Preoperative Risk Factors for Adverse Events in Adults Undergoing Bowel Resection for Inflammatory Bowel Disease: 15-Year Assessment of the American College of Surgeons National Surgical Quality Improvement Program

Frailty integration in medical specialties: Current evidence and suggested strategies from the Clin-STAR frailty interest group

Frailty is a syndrome that can inform clinical treatments and interventions for older adults. Although implementation of frailty across medical subspecialties has the potential to improve care for the aging population, its uptake has been heterogenous. While frailty assessment is highly integrated into certain medical subspecialties, other subspecialties have only recently begun to consider frailty in the context of patient care. In order to advance the field of frailty-informed care, we aim to detail what is known about frailty within the subspecialties of internal medicine. In doing so, we highlight cross-disciplinary approaches that can enhance our understanding of frailty, focusing on ways to improve the implementation of frailty measures, as well as develop potential interventional strategies to mitigate frailty within these subspecialties. This has important implications for the clinical care of the aging population and can help guide future research.

A Comprehensive Review of Geriatric Syndromes and Assessment in Older Adults With Inflammatory Bowel Diseases

OBJECTIVE & AIMS

Older patients with inflammatory bowel disease (IBD) constitute an increasingly prevalent population. There is growing recognition of the prevalence and impact of geriatric syndromes on patients with IBD. We aimed to critically review available data on geriatric syndromes in patients with IBD.

METHODS

An electronic systematic bibliographic search was performed in April 2024 using PubMed to identify relevant literature on frailty, functional status assessment, and geriatric syndromes among older adults with IBD.

RESULTS

Frailty is prevalent among patients of all ages with IBD and is associated with worse outcomes. It is associated with an increased risk of infections but may be ameliorated through effective treatment of underlying inflammation. There is less understanding of other geriatric syndromes, such as multi-morbidity, polypharmacy, sarcopenia, fecal incontinence, physical function, falls, fatigue, social isolation, and cognitive impairment in older patients with IBD; existing data suggests an important negative impact of all these syndromes on older adults with IBD.

CONCLUSIONS

Geriatric syndromes are prevalent and negatively impact older patients with IBD. Systematic assessment for their presence and multidisciplinary interventions to improve them are important to improve outcomes of older adults with IBD.

Exclusion diet and fasting practices in patients with inflammatory bowel disease: Impact on nutritional status

BACKGROUND

Undernutrition is purportedly highly prevalent in inflammatory bowel diseases (IBD). While several risk factors have been identified, the impact of widespread eating behaviors such as food exclusions and therapeutic fasting practices has not been evaluated. There are limited data on the prevalence of undernutrition diagnosed according to internationally recognized criteria in this population.

OBJECTIVES

To estimate the prevalence of undernutrition assessed with the Global Leadership Initiative on Undernutrition (GLIM) criteria and to analyze factors associated with the characteristics of the disease and factors related to undernutrition.

METHODS

Patients attending our IBD nutrition clinic were screened between November 2021 and April 2022. The complete avoidance of a food category was defined as total exclusion while avoidance most of the time was defined as partial exclusion. Undernutrition was diagnosed according to GLIM criteria. Weight history, past maximal involuntary weight loss and minimal body mass index since diagnosis of IBD were also collected.

RESULTS

A total of 434 patients with IBD were included. Undernutrition was observed in 25.8 % of the whole population at inclusion (15 % with moderate undernutrition and 10.8 % with severe undernutrition). Mean involuntary maximal weight loss since illness onset was -14.5 % ± 11.0. Previous undernutrition since IBD diagnosis was reported in 81.1 % of the population, 63.6 % for severe and 17.5 % for moderate undernutrition. In multivariate analysis, undernutrition at inclusion was independently associated with total exclusion of at least one food category (OR = 1.11 95 % CI, 1.01-1.22; p = 0.031) as well as active disease (OR = 1.16 95 % CI, 1.05-1.27; p = 0.002), and negatively with the duration of IBD (OR = 0.88 95 % CI, 0.78-0.99, p = 0.031). Exclusion diet was also the main variable significantly associated with episodes of undernutrition in the past (OR = 1.11 95 % CI, 1.01-1.22; p = 0.035) as well as previous surgery (OR = 1.11 95 % CI, 1.00-1.23; p = 0.048). In these analyses, fasting practices were not independently associated with a risk of undernutrition.

CONCLUSION

Total exclusion of at least one food category was one of the main factors associated with undernutrition independently of disease activity and duration, both at the time of inclusion and in the past, and should be avoided, whereas fasting practices were not associated with a risk of undernutrition.

Frailty: An Underappreciated Risk Factor for IBD Complications

PURPOSE OF REVIEW

The prevalence of IBD in older adults is rapidly growing. Older adults with IBD are underrepresented in research and clinical trials and yet at great risk for adverse events. Therefore, understanding advanced aged associated constructs in older adults can be critical to improving the management of older adults with IBD.

RECENT FINDINGS

In this review, we present recent studies on frailty in IBD. We identify 4 major themes in the literature: studies that describe frailty in patients with IBD, studies that report on consequences of frailty, studies of frailty as a risk stratification modality, and studies of frailty as an exposure and outcome. In reviewing the literature, we discuss the heterogeneity that exists and outline future directions to ensure appropriate applications for frailty in the field of IBD.

Sarcopenia Is a Risk Factor for Postoperative Complications Among Older Adults With Inflammatory Bowel Disease

BACKGROUND

Sarcopenia has been associated with adverse postoperative outcomes in older age cohorts, but has not been assessed in older adults with inflammatory bowel disease (IBD). Further, current assessments of sarcopenia among all aged individuals with IBD have used various measures of muscle mass as well as cutoffs to define its presence, leading to heterogeneous findings.

METHODS

In this single-institution, multihospital retrospective study, we identified all patients aged 60 years and older with IBD who underwent disease-related intestinal resection between 2012 and 2022. Skeletal Muscle Index (SMI) and Total Psoas Index (TPI) were measured at the superior L3 endplate on preoperative computed tomography scans and compared through receiver operating characteristic curve. We then performed multivariable logistic regression to assess risk factors associated with an adverse 30-day postoperative outcome. Our primary outcome included a 30-day composite of postoperative mortality and complications, including infection, bleeding, cardiac event, cerebrovascular accident, acute kidney injury, venous thromboembolism, reoperation, all-cause rehospitalization, and need for intensive care unit-level care.

RESULTS

A total of 120 individuals were included. Overall, 52% were female, 40% had ulcerative colitis, 60% had Crohn's disease, and median age at time of surgery was 70 years (interquartile range: 65-75). Forty percent of older adults had an adverse 30-day postoperative outcome, including infection (23%), readmission (17%), acute kidney injury (13%), bleeding (13%), intensive care unit admission (10%), cardiac event (8%), venous thromboembolism (7%), reoperation (6%), mortality (5%), and cerebrovascular accident (2%). When evaluating the predictive performance of SMI vs TPI for an adverse 30-day postoperative event, SMI had a significantly higher area under the curve of 0.66 (95% CI, 0.56-0.76) as compared to 0.58 (95% CI, 0.48-0.69) for TPI (P = .02). On multivariable logistic regression, prior IBD-related surgery (adjusted odds ratio [adjOR] 6.46, 95% CI, 1.85-22.51) and preoperative sepsis (adjOR 5.74, 95% CI, 1.36-24.17) significantly increased the odds of adverse postoperative outcomes, whereas increasing SMI was associated with a decreased risk of an adverse postoperative outcome (adjOR 0.88, 95% CI, 0.82-0.94).

CONCLUSIONS

Sarcopenia, as measured by SMI, is associated with an increased risk of postoperative complications among older adults with IBD. Measurement of SMI from preoperative imaging can help risk stratify older adults with IBD undergoing intestinal resection.

Surgical Emergencies in Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) patients are at risk for undergoing emergency surgery for fulminant disease, toxic megacolon, bowel perforation, intestinal obstruction, or uncontrolled gastrointestinal hemorrhage. Unfortunately, medical advancements have failed to significantly decrease rates of emergency surgery for IBD. It is therefore important for all acute care and colorectal surgeons to understand the unique considerations owed to this often-challenging patient population.

Sarcopenia as a Preoperative Risk Stratification Tool among Older Adults with Inflammatory Bowel Disease

Sarcopenia, defined as a loss of muscle mass and function, is a physiologic factor that has been implicated as a predictor of adverse postoperative outcomes in many older adult populations. However, data related to sarcopenia in older adults with inflammatory bowel disease (IBD) remain limited. Older adults with IBD are particularly vulnerable to adverse postoperative outcomes, in part, due to muscle depletion from systemic inflammation, malnutrition, and reduced physical activity. However, few patients undergo routine muscle evaluation as a part of preoperative assessment. Moreover, cut-off values for measures of sarcopenia in the literature are modeled after non-IBD populations. The lack of standardized measures and values for sarcopenia in the IBD patient population has led to heterogenous findings and a paucity of preoperative risk stratification tools. Therefore, we aim to explore the scope of sarcopenia as a preoperative risk stratification tool among older adults with IBD.

The implementation of an inflammatory bowel disease-specific enhanced recovery after surgery protocol: an observational cohort study

BACKGROUND

The implementation of Enhanced Recovery After Surgery (ERAS) protocols has resulted in improved postoperative outcomes in colorectal cancer surgery. The evidence regarding feasibility and impact on outcomes in surgery for inflammatory bowel disease (IBD) is limited.

METHODS

We performed a retrospective observational cohort study, comparing patient trajectories before and after implementing an IBD-specific ERAS protocol at Zealand University Hospital. We assessed the occurrence of serious postoperative complications of Clavien-Dindo grade 3 or higher as our primary outcome, with postoperative length of stay in days and rate of readmissions as secondary outcomes, using χ2, Mann-Whitney test, and odds ratios adjusted for sex and age.

RESULTS

From 2017 to 2023, 394 patients were operated on for IBD and included in our study. In the ERAS cohort, 39/250 patients experienced a postoperative complication of Clavien-Dindo grade 3 or higher compared to 27/144 patients in the non-ERAS cohort (15.6% vs. 18.8%, p = 0.420) with an adjusted odds ratio of 0.73 (95% CI 0.42-1.28). There was a significantly shorter postoperative length of stay (median 4 vs. 6 days, p < 0.001) in the ERAS cohort compared to the non-ERAS cohort. Readmission rates remained similar (22.4% vs. 16.0%, p = 0.125).

CONCLUSIONS

ERAS in IBD surgery was associated with faster patient recovery, but without an impact on the occurrence of serious postoperative complications and rate of readmissions.

Optimal Management of Refractory Crohn's Disease: Current Landscape and Future Direction

Refractory Crohn's disease, defined as ongoing inflammation despite the trial of multiple advanced therapies, impacts a number of individuals with Crohn's disease, and leads to significant burden in quality of life and cost. Interventions such as early implementation of advanced therapies, optimization of current therapies prior to switching to an alternative, as well as understanding the overlapping pathophysiology between immune-mediated disorders, however, can help shift the current landscape and reduce the number of patients with refractory disease. As such, in this review we summarize the key takeaways of the latest research in the management of moderate-to-severe Crohn's disease, focusing on maximization of our currently available medications, while also exploring topics such as combination advanced therapies. We also describe evidence for emerging and alternative therapeutic modalities, including fecal microbiota transplant, exclusive enteral feeding, hyperbaric oxygen, stem cell therapy, bone marrow transplant, and posaconazole, with a focus on both the potential impact and specific indications for each.

Management Considerations for the Older Adult With Inflammatory Bowel Disease

As the prevalence of older adults with inflammatory bowel disease (IBD) is rising, understanding the unique challenges in both diagnosis and management is becoming increasingly important. Knowledge of phenotypic differences as well as overlapping symptoms with other medical conditions is critical to obtaining a timely diagnosis of IBD in older adults. Although older adults with IBD are at higher risk for adverse events compared with younger adults with IBD, recent data have suggested that ongoing disease activity may be a significant driver of adverse clinical outcomes rather than use of current treatment modalities. Ultimately, earlier and effective treatments can improve outcomes and quality of life for older adults with IBD. However, to help improve medical decision-making, clinicians must move away from the use of chronological age alone and begin to integrate measures of biological age, such as frailty and sarcopenia, into risk stratification tools. This article reviews the management considerations for older adults with IBD and provides the rationale for incorporating measures of biological age into current practice.
