Abstract
STUDY DESIGN National population-based cohort study. OBJECTIVE The overall complication rate for patients with athetoid cerebral palsy (CP) undergoing cervical surgery is significantly higher than that of patients without CP. The study was conducted to compare the reoperation and complication rates of anterior fusion, posterior fusion, combined fusion, and laminoplasty for degenerative cervical myelopathy/radiculopathy in patients with athetoid cerebral palsy. METHODS The Korean Health Insurance Review and Assessment Service national database was used for analysis. Data from patients diagnosed with athetoid CP who underwent cervical spine operations for degenerative causes between 2002 and 2020 were reviewed. Patients were categorized into four groups for comparison: anterior fusion, posterior fusion, combined fusion, and laminoplasty. RESULTS A total of 672 patients were included in the study. The overall revision rate was 21.0% (141/672). The revision rate was highest in the anterior fusion group (42.7%). The revision rates of combined fusion (11.1%; hazard ratio [HR], .335; P = .002), posterior fusion (13.8%; HR, .533; P = .030) were significantly lower than that of anterior fusion. Revision rate of laminoplasty (13.1%; HR, .541; P = .240) was also lower than anterior fusion although the result did not demonstrate statistical significance. CONCLUSION Anterior fusion presented the highest reoperation risk after cervical spine surgery reaching 42.7% in patients with athetoid CP. Therefore, anterior-only fusion in patients with athetoid CP should be avoided or reserved for strictly selected patients. Combined fusion, with the lowest revision risk at 11.1%, could be safely applied to patients with athetoid CP.

Abstract
Introduction Degenerative cervical myelopathy (DCM) is a form of chronic spinal cord injury, with a natural history of potential for progression over time. Whilst driven by mechanical stress on the spinal cord from degenerative and congenital pathology, the neurological phenotype of DCM is likely to be modified by multiple systemic factors. The role of metabolic factors is therefore of interest, particularly given that ischaemia is considered a key pathological mechanism of spinal cord injury. The objective was therefore to synthesise current evidence on the effect of metabolism on DCM susceptibility, severity, and surgical outcomes. Methods A systematic review in MEDLINE and Embase was conducted following PRISMA guidelines. Full-text papers in English, with a focus on DCM and metabolism, including diabetes, cardiovascular disease, anaemia, and lipid profile, were eligible for inclusion. Risk of methodological bias was assessed using the Joanna Briggs Institute (JBI) critical assessment tools. Quality assessments were performed using the GRADE assessment tool. Patient demographics, metabolic factors and the relationships between metabolism and spinal cord disease, spinal column disease and post-operative outcomes were assessed. Results In total, 8,523 papers were identified, of which 57 met criteria for inclusion in the final analysis. A total of 91% (52/57) of included papers assessed the effects of diabetes in relation to DCM, of which 85% (44/52) reported an association with poor surgical outcomes; 42% of papers (24/57) discussed the association between cardiovascular health and DCM, of which 88% (21/24) reported a significant association. Overall, DCM patients with diabetes or cardiovascular disease experienced greater perioperative morbidity and poorer neurological recovery. They were also more likely to have comorbidities such as obesity and hyperlipidaemia. Conclusion Metabolic factors appear to be associated with surgical outcomes in DCM. However, evidence for a more specific role in DCM susceptibility and severity is uncertain. The pathophysiology and natural history of DCM are critical research priorities; the role of metabolism is therefore a key area for future research focus.

Abstract
STUDY DESIGN Retrospective analysis. OBJECTIVE To assess perioperative complication rates and readmission rates after ACDF in a patient population of advanced age. SUMMARY OF BACKGROUND DATA Readmission rates after ACDF are important markers of surgical quality and, with recent shifts in reimbursement schedules, they are rapidly gaining weight in the determination of surgeon and hospital reimbursement. METHODS Patients 18 years of age and older who underwent elective single-level ACDF were identified in the National Readmissions Database (NRD) and stratified into 4 cohorts: 18-39 ("young"), 40-64 ("middle"), 65-74 ("senior"), and 75+ ("elderly") years of age. For each cohort, the perioperative complications, frequency of those complications, and number of patients with at least 1 readmission within 30 and 90 days of discharge were analyzed. χ 2 tests were used to calculate likelihood of complications and readmissions. RESULTS There were 1174 "elderly" patients in 2016, 1072 in 2017, and 1010 in 2018 who underwent ACDF. Their rate of any complication was 8.95%, 11.00%, and 13.47%, respectively ( P <0.0001), with dysphagia and acute posthemorrhagic anemia being the most common across all 3 years. They experienced complications at a greater frequency than their younger counterparts (15.80%, P <0.0001; 16.98%, P <0.0001; 21.68%, P <0.0001). They also required 30-day and 90-day readmission more frequently ( P <0.0001). CONCLUSION It has been well-established that advanced patient age brings greater risk of perioperative complications in ACDF surgery. What remains unsettled is the characterization of this age-complication relationship within specific age cohorts and how these complications inform patient hospital course. Our study provides an updated analysis of age-specific complications and readmission rates in ACDF patients. Orthopedic surgeons may account for the rise in complication and readmission rates in this population with the corresponding reduction in length and stay and consider this relationship before discharging elderly ACDF patients.

Abstract
PURPOSE With an increasing number of anterior cervical discectomy and fusion (ACDF) being conducted for degenerative cervical disc disease, there is a rising interest in the related quality of management and healthcare costs. Unplanned readmission after ACDF affects both the quality of management and medical expenses. This meta-analysis was performed to evaluate the risk factors of unplanned readmission after ACDF to improve the quality of management and prevent increase in healthcare costs. MATERIALS AND METHODS We searched the databases of PubMed, EMBASE, Web of Science, and Cochrane Library to identify eligible studies using the searching terms, "readmission" and "ACDF." A total of 10 studies were included. RESULTS Among the demographic risk factors, older age [weighted mean difference (WMD), 3.93; 95% confidence interval (CI), 2.30-5.56; p<0.001], male [odds ratio (OR), 1.23; 95% CI, 1.10-1.36; p<0.001], and private insurance (OR, 0.34; 95% CI, 0.17-0.69; p<0.001) were significantly associated with unplanned readmission. Among patient characteristics, hypertension (HTN) (OR, 2.14; 95% CI, 1.41-3.25; p<0.001), diabetes mellitus (DM) (OR, 1.59; 95% CI, 1.20-2.11; p=0.001), coronary artery disease (CAD) (OR, 2.87; 95% CI, 2.13-3.86; p<0.001), American Society of Anesthesiologists (ASA) physical status grade >2 (OR, 2.13; 95% CI, 1.68-2.72; p<0.001), and anxiety and depression (OR, 1.39; 95% CI, 1.29-1.51; p<0.001) were significantly associated with unplanned readmission. Among the perioperative factors, pulmonary complications (OR, 22.52; 95% CI, 7.21-70.41; p<0.001) was significantly associated with unplanned readmission. CONCLUSION Male, older age, HTN, DM, CAD, ASA grade >2, anxiety and depression, pulmonary complications were significantly associated with an increased occurrence of unplanned readmission after ACDF.

[PMID: 34733105 PMCID: PMC8558601 DOI: 10.1177/11786388211054664] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2021] [Accepted: 10/03/2021] [Indexed: 01/03/2023] Open
Abstract
Introduction Degenerative cervical myelopathy (DCM) is the commonest cause of adult spinal cord impairment worldwide, encompassing chronic compression of the spinal cord, neurological disability and diminished quality of life. Evidence on the contribution of environmental factors is sparse; in particular, the role of nutrition in DCM is unknown. The objective of this review was to assess the effect of nutrition on DCM susceptibility, severity and surgical outcome. Methods A systematic review in MEDLINE and Embase was conducted following PRISMA guidelines. Full-text papers in English papers, focussing on cervical myelopathy and nutrition, published before January 2020 were considered eligible. Quality assessments were performed using the GRADE assessment tool. Patient demographics, nutritional factor and DCM outcomes measures were recorded. Relationships between nutritional factors, interventions and disease prognosis were assessed. Results In total, 5835 papers were identified of which 44 were included in the final analysis. DCM patients with pathological weight pre-operatively were more likely to see poorer improvements post-surgically. These patients experienced poorer physical and mental health improvements from surgery compared to normal weight patients and were more likely to suffer from post-operative complications such as infection, DVT, PE and hospital readmissions. Two trials reporting benefits of nutritional supplements were identified, with 1 suggesting Cerebrolysin to be significant in functional improvement. An unbalanced diet, history of alcohol abuse and malnourishment were associated with poorer post-operative outcome. Conclusion Although the overall strength of recommendation is low, current evidence suggests nutrition may have a significant role in optimising surgical outcome in DCM patients. Although it may have a role in onset and severity of DCM, this is a preliminary suggestion. Further work needs to be done on how nutrition is defined and measured, however, the beneficial results from studies with nutritional interventions suggest nutrition could be a treatment target in DCM.

Abstract
OBJECTIVE To elucidate risk factors for 90-day readmission in anterior cervical discectomy and fusion (ACDF) for small, medium, and large hospitals. To assess differences in length of stay, charges, and complication rates across hospitals of different size. METHODS A retrospective analysis was performed using elective, single-level ACDF data from 2016 to 2018 in the Healthcare Cost and Utilization Project Nationwide Readmissions Database. Elective single-level ACDF cases were stratified into 3 groups by hospital bed size (small, medium, and large). All-cause complication rates, mean charges, length of stay, and 90-day readmission rates were compared across hospital size. Frequencies of specific comorbidities were compared between readmitted and nonreadmitted patients for each hospital size. Comorbidities significant on univariate analysis were evaluated as independent risk factors for 90-day readmission for each hospital size using multivariate regression. RESULTS The overall 90-day readmission rate was 6.43% in 36,794 patients, and the rates for small, medium, and large hospitals were 6.25%, 6.28%, and 6.56%, respectively (P = 0.537). Length of stay increased significantly with hospital size (P < 0.001), and small hospitals had the lowest charges (P < 0.001). Although different independent predictors of 90-day readmission were identified for each hospital size, cardiac arrhythmia, chronic pulmonary disease, neurologic disorders, and rheumatic disease were identified as risk factors for hospitals of all sizes. CONCLUSIONS Hospital size is a determining factor for charges and length of stay associated with elective single-level ACDF. Variation in risk factors for readmission exists across hospital size in context of similar 90-day readmission rates.

Abstract
BACKGROUND Posterior cervical decompression and fusion (PCF) is a common procedure used to treat various cervical spine pathologies, but the 90-d outcomes following PCF surgery continue to be incompletely defined. OBJECTIVE To identify risk factors associated with 90-d readmission and reoperation following PCF surgery. METHODS Adults undergoing PCF from 2012 to 2020 were identified. Demographic and radiographic data, surgical characteristics, and 90-d outcomes were collected. Univariate analysis was performed using Student's t-test, chi square, and Fisher exact tests as appropriate. Multivariable logistic regression models with lasso penalty were used to analyze various risk factors. RESULTS A total of 259 patients were included. The 90-d readmission and reoperation rates were 9.3% and 4.6%, respectively. The most common reason for readmission was surgical site infection (SSI) (33.3%) followed by new neurological deficits (16.7%). Patients who smoked tobacco had 3-fold greater odds of readmission compared to nonsmokers (odds ratio [OR]: 3.48; 95% CI 1.87-6.67; P = .0001). Likewise, the most common reason for reoperation was SSI (33.3%) followed by seroma and implant failure (25.0% each). Smoking was also an independent risk factor for reoperation, associated with nearly 4-fold greater odds of return to the operating room (OR: 3.53; 95% CI 1.53-8.57; P = .003). CONCLUSION Smoking is a significant predictor of 90-d readmission and reoperation in patients undergoing PCF surgery. Smoking cessation should be strongly considered preoperatively in elective PCF cases to minimize the risk of 90-d readmission and reoperation.

Abstract
Seroma formation in a knee arthroplasty surgery is a rare complication. When seromas occur, they act as a nidus for bacterial growth and create an optimal environment for surgical site infections. In this case report, a 52-year-old woman presented with a seroma after multiple revision operations on the left knee. Owing to multiple failures of standard irrigation and drainage procedures to resolve the seroma, an orthoplastic colleague was consulted. Over five-and-a-half months, the patient underwent multiple procedures that failed to treat the seroma. However, in a final exploratory procedure, 3000 mg of urinary bladder matrix and negative pressure wound vacuum were placed. Seven months after the intervention, the patient had complete resolution.

Abstract
Tobacco use and narcotic medication have been associated with worse functional outcomes after surgery. Our goal was to investigate potential associations between smoking and preoperative opioid consumption in a geriatric population undergoing spine surgery, and their impact on postoperative outcomes. The records of 536 consecutive patients aged more than 65 years who underwent elective spinal surgery between November 2014 and August 2017 at a single institution were reviewed. Primary outcomes included rates of preoperative opioid consumption and postoperative hospital length of stay and complications. Males were more likely to be smokers than females (p < 0.001), whereas females were more likely to take opioid analgesics preoperatively (p = 0.022). Women with a history of smoking were more likely to have increased preoperative opioid consumption compared to those with no history of smoking (63.64% vs. 42.04%; p < 0.001). Such a relationship was not found in men. Subgroups analysis of female patients with a history of tobacco use comparing current and former smoker status showed that both groups exhibited increased preoperative opioid consumption compared to patients who never smoked (88.89% vs 42.04%; p < 0.001 for current users; 59.42% vs 42.04% for former users; p = 0.008). There was also a dose-depended relationship between smoking and increased preoperative opioid consumption. Geriatric female spine patients with a history of smoking have a higher incidence of preoperative opioid consumption. Opioid intake appears to increase with the number of pack-years, both in patients with a history of smoking and in those who currently smoke.

Abstract
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.

Spine J 2019; 19:2007-2012. [PMID: 31404654 DOI: 10.1016/j.spinee.2019.08.003] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2019] [Revised: 08/04/2019] [Accepted: 08/05/2019] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Over the last two decades, there has been a rapid increase in the use of cervical spine interbody fusion cages. Reoperation rate remains an important determinant of procedural efficacy and safety. PURPOSE To evaluate the rate and reasons for reoperations in cervical spondylosis patients undergoing anterior decompression and fusion using stand-alone cervical interbody fusion cages. STUDY DESIGN A retrospective study of 2,078 consecutive cases of degenerative cervical spine disease undergoing fusion using stand-alone cages. PATIENT SAMPLE Between January 2005 and December 2014, 2,078 patients underwent anterior cervical decompression and fusion using stand-alone cages in our institution. OUTCOME MEASURES The reoperations were analyzed and classified into early (during the first 90 days postoperatively) and late (after 90 days) reoperations. The rate and the causes of reoperation in both groups were reported and the results were compared. METHODS In 1,558 patients, a short segment fusion (≤2 levels) was performed, while the remaining 520 patients underwent a long segment fusion (≥3 levels). RESULTS The overall incidence of reoperation was 5.63%. The rate of early reoperations was 2.07%, mostly due to postoperative hematoma, and the rate of late reoperations was 3.56%, mostly due to adjacent segment disease. Revision due to pseudarthrosis was performed in 0.58% of cases. The early reoperation rate was significantly higher in the group with a long segment fusion, while the late reoperation rate was significantly higher in patients undergoing a short segment fusion. CONCLUSION Following anterior cervical decompression and fusion with a stand-alone cage, the overall incidence of symptomatic pseudarthrosis is low. Patients undergoing long segment fusion should be closely observed in the early postoperative period as they have a higher early complication rate. On the other hand, long segment fusions have a lower incidence of adjacent segment disease over the years.

Abstract
STUDY DESIGN Retrospective database analysis. OBJECTIVE To identify preoperative risk factors for emergency department (ED) visit and unplanned hospital readmission after primary anterior cervical discectomy and fusion (ACDF) at 30 and 90 days. SUMMARY OF BACKGROUND DATA Limited data exist to identify factors associated with ED visit or readmission after primary ACDF within the first 3 months following surgery. METHODS Patients undergoing ACDF from 2005 to 2012 were identified in the Statewide Planning and Research Cooperative System database. Multivariable regression models were created based on patient-level and surgical characteristics to identify independent risk factors for hospital revisit. RESULTS Of 41,813 patients identified, 2514 (6.0%) returned to the ED within 30 days of discharge. Risk factors included age < 35, black race (OR 1.19), Charlson Comorbidity index score > 1, length of stay (LOS) greater than 1 day (OR 1.23), and fusion of > 2 levels (OR 1.17). Four thousand six hundred nine (11.0%) patients returned to the ED within 90 days. Risk factors mirrored those at 30 days. Patients having private insurance or those discharged to rehab were less likely to present to the ED. One thousand three hundred ninety-four (3.3%) patients were readmitted by 30 days. Risk factors included male sex, Medicare, or Medicaid insurance (OR 1.71 and 1.79 respectively), Charlson comorbidity index > 1, discharge to a skilled nursing facility (OR 2.90), infectious/pathologic (OR 3.296), or traumatic (OR 1.409) surgical indication, LOS > 1 day (OR 1.66), or in-hospital complication. 2223 (5.3%) patients were readmitted by 90 days. Risk factors mirrored those at 30 days. No differences in readmission were seen based on race or number of levels fused. Patients aged 18 to 34 were less likely to be readmitted versus patients older than 35. CONCLUSION Insurance status, comorbidities, and LOS consistently predicted an unplanned hospital visit at 30 and 90 days. Although nondegenerative surgical indications and in-hospital complications did not predict ED visits, these factors increased the risk for readmission. LEVEL OF EVIDENCE 3.

Jain N, Brock JL, Phillips FM, Weaver T, Khan SN. Chronic preoperative opioid use is a risk factor for increased complications, resource use, and costs after cervical fusion. Spine J 2018; 18:1989-1998. [PMID: 29709553 DOI: 10.1016/j.spinee.2018.03.015] [Citation(s) in RCA: 64] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2017] [Revised: 02/12/2018] [Accepted: 03/26/2018] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT As health-care transitions to value-based models, there has been an increased focus on patient factors that can influence peri- and postoperative adverse events, resource use, and costs. Many studies have reported risk factors for systemic complications after cervical fusion, but none have studied chronic opioid therapy (COT) as a risk factor. PURPOSE The objective of this study was to answer the following questions from a large cohort of patients who underwent primary cervical fusion for degenerative pathology: (1) What is the patient profile associated with preoperative COT? (2) Is preoperative COT a risk factor for 90-day systemic complications, emergency department (ED) visits, readmission, and 1-year adverse events? (3) What are the risk factors and 1-year adverse events related to long-term postoperative opioid use? (4) How much did payers reimburse for management of complications and adverse events? STUDY DESIGN This is a retrospective review of Humana commercial insurance data (2007-Q3 2015). PATIENT SAMPLE The patient sample included 29,101 patients undergoing primary cervical fusion for degenerative pathology. METHODS Patients and procedures of interest were included using International Classification of Diseases (ICD) coding. Patients with opioid prescriptions for >6 months before surgery were considered as having preoperative COT. Patients with continued opioid use until 1-year after surgery were considered as long-term users. Descriptive analysis of patient cohorts has been done. Multiple-variable logistic regression analyses adjusting for approach, number of levels of surgery, discharge disposition, and comorbidities were done to answer first three study questions. Reimbursement data from insurers have been reported to answer our fourth study question. RESULTS Of the entire cohort, 6,643 (22.8%) had preoperative COT. Preoperative COT was associated with a higher risk of 90-day wound complications (odds ratio [OR] 1.39, 95% confidence interval [CI]: 1.16-1.66), all-cause 90-day ED visits (adjusted OR 1.22, 95% CI: 1.13-1.32), and pain-related ED visits (adjusted OR 1.39, 95% CI: 1.24-1.55). Patients who had preoperative COT were more likely to receive epidural or facet joint injections within 1 year after surgery (adjusted OR 1.68, 95% CI: 1.47-1.92). These patients were also more likely to undergo a repeat cervical fusion within a year than patients who did not have preoperative COT (adjusted OR 1.21, 95% CI: 1.01-1.43). Preoperative COT had a higher likelihood of long-term use after surgery (adjusted OR 4.72, 95% CI: 4.41-5.06). Long-term opioid use after surgery was associated with a higher risk of new-onsetconstipation (adjusted OR 1.34, 95% CI: 1.22-1.48). The risk of complications and adverse events was not found to be significant in patients with <3 months of preoperative opioid use or those who stopped opioids for at least 6 weeks before surgery. The cost of additional resource use for medications, ED visits, constipation, injections, and revision fusion ranged from $623 to $27,360 per patient. CONCLUSIONS Preoperative opioid use among patients who underwent cervical fusion increases complication rates, postoperative opioid usage, health-care resource use, and costs. These risks may be reduced by restricting the duration of preoperative opioid use or weaning off before surgery. Better understanding and management of pain in the preoperative period with judicious use of opioids is critical to enhance outcomes after cervical fusion surgery.

Abstract
STUDY DESIGN Retrospective state database analysis. OBJECTIVE To quantify the 30- and 90-day emergency department (ED) utilization and inpatient readmission rates after primary cervical arthrodesis, to stratify these findings by surgical approach, and to describe risk factors and conditions precipitating these events. SUMMARY OF BACKGROUND DATA Limited data exist on ED utilization and hospital readmission rates after cervical spine arthrodesis. METHODS The New York State all-payer health-care database was queried to identify all 87,045 patients who underwent primary subaxial cervical arthrodesis from 1997 through 2012. Demographic data and clinical information were extracted. Readmission data were available for the entire study period, whereas ED utilization data collection began later and was therefore analyzed starting in 2005. Incidences of these events within 30 and 90 days of discharge as well as trends over time were tabulated. The conditions prompting these encounters were also collected. Data were analyzed with respect to surgical approach. RESULTS The hospital readmission rate was 4.2% at 30 days and 6.2% at 90 days postoperatively. Approximately 6.2% of patients were managed in the ED without inpatient admission within 30 days and 11.3% within 90 days of surgery. The most common conditions prompting such events were dysphagia or dysphonia, respiratory complications, and infection. ED utilization and readmission rates were lowest after anterior surgeries. A preoperative Charlson Comorbidity Index of 1 or greater and traumatic pathologies were associated with increased risk of subsequent ED utilization or hospital readmission. Thirty-day hospital readmission rates declined after 2010, whereas 30-day ED utilization continued to increase. CONCLUSION Patient comorbidities, traumatic pathologies, and surgical approach are associated with increased postoperative complications. Anterior procedures carry the lowest risk, followed by posterior and then circumferential. Awareness of these findings should help to encourage development of strategies to minimize the rate of postoperative ED utilization and hospital readmission. LEVEL OF EVIDENCE 3.

Abstract
Nutritional optimization in patients undergoing spine surgery is important as improved surgical outcomes and decreased rates of complications have been noted in optimized patients. With the increasingly high numbers of elderly patient and patients with metabolic comorbidities undergoing spine procedures, perioperative nutritional status should be enhanced for the best possible surgical outcomes. Methods of optimization include preoperative screening with Nutritional Risk Score or other scoring systems, looking for changes in body mass index, detecting sarcopenia, and screening for metabolic abnormalities. Assessment of blood glucose, electrolytes, cholesterol, vitamin levels, visceral proteins, and lean body mass must be done preoperatively and close monitoring should be continued postoperatively. Albumin helps to determine the health status of patients before surgery and prealbumin as a predictor of surgical outcomes is being investigated. Malnourished patients should be given balanced diets replenishing key nutrient deficits, glucose should be maintained with sliding scale insulin or continuous infusions and immunonutrition may be implemented. Postoperatively, patients should initiate a diet as soon as possible to decrease overall length of stay and complication rates, facilitating return to normal activities.

Abstract
STUDY DESIGN A retrospective study. OBJECTIVES Anterior cervical fusion surgery is widely used procedure in cervical spondylosis. When considering the blood reinfusion strategies of cervical fusion surgery, the amount of blood loss is one of the key elements. We usually calculate the blood loss according to the surgical bleeding plus the postoperative drainage; however, this method ignores the possibility that there may be hidden blood loss (HBL). METHODS We performed a retrospective study to determine the risk factors for HBL in patients who underwent anterior cervical fusion surgery for degenerative spine from 2013 to 2016. The Pearson correlation, Spearman correlation, and multivariate liner analysis were used to find association between patient characteristics and HBL. RESULTS A total of 107 consecutive patients who underwent anterior cervical fusion surgery for degenerative spine in our hospital were reviewed. The amount of HBL was 261 mL, or 50% of the total blood loss. According to the model of multiple linear regression analysis, patient sex (P = 0.028) and American Society of Anesthesiologists physical status classification (P = 0.029) were independent risk factors contributing to HBL, but preoperative hematocrit was not (P = 0.741). CONCLUSIONS We concluded that sex and American Society of Anesthesiologists physical status classification were independent risk factors of HBL in anterior cervical fusion surgery. In addition, there was a high proportion of HBL in anterior cervical fusion. When considering the strategies of transfusion, we should pay attention to the risk factors for HBL.

Reduced Impact of Smoking Status on 30-Day Complication and Readmission Rates After Elective Spinal Fusion (≥3 Levels) for Adult Spine Deformity: A Single Institutional Study of 839 Patients. World Neurosurg 2017; 107:233-238. [PMID: 28790002 DOI: 10.1016/j.wneu.2017.07.174] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2017] [Revised: 07/26/2017] [Accepted: 07/29/2017] [Indexed: 11/24/2022]
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.

Abstract
Abstract
BACKGROUND
Healthcare readmissions are important causes of increased cost and have profound clinical impact. Thirty-day readmissions in spine surgery have been well documented. However, rates, causes, and outcomes are not well understood outside 30 d.
OBJECTIVE
To analyze 30- and 90-d readmissions for a retrospective cohort of anterior cervical discectomy and fusions (ACDF) and total disc replacement (TDR) for degenerative cervical conditions.
METHODS
The Nationwide Readmissions Database approximates 50% of all US hospitalizations with patient identifiers to track patients longitudinally. Patients greater than 18 yr old were identified. Rates of readmission for 30 and 90 d were calculated. Predictor variables, complications, outcomes, and costs were analyzed via univariate and multivariable analyses.
RESULTS
Between January and September 2013, 72 688 patients were identified. The 30- and 90-d readmission rates were 2.67% and 5.97%, respectively. The most prevalent reason for 30-d readmission was complication of medical/surgical care (20.3%), whereas for 90-d readmission it was degenerative spine etiology (19.2%). Common risk factors for 30- and 90-d readmission included older age, male gender, Medicare/Medicaid, prolonged initial length of stay, and various comorbidities. Unique risk factors for 30- and 90-d readmissions included adverse discharge disposition and mechanical implant-related complications, respectively. When comparing ACDF and TDR, ACDFs were associated with increased 90-d readmissions (6.0% vs 4.3%). The TDR cohort had a shorter length of stay, lower complication rate, and fewer adverse discharge dispositions.
CONCLUSION
Identification of readmission causes and predictors is important to potentially allow for changes in periperative management. Decreasing readmissions would improve patient outcomes and reduce healthcare costs.
