Abstract Background There is conflicting evidence in the literature regarding whether type of anesthesia (regional vs. general) is associated with postoperative mortality in patients undergoing hip arthroplasty. The present study compares mortality between general or regional anesthesia administered to patients undergoing either total (THA) or partial hip arthroplasty (PHA). Methods A retrospective cohort was assembled using the 2015-2016 American College of Surgeons National Surgical Quality Improvement Program database. Adult patients undergoing hip arthroplasty under general or regional anesthesia were included. Adjusted odds of 30 days all-cause postoperative mortality according to type of anesthesia were estimated by fitting multiple logistic regression models that included potential confounders and effect modifiers. Results A total of 60,897 patients were included. Given that the interaction between type of anesthesia and type of arthroplasty was statistically significant, separated models were fitted for each type of arthroplasty. There was no evidence of an association between type of anesthesia and postoperative mortality in hip arthroplasty patients regardless of whether the arthroplasty was partial (OR = 0.85; CI 0.59-1.22) or total (OR = 0.68; CI 0.43-1.08). Conclusion The overall postoperative mortality in adult hip arthroplasty patients is low. Our findings support that mortality is not different between patients receiving regional vs general anesthesia regardless of type of hip arthroplasty (total vs. partial). Key Message In patients undergoing total hip arthroplasty or partial hip arthroplasty, the use of general or regional anesthesia does not impact early postoperative mortality.

Estimating surgeon-level value in health care remains relatively unexplored. American College of Surgeons National Surgical Quality Improvement Program Participant Use Files (2005-2013) were linked with total costs at a single institution. Random intercepts in 3-level random effects logistic regression models predicted 30-day postoperative mortality or morbidity for each surgeon each year. Value was defined as quality (morbidity or mortality) divided by costs for surgeons performing general surgery and vascular procedures. Forty-four surgeons performed 11 965 surgeries. Risk-adjusted costs trended down over time. For all surgeries, mortality value increased by 3.27 per year (95% confidence interval = 2.54-4.01; P < .001) on a 100-point scale, while morbidity value did not change. Of 21 surgeons with data for 5 years or longer, mortality value increased for all surgeons except one. Continuous increase in complication rates from 2008 contributed to decreased morbidity value. Value may assist surgeons in exploring performance opportunities better than morbidity or mortality alone.

Aims The aim of this study was to assess the influence of operating time on 30-day complications following total hip arthroplasty (THA). Patients and Methods We identified patients aged 18 years and older who underwent THA between 2006 and 2016 from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. We identified 131 361 patients, with a mean age of 65 years (sd 12), who underwent THA. We used multivariable regression to determine if the rate of complications and re-admissions was related to the operating time, while adjusting for relevant covariables. Results The mean operating time decreased from 118.3 minutes (29.0 to 217.0) in 2006, to 89.6 minutes (20.0 to 240.0) in 2016. After adjustment for covariables, operating times of between 90 and 119 minutes increased the risk of minor complications by 1.2 (95% confidence interval (CI) 1.1 to 1.3), while operating times of between 120 and 179 minutes increased the risk of major complications by 1.4 (95% CI 1.3 to 1.6) and minor complications by 1.4 (95% CI 1.2 to 1.5), and operating times of 180 minutes or more increased the risk of major complications by 2.1 (95% CI 1.8 to 2.6) and minor complications by 1.9 (95% CI 1.6 to 2.3). There was no difference in the overall risk of complications for operating times of between 20 and 39, 40 and 59, or 60 and 89 minutes (p > 0.05). Operating times of between 40 and 59 minutes decreased the risk of re-admission by 0.88 (95% CI 0.79 to 0.97), while operating times of between 120 and 179 minutes, and of 180 minutes or more, increased the risk of re-admission by 1.2 (95% CI 1.1 to 1.3) and 1.6 (95% CI 1.3 to 1.8), respectively. Conclusion These findings suggest that an operating time of more than 90 minutes may be an independent predictor of major and minor complications, as well as re-admission, following THA, and that an operating time of between 40 and 90 minutes may be ideal. Prospective studies are required to confirm these findings. Cite this article: Bone Joint J 2019;101-B(6 Supple B):51–56.

Abstract Background Various surgical risk assessment tools, including the American College of Surgeons National Surgical Quality Improvement Program® (ACS NSQIP®) risk calculator have been devised to predict post-operative mortality. However, the role of individual factors on mortality is unclear. We sought to identify patient characteristics from the database that were associated with postoperative mortality in patients undergoing elective, non-cardiac surgery.Methods Data from the ACS NSQIP® database at a tertiary care academic medical center was analyzed from January 2011 to September 2016. Relevant patient related variables were extracted from the database and univariable logistic regression was used to assess the association of each potential risk factor with 30-day mortality. A multivariable logistic regression model was then used to assess the adjusted effect of each potential risk factor on the outcome.Results 5,254 database patient records were identified and among the analyzed variables, American Society of Anesthesiologists (ASA) physical status III and IV (odds ratio and 95%CI : 16.75 [2.29, 122.69] ), poor preoperative functional health status (Odds ratio and 95%CI : 38.52 [2.46, 604.12] ), and low serum albumin (Odds ratio and 95%CI : 3.76 [1.35, 10.44]) were significant predictors of 30-day postoperative mortality.Conclusions In a comprehensive analysis of the ACS NSQIP®database, spreading across multiple surgical specialties, we found an association between ASA physical status, preoperative albumin levels, and functional health status with 30-day mortality after elective non-cardiac surgery.

153 Background: Several single-center reports have been published suggesting that vascular reconstruction (VR) during pancreaticoduodenectomy (PD) allows an acceptable oncologic outcome in patients with pancreatic adenocarcinoma without affecting early postoperative mortality or morbidity. The objective of our study was to review the outcomes associated with VR during PD using a large multicenter data source. Methods: A retrospective cohort analysis was performed using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) Participant User Files for 2005-2009. All patients undergoing PD for a postoperative diagnosis of malignant neoplasm of the pancreas were included. Forward stepwise multivariate regression analysis was used to determine the association between VR during PD and 30-day postoperative mortality and morbidity after adjusting for patient demographics and comorbidities. Results: 3582 patients were included for analysis, 281 (7.8%) of whom underwent VR during PD. VR during PD was associated with significantly greater risk-adjusted 30-day postoperative mortality (5.7% with VR vs. 2.9% without VR, Adjusted Odds Ratio (AOR) 2.1, 95% CI 1.22-3.73, p = 0.008) and overall morbidity (39.9% with VR vs. 33.3% without VR, AOR 1.36, 95% CI 1.05-1.75, p = 0.02). Patients undergoing VR required significantly longer operative times, and were more likely to require intraoperative transfusion or early reoperation, than patients not undergoing VR during PD. There was no significant difference in risk-adjusted postoperative mortality or morbidity between those patients undergoing VR by the primary surgical team versus those patients undergoing VR by a vascular surgical team. Conclusions: Contrary to the findings of several previously published single-center analyses, data from ACS-NSQIP suggests that VR significantly increases the risk of 30-day postoperative death or complications after PD. Patients who may require VR during PD will likely benefit from referral to centers with sufficient experience with this procedure.

Purpose: Emergency hip surgery generally has worse outcomes than elective hip surgery, even when adjusted for patient and surgical factors. Do-not-resuscitate (DNR) status patients are typically at higher perioperative risk and undergo a narrow range of surgical procedures. We aimed to compare the outcomes after hip surgery of differing degrees of urgency in this cohort. Materials and Methods: Using National Surgical Quality Improvement Program (NSQIP) data, we conducted univariate and multivariate analyses comparing outcomes of DNR status patients after emergency and nonemergency hip surgery (2007-2013). We conducted a subanalysis of mortality in elective versus nonelective cases (elective variable introduced from 2011). Results: Of 668 hip surgery cases in DNR status patients, 210 (31.4%) were emergency and 458 (68.8%) were nonemergency. There were no significant associations between emergency and nonemergency surgery regarding patient demographics, comorbidities, functional capacity, anesthesia type, or operative duration. There was no significant difference in the 30-day postoperative mortality between emergency (21.4%) and nonemergency (16.4%) or between elective (19.6%) and nonelective (18.3%) hip fracture surgeries performed in patients with preexisting DNR status. Morbidity patterns in emergency vs nonemergency cases demonstrated no significant differences, with the commonest 3 complications being transfusion (21.0% and 21.4%, respectively), urinary tract infection (9.5% and 7.9%, respectively), and pneumonia (both at 5.2%). The 30-day home discharge rates were low at 4.7% and 5.6%, respectively. Multivariate analysis demonstrated no significant associations between emergency and nonemergency surgery for mortality, discharge destination, length of stay or complications, except perioperative myocardial infarction (3.7% vs 1.3%, P < .04). Conclusion: For patients with DNR status, both emergent and non-emergent hip surgery carries high mortality, greatly exceeding rates predicted for that patient by American College of Surgeons NSQIP risk calculators. Morbidity rates and patterns for patients with DNR status are also similar in emergency and nonemergency groups. These data may be useful in discussing risk and obtaining adequately informed consent in DNR patients undergoing hip surgery.
