Association Between Utilization of Services and Perioperative Outcomes for Lung Cancer Resection.

INTRODUCTION: Lung cancer resection has largely focused on perioperative outcomes (eg, mortality) to benchmark performance. While variations in perioperative outcomes and in utilization of services (eg, ambulatory procedures, hospitalization) have been independently demonstrated, there has been limited evaluation of associations between these outcomes. We evaluated the association between perioperative outcomes and utilization of services to evaluate provider performance across a broader context of care. PATIENTS AND METHODS: This was a retrospective cohort study of patients undergoing lung cancer resection in 2017 to 2019. We utilized hierarchical logistic regression models to determine risk- and reliability-adjusted mortality and risk-adjusted utilization of services, at the hospital-level. We then evaluated utilization of services across quartiles of perioperative mortality. RESULTS: A total of 15,168 patients across 297 hospitals underwent lung cancer resection. Mean risk- and reliability-adjusted 90-day mortality varied between 1.58% (95% CI, 1.54%-1.62%) and 2.74% (95% CI, 2.59%-2.90%) across quartiles. Risk-adjusted utilization of all ambulatory procedures was highest in the best performing (lowest mortality) quartile at 37.7% (95% CI, 33.6%-41.8%). Additionally, risk-adjusted inpatient utilization prior to and after surgery was lowest in the best performing quartile at 15% (95% CI, 13.7%-16.3%) and 19.3% (95% CI, 17.5%-21.0%), respectively. CONCLUSIONS: Hospitals with the lowest perioperative mortality demonstrated trends towards using more outpatient resources prior to surgery, but fewer inpatient services surrounding lung cancer resection. This correlation highlights the importance of incorporating utilization of services in addition to other metrics to profile the efficiency and effectiveness of centers performing lung cancer resection across a broader spectrum of care.

Impact of stereotactic body radiation therapy volume on surgical patient selection, short-term survival, and long-term survival in early-stage non-small cell lung cancer.

OBJECTIVES: Stereotactic body radiation therapy (SBRT) is increasingly used to treat non-small cell lung cancer. The purpose of this study is to analyze relationships between facility SBRT utilization and surgical patient selection and survival after surgery. METHODS: Data on patients with TI/T2N0M0 lesions and treatment facility characteristics were abstracted from the National Cancer Database, 2008 to 2017. Facilities were stratified using an SBRT/surgery ratio previously associated with short-term survival benefit for patients treated surgically, and by a previously identified surgical volume threshold. Multiple regression analyses, Cox proportional-hazard regressions, and Kaplan-Meier log rank test were employed. RESULTS: In total, 182,610 patients were included. Proportion of high SBRT:surgery ratio (≥17%) facilities increased from 118 (11.5%) to 558 (48.4%) over the study period. Patients undergoing surgery at high-SBRT facilities had comparable comorbidity scores and tumor sizes to those at low-SBRT facilities, and nonclinically significant differences in age, race, and insurance status. Among low-volume surgical facilities, treatment at a high SBRT-using facility was associated with decreased 30-day mortality (1.8% vs 1.4%, P < .001) and 90-day mortality (3.3% vs 2.6%, P < .001). At high-volume surgical facilities, no difference was observed. At 5 years, a survival advantage was identified for patients undergoing resection at facilities with high surgical volumes (hazard ratio, 0.91; confidence interval, 0.90-0.93 P < .001) but not at high SBRT-utilizing facilities. CONCLUSIONS: Differences in short-term survival following resection at facilities with high-SBRT utilization may be attributable to low surgical volume facilities. Patients treated at high volume surgical facilities do not demonstrate differences in short-term or long-term survival based on facility SBRT utilization.

Hospital Utilization of Stereotactic Body Radiation Therapy and Rates of Surgical Refusal.

BACKGROUND: Increasingly, stereotactic body radiation therapy (SBRT) is used for patients unfit for or unwilling to undergo operation for early-stage non-small cell lung cancer. It remains unclear how SBRT utilization has influenced patient refusal of surgical resection. METHODS: A retrospective cohort analysis was completed using the National Cancer Database for patients with T1/T2 N0 M0 lesions from 2008 to 2017. Facilities were categorized into tertiles by SBRT/surgery ratio for each year of analysis. Propensity score matching was used to compare rates of surgical refusal and rates of postrefusal receipt of SBRT. Multivariable regression analysis was performed to evaluate effect size. RESULTS: The study included 129 901 patients; 63 048 were treated at low-tertile SBRT/surgery facilities, 41 674 at middle-tertile SBRT/surgery facilities, and 25 179 at high-tertile SBRT/surgery facilities. Patients refusing surgery at high SBRT/surgery facilities had fewer comorbid conditions and smaller tumors. Rates of SBRT after surgical refusal differed (low SBRT/surgery facilities, 17.2%; high SBRT/surgery facilities, 55.9%; P < .001). In a matched cohort of 76 636, surgical refusal differed (low SBRT/surgery facilities, 4.2%; high SBRT/surgery facilities, 6.0%; P < .001). On multivariable regression, treatment at a top-tertile SBRT/surgery facility was the largest risk factor for surgical refusal (odds ratio, 3.82 [3.53-4.13]; P < .001) and was most strongly associated with postrefusal receipt of SBRT (odds ratio, 6.11 [5.09-7.34]; P < .001). CONCLUSIONS: Patients treated at high SBRT-using facilities are more likely to refuse surgical resection and more likely to receive radiation therapy after surgical refusal. Further analysis is needed to better understand patient refusal of surgery in the setting of early-stage non-small cell lung cancer.

National trends in pectus excavatum repair: patient age, facility volume, and outcomes.

Background: There is limited data on the adult repair of pectus excavatum (PE). Existing literature is largely limited to single institution experiences and suggests that adults undergoing modified Nuss repair may have worse outcomes than pediatric and adolescent patients. Using a representative national database, this analysis is the first to describe trends in demographics, outcomes, charges, and facility volume for adults undergoing modified Nuss procedure. Methods: Because of a coding change associated with ICD-10, a retrospective cohort analysis using the National Inpatient Sample (NIS) for patients 12 or older undergoing modified Nuss repair between 2016-2018 was possible. Pearson's χ2 and Student's t-tests were utilized to compare patient, clinical, and hospital characteristics. Complications were sub-classified into major and minor categories. Facilities performing greater than the mean number of operations were categorized as high-volume. Results: Of 360 patients, 79.2% were male. There was near gender parity for patients over 30 undergoing repair (55.2% male, 44.8% female). In all age cohorts, patients were predominantly Caucasian. Rates of any postoperative complication differed by age (12-17 years: 30.6%; 18-29 years: 45.2%; 30+ years: 62.1%; P<0.01); older patients had higher rates of all but two subclasses of complication. Age over 30 was associated with higher charges (12-17 years: $57,312; 18-29 years: $57,001; 30+ years: $67,014; P<0.01). High-volume centers operate on older patients, had shorter lengths of stay, and comparable charges to low-volume centers. Conclusions: Women comprise nearly half of patients undergoing modified Nuss repair after 30 years of age. There are significant differences in complication rates and charges when comparing patients by age. Patients undergoing repair at high-volume facilities benefitted from shorter lengths of stay.

Crisis management checklist: lessons learned from the SARS-CoV-2 pandemic.

"Everyone has a plan until they get punched in the mouth." Never has this quote, uttered in response to a challenger's reported plan to take the title away from heavyweight champion Mike Tyson, rang truer than in the past 20 months as the global population wrestles with the fallout on the SARS-CoV-2 pandemic. While countless lives were disrupted both directly and indirectly during this time, members of the medical community bore the brunt of this fallout in their personal lives while being asked to perform above capacity in their professional lives simultaneously. Compounding this experience was the fact that injuries, illness, and death from other causes did not halt leaving many in the medical community, and community at large, to face personal tragedies in addition to the pandemic. Our goal is to create a series of discussions using the perspective of our surgical department that faced not only the fallout of the pandemic, but also the unexpected death of an influential mentor/physician and close family member to the department. Unfortunately, this pandemic is not the only time tragedy has struck a surgical department. For example, Louisiana State University and Hurricane Katrina in 2007, and a plane crash killing members of the University of Michigan transplant team. However, the pandemic is certainly the most globally widespread, relevant and recent. We leverage crisis-management strategies from other fields, responses from an internal survey, and thoughts from our surgical team on what worked during these crises, what did not, and how we can begin to create a strategic response for those unexpected moments where you get "punched in the mouth."

68Ga-Prostate-Specific Membrane Antigen Uptake as a Surrogate Biomarker of Neovascularity in Hepatocellular Carcinoma.

68Ga-prostate-specific membrane antigen (68Ga-PSMA) is expressed in the endothelium of tumor-associated neovasculature of various solid malignancies possibly due to tumor-associated angiogenic factors and endothelial cell sprouting. We report a case of a 45-year-old man with known colorectal cancer, cirrhosis, and hepatitis C. Contrast-enhanced computed tomography (CT) showed a hypervascular lesion in the liver, and 18F-fluorodeoxyglucose positron emission tomography (PET) did not show any suspicious hepatic uptake. 68Ga-PSMA PET-CT showed predominantly heterogeneous perilesional uptake in a configuration similar to the arterial enhancement pattern on the diagnostic CT. 68Ga-PSMA uptake in hepatocellular carcinoma appears to be primarily neoangiogenesis driven, and its morphological and functional characterization can subsequently influence the selection of anti-neoangiogenic chemotherapy agents as well as guiding radionuclide ligand therapy.

A Very Unusual Pattern of Intraperitoneal and Extraperitoneal Heterotropic Splenic Tissue-Mimicking Metastases Identified on 68Ga-DOTA-NOC Positron Emission Tomography/Computed Tomography and 99mTc Heat-denatured Erythrocyte Study.

The dissemination and autotransplantation of viable splenic tissue in different anatomic compartments of the body can present a diagnostic dilemma, especially when metastatic disease is suspected. We report a case of a 30-year-old male with well-differentiated gastric neuroendocrine tumor (Grade II) treated with surgery. Follow-up 68Ga-DOTA-NOC demonstrated a suspicious peritoneal soft-tissue nodule in the right paracolic gutter with increased tracer uptake. In view of splenectomy 10 years ago, the patient underwent 99mTc heat-denatured erythrocyte study which showed a very unusual pattern of multiple tracer-avid foci of splenic tissue in both intraperitoneal and extraperitoneal distributions. The integration of the patient's history and complementary nuclear imaging results led to the correct diagnosis of splenosis.

Pulmonary contusions in the elderly after blunt trauma: incidence and outcomes.

BACKGROUND: In the general population with blunt chest trauma, pulmonary contusions (PCs) are commonly identified. However, there is limited research in the elderly. We sought to evaluate the incidence and outcomes of PCs in elderly blunt trauma admissions. METHODS: We retrospectively reviewed the trauma registry at a level I trauma center for all blunt thoracic trauma patients aged ≥65 y, who were admitted between 2007 and 2015. The medical records of PC patients were reviewed. RESULTS: There were 956 admissions with blunt thoracic trauma; of which 778 had no pulmonary contusion (NO) and 178 had PC. The major mechanisms of injury were falls (58.7% NO, 39.3% PC, P <0.001) and motor vehicle crash/motor cycle crash (35.6% NO, 51.7% PC, P <0.001). Rib fractures were present in 79.8% of PC and 73.8% of NO patients, P = 0.1. PC patients more often had serious (AIS ≥3) head/neck (30.3% versus 20.6%, P <0.001), abdomen (12.4% versus 6.6%, P <0.001), and extremity injuries (20.8% versus 11.4%, P <0.001). Complication (46.1% PC versus 26.6% NO, P <0.001) and mortality (14.0% PC versus 6.2% NO, P = 0.0003) rates were higher in PC patients. On multivariate logistic regression analyses, PC presence was significantly associated with mechanical ventilation (odds ratio 2.5), intensive care unit admission (odds ratio 2.3), and mortality (odds ratio 1.9). CONCLUSIONS: Over 18.6% of elderly blunt thoracic trauma patients sustained PC, despite an often low energy mechanism of injury. The presence of a PC should prompt investigation for other serious intrathoracic and extrathoracic injuries. PC presence is associated with substantial morbidity and mortality.

Routine contrast imaging after bariatric surgery and the effect on hospital length of stay.

BACKGROUND: Although multiple studies demonstrate that routine postoperative contrast studies have a low yield in diagnosing patients with early gastrointestinal (GI) leak after bariatric surgery, the practice pattern is unknown. Additionally, routine imaging may hinder procedural pathways that lead to accelerated postoperative discharge. OBJECTIVES: To report on the nationwide use of routine upper GI studies (UGI) and evaluate the effect on hospital resource utilization. SETTING: Nationwide analysis of accredited centers. METHODS: The Metabolic and Bariatric Surgery Accreditation Quality and Improvement Program public use file for 2015 was used to identify patients who underwent routine UGI after nonrevisional Roux-en-Y gastric bypass or sleeve gastrectomy. Multivariable logistic regression models were developed to identify risk factors for early hospital discharge. RESULTS: Bariatric surgery was performed on 130,686 patients. Routine UGI was performed in 30.9% of Roux-en-Y gastric bypass and 43% of sleeve gastrectomy patients (P<.0001). Patients undergoing routine UGI were less likely to be discharged by postoperative day 1 (odds ratio .7, 95%; confidence interval .69-0.72). There was no difference in postoperative leak rate between the routine UGI versus nonroutine UGI group (.7% versus .8%, P = .208). Among patients who developed a GI leak, there was no significant difference in the rate of reoperation, readmission, and reintervention between the 2 groups. The time interval between index operation and any further management for the leak was longer in the routine UGI group. CONCLUSIONS: Routine UGI evaluation after bariatric surgery remains a common practice in accredited centers. This practice is associated with prolonged hospital length of stay, with no effect on the diagnosis of leak rate.
