IMPORTANCE Patients with frailty have higher risk for postoperative mortality and complications; however, most research has focused on small groups of high-risk procedures. The associations among frailty, operative stress, and mortality are poorly understood.OBJECTIVE To assess the association between frailty and mortality at varying levels of operative stress as measured by the Operative Stress Score, a novel measure created for this study. DESIGN, SETTING, AND PARTICIPANTSThis retrospective cohort study included veterans in the Veterans Administration Surgical Quality Improvement Program from April 1, 2010, through March 31, 2014, who underwent a noncardiac surgical procedure at Veterans Health Administration Hospitals and had information available on vital status (whether the patient was alive or deceased) at 1 year postoperatively. A Delphi consensus method was used to stratify surgical procedures into 5 categories of physiologic stress. EXPOSURES Frailty as measured by the Risk Analysis Index and operative stress as measured by the Operative Stress Score. MAIN OUTCOMES AND MEASURES Postoperative mortality at 30, 90, and 180 days. RESULTS Of 432 828 unique patients (401 453 males [92.8%]; mean (SD) age, 61.0 [12.9] years), 36 579 (8.5%) were frail and 9113 (2.1%) were very frail. The 30-day mortality rate among patients who were frail and underwent the lowest-stress surgical procedures (eg, cystoscopy) was 1.55% (95% CI, 1.20%-1.97%) and among patients with frailty who underwent the moderate-stress surgical procedures (eg, laparoscopic cholecystectomy) was 5.13% (95% CI, 4.79%-5.48%); these rates exceeded the 1% mortality rate often used to define high-risk surgery. Among patients who were very frail, 30-day mortality rates were higher after the lowest-stress surgical procedures (10.34%; 95% CI, 7.73%-13.48%) and after the moderate-stress surgical procedures (18.74%; 95% CI, 17.72%-19.80%). For patients who were frail and very frail, mortality continued to increase at 90 and 180 days, reaching 43.00% (95% CI, 41.69%-44.32%) for very frail patients at 180 days after moderate-stress surgical procedures. CONCLUSIONS AND RELEVANCEWe developed a novel operative stress score to quantify physiologic stress for surgical procedures. Patients who were frail and very frail had high rates of postoperative mortality across all levels of the Operative Stress Score. These findings suggest that frailty screening should be applied universally because low-and moderate-stress procedures may be high risk among patients who are frail.

IMPORTANCEFrailty is an important risk factor for postoperative mortality. Whether the association between frailty and mortality is consistent across all surgical specialties, especially those predominantly performing lower stress procedures, remains unknown.OBJECTIVE To examine the association between frailty and postoperative mortality across surgical specialties. DESIGN, SETTING, AND PARTICIPANTSA cohort study was conducted across 9 noncardiac specialties in hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) and Veterans Affairs Surgical Quality Improvement Program (VASQIP) from January 1, 2010, through December 31, 2014, using multivariable logistic regression to evaluate the association between frailty and postoperative mortality. Data analysis was conducted from September 15, 2019, to April 30, 2020. Patients 18 years or older undergoing noncardiac procedures were included.EXPOSURES Risk Analysis Index measuring preoperative frailty categorized patients as robust (Risk Analysis Index Յ20), normal (21-29), frail (30-39), or very frail (Ն40). Operative Stress Score (OSS) categorized procedures as low (1-2), moderate (3), and high (4-5) stress. Specialties were categorized by case-mix as predominantly low intensity (>75% OSS 1-2), moderate intensity (50%-75%), or high intensity (<50%).MAIN OUTCOMES AND MEASURES Thirty-day (both measures) and 180-day (VASQIP only) postoperative mortality. RESULTSOf the patients evaluated in NSQIP (n = 2 339 031), 1 309 795 were women (56.0%) and mean (SD) age was 56.49 (16.4) years. Of the patients evaluated in VASQIP (n = 426 578), 395 761 (92.78%) were men and mean (SD) age was 61.1 (12.9) years. Overall, 30-day mortality was 1.2% in NSQIP and 1.0% in VASQIP, and 180-day mortality in VASQIP was 3.4%. Frailty and OSS distributions differed substantially across the 9 specialties. Patterns of 30-day mortality for frail and very frail patients were similar in NSQIP and VASQIP for low-, moderate-, and high-intensity specialties. Frailty was a consistent, independent risk factor for 30-and 180-day mortality across all specialties. For example, in NSQIP, for plastic surgery, a low-intensity specialty, the odds of 30-day mortality in very frail (adjusted odds ratio [aOR], 27.99; 95% CI,) and frail (aOR, 5.1; 95% CI, 3.03-8.58) patients were statistically significantly higher than for normal patients. This was also true in neurosurgery, a moderate-intensity specialty, for very frail (aOR, 9.8; 95% CI, 7.68-12.50) and frail (aOR, 4.18; 95% CI, 3.58-4.89) patients and in vascular surgery, a high-intensity specialty, for very frail (aOR, 10.85; 95% CI, 9.83-11.96) and frail (aOR, 3.42; 95% CI, 3.19-3.67) patients. CONCLUSIONS AND RELEVANCEIn this study, frailty was associated with postoperative mortality across all noncardiac surgical specialties regardless of case-mix. Preoperative frailty assessment could be implemented across all specialties to facilitate risk stratification and shared decision-making.

Although current ATA recommendations for the management of GD call for routine use of KI before thyroidectomy, this large series demonstrates no appreciable detriment to patient outcomes when this goal is not met.

Background Total thyroidectomy (TT) is the preferred surgical approach to Graves' disease (GD). Current American Thyroid Association (ATA) guidelines call for administration of potassium iodide (KI) and achievement of euthyroid state before operation. Small numbers and a mixture of surgical approaches spanning several decades hinder previous surgical series. We present the outcomes for TT at a single high-volume center. Methods A retrospective cohort study was conducted on 165 patients undergoing TT for GD from 7/2007 to 5/2012. Results Mean age was 43 years (Range: 17-78), and 128 patients (78%) were female. 95% of patients were on methimazole or propylthiouracil, and 42% remained hyperthyroid at time of surgery. Only 3 (2%) patients received KI. Mean operative time was 132 minutes (Range 59-271). Mean gland size and blood loss were 41 grams (Range 8-180) and 55 mL (Range 10-1050), respectively. No patient developed thyroid storm. Median follow-up was 7.5 months. Temporary and permanent hypocalcemia developed in 51 (31%) and two patients (1.2%), respectively. Temporary and permanent recurrent laryngeal nerve paresis occurred in 12 (7%) and one (0.6%) patient, respectively. Sixty-one (37%) patients experienced at least one complication. On multivariate analysis, patient age less than 45 years (OR 2.93, 95% CI 1.39-6.19) and obesity (OR 2.11, 95% CI 1.00-4.43) were associated with occurrence of complications. Conclusion This high-volume surgeon experience demonstrates no appreciable detriment to patient outcomes when ATA recommendations for routine use of KI and euthyroid state before thyroidectomy are not met. Transient hypocalcemia and hoarseness are frequent complications of TT for GD resolving within six months in most patients. Age less than 45 years and obesity are risk factors for post-operative complications.

BACKGROUNDFrailty is a marker of dependency, disability, hospitalization, and mortality in community‐dwelling older adults. However, existing tools for measuring frailty are too cumbersome for rapid point‐of‐care assessment. The Risk Analysis Index (RAI) of frailty is validated in surgical populations, but its performance outside surgical populations is unknown.OBJECTIVEValidate the RAI in ambulatory patients.DESIGN, SETTING, AND PARTICIPANTSObservational cohort study of outpatient surgical clinics within the University of Pittsburgh Medical Center Healthcare System between July 1, 2016, and December 31, 2016. Frailty was assessed using the RAI. Current Procedural Terminology codes following RAI assessment identified patients with and without minor office‐based procedures (eg, joint injection, laryngoscopy).MAIN OUTCOMES AND MEASURESAll‐cause 1‐year mortality, assessed by stratified Cox proportional hazard models.RESULTSOf 28,059 patients, 13,861 were matched to a minor, office‐based procedure and 14,198 did not undergo any procedure. The mean (SD) age was 56.7 (17.2) years; women constituted 15,797 (56.3%) of the cohort. Median time (interquartile range 25th‐75th percentile) to measure RAI was 30 (22–47) seconds. Mortality among the frail was two to five times that of patients with normal RAI scores. For example, the hazard ratio for frail ambulatory patients without a minor procedure was 3.69 (95% confidence interval [CI] = 2.51‐5.41), corresponding to 30‐, 180‐, and 365‐day mortality rates of 2.9%, 11.2%, and 17.4%, respectively, compared to 0.3%, 2.3%, and 4.0% among patients with normal RAI scores. Discrimination of mortality (overall, and censored at 30, 180, and 365 days) was excellent, ranging from c = 0.838 (95% CI = 0.773‐0.902) for 30‐day mortality after minor procedures to c = 0.909 (95% CI = 0.855‐0.964) without a procedure.CONCLUSIONRAI is a valid, easily administered tool for point‐of‐care frailty assessment in ambulatory populations that may help clinicians and patients make better informed decisions about care choices—especially among patients considered high risk with a potentially limited life span.

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.
