[PMID: 37794490 PMCID: PMC10548749 DOI: 10.1186/s13018-023-04227-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Accepted: 09/22/2023] [Indexed: 10/06/2023] Open
Abstract
OBJECTIVE The literature currently available on the characteristics of patients who require intensive care unit (ICU) admission after correction surgery for adult spinal deformity is lacking; this study aimed to identify risk factors for postoperative ICU admission following correction surgery for adult spinal deformity. METHODS A retrospective review of patients who underwent primary posterior-based spinal fusion from 2015 to 2023 was performed. According to the ward they returned to, patients were further divided into an ICU group and a non-ICU group. Univariate and multivariate analyses were performed to evaluate preoperative and perioperative parameters to identify independent risk factors for postoperative ICU admission in adult spinal deformity patients. RESULTS A total of 274 patients were included, including 115 males (41.97%) and 159 females (58.03%). The mean age of the patients was 32.00 ± 11.16 years (19-77 years). Following adjusted analysis, the preoperative and perioperative factors that were independently associated with ICU admission were age, body mass index ≥ 28 kg/m2, neuromuscular spinal deformity, respiratory disease, grade III-IV American Society of Anesthesiologists (ASA) classification, a scoliosis Cobb angle ≥ 90°, a kyphosis Cobb angle ≥ 90°, and ≥ 12 fused segments. Compared with the non-ICU group, the ICU group had a higher incidence of complications, a longer hospital stay, and higher medical costs (P < 0.05). CONCLUSION This study identified independent risk factors associated with postoperative ICU admission in adult spinal deformity patients; and explored relative measures to decrease or avoid the risk of postoperative ICU admission. Surgeons could use these data to develop and plan appropriate perioperative care processes in advance and provide consultation for family members before surgery.

Abstract
BACKGROUNDS New methods such as machine learning could provide accurate predictions with little statistical assumptions. We seek to develop prediction model of pediatric surgical complications based on pediatric National Surgical Quality Improvement Program(NSQIP). METHODS All 2012-2018 pediatric-NSQIP procedures were reviewed. Primary outcome was defined as 30-day post-operative morbidity/mortality. Morbidity was further classified as any, major and minor. Models were developed using 2012-2017 data. 2018 data was used as independent performance evaluation. RESULTS 431,148 patients were included in the 2012-2017 training and 108,604 were included in the 2018 testing set. Our prediction models had high performance in mortality prediction at 0.94 AUC in testing set. Our models outperformed ACS-NSQIP Calculator in all categories for morbidity (0.90 AUC for major, 0.86 AUC for any, 0.69 AUC in minor complications). CONCLUSIONS We developed a high-performing pediatric surgical risk prediction model. This powerful tool could potentially be used to improve the surgical care quality.

Perioperative Care of Children with Severe Neurological Impairment and Neuromuscular Scoliosis- A Practical Pathway to Optimize Peri-Operative Health and Guide Decision Making. J Clin Med 2022; 11:jcm11226769. [PMID: 36431246 PMCID: PMC9696380 DOI: 10.3390/jcm11226769] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 11/07/2022] [Accepted: 11/14/2022] [Indexed: 11/17/2022] Open
Abstract
Neuromuscular scoliosis is a common feature in children with severe neurological impairment (SNI), including those with severe cerebral palsy. Surgical correction of scoliosis is the mainstay of treatment. This group of patients also have associated medical complexity. The complication rates post-surgery are high, although, for many, they are worth the risk. There are currently no published practice guidelines or care pathways for children with SNI who are undergoing scoliosis corrective surgery. In response to the high uptake of this surgery, coupled with the expected complication rates, our hospital established a perioperative clinic. The purpose of this paper is to describe our perioperative approach. This clinic has developed into a service beyond perioperative care and, with the collaborative meeting, enables shared decision-making to identify the right candidate for surgery. The process involves surgical expertise, understanding the family and child at the centre, and optimisation of medical care pre- and post-surgery. In this paper, we describe the process in a step-by-step manner. We provide clinical vignettes, as well as the proformas that we use, and we highlight the benefits of the team-based process.

Abstract
BACKGROUND Risk-adjustment is a key feature of the American College of Surgeons National Surgical Quality Improvement Program-Pediatric (NSQIP-Ped). Risk-adjusted model variables require meticulous collection and periodic assessment. This study presents a method for eliminating superfluous variables using the congenital malformation (CM) predictor variable as an example. METHODS This retrospective cohort study used NSQIP-Ped data from January 1st to December 31st, 2019 from 141 hospitals to compare six risk-adjusted mortality and morbidity outcome models with and without CM as a predictor. Model performance was compared using C-index and Hosmer-Lemeshow (HL) statistics. Hospital-level performance was assessed by comparing changes in outlier statuses, adjusted quartile ranks, and overall hospital performance statuses between models with and without CM inclusion. Lastly, Pearson correlation analysis was performed on log-transformed ORs between models. RESULTS Model performance was similar with removal of CM as a predictor. The difference between C-index statistics was minimal (≤ 0.002). Graphical representations of model HL-statistics with and without CM showed considerable overlap and only one model attained significance, indicating minimally decreased performance (P = 0.058 with CM; P = 0.044 without CM). Regarding hospital-level performance, minimal changes in the number and list of hospitals assigned to each outlier status, adjusted quartile rank, and overall hospital performance status were observed when CM was removed. Strong correlation between log-transformed ORs was observed (r ≥ 0.993). CONCLUSIONS Removal of CM from NSQIP-Ped has minimal effect on risk-adjusted outcome modelling. Similar efforts may help balance optimal data collection burdens without sacrificing highly valued risk-adjustment in the future. LEVEL OF EVIDENCE Level II prognosis study.

THE LANCET CHILD & ADOLESCENT HEALTH 2021; 5:739-750. [PMID: 34370979 DOI: 10.1016/s2352-4642(21)00161-9] [Citation(s) in RCA: 30] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 11/17/2020] [Revised: 05/11/2021] [Accepted: 05/12/2021] [Indexed: 11/17/2022]
Abstract
In an era of tremendous medical advancements, it is important to characterise and address inequities in the provision of health care and in outcomes. There is a large body of evidence describing such disparities by race or ethnicity and socioeconomic position in critically ill adults; however, this important issue has received less attention in children and adolescents (aged ≤21 years). This Review presents a summary of the available evidence on disparities in outcomes in paediatric critical illness in the USA as a result of racism and socioeconomic privilege. The majority of evidence of racial and socioeconomic disparities in paediatric critical care originates from the USA and is retrospective, with only one prospective intervention-based study. Although there is mixed evidence of disparities by race or ethnicity and socioeconomic position in general paediatric intensive care unit admissions and outcomes in the USA, there are striking trends within some disease processes. Notably, there is evidence of disparities in management and outcomes for out-of-hospital cardiac arrest, asthma, severe trauma, sepsis, and oncology, and in families' perceptions of care. Furthermore, there is clear evidence that critical care research is limited by under-enrolment of participants from minority race or ethnicity groups. We advocate for rigorous research standards and increases in the recruitment and enrolment of a diverse range of participants in paediatric critical care research to better understand the disparities observed, including the effects of racism and poverty. A clearer understanding of when, where, and how such disparities affect patients will better enable the development of effective strategies to inform practice, interventions, and policy.

Akesen S. Predictive factors for postoperative ıntensive care unit admission in pediatric patients undergoing scoliosis correction surgery. Am J Transl Res 2021; 13:5386-5394. [PMID: 34150135 PMCID: PMC8205743] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Accepted: 03/04/2021] [Indexed: 06/12/2023]
Abstract
OBJECTIVE Postoperative intensive care unit (ICU) admission might be required in adolescent patients following posterior fusion and instrumentation surgery for the treatment of scoliosis. We aimed to evaluate the predictive factors for mechanical ventilation and the characteristics of the patients who required an ICU stay following spinal surgery. METHODS We retrospectively reviewed the records of 85 children undergoing primary scoliosis surgery at a university-affiliated general hospital from January 2010 and June 2020 by the same spinal surgeon. The demographic data, pre- and peritoperative variables were collected and recorded. All patients underwent surgery with a combined anesthesia protocol of fentanyl and remifentanil. RESULTS There were 31 males (36.5%) and 54 females (63.5%). In the postoperative period, 13 patients (15.3%) were admitted to the ICU, and six of them required mechanical ventilation. Among these, three patients (50%) were extubated within the postoperative 0-12 hours, two (33.3%) within postoperative 12-24 hours, and one (16.7) after postoperative 24 hours. The major complications included acidosis (4.7%), hemodynamic instability (1.2%), hypercapnia (1.2%), hypoxemia (1.2%), and delayed extubation (1.2%). CONCLUSIONS A smaller bodyweight percentile, neuromuscular etiology, abnormal findings in preoperative chest X-ray, additional comorbidities, and preoperative estimated risk for postoperative mechanical ventilation were among the risk factors for postoperative ICU stay. The age, height, weight, degree of the curvature, and the number of operated segments did not have an association with the postoperative outcomes.

Improving Safety and Efficacy in the Surgical Management of Low-tone Neuromuscular Scoliosis: Integrated Approach With a 2-attending Surgeon Operative Team and Modified Anesthesia Protocol. J Pediatr Orthop 2021; 41:e1-e6. [PMID: 32804863 DOI: 10.1097/bpo.0000000000001658] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/07/2023]
Abstract
BACKGROUND Substantially increased operative time and amount of bleeding may complicate the course of surgical treatment in neuromuscular scoliosis. A well-organized team approach is required to reduce morbidity. The aim of this study is to review our early, short-term surgical outcomes with our new integrated approach that includes a 2-attending surgeon team and modifications in the anesthesia protocol in low-tone neuromuscular scoliosis and compare with a matched cohort of our historic patients. METHODS We retrospectively reviewed our patients with (1) neuromuscular scoliosis with collapsing spine deformity, (2) low-tone neuromuscular etiology, (3) multilevel posterior column osteotomies with posterior all pedicle screw spinal fusion, and (4) more than 1-year follow-up. Patients were grouped into 2: group 1 consisted of patients managed with the integrated surgical team approach, group 2 included the matched historic patients. RESULTS There were 16 patients in group 1 and 17 patients in group 2. There was no significant difference between the groups regarding age, sex, body mass index, number of levels fused, major coronal deformity magnitude, pelvic obliquity, number of posterior column osteotomies, or amount of deformity correction. However, significantly shorter operative time (241 vs. 297 min, P=0.006), less intraoperative bleeding (1082 vs. 1852 mL, P=0.001), less intraoperative blood transfusion (2.1 vs. 3.1 U, P=0.028), less postoperative intensive care unit admission (23% vs. 100%, P=0.001), and shorter hospital stay (4.7 vs. 5.9 d, P=0.013) were observed in group 1. CONCLUSIONS Our results indicate that spinal deformity surgery in patients with underlying low-tone neuromuscular disease may not be as intimidating as previously thought. Our surgical team approach integrating a 2-attending surgeon operative team, a new anesthetic protocol that includes a modification of perioperative blood management is effective in reducing operative times, blood loss, transfusion rates, intensive care unit admission, and length of hospital stay. LEVELS OF EVIDENCE Level III-retrospective comparative study.
