Adding Patient-Reported Outcomes to the American College of Surgeons National Surgical Quality Improvement Program: Results of the First 33,842 Patients from 65 Hospitals.

OBJECTIVES: To investigate the initial set of patient-reported outcomes (PROs) in the ACS NSQIP and their associations with 30-day surgical outcomes. BACKGROUND: PROs provide important information that can be used to improve routine care and facilitate quality improvement. The ACS conducted a demonstration project to capture PROs into the NSQIP to complement clinical data. METHODS: From 2/2020-3/2023, 65 hospitals collected PROMIS measures assessing global health, pain interference, fatigue, and physical function from patients accrued into the NSQIP. Using multivariable mixed regression, we compared the scores of patients with and without 30-day complications and further analyzed scores exceeding one standard deviation (1-SD) worse than national benchmarks. RESULTS: Overall, 33842 patients completed the PROMIS measures a median 58 days (IQR 47-72) postoperatively. Among patients without complications (n=31210), 33.9% had PRO scores 1-SD worse than national benchmarks. Patients with complications were 1.7-times more likely to report worse PROs (95% CI 1.6-1.8). Patients with complications had lower scores for global physical health (adjusted mean difference [AMD] 2.6, 95% CI 2.2-3.0), lower for global mental health (AMD 1.8, 95% CI 1.4-2.2), higher for pain interference (AMD 2.4, 95% CI 2.0-2.8), higher fatigue (AMD 2.7, 95% CI 2.3-3.1), and lower physical function (AMD 3.2, 95% CI 2.8-3.5). CONCLUSIONS: Postoperative complications negatively affect multiple key dimensions of patients' health-related quality of life. PROs were well below national benchmarks for many patients, even among those without complications. Identifying solutions to improve PROs after surgery thus remains a tremendous quality opportunity.

Patient-Reported Outcome Measures Within a National Multispecialty Surgical Quality Improvement Program.

Importance: Patient-reported outcome measures (PROMs) are increasingly recognized for their ability to promote patient-centered care, but concerted health information technology (HIT)-enabled PROM implementations have yet to be achieved for national surgical quality improvement. Objective: To evaluate the feasibility of collecting PROMs within a national surgical quality improvement program. Design, Setting, and Participants: This was a pragmatic implementation cohort study conducted from February 2020 to March 2023. Hospitals in the US participating in the American College of Surgeons National Surgical Quality Improvement Program and their patients were included in this analysis. Exposures: Strategies to increase PROM collection rates were identified using the Institute for Healthcare Improvement (IHI) Framework for Spread and the Consolidated Framework for Implementation Research and operationalized with the IHI Model for Improvement's Plan-Do-Study-Act (PDSA) cycles. Main Outcomes and Measures: The primary goal was to accrue more than 30 hospitals and achieve collection rates of 30% or greater in the first 3 years. Logistic regression was used to identify hospital-level factors associated with achieving collection rates of 30% or greater and to identify patient-level factors associated with response to PROMs. Results: At project close, 65 hospitals administered PROMs to 130 365 patients (median [IQR] age, 60.1 [46.2-70.0] years; 77 369 female [59.4%]). Fifteen PDSA cycles were conducted to facilitate implementation, primarily targeting the Consolidated Framework for Implementation Research domains of Inner Setting (ie, HIT platform) and Individuals (ie, patients). The target collection rate was exceeded in quarter 3 (2022). Fifty-eight hospitals (89.2%) achieved collection rates of 30% or greater, and 9 (13.8%) achieved collection rates of 50% or greater. The median (IQR) maximum hospital-level collection rate was 40.7% (34.6%-46.7%). The greatest increases in collection rates occurred when both email and short-message service text messaging were used, communications to patients were personalized with their surgeon's and hospital's information, and the number of reminders increased from 2 to 5. No identifiable hospital characteristic was associated with achieving the target collection rate. Patient age and insurance status contributed to nonresponse. Conclusions and Relevance: Results of this cohort study suggest that the large-scale electronic collection of PROMs into a national multispecialty surgical registry was feasible. Findings suggest that HIT platform functionality and earning patient trust were the keys to success; although, iterative opportunities to increase collection rates and address nonresponse remain. Future work to drive continuous surgical quality improvement with PROMs are ongoing.

Non-Operative, Active Surveillance of Larger Malignant and Suspicious Thyroid Nodules.

CONTEXT: Active surveillance for papillary thyroid cancer (PTC) meeting criteria for surgical resection is uncommon. Which patients may prove reasonable candidates for this approach is not well defined. OBJECTIVE: To examine the feasibility and safety of active surveillance for patients with known or suspected intrathyroidal PTC up to 4cm in diameter. DESIGN, SETTING, AND PARTICIPANTS: Retrospective review of all consecutive patients who underwent non-operative active surveillance of suspicious or malignant thyroid nodules over a 20-year period from 2001-2021. We included patients with an initial US-FNA confirming either: a) Bethesda 5 or 6 cytology or, b) a "suspicious" AFIRMA molecular test. The primary outcomes and measures included the rate of adverse oncologic outcomes (mortality and recurrence), as well as the cumulative incidence of size/volume growth. RESULTS: Sixty-nine patients were followed with active surveillance for 1 year or longer (average 55 months), with 26 patients (38%) having nodules ≥ 2 cm. No patients were found to develop new incident occurrence of lymph node or distant metastasis. One patient however, demonstrated concern for progression to a dedifferentiated cancer on repeat core biopsy 17 years after initial start non-operative selection. 21% of patients had an increase in maximum diameter more than 3 mm, and volume increase ≥50% was noted in 25% of patients. Thirteen patients ultimately underwent delayed (rescue) surgery, and no disease recurrence was noted after such treatment. Age and initial nodule size were not predictors of nodule growth. CONCLUSIONS: These data expand consideration of active surveillance of papillary thyroid carcinoma in select patients with intrathyroidal suspected malignancy >1cm in diameter. Rescue surgery, if required at a later timepoint, appears effective.

Sex differences in patients with primary hyperparathyroidism.

BACKGROUND: Differences in presenting symptoms of primary hyperparathyroidism and outcomes of parathyroidectomy between sexes have been described, but whether these can be assessed by perioperative use of a validated tool, such as the Pasieka Parathyroidectomy Assessment Score, is unknown. METHOD: All patients with primary hyperparathyroidism were asked to complete symptom assessment at the preoperative and postoperative visits. The assessment included a query for 13 Pasieka Parathyroidectomy Assessment Score parameters evaluated using a visual analog scale as described by Pasieka (summative score 0-1,300), and general quality of life and wellness. A review of a prospectively maintained database of primary hyperparathyroidism patients (January 2016-December 2019) was performed, and those who had a 6-month cure after initial parathyroidectomy were included. RESULTS: The study cohort was mostly women (77%, 541/701). The median preoperative Pasieka Parathyroidectomy Assessment Score was higher in women (155, 0-1,190) than in men (80.5, 0-855, P < .001), although there were similar rates of asymptomatic primary hyperparathyroidism (Pasieka Parathyroidectomy Assessment Score = 0, 12.5% vs 7%, P = .042). After curative parathyroidectomy, women reported a substantial reduction in symptomatology, with Pasieka Parathyroidectomy Assessment Score declining by 35% at initial postoperative visit (median, 155 vs 100, P < .001), further decreasing to 48% by 6 months (155 vs 80, P < .001). The Pasieka Parathyroidectomy Assessment Score in men did change but to a much smaller degree at both the initial postoperative visit (80.5 vs 70; P = .036) and at 6 months (80.5 vs 57.5; P = .048). CONCLUSION: When assessed with the Pasieka Parathyroidectomy Assessment Score, improvement in symptoms was clearly demonstrated for women after curative parathyroidectomy. Whether symptom improvement also occurs in men is less apparent but may be due to disparities in the development and validation of outcomes tools in general.

Patient-Reported Outcomes and Surgical Quality.

Delivering high-quality surgical care requires knowing how best to define and measure quality in surgery. Patient-reported outcomes (PROs) enable surgeons, health care systems, and payers to understand meaningful health outcomes from the patient's perspective and can be measured using patient-reported outcome measures (PROMs). As a result, there is much interest in using PROMs in routine surgical care, to guide quality improvement and to inform reimbursement pay structures. This chapter defines PROs and PROMs, differentiates PROMs from other quality measures such as patient-reported experience measures, describes PROMs in the context of routine clinical care, and provides an overview of interpreting PROM data. This chapter also describes how PROMs may be applied to quality improvement and value-based reimbursement in surgery.

Molecular Testing Predicts Incomplete Response to Initial Therapy in Differentiated Thyroid Carcinoma Without Lateral Neck or Distant Metastasis at Presentation: Retrospective Cohort Study.

Background: Molecular testing (MT) is emerging as a potential prognostic factor that can be available before treatment of differentiated thyroid carcinoma begins. Among patients eligible for either lobectomy or total thyroidectomy as their initial therapy, our study aims were to assess (1) if conventionally available preoperative factors are associated with incomplete response to initial therapy, and (2) if MT results can be a surrogate for the ATA Risk Stratification System (RSS) to estimate risk of recurrence. Methods: The data of consecutive thyroid cancer patients without preoperative lateral neck disease or distant metastasis who underwent index thyroidectomy between November 1, 2017 and October 31, 2021 were reviewed. Logistic regression models including preoperative variables such as MT and/or the postoperatively available RSS were constructed to predict disease recurrence, either structural or biochemical. Model discrimination using the c-statistic and goodness-of-fit test were compared. Results: Among 945 patients studied, 50 (5.2%) recurred with 18-month median follow-up. Recurrences were detected in 17 (2.9%), 20 (6.7%), and 13 (22.8%) patients with RSS-low, -intermediate, and -high cancers, respectively (p < 0.001). In multivariable analysis, only tumor size was associated with recurrence (odds ratio [OR] 1.3, 95% confidence interval [CI] 1.1-1.5). In a different model analyzing 440 (46.6%) patients with available MT results, recurrence was associated with both larger tumor size (OR 1.4 [95% CI 1.1-1.8]) and MT results (p < 0.001). Including MT improved the c-statistic by 27%, which was statistically no different than the model incorporating only the RSS (p = 0.15). Conclusions: Disease recurrence was observed across all ATA RSS categories in short-term follow-up, and tumor size was the only conventional preoperative factor associated with recurrence. When MT results were incorporated, they not only improved predictive ability beyond tumor size alone, but also yielded similar ability as the gold standard ATA RSS. Thus, MT results might aid the development of novel preoperative risk stratification algorithms.

Imaging of Small-Bowel Neuroendocrine Neoplasms: AJR Expert Panel Narrative Review.

Neuroendocrine neoplasms (NENs) of the small bowel are typically slow-growing lesions that remain asymptomatic until reaching an advanced stage. Imaging modalities for lesion detection, staging, and follow-up in patients with known or suspected NEN include CT enterography, MR enterography, and PET/CT using a somatostatin receptor analog. FDG PET/CT may have a role in the evaluation of poorly differentiated NENs. Liver MRI, ideally with a hepatocyte-specific contrast agent, should be used in the evaluation of hepatic metastases. Imaging informs decisions regarding both surgical approaches and systematic therapy (specifically, peptide receptor radionuclide therapy). This AJR Expert Panel Narrative Review describes the multimodality imaging features of small-bowel NENs; explores the optimal imaging modalities for their diagnosis, staging, and follow-up; and discusses how imaging may be used to guide therapy.

Changes in thyroid nodule cytology rates after institutional implementation of the Thyroid Imaging Reporting and Data System.

BACKGROUND: The American College of Radiology Thyroid Imaging Reporting and Data System for ultrasound classification of malignancy risk was developed to better triage thyroid nodules for fine-needle aspiration biopsy. To examine further, we compared thyroid cytologic classification rates in nodules before and after institutional Thyroid Imaging Reporting and Data System implementation. METHODS: Cytology diagnoses by Bethesda criteria (categories I-VI) from January 2014 to October 2021 were retrieved; observed changes in yearly category frequency were analyzed by linear regression; and pooled cohorts of pre- (2014-2018) and post-Thyroid Imaging Reporting and Data System (2019-2021) cytology call rates were compared. RESULTS: Overall, 7,413 cytologic specimens were included (range/year 715-1,444). From 2014 to 2021, the proportion of benign (Bethesda category II) diagnosis per year declined stepwise from 49.7% to 19.4%, and atypia of undetermined significance/follicular lesion of undetermined significance (Bethesda category III) increased sequentially from 21.3% to 51.5%. Between 2014 and 2021, Bethesda category III diagnosis increased on average by 4.8% per year (95% confidence internal, 3.29-5.54; P < .001) and Bethesda category II results decreased on average by 4.4% per year (95% confidence interval, 6.29-3.42; P < .001). When comparing pre- and post-Thyroid Imaging Reporting and Data System, the proportion of Bethesda category II cytology results decreased (43.1% vs 21%; P = .001) while Bethesda category III (28.3% vs 47.7%; P = .002) and Bethesda category V (1.1% vs 1.7%; P = .015) results increased. CONCLUSION: After implementation of American College of Radiology Thyroid Imaging Reporting and Data System ultrasound criteria, we observed a 2.5-fold decline in the rate of benign cytology and an increase in the proportion of atypia of undetermined significance/follicular lesion of undetermined significance results.

Association of comprehensive thyroid cancer molecular profiling with tumor phenotype and cancer-specific outcomes.

BACKGROUND: Molecular testing improves the diagnostic accuracy of thyroid cancer. Whether specific molecular testing results are associated with tumor phenotype or provide prognostic information needs further delineation. METHODS: Consecutive thyroid cancer patients after index thyroidectomy with ThyroSeq version 3 (Rye Brook, NY) molecular testing obtained on preoperative fine-needle aspiration or thyroidectomy specimens from patients with thyroid cancer were categorized into 3 molecular risk groups based on detected mutations, fusions, copy number alterations, and/or gene expression alterations and correlated with histopathology and recurrence, defined as biochemical or structural. RESULTS: Of 578 patients, 49.9%, 37.5%, and 12.6% had molecular risk group-low, molecular risk group-intermediate, and molecular risk group-high cancers, respectively. With a median 19-month follow-up, 9.1% patients recurred. Compared with molecular risk group-low, molecular risk group-intermediate cancers were diagnosed in younger patients and more often had microscopic extrathyroidal extension, involved margins, and nodal disease. Compared with molecular risk group-intermediate, molecular risk group-high cancers were diagnosed in older patients and more often had gross extrathyroidal extension and vascular invasion. In multivariable analysis, recurrence was more likely in molecular risk group-high cancers than in molecular risk group-intermediate (hazard ratio = 4.0; 95% confidence interval, 1.9-8.6; P < .001) and more likely in molecular risk group-intermediate than in molecular risk group-low (hazard ratio = 5.0; 95% confidence interval, 2.0-12.5; P < .001). CONCLUSION: Using modern comprehensive genotyping, the genetic profile of thyroid cancers can be categorized into 3 novel molecular risk groups that were associated with histopathologic phenotype and recurrence in short-term follow-up.

Scaling and spreading the electronic capture of patient-reported outcomes using a national surgical quality improvement programme: a feasibility study protocol.

INTRODUCTION: Patient-reported outcomes (PROs) are important for research, patient care and quality assessment; however, large-scale collection among the US surgical patient population has been limited. A structured implementation and dissemination programme focused on electronic PRO collection could improve the use of PROs data to improve surgical care. This study aims to (1) evaluate the feasibility of PRO collection among a larger volume of surgical patients through the stepwise implementation of PRO collection processes in a sample of American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) hospitals; (2) identify best practices and barriers to PRO collection through qualitative study of participating hospitals and patients; and (3) evaluate the utility of PROs at detecting differences in the quality of care among surgical patients. METHODS AND ANALYSIS: ACS NSQIP-participating hospitals are being recruited, and patients at participating hospitals who undergo elective surgical procedures receive invitations via e-mail or short message service 'text'message to complete PROs after surgery. Validated PRO measures which evaluate physical and mental health-related quality of life, pain, fatigue, physical function and shared decision-making were selected. The scalability of PRO collection will be assessed by site enrolment, patient accrual and response rates. Qualitative interviews and focus groups will be performed with patients and hospital personnel to identify best practices and barriers to successful enrolment and PRO collection. Multivariable hierarchical regression models will be used to evaluate the distinctness of PROs from clinical outcomes captured in ACS NSQIP and the ability of PROs to detect differences in hospital performance. ETHICS AND DISSEMINATION: This study was reviewed by the Advarra Institutional Review Board (IRB) and deemed to be exempt from IRB oversight. Findings will be disseminated through peer-reviewed manuscripts, reports and presentations.

Long-Term Outcomes for Patients with Multiple Endocrine Neoplasia Type 1 and Duodenopancreatic Neuroendocrine Neoplasms.

BACKGROUND: Liver metastasis from duodenopancreatic neuroendocrine neoplasms (DP-NENs) is a major cause of mortality in multiple endocrine neoplasia type 1 (MEN1) patients, yet much of their natural history is unknown. METHODS: This longitudinal, retrospective cohort study analyzed all MEN1 patients with imageable functional (F) and nonfunctional (NF) DP-NENs (1990-2021) for liver metastasis-free survival (LMFS) and overall survival (OS). RESULTS: Of 138 patients, 85 (61.6%) had imageable DP-NENs (28 F, 57 NF), and the mean largest tumor size was 1.8 ± 1.4 cm. Multifocality was present in 32 patients (37.7%). Surgery was performed for 49 patients (57.7%). During an 11-year median follow-up period (IQR, 6-17 years), 23 (27.1%) of the patients had liver metastasis, and 19 (22.4%) patients died. Death was attributed to liver metastasis in 60% of cases. The patients with F-DP-NENs versus NF-DP-NENs more often had liver metastasis (46.4% vs. 15.8%; p = 0.002) but had similar 10-year LMFS (80.9 vs. 87.0%; p = 0.44) and OS (82.7 vs. 94.3%; p = 0.69). The patients with NF-DP-NENs had surgery when their tumors were larger (p < 0.001). Tumor size was not associated with liver metastasis (p = 0.89). The average growth rate was 0.04 cm/year (SE, 0.02 cm/year; p = 0.01) during active surveillance for NF-DP-NENs (n = 38). Liver metastasis developed in four patients with tumors smaller than 2 cm. The risk of liver metastasis was independent of surgery (hazard ratio [HR], 0.78; 95% confidence interval [CI], 0.21-2.93; p = 0.72) and death (HR, 0.51; 95% CI, 0.08-3.06; p = 0.46). CONCLUSIONS: Although the observed outcomes in this study were better than historical data, small NF-DP-NENs still developed liver metastasis and liver metastasis remains a major cause of death. These results suggest that size as a sole criterion for surgery may be insufficient to predict tumor behavior.

Performance of a Multigene Genomic Classifier in Thyroid Nodules with Suspicious for Malignancy Cytology.

Background: Molecular testing is increasingly used to refine the probability of cancer and assess recurrence risk in thyroid nodules with Bethesda III/IV fine needle aspiration (FNA) cytology. However, limited data exist for Bethesda V (suspicious for malignancy [SFM]) samples. This study evaluated the performance of ThyroSeq v3 (TSv3) in thyroid nodules with SFM cytology. Methods: In this single-institution retrospective cohort study, consecutive thyroid FNA samples diagnosed as SFM with TSv3 testing and known surgical outcome were identified. Clinical, pathology, and molecular findings were reviewed. The TSv3 Cancer Risk Classifier was used to determine molecular risk groups (MRGs). For test-negative cases diagnosed as cancer/noninvasive follicular thyroid neoplasm with papillary-like nuclear features, TSv3 was performed on the resected tumors. Results: Among 128 SFM samples studied, 100 (78.1%) were TSv3 positive, and 28 (21.9%) were negative. The cancer prevalence on surgery was 82.8%. Among test-positive samples, 95% were malignant and 5% benign. Among test-negative samples, 17 (60.7%) were benign and 11 (39.3%) malignant. Overall, TSv3 had a sensitivity of 89.6% (confidence interval; CI 82.4-94.1) and a specificity of 77.3% (CI 56.6-89.9). For a cancer prevalence of 50-75% expected in SFM cytology by the Bethesda system, the negative predictive value was expected to range from 71.2% to 88.1% and the positive predictive value from 79.8% to 92.2%. Among test-positive nodules, 20% were MRG-Low (mostly RAS-like alterations), 66% MRG-Intermediate (mostly BRAF-like alterations), and 14% MRG-High. Among patients with cancer, 65 (61.3%) were American Thyroid Association low risk, 25 (23.6%) intermediate risk, and 6 (5.7%) high risk. During the mean follow-up of 51.2 months (range: <1 to 470 months), 12 (13.0%) patients had disease recurrence, which was more common in MRG-High (54.6%) compared with MRG-Intermediate (9.5%) and MRG-Low (0%) cancers (p < 0.001). Upon reexamining tumors with false-negative results, half of evaluable cases had alterations likely missed due to limiting FNA sampling, and the remainder represented low-risk tumors. Potentially targetable alterations were identified in 10 samples. Conclusions: In this large series of SFM thyroid nodules, TSv3 further improved cancer prediction and detected RAS-like, BRAF-like, high-risk, and potentially targetable alterations, all of which may inform more optimal patient management. MRGs were associated with recurrence-free survival, offering potential preoperative cancer risk stratification.

Association of robotic approach with patient-reported outcomes after pancreatectomy: a prospective cohort study.

BACKGROUND: Robotic-assisted pancreatectomy continues to proliferate despite limited evidence supporting its benefits from the patient's perspective. We compared patient-reported outcomes (PROs) between patients undergoing robotic and open pancreatectomies. METHODS: PROs, measured with the FACT-Hep, FACT-G, and HCS, were assessed in the immediate postoperative (i.e., preoperative to discharge) and recovery (i.e., discharge to three months postoperative) periods. Linear mixed models estimated the association of operative approach on PROs. Minimally important differences (MIDs) were also considered. RESULTS: Among 139 patients, 105 (75.5%) underwent robotic pancreatectomies. Compared to those who underwent open operations, those who underwent robotic operations experienced worse FACT-Hep scores that were both statistically and clinically significant (mean difference [MD] 8.6 points, 95% CI 1.0-16.3). Declines in FACT-G (MD 4.3, 95% CI -1.0 to 9.6) and HCS (MD 4.3, 95% CI 0.8-7.9) scores appeared to contribute equally in both operative approaches to the decline in total FACT-Hep score. Patients who underwent robotic versus open operations both statistically and clinically significantly improved due to improvements in HCS (MD 6.1, 95% CI 2.3-9.9) but not in FACT-G (MD 1.2, 95% CI - 5.1-7.4). CONCLUSION: The robotic approach to pancreas surgery might offer, from the patient's perspective, greater improvement in symptoms over the open approach by three months postoperatively.

Small bowel neuroendocrine neoplasm: what surgeons want to know.

Neuroendocrine neoplasms of the small bowel are a diverse group of tumors with a broad spectrum of imaging findings and clinical implications. Most tumors originate in close proximity to the ileocecal valve and most commonly metastasize to the mesentery and liver. This review will highlight the imaging findings of primary and metastatic small bowel neuroendocrine neoplasm that are most relevant to the surgical team.

An interdisciplinary approach to safe opioid prescribing and administration for surgical patients at an academic medical center.

AIM AND OBJECTIVES: To explore and understand the current practice, perceptions, and knowledge of general surgery trainees, advanced practice providers, and surgical nurses regarding opioid prescribing and administration. To this end, a novel opioid education and training was introduced to educate these practitioners on safe opioid practices in surgical patients. BACKGROUND: National awareness of the opioid epidemic has increased significantly in the last several years. However, there remain a disturbingly high number of opioid prescriptions written in the US indicating a need for improved provider and nurse education. This involves increasing awareness and understanding of national guidelines as well as implementing multi-modal therapy to treat pain. DESIGN: Pre-post-intervention quality improvement project. METHODS: An opioid education and training involving a morphine equivalent daily dosing calculator in the electronic medical record was provided to 26 surgical trainees, eight advanced practice providers and 97 surgical nurses in November 2019. Perceptions, current practice and knowledge were measured using a pre- and post-intervention survey (SQUIRE checklist). RESULTS: The survey results showed a positive clinical change in perception of opioid use in surgical patients following the intervention and a modest decrease in the average morphine equivalent daily dosing at discharge in general and transplant surgery patients. CONCLUSIONS: Effective pain management for surgical patients must be individualised. Safe opioid prescribing should involve an interdisciplinary approach with all members of the team undergoing assessment of their opioid knowledge and prescribing habits, easily accessible training tools and opioid calculators in the electronic medical record. RELEVANCE TO CLINICAL PRACTICE: Our initiative may provide useful information to settings that replicate use of a morphine equivalent daily dosing calculator in the electronic medical record. Utilisation of safe opioid prescribing tools in the electronic medical record and continuing education for providers and nurses can help ensure the safety of surgical patients.

A NSQIP-based randomized clinical trial evaluating choice of prophylactic antibiotics for pancreaticoduodenectomy.

Surgical site infection after pancreaticoduodenectomy is often caused by pathogens resistant to standard prophylactic antibiotics, suggesting that broad-spectrum antibiotics may be more effective prophylactic agents. This article describes the rationale and methodology underlying a multicenter randomized trial evaluating piperacillin-tazobactam compared with cefoxitin for surgical site infection prevention following pancreaticoduodenectomy. As the first US randomized surgical trial to utilize a clinical registry for data collection, this study serves as proof of concept for registry-based clinical trials.

Benchmarking Perioperative Outcomes of Cytoreductive Surgery for Cancer: Implications for Quality Measurement.

BACKGROUND: Understanding variation and heterogeneity in practice patterns allows programs to develop effective strategies to improve patient outcomes. Cytoreductive surgery is a potentially highly morbid operation that could benefit from systematic assessments directed towards quality improvement. We describe the hospital-level variation and benchmarks for programs performing cytoreductive surgery. PATIENTS AND METHODS: Cytoreductive and tumor debulking operations with or without hyperthermic intraperitoneal chemotherapy performed for cancer between January 1, 2013 and June 30, 2018 were identified in the American College of Surgeons National Surgical Quality Improvement Program registry. Risk-adjusted hospital-level variation in 30-day death, serious morbidity, reoperation, readmission, and a composite of death or serious morbidity (DSM) were evaluated using hierarchical models. National Cancer Institute (NCI)-designated cancer center (NCI-CC) status was also explored. RESULTS: A total of 6203 operations across 589 hospitals were included, of which 56 were at NCI-CCs. Unadjusted rates of death, serious morbidity, reoperation, readmission, and DSM were 1.4%, 12.9%, 3.6%, 8.6%, and 13.4%, respectively. The coefficients of variation for hospital-level performance were 4.7%, 2.1%, 4.6%, 14.4%, and 1.0% for DSM, death, serious morbidity, unplanned reoperation, and unplanned readmissions, respectively. When compared with other hospitals, NCI-CCs had better risk-adjusted 30-day mortality (median odds ratio 0.984 versus 0.998, p < 0.001), but not for the other outcomes studied. CONCLUSIONS: Hospital-level variation was modestly detected using the usual measures of perioperative outcomes. Given the increasing interest in cytoreductive surgery, we demonstrate a clear opportunity to not only improve the quality of our care but to also better improve the way quality is measured for these patients.

Association of preoperative biliary drainage technique with postoperative outcomes among patients with resectable hepatobiliary malignancy.

BACKGROUND: Endoscopic biliary stenting (EBS) and percutaneous transhepatic biliary drainage (PTBD) are two techniques used for preoperative biliary drainage prior to hepatobiliary resection. The objectives of this study were to determine predictors of the drainage technique selection and to evaluate the association between drainage technique and postoperative outcomes. METHODS: Using ACS NSQIP data (2014-2017), patients who underwent preoperative biliary drainage prior to hepatobiliary resection for malignancy were identified. Separate multivariable-adjusted, propensity score (PS) adjusted, and PS matched logistic regression models were constructed to evaluate the association between drainage technique and postoperative outcomes. RESULTS: Of 527 patients identified, 431 (81.8%) received EBS and 96 (18.2%) received PTBD. Patients who underwent PTBD had more preoperative co-morbidities, including higher ASA class, recent weight loss, and hypoalbuminemia (all p < 0.05). After multivariable adjustment, PTBD was significantly associated with 30-day DSM (OR 1.92, 95% CI 1.24-2.97, p = 0.004), overall SSI (OR 1.74, 95% CI 1.10-2.76, p = 0.019), and superficial SSI (OR 2.08, 95% CI 1.20-3.60, p = 0.010). These findings remained significant for both PS-adjusted and PS-matched models. CONCLUSION: Patients undergoing hepatobiliary resection selected for PTBD had significantly more preoperative co-morbidities and nutritional deficits. Compared to EBS, PTBD was associated with significantly higher odds of postoperative morbidity and mortality.
