Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE The objective of this study is to determine differences in outcomes in patients with adolescent idiopathic scoliosis undergoing spinal deformity correction surgery using a posterior spinal fusion (PSF) approach versus single and triple-incision minimally invasive surgery (MIS). SUMMARY OF BACKGROUND DATA MIS increased in popularity as surgeons' focus moved towards soft tissue preservation, but it carries technical demands and increased surgical time compared with PSF. PATIENTS AND METHODS Surgeries performed from 2016 to 2020 were included. Cohorts were formed based on surgical approach: PSF versus single long-incision MIS (SLIM) versus traditional MIS [3-incision MIS (3MIS)]. There were a total of 7 subanalyses. Demographic, radiographic, and perioperative data were collected for the 3 groups. Kruskal-Wallis and χ 2 tests were used for continuous and categorical variables, respectively. RESULTS Five hundred thirty-two patients met our inclusion criteria, 294 PSF, 179 3MIS, and 59 SLIM.Estimated blood loss (mL) ( P < 0.00001) and length of stay (LOS) ( P < 0.00001) was significantly higher in PSF than in SLIM and 3MIS. Surgical time was significantly higher in 3MIS than in PSF and SLIM ( P = 0.0012).Patients who underwent PSF had significantly lower postoperative T5 to T12 kyphosis ( P < 0.00001) and percentage kyphosis change ( P < 0.00001). Morphine equivalence was significantly higher in the PSF group during total hospital stay ( P = 0.0042).Patients who underwent SLIM and 3MIS were more likely to return to noncontact ( P = 0.0096) and contact sports ( P = 0.0095) within 6 months and reported lower pain scores ( P < 0.001) at 6 months postoperation. CONCLUSION SLIM has a similar operative time to PSF and is technically similar to PSF while maintaining the surgical and postoperative outcome advantages of 3MIS.

DeVries Z, Nucci N, Smit K, Tice A, Romeo J, Jarvis JG. Determining the factors associated with a prolonged length of stay for adolescent idiopathic scoliosis patients undergoing posterior spinal instrumentation and fusion in a single-payer health care system: are these factors different than those in the United States? Spine Deform 2024; 12:133-139. [PMID: 37672201 DOI: 10.1007/s43390-023-00750-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Accepted: 08/02/2023] [Indexed: 09/07/2023]
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.

Abstract
INTRODUCTION Bleeding and transfusion remain important concerns during surgical correction of scoliosis even when multiple conservative strategies, such as preoperative recombinant erythropoietin and/or antifibrinolytic agents, are used. The current work aimed to determine the impact of other potential risk factors, especially the volume of intraoperative fluid intake, on the perioperative risk of allogenic transfusion during surgical correction of adolescent idiopathic scoliosis. METHODS This prospective study included all cases of adolescent idiopathic scoliosis operated in a single center during 2 years (2018-2020). Predictors analyzed were as follows: body mass index, preoperative hemoglobin concentration, thoracoplasty, preoperative halo-gravity, volume of intraoperative crystalloid administration, use of esophageal Doppler (for goal-directed fluid therapy), and duration of surgery. Statistical analyses were performed using a multivariable logistic regression model. RESULTS Two hundred patients were included in the analysis. Multivariable analysis found: an increased volume of intraoperative crystalloid administration as a significant predictor of allogenic blood transfusion. Receiving operator characteristics analysis found the model exhibiting an area under the curve of 0.85 (95% confidence interval: 0.75-0.95). Optimizing stroke volume using esophageal Doppler was associated with a decrease in intraoperative crystalloid intake. CONCLUSION These results indicate a statistical association between the increase in crystalloid intake and the risk of allogenic blood transfusion during surgical correction of adolescent idiopathic scoliosis. Controlled studies are needed to address the causative relation between intraoperative fluid intake and the risk of allogenic transfusion.

Preliminary results in 68 patients. 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; 32:883-888. [PMID: 36653577 DOI: 10.1007/s00586-022-07512-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Revised: 11/10/2022] [Accepted: 12/17/2022] [Indexed: 01/20/2023]
Abstract
PURPOSE Patient blood management has been recently emphasized to avoid perioperative blood transfusion in AIS surgery. Hydroxyapatite charged collagen sponge (HCS) is a bone substitute material made of collagen and ceramized hydroxyapatite, with associated haemostatic properties. The goal of this study was to assess the impact of HCS in the perioperative blood loss in AIS surgery. METHODS After IRB approval, all AIS patients undergoing primary correction were prospectively included over a 15-month period. Patients receiving HCS at the end of the procedure were compared to a control group (matched for age, gender, and fusion levels) without any haemostatic agent or bone substitute. The same perioperative blood saving strategies were used in both groups. Two subfascial drains were used for 48 h in all patients. Perioperative blood loss and transfusion rates were analysed. RESULTS A total of 34 patients were included in each group. No difference in drainage volume was observed at day 1, but the reduction was statistically different at day 3 (1135 mL [800-1640] versus 930 [480-1510], p = 0.028, 0.63 ml/Kg/h [0.4-0.92] versus 0.46 [0.29-0.7], p = 0.042). Multivariate analysis found that the use of HCS was associated with a decrease in the postoperative blood loss (OR = 1.17 [1.10-1.25]). The transfusion rate was lower in the HCS group [0 (0% vs. 3(8.8%), p = 0.076)]. No infection occurred, and no complication was reported. CONCLUSION With 27% reduction in drain volume, hydroxyapatite charged collagen sponge can be considered as a blood salving strategy in AIS surgery. The role of the biomaterial in fusion rate still needs to be further assessed.

The Incidence and Risk Factors for Allogeneic Blood Transfusions in Pediatric Spine Surgery: National Data. Healthcare (Basel) 2023; 11:healthcare11040533. [PMID: 36833065 PMCID: PMC9956304 DOI: 10.3390/healthcare11040533] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 01/29/2023] [Accepted: 02/08/2023] [Indexed: 02/15/2023] Open
Abstract
(1) Background: Pediatric spinal surgery is a blood-intensive procedure. In order to introduce a rational blood management program, identifying the risk factors for transfusions is mandatory. (2) Methods: Data from the national database covering the period from January 2015 to July 2017 were analyzed. The available data included the demographics, characteristics of the surgeries performed, length of stay, and in-house mortality. (3) Results: The total number of patients used for the analysis was 2302. The primary diagnosis was a spinal deformity (88.75%). Most fusions were long, with four levels or more (89.57%). A total of 938 patients received a transfusion; thus, the transfusion rate was 40.75%. The present study identified several risk factors; the most significant was a number of levels fused greater than 4 (RR 5.51; CI95% 3.72-8.15; p < 0.0001), followed by the deformity as the main diagnosis (RR 2.69; CI95% 1.98-3.65; p < 0.0001). These were the two most significant factors increasing the odds of a transfusion. Other factors associated with an increased risk of transfusion were elective surgery, the female sex, and an anterior approach. The mean length of stay in days was 11.42 (SD 9.93); this was greater in the transfused group (14.20 vs. 9.50; p < 0.0001). (4) Conclusions: The rate of transfusions in pediatric spinal surgery remains high. A new patient blood management program is necessary to improve this situation.

Abstract
Surgical correction of paediatric spinal deformity is associated with risks, adverse events, and complications that must be preoperatively discussed with patients and their families to inform treatment decisions, expectations, and long-term outcomes. The incidence of complications varies in relation to the underlying aetiology of spinal deformity and surgical procedure. Intraoperative complications include bleeding, neurological injury, and those related to positioning. Postoperative complications include persistent pain, surgical site infection, venous thromboembolism, pulmonary complications, superior mesenteric artery syndrome, and also pseudarthrosis and implant failure, proximal junctional kyphosis, crankshaft phenomenon, and adding-on deformity, which may necessitate revision surgery. Interventions included in enhanced recovery after surgery protocols may reduce the incidence of complications. Complications must be diagnosed, investigated and managed expeditiously to prevent further deterioration and to ensure optimal outcomes. This review summarises the complications associated with paediatric spinal deformity surgery and their management.

Abstract
PURPOSE Describe the experience of one institution in modifying allogeneic blood transfusion protocols for AIS surgery in response to the results of ACS-NSQIP-PEDS comparative data in a retrospective cohort study. METHODS NSQIP data demonstrated that AIS patients at our hospital had a significantly greater risk of ALBT compared to similar institutions (OR 4.1). The ALBT protocol was then revised to initiate transfusion based on Hb/Hct level, clinical hypotension and/or discussion between surgeon and anesthesiologist. A retrospective analysis of perioperative ALBT and autologous cell salvage blood transfusion (CSBT) rates was performed for patients undergoing surgery before (Group A) and after (Group B) the implementation of the revised protocol. RESULTS Two hundred and ninety patients constituted the study cohort, with 92 patients in Group A and 198 in Group B. Average total blood transfusion (ALBT + CSBT) per patient was significantly lower for Group B than Group A (313 ml vs. 650 ml, p < 0.01). ALBT per patient of Group B was significantly lower than Group A (85 ml vs. 324 ml, p < 0.01). 48% of patients received ALBT in Group A compared to only 18% in Group B. CONCLUSION Recognition of excessive allogeneic transfusion rates in our institution through comparative data from the ACS-NSQIP-PEDS database resulted in the modification of transfusion parameters that led to a decrease in allogeneic transfusion rates for AIS patients. The current study highlights the value of a large, well-curated surgical database in optimizing clinical protocols and potentially improving overall surgical morbidity.

Abstract
BACKGROUND Children undergoing spinal fusion often receive blood products. The goal of this study was to develop a preoperative score to help physicians identify those who are at risk of allogeneic red blood cell (RBC) transfusion. STUDY DESIGN AND METHODS This retrospective study of children undergoing spinal fusion in the ACS-NSQIP Pediatric database (2016-2019) aimed at identifying risk factors associated with allogeneic RBC transfusion. Univariable logistic regression and multivariable logistic regression were performed using preoperative patient characteristics and aided in the creation of a simplified scoring system. RESULTS Out of 13,929 total patients, 2990 (21.5%) were transfused. We created a risk score based on 10 independent predictors of transfusion: age, sex, race, weight < 3rd percentile, American Society of Anesthesiologists physical status classification, cardiac risk factors, hematologic disease, preoperative anemia, deformity type, and number of spinal levels to be fused. Patients in both the training and testing cohorts were assigned a score ranging from 0 (lowest risk) to 21 (highest risk). The developed transfusion risk score showed 77% accuracy in distinguishing patients who did not receive a transfusion during or soon after surgery (AUROC 0.7736 [95% CI, 0.7619-0.7852]) in the training cohort and 77% accuracy (AUROC 0.7732 [95% CI, 0.7554-0.7910]) in the testing cohort. DISCUSSION Our score, based on routinely available preoperative data, accurately estimates the risk of allogeneic RBC transfusion in pediatric patients undergoing spinal fusion. Future studies will inform whether patient blood management interventions targeted to high-risk patients can help reduce the need for transfusion and improve outcomes.

Abstract
STUDY DESIGN Retrospective review of prospective case-control study. OBJECTIVE To compare minimally invasive scoliosis surgery (MIS) and posterior spinal fusion (PSF) in a large group of patients. SUMMARY OF BACKGROUND DATA MIS, has been shown to have benefits over standard PSF in adolescent idiopathic scoliosis (AIS). METHODS Radiographic, clinical, and operative review of a multi-institutional prospective database from 2013 to 2018. MIS patients with minimum 2-year XR follow up were compared with open PSF technique patients. RESULTS Four hundred eighty five patients were included; 192 MIS and 293 PSF. Preoperative Cobb (P = 0.231) and kyphosis were similar (P = 0.501). Cobb correction was comparable (P = 0.46), however percent improvement in thoracic kyphosis was significantly higher in MIS (P < 0.001). MIS had significantly lower blood loss (P < 0.001), transfusions (P < 0.001), fixation points (P < 0.001), opioid consumption (P = 0.001), and hospital stay (P < 0.001). Operative time was shorter (P = 0.001) and 30-day complications rate was similar (P = 0.81). CONCLUSION This is the largest study comparing the surgical outcomes of MIS and PSF. MIS patients benefit from increased kyphosis, fewer transfusion, lower opioid consumption, and shorter hospital stay with similar Cobb correction. Increased postoperative kyphosis is likely from muscle sparing dissection in MIS.Level of Evidence: 3.

Abstract
PURPOSE Many pediatric patients with severe scoliosis requiring surgery have baseline anemia. Pediatric scoliosis fusion surgery is associated with perioperative blood loss requiring transfusion. As such, many patients in this surgical population could benefit from a perioperative blood conservation program. METHODS Here we present a narrative review of perioperative blood conservation strategies for pediatric scoliosis surgery involving nurses, transfusion medicine physicians, anesthesiologists, surgeons, dieticians, perfusionists and neurophysiologists spanning the pre-, intra- and postoperative phases of care. RESULTS The review highlights how perioperative blood conservation strategies, have the potential to minimize exposures to exogenous blood products. Further, we describe a relevant example of blood conservation related to the care of a Jehovah's Witness patient undergoing staged scoliosis repair. Lastly, we outline areas which would benefit from clinical studies to further elucidate perioperative blood conservation interventions and their outcomes relevant to pediatric scoliosis surgery patients. CONCLUSION Interdisciplinary communication and meticulous blood conservation strategies are proving to be a means of reducing if not eliminating the need for allogeneic blood products for surgical correction of pediatric scoliosis.

Abstract
BACKGROUND CONTEXT The implementation of a dual attending surgeon strategy had improved perioperative outcomes of idiopathic scoliosis (IS) patients. Nevertheless, the learning curve of a dual attending surgeon practice in single-staged posterior spinal fusion (PSF) surgery has not been established. OBJECTIVE To evaluate the surgical learning curve of a dual attending surgeon strategy in IS patients. STUDY DESIGN Retrospective study. PATIENT SAMPLE 415 IS patients (Cobb angle <90°) who underwent PSF using a dual attending surgeon strategy OUTCOME MEASURES: Primary outcomes included operative time, total blood loss, allogenic blood transfusion requirement, length of hospital stay and perioperative complication rate. METHODS Regression analysis using Locally Weighted Scatterplot Smoothing (LOWESS) method was applied to create the best-fit-curve between case number versus operative time and total blood loss in identifying cut-off points for the learning curve. RESULTS The mean Cobb angle was 60.8±10.8°. Mean operative time was 134.4±32.1 minutes and mean total blood loss was 886.0±450.6 mL. The mean length of hospital stay was 3.0±1.6 days. The learning curves of a dual attending surgeon strategy in this study were established at the 115th case (operative time) and 196th case (total blood loss) respectively (p<.001). In comparison of cases before and after the cut-off points, mean operative time reduced significantly from 147.2±36.5 minutes to 129.5±28.9 minutes and mean total blood loss reduced significantly from 1015.1±506.6 mL to 770.4±357.3 mL (p<.001). No allogenic blood transfusion was required and there were 7 perioperative complications (n=7/415, 1.7%) recorded. CONCLUSION The learning curve of a dual surgeon strategy in single-staged PSF surgery based on operative time and total blood loss were established at 115th case and 196th case respectively (p<.001).

Safe and effective performance of pediatric spinal deformity surgery in patients unwilling to accept blood transfusion: a clinical study and review of literature. BMC Musculoskelet Disord 2021; 22:204. [PMID: 33607982 PMCID: PMC7896412 DOI: 10.1186/s12891-021-04081-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Accepted: 02/11/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Pediatric deformity surgery traditionally involves major blood loss. Patients refusing blood transfusion add extra clinical and medicolegal challenges; specifically the Jehovah's witnesses population. The objective of this study is to review the safety and effectiveness of blood conservation techniques in patients undergoing pediatric spine deformity surgery who refuse blood transfusion. METHODS After obtaining institutional review board approval, we retrospectively reviewed 20 consecutive patients who underwent spinal deformity surgery and refused blood transfusion at a single institution between 2014 and 2018. We collected pertinent preoperative, intraoperative and most recent clinical and radiological data with latest follow-up (minimum two-year follow-up). RESULTS Twenty patients (13 females) with a mean age of 14.1 years were identified. The type of scoliotic deformities were adolescent idiopathic (14), juvenile idiopathic (1), neuromuscular (3) and congenital (2). The major coronal Cobb angle was corrected from 55.4° to 11.2° (80% correction, p < 0.001) at the latest follow-up. A mean of 11.4 levels were fused and 5.6 levels of Pontes osteotomies were performed. One patient underwent L1 hemivertebra resection and three patients had fusion to pelvis. Estimated blood loss, percent estimated blood volume loss, and cell saver returned averaged 307.9 mL, 8.5%, and 80 mL, respectively. Average operative time was 214 min. The average drop in hemoglobin after surgery was 2.9 g/dL. The length of hospital stay averaged 5.1 days. There were no intraoperative complications. Three postoperative complications were identified, none related to their refusal of transfusion. One patient had in-hospital respiratory complication, one patient developed a late infection, and one patient developed asymptomatic radiographic distal junctional kyphosis. CONCLUSIONS Blood conservation techniques allow for safe and effective spine deformity surgery in pediatric patients refusing blood transfusion without major anesthetic or medical complications, when performed by an experienced multidisciplinary team. LEVEL OF EVIDENCE Level IV.

Dong Y, Tang N, Wang S, Zhang J, Zhao H. Risk factors for blood transfusion in adolescent patients with scoliosis undergoing scoliosis surgery: a study of 722 cases in a single center. BMC Musculoskelet Disord 2021; 22:13. [PMID: 33402158 PMCID: PMC7784304 DOI: 10.1186/s12891-020-03869-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/31/2020] [Accepted: 12/09/2020] [Indexed: 11/24/2022] Open
Abstract
Background To assess the risk factors for blood transfusion in a great number of adolescent cases with different types of scoliosis who received scoliosis surgery. Methods Data of patients who were diagnosed as scoliosis and received one-stage posterior correction and spinal fusion from January 2014 to December 2017 were prospectively collected and retrospectively analyzed. Patients’ demographic characteristics, segments of spinal fusion, Cobb angle of the major curve,osteotomy pattern, preoperative and postoperative levels of hemoglobin, and allogeneic blood transfusion (ABT) were recorded and analyzed. Results In this study, 722 cases with adolescent scoliosis were included, of whom 32.8% (237/722) received ABT. Risk factors included diagnosis: neurofibromatosis (OR = 5.592), syndromic (OR = 3.029),osteotomy: Ponte osteotomy (OR = 5.997), hemivertebrae resection (OR = 29.171), pedicle subtraction osteotomy (PSO)(OR = 8.712), vertebral column resection (VCR)(OR = 32.265);fusion segments (OR = 1.224) and intraoperative blood loss (OR = 1.004). In the subgroup analysis of cases with idiopathic scoliosis, Ponte osteotomy (OR = 6.086), length of segments of spinal fusion (OR = 1.293), and intraoperative blood loss (OR = 1.001) were found as risk factors for ABT. Results of receiver operating characteristic (ROC) curve analysis revealed that length of segments of spinal fusion equal to 11.5 vertebrae was the best cutoff value for cases with idiopathic scoliosis who did not receive osteotomy in both ABT group and non-ABT group. In the subgroup analysis of congenital scoliosis, Ponte osteotomy (OR = 5.087), hemivertebra resection (OR = 5.457), PSO (OR = 4.055), VCR (OR = 6.940), and intraoperative blood loss (OR = 1.004) were risk factors for ABT. Conclusions Method of diagnosis, osteotomy pattern, segments of spinal fusion, and intraoperative blood loss were risk factors for ABT in cases with adolescent scoliosis. In cases with idiopathic scoliosis, Ponte osteotomy and segments of spinal fusion longer than 11.5 vertebrae were risk factors for ABT. In cases with congenital scoliosis, osteotomy pattern was the main risk factor for ABT. Level of evidence Level III.
