Abstract
OBJECTIVE The primary objective of this investigation is to systematically scrutinize extant surgical studies delineating Four-Level Anterior Cervical Discectomy and Fusion (4L ACDF), with a specific emphasis on elucidating reported surgical indications, clinical and radiological outcomes, fusion rates, lordosis correction, and the spectrum of complication rates. METHODS The literature review was conducted in adherence to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, employing the MEDLINE (PubMed), Embase, and Scopus databases. This analysis encompasses studies implementing the 4L ACDF procedure, with detailed extraction of pertinent data pertaining to surgical methodologies, types of employed interbody cages, clinical and radiological endpoints, rates of fusion, and the incidence of complications. RESULTS Among the 15 studies satisfying inclusion criteria, a marginal increment in the year 2022 (21.4%) was discerned, with a preponderance of study representation emanating from China (35.7%) and the United States (28.6%). 50% of the studies were single-surgeon studies. Concerning follow-up, studies exhibited variability, with 42.9% concentrating on periods of five years or less, and an equivalent proportion extending beyond this timeframe. Across the amalgamated cohort of 2457 patients, males constituted 51.6%, manifesting a mean age range of 52.2-61.3 years. Indications for surgery included radiculopathy (26.9%) and myelopathy (46.9%), with a predilection for involvement at C3-7 (24.9%). Meta-analysis yielded an overall complication rate of 16.258% (CI 95%: 14.823%-17.772%). Dysphagia (4.563%), haematoma (1.525%), hoarseness (0.205%), C5 palsy (0.176%) were the most prevalent complications of 4L ACDF. Fusion rates ranging from 41.3% to 94% were documented. CONCLUSION The 4L ACDF is commonly performed to address mylopathy and radiculopathy. While the surgery carries a complication rate of around 16%, its effectiveness in achieving bone fusion can vary considerably.

Abstract
BACKGROUND Ambulatory spinal surgery is a care delivery model meant to improve patient outcomes and reduce in-hospital length of stay (LOS). We reviewed the experience of implementing an outpatient spine surgery program in Manitoba, Canada and highlight elements that can be used to reduce LOS and re-presentation to hospital. METHODS This is a retrospective cohort study using data from the Canadian Spine Outcomes and Research Network and independent chart review of adult patients undergoing outpatient spinal surgery between 2015 and 2018. Patient demographics, comorbidities, perioperative course, LOS, and readmissions were analyzed. RESULTS We included 217 patients in this analysis. The mean LOS was 36.2 hours; 71.98% of patients had a LOS <24 hours. A Kruskal-Wallis test by ranks analysis was conducted and identified 7 elements that correlated with prolonged length of stay (>1 day): age older than 55 (P = 0.027), body mass index >25 (P = 0.045), uncontrolled diabetes (P = 0.015), preoperative use of opioid medication (P = 0.024), American Society of Anesthesiologists classification of 3 (P = 0.023), non-minimally invasive surgical approach, and multilevel procedures. Most (94.1%) of the patients with none of these elements (i.e., age <55, low body mass index, normal/controlled diabetes, minimal preoperative opioid use, American Society of Anesthesiologist classification <3, minimally invasive surgical procedure) had a favorable LOS, <24 hours, compared with 84.8% with 1 risk factor, 80.4% of those with two, 69.8% with three, 53.1% with four, and 31.2% with 5 or more. A small number of patients (14.98%) presented to an emergency department within 90 days of their operation, and there was a 6.28% readmission rate. CONCLUSIONS We identified several patient and surgical criteria that correlate with prolonged length of stays following planned ambulatory spine surgery. Our work provides some empiric evidence to help guide surgeons on which patients and approaches are ideal for ambulatory surgery.

Abstract
BACKGROUND Anterior cervical discectomy and fusion (ACDF) and cervical disc arthroplasty (CDA) are attractive targets for transition to the outpatient setting. We assessed the prevalence of rapid responses and major complications in the inpatient setting following 1 or 2-level ACDFs and CDAs. We evaluated factors that may place patients at greater risk for a rapid response or a postoperative complication. METHODS This was an institutional review board-approved, retrospective cohort study of adults undergoing 1 or 2-level ACDF or CDA at 1 hospital over a 2-year period (2018 and 2019). Data on patient demographic characteristics, surgical procedures, and comorbidities were collected. Rapid response events were identified by hospital floor staff and involved acute changes in a patient's clinical condition. Complications were events that were life-threatening, required an intervention, or led to delayed hospital discharge. RESULTS In this study, 1,040 patients were included: 888 underwent ACDF and 152 underwent CDA. Thirty-six patients (3.5%) experienced a rapid response event; 22% occurred >24 hours after extubation. Patients having a rapid response event had a significantly higher risk of developing a complication (risk ratio, 10; p < 0.01) and had a significantly longer hospital stay. Twenty-four patients (2.3%) experienced acute complications; 71% occurred >6 hours after extubation. Patients with a complication were older and more likely to be current or former smokers, have chronic obstructive pulmonary disease, have asthma, and have an American Society of Anesthesiologists (ASA) score of >2. The length of the surgical procedure was significantly longer in patients who developed a complication. All patients who developed dysphagia had a surgical procedure involving C4-C5 or more cephalad. Patients with a rapid response event or complication were more commonly undergoing revision surgical procedures. CONCLUSIONS Rapid response and complications are uncommon following 1 or 2-level ACDFs or CDAs but portend a longer hospital stay and increased morbidity. Revision surgical procedures place patients at higher risk for rapid responses and complications. Additionally, older patients, patients with chronic obstructive pulmonary disease or asthma, patients who are current or former smokers, and patients who have an ASA score of ≥3 are at increased risk for postoperative complications.

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
Anterior cervical discectomy and fusion (ACDF), despite its possible complications, remains the gold standard for the surgical treatment of patients with radiculopathy and/or myelopathy caused by cervical intervertebral disc herniation or spondylosis. Despite its high rate of incidence, postoperative dysphagia following ACDF is still poorly understood; its pathogenesis remains relatively unknown, and its risk factors are still a subject of debate. The aim of this study is to review the incidence, pathogenesis, diagnosis, and methods of prevention of dysphagia in ACDF patients. To this end, a literature review was conducted based on the PubMed internet database. Article titles were searched by using the following keywords: “dysphagia” and “anterior cervical discectomy and fusion” or “ACDF”. The search was limited to prospective clinical studies evaluating dysphagia after ACDF surgery. Studies published in non-English languages, retrospective studies, cadaveric studies, reviews, case reports, study protocols, and commentary studies were excluded. Initially, 335 studies were identified after a primary search. After the application of the exclusion criteria, 73 studies remained for the final analysis. This literature review focused on identifying the rate of dysphagia and the various risk factors leading to this complication by comparing and evaluating the current literature with a wide spectrum of heterogeneity concerning patients, surgeons, and surgical techniques. A mean dysphagia rate of 19.4% (95% CI: 9.6%-29.1%) based on the findings of the included studies correlating dysphagia directly with ACDF procedures was calculated. Various established risk factors leading to dysphagia include the female sex, smoking, the surgical approach, rhBMP-2 use, and multilevel surgery, while zero-profile devices seem to reduce dysphagia risk. The diagnosis is based on clinical and radiological findings, especially prevertebral soft-tissue swelling. However, videofluoroscopic and endoscopic studies have been recently used for the evaluation of dysphagia. The role of local administration of steroids in the prevention of dysphagia has not yet been clarified. This review underscores the prevailing rudimentary understanding of the problem of dysphagia after ACDF procedures and highlights the need for more sensitive, factor-specific studies for understanding the impact of various risk factors on the incidence rate of dysphagia.

Abstract
Introduction Anterior cervical discectomy and fusion (ACDF) is the gold standard for the treatment of cervical spondylosis. However, new techniques, technologies, and improved implants have aided surgeons in reducing operative time with enhanced patient outcomes. Impregnated hydroxyapatite polyetheretherketone (HA PEEK) cages (Arena-C HA®, LESspine Inc. Malden, MA) are one such option that has aimed to increase the fusion rate. The authors herein aimed to assess the use of HA PEEK interbody cages by looking at outcomes, complications, and radiographic fusion. Methods The medical records of 41 consecutive patients undergoing single-level ACDF with impregnated HA PEEK cages (group 1) were compared to the control group of 47 patients who had single-level ACDF without impregnated HA PEEK cages (group 2). Outcomes assessed included Visual Analog Scale (VAS) neck, Neck Disability Index (NDI) scores, radiographic fusion, and complication rates. Results Of the 41 patients in group 1 (HA PEEK), 48% were female population with a mean age of 58.5+/- 1.7 years and BMI 29.7+/-1.2 kg/m2. Of the 47 patients in group 2 (non-HA PEEK), 53% were female with a mean age of 54.3+/- 1.2 years and BMI 27.8+/-0.8 kg/m2. Using t-test, there was a statistically significant intergroup difference in two-year VAS neck and NDI scores, p=0.007, and p=0.001, respectively. Radiographic fusion occurred as early as three months in the HA PEEK group. Conclusions This study has demonstrated the equivalence of impregnated HA PEEK cages in single-level ACDF. Significant improvements were seen in VAS and NDI scores in the HA PEEK group. There was no incidence of heterotopic bone formation or reaction to HA PEEK cages. Additionally, a trend toward fusion was seen in HA PEEK patients as early as three to five months compared to seven to eight months for the ACDF group. We conclude that HA PEEK cages can be safely placed with excellent outcomes. However, further studies are required to look at added benefits.

Abstract
Background: This is an updated analysis of the morbidity and mortality of cervical surgery performed in outpatient/same day (OSD) (Postoperative care unit [PACU] observation 4–6 h), and ambulatory surgicenters (ASC: PACU 23 h) versus inpatient facilities (IF). Methods: We analyzed 19 predominantly level III (retrospective) and IV (case series) studies regarding the morbidity/mortality of cervical surgery performed in OSC/ASC versus IF. Results: A “selection bias” clearly favored operating on younger/healthier patients to undergo cervical surgery in OSD/ASC centers resulting in better outcomes. Alternatively, those selected for cervical procedures to be performed in IF classically demonstrated multiple major comorbidities (i.e. advanced age, diabetes, high body mass index, severe myelopathy, smoking, 3–4 level disease, and other comorbidities) and had poorer outcomes. Further, within the typical 4–6 h. PACU “observation window,” OSD facilities “picked up” most major postoperative complications, and typically showed 0% mortality rates. Nevertheless, the author’s review of 2 wrongful death suits (i.e. prior to 2018) arising from OSD ACDF cervical surgery demonstrated that there are probably many more mortalities occurring following discharges from OSD where cervical operations are being performed that are going underreported/unreported. Conclusion: “Selection bias” favors choosing younger/healthier patients to undergoing cervical surgery in OSD/ ASC facilities resulting in better outcomes. Atlernatively, choosing older patients with greater comorbidities for IF surgery correlated with poorer results. Although most OSD cervical series report 0% mortality rates, a review of 2 wrongful death suits by just one neurosurgeon prior to 2018 showed there are probably many more mortalities resulting from OSD cervical surgery than have been reported.

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.

Abstract
We seek to determine the outcomes of patients undergoing outpatient-based ALIF compared to a consecutive series of inpatient based ALIF performed during the same time period. 58 consecutive patients at a single outpatient surgery center underwent ALIF from June 2015 - August 2017 and 79 ALIF's were performed at 2 Inpatient hospitals. Electronic medical records were reviewed for perioperative and postoperative complications as well as secondary interventions. 62 patients met inclusion criteria (29 Outpatient, 33 Inpatient). The inpatient group was significantly older (44 vs 51; p = 0.01). There were 8 postoperative complications. There was no difference in secondary interventions; 28 patients underwent a total of 36 interventions postoperatively for pain. Secondary interventions were performed at an average of 128(outpatient) and 158(inpatient) days (p = 0.55). There was no difference in outcome scores between the inpatient/outpatient groups at any time. Patients receiving a secondary intervention showed no significant improvement in Back VAS scores but, demonstrated a strong trend (p = 0.06) towards leg pain improvement. Patients who did not undergo secondary intervention had significant improvement in both Back and Leg VAS scores at all time points (p < 0.05). Outpatient ALIF is a safe and reproducible procedure with complication rates consistent with or lower than published rates. Patients outcome scores were no different in the inpatient versus outpatient group. Interestingly, there was a high number of secondary interventions performed in both groups. Patients undergoing a secondary procedure did not get statistically significant improvement in Back VAS but, demonstrated a strong trend in Leg VAS patient reported outcome scores.

Abstract
BACKGROUND Examining the costs of single- and multilevel anterior cervical discectomy and fusion (ACDF) is important for the identification of cost drivers and potentially reducing patient costs. A novel tool at our institution provides direct costs for the identification of potential drivers. OBJECTIVE To assess perioperative healthcare costs for patients undergoing an ACDF. METHODS Patients who underwent an elective ACDF between July 2011 and January 2017 were identified retrospectively. Factors adding to total cost were placed into subcategories to identify the most significant contributors, and potential drivers of total cost were evaluated using a multivariable linear regression model. RESULTS A total of 465 patients (mean, age 53 ± 12 yr, 54% male) met the inclusion criteria for this study. The distribution of total cost was broken down into supplies/implants (39%), facility utilization (37%), physician fees (14%), pharmacy (7%), imaging (2%), and laboratory studies (1%). A multivariable linear regression analysis showed that total cost was significantly affected by the number of levels operated on, operating room time, and length of stay. Costs also showed a narrow distribution with few outliers and did not vary significantly over time. CONCLUSION These results suggest that facility utilization and supplies/implants are the predominant cost contributors, accounting for 76% of the total cost of ACDF procedures. Efforts at lowering costs within these categories should make the most impact on providing more cost-effective care.

Abstract
Abstract
BACKGROUND
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
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
The positive safety profile and potential cost savings associated with ambulatory spine surgery have resulted in an increasing number of spine procedures being performed on an outpatient basis. As indications become more inclusive and the variety and volume of ambulatory procedures grow, the incidence of complications may rise. Limiting adverse events in the outpatient setting starts with patient selection. Surgeons should be aware of the potential complications and associated risk factors for common ambulatory spine procedures and employ strategies to limit and appropriately manage them. Protocols which include patient education, multimodal anesthesia and analgesia, standardized post-operative monitoring, and safe discharge planning are also essential for maximizing safety in the ambulatory setting.

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
OBJECTIVE This study aims to assess the relationship of comorbidities and postoperative complications to rates of readmission for geriatric patients undergoing anterior cervical discectomy and fusion (ACDF) involving more than 2 levels on an inpatient or outpatient basis. With the rising costs of healthcare in the United States, understanding the safety and efficacy of performing common surgical interventions (including ACDF) as outpatient procedures could prove to be of great economic impact.Objective This study aims to assess the effect of comorbidities and postoperative complications on the rates of readmission of geriatric patients undergoing multilevel anterior cervical discectomy and fusion (ACDF) procedures (i.e., ACDF involving 3 or more levels) on an inpatient or outpatient basis. Same-day surgery has been demonstrated to be a safe and cost-effective alternative to the traditional inpatient option for many surgical interventions. With the rising costs of healthcare, understanding the safety and efficacy of performing common surgical interventions as outpatient procedures could prove to be of great economic impact. METHODS The study population included total of 2492 patients: 2348 inpatients and 144 outpatients having ACDF procedures involving 3 or more levels in the Medicare Standard Analytical Files database. Age, sex, comorbidities, postoperative complications, readmission rates, and surgical procedure charges were compared between both cohorts. For selected variables, logistic regression was used to model odds ratios for various comorbidities against readmission rates for both inpatient and outpatient cohorts. Chi-square tests were also calculated to compare these comorbidities with readmission in each cohort. RESULTS Overall complication rates within 30 postoperative days were greater for inpatients than for outpatients (44.2% vs 12.5%, p < 0.001). More inpatients developed postoperative urinary tract infection (7.9% vs 0%, p < 0.001), and the inpatient cohort had increased risk of readmission with comorbidities of anemia (OR 1.52, p < 0.001), smoking (OR 2.12, p < 0.001), and BMI ≥ 30 (OR 1.43, p < 0.001). Outpatients had increased risk of readmission with comorbidities of anemia (OR 2.78, p = 0.047), diabetes mellitus type 1 or 2 (OR 3.25, p = 0.033), and BMI ≥ 30 (OR 3.95, p = 0.008). Inpatients also had increased readmission risk with a postoperative complication of surgical site infection (OR 2.38, p < 0.001). The average charges for inpatient multilevel ACDF were significantly higher than for multilevel ACDF performed on an outpatient basis ($12,734.27 vs $12,152.18, p = 0.0019). CONCLUSIONS This study suggests that ACDF surgery involving 3 or more levels performed as an outpatient procedure in the geriatric population may be associated with lower rates of readmissions, complications, and surgical charges.

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
OBJECTIVE With the costs related to the United States medical system constantly rising, efforts are being made to turn traditional inpatient procedures into outpatient same-day surgeries. In this study the authors looked at the various comorbidities and perioperative complications and their impact on readmission rates of patients undergoing outpatient versus inpatient 3- and 4-level anterior cervical discectomy and fusion (ACDF). METHODS This was a retrospective study of 337 3- and 4- level ACDF procedures in 332 patients (5 patients had both primary and revision surgeries that were included in this total of 337 procedures) between May 2012 and June 2017. In total, 331 procedures were analyzed, as 6 patients were lost to follow-up. Outpatient surgery was performed for 299 procedures (102 4-level procedures and 197 3-level procedures), and inpatient surgery was performed for 32 procedures (11 4-level procedures and 21 3-level procedures). Age, sex, comorbidities, number of fusion levels, pain level, and perioperative complications were compared between both cohorts. RESULTS Analysis was performed for 331 3- and 4-level ACDF procedures done at 6 different hospitals. The overall 30-day readmission rate was 1.2% (outpatient 3 [1.0%] vs inpatient 1 [3.1%], p = 0.847). Outpatients had increased readmission risk, with comorbidities of coronary artery disease (OR 1.058, p = 0.039), autoimmune disease (OR 1.142, p = 0.006), diabetes (OR 1.056, p = 0.001), and chronic kidney disease (OR 0.933, p = 0.035). Perioperative complications of delirium (OR 2.709, p < 0.001) and surgical site infection (OR 2.709, p < 0.001) were associated with increased risk of 30-day hospital readmission in outpatients compared to inpatients. CONCLUSIONS This study demonstrates the safety and effectiveness of 3- and 4-level ACDF surgery, although various comorbidities and perioperative complications may lead to higher readmission rates. Patient selection for outpatient 3- and 4-level ACDF cases might play a role in the safety of performing these procedures in the ambulatory setting, but further studies are needed to accurately identify which factors are most pertinent for appropriate selection.

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 This study looks at the various comorbidities and postoperative complications and their impact on readmission rates of patients undergoing outpatient versus inpatient 1- and 2-level anterior cervical discectomy and fusion (ACDF). With increasing costs within the United States medical system, one emerging cost-saving strategy is to evolve traditional inpatient procedures into outpatient same-day surgeries. However, patient safety remains a crucial priority. METHODS A total of 28,427 patients were analyzed, with 26,368 undergoing inpatient ACDF surgery and 2059 undergoing outpatient ACDF surgery. Age, sex, comorbidities, postoperative complications, readmission rates, and overall financial cost were compared between both cohorts. RESULTS Data from 28,427 one- and two-level ACDF procedures that were split between inpatient and outpatient were collected. Thirty-day readmission rates were significantly lower in outpatients than inpatients (4% vs. 10.1%, P < 0.001). Inpatients had higher rates of urinary tract infection (2.4% vs. 1.4%), deep vein thrombosis (0.6% vs. 0%), and myocardial infarction (0.2% vs. 0%), whereas outpatients had higher rates of pulmonary embolism (7.7% vs. 0.4%). Outpatients had increased readmission risk with comorbidities of diabetes (odds ratio [OR], 48.93; P < 0.001), smoking (OR, 4.6; P < 0.001), body mass index ≥30 (OR, 2392; P < 0.001). The average cost of outpatient surgery was less than that of inpatient surgery ($7774.8 vs. $7956.75, P = 0.0444). CONCLUSION This study suggests that in the appropriately selected patients, ACDF can safely be performed in an outpatient setting.

Exclusion criteria for dysphagia for outpatient single-level anterior cervical discectomy and fusion using inpatient data from a spine registry. Clin Neurol Neurosurg 2019; 180:28-33. [PMID: 30877898 DOI: 10.1016/j.clineuro.2019.03.008] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2018] [Revised: 02/06/2019] [Accepted: 03/10/2019] [Indexed: 11/27/2022]
Abstract
OBJECTIVES Reported incidence of dysphagia after ACDFs has been as high as 79%. There, however, have been no studies that have specifically looked at developing a criteria for reducing the incidence of dysphagia for outpatient ACDFs. The aim of this study was to determine the risks factors for significant dysphagia that will exclude patients from outpatient single-level anterior cervical discectomy and fusions (ACDFs). PATIENTS AND METHODS Using the Kaiser Permanente Spine registry database, between January 2009 and September 2013, we identified all inpatients (there were no outpatients) who underwent primary elective one-level ACDFs. A cohort of patients were identified with in-hospital length of stay (LOS) > 48 h in which the reason for continued admission was primarily significant dysphagia (DG). Patient's demographics and intraoperative data (ACDF levels (upper [C2-3, C3-4], middle [C4-5, C5-6], lower [C6-7, C7-T1]), and operative times (<100, 100-199, ≥ 200, minutes)) was used to determine risk factors for dysphagia. RESULTS We found 747 single-level ACDF cases with a cohort of 239 (32.0%) who met the criteria for dysphagia (DG) with > 48 h admission. The DG group and non-dysphagia group (NDG) had similar demographics. Diabetes was excluded from regression analysis due to the low frequency. Compared to the lower spine level (C5-6, C7-T1), the upper spine level (C2-3, C3-4) ACDF had a higher likelihood for dysphagia (OR = 2.23, 95% CI = 1.35-3.68, p = 0.0016); no difference was found for middle spine level (C4-5, C5-6) ACDF. CONCLUSION Single-level ACDF at the upper cervical spine (C2-3, C3-4) was found to be the only risk factor for dysphagia with LOS > 48 h based on inpatient data from a spine registry. Age, BMI category, gender, ASA classification, smoking, and operative time were not predictive factors. These findings should be used for excluding patients who undergo outpatient single-level ACDF surgery to reduce significant postoperative dysphagia.

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
Background The authors aim to demonstrate the feasibility, outcomes and fusion rate of a standalone PEEK cage in the outpatient setting. Methods 48 consecutive patients undergoing standalone ACDF (S-ACDF) (Group 1) were compared to control group of 49 patients who had ACDF with ACP (Group 2). Results Analysis of follow-up at the one year period postoperative outcomes between groups 1 and 2 demonstrated no intergroup statistical significant difference in VAS neck, arm and NDI scores p = 0.414, 0.06 and p = 0.328 respectively. Conclusion We conclude that S-ACDF can be safely done in an ambulatory surgery center with satisfactory clinical and patient-reported outcomes.

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
Spine surgery is a key target for cost reduction within the United States health care system. One possible strategy involves the transition of inpatient surgeries to the ambulatory setting. Lumbar laminectomy with or without discectomy, lumbar fusion, anterior cervical discectomy and fusion, and cervical disc arthroplasty all represent promising candidates for outpatient surgeries in select populations. In this focused review, the authors clarify the different definitions used in studies describing outpatient spine surgery. They also discuss the body of evidence supporting each of these procedures and summarize the proposed cost savings. Finally, they examine several patient- and surgeon-specific considerations to highlight the barriers in translating outpatient spine surgery into actual practice.

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 Retrospective database review. 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 A single-center, retrospective study. OBJECTIVE The aim of this study was to determine the safety and outcomes of total disc replacement (TDR) as an outpatient procedure in the ambulatory surgery center (ASC). SUMMARY OF BACKGROUND DATA Anterior cervical discectomy and fusion (ACDF) has been demonstrated to be safe in the outpatient setting, as the awareness of same-day surgery procedures is on the rise due to better outcome and shorter recovery time. There is a need for motion preservation in a subset of patients TDR provides a solution. Transitioning spine surgery to the outpatient setting including cervical TDR is the next logical step. METHODS The medical records of 55 consecutive patients undergoing single level TDR (Group 1) were compared with our control group of 55 patients who had single-level ACDF (Group 2). Outcomes assessed included Visual Analogue Scale (VAS) neck, arm, neck disability index (NDI) scores, and complication rate. RESULTS Fifty-five patients in Group 1 (TDR, 60%) were male with the group's mean age being 42.6 ± 1.4 years and body mass index (BMI) 24.8 ± 1.2 kg/m. Fifty-five patients in Group 2 (ACDF), 57%, were male with the group's mean age being 53 ± 1.0 years and mean BMI 27.9 ± 0.8 kg/m. There was no statistically significant intergroup difference in 2-year VAS neck, arm and NDI scores. Dysphagia was the most common postoperative compliant in both groups (six patients), with no intergroup significance, P = 0.4. CONCLUSION In the ambulatory setting, TDR has shown statistical significant intragroup improvement in VAS neck, arm pain scores, and NDI scores (P < 0.001). In this study, no patients reported serious complications, no incidence of hematoma formation, or worsening postop pain. We conclude that single-level TDR can be safely done in an ASC with satisfactory clinical and patient-reported outcomes. This is comparable to single-level ACDF in the outpatient setting and previous 2-year TDR studies. LEVEL OF EVIDENCE 3.

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 Retrospective cohort. OBJECTIVE To compare time to discharge for anterior cervical discectomy and fusions (ACDF) when performed as either a first case versus later surgical start times. SUMMARY OF BACKGROUND DATA ACDF is a commonly performed spinal procedure that typically has a short acute recovery period. With an increasing focus on reducing hospital costs and a shift toward outpatient surgical practices, early patient discharge has become a priority for hospitals and physicians alike. However, the impact of surgery start time on the ability for same-day discharge has not been explored in spine surgery. METHODS A surgical database of patients who underwent ACDF from 2013 to 2015 was reviewed. Patients were stratified into two cohorts: those whose surgery was the first of the day (early cohort), and those who underwent later surgeries. Baseline patient characteristics and perioperative variables were compared between cohorts using Student t test and χ test. Same-day discharge was tested for association with surgical start time using Poisson regression with robust error variance controlling for preoperative variables. RESULTS A total of 106 patients, divided into early and late cohorts of 60 and 46 patients, respectively, were included in the analysis. There were no significant differences in pre- or perioperative characteristics between cohorts (). Same-day discharge was achieved in 36.8% (n = 39) of all ACDF patients. The later cohort was significantly more likely to require an overnight stay compared with the early cohort (RR = 1.61 ± 0.30; P = 0.010).(Table is included in full-text article.)CONCLUSION.: Patients undergoing ACDF later in the day are at a higher risk for staying overnight than those who have the first surgery of the day. These results may influence operative scheduling, as performing ACDFs early in the day may result in a greater likelihood of same-day discharge, eliminating the increased resource utilization associated with an overnight hospital stay.

Abstract
BACKGROUND As the cost of health-care delivery rises in the era of bundled payments for care, there is an impetus toward minimizing hospitalization. Evidence to support the safety of open reduction and internal fixation (ORIF) of ankle fractures in the outpatient setting is largely anecdotal. METHODS Patients who underwent ORIF from 2005 to 2013 were identified via postoperative diagnoses of ankle fracture and Current Procedural Terminology codes; patients with open fractures and patients who were emergency cases were excluded. Patients undergoing inpatient and outpatient surgical procedures were propensity score-matched to reduce differences in the baseline characteristics. Primary tracked outcomes included medical and surgical complications, readmission, and reoperation within 30 days of the procedure. Binary logistic regression models were created that determined the risk-adjusted relationship between admission status and primary outcomes. RESULTS Outpatient surgical procedures were associated with lower rates of urinary tract infection (0.4% compared with 0.9%; p = 0.041), pneumonia (0.0% compared with 0.5%; p = 0.002), venous thromboembolic events (0.3% compared with 0.8%; p = 0.049), and bleeding requiring transfusion (0.1% compared with 0.6%; p = 0.012). Outpatient status was independently associated with reduced 30-day medical morbidity (odds ratio, 0.344 [95% confidence interval, 0.201 to 0.589]). No significant differences were uncovered with respect to surgical complications (p = 0.076), unplanned reoperations (p = 0.301), and unplanned readmissions (p = 0.358). CONCLUSIONS In patients with closed fractures and minimal comorbidities, outpatient ORIF was associated with reduced risk of select 30-day medical morbidity and no difference in surgical morbidity, reoperations, and readmissions relative to inpatient. Factors unaccounted for when creating matched cohorts may impact our results. Our findings lend reassurance to surgeons who defer admission for low-risk patients.

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.

OBJECTIVE To prospectively assess the incidence of dysphagia and to present the serial changes of each finding in the videofluoroscopic swallow study (VFSS) after anterior cervical discectomy and fusion (ACDF). SUMMARY OF BACKGROUND DATA The reported incidence of dysphagia after ACDF has varied widely, and the serial changes of dysphagia using VFSS have not been clearly determined yet. METHODS Data of 47 patients preoperatively and at 1 week and 1 month postoperatively were used for the analyses. The Bazaz dysphagia score and VFSS were checked preoperatively and at 1 week and 1 month postoperatively. The presence of aspiration or penetration, amount of vallecular and pyriform sinus residues, functional dysphagia scale, temporal parameters of oral transit time, pharyngeal transit time, and pharyngeal delay time (PDT) were evaluated from the VFSS data. RESULTS Incidences of dysphagia measured by the Bazaz dysphagia score were 83.0% at 1 week and 59.6% at 1 month after ACDF. Although the incidence of aspiration was 4.3% and the incidence of penetration was 36.2% at 1 week and 25.5% at 1 month after surgery, none of the patients had aspiration pneumonia. The number of patients with vallecular and pyriform sinus residues significantly increased after ACDF. Further, there were no statistically significant changes at all time points in terms of oral transit time, pharyngeal transit time, and pharyngeal delay time. CONCLUSIONS Dysphagia is common until 1 month after ACDF. Although the incidence of aspiration or penetration in VFSS after ACDF was high, no patient had aspiration pneumonia, which may be because of the intact neurological swallowing mechanism. The typical pattern of dysphagia after ACDF included vallecular and pyriform sinuses filled with postswallow residue, which may result from soft tissue edema and weak constriction of pharyngeal muscles after ACDF.

Abstract
BACKGROUND The incidence rate of surgical treatment of cervical degenerative diseases (CDD) has increased in the USA and a large geographic variation has been shown. Little is known about such rates in Scandinavia and Europe. The aim of this population-based study was to (1) investigate annual incidence rates of operations performed in Norway, (2) to compare trends and variations in rates for surgical indications with and without myelopathy, and (3) to compare variations in the use of surgery between residential areas. METHODS Patients operated for CDD and recorded in the Norwegian Patient Registry from 2008 to 2014 were evaluated according to residential areas (resident county and Regional Health Authority (RHA) area), age, gender, treating hospital, and whether myelopathy was present or not. Surgical rates were adjusted for age and gender. Data from private health care were also included. RESULTS The annual surgical rates increased by 74.1 % from 2008 to 2014 (12.5/100,000 inhabitants). The largest increase was for surgical treatment of radiculopathy, 86.5 %. Surgical rates for CDD varied in 2014 with a ratio of 1.5 between the highest and lowest RHA and with a ratio of 2.5 between the different residential counties within one RHA. The treatment rates for myelopathy were relatively stable over time, but showed an increase of 2.1/100,000 (44.6 %) from 2013 to 2014. CONCLUSIONS Our study shows that the rate of surgical treatment for radiculopathy due to CDD has increased substantially from 2008 to 2014 for all RHAs in Norway. The incidence rate for surgical treatment of myelopathy was more stable. An unexplained and moderate geographic variation was found.

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.

Quality analysis of anterior cervical discectomy and fusion in the outpatient versus inpatient setting: analysis of 7288 patients from the NSQIP database. Neurosurg Focus 2015; 39:E9.

Abstract
OBJECT
In an era of escalating health care cost and universal pressure of improving 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 is rapidly increasing with an expanding aging population. While ASCs offer cost advantages for ACDF, there is a scarcity of evidence that ASCs allow for equivalent quality and thus superior health care value. Therefore, the authors analyzed a nationwide, prospective quality improvement registry (National Surgical Quality Improvement Program [NSQIP]) to compare the quality of ACDF surgery performed in the outpatient ASC versus the inpatient hospital setting.
METHODS
Patients undergoing ACDF (2005-2011) were identified from the NSQIP database based on the primary Current Procedural Terminology codes. Patients were divided into 2 cohorts (outpatient vs inpatient) based on the acute care setting documented in the NSQIP database. All 30-day surgical morbidity and mortality rates were compared between the 2 groups. Propensity score matching and multivariate logistic regression analysis were used to adjust for confounding factors and to identify the independent association of outpatient ACDF with perioperative outcomes and morbidity.
RESULTS
A total of 7288 ACDF cases were identified (inpatient = 6120, outpatient = 1168). Unadjusted rates of major morbidity (0.94% vs 4.5%, p < 0.001) and return to the operating room (OR) within 30 days (0.3% vs 2.0%, p < 0.001) were significantly lower in outpatient versus inpatient ACDF. After propensity matching 1442 cases (inpatient = 650, outpatient = 792) based on baseline 32 covariates, rates of major morbidity (1.4% vs 3.1%, p = 0.03), and return to the OR (0.34% vs 1.4%, p = 0.04) remained significantly lower after outpatient ACDF. Adjusted comparison using multivariate logistic regression demonstrated that ACDF performed in the outpatient setting had 58% lower odds of having a major morbidity and 80% lower odds of return to the OR within 30 days.
CONCLUSIONS
An analysis of a nationwide, prospective quality improvement registry representing more than 250 hospitals demonstrates that 1- to 2-level ACDF can be safely performed in the outpatient ambulatory surgery setting in patients who are appropriate candidates. In an effort to decrease cost of care, surgeons can safely consider performing ACDF in an ASC environment.

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.
