OBJECTIVEOutpatient 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.METHODSIn 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.RESULTSIn 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.CONCLUSIONSAnterior 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 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 &lt; .001), mortality (P &lt; .001), and hospitalization duration (P &lt; .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.

OBJECTIVE Methods of reducing complications in individuals electing to undergo anterior cervical discectomy and fusion (ACDF) rely upon understanding at-risk patient populations, among other factors. This study aims to investigate the interplay between social determinants of health (SDOH) and postoperative complication rates, length of stay, revision surgery, and rates of postoperative readmission at 30 and 90 days in individuals electing to have single-level ACDF. METHODS Using MARINER30, a database that contains claims information from all payers, patients were identified who underwent single-level ACDF between 2010 and 2019. Identification of patients experiencing disparities in 1 of 6 categories of SDOH was completed using ICD-9 and ICD-10 (International Classifications of Diseases, Ninth and Tenth Revisions) codes. The population was propensity matched into 2 cohorts based on comorbidity status: those with SDOH versus those without. RESULTS A total of 10,030 patients were analyzed; there were 5015 (50.0%) in each cohort. The rates of any postoperative complication (12.0% vs 4.6%, p < 0.001); pseudarthrosis (3.4% vs 2.6%, p = 0.017); instrumentation removal (1.8% vs 1.2%, p = 0.033); length of stay (2.54 ± 5.9 days vs 2.08 ± 5.07 days, p < 0.001 [mean ± SD]); and revision surgery (9.7% vs 4.2%, p < 0.001) were higher in the SDOH group compared to patients without SDOH, respectively. Patients with any SDOH had higher odds of perioperative complications (OR 2.8, 95% CI 2.43–3.33), pseudarthrosis (OR 1.3, 95% CI 1.06–1.68), revision surgery (OR 2.4, 95% CI 2.04–2.85), and instrumentation removal (OR 1.4, 95% CI 1.04–2.00). CONCLUSIONS In patients who underwent single-level ACDF, there is an association between SDOH and higher complication rates, longer stay, increased need for instrumentation removal, and likelihood of revision surgery.

Abstract INTRODUCTION Anterior cervical discectomy and fusion (ACDF) is one of the most prevalent surgical procedures and is used to treat several cervical spinal pathologies, including herniated discs, degenerative disc disease, and spondylosis. With the increasing prevalence of ACDF procedures, this procedure has become an excellent target for clinical optimization. Indeed, in recent years, ACDF has become increasingly offered on an outpatient basis. To date, the incidence and dynamics of perioperative complications and safety surrounding outpatient ACDF remain poorly resolved. METHODS We systematically reviewed the literature for articles published by April 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 overall and specific complications between the inpatient and outpatient ACDF 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.

SummaryObjectives: To compare the complication rate between open reduction and internal fixation (ORIF) and external skeletal fixation (ESF) for feline diaphyseal tibial fractures.Methods: In a retrospective study spanning a 10 year period, 57 feline tibial fractures stabilized via ESF or ORIF were included for analysis and complication rates were compared between the two methods.Results: In the overall study population, 23 (40.4%) cases suffered complications (9 major, 20 minor, 6 with both major and minor). All of the major complications occurred in the ESF group. Complications were more common in cats with ESF (50.0%) while only one (7.7%) of the ORIF cases suffered complications (OR 12.0 [CI: 2.09; 228.10], p = 0.02). Use of postoperative antibiotic medications was identified as a confounder. After adjusting for confounding, stabilization using ESF remained associated with a higher risk of complications (OR = 13.71 [CI: 2.18; 274.25], p = 0.02). Cats with ESF had a longer duration of follow-up (15.6 weeks; 95% CI: 13.0; 18.3) compared to ORIF (9.5 weeks; 95% CI: 6.4; 12.7) (p = 0.003), and a higher number of revisits (mean 3.0; 95% CI: 2.4; 3.6) than the ORIF group (mean 1.6; 95% CI: 0.9; 2.3) (p = 0.002).Clinical significance: This study demonstrates a significant difference in complication rates between the methods of stabilization, with ESF resulting in a significantly higher complication rate compared to ORIF. Based on these results, it may be prudent to select ORIF for stabilization of feline tibial fractures wherever practical.

Background: Anterior cervical discectomy and fusion (ACDF) is a commonly performed procedure to address cervical myeloradiculopathy. However, 30-day outcomes after additional plating/instrumentation are not very clear. Methods: The authors reviewed The National Surgical Quality Improvement Program database to identify all elective ACDF cases with or without instrumentation for patients having cervical spondylosis with or without myelopathy from 2011 to 2013 using current procedural terminology and International Classification of Disease-9 codes. We identified 2352 cases and subdivided these into two cohorts based on instrumentation procedures (588 cases without instrumentation and 1764 cases with instrumentation). Baseline differences in two cohorts were adjusted by propensity score matching analysis, yielding well-matched 583 pairs. Results: Following propensity matching, the authors observed no significant difference in 30-day complication rates (prematch, 2.4% vs. 2.4%; and postmatch, 2.4% vs. 1.7%), readmission (prematch, 4.1% vs. 3.2%; and postmatch, 3.9% vs. 3.3%), and reoperation (prematch 0.9% vs. 1.8%; and postmatch 0.9% vs. 1.5%). Conclusion: Our results demonstrate similar 30-day outcomes in both cohorts and suggest that instrumentation can be safely implemented in the setting of ACDF.

Objective:Specialization is generally independently associated with improved outcomes for most types of surgery. This is the first study comparing the immediate success of outpatient lumbar microdiscectomy with respect to acute complication and conversion to inpatient rate. Long term pain relief is not examined in this study.Methods:Two separate prospective databases (one belonging to a neurosurgeon and brain tumor specialist, not specializing in spine (NS) and one belonging to four spine surgeons (SS)) were retrospectively reviewed. All acute complications as well as admission data of patients scheduled for outpatient lumbar microdiscectomy were extracted.Results:In total, 269 patients were in the NS group and 137 patients were in the SS group. The NS group averaged 24 cases per year while the SS group averaged 50 cases per year. Chi-square tests revealed no difference in acute complication rate [NS(6.7%), SS(7.3%)] (p>0.5) and admission rate [NS(4.1%), SS(5.8%)] (p=0.4) while the SS group had a significantly higher proportion of patients undergoing repeat microdiscectomy [NS(4.1%), SS(37.2%)] (p<0.0001). Excluding revision operations, there was no statistically significant difference in acute complication [NS(5.4%), SS(1.2%)] (p=0.09) and conversion to inpatient [NS(4.3%), SS(4.6%)] (p>0.5) rate. The combined acute complication and conversion to inpatient rate was 6.9% and 4.7% respectively.Conclusion:Based on this limited study, outpatient lumbar microdiscectomy can be apparently performed safely with similar immediate complication rates by both non-spine specialized neurosurgeons and spine surgeons, even though the trend favored the latter group for both outcome measures.

OBJECTIVEPituitary adenomas are benign, slow-growing tumors that cause symptoms either through mass effect or hormone overproduction. The decision to operate on a healthy young person is relatively straightforward. In the elderly population, however, the risks of complications may increase, rendering the decision more complex. Few studies have documented the risks of surgery using the endonasal endoscopic approach in a large number of elderly patients. The purpose of this study was to audit a single center's data regarding outcomes of purely endoscopic endonasal transsphenoidal resection of pituitary adenomas in elderly patients and to compare them to the current literature.METHODSA retrospective review of a prospectively acquired database of all endonasal endoscopic surgeries done by the senior authors was queried for patients aged 60–69 years and for those aged 70 years or older. Demographic and radiographic preoperative data were reviewed. Outcomes with respect to extent of resection and complications were examined and compared with appropriate statistical tests.RESULTSA total of 135 patents were identified (81 aged 60–69 years and 54 aged 70 years or older [70+]). The average tumor diameter was slightly larger for the patients in the 70+ age group (mean [SD] 25.7 ± 9.2 mm) than for patients aged 60–69 years (23.1 ± 9.8 mm, p = 0.056). There was no significant difference in intraoperative blood loss (p > 0.99), length of stay (p = 0.22), or duration of follow-up (p = 0.21) between the 2 groups. There was a 7.4% complication rate in patients aged 60–69 years (3 nasal and 3 medical complications) and an 18.5% complication rate in patients older than 70 years (4 cranial, 3 nasal, 1 visual, and 2 medical complications; p = 0.05 overall and 0.013 for cranial complications). Cranial complications in the 70+ age category included 2 postoperative hematomas, 1 pseudoaneurysm formation, and 1 case of symptomatic subdural hygromas.CONCLUSIONSEndonasal endoscopic surgery in elderly patients is safe, but there is a graded increase in complication rates with increasing age. The decision to operate on an asymptomatic or mildly symptomatic patient in these age groups should take this increasing complication rate into account. The use of a lumbar drain or lumbar punctures should be weighed against the risk of subdural hematoma in patients with preexisting atrophy.

Background: Pyelonephritis is a urinary tract infection that ascends to involve the kidneys. It can also occur as an infection secondary to bacteremia. Some pathogens that commonly cause pyelonephritis are E. coli, enterobacteriaceae, staphylococci, and pseudomonas. The initial patient presentation usually involves fever, chills, nausea, vomiting, costovertebral angle tenderness, and flank pain. Other cystitis symptoms such as dysuria, increased urinary frequency, malodorous urine, and hematuria may or may not be present. Symptoms of pyelonephritis with bacteriuria are sufficient for the diagnosis of pyelonephritis. Aim: The aim of this study was to investigate a potential link between Type II Diabetes Mellitus and pyelonephritis. Methods: In this retrospective study, hospitalized patients during the study period were reviewed. Variables examined were sex, age, and length of stay. Patients were excluded if they had known urogenital abnormalities, indwelling catheters (Foley, nephrostomy, suprapubic, or who regularly perform clean intermittent catheterization), were pregnant, or were on dialysis. Results: Of 333 patients analyzed, diabetics had a longer length of stay then non-diabetics (4.49 vs 3.67 days respectively; p=0.0041) and females were significantly younger than men in hospitalized patients for pyelonephritis were (50.0 vs 63.5 years; p=<0.0001). Further, it was found that diabetics were significantly older than nondiabetics were (60.4 vs 47.3; p=<0.0001) and more diabetics getting admitted with pyelonephritis were men vs women (59.32% vs 35.27%; p=0.0007). Conclusion: Results of the study were significant in showing that of all pyelonephritis-hospitalized patients on average the length of stay was longer for diabetics and it demonstrated that female patients with pyelonephritis are significantly younger than male patients hospitalized with pyelonephritis. Of note, there was no significant difference in the length of stay for diabetic patients based on their treatment modality (diet controlled vs. oral medications vs. insulin dependent vs. combined). The study also showed that diabetics getting admitted for pyelonephritis are more men and older in age compared to the nondiabetics.
