Abstract
INTRODUCTION Rapid recovery pathways (RRP) for adolescent idiopathic scoliosis patients undergoing posterior spinal instrumentation and fusion (PSIF) have been shown to be successful in reducing hospital length of stay (LOS). Although the majority of patients are discharged within 3 days, some patients require longer hospital admission. Previous studies in the United States have identified predictors of prolonged LOS for this patient population. The goal of this project was to determine if these predictors are the same for Canadian scoliosis patients and to identify those features which are different under this single-payer system. METHODS A RRP for scoliosis surgery was implemented in March 2015 at a single, tertiary referral children's hospital in Canada. Previously identified features, along with numerous other patient factors, were collected. Spearman correlations were used to determine the factors most associated with hospital LOS and those factors were used in a multivariable regression model. RESULTS A total of 161 patients were included in the analysis. Of the previously identified patient factors, only receiving a peri-operative transfusion was found to be significant (ρ = 0.24; p = 0.002). None of the other pre-identified variables were found to be significantly correlated with LOS. Variables not previously examined that were found to be significantly correlated with hospital LOS included ASA status (ρ = 0.19, p = 0.046), fusion involving both the thoracic and lumbar spine (ρ = 0.18, p = 0.025), and receiving celecoxib on post-operative day 1 (ρ = - 0.16; p = 0.038). The features that had the greatest association with LOS through multivariable regression was receiving a blood transfusion (B = 0.48; 95%CI 0.096-0.89; p = 0.017). CONCLUSIONS In this study, we found that many of the features found to be significantly correlated with prolonged hospital LOS in the United States are not transferable to the Canadian healthcare system. This is important for the Canadian, and other surgeons in a single-payer system, in order to identify pre-operative or immediate post-operative factors that may extend patient LOS following PSIF and plan resources accordingly.

Transdiscal instrumentation in single-level lumbosacral fusion for high-grade isthmic pediatric spondylolisthesis: Technical note and review of the literature. Neurochirurgie 2023; 69:101416. [PMID: 36750163 DOI: 10.1016/j.neuchi.2023.101416] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Revised: 01/23/2023] [Accepted: 01/25/2023] [Indexed: 02/07/2023]
Abstract
Pediatric spondylolisthesis is a common cause of back pain in children, typically managed conservatively with bracing and non-steroidal anti-inflammatory drugs. When posterolateral fusion is performed for refractory pain, pseudarthrosis and implant failure may occur, necessitating reoperation. To improve patient outcomes, there is a need for alternative surgical techniques to effectively manage high-grade isthmic slips. Here, the authors report the case of a child with Meyerding grade III anterolisthesis of L5 on S1 who was treated with a single-level, instrumented fusion using bilateral S1-L5 transdiscal screws, supported with L5-S1 posterolateral instrumentation and arthrodesis. Postoperatively, there was improvement in the patient's symptoms with good clinical and radiographic outcomes. The patient continues to be symptom free with radiographic evidence of hardware stability and bony fusion across the segment. The authors detail a novel surgical technique in children as well as a review of lumbosacral transdiscal screw fixation. Further evidence is required to definitively establish the safety, outcomes, and biomechanical strength of this technique.

Operative differences for posterior spinal fusion after vertebral body tethering: Are we fusing more levels in the end? EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2023; 32:625-633. [PMID: 36542164 DOI: 10.1007/s00586-022-07450-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/13/2022] [Revised: 09/09/2022] [Accepted: 11/04/2022] [Indexed: 12/24/2022]
Abstract
PURPOSE Little is known about the perioperative characteristics associated with a posterior spinal fusion (PSF) in adolescent idiopathic scoliosis patients previously treated with vertebral body tethering (VBT). We aimed to determine if operative time, estimated blood loss, postoperative length of stay, instrumentation type, and implant density differed in patients that received a PSF (i.e., PSF-Only) or a PSF following a failed VBT (i.e., PSF-VBT). METHODS We retrospectively assessed matched cohort data (PSF-VBT = 22; PSF-Only = 22) from two multi-center registries. We obtained: (1) operative time, (2) estimated blood loss, (3) postoperative length of stay, (4) instrumentation type, and (5) implant density. Theoretical fusion levels prior to the index procedure were obtained for PSF-VBT and compared to the actual levels fused. RESULTS We observed no difference in operative time, estimated blood loss, or postoperative length of stay. Instrumentation type was all-screw in PSF-Only and varied in PSF-VBT with nearly 25% of patients exhibiting a hybrid construct. There was no added benefit to removing anterior instrumentation prior to fusion; however, implant density was higher in PSF-Only (1.9 ± 0.2) than when compared to PSF-VBT (1.7 ± 0.3). An additional two levels were fused in 50% of PSF-VBT patients, most of which were added to the distal end of the construct. CONCLUSIONS We found that operative time, estimated blood loss, and postoperative length of stay were similar in both cohorts; however, the length of the fusion construct in PSF-VBT is likely to be two levels longer when a failed VBT is converted to a PSF.

Complications following posterior spinal fusion for adolescent idiopathic scoliosis: a retrospective cohort study using the modified Clavien-Dindo-Sink system. Spine Deform 2022; 10:607-614. [PMID: 35112274 DOI: 10.1007/s43390-021-00468-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Accepted: 12/18/2021] [Indexed: 10/19/2022]
Abstract
PURPOSE Published complication rates after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS) range from 1 to 22%. Complications are often minor and may be underestimated in registries. This study describes complications of PSF for AIS, classifies them according to a Clavien-Dindo-Sink (CDS) system, and investigates risk factors for occurrence of a complication. METHODS This retrospective cohort study at two academic centers included all AIS patients aged 10-18 who underwent primary PSF 4/2014-12/2019. Data included demographics, comorbidities, curve magnitude, Lenke classification, levels osteotomized/fused, implant density, 90-day emergency department visits, readmissions, reoperations, and complications as defined by Harms Study Group. RESULTS Among 424 patients, mean age was 14.7, mean BMI 22, 77% were female, and 57% had no comorbidities. There were 270 complications (0.64 per patient); 198 patients (47%) had ≥ 1 complication; and 63 patients (15%) had CDS grade ≥ II complications (deviation from standard postoperative course). Complications not related to persistent pain occurred in 103 patients (24%). Ninety-three percent of complications did not require readmission or reoperation (CDS I-II). Within 90 days, 8% presented to an ED, 2% required readmission, and 2% required reoperation. Common complications were back pain > 6 weeks postoperatively (26%), surgical site complications (7%), and ileus/prolonged constipation (3%). Risk factors for experiencing any complication were BMI ≥ 34 (OR 3.44) and Lenke 6 curve (OR 1.95). CONCLUSION One in four AIS patients experiences a complication not related to persistent pain after primary PSF, higher than rates published from self-reported registries. Obesity and Lenke 6 curve may increase risk. While most do not require readmission or surgery, 15% of patients have their postoperative course altered by complications. LEVEL OF EVIDENCE III-retrospective cohort study.

World Neurosurg 2021; 161:e18-e24. [PMID: 34688933 DOI: 10.1016/j.wneu.2021.10.125] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2021] [Revised: 10/14/2021] [Accepted: 10/15/2021] [Indexed: 10/20/2022]
Abstract
OBJECTIVE To determine the effects of preoperative hyponatremia on short-term postoperative complications and healthcare utilization (length of stay, readmissions) following anterior cervical fusion and discectomy (ACDF). METHODS Patients who underwent ACDF were identified in the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database. Patients who had revision surgery, trauma, vertebral malignancy, or infection were excluded. Eunatremia was defined as sodium (Na) level between 135 and 145 mEq/L, whereas hyponatremia was defined as Na < 135 mEq/L. Preoperatively hyponatremic patients were matched 1:1 with eunatremic patients using propensity-score matching based upon age, gender, American Society of Anesthesiology (ASA) score, and baseline comorbidities. Minor adverse events included superficial infection, dehiscence, urinary tract infection, pneumonia, and renal insufficiency or failure. Serious adverse events included deep wound infection, reintubation, pulmonary embolism, cerebrovascular accident, cardiac arrest, deep vein thrombosis, sepsis, return to operating room, and death within 30 days. Complications were analyzed using bivariate and logistic analysis with significance set at p<0.05. RESULTS Of the 9,094 patients undergoing ACDF, 3.64% (331 patients) were preoperatively hyponatremic. Preoperative hyponatremia was an independent risk factor for postoperative pneumonia following ACDF (OR=4.47; p=0.020) as well as extended length of hospital stay greater than one standard deviation above the mean (OR=1.71; p=0.042). Preoperative hyponatremia was an independent risk factor for having a serious adverse event (OR=2.40; p=0.005), as well as any adverse event (OR=2.44; p=0.009). CONCLUSION Preoperative hyponatremia is an independent risk factor for pneumonia and prolonged length of stay following ACDF.

Abstract
OBJECTIVE The aim of this study was to determine the impact of preoperative pulmonary risk factors (PRFS) on surgical outcomes after posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS). METHODS A retrospective cohort study was performed using the American College of Surgeons National Surgical Quality Improvement Program-Pediatric database from 2016 to 2018. All pediatric patients with AIS undergoing PSF were identified. Patients were then categorized by whether they had recorded baseline PRF or no-PRF. Patient demographics, comorbidities, intraoperative variables, complications, length of stay, discharge disposition, and readmission rate were assessed. RESULTS A total of 4929 patients were identified, of whom 280 (5.7%) had baseline PRF. Compared with the no-PRF cohort, the PRF cohort had higher rates of complications (PRF, 4.3% vs. no-PRF, 2.2%; P = 0.03) and longer hospital stays (PRF, 4.6 ± 4.3 days vs. no-PRF, 3.8 ± 2.3 days; P < 0.001), yet, discharge disposition was similar between cohorts (P = 0.70). Rates of 30-day unplanned readmission were significantly higher in the PRF cohort (PRF, 6.3% vs. no-PRF, 2.7%; P = 0.009), yet, days to readmission (P = 0.76) and rates of 30-day reoperation (P = 0.16) were similar between cohorts. On multivariate analysis, PRF was found to be a significant independent risk factor for longer hospital stays (risk ratio, 0.74; 95% confidence interval, 0.44-1.04; P < 0.001) but not postoperative complication or 30-day unplanned readmission. CONCLUSIONS Our study showed that PRF may be a risk factor for slightly longer hospital stays without higher rates of complication or unplanned readmission for patients with AIS undergoing PSF and thus should not preclude surgical management.

Is it feasible to implement a rapid recovery pathway for adolescent idiopathic scoliosis patients undergoing posterior spinal instrumentation and fusion in a single-payer universal health care system? Spine Deform 2020; 8:1223-1229. [PMID: 32488767 DOI: 10.1007/s43390-020-00146-w] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2020] [Accepted: 05/19/2020] [Indexed: 12/20/2022]
Abstract
PURPOSE The purpose of this project was to determine if it is feasible to implement a rapid recovery pathway (RRP) for the surgical treatment of adolescent idiopathic scoliosis (AIS) within a single-payer universal healthcare system while simultaneously decreasing length of stay (LOS) without increasing post-operative complications. METHODS A retrospective analysis was completed for all patients who underwent posterior spinal fusion for AIS at a tertiary children's hospital in Canada between March 2010 and February 2019, with date of implementation of the RRP being March 1st, 2015. Patient demographic information was collected along with a variety of outcome variables including: LOS, wound complication, infection, 30-day return to the OR, 30-day emergency department visit, and 30-day hospital readmission. An interrupted time series analysis was utilized to determine if any benefits were associated with the implementation of the RRP. RESULTS A total of 244 patients were identified, with 113 patients in the conventional pathway and 131 in the RRP. No significant differences in demographic features or post-operative complications were found between the two cohorts (p > 0.05). Using a robust linear time series model, LOS was found to be significantly shorter in the RRP group, with the average LOS being 5.2 [95% IQR 4.3-6.1] days in the conventional group and 3.4 [95% IQR 3.3-3.5] days in the RRP group (p < 0.05). CONCLUSION This study shows that it is possible to implement a RRP for the surgical treatment of AIS within a single-payer universal healthcare system. Use of the pathway can effectively reduce hospital LOS without increasing the risk of developing a post-operative complication. This has the upside potential to reduce healthcare and family costs. LEVEL OF EVIDENCE Therapeutic III.
