- Abstract
Background: High-energy traumatic sacral fractures, particularly U-type or AOSpine classification type C fractures, may lead to significant functional deficits. Traditionally, spinopelvic fixation for unstable sacral fractures was performed with open reduction and fixation, but robotic-assisted minimally invasive surgical methods now present new, less invasive approaches. The objective here was to present a series of patients with traumatic sacral fractures treated with robotic-assisted minimally invasive spinopelvic fixation and discuss early experience, considerations, and technical challenges., Methods: Between June 2022 and January 2023, 7 consecutive patients met the inclusion criteria. Intraoperative fluoroscopic images were merged with intraoperative computed tomography images using a robotic system to plan the trajectories for placement of bilateral lumbar pedicle and iliac screws. Intraoperative computed tomography was performed after pedicle and pelvic screw insertion to confirm appropriate placement before insertion of rods percutaneously without the need for a side connector., Results: The cohort consisted of 7 patients (4 female, 3 male) with ages ranging from 20 to 74. Intraoperatively, the mean blood loss was 85.7 ± 84.0 mL, and mean operative time was 178.4 ± 63.9 minutes. There were no complications in 6 patients; 1 patient experienced both a medially breached pelvic screw and a complicated rod pullout. All patients were safely discharged to their homes or an acute rehabilitation facility., Conclusions: Our early experience reveals that robotic-assisted minimally invasive spinopelvic fixation for traumatic sacral fractures is a safe and feasible treatment option with the potential to improve outcomes and reduce complications., (Copyright © 2023 Elsevier Inc.

- Abstract
Background: The accuracy of pedicle screws placed with instrument tracking and robotic navigation are individually comparable or superior to placement using standard fluoroscopy, however head-to-head comparisons between these adjuncts in a similar surgical population have yet to be performed., Methods: Consecutive patients undergoing percutaneous thoracic and lumbosacral spinal instrumentation were retrospectively enrolled. Instrumentation was performed using either fluoroscopy-based instrument tracking system (TrackX, TrackX Technologies) or robotic-navigation (ExcelsiusGPS, Globus Medical). Postinstrumentation computed tomography scans were graded for breach according to the Gertzbein-Robbins scale, with "acceptable" screws deemed as Grade A or B and "unacceptable" screws deemed as Grades C through E. Accuracy data was compared between both instrumentation modalities., Results: Fifty-three patients, comprising a total of 250 screws (167 robot, 83 instrument tracking) were included. The overall accuracy between both modalities was similar, with 96.4% and 97.6% of screws with acceptable accuracy between instrument tracking and robotic navigation, respectively (I-squared 0.30, df = 1, P = 0.58). Between instrument tracking and robotic navigation, 92.8% and 95.8% of screws received Grade A, 3.6% and 1.8% a Grade B, 1.2% and 1.2% a Grade C, 1.2% and 0.6% a Grade D, and 1.2% and 0.6% a Grade E, respectively. The robot was abandoned intraoperatively in 2 cases due to unrecoverable registration inaccuracy or software failure, leading to abandonment of 8 potential screws (4.8%)., Conclusions: In a similar patient population, there is a similarly high degree of instrumentation accuracy between fluoroscopy-based instrument tracking and robotic navigation. There is a rare chance for screw breach with either surgical adjunct., (Copyright © 2023 Elsevier Inc. All rights reserved.)

- Abstract
In recent years, physicians and institutions have come to recognize the increasing opioid epidemic in the United States, thus prompting a dramatic shift in opioid prescribing patterns. The lack of well-studied alternative treatment regimens has led to a substantial burden of opioid addiction in the United States. These forces have led to a huge economic burden on the country. The spine surgery population is particularly high risk for uncontrolled perioperative pain, because most patients experience chronic pain preoperatively and many patients continue to experience pain postoperatively. Overall, there is a large incentive to better understand comprehensive multimodal pain management regimens, particularly in the spine surgery patient population. The goal of this review is to explore trends in pain symptoms in spine surgery patients, overview the best practices in pain medications and management, and provide a concise multimodal and behavioral treatment algorithm for pain management, which has since been adopted by a high-volume tertiary academic medical center., (Copyright © 2022 Elsevier Inc.

- Abstract
Background: Intraoperative computed tomography (CT) is becoming more widely utilized in spine fusion surgeries. The use of CT-based image guidance has been shown to increase the accuracy in instrumentation placement and to reduce the rate of reoperation. However, incidental findings that are obvious in retrospect are still missed in spinal fusion surgeries due to the concept of inattentional blindness and surgeons' preoccupation with the main objective of intraoperative CT (i.e. instrumentation accuracy)., Case Description: The first case describes a 60-year-old male who underwent posterior spinal laminectomy and interbody fusions from L2-L5. Intraoperative CT confirmed appropriate placement of hardware. However, when he was transferred out to the care unit and extubated, he developed a severe headache for which the source was confirmed to be a pneumocephalus from durotomy and cerebrospinal fluid leakage on repeat CT. A retrospective review of his intraoperative CT demonstrated the intrathecal air at L5-S1 interlaminar space that was missed on evaluation during surgery. The second case describes a 68-year-old female who was treated with a successful T4 to pelvis instrumentation and fusion with vertebral column resection at T10 confirmed with imaging. Postoperatively, she developed rapidly progressive oxygen desaturation and was found to have a pneumothorax which had been present on the intraoperative imaging., Conclusion: This case report of two patients with missed intraoperative findings demonstrates the importance of looking beyond instrumentation placement and evaluating the entire intraoperative CT imaging to find abnormalities that could complicate the patients' postoperative recovery and overall hospital stay., (Copyright © 2020 Elsevier Inc.

- Abstract
Background: The incidence of metastatic spine disease (MSD) is increasing among cancer patients. Given the poor outcomes and high rates of morbidity associated with MSD, it is important to determine demographic factors that could impact interventions and outcomes for this patient population. The objectives of this study were to compare in-hospital mortality and complication rates, clinical presentation, and interventions between female and male patients diagnosed with MSD., Methods: Patient data were collected from the United States National Inpatient Sample (NIS) database from the years 2012-2014. Descriptive statistics were used to compare data from 51,800 cases; subsequently, multivariable logistic regression analyses were conducted to assess the effect of gender on outcomes., Results: Males had significantly higher rates of in-hospital mortality (OR 1.30; 95 % CI 1.09-1.56, p = 0.004) and were more likely to have received surgical intervention than females (OR 1.34; 95 % CI 1.16-1.55, p < 0.001). Additionally, female patients were more likely to present with vertebral compression fracture (p < 0.001), while metastatic spinal cord compression (MSCC) and paralysis were more common in male patients (p < 0.001). There was no significant difference in rates of in-hospital complications between female and male patients., Conclusion: Given the significant differences in mortality, disease course, treatment, and in-hospital complications between female and male patients diagnosed with MSD, additional prospective studies are necessary to understand how to meaningfully incorporate these differences into clinical care and prognostication going forward., (Copyright © 2020 Elsevier Ltd.

- Abstract
Background Context: Preoperative optimization of medical comorbidities prior to spinal surgery is becoming an increasingly important intervention in decreasing postoperative complications and ensuring a satisfactory postoperative course. The treatment of preoperative anemia is based on guidelines made by the American College of Cardiology (ACC), which recommends packed red blood cell transfusion when hematocrit is less than 21% in patients without cardiovascular disease and 24% in patients with cardiovascular disease. The literature has yet to quantify the risk profile associated with preoperative pRBC transfusion., Purpose: To determine the incidence of complications following preoperative pRBC transfusion in a cohort of patients undergoing spine surgery., Study Design: Retrospective review of a national surgical database., Patient Sample: The national surgical quality improvement program database OUTCOME NEASURES: Postoperative physiologic complications after a preoperative transfusion. Complications were defined as the occurrence of any DVT, PE, stroke, cardiac arrest, myocardial infarction, longer length of stay, need for mechanical ventilation greater than 48 h, surgical site infections, sepsis, urinary tract infections, pneumonia, or higher 30-day mortality., Methods: The national surgical quality improvement program database was queried, and patients were included if they had any type of spine surgery and had a preoperative transfusion., Results: Preoperative pRBC transfusion was found to be protective against complications when the hematocrit was less than 20% and associated with more complications when the hematocrit was higher than 20%. In patients with a hematocrit higher than 20%, pRBC transfusion was associated with longer lengths of stay, and higher rates of ventilator dependency greater than 48 h, pneumonia, and 30-day mortality., Conclusion: This is the first study to identify an inflection point in determining when a preoperative pRBC transfusion may be protective or may contribute to complications. Further studies are needed to be conducted to stratify by the prevalence of cardiovascular disease., (Copyright © 2020 Elsevier B.V. All rights reserved.)

- Abstract
Background: Aneurysms of the anterior spinal artery are extremely rare. Unlike intracranial saccular aneurysms, they do not occur at branch points, are typically pseudoaneurysms, and rupture secondary to a dissection. They typically present with subarachnoid hemorrhage and demonstrate clinical and radiographic improvement over time without treatment., Methods: We present here the first case to date of a ruptured anterior spinal artery aneurysm with clinical and radiographic progression treated with Onyx embolization. Our patient was unique in the presentation with acute onset of spinal cord injury American Spinal Injury Association B and an extensive thoracolumbar subdural hematoma., Results: An emergent skip-level laminectomy and subdural decompression were performed with no improvement in examination. This was followed by progressive radiographic enlargement of the aneurysm, treated successfully with Onyx embolization., Conclusions: We analyze this case and review the literature on thoracic anterior spinal artery and artery of Adamkiewicz aneurysms., (Copyright © 2020 Elsevier Inc.

- Abstract
Spinal alignment, particularly with respect to spinopelvic parameters, is highly correlated with morbidity and health-related quality-of-life outcomes. Although the importance of spinal alignment has been emphasized in the deformity literature, spinopelvic parameters have not been considered in the context of spine oncology. Because the aim of oncologic spine surgery is mostly palliative, consideration of spinopelvic parameters could improve postoperative outcomes in both the primary and metastatic tumor population by taking overall vertebral stability into account. This review highlights the relevance of focal and global spinal alignment, particularly related to spinopelvic parameters, in the treatment of spine tumors., (Copyright © 2019 Elsevier Inc.

- Abstract
Objective: Previous studies have identified the impact of affective disorders on preoperative and postoperative perception of pain. However, there is a scarcity of data identifying the impact of affective disorders on postdischarge narcotic refills. The aim of this study was to determine whether patients with affective disorders have more narcotic refills after complex spinal fusion for deformity correction., Methods: The medical records of 121 adult (≥18 years old) spine deformity patients undergoing elective, primary complex spinal fusion (≥5 level) for deformity correction at a major academic institution from 2010 to 2015 were reviewed. Patient demographics, comorbidities, intraoperative and postoperative complication rates, baseline and postoperative patient-reported pain scores, ambulatory status, and narcotic refills were collected for each patient. The primary outcome was the rate of 6-week and 3-month narcotic refills., Results: Of the 121 patients, 43 (35.5%) had a clinical diagnosis of anxiety or depression (affective disorder) (AD n = 43; No-AD n = 78). Preoperative narcotic use was significantly higher in the AD cohort (AD 65.9% vs. No-AD 37.7%, P = 0.0035). The AD cohort had significantly higher pain scores at baseline (AD 6.5 ± 2.9 vs. No-AD 4.7 ± 3.1, P = 0.004) and at the first postoperative pain score reported (AD 6.7 ± 2.6 vs. No-AD 5.6 ± 2.9, P = 0.049). However, there were no significant differences in narcotic refills at 6 weeks (AD 34.9% vs. No-AD 25.6%, P = 0.283) and 3 months (AD 23.8% vs. No-AD 17.4%, P = 0.411) after discharge between the cohorts., Conclusions: Our study suggests that whereas spinal deformity patients with affective disorders may have a higher baseline perception of pain and narcotic use, the impact of affective disorders on narcotic refills at 6 weeks and 3 months may be minimal after complex spinal fusion., (Copyright © 2019 Elsevier Inc.

- Abstract
Objective: The widespread over-use of narcotics has been increasing. However, whether narcotic use impacts surgical outcomes after complex spinal fusion remains understudied. The aim of this study was to evaluate whether there is an association between preoperative narcotic use with perioperative complication rates, patient-reported pain scores, and ambulatory status after complex spinal fusions., Methods: The medical records of 134 adult (age ≥18 years) patients with spinal deformity undergoing elective, primary complex spinal fusion (≥5 levels) for deformity correction in a major academic institution from 2005-2015 were reviewed. Patient demographics, comorbidities, intraoperative and postoperative complication rates, pain scores, and ambulatory status were collected for each patient., Results: Patient demographics and comorbidities were similar between both cohorts, except that the Narcotic-User cohort had a greater mean age (57.5 years vs. 50.7 years; P = 0.045) and prevalence of depression (39.4% vs. 16.2%; P = 0.003). Complication rates were similar between both cohorts. The Narcotic-User cohort had significantly higher pain scores at baseline (6.7 ± 2.4 vs. 4.0 ± 3.4; P < 0.001) and at the first postoperative pain score reported (6.7 ± 2.8 vs. 5.3 ± 2.9; P = 0.013), but had a significantly greater improvement from baseline to last pain score (Narcotic-User: -2.5 ± 3.9 vs. Non-User: -0.5 ± 4.7; P = 0.031). The Narcotic-User cohort had significantly greater ambulation on the first postoperative ambulatory day compared with the Non-User cohort (103.8 ± 144.4 vs. 56.4 ± 84.0; P = 0.031)., Conclusions: Our study suggests that the preoperative use of narcotics may impact patient perception of pain and improvement after complex spinal fusions (≥5 levels). Consideration of patients' narcotic status preoperatively may facilitate tailored pain management and physical therapy regimens., (Copyright © 2019. Published by Elsevier Inc.)

- Abstract
Objective: In the past decade, prevalence of obesity in the United States have been soaring at a disparaging rate. Previous spine studies have associated obesity with inferior surgical outcomes, increased complication and 30-day readmission rates, and worsening patient-reported outcomes. However, there is a paucity of data identifying whether the impact of obesity is sustained in patients undergoing complex deformity correction involving 7 levels or greater. The aim of this study was to determine whether obesity impacts surgical outcomes, patient-reported pain scores, and 30-day readmission rates after complex spinal fusions ≥7 levels., Methods: The medical records of 112 adult patients (≥18 years old) with spine deformity undergoing elective, primary complex spinal fusion (≥7 levels) for deformity correction at a major academic institution from 2010 to 2015 were reviewed. Preoperative body mass index greater than or equal to 30 kg/m
2 was classified as obese. Patient demographics, comorbidities, and intraoperative and postoperative complication rates were collected for each patient. Inpatient patient-reported pain scores and ambulatory status also were collected. The primary outcomes of this study were surgical outcomes, patient-reported pain scores, and 30-day readmission rates., Results: Of the 112 patients, 33 (29.5%) were obese (obese: n = 33 vs. non-obese: n = 79). Patient demographics and comorbidities were similar between both cohorts, including age, sex, diabetes, hypertension, and home narcotic use. The median number of fusion levels operated, length of surgery, estimated blood loss, transfusion, and complication rates were similar between both cohorts. Moreover, the postoperative complication profiles between the cohorts also were similar, with a comparable length of hospital stay (obese: 6.5 ± 4.6 days vs. non-obese: 7.0 ± 3.9 days, P = 0.5833) and 30-day readmission rates (obese: 12.1% vs. non-obese: 13.9%, P = 0.7984). Baseline (P = 0.6826), first (P = 0.9691), and last (P = 0.9583) postoperative patient-reported pain scores were similar between cohorts. Analogously, ambulatory status was similar between the cohorts, including days from operating room to ambulation (P = 0.3471) and number of steps on first (P = 0.9173) and last (P = 0.1634) ambulatory day before discharge., Conclusions: Our study suggests that obesity does not significantly affect surgical outcomes, patient-reported pain scores, and 30-day readmission rates after complex spinal surgery requiring ≥7 levels of fusion. Further studies are necessary to corroborate our findings., (Copyright © 2019. Published by Elsevier Inc.)- Published

- Abstract
Background: The use of postoperative cervical collars following cervical fusions is common practice. Its use has been purported to improve fusion rates and outcomes. There is a paucity in the strength of evidence to support its clinical benefit. Our objective is to critically evaluate the published literature to determine the strength of evidence supporting the use of postoperative cervical collar use following cervical fusions., Methods: A systematic review using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (also known as PRISMA) was performed. An online search using Medline and Cochrane Central Register of Controlled Trials databases was used to query prospective and retrospective clinical trials evaluating cervical fusions with or without postoperative collar., Results: The search identified 894 articles in Medline and 65 articles in the Cochrane database. From these articles, 130 were selected based on procedure and collar use. Only 3 studies directly compared between collar use and no collar use. Our analysis of the mean improvement in neck disability index scores and improvement over time intervals did not show a statistically significant difference between collar versus no collar (P = 0.86)., Conclusions: We found no strong evidence to support the use of cervical collars after 1- and 2-level anterior cervical discectomy and fusion procedures, and no studies comparing collar use and no collar use after posterior cervical fusions. Given the cost and likely impact of collar use on driving and the return to work, our study shows that currently there is no proven benefit to routine use of postoperative cervical collar in patients undergoing 1- and 2-level anterior cervical discectomy and fusion for degenerative cervical pathologies., (Copyright © 2019 Elsevier Inc.

- Abstract
Objective: To investigate the impact that chronic obstructive pulmonary disease (COPD) has on postoperative complication rates, ambulation, and hospital length of stay for elderly spinal deformity patients after elective spinal fusion (≥3 levels)., Methods: The medical records of 559 elderly (≥60 years old) spine deformity patients undergoing elective spinal fusion (≥3 levels) at a major academic institution from 2005 to 2015 were reviewed. We identified 60 patients with COPD (10.7%) and 499 patients without COPD (89.3%). Patient demographics, comorbidities, postoperative complications, ambulatory status, and readmission rates were collected. The primary outcomes investigated in this study were complication rates and length of hospital stay., Results: Demographics and comorbidities were similar between groups, with a difference in proportion of smokers (COPD group: 25.0% vs. no COPD group: 9.6%, P = 0.0004). The median number of fusion levels (P = 0.840), operative time (P = 0.842), estimated blood loss (P = 0.336), and incidences of durotomy (P = 0.258) was similar between both cohorts. The COPD cohort experienced a higher rate of postoperative fever (10.0% vs. 3.0%, P = 0.007) and pneumonia (5.0% vs. 0.4%, P = 0.0004), respectively. There was a significant difference in the number of feet walked on the first day of ambulation after surgery (COPD group: 58.6 ± 78.4 vs. no COPD group: 84.0 ± 102.8, P = 0.040). Length of hospital stay was significantly longer in the COPD cohort than the no COPD cohort (7.7 ± 6.4 vs. 6.0 ± 4.0 days, respectively; P = 0.0498)., Conclusions: Our study demonstrates that elderly patients with COPD have increased lengths of stay and higher rates of postoperative pneumonia after spinal fusion. This determination identifies a potentially modifiable risk factor for increased utilization of health care resources., (Copyright © 2018 Elsevier Inc. All rights reserved.)

- Abstract
Background: Risk factors for surgical revision remain important because of additional readmission, anesthesia, and morbidity for the patient and significant cost for health care systems. Although the rate of reoperation (RRO) is well described for traditional open posterior (OP) approaches, the RRO in minimally invasive lateral (MIL) surgery remains poorly characterized. This study compares the RRO in patients undergoing decompressive lumbar spine surgery via MIL versus OP approaches., Methods: Patient demographics and comorbidities were retrospectively collected for 2060 patients undergoing single-stage elective lumbar spinal surgery at multiple institutions. A subset of 1484 patients had long-term data (long-term cohort [LT cohort]). The RRO was compared between approaches through univariate and multivariate analysis., Results: There were 1292 patients (62.7%) who underwent lateral access surgery, whereas 768 patients (37.3%) underwent OP surgery. The MIL cohort was significantly older, had a higher proportion of men, and had more comorbidities than the OP cohort. In the LT cohort, lateral patients were significantly older and had more comorbidities, with a lower body mass index and a lower proportion of men and smokers. Surgical complications between the groups trended to be similar. The MIL cohort had a significantly lower RRO at both 30 days (approximately 57% lower, MIL cohort: 1.01% vs. OP cohort: 2.36%, P = 0.02) and 2 years (approximately 61% lower, MIL cohort: 2.09% vs. OP cohort: 5.37%, P < 0.01) after surgery. On multivariate analysis, surgical approach was the only significant predictor for the RRO at both 30 days (open posterior approach odds ratio [OR], 4.47; 95% confidence interval [CI], 1.33-15.09; P = 0.02) and 2 years (open posterior approach OR, 3.26; 95% CI, 1.26-8.42; P = 0.01)., Conclusions: This study shows that MIL surgical approaches, compared with OP approaches, have a significantly lower RRO after lumbar spine surgery., (Copyright © 2018 Elsevier Inc.

- Abstract
Background: Measures of health care use such as length of hospital stay (LOS) are used as proxies for quality of care after spine surgery. Accordingly, hospitals and health systems are investing considerable resources into the preoperative identification of patients at risk for prolonged LOS. This study aims to investigate the impact of preoperative level on outcomes and LOS after spinal fusion., Methods: The medical records of 204 elderly (≥60 years) male patients undergoing elective spinal fusion (≥3 levels) at a major academic institution from 2005 to 2015 were reviewed. The lower hemoglobin (Hgb) level was designated as <13.5 g/dL. We identified 83 (40.7%) patients with preoperative lower Hgb levels and 121 (59.3%) with normal levels (low Hgb, n = 83; normal Hgb, n = 121). The primary outcomes investigated were complications and LOS., Results: Demographics and comorbidities were similar between both groups, with mean Hgb levels being 12.3 ± 0.9 g/dL and 14.9 ± 1.0 g/dL for the low and normal cohorts, respectively. The lower Hgb cohort experienced higher rates of postoperative delirium (21.7% vs. 5.8%; P = 0.0007), non-wound infections (6.0% vs. 0.0%; P = 0.006), and hematoma formation (3.6% vs. 0.0%; P = 0.035). There was a significant difference in LOS between the cohorts, with the low Hgb cohort experiencing approximately a 2-fold increase (low Hgb, 8.1 ± 5.9 days vs. normal Hgb, 4.8 ± 2.5 days; P < 0.0001). Preoperative Hgb and hematocrit levels negatively correlated with LOS (Hgb, R = -0.388, P < 0.001 and Hct, R = -0.2883, P < 0.001)., Conclusions: Our study shows that elderly male patients with lower preoperative Hgb levels have increased LOS and postoperative delirium after spinal fusion. Moreover, preoperative Hgb levels negatively correlate with LOS., (Copyright © 2018 Elsevier Inc. All rights reserved.)

- Abstract
Objective: Interdisciplinary management of elderly patients requiring spine surgery has been shown to improve short- and long-term outcomes. The aim of this study was to determine whether an interdisciplinary team approach mitigates use of intensive care unit (ICU) resources., Methods: A unique comanagement model for elderly patients undergoing lumbar fusion surgery was implemented at a major academic medical center. The Peri-operative Optimization of Senior Health Program (POSH) was launched with the aim of improving outcomes in elderly patients (>65 years old) undergoing complex lumbar spine surgery. In this model, a geriatrician evaluates elderly patients preoperatively, comanages daily throughout hospital course, and coordinates multidisciplinary rehabilitation, along with the neurosurgical team. We retrospectively reviewed the first 100 cases after the initiation of the POSH protocol and compared them with the immediately preceding 25 cases to assess the rates of ICU transfer and independent predictors of ICU admission., Results: A total of 125 patients undergoing lumbar decompression and fusion surgery were enrolled in this pilot program. Baseline characteristics and intraoperative variables, as well as number of fusion levels and duration of surgery, were similar between both cohorts. There was a significant difference in the use of ICU services (ICU admission rates) between both cohorts, with the non-POSH cohort having a 3-fold increase compared with the POSH cohort (P < 0.0001). In a multivariate analysis, lack of an interdisciplinary comanagement team approach was an independent predictor for ICU transfers in elderly patients undergoing corrective surgery (odds ratio 8.51, 95% confidence interval 2.972-24.37, P < 0.0001)., Conclusions: Our study suggests that an interdisciplinary comanagement model between geriatrics and neurosurgery is independently associated with reduced use of critical care services., (Copyright © 2018 Elsevier Inc.

- Abstract
Objective: To determine whether preoperative chronic kidney disease (CKD) is associated with inferior perioperative outcomes in patients undergoing lumbar arthrodesis., Methods: Medical records of 293 adult (≥18 years old) patients with spine deformity undergoing elective lumbar spine decompression and fusion at a major academic institution from 2006 to 2015 were reviewed. We identified 18 (6.1%) patients with a clinical diagnosis of CKD (CKD group, n = 18; no-CKD group, n = 275). Patient demographics, comorbidities, and intraoperative and postoperative complication rates were collected for each patient. The primary endpoint was incidence of postoperative complications., Results: Patient demographics, including age, sex, and body mass index, and comorbidities were similar between cohorts. The CKD group had a significantly higher prevalence of hypertension, hyperlipidemia, and anemia compared with the no-CKD group. Median number of fusion levels, length of surgery, and estimated blood loss were similar between both cohorts. Postoperative complication profile was significantly different between the cohorts, with the CKD group having a significantly higher proportion of patients transferred to the intensive care unit (52.9% vs. 29.3%, P = 0.04) with episodes of delirium (27.8% vs. 8.4%, P = 0.007), urinary tract infection (27.8% vs. 6.9%, P = 0.0002), and deep vein thrombosis (5.6% vs. 0.4%, P = 0.01). Although not significant, the CKD group had a 2-fold higher rate of 30-day readmissions compared with the no-CKD group (CKD group: 27.8% vs. no-CKD group: 12.7%, P = 0.07)., Conclusions: Our study suggests that patients with CKD may be more likely to develop perioperative complications after lumbar arthrodesis. Future studies are necessary to corroborate our findings., (Copyright © 2017 Elsevier Inc. All rights reserved.)

- Abstract
Background: The aim of this study is to determine whether preoperative scores on a screening measure for cognitive status (the Saint Louis University mental status examination), were associated with discharge to a location other than home in older patients undergoing surgery for deformity., Methods: Older patients (≥65 years) undergoing a planned elective spinal surgery for correction of adult degenerative scoliosis were enrolled in this study. Preoperative baseline cognition was assessed using the validated Saint Louis University mental status (SLUMS) test. SLUMS is 11 questions with a maximum of 30 points. Mild cognitive impairment was defined as a SLUMS score of 21-26 points, and severe cognitive impairment as a SLUMS score of 20 points or greater. Normal cognition was defined as a SLUMS score of 27 points or more. Postoperative length of stay and discharge location were recorded on all patients., Results: Eighty-two subjects were included, with mean ± standard deviation age of 73.26 ± 6.08 years; 51% of patients were discharged to a facility (skilled nursing or acute rehabilitation). After adjustment for demographic variables, comorbidities, and baseline cognitive impairment, patients with preoperative cognitive impairment were 4-fold more likely to be discharged to a facility (skilled nursing or acute rehabilitation) compared with patients with normal cognitive status (odds ratio [OR], 3.93). In addition, patients who were not ambulatory before surgery were also more likely to be discharged to a facility (OR, 7.14)., Conclusions: In geriatric patients undergoing surgery for deformity correction, cognitive screening before surgery can identify patients with impaired cognitive status who are less likely than those with normal cognitive status to return home after surgery., (Copyright © 2017 Elsevier Inc.

- Abstract
Background: Smoking status has been shown to affect postoperative outcomes after surgery. The aim of this study was to determine whether patients' smoking status impacts 30-day complication and readmission rates after elective complex spinal fusion (≥3 levels)., Methods: The medical records of 839 adult spinal deformity patients undergoing elective complex spinal fusion (≥3 levels) at a major academic institution from 2005 to 2015 were reviewed. We identified 124 (14.8%) smokers and 715 (85.2%) nonsmokers. Patient demographics, comorbidities, intraoperative and postoperative complications, and 30-day readmission rates were collected for each patient. The primary outcome investigated in this study was the rate of 30-day postoperative complication and readmission rates., Results: Patient demographics and comorbidities were similar between both groups, including age, sex, and body mass index. Median [interquartile] number of fusion levels and operative time were similar between the cohorts (smoker: 5 [4-7] vs. nonsmoker: 5 [4-8], P = 0.58) and (smoker: 309.6 ± 157.9 minutes vs. nonsmoker: 287.5 ± 131.7 minutes, P = 0.16), respectively. Both cohorts had similar postoperative complication rates and lengths of hospital stay. There was no significant difference in 30-day readmission between the cohorts (smoker: 12.9% vs. nonsmoker: 10.8%, P = 0.48). There were no observed differences in 30-day complication rates, including pain (P = 0.46), UTI (P = 0.54), hardware failure (P = 0.36), wound dehiscence (P = 0.29), and wound drainage (P = 0.86). Smokers had greater rates of 30-day cellulitis (smoker: 1.6% vs. nonsmoker: 0.3%, P = 0.05) and DVT (smoker: 0.8% vs. nonsmoker: 0.0%, P = 0.02)., Conclusions: Our study suggests that smoking does not significantly affect 30-day readmission rates after complex spinal surgery requiring ≥3 levels of fusion. Further studies are necessary to corroborate our findings., (Copyright © 2017 Elsevier Inc. All rights reserved.)

- Abstract
Background: The aim of this study was to assess whether the Koenig Depression Scale (KDS) can identify depressed elderly patients undergoing elective spine surgery for deformity at risk for inferior postoperative outcomes including complication rates, ambulation ability, and patient-reported outcomes., Methods: The medical records of 92 elderly patients (≥65 years) undergoing a planned elective spinal surgery for correction of adult degenerative scoliosis were reviewed for this study. Preoperative baseline depression was assessed using the validated KDS that was administered by a board-certified geriatrician. KDS is made up of 11 questions with a maximum of 11 points (No-Depression = KDS <4, Depression = KDS ≥4). The primary outcomes of this study were complication rates, duration of hospital stay, ambulation ability, and follow-up visual analog scale (VAS) scores at 6 weeks, 3 months, and 6 months after hospital discharge., Results: Of the 92 patients, 20 of them (21.7%) were found to have a KDS ≥4. Baseline demographics and comorbidities were similar between both cohorts. Intraoperative variables and complications were similar between both cohorts. There were no significant differences in postoperative complications including length of hospital stay. There was no significant difference in ambulation abilities including preoperative gait speed (P = 0.38), days from operation to ambulation (P = 0.86), steps on first day of ambulation (P = 0.57), and steps before hospital discharge (P = 0.35). There was no significant difference between the cohorts in VAS scores at baseline (P = 0.19), 6 weeks (P = 0.91), 3 months (P = 0.58), and 6 months (P = 0.97) after hospital discharge., Conclusions: Our study found no difference in complication rates, ambulation abilities, and follow-up VAS scores between patients with and without depression using preoperative KDS., (Copyright © 2017 Elsevier Inc.

- Abstract
Background: There is a paucity of data determining the impact that gender disparities have on spine outcomes, particularly perception of health and satisfaction. The aim of this study was to determine whether there is a difference in 3-month and 1-year patient-reported outcomes and satisfaction after elective lumbar spine surgery., Methods: This was a retrospectively analyzed study from a maintained prospective database of 384 patients who underwent elective lumbar spine surgery. Patients were categorized by gender (men, n = 199; women, n = 185). Patient-reported outcome instruments (Oswestry disability index, visual analogue scale-back pain/leg pain, EuroQol visual analogue scale, and EuroQol 5 dimensions questionnaire) were completed before surgery, then at 3 and 12 months after surgery along with patient satisfaction measures., Results: Baseline patient demographics, comorbidities, and operative variables were similar between both cohorts. The female cohort had a slightly longer hospital stay than male cohort (P = 0.007). Baseline patient-reported outcome measures were different between both cohorts, with female patients having more Oswestry disability index (23.8 vs. 20.4; P ≤ 0.0001) and visual analogue scale-back pain (7.2 vs. 6.2; P = 0.0004), and a lower EuroQol 5 dimensions questionnaire (0.34 vs. 0.49; P = 0.0001) compared with the male cohort. At 1-year follow-up, the male cohort had a significantly more mean change in visual analogue scale-leg pain (-3.9 vs. -2.8; P = 0.04) and trended to have more mean change in visual analogue scale-back pain (-3.4 vs. -2.5; P = 0.06) and EuroQol visual analogue scale (8.6 vs. 3.4; P = 0.054) scores compared with the female cohort. At 1-year a significantly more portion in the male cohort found that surgery met their expectations compared with the female cohort (65.0% vs. 49.5%; P = 0.02)., Conclusions: Our study suggests that there may be differences in perception of health, pain, and disability between men and women at baseline, short-term and long-term follow-up that may influence overall patient satisfaction., (Copyright © 2017 Elsevier Inc.

- Abstract
Objective: Although extreme lateral interbody fusion (XLIF) largely provides successful indirect decompression, some patients have recurrent same-level pain and functional disability. Identifying risk factors for this failure would facilitate better patient selection and improve outcomes. The aim of this study is to identify preoperative radiographic risk factors for failure of XLIF., Methods: Patients undergoing XLIF were prospectively enrolled by 3 surgeons at 3 separate institutions. Radiographic variables measured included (1) anterior and posterior disc height, (2) foramen height and area, (3) central canal diameter, (4) central canal area, (5) right and left subarticular diameters, (6) facet arthropathy grade, and (7) presence of bony lateral recess stenosis. Patients failed indirect decompression if Oswestry Disability Index (ODI) scores did not improve by 20 points or revision surgery was required within 6 months postoperatively. Univariate and multivariate analyses were performed to identify radiographic predictors of failure of indirect decompression., Results: Of the 45 patients (age 65.6 ± 10.5 years; 14 male) involving 101 spinal levels included in this study, 13 (29%) failed indirect decompression. From univariate analysis, these patients had significantly smaller central canal diameter, foraminal height, and disc height (P < 0.05). In multivariate analysis of these parameters and those trending toward significance, bony lateral recess stenosis was the only significant independent predictor for failure of indirect decompression (coefficient, 0.55 [0.24-0.85]; P < 0.001)., Conclusions: Bony lateral recess stenosis is an independent predictor for failure to achieve adequate spinal decompression via XLIF and thus may benefit from undergoing direct decompression., (Copyright © 2017 Elsevier Inc.

- Abstract
Objective: Recent studies have reported that decompression with fusion leads to superior outcomes in correction of spinal deformity. The aim of this study was to determine if there is a difference in intraoperative and 30-day postoperative complication rates in patients undergoing spinal fusion with and without decompression., Methods: Medical records of 874 adult (≥18 years old) patients with spinal deformity undergoing elective spinal fusion at a major academic institution from 2005 to 2015 were reviewed; 374 (42.8%) patients underwent laminectomy in addition to spinal fusion. The primary outcome investigated was the rate of intraoperative and 30-day complications., Results: Patient demographics and comorbidities were similar between groups. The laminectomy cohort had significantly higher estimated blood loss (P < 0.0001), incidence of allogeneic blood transfusions (P = 0.0001), and rate of intraoperative durotomies (laminectomy cohort 10.4% vs. no-laminectomy cohort 3.1%; P < 0.0001). The laminectomy cohort had a significantly higher proportion of patients in the intensive care unit (28.6% vs. 17.7%; P < 0.001). There was no significant difference in 30-day readmission rate between cohorts (laminectomy cohort 13.0% vs. no-laminectomy cohort 9.8%; P = 0.13). Within 30 days after initial discharge, the laminectomy cohort had significantly higher rates of altered mental status (3.2% vs. 1.2%; P = 0.05), urinary tract infection (4.3% vs. 1.4%; P = 0.009), wound drainage (7.2% vs. 3.1%; P = 0.007), and instrumentation failure (1.1% vs. 0.0%; P = 0.03)., Conclusions: Patients undergoing spinal fusion with laminectomy may have higher complication rates than patients undergoing spinal fusion alone., (Copyright © 2017 Elsevier Inc.

- Abstract
Objective: The aim of this study is to determine if there are differences in 30-day postoperative complication and readmission rates between patients with spinal deformity undergoing complex spinal fusion with and without intraoperative monitoring (IOM)., Methods: The medical records of 643 adult patients with spine deformity undergoing elective complex spinal fusion (≥4 levels) at a major academic institution from 2005 to 2015 were reviewed. We identified 122 cases (19%) that involved IOM including electromyography, somatosensory evoked potential, and/or transcranial motor evoked potential and 521 (81%) that did not (IOM, n = 122; no-IOM, n = 521). The primary outcome investigated was the rate of 30-day postoperative complications and readmission., Results: Patient demographics and comorbidities were similar between both groups, including age, gender, body mass index, and smoking status. IOM cases had significantly increased operative time (IOM, 360.9 ± 153.8 minutes vs. no-IOM, 290.3 ± 127.1 minutes; P < 0.0001), with no differences in the incidences of spinal cord injury, nerve injury, and durotomy. Both cohorts had similar postoperative complications and length of hospital stay, with the no-IOM cohort having a greater incidence of intensive care unit transfer (no-IOM, 27.1% vs. IOM, 16.1%, P = 0.015). There was no significant difference in 30-day readmission between the cohorts (IOM, 8.2% vs. no-IOM, 12.3%; P = 0.27) or differences in sensorimotor deficits. Although the overall 30-day complication rate trended to be higher in the no-IOM cohort, these factors were not attributed to IOM use., Conclusions: Our study suggests that the use of IOM may not have a significant impact on overall surgical outcomes and 30-day readmission rates., (Copyright © 2017 Elsevier Inc.

- Abstract
Background: Altered mental status (AMS) has been associated with inferior surgical outcomes. The factors leading to AMS after spine surgery are unknown. The aim of this study is to determine the risk factors and independent predictors of 30-day readmission for AMS in patients with spine deformity after undergoing elective spine surgery., Methods: The medical records of 1090 adult (≥18 years old) patients with spine deformity undergoing elective spine surgery at a major academic institution from 2005 to 2015 were reviewed. We identified 18 patients (1.65%) who had AMS as the primary driver for 30-day readmission after surgery. Patient demographics, comorbidities, and intraoperative and postoperative complication rates were collected for each patient. The primary outcome investigated in this study was risk factors associated with 30-day readmission for AMS., Results: Patient demographics and comorbidities were similar between both groups, with the AMS cohort being significantly older than the no-AMS cohort (70.11 vs. 61.93; P = 0.003). There were no significant differences in intraoperative variables and complication rates within the cohorts. The AMS cohort had a significantly higher proportion of patients transferred to the intensive care unit (AMS, 61.11% vs. no-AMS, 19.76%; P = 0.0002) and rate of pulmonary embolism (AMS, 11.11 vs. no-AMS, 0.93; P = 0.02) after surgery. Other postoperative complication rates were similar between the cohorts. In a multivariate stepwise regression analysis, age (P = 0.013) and ICU transfer (P = 0.0002) were independent predictors of 30-day readmission for AMS., Conclusions: Our study suggests that increasing age and intensice care unit transfer are independent predictors of 30-day readmission for AMS after spine surgery in patients with spine deformity., (Copyright © 2017 Elsevier Inc.

Objective: Racial disparities have been shown to affect surgical outcomes. However, the effect of race on complex spinal fusion outcomes remains understudied. The aim of this study is to determine if patient race affects 30-day complication rates after elective complex spinal fusion (≥5 levels)., Methods: The medical records of 490 adult patients with spinal deformity undergoing elective complex spinal fusion (≥5 levels) at a major academic institution from 2005 to 2015 were reviewed. We identified 52 black patients (11.7%) and 438 white patients (88.3%). Patient demographics, comorbidities, and intraoperative and 30-day postoperative complication and readmission rates were collected. The primary outcome investigated in this study was the rate of 30-day postoperative complications., Results: Patient demographics and comorbidities were similar between both groups, including age, gender, and body mass index. Median (interquartile range) number of fusion levels and operative time were similar between the cohorts (black, 6.5 [5-9] vs. white, 7 [5-9]; P = 0.55; and black, 307.3 ± 120.2 minutes vs. white, 321.3 ± 135.3 minutes; P = 0.45, respectively). Both cohorts had similar postoperative complications and lengths of hospital stay (black, 7.2 ± 5.4 days vs. white: 6.5 ± 4.9; P = 0.37). There was no significant difference in 30-day readmission between the cohorts (black, 9.6% vs. white, 12.8%; P = 0.66). There were no observed differences in 30-day complication rates, including: pain (P = 0.74), urinary tract infection (P = 0.68), hardware failure (P = 0.36), wound dehiscence (P = 0.29), and drainage (P = 0.86)., Conclusions: Our study suggests that there is no difference between races in 30-day complication and readmission rates after complex spinal surgery requiring ≥5 levels of fusion., (Copyright © 2016 Elsevier Inc.

- Abstract
Background: Spinal deformities that require ≥5 fusion levels are difficult and challenging for both the surgeon and patient. Corrections of moderate to severe deformities have been shown to improve patient-reported outcomes (PROs), and provide patients with a better quality of life. Self-image is an important PRO because it sheds insight into the patient's perception of health, as well as serving as a proxy of satisfaction for patients with spine deformity undergoing corrective surgery. However, with an aging population, the impact of age on long-term change in self-image is unknown. The aim of this study is to determine the effects of age on self-image 5 years after undergoing an elective complex spinal fusion (≥5 levels)., Methods: This was a retrospective analysis of prospectively collected data of 55 adult patients (≥18 years old) undergoing ≥5 levels of spinal fusion to the sacrum with iliac fixation from January 2002 to December 2008. Patients were grouped by age: young (<60 years old) and older (≥60 years old). Patient demographics, comorbidities, preoperative variables (sagittal and Cobb angles) and postoperative complication rates were collected. All patients had prospectively collected outcome measures and a minimum of 5 years follow-up. PRO instrument SRS-22r (function, self-image, mental health, and pain) was completed before surgery then at follow-up (at least 5 years after surgery). The primary outcome investigated in this study was the change in self-image after surgery., Results: Baseline characteristics and preoperative variables were similar in both cohorts. There were no significant differences in intraoperative variables, including the mean ± standard deviation number of fusion levels between the cohorts (young, 11.2 ±4.3 vs. older, 12.1 ± 4.0; P = 0.42). Complication rates were similar between the cohorts, with no significant differences in the types of complications (young, 29.63% vs. older, 25.0%; P = 0.77). There were no significant differences in preoperative and follow-up PROs between the cohorts. The mean ± standard deviation preoperative and follow-up self-image scores were (young, 2.35±0.58 vs. older, 2.68 ± 0.64; P = 0.51) and (young, 3.82 ± 0.63 vs. older, 3.51 ± 0.94), respectively. There were no significant differences in the change of function, mental health, or pain between the cohorts. However, the younger cohort experienced a significantly greater overall change in self-image than did the older cohort (young, 1.49 ± 0.87 vs. older, 0.70±1.14; P = 0.01)., Conclusions: Our study suggests that age significantly affects the perception of self-image after deformity correction surgery; with younger patients reporting a greater change from baseline in self-image after surgery. Further studies are necessary to corroborate our observed findings., (Copyright © 2016 Elsevier Inc. All rights reserved.)

- Abstract
Background: Early readmission after spine surgery is being used as a proxy for quality of care. One-fifth of patients are rehospitalized within 30 days after spine surgery, and more than one-third within 90 days; however, there is a paucity of data about the cause of early readmissions in elderly patients after elective spine surgery., Methods: A total of 500 elderly patients (>65 years old) undergoing elective spine surgery at a major academic hospital were included in the study. We identified all unplanned readmissions within 30 days of discharge. Unplanned readmissions were defined to have occurred as a result of either a surgical or a nonsurgical complication. Patient records were reviewed to determine the cause of readmission and the length of hospital stay., Results: A total of 50 (10%) unplanned early readmissions were identified. The mean ± SD age was 72.54 ± 5.84 years. The mean ± SD number of days from discharge to readmission was 11.02 ± 7.25 days, and the average length of hospital stay for the readmissions was 7.7 days. The majority of patients that were readmitted presented to the emergency department from home (46%), whereas 38% were readmitted from a skilled nursing facility. The most common causes for readmission were infection or a concern for infection (42%) and pain (14%), with 32% of readmissions requiring a return to the operating room., Conclusion: Our study suggests that in elderly patients undergoing elective spine surgery, infection or a concern for infection, pain, and altered mental status were the most common primary reasons for unplanned readmission., (Copyright © 2016 Elsevier Inc.

- Abstract
Objective: The use of intraoperative steroids and their effects are relatively unknown and remain controversial. The aim of this study was to determine the effects of intraoperative steroid use on postoperative complications and length of hospital stay after spine surgery., Methods: Medical records of 1200 adult patients undergoing spine surgery at Duke University Medical Center during the period 2008-2010 were retrospectively reviewed; 495 (41.25%) patients were administered intraoperative steroids, and 705 (58.75%) patients were not administered intraoperative steroids. Patient demographics, comorbidities, and postoperative complication rates were collected. The primary outcomes investigated were postoperative complications, specifically length of hospital stay and infection rates., Results: Patient demographics were similar between both cohorts. Comorbidities were also similar, with the intraoperative steroid use cohort having a higher number of patients with long-term steroid use than the no intraoperative steroid use cohort (6.95% [no steroids] vs. 13.74% [steroid use], P < 0.001). Operative variables, including length of operation and median number of fusion levels operated, were also similar between the 2 groups. Lumbar spine was the most common surgical location. Patients who were administered intraoperative steroids had a shorter length of hospital stay by an average of 1 day (6.06 days ± 6.76 [no steroids] vs. 5.04 days ± 4.86 [steroid use], P = 0.0025), lower rates of urinary tract infections (10.37% [no steroids] vs. 6.88% [steroid use], P = 0.040), and lower rates of other infections that were not deep or superficial surgical site infections (9.22% [no steroids] vs. 6.06% [steroid use], P = 0.0460)., Conclusions: Patients who receive intraoperative steroids have shorter hospital stays and lower infection rates after spine surgery., (Copyright © 2016 Elsevier Inc.

- Abstract
Background: Prompt decompression in clinically significant cervical stenosis is important in the prevention of neurological sequelae. Disparities exist along the continuum on spine care, with black patients receiving less surgery and experiencing worse postoperative outcomes. The aim of this study was to assess whether black race was an independent predictor for a prolonged time to diagnosis and treatment., Methods: The medical records of 133 patients undergoing elective anterior cervical discectomy and fusion surgery at a major academic medical center between 2010 and 2012 were reviewed. All patients had prospectively collected patient-reported outcomes measures including visual analogue scale (VAS) of pain. Data on patient demographics, comorbidities, and postoperative complication rates were retrospectively collected. Multivariate analysis was performed on variables that trended with delay in diagnosis and treatment on univariate analysis to determine independent predictors of delay in diagnosis and treatment., Results: Patient demographics of the cohort included 45.87% male, 80.30% white, 71.97% married, 53.72% employed, 18.8% with a history of depression, and 19.55% with anxiety. The mean ± standard deviation age was 54.02 ± 11.74 years and baseline VAS-neck pain was 4.87 ± 3.19. In a multivariate analysis, race was the only statistically significant variable (P = 0.0212) to predict increased duration of preoperative pain before treatment. Other variables in the model included depression, anxiety, age, gender, employment status, marital status, body mass index, and baseline VAS-neck pain score., Conclusions: Our study demonstrates that race is an independent risk factor for a temporal delay in diagnosis and treatment of symptomatic cervical stenosis., (Copyright © 2016 Elsevier Inc.

- Abstract
Background: Hospital readmission within 30 days of index surgery is receiving increased scrutiny as an indicator of poor quality of care. Reducing readmissions achieves the dual benefit of improving quality and reducing costs. With the growing prevalence of obesity, understanding its impact on 30-day unplanned readmissions and patients' perception of health status is important for appropriate risk stratification of patients. The aim of this study was to determine if obesity is an independent risk factor for unplanned 30-day readmissions after elective spine surgery., Methods: The medical records of 500 patients (nonobese, n = 281; obese, n = 219) undergoing elective spine surgery at a major academic medical center were reviewed. Preoperative body mass index (BMI) was measured on all patients. BMI that was ≥30 kg/m
2 was classified as obese. Patient demographics, comorbidities, and postoperative complication rates were collected. The primary outcome investigated was unplanned all-cause 30-day hospital readmission. The association between preoperative obesity and 30-day readmission rate was assessed via multivariate logistic regression analysis., Results: Baseline characteristics and operative variables and complication profiles were similar between both cohorts. Overall, 8.6% of patients were readmitted within 30 days of discharge; obese patients experienced a 2-fold increase in 30-day readmission rates (obese 12.33% vs. nonobese 5.69%, P = 0.01). In a multivariate logistic regression analysis, preoperative obesity (BMI ≥30 kg/m2 ) was found to be an independent predictor of 30-day readmission after elective spine surgery (P = 0.001)., Conclusions: Preoperative obesity is an independent risk factor for readmission within 30 days of discharge after elective spine surgery. In a cost-conscious health care climate, preoperative BMI can identify patients at risk for early unplanned hospital readmission., (Copyright © 2016 Elsevier Inc. All rights reserved.)- Published

- Abstract
Background: There is a growing understanding of the prevalence and impact of affective disorders on perception of health status in patients undergoing elective spine surgery. However, the role of these disorders in early readmission is unclear. The aim of this study is to investigate the influence of psychiatric comorbidities on 30-day all-cause readmissions after elective spine surgery., Methods: The medical records of 400 patients undergoing elective spine surgery at a major academic medical center were reviewed, of which 107 patients had comprehensive 1- and 2-year patient-reported outcomes data. We identified all unplanned readmissions within 30 days of discharge. The prevalence of affective disorders, such as depression and anxiety, were also assessed. All-cause readmissions within 30 days of discharge was the primary outcome variable., Results: Baseline characteristics were similar between groups. Approximately 6% of patients in this study were readmitted within 30 days of discharge. The rate of readmission was 3-fold more for individuals with a psychiatric comorbidity compared with those without a psychiatric comorbidity (10.34% vs. 3.84%, P = 0.03). In a univariate analysis, race, body mass index, gender, patient age, smoking, diabetes, and fusion levels were associated with increased 30-day readmission rates. However, in a multivariate logistic regression model, depression was an independent predictor of readmission within 30 days of discharge. In addition, there was no significant difference in baseline, 1- and 2-year patient-reported outcomes measures between groups., Conclusions: Our study suggests that psychologic disorders, like depression and anxiety, are independently associated with higher all-cause 30-day readmission rates after elective spine surgery., (Copyright © 2016 Elsevier Inc.

- Abstract
Background: Deep vein thrombosis (DVT) is a morbid postsurgical complication. Identifying the perioperative DVT risk profile will improve surgeons' ability to assess patients for surgical candidacy. In addition, these data will help to identify patients who would benefit from DVT chemoprophylaxis., Methods: We evaluated all medical records for 1346 consecutive patients who underwent spinal surgery at Duke University for incidence of DVT within 30 days of surgery and documented all demographic, preoperative, operative, and postoperative variables. DVT treatment and long-term outcomes were also documented. Associations between postoperative DVT and individual risk factors in all patients were determined using adjusted logistic regression analysis. Patients were stratified into emergent and elective groups and a similar analysis was performed., Results: Overall, 15 patients (1.1%) had a DVT in the 30 days after surgery, 7 patients (0.6%) after elective surgery and 8 patients (4.2%) after emergent surgery (P = 0.03). Overall, multivariate logistic regression determined that previous DVT, postoperative urinary tract infection, and creatinine level >2.0 mg/dL were identified as positive predictors. When stratified by emergent surgery, we found packed red blood cell transfusion, surgical blood loss >2.0 L, and deep surgical site infection to be independently associated with increased risk of postoperative DVT. When stratified by elective surgery, we found that coronary artery disease and atrial fibrillation were associated with increased risk of DVT. No patients died in the 30-day perioperative period and 5 (33.3%) patients died within 1 year., Conclusions: This study identifies patient factors predictive of postoperative DVT. Postoperative DVT prophylaxis may be warranted for patients undergoing emergent spine surgery because these patients have significantly higher risk of developing postoperative DVT., (Published by Elsevier Inc.)
