Study Design: Retrospective cohort. Objectives: To validate the 11-item modified Frailty Index (mFI) as a perioperative risk stratification tool in elderly patients undergoing spine surgery. Methods: All consecutive cases of spine surgery in patients aged 65 years or older between July 2016 and June 2018 at a state-wide trauma center were retrospectively reviewed. The primary outcome was post-operative major complication rate (Clavien-Dindo Classification ≥ III). Secondary outcome measures included the rate of all complications, 6-month mortality and surgical site infection. Results: A total of 348 cases were identified. The major complication rate was significantly lower in patients with an mFI of 0 compared to ≥ 0.45 (18.3% versus 42.5%, P = .049). As the mFI increased from 0 to ≥ 0.45 there was a stepwise increase in risk of major complications ( P < .001). Additionally, 6-month mortality rate was considerably lower when the mFI was 0 rather than ≥ 0.27 (4.2% versus 20.4%, P = .007). Multivariate analysis demonstrated an mFI ≥ 0.27 was significantly associated with an increased incidence of major complication (OR 2.80, 95% CI 1.46-5.35, P = .002), all complication (OR 2.93, 95% CI 1.70-15.11, P < .001), 6-month mortality (OR 7.39, 95% CI 2.55-21.43, P < .001) and surgical site infection (OR 4.43, 95% CI 1.71-11.51, P = .002). The American Society of Anesthesiologists’ (ASA) index did not share a stepwise relationship with any outcome. Conclusion: The mFI is significantly associated in a gradated fashion with increased morbidity and mortality. Patients with an mFI ≥ 0.27 are at greater risk of major complications, all-complications, 6-monthy mortality, and surgical site infection.

Modified Frailty Index

Study Design: This was an ambispective clinical quality registry study. Objective: To evaluate utility of 11-variable modified Frailty Index (mFI) in predicting postoperative outcomes among patients ≥80 years undergoing spinal surgery. Methods: Consecutive patients ≥80 years who underwent spinal surgery between January 1, 2013, and June 30, 2018, were included. Primary outcome measure was rate of major complication. Secondary outcome measures were (1) overall complication rate, (2) surgical site infection, and (3) 6-month mortality. Results: A total of 121 operations were performed. Demographic metrics were (1) age (mean ± SD) = 83.1 ± 2.8 years and (2) mFI (mean ± SD) = 2.1 ± 1.4 variables. As mFI increased from 0 to ≥4 variables, risk of major complication increased from 18.2% to 40.0% ( P = .014); overall complication increased from 45.5% to 70.0% ( P = .032); surgical site infection increased from 0.0% to 25.0% ( P = .007). There were no significant changes in risk of 6-month mortality across mFIs ( P = .115). Multivariate analysis showed that a higher mFI score of ≥3 variables was associated with a significantly higher risk of (1) major complication ( P = .025); (2) overall complication ( P = .015); (3) surgical site infection ( P = .007); and (4) mortality ( P = .044). Conclusions: mFI scores of ≥3/11 variables were associated with a higher risk of postoperative morbidity in patients aged ≥80 years undergoing spinal surgery. The mFI-associated risk stratification provides a valuable adjunct in surgical decision making for this rapidly growing subpopulation of patients.

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.

Objective The aim was to evaluate the utility of frailty, as defined by the modified Frailty Index-1 1 (mFI-11) on predicting outcomes following endovascular revascularisation in Asian patients with chronic limb-threatening ischaemia (CLTI). Methods CLTI patients who underwent endovascular revascularisation between January 2015 and March 2017 were included. Patients were retrospectively scored using the mFI-11 to categorise frailty as low, medium or high risk. Observed outcomes included 30-day complication rate and unplanned readmissions, 1-, 6- and 12-month mortality, and ambulation status at 6- and 12 months post-intervention. Results A total of 233 patients (250 procedures) were included; 137 (58.8%) were males and the mean age was 69.0 (±10.7) years. 202/233 (86.7%) were diabetic and 196/233 (84.1%) had a prior diagnosis of peripheral arterial disease (PAD). The mean mFI-11 score was 4.2 (±1.5). 28/233 (12.0%), 155/233 (66.5%), and 50/233 (21.5%) patients were deemed low (mF-11 score 0–2), moderate (mFI-11 score 3–5) and high (mFI-11 score 5–7) frailty risk, respectively. High frailty was associated with an increased 12-month mortality (OR 8.54, 95% CI 1.05–69.5; p = 0.05), 30-day complication rate (OR 9.41, 95% CI 2.01–44.1; p < 0.01) and 30-day unplanned readmission (OR 5.06, 95% CI 1.06–24.2; p = 0.04). Furthermore, a high score was associated with a significantly worse 6- (OR 0.320, 95% CI 0.120–0.840; p = 0.02) and 12-month (OR 0.270, 95% CI 0.100–0.710; p < 0.01) ambulatory status. Conclusion The mFI-11 is a useful, non-invasive tool that can be readily calculated using readily available patient data, for prediction of medium-term outcomes for Asian CLTI patients following endovascular revascularisation. Early recognition of short- and mid-term loss of ambulation status amongst high-frailty patients in this challenging cohort of patients could aid decision-making for whether a revascularisation or amputation-first policy is appropriate, and manage patient and caregiver expectations on potential improvement in functional outcome.

Abstract INTRODUCTION ISAT demonstrated that coiling is effective for aneurysm treatment in subarachnoid hemorrhage (SAH); however, complete occlusion of wide-necked aneurysms frequently requires adjuvants relatively contraindicated in SAH. As such, a limited “dome occlusive” strategy is often pursued in the setting of SAH. We report a single institution series of coiling of acutely ruptured aneurysms followed by delayed flow diversion for definitive, curative occlusion. METHODS A prospectively collected IRB-approved database was screened for patients with aneurysmal SAH who were initially treated by coil embolization followed by planned flow diversion at a single academic medical institution. Peri-procedural outcomes, complications, and angiographic follow-up were analyzed. RESULTS >50 patients underwent both acute coiling followed by delayed, planned flow diversion. Average aneurysm size on initial presentation was 9.5 mm. Common aneurysm locations included Pcomm (36%), Acomm (30%), MCA (10%), ACA (10%), and vertebral (5%). Dome occlusion was achieved in all cases following initial coiling. Second-stage implantation of a flow diverting stent was achieved in 49/50 cases (98%). Follow-up angiography was available for 33/50 patients (66%), with mean follow-up of 11 months. 27 patients (82%) had complete angiographic occlusion at last follow up. All patients with residual filling at follow-up still had dome occlusion. There were no mortalities (0%). Major complication rate for stage I coiling was 2% (1 patient with intra-procedural aneurysm re-rupture causing increase in a previous ICH). Major complication rate for stage 2 flow diversion was 2% (1 patient with ischemic stroke following noncompliance with dual antiplatelet regimen). Minor complications occurred in 2 additional patients (4%) with transient neurological deficits. CONCLUSION Staged endovascular treatment of ruptured intracranial aneurysms with acute dome-occlusive coil embolization followed by delayed flow diversion is a safe and effective treatment strategy.
