Pediatric Tele-Critical Care: Initial Experience with a Continuous Surveillance Model Aiming to Prevent Cardiac Arrest in Children with Critical Heart Disease.

Introduction: Despite advances in treatment of children with critical heart disease, cardiac arrest (CA) remains a common occurrence. We provided virtual support to bedside teams (BTs) from a tele-critical care (TCC) unit in a pediatric cardiac intensive care unit (CICU) and focused on early detection of concerning trends (CT) and avoidance of CA. Virtual surveillance workflows included a review of remote monitoring, video feed from patient room cameras, medical records, and artificial intelligence tools. We present our initial experience with a focus on critical communications (CCs) to BTs. Methods: A retrospective, descriptive review of TCC activities was conducted from January 2019 to December 2022, involving electronic databases and electronic medical records of patients in the CICU, including related CCs to BTs, responses from BTs, and related CA. Results: We conducted 18,171 TCC activities, including 2,678 non-CCs and 248 CCs. Over time, there was a significant increase in the proportion of CCs related with CT (p = 0.002), respiratory concerns (<0.001), and abnormalities in cardiac rhythm (p = 0.04). Among a sample of 244 CCs, subsequent interventions by BTs resulted in adjustment of medical treatment (127), respiratory support (68), surgery or intervention (19), cardiac rhythm control (17), imaging study (14), early resuscitation (9), and others (10). Conclusions: CCs from a TCC unit in a pediatric CICU changed over time with an increased focus on CT and resulted in early interventions, potentially contributing to avoiding CA. This model of care in pediatric cardiac critical care has the potential to improve patient safety.

Long-Term Outcomes after Spleen-Preserving Distal Pancreatectomy for Pancreatic Neuroendocrine Tumors: Results from the US Neuroendocrine Study Group.

BACKGROUND: The adoption of spleen-preserving distal pancreatectomy (SPDP) for malignant disease such as pancreatic neuroendocrine tumors (pNETs) has been controversial. The objective of the current study was to assess the impact of SPDP on outcomes of patients with pNETs. METHODS: Patients undergoing a distal pancreatectomy for pNET between 2002 and 2016 were identified in the US Neuroendocrine Tumor Study Group database. Propensity score matching (PSM) was used to compare short- and long-term outcomes of patients undergoing SPDP versus distal pancreatectomy with splenectomy (DPS). RESULTS: Among 621 patients, 103 patients (16.6%) underwent an SPDP. Patients who underwent SPDP were more likely to have lower BMI (median, 27.5 [IQR 24.0-31.2] vs. 28.7 [IQR 25.7-33.6]; p = 0.005) and have undergone minimally invasive surgery (n = 56, 54.4% vs. n = 185, 35.7%; p < 0.001). After PSM, while the median total number of lymph nodes examined among patients who underwent an SPDP was lower compared with DPS (3 [IQR 1-8] vs. 9 [5-13]; p < 0.001), 5-year overall survival (OS) and recurrence-free survival (RFS) were comparable (OS: 96.8 vs. 92.0%, log-rank p = 0.21, RFS: 91.1 vs. 84.7%, log-rank p = 0.93). In addition, patients undergoing SPDP had less intraoperative blood loss (median, 100 mL [IQR 10-250] vs. 150 mL [IQR 100-400]; p = 0.001), lower incidence of serious complications (n = 13, 12.8% vs. n = 28, 27.5%; p = 0.014), and shorter length of stay (median: 5 days [IQR 4-7] vs. 6 days [IQR 5-13]; p = 0.049) compared with patients undergoing DPS. CONCLUSION: SPDP for pNET was associated with acceptable perioperative and long-term outcomes that were comparable to DPS. SPDP should be considered for patients with pNET.

Assessment of Magnet status and Textbook Outcomes among medicare beneficiaries undergoing hepato-pancreatic surgery for cancer.

BACKGROUND: The relationship between hospital Magnet status recognition and postoperative outcomes following complex cancer surgery remains ill-defined. We sought to characterize Textbook Outcome (TO) rates among patients undergoing (HP) surgery for cancer in Magnet versus non-Magnet centers. METHODS: Medicare beneficiaries undergoing HP surgery between 2015 and 2017 were identified. The association of postoperative TO (no complications/extended length-of-stay/90-day mortality/90-day readmission) with Magnet designation was examined after adjusting for competing risk factors. RESULTS: Among 10,997 patients, 21.3% (n = 2337) patients underwent surgery at Magnet hospitals (non-Magnet centers: 78.7%, n = 8660). On multivariable analysis, patients undergoing HP surgery had comparable odds of achieving a TO at Magnet versus non-Magnet hospitals (hepatectomy: odds ratio [OR]: 1.05, 95% confidence interval [CI]: 0.94-1.17; pancreatectomy-OR: 0.88, 95% CI: 0.74-1.06). Patients treated at hospitals with a high nurse-to-bed ratio had higher odds of achieving a TO irrespective of whether they received surgery at Magnet (high vs. low nurse-to-bed ratio; OR: 1.38; 95% CI: 1.01-1.89) or non-Magnet centers (OR: 1.26; 95% CI: 1.10-1.45). Similarly, hospital HP volume was strongly associated with higher odds of TO following HP surgery in both Magnet (Leapfrog compliant vs. noncompliant; OR: 1.24, 95% CI: 1.06-1.44) and non-Magnet centers (OR: 1.18; 95% CI: 1.11-1.26). CONCLUSION: Hospital Magnet designation was not an independent factor of superior outcomes after HP surgery. Rather, hospital-level factors such as nurse-to-bed ratio and HP procedural volume drove outcomes.

Overall Tumor Burden Dictates Outcomes for Patients Undergoing Resection of Multinodular Hepatocellular Carcinoma Beyond the Milan Criteria.

OBJECTIVE: The objective of the current study was to define surgical outcomes after resection of multinodular hepatocellular carcinoma (HCC) beyond the Milan criteria, and develop a prediction tool to identify which patients likely benefit the most from resection. BACKGROUND: Liver resection for multinodular HCC, especially beyond the Milan criteria, remains controversial. Rigorous selection of the best candidates for resection is essential to achieve optimal outcomes after liver resection of advanced tumors. METHODS: Patients who underwent resection for HCC between 2000 and 2017 were identified from an international multi-institutional database. Patients were categorized according to Milan criteria status. Pre- and postoperative overall survival (OS) prediction models that included HCC tumor burden score (TBS) among patients with multinodular HCC beyond Milan criteria were developed and validated. RESULTS: Among 1037 patients who underwent resection for HCC, 164 (15.8%) had multinodular HCC beyond the Milan criteria. Among patients with multinodular HCC, 25 (15.2%) patients experienced a serious complication and 90-day mortality was 3.7% (n = 6). Five-year OS after resection of multinodular HCC beyond Milan criteria was 52.8%. A preoperative TBS-based model (5-year OS: low-risk, 73.7% vs intermediate-risk, 45.1% vs high-risk, 13.1%), and postoperative TBS-based model (5-year OS: low-risk, 80.1% vs intermediate-risk, 37.2% vs high-risk, not reached) categorized patients into distinct prognostic groups relative to long-term prognosis (both P < 0.001). Pre- and postoperative models could accurately stratify OS in an external validation cohort (5-year OS; low vs medium vs high risk; pre: 66.3% vs 25.2% vs not reached, P = 0.012; post: 61.4% vs 42.5% vs not reached, P = 0.045) Predictive accuracy of the pre- and postoperative models was good in the training (c-index; pre: 0.68; post: 0.71), internal validation (n = 2000 resamples) (c-index, pre: 0.70; post: 0.72) and external validation (c-index, pre: 0.67; post 0.68) datasets. TBS alone could stratify patients relative to 5-year OS after resection of multinodular HCC beyond Milan criteria (c-index: 0.65; 5-year OS; low TBS: 70.2% vs medium TBS: 54.7% vs high TBS: 16.7%; P < 0.001). The vast majority of patients with low and intermediate TBS were deemed low or medium risk based on both the preoperative (98.4%) and postoperative risk scores (95.3%). CONCLUSION: Prognosis of patients with multinodular HCC was largely dependent on overall tumor burden. Liver resection should be considered among patients with multinodular HCC beyond the Milan criteria who have a low- or intermediate-TBS.

Is Patient Satisfaction Dictated by Quality of Care Among Patients Undergoing Complex Surgical Procedures for a Malignant Indication?

BACKGROUND: The current study aimed to define the relationship between patient satisfaction, hospital-level factors, and clinical outcomes among patients undergoing major surgery for cancer. METHODS: The Medicare Inpatient Standard Analytic Files were used to identify patients undergoing lung, esophageal, colorectal, hepatic, or pancreatic surgery between 2016 and 2017, and Hospital Consumer Assessment of Healthcare Providers and Systems survey data were used to assess performance in terms of patient satisfaction. RESULTS: Among 60,446 patients, half were female (n = 31,244, 52%) with a median age of 73 years (interquartile range [IQR] 69-78 years). Patients who underwent surgery for esophageal resection (odds ratio [OR] 2.44; 95% confidence interval [CI] 1.10-5.40) and were Caucasian (OR 2.43; 95% CI 2.11-2.81) had optimal patient satisfaction. Hospital level factors such as urban location (OR 3.69; 95% CI 3.16-4.29), 200 + beds (OR 3.58; 95% CI 3.09-4.13), greater inpatient surgical volume (OR 3.03; 95% CI 2.82-3.25), higher nurse-to-bed ratio (OR 4.57; 95% CI 4.25-4.92), non-profit hospital status (OR 1.14; 95% CI 1.01-1.29), and non-teaching hospital status (OR 1.52; 95% CI 1.39-1.65) were related to optimal patient satisfaction. In adjusted analysis, patients undergoing surgery at hospitals reporting poor or average patient satisfaction had 22% higher odds of 90-day mortality than patients undergoing surgery at optimal-satisfaction hospitals (OR 1.22; 95% CI 1.09-1.36). In addition, hospitals with the highest patient satisfaction scores also had the highest proportion of surgical cases that achieved the composite textbook outcome (TO) quality metric (OR 1.12; 95% CI 1.05-1.20). CONCLUSION: Higher patient satisfaction was strongly associated with hospital structural measures such as bed number, urban location, nurse-to-bed ratio, and "optimal" TO after cancer surgery. These data highlight how high quality of care can directly lead to improved patient satisfaction among surgical patients with cancer.

Dedicated Cancer Centers are More Likely to Achieve a Textbook Outcome Following Hepatopancreatic Surgery.

INTRODUCTION: The aim of the current study is to assess rates of textbook outcome (TO) among Medicare beneficiaries undergoing hepatopancreatic (HP) surgery for cancer at dedicated cancer centers (DCCs) and National Cancer Institute affiliated cancer centers (NCI-CCs) versus non-DCC non-NCI hospitals. PATIENTS AND METHODS: Medicare Inpatient Standard Analytic Files were utilized to identify patients undergoing HP surgery between 2013 and 2017. TO was defined as no postoperative surgical complications, no 90-day mortality, no prolonged length of hospital stay, and no 90-day readmission after discharge. RESULTS: Among 21,234 Medicare patients, 8.2% patients underwent surgery at DCCs whereas 32.1% underwent surgery at NCI-CCs and 59.7% underwent an operation at neither DCCs nor NCI-CCs. Although DCCs more often cared for patients with severe comorbidities [Charlson score > 5: DCCs, 1195 (68.9%), NCI-CCs, 3687 (54.1%), others, 3970 (31.3%); p < 0.001], DCCs achieved higher rates of TO compared with NCI-CCs and other US hospitals. Interestingly, DCCs were more likely to perform surgery with a minimally invasive approach versus NCI-CCs and other US hospitals (17.0%, n = 295, vs. 12.6%, n = 856 vs. 11.9%, n = 1504, p < 0.001). On multivariable analysis, patients undergoing liver surgery at DCCs had 31% and 36% higher odds of achieving TO compared with NCI-CCs and other US hospitals, respectively. Medicare expenditure was substantially lower for patients achieving TO at DCCs compared with patients who achieved a TO at NCI-CCs. CONCLUSIONS: Even though DCCs more frequently took care of patients with high comorbidity burden, the likelihood of achieving TO for HP surgery at DCCs was higher compared with NCI-CCs and other US hospitals. The data suggest that DCCs provide higher-value surgical care for patients with HP malignancies.

CMS Hospital Compare System of Star Ratings and Surgical Outcomes Among Patients Undergoing Surgery for Cancer: Do the Ratings Matter?

BACKGROUND: The Centers for Medicare and Medicaid Services (CMS) Hospital Compare star rating system has been proposed as a means to assess hospital quality performance. The current study aimed to investigate outcomes and payments among patients undergoing surgery for colorectal, lung, esophageal, pancreatic, and liver cancer across hospital star rating groups. METHODS: The Medicare Standard Analytic Files (SAF) from 2013 to 2015 were used to derive the analytic cohort. The association of star ratings to perioperative outcomes and expenditures was examined. RESULTS: Among 119,854 patients, the majority underwent surgery at a 3-star (n = 34,901, 29.1%) or 4-star (n = 30,492, 25.4%) hospital. Only 12.2% (n = 14,732) were treated at a 5-star hospital. Across all procedures examined, patients who underwent surgery at a 1-star hospital had greater odds of death within 90 days than patients who had surgery at a 5-star hospital (colorectal, 1.41 [95% confidence interval {CI}, 1.25-1.60]; lung, 1.97 [95% CI 1.56-2.48]; esophagectomy, 1.83 [95% CI 0.81-4.16]; pancreatectomy, 1.70 [95% CI 1.20-2.41]; hepatectomy, 1.63 [95% CI 0.96-2.77]). A similar trend was noted for failure to rescue (FTR), with the greatest odds of FTR associated with 1-star hospitals. The median expenditure associated with an abdominal operation was $1661 more at a 1-star hospital than at a 5-star hospital (1-star: $17,399 vs 5-star: $15,738). A similar trend was noted for thoracic operations. CONCLUSION: The risk of FTR, 90-day mortality, and increased hospital expenditure were all higher at a 1-star hospital. Further research is needed to investigate barriers to care at 5-star-rated hospitals and to target specific interventions to improve outcomes at 1-star hospitals.

Recurrence Patterns and Outcomes after Resection of Hepatocellular Carcinoma within and beyond the Barcelona Clinic Liver Cancer Criteria.

BACKGROUND: Several investigators have advocated for extending the Barcelona Clinic Liver Cancer (BCLC) resection criteria to select patients with BCLC-B and even BCLC-C hepatocellular carcinoma (HCC). The objective of the current study was to define the outcomes and recurrence patterns after resection within and beyond the current resection criteria. PATIENTS AND METHODS: Patients who underwent resection for HCC within (i.e., BCLC 0/A) and beyond (i.e. BCLC B/C) the current resection criteria between 2005 and 2017 were identified from an international multi-institutional database. Overall survival (OS), disease-free survival (DFS), as well as patterns of recurrence of patients undergoing HCC resection within and beyond the BCLC guidelines were examined. RESULTS: Among 756 patients, 602 (79.6%) patients were BCLC 0/A and 154 (20.4%) were BCLC B/C. Recurrences were mostly intrahepatic (within BCLC: 74.3% versus beyond BCLC: 70.8%, p = 0.80), with BCLC B/C patients more often having multiple tumors at relapse (69.6% versus 49.4%, p = 0.001) and higher rates of early (< 2 years) recurrence (88.0% versus 75.5%, p = 0.011). During the first postoperative year, annual recurrence was 38.3% and 21.3% among BCLC B/C and BCLC 0/A patients, respectively; 5-year OS among BCLC 0/A and BCLC B/C patients was 76.9% versus 51.6% (p = 0.003). On multivariable analysis, only a-fetoprotein (AFP) > 400 ng/mL (HR = 1.84, 95% CI 1.07-3.15) and R1 resection (HR = 2.36, 95% CI 1.32-4.23) were associated with higher risk of recurrence among BCLC B/C patients. CONCLUSIONS: Surgery can provide acceptable outcomes among select patients with BCLC B/C HCC. The data emphasize the need to further refine the BCLC treatment algorithm as well as highlight the need for surveillance protocols with a particular focus on the liver, especially for patients undergoing resection outside the BCLC criteria.

Assessing Textbook Outcomes Following Liver Surgery for Primary Liver Cancer Over a 12-Year Time Period at Major Hepatobiliary Centers.

INTRODUCTION: The objective of the current study was to comprehensively assess the change of practice in hepatobiliary surgery by determining the rates and the trends of textbook outcomes (TO) among patients undergoing surgery for primary liver cancer over time. METHODS: Patients undergoing curative-intent resection for primary liver malignancies, including hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) between 2005 and 2017 were analyzed using a large, international multi-institutional dataset. Rates of TO were assessed over time. Factors associated with achieving a TO and the impact of TO on long-term survival were examined. RESULTS: Among 1829 patients, 944 (51.6%) and 885 (48.4%) individuals underwent curative-intent resection for HCC and ICC, respectively. Over time, patients were older, more frequently had ASA class > 2, albumin-bilirubin grade 2/3, major vascular invasion and more frequently underwent major liver resection (all p < 0.05). Overall, a total of 1126 (62.0%) patients achieved a TO. No increasing trends in TO rates were noted over the years (ptrend = 0.90). In addition, there was no increasing trend in the TO rates among patients undergoing either major (ptrend = 0.39) or minor liver resection (ptrend = 0.63) over the study period. Achieving a TO was independently associated with 26% and 37% decreased hazards of death among ICC (HR 0.74, 95%CI 0.56-0.97) and HCC patients (HR 0.63, 95%CI 0.46-0.85), respectively. CONCLUSION: Approximately 6 in 10 patients undergoing surgery for primary liver tumors achieved a TO. While TO rates did not increase over time, TO was associated with better long-term outcomes following liver resection for both HCC and ICC.

The Impact of Preoperative CA19-9 and CEA on Outcomes of Patients with Intrahepatic Cholangiocarcinoma.

BACKGROUND: The objective of the current study was to assess the impact of serum CA19-9 and CEA and their combination on survival among patients undergoing surgery for intrahepatic cholangiocarcinoma (ICC). METHODS: Patients who underwent curative-intent resection of ICC between 1990 and 2016 were identified using a multi-institutional database. Patients were categorized into four groups based on combinations of serum CA19-9 and CEA (low vs. high). Factors associated with 1-year mortality after hepatectomy were examined. RESULTS: Among 588 patients, 5-year OS was considerably better among patients with low CA19-9/low CEA (54.5%) compared with low CA19-9/high CEA (14.6%), high CA19-9/low CEA (10.0%), or high CA19-9/high CEA (0%) (P < 0.001). No difference in 1-year OS existed between patients who had either high CA19-9 (high CA19-9/low CEA: 70.4%) or high CEA levels (low CA19-9/high CEA: 72.5%) (P = 0.92). Although patients with the most favorable tumor marker profile (low CA19-9/low CEA) had the best 1-year survival (87.9%), 15.1% (n = 39) still died within a year of surgery. Among patients with low CA19-9/low CEA, a high neutrophil-to-lymphocyte ratio (NLR) (odds ratio 1.09; 95% confidence interval 1.03-1.64) and large size tumor (odds ratio 3.34; 95% confidence interval 1.40-8.10) were associated with 1-year mortality (P < 0.05). CONCLUSIONS: Patients with either a high CA19-9 and/or high CEA had poor 1-year survival. High NLR and large tumor size were associated with a greater risk of 1-year mortality among patients with favorable tumor marker profile.

Trends in the Number of Lymph Nodes Evaluated Among Patients with Pancreatic Neuroendocrine Tumors in the United States: A Multi-Institutional and National Database Analysis.

BACKGROUND: The role of routine lymphadenectomy in the surgical treatment of pancreatic neuroendocrine tumors (pNET) remains poorly defined. The objective of the current study was to investigate trends in the number of lymph nodes (LN) evaluated for pNET treatment at a nationwide level. METHODS: Patients undergoing surgery for pNET between 2000 and 2016 were identified in the U.S. Neuroendocrine Tumor Study Group (US-NETSG) database as well as the Surveillance, Epidemiology, and End Results (SEER) database. The number of LNs examined was evaluated over time. RESULTS: The median number of evaluated LNs increased roughly fourfold over the study period (US-NETSG, 2000: 3 LNs vs. 2016: 13 LNs; SEER, 2000: 3 LNs vs. 2016: 11 LNs, both p < 0.001). While no difference in 5-year OS and RFS was noted among patients who had 1-3 lymph node metastases (LNM) vs. ≥ 4 LNM between 2000-2007 (OS 73.5% vs. 69.9%, p = 0.12; RFS: 64.9% vs. 40.1%, p = 0.39), patients who underwent resection and LN evaluation during the period 2008-2016 had an incrementally worse survival if the patient had node negative disease, 1-3 LNM and ≥ 4 LNM (OS 86.8% vs. 82.7% vs. 74.9%, p < 0.001; RFS: 86.3% vs. 64.7% vs. 50.4%, p < 0.001). On multivariable analysis, a more recent year of diagnosis, pancreatic head tumor location, and tumor size > 2 cm were associated with 12 or more LNs evaluated in both US-NETSG and SEER databases. CONCLUSION: The number of LNs examined nearly quadrupled over the last decade. The increased number of LNs examined suggested a growing adoption of the AJCC staging manual recommendations regarding LN evaluation in the treatment of pNET.

A Machine-Based Approach to Preoperatively Identify Patients with the Most and Least Benefit Associated with Resection for Intrahepatic Cholangiocarcinoma: An International Multi-institutional Analysis of 1146 Patients.

BACKGROUND: Accurate risk stratification and patient selection is necessary to identify patients who will benefit the most from surgery or be better treated with other non-surgical treatment strategies. We sought to identify which patients in the preoperative setting would likely derive the most or least benefit from resection of intrahepatic cholangiocarcinoma (ICC). METHODS: Patients who underwent curative-intent resection for ICC between 1990 and 2017 were identified from an international multi-institutional database. A machine-based classification and regression tree (CART) was used to generate homogeneous groups of patients relative to overall survival (OS) based on preoperative factors. RESULTS: Among 1146 patients, CART analysis revealed tumor number and size, albumin-bilirubin (ALBI) grade and preoperative lymph node (LN) status as the strongest prognostic factors associated with OS among patients undergoing resection for ICC. In turn, four groups of patients with distinct outcomes were generated through machine learning: Group 1 (n = 228): single ICC, size ≤ 5 cm, ALBI grade I, negative preoperative LN status; Group 2 (n = 708): (1) single tumor > 5 cm, (2) single tumor ≤ 5 cm, ALBI grade 2/3, and (3) single tumor ≤ 5 cm, ALBI grade 1, metastatic/suspicious LNs; Group 3 (n = 150): 2-3 tumors; Group 4 (n = 60): ≥ 4 tumors. 5-year OS among Group 1, 2, 3, and 4 patients was 60.5%, 35.8%, 27.5%, and 3.8%, respectively (p < 0.001). Similarly, 5-year disease-free survival (DFS) among Group 1, 2, 3, and 4 patients was 47%, 27.2%, 6.8%, and 0%, respectively (p < 0.001). CONCLUSIONS: The machine-based CART model identified distinct prognostic groups of patients with distinct outcomes based on preoperative factors. Survival decision trees may be useful as guides in preoperative patient selection and risk stratification.

Utilizing Machine Learning for Pre- and Postoperative Assessment of Patients Undergoing Resection for BCLC-0, A and B Hepatocellular Carcinoma: Implications for Resection Beyond the BCLC Guidelines.

BACKGROUND: There is an ongoing debate about expanding the resection criteria for hepatocellular carcinoma (HCC) beyond the Barcelona Clinic Liver Cancer (BCLC) guidelines. We sought to determine the factors that held the most prognostic weight in the pre- and postoperative setting for each BCLC stage by applying a machine learning method. METHODS: Patients who underwent resection for BCLC-0, A and B HCC between 2000 and 2017 were identified from an international multi-institutional database. A Classification and Regression Tree (CART) model was used to generate homogeneous groups of patients relative to overall survival (OS) based on pre- and postoperative factors. RESULTS: Among 976 patients, 63 (6.5%) had BCLC-0, 745 (76.3%) had BCLC-A, and 168 (17.2%) had BCLC-B HCC. Five-year OS among BCLC-0/A and BCLC-B patients was 64.2% versus 50.2%, respectively (p = 0.011). The preoperative CART model selected α-fetoprotein (AFP) and Charlson comorbidity score (CCS) as the first and second most important preoperative factors of OS among BCLC-0/A patients, whereas radiologic tumor burden score (TBS) was the best predictor of OS among BCLC-B patients. The postoperative CART model revealed lymphovascular invasion as the best postoperative predictor of OS among BCLC-0/A patients, whereas TBS remained the best predictor of long-term outcomes among BCLC-B patients in the postoperative setting. On multivariable analysis, pathologic TBS independently predicted worse OS among BCLC-0/A (hazard ratio [HR] 1.04, 95% confidence interval [CI] 1.02-1.07) and BCLC-B patients (HR 1.13, 95% CI 1.06-1.19) undergoing resection. CONCLUSION: Prognostic stratification of patients undergoing resection for HCC within and beyond the BCLC resection criteria should include assessment of AFP and comorbidities for BCLC-0/A patients, as well as tumor burden for BCLC-B patients.

Multidisciplinary approach achieves limb salvage without revascularization in patients with mild to moderate ischemia and tissue loss.

OBJECTIVE: The Society for Vascular Surgery Wound, Ischemia, and foot Infection (WIfI) classification system has been validated to predict wound healing and limb salvage of patients with peripheral artery disease (PAD). Our goal was to evaluate the association between WIfI stage and wound healing, limb salvage, and survival in a select cohort of patients with PAD and tissue loss undergoing an attempt of wound healing without immediate revascularization (conservative approach) in a multidisciplinary wound program. METHODS: Veterans with PAD and tissue loss were prospectively enrolled in our Prevention of Amputation in Veterans Everywhere (PAVE) program. Limbs were stratified to a conservative, revascularization, primary amputation, and palliative limb care approach based on the patient's fitness, ambulatory status, perfusion evaluation, and validated pathway of care. Rates of wound healing, wound recurrence, limb salvage, and survival were retrospectively analyzed by WIfI clinical stages (stage 1-4) in the conservative group. Cox regression modeling was used to estimate clinical outcomes by WIfI stage. RESULTS: Between January 2006 and October 2017, there were 961 limbs prospectively enrolled in our PAVE program. A total of 233 limbs with 277 wounds were stratified to the conservative approach. WIfI staging distribution included 19.7% stage 1, 20.2% stage 2, 38.6% stage 3, and 21.5% stage 4. All ischemia scores were classified as 1 or 2. Advanced wound interventions and minor amputations were performed on 40 limbs (16.6%) and 57 limbs (23.7%), respectively. Average long-term follow-up was 41.4 ± 29.0 months. Complete wound healing without revascularization was achieved in 179 limbs (76.8%) during 4.4 ± 4.1 months. Thirty-four limbs (14%) underwent deferred revascularization because of a lack of complete wound healing. At long-term follow-up, wound recurrence per limb was 39%. Overall limb salvage at long-term follow-up was 89.3%. Stratified by WIfI stage, there was no statistically significant difference between groups for wound healing (P = .64), wound recurrence (P = .55), or limb salvage (P = .66) after adjustment for significant patient, limb, and wound characteristics. CONCLUSIONS: In select patients with mild to moderate ischemia and tissue loss, a stratified approach can achieve acceptable rates of wound healing and limb salvage, with limited need for deferred revascularization. WIfI clinical staging did not predict wound healing, limb salvage, or survival in this cohort.

Photodynamic therapy may provide a benefit over systemic chemotherapy among non-surgically managed patients with extrahepatic cholangiocarcinoma.

BACKGROUND: Systemic chemotherapy is the standard treatment for patients with unresectable extrahepatic cholangiocarcinoma (ECC), however, the survival benefit of chemotherapy is limited. Photodynamic therapy (PDT) has been associated with improved survival among patients with advanced ECC, yet utilization of PDT remains low. We sought to compare the outcomes of patients with unresectable ECC following treatment with PDT versus chemotherapy. METHODS: A review of the National Cancer Database was conducted to identify patients with ECC who were nonsurgically managed between 2004 and 2013. Overall survival (OS) of patients receiving PDT vs systemic chemotherapy was compared using propensity score matching. RESULTS: After propensity matching (PDT, n = 59; chemotherapy, n = 177), 5-year OS was 17.6% (95% confidence interval [CI], 9.0%-28.6%) among patients who underwent PDT vs 3.8% (95%CI, 0.4%-14.0%) among patients receiving chemotherapy (P < .001). On multivariable analysis PDT was associated with an OS benefit (hazard ratio, 0.72; 95%CI, 0.52-0.998; P = .048). Subset analysis of patients receiving PDT only (n = 45) and patients receiving chemotherapy demonstrated similar results. In subset analysis of patients undergoing PDT-only vs PDT-chemotherapy, OS was comparable. CONCLUSION: PDT was associated with a survival benefit compared with chemotherapy alone among patients with unresectable ECC.

Comparing textbook outcomes among patients undergoing surgery for cancer at U. S. News & World Report ranked hospitals.

BACKGROUND: The objective of the current study was to define and compare rates of textbook outcomes (TO) among patients undergoing colorectal, lung, esophagus, liver, and pancreatic surgery for cancer at U.S. News & World Report (USNWR) ranked hospitals. METHODS: Medicare Inpatient Standard Analytic Files 2013-2015 were utilized to examine the relationship of TO and USNWR hospital ratings following surgery for colorectal, lung, esophageal, pancreatic, and liver cancer. TO was defined as no postoperative surgical complications, no prolonged length of hospital stay, no readmission within 90 days after discharge, and no postoperative mortality within 90 days after surgery. RESULTS: Among the 35,352 Medicare patients included in the cohort, 16,820 (47.6%) underwent surgery at honor roll hospitals, whereas 18 532 (52.4%) underwent surgery at non-honor roll hospitals. The overall proportion of patients who achieved TO was 50.1%. In examining the clinical outcomes of patients who underwent surgery, there was no difference in the odds of achieving TO at honor roll vs non-honor roll hospitals (colorectal: odds ratio [OR], 0.87; 95% confidence interval [CI], 0.69-1.10; lung: OR, 1.07; 95% CI, 0.87-1.32; esophagus: OR, 1.44; 95% CI, 0.72-2.89; liver: OR, 1.27; 95% CI, 0.87-1.84; pancreas: OR, 1.04; 95% CI, 0.67-1.62). CONCLUSION AND RELEVANCE: Patients undergoing surgery for lung, esophageal, liver, pancreatic, and colorectal cancer had comparable rates of TO at honor roll vs non-honor roll hospitals. No linear association was observed between hospital position in the rank and postoperative outcomes such as TO indicating that patients should not overly focus on the exact position within USNWR ranked hospitals. These data highlight to patients and physicians that up to one-half of patients undergoing surgery for cancer should anticipate at least one adverse outcome.

Recurrence beyond the Milan criteria after curative-intent resection of hepatocellular carcinoma: A novel tumor-burden based prediction model.

BACKGROUND: Accurate prediction of recurrence patterns of hepatocellular carcinoma (HCC) may allow for prioritization of patients for resection or transplantation as well as guide post-resection surveillance strategies. METHODS: Patients who underwent curative-intent R0 resection for HCC between 2000 and 2017 were identified using a multi-institutional database. A prognostic model that incorporated HCC tumor burden score (TBS) to predict recurrence beyond the Milan criteria (MC) was developed and validated. RESULTS: Among 718 patients who underwent R0 resection for HCC, 185 (25.8%) recurred within and 110 (15.3%) beyond the MC. On multivariable analysis, AFP more than 400 ng/mL (hazard ratio [HR] = 2.26; 95% confidence interval [CI]: 1.27-4.02), lymphovascular invasion (HR = 2.00; 95% CI: 1.14-3.50), and TBS (HR = 1.08; 95% CI: 1.03-1.12) were associated with recurrence beyond the MC. A weighted TBS-based score was constructed: [0.074*TBS + 0.692*lymphovascular invasion (yes: 1, no: 0) + 0.816*AFP > 400 (yes:1, no:0)]. Patients with a low, medium, and high TBS-based risk score had a 5-year incidence of recurring beyond the MC of 16.2%, 28.6%, and 47.2%, respectively (P < .001). The predictive accuracy of the model was very good in the training (C-index: 0.761) and validation (C-index: 0.706) datasets and outperformed the previously reported clinical risk score (CRS; C-index: 0.680). CONCLUSION: A TBS-based model accurately predicted recurrence beyond MC after curative-intent resection of HCC and outperformed the CRS. Incorporating TBS allows for better risk stratification and identifies patients in need of closer surveillance.

Travel to a high volume hospital to undergo resection of gallbladder cancer: does it impact quality of care and long-term outcomes?

BACKGROUND: The relationship of volume and travel distance to patient outcomes after resection of gallbladder cancer (GBC) remains poorly defined. METHODS: The 2004-2015 National Cancer Database was used to identify GBC resection patients and examine the impact of travel distance, hospital volume and both on overall survival (OS) and quality of care indicators. RESULTS: Among 10,174 patients undergoing surgery for GBC, the majority of patients were Caucasian (N = 8,175, 80%) and had a Charlson-Deyo comorbidity score of 0 (N = 6,785, 67%). On unadjusted survival analysis increasing travel distance and hospital volume were associated with improved OS (both p < 0.001). After controlling for competing risk factors, the 4th quartile of hospital volume was associated with a decreased hazard of death (HR 0.831, 95% CI 0.751-0.920, p < 0.001). When both hospital volume and travel distance were included, the association with improved OS persisted only for hospital volume (4th quartile HR 0.835, 95% CI 0.753-0.925, p < 0.001), whereas there was no independent association of increasing travel distance with OS. CONCLUSIONS: Both increasing travel distance and hospital volume were associated with improved OS; however, adjusted models demonstrated that the impact of travel distance was mediated through hospital volume.

Skilled nursing facility (SNF) utilization and impact of SNF star-quality ratings on outcomes following hepatectomy among Medicare beneficiaries.

BACKGROUND: An increasing number of patients require admission to a skilled nursing facility (SNF) following surgery. However, the impact of SNF quality on post-operative outcomes is unknown. METHODS: The Medicare Standard Analytic Files and Nursing Home Compare Dataset were used to define SNF utilization and determine the influence of SNF star quality ratings on outcomes following hepatectomy. RESULTS: Among 7256 Medicare beneficiaries, 918 (12.7%) required. Compared to patients discharged home, individuals discharged to SNF were older (median age: 75 [IQR 71-80] vs. 71 [IQR 68-76] years), and had a higher incidence of complications such as pulmonary failure, pneumonia, and acute renal failure during index hospitalization (all p < 0.05). Patients sent to a SNF were more likely to be readmitted within 30-days (30.1% vs. 13.4%, p < 0.001). The incidence of new complications within 30- and 90-days of discharge was similar regardless of star quality ratings (all p > 0.05). On multivariable analysis, Charlson comorbidity score ≥3 was the factor most strongly associated with 30-day readmission (OR 1.32-15.29, p = 0.016). CONCLUSION: While post-discharge outcomes were similar across SNF quality ratings, roughly one in three Medicare patients discharged to a SNF were readmitted within 30-days.
