Association of Patient Frailty With Increased Morbidity After Common Ambulatory General Surgery Operations

Accuracy of frailty instruments in predicting outcomes following perioperative cardiac arrest

BACKGROUND

Frailty is associated with increased 30-day mortality and non-home discharge following perioperative cardiac arrest. We estimated the predictive accuracy of frailty when added to baseline risk prediction models.

METHODS

In this retrospective cohort study using 2015-2020 NSQIP data for 3048 patients aged 50+ undergoing non-cardiac surgery and resuscitation on post-operative day 0 (i.e., intraoperatively or postoperatively on the day of surgery), baseline models including age, sex, ASA physical status, preoperative sepsis or septic shock, and emergent surgery were compared to models that added frailty indices, either RAI or mFI-5, to predict 30-day mortality and non-home discharge. Predictive accuracy was characterized by area under the receiver operating characteristic curve (AUC-ROC), integrated calibration index (ICI), and continuous net reclassification index (NRI).

RESULTS

1786 patients (58.6%) died in the study cohort within 30 days, and 38.6% of eligible patients experienced non-home discharge. The baseline model showed good discrimination (AUC-ROC 0.77 for 30-day mortality and 0.74 for non-home discharge). AUC-ROC and ICI did not significantly change after adding frailty for 30-day mortality or non-home discharge. Adding RAI significantly improved NRI for 30-day mortality and non-home discharge; however, the magnitude was small and difficult to interpret, given other results including false positive and negative rates showing no difference in predictive accuracy.

CONCLUSIONS

Incorporating frailty did not significantly improve predictive accuracy of models for 30-day mortality and non-home discharge following perioperative resuscitation. Thus, demonstrated associations between frailty and outcomes of perioperative resuscitation may not translate into improved predictive accuracy. When engaging patients in shared decision-making regarding do-not-resuscitate orders perioperatively, providers should acknowledge uncertainty in anticipating resuscitation outcomes.

Outcomes and quality of life of frail patients following elective ventral hernia repair: Retrospective review of a national hernia collaborative

BACKGROUND

Ventral hernia repair (VHR) is one of the most common general surgery procedures among older adults but is often deferred due to a higher risk of complications. This study compares postoperative quality of life (QOL) and complications between frail and non-frail patients undergoing elective VHR. We hypothesized that frail patients would have higher complication rates and smaller gains in quality of life compared to non-frail patients.

STUDY DESIGN

Patients 65 years of age and older, undergoing elective VHR between 2018 and 2022 were selected from the ACHQC (Abdominal Core Health Quality Collaborative) and grouped based on frailty scores obtained using the Modified Frailty Index (mFI-5). Logistic regression adjusting for hernia characteristics (size, recurrent, parastomal, incisional) were performed for 30-day outcomes including surgical site infections (SSI), surgical site occurrences (SSO), surgical site infections/occurrences requiring procedural intervention (SSOPI), and readmission. Multivariable analyses controlling for patient and procedure characteristics were performed comparing QOL scores (HerQLes scale, 0-100) at baseline, 30 days, 6 months and 1 year postoperatively.

RESULTS

A total of 4888 patients were included, 29.17% non-frail, 47.87% frail, and 22.95% severely frail. On adjusted analysis, severely frail patients had higher odds of SSO (most commonly seroma formation) but no evidence of a difference in SSI, SSOPI, readmission or mortality. Severely frail patients had lower median QOL scores at baseline (48.3/100, IQR 26.1-71.7, p ​= ​0.001) but reported higher QOL scores at both 30-days (68.3/100, IQR 41.7-88.3, p ​= ​0.01) and 6-months (86.7/100, IQR 65.0-93.3, p ​= ​0.005).

CONCLUSION

Severely frail patients reported similar increases in QOL and similar complications to their not frail counterparts. Our results demonstrate that appropriately selected older patients, even those who are severely frail, may benefit from elective VHR in the appropriate clinical circumstance.

Frailty is an independent predictor of postoperative rescue medication use after endoscopic sinus surgery

INTRODUCTION

The modified five-item frailty index (mFI-5) is a validated risk stratification tool with the ability to predict adverse outcomes following surgery. In this study, we sought to use mFI-5 to assess the potential relationship between unhealthy aging and postoperative endoscopic sinus surgery (ESS) outcomes.

METHODS

Patients who underwent sinus surgery at Vanderbilt between 2014 and 2018 were identified and assessed using the mFI-5, which is calculated based on the presence of five comorbidities: diabetes mellitus, hypertension requiring medication, chronic obstructive pulmonary disease, congestive heart failure, and non-independent functional status. Multivariate regression analyses were performed to quantify the association of mFI-5 score on need for rescue oral antibiotics, oral steroids, and antibiotic irrigations within 1 year following ESS, adjusting for relevant potential confounders.

RESULTS

Four hundred and three patients met inclusion criteria.  Within 6 months of surgery, 312 (77%) required rescue antibiotics, 243 (60%) required oral corticosteroids (OCS), and 31 (8%) initiated antibiotic irrigations. Increasing mFI-5 scores were significantly associated with higher postoperative use of rescue antibiotics (p < 0.0001), OCS (p = 0.032), and antibiotic irrigation (p < 0.0001). Frailty scores remained as an independent predictor of these outcomes after adjustment for age, polyp status, preoperative sinonasal outcomes test (SNOT-22) score, and revision surgery status.

CONCLUSIONS

Modified frailty scores may be a useful clinical tool to predict the need for postoperative rescue medication use after ESS.

The association of hernia-specific and procedural risk factors with early complications in ventral hernia repair: ACHQC analysis

BACKGROUND

Many surgical risk assessment tools emphasize patient-specific risk factors. Our objective was to use a hernia-specific database to assess risk factors of complications in ventral hernia repair (VHR) focusing on hernia-specific and procedural factors.

METHODS

The ACHQC database was queried for elective VHR in adults from 2012 to 2023. Primary outcome was overall 30-day complications. Multivariable logistic regression was used for analysis.

RESULTS

41,526 VHR were included. The rate of 30-day complications was 18%, surgical site infection 3%, surgical site occurrence requiring procedural intervention 4%, readmission 4%, reoperation 2%, and mortality 0.2%. Multivariable analysis demonstrated that BMI, ASA, frailty, COPD, anticoagulants, defect width, incisional and recurrent hernias, presence of stoma or prior mesh, prior abdominal wall infection, non-clean wound, operative time, open approach and myofascial release were associated with 30-day complications (OR ​= ​1.01-1.66). Preoperative chlorhexidine, bowel preparation and fascial closure were associated with lower complication risk (OR ​= ​0.70-0.89).

CONCLUSION

Hernia and procedural risk factors are associated with early complications following elective VHR. These factors need to be included in surgical risk assessment tools, to supplement patient-specific factors.

Impact of frailty on post-operative outcomes following subarachnoid hemorrhage: A systematic review and meta-analysis

BACKGROUND

Subarachnoid hemorrhage (SAH) is associated with high rates of mortality and morbidity, particularly among elderly patients. The presence of frailty may impact survival rates in patients with SAH. In this study, we aim to investigate the impact of frailty on the clinical outcomes in SAH patients.

METHODS

We conducted a systematic review and meta-analysis following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Relevant papers through December 2023 were retrieved from PubMed, Scopus, Web of science, and Embase.

RESULTS

A total of 5 studies met inclusion/exclusion criteria with an aggregate 39,221 non-frail patients (mean age 52.4 ± 5.2 yr; 62.1 % Female), and 79,416 frail patients (mean age 61.1 ± 5.4 yr; 69.0 % Female). Frailty was significantly associated with higher mortality ratio (Odds ratio (OR)= 2.09; CI [1.04: 4.20], p= 0.04), and increased length of hospital stay (OR= 1.40; CI [1.07: 1.83], p= 0.015). Additionally, frailty was associated with higher odds of external ventricular drain insertion, the need of tracheostomy/endoscopic gastrostomy, increased risk of deep vein thrombosis, and postoperative neurological complications.

CONCLUSION

Frailty is associated with worse clinical outcomes and higher mortality rates in SAH patients. Our findings highlight that frailty, when considered alongside other established prognostic factors, serves as crucial predictor for peri-operative complications and overall hospital course in SAH patients.

Lingering effects of COVID-19 in the care of perioperative patients

PURPOSE OF REVIEW

Coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), can lead to organ dysfunction and clinical symptoms beyond the acute infection phase. These effects may have significant implications for the management of perioperative patients. The purpose of this article is to provide a systems-based approach to the subacute and chronic effects of SARS-CoV-2 that are most relevant to anesthesiology practice.

RECENT FINDINGS

In 2024, COVID-19 remains a concern for anesthesiologists due ongoing new infections, evolving viral strains, and relatively low rates of booster vaccination in the general population. A growing body of literature describes the post-COVID-19 syndrome in which patients experience symptoms more than 12 weeks after acute infection. Recent literature describes the lingering effects of SARS-CoV-2 infection on all major organ systems, including neurologic, pulmonary, cardiovascular, renal, hematologic, and musculoskeletal, and suggests an increased perioperative mortality risk in some populations.

SUMMARY

This review offers anesthesiologists an organ system-based approach to patients with a history of COVID-19. Recognizing the long-term sequelae of SARS-CoV-2 infection can help anesthesiologists to better evaluate perioperative risk, anticipate clinical challenges, and thereby optimize patient care.

The Modified Frailty Index Predicts Major Complications in Oncoplastic Reduction Mammoplasty

BACKGROUND

An important component of preoperative counseling and patient selection involves surgical risk stratification. There are many tools developed to predict surgical complications. The Modified Frailty Index (mFI) calculates risk based on the following five elements: hypertension, chronic obstructive pulmonary disease, congestive heart failure, diabetes, and functional status. Recent literature demonstrates the efficacy of the mFI across multiple surgical disciplines. We elected to investigate its utility in oncoplastic reductions (OCR).

METHODS

A retrospective review of all patients with breast cancer who underwent OCR from 1998 to 2020 was queried from a prospectively maintained database. Patient demographics, comorbidities, and surgical details were reviewed. The mFI was computed for each patient. The primary clinical outcome was the development of complications.

RESULTS

547 patients were included in the study cohort. The average age was 55 and the average body mass index was 33.5. The overall complication rate was 19% (n = 105) and the major complication rate was 9% (n = 49). Higher frailty scores were significantly associated with the development of major complications (P < 0.05). mFI scores of 0 had a major complication rate of 5.7%; scores of 1, 13%; and scores of 2, 15.1%. The relative risk of a major complication in patients with elevated mFI (>0) was 2.2. Age, body mass index, and resection weights were not associated with complications (P = 0.15, P = 0.87, and P = 0.30 respectively) on continuous analysis.

CONCLUSIONS

Elevated mFI scores are associated with an increased major complication profile in patients who are undergoing OCR. Hypertension and diabetes are the most common comorbidities in our population, and this tool may assist with preoperative counseling and risk stratification. Benefits of this risk assessment tool include its ease of calculation and brevity. Our study is the first to demonstrate its utility in OCR; however, further study in high-risk patients would strengthen the applicability of this frailty index.

Impact of frailty on survival glioblastoma, IDH-wildtype patients

PURPOSE

Frailty increases the risk of mortality among patients. We studied the prognostic significance of frailty using the modified 5-item frailty index (5-mFI) in patients harboring a newly diagnosed supratentorial glioblastoma, IDH-wildtype.

METHODS

We retrospectively reviewed records of patients surgical treated at a single neurosurgical institution at the standard radiochemotherapy era (January 2006 - December 2021). Inclusion criteria were: age ≥ 18, newly diagnosed glioblastoma, IDH-wildtype, supratentorial location, available data to assess the 5-mFI index.

RESULTS

A total of 694 adult patients were included. The median overall survival was longer in the non-frail subgroup (5-mFI < 2, n = 538 patients; 14.3 months, 95%CI 12.5-16.0) than in the frail subgroup (5-mFI ≥ 2, n = 156 patients; 4.7 months, 95%CI 4.0-6.5 months; p < 0.001). 5-mFI ≥ 2 (adjusted Hazard Ratio (aHR) 1.31; 95%CI 1.07-1.61; p = 0.009) was an independent predictor of a shorter overall survival while age ≤ 60 years (aHR 0.78; 95%CI 0.66-0.93; p = 0.007), KPS score ≥ 70 (aHR 0.71; 95%CI 0.58-0.87; p = 0.001), unilateral location (aHR 0.67; 95%CI 0.52-0.87; p = 0.002), total removal (aHR 0.54; 95%CI 0.44-0.64; p < 0.0001), and standard radiochemotherapy protocol (aHR 0.32; 95%CI 0.26-0.38; p < 0.0001) were independent predictors of a longer overall survival. Frailty remained an independent predictor of overall survival within the subgroup of patients undergoing a first-line oncological treatment after surgery (n = 549) and within the subgroup of patients who benefited from a total removal plus adjuvant standard radiochemotherapy (n = 209).

CONCLUSION

In newly diagnosed supratentorial glioblastoma, IDH-wildtype patients treated at the standard combined radiochemotherapy era, frailty, defined using a 5-mFI score ≥ 2 was an independent predictor of overall survival.

The risk analysis index is an independent predictor of outcomes after lung cancer resection

BACKGROUND

The Risk Analysis Index (RAI) is a frailty assessment tool based on an accumulation of deficits model. We mapped RAI to data from the Society of Thoracic Surgeons (STS) Database to determine whether RAI correlates with postoperative outcomes following lung cancer resection.

METHODOLOGY/PRINCIPAL FINDINGS

This was a national database retrospective observational study based on data from the STS Database. Study patients underwent surgery 2018 to 2020. RAI was divided into four increasing risk categories. The associations between RAI and each of postoperative complications and administrative outcomes were examined using logistic regression models. We also compared the performance of RAI to established risk indices (American Society of Anesthesiology (ASA) and Charlson Comorbidity Index (CCI)) using areas under the Receiver Operating Characteristic (ROC) curves (AUC). Results: Of 29,420 candidate patients identified in the STS Database, RAI could be calculated for 22,848 (78%). Almost all outcome categories exhibited a progressive increase in marginal probability as RAI increased. On multivariable analyses, RAI was significantly associated with an incremental pattern with almost all outcomes. ROC analyses for RAI demonstrated "good" AUC values for mortality (0.785; 0.748) and discharge location (0.791), but only "fair" values for all other outcome categories (0.618 to 0.690). RAI performed similarly to ASA and CCI in terms of AUC score categories.

CONCLUSIONS/SIGNIFICANCE

RAI is associated with clinical and administrative outcomes following lung cancer resection. However, its overall accuracy as a surgical risk predictor is only moderate and similar to ASA and CCI. We do not recommend routine use of RAI for assessment of individual patient risk for major lung resection.

Comparison of three frailty scales for prediction of prolonged postoperative ileus following major abdominal surgery in elderly patients: a prospective cohort study

BACKGROUND

To determine whether frailty can predict prolonged postoperative ileus (PPOI) in older abdominal surgical patients; and to compare predictive ability of the FRAIL scale, the five-point modified frailty index (mFI-5) and Groningen Frailty Indicator (GFI) for PPOI.

METHODS

Patients (aged ≥ 65 years) undergoing major abdominal surgery at our institution between April 2022 to January 2023 were prospectively enrolled. Frailty was evaluated with FRAIL, mFI-5 and GFI before operation. Data on demographics, comorbidities, perioperative management, postoperative recovery of bowel function and PPOI occurrence were collected.

RESULTS

The incidence of frailty assessed with FRAIL, mFI-5 and GFI was 18.2%, 38.4% and 32.5% in a total of 203 patients, respectively. Ninety-five (46.8%) patients experienced PPOI. Time to first soft diet intake was longer in patients with frailty assessed by the three scales than that in patients without frailty. Frailty diagnosed by mFI-5 [Odds ratio (OR) 3.230, 95% confidence interval (CI) 1.572-6.638, P = 0.001] or GFI (OR 2.627, 95% CI 1.307-5.281, P = 0.007) was related to a higher risk of PPOI. Both mFI-5 [Area under curve (AUC) 0.653, 95% CI 0.577-0.730] and GFI (OR 2.627, 95% CI 1.307-5.281, P = 0.007) had insufficient accuracy for the prediction of PPOI in patients undergoing major abdominal surgery.

CONCLUSIONS

Elderly patients diagnosed as frail on the mFI-5 or GFI are at an increased risk of PPOI after major abdominal surgery. However, neither mFI-5 nor GFI can accurately identify individuals who will develop PPOI.

Comparison of laparoscopic and open inguinal-hernia repair in elderly patients: the experience of two comprehensive medical centers over 10 years

PURPOSE

The safety of laparoscopic inguinal-hernia repair must be carefully evaluated in elderly patients. Very little is known regarding the safety of the laparoscopic approach in elderly patients under surgical and medical co-management (SMC). Therefore, this study evaluated the safety of the laparoscopic approach in elderly patients, especially patients with multiple comorbidities under SMC.

METHODS

From January 2012 to December 2021, patients aged ≥ 65 years who underwent open or laparoscopic inguinal-hernia repair during hospitalization were consecutively enrolled. Postoperative outcomes included major and minor operation-related complications, and other adverse events. To reduce potential selection bias, propensity score matching was performed between open and laparoscopic groups based on patients' demographics and comorbidities.

RESULTS

A total of 447 elderly patients who underwent inguinal-hernia repair were enrolled, with 408 (91.3%) underwent open and 39 (8.7%) laparoscopic surgery. All postoperative outcomes were comparable between open and laparoscopic groups after 1:1 propensity score matching (all p > 0.05). Moreover, compared to the traditional care group (n = 360), a higher proportion of the SMC group (n = 87) was treated via the laparoscopic approach (18.4% vs. 6.4%, p = 0.00). In the laparoscopic approach subgroup (n = 39), patients in the SMC group (n = 16) were older with multiple comorbidities but were at higher risks of only minor operation-related complications, compared to those in the traditional care group.

CONCLUSIONS

Laparoscopic inguinal-hernia repair surgery is safe for elderly patients, especially those with multiple comorbidities under SMC.

Geriatric Assessment in Colorectal Surgery: A Systematic Review

INTRODUCTION

The prevalence of colorectal surgery among older adults is expected to rise due to the aging population. Geriatric conditions (e.g., frailty) are risk factors for poor surgical outcomes. The goal of this systematic review is to examine how current literature describes geriatric assessment interventions in colorectal surgery and associated outcomes.

METHODS

Systematic searches of Ovid MEDLINE, Cochrane Library, CINAHL, Embase, and Web of Science were completed. Review was performed according to Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines and prospectively registered in PROSPERO, the international prospective register of systematic reviews in health and social care. All cohort studies and randomized trials of adult colorectal surgery patients where geriatric assessment was performed were included. Geriatric assessment with/without management interventions were identified and described.

RESULTS

Seven-hundred ninety-three studies were identified. Duplicates (197) were removed. An additional 525 were excluded after title/abstract review. After full-text review, 20 studies met the criteria. Reference list review increased final total to 25 studies. All 25 studies were cohort studies. No randomized clinical trials were identified. Heterogeneous assessments were organized into geriatrics domains (mind, mobility, medications, matters most, and multi-complexity). Incomplete evaluations across geriatric domains were performed with few studies describing the use of assessments to impact management decisions.

CONCLUSIONS

There are no randomized trials assessing the impact of geriatric assessment to tailor management strategies and improve outcomes in colorectal surgery. Few studies performed assessments to evaluate the geriatric domain matters most. These findings represent a gap in evidence for the efficacy of geriatric assessment and management strategies in colorectal surgical care.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSION

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

Modified Frailty Index Predicts Postoperative Complications Following Parastomal Hernia Repair

BACKGROUND

The 5-factor frailty index (5-mFI), validated frailty index with Spearmen rho correlation of .95 and C statistic >.7 for predicting postoperative complications, can be preoperatively used to stratify patients prior to parastomal hernia repairs.

METHODS

Retrospective review of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database identified patients from 2015 to 2020. 5-mFI scores were calculated by adding one point for each comorbidity present: diabetes mellitus, congestive heart failure (CHF), hypertension requiring medication, severe chronic obstructive pulmonary disease (COPD), non-independent functional status. Primary endpoint was 30-day overall complications; secondary endpoints were 30-day readmission, reoperation, and discharge to care facility.

RESULTS

2924 (52.2% female) patients underwent elective parastomal hernia repair. Univariate analysis showed 5-mFI > 2 had higher rates of overall (P = .008), pulmonary (P = .002), cardiovascular (P = .003)), hematologic (P = .003), and renal (P = .002) complications and higher rates of readmission (P = .009), reoperation (P = .001), discharge to care facility (P < .001), and death (P < .001). Multivariate analysis identified a 5-mFI of 2 or more as an independent risk factor for overall complications [OR: 1.40, 1.03-1.78; P = .032], pulmonary complications [2.97, 1.63-5.39; P < .001], hematological complications [1.60, 1.03-2.47; P = .035], renal complications [2.04, 1.19-3.46; P = .009], readmission [1.54, 1.19-1.99; P < .001], and discharge to facility [2.50, 1.66-3.77; P < .001]. Reoperation was not signification on multivariate analysis.

CONCLUSIONS

Parastomal hernia repair patients with 5-mFI score of >2 had higher risk of renal, cardiovascular, pulmonary, and hematologic complications, readmissions, longer hospitalization, discharge to care facility, and mortality, and can be useful during preoperative risk stratification.

Chart-Derived Frailty Index and 90-Day Mortality After Burn Surgery

INTRODUCTION

Frailty is a reduced physiological reserve condition associated with postoperative morbidity and mortality. The chart-derived frailty index (CFI) can measure frailty using demographic and laboratory values. We evaluated the association of preoperative CFI with 90-d mortality after burn surgery.

METHODS

This large retrospective study included burn intensive care unit (ICU) patients between 2012 and 2021 and calculated CFI using the sum of the following five variables: age >70 y, body mass index <18.5 kg/m2, hematocrit <35%, albumin <3.4 g/dL, and creatinine >2.0 mg/dL; high CFI was a score of 3-5. Postoperative 90-d mortality rate, major adverse cardiac events (MACE), pneumonia, continuous renal replacement therapy (CRRT) requirement, and prolonged ICU stay (>60 d) were evaluated.

RESULTS

Of 1118 patients, 147 (13.1%) had high CFI. High CFI patients had a higher 90-d mortality rate than did low CFI patients (38.8% versus 22.6%, P < 0.001). A high CFI was significantly associated with postoperative 90-d mortality (hazard ratio = 4.124, 95% confidence interval = 2.980-5.707, P < 0.001) in multivariate Cox regression analysis. Kaplan-Meier analysis revealed significantly different postoperative 90-d mortality rates between patients with high and low CFIs (log-rank test, P < 0.001). Incidences of postoperative MACE, pneumonia, the need for CRRT, and prolonged ICU stay were significantly higher in patients with high CFIs than in those with low CFIs.

CONCLUSIONS

Preoperative high CFI was associated with increased 90-d mortality, MACE, pneumonia, CRRT requirement, and ICU stay following burn surgery.

Impact of functional status on 30-day resource utilization and organ system complications following index bariatric surgery: a cohort study

BACKGROUND

Bariatric surgical procedures carry an appreciable risk profile despite their elective nature. Identified risk factors for procedural complications are often limited to medical comorbidities. This study assesses the impact of functional status on resource utilization and organ system complications following bariatric surgery.

MATERIALS AND METHODS

This retrospective cohort study analyzed patients undergoing elective, index bariatric surgery from American College of Surgeons National Surgical Quality Improvement Program participating hospitals from 2015 to 2019 ( n =65 627). The primary independent variable was functional status. The primary outcome was unplanned resource utilization. Secondary outcomes included composite organ system complications and mortality. The impact of functional status was first investigated with univariate analyses. Survival and multivariate analyses were then performed on select complications with clinically and statistically significant incidence in the dependent cohort.

RESULTS

On univariate analysis, dependent functional status was associated with unplanned resource utilization [12.1% (27/223) vs. 4.1% (2661/65 404)]; relative risk, 2.98 (95% CI, 2.09-4.25); P < 0.001] and haematologic/infectious complications [6.7% (15/223) vs. 2.4% (1540/65 404); relative risk, 2.86 (95% CI, 1.75-4.67); P < 0.001]. Survival analysis demonstrated a significantly shorter time to both events in patients with dependent functional status ( P < 0.001). On multivariate analysis, dependent functional status was an independent predictor of unplanned resource utilization[adjusted odds ratio 2.17 (95% CI, 1.27-3.50); P = 0.003; model c-statistic, 0.572]) and haematologic/infectious complications [adjusted odds ratio, 2.20 ([95% CI, 1.14-3.86); P = 0.011; model c-statistic, 0.579].

CONCLUSION

Patients with dependent functional status are at an elevated risk of unplanned resource utilization and haematologic/infectious complications following index bariatric surgery. The increased risk cannot be explained by medical comorbidities alone.

Frail but Resilient: Frailty in Autologous Breast Reconstruction is Associated with Worse Surgical Outcomes but Equivalent Long-Term Patient-Reported Outcomes

BACKGROUND

Frailty is associated with higher risk of complications following breast reconstruction, but its impact on long-term surgical and patient-reported outcomes has not been investigated. We examined the association of the five-item modified frailty index (MFI) score with long-term surgical and patient-reported outcomes in autologous breast reconstruction.

PATIENTS AND METHODS

We conducted a retrospective cohort study of consecutive patients who underwent mastectomy and autologous breast reconstruction between January 2016 and April 2022. Primary outcome was any flap-related complication. Secondary outcomes were patient-reported outcomes and predictors of complications in the frail cohort.

RESULTS

We identified 1640 reconstructions (mean follow-up 24.2 ± 19.2 months). In patients with MFI ≥ 2, the odds of surgical [odds ratio (OR) 2.13, p = 0.023] and medical (OR 17.02, p < 0.001) complications were higher than in nonfrail patients. We found no significant difference in satisfaction with the breast (p = 0.287), psychosocial well-being (p = 0.119), or sexual well-being (p = 0.314) according to MFI score. Chronic obstructive pulmonary disease was an independent predictor of infection (OR 3.70, p = 0.002). Tobacco use (OR 7.13, p = 0.002) and contralateral prophylactic mastectomy (OR 2.36, p = 0.014) were independent predictors of wound dehiscence. Dependent functional status (OR 2.36, p = 0.007) and immediate reconstruction (compared with delayed reconstruction; OR 3.16, p = 0.026) were independent predictors of skin flap necrosis. Dependent functional status was also independently associated with higher odds of reoperation (OR 2.64, p = 0.011).

CONCLUSION

Frailty is associated with higher risk of complications in breast reconstruction, but there is no significant difference in long-term patient-reported outcomes. MFI should be considered in breast reconstruction to improve outcomes in high-risk frail patients.

Healthcare delivery to elderly and unfit patients with breast disease and comorbidities under an outpatient regime: A report of a personal surgical technique named "Cut&Sew"

Introduction

A growing need for proper geriatric assessment and short-stay surgical programs supported by the availability of less invasive approaches, even in ambulatory settings, is being recognized as a feasible option for breast cancer patients with comorbidities who are usually distressed after standard surgery with ordinary hospitalization. Few studies have been conducted in Italian breast centers with dedicated techniques and approach for frail patients with breast diseases due to a jeopardized approach to ambulatory surgery among institutions.

Methods

This study included 58 women diagnosed with breast disease and comorbidities between March 2019 and December 2022 at the Ambulatory of Senology of San Giacomo Hospital in Novi Ligure (AL, Italy) and Civil Hospital in Ovada (AL, Italy). The patients were evaluated by a multidisciplinary consensus according to the guidelines provided to limit sentinel lymph node biopsy (SLNB) in older women. This kind of ambulatory surgery technique has been designed for i) patients with advanced age and/or comorbidities, ii) frail patients who psychologically do not accept other kinds of surgery, iii) patients who do not require SLNB, and iv) patients who need a surgical biopsy for lesions classified as B3 or small lesions with dubious radiological imaging. With this technique, the quadrant and whole breast may be removed in an outpatient setting with local anesthesia to limit blood loss by immediately cutting and suturing small portions of the gland. Local anesthetic infiltration is sequential and occurs stepwise before providing short passages of approximately 2 cm during resection and immediately suturing the surgical wound. This overclock technique, named "Cut&Sew," requires no more than 20-25 min and allows for a 1-2 h patient discharge with no drainage. The follow-up period was set at 60 months during routine yearly visits.

Results

The patients were older or super-older with most primary pT1/pT2 tumors and ductal type cancers, which were distributed in molecular subtypes Luminal A (37.1 %) and Luminal B (41.5 % Luminal B, with 11.2 % being HER2 positive). The tumour grade was mostly G2-G3. Mastectomy was performed in 10 patients, whereas quadrantectomy was performed in 48 patients, with the majority of tumors localized in Q1.While accompanied by a relative or a caregiver, all 58 patients acceded the "Cut&Sew" surgical technique in an ambulatory setting reporting negligible pain during the surgery and no pain within 10 days post-surgery. No post-operative complications or readmissions were recorded, and no discomfort or recurrence was detected during scheduled visits. Finally, the extent of satisfaction with the overall surgery was recorded immediately and corroborated by most patients during the follow-up period.

Conclusions

Although the small volume of cases collected does not allow for a controlled study necessary to evaluate the safety and efficacy of this technique for approaching frail and older women with comorbidities, through the "Cut&Sew" surgical technique, frail, older, and super older patients may benefit from a minimal psychological impact of surgery, while improving the patients' disease-free life so to corroborate the advised surgical de-escalation but avoiding undertreatment for this kind of patient category. Moreover, a stricter assessment of patient pain and overall satisfaction with the collection of a larger amount of reliable data could allow this technique to be extended to frail and/or older patients as a valuable and safe alternative to the more common hospitalization with general anesthesia. Other advantages include reduced hospitalization costs for sanitary structures.

Automated Electronic Frailty Index is Associated with Non-home Discharge in Patients Undergoing Open Revascularization for Peripheral Vascular Disease

BACKGROUND

Frailty is associated with adverse surgical outcomes including post-operative complications, needs for post-acute care, and mortality. While multiple frailty screening tools exist, most are time and resource intensive. Here we examine the association of an automated electronic frailty index (eFI), derived from routine data in the Electronic Health Record (EHR), with outcomes in vascular surgery patients undergoing open, lower extremity revascularization.

METHODS

A retrospective analysis at a single academic medical center from 2015 to 2019 was completed. Information extracted from the EHR included demographics, eFI, comorbidity, and procedure type. Frailty status was defined as fit (eFI≤0.10), pre-frail (0.100.21). Outcomes included length of stay (LOS), 30-day readmission, and non-home discharge.

RESULTS

We included 295 patients (mean age 65.9 years; 31% female), with the majority classified as pre-frail (57%) or frail (32%). Frail patients exhibited a higher degree of comorbidity and were more likely to be classified as American Society of Anesthesiologist class IV (frail: 46%, pre-frail: 27%, and fit: 18%, P = 0.0012). There were no statistically significant differences in procedure type, LOS, or 30-day readmissions based on eFI. Frail patients were more likely to expire in the hospital or be discharged to an acute care facility (31%) compared to pre-frail (14%) and fit patients (15%, P = 0.002). Adjusting for comorbidity, risk of non-home discharge was higher comparing frail to pre-frail patients (OR 3.01, 95% CI 1.40-6.48).

DISCUSSION

Frail patients, based on eFI, undergoing elective, open, lower extremity revascularization were twice as likely to not be discharged home.

Frailty as a Predictor of Outcomes in Subarachnoid Hemorrhage: A Systematic Review and Meta-Analysis

Frailty is an emerging concept in clinical practice used to predict outcomes and dictate treatment algorithms. Frail patients, especially older adults, are at higher risk for adverse outcomes. Aneurysmal subarachnoid hemorrhage (aSAH) is a neurosurgical emergency associated with high morbidity and mortality rates that have previously been shown to correlate with frailty. However, the relationship between treatment selection and post-treatment outcomes in frail aSAH patients is not established. We conducted a meta-analysis of the relevant literature in accordance with PRISMA guidelines. We searched PubMed, Embase, Web of Science, and Google Scholar using "Subarachnoid hemorrhage AND frailty" and "subarachnoid hemorrhage AND frail" as search terms. Data on cohort age, frailty measurements, clinical grading systems, and post-treatment outcomes were extracted. Of 74 studies identified, four studies were included, with a total of 64,668 patients. Percent frailty was 30.4% under a random-effects model in all aSAH patients (p < 0.001). Overall mortality rate of aSAH patients was 11.7% when using a random-effects model (p < 0.001). There was no significant difference in mortality rate between frail and non-frail aSAH patients, but this analysis only included two studies and should be interpreted cautiously. Age and clinical grading, rather than frailty, independently predicted outcomes and mortality in aSAH patients.

Ventral hernia repair with concurrent intra-abdominal surgery: Results from an eleven-year population-based cohort in Sweden

BACKGROUND

One remaining question in ventral hernia repair is whether to perform concurrent abdominal surgery or plan two-stage procedures. The aim was to explore the risk for reoperation and mortality due to surgical complication during index admission.

METHOD

Eleven-year data were retrieved from the National Patient Register and 68,058 primary surgical admissions were included, divided into minor and major hernia surgery and concurrent abdominal surgery. Results were evaluated by logistic regression analysis.

RESULTS

The risk for reoperation during index admission was higher for patients with concurrent surgery. Major hernia surgery and major concurrent surgery had an OR 37.9 compared to major hernia surgery only. Mortality rate within 30 days increased, OR 9.32. The combined risk for serious adverse event was accumulative.

CONCLUSION

These results stress the importance of critically evaluating needs for and planning of concurrent abdominal surgery during ventral hernia repair. Reoperation rate was a valid and useful outcome variable.

Patient selection in ambulatory surgery

Patient selection is important for ambulatory surgical practices. Proper patient selection for ambulatory practices will optimize resources and lead to increased patient and provider satisfaction. As the number and complexity of procedures in ambulatory surgical centers increase, it is important to ensure that patients are best cared for in facilities that can provide appropriate levels of care. This review addresses the multiple variables and resources that should be considered when selecting patients for anesthesia in ambulatory centers and offices.

Impact of Prehabilitation on Postoperative Mortality and the Need for Non-Home Discharge in High-Risk Surgical Patients

BACKGROUND

The preoperative period is an important target for interventions (eg Surgical Prehabilitation and Readiness [SPAR]) that can improve postoperative outcomes for older patients with comorbidities.

STUDY DESIGN

To determine whether a preoperative multidisciplinary prehabilitation program (SPAR) reduces postoperative 30-day mortality and the need for non-home discharge in high-risk surgical patients, surgical patients enrolled in a prehabilitation program targeting physical activity, pulmonary function, nutrition, and mindfulness were compared with historical control patients from 1 institution's American College of Surgeons (ACS) NSQIP database. SPAR patients were propensity score-matched 1:3 to pre-SPAR NSQIP patients, and their outcomes were compared. The ACS NSQIP Surgical Risk Calculator was used to compare observed-to-expected ratios for postoperative outcomes.

RESULTS

A total of 246 patients were enrolled in SPAR. A 6-month compliance audit revealed that overall patient adherence to the SPAR program was 89%. At the time of analysis, 118 SPAR patients underwent surgery with 30 days of follow-up. Compared with pre-SPAR NSQIP patients (n = 4,028), SPAR patients were significantly older with worse functional status and more comorbidities. Compared with propensity score-matched pre-SPAR NSQIP patients, SPAR patients had significantly decreased 30-day mortality (0% vs 4.1%, p = 0.036) and decreased need for discharge to postacute care facilities (6.5% vs 15.9%, p = 0.014). Similarly, SPAR patients exhibited decreased observed 30-day mortality (observed-to-expected ratio 0.41) and need for discharge to a facility (observed-to-expected ratio 0.56) compared with their expected outcomes using the ACS NSQIP Surgical Risk Calculator.

CONCLUSIONS

The SPAR program is safe and feasible and may reduce postoperative mortality and the need for discharge to postacute care facilities in high-risk surgical patients.

Preoperative risk factors and postoperative complications associated with mortality after outpatient surgery in a broad surgical population: an analysis of 2.8 million ACS-NSQIP patients

BACKGROUND

Thirty-day mortality after outpatient surgery is unexpected and undesired. We investigated preoperative risk factors, operative variables, and postoperative complications associated with 30-day death after outpatient surgery.

METHODS

Using the 2005 to 2018 American College of Surgeons National Surgical Quality Improvement Program database, we evaluated 30-day mortality rate trends over time after outpatient operations. We analyzed associations between 37 preoperative variables, operation time, hospital length of stay, and 9 postoperative complications with mortality rate using χ2 analyses for categorical data and tests for continuous data. We used forward selection logistic regression models to determine the best predictors of mortality preoperatively and postoperatively. We also separately analyzed mortality by age group.

RESULTS

A total of 2,822,789 patients were included. The 30-day mortality rate did not change significantly over time (P = .34, Cochran-Armitage trend test), remaining steady at around 0.06%. The most significant preoperative predictors of mortality included the patient having disseminated cancer, decreased functional health status, increased American Society of Anesthesiology Physical Status classification, increased age, and ascites, accounting for 95.8% (0.837/0.874) of the full model c-index. The most significant postoperative complications associated with increased risk of mortality included having cardiac (26.95% yes vs 0.04% no), pulmonary (10.25% vs 0.04%), stroke (9.22% vs 0.06%), and renal (9.33% vs 0.06%) complications. Postoperative complications conferred a greater risk for mortality than preoperative variables. Mortality risk increased incrementally with age, particularly past age 80.

CONCLUSION

The operative mortality rate after outpatient surgery has not changed over time. Patients over 80 years with disseminated cancer, decreased functional health status, or increased ASA class should generally be considered for inpatient surgery. However, there might be some circumstances where outpatient surgery could be considered.

Palliative Gastrectomy Improves the Survival of Patients with Metastatic Early-Onset Gastric Cancer: A Retrospective Cohort Study

Background: Recent studies have found that patients with incurable gastric cancer might benefit from palliative gastrectomy, but the impact of palliative gastrectomy on metastatic early-onset gastric cancer (mEOGC) patients remains unclear. Methods: We analyzed mEOGC patients enrolled in the Surveillance, Epidemiology, and End Results registry from January 2004 to December 2018. Propensity score matching (PSM) analysis with 1:1 matching and the nearest-neighbor matching method were used to ensure well-balanced characteristics between the groups of patients with palliative gastrectomy and those without surgery. Kaplan-Meier survival analysis and Cox proportional hazards regression models were used to evaluate the overall survival (OS) and cause-specific survival (CSS) risk with corresponding 95% confidence intervals (CIs). Results: Of 3641 mEOGC patients, 442 (12.1%) received palliative gastrectomy. After PSM, 596 patients were included in the analysis, with 298 in each group. For the matched cohort, the median survival was 8 months, and the 5-year survival was 4.0%. The median OS of mEOGC patients undergoing palliative gastrectomy was significantly longer than that of patients without surgery (13 months vs. 6 months, p < 0.001), and palliative gastrectomy remained an independent protective factor after adjusting for confounders (HR 0.459, 95% CI 0.382-0.552, p < 0.001), and the protective effect was robust in the subgroup analysis. Similar results were indicated in CSS. Stratified analyses by treatment modality also warranted the superiority of palliative-gastrectomy-based treatment in improving OS and CSS. Conclusions: mEOGC patients with palliative gastrectomy had a significantly longer survival time than patients without surgery. Exploratory analysis confirmed that surgery-based therapy modality was superior in improving survival time.

Efficacy of the Modified 5-Item Frailty Index in Predicting Surgical-Site Infections in Patients Undergoing Breast Implant Augmentation: A National Surgical Quality Improvement Project-Based 5-Year Study

Background

The ability to predict breast implant augmentation complications can significantly inform patient management. A frailty measure, such as the modified 5-item frailty index (mFI-5), is becoming an increasingly established risk factor for adverse postoperative outcomes. The authors hypothesized that the mFI-5 is predictive of 30-day postoperative complications in breast augmentation.

Objectives

To investigate if mFI-5 can predict the likelihood and magnitude of 30-day complications resulting from breast augmentations.

Methods

A retrospective review study of the National Surgical Quality Improvement Program database for patients who underwent breast implant augmentation without other concurrent procedures, from 2015 to 2019. Age, BMI, number of major comorbidities, American Society of Anesthesiologists (ASA) classifications, smoking status, mFI-5 score, and modified Charlson comorbidity index score were compared as predictors of all-cause 30-day complications and 30-day surgical-site complications using regression analyses.

Results

Overall, 2478 patients were analyzed, and among them, 53 patients developed complications (2.14%). mFI-5 score significantly predicted surgical-site infection (SSI) complications (odds ratio [OR] = 4.24, P = .026). Frail patients had a higher occurrence of SSIs than nonfrail patients (P = .049). Multivariable analyses showed ASA class predicted 30-day SSI complications (OR = 5.77, P = .027) and mFI-5 approached, but did not reach full significance in predicting overall 30-day complications (OR = 3.14, P = .085).

Conclusions

To date, the impact of frailty on breast implant procedure outcomes has not been studied. Our analysis demonstrates that the mFI-5 is a significant predictor for SSIs in breast implant augmentation surgery and is associated with overall complications. By preoperatively identifying frail patients, the surgical team can better account for postoperative support to minimize the risk of complications.

The impact of frailty on ventral hernia repair outcomes in a statewide database

INTRODUCTION

Preoperative frailty is a strong predictor of postoperative morbidity in the general surgery population. Despite this, there are a paucity of research examining the effect of frailty on outcomes after ventral hernia repair (VHR), one of the most common abdominal operations in the USA. We examined the association of frailty with short-term postoperative outcomes while accounting for differences in preoperative, operative, and hernia characteristics.

METHODS

We retrospectively reviewed the Michigan Surgery Quality Collaborative Hernia Registry (MSQC-HR) for adult patients who underwent VHR between January 2020 and January 2022. Patient frailty was assessed using the validated 5-factor modified frailty index (mFI5) and categorized as follows: no (mFI5 = 0), moderate (mFI5 = 1), and severe frailty (mFI5 ≥ 2). Our primary outcome was any 30-day complication. Multivariable logistic regression was used to evaluate the association of frailty with outcomes while controlling for patient, operative, and hernia variables.

RESULTS

A total of 4406 patients underwent VHR with a mean age (SD) of 55 (15) years, 2015 (46%) females, and 3591 (82%) white patients. The mean (SD) BMI of the cohort was 33 (8) kg/m2. A total of 2077 (47%) patients had no frailty, 1604 (36%) were moderately frail, and 725 (17%) were severely frail. The median hernia size (interquartile range) was 2.5 cm (1.5-4.0 cm). Severe frailty was associated with increased odds of any complication (adjusted Odds Ratio (aOR) 3.12, 95% CI 1.78-5.47), serious complication (aOR 5.25, 95% CI 2.17-13.19), SSI (aOR 3.41, 95% CI 1.58-7.34), and post-discharge adverse events (aOR 1.70, 95% CI 1.24-2.33).

CONCLUSION

After controlling for patient, operative, and hernia characteristics, frailty was independently associated with increased odds of postoperative complications. These findings highlight the importance of preoperative frailty assessment for risk stratification and to inform patient counseling.

Operative Management of Thyroid Disease in Older Adults

As the population ages, both domestically and globally, clinicians will increasingly find themselves navigating treatment decisions for thyroid disease in older adults. When considering surgical treatment, individualizing risk assessment is particularly important, as older patients can present with very different health profiles. While fit, independent individuals may benefit from thyroidectomy with minimal risk, those with multiple comorbidities and poor functional status are at higher risk of perioperative complications, which can have adverse health effects and detract from long-term quality of life. In order to optimize surgical outcomes for older adults, strategies for accurate risk assessment and mitigation are being explored. Surgical decision-making also should consider the characteristics of the thyroid disease being treated, given many benign thyroid disorders and some well-differentiated thyroid cancers can be appropriately managed nonoperatively without compromising longevity. Shared decision-making becomes increasingly important to respect the health priorities and optimize outcomes for older adults with thyroid disease. This review summarizes the current knowledge of thyroid surgery in older adults to help inform decision-making among patients and their physicians.

Is surgical resection predict overall survival in frail patients with glioblastoma, IDH-wildtype?

PURPOSE

We assessed the impact of frailty on surgical outcomes, survival, and functional dependency in elderly patients harboring a glioblastoma, isocitrate dehydrogenase (IDH)-wildtype.

METHODS

We retrospectively reviewed records of old and frail patients surgical treated at a single neurosurgical institution between January 2018 to May 2021. Inclusion criteria were: (1) neuropathological diagnosis of glioblastoma, IDH-wildtype; (2) patient≥65years at the time of surgery; (3) available data to assess the frailty index according to the 5-modified Frailty Index (5-mFI).

RESULTS

A total of 47 patients were included. The 5-mFI was at 0 in 11 cases (23.4%), at 1 in 30 cases (63.8%), at 2 in two cases (4.2%), at 3 in two cases (4.2%), and at 4 in two cases (4.2%). A gross total resection was performed in 26 patients (55.3%), a subtotal resection was performed in 13 patients (27.6%), and a biopsy was performed in 8 patients (17.1%). The rate of 30-day postoperative complications was higher in the biopsy subgroup and in the 5-mFI=4 subgroup. Gross total resection and age≤70years were independent predictors of a longer overall survival. Sex, 5-mFI, postoperative complications, and preoperative Karnofsky Performance Status score did not influence overall survival and functional dependency.

CONCLUSION

In patients≥65years harboring a glioblastoma, IDH-wildtype, gross total resection remains an independent predictor of longer survival and good postoperative functional recovery. The frailty, assessed by the 5-mFI score, does not influence surgery and outcomes in this dataset. Further confirmatory analyses are required.

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.

Chronologic Age, Independent of Frailty, is the Strongest Predictor of Failure-to-Rescue After Surgery for Gastrointestinal Malignancies

BACKGROUND

Prior studies of older cancer patients undergoing large operations have reported similar rates of complications to the general population but higher rates of mortality, suggesting higher rates of failure-to-rescue (FTR) with advanced age. Whether age is a marker for frailty, or an independent predictor of FTR, is not clear.

METHODS

The ACS-NSQIP database was queried from 2015-19 for patients undergoing surgery for gastrointestinal (GI) malignancy. Patients were divided into age-stratified cohorts: C1 (18-55), C2 (56-65), C3 (66-75), C4 (76-89). Adjusted odds ratios (aOR) were computed to assess the relationship of the FTR rate and age, while controlling for potential confounders. A second analysis was specified with all covariates converted to Z-scores, which generated scaled adjusted odds ratios (saOR) to determine the strongest predictor of FTR.

RESULTS

Multivariable analysis suggests that age is an independent predictor of FTR: C2:C1 aOR = 1.87 (p < 0.001); C3:C1 aOR = 3.33 (p < 0.001); C4:C1 aOR = 5.71 (p < 0.001). The scaled analysis demonstrated that age is the strongest predictor of FTR (saOR = 1.92, p < 0.001); a one standard deviation increase in age was associated with a 92% increased odds of FTR. The saOR for frailty (1.18, p < 0.001) and for number of comorbidities (1.10, p = 0.005) also were statistically significant.

CONCLUSIONS

Chronologic age was independently associated with increased FTR after surgery for GI malignancy and was the strongest predictor of FTR. These results suggest that chronologic age must be carefully considered when evaluating the fitness of a patient for GI cancer surgery.

Sex-Related Differences in Acuity and Postoperative Complications, Mortality and Failure to Rescue

INTRODUCTION

Yentl syndrome describing sex-related disparities has been extensively studied in medical conditions but not after surgery. This retrospective cohort study assessed the association of sex, frailty, presenting with preoperative acute serious conditions (PASC), and the expanded Operative Stress Score (OSS) with postoperative complications, mortality, and failure-to-rescue.

METHODS

The National Surgical Quality Improvement Program from 2015 to 2019 evaluating 30-d complications, mortality, and failure-to-rescue.

RESULTS

Of 4,860,308 cases (43% were male; mean [standard deviation] age of 56 [17] y), 6.0 and 0.8% were frail and very frail, respectively. Frailty score distribution was higher in men versus women (P < 0.001). Most cases were low-stress OSS2 (44.9%) or moderate-stress OSS3 (44.5%) surgeries. While unadjusted 30-d mortality rates were higher (P < 0.001) in males (1.1%) versus females (0.8%), males had lower odds of mortality (adjusted odds ratio (aOR) = 0.92, 95% confidence interval [CI] = 0.90-0.94, P < 0.001) after adjusting for frailty, OSS, case status, PASC, and Clavien-Dindo IV (CDIV) complications. Males have higher odds of PASC (aOR = 1.33, CI = 1.31-1.35, P < 0.001) and CDIV complications (aOR = 1.13, CI = 1.12-1.15, P < 0.001). Male-PASC (aOR = 0.76, CI = 0.72-0.80, P < 0.001) and male-CDIV (aOR = 0.87, CI = 0.83-0.91, P < 0.001) interaction terms demonstrated that the increased odds of mortality associated with PASC or CDIV complications/failure-to-rescue were lower in males versus females.

CONCLUSIONS

Our study provides a comprehensive analysis of sex-related surgical outcomes across a wide range of procedures and health care systems. Females presenting with PASC or experiencing CDIV complications had higher odds of mortality/failure to rescue suggesting sex-related care differences. Yentl syndrome may be present in surgical patients; possibly related to differences in presenting symptoms, patient care preferences, or less aggressive care in female patients and deserves further study.

Association of Frailty and the Expanded Operative Stress Score with Preoperative Acute Serious Conditions, Complications, and Mortality in Males Compared to Females: A Retrospective Observational Study

OBJECTIVE

The aim of this study was to expand Operative Stress Score (OSS) increasing procedural coverage and assessing OSS and frailty association with Preoperative Acute Serious Conditions (PASC), complications and mortality in females versus males.

SUMMARY BACKGROUND DATA

Veterans Affairs male-dominated study showed high mortality in frail veterans even after very low stress surgeries (OSS1).

METHODS

Retrospective cohort using NSQIP data (2013-2019) merged with 180-day postoperative mortality from multiple hospitals to evaluate PASC, 30-day complications and 30-, 90-, and 180-day mortality.

RESULTS

OSS expansion resulted in 98.2% case coverage versus 87.0% using the original. Of 82,269 patients (43.8% male), 7.9% were frail/very frail. Males had higher odds of PASC [adjusted odds ratio (aOR) = 1.31, 95% confidence interval (CI) = 1.21-1.41, P < 0.001] and severe/life-threatening Clavien-Dindo IV (CDIV) complications (aOR = 1.18, 95% CI = 1.09-1.28, P < 0.001). Although mortality rates were higher (all time-points, P < 0.001) in males versus females, mortality was similar after adjusting for frailty, OSS, and case status primarily due to increased male frailty scores. Additional adjustments for PASC and CDIV resulted in a lower odds of mortality in males (30-day, aOR = 0.81, 95% CI = 0.71-0.92, P = 0.002) that was most pronounced for males with PASC compared to females with PASC (30-day, aOR = 0.75, 95% CI = 0.56-0.99, P = 0.04).

CONCLUSIONS

Similar to the male-dominated Veteran population, private sector, frail patients have high likelihood of postoperative mortality, even after low-stress surgeries. Preoperative frailty screening should be performed regardless of magnitude of the procedure. Despite males experiencing higher adjusted odds of PASC and CDIV complications, females with PASC had higher odds of mortality compared to males, suggesting differences in the aggressiveness of care provided to men and women.

Reviewing next of kin regrets in surgical decision-making: cross-sectional analysis of systematically searched literature

BACKGROUND

Decision-making concerning relatives undergoing surgery is challenging. It remains unclear to what extent implicated next of kin eventually regret their decisions and how this regret is assessed. Our aim was to systematically review the literature on decisional regret of next of kin and to describe the assessment tools used and the surgical populations studied.

METHODS

We included interventional or observational, quantitative or qualitative studies reporting the measurement of decisional regret of next of kin concerning relatives undergoing surgery. We searched a variety of databases without restriction on publication year. We assessed the quality of reporting of quantitative studies using the NIH Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies and of qualitative studies using the Critical Appraisal Skills Program Checklist.

RESULTS

Thirteen cross-sectional, five prospective cohorts and five qualitative studies matched our inclusion criteria. In 18 studies (78%), patients were children, in five (22%), young or middle-aged adults. No study included elderly or frail patients. Thirteen studies (57%) used the original Decision Regret Scale which was validated for patients, but not for next of kin. Only 3 of the 18 (17%) quantitative studies and only one of the 4 (25%) qualitative studies were rated as "good" in the quality assessment.

CONCLUSION

None of the retrieved studies used validated tools to assess the decisional regret of next of kin and none of them examined this issue in elderly or frail surgical patients.

Improved Preoperative Risk Assessment Tools Are Needed to Guide Informed Decision Making before Esophagectomy

OBJECTIVE

We sought to evaluate the performance of 2 commonly used prediction models for postoperative morbidity in patients undergoing open and minimally invasive esophagectomy.

SUMMARY BACKGROUND DATA

Patients undergoing esophagectomy have a high risk of postoperative complications. Accurate risk assessment in this cohort is important for informed decision-making.

METHODS

We identified patients who underwent esophagectomy between January 2016 and June 2018 from our prospectively maintained database. Predicted morbidity was calculated using the American College of Surgeons National Surgical Quality Improvement Program Surgical Risk Calculator (SRC) and a 5-factor National Surgical Quality Improvement Programderived frailty index. Performance was evaluated using concordance index (C-index) and calibration curves.

RESULTS

In total, 240 consecutive patients were included for analysis. Most patients (85%) underwent Ivor Lewis esophagectomy. The observed overall complication rate was 39%; the observed serious complication rate was 33%.The SRC did not identify risk of complications in the entire cohort (C-index, 0.553), patients undergoing open esophagectomy (C-index, 0.569), or patients undergoing minimally invasive esophagectomy (C-index, 0.542); calibration curves showed general underestimation. Discrimination of the SRC was lowest for reoperation (C-index, 0.533) and highest for discharge to a facility other than home (C-index, 0.728). Similarly, the frailty index had C-index of 0.513 for discriminating any complication, 0.523 for serious complication, and 0.559 for readmission.

CONCLUSIONS

SRC and frailty index did not adequately predict complications after esophagectomy. Procedure-specific risk-assessment tools are needed to guide shared patient-physician decision-making in this high-risk population.

Major complications and mortality after ventral hernia repair: an eleven-year Swedish nationwide cohort study

BACKGROUND AND AIMS

Ventral hernia repair is one of the most common surgical procedures performed worldwide. Despite the large volume, consensus is lacking regarding indications for repair or choice of surgical method used for reconstruction. The aim of this study was to explore the risk for major complications and mortality in ventral hernia repair using data from a nationwide patient register.

METHOD

Patient data of individuals over 18 years of age who had a ventral hernia procedure between 2004 and 2014 were retrieved from the Patient Register kept by the Swedish National Board of Health and Welfare. After exclusion of patients with concomitant bowel surgery, 45 676 primary surgical admissions were included. Procedures were dichotomised into laparoscopic and open surgery, and stratified for primary and incisional hernias.

RESULTS

A total of 45 676 admissions were analysed. The material comprised 36% (16 670) incisional hernias and 64% (29 006) primary hernias. Women had a higher risk for reoperation during index admission after primary hernia repair (OR 1.84 (1.29-2.62)). Forty-three patients died of complications within 30 days of index surgery. Patients aged 80 years and older had a 2.5 times higher risk for a complication leading to reoperation, and a 12-fold higher mortality risk than patients aged 70-79 years.

CONCLUSION

Age is the dominant mortality risk factor in ventral hernia repair. Laparoscopic surgery was associated with a lower risk for reoperation during index admission. Reoperation seems to be a valid outcome variable, while registration of complications is generally poor in this type of cohort.

The Frailty Phenotype in Older Adults Undergoing Cochlear Implantation

OBJECTIVE

To prospectively evaluate the frailty phenotype in a population of older adults and determine its association with 1) perioperative complications, 2) need for vestibular rehabilitation after surgery, and 3) early speech perception outcomes.

STUDY DESIGN

Prospective cohort study.

SETTING

Tertiary care hospital.

PATIENTS

Adults older than 65 years undergoing cochlear implantation.

INTERVENTIONS

The Fried Frailty Index was used to classify patients as frail, prefrail, or not frail based on five criteria: 1) gait speed, 2) grip strength, 3) unintentional weight loss, 4) weekly physical activity, and 5) self-reported exhaustion.

MAIN OUTCOMES MEASURES

Rates of intraoperative and postoperative complications, postoperative falls, need for vestibular rehabilitation, and early speech perception outcomes.

RESULTS

Forty-six patients were enrolled in this study. Five patients (10.8%) were categorized as frail and 10 (21.7%) as prefrail. The mean ages of frail, prefrail, and not frail patients were 80.9, 78.8, and 77.5, respectively. There were no intraoperative complications among all groups. Three patients required postoperative vestibular rehabilitation; all were not frail. One postoperative fall occurred in a nonfrail individual. Mean (standard deviation) device use times at 3 months in frail, prefrail, and not frail patients were 7.6 (3.5), 11.1 (3.6), and 11.6 (2.9) hours per day, respectively. Consonant-nucleus-consonant word scores 3 months after surgery in frail, prefrail, and not frail patients were 13% (12.2), 44% (19.7), and 51% (22.4), respectively. The median (range) number of missed follow-up visits (surgeon, audiologist, speech language pathologist combined) was 7 (1-10) in frail patients, compared with a median of 3 (0-4) and 2 (0-5) in prefrail and not frail patients.

CONCLUSIONS

Frail patients did not have increased rates of surgical complications, need for vestibular rehabilitation, or postoperative falls. However, frail patients experienced challenges in accessing postoperative care, which may be addressed by using remote programming and rehabilitation.

Association Between Frailty and Time Alive and At Home After Cancer Surgery Among Older Adults: A Population-Based Analysis

BACKGROUND

Although frailty is known to impact short-term postoperative outcomes, its long-term impact is unknown. This study examined the association between frailty and remaining alive and at home after cancer surgery among older adults.

METHODS

Adults aged ≥70 years undergoing cancer resection were included in this population-based retrospective cohort study using linked administrative datasets in Ontario, Canada. The probability of remaining alive and at home in the 5 years after cancer resection was evaluated using Kaplan-Meier methods. Extended Cox regression with time-varying effects examined the association between frailty and remaining alive and at home.

RESULTS

Of 82,037 patients, 6,443 (7.9%) had preoperative frailty. With median follow-up of 47 months (interquartile range, 23-81 months), patients with frailty had a significantly lower probability of remaining alive and at home 5 years after cancer surgery compared with those without frailty (39.1% [95% CI, 37.8%-40.4%] vs 62.5% [95% CI, 62.1%-63.9%]). After adjusting for age, sex, rural living, material deprivation, immigration status, cancer type, surgical procedure intensity, year of surgery, and receipt of perioperative therapy, frailty remained associated with increased hazards of not remaining alive and at home. This increase was highest 31 to 90 days after surgery (hazard ratio [HR], 2.00 [95% CI, 1.78-2.24]) and remained significantly elevated beyond 1 year after surgery (HR, 1.56 [95% CI, 1.48-1.64]). This pattern was observed across cancer sites, including those requiring low-intensity surgery (breast and melanoma).

CONCLUSIONS

Preoperative frailty was independently associated with a decreased probability of remaining alive and at home after cancer surgery among older adults. This relationship persisted over time for all cancer types beyond short-term mortality and the initial postoperative period. Frailty assessment may be useful for all candidates for cancer surgery, and these data can be used when counseling, selecting, and preparing patients for surgery.

Frailty and postoperative urinary tract infection

BACKGROUND

Among older adults, postoperative urinary tract infection is associated with significant harms including increased risk of hospital readmission and perioperative mortality. While risk of urinary tract infection is known to increase with age, the independent association between frailty and postoperative urinary tract infection is unknown. In this study we used 2014-2018 data from the U.S. National Surgical Quality Improvement Program (NSQIP) to investigate whether frailty is an independent risk factor for postoperative urinary tract infection, controlling for age and other relevant confounders.

METHODS

Frailty was assessed using the modified Frailty Index. Postoperative urinary tract infection was defined as any symptomatic urinary tract infection (of the kidneys, ureters, bladder, or urethra) developing within 30 days of the operative procedure. To examine associations between frailty and other specific factors and postoperative urinary tract infection, chi squared tests, students t-tests, and logistic regression modelling were used.

RESULTS

Urinary tract infection was identified after 22,356 of 1,724,042 procedures (1.3%). In a multivariable model controlling for age and other patient and surgical characteristics, the relative odds for urinary tract infection increased significantly with increasing frailty score. For example, compared to a frailty score of 0, the relative odds for urinary tract infection for a frailty score of 3 was 1.50 (95% confidence interval 1.41, 1.60). The relative odds associated with the maximum frailty score (5) was 2.50 (95% confidence interval 1.73, 3.61).

CONCLUSIONS

Frailty is associated with postoperative urinary tract infection, independent of age. Further research should focus on the underlying mechanisms and strategies to mitigate this risk among frail adults.

The revised-risk analysis index as a predictor of major morbidity and mortality in older patients after abdominal surgery: a retrospective cohort study

Background

The revised-Risk Analysis Index (RAI-rev) can accurately predict postoperative mortality risk. However, the association of RAI-rev with composite outcome of major morbidity and mortality (MMM) among older surgical patients is largely unknown. This study investigated the association between RAI-rev and postoperative MMM in older patients undergoing abdominal surgery. It also assessed the predictive value of RAI-rev combined with other preoperative risk factors.

Methods

This retrospective cohort study reviewed the medical records of all patients aged 65 and older who underwent abdominal surgery between January 2018 and December 2019. The primary outcome was the postoperative MMM during hospitalization, and its association with preoperative RAI-rev scores was assessed using multivariable logistic regression analysis. The prediction of postoperative outcomes was used the receiver-operating characteristic curve analysis.

Results

A total of 2225 older patients were analyzed, and 258 (11.6%) developed postoperative MMM. After adjusting for confounders, each unit increase in RAI-rev scores resulted in a 2.3% increase in the MMM risk and a 3.0% increase in the odds of life-threatening complications and mortality (both P < 0.05). The area under the curves (AUCs) of RAI-rev scores in predicting MMM and life-threatening complications and mortality was 0.604 (95% CI: 0.567 to 0.640) and 0.633 (95% CI: 0.592 to 0.675), respectively (both P < 0.001); when the RAI-rev was combined with age, gender, American Society of Anesthesiologists (ASA) classification, operative stress, and urgency status of surgery (emergency or elective), the AUCs were 0.694 (95% CI: 0.659 to 0.729) and 0.739 (95% CI: 0.702 to 0.777), respectively (both P < 0.001).

Conclusions

Higher RAI-rev scores were independently associated with increased risk of MMM. When combined with age, gender, ASA classification, operative stress, and urgency status of surgery, RAI-rev had improved performance in predicting the risk of MMM, particularly the life-threatening complications and mortality.

Radiological Features for Frailty Assessment in Patients Requiring Emergency Laparotomy

Introduction: As the number of elderly patients requiring surgical intervention rises, it is believed that frailty syndrome has a greater impact on perioperative course than on chronological age. The aim of this study was to evaluate the efficacy of various imaging features for frailty assessment in patients undergoing emergency laparotomy. Methods: The study included all patients that qualified for emergency surgery with preoperative CT scans between 2016 and 2020 in the Second Department of General Surgery. Multiple trauma patients were excluded from the analysis. The modified frailty index and brief geriatric assessment were used in the analysis. CT images were reviewed for the assessment of osteopenia, sarcopenia, sarcopenic obesity, renal volume and abdominal aorta calcification rate. Results: A total of 261 patients were included in the analysis. Multivariate logistic regression identified every next ASA class (OR: 4.161, 95%CI: 1.672–10.355, p = 0.002), intraoperative adverse events (OR: 12.397, 95%CI: 2.166–70.969, p = 0.005) and osteopenia (OR: 4.213, 95%CI: 1.235–14.367, p = 0.022) as a risk factor for 30-day mortality. Our study showed that every next ASA class (OR: 1.952, 95%Cl: 1.171–3.256, p = 0.010) and every point of the BGA score (OR: 1.496, 95%Cl: 1.110–2.016, p = 0.008) are risk factors for major complications. Conclusions: Osteopenia was the best parameter for perioperative mortality risk stratification in patients undergoing emergency surgical intervention. Sarcopenia (measured as psoas muscle area), sarcopenic obesity, aortic calcifications and mean kidney volume do not predict poor outcomes in those patients. None of the radiological markers appeared to be useful for the prediction of perioperative morbidity.

Factors Predicting Frailty Among Postoperative Brain Tumor Patients

ABSTRACT

BACKGROUND: Surgical frailty is a condition in which patients are weak with varied recovery of various organ functions after surgery resulting in unpleasant outcomes. Frailty studies have been conducted in several populations with a limited knowledge on postoperative brain tumor patients. This study aimed to examine factors predicting frailty in brain tumor patients after craniotomy. METHODS: This study was a cross-sectional predictive study. The sample included 85 patients who were 18 years or older and underwent craniotomy with tumor removal from 1 university hospital in Bangkok, Thailand, between February and October 2021. Data were analyzed using descriptive statistic, Pearson correlation, and multiple linear regression, which determined significance level at .05. RESULTS: The prevalence of frailty among participants was 50.6%. Postoperative symptom and mood state were positively associated with frailty (r = 0.410 and r = 0.448, respectively; P < .01). Postoperative symptom, mood state, age, tumor type, and income could explain the variance of frailty in brain tumor patients after craniotomy by 40.3% (R2 = 0.403, P < .01). CONCLUSION: Healthcare providers should plan for discharge planning including assessment and develop the intervention for managing postoperative symptoms and psychological symptoms to promote recovery from frailty that generally occurs after brain tumor surgery.

Heath status, frailty, and multimorbidity in patients with emergency general surgery conditions

BACKGROUND

Although nearly 1 million older adults are admitted for emergency general surgery conditions yearly, the extent to which baseline health influences the development and treatment of emergency general surgery conditions is unknown. We evaluated baseline health and older patients with and without emergency general surgery conditions.

METHODS

We used the prospectively collected Medicare Current Beneficiary Survey with Medicare claims and 2 validated health frameworks: (1) Deficit Accumulation Frailty Score and (2) Complex Multimorbidity. Self-reported health and function items were used to derive pre-emergency general surgery conditions Deficit Accumulation Frailty Score and Complex Multimorbidity scores. Deficit Accumulation Frailty Score ranges from 0 (no frailty deficits) to 100 (all possible deficits present). Complex Multimorbidity is a 3-point categorical rank based on the presence of chronic conditions, functional limitations, and geriatric syndromes. Specific survey factors were also examined to determine association with development of emergency general surgery conditions or use of operative management.

RESULTS

Of 54,417 individuals, 1,960 had emergency general surgery conditions (median age 79 [interquartile range 73-84]). Patients with emergency general surgery conditions had significantly higher Deficit Accumulation Frailty Score (19 [interquartile range 11-31] vs 14 [8-24]) and were more likely to be in the most severe Complex Multimorbidity category (38% vs 29%). Emergency general surgery conditions patients had higher proportions of nearly every health category, with the most striking differences in functional limitations. Patients who were treated nonoperatively had the poorest overall baseline health.

CONCLUSION

Patients who developed emergency general surgery conditions had more severe health burden than patients who did not, particularly in functional status. Clinicians must better understand the interaction between baseline health vulnerability and emergency surgical disease to improve prognostication and ensure alignment of patient goals and treatment strategies.

The clinical impact of frailty on the postoperative outcomes of patients undergoing appendectomy: propensity score-matched analysis of 2011-2017 US hospitals

BACKGROUND

The presence of clinical frailty can pose an escalated risk toward surgical outcomes including in cases that involve minimally invasive procedures. Given this premise, we evaluate the effects of frailty on post-appendectomy outcomes using a national in-hospital registry.

METHODS

2011-2017 National Inpatient Sample was used to isolate inpatient appendectomy cases; the population as stratified using Johns Hopkins ACG clinical frailty, expressed as either binary or ternary (prefrailty, frailty, and without frailty) indicators. The controls were matched to frailty-present groups using propensity score matching and compared to various endpoints, including mortality, length of stay (LOS), hospitalization costs, and postoperative complications.

RESULTS

Post-match, there were 11,758 with and without frailty per binary; and 1236 frail, 10,522 pre-frail with respective equal number controls per ternary indicator. Using binary term, frail patients had higher mortality (4.22 vs 1.49% OR 2.92 95%CI 2.45-3.47), LOS (14.3 vs 5.35d p < 0.001), and costs ($160,700 vs $64,141 p < 0.001). In multivariate, frail patients had higher mortality (aOR 2.77 95%CI 2.32-3.31), as well as higher rates of postoperative complications. Using ternary term, frail patients had higher mortality (5.02 vs 2.27% OR 2.28 95%CI 1.45-3.59), LOS (18.9 vs 5.66 day p < 0.001) and costs ($200,517 vs $66,193 p < 0.001). In multivariate, frail patients had higher mortality (aOR 2.16 95%CI 1.35-3.43) and complications. Those with pre-frailty had higher mortality (4.12 vs 1.47% OR 2.88 95%CI 2.39-3.46), LOS (13.8 vs 5.34 day p < 0.001) and costs ($156,022 vs $63,772 p < 0.001). In multivariate, pre-frailty patients had higher mortality (aOR 2.79 95%CI 2.31-3.37) and complications.

CONCLUSIONS

Frailty and prefrailty (using the ternary indicator) are associated with increased postoperative mortality and complication in patients who undergo appendectomy; given this finding, it is imperative that these vulnerable patients are identified early in the preoperative phase and are provided risk-modifying measures to ameliorate risks and optimize outcomes.

The Utility of the 5-Factor Modified Frailty Index to Predict Postoperative Risk in Microsurgical Reconstruction

BACKGROUND

Microsurgical reconstruction is an integral part of plastic surgery. The 5-factor modified frailty index (5-mFI) is an effective tool to predict postoperative complications across multiple subspecialties. We aimed to determine if frailty scores using the 5-mFI can predict postoperative complications specifically in microvascular reconstruction.

STUDY DESIGN

Frailty scores were retrospectively assessed in microsurgical reconstruction patients (2012-2016) using the American College of Surgeons National Quality Improvement Program base. The 5 variables that comprise the 5-mFI are history of chronic obstructive pulmonary disease, history of congestive heart failure, functional status, hypertension requiring medication and diabetes. The data were analyzed using the Goodman test, χ2 test, and a logistic regression model. The congruence was also compared between the 5-mFI and the American Society of Anesthesiology (ASA) classification in predicting complications.

RESULTS

Of 5894 patients, the highest 5-mFI value was "3." Analyses show an increase in postoperative complications requiring ICU care. Further models indicate an association between readmission with hypertension and chronic obstructive pulmonary disease (P < 0.05). There was an increased risk of a failure to wean from ventilator with a history of chronic obstructive pulmonary disease and diabetes and an increased risk of readmission with a history of hypertension and chronic obstructive pulmonary disease. The 5-mFI and ASA were incongruent in predicting postoperative complications.

CONCLUSIONS

The 5-mFI predicts postoperative complications in the microsurgical reconstruction population. Although the 5-mFI and ASA predict different complications, their use provides insight into the potential adjustable risks before surgery.

Severe functional impairment increases the risk of major morbidity and mortality in older patients after digestive tract surgery: a retrospective cohort study

PURPOSE

The relationship between the severity of impairment in basic activities of daily living (ADLs) function and postoperative outcomes in older surgical patients remains unclear. This study aimed to clarify the association between the severity of preoperative functional impairment and the composite postoperative outcome of major morbidity and mortality in older patients undergoing digestive tract surgery.

METHODS

This was a retrospective cohort study. We collected perioperative data of older patients (age ≥ 65 years) who underwent digestive tract surgery in our institution. The severity of functional impairment was assessed using the Barthel Index scale before surgery. The major morbidity and mortality were defined as Clavien-Dindo grade III or greater postoperative complications during hospital stay. The association between the severity of functional impairment and the major morbidity and mortality was assessed using a multivariable logistic regression model.

RESULTS

131 of 1076 patients (12.2%) developed major morbidity and mortality. After controlling for confounding factors, high Barthel Index scores were correlated with decreased risk of major morbidity and mortality (OR 0.986, 95% CI 0.976-0.997, P = 0.011); preoperative severe (OR 2.862, 95% CI 1.172-6.989, P = 0.021), but not mild or moderate (OR 1.019, 95% CI 0.602-1.726, P = 0.943) functional impairment was independently associated with an increased risk of major morbidity and mortality, when compared with independent functional status.

CONCLUSIONS

Preoperative severe functional impairment in basic ADLs was independently associated with a higher risk of major postoperative morbidity and mortality in older patients undergoing digestive tract surgery.

Increased Morbidity and Mortality After Hepatectomy for Colorectal Liver Metastases in Frail Patients is Largely Driven by Worse Outcomes After Minor Hepatectomy: It's Not "Just a Wedge"

BACKGROUND

Frailty is associated with postoperative mortality, but its significance after hepatectomy for colorectal liver metastases (CRLM) is poorly defined. This study evaluated the impact of frailty after hepatectomy for CRLM.

METHODS

The study identified 8477 patients in National Surgical Quality Improvement Program databases from 2014 to 2019 and stratified them by frailty score using the risk analysis index as very frail (>90th percentile), frail (75th-90th percentile), or non-frail (< 75th percentile). Multivariate regression models determined the impact of frailty on perioperative outcomes, including by the extent of hepatectomy.

RESULTS

The procedures performed were 2752 major hepatectomies (left hepatectomy, right hepatectomy, trisectionectomy) and 5725 minor hepatectomies (≤2 segments) for 870 (10.3%) very frail, 1680 (19.8%) frail, and 5927 (69.9%) non-frail patients. Postoperatively, the very frail and frail patients experienced more complications (very frail [41.8%], frail [35.1%], non-frail [31.0%]), which resulted in a longer hospital stay (very-frail [5.7 days], frail [5.8 days], non-frail [5.1 days]), a higher 30-day mortality (very-frail [2.2%], frail [1.3%], non-frail [0.5%]), and more discharges to a facility (very frail [6.8%], frail [3.7%], non-frail [2.6%]) (p < 0.05) although they underwent similarly extensive (major vs. minor) hepatectomies. In the multivariate analysis, frailty was independently associated with complications (very-frail [odds ratio {OR}, 1.70], frail [OR, 1.25]) and 30-day mortality (very-frail [OR, 4.24], frail [OR, 2.41]) (p < 0.05). After minor hepatectomy, the very frail and frail patients had significantly higher rates of complications and 30-day mortality than the non-frail patients, and in the multivariate analysis, frailty was independently associated with complications (very frail [OR, 1.97], frail [OR, 1.27]) and 30-day mortality (very frail [OR, 6.76], frail [OR, 3.47]) (p < 0.05) after minor hepatectomy.

CONCLUSIONS

Frailty predicted significantly poorer outcomes after hepatectomy for CRLM, even after only a minor hepatectomy.

Association of frailty with outcomes after elective colon resection for diverticular disease

BACKGROUND

Frailty has been associated with greater postoperative morbidity and mortality but its impact has not been investigated in patients with diverticulitis undergoing elective colon resection. Therefore, the present study examined the association of frailty with perioperative outcomes following elective colectomy for diverticular disease.

METHODS

The 2017-2019 American College of Surgeons-National Surgical Quality Improvement Program data registry was queried to identify patients (aged ≥18 years) undergoing elective colon resection for diverticular disease. The 5-factor modified frailty index (mFI-5) was used to stratify patients into non-frail (mFI 0), prefrail (mFI 1), and frail (mFI ≥2) cohorts. Major adverse events, surgical site infection, and postoperative ileus as well as prolonged length of stay, nonhome discharge, and unplanned readmission were evaluated using multivariable logistic models.

RESULTS

Of the 20,966 patients, 10.0% were frail. Compared to others, frail patients were generally older (non-frail: 55 years, [46-63], prefrail: 62, [54-70], frail: 64, [57-71]) and more commonly female (non-frail: 53.1%, prefrail: 58.6, frail: 64.4, P < .001). Frail patients more frequently underwent open colectomy and stoma creation compared with others. Frailty was associated with greater adjusted odds of major adverse event (adjusted odds ratio 1.25, 95% confidence interval 1.06-1.48), surgical site infection (adjusted odds ratio 1.28, 95% confidence interval 1.06-1.54), and postoperative ileus (adjusted odds ratio 1.59, 95% confidence interval 1.27-1.98). Similarly, frailty portended greater odds of prolonged length of stay, nonhome discharge, and unplanned readmission.

CONCLUSION

Frailty as defined by the mFI-5 was associated with greater morbidity and hospital resource use. Deployment of frailty instruments may augment traditional risk calculators and improve patient selection for elective colectomy.
