Abstract
Study design A bibliometric analysis. Objective To identify and analyze the top 100 cited articles in anterior cervical discectomy and fusion. Summary of Background Data Anterior cervical discectomy and fusion (ACDF) is one of the most routine surgical procedures in spine surgery. Many surgeons and academics have researched ACDF thoroughly and published numerous articles. However, there is no relevant bibliometric analysis. Therefore, our study aims to identify and analyze the top 100 cited articles in ACDF to identify the research trends. Methods We searched the Web of Science (WOS) Core Collection database with restrictions and identified the top 100 cited publications in ACDF for analysis. Results The citation counts of the top 100 cited publications ranged from 37 to 361 (mean 67.42). All studies were published between 2008 and 2019, with 2013 and 2015 the most prolific years. The journals Spine and Journal of Neurosurgery-Spine provided the majority of the articles. Overall, the 100 articles came from 12 countries, with the United States being the top producer, followed by China and South Korea. The most frequent keywords were "spine", "anterior cervical discectomy and fusion", "interbody fusion", 'arthrodesis', "follow-up", "decompression", and "ACDF". Conclusion ACDF has been regarded as a classical gold standard in anterior cervical surgery, and the emergence of new surgical procedures has not affected its status. Cervical disc arthroplasty still needs further research and development. As the first bibliometric analysis of ACDF, this bibliometric study is meant to provide guidance for clinicians and scholars to research the development trend of this field.

Abstract
STUDY DESIGN This was a systematic review study. PURPOSE This study aims to review current literature to determine the rates of complications in relation to spine surgery in ambulatory surgery centers (ASC). BACKGROUND Recent improvements in anesthesia, surgical techniques, and technological advances have facilitated a rise in the use of ASC. Despite the benefits and lower costs associated with ASCs, there is inconsistent reporting of complication rates. METHODS This systematic review was completed utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Pertinent studies were identified through Embase and PubMed databases using the search string ((("ambulatory surgery center") AND "spine surgery") AND "complications"). Articles were excluded if they did not report outpatient surgery in an ASC, did not define complications, were in a language other than English, were non-human studies, or if the articles were classified as reviews, book chapters, single case reports, or small case series (≤10 patients). The primary outcome was the frequency of complications with respect to various categories. RESULTS Our query identified 150 articles. After filtering relevance by title, abstract, and full text, 22 articles were included. After accounting for 2 studies that were conducted on the same study sample, a total of 11,245 patients were analyzed in this study. The most recent study reported results from May 2019. While 5 studies did not list their surgical technique, studies reported techniques including open (6), minimally invasive surgery (2), endoscopic (4), microsurgery (1), and combined techniques (4). The following rates of complications were determined: cardiac 0.29% (3/1027), vascular 0.25% (18/7116), pulmonary 0.60% (11/1839), gastrointestinal 1.12% (2/179), musculoskeletal/spine/operative 0.59% (24/4053), urologic 0.80% (2/250), transient neurological 0.67% (31/4616), persistent neurological 0.61% (9/1479), pain related 0.57% (20/3479), and wound site 0.68% (28/4092). CONCLUSIONS After literature review, this is the first study to comprehensively analyze the current state of literature reporting on the complication profile of all ASC spine surgery procedures. The most common complications were gastrointestinal (1.12%) and the most infrequent were vascular (0.25%). Case reports varied significantly with regard to the type and rate of complications reported. This study provides complication profiles to assist surgeons in counseling patients on the most realistic expectations.

Abstract
Spine procedures, including anterior cervical diskectomy and fusion (ACDF), are more commonly being performed in an outpatient setting to maximize value. Early complications after ACDF are rare but can have devastating consequences. The authors sought to determine risk factors for inpatient complications after 1-and 2-level ACDF by performing a retrospective review of the National Inpatient Sample (NIS) administrative database from 2006 through 2010. A total of 78,771 patients were identified. Multivariate logistic regression analysis was performed to identify preoperative risk factors for medical and surgical complications, including mortality, airway compromise, new neurologic deficit, and surgical-site infection. Inpatient mortality and overall complication rates were 0.074% and 3.73%, respectively. The risk of any medical complication was 3.13%. Airway compromise, neurologic deficit, and surgical-site infection occurred in 0.75%, 0.05%, and 0.04% of cases, respectively. Chronic kidney disease was the strongest predictor of mortality, with an odds ratio (OR) of 11.14 (P<.001). Airway complication was associated with age older than 65 years, male sex, myelopathy, diabetes mellitus, anemia, bleeding disorder, chronic obstructive pulmonary disease, obesity, and obstructive sleep apnea (P<.05). Preoperative diagnosis of myelopathy was most strongly associated with an increased rate of neurologic complication (OR, 6.67; P<.001). Anemia was associated with a significantly increased rate of surgical-site infection, with an OR of 14.34 (P<.001). Age older than 65 years; certain medical comorbidities, particularly kidney disease and anemia; and a preoperative diagnosis of myelopathy are associated with increased risk of early complication following ACDF surgery. Surgeons should consider these risk factors when deciding to perform ACDF surgery in an outpatient setting. [Orthopedics. 2021;44(5):e675-e681.].

Abstract
INTRODUCTION Anterior cervical discectomy and fusion (ACDF) is commonly performed to treat symptomatic cervical spondylolysis. Recently, many spine surgeons have begun performing ACDF in the outpatient setting. However, as this is a relatively new trend, many studies are either outdated or have small sample populations. The aim of this study was to evaluate outcomes following elective outpatient ACDF in comparison to those performed in the inpatient setting. METHODS Patients in Mariner Claims Database (2011-2017) undergoing outpatient elective ACDF were propensity score matched using age, gender and comorbidity burden. Chronic and peri-operative complications were assigned based on medical claims codes. All outcomes of interest were analyzed using multivariate logistic regression and compared to those undergoing inpatient ACDF. Significance was defined as p < 0.05 and adjusted with Bonferroni correction. RESULTS Outpatient surgery had significantly lower risk of dysphagia within 24 h in both single (OR 0.44, p < 0.001) and multilevel ACDF (OR 0.48, p < 0.001). Patients undergoing outpatient procedures also have lower risk of 90-day minor (Single OR 0.64, p < 0.001; Multilevel OR 0.52, p < 0.001) and major (Single OR 0.48, p < 0.001; Multilevel OR 0.57, p < 0.001) medical complications. Outpatient procedures were also associated with decreased hospital resource utilization with a noted lower risk of subsequent hospital readmission (Single OR 0.71, p < 0.001; Multilevel OR 0.60, p < 0.001) and ER visits (Single OR 0.84, p < 0.001; Multilevel OR 0.87, p < 0.001). CONCLUSION Outpatient single and multilevel ACDF may be performed safely in properly selected patients. Since there are relatively low rates of readmission and significant complications within the days following outpatient ACDF, many surgeons should consider transitioning carefully selected patients to an outpatient setting.

Abstract
STUDY DESIGN Broad narrative review. OBJECTIVE To review and summarize the current literature on the cost efficacy of performing ACDF, lumbar discectomy and short segment fusions of the lumbar spine performed in the outpatient setting. METHODS A thorough review of peer- reviewed literature was performed on the relative cost-savings, as well as guidelines, outcomes, and indications for successfully implementing outpatient protocols for routine spine procedures. RESULTS Primary elective 1-2 level ACDF can be safely performed in most patient populations with a higher patient satisfaction rate and no significant difference in 90-day reoperations and readmission rates, and a savings of 4000 to 41 305 USD per case. Lumbar discectomy performed through minimally invasive techniques has decreased recovery times with similar patient outcomes to open procedures. Performing lumbar microdiscectomy in the outpatient setting is safe, cheaper by as much as 12 934 USD per case and has better or equivalent outcomes to their inpatient counterparts. Unlike ACDF and lumbar microdiscectomy, short segment fusions are rarely performed in ASCs. However, with the advent of minimally invasive techniques paired with improved pain control, same-day discharge after lumbar fusion has limited clinical data but appears to have potential cost-savings up to 65-70% by reducing admissions. CONCLUSION Performing ACDF, lumbar discectomy and short segment fusions in the outpatient setting is a safe and effective way of reducing cost in select patient populations.

Abstract
BACKGROUND Anterior cervical diskectomy and fusion (ACDF) is a procedure for effectively relieving radiculopathy. Opioids are commonly overprescribed in postsurgical settings and prescriptions vary widely among providers. We identify trends in opioid dependence before and after ACDF. METHODS We used the Truven Health MarketScan data to identify adult patients undergoing ACDF for degenerative cervical spine conditions between 2009 and 2015. Patients were segregated in four cohorts of preoperative and postoperative opioid nondependence (ND) or dependence (D) with 15 months of postoperative follow-up. RESULTS A total of 25,403 patients with median age of 52 years (18-92) who underwent ACDF met the inclusion criteria. Breakdown of the four cohorts was as follows: prior nondependent who remain nondependent (NDND): 62.76% (n = 15,944); prior nondependent who become dependent (NDD): 4.6% (n = 1,168); prior dependent who become nondependent (DND): 14.03% (n = 3,564); and prior dependent who remain dependent (DD): 18.61% (n = 4,727). Opioid dependence decreased 9.43% postoperatively. Overall payments and 30-day readmissions increased 1.96 and 1.79 times for opioid dependent versus nondependent cohorts, respectively. Adjusted payments at 3 to 15 months were significantly increased for dependent cohorts with 3.56-fold increase for the DD cohort when compared with the NDND cohort. Length of stay, complications, medication refills, outpatient measures, and hospital admissions were also higher in those groups with postoperative opioid dependence when compared with those who were not opioid dependent. CONCLUSIONS Opioid dependence after ACDF is associated with increased hospital readmissions, complication rates at 30 days, and payments within 3 months and 3 to 15 months postdischarge. Overall opioid dependence was decreased after ACDF procedure, however, a smaller number of opioid-dependent and opioid-naive patients became dependent postoperatively and should be followed carefully.

Abstract
STUDY DESIGN Retrospective review of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database years 2012-2015. OBJECTIVE Compare the 30-day readmission and postoperative major complications rates of 2-level lumbar decompression performed in the ambulatory and the inpatient settings. SUMMARY OF BACKGROUND DATA In recent years, there is an increasing trend toward ambulatory spine surgery. However, there remains a concern regarding risks of readmission and postoperative morbidity after discharge. METHODS The ACS-NSQIP database from 2012 to 2015 was queried for adult patients who underwent elective 2-level lumbar decompression (CPT code 63047 accompanied with code 63048). A cohort of ambulatory lumbar decompression cases was matched 1:1 with an inpatient cohort after controlling for patient demographics, comorbidities, and complexity of the procedure. The primary outcome was the 30-day readmission rate. Secondary outcomes included a composite of 30-day postoperative major complications and hospital length of stay for hospitalized patients. RESULTS A total of 7505 patients met our study criteria. The ambulatory 2-level lumbar decompression surgery rate increased significantly over the study period from 28% in 2012 to 49% in 2015 (P<0.001). In the matched sample, there was no statistically significant difference in the 30-day readmission rate (odds ratio, 0.82; 95% confidence interval, 0.64-1.04; P=0.097) between the two cohorts; however, the ambulatory cohort had a lower 30-day postoperative major complication rate (odds ratio, 0.55; 95% confidence interval, 0.38-0.79; P=0.002). CONCLUSIONS After 2-level lumbar decompression performed on inpatient versus outpatient basis, the 30-day readmission rate is similar. However, the 30-day postoperative complication rate is significantly lower in the ambulatory setting. The reasons for these differences need further exploration. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND As healthcare costs rise, attempts are being made to perform an increasing proportion of spine surgery in ambulatory surgery centers (ASCs). ASCs are more efficient, both economically and functionally. There remains uncertainty regarding the safety of performing anterior lumbar procedures requiring vascular access, as little has been published on this subset of patients. METHODS This is a consecutive case series analysis of anterior lumbar spine surgeries that were performed in a free-standing ASC in a private-practice setting over a 1-year period, including anterior lumbar interbody fusion, artificial disc replacement, and hybrid procedures. The preoperative, intraoperative, and postoperative data recorded included age, gender, body mass index, tobacco use, and the presence of diabetes; level and procedure, operating room time, estimated blood loss, complications; discharge site, occurrence of reoperation, hospital admission, or any medical complication or infection over a 90-day period. RESULTS Fifty-one patients underwent 63 treated levels (34 artificial disc replacement, 29 anterior lumbar interbody fusion): 40 single-level, 10 two-level, one three-level. Average age was 45 years; 27 female, 24 males. None of the patients were diabetics, three were current smokers, seven were former smokers. Average body mass index was 27 ± 4 (range 16-36). Average total anesthesia time was 100 minutes (range 57-187 minutes). Average estimated blood loss was 23 mL (range 5-250 mL). Seventy-one percent of patients were discharged directly home, 29% to an aftercare facility. In the 30-day postoperative period there were no deaths, one hospital admission for pain, and no significant medical complications or surgical site infections. CONCLUSION In this consecutive case series artificial disc replacement or anterior lumbar interbody fusion was performed at 63 levels in 51 patients in the ASC setting with an observed major complication rate of zero and hospital unplanned admission rate of 2% (1/51). This provides some evidence that these procedures are safe to perform in the ASC setting. However, a highly experienced vascular surgeon and efficient surgical team, and strict patient selection criteria are all critical in making this possible.

Abstract
BACKGROUND Anterior cervical discectomy and fusion (ACDF) is being increasingly offered on an outpatient basis. However, the safety profile of outpatient ACDF remains poorly defined. OBJECTIVE To review the medical literature on the safety of outpatient ACDF. METHODS We systematically reviewed the literature for articles published before April 1, 2018, describing outpatient ACDF and associated complications, including incidence of reoperation, stroke, thrombolytic events, dysphagia, hematoma, and mortality. A random-effects analysis was performed comparing complications between the inpatient and outpatient groups. RESULTS We identified 21 articles that satisfied the selection criteria, of which 15 were comparative studies. Most of the existing studies were retrospective, with a lack of level I or II studies on this topic. We found no statistically significant difference between inpatient and outpatient ACDF in overall complications, incidence of stroke, thrombolytic events, dysphagia, and hematoma development. However, patients undergoing outpatient ACDF had lower reported reoperation rates (P < .001), mortality (P < .001), and hospitalization duration (P < .001). CONCLUSION Our meta-analysis indicates that there is a lack of high level of evidence studies regarding the safety of outpatient ACDF. However, the existing literature suggests that outpatient ACDF can be safe, with low complication rates comparable to inpatient ACDF in well-selected patients. Patients with advanced age and comorbidities such as obesity and significant myelopathy are likely not suitable for outpatient ACDF. Spine surgeons must carefully evaluate each patient to decide whether outpatient ACDF is a safe option. Higher quality, large prospective randomized control trials are needed to accurately demonstrate the safety profile of outpatient ACDF.

Abstract
STUDY DESIGN Retrospective cohort. OBJECTIVE Evaluate the safety profile of single- and multilevel cervical artificial disc replacement (ADR) performed in an outpatient setting. SUMMARY OF BACKGROUND DATA As healthcare costs rise, attempts are made to perform an increasing proportion of spine surgery in ambulatory surgery centers (ASCs). ASCs are more efficient, economically and functionally. Few studies have published on the safety profile of multilevel cervical ADR. METHODS We have performed an analysis of all consecutive cervical ADR surgeries that we performed in an ASC over a 9-month period, including multilevel and revision surgery. The pre-, intra-, and postoperative data recorded included age, sex, body mass index, tobacco use, and diabetes; level and procedure, operating room time, estimated blood loss (EBL), and complications; and discharge site, occurrence of reoperation, hospital admission, or any medical complication or infection over a 90-day period. RESULTS A total of 147 patients underwent 231 treated levels: 71 single-level, 76 multilevel: 69 two-level, 6 three-level, and 1 four-level. Average age was 50 ± 10 years; 71 women, 76 men. None of the patients had insulin-dependent diabetes, 4 were current smokers, and 16 were former smokers. Average body mass index was 26.8 ± 4.6 (range 18-40). Average total anesthesia time was 88 minutes (range 39-168 min). Average EBL was 15 mL (range 5-100 mL). Approximately 90.3% of patients were discharged directly home, 9.7% to an aftercare facility. In the 90-day postoperative period there were zero deaths and two hospital admissions (1.4%)-one for medical complication (0.7%) and one for a surgical site infection (0.7%). CONCLUSION In this consecutive case series we performed 231 ADRs in 147 patients in the outpatient setting, including multilevel and revision procedures, with 2 minor postoperative complications resulting in hospital unplanned admissions within 90 days. We believe that these procedures are safe to perform in an ASC. An efficient surgical team and careful patient selection criteria are critical in making this possible. LEVEL OF EVIDENCE 3.

In an effort to improve efficiency of care, ambulatory surgery centers (ASCs) have emerged as lower-cost options. Anterior cervical discectomy and fusion (ACDF) is one of the most prevalent spine surgeries performed and rarely requires overnight stays in the hospital, supporting its migration to the ASC. Recent analyses have called into question the safety of outpatient ACDF, potentially slowing its adoption. ASC-ACDF studies have largely been limited to small series, precluding an accurate assessment of safety.
OBJECTIVE
To analyze 2000 ASC-ACDF cases, describe patient selection and perioperative protocol, and report associated safety profile.
METHODS
A total of 2000 patients who underwent 1 to 3 level ACDF in a single ASC from 2006 to 2018 were included in this retrospective analysis. Patients were observed in a 4-h postanesthesia care unit (PACU) with a multimodal pain management regiment. Data were collected on patient demographics, comorbidities, operative details, and 30- and 90-d morbidity.
RESULTS
Of the 2000 patients, 10 (0.5%) required transfer to an inpatient setting within the 4-h observation. Reasons for transfer included hematoma (2), pain control (2), cerebrospinal fluid leak (1), and medical complications (5). Six patients (0.3%) underwent reoperation within 30 d. All-cause 30-d readmission was 1.9%.
CONCLUSION
An analysis of 2000 ACDF patients in an ASC setting with a standardized perioperative protocol demonstrates that surgical complications occur at a low rate (<1%) and can be appropriately diagnosed and managed in a 4-h PACU. In an effort to decrease healthcare costs, surgeons can safely perform ACDFs in an ASC utilizing patient selection criteria and perioperative management protocols similar to those reported here.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE To evaluate differences in patient factors, procedural factors, early outcomes and safety in mutlilevel anterior cervical discectomy and fusion (ACDF) in the inpatient versus outpatient setting. METHODS Patient demographics, operative factors, and outcomes of multilevel ACDF performed in an inpatient and outpatient setting were compared using Fisher's exact test for categorical and Student's t test for continuous variables. RESULTS Fifty-seven patients had surgery on an outpatient and 46 on an inpatient basis. Inpatients were older (56.7 vs 52.2 years, P = .012) and had a higher ASA (American Society of Anesthesiologists) class (P = .002). Sixty percent of 2-level cases were outpatient surgeries, compared with 35% of 3-level cases (P = .042). Outpatients had shorter operative times (71.26 vs 83.59 minutes, P < .0001) and shorter lengths of stay (8.51 vs 35.76 hours, P < .0001), lower blood loss (33.04 vs 45.87 mL, P = .003), and fewer in-hospital complications (5.3% vs 37.0%, P < .0001). Outpatients had better early outcomes in terms of 6-week Neck Disability Index (NDI) (27.97 vs 37.59, P = .014), visual analogue scale (VAS) neck (2.92 vs 4.02, P = .044), and Short Form-12 Physical Health Score (SF-12 PHS) (35.66 vs 30.79, P = .008). However, these differences did not persist at 6 months. CONCLUSIONS The results of our study suggest that multilevel ACDF can be performed safely in the outpatient setting without an increased risk of complications compared with the inpatient setting in an appropriately selected patient. Specifically, patients' age, ASA class, and number of levels being fused should be taken into consideration. At our institution, ASA class 3, body mass index >40 kg/m2, age >80 years, intubation time >2.5 hours, or not having a responsible adult with the patient warrant inpatient admission. Importantly, the setting of the surgery does not affect patient-reported outcomes.

Abstract
Background Outpatient anterior cervical discectomy and fusion (ACDF) is performed frequently, with studies demonstrating similar complication and readmission rates compared to traditional admission. Advantages include cost effectiveness, as well as lower risk of nosocomial infections and medical errors, which lead to quicker recovery and higher patient satisfaction. Protocols are needed to ensure that outpatient ACDF occurs safely. The objective of this study was to develop and implement a protocol with patient selection and discharge criteria for patients undergoing same-day discharge (SDD) ACDF and assess readmission rates. Methods A retrospective chart review was performed to identify patients undergoing 1 or 2 level primary ACDF between March 2016 and March 2017 who were eligible for SDD according to the institutional protocol (Figure 1, Table 2). Patients with identical surgery and discharge dates were grouped as SDD, and admitted patients were grouped as same-day admission (SDA). Using our electronic health record's analytics, readmissions in the 90-day postoperative period were identified. Results Of the 434 patients identified, 126 patients were SDD, and 308 were SDA. Baseline characteristics such as age, operative time, and time in the recovery room were significantly different between the 2 groups (Table 2). The average length of stay of admitted patients was 1.48 days, with 77% discharged on postoperative day 1. There was an overall, noninferior readmission rate of 0.8% in the SDD group compared to 0.6% in the SDA group (P = .86). Conclusions The results of this study support the feasibility of outpatient ACDF and add a patient selection and discharge criteria to the literature. Proper identification of suitable patients using our protocol results in a noninferior readmission rate, allowing surgeons to continue to safely perform these surgeries with a low readmission rate. Level of Evidence 3. Clinical Relevance SDD is safe in the appropriate patient population.

Abstract
Background: Outpatient surgery is becoming more common and is more cost-effective than inpatient surgery. Nonetheless, many surgeons and health care administrators are still hesitant to accept outpatient surgery for cervical degenerative spinal disease (C-DSD). This study assesses the types and rates of complications, hospital admissions, and reoperations after outpatient surgery of C-DSD.Methods: Complications, hospital admissions within 90 days of surgery, and reoperations within one year of surgery were recorded retrospectively in 1300 outpatients undergoing microsurgical decompression for C-DSD at the Oslofjord Clinic from 2008 to 2017. The surgical procedures performed were anterior cervical decompression and fusion (ACDF) in 1083 patients and posterior cervical foraminotomy in 217 patients.Results: The surgical mortality rate was 0%. Sixteen major complications were recorded in 15/1300 (1.2%) patients. The complications were neurological deterioration in four patients, postoperative hematoma in two, dural lesions with cerebrospinal fluid leakage in one, deep surgical-site infection in one, persistent hoarseness in three, and persistent dysphagia in five. The two potentially life-threatening hematomas were detected within the planned six-hour observation period. Two (0.2%) patients were admitted to hospital within hours of surgery completion with stroke-like signs and symptoms, and four (0.3%) patients were admitted to hospital within 90 days due to surgery-related events. The rate of reoperations for cervical radiculopathy within 12 months was 25/1171 (2%); eight patients' reoperations were due to inadequate primary decompression, one was due to recurrent disc herniation at the same level and side, and 16 were due to new-onset radiculopathy from an adjacent level or other side.Conclusions: Outpatient microsurgical decompression of the degenerative cervical spine in carefully selected patients appears to be safe and carries a low major complication rate, low hospital admission rate, and low one-year reoperation rate.

Abstract
BACKGROUND Outpatient cervical artificial disk replacement (ADR) is a promising candidate for cost reduction. Several studies have demonstrated low overall complications and minimal readmission in anterior cervical procedures. OBJECTIVE The objective of this study was to compare clinical outcomes and cost associated between inpatient and ambulatory setting ADR. MATERIALS AND METHODS Outcomes and cost were retrospectively analyzed for patients undergoing elective ADR in California, Florida, and New York from 2009 to 2011 in State Inpatient and Ambulatory Databases. RESULTS A total of 1789 index ADR procedures were identified in the inpatient database (State Inpatient Databases) compared with 370 procedures in the ambulatory cohort (State Ambulatory Surgery and Services Databases). Ambulatory patients presented to the emergency department 19 times (5.14%) within 30 days of the index procedure compared with 4.2% of inpatients. Four unique patients underwent readmission within 30 days in the ambulatory ADR cohort (1% total) compared with 2.2% in the inpatient ADR group. No ambulatory ADR patients underwent a reoperation within 30 days. Of the inpatient ADR group, 6 unique patients underwent reoperation within 30 days (0.34%, Charlson Comorbidity Index zero=0.28%, Charlson Comorbidity Index>0=0.6%). There was no significant difference in emergency department visit rate, inpatient readmission rate, or reoperation rates within 30 days of the index procedure between outpatient or inpatient ADR. Outpatient ADR is noninferior to inpatient ADR in all clinical outcomes. The direct cost was significantly lower in the outpatient ADR group ($11,059 vs. 17,033; P<0.001). The 90-day cumulative charges were significantly lower in the outpatient ADR group (mean $46,404.03 vs. $80,055; P<0.0001). CONCLUSIONS ADR can be performed in an ambulatory setting with comparable morbidity, readmission rates, and lower costs, to inpatient ADR.

Abstract
BACKGROUND The aim of our study was to compare the health care utilization and outcomes after surgery for anterior cranial fossa skull base meningioma (AFM), middle cranial fossa skull base meningioma (MFM), and posterior cranial fossa skull base meningioma (PFM) across the United States. METHODS We queried the MarketScan database using International Classification of Diseases, Ninth Revision and Current Procedural Terminology 4, from 2000 to 2016. We included adult patients who had at least 24 months of enrollment after the surgical procedure. The outcome of interest was length of hospital stay, disposition, complications, and reoperation after the procedure. RESULTS A cohort of 1191 patients was identified from the database. Less than half of patients (43.66%) were in the AFM cohort, 32.24% were in the MFM cohort, and only 24.1% were in the PFM cohort. Patients who underwent surgery for PFM had longer hospital stay (P = 0.0009), high complication rate (P = 0.0011), and less likely to be discharged home (P = 0.0013) during index hospitalization. There were no differences in overall payments at 12 months and 24 months among the cohorts. There was no significant difference in 90-day median payments among the groups ($66,212 [AFM] vs. $65,602 [MFM] and $71,837 [PFM]; P = 0.198). Male gender, commercial insurance (compared with Medicare), and higher comorbidity scores (score 3 compared with score 0) were associated with higher 90-day payments in the PFM cohort. CONCLUSIONS Overall payments (at 12 months and 24 months) and 90-day payments were not different among the cohorts. Patients with PFM had longer hospital stay and higher complication rate and were less likely to be discharged home with higher utilization of outpatient services at 12 months and 24 months.

Abstract
BACKGROUND Same-day surgery has been demonstrated to be a safe and cost-effective alternative to traditional inpatient surgery. Several studies have demonstrated no differences in the postoperative complication profile or 30-day hospital readmission rates with outpatient versus inpatient anterior cervical discectomy and fusion (ACDF). However, none of these studies compared the outcomes in elderly patients (aged >65 years) undergoing ACDF. Whether the results from previous studies can be applied to this subgroup pf patients remains unknown. The aim of the present study was to compare the 30-day hospital readmission rates for Medicare patients (aged >65 years) undergoing outpatient versus inpatient ACDF. METHODS We performed a retrospective analysis of a Medicare database, including data from 17,421 patients. Of the 17,421 patients, 16,386 had undergone inpatient ACDF and 1035, outpatient ACDF. Age, sex, comorbidities, postoperative complications, readmission rates, and overall financial costs were compared between the 2 cohorts. RESULTS In a Medicare sample (aged >65 years), inpatient ACDF was associated with a greater incidence of postoperative complications compared with outpatient ACDF. Outpatient surgery was associated with significantly lower rates of postoperative complications (urinary tract infection, surgical site infection, deep vein thrombosis, pulmonary embolism, and myocardial infarction) and significantly lower treatment costs (P ≤ 0.001). All-cause 30-day hospital readmission rates were also greater for inpatients (10.1% vs. 4%; P = 0.17). CONCLUSION The results from the present study suggest that outpatient ACDF appears to be safe and effective with low complication and readmission rates in a Medicare patient sample.

Abstract
OBJECTIVE In a large, consecutive series of patients treated with anterior cervical discectomy and fusion (ACDF) performed by a single surgeon, the authors compared the clinical and surgical outcomes of patients who underwent ACDF in an inpatient versus outpatient setting. METHODS Patients undergoing primary ACDF were retrospectively reviewed and stratified by surgical setting: hospital or ambulatory surgical center (ASC). Data regarding perioperative characteristics, including hospital length of stay and complications, were collected. Neck Disability Index (NDI) and visual analog scale (VAS) scores were used to analyze neck and arm pain in the preoperative period and at 6 weeks, 3 months, 6 months, and 12 months postoperatively. Postoperative outcomes were compared using chi-square analysis and linear regression. RESULTS The study included 272 consecutive patients undergoing a primary ACDF, of whom 172 patients underwent surgery at a hospital and 100 patients underwent surgery at an ASC. Patients undergoing ACDF in the hospital setting were older, more likely to be diabetic, and had a higher comorbidity burden. Patients receiving treatment in the ASC were more likely to carry Workers' Compensation insurance. Patients in the hospital cohort were more likely to have multilevel procedures, had greater blood loss, and experienced a longer length of stay. In the hospital cohort, 48.3% of patients were discharged within 24 hours, while 43.0% were discharged between 24 and 48 hours after admission. Both cohorts had similar VAS pain scores on postoperative day (POD) 0; however, the hospital cohort consumed more narcotics on POD 0. One patient in the ASC cohort had a pretracheal hematoma that was evacuated immediately in the same surgical center. There were 8 cases of dysphagia in the hospital cohort and 3 cases in the ASC cohort, all of which resolved before the 6-month follow-up. Both cohorts demonstrated similar NDI and VAS neck and arm pain scores preoperatively and at every postoperative time point. CONCLUSIONS Although patients undergoing ACDF in the hospital setting were older, had a greater comorbidity burden, and underwent surgery on more levels than patients undergoing ACDF at an outpatient center, this study demonstrated comparable surgical and clinical outcomes for both patient groups. Based on the results of this single surgeon's experience, 1- to 2-level ACDFs may be performed successfully in the outpatient setting in appropriately selected patient populations.

Abstract
STUDY DESIGN This was a retrospective review of prospectively collected data. OBJECTIVE To evaluate differences in patient factors, procedural factors, outcomes and safety in 2-level anterior cervical discectomy and fusion (ACDF) performed in ambulatory surgery centers (ASCs) versus the hospital setting. BACKGROUND Emphasis on reducing health care costs has led to numerous surgeries across specialties being performed in ASCs. Because of short operative times and moderate postoperative pain, 1-level ACDF is one of the most common spine surgeries successfully performed in ASCs. Despite the success of single-level ACDF, concerns over postoperative complications, including respiratory compromise have curtailed the performance of 2-level ACDF in ASCs. MATERIALS AND METHODS Patient demographics, operative factors and outcomes [blood loss, operative time, length of stay, complications and patient-reported outcomes (PROs)] of patients undergoing 2-level ACDF in an ASC and a hospital were compared using the Fisher exact test for categorical and the Student t test for continuous variables. RESULTS Of the 83 patients included, 25 underwent 2-level ACDF in an ASC, and 58 in a hospital. Mean age for the ASC group was 51.7±7.6 and 53.2±7.9 years for the hospital group (P=0.44). Body mass index was lower in the ASC group, at 27.3 kg/m versus 30.4 in the hospital group (P=0.03). Likewise, the ASC group had a lower ASA grade, favoring ASA 1 and 2 (P<0.001). There were no differences in blood loss (P=0.72) or complication rates, (P=0.16) with urinary retention being most common, and only 1 patient in the hospital setting requiring reintubation. In addition, no patients in the ASC setting required hospitalization. There were no differences in preoperative, 6-week and 6-month PROs. CONCLUSIONS The results of our study suggest that 2-level ACDF can be performed safely in the ASC setting without increased risk of complications compared with the hospital setting in an appropriately selected patient. Specifically, body mass index, and ASA class should be taken into consideration. Importantly, the setting of the surgery does not impact early PROs. LEVEL OF EVIDENCE Level 3.

Abstract
Background Several studies have compared outcomes between hospital-based (HBCs) and ambulatory surgery centers (ASCs) following anterior cervical discectomy and fusion (ACDF). However, the association between narcotic consumption and pain in the early postoperative period has not been well characterized. As such, the purpose of this study is to compare pain, narcotic consumption, and length of stay (LOS) between HBC and ASC patients undergoing same-day-discharge following ACDF. Methods A surgical registry of patients who underwent a primary, 1- or 2-level ACDF during 2013-2015 was reviewed. Patients were stratified by operative location. Differences in demographics were assessed using independent-sample t tests and chi-square analysis. The presence of an association between operative location and outcomes was analyzed using Poisson regression with robust error variance or linear regression adjusted for preoperative characteristics. Results A total of 76 patients were identified, of which 42 and 34 underwent surgery at an HBC or ASC, respectively. The HBC cohort had greater total (P < .001) and hourly (P = .034) narcotic consumption and prolonged LOS (P < .001). Over 90% of ASC patients consumed less than or equal to the 30th percentile (32.0 mg) of oral morphine equivalents (OME), whereas over 57% of HBC patients consumed greater than 32.0 mg OME. The HBC cohort consumed greater average doses of fentanyl and oxycodone (P < .001 for each). Conclusions This study demonstrates that patients undergoing same-day surgery for primary 1- or 2-level ACDF received more narcotics at HBCs compared to at ASCs. The increased narcotic consumption at HBCs may have resulted in longer LOS; however, this did not impact long-term pain, complications, or clinical outcomes. Clinical Relevance Patients scheduled to be discharged on postoperative day 0 following ACDF at HBCs may be able to receive fewer narcotics and be discharged sooner without compromising pain control or increasing their risk for complications.

Abstract
Background Outpatient surgery has been shown safe and effective for anterior cervical discectomy and fusion (ACDF), and more recently, for 1-level cervical disc arthroplasty (CDA). The purpose of this analysis is to compare the safety and efficiency of 1-level and 2-level CDA performed in an ambulatory surgery center (ASC) and in a hospital setting. Methods The study was a retrospective collection and analysis of data from consecutive CDA patients treated in ASCs compared to a historical control group of patients treated in hospital settings who were classified as outpatient (0 or 1-night stay) or inpatient (2 or more nights). Surgery time, blood loss, return to work, adverse events (AEs), and subsequent surgeries were compared. Results The sample consisted of 145 ASC patients, 348 hospital outpatients, and 65 hospital inpatients. A greater proportion of 2-level surgeries were performed in hospital than ASC. Surgery times were significantly shorter in ASCs than outpatient or inpatient 1-level (63.6 ± 21.6, 86.5 ± 35.8, and 116.7 ± 48.4 minutes, respectively) and 2-level (92.4 ± 37.3, 126.7 ± 43.8, and 140.3 ± 54.5 minutes, respectively) surgeries. Estimated blood loss was also significantly less in ASC than outpatient and inpatient 1-level (18.5 ± 30.6, 43.7 ± 35.9, and 85.7 ± 98.0 mL, respectively) and 2-level (21.1 ± 12.3, 67.8 ± 94.9, and 64.9 ± 66.1 mL). There were no hospital admissions and no subsequent surgeries among ASC patients. ASC patients had 1 AE (0.7%) and hospital patients had 10 AEs (2.4%). Working patients returned to work after a similar number of days off, but fewer ASC patients had returned to work by the end of the 90-day period. Conclusions Both 1- and 2-level CDA may be performed safely in an ASC. Surgeries in ASCs are of shorter duration and performed with less blood loss without increased AEs.

Abstract
INTRODUCTION In France, surgery for lumbar disc herniation is now being done in the outpatient ambulatory setting at select facilities. However, surgery for the cervical spine in this setting is controversial because of the dangers of neck hematoma. We wanted to share our experience with performing ambulatory anterior cervical discectomy in 30 patients at our facility. RESULTS Since 2014, 30 patients (16 men, 14 women; mean age of 47.2 years) with cervical radiculopathy due to single-level cervical disc disease (19 at C5-C6 and 11 at C6-C7) were operated at our ambulatory surgery center. After anterior cervical discectomy, cervical disc replacement was performed in 13 patients and fusion in 17 patients. The mean operative time was 38minutes and the mean duration of postoperative monitoring was 7hours 30minutes. The patients stayed at the healthcare facility for an average of 10hours 10minutes. One female patient (3%) was transferred to a standard hospital unit due to a neurological deficit requiring surgical revision with no cause identified. Two patients (7%) were rehospitalized on Day 1 due to dysphagia that resolved spontaneously. Thus the "ambulatory success rate" was 90% (27/30). There were no other complications and the overall satisfaction rate was excellent (9.6/10). DISCUSSION Outpatient anterior cervical discectomy is now widely performed in the United States. Ours is the first study of French patients undergoing this procedure. The complication rate was very low (<2%) and even lower than patients treated in an inpatient hospital setting in comparative studies. Note that our patients were carefully selected for outpatient surgery as certain risk factors for complications have previously been identified (age, 3+levels, comorbidities/ASA>2). No deaths in the first 30 days postoperative have been reported in the literature. Wound hematoma leading to airway compromise is rare in the ambulatory setting (0.2%). The few cases that occurred were detected early and the hematoma drained before the patient was discharged. Dysphagia is actually the most common complication (8 to 30%). CONCLUSION Cervical spine surgery can be performed in an ambulatory surgery center in carefully selected patients. Our criteria are patients less than 65 years of age, single-level disease, ASA<2, and standard cervical morphology. The complication and readmission rates are low. Careful hemostasis combined with close postoperative monitoring for at least 6hours helps to reduce the risk of neck hematoma. Prevention of postoperative dysphagia must be a focus of the care provided.

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
BACKGROUND CONTEXT With the changing landscape of health care, outpatient spine surgery is being more commonly performed to reduce cost and to improve efficiency. Anterior cervical discectomy and fusion (ACDF) is one of the most common spine surgeries performed and demand is expected to increase with an aging population. PURPOSE The objective of this study was to determine the nationwide trends and relative complication rates associated with outpatient ACDF. STUDY DESIGN/SETTING This is a large-scale retrospective case control study. PATIENT SAMPLE The patient sample included Humana-insured patients who underwent one- to two-level ACDF as either outpatients or inpatients from 2011 to 2016 OUTCOME MEASURES: The outcome measures included incidence and the adjusted odds ratio (OR) of postoperative medical and surgical complications within 1 year of the index surgery. MATERIALS AND METHODS A retrospective review was performed of the PearlDiver Humana insurance records database to identify patients undergoing one- to two-level ACDF (Current Procedural Terminology [CPT]-22551 and International Classification of Diseases [ICD]-9-816.2) as either outpatients or inpatients from 2011 to 2016. The incidence of perioperative medical and surgical complications was determined by querying for relevant ICD and CPT codes. Multivariate logistic regression adjusting for age, gender, and Charlson Comorbidity Index was used to calculate ORs of complications among outpatients relative to inpatients undergoing ACDF. RESULTS Cohorts of 1,215 patients who underwent outpatient ACDF and 10,964 patients who underwent inpatient ACDF were identified. The median age was in the 65-69 age group for both cohorts. The annual relative incidence of outpatient ACDF increased from 0.11 in 2011 to 0.22 in 2016 (R2=0.82, p=.04). Adjusting for age, gender, and comorbidities, patients undergoing outpatient ACDF were more likely to undergo revision surgery for posterior fusion at both 6 months (OR 1.58, confidence interval [CI] 1.27-1.96, p<.001) and 1 year (OR 1.79, CI 1.51-2.13, p<.001) postoperatively. Outpatient ACDF was also associated with a higher likelihood of revision anterior fusion at 1 year postoperatively (OR 1.46, CI 1.26-1.70, p<.001). Among medical complications, postoperative acute renal failure was more frequently associated with outpatient ACDF than inpatient ACDF (OR 1.25, CI 1.06-1.49, p=.010). Adjusted rates of all other queried surgical and medical complications were comparable. CONCLUSIONS Outpatient ACDF is increasing in frequency nationwide over the past several years. Nationwide data demonstrate a greater risk of perioperative surgical complications, including revision anterior and posterior fusion, as well as a higher risk of postoperative acute renal failure. Candidates for outpatient ACDF should be counseled and carefully selected to reduce these risks.

Abstract
STUDY DESIGN Retrospective, economic analysis. OBJECTIVE The aim of this study was to analyze the trend in hospital charge and payment adjusted to corresponding surgeon charge and payment for cervical and lumbar fusions in a Medicare sample population from 2005 to 2014. SUMMARY OF BACKGROUND DATA Previous studies have reported trends and variation in hospital charges and payments for spinal fusion, but none have incorporated surgeon data in analysis. Knowledge of the fiscal relationship between hospitals and surgeons over time will be important for stakeholders as we move toward bundled payments. METHODS A 5% Medicare sample was used to capture hospital and surgeon charges and payments related to cervical and lumbar fusion for degenerative disease between 2005 and 2014. We defined hospital charge multiplier (CM) as the ratio of hospital/surgeon charge. Similarly, the hospital/surgeon payment ratio was defined as hospital payment multiplier (PM). The year-wise and regional trend in patient profile, length of stay, discharge disposition, CM, and PM were studied for all fusion approaches separately. RESULTS A total of 40,965 patients, stratified as 15,854 cervical and 25,111 lumbar fusions, were included. The hospital had successively higher charges and payments relative to the surgeon from 2005 to 2014 for all fusions with an inverse relation to hospital length of stay. Increasing complexity of fusion such as for anterior-posterior cervical fusion had higher hospital reimbursements per dollar earned by the surgeon. There was regional variation in how much the hospital charged and received per surgeon dollar. CONCLUSION Hospital charge and payment relative to surgeon had an increasing trend despite a decreasing length of stay for all fusions. Although the hospital can receive higher payments for higher-risk patients, this risk is not reflected proportionally in surgeon payments. The shift toward value-based care with shared responsibility for outcomes and cost will likely rely on better aligning incentives between hospital and providers. LEVEL OF EVIDENCE 3.

Abstract
OBJECTIVE Outpatient anterior cervical discectomy and fusion (ACDF) is becoming more common and has been reported to offer advantages over inpatient procedures, including reducing nosocomial infections and costs, as well as improving patient satisfaction. The goal of this retrospective study was to evaluate and compare outcome parameters, complication rates, and costs between inpatient and outpatient ACDF cases performed by 1 surgeon at a single institution. METHODS In a retrospective study, the records of all patients who had undergone first-time ACDF performed by a single surgeon in the period from June 1, 2003, to January 31, 2016, were reviewed. Patients were categorized into 2 groups: those who had undergone ACDF as outpatients in a same-day surgical center and those who had undergone surgery in the hospital with a minimum 1-night stay. Outcomes for all patients were evaluated with respect to the following parameters: age, sex, length of stay, preoperative and postoperative pain (self-reported questionnaires), number of levels fused, fusion, and complications, as well as the presence of risk factors, such as an increased body mass index, smoking, and diabetes mellitus. RESULTS In total, 1123 patients were operated on, 485 (43%) men and 638 (57%) women, whose mean age was 50 years. The mean follow-up time was 25 months. Overall, 40.5% underwent 1-level surgery, 34.3% 2-level, 21.9% 3-level, and 3.2% 4-level. Only 5 patients had nonunion of vertebrae; thus, the fusion rate was 99.6%. Complications occurred in 40 patients (3.6%), with 9 having significant complications (0.8%). Five hundred sixty patients (49.9%) had same-day surgery, and 563 patients (50.1%) stayed overnight in the hospital. The inpatients were older, were more commonly male, and had a higher rate of diabetes. Smoking status did not influence the length of stay. Both groups had a statistically significant reduction in pain (expressed as a visual analog scale score) postoperatively with no significant difference between the groups. One- and 2-level surgeries were done significantly more often in the outpatient setting (p < 0.001). The complication rate was 4.1% in the outpatient group and 3.0% in the inpatient group; there was no statistically significant difference between the 2 groups (p = 0.339). Significantly more complications occurred with 3- and 4-level surgeries than with 1- and 2-level procedures (p < 0.001, chi-square test). The overall average inpatient cost for commercial insurance carriers was 26% higher than those for outpatient surgery. CONCLUSIONS Anterior cervical discectomy and fusion is safe for patients undergoing 1- or 2-level surgery, with a very significant rate of pain reduction and fusion and a low complication rate in both clinical settings. Outpatient and inpatient groups undergoing 3- or 4-level surgery had an increased risk of complications (compared with those undergoing 1- or 2-level surgery), with a negligible difference between the 2 groups. This finding suggests that these procedures can also be included as standard outpatient surgery. Comparable outcome parameters and the same complication rates between inpatient and outpatient groups support both operative environments.

Abstract
Abstract
Here, we systematically review clinical studies that report morbidity and outcomes data for cervical and lumbar surgeries performed in ambulatory surgery centers (ASCs). We focus on anterior cervical discectomy and fusion (ACDF), posterior cervical foraminotomy, cervical arthroplasty, lumbar microdiscectomy, lumbar laminectomy, and minimally invasive transforaminal interbody fusion (TLIF) and lateral lumbar interbody fusion, as these are prevalent and surgical spine procedures that are becoming more commonly performed in ASC settings.
A systematic search of PubMed was conducted, using combinations of the following phrases: “outpatient,” “ambulatory,” or “ASC” with “anterior cervical discectomy fusion,” “ACDF,” “cervical arthroplasty,” “lumbar,” “microdiscectomy,” “laminectomy,” “transforaminal lumbar interbody fusion,” “spine surgery,” or “TLIF.”
In reviewing the available literature to date, there is ample level 3 (retrospective comparisons) and level 4 (case series) evidence to support both the safety and effectiveness of outpatient cervical and lumbar surgery. While no level 1 or 2 (randomized clinical trials) evidence currently exists, the plethora of real-world clinical data creates a formidable argument for serious investments in ASCs for multiple spine procedures.

Abstract
STUDY DESIGN This is a retrospective study. OBJECTIVE To study the differences in definition of "inpatient" and "outpatient" [stated status vs. actual length of stay (LOS)], and the effect of defining populations based on the different definitions, for anterior cervical discectomy and fusion (ACDF) and lumbar discectomy procedures in the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. SUMMARY OF BACKGROUND DATA There has been an overall trend toward performing ACDF and lumbar discectomy in the outpatient setting. However, with the possibility of patients who underwent outpatient surgery staying overnight or longer at the hospital under "observation" status, the distinction of "inpatient" and "outpatient" is not clear. MATERIALS AND METHODS Patients who underwent ACDF or lumbar discectomy in the 2005-2014 ACS-NSQIP database were identified. Outpatient procedures were defined in 1 of 2 ways: either as being termed "outpatient" or hospital LOS=0. Differences in definitions were studied. Further, to evaluate the effect of the different definitions, 30-day outcomes were compared between "inpatient" and "outpatient" and between LOS>0 and LOS=0 for ACDF patients. RESULTS Of the 4123 "outpatient" ACDF patients, 919 had LOS=0, whereas 3204 had LOS>0. Of the 13,210 "inpatient" ACDF patients, 337 had LOS=0, whereas 12,873 had LOS>0. Of the 15,166 "outpatient" lumbar discectomy patients, 8968 had LOS=0, whereas 6198 had LOS>0. Of the 12,705 "inpatient" lumbar discectomy patients, 814 had LOS=0, whereas 11,891 had LOS>0. On multivariate analysis of ACDF patients, when comparing "inpatient" with "outpatient" and "LOS>0" with "LOS=0" there were differences in risks for adverse outcomes based on the definition of outpatient status. CONCLUSIONS When evaluating the ACS-NSQIP population, ACDF and lumbar discectomy procedures recorded as "outpatient" can be misleading and often did not correlate with same day discharge. These findings have significant impact on the interpretation of existing studies and define an area that needs clarification for future studies. LEVEL OF EVIDENCE Level 3.

Abstract
STUDY DESIGN Multicenter propensity score-adjusted retrospective cohort study. OBJECTIVE To determine baseline 30-day complication rates for anterior cervical discectomy and fusion (ACDF) and compare clinical complications for patients undergoing single-level ACDFs between inpatient and outpatient settings. SUMMARY OF BACKGROUND DATA ACDF remains the most common procedure in the treatment of a variety of cervical disc pathologies, making it a focus of quality improvement initiatives. Outpatient single-level ACDFs are becoming more common and offer advantages including reducing nosocomial infections and costs, as well as improved patient satisfaction. MATERIALS AND METHODS The 2011-2013 NSQIP datasets were queried to identify all patients who underwent single-level ACDF procedures using current procedural terminology codes. Outpatient and inpatient cohorts were matched 1:1 using propensity score analysis to assess short-term outcomes. The outcomes assessed included 30-day medical and surgical complications, reoperation, readmission, and mortality. RESULTS In total, 6940 patients underwent a single-level ACDF with an overall complication rate of 4.2%. A total of 5162 patients (74.4%) had an inpatient hospital stay after surgery, whereas 1778 patients (25.6%) had outpatient surgery. After matching based on preoperative and operative characteristics to account for potential confounders, the overall complication rate was higher in the inpatient arm compared with the outpatient arm (2.5% vs. 1.2%; P=0.003). The 30-day readmission rate was also higher but not significant in the inpatient group than the outpatient group (2.2% vs. 1.8%; P=0.355). Mortality was the same with 0.1% in both groups (P=0.564). CONCLUSIONS Patients undergoing outpatient single-level ACDF had a lower 30-day complication rates than those undergoing it in the inpatient setting. Outpatient surgery for single-level ACDF is safe and a favorable option for suitable patients. LEVEL OF EVIDENCE Level 3.

OBJECTIVE The aim of the present study was to examine how often spine surgery is being performed in an outpatient hospital setting versus a more "true" ambulatory setting, specifically ambulatory surgery centers (ASCs) in which admission and discharge are required on the same calendar day. SUMMARY OF BACKGROUND DATA Recent studies have assessed the safety, satisfactory clinical outcomes, and increasing utilization of both cervical and lumbar spinal surgeries performed in the outpatient setting. No studies have delineated between true ambulatory settings and outpatient hospitals when assessing the rates of these procedures. METHODS A retrospective review of the Truven Health Marketscan Research Databases was conducted for patients undergoing spine operations between 2003 and 2014. The frequency of each Common Procedural Terminology code was identified per year, and then categorized into each of "inpatient hospital," "outpatient hospital," or "ASC" in states that clearly define ASCs as facilities in which patients are discharged on the same calendar day of the operation, and do not stay overnight. RESULTS During the period between 2003 and 2014, the procedures that had the most dramatic increase as an outpatient hospital procedure included lumbar decompression laminotomy first level (18.7%-68.5%) and posterior cervical decompression laminectomy without facetectomy discectomy first level (0%-46.7%). ASC procedures had more modest increases during this time period with the most significant increases in lumbar decompression laminotomy first level (0.7%-10.6%) and posterior cervical decompression laminotomy first level (0%-23.4%). CONCLUSION "True" ambulatory surgeries are not increasing at the same rate as outpatient procedures with 23-hour observation capacity. Although prior studies have demonstrated the safety of outpatient spine surgery, one possible reason for this trend may be that surgeons feel that this safety may not be comparable to that of other outpatient procedures.

Abstract
STUDY DESIGN Delphi Panel expert panel consensus and narrative literature review. OBJECTIVE To obtain expert consensus on best practices for patient selection and perioperative decision making for outpatient anterior cervical surgery (anterior cervical disc fusion (ACDF) and cervical total disc replacement (CTDR)). SUMMARY OF BACKGROUND DATA Spine surgery in ambulatory settings is becoming a preferred option for both patients and providers. The transition from traditional inpatient environments has been enabled by innovation in anesthesia protocols and surgical technique, as well as favorable economics. Studies have demonstrated that anterior cervical surgery (ACDF and CTDR) can be performed safely on an outpatient basis. However, practice guidelines and evidence-based protocols to inform best practices for the safe and efficient performance of these procedures in same-day, ambulatory settings are lacking. METHODS A panel of five neurosurgeons, three anesthesiologists, one orthopedic spine surgeon, and a registered nurse was convened to comprise a multidisciplinary expert panel. A three-round modified-Delphi method was used to generate best-practice statements. Predetermined consensus was set at 70% for each best-practice statement. RESULTS A total of 94 consensus statements were reviewed by the panel. After three rounds of review, there was consensus for 83 best-practice statements, while 11 statements failed to achieve consensus. All statements within several perioperative categories (and subcategories) achieved consensus, including preoperative assessment (n = 8), home-care/follow-up (n = 2), second-stage recovery (n = 18), provider economics (n = 8), patient education (n = 14), discharge criteria (n = 4), and hypothermia prevention (n = 6). CONCLUSION This study obtained expert-panel consensus on best practices for patient selection and perioperative decision making for outpatient anterior cervical surgery (ACDF/CTDR). Given a paucity of guidelines and a lack of established care pathways for ACDF/CTDR in same-day, ambulatory settings, results from this study can supplement available evidence in support of local protocol development for providers considering a transition to the outpatient environment.

Abstract
STUDY DESIGN Retrospective study using the MarketScan longitudinal database (2006-2010). OBJECTIVE Compare complication rates between groups of patients undergoing anterior cervical discectomy and fusion (ACDF) procedures performed by surgeons with high versus low mean annual ACDF volume. SUMMARY OF BACKGROUND DATA Over the past decade the volume of ACDFs performed has increased, concurrent with greater appreciation of potential for associated complications. The effect of surgeon procedure volume on adverse events occurrence in the postoperative period has not been described. MATERIALS AND METHODS We evaluated the relationship between surgeon procedure volume and postoperative incidence of any complication using a multivariate logistic regression model. A total of 24,461 patients undergoing single and multiple level ACDFs were identified in the MarketScan database by Current Procedural Terminology coding. Annual surgeon volume was determined by tracking of anonymized surgeon identification numbers, with high-volume surgeons defined as those performing an average of at least 30 ACDF procedures annually. RESULTS Over 50% of unique surgeon identifiers reported <9 ACDF operations per year, whereas the highest decile reported a range of 44-101. High surgeon volume was protective for any complication [odds ratio (OR), 72; 95% confidence interval, 0.65-0.81; P<0.0001], with an adjusted number needed to harm of 44. Patients treated by high-volume physicians specifically had lower odds of dysphagia (2.22% vs. 3.08%; OR, 0.71; P<0.0013), neurological complications (0.33% vs. 0.64%; OR, 0.52; P<0.0107), new diagnosis of chronic pain (0.48% vs. 0.82%; OR, 0.58; P<0.0119), pulmonary complications (1.10% vs. 1.58%; OR, 0.69; P<0.0138), and other wound complications (0.06% vs. 0.22%; OR, 0.28; P<0.0242). CONCLUSIONS We demonstrate a possible association between higher surgeon procedure volume and decreased postoperative complications after ACDF. There was no difference observed in need for revision surgery or readmission rates.

Abstract
Abstract
BACKGROUND
Outpatient anterior cervical discectomy and fusion (ACDF) is a promising candidate for US healthcare cost reduction as several studies have demonstrated that overall complications are relatively low and early discharge can preserve high patient satisfaction, low morbidity, and minimal readmission.
OBJECTIVE
To compare clinical outcomes and associated costs between inpatient and ambulatory setting ACDF.
METHODS
Demographics, comorbidities, emergency department (ED) visits, readmissions, reoperation rates, and 90-d charges were retrospectively analyzed for patients undergoing elective ACDF in California, Florida, and New York from 2009 to 2011 in State Inpatient and Ambulatory Databases.
RESULTS
A total of 3135 ambulatory and 46 996 inpatient ACDFs were performed. Mean Charlson comorbidity index, length of stay, and mortality were 0.2, 0.4 d, and 0% in the ambulatory cohort and 0.4, 1.8 d, and 0.04% for inpatients (P < .0001). Ambulatory patients were younger (48.0 vs 53.1) and more likely to be Caucasian. One hundred sixty-eight ambulatory patients (5.4%) presented to the ED within 30 d (mean 11.3 d), 51 (1.6%) were readmitted, and 5 (0.2%) underwent reoperation. Among inpatient surgeries, 2607 patients (5.5%) presented to the ED within 30 d (mean 9.7 d), 1778 (3.8%) were readmitted (mean 6.3 d), and 200 (0.4%) underwent reoperation. Higher Charlson comorbidity index increased rate of ED visits (ambulatory operating room [OR] 1.285, P < .05; inpatient OR 1.289, P < .0001) and readmission (ambulatory OR 1.746, P < .0001; inpatient OR 1.685, P < .0001). Overall charges were significantly lower for ambulatory ACDFs ($33 362.51 vs $74 667.04; P < .0001).
CONCLUSION
ACDF can be performed in an ambulatory setting with comparable morbidity and readmission rates, and lower costs, to those performed in an inpatient setting.

Abstract
STUDY DESIGN Delphi process with multiple iterative rounds using a nominal group technique. OBJECTIVE The aim of this study was to use expert opinion to achieve consensus on various aspects of postoperative care following posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA Significant variability exists in postoperative care following PSF for AIS, despite a relatively healthy patient population and continuously improving operative techniques. Current practice appears based either on lesser quality studies or the perpetuation of long-standing protocols. METHODS An expert panel composed of 26 pediatric spine surgeons was selected. Using the Delphi process and iterative rounds using a nominal group technique, participants in this panel were presented with a detailed literature review and asked to voice opinion collectively during three rounds of voting (one electronic and two face-to-face). Agreement >80% was considered consensus. Interventions without consensus were discussed and revised, if feasible. RESULTS Consensus was reached to support 19 best practice guideline (BPG) measures for postoperative care addressing non-ICU admission, perioperative pain control, dietary management, physical therapy, postoperative radiographs, surgical bandage management, and indications for discharge. CONCLUSION We present a consensus-based BPG consisting of 19 recommendations for the postoperative management of patients following PSF for AIS. This can serve to reduce variability in practice in this area, help develop hospital specific protocols, and guide future research. LEVEL OF EVIDENCE 5.

Abstract
BACKGROUND Anterior cervical discectomy and fusion (ACDF) performed as an outpatient has become increasingly common for treating cervical spine pathology. Few reports have attempted to assess readmissions following outpatient ACDF. This study was performed to address this issue using population-based databases. METHODS The State Ambulatory Services Database (SASD) for New Jersey (NJ) from 2003-2012 was used for analysis. Patients receiving ACDF (defined as anterior cervical fusion (ICD-0 code=81.02) + excision of intervertebral disc (80.51)) were extracted; those with three or more levels fused (ICD-9 codes 81.63-81.64), cancer (ICD-9 codes 140-239), or trauma (ICD-9 codes=805.0-806.9) were excluded. A series of perioperative complications including durotomy, red blood cell transfusion, acute posthemorrhagic anemia, paraplegia (weakness), and mortality were examined. Propensity score matching (PSM) was used to adjust the analysis for patient age, race, sex, primary payer for care, and number of diagnoses. The NJ SASD defined readmission as admission to the same facility within seven days of initial discharge. RESULTS Two thousand sixteen (2,016) patients were found, 1,528 of whom had readmission data. Of these 1,528 patients, 83 (5.4%) required readmission. PSM was performed prior to comparing readmission versus non-readmission. While there was no difference in perioperative complications between the two groups, the small sample size of the readmission cohort prevented this analysis from having sufficient power. No patient requiring readmission had an initial length of stay greater than one day. CONCLUSION Based on a 10-year outpatient analysis, fewer than 6% of outpatient 1-2 level ACDFs require readmission. Future studies involving outpatients from several states will be necessary to determine whether these results of outpatient ACDF are applicable nationwide.

Abstract
STUDY DESIGN A retrospective study of patients undergoing anterior cervical discectomy and fusion (ACDF) in the prospective National Surgical Quality Improvement Program (NSQIP) database. OBJECTIVE To determine the most common reasons for readmission within 30 days after elective ACDF. SUMMARY OF BACKGROUND DATA ACDF is a commonly performed surgery that is safe and effective for treating a variety of cervical spine pathologies. With new quality-based reimbursements tied to readmissions within 30 days of discharge, better understanding of the causes of readmissions is, however, needed. METHODS Patients undergoing ACDF in the NSQIP database from 2012 to 2014 were reviewed. The overall rate of readmission and documented reasons for readmission were collected. Multivariate regression was then used to determine risk factors for readmissions. RESULTS A total of 17,088 patients undergoing elective ACDF were identified. There were 545 (3.2%) readmissions within 30 postoperative days. Of the readmitted patients, 293 (53.8%) were readmitted for nonsurgical site-related reasons, with neuropsychiatric (n = 44), cardiovascular (n = 39), and pneumonia (n = 37) being the most common reasons. A total of 184 patients (33.8%) were readmitted for surgical site-related reasons, with surgical site infection (n = 42), hemorrhage/hematoma (n = 42), and dysphagia (n = 32) being the most common reasons. A total of 84 patients (15.6%) had undocumented reasons for readmission. In multivariate analysis, only older age and higher American Society of Anesthesiologists class were independently associated with readmissions. CONCLUSION Most readmissions after ACDF were due to nonsurgical site-related reasons, suggesting the importance of careful patient selection, aggressive preoperative medical optimization, and adequate postoperative management.

Abstract
Background: Spine surgeons are being increasingly encouraged to perform cervical operations in outpatient ambulatory surgical centers (ASC). However, some studies/data coming out of these centers are provided by spine surgeons who are part or full owners/shareholders. In Florida, for example, there was a 50% increase in ASC (5349) established between 2000–2007; physicians had a stake (invested) in 83%, and outright owned 43% of ASC. Data regarding “excessive” surgery by ASC surgeon-owners from Idaho followed shortly thereafter. Methods: The risks/complications attributed to 3279 cervical spine operations performed in 6 ASC studies were reviewed. Several studies claimed 99% discharge rates the day of the surgery. They also claimed major complications were “picked up” within the average postoperative observation window (e.g., varying from 4–23 hours), allowing for appropriate treatment without further sequelae. Results: Morbidity rates for outpatient cervical spine ASC studies (e.g. some with conflicts of interest) varied up to 0.8–6%, whereas morbidity rates for 3 inpatient cervical studies ranged up to 19.3%. For both groups, morbidity included postoperative dysphagia, epidural hematomas, neck swelling, vocal cord paralysis, and neurological deterioration. Conclusions: Although we have no clear documentation as to their safety, “excessive” and progressively complex cervical surgical procedures are increasingly being performed in ASC. Furthermore, we cannot rely upon ASC-based data. At least some demonstrate an inherent conflict of interest and do not veridically report major morbidity/mortality rates for outpatient procedures. For now, cervical spine surgery performed in ASC would appear to be putting patients at increased risk for the benefit of their surgeon-owners.

Abstract
Background Anterior cervical discectomy and fusion (ACDF) is one of the most prevalent spine surgeries and neurosurgical procedures performed to treat a variety of disorders in the cervical spine. Over the last several years, ACDF has been done in the outpatient setting for less invasive approaches and exposures, as well as modified anesthetic and pain management techniques. Despite the fact that it may be innocuous in other parts of the body, complications in the spine can literally be fatal. The objective of this article is to evaluate the safety of outpatient surgery compared with inpatient surgery in the cervical spine for adult patients. Methods The multiple databases including Pubmed, Springer, EMBASE, EBSCO and China Journal Full-text Database were adopted to search for the relevant studies in English or Chinese. Full-text articles involving to the safety of outpatient cervical spine surgery were selected. Review Manager 5.0 was adopted to estimate the effects of the results among selected articles. Forest plots, sensitivity analysis and bias analysis for the articles included were also conducted. Chi-square tests were conducted with SPSS 20.0 software. Results Finally, 12 articles were included. The results of meta-analysis suggested that in the articles included, no death occurred, and compared with inpatient surgery, outpatient surgery has a similar risk (RR = 0.99, 95 % CI [0.98, 1.00], P = 0.02; P for heterogeneity = 0.47, I2 = 0 %). An I2 value of 0 % indicates no heterogeneity observed. All complications were occurred in both outpatients and inpatients. Among the studies selected, after the outpatient spine surgery, the highest incidences of complication were dysphagia (18/29) and hematoma (4/29). Compared with the overall complication rate in inpatient group, no significant difference was observed (x2 = 1.820, P = 0.177). Conclusion In this study, outpatient surgery has a similar risk with inpatient surgery, and no difference of morbidity between outpatient and inpatient was found. Because of short operative time and moderate postoperative pain, we believe that outpatient cervical spine surgery is a safe and convenient alternative procedure, which also decrease the cost of care. Besides, postoperative complications including dysphagia and hematoma should be noticed.

Abstract
OBJECTIVE
In an era of escalating health care costs and pressure to improve efficiency and cost of care, ambulatory surgery centers (ASCs) have emerged as lower-cost options for many surgical therapies. Anterior cervical discectomy and fusion (ACDF) is one of the most prevalent spine surgeries performed, and the frequency of its performance is rapidly increasing as the aging population grows. Although ASCs offer significant cost advantages over hospital-based surgical centers, concern over the safety of outpatient ACDF has slowed its adoption. The authors intended to 1) determine the safety of the first 1000 consecutive ACDF surgeries performed in their outpatient ASC, and 2) compare the safety of these outpatient ACDFs with that of consecutive ACDFs performed during the same time period in the hospital setting.
METHODS
A total of 1000 consecutive patients who underwent ACDF in an ACS (outpatient ACDF) and 484 consecutive patients who underwent ACDF at Vanderbilt University Hospital (inpatient ACDF) from 2006 to 2013 were included in this retrospective study of patients' medical records. Data were collected on patient demographics, comorbidities, operative details, and perioperative and 90-day morbidity. Perioperative morbidity and hospital readmission were compared between the outpatient and inpatient ACDF groups.
RESULTS
Of the first 1000 outpatient ACDF cases performed in the authors' ASC, 629 (62.9%) were 1-level and 365 (36.5%) were 2-level ACDFs. Mean patient age was 49.5 ± 8.6, and 484 (48.4%) were males. All patients were observed postoperatively at the ASC postanesthesia care unit (PACU) for 4 hours before being discharged home. Eight patients (0.8%) were transferred from the surgery center to the hospital postoperatively (for pain control [n = 3], chest pain and electrocardiogram changes [n = 2], intraoperative CSF leak [n = 1], postoperative hematoma [n = 1], and profound postoperative weakness and surgical reexploration [n = 1]). No perioperative deaths occurred. The 30-day hospital readmission rate was 2.2%. All 90-day surgical morbidity was similar between outpatient and inpatient cohorts for both 1-level and 2-level ACDFs.
CONCLUSIONS
An analysis of 1000 consecutive patients who underwent ACDF in an outpatient setting demonstrates that surgical complications occur at a low rate (1%) and can be appropriately diagnosed and managed in a 4-hour ASC PACU window. Comparison with an inpatient ACDF surgery cohort demonstrated similar results, highlighting that ACDF can be safely performed in the outpatient ambulatory surgery setting without compromising surgical safety. In an effort to decrease costs of care, surgeons can safely perform 1- and 2-level ACDFs in an ASC environment.

Abstract
Technological advances in neurosurgery, aided by improvements in anesthesia have resulted in surgery that is faster, simpler and safer with excellent perioperative recovery. As a result of improved outcomes, several centers are performing certain neurosurgical procedures on an outpatient basis; where patients arrive at the hospital the morning of their procedure and leave the hospital the same evening, thus avoiding an overnight stay in the hospital. Apart from the medical benefits of the outpatient procedure, its impact on patient satisfaction is substantial. The economic benefits are extremely favorable for the patient, physician, as well as the hospital. However, due to skepticism surrounding medico-legal aspects, and how radical the concept at first sounds, these procedures have not gained widespread popularity. We provide an overview of outpatient neurosurgery discussing results, outcomes related to patients' quality of life, and impact on the economic burden on currently burgeoning health care costs.

Abstract
Abstract
BACKGROUND:
There is an increasing demand for surgery of degenerative spinal disease. Limited healthcare resources draw attention to the need for cost-effective treatments. Outpatient surgery, when safe and feasible, is more cost effective than inpatient surgery.
OBJECTIVE:
To study types and rates of complications after outpatient lumbar and cervical spine decompressions.
METHODS:
Complications were recorded prospectively in 1449 (1073 lumbar, 376 cervical) outpatients undergoing microsurgical decompression for degenerative spinal disease at the private Oslofjord Clinic from 2008 to 2013.
RESULTS:
Surgical mortality was 0%. A total of 51 (3.5%) minor and major complications were recorded in 51 patients. Three (0.2%) patients had to be admitted to a hospital the day of surgery. Twenty-two (1.5%) patients were admitted to a hospital within 3 months due to surgery-related events. The encountered complications were postoperative hematoma (0.6%), neurological deterioration (0.3%), deep wound infection (0.9%), dural lesions with cerebrospinal fluid leakage (1.0%), persistent dysphagia (0.1%), persistent hoarseness (0.1%), and severe pain/headache (0.4%). All of the life-threatening hematomas were detected within 6 and 3 hours after cervical and lumbar surgery, respectively.
CONCLUSION:
This series of 1449 consecutive outpatient microsurgical spine decompressions adds to the growing literature in favor of outpatient spinal surgery in properly selected patients. In our study, 99.8% of the patients were successfully discharged either to their homes or to a hotel on the day of surgery. The overall complication rate was 3.5%, surgical mortality was 0%, and only 1.5% had to be admitted to a hospital within 3 months after surgery.

Abstract
Study Design Systematic review. Study Rationale As the length of stay after cervical spine surgery has decreased substantially, the feasibility and safety of outpatient cervical spine surgery come into question. Although minimal length of stay is a targeted metric for quality and costs for medical centers, the safety of outpatient cervical spine surgery has not been clearly defined. Objective The objective of this article is to evaluate the safety of inpatient versus outpatient surgery in the cervical spine for adult patients with symptomatic or asymptomatic degenerative disc disease. Methods A systematic review of the literature was undertaken for articles published through February 19, 2014. Electronic databases and the bibliographies of key articles were searched to identify comparative studies evaluating the safety of inpatient versus outpatient surgery in the cervical spine. Spinal cord stimulation, spinal injections, and diagnostic procedures were excluded. Two independent reviewers assessed the strength of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system, and disagreements were resolved by consensus. Results Five studies that met the inclusion criteria were identified. One study reported low risk of hematoma (0% of outpatients and 1.6% of inpatients). Two studies reported on mortality and both reported no deaths in either group following surgery. Dysphagia risks ranged from 0 to 10% of outpatients and 1.6 to 5% of inpatients, and infection risks ranged from 0 to 1% of outpatients and 2 to 2.8% of inpatients. One study reported that no (0) outpatients were readmitted to the hospital due to a complication, compared with four inpatients (7%). The overall strength of evidence was insufficient for all safety outcomes examined. Conclusion Though the studies in our systematic review did not suggest an increased risk of complication with outpatient cervical spine surgery, the strength of evidence to make a recommendation was insufficient. Further study is needed to more clearly define the role of outpatient cervical spine surgery.

Abstract
Study Design Retrospective population-based observational study. Objective To assess the growth of cervical spine surgery performed in an outpatient setting. Methods A retrospective study was conducted using the United States Healthcare Cost and Utilization Project's State Inpatient and Ambulatory Surgery Databases for California, New York, Florida, and Maryland from 2005 to 2009. Current Procedural Terminology, fourth revision (CPT-4) and International Classification of Diseases, ninth revision Clinical Modification (ICD-9-CM) codes were used to identify operations for degenerative cervical spine diseases in adults (age > 20 years). Disposition and complication rates were examined. Results There was an increase in cervical spine surgeries performed in an ambulatory setting during the study period. Anterior cervical diskectomy and fusion accounted for 68% of outpatient procedures; posterior decompression made up 21%. Younger patients predominantly underwent anterior fusion procedures, and patients in the eighth and ninth decades of life had more posterior decompressions. Charlson comorbidity index and complication rates were substantially lower for ambulatory cases when compared with inpatients. The majority (>99%) of patients were discharged home following ambulatory surgery. Conclusions Recently, the number of cervical spine surgeries has increased in general, and more of these procedures are being performed in an ambulatory setting. The majority (>99%) of patients are discharged home but the nature of analyzing administrative data limits accurate assessment of postoperative complications and thus patient safety. This increase in outpatient cervical spine surgery necessitates further discussion of its safety.

Preoperative factors affecting length of stay after elective anterior cervical discectomy and fusion with and without corpectomy: a multivariate analysis of an academic center cohort. Spine (Phila Pa 1976) 2014; 39:939-46. [PMID: 24718069 PMCID: PMC4024365 DOI: 10.1097/brs.0000000000000307] [Citation(s) in RCA: 39] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/01/2023]
Abstract
STUDY DESIGN Retrospective cohort study of 183 patients who underwent elective anterior cervical discectomy and fusion (ACDF) at a single institution during a 2-year period. OBJECTIVE To determine which preoperative factors were independently associated with a prolonged hospital length of stay (LOS) after ACDF. SUMMARY OF BACKGROUND DATA ACDF has become the most common treatment modality for addressing cervical spine pathology. Extended LOS after ACDF is associated with increased costs and complications. There is a lack of conclusive data for factors affecting LOS after ACDF. This study aims to create a multivariate model to determine the association of various patient and operative characteristics with LOS after ACDF. METHODS Patients who underwent elective ACDF at a single academic institution between January 2011 and February 2013 were identified using billing records. Their charts were reviewed to collect variables available preoperatively such as patient demographics, comorbidities, and surgery planned. Patients were categorized as normal or extended LOS, with extended LOS defined as LOS more than the 75th percentile. A multivariate logistic regression was used to determine which factors were independently associated with extended LOS. RESULTS A total of 183 patients with ACDF were identified. The average LOS for this cohort was 2.0 ± 2.5 days (mean ± standard deviation). Extended LOS was defined as 3 days or more. Multivariate analysis revealed that preoperative factors independently associated with extended LOS were history of nonspinal malignancy (odds ratio [OR] = 4.9), history of pulmonary disease (OR = 4.0), and procedures that included corpectomy (OR = 4.5). CONCLUSION Patients with a history of nonspinal malignancy or pulmonary disease, as well as patients who underwent corpectomy, were more likely to have an extended LOS (ORs, 4.0-4.9). Of significant note, other factors that one might expect to be associated with extended LOS did not independently predict extended LOS in this analysis. LEVEL OF EVIDENCE 3.
