoperative Cognitive Optimization Improve Postoperative Outcomes in the Elderly?

Perioperative neurocognitive disorder (PND) is a growing concern, affecting several million elderly patients each year in the United States, but strategies for its effective prevention have not yet been established. Humeidan et al. recently demonstrated that preoperative brain exercise resulted in a decrease in postoperative delirium incidence in elderly surgical patients, suggesting the potential of presurgical cognitive optimization to improve postoperative cognitive outcomes. This brief review summarizes the current knowledge regarding preoperative cognitive optimization and highlights landmark studies, as well as current ongoing studies, as the field is rapidly growing. This review further discusses the benefit of cognitive training in non-surgical elderly populations and the role of cognitive training in patients with preexisting cognitive impairment or dementia. The review also examines preclinical evidence in support of cognitive training, which can facilitate understanding of brain plasticity and the pathophysiology of PND. The literature suggests positive impacts of presurgical cognitive optimization, but further studies are encouraged to establish effective cognitive training programs for elderly presurgical patients.

Comparison of preoperative assessment tools in older patients undergoing cancer surgery: A prospective study

INTRODUCTION

Surgery in older adults with cancer is complex due to multiple age related confounding factors. There are many scoring systems available for preoperative risk stratifications of older patients. Currently very few prospective studies comparing the various commonly used scales are available. This is the first study which compares the established preoperative risk assessment tools of Eastern Cooperative Oncology Group Performance Scale (ECOG) and American Society of Anaesthesiologists Physical Status Scale (ASA) with frailty scores of Modified Frailty Index (MFI) and Clinical Frailty Scale (CFS).

MATERIAL AND METHODS

This is a prospective observational study of older patients with cancer who underwent oncosurgery in a tertiary cancer centre during the one-year study period. Patients were scored on the CFS, MFI, ASA and ECOG scales. All patients were followed up for 30 days immediately following surgery and their post operative complications were documented. Univariate and multivariate analyses were done and a p value of ≤0.05 was considered statistically significant.

RESULTS

Of the 820 patients studied, 15.6% had prolonged hospital stay, 9.1% had 30-day morbidity, 0.7% had readmission, and mortality was 1.1%. High-risk scores on the ASA and CFS were significantly associated with prolonged postoperative stay, readmission, morbidity, and mortality (p < 0.05). High-risk scores on the ECOG was significantly associated with prolonged hospital stay (p = 0.027), 30-day morbidity (p = 0.003), and mortality (p = 0.001), but not with readmission. There was no significant association between MFI score and the postoperative variables studied (p > 0.05). On multivariate analysis, morbidity was significantly associated only with male gender (p = 0.015), higher cancer stage (p = 0.005), higher ASA score (p = 0.029), and prolonged hospital stay (p = 0.001). Mortality was significantly associated only with emergency surgery (p = 0.012) and prolonged hospital stay (p = 0.004), and prolonged hospital stay was significantly associated with advanced cancer stage (p = 0.001) and emergency surgery (p = 0.02).

CONCLUSIONS

In older patients undergoing cancer surgery, ASA and CFS are predictors of prolonged postoperative stay, morbidity, mortality, and readmission. A high-risk ECOG score is predictive of prolonged post operative stay, 30-day morbidity, and mortality, but not of readmission. Score on MFI is not a predictor of postoperative outcomes. Newer predictive tools which include cancer- specific factors are required for better management of these patients.

Geriatric Preoperative Optimization: A Review

This review summarizes best practices for the perioperative care of older adults as recommended by the American Geriatrics Society, American Society of Anesthesiologists, and American College of Surgeons, with practical implementation strategies that can be readily implemented in busy preoperative or primary care clinics. In addition to traditional cardiopulmonary screening, older patients should undergo a comprehensive geriatric assessment. Rapid screening tools such as the Mini-Cog, Patient Health Questionnaire-2, and Frail Non-Disabled Survey and Clinical Frailty Scale, can be performed by multiple provider types and allow for quick, accurate assessments of cognition, functional status, and frailty screening. To assess polypharmacy, online resources can help providers identify and safely taper high-risk medications. Based on preoperative assessment findings, providers can recommend targeted prehabilitation, rehabilitation, medication management, care coordination, and/or delirium prevention interventions to improve postoperative outcomes for older surgical patients. Structured goals of care discussions utilizing the question-prompt list ensures that older patients have a realistic understanding of their surgery, risks, and recovery. This preoperative workup, combined with engaging with family members and interdisciplinary teams, can improve postoperative outcomes.

Effectiveness of Comanagement Model: Geriatric Medicine and Vascular Surgery

OBJECTIVES

Older surgical patients frequently develop postoperative complications due to their frailty and multiple comorbidities. Geriatric medicine consultation helps to optimize risk factors and improve outcomes in patients with hip fracture. This study aimed to evaluate patient outcomes before and after comanagement model implementation between geriatric medicine (Geriatric Surgical Service) and vascular surgery services.

DESIGN

This was a case-control study involving emergency vascular surgical patients who were comanaged by vascular surgery, geriatric medicine, and geriatric nursing services.

SETTINGS AND PARTICIPANTS

This study was conducted in a tertiary hospital in Singapore from 2015 to 2018 with acute vascular surgical patients aged older than 65 years.

METHODS

A retrospective cohort of 135 patients from 2013 to 2014 (control group) who fulfilled the criteria for the comanagement model was compared with a prospective cohort of 348 patients who were comanaged by a geriatric surgical service from 2015 to 2018, and a further subgroup analysis of patients between 2015 and 2016 (n = 150) (early intervention group) and between 2017 and 2018 (n = 198) (late intervention group) was performed.

RESULTS

Comanaged patients had a significantly shorter length of hospital stay (11.6 vs 20.8 days, P = .001), reduced nosocomial infections (3% vs 12% for urinary tract infection, P = .003) and decreased 30-day readmission rates (22% vs 34%, P = .011). A trend of a decreased incidence of fluid overload was noted in patients comanaged with the geriatric surgical service (3% vs 7%, P = .073). Subgroup analysis showed progressive reductions in the length of stay (15.4 vs 11.6 days, P = .001), 30-day readmission rate (35% vs 22%, P = .01), and nosocomial urinary tract infection (8% vs 3%, P = .003) between the early intervention group and the late intervention group. Although they were not statistically significant, reductions were also observed in the delirium rate (13% vs 11%) and other postoperative medical complications in the early intervention group and the late intervention group.

CONCLUSION AND IMPLICATIONS

Despite having increasing comorbidities, older vascular surgical inpatients had a significantly shorter length of stay, reduced nosocomial infections, and decreased 30-day readmission rates through a comanagement model with vascular surgery and geriatric medicine services. Improvements in outcomes were observed over time as the model of care evolved. Geriatric medicine intervention in the perioperative period improves the outcomes of older acute vascular surgical patients.

Improving Outcomes for Elderly Patients Following Emergency Surgery: a Cutting-edge Review

Purpose of Review

The aim of this review is to explore the consequence of emergency general surgery in the elderly, and to summarise recent developments in the pre-, peri- and postoperative management of these patients, in order to improve outcomes.

Recent Findings

Preoperatively, accurate risk assessment is vital to ensure the right patients undergo emergency surgery. Perioperatively, there are multiple interventions specific to elderly patients that have been shown to improve outcomes. Postoperatively, elderly patients must be cared more in an appropriate setting in order to avoid failure to rescue and promote return to function.

Summary

This review of contemporary evidence identifies multiple pre-, peri- and postoperative interventions that can improve outcomes for elderly patients after emergency general surgery. These evidence-based recommendations should help direct care of elderly patients undergoing emergency surgery and foster further quality improvement measures and research investigations.

Comprehensive Geriatric Assessment and Exercise Capacity in Cardiac Rehabilitation for Patients Referred to Transcatheter Aortic Valve Implantation

Comprehensive geriatric assessment (CGA)-based cardiac rehabilitation (CR) program is essential for patients before and after transcatheter aortic valve implantation (TAVI). This study aimed to explore the values of CGA and exercise capacity in CR for patients referred to TAVI. A retrospective analysis was conducted in 90 patients referred to TAVI from January to October 2019. CR strategies started before TAVI. The association between clinical characteristics, CGA, and change in six-minute walk distance (Δ6MWD) was analyzed with multivariate regression models. Most of patients had cognitive impairment (50%), malnutrition (61%), and frailty (83%). After the CR, the proportion of cognitive impairment, malnutrition, and frail patients was significantly decreased by 21%, 40%, and 57%, respectively (p = 0.002, p <0.001, p <0.001). The 6MWD at a month after discharge (291.9 ± 98.8 m) was significantly improved than that at discharge after TAVI (218.8 ± 114.3m, p <0.001). The multivariate regression analysis indicated body mass index (BMI; Δ6MWD:12.0, 95% confidence interval [CI] 0.3 to 23.8, p = 0.045), frailty (Δ6MWD: -57.9, 95% CI -81.8 to -34.1, p <0.001) and malnutrition (Δ6MWD: -25.1, 95% CI -47.0 to -3.2, p = 0.026) as the associated predictors of Δ6MWD. In conclusion, functional status in patients referred to TAVI could be improved by CGA-based CR. BMI, frailty, and malnutrition were associated with the efficacy of CR on exercise capacity. CGA can play the important role in the evaluation and making strategies for CR in patients.

The Association Between Hearing Loss and Surgical Complications in Older Adults

OBJECTIVES

In this study, we sought to evaluate whether older patients with hearing loss who underwent surgery were at greater risk of postsurgical complications, increased inpatient length-of-stay (LOS), and hospital readmission.

DESIGN

This was a retrospective cohort study of patients receiving surgery at a tertiary medical center. Utilizing electronic health record data from two merged datasets, we identified patients 65 years and older, undergoing major surgery between January 1, 2014 and January 31, 2017, and who had audiometric evaluation before surgery. Patients were classified as having either normal hearing or hearing loss based on pure-tone average in the better ear. A Generalized Estimating Equations approach was used to fit multivariable regression models for outcome variables of interest.

RESULTS

Of patients ≥65 years undergoing major surgery in our time frame, a total of 742 surgical procedures were performed on 621 patients with available audiometric data. After adjusting for age, sex, race, and comorbidities, hearing loss was associated with an increase in the odds of developing postoperative complications. Every 10 dB increase in hearing loss was associated with a 14% increase in the odds of developing a postoperative complication (odds ratio = 1.14, 95% confidence interval = 1.01-1.29, p = 0.031). Hearing loss was not significantly associated with increased hospital LOS, 30-day readmission, or 90-day readmission.

CONCLUSION

Hearing loss was significantly associated with developing postoperative complications in older adults undergoing major surgery. Screening for hearing impairment may be a useful addition to the preoperative assessment and perioperative management of older patients undergoing surgery.

Behaviours of older adults and caregivers preparing for elective surgery: a virtually conducted mixed-methods research protocol to improve surgical outcomes

INTRODUCTION

Older adults (age ≥65 years) are pursuing increasingly complex, elective surgeries; and, are at higher risk for intraoperative and postoperative complications. Patients and their caregivers frequently struggle with the postoperative recovery process at home, which may contribute to complications. We aim to identify opportunities to intervene during the preoperative period to improve postoperative outcomes by understanding the preparatory behaviours of older adults and their caregivers before a complex, elective surgery.

METHODS AND ANALYSIS

As a result of the COVID-19 pandemic, we will conduct this study via telephone and videoconferencing. Using a multiphase mixed-methods research design, we will collect data on 10-15 patient-caregiver dyads from a pool of older adults (across a spectrum of cognitive abilities) scheduled for an elective colorectal surgery between 1 July 2020 and 30 May 2021. We will collect quantitative and qualitative data before (T1, T2) and after (T3, T4) surgery. Preoperatively, participants will each complete a cognitive assessment and a semi-structured qualitative interview that focuses on their preparatory behaviours (T1). They will then answer questionnaires about mood, self-efficacy and home environment (T2). Three weeks following hospital discharge, participants will complete another qualitative interview focusing on a comparison of preoperative and postoperative preparedness (T3). Researchers will also collect information about the patient's medical conditions, the postoperative complications and healthcare utilisation from the patient's chart 30 days following discharge (T4). We will code and conduct thematic analysis of the qualitative data to identify salient themes. Quantitative data will be analysed using basic descriptive statistics to characterise the participants. We will integrate the qualitative and quantitative findings using results from the quantitative scales to group participants and with use of joint display analysis.

ETHICS AND DISSEMINATION

Ethics approval was obtained from the University of Michigan IRB. Study findings will be disseminated through peer-reviewed journals and presentations at conferences.

Aortic valve replacement among patients with Alzheimer's disease and related dementias

BACKGROUND

Transcatheter aortic valve replacement (TAVR) has made palliation from aortic stenosis more broadly available to populations previously thought to be too high risk for surgery, such as those with Alzheimer's disease and related dementias (ADRD); however, its safety and effectiveness in this context are uncertain.

METHODS

We performed a retrospective cohort study of national Medicare beneficiaries, aged 66 and older with Parts A and B, between 2010 and 2016. Patients undergoing AVR were identified, and follow-up was available through 2017. Multivariable regression was used to measure the independent association between having a diagnosis of ADRD at the time of AVR, stratified by TAVR and surgery, and outcomes (mortality and Medicare institutional days at 1 year after AVR).

RESULTS

The average rate of increase in AVR per year was 17.5 cases per 100,000 ADRD and 8.4 per 100,000 non-ADRD beneficiaries, largely driven by more rapid adoption of TAVR. Adjusted mortality following AVR declined significantly between those treated in 2010 and 2016, from 13.5% (95% CI 10.2%-17.7%) to 6.3% (95% CI 5.2%-7.6%) and from 13.7% (95% CI 12.7%-14.7%) to 6.3% (95% CI 5.8%-6.9%) in those with and without ADRD, respectively. The sharpest decline was noted for patients undergoing TAVR between 2011 and 2016, with adjusted mortality declining from 19.9% (95% CI 11.2%-32.8%) to 5.2% (95% CI 4.1%-6.5%) and from 12.2% (95% CI 9.3%-15.8%) to 5.0% (95% CI 4.4%-5.6%) in patients with and without ADRD, respectively. Similar declines were evident for Medicare institutional days in the year after AVR in both patient groups.

CONCLUSIONS

Rates of AVR in those with ADRD increased during the past decade largely driven by the diffusion of TAVR. The use of TAVR in this vulnerable population did not come at the expense of increasing Medicare institutional days or mortality at 1-year.

The Clinical Frailty Scale is a useful tool for predicting postoperative complications following elective colon cancer surgery at the age of 80 years and above: A prospective, multicentre observational study

AIM

Identification of the risks of postoperative complications may be challenging in older patients with heterogeneous physical and cognitive status. The aim of this multicentre, observational study was to identify variables that affect the outcomes of colon cancer surgery and, especially, to find tools to quantify the risks related to surgery.

METHOD

Patients aged ≥80 years with electively operated Stage I-III colon cancer were recruited. The prospectively collected data included comorbidities, results of the onco-geriatric screening tool (G8), Clinical Frailty Scale (CFS), Charlson Comorbidity Index (CCI) and Mini Nutritional Assessment-Short Form (MNA-SF), and operative and postoperative outcomes.

RESULTS

A total of 161 patients (mean 84.5 years, range 80-97, 60% female) were included. History of cerebral stroke (64% vs. 37%, p = 0.02), albumin level 31-34 g/l compared with ≥35 g/l (57% vs. 32%, p = 0.007), CFS 3-4 and 5-9 compared with CFS 1-2 (49% and 47% vs. 16%, respectively) and American Society of Anesthesiologists score >3 (77% vs. 28%, P = 0.006) were related to a higher risk of complications. In multivariate logistic regression analysis CFS ≥3 (OR 6.06, 95% CI 1.88-19.5, p = 0.003) and albumin level 31-34 g/l (OR 3.88, 1.61-9.38, p = 0.003) were significantly associated with postoperative complications. Severe complications were more common in patients with chronic obstructive pulmonary disease (43% vs. 13%, p = 0.047), renal failure (25% vs. 12%, p = 0.021), albumin level 31-34 g/l (26% vs. 8%, p = 0.014) and CCI >6 (23% vs. 10%, p = 0.034).

CONCLUSION

Surgery on physically and cognitively fit aged colon cancer patients with CFS 1-2 can lead to excellent operative outcomes similar to those of younger patients. The CFS could be a useful screening tool for predicting postoperative complications.

Surgical and functional outcomes and survival following Colon Cancer surgery in the aged: a study protocol for a prospective, observational multicentre study

Background

The number of colorectal cancer patients increases with age. The decision to go through major surgery can be challenging for the aged patient and the surgeon because of the heterogeneity within the older population. Differences in preoperative physical and cognitive status can affect postoperative outcomes and functional recovery, and impact on patients’ quality of life.

Methods / design

A prospective, observational, multicentre study including nine hospitals to analyse the impact of colon cancer surgery on functional ability, short-term outcomes (complications and mortality), and their predictors in patients aged ≥80 years. The catchment area of the study hospitals is 3.88 million people, representing 70% of the population of Finland. The data will be gathered from patient baseline characteristics, surgical interventional data, and pre- and postoperative patient-questionnaires, to an electronic database (REDCap) especially dedicated to the study.

Discussion

This multicentre study provides information about colon cancer surgery’s operative and functional outcomes on older patients. A further aim is to find prognostic factors which could help to predict adverse outcomes of surgery.

Patient reported outcomes in an elder-friendly surgical environment: Prospective, controlled before-after study

Introduction

The Acute Care for the Elderly (ACE) model has demonstrated clinical benefit, but there is little evidence regarding quality of life after discharge. The Elder-friendly Approaches to the Surgical Environment (EASE) study was conducted to assess implementation of an ACE unit on an acute surgical service. Improved clinical and economic outcomes have been demonstrated, but post-discharge patient reported outcomes have not yet been reported.

Methods

Prospective, concurrently controlled, before-after study at two tertiary care hospitals in Alberta, Canada. The SF-12, EQ-5D, Canadian Malnutrition Screening Tool (CMST) and patient satisfaction were collected from elderly (≥ 65 years old) patients, 6 weeks and 6 months after discharge from an acute care surgical service. A difference-in-difference (DID) method was used to analyze between-site effects.

Results

At six weeks, patient satisfaction was high at 68%-86%, with significant improvement Pre-to Post-EASE at the control site (p < 0.001), but not the intervention site (p = 0.06). For the intervention site, within-site adjusted pre-post effects were nonsignificant for all patient reported outcomes [EQ-Index Score β coefficient (SE): 0.042 (0.022); EQ-Visual Analog Scale: 0.10 (2.14); SF-12 Physical Component Score: -0.57 (0.84); SF-12 Mental Component Score: 1.17 (0.84); CMST Score: -0.39 (0.34)]. DID analyses were also non significant for all outcomes except for SF-12 Mental Component Score (p < 0.001).

Conclusion

The clinically and economically beneficial EASE interventions do not appear to compromise quality of life, risk for malnutrition, or patient satisfaction in the post-discharge period. Further research with larger sample size is needed with comparisons to pre-intervention and the early post-discharge period.

Care of Older People in Surgery for general surgery: a single centre experience

BACKGROUND

Older patients undergoing emergency surgery experience higher mortality and morbidity. 'Care of Older People in Surgery' (COPS) is a comprehensive geriatric care model developed for acute surgical units (ASU) to improve clinical outcomes in older general surgical patients. This study aimed to evaluate the impact of COPS on clinical and health service outcomes in an Australian hospital.

METHODS

The before-and-after study was conducted in the ASU, at Nepean Hospital. Data from patients ≥75 years admitted for >24 h into the ASU during the intervention period between April 2017 and March 2018 were compared to patients admitted in the previous year (April 2016 to March 2017) prior to the COPS intervention (n = 212). Health service outcomes measured include the average stay length, medical emergency team response, unplanned intensive care unit admission and 28-day readmission rates.

RESULTS

The COPS group (n = 214) suffered significantly fewer medical complications, including less acute kidney injuries, arrhythmias and urinary tract infections compared to the pre-intervention cohort (n = 212). Medical emergency team activation was significantly reduced after COPS model implementation and the average length of stay decreased. However, the incidence of postoperative delirium and acute coronary syndrome were higher in COPS cohort.

CONCLUSION

Our study demonstrated that comprehensive geriatric assessment and care delivered through a shared model of care in older general surgical patients improved clinical outcome and patient safety measures.
