RESUMEN
INTRODUCTION: Lumbar laminotomy/diskectomy is a common procedure performed to address radiculopathy that persists despite conservative treatment. Understanding cost/reimbursement variability and its drivers has the potential to help optimize related healthcare delivery. The goal of this study was to assess variability and factors associated with reimbursement through 90 days after single-level lumbar laminotomy/diskectomy. METHODS: Lumbar laminotomies/diskectomies were isolated from the 2010 to 2021 PearlDiver M151 data set. Exclusion criteria included patients younger than 18 years; other concomitant spinal procedures; and indications of trauma, oncologic, or infectious diagnoses. Patient, surgical, and perioperative data were abstracted. These variables were examined using a multivariable linear regression model with Bonferroni correction to determine factors independently correlated with reimbursement. RESULTS: A total of 28,621 laminotomies/diskectomies were identified. The average ± standard deviation 90-day postoperative reimbursement was $9,453.83 ± 19,343.99 and, with a non-normal distribution, the median (inner quartile range) was $3,314 ($5,460). By multivariable linear regression, variables associated with greatest increase in 90-day postoperative reimbursement were associated with admission (with the index procedure [+$11,757.31] or readmission [+$31,248.80]), followed by insurance type (relative to Medicare, commercial +$4,183.79), postoperative adverse events (+$2,006.60), and postoperative emergency department visits (+$1,686.89) ( P < 0.0001 for each). Lesser associations were with Elixhauser Comorbidity Index (+$286.67 for each point increase) and age (-$24.65 with each year increase) ( P < 0.001 and P = 0.003, respectively). DISCUSSION: This study assessed a large cohort of lumbar laminotomies/diskectomies and found substantial variations in reimbursement/cost to the healthcare system. The largest increase in reimbursement was associated with admission (with the index procedure or readmission), followed by insurance type, postoperative adverse events, and postoperative emergency department visits. These results highlight the need to balance inpatient versus outpatient surgeries while limiting postoperative readmissions to minimize the costs associated with healthcare delivery.

Background: The onset of the COVID-19 pandemic led to substantial alterations in healthcare delivery and access. In this study, we aimed to evaluate the impact of COVID-19 on the presentation and surgical care of patients with gastrointestinal (GI) cancers. Methods: All patients who underwent GI cancer surgery at a large, tertiary referral center between March 15, 2019 and March 15, 2021 were included. March 15, 2020 was considered the start of the COVID-19 pandemic. Changes in patient, tumor, and treatment characteristics before the pandemic compared to during the pandemic were evaluated. Results: Of 522 patients that met study criteria, 252 (48.3%) were treated before the COVID-19 pandemic. During the first COVID-19 wave, weekly volume of GI cancer cases was one-third lower than baseline (p = 0.041); during the second wave, case volume remained at baseline levels (p = 0.519). There were no demographic or tumor characteristic differences between patients receiving GI cancer surgery before versus during COVID-19 (p > 0.05 for all), and no difference in rate of emergency surgery (p > 0.9). Patients were more likely to receive preoperative chemotherapy during the first six months of the pandemic compared to the subsequent six months (35.6% vs. 15.5%, p < 0.001). Telemedicine was rapidly adopted at the start of the pandemic, rising from 0% to 47% of GI surgical oncology visits within two months. Conclusions: The COVID-19 pandemic caused an initial disruption to the surgical care of GI cancers, but did not compromise stage at presentation. Preoperative chemotherapy and telemedicine were utilized to mitigate the impact of a high COVID-19 burden on cancer care.
RESUMEN
STUDY DESIGN: Retrospective cohort study. OBJECTIVE: The influence that race has on mortality rates in patients with spinal cord tumors is relatively unknown. The aim of this study was to investigate the influence of race on the outcomes of patients with primary malignant or nonmalignant tumors of the spinal cord or spinal meninges. METHODS: The Surveillance, Epidemiology, and End Results (SEER) Registry was used to identify all patients with a code for primary malignant or nonmalignant tumor of the spinal cord (C72.0) or spinal meninges (C70.1) from 1973 through 2016. Racial groups (African-American/Black vs. White) were balanced using propensity-score (PS) matching using a non-parsimonious 1:1 nearest neighbor matching algorithm. Overall survival (OS) estimates were obtained using the Kaplan-Meier method and compared across non-PS-matched and PS-matched groups using log-rank tests. Associations of survival with clinical variables was assessed using doubly robust Cox proportional-hazards (CPH) regression analysis. RESULTS: There were a total of 7,498 patients identified with 648 (6.8%) being African American. African-American patients with primary intradural spine tumors were more likely to die of all causes than were White patients in both the non-PS-matched [HR: 1.26, 95% CI: (1.04, 1.51), P = 0.01] and PS-matched cohorts [HR: 1.64, 95% CI: (1.28, 2.11), P < 0.0001]. On multivariate CPH regression analysis age at diagnosis [HR: 1.03, 95% CI: (1.02, 1.05), P < 0.0001], race [HR: 1.82, 95% CI: (1.22, 2.74), P = 0.004), and receipt of RT [HR: 2.62, 95% CI: (1.56, 4.37), P = 0.0002) were all significantly associated with all-cause mortality, when controlling for other demographic, tumor, and treatment variables. CONCLUSIONS: Our study provides population-based estimates of the prognosis for patients with primary malignant or nonmalignant tumors of the spinal cord or spinal meninges and suggests that race may impact all-cause mortality.
RESUMEN
OBJECTIVE: The Hospital Frailty Risk Score (HFRS) is a metric that measures frailty among patients in large national datasets using ICD-10 codes. While other metrics have been utilized to demonstrate the association between frailty and poor outcomes in spine oncology, none have examined the HFRS. The aim of this study was to investigate the impact of frailty using the HFRS on complications, length of stay, cost of admission, and discharge disposition in patients undergoing surgery for primary tumors of the spinal cord and meninges. METHODS: A retrospective cohort study was performed using the Nationwide Inpatient Sample database from 2016 to 2018. Adult patients undergoing surgery for primary tumors of the spinal cord and meninges were identified using ICD-10-CM codes. Patients were categorized into 2 cohorts based on HFRS score: Non-Frail (HFRS<5) and Frail (HFRS≥5). Patient characteristics, treatment, perioperative complications, LOS, discharge disposition, and cost of admission were assessed. RESULTS: Of the 5955 patients identified, 1260 (21.2%) were Frail. On average, the Frail cohort was nearly 8 years older (P < .001) and experienced more postoperative complications (P = .001). The Frail cohort experienced longer LOS (P < .001), a higher rate of non-routine discharge (P = .001), and a greater mean cost of admission (P < .001). Frailty was found to be an independent predictor of extended LOS (P < .001) and non-routine discharge (P < .001). CONCLUSION: Our study is the first to use the HFRS to assess the impact of frailty on patients with primary spinal tumors. We found that frailty was associated with prolonged LOS, non-routine discharge, and increased hospital costs.
RESUMEN
OBJECTIVE: To understand the variability of surgical attending experience and perspectives regarding informed consent and how it impacts resident education DESIGN: A novel survey was distributed electronically to explore faculty surgeon's personal learning experience, knowledge, clinical practice, teaching preferences and beliefs regarding informed consent. Chi-square and Kruskal-Wallis testing was performed to look for associations and a cluster analysis was performed to elucidate additional patterns among. SETTING: Single, tertiary, university-affiliated health care system (Yale New Haven Health in Connecticut), including 6 teaching hospitals. PARTICIPANTS: Clinical faculty within the Department of Surgery. RESULTS: A total of 85 surgeons responded (49% response rate), representing 17 specialties, both private practice and university and/or hospital-employed, with a range of years in practice. Across all ages, specialties, the most common method for both learning (86%) and teaching (82%) informed consent was observation of the attending. Respondents who stated they learned by observing attendings were more likely to report that they teach by having trainees observe them (OR 8.5, 95% CI 1.3-56.5) and participants who recalled learning by having attendings observe them were more likely to observe their trainees (OR 4.1, 95% CI 1.5-11.2).Cluster analysis revealed 5 different attending phenotypes with significant heterogeneity between groups. A cluster of younger attendings reported the least diverse learning experience and high levels of concern for legal liability and resident competency. They engaged in few strategies for teaching residents. By comparison, the cluster that reported the most diverse learning experience also reported the richest diversity of teaching strategies to residents but rarely allowed residents to perform consent with their patients. Meanwhile, 2 other cluster provided a more balanced experience with some opportunities for practice with patients and some diversity of teaching- these clusters, respectively, consist of older, experienced general surgeons and surgeons in trauma and/or critical care. CONCLUSIONS: Surgeon's demographics, personal experiences, and specialty appear to significantly influence their teaching styles and the educational experience residents receive regarding informed consent.

BACKGROUND: As health care expenditures continue to increase, standardizing health care delivery across geographic regions has been identified as a method to reduce costs. However, few studies have demonstrated how the practice of elective spine surgery varies by geographic location. The aim of this study was to assess the geographic variations in management, complications, and total cost of elective anterior cervical discectomy and fusion (ACDF) for cervical spondylotic myelopathy (CSM). METHODS: The National Inpatient Sample database (2016-2017) was queried using the ICD-10-CM procedural and diagnostic coding systems to identify all adult (≥18 years) patients with a primary diagnosis of CSM undergoing an elective ACDF. Patients were divided into regional cohorts as defined by the U.S. Census Bureau: Northeast, Midwest, South, and West. Weighted patient demographics, Elixhauser comorbidities, perioperative complications, length of stay (LOS), discharge disposition, and total cost of admission were assessed. RESULTS: A total of 17,385 adult patients were identified. While the age (p=0.116) and proportion of female patients (p=0.447) were similar among the cohorts, race (p<0.001) and healthcare coverage (p<0.001) varied significantly. The Northeast had the largest proportion of patients in the 76-100th household income quartile (Northeast: 32.1%; Midwest: 16.9%; South: 15.7%; West: 27.5%, p<0.001). Complication rates were similar between regional cohorts (Northeast: 10.1%; Midwest: 12.2%; South: 10.3%; West: 11.9%, p=0.503), as was LOS (Northeast: 2.2±2.4 days; Midwest: 2.1±2.4 days; South: 2.0±2.5 days; West: 2.1±2.4 days, p=0.678). The West incurred the greatest mean total cost of admission (Northeast: $19,167±10,267; Midwest: $18,903±9,114; South: $18,566±10,152; West: $24,322±15,126, p<0.001). The Northeast had the lowest proportion of patients with a routine discharge (Northeast: 72.0%; Midwest: 84.8%; South: 82.3%; West: 83.3%, p<0.001). The odds ratio for Western hospital region was 3.46 [95% CI: (2.41, 4.96), p<0.001] compared to the Northeast for increased cost. CONCLUSION: Our study suggests that regional variations exist in elective ACDF for CSM, including patient demographics, hospital costs, and nonroutine discharges, while complication rates and LOS were similar between regions.
RESUMEN
OBJECTIVE: The Hospital Frailty Risk Score (HFRS) was developed utilizing ICD-10 diagnostic codes to identify frailty and predict adverse outcomes in large national databases. While other studies have examined frailty in spine oncology, the HFRS has not been assessed in this patient population. The aim of this study was to examine the association of HFRS-defined frailty with complication rates, length of stay (LOS), total cost of hospital admission, and discharge disposition in patients undergoing spine surgery for metastatic spinal column tumors. METHODS: A retrospective cohort study was performed using the years 2016 to 2019 of the National Inpatient Sample (NIS) database. All adult patients (≥ 18 years old) undergoing surgical intervention for metastatic spinal column tumors were identified using the ICD-10-CM diagnostic codes and Procedural Coding System. Patients were categorized into the following three cohorts based on their HFRS: low frailty (HFRS < 5), intermediate frailty (HFRS 5-15), and high frailty (HFRS > 15). Patient demographics, comorbidities, treatment modality, perioperative complications, LOS, discharge disposition, and total cost of hospital admission were assessed. A multivariate logistic regression analysis was used to identify independent predictors of prolonged LOS, nonroutine discharge, and increased cost. RESULTS: Of the 11,480 patients identified, 7085 (61.7%) were found to have low frailty, 4160 (36.2%) had intermediate frailty, and 235 (2.0%) had high frailty according to HFRS criteria. On average, age increased along with progressively worsening frailty scores (p ≤ 0.001). The proportion of patients in each cohort who experienced ≥ 1 postoperative complication significantly increased along with increasing frailty (low frailty: 29.2%; intermediate frailty: 53.8%; high frailty: 76.6%; p < 0.001). In addition, the mean LOS (low frailty: 7.9 ± 5.0 days; intermediate frailty: 14.4 ± 13.4 days; high frailty: 24.1 ± 18.6 days; p < 0.001), rate of nonroutine discharge (low frailty: 40.4%; intermediate frailty: 60.6%; high frailty: 70.2%; p < 0.001), and mean total cost of hospital admission (low frailty: $48,603 ± $29,979; intermediate frailty: $65,271 ± $43,110; high frailty: $96,116 ± $60,815; p < 0.001) each increased along with progressing frailty. On multivariate regression analysis, intermediate and high frailty were each found to be significant predictors of both prolonged LOS (intermediate: OR 3.75 [95% CI 2.96-4.75], p < 0.001; high: OR 7.33 [95% CI 3.47-15.51]; p < 0.001) and nonroutine discharge (intermediate: OR 2.05 [95% CI 1.68-2.51], p < 0.001; high: OR 5.06 [95% CI 1.93-13.30], p = 0.001). CONCLUSIONS: This study is the first to use the HFRS to assess the impact of frailty on perioperative outcomes in patients with metastatic bony spinal tumors. Among patients with metastatic bony spinal tumors, frailty assessed using the HFRS was associated with longer hospitalizations, more nonroutine discharges, and higher total hospital costs.
RESUMEN
Hypotension secondary to autonomic dysfunction is a common complication of acute spinal cord injury (SCI) that may worsen neurologic outcomes. Midodrine, an enteral α-1 agonist, is often used to facilitate weaning intravenous (IV) vasopressors, but its use can be limited by reflex bradycardia. Alternative enteral agents to facilitate this wean in the acute post-SCI setting have not been described. We aim to describe novel application of droxidopa, an enteral precursor of norepinephrine that is approved to treat neurogenic orthostatic hypotension, in the acute post-SCI setting. Droxidopa may be an alternative enteral therapy for those intolerant of midodrine due to reflex bradycardia. We describe two patients suffering traumatic cervical SCI who were successfully weaned off IV vasopressors with droxidopa after failing with midodrine. The first patient was a 64-year-old male who underwent C3-6 laminectomies and fusion after a ten-foot fall resulting in quadriparesis. Post-operatively, the addition of midodrine in an attempt to wean off IV vasopressors resulted in significant reflexive bradycardia. Treatment with droxidopa facilitated rapidly weaning IV vasopressors and transfer to a lower level of care within 72 hours of treatment initiation. The second patient was a 73-year-old male who underwent C3-5 laminectomies and fusion for a traumatic hyperflexion injury causing paraplegia. The addition of midodrine resulted in severe bradycardia, prompting consideration of pacemaker placement. However, with the addition of droxidopa, this was avoided, and the patient was weaned off IV vasopressors on dual oral therapy with midodrine and droxidopa. Droxidopa may be a viable enteral therapy to treat hypotension in patients after acute SCI who are otherwise not tolerating midodrine in order to wean off IV vasopressors. This strategy may avoid pacemaker placement and facilitate shorter stays in the intensive care unit, particularly for patients who are stable but require continued intensive care unit admission for IV vasopressors, which can be cost ineffective and human resource depleting.
RESUMEN
STUDY DESIGN: Retrospective cohort study. OBJECTIVE: The aim of this study was to determine the impact age has on LOS and discharge disposition following elective ACDF for cervical spondylotic myelopathy (CSM). METHODS: A retrospective cohort study was performed using the National Inpatient Sample (NIS) database from 2016 and 2017. All adult patients >50 years old undergoing ACDF for CSM were identified using the ICD-10-CM diagnosis and procedural coding system. Patients were then stratified by age: 50 to 64 years-old, 65 to 79 years-old, and greater than or equal to 80 years-old. Weighted patient demographics, comorbidities, perioperative complications, LOS, discharge disposition, and total cost of admission were assessed. RESULTS: A total of 14 865 patients were identified. Compared to the 50-64 and 65-79 year-old cohorts, the 80+ years cohort had a significantly higher rate of postoperative complication (50-64 yo:10.2% vs. 65-79 yo:12.6% vs. 80+ yo:18.9%, P = 0.048). The 80+ years cohort experienced significantly longer hospital stays (50-64 yo: 2.0 ± 2.4 days vs. 65-79 yo: 2.2 ± 2.8 days vs. 80+ yo: 2.3 ± 2.1 days, P = 0.028), higher proportion of patients with extended LOS (50-64 yo:18.3% vs. 65-79 yo:21.9% vs. 80+ yo:28.4%, P = 0.009), and increased rates of non-routine discharges (50-64 yo:15.1% vs. 65-79 yo:23.0% vs. 80+ yo:35.8%, P < 0.001). On multivariate analysis, age 80+ years was found to be a significant independent predictor of extended LOS [OR:1.97, 95% CI:(1.10,3.55), P = 0.023] and non-routine discharge [OR:2.46, 95% CI:(1.44,4.21), P = 0.001]. CONCLUSIONS: Our study demonstrates that octogenarian age status is a significant independent risk factor for extended LOS and non-routine discharge after elective ACDF for CSM.
RESUMEN
STUDY DESIGN: This is a retrospective cohort study. OBJECTIVE: The aim of this study was to investigate patient risk factors and health care resource utilization associated with postoperative dysphagia following elective anterior cervical discectomy and fusion (ACDF) for cervical spondylotic myelopathy. SUMMARY OF BACKGROUND DATA: There is a paucity of data on factors predisposing patients to dysphagia and the burden this complication has on health care resource utilization following ACDF. METHODS: A retrospective cohort study was performed using the Nationwide Inpatient Sample (NIS) database from 2016 to 2017. All adult (above 18 y old) patients undergoing ACDF for cervical spondylotic myelopathy were identified using the ICD-10-CM diagnosis and procedural coding system. Patients were then categorized by whether they had a recorded postoperative dysphagia or no dysphagia. Weighted patient demographics, comorbidities, perioperative complications, length of hospital stay (LOS), discharge disposition, and total cost of admission were assessed. A multivariate stepwise logistic regression was used to determine both the odds ratio for risk-adjusted postoperative dysphagia as well as extended LOS. RESULTS: A total of 17,385 patients were identified, of which 1400 (8.1%) experienced postoperative dysphagia. Compared with the No-Dysphagia cohort, the Dysphagia cohort had a greater proportion of patients experiencing a complication (P=0.004), including 1 complication (No-Dysphagia: 2.9% vs. Dysphagia: 6.8%), and >1 complication (No-Dysphagia: 0.3% vs. Dysphagia: 0.4%). The Dysphagia cohort experienced significantly longer hospital stays (No-Dysphagia: 1.9±2.1 d vs. Dysphagia: 4.2±4.3 d, P<0.001), higher total cost of admission (No-Dysphagia: $19,441±10,495 vs. Dysphagia: $25,529±18,641, P<0.001), and increased rates of nonroutine discharge (No-Dysphagia: 16.5% vs. Dysphagia: 34.3%, P<0.001). Postoperative dysphagia was found to be a significant independent risk factor for extended LOS on multivariate analysis, with an odds ratio of 5.37 (95% confidence interval: 4.09, 7.05, P<0.001). CONCLUSION: Patients experiencing postoperative dysphagia were found to have significantly longer hospital LOS, higher total cost of admission, and increased nonroutine discharge when compared with the patients who did not. LEVEL OF EVIDENCE: Level III.

OBJECTIVE: In various spinal surgeries, non-routine discharges have been associated with inferior outcomes. However, there exists a paucity of data regarding the relationship between non-routine discharge and quality of care among patients with spondylolisthesis. The aim of this study was to identify independent predictors for non-routine discharge following spinal decompression and fusion for lumbar spondylolisthesis. METHODS: A retrospective cohort study was performed using the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database from 2010 through 2016. Adult patients (≥18 years old) who underwent spinal decompression and fusion for lumbar spondylolisthesis were identified using ICD-9-CM diagnosis and CPT procedural coding systems. The study population was divided into two cohorts based on discharge disposition: routine (RD) and non-routine discharge (NRD). Patient demographics, comorbidities, adverse events, LOS, reoperation, and readmission were assessed. A multivariate logistic regression model was used to identify the independent predictors of non-home discharge and 30-day unplanned readmission. RESULTS: A total of 5252 patients were identified, of which 4316 (82.2%) had a RD and 936 (18.8%) had a NRD. The NRD cohort tended to be older (p < 0.001) and have a higher BMI (p < 0.001). Patients who experienced a NRD had a longer LOS (NRD: 4.7 ± 3.7 days vs RD: 3.1 ± 2.0 days, p < 0.001), a higher proportion of adverse events (p < 0.001), higher rates of reoperation (p = 0.005) and unplanned 30-day readmission rates (p < 0.001). On multivariate regression analysis, age [OR: 1.08, 95% CI (1.06-1.10), p < 0.001], female sex [OR: 2.01, 95% (1.51-2.69), p < 0.001], non-Hispanic Black race/ethnicity [OR: 2.10, 95% CI (1.36-3.24), p = 0.001], BMI [OR: 1.03, 95% CI (1.01-1.05), p = 0.007], dependent functional status [OR: 3.33, 95% CI (1.59 - 6.99), p = 0.001], malnourishment [OR: 2.14, 95% CI (1.27-3.62), p = 0.005], and LOS [OR: 1.26, 95% CI (1.18-1.33), p < 0.001] were all independent predictors for NRD. However, NRD did not independently predict an unplanned 30-day readmission on multivariate analysis. CONCLUSION: In our study we found that on univariate analysis NRD was associated with increased adverse events, length of stay and 30-day unplanned readmission. When controlling for patient- and hospital-related factors, we found that female sex, non-Hispanic Black race, BMI, dependent functional status, malnourishment and longer LOS were independently associated with NRD. However, NRD did not independently predict an unplanned 30-day readmission.

OBJECTIVE: The aim of this study was to determine if baseline frailty was an independent predictor of adverse events (AEs) and in-hospital mortality in patients being treated for acute cervical spinal cord injury (SCI). METHODS: A retrospective cohort study was performed using the National Trauma Database (NTDB) from 2017. Adult patients (>18 years old) with acute cervical SCI were identified using the International Classification of Diseases, Tenth Revision, Clinical Modification diagnostic and procedural coding systems. Patients were categorized into 3 cohorts based on the criteria of the 5-item modified frailty index (mFI-5): mFI = 0, mFI = 1, or mFI≥2. Patient demographics, comorbidities, type of injury, diagnostic and treatment modality, AEs, and in-patient mortality were assessed. A multivariate logistic regression analysis was used to identify independent predictors of in-hospital AEs and mortality. RESULTS: Of 8986 patients identified, 4990 (55.5%) were classified as mFI = 0, 2328 (26%) as mFI = 1, and 1668 (18.5%) as mFI≥2. On average, the mFI≥2 cohort was 5 years older than the mFI = 1 cohort and 22 years older than the mFI = 0 cohort (P < 0.001). Most patients in each cohort sustained either complete SCI or central cord syndrome after a fall or transport accident (mFI = 0, 77.31% vs. mFI = 1, 89.5% vs. mFI≥2, 93.65%). With respect to in-hospital events, the proportion of patients who experienced any AE increased significantly along with frailty score (mFI = 0, 30.42% vs. mFI = 1, 31.74% vs. mFI≥2, 34.95%; P < 0.001). In-hospital mortality followed a similar trend, increasing with frailty score (mFI = 0, 10.53% vs. mFI = 1, 11.33% vs. mFI≥2, 16.23%; P < 0.001). On multivariate regression analysis, both mFI = 1 1.21 (odds ratio [OR], 1.21; 95% confidence interval [CI], 1.05-1.4; P = 0.008) and mFI≥2 (OR, 1.23; 95% CI, 1.05-1.45; P = 0.012) predicted AEs, whereas only mFI≥2 was found to be a predictor for in-hospital mortality (OR, 1.45; 95% CI, 1.14-1.83; P = 0.002). CONCLUSIONS: Increasing frailty is associated with an increased risk of AEs and in-hospital mortality in patients undergoing treatment for cervical SCI.

OBJECTIVE: The prevalence of obesity continues to rise in the United States at a disparaging rate. Although previous studies have attempted to identify the influence obesity has on short-term outcomes following elective spine surgery, few studies have assessed the impact on discharge disposition following anterior cervical discectomy and fusion (ACDF) for cervical spondylotic myelopathy (CSM). The aim of this study was to determine whether obesity impacts the hospital management, cost, and discharge disposition after elective ACDF for adult CSM. METHODS: The National Inpatient Sample database was queried using the International Classification of Diseases, 10th revision, Clinical Modification, coding system to identify all (≥18 years) patients with a primary diagnosis of CSM undergoing an elective ACDF for the years 2016 and 2017. Discharge weights were used to estimate national demographics, Elixhauser comorbidities, complications, length of stay, total cost of admission, and discharge disposition. RESULTS: There were 17,385 patients included in the study, of whom 3035 (17.4%) had obesity (no obesity: 14,350; obesity: 3035). The cohort with obesity had a significantly greater proportion of patients with 3 or more comorbidities compared with the cohort with no obesity (no obesity: 28.1% vs. obesity: 43.5%, P < 0.001). The overall complication rates were greater in the cohort with obesity (no obesity: 10.3% vs. obesity: 14.3%, P = 0.003). On average, the cohort with obesity incurred a total cost of admission $1154 greater than the cost of the cohort with no obesity (no obesity: $19,732 ± 11,605 vs. obesity: $20,886 ± 10,883, P = 0.034) and a significantly greater proportion of nonroutine discharges (no obesity: 16.6% vs. obesity: 24.2%, P < 0.001). In multivariate regression analysis, obesity, age, race, health care coverage, hospital bed size, region, comorbidity, and complication rates all were independently associated with nonroutine discharge disposition. CONCLUSIONS: Our study demonstrates that obesity is an independent predictor for nonroutine discharge disposition following elective anterior cervical discectomy and fusion for cervical spondylotic myelopathy.

OBJECTIVE: The aim of this study was to determine if race was an independent predictor of extended length of stay (LOS), nonroutine discharge, and increased health care costs after surgery for spinal intradural/cord tumors. METHODS: A retrospective cohort study was performed using the National Inpatient Sample database from 2016 to 2017. All adult (>18 years old) inpatients who underwent surgical intervention for a benign or malignant spinal intradural/cord tumor were identified using International Classification of Diseases, Tenth Revision, Clinical Modification diagnosis and procedural coding systems. Patients were then categorized based on race: White, African American (AA), Hispanic, and other. Postoperative complications, LOS, discharge disposition, and total cost of hospitalization were assessed. A backward stepwise multivariable logistic regression analysis was used to identify independent predictors of extended LOS and nonroutine discharge disposition. RESULTS: Of 3595 patients identified, there were 2620 (72.9%) whites (W), 310 (8.6%) AAs/blacks, 275 (7.6%) Hispanic (H), and 390 (10.8%) other (O). Postoperative complication rates were similar among the cohorts (P = 0.887). AAs had longer mean (W, 5.4 ± 4.2 days vs. AA, 8.9 ± 9.5 days vs. H, 5.9 ± 3.9 days vs. O, 6.1 ± 3.9 days; P = 0.014) length of hospitalizations than the other cohorts. The overall incidence of nonroutine discharge was 55% (n = 1979), with AA race having the highest rate of nonroutine discharges (W, 53.8% vs. AA, 74.2% vs. H, 45.5% vs. O, 43.6%; P = 0.016). On multivariate regression analysis, AA race was the only significant racial independent predictor of nonroutine discharge disposition (odds ratio, 3.32; confidence interval, 1.67-6.60; P < 0.001), but not extended LOS (P = 0.209). CONCLUSIONS: Our study indicates that AA race is an independent predictor of nonroutine discharge disposition in patients undergoing surgical intervention for a spinal intradural/cord tumor.

OBJECTIVE: The aim of this study was to compare complication rates, length of stay (LOS), and hospital costs after spine surgery for bony spine tumors and intradural spinal neoplasms. METHODS: A retrospective cohort study was performed using the National Inpatient Sample database from 2016 to 2017. All adult inpatients who underwent surgical intervention for a primary intradural spinal tumor or primary/metastatic bony spine tumor were identified using International Classification of Diseases, Tenth Revision, Clinical Modification diagnosis/procedural coding systems. Patient demographics, comorbidities, intraoperative variables, complications, LOS, discharge disposition, and total cost of hospitalization were assessed. Backward stepwise multivariable logistic regression analyses were used to identify independent predictors of perioperative complication, extended LOS (≥75th percentile), and increased cost (≥75th percentile). RESULTS: A total of 9855 adult patients were included in the study; 3850 (39.1%) were identified as having a primary intradural spinal tumor and 6005 (60.9%) had a primary or metastatic bony spine tumor. Those treated for bony tumors had more comorbidities (≥3, 67.8% vs. 29.2%) and more commonly experienced ≥1 complications (29.9% vs. 7.9%). Multivariate analyses also showed those in the bony spine cohort had a higher odds of experiencing ≥1 complications (odds ratio [OR], 4.26; 95% confidence interval [CI], 3.04-5.97; P < 0.001), extended LOS (OR, 2.44; 95% CI, 1.75-3.38; P < 0.001), and increased cost (OR, 5.32; 95% CI, 3.67-7.71; P < 0.001). CONCLUSIONS: Relative to patients being treated for primary intradural tumors, those undergoing spine surgery for bony spine tumors experience significantly higher risk for perioperative complications, extended LOS, and increased cost of hospital admission. Further identification of patient and treatment characteristics that may optimize management of spine oncology may reduce adverse outcomes, improve patient care, and reduce health care resources.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: The aim of this study was to investigate differences in 30- and 90-day readmissions for spine metastases treated with decompression and/or fusion spine surgery in a nationwide readmission database. SUMMARY OF BACKGROUND DATA: Patients with metastases to the spine represent a particularly vulnerable patient group that may encounter frequent readmissions. However, the 30- and 90-day rates for readmission following surgery for spine metastases have not been well described. METHODS: The Nationwide Readmission Database years 2013 to 2015 was queried. Patients were grouped by no readmission (non-R), readmission within 30 days (30-R), and readmission within 31 to 90 days (90-R). Weighted multivariate analysis assessed impact of treatment approach and clinical factors associated with 30- and 90-day readmissions. RESULTS: There were a total of 4423 patients with a diagnosis of spine metastases identified who underwent spine surgery, of which 1657 (37.5%) encountered either a 30-or 90-day unplanned readmission (30-R: nâ=â1068 [24-.1%]; 90-R: nâ=â589 [13.3%]; non-R: nâ=â2766). The most prevalent inpatient complications observed were postoperative infection (30-R: 16.3%, 90-R: 14.3%, non-R: 11.5%), acute post-hemorrhagic anemia (30-R: 13.4%, 90-R: 14.2%, non-R: 14.5%), and genitourinary complication (30-R: 5.7%, 90-R: 2.9%, non-R: 6.2%). The most prevalent 30-day and 90-day reasons for admission were sepsis (30-R: 10.2%, 90-R: 10.8%), postoperative infection (30-R: 13.7%, 90-R: 6.5%), and genitourinary complication (30-R: 3.9%, 90-R: 4.1%). On multivariate regression analysis, surgery type, age, hypertension, and renal failure were independently associated with 30-day readmission; rheumatoid arthritis/collagen vascular diseases, and coagulopathy were independently associated with 90-day readmission. CONCLUSION: In this study, we demonstrate several patient-level factors independently associated with unplanned hospital readmissions after surgical treatment intervention for spine metastases. Furthermore, we find that the most common reasons for readmission are sepsis, postoperative infection, and genitourinary complications.Level of Evidence: 3.

OBJECTIVE: The aim of this study was to characterize the payments made by medical industry to neurosurgeons from 2014 to 2018. METHODS: A retrospective study was performed from January 1, 2014 to December 31, 2018 of the Open Payments Database. Collected data included the total number of industry payments, the aggregate value of industry payments, and the mean value of each industry payment made to neurosurgeons per year over the 5-year period. RESULTS: A total of 105,150 unique surgeons, with 13,668 (12.99%) unique neurosurgeons, were identified to have received an industry payment during 2014-2018. Neurosurgeons were the second highest industry-paid surgical specialty, with a total 421,151 industry payments made to neurosurgeons, totaling $477,451,070. The mean average paid amount per surgeon was $34,932 (±$936,942). The largest proportion of payments were related to food and beverage (75.5%), followed by travel and lodging (14.9%), consulting fees (3.5%), nonconsulting service fees (2.1%), and royalties or licensing (1.9%), totaling 90.4% of all industry payments to neurologic surgeons. Summed across the 5-year period, the largest paid source types were royalties and licensing (64.0%; $305,517,489), consulting fees (11.8%; $56,445,950), nonconsulting service fees (7.3%; $34,629,109), current or prospective investments (6.8%, $32,307,959), and travel and lodging (4.8%, $22,982,165). CONCLUSIONS: Our study shows that over the most recent 5-year period (2014-2018) of the Centers for Medicare and Medicaid Services Open Payments Database, there was a decreasing trend of the total number of payments, but an increasing trend of the total amount paid to neurosurgeons.

OBJECTIVE: The outcomes of patients treated on the COVID-minimal pathway were evaluated during a period of surging COVID-19 hospital admissions, to determine the safety of continuing to perform urgent operations during the pandemic. SUMMARY OF BACKGROUND DATA: Crucial treatments were delayed for many patients during the COVID-19 pandemic, over concerns for hospital-acquired COVID-19 infections. To protect cancer patients whose survival depended on timely surgery, a "COVID-minimal pathway" was created. METHODS: Patients who underwent a surgical procedure on the pathway between April and May 2020 were evaluated. The "COVID-minimal surgical pathway" consisted of: (A) evolving best-practices in COVID-19 transmission-reduction, (B) screening patients and staff, (C) preoperative COVID-19 patient testing, (D) isolating pathway patients from COVID-19 patients. Patient status through 2 weeks from discharge was determined as a reflection of hospital-acquired COVID-19 infections. RESULTS: After implementation, pathway screening processes excluded 7 COVID-19-positive people from interacting with pathway (4 staff and 3 patients). Overall, 122 patients underwent 125 procedures on pathway, yielding 83 admissions (42 outpatient procedures). The median age was 64 (56-79) and 57% of patients were female. The most common surgical indications were cancer affecting the uterus, genitourinary tract, colon, lung or head and neck. The median length of admission was 3 days (1-6). Repeat COVID-19 testing performed on 27 patients (all negative), including 9 patients evaluated in an emergency room and 8 readmitted patients. In the postoperative period, no patient developed a COVID-19 infection. CONCLUSIONS: A COVID-minimal pathway comprised of physical space modifications and operational changes may allow urgent cancer treatment to safely continue during the COVID-19 pandemic, even during the surge-phase.

OBJECTIVE: The aim of this study was to investigate whether race is an independent predictor of extended length of stay (LOS) after elective anterior cervical discectomy and fusion (ACDF) for cervical spondylotic myelopathy (CSM). METHODS: A retrospective cohort study was performed using the National Inpatient Sample database from 2016 to 2017. All adult patients undergoing ACDF for CSM were identified using the International Classification of Diseases, Tenth Revision, Clinical Modification coding system. RESULTS: A total of 15,400 patients were identified, of whom 13,250 (86.0%) were Caucasian (C) and 2150 (14.0%) were African American (AA). The C cohort tended to be older, whereas the AA cohort had 2 times as many patients in the 0-25th income quartile. The prevalence of comorbidities was greater in the AA cohort. Intraoperative fusion levels were similar between the cohorts, whereas the AA cohort had a higher rate of cerebrospinal fluid leak/dural tear. In relation to the number of complications, the C cohort had a lower rate compared with the AA cohort (P = 0.006), including no complication (89.4% vs. 85.3%), 1 complication (9.9% vs. 12.8%), and >1 complication (0.7% vs. 1.9%). The AA cohort experienced significantly longer hospital stays (C, 1.9 ± 2.3 days vs. AA, 2.7 ± 3.5; P < 0.001), greater proportion of extended LOS (C, 17.5% vs. AA, 29.1%; P < 0.001) and nonroutine discharges (C, 16.1% vs. AA, 28.6%; P < 0.001). AA race was a significant independent risk factor for extended LOS (odds ratio, 1.98; 95% confidence interval, 1.50-2.61; P < 0.001). CONCLUSIONS: Our study suggests that AA patients have a significantly higher risk of prolonged LOS after elective ACDF for CSM compared with C patients.

STUDY DESIGN: This is a retrospective cohort study. OBJECTIVE: The aim of this study was to assess the patient-level risk factors associated with 30- and 90-day unplanned readmissions following elective anterior cervical decompression and fusion (ACDF) or cervical disk arthroplasty (CDA). SUMMARY OF BACKGROUND DATA: For cervical disk pathology, both ACDF and CDA are increasingly performed nationwide. However, relatively little is known about the adverse complications and rates of readmission for ACDF and CDA. METHODS: A retrospective cohort study was performed using the Nationwide Readmission Database from the years 2013 to 2015. All patients undergoing either CDA or ACDF were identified using the International Classification of Diseases, Ninth Revision, Clinical Modification coding system. Unique patient linkage numbers were used to follow patients and to identify 30- and 31-90-day readmission rates. Patients were grouped by no readmission (Non-R), readmission within 30 days (30-R), and readmission within 31-90 days (90-R). RESULTS: There were a total of 13,093 index admissions with 856 (6.5%) readmissions [30-R: n=532 (4.0%); 90-R: n=324 (2.5%)]. Both overall length of stay and total cost were greater in the 30-R cohort compared with 90-R and Non-R cohorts. The most prevalent 30- and 90-day complications seen among the readmitted cohorts were infection, genitourinary complication, and device complication. On multivariate regression analysis, age, Medicaid status, medium and large hospital bed size, deficiency anemia, and any complication during index admission were independently associated with increased 30-day readmission. Whereas age, large hospital bed size, coagulopathy, and any complication during the initial hospitalization were independently associated with increased 90-day readmission. CONCLUSION: Our nationwide study identifies the 30- and 90-day readmission rates and several patient-related risk factors associated with unplanned readmission after common anterior cervical spine procedures. LEVEL OF EVIDENCE: Level III.
