Optimal Perioperative Management of the Geriatric Patient: A Best Practices Guideline from the American College of Surgeons NSQIP and the American Geriatrics Society

Liver transplantation in the patient with physical frailty

Frailty is a decline in functional reserve across multiple physiological systems. A key component of frailty is sarcopenia, which denotes a loss of skeletal muscle mass and impaired contractile function that ultimately result in physical frailty. Physical frailty/sarcopenia are frequent and contribute to adverse clinical outcomes before and after liver transplantation. Frailty indices, including the liver frailty index, focus on contractile dysfunction (physical frailty), while cross-sectional image analysis of muscle area is the most accepted and reproducible measure to define sarcopenia. Thus, physical frailty and sarcopenia are interrelated. The prevalence of physical frailty/sarcopenia is high in liver transplant candidates and these conditions have been shown to adversely impact clinical outcomes including mortality, hospitalisations, infections, and cost of care both before and after transplantation. Data on the prevalence of frailty/sarcopenia and their sex- and age-dependent impact on outcomes are not consistent in patients on the liver transplant waitlist. Physical frailty and sarcopenic obesity are frequent in the obese patient with cirrhosis, and adversely affect outcomes after liver transplantation. Nutritional interventions and physical activity remain the mainstay of management before and after transplantation, despite limited data from large scale trials. In addition to physical frailty, there is recognition that a global evaluation including a multidisciplinary approach to other components of frailty (e.g., cognition, emotional, psychosocial) also need to be addressed in patients on the transplant waitlist. Recent advances in our understanding of the underlying mechanisms of sarcopenia and contractile dysfunction have helped identify novel therapeutic targets.

Disparities in advance care planning rates persist among emergency general surgery patients: Current state and recommendations for improvement

BACKGROUND

Unanticipated changes in health status and worsening of chronic conditions often prompt the need to consider emergency general surgery (EGS). Although discussions about goals of care may promote goal-concordant care and reduce patient and caregiver depression and anxiety, these conversations, as well as standardized documentation, remain infrequent for EGS patients.

METHODS

We conducted a retrospective cohort study using electronic health record data from patients admitted to an EGS service at a tertiary academic center to determine the prevalence of clinically meaningful advance care planning (ACP) documentation (conversations and legal ACP forms) during the EGS hospitalization. Multivariable regression was performed to identify patient, clinician, and procedural factors associated with the lack of ACP.

RESULTS

Among 681 patients admitted to the EGS service in 2019, only 20.1% had ACP documentation in the electronic health record at any time point during their hospitalization (of those, 75.5% completed before and 24.5% completed during admission). Two thirds (65.8%) of the total cohort had surgery during their admission, but none of them had a documented ACP conversation with the surgical team preoperatively. Patients with ACP documentation tended to have Medicare insurance (adjusted odds ratio, 5.06; 95% confidence interval, 2.09-12.23; p < 0.001) and had greater burden of comorbid conditions (adjusted odds ratio, 4.19; 95% confidence interval, 2.55-6.88; p < 0.001).

CONCLUSION

Adults experiencing a significant, often abrupt change in health status leading to an EGS admission are infrequently engaged in ACP conducted by the surgical team. This is a critical missed opportunity to promote patient-centered care and to communicate patients' care preferences to the surgical and other inpatient medical teams.

Laparoscopic treatment of ventral hernias: the Italian national guidelines

Primary and incisional ventral hernias are significant public health issues for their prevalence, variability of professional practices, and high costs associated with the treatment In 2019, the Board of Directors of the Italian Society for Endoscopic Surgery (SICE) promoted the development of new guidelines on the laparoscopic treatment of ventral hernias, according to the new national regulation. In 2022, the guideline was accepted by the government agency, and it was published, in Italian, on the SNLG website. Here, we report the adopted methodology and the guideline's recommendations, as established in its diffusion policy. This guideline is produced according to the methodology indicated by the SNGL and applying the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) methodology. Fifteen recommendations were produced as a result of 4 PICO questions. The level of recommendation was conditional for 12 of them and conditional to moderate for one. This guideline's strengths include relying on an extensive systematic review of the literature and applying a rigorous GRADE method. It also has several limitations. The literature on the topic is continuously and rapidly evolving; our results are based on findings that need constant re-appraisal. It is focused only on minimally invasive techniques and cannot consider broader issues (e.g., diagnostics, indication for surgery, pre-habilitation).

[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.

Understanding Outcomes After Major Surgery

The global volume of surgery is increasing. Adverse outcomes after surgery have resource implications and long-term impact on quality of life and consequently represent a significant and underappreciated public health issue. Standardization of outcome reporting is essential for evidence synthesis, risk stratification, perioperative care planning, and to inform shared decision-making. The association between short- and long-term outcomes, which persists when corrected for base-line risk, has significant implications for patients and providers and warrants further investigation. Candidate mechanisms include sustained inflammation and reduced physician activity, which may, in the future, be mitigated by targeted interventions.

Perioperative Neurocognitive Disorders in Adults Requiring Cardiac Surgery: Screening, Prevention, and Management

Neurocognitive changes are the most common complication after cardiac surgery, ranging from acute postoperative delirium to prolonged postoperative neurocognitive disorder. Changes in cognition are distressing to patients and families and associated with worse outcomes overall. This review outlines definitions and diagnostic criteria, risk factors for, and mechanisms of Perioperative Neurocognitive Disorders and offers strategies for preoperative screening and perioperative prevention and management of neurocognitive complications.

Patient-Reported Symptom Burden After Cancer Surgery in Older Adults: A Population-Level Analysis

BACKGROUND

Older adults have unique needs for supportive care after surgery. We examined symptom trajectories and factors associated with high symptom burden after cancer surgery in older adults.

PATIENTS AND METHODS

We conducted a population-level study of patients ≥ 70 years old undergoing cancer surgery (2007-2018) using prospectively collected Edmonton Symptom Assessment System (ESAS) scores. The monthly prevalence of moderate to severe symptoms (ESAS ≥ 4) for anxiety, depression, drowsiness, lack of appetite, nausea, pain, shortness of breath, tiredness, and poor wellbeing was computed over 12 months after surgery.

RESULTS

Among 48,748 patients, 234,420 ESAS scores were recorded over 12 months after surgery. Moderate to severe tiredness (57.8%), poor wellbeing (51.9%), and lack of appetite (39.3%) were most common. The proportion of patients with moderate to severe symptoms was stable over the 1 month prior to and 12 months after surgery (< 5% variation for each symptom). There was no clinically significant change (< 5%) in symptom trajectory with the initiation of adjuvant therapy.

CONCLUSIONS

Patient-reported symptom burden was stable for up to 1 year after cancer surgery among older adults. Neither surgery nor adjuvant therapy coincided with a worsening in symptom burden. However, the persistence of symptoms at 1 year may suggest gaps in supportive care for older adults. This information on symptom trajectory and predictors of high symptom burden is important to set appropriate expectations and improve patient counseling, recovery care pathways, and proactive symptom management for older adults after cancer surgery.

Evaluation of interdisciplinary care pathway implementation in older elective surgery patients

BACKGROUND

The American College of Surgeons Geriatric Surgery Verification Program outlines best practices for surgical care in older adults. These recommendations have guided institutions to create workflows to better support needs specific to older surgical patients. This qualitative study explored clinician experiences to understand influences on implementation of frailty screening and an interdisciplinary care pathway in older elective colorectal surgery and neurosurgery patients.

STUDY DESIGN

Semi-structured in-person and video-based interviews were conducted from July 2021 to March 2022 with clinicians caring for patients ≥70 years on the colorectal surgery and neurosurgery services. Interviews addressed familiarity with and beliefs about the intervention, intervention alignment with routine workflow and workflow adaptations, and barriers and facilitators to performing the intervention. Interviews were analyzed using the consolidated framework for implementation research (CFIR) to find themes related to ongoing implementation.

RESULTS

Thirty-two clinicians participated (56.3% female, 58.8% White). Fifteen relevant CFIR constructs were identified. Key themes to implementation success included strong participant belief in effectiveness of the intervention and its advantage over standard care; the importance of training, reference materials, and champions; and the need for institution-level investment in resources to amplify the impact of the intervention on patients and expand the capacity to address their needs.

CONCLUSION

Systematic evaluation found implementation of frailty screening and an interdisciplinary care pathway in elective colorectal surgery and neurosurgery patients to be supported by participating clinicians, yet sustainability of the intervention and further adoption across surgical services to better meet the needs of older patients would necessitate organizational resource allocation.

Cognitive status predicts preoperative instruction compliance

The most common postoperative complication for older adults is perioperative neurocognitive disorder (PNCD). Its greatest risk factor is preoperative cognitive impairment. Cognitive impairment also predicts higher likelihood of postoperative complications. While the cause of disparity in outcomes is likely multifactorial, the ability to correctly follow perioperative instructions may be one modifiable component. The purpose of this study was to determine whether cognitive impairment led to reduced preoperative instruction compliance and if so, identify barriers and enact a tailored care-plan to close the gap. Our preoperative clinic implemented routine Mini-Cog screening to identify older (age ≥ 65) surgical patients at increased risk. All patients received the same instructions and, on day of surgery, were surveyed to determine correct execution of nil per os guidelines, chlorhexidine wipe use and medication management. Data was stratified by cognitive status to evaluate whether impairment predicted instruction execution. Feedback from patients and families were compiled. Of those who screened negative for impairment, 68% correctly followed instructions, while 84.2% of those impaired struggled with ≥1 instruction(s); impaired patients were more likely to incorrectly follow instructions (OR = 10.5, p-value = 0.001). Areas for change were identified and team-based solutions were enacted with additional support for those with impairment. We found a clear difference in correct execution with respect to cognitive status. By improving instructions as an institution and adding additional support for those with impairment, the compliance gap was significantly reduced. Targeting perioperative instructions and tailoring care in this population may be one modifiable component in the outcome disparity they face.

Gastric adenocarcinoma with high‑level microsatellite instability: A case report

Gastric cancer (GC) ranks fifth on the list of the most common malignancies worldwide. In Peru, gastric neoplasms are considered the second leading cause of mortality among males. Among the molecular subgroups of GC, microsatellite instability presents a favorable prognosis due to its hypermutated phenotype, which activates immunosurveillance. The present study describes the case of a 75-year-old patient, who was admitted in the hospital with a history of upper gastrointestinal bleeding and recurrent hospital admission, due to severe anemia. The patient presented with pale skin, normal vital functions, slight swelling of the lower extremities, and abdominal distention and bloating upon a physical examination. An endoscopic examination revealed an infiltrating circular ulcerated lesion. The histopathological analysis identified a moderately differentiated intestinal-type adenocarcinoma with pathological stage T3N0M0. Tumor genomic profiling demonstrated alterations in 15 different genes with a tumor mutational burden of 28 mutations/Mb. Finally, the patient underwent a partial gastrectomy without pre-operative chemotherapy. After 4 days, the patient presented with post-operative complications for which he was re-operated on. The patient did not survive. To the best of our knowledge, in the present case, pernicious anemia was an early sign of GC and a gastroscopy had to be performed. Furthermore, MutS homolog 3 alterations probably conditioned the presence of multiple frame-shift mutations.

Age-Related Perioperative Neurocognitive Disorders: Experimental Models and Druggable Targets

With the worldwide increase in life span, surgical patients are becoming older and have a greater propensity for postoperative cognitive impairment, either new onset or through deterioration of an existing condition; in both conditions, knowledge of the patient's preoperative cognitive function and postoperative cognitive trajectory is imperative. We describe the clinical utility of a tablet-based technique for rapid assessment of the memory and attentiveness domains required for executive function. The pathogenic mechanisms for perioperative neurocognitive disorders have been investigated in animal models in which excessive and/or prolonged postoperative neuroinflammation has emerged as a likely contender. The cellular and molecular species involved in postoperative neuroinflammation are the putative targets for future therapeutic interventions that are efficacious and do not interfere with the surgical patient's healing process.

Comparison of oncological outcomes in elderly early-stage cervical cancer patients treated with radical surgery or radiotherapy: A real-world retrospective study with propensity score matching

Objective

To compare the oncological outcomes of radical surgery and radical radiotherapy in elderly (over 65 years) patients with early-stage cervical cancer (IB-IIA).

Methods

Elderly patients with stage IB-IIA cervical cancer treated at Peking Union Medical College Hospital from January 2000 to December 2020 were retrospectively reviewed. All patients were divided into the radiotherapy group (RT group) and the operation group (OP group) according to their primary intervention. Propensity score matching (PSM) analysis was performed to balance the biases. The primary outcome was overall survival (OS), and the secondary outcomes were progression-free survival (PFS) and adverse effects.

Results

A total of 116 patients were eligible for the study (47 in the RT group, and 69 in the OP group), and after PSM, 82 patients were suitable for further analysis (37 in the RT group, and 45 in the OP group). In the real-world setting, it was found that compared with radiotherapy, operation was more frequently selected for elderly cervical cancer patients with adenocarcinoma (P < 0.001) and IB1 stage cancer (P < 0.001). The 5-year PFS rates between the RT and OP groups were not significant (82.3% vs. 73.6%, P = 0.659), and the 5-year OS rate of the OP group was significantly better than that in the RT group (100% vs. 76.3%, P = 0.039), especially in patients with squamous cell carcinoma (P = 0.029) and tumor size of 2~4 cm with G2 differentiation (P = 0.046). There was no significant difference in PFS between the two groups (P = 0.659). In the multivariate analysis, compared with operation, radical radiotherapy was an independent risk factor of OS (hazard ratio = 4.970, 95% CI, 1.023~24.140, P = 0.047). No difference was observed in adverse effects between the RT and OP groups (P = 0.154) and in ≥grade 3 adverse effects (P = 0.852).

Conclusion

The study found that surgery was more frequently selected for elderly cervical cancer patients with adenocarcinoma and IB1 stage cancer in the real-world setting. After PSM to balance the biases, it showed that compared with radiotherapy, surgery could improve the OS of elderly early-stage cervical cancer patients and was an independent protective factor of OS in elderly early-stage cervical cancer patients.

Recent advances in geriatric anaesthesia

The World Health Organization defines healthy ageing as 'the process of developing and maintaining the functional ability that enables well-being in older age'. This functional ability is the characteristic of the individual's own physical and mental status influenced by the environmental and socio-economic factors. Preoperative preparation of the elderly patients includes functional assessment to identify preexisting cognitive impairment or cardio-pulmonary reserve, frailty, nutrition, polypharmacy and anti-coagulation issues. Intraoperative management includes anaesthetic mode and pharmacology, monitoring, intravenous fluid and transfusion management, lung protective ventilation and hypothermia. Postoperative checklist includes perioperative analgesia, postoperative delirium and cognitive dysfunction.

Postoperative delirium in older patients after undergoing pelvic organ prolapse surgery

INTRODUCTION AND HYPOTHESIS

To determine the 7-day incidence and risk factors of postoperative delirium (POD) occurring after prolapse surgery in women aged ≥60 years.

METHODS

A prospective study of women ≥60 years undergoing prolapse surgery at a large academic center. The primary outcome is positive Confusion Assessment Method delirium screen administered in person or by telephone at the time of hospital discharge and postoperative days 1, 3, 5, and 7.

RESULTS

This analysis included 165 patients, mean ± SD age of 72.5 ± 6.1 years, with median (IQR) years of education of 13 (12-16), and baseline Modified Mini-Mental Status (3MS) Exam score of 95 (92-98). Prolapse repair type was vaginal for 70% (n=115) and laparoscopic for 30% (n=50) of patients; most under general anesthesia, 151 (92.1%). The incidence of positive delirium screen during the first week after surgery was 12.1% (n=20). Most of these participants screened positive on postoperative day 0, 8.4% (n=14). In univariate analyses, a positive screen was associated with older age and fewer education years, lower 3MS exam score, greater baseline geriatric depression scale score, and greater frailty score. Lower 3MS score was the only variable that remained significant in the final model (adjusted odds ratio 0.84, 95% CI 0.75-0.95).

CONCLUSIONS

One in 12 women ≥60 years deemed eligible for discharge on the day of prolapse surgery screens positive for delirium. The 7-day POD incidence is comparable to other elective non-cardiac surgery cohorts. Given the increasing trend toward same day discharge after major prolapse surgery, more research is needed to determine the impact of universal delirium screening as part of discharge assessments.

[Vascular surgery in old people]

The age pyramid in Germany is upside down. According to the Federal Statistical Office this development will continue in the coming years, which presents a challenge for surgeons to surgically treat increasingly more and increasingly older people. Particularly in vascular surgery, which is a surgery of old people, this fact represents a special challenge. The frailty of old people is, among other things, due to a series of comorbidities, which must be taken into consideration within the framework of surgical treatment. They can have an important influence on the perioperative planning, the operation, the postoperative treatment and the outcome of the patient. This treatment planning becomes more and more challenging, because due to the progress in endovascular surgery there will soon be no limits to what is feasible; however, the question arises whether the feasible is also reasonable? Within the scope of this article the authors try to give answers to the treatment of old patients in vascular surgery and to find strategies for planning and to establish an individualized optimal treatment.

A novel approach for the detection of cognitive impairment and delirium risk in older patients undergoing spine surgery

BACKGROUND

Postoperative delirium is a common postsurgical complication in older patients and is associated with high morbidity and mortality. The objective of this study was to determine whether a digital cognitive assessment and patient characteristics could identify those at-risk.

METHODS

Patients 65 years and older undergoing spine surgeries ≥3 h were evaluated as part of a single-center prospective observational cohort study at an academic medical center, from January 1, 2019, to December 31, 2020. Of 220 eligible patients, 161 were enrolled and 152 completed the study. The primary outcome of postoperative delirium was measured by the Confusion Assessment Method for the Intensive Care Unit or the Nursing Delirium Screening Scale, administered by trained nursing staff independent from the study protocol. Baseline cognitive impairment was identified using the tablet-based TabCAT Brain Health Assessment.

RESULTS

Of the 152 patients included in this study, 46% were women. The mean [SD] age was 72 [5.4] years. Baseline cognitive impairment was identified in 38% of participants, and 26% had postoperative delirium. In multivariable analysis, impaired Brain Health Assessment Cognitive Score (OR 2.45; 95% CI, 1.05-5.67; p = 0.037), depression (OR 4.54; 95% CI, 1.73-11.89; p = 0.002), and higher surgical complexity Tier 4 (OR 5.88; 95% CI, 1.55-22.26; p = 0.009) were associated with postoperative delirium. The multivariate model was 72% accurate for predicting postoperative delirium, compared to 45% for the electronic medical record-based risk stratification model currently in use.

CONCLUSION

In this prospective cohort study of spine surgery patients, age, cognitive impairment, depression, and surgical complexity identified patients at high risk for postoperative delirium. Integration of scalable digital assessments into preoperative workflows could identify high-risk patients, automate decision support for timely interventions that can improve patient outcomes and lower hospital costs, and provide a baseline cognitive assessment to monitor for postoperative cognitive change.

Frailty Assessment and Prehabilitation Before Complex Spine Surgery in Patients With Degenerative Spine Disease: A Narrative Review

Degenerative spine disease increases in prevalence and may become debilitating as people age. Complex spine surgery may offer relief but becomes riskier with age. Efforts to lessen the physiological impact of surgery through minimally invasive techniques and enhanced recovery programs mitigate risk only after the decision for surgery. Frailty assessments outperform traditional tools of perioperative risk stratification. The extent of frailty predicts complications after spine surgery such as reoperation for infection and 30-day mortality, as well as elements of social cost such as hospital length of stay and discharge to an advanced care facility. Symptoms of spine disease overlap with phenotypic markers of frailty; therefore, different frailty assessment tools may perform differently in patients with degenerative spine disease. Beyond frailty, however, cognitive decline and psychosocial isolation may interact with frailty and affect achievable surgical outcomes. Prehabilitation, which has reduced perioperative risk in colorectal and cardiac surgery, may benefit potential complex spine surgery patients. Typical prehabilitation includes physical exercise, nutrition supplementation, and behavioral measures that may offer symptomatic relief even in the absence of surgery. Nonetheless, the data on the efficacy of prehabilitation for spine surgery remains sparse and barriers to prehabilitation are poorly defined. This narrative review concludes that a frailty assessment-potentially supplemented by an assessment of cognition and psychosocial resources-should be part of shared decision-making for patients considering complex spine surgery. Such an assessment may suffice to prompt interventions that form a prehabilitation program. Formal prehabilitation programs will require further study to better define their place in complex spine care.

Detection of the Frail Elderly at Risk of Postoperative Sepsis

With the increase in the elderly population, surgery in aged patients is seeing an exponential increase. In this population, sepsis is a major concern for perioperative care, especially in older and frail patients. We aim to investigate the incidence of sepsis in elderly patients receiving diverse types of surgical procedures and explore the predictive capacity of the Hospital Frailty Risk Score (HFRS) to identify patients at high risk of incidence of postoperative sepsis. This study relies on information from the Spanish Minimum Basic Data Set, including data from nearly 300 hospitals in Spain. We extracted records of 254,836 patients aged 76 years and older who underwent a series of surgical interventions within three consecutive years (2016-2018). The HFRS and Elixhauser comorbidity index were computed to determine the independent effect on the incidence of sepsis. Overall, the incidence of postoperative sepsis was 2645 (1.04%). The higher risk of sepsis was in major stomach, esophageal, and duodenal (7.62%), followed by major intestinal procedures (5.65%). Frail patients are at high risk of sepsis. HFRS demonstrated a high predictive capacity to identify patients with a risk of postoperative sepsis and can be a valid instrument for risk stratification and vigilant perioperative monitoring for the early identification of patients at high risk of sepsis.

Surrogate consent for surgery among older adult patients

BACKGROUND

Surrogate consent for surgery is sought when a patient lacks capacity to consent for their own operation. The purpose of this study is to describe older adults who underwent surgical interventions with surrogate consent.

METHODS

A descriptive analysis was performed using data from the American College of Surgeons National Surgical Quality Improvement Program Geriatric Surgery Pilot collected from 2014 to 2018. All patients included were ≥65 years old and underwent a surgical procedure. Demographic and preoperative health characteristics were evaluated to examine differences between those with and without surrogate consent.

RESULTS

In total, 51,618 patients were included in this study, and 6.6% underwent an operation with surrogate consent. Surrogate consent was more common among older patients (median age 83 vs 73, P < .001), female patients (7.7% vs 5.3%, P < .001), patients undergoing emergency as opposed to elective procedures (21.9% vs 1.6%, P < .001), patients with cognitive impairment (50.5% vs 2.4%, P < .001), and patients who were dependent on others for activities of daily living (41.9% vs 4.1%, P < .001). Nearly half of patients with a diagnosis of cognitive impairment signed their own consent.

CONCLUSION

Surrogate consent was more common among patients who were older, female, had a higher comorbidity burden, and had preoperative disability. Nearly half of patients with documented cognitive impairment signed their own consent. These results indicate that further research is needed to understand how surgeons determine which patients require surrogate consent.

External Validation of the American College of Surgeons Surgical Risk Calculator in Elderly Patients Undergoing General Surgery Operations

Preoperative risk stratification in the elderly surgical patient is an essential part of contemporary perioperative care and can be done with the use of the American College of Surgeons Surgical Risk Calculator (ACS-SRC). However, data on the generalizability of the ACS-SRC in the elderly is scarce. In this study, we report an external validation of the ACS-RC in a geriatric cohort. A retrospective analysis of a prospectively maintained database was performed including patients aged > 65 who underwent general surgery procedures during 2012−2017 in a Greek academic centre. The predictive ability of the ACS-SRC for post-operative outcomes was tested with the use of Brier scores, discrimination, and calibration metrics. 471 patients were included in the analysis. 30-day postoperative mortality was 3.2%. Overall, Brier scores were lower than cut-off values for almost all outcomes. Discrimination was good for serious complications (c-statistic: 0.816; 95% CI: 0.762−0.869) and death (c-statistic: 0.824; 95% CI: 0.719−0.929). The Hosmer-Lemeshow test showed good calibration for all outcomes examined. Predicted and observed length of stay (LOS) presented significant differences for emergency and for elective cases. The ACS-SRC demonstrated good predictive performance in our sample and can aid preoperative estimation of multiple outcomes except for the prediction of post-operative LOS.

Potentially Inappropriate Medication Administration Is Associated With Adverse Postoperative Outcomes in Older Surgical Patients: A Retrospective Cohort Study

BACKGROUND

The American Geriatrics Society (AGS) Beers Criteria is an explicit list of potentially inappropriate medications (PIMs) best avoided in adults ≥65 years of age. Cognitively impaired and frail surgical patients often experience poor outcomes after surgery, but the impacts of PIMs on these patients are unclear. Our objective was to assess whether perioperative PIM administration was associated with poor outcomes in geriatric surgical patients. We then evaluated the association between PIM administration and postoperative outcomes in subgroups of patients who were frail or cognitively impaired.

METHODS

We performed a retrospective cohort study of patients ≥65 years of age who underwent elective inpatient surgery at a large academic medical center from February 2018 to January 2020. Edmonton Frail Scale and Mini-Cog screening tools were administered to all patients at their preoperative clinic visit. A Mini-Cog score of 0 to 2 was considered cognitive impairment, and frailty was defined by an Edmonton Frail Scale score of ≥8. Patients were divided into 2 groups depending on whether they received at least 1 PIM (PIM+), based on the 2019 AGS Beers Criteria, in the perioperative period or none (PIM-). We assessed the association of preoperative frailty, cognitive impairment, and perioperative PIM administration with the length of hospital stay and discharge disposition using multiple regression analyses adjusted for age, sex, ASA physical status, and intensive care unit (ICU) admission.

RESULTS

Of the 1627 included patients (mean age, 73.7 years), 69.3% (n = 1128) received at least 1 PIM. A total of 12.7% of patients were frail, and 11.1% of patients were cognitively impaired; 64% of the frail patients and 58% of the cognitively impaired patients received at least 1 PIM. Perioperative PIM administration was associated with longer hospital stay after surgery (PIM-, 3.56 ± 5.2 vs PIM+, 4.93 ± 5.66 days; P < .001; 95% confidence interval [CI], 0.360-0.546). Frail patients who received PIMs had an average length of stay (LOS) that was nearly 2 days longer than frail patients who did not receive PIMs (PIM-, 4.48 ± 5.04 vs PIM+, 6.33 ± 5.89 days; P = .02). Multiple regression analysis revealed no significant association between PIM administration and proportion of patients discharged to a care facility (PIM+, 26.3% vs PIM-, 28.7%; P = .87; 95% CI, -0.046 to 0.054).

CONCLUSIONS

Perioperative PIM administration was common in older surgical patients, including cognitively impaired and frail patients. PIM administration was associated with an increased hospital LOS, particularly in frail patients. There was no association found between PIM administration and discharge disposition.

Preoperative cognition predicts clinical stroke/TIA and mortality after surgical aortic valve replacement in older adults

Stroke and death remain risks of surgical aortic valve replacement (SAVR). Preoperative cognitive screeners repeatedly show that reduced scores predict postoperative outcome, but less is known about comprehensive neuropsychological measures predicting risk. This study had two aims: 1) investigate whether preoperative cognitive measures predicted postoperative clinical stroke/transient ischemic attack (TIA) and mortality in older adults undergoing SAVR, and 2) identify the best predictors within a comprehensive cognitive protocol. A total of 165 participants aged 65 + with moderate-to-severe aortic stenosis completed a comprehensive cognitive test battery preoperatively. Postoperative stroke evaluations were conducted by trained stroke neurologists preoperatively and postoperatively, and mortality outcomes were obtained by report and records. Logistic regressions were conducted to evaluate preoperative cognitive predictors of clinical stroke/TIA within 1 week of surgery and mortality within 1 year of surgery. Multivariate models showed measures of delayed verbal memory recall (OR = 0.86; 95% CI 0.74-0.99) and visuospatial skills (OR = 0.95; 95% CI 0.90-1.01) predicted clinical stroke/TIA within 1 week of surgery, R2 = .41, p < .001, ƒ2 = .69. Measures of naming ability (OR = 0.88; 95% CI 0.80-0.96), verbal memory recall (OR = 1.23; 95% CI 0.99-1.51), visual memory recall (OR = 0.90; 95% CI 0.80-1.00), medical comorbidities (OR = 1.71; 95% CI 1.22-2.65), and sex (OR = 2.39; 95% CI 0.90-7.04) were significant predictors of death within 1 year of surgery, R2 = .68, p < .001, ƒ2 = 2.12. Preoperative cognitive measures reflecting temporal and parietal lobe functions predicted postoperative clinical stroke/TIA within 1 week of SAVR and mortality within 1 year of SAVR. As such, cognitive measures may offer objective and timely indicators of preoperative health, specifically vulnerabilities in cerebral hypoperfusion, which may inform intervention and/or intensive postoperative monitoring and follow-up after SAVR.

Frailty and emergency surgery: identification and evidence-based care for vulnerable older adults

Frailty is a multidimensional state related to accumulation of age- and disease-related deficits across multiple domains. Older people represent the fastest growing segment of the peri-operative population, and 25-50% of older surgical patients live with frailty. When frailty is present before surgery, adjusted rates of morbidity and mortality increase at least two-fold; the odds of delirium and loss of independence are increased more than four- and five-fold, respectively. Care of the older person with frailty presenting for emergency surgery requires individualised and evidence-based care given the high-risk and complex nature of their presentations. Before surgery, frailty should be assessed using a multidimensional frailty instrument (most likely the Clinical Frailty Scale), and all members of the peri-operative team should be aware of each patient's frailty status. When frailty is present, pre-operative care should focus on documenting and communicating individualised risk, considering advanced care directives and engaging shared decision-making when feasible. Shared multidisciplinary care should be initiated. Peri-operatively, analgesia that avoids polypharmacy should be provided, along with delirium prevention strategies and consideration of postoperative care in a monitored environment. After the acute surgical episode, transition out of hospital requires that adequate support be in place, along with clear discharge instructions, and review of new and existing prescription medications. Advanced care directives should be reviewed or initiated in case of readmission. Overall, substantial knowledge gaps about the optimal peri-operative care of older people with frailty must be addressed through robust, patient-oriented research.

Evaluating the Impact of Preoperative Geriatric-Specific Variables and Modified Frailty Index on Postoperative Outcomes After Elective Pancreatic Surgery

BACKGROUND

Pursuing pancreatic resection in elderly patients is often complex and limited by concern for functional status and postoperative risk. This study examines the associations between two different preoperative functional status metrics with postoperative outcomes in the geriatric population.

METHODS

Patients who participated in the ACS NSQIP Geriatric Surgery Research File pilot program (2014-2018) undergoing elective pancreatic operations were included. Two clinically meaningful functional status scores were calculated: the presence of one or more geriatric-specific variable (GSV) and a 5-factor modified frailty index (mFI-5). Multivariable logistic regression adjusting for ACS NSQIP-estimated risk was performed to evaluate associations between preoperative GSV, mFI-5 and 30-day outcome measures.

RESULTS

A total of 1266 patients were included: 808 (64%) age 65-74, 302 (24%) age 75-80, and 156 (12%) age ≥ 81; 843 (67%) patients underwent pancreatoduodenectomy. Operations were performed for pancreatic adenocarcinoma in 712 (56%) patients. Older patients had greater likelihood of postoperative morbidity (35% vs 31% vs 47%, by age group, p = 0.004) and discharge to a facility (12% vs 23% vs 48%, by age group, p < 0.001). Adjusting for ACS NSQIP predicted risk, patients with a preoperative GSV were more likely to require reoperation and discharge to a facility (OR 1.81 [95% CI 1.03-3.16] and 3.95 [95% CI 2.91-5.38], respectively). The mFI-5 was not associated with postoperative outcomes (all p ≥ 0.18).

CONCLUSION

The presence of a preoperative GSV is associated with reoperation and discharge to a skilled facility following elective pancreatic resection. Geriatric-specific variables should be considered in joint preoperative decision making to optimize care.

Advances in the management of peritoneal malignancies

Peritoneal surface malignancies (PSMs) are usually associated with a poor prognosis. Nonetheless, in line with advances in the management of most abdominopelvic metastatic diseases, considerable progress has been made over the past decade. An improved understanding of disease biology has led to the more accurate prediction of neoplasia aggressiveness and the treatment response and has been reflected in the proposal of new classification systems. Achieving complete cytoreductive surgery remains the cornerstone of curative-intent treatment of PSMs. Alongside centralization in expert centres, enabling the delivery of multimodal and multidisciplinary strategies, preoperative management is a crucial step in order to select patients who are most likely to benefit from surgery. Depending on the specific PSM, the role of intraperitoneal chemotherapy and of perioperative systemic chemotherapy, in particular, in the neoadjuvant setting, is established in certain scenarios but questioned in several others, although more prospective data are required. In this Review, we describe advances in all aspects of the management of PSMs including disease biology, assessment and improvement of disease resectability, perioperative management, systemic therapy and pre-emptive management, and we speculate on future research directions.

Association of propofol induction dose and severe pre-incision hypotension among surgical patients over age 65

STUDY OBJECTIVE

We aimed to study the association between propofol induction dose (mg/kg) and pre-incision severe hypotension (Mean Arterial Pressure (MAP) ≤ 55 mmHg) among patients ≥65 years of age.

DESIGN

Retrospective Observational.

SETTING

40 centers participating in the Multicenter Perioperative Outcomes Group consortium.

PATIENTS

Patients ≥65 years of age undergoing non-cardiac, non-vascular surgery who received propofol for general anesthetic induction prior to endotracheal intubation between January 2014 and December 2018.

INTERVENTIONS

None.

MEASUREMENTS

The primary exposure was total propofol induction dose in mg/kg, and the primary outcome was occurrence of severe hypotension (MAP≤55 mmHg) prior to surgical incision, stratified by non-invasive vs. invasive blood pressure monitoring type.

MAIN RESULTS

Among 320,585 total patients, 22.6% experienced the outcome of pre-incision severe hypotension (MAP≤55 mmHg). When stratified by blood pressure monitoring type, 20.7% with non-invasive blood pressure measurements, and 35.0% with invasive blood pressure measurements had the outcome. After controlling for a variety of patient and procedural factors, there was a significant independent association between propofol induction dose and pre-incision hypotension (Non-invasive blood pressure cohort odds ratio (OR) 1.10; 95% confidence interval (CI) 1.07 to 1.13; p < 0.001; and Invasive blood pressure cohort OR 1.15; 95%CI 1.10 to 1.21; adjusted p < 0.001). The association was robust to alternative definitions of the outcome, including less severe hypotension (MAP≤65 mmHg) and blood pressure drop from baseline as a continuous measure. Although no threshold safe induction dose was identified at which hypotension was avoided, an analysis of propofol dose greater or less than 1.5 mg/kg (i.e. the maximum FDA-defined typical induction dose) demonstrated that doses in excess of the FDAs threshold were positively associated with odds of severe hypotension (Non-invasive cohort: OR 1.05; 95% CI 1.02 to 1.08; p < 0.001; Invasive cohort: OR 1.11; 95%CI 1.05 to 1.17; adjusted p < 0.001).

CONCLUSIONS

In a multicenter cohort of geriatric surgical patients receiving propofol for general anesthetic induction and endotracheal intubation, severe pre-incision hypotension (MAP ≤55 mmHg) that has previously been associated with postoperative morbidity was common. The dose of propofol used was significantly associated with increased odds of this outcome after controlling for a number of clinically relevant factors. Future studies that are designed to test different approaches to anesthesia induction for reducing severe post induction pre-incision hypotension are warranted.

Efficacy of geriatric multidisciplinary oncology clinic in the surgical treatment decision-making process for frail elderly patients with colorectal cancer

Purpose

Multidisciplinary care has become a cornerstone of colorectal cancer management. To evaluate the clinical efficacy of a geriatric multidisciplinary oncology clinic (GMOC), we analyzed the surgical treatment decision-making process and outcomes.

Methods

This retrospective single-center study reviewed the data of patients aged ≥65 years who participated in the GMOC at a tertiary referral hospital between 2015 and 2021. The clinical adherence rate, comprehensive geriatric assessment, and a multidimensional frailty score (MFS) were obtained. The groups that were recommended and not recommended for surgery were compared, analyzing the factors impacting the decision and 1-year survival outcomes. Furthermore, the postoperative complications of patients who underwent surgery were evaluated.

Results

A total of 165 patients visited the GMOC, and 74 had colorectal cancer (mean age, 85.5 years [range, 81.2–89.0 years]). Among patients with systemic disease (n = 31), 7 were recommended for surgery, and 5 underwent surgery. Among patients with locoregional disease (n = 43), 18 were recommended for surgery, and 12 underwent surgery. Patients recommended and not recommended for surgery had significantly different activities of daily living (ADL) (P = 0.024), instrumental ADL (P = 0.001), Mini-Mental State Examination (P = 0.014), delirium risk (P = 0.039), and MFS (P = 0.001). There was no difference in the 1-year overall survival between the 2 groups (P = 0.980). Of the 17 patients who underwent surgery, the median (interquartile range) of operation time was 165.0 minutes (120.0–270.0 minutes); hospital stay, 7.0 days (6.0–8.0 days); and 3 patients had wound complications.

Conclusion

Proper counseling of patients through the GMOC could lead to appropriate management and favorable outcomes.

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.

Thoracic surgery with geriatric assessment and collaboration can prepare frail older adults for lung cancer surgery

BACKGROUND AND OBJECTIVES

We assessed frailty, measured by a comprehensive geriatric assessment-based frailty index (FI-CGA), and its association with postoperative outcomes among older thoracic surgical patients.

METHODS

Patients aged ≥65 years evaluated in the geriatric-thoracic clinic between June 2016 through May 2020 who underwent lung surgery were included. Frailty was defined as FI-CGA > 0.2, and "occult frailty", a level not often recognized by surgical teams, as 0.2 < FI-CGA < 0.4. A qualitative analysis of geriatric interventions was performed.

RESULTS

Seventy-three patients were included, of which 45 (62%) were nonfrail and 28 (38%) were frail. "Occult frailty" was present in 23/28 (82%). Sixty-one (84%) had lung malignancy. Geriatric interventions included delirium management, geriatric-specific pain and bowel regimens, and frailty optimization. More sublobar resections versus lobectomies (61% vs. 25%) were performed among frail patients. Frailty was not significantly associated with overall complications (odds ratio [OR]: 2.4; 95% confidence interval [CI]: 0.88-6.44; p = 0.087), major complications (OR: 2.33; 95% CI: 0.48-12.69; p = 0.293), discharge disposition (OR: 2.8; 95% CI: 0.71-11.95; p = 0.141), or longer hospital stay (1.3 more days; p = 0.18).

CONCLUSION

Frailty and "occult frailty" are prevalent in patients undergoing lung surgery. However, with integrated geriatric management, these patients can safely undergo surgery.

Edmonton frailty scale score predicts postoperative delirium: a retrospective cohort analysis

BACKGROUND

Frailty has been associated with postoperative delirium (POD). Studies suggest that the Fried phenotype has a stronger association with POD than the Edmonton Frailty Scale (EFS) criteria. Although phenotypic frailty is recognized as a good predictor of delirium, the EFS has higher ratings for feasibility in the surgical setting. Thus, our aim was to determine the association between EFS-assessed vulnerability and POD in an elective surgical population of older adults. A secondary aim was to determine which domains assessed by the EFS were closely associated with POD.

METHODS

After IRB approval was received, electronic medical records of surgical patients at our institution were downloaded from 12/1/2018 to 3/1/2020. Inclusion criteria included age ≥ 65 years, preoperative EFS assessment within 6 months of surgery, elective surgery not scheduled for intensive care unit (ICU) stay but followed by at least 1 day postoperative stay, and at least two in-hospital evaluations with the 4 A's test (arousal, attention, abbreviated mental test-4, acute change [4AT]) on the surgical ward. Vulnerability was determined by EFS score ≥ 6. Patients were stratified into two groups according to highest postoperative 4AT score: 0-3 (no POD) and ≥ 4 (POD). Odds of POD associated with EFS score ≥ 6 were evaluated by using logistic regression adjusted for potential confounders.

RESULTS

The dataset included 324 patients. Vulnerability was associated with higher incidence of POD (p = 0.0007, Fisher's exact). EFS ≥6 was consistently associated with POD in all bivariate models. Vulnerability predicted POD in multivariable modeling (OR = 3.5, 95% CI 1.1 to 11.5). Multivariable analysis of EFS domains revealed an overall trend in which higher scores per domain had a higher odds for POD. The strongest association occurred with presence of incontinence (OR = 3.8, 95% CI 1.2 to 11.0).

CONCLUSIONS

EFS criteria for vulnerability predict POD in older, non-ICU patients undergoing elective surgery.

Exploring Cost-Effectiveness of the Comprehensive Geriatric Assessment in Geriatric Oncology: A Narrative Review

Simple Summary

The Comprehensive Geriatric Assessment is a multidimensional and multidisciplinary evaluation designed for elderly patients with the goal of structuring tailored care and follow-up. Despite the known benefits of this approach, the Comprehensive Geriatric Assessment is not universally applied to elderly cancer patients due to economic and practical barriers. This narrative review aims to investigate the cost-effectiveness of the Comprehensive Geriatric Assessment adopted in geriatric oncology. The results revealed a lack of research on the topic, but recurrent cost-saving effects of this approach in geriatric oncology settings were highlighted—suggesting a positive cost-effectiveness ratio. Further structured research with comprehensive economic evaluations is needed to confirm these findings.

Abstract

The Comprehensive Geriatric Assessment (CGA) and the corresponding geriatric interventions are beneficial for community-dwelling older persons in terms of reduced mortality, disability, institutionalisation and healthcare utilisation. However, the value of CGA in the management of older cancer patients both in terms of clinical outcomes and in cost-effectiveness remains to be fully established, and CGA is still far from being routinely implemented in geriatric oncology. This narrative review aims to analyse the available evidence on the cost-effectiveness of CGA adopted in geriatric oncology, identify the relevant parameters used in the literature and provide recommendations for future research. The review was conducted using the PubMed and Cochrane databases, covering published studies without selection by the publication year. The extracted data were categorised according to the study design, participants and measures of cost-effectiveness, and the results are summarised to state the levels of evidence. The review conforms to the SANRA guidelines for quality assessment. Twenty-nine studies out of the thirty-seven assessed for eligibility met the inclusion criteria. Although there is a large heterogeneity, the overall evidence is consistent with the measurable benefits of CGA in terms of reducing the in-hospital length of stay and treatment toxicity, leaning toward a positive cost-effectiveness of the interventions and supporting CGA implementation in geriatric oncology clinical practice. More research employing full economic evaluations is needed to confirm this evidence and should focus on CGA implications both from patient-centred and healthcare system perspectives.

Application of Care Bundles in Postanesthesia Recovery for Elderly Patients with Colorectal Cancer

Objective

Based on the postanesthesia recovery procedure for elderly patients with colorectal cancer, a care bundle program was conducted to validate its effectiveness.

Method

According to the characteristics of elderly patients with colorectal cancer, five measures including respiratory management, circulatory stability, pain assessment, body temperature monitoring, and internal environment stability were integrated into one bundle. Postanesthesia care unit (PACU) care bundle program for elderly patients was developed and used to improve recovery care. The monitoring data of the pre-PACB group given care bundles were collected and compared with the data of the post-PACB group who were given conventional recovery care.

Result

222 patients in post-PACB group had shorter intubation time than 291 patients in pre-PACB group (37.7 ± 24.4 min vs. 42.1 ± 23.3 min, P < 0.05). The length of stay in PACU was longer in pre-PACB group (89.9 ± 33.5 min vs. 81.6 ± 31.1 min, P < 0.05). More adverse events were found in the post-PACB group than in the pre-PACB group (72.1% vs. 34.0%).

Conclusion

After general anesthesia of patients with colorectal cancer, the application of the care bundles can improve the quality of recovery, shorten the intubation time and the length of stay in PACU, and reduce the complications caused by anesthesia.

Anaesthetic Approach to Enhanced Recovery after Surgery for Kidney Transplantation: A Narrative Review

Enhanced recovery after surgery (ERAS) protocols are designed to reduce medical complications, the length of hospital stays (LoS), and healthcare costs. ERAS is considered safe and effective for kidney transplant (KTx) surgery. KTx recipients are often frail with multiple comorbidities. As these patients follow an extensive diagnostic pathway preoperatively, the ERAS protocol can ideally be implemented at this stage. Small singular changes in a long perioperative pathway can result in significant positive outcomes. We have investigated the current evidence for an ERAS pathway related to anaesthetic considerations in renal transplant surgery for adult recipients.

Safety Evaluation of Cervical Dorsal Instrumentation in Geriatric Patients: Experience at a Level 1 Center for Spinal Surgery-A Single Center Cohort Study

Objective

Dorsal instrumentation of the cervical spine is an established treatment in spine surgery. However, careful planning is required, particularly in elderly patients. This study evaluates early clinical outcomes in geriatric patients undergoing complex spine surgery.

Methods

In this retrospective, single center cohort study, we included all geriatric patients (aged ≥65 years) who underwent dorsal instrumentation between January 2013 and December 2020. We analyzed postoperative complications and the 30-day in-hospital mortality rate. Furthermore, the Charlson comorbidity index (CCI) and Clavien-Dindo grading system (CDG) were used to assess the patients' comorbidity burden.

Results

In total, 153 patients were identified and included. The mean age of patients was 78 years (SD ± 7). Traumatic injury (53.6%) was the most common reason for surgery. 60.8% of the patients underwent dorsal instrumentation with 3 or more levels. The most common comorbidities were arterial hypertension (64%), diabetes mellitus (22.2%), coronary heart disease and atrial fibrillation (19.6%). The most common adverse event (AE) was pneumonia (4%) and the most common surgery-related complication was wound infection (5.2%). Among patients categorized as high risk for AE (CCI > 5), 14.6% suffered a postoperative AE. In our univariate analysis, we found no risk factors for high rates of complications or mortality.

Conclusion

Our data demonstrates that older patients were at no significant risk of postoperative complications. The CCI/CDG scores may identify patients at higher risk for adverse events after dorsal instrumentation, and these assessments should become an essential component of stratification in this older patient population.

Perioperative Brain Health in the Older Adult: A Patient Safety Imperative

While people 65 years of age and older represent 16% of the population in the United States, they account for >40% of surgical procedures performed each year. Maintaining brain health after anesthesia and surgery is not only important to our patients, but it is also an increasingly important patient safety imperative for the specialty of anesthesiology. Aging is a complex process that diminishes the reserve of every organ system and often results in a patient who is vulnerable to the stress of surgery. The brain is no exception, and many older patients present with preoperative cognitive impairment that is undiagnosed. As we age, a number of changes occur in the human brain, resulting in a patient who is less resilient to perioperative stress, making older adults more susceptible to the phenotypic expression of perioperative neurocognitive disorders. This review summarizes the current scientific and clinical understanding of perioperative neurocognitive disorders and recommends patient-centered, age-focused interventions that can better mitigate risk, prevent harm, and improve outcomes for our patients. Finally, it discusses the emerging topic of sleep and cognitive health and other future frontiers of scientific inquiry that might inform clinical best practices.

Comparison of Electronic Frailty Metrics for Prediction of Adverse Outcomes of Abdominal Surgery

Importance

Electronic frailty metrics have been developed for automated frailty assessment and include the Hospital Frailty Risk Score (HFRS), the Electronic Frailty Index (eFI), the 5-Factor Modified Frailty Index (mFI-5), and the Risk Analysis Index (RAI). Despite substantial differences in their construction, these 4 electronic frailty metrics have not been rigorously compared within a surgical population.

Objective

To characterize the associations between 4 electronic frailty metrics and to measure their predictive value for adverse surgical outcomes.

Design, Setting, and Participants

This retrospective cohort study used electronic health record data from patients who underwent abdominal surgery from January 1, 2010, to December 31, 2020, at 20 medical centers within Kaiser Permanente Northern California (KPNC). Participants included adults older than 50 years who underwent abdominal surgical procedures at KPNC from 2010 to 2020 that were sampled for reporting to the National Surgical Quality Improvement Program.

Main Outcomes and Measures

Pearson correlation coefficients between electronic frailty metrics and area under the receiver operating characteristic curve (AUROC) of univariate models and multivariate preoperative risk models for 30-day mortality, readmission, and morbidity, which was defined as a composite of mortality and major postoperative complications.

Results

Within the cohort of 37 186 patients, mean (SD) age, 67.9 (female, 19 127 [51.4%]), correlations between pairs of metrics ranged from 0.19 (95% CI, 0.18- 0.20) for mFI-5 and RAI 0.69 (95% CI, 0.68-0.70). Only 1085 of 37 186 (2.9%) were classified as frail based on all 4 metrics. In univariate models for morbidity, HFRS demonstrated higher predictive discrimination (AUROC, 0.71; 95% CI, 0.70-0.72) than eFI (AUROC, 0.64; 95% CI, 0.63-0.65), mFI-5 (AUROC, 0.58; 95% CI, 0.57-0.59), and RAI (AUROC, 0.57; 95% CI, 0.57-0.58). The predictive discrimination of multivariate models with age, sex, comorbidity burden, and procedure characteristics for all 3 adverse surgical outcomes improved by including HFRS into the models.

Conclusions and Relevance

In this cohort study, the 4 electronic frailty metrics demonstrated heterogeneous correlation and classified distinct groups of surgical patients as frail. However, HFRS demonstrated the highest predictive value for adverse surgical outcomes.

Evidence-Based Guideline on Management of Postoperative Delirium in Older People for Low Resource Setting: Systematic Review Article

Background

Postoperative delirium is the highest prevalence and life-threatening complication following geriatric surgery. The overall incidence rate varies from 5% to 52% of hospitalized surgical patients based on the type of surgery that often began in the postanesthesia care unit and continues up to 5 days post-surgery. Postoperative delirium manifests as a hypoactive, hyperactive and mixed subtype. The mechanism of delirium development is not clear, but it is accepted that delirium is a result of the patient's underlying vulnerabilities or risk factors combined with an outside stressor such as infection or surgery.

Objective

To develop evidence-based recommendations for the prevention, diagnosis, and treatment of postoperative delirium.

Methods

Literature was searched from PubMed, CINAH, Google Scholar, and Cochrane databases that are published from 2010 to 2021 by formulating inclusion and exclusion criteria. Filtering was made depending on methodological quality, outcome, and data on population. Finally, 11 meta-analysis, 11 systematic reviews, 7 interventional studies, 11 observational studies, and recommendations of the previous clinical practice guideline developed by the American and European are included in this review.

Results

A total of 43 studies were considered in this evaluation. The development of this guideline was based on nine studies on risk stratification for postoperative delirium, eighteen studies on risk minimization and prevention for postoperative delirium, five studies on diagnosis for postoperative delirium, and eleven studies on treatments for postoperative delirium.

Conclusion

Postoperative delirium management can be categorized into risk assessment, risk minimization, early diagnosis, and treatment. Early diagnosis is critical to trigger focused and effective treatment. Non-pharmacological interventions are the first-line management for both hypoactive and hyperactive postoperative with considering contributory factors and underlying causes. Antipsychotics should only be used for hyperactive delirium individuals who try to harm themselves. Current evidence suggested that dexmedetomidine can be used as a treatment option for postoperative delirium.

Application of a perioperative nursing strategy in the surgical treatment of elderly patients: a narrative review†

With the steady increase of older people in society, a progressively greater number of patients belonging to the geriatric group need surgical treatment. Since elderly patients with reduced physiological reserve and organ failure often have chronic diseases, geriatric syndrome, and other clinical problems, the perioperative nursing of elderly patients is more complicated. Therefore, we need to comprehensively consider clinical issues, such as patients’ preoperative status, surgical risks, and postoperative quality of life and life expectancy, and conduct comprehensive evaluations and holistic, individualized, and continuous nursing and therapy through the participation of interdisciplinary teams to achieve better curative effects. Here, the perioperative nursing of elderly patients is reviewed, including preoperative evaluation and nursing, intraoperative management, and postoperative nursing.

Preoperative Advance Care Planning for Older Adults Undergoing Major Abdominal Surgery

BACKGROUND

Advance care planning (ACP) is recommended for older patients undergoing surgery. ACP consists of creating advance directives (ADs), identifying surrogate decision makers (SDMs), and documenting goals of care. We identified factors associated with documentation of preoperative ACP to identify opportunities to optimize ACP for older surgical patients.

METHODS

This was a retrospective study of surgical patients ≥70 years old who underwent elective, high-risk abdominal procedures between 01/2015-08/2019. Clinical data were obtained from our institution's National Surgical Quality Improvement Project database. ACP metrics were extracted from the electronic medical record. We analyzed the data to identify patient factors associated with ACP metrics. We also analyzed whether ACP was more frequent for patients who experienced postoperative complications or death.

RESULTS

267/1,651 patients were included. 97 patients (36%) had an AD available on the day of surgery, 57 (21%) had an SDM identified, and 31 (12%) had a documented goals of care conversation. On multivariable analysis, older age and white race were associated with an increased likelihood of having an AD available on the day of surgery. Women were 1.7 times more likely to have an SDM (p = 0.02). No patient or surgeon factors were significantly associated with goals of care documentation. ACP was not performed more frequently in patients who experienced postoperative complications or death.

CONCLUSION

In this series, ACP was not routinely documented for older patients undergoing major surgery. ACP was not more frequent in patients who experienced complications or death, demonstrating the importance of universal preoperative ACP in older patients.

Frailty and perioperative patient-reported disability in patients undergoing cardiac surgery: a pilot study

Background

Results

Conclusions

An audit of perioperative end-of-life care practices and documentation relating to patients who died in a surgical unit in three Victorian hospitals

The number of older, frail patients undergoing surgery is increasing, prompting consideration of the benefits of intensive treatment. Despite collaborative decision-making processes such as advance care planning being supported by recent Australian legislation, their role in perioperative care is yet to be defined. Furthermore, there has been little evaluation of the quality of end-of-life care in the surgical population. We investigated documentation of the premorbid functional status, severity of illness, intensity of treatment, operative management and quality of end-of-life care in patients who died in a surgical unit, with a retrospective study of surgical mortality which was performed across three hospitals over a 23-month period in Victoria, Australia. Among 99 deceased patients in the study cohort, 68 had a surgical operation. Preoperative functional risk assessment by medical staff was infrequently documented in the medical notes (5%) compared with activities of daily living (69%) documented by nursing staff. Documented preoperative discussions regarding the risk of death were rarely and inconsistently done, but when done were extensive. Documented end-of-life care discussions were identified in 71%, but were frequently brief, inconsistent, and in 60% did not occur until 48 hours from death. In 35.4% of instances, documented discussions involved junior staff (registrars or residents), and 43.4% involved intensive care unit staff. Palliative or terminal care referrals also occurred late (1-2 days prior to death). Not-for-resuscitation orders were frequently changed when approaching the end of life. Overall, 57% of deceased patients had a documented opportunity for farewell with family. We conclude that discussions and documentation of end-of-life care practices could be improved and recommend that all surgical units undertake similar audits to ensure that end-of-life care discussions occur for high-risk and palliative care surgical patients and are documented appropriately.
