The impact of enteric fistulas on US hospital systems.

BACKGROUND: There is limited characterization of patients with enteric fistula. Our objective is to determine the incidence of the disease, and characterize demographics, healthcare costs, co-diagnoses, and procedures in this population. METHODS: The National Inpatient Sample database 2004-2014 was queried to identify patients with enteric fistula using ICD-9 code 569.81. RESULTS: There were 317,000 admissions with a diagnosis of enteric fistula from 2004 to 2014, accounting for 230,000 hospital days annually. Costs totaled $500 million with charges of $1.5 billion annually. Inpatient mortality is 4.1%. Patients had significant comorbidities and 3 procedures or surgical interventions per admission. CONCLUSIONS: This descriptive study elucidates the impact of enteric fistula on patients and hospitals by characterizing incidence, clinical associations, and admission characteristics. There is significant financial impact with 28,000 admissions and $500 million dollars in annual costs. This study lays the groundwork for future research by characterizing the impact of enteric fistula.

Risk of adding prophylactic aorta replacement to a cardiac operation.

OBJECTIVE: The study objective was to determine whether adding prophylactic aorta replacement increases the risk of a cardiac operation when cardiac rather than aortic disease is the primary indication for operation. METHODS: Patients undergoing cardiac operations with aorta replacement (cardioaortic group), with or without circulatory arrest, were propensity matched to identify patients whose combined operation was not primarily indicated by aortic disease (n = 684). These patients were further propensity matched without accounting for thoracic-aortic measurements to patients undergoing cardiac operations without aorta replacement (cardiac-surgery only group), 647 pairs, for comparing outcomes. RESULTS: Most (n = 431/503 [86%]) propensity-matched patients undergoing cardioaortic operations had ascending aorta dilatation with a maximum aortic diameter of less than 5.5 cm. There was no evidence of an incremental increase in risk of in-hospital stroke (cardioaortic, n = 9/1.4% vs cardiac only, n = 7/1.1%; P = .6) or mortality (cardioaortic, n = 6/0.93% vs cardiac only, n = 3/0.46%; P = .5). Unmatched patients undergoing concomitant aortic surgery had advanced aortic disease distal to the ascending aorta (arch, 3.8 ± 0.98 cm vs 3.2 ± 0.51 cm; descending, 4.4 ± 1.7 cm vs 3.2 ± 0.99 cm) as the primary indication for their operation and had a high occurrence of in-hospital stroke (6.5% vs 1.5%, P = .0007) and death (7% vs 1.2%, P = .0001). CONCLUSIONS: Prophylactic aorta replacement can be safely performed during a cardioaortic operation, without added penalty, when aortic disease is less severe and not the primary indication for surgery. Risks after an aorta replacement combined with cardiac surgery can be substantial, however, when advanced aortic disease is the primary indication for operation. These distinctive risks should be taken into consideration at the time of surgical decision-making.

Outcomes of Repair of Kommerell Diverticulum.

BACKGROUND: Kommerell diverticulum (KD) is an uncommon congenital vascular anomaly. This study assessed outcomes of open and endovascular repair of this disorder. METHODS: Between 1997 and 2016, 152 adult patients presented with KD at Cleveland Clinic (Cleveland, OH), 87 had no intervention, and 65 underwent open repair (n = 55; 19 elephant trunk [ET] procedures [9 with aortic dissection], including 7 frozen ET, and completions with 5 thoracic endovascular aortic repairs, 2 open, and 5 lost to follow-up) or endovascular procedures (n = 10). Non-ET open KD repairs consisted of resection (n = 15), interposition graft (n = 16), patch (n = 4), or aortopexy (n = 1). Maximum KD diameter was 2.1 cm for nonsurgical patients and 3.2 cm for surgical patients. Among surgical patients, 51 of 65 had dysphagia or dyspnea. A total of 608 patient-years of follow-up were available. RESULTS: For patients who underwent open and endovascular procedures, after multivariable adjustment, symptoms of dysphagia and hypertension predicted the likelihood of surgery (P < .05, all). There was no operative mortality. Complications included nondisabling stroke (n = 5; 8%), tracheostomy (n = 3; 4.6%), vocal cord paralysis (n = 2; 3%), and reoperation for bleeding (n = 3; 4.6%). During follow-up, 3 of 10 patients treated with hybrid or endovascular procedures required reinterventions for endoleaks. One patient had residual symptoms after aortopexy. Among nonsurgical patients, 2 patients refused surgery, and 1 died of aortic rupture, with a 4.7-cm descending aorta and a 3.4-cm KD. Seven additional patients died of nonaortic comorbidities. The remaining patients were asymptomatic, with an aortic diameter smaller than 4.5 cm. CONCLUSIONS: Open and endovascular approaches have a high success rate and low mortality risk. Selection of the specific type of intervention should be based on patient anatomy, additional needed procedures, and comorbid conditions.

Evaluating the Accuracy of Hemorrhoids: Comparison Among Specialties and Symptoms.

BACKGROUND: A large proportion of patients with anorectal complaints are referred to colorectal surgeons with the label of hemorrhoids. OBJECTIVE: The purpose of this study was to review presenting symptoms and frequency of accurate diagnosis, as well as to analyze determinants of misdiagnosis to guide educational endeavors. DESIGN: This was a retrospective study. SETTINGS: The study was conducted at a tertiary care academic center. PATIENTS: The charts of patients referred to a colorectal clinic with the diagnosis of hemorrhoids from January 1, 2012, to January 1, 2017, were reviewed. MAIN OUTCOME MEASURES: The accuracy of the referring provider's diagnosis of hemorrhoids was measured. RESULTS: Review of charts identified 476 patients with the referral diagnosis of hemorrhoids. The most common presenting symptoms were bleeding (63%; n = 302), pain (48%; n = 228), and protrusion (39%; n = 185). Anal examination (ie, external inspection and/or digital internal examination) was documented in only 48%. The hemorrhoid diagnostic accuracy was 65% (n = 311). Among patients with incorrect hemorrhoid diagnoses (35%; n = 169), actual diagnosis was anal fissure (34%), skin tag (27%), and hypertrophied papilla (6%). One rectal and 2 anal carcinomas were found (0.63%). Compared with general practitioners, gastroenterologists had 86% higher odds of correct diagnosis (OR = 1.86 (95% CI, 1.10-3.10); p = 0.02), whereas the gynecologists had 68% lower odds of correct diagnosis at the time of referral (OR = 0.32 (95% CI, 0.10-0.80); p = 0.02). On multivariable analysis, referring specialty was not predictive of accurate diagnosis. Patients presenting with protrusion had 73% higher odds of accurate diagnosis (OR = 1.7 (95% CI, 1.1-2.7); p = 0.02), whereas patients presenting with pain (OR = 1.6 (95% CI, 1.1-2.5); p = 0.03) or pruritus (OR = 2.5 (95% CI, 1.2-5.0); p = 0.008) were more likely to be misdiagnosed. LIMITATIONS: This is a retrospective study. Not all of the charts contained all data points. The number of patients may limit the power of the study to detect some differences. CONCLUSIONS: A variety of anorectal complaints are diagnosed as hemorrhoids by providers who have initial contact with the patients. Educational programs directed toward improving physician knowledge can potentially improve diagnostic accuracy and earlier initiation of appropriate care. Presenting symptoms other than protrusion lead to higher rate of misdiagnosis by a referring physician. See Video Abstract at http://links.lww.com/DCR/A847.

Total abdominal colectomy is cost-effective in treating colorectal cancer in patients with genetically diagnosed Lynch Syndrome.

BACKGROUND: Lynch syndrome (LS) has a 80% lifetime risk of developing colorectal cancer and metachronous cancer. No studies have examined the quality adjusted life expectancy after SEG or TAC for LS patients, which this study was aiming for. If TAC offers a higher quality adjusted life year (QALY) to SEG in LS patients, preoperative diagnosis of LS is critical as it alters the recommended surgical procedure. METHODS: A Markov decision tree was constructed using Treeage software to compare QALY of LS patients following SEG or TAC. Probabilities, cost, and utility were obtained from literature. Cost-effectiveness analyses were performed. RESULTS: TAC dominates SEG as both the life-saving and cost-saving strategy. TAC dominated SEG on QALY (17.80 vs 17.13 QALY) for a cohort of LS patients diagnosed at an average of 30 year old and followed every 2 years after initial surgery. CONCLUSIONS: We conclude that TAC as the primary surgical option for LS patients diagnosed with Stage I-III colon cancer is cost-effective. Further cost-effectiveness study is recommended to include extra-colonic malignancies in LS patients.

Cannulation strategies in acute type A dissection repair: A systematic axillary artery approach.

OBJECTIVES: Consensus regarding initial cannulation site for acute type A dissection repair is lacking. Objectives were to review our experience with systematic initial axillary artery cannulation, characterize patients on the basis of cannulation site, and assess outcomes. METHODS: From January 2000 to January 2017, 775 patients underwent emergency acute type A dissection repair. Initial axillary cannulation was performed in 617 (80%), femoral in 93 (12%), and central in 65 (8.4%). In-hospital mortality and stroke risk factors were identified using logistic regression. RESULTS: Reasons for selecting initial central or femoral instead of axillary cannulation included unsuitable axillary anatomy (n = 67; 42%), surgeon preference (n = 38; 24%), hemodynamic instability (n = 34; 22%), and preexisting cannulation (n = 19; 12%). Cannulation site was shifted or added intraoperatively in 82 (11%), with initial cannulation site being axillary (n = 23 of 617; 3.7%), central (6 of 65; 9.2%), or femoral (n = 53 of 93; 57%), for surgeon preference (n = 60; 73%), high flow resistance (n = 13; 16%), increased aortic false lumen flow (n = 6; 7.3%), and other (n = 3; 3.7%). In-hospital mortality was 8.6% (n = 67; lowest for axillary, 7.3% [P = .02]) and stroke 8.3% (n = 64). Hemodynamic instability (odds ratio [OR], 7.6; 95% confidence interval [CI], 4.2-14), limb ischemia (OR, 3.7; 95% CI, 1.5-9.3), stroke (OR, 5.5; 95% CI, 2.2-14), and aortic regurgitation (OR, 2.2; 95% CI, 1.2-4.2) at presentation were risk factors for mortality and central cannulation site (OR, 2.3; 95% CI, 1.05-5.1) and aortic stenosis (OR, 2.4; 95% CI, 1.2-4.6) for stroke. CONCLUSIONS: Systematic initial axillary cannulation for acute type A dissection repair is safe and effective and can be tailored to patients' specific needs. With this strategy, comparable outcomes are observed among cannulation sites and are largely determined according to patient presentation rather than cannulation site.

Outcomes Among 196 Patients With Noninfectious Proximal Aortitis.

OBJECTIVE: Noninfectious aortitis may occur in the context of a recognized systemic disease or as a topographically limited lesion without systemic features, which is called clinically isolated aortitis (CIA). This study was undertaken to better define and stress the limitations of this diagnostic category in a large population of patients in a single center dedicated to aortic diseases and to suggest recommendations for care. METHODS: Records of patients undergoing thoracic aortic surgery (1996-2012) at the Cleveland Clinic were reviewed to identify 196 patients with histopathologically proven aortitis. Clinical diagnoses (giant cell arteritis [GCA], Takayasu arteritis [TAK], CIA, or Other) were determined at the time of surgery. Clinical features, laboratory findings, and imaging results were recorded throughout the follow-up period. At least 6 months of follow-up data were available for 73 CIA patients. RESULTS: The mean age of the patients at time of surgery was 65.6 years (range 15-88 years); 67% of patients were female, and 90.3% were white. At the time of surgery, 129 patients (65.8%) met criteria for CIA, 42 (21.4%) for GCA, 14 (7.1%) for TAK, and 11 (5.6%) met criteria for other systemic inflammatory diseases. During a mean follow-up period of 56.2 months, 19% of CIA patients developed new symptoms, 45% developed new radiographic vascular lesions, 40% underwent additional vascular surgery, and 12% died (n = 9). Eleven of 73 patients (15%) initially classified as having CIA developed features of a systemic disease, most often GCA. CONCLUSION: The majority of patients (66%) with histopathologically proven aortitis have CIA at the time of surgery. CIA patients infrequently report new symptoms over time, but new vascular lesions requiring surgery commonly occur. Serial follow-up including large vessel imaging is strongly advised for all aortitis patients.

Loeys-Dietz syndrome: Intermediate-term outcomes of medically and surgically managed patients.

OBJECTIVES: Loeys-Dietz syndrome (LDS) is an aggressive connective tissue disorder associated with increased risk of aortic dissection and aneurysm rupture at an early age and smaller aortic diameters. We report our experience with LDS to better understand its natural history and treatment outcomes and help establish treatment guidelines. METHODS: We retrospectively reviewed all patients with LDS who underwent medical or surgical treatment at Cleveland Clinic before April 27, 2017. Primary endpoints were postoperative in-hospital morbidity and mortality. Secondary endpoints were aorta-related reoperations and short- and long-term mortality. RESULTS: We identified 53 patients with LDS. Of these, 33 (62%) underwent aortic surgery. Mean age was 39 ± 14 years, and mean maximum aortic diameter was 4.3 cm. There were 2 (6%) deaths after urgent or emergency surgery. Twenty-two patients (67%) required no aortic reoperation; 20 of these had prophylactic surgery. Multiple aortic operations were performed on 11 (33%) patients, 9 of whom experienced aortic dissections. Six patients (18%) required total aortic replacement. Among 19 patients with modified root reimplantation, no aorta- or valve-related complications occurred. Overall, 33 patients underwent 58 aortic and 81 cardiovascular operations, with 1 late death. Kaplan-Meier survival of the aortic-surgery cohort was 89% at 10 years (median follow-up 5.2 years). There were no late deaths in the non-aortic surgery group (20/53; 38%). CONCLUSIONS: Prophylactic aortic surgical outcomes in LDS are excellent. Surgical reintervention remains high, particularly after aortic dissections. Close surveillance of medically managed and postoperative patients and early prophylactic surgery are crucial to avoid aortic catastrophe and achieve a good long-term prognosis.

Cost of Major Complications After Liver Resection in the United States: Are High-volume Centers Cost-effective?

OBJECTIVE: The aim of the study was to estimate the cost of major complications after liver resection and determine whether high-volume (HV) centers are cost-effective. METHODS: From 2002 to 2011, 96,107 cases of liver resection performed in the United States were identified using Nationwide Inpatient Sample. Hospitals were categorized as HV (150+ cases/yr), medium-volume (51-149 cases/yr), and low-volume (LV) (1-50 cases/yr) centers. Multivariable regression analysis identified predictors of cost. Propensity score matching comparing cases with versus without complications and costs of specific complications were estimated. Cost-effectiveness of HV centers was determined by calculating the incremental cost-effectiveness ratio. RESULTS: After propensity score matching, the occurrence of a major complication added $33,855 extra cost, increased mean length of stay by 8.7 [95% confidence interval (CI), 8.4-9] days and increased risk of death by 9.3% (all P < 0.001). The cost of most common complications was wound infection (3.8%, $21,995), renal failure (2.8%, $19,201), respiratory failure (2.7%, $25,169), and hemorrhage (3.3%, $9,180), whereas sepsis (0.8%, $33,009), gastrointestinal bleeding (0.5%, $32,835), fistula (0.2%, $27,079), and foreign body removal (0.1%, $29,404) were most costly, but less frequent. Compared with LV centers, liver resection at HV centers was associated with $5109 (95% CI, 4409-5809, P < 0.001) more cost per case, yet on average 0.54 years (95% CI, 0.23-0.86) longer survival for an incremental cost-effectiveness ratio of $9392. CONCLUSIONS: HV centers were cost-effective at performing liver resection compared with LV centers. After liver resection, complications such as surgical site infection, respiratory failure, and renal failure contributed the most to annual cost burden.

Time to Readmission and Mortality Among Patients Undergoing Liver and Pancreatic Surgery.

BACKGROUND: The impact of time to readmission (TTR) on post-discharge mortality has not been well examined. We sought to define the impact of TTR on postoperative mortality after liver or pancreas surgery. METHODS: A retrospective cohort analysis of liver and pancreas surgical patients was conducted using 2013-2015 Medicare Provider Analysis and Review database. Patients were subdivided into TTR groups: 1-5 days, 6-15, 15-30, 31-60, 61-90, and no readmission. The association of index complication, readmission causes, TTR, and mortality was assessed. RESULTS: Among 18,177 patients, a total of 4485 (24.7%) patients were readmitted within 90 days of discharge. Major causes for readmission differed across TTR groups. Patients readmitted within 1-15 days were more likely to be readmitted for postoperative infection compared with patients who had a late readmission (1-5 days: 63.1% vs. 6-15 days: 65.0% vs. 61-90 days: 39.3%; P < 0.001). In contrast, causes of late readmissions were more likely related to gastrointestinal complications (1-5 days: 28.9% vs. 61-90 days: 39.7%; P < 0.001). Compared with no readmission, 180-day mortality was highest among patients readmitted within 16-30 days (aOR 3.60; 95% CI 2.94-4.41). Among patients with index complications, patients who were readmitted within 1-5 days had a higher risk-adjusted 180-day mortality than late readmission (1-5 days: 37.3% vs. 61-90 days: 27.1%) (P < 0.001). CONCLUSIONS: Among patients who were readmitted, the incidence of mortality increased with TTR up to 60 days after discharge yet decreased thereafter. The relation of TTR and mortality was particularly pronounced among those patients who had an index complication. Future efforts should consider TTR when identifying specific approaches to decrease readmission.

Population level outcomes and costs of single stage colon and liver resection versus conventional two-stage approach for the resection of metastatic colorectal cancer.

BACKGROUND: The objective of the current study was to compare outcomes among patients combined colon (CR) and liver resection (LR) for the treatment of simultaneous colorectal liver metastasis (CRLM) versus patients undergoing two-stage CR and LR. METHODS: Patients undergoing surgery for CRLM between 2004 and 2014 were identified using the Nationwide Inpatient Sample (NIS). Propensity-score matching was used to compare patients undergoing CR + LR with patients undergoing two-stage CR and LR. RESULTS: Among 83,410 patients, CR + LR was performed in 5659 (6.7%), stage C + LR was performed in 5659 (6.7%), while isolated CR and LR was performed in 70,177 (84.0%) and 7574 (9.3%) patients, respectively. The number of patients undergoing CR + LR increased from 423 in 2004 to 580 in 2014 (Δ = +37%). Patients undergoing CR + LR had lower postoperative morbidity (CR + LR vs. two-staged CR and LR: 38.5% vs. 61.2%), shorter LOS (median LOS: 8 days [IQR: 7-12] vs. 14 days [IQR: 10-21]), and lower postoperative mortality (3.1% vs. 5.9%) versus patients undergoing two-stage CR and LR. Compared with patients undergoing two-staged CR and LR, median hospital costs were $13,093 lower for patients undergoing CR + LR (median costs: $36,775 [IQR: 26,416-54,245] vs. $23,682 [IQR: 16,299-32,996]). CONCLUSION: CR + LR was increasingly performed for treatment of CRLM. Compared with two-staged CR and LR, CR + LR was associated with improved outcomes and lower costs.

Variation in the cost-of-rescue among medicare patients with complications following hepatopancreatic surgery.

BACKGROUND: The relationship of expenditures related to rescuing patients from complications and hospital quality has not been well characterized. We sought to examine the relationship between payments for treating post-operative complications after liver and pancreas surgery and hospital quality. METHODS: A retrospective cohort study of patients who underwent hepatopancreatic surgery was performed using claims data from 2013 to 2015 in the Medicare Provider Analysis and Review (MEDPAR) database. Medicare payments for index hospitalization and readmissions, as well as perioperative clinical outcomes were analyzed. Hospitals were stratified using average payments for patients who were rescued from complications (cost-of-rescue). RESULTS: A total of 13,873 patients and 737 hospitals were included in the analyses. Patient characteristics were similar across hospitals. Risk-adjusted rates of overall complications were higher at the highest cost-of-rescue hospitals (relative risk [RR], 1.35, 95% confidence interval [CI] 1.16-1.58), as well as rates of serious complications (RR, 1.78, 95% CI 1.51-2.09), 30-day readmission (RR 1.21 95% CI 1.06-1.39), 90-day mortality (RR, 1.29, 95% CI 1.01-1.64), and rates of failure-to-rescue (RR, 1.50, 95% CI 1.14-1.97). CONCLUSION: Highest cost-of-rescue hospitals demonstrated worse quality metrics, including higher rates of serious complications, failure-to-rescue, 30-day readmission, and 90-day mortality.

Readmission after pancreatic resection: causes, costs and cost-effectiveness analysis of high versus low quality hospitals using the Nationwide Readmission Database.

BACKGROUND: Objectives were to determine the causes of readmission and assess the cost-effectiveness of high (HQ) and low quality (LQ) hospitals in performing pancreatic resection, by using readmission rates as the measure of quality. METHODS: We identified 53,572 pancreatic resection cases from National Readmission Database from 2010 through 2014. Hospitals were risk adjusted and ranked based on readmission. Top 20% HQ hospitals having the lowest readmission rates were compared to the bottom 20% LQ hospitals with the highest readmission rates. RESULTS: The 90-day readmission rate was 27.2% (HQ: 25.7%, LQ: 30.9%, p < 0.001). Compared to LQ, HQ hospitals had lower mortality (2.1% vs 10.2%, p < 0.001) and major complication (10.5% vs 53%, p < 0.001). Major complication during index operation was a major predictor of readmission (RR: 1.6, 95% CI: 1.6-1.7, p < 0.001). The optimal cut point of hospital volume associated with low mortality was 70 or more cases/year. Per year of survival benefit at HQ hospitals, the costs were lower by $9,293 with cost-savings of $6.98 million/year. CONCLUSION: HQ hospitals were cost-effective at performing pancreatic resection and achieved substantial cost-savings by avoiding major complications during index operation and having lower rates of readmissions. Hospital readmission rate is a strong marker of quality of care.

Procedure-Specific Volume and Nurse-to-Patient Ratio: Implications for Failure to Rescue Patients Following Liver Surgery.

BACKGROUND: The effect of various hospital characteristics on failure to rescue (FTR) after liver surgery has not been well examined. We sought to examine the relationship between hospital characteristics and FTR after liver surgery. METHODS: The 2013-2015 Medicare-Provider Analysis and Review (MEDPAR) database was used to identify Medicare beneficiaries who underwent liver surgery. The effect of various hospital characteristics on FTR was compared among the highest mortality hospitals (HMH) and the lowest mortality hospitals (LMH). RESULTS: Among 4902 patients undergoing hepatectomy, patients treated at HMH had a higher risk of FTR (OR 3.08, 95% CI 2.03-4.66). Hospital factors such as total number of beds (OR 0.80, 95% 0.56-1.15), operating rooms (OR 0.81, 95% 0.57-1.14), and overall hospital surgical volume (OR 0.88, 95% 0.61-1.25) were not associated with FTR (all p > 0.05). In contrast, hospitals with a greater nurse-to-patient ratio had a markedly lower risk of FTR following a complication (OR 0.70, 95% CI 0.54-0.91; p = 0.007) (Table 3). As volume of liver operations and nurse-to-patient ratio decreased the risk of FTR increased (p > 0.001). After risk-adjusting for patient characteristics, both the effect of surgical volume (adjusted OR 0.66, 95% CI 0.46-0.94; p = 0.022) and nurse-to-patient ratio (adjusted OR 0.68, 95% CI 0.51-0.90; p = 0.008) remained strongly associated with FTR. CONCLUSION: FTR rates varied considerably among hospital performing hepatectomy. Higher procedure-specific hepatectomy volume, as well as a higher nurse-to-patient ratio, accounted for a reduction in the FTR rates. These data highlight the importance of not only procedure volume, but also adequate nurse staffing in reducing FTR and improving mortality following complex procedures such as hepatectomy.

Trends and Outcomes of Cardiovascular Surgery in Patients With Opioid Use Disorders.

Importance: Persistent opioid use is currently a major health care crisis. There is a lack of knowledge regarding its prevalence and effect among patients undergoing cardiac surgery. Objective: To characterize the national population of cardiac surgery patients with opioid use disorder (OUD) and compare outcomes with the cardiac surgery population without OUD. Design, Setting, and Participants: In this retrospective population-based cohort study, more than 5.7 million adult patients who underwent cardiac surgery (ie, coronary artery bypass graft, valve surgery, or aortic surgery) in the United States were included. Pregnant patients were excluded. Propensity matching was performed to compare outcomes between cardiac surgery patients with OUD (n = 11 359) and without OUD (n = 5 707 193). The Nationwide Inpatient Sample database was queried from January 1998 to December 2013. Data were analyzed in January 2018. Exposures: Persistent opioid use and/or dependence. Main Outcomes and Measures: In-hospital mortality, complications, length of stay, costs, and discharge disposition. Results: Among the 5 718 552 included patients, 3 887 097 (68.0%) were male; the mean (SD) age of patients with OUD was 47.67 (13.03) years and of patients without OUD was 65.53 (26.14) years. The prevalence of OUD among cardiac surgery patients was 0.2% (n = 11 359), with an 8-fold increase over 15 years (0.06% [262 of 437 641] in 1998 vs 0.54% [1425 of 263 930] in 2013; difference, 0.48%; 95% CI of difference, 0.45-0.51; P < .001). Compared with patients without OUD, patients with OUD were younger (mean [SD] age, 48 [0.30] years vs 66 [0.05] years; P < .001) and more often male (70.8% vs 68.0%; P < .001), black (13.7% vs 4.8%), or Hispanic (9.1% vs 4.8%). Patients with OUD more commonly fell in the first quartile of median income (30.7% vs 17.1%; P < .001) and were more likely to be uninsured or Medicaid beneficiaries (48.6% vs 7.7%; P < .001). Valve and aortic operations were more commonly performed among patients with OUD (49.8% vs 16.4%; P < .001). Among propensity-matched pairs, the mortality was similar between patients with vs without OUD (3.1% vs 4.0%; P = .12), but cardiac surgery patients with OUD had an overall higher incidence of major complications (67.6% vs 59.2%; P < .001). Specifically, the risks of blood transfusion (30.4% vs 25.9%; P = .002), pulmonary embolism (7.3% vs 3.8%; P < .001), mechanical ventilation (18.4% vs 15.7%; P = .02), and prolonged postoperative pain (2.0% vs 1.2%; P = .048) were significantly higher. Patients with OUD also had a significantly longer length of stay (median [SE], 11 [0.30] vs 10 [0.22] days; P < .001) and cost significantly more per patient (median [SE], $49 790 [1059] vs $45 216 [732]; P < .001). Conclusions and Relevance: The population of patients with persistent opioid use or opioid dependency undergoing cardiac surgery has increased over the past decade. Cardiac surgery in patients with OUD is safe but is associated with higher complications and cost. Patients should not be denied surgery because of OUD status but should be carefully monitored postoperatively for complications.

Trends in centralization of surgical care and compliance with National Cancer Center Network guidelines for resected cholangiocarcinoma.

BACKGROUND: A retrospective study was performed to characterize trends in centralization of care and compliance with National Comprehensive Cancer Network (NCCN) guidelines for resected cholangiocarcinoma (CCA), and their impact on overall survival (OS). METHODS: Using the National Cancer Database (NCDB) 2004-2015 we identified patients undergoing resection for CCA. Receiver Operating Characteristic (ROC) analyses identified time periods and hospital volume groups for comparison. Propensity score matching provided case-mix adjusted patient cohorts. Cox hazard analysis identified risk factors for OS. RESULTS: Among the 40,338 patients undergoing resection for CCA, the proportion of patients undergoing surgery at high volume hospitals increased over time (25%-44%, p < 0.001), while the proportion of patients undergoing surgery at low volume hospitals decreased (30%-15%, p < 0.001). Using ROC analyses, a hospital volume of 14 operations/year was the most sensitive and specific value associated with mortality. Surgery at high volume hospitals [HR] = 0.92, 95% CI: 0.88-0.97, p < 0.001) and receipt of care compliant with NCCN guidelines (HR = 0.87, 95% CI: 0.83-0.91, p < 0.001) were independently associated with improved OS. CONCLUSIONS: Both centralization of surgery for CCA to high volume hospitals and increased compliance with NCCN guidelines were associated with significant improvements in overall survival.

The Cost of Failure: Assessing the Cost-Effectiveness of Rescuing Patients from Major Complications After Liver Resection Using the National Inpatient Sample.

OBJECTIVE: To estimate the cost of rescue and cost of failure and determine cost-effectiveness of rescue from major complications at high-volume (HV) and low-volume (LV) centers METHODS: Ninety-six thousand one hundred seven patients undergoing liver resection were identified from the Nationwide Inpatient Sample (NIS) between 2002 and 2011. The incremental cost of rescue and cost of FTR were calculated. Using propensity-matched cohorts, a cost-effectiveness analysis was performed to determine the incremental cost-effectiveness ratio (ICER) between HV and LV hospitals. RESULTS: Ninety-six thousand one hundred seven patients were identified in NIS. The overall mortality was 2.3% and was lowest in HV centers (HV 1.4% vs. MV 2.1% vs. LV 2.6%; p < 0.001). Major complications occurred in 14.9% of hepatectomies and were comparable regardless of volume (HV 14.2% vs. MV 14.3% vs. LV 15.4%; p < 0.001). The FTR rate was substantially lower among HV centers (HV 7.7%, MV 11%, LV 12%; p < 0.001). At a willingness to pay benchmark of $50,000 per year of life saved, both HV (ICER = $3296) and MV (ICER = $4182) centers were cost-effective at rescuing patients from a major complication compared to LV hospitals. CONCLUSION: Not only was FTR less common at HV hospitals, but the management of most major complications was cost-effective at higher volume centers.

Synergistic Effects of Perioperative Complications on 30-Day Mortality Following Hepatopancreatic Surgery.

BACKGROUND: Data on the interaction effect of multiple concurrent postoperative complications relative to the risk of short-term mortality following hepatopancreatic surgery have not been reported. The objective of the current study was to define the interaction effect of postoperative complications among patients undergoing HP surgery on 30-day mortality. METHODS: Using the ACS-NSQIP Procedure Targeted Participant Use Data File, patients who underwent HP surgery between 2014 and 2016 were identified. Hazard ratios (HRs) for 30-day mortality were estimated using Cox proportional hazard models. Two-way interaction effects assessing combinations of complications relative to 30-day mortality were calculated using the relative excess risk due to interaction (RERI) in separate adjusted Cox models. RESULTS: Among 26,824 patients, 10,886 (40.5%) experienced at least one complication. Mortality was higher among patients who experienced at least one complication versus patients who did not experience a complication (3.0 vs 0.1%, p < 0.001). The most common complications were blood transfusion (16.9%, n = 4519), organ space infection (12.2%, n = 3273), and sepsis/septic shock (8.2%, n = 2205). Combinations associated with additive effect on mortality included transfusion + renal dysfunction (RERI 12.3, 95% CI 5.2-19.4), pulmonary dysfunction + renal dysfunction (RERI 60.9, 95% CI 38.6-83.3), pulmonary dysfunction + cardiovascular complication (RERI 144.1, 95% CI 89.3-199.0), and sepsis/septic shock + renal dysfunction (RERI 11.5, 95% CI 4.4-18.7). CONCLUSION: Both the number and specific type of complication impacted the incidence of postoperative mortality among patients undergoing HP surgery. Certain complications interacted in a synergistic manner, leading to a greater than expected increase in the risk of short-term mortality.

Variation in Medicare Payments and Reimbursement Rates for Hepatopancreatic Surgery Based on Quality: Is There a Financial Incentive for High-Quality Hospitals?

BACKGROUND: To better define the financial impact of high-quality care for payers and hospitals, we compared outcomes and Medicare payments between high-quality (HQ) and low-quality (LQ) hospitals after hepatopancreatic surgery. STUDY DESIGN: Between 2013 through 2015, a total of 15,874 Medicare beneficiaries underwent hepatopancreatic surgery. Using the entire cohort, multivariable logistic regression was performed to categorize hospitals into quintiles based on the probability of experiencing a major complication; HQ (bottom 20%) and LQ (top 20%) hospitals were identified. Only HQ and LQ hospitals were included in the final propensity matching to compare payments. Major complication was defined as a complication associated with a length of stay of >75th percentile. Incremental payment and cost of complication were estimated using multivariable linear regression. RESULTS: Major complications occurred in 9.7% (n = 309 of 3,182) at HQ hospitals compared with 20% (n = 625 of 3,130) at LQ hospitals (p < 0.001). The incremental increased payment associated with major complication was $29,640, which was lower than the incremental hospital cost of $42,935. The Medicare reimbursement rate was also 6% lower at both HQ and LQ hospitals when a major complication occurred vs not; however, HQ hospitals had a 3% higher reimbursement rate compared with LQ hospitals when a major complication did not occur (p = 0.002). Mean unadjusted Medicare payment was lower at HQ hospitals by $5,165 per patient vs LQ hospitals (p < 0.001), largely because HQ hospitals had a lower overall incidence of major complications (n = 315 vs n = 625). By having 310 fewer patients with a major complication, HQ hospitals collectively achieved $3.1 million/year in Medicare savings. CONCLUSIONS: High-quality hospitals are able to achieve substantial Medicare savings by avoiding major complications. Occurrence of major complications was associated with lower Medicare reimbursement rates at both HQ and LQ hospitals vs when no complications occurred.

Impact of Post-Discharge Disposition on Risk and Causes of Readmission Following Liver and Pancreas Surgery.

BACKGROUND: The relationship between the post-discharge settings and the risk of readmission has not been well examined. We sought to identify the association between discharge destinations and readmission rates after liver and pancreas surgery. METHODS: The 2013-2015 Medicare-Provider Analysis and Review (MEDPAR) database was reviewed to identify liver and pancreas surgical patients. Patients were subdivided into three groups based on discharge destination: home/self-care (HSC), home with home health assistance (HHA), and skilled nursing facility (SNF). The association between post-acute settings, readmission rates, and readmission causes was assessed. RESULTS: Among 15,141 liver or pancreas surgical patients, 60% (n = 9046) were HSC, 26.9% (n = 4071) were HHA, and 13.4% (n = 2024) were SNF. Older, female patients and patients with ≥ 2 comorbidities, ≥ 2 previous admissions, an emergent index admission, an index complication, and ≥ 5-day length of stay were more likely to be discharged to HHA or SNF compared to HSC (all P < 0.001). Compared to HSC, HHA and SNF patients had a 34 and a 67% higher likelihood of 30-day readmission, respectively. The HHA and SNF settings were also associated with a 33 and a 69% higher risk of 90-day readmission. There was no association between discharge destination and readmission causes. CONCLUSION: Among liver and pancreas surgical patients, HHA and SNF patients had a higher risk of readmission within 30 and 90 days. There was no difference in readmission causes and discharge settings. The association between discharge setting and the higher risk of readmission should be further evaluated as the healthcare system seeks to reduce readmission rates after surgery.
