The Perioperative Care of Older Patients

Effects of an Integrated Geriatric-Orthopedic Co-management (InGerO) on the Treatment of Older Orthopedic Patients with Native and Periprosthetic Joint Infections

In view of our aging society, co-management with a geriatrician is becoming increasingly important. While such collaborations have been working successfully in trauma surgery for years, it is still unclear whether they are also helpful for non-trauma patients in orthopedics. The aim of this study was to investigate the effect of such a cooperation in orthopedic non-trauma patients with native and periprosthetic joint infections on the basis of five key areas.A retrospective observational study as a before and after comparison was used to compare routine data from patients with and without orthogeriatric co-management after nontraumatic surgery. Eligible patients for the study were 70 years and older, had a diagnosis of hip, knee, or shoulder infection, and had been hospitalized for at least 14 days. Co-management consisted of close follow-up by a geriatrician, Comprehensive Geriatric Assessment, and "complex early geriatric rehabilitation". The comparison group received therapy as usual, without a geriatrician and without "complex early geriatric rehabilitation". Special attention was paid to delirium, pain, mobility, postoperative complications, and renal function.Analysis was carried out with 59 patients "with" and 63 "without" geriatric co-management. In the co-management group, delirium was detected significantly more often (p < 0.001), significantly lower pain intensities were measured at the time of discharge (p < 0.001), transfer ability had clearly improved more (p = 0.04), and renal function was more frequently noted (p = 0.04). No significant differences were found with respect to principal diagnoses, surgical procedures performed, complication rates, pressure ulcer and delirium incidence, operative revisions, or length of inpatient stay.Orthogeriatric co-management in orthopedic patients with native and periprosthetic joint infections and nontraumatic surgery appears to have positive impacts on recognition and treatment of delirium, pain management, transfer performance, and attention to renal function. Further studies should follow in order to conclusively assess the value of such co-management in orthopedic nontraumatic surgery patients.

"Eat Enough"-A nurse-led intervention to enhance hospitalized older adults' protein and energy nutrition

PURPOSE

To develop an intervention enhancing hospitalized older adults' nutrition.

METHODS

For the first time, a mixed-methods design with data triangulation was applied according to the six-step model of Corry et al. to elaborate on a complex nursing intervention in the form of a logic model. Patients who were aged ≥80 years and hospitalized for at least 5 days were included. Sample size for quantitative practice analysis was 135 older adults, whereas 22 older inpatients participated in interviews and observations for needs analysis and generated data for key principles.

FINDINGS

The intervention "Eat Enough" encompasses nursing team culture and comprises six actionable targets to deliver needs-based support and reach required protein and energy intake for hospitalized older adults by sensitizing nurses and the interprofessional team. Facilitating nutritional intake would be supported by an advanced practice nurse who considers the medical and nursing care plan and therapy.

CONCLUSIONS

The intervention "Eat Enough" demonstrates that nurses play a key role in interprofessional teams to enhance older adults' nutrition in hospital. The pipeline model displays how the actionable targets can be achieved, and how awareness raising can influence the context-leading to raised calories and protein requirement coverages and shorter length of stay.

IMPLICATIONS FOR CLINICAL PRACTICE

By identifying risk factors of malnutrition and strengthening nurses' responsibilities, the intervention "Eat Enough" could significantly enhance nutrition among hospitalized older adults. However, the logic model should be tested and implemented in future research.

Nutritional care in patients undergoing laparoscopic/minimally invasive surgeries for gastrointestinal tumours

The introduction of minimally invasive surgeries for gastrointestinal tumours has been associated with many favourable postoperative outcomes and a reduced impact on nutritional status. The literature review begins by discussing the impact of minimally invasive procedures on the nutritional status of patients with gastrointestinal tumours, followed by indications for enteral nutrition (EN) in this population, including preoperative nutritional support and postoperative nutritional support. The review then examines the evidence that favours the use of EN in this population, including studies demonstrating improved outcomes with preoperative EN and reduced postoperative complications with postoperative EN. It also discusses potential strategies for improving outcomes with EN, such as early initiation of feeding and individualized nutrition plans. Overall, current evidence shows that EN improves outcomes, reduces complications, and enhances the quality of life. However, the optimal timing, composition of EN, and long-term outcomes are still unclear, indicating the need for future investigations.

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.

[Are we missing the first step? : An online expert survey in a mixed methods design on current state analysis of perioperative risk estimation and preoperative preparation of patients over 65 years old in Germany]

BACKGROUND

The proportion of patients over 65 years of age in surgical care is increasing in Germany. Frailty represents a relevant problem in the perioperative care of older patients and has a negative impact on the postoperative outcome. The individual degree of frailty can be influenced. Multimodal prehabilitation concepts can contribute to improving the degree of frailty in the perioperative care of affected patients. As a multidimensional syndrome, frailty is related to the aging process, affects multiple organ systems and typically leads to increased vulnerability to internal and external stressors. This is accompanied by a decrease in homeostatic reserves and resilience, which implies an increased risk of several adverse health outcomes, such as loss of physical function and quality of life. Prehabilitation is described as a multimodal concept to prepare patients preoperatively in the best possible way for elective surgical procedures, thereby minimizing postoperative complications and improving the patients' outcome.

METHOD

Current state analysis of perioperative care of patients over the age of 65 years in relation to frailty assessment and the use of prehabilitation concepts. Conducting a multicenter online survey of anesthesiology experts (n = 189) in German anesthesiology departments. Survey of the preoperative preparation and assessment routine in patients aged 65 years and over using a mixed methods design questionnaire.

OBJECTIVE

The aim of this study was to demonstrate the applied assessments and measures taken for specific perioperative risk assessment and preoperative preparation of patients aged 65 years and over.

RESULTS

Specific risk assessments or additional preoperative preparation of patients older than 65 years are currently not carried out routinely. The preoperative risk assessment and preparation usually focus on ascertaining the patient's previous illnesses or diseases. Assessment instruments for assessing frailty and multimodal prehabilitation concepts are not used in clinical practice in a noteworthy quantity.

CONCLUSION

In German clinical practice frailty assessment and structured prehabilitation approaches in perioperative care of older patients are not broadly known or established. Multimodal prehabilitation concepts can positively influence the outcome of older patients. To this end, it should be considered good clinical practice to assess and address frailty in older patients and to establish multimodal prehabilitation approaches tailored to this patient group.

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.

Postoperative Nutrition Management: Who Needs What?

Background

Early oral feeding after major abdominal surgery has been clearly shown to be safe and not a risk factor for anastomotic dehiscence. Within the Enhanced Recovery after Surgery protocol, it is the nutritional plan A. Nonetheless, one must consider that postoperative protein and energy requirements will often be not covered by oral food intake alone. Because nutritional status has been shown to be a prognostic factor in patients undergoing major abdominal surgery, the preoperative identification of patients at risk may be mandatory. Malnutrition may be underestimated in an overweight society. With special regard to patients with cancer and those with preexisting malnutrition, an accumulating caloric gap may be harmful in the early and late postoperative periods. Furthermore, complications requiring reoperation and intensive care treatment may occur.

Summary

Therefore, a plan B for postoperative nutrition therapy is needed, using preferentially the enteral route. The European Society for Clinical Nutrition and Metabolism recently addressed perioperative nutritional management and the indications for enteral and even parenteral supplementation to achieve caloric requirements in the postoperative course. In the first months after surgery, persisting weight loss is common in patients with upper gastrointestinal resections, even in those with an uncomplicated course. This may delay the initiation of adjuvant chemotherapy, increase toxicity, and worsen long-term outcomes.

Geriatric assessment and medical preoperative screening (GrAMPS) program for older hernia patients

PURPOSE

The incidence of older adults undergoing inguinal and ventral hernia repairs is increasing. Older adults are disproportionately affected by age-related risk factors, which are often under-recognized and may adversely affect surgical outcomes. These age-related risk factors often termed "geriatric syndromes," include multimorbidity, frailty, cognitive impairment, depression, obesity, functional impairment, polypharmacy, and poor subjective health. The aim of this study was to identify the prevalence of age-related risk factors in older patients undergoing elective hernia repair.

METHODS

Patients aged 60 years or older with a planned elective surgical repair of a ventral or inguinal hernia were prospectively enrolled in a clinic. Subjects completed several validated screening tools for geriatric syndromes.

RESULTS

Seventy patients completed preoperative assessments (mean age: 68.5 years). In total, 24 (34.3%) screened positive for previously unrecognized objective cognitive impairment (Mini-Cog) and 33 (47.1%) for a subjective memory concern. Sixty patients (85.7%) met criteria for polypharmacy. Additionally, 48 (68.6%) screened positive for either pre-frailty (37, 52.9%) or frailty (11, 15.7%), and 66 (94.3%) had multimorbidity. Twenty-five (35.7%) patients self-rated their health as "poor" or "fair," and 18 (25.7%) patients endorsed some functional impairment.

CONCLUSIONS

There is a high prevalence of age-related risk factors in older patients undergoing elective hernia repair. Further, these factors are often unrecognized and underappreciated despite their potential to significantly impact informed consent and shared decision making. Additional study is required to define the impact of these age-related risk factors on surgical outcomes, which will inform preoperative risk assessment and optimization through modifiable risk reduction.

[Postoperative multiprofessional comprehensive treatment]

BACKGROUND

In orthogeriatric centers, postoperative, multiprofessional comprehensive treatment has proven to be an effective component in the convalescence of geriatric patients. The aim of the treatment is to minimize the perioperative risk and safely achieve individual rehabilitation goals in the acute inpatient stay. To meet the needs of geriatric patients, in addition to changes in the spatial division and design, primarily adjustments to the team composition and the procedural processes are required.

THERAPEUTIC STRATEGIES

An interdisciplinary and multiprofessional team (orthopedics/traumatology, geriatrics, nursing, physiotherapy, occupational therapy, social services, psychology, speech therapy, …) uses geriatric assessments in regular team meetings to collect and analyze the current rehabilitation status of patients; ICF-based goals are formulated and the therapy is adapted to individual needs. Here, too, the focus is on recording the individual risk (comorbidities, mental status, polypharmacy, malnutrition, fragility) and avoiding preventable complications. Multiprofessional strategies for avoiding or treating postoperative delirium are particularly important. In addition, maintaining patients' autonomy is the top priority, so that they can be released from the acute inpatient stay strengthened for follow-up treatment or their home environment. The establishment of orthogeriatric comanagement in acute inpatient facilities is an important component in the process chain, from which many geriatric patients benefit in the context of postoperative recovery.

In-Hospital Clinical Outcomes in Patients with Fragility Fractures of the Lumbar Spine, Thoracic Spine, and Pelvic Ring: A Comparison of Data before and after Certification as a DGU® Geriatric Trauma Centre

Background and Objectives: The implementation of orthogeriatric co-management (OGCM) reflects the demand for interdisciplinary collaborations due to the increasing comorbidities of geriatric trauma patients. This study aimed to assess clinical in-hospital outcomes in lumbar spine, thoracic spine, and pelvic ring fragility fracture patients before and after the implementation of a Geriatric Trauma Centre (GTC) certified by the German Trauma Society (DGU^®). Materials and Methods: In this observational, retrospective cohort study, geriatric trauma patients (>70 years of age) were stratified into either a pre-GTC group (hospital admission between 1 January 2012 and 31 December 2013) or a post-GTC group (hospital admission between 1 January 2017 and 31 December 2018). Patients’ pre-injury medical complexity was measured by ASA class (American Society of Anaesthesiologists classification), the use of anticoagulant medication, and the ACCI (Age-adjusted Charlson Comorbidity Index). Outcome parameters were patients’ in-hospital length of stay (LOS) and mortality rates, as well as new in-hospital findings and diagnoses. Further, the necessity of deviation from initial management plans due to complications was assessed using the Adapted Clavien–Dindo Scoring System in Trauma (ACDiT score of ≥1). Results: Patients in the post-GTC group (n = 111) were older (median age 82.0 years) compared to the pre-GTC group (n = 108, median age 80.0 years, p = 0.016). No differences were found in sex, body mass index, ASA class, or ACCI (all p > 0.05). Patients in the post-GTC group used vitamin K antagonists or direct oral anticoagulants more frequently (21.3% versus 10.8%). The incidence of non-surgical treatment and mortality was comparable between groups, while LOS tended to be shorter in the post-GTC group (7.0 days versus 9.0 days, p = 0.076). In the post-GTC group, the detection of urinary tract infections (UTI) increased (35.2% versus 16.2%, p = 0.001), and the delirium diagnoses tended to increase (13.0% versus 6.3%, p = 0.094), while an ACDiT score of ≥1 was comparable between groups (p = 0.169). Conclusions: In this study including lumbar spine, thoracic spine, and pelvic ring geriatric fragility fractures, patients in the post-GTC group were more medically complex. More UTIs and the tendency for increased delirium detection was observed in the post-GTC group, likely due to improved diagnostic testing. Nonetheless, the necessity of deviation from initial management plans (ACDiT score of ≥1) was comparable between groups, potentially a positive result of OGCM.

Age-Related Risk Factors in Ventral Hernia Repairs: A Review and Call to Action

BACKGROUND

As the population ages, the incidence of ventral hernias in older adults is increasing. Ventral hernia repairs (VHR) should not be considered low risk operations, particularly in older adults who are disproportionately affected by multiple age-related factors that can complicate surgery and adversely affect outcomes. Although age-related risk factors have been well established in other surgical fields, there is currently little data describing their impact on VHR.

METHODS

We performed a systematic review of the literature to identify studies that examine the effects of age-related risk factors on VHR outcomes. This was conducted using Cochrane Library, Embase, PubMed (Medline), and Google Scholar databases, all updated through June 2020. We selected relevant studies using the keywords, multimorbidity, comorbidities, polypharmacy, functional dependence, functional status, frailty, cognitive impairment, dementia, sarcopenia, and malnutrition. Primary outcomes include mortality and overall complications following VHR.

RESULTS

We summarize the evidence basis for the significance of age-related risk factors in elective surgery and discuss how these factors increase the risk of adverse outcomes following VHR. In particular, we explore the impact of the following risk factors: multimorbidity, polypharmacy, functional dependence, frailty, cognitive impairment, sarcopenia, and malnutrition. As opposed to chronological age itself, age-related risk factors are more clinically relevant in determining VHR outcomes.

CONCLUSIONS

Given the increasing complexity of VHR, addressing age-related risk factors pre-operatively has the potential to improve surgical outcomes in older adults. Preoperative risk assessment and individualized prehabilitation programs aimed at improving patient-centered outcomes may be particularly useful in this population.

Does operative treatment of geriatric pelvic ring injuries lead to a high risk of one-year mortality?

INTRODUCTION

Non-operative management of pelvic ring injuries in the elderly is associated with a high risk of one-year mortality. The majority of these injuries are the result of a low-energy mechanism, however, due to the multiple medical comorbidities in this patient population the injuries are associated with a high degree of morbidity. The purpose of this study was to determine the one-year mortality risk after operative treatment of pelvic ring injuries in a geriatric patient population and the effect of patient and injury characteristics on the risk of mortality.

PATIENTS AND METHODS

We performed a retrospective review of patients over the age of 70 who underwent operative fixation of a pelvic ring injury at two Level 1 trauma centers between January 2016 and June 2019. Medical records were reviewed for patient and injury characteristics including: Charlson Comorbidity Index (CCI), American Society of Anesthesiologists (ASA) physical status score or Injury Severity Score (ISS), hospital and intensive care unit (ICU) length of stay (LOS). The primary outcome of interest was the one-year mortality risk following operative treatment. Secondary outcomes included the effect of patient and injury characteristics on the one-year mortality risk and the hospital LOS.

RESULTS

Ninety patients were included with an average age of 79.8  ±  6.5 years. The overall mortality was 8.9% (n = 8) and was significantly associated with the CCI. There was no significant effect related to the ASA physical status score or ISS. The average hospital LOS was 9.2 ± 7.3 days and was associated with the CCI, ASA physical status score, and ISS.

DISCUSSION

Non-operative management of pelvic ring injuries in geriatric patients is associated with a high risk of one-year mortality. Our findings suggest operative treatment of these fractures is associated with an acceptable risk of one-year mortality that falls below the commonly reported range for non-operatively managed injuries. Furthermore, the risk of mortality was significantly associated with the patient's pre-injury state as determined by the CCI.

Oral Nutritional Supplements and Enteral Nutrition in Patients with Gastrointestinal Surgery

Nowadays, patients undergoing gastrointestinal surgery are following perioperative treatment in enhanced recovery after surgery (ERAS) protocols. Although oral feeding is supposed not to be stopped perioperatively with respect to ERAS, malnourished patients and inadequate calorie intake are common. Malnutrition, even in overweight or obese patients, is often underestimated. Patients at metabolic risk have to be identified early to confirm the indication for nutritional therapy. The monitoring of nutritional status postoperatively has to be considered in the hospital and after discharge, especially after surgery in the upper gastrointestinal tract, as normal oral food intake is decreased for several months. The article gives an overview of the current concepts of perioperative enteral nutrition in patients undergoing gastrointestinal surgery.

Impaired Executive Function and Depression as Independent Risk Factors for Reported Delirium Symptoms: An Observational Cohort Study Over 8 Years

BACKGROUND

Acute medical illnesses, surgical interventions, or admissions to hospital in older individuals are frequently associated with a delirium. In this cohort study, we investigated the impact of specific cognitive domains and depression before the occurrence of delirium symptoms in an 8-year observation of older non-hospitalized individuals.

METHODS

In total, we included 807 participants (48-83 years). Deficits in specific cognitive domains were measured using the CERAD test battery, and depressive symptoms were measured using Beck Depression Inventory and the Geriatric Depression Scale (GDS) before the onset of a delirium. Delirium symptoms were retrospectively assessed by a questionnaire based on the established Nursing Delirium Screening Scale.

RESULTS

Fifty-eight of eight hundred seven participants (7.2%) reported delirium symptoms over the 8-year course of the study. Sixty-nine percent (n = 40) of reported delirium symptoms were related to surgeries. In multivariate regression analysis, impaired executive function was an independent risk factor (p = 0.034) for the occurrence of delirium symptoms. Furthermore, age (p = 0.014), comorbidities [captured by the Charlson Comorbidity Index (CCI)] (p < 0.001), and depression (p = 0.012) were significantly associated with reported delirium symptoms.

CONCLUSION

Especially prior to elective surgery or medical interventions, screening for impaired executive function and depression could be helpful to identify patients who are at risk to develop delirium symptoms.

The effect of geriatric comanagement (GC) in geriatric trauma patients treated in a level 1 trauma setting: A comparison of data before and after the implementation of a certified geriatric trauma center

INTRODUCTION

Improvements in life expectancy imply that an increase of geriatric trauma patients occurs. These patients require special attention due to their multiple comorbidity issues. The aim of this study was to assess the impact of the implementation of geriatric comanagement (GC) on the allocation and clinical outcome of geriatric trauma patients.

METHODS

This observational cohort study aims to compare the demographic development and the clinical outcome in geriatric trauma patients (aged 70 years and older) before and after implementation of a certified geriatric trauma center (GC). Geriatric trauma patients admitted between January 1, 2010 and December 31, 2010 were stratified to group pre-GC and admissions between January 1, 2018 and December 31, 2018 to Group post-GC. We excluded patients requiring end-of-life treatment and those who died within 24 h or due to severe traumatic brain injury. Outcome parameters included demographic changes, medical complexity (measured by American Society of Anaesthesiology Score (ASA) and Charlson Comorbidity Index (CCI)), in-hospital mortality and length of hospitalization.

RESULTS

This study includes 626 patients in Group pre-GC (mean age 80.3 ± 6.7 years) and 841 patients in Group post-GC (mean age 81.1 ± 7.3 years). Group pre-GC included 244 (39.0%) males, group post-GC included 361 (42.9%) males. The mean CCI was 4.7 (± 1.8) points in pre-GC and 5.1 (± 2.0) points in post-GC (p <0.001). In Group pre-GC, 100 patients (16.0%) were stratified as ASA 1 compared with 47 patients (5.6%) in Group post-GC (p <0.001). Group pre-GC had significantly less patients stratified as ASA 3 or higher (n = 235, 37.5%) compared with Group post-GC (n = 389, 46.3%, p <0.001). Length of stay (LOS) decreased significantly from 10.4 (± 20.3) days in Group pre-GC to 7.9 (±22.9) days in Group post-GC (p = 0.011). The 30-day mortality rate was comparable amongst these groups (pre-GC 8.8% vs. post-GC 8.9%).

CONCLUSION

This study appears to support the implementation of a geriatric trauma center, as certain improvements in the patient care were found: Despite a higher CCI and a higher number of patients with higher ASA classifications, Hospital LOS, complication rates and mortality did were not increased after implementation of the CG. The increase in the case numbers supports the fact that a higher degree of specialization leads to a response by admitting physicians, as it exceeded the expectable trend of demographic ageing. We feel that a larger data base, hopefully in a multi center set up should be undertaken to verify these results.

[Perioperative nutritional supplementation-what is really evidence based?]

For patients undergoing major surgery, perioperative management according to an early recovery after surgery (ERAS) protocol focusing on early oral food intake is the strategy of choice. So-called perioperative nutritional (artificial) support now seems to be very traditional and outdated. Nevertheless, even in an overweight and obese society the prevalence of combined malnutrition and/or sarcopenia should not be underestimated. This results in the necessity for identification of patients at metabolic risk and the indications for nutritional therapy. This article provides a review of the current concepts of perioperative nutritional supplementation and discusses the available evidence and guideline recommendations.

Frailty as a Prognostic Indicator in Intensive Care

BACKGROUND

The percentage of patients in intensive care who are 80 years old or older is continually increasing. Such patients already made up more than 20% of all patients in intensive care in Germany in the years 2007-2011. Meanwhile, effective treatments that support the organs of the body and keep severely ill patients alive are also being continually developed and refined. Frailty is a key prognostic parameter. The scientifically based assessment of frailty can be highly useful in intensive care medicine with regard to consented decision-making, individualized prognostication, treatment planning, and aftercare.

METHODS

Pertinent publications were retrieved by a selective search in the PubMed database. On the basis of the literature assessment, a variety of screening instruments were used to assess frailty and its significance for very old, critically ill patients in German intensive care units.

RESULTS

Only a small number of screening instruments are suitable for routine use in German intensive care units. The scores vary in diagnostic precision. The Clinical Frailty Scale (CFS) enables highly accurate prognostication; it considers the patient in relation to his or her social environment, and to the reference population. Categorization is achieved by means of pictograms that are supplemented with brief written descriptions. The CFS can be used prospectively and is easy to learn. Its interrater reliability is high (weighted Cohen's κ: 0.85 [0.84; 0.87]), and it has been validated for routine use in intensive care units in Germany.

CONCLUSION

None of the available scores enable perfect prognostication. In Germany, frailty in intensive-care patients is currently best assessed on a simple visual scale (CFS).

[Anesthesiological implications of minimally invasive valve interventions : Transcatheter aortic valve implantation, clip reconstruction on the mitral and tricuspid valve]

Catheter-guided interventional implantation of cardiac valves is one of the main developments in cardiology over the past 15 years. It is characterized by a close interdisciplinary cooperation in the heart team (H-team), which consists of cardiac anesthesiologists, cardiologists and heart surgeons. This co-responsibility for anesthesia, which is demanded by the legislator (Federal Joint Committee, G‑BA, July 2015), includes not only qualified training for the cardiac anesthesiologist, including transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) but also several years of experience in cardiac anesthesia and correlates with the recommendations of the German Society for Anaesthesiology and Intensive Care Medicine. In accompaniment with the demographic development, the number of heart valve diseases increases with age. More than 50% of all heart operations are performed on patients over the age of 70 years and nearly 20% on patients over the age of 80 years. Minimally invasive procedures are outstanding opportunities for patients who were initially classified as inoperable. Therefore, anesthesiologists must have precise knowledge of the possible complications related to the procedure itself. Additionally, it challenges the anesthesiologist with unconventional situations in the care of older patients who are exposed to a higher risk. The aforementioned risks are organic functional restrictions, increasing number of comorbidities and more severe exposure due to malnutrition and frailty; however, monitoring methods are also being developed aiming for patient-specific anesthesia management and analgesia treatment. This article discusses the interventional procedures of heart valvular diseases as well as the hemodynamic changes associated with the procedures from the anesthesiologist's point of view. To present examples, we have selected transcatheter aortic valve replacement (TAVR) and the interventional procedure of mitral and tricuspid valve insufficiency called MitraClip and TricaClip. A thorough examination of the procedural risk rate shows that despite minimizing the surgical intervention by miniaturizing the devices, the presence of an experienced cardiac anesthesiologist is obligatory.

Pancreatic Resection in Older Patients: A Retrospective Single-Center Outcome Analysis

Due to increasing life expectancy and improved diagnostic sensitivity, a growing number of older patients are presenting with resectable pancreatic disease entities and are being evaluated for surgery. Intended as an internal quality control for patient selection, we aimed at evaluating septuagenarians and octogenarians compared with patients younger than 70 years of age regarding early postoperative outcome in general, and long-term oncologic outcome in the case of resection for pancreatic adenocarcinoma. A total number of 1231 patients who underwent pancreatic resection for any entity between 2007 and 2019 at our tertiary university medical center in Germany were retrospectively analyzed, accessing a prospectively maintained database. Participants were divided into three groups based on age (<70 years: N = 761; 70–79 years: N = 385; 80–89 years: N = 85) and were evaluated with regard to perioperative variables, postoperative morbidity, mortality and overall survival for the subgroup of patients with pancreatic adenocarcinoma. Pancreatic resection in older individuals was not infrequent. When surgery was performed for carcinoma, patients >70 years of age even constituted almost half of the cases. In spite of increased American Society of Anesthesiologists physical status classification (ASA)-scores and more frequent comorbidities in older patients, similar rates for postoperative morbidity and mortality were observed in all age groups. A significant disparity in the use of (neo-) adjuvant therapy between younger and older pancreatic adenocarcinoma patients was detected. However, median overall survival did not significantly differ between all age groups (<70 years: 28 (95%-CI: 22–34) months; 70–79 years: 21 (17–25) months; 80–89 years: 15 (9–21) months). In conclusion, elderly patients can experience similar perioperative outcomes to those of younger individuals after major pancreatic surgery. The survival benefit from resection of localized pancreatic adenocarcinoma is largely independent of patient age. The results are reassuring with respect to our preoperative practice and clinical judgment regarding careful patient selection. Future randomized trials should decidedly include elderly patients to generate more robust evidence to further optimize treatment recommendation and choice.

[Challenges of discharge management in geriatric traumatology : Example of an integrated orthogeriatric service]

BACKGROUND

Geriatric patients are currently responsible for almost one third of all emergency hospital admissions. An increase of 50% is expected in the next decade. This age redistribution poses new challenges for inpatient care and discharge management. The requirements of an orthopedic trauma surgery clinic in the care of this patient group can be clarified with the help of this first collaboratively created geriatric orthopedic trauma surgery complex treatment unit of a university hospital.

OBJECTIVE

What influence do age and delirium have on discharge management, length of inpatient stay and discharge destination in a geriatric cohort?

MATERIAL AND METHODS

All patients who received inpatient treatment as part of the orthopedic trauma surgery geriatric complex treatment (GKB) between May 2017 and December 2019 were evaluated. An analysis of the demographics, length of inpatient stay, discharge destinations and evaluation of the Barthel index collected on admission and discharge, the mini-mental state examination (MMSE) and the geriatric depression scale (GDS) were carried out.

RESULTS

Out of 312 patients, 110 men and 193 women with a median age of 81 years, 77 patients (24.6%) showed delirium when enrolled in the GKB and 39 (12.5%) dementia. Older patients presented more often with delirium than younger people (p = 0.013), especially those aged 70-79 years (p = 0.037). Dementia patients suffered more frequently from postoperative delirium (p < 0.01). The mean hospital stay was 17.79 days (±4.6 days). The GKB was regularly completed in 60.7% of all cases and 39.3% patients dropped out early. Patients with delirium were discharged significantly less often into their own home but into short-term care or nursing homes (p = 0.038). A general correlation between delirium development and the discharge destination was noticeable (p = 0.004).

CONCLUSION

Patients with dementia are more likely to develop delirium postoperatively, which leads to an increase in the length of inpatient stay, an increase in treatment costs and more work for the discharge management team. In addition, the discharge to the patients' home is impaired by delirium, which means that the growing need for places in short-term care and nursing homes also creates socioeconomic burdens.

[Perioperative management of polymedication in geriatric patients: risk reduction and coordination with the family practitioner]

The increasing proportion of older and polymorbid people in the population also means an increase in polymedication and its risks. This places new and complex demands on the interdisciplinary and transsectoral collaboration. The preoperative, perioperative and postoperative management of polymedication is described in the article with respect to frequent risks and the chances of a systematic exchange of information. The establishment of an interdisciplinary admission routine in departments of surgery and communication with the family practitioner is crucial for patient safety.

Diverging Awareness of Postoperative Delirium and Cognitive Dysfunction in German Health Care Providers

PURPOSE

Postoperative cognitive dysfunction (POCD) appears in up to 30% of patients suffering from postoperative delirium (POD). Both are associated with higher mortality and postoperative complications, prolonged hospital stays, and increased costs. Multi-modal models with pre-admission risk reduction counselling, perioperative monitoring, and training of multidisciplinary patient care providers have been shown to decrease the prevalence of both. The aim of our study is to understand how far those measures are known and implemented in routine care and to detect potential gaps in the current practice regarding risk communication and information flow between involved caregivers for patients at risk for POD/POCD.

PATIENTS AND METHODS

As part of a multicenter study, seven semi-structured focus group (FG) discussions with nurses and physicians from tertiary care hospitals (surgery, anesthesiology, and orthopedics, n=31) and general practitioners (GPs) in private practice (n=7) were performed. Transcribed discussions were analyzed using qualitative content analysis.

RESULTS

POD is present above all in the daily work of nurses, whereas physicians do not perceive it as a relevant problem. Physicians report that no regular risk assessment or risk communication was performed prior to elective surgery. Information about POD often gets lost during hand-offs and is not regularly reported in discharge letters. Thus, persisting cognitive dysfunction is often missed. The importance of standardized documentation and continuous education concerning risks, screening, and treatment was emphasized. The often-suggested pre-OP medication adjustment was seen as less important; in contrast, avoiding withdrawal was regarded as far more important.

CONCLUSION

Altogether, it seems that standards and available best practice concepts are rarely implemented. In contrast to physicians, nurses are highly aware of delirium and ask for standardized procedures and more responsibility. Therefore, raising awareness regarding risks, screening tools, and effective preventive measures for POD/POCD seems an urgent goal. Nurses should have a central role in coordination and care of POD to prevent the risk for POCD.

Is there a rationale for perioperative nutrition therapy in the times of ERAS?

In order to increase patient compliance in Enhanced Recovery after Surgery (ERAS) programs, assessment and monitoring of functional and nutritional status should be routinely performed. Sarcopenic obesity is frequently underestimated and has been shown to be a significant risk factor for the development of postoperative complications. With special regard to gastrointestinal cancer patients undergoing neoadjuvant treatment, nutritional deficiencies may develop stepwise and increase during therapy. In the case of proven deficits, recent strategies including "prehabilitation" focus on making the patient fit for an ERAS program. Evidence-based guidelines for perioperative nutrition therapy have been available.

[Preoperative cognitive function in very old patients : Influence on the complication rate and length of hospitalization]

BACKGROUND

Gastrointestinal cancer is a frequent diagnosis in older patients. A curative resection, possibly in combination with radiotherapy and/or chemotherapy, is the standard therapy. The advanced age of the patients with an increasing number of comorbidities and often the presence of cognitive impairment represents a high risk for perioperative complications and a longer stay in hospital. The challenge in the clinical routine is to recognize a cognitive impairment in older patients and to prepare these patients for the operative intervention in the best possible way.

OBJECTIVE

This retrospective analysis was carried out to find out whether preoperative cognitive impairment is a prognostic factor for the postoperative outcome.

METHODS

In patients over the age of 75 years who were prepared for abdominal surgery of gastrointestinal cancer in the preoperative consultation, the mini mental state examination (MMSE) and the clock test were carried out. The results of the tests were retrospectively compared with the complication rate and the duration of hospital stay.

RESULTS

Low MMSE values were significantly associated with the complication rate and the development of a severe complication (Clavien-Dindo grade ≥ 3a). A cut-off value of 24 points in the MMSE was predictive for the development of complications and a longer hospital stay. The age of the patients was not associated with the MMSE.

CONCLUSION

Cognitive impairment is an important prognostic factor for the development of perioperative complications and the duration of the hospital stay in patients undergoing extensive abdominal surgery for gastrointestinal cancer. Therefore, a preoperative assessment, for example with the MMSE, is recommended in order to identify high-risk patients.

Anesthetic management of geriatric patients

The number of elderly patients who frequently access health care services is increasing worldwide. While anesthesiologists are developing the expertise to care for these elderly patients, areas of concern remain. We conducted a comprehensive search of major international databases (PubMed, Embase, and Cochrane) and a Korean database (KoreaMed) to review preoperative considerations, intraoperative management, and postoperative problems when anesthetizing elderly patients. Preoperative preparation of elderly patients included functional assessment to identify preexisting cognitive impairment or cardiopulmonary reserve, depression, frailty, nutrition, polypharmacy, and anticoagulation issues. Intraoperative management included anesthetic mode and pharmacology, monitoring, intravenous fluid or transfusion management, lung-protective ventilation, and prevention of hypothermia. Postoperative checklists included perioperative analgesia, postoperative delirium and cognitive dysfunction, and other complications. A higher level of perioperative care was required for older surgical patients, as multiple chronic diseases often makes them prone to developing postoperative complications, including functional decline and loss of independence. Although the guiding evidence remains poor so far, elderly patients have to be provided optimal perioperative care through close interdisciplinary, interprofessional, and cross-sectional collaboration to minimize unwanted postoperative outcomes. Furthermore, along with adequate anesthetic care, well-planned postoperative care should begin immediately after surgery and extend until discharge.

[Preoperative conditioning in ageing patients-gerontosurgery]

Adapting the daily hospital routine to changes in the aging structure of society and the patients will be one of the main challenges for surgeons in the coming years. Important factors regarding the outcome of aging patients will be preoperative conditioning, specific age-adapted surgical strategies and the organization of the hospital infrastructure. Nutritional protocols and liquid intake schedules should be taken into account as well as cognitive assessment tools and strategies to protect aging patients from postoperative delirium. The importance of changes in metabolism and the concomitant comorbidities are very similar in most specialty disciplines. The lack of a clear and widely accepted definition of biological age and the missing adaptations of, e. g. complication scores, currently exacerbate the compilation of a resilient survey. In the absence of a reimbursement-system for geriatric medicine it will be very difficult to achieve the necessary structural changes in the treatment regimens for older patients. The establishment of the necessary surgical treatment adapted to the needs of older patients therefore remains a challenging task.
