OBJECTIVE The 5-factor modified frailty index (mFI-5) is a practical tool that can be used to estimate frailty by measuring five accessible factors: functional status, history of diabetes, chronic obstructive pulmonary disease, congestive heart failure, and hypertension. The authors aimed to validate the utility of mFI-5 for predicting endovascular and microsurgical treatment outcomes in patients with unruptured aneurysms. METHODS A prospectively maintained database of consecutive patients with unruptured aneurysm who were treated with clip placement or endovascular therapy was used. Because patient age is an important predictor of treatment outcomes in patients with unruptured aneurysm, mFI-5 was supplemented with age to create the age-supplemented mFI-5 (AmFI-5). Associations of scores on these indices with major complications (symptomatic ischemic or hemorrhagic stroke, pulmonary embolism, pneumonia, or surgical site infection requiring reoperation) were evaluated. Validation was carried out with the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database (2006–2017). RESULTS The institutional database included 275 patients (88 underwent clip placement, and 187 underwent endovascular treatment). Multivariable analysis of the surgical cohort showed that major complication was significantly associated with mFI-5 (OR 2.0, p = 0.046) and AmFI-5 (OR 1.9, p = 0.028) scores. Significant predictive accuracy for major complications was provided by mFI-5 (c-statistic = 0.709, p = 0.011) and AmFI-5 (c-statistic = 0.720, p = 0.008). The American Society of Anesthesiologists Physical Status Classification System (ASA) provided poor discrimination (area under the curve = 0.541, p = 0.618) that was significantly less than that of mFI-5 (p = 0.023) and AmFI-5 (p = 0.014). Optimal relative fit was achieved with AmFI-5, which had the lowest Akaike information criterion value. Similar results were obtained after equivalent analysis of the endovascular cohort, with additional significant associations between index scores and length of stay (β = 0.6 and p = 0.009 for mFI-5; β = 0.5 and p = 0.003 for AmFI-5). In 1047 patients who underwent clip placement and were included in the NSQIP database, mFI-5 (p = 0.001) and AmFI-5 (p < 0.001) scores were significantly associated with severe postoperative adverse events and provided greater discrimination (c-statistic = 0.600 and p < 0.001 for mFI-5; c-statistic = 0.610 and p < 0.001 for AmFI-5) than ASA score (c-statistic = 0.580 and p = 0.003). CONCLUSIONS mFI-5 and AmFI-5 represent potential predictors of procedure-related complications in unruptured aneurysm patients. After further validation, integration of these tools into clinical workflows may optimize patients for intervention.

Background. Elderly and frail patients undergo open emergency colectomies and are at greater risk for complications. The relationship between frailty and open emergent colectomies is yet unexplored.Objective. The purpose of this study was to evaluate the relationship between frailty and outcomes after open emergent colorectal surgery.Design. Using the American College of Surgeons National Quality Improvement Program database, a validated modified frailty index was used, along with logistic regression, to assess the relationship between frailty and outcomes.Main Outcome Measures. Outcomes included mortality (primary), Clavien-Dindo Complication Grade >3, reintubation, ventilator >48 hours, and reoperation (secondary).Results. The rates for 30-day mortality, Clavien-Dindo Grade >3, reintubation, ventilator > 48 hours, and reoperation in our cohort were 16.6%, 36.9%, 8.6%, 23.9%, and 15.0%, respectively. There was a statistically significant increase in prevalence of all outcomes with increasing frailty.Limitations. A causal relationship between frailty and complications cannot be established in a retrospective analysis. Also, extrapolation of our data to reflect outcomes beyond 30 days must be done with caution.Conclusions. Frailty is a statistically significant predictor of mortality and morbidity after open emergent colectomies and can be used in an acute care setting.

Background Frailty has been studied extensively in trauma, but there is minimal research detailing its impact on traumatic brain injury (TBI). We hypothesized that the 11-item modified frailty index (mFI-11) would predict complications and discharge outcomes in patients with TBI. Methods A retrospective review of our trauma quality improvement program (TQIP) registry was conducted for all patients with TBI. The mFI-11 score was calculated for each patient. Multivariable logistic regression was used to assess the relationship between mFI-11 and cardiovascular, infectious, pulmonary, renal, thromboembolic, and unplanned complications (ie, unplanned intensive care unit [ICU] admission, intubation, or return to the operating room). Results There were 2352 patients with TBI of whom 61.6% (n = 1450) were not frail, 19.3% (n = 454) were mildly frail, and 19.1% (n = 448) were moderately to severely frail. Higher frailty scores were associated with increasing age ( P < .0001) and decreasing injury severity score [ISS] ( P = 0.001). Higher frailty scores also correlated with increasing rates of a skilled nursing facility/long-term acute care hospital/rehabilitation discharge ( P = .0002). On multivariable logistic regression adjusting for age, Glasgow Coma Scale (GCS) score, ISS, mechanism, and sex, moderate to severe frailty increased the odds of acute kidney injury (odds ratio [OR] 2.06, 95% CI 1.07-3.99, P = .03) and any unplanned event (OR 1.6, 95% CI 1.1-2.3, P = .01). Conclusion Frailty measured by the mFI-11 is associated with greater rates of discharge to unfavorable locations and increased odds of acute kidney injury and unplanned events among patients with TBI. These findings suggest that frail patients with TBIs require greater vigilance to avoid such unanticipated outcomes.

418 Background: Frailty has been associated with adverse postoperative outcomes. However, little is known about its correlation with survival in resected pancreatic cancer. This study examined the correlation of frailty with postoperative outcomes and survival after pancreatectomy for cancer. Methods: Data from National Surgical Quality Improvement Program (NSQIP) patients (n = 7400) who underwent pancreatectomy between 2011 to 2013. A modified frailty index (mFI) validated for use in NSQIP was used to examine correlations between frailty and postoperative outcomes. California Cancer Registry (CCR) data for patients (n = 4959) who underwent pancreatectomy for cancer between 2000 to 2012 was used to assess the association between the Charlson Comorbidity Index (CCI), as a surrogate for frailty, and overall survival. Results: The distribution of NSQIP patients according to the mFI was 0, 1, 2, 3, 4 in 2797 (37.8%), 3422 (46.2), 1074 (14.5), 104 (1.4) and 3 (0.04) respectively. The patients were divided to non frail (mFI = 0), mildly frail (mFI = 1-2), or severely frail (mFI3 ≥ 3). Overall, 8.7% of patients experienced a grade 4 Clavien complication and 3.1% experienced postoperative mortality. Worsening frailty correlated with an increase in grade 4 Clavien complications (non-frail: 6.3% vs. mildly frail: 9.7% vs. severely frail: 26.2%; p < 0.001) and mortality (1.9% vs. 3.8% vs. 4.7% respectively; p < 0.001). The majority of CCR patients had similarly few comorbidities: CCI: 0, 1, ≥ 2 in 3869 (77.8%), 861 (17.31%) and 243 (4.89%) respectively. Median survival decreased as CCI increased (for CCI 0, 1 and ≥ 2 was 23 vs. 19 vs. 15 months respectively; p < 0.001). Conclusions: Frailty is a powerful correlate of postoperative outcome and survival for resected pancreatic cancer patients and is an important consideration in planning for surgical intervention.

220 Background: Accumulating evidence correlates myocardial injury after noncardiac surgery (MINS), even when asymptomatic, with increased cardiac and non-cardiac morbidity and mortality. There is no literature on MINS specific to Gynecologic Oncology. We sought to evaluate the incidence and risk factors of MINS in patients aged ≥70. Methods: Elective laparotomies between 01/2016-09/2020 for patients aged≥70 at a tertiary hospital in ON, Canada, were reviewed using prospectively-collected National Surgical Quality Improvement Program (NSQIP) data. MINS was defined as peak serum high-sensitivity troponin-T concentration ≥0.04ng/mL within 30 days postoperatively. Logistic regression analysis was performed. Results: In this cohort of 258 patients, of 242 (93.8%) who underwent postoperative troponin screening, 40 (16.5%) experienced MINS without exhibiting ischemic symptoms or ECG changes. The diagnosis of MINS led to a prescription or optimization of cardiovascular medications for 35 patients (87.5%). On univariate analysis, Revised Cardiac Risk Index (RCRI) of 3-5(p = 0.002), history of coronary artery disease (p = 0.003) or insulin-dependent diabetes (p = 0.006), preoperative use of antiplatelets (p = 0.009), beta-blockers (p = 0.02), ACE-inhibitors (ACEI) or angiotensin-receptor blockers (ARB)(p = 0.002) and frailty as defined by the NSQIP modified frailty index-5 (p = 0.02), were associated with greater risk of MINS. Factors reflecting surgical complexity including surgical complexity score, operative duration, blood loss and advanced oncologic stage were not predictive. Multivariable analysis using backward selection procedure identified elevated RCRI and preoperative ACE/ARB as significant risk factors (OR 5.93, 95% CI 1.52-24.31, p = 0.01 and OR 2.4, 95% CI 1.18-5.06, p = 0.02). Conclusions: One in 6 patients in our cohort experienced asymptomatic MINS irrespective of surgical complexity. Our analysis highlights a possible opportunity to optimize cardiac risk factors and to potentially improve perioperative patient safety by reducing morbidity. Routine preoperative cardiac risk-stratification and postoperative cardiac biomarkers monitoring should be considered in elderly patients with gynecologic malignancies.[Table: see text]

Modified Frailty Index

OBJECTIVE Limited tools exist to stratify perioperative risk in patients undergoing spinal procedures. The modified frailty index (mFI) based on the Canadian Study of Health and Aging Frailty Index (CSHA-FI), constructed from standard demographic variables, has been applied to various other surgical populations for risk stratification. The authors hypothesized that it would be predictive of postoperative morbidity and mortality in patients undergoing spine surgery. METHODS The 2006–2010 National Surgical Quality Improvement Program (NSQIP) data set was accessed for patients undergoing spine surgeries based on Current Procedural Terminology (CPT) codes. Sixteen preoperative clinical NSQIP variables were matched to 11 CSHA-FI variables (changes in daily activities, gastrointestinal problems, respiratory problems, clouding or delirium, hypertension, coronary artery and peripheral vascular disease, congestive heart failure, and so on). The outcomes assessed were 30-day occurrences of adverse events. These were then summarized in groups: any infection, wound-related complication, Clavien IV complications (life-threatening, requiring ICU admission), and mortality. RESULTS A total of 18,294 patients were identified. In 8.1% of patients with an mFI of 0 there was at least one morbid complication, compared with 24.3% of patients with an mFI of ≥ 0.27 (p < 0.001). An mFI of 0 was associated with a mortality rate of 0.1%, compared with 2.3% for an mFI of ≥ 0.27 (p < 0.001). Patients with an mFI of 0 had a 1.7% rate of surgical site infections and a 0.8% rate of Clavien IV complications, whereas patients with an mFI of ≥ 0.27 had rates of 4.1% and 7.1% for surgical site infections and Clavien IV complications, respectively (p < 0.001 for both). Multivariate analysis showed that the preoperative mFI and American Society of Anesthesiologists classification of ≥ III had a significantly increased risk of leading to Clavien IV complications and death. CONCLUSIONS A higher mFI was associated with a higher risk of postoperative morbidity and mortality, providing an additional tool to improve perioperative risk stratification.

Abstract IntroductionAneurysmal subarachnoid haemorrhage (aSAH) is a condition with significant morbidity and mortality. In the context of acute brain injury, frailty, sarcopaenia and osteopaenia have become increasing concerns. Multiple indices have been devised in various surgical specialties to predict outcome and guide management. In this study, we examined whether such markers have relevance towards outcomes from acute brain conditions, such as aSAH. MethodsAn observational study in a tertiary neurosurgical unit on 51 consecutive patients with ruptured aSAH was performed. We compared various frailty indices (modified frailty index 11, and 5, and the National Surgical Quality Improvement Program score [NSQIP]), temporalis (TMT) and zygoma thickness (markers of sarcopaenia and osteopaenia), against traditional markers (age, World Federation of Neurological Surgery and modified Fisher scale [MFS]) for aSAH outcomes. ResultsTMT was the best performing marker in our cohort with an AUC of 0.82, Somers’ D statistic of 0.63 and Tau statistic 0.25. Of the frailty scores, the NSQIP performed the best (AUC 0.69, Somer’s D 0.40, Tau 0.16), at levels comparable to traditional markers of aSAH, such as MFS (AUC 0.68, Somer’s D 0.43, Tau 0.17). After multivariate analysis, patients with TMT ≥5.5mm (defined as non-frail), were less likely to experience complications (OR 0.20 [0.06 – 0.069], p = 0.011), and had a larger proportion of favourable mRS on discharge (95.0% vs. 58.1%, p = 0.024) and at 3-months (95.0% vs. 64.5%, p = 0.048). However, the gap between unfavourable and favourable mRS was insignificant at the comparison of 1-year outcomes. ConclusionTMT, as a marker of sarcopaenia, correlated well with the presenting status, and outcomes of aSAH. Frailty, as defined by NSQIP, performed at levels equivalent to aSAH scores of clinical relevance, suggesting that, in patients presenting with acute brain injury, both non-neurological and neurological factors were complementary in the determination of eventual clinical outcomes. Further validation of these markers, in addition to exploration of other relevant frailty indices, may help to better prognosticate aSAH outcomes and allow for a precision medicine approach to decision making and optimization of best outcomes Trial registrationNot applicable

Study Design: Retrospective cohort study. Objective: To assess the impact of race on complications following spinal tumor surgery. Methods: Adults with cancer who underwent spine tumor surgery were identified in the American College of Surgeons National Surgical Quality Improvement Program datasets from 2012 to 2016. Clavien-Dindo Grade I-II (minor complications) and Clavien-Dindo Grade III-V (major complications including 30-day mortality) complications were compared between non-Hispanic Whites (NHW) and Black patients. A multivariable analysis was also conducted. Results: Of 1,226 identified patients, 85.9% were NHW (n = 1,053) and 14.1% were Black (n = 173). The overall rate of Grade I-II complications was 16.2%; 15.1% for NHW patients and 23.1% for Black patients ( P = .008). On multivariable analysis, Black patients had significantly higher odds of having a minor complication (OR 1.87; 95% CI, 1.16-3.01; P = .010). On the other hand, the overall rate of Grade III-V complications was 13.3%; 12.5% for NHW patients and 16.2% for Black patients ( P = .187). On multivariable analysis, Black race was not independently associated with major complications (OR 1.26; 95% CI, 0.71-2.23; P = .430). Median length of stay was 8 days (IQR 5-13) for NHW patients and 10 days (IQR 6-15) for Black patients ( P = .011). Conclusion: Black patients who underwent metastatic spinal tumor surgery were at a significantly increased risk of perioperative morbidity compared to NHW patients independent of baseline and operative characteristics. Major complications did not differ between groups. Race should be further studied in the context of metastatic spine disease to improve our understanding of these disparities.
