Multicenter, retrospective series.To analyze the incidence, mode, and location of acute proximal junctional failures (APJFs) after surgical treatment adult spinal deformity.Early above deformity constructs are a serious clinical problem; however, incidence nature early APJFs remain unclear.A total 1218 consecutive surgeries across 10 centers were retrospectively reviewed to evaluate APJF, defined as any following within 28 weeks index procedure: minimum 15° post-operative increase in...
A retrospective analysis of a prospective, multicenter database.The aim this study was to evaluate the health impact symptomatic adult spinal deformity (SASD) by comparing Standard Form Version 2 (SF-36) scores for SASD with United States normative and chronic disease values.Recent data have identified radiographic parameters correlating poor health-related quality life SASD. Disability comparisons between patients diseases may provide further insight burden caused SASD.Consecutive patients,...
In Brief Study Design. Multicenter, retrospective, consecutive case series. Objective. This study aims to identify demographic and radiographical characteristics that influence the decision perform revision surgery among patients with proximal junctional failure (PJF). Summary of Background Data. Revision rates after PJF remain relatively high, yet criteria for performing surgical procedures are not uniform vary by surgeon. A better understanding factors impact is important in order improve...
OBJECT Regional cervical sagittal alignment (C2-7 vertical axis [SVA]) has been shown to correlate with health-related quality of life (HRQOL). The study objective was examine the relationship between and thoracolumbar parameters HRQOL among patients operative nonoperative adult deformity. METHODS This is a multicenter prospective data collection consecutive spinal Clinical measures disability included Oswestry Disability Index (ODI), Scoliosis Research Society-22 Patient Questionnaire...
In Brief Study Design. Retrospective review. Objective. To analyze the trends in complications and mortality after spinal fusions. Summary of Background Data. Utilization fusions has been increasing during past decade. It is essential to evaluate surgical outcomes better identify patients who benefit most from intervention. Integration empiric evidence large administrative databases into clinical decision making instrumental providing higher-quality, evidence-based, patient-centered care....
Object Incremental cost-effectiveness analysis is critical to the efficient allocation of health care resources; however, incremental ratio (ICER) surgical versus nonsurgical treatment for adult spinal deformity (ASD) has eluded literature, due in part inherent empirical difficulties when comparing and patients. Using observed preoperative health-related quality life (HRQOL) patients who later underwent surgery, this study builds a statistical model predict hypothetical quality-adjusted...
Objectives To quantify the cost savings of palliative care ( PC ) and identify differences in according to team structure, patient diagnosis, timing consult. Data Sources Hospital administrative records on all inpatient stays at five hospital campuses from January 2009 through June 2012. Study Design The analysis matched patients non‐ (separately by discharge status) using propensity score methods. Weighted generalized linear model regressions costs were estimated for groups. Collection...
Spinal osteotomies for adult spinal deformity correction may include resection of all 3 columns (pedicle subtraction osteotomy [PSO] and vertebral column [VCR]). The relationship between patient age health-related quality life (HRQOL) outcomes patients undergoing major via PSO or VCR has not been well characterized. goal this study was to characterize that relationship.This a retrospective review 374 who had undergone 3-column (299 PSOs 75 VCRs) were part prospectively collected, multicenter...
Recall of the informed consent process in patients undergoing adult spinal deformity surgery and their family members was investigated prospectively.To quantify percentage recall most common complications discussed during surgery, assess for differences between members, correlate with mental status.Given high rates it is critical to shared decision making that are adequately about risks able preoperative discussion possible mitigate medical legal risk.Patients underwent an augmented...
Abstract There is an increasing perception among policy makers that food stamp benefits contribute positively to adult obesity rates. We show these results are heavily dependent on one's assumptions regarding the accuracy of reported participation. When allowing for misreporting, we find no evidence Supplemental Nutrition Assistance Program participation significantly increases probability being obese or overweight adults. Our also highlight inherent bias and inconsistency common point...
The Centers for Medicare and Medicaid Services (CMS) has calculated disseminated an overall contract quality star rating system (from one to five stars) all Advantage (MA) contracts since 2009. In this paper, we study the effect of CMS-reported ratings on MA plan enrollment. We formulate a discrete choice demand model differentiated plans estimate with market-level enrollment data. identify separate effects each level using regression discontinuity research design that exploits plausibly...
We present a new command, tebounds, that implements variety of techniques to bound the average treatment effect binary on outcome in light endogenous and misreported assignment. To tighten worst case bounds, monotone selection, response, instrumental-variable assumptions Manski Pepper (2000, Econometrica 68: 997–1010), Kreider (2007, Journal American Statistical Association 102: 432–441), et al. (2012, 107: 958–975), Gundersen, Kreider, Econometrics 166: 79–91) may be imposed. Imbens–Manski...
The first methodologic step needed to compare pediatric health outcomes at children's hospitals (CHs) and non-children's (NCHs) is classify into CH NCH categories. However, there are currently no standardized or validated methods for classifying hospitals. purpose of this study was describe a novel reproducible hospital classification methodology.By using data from the 2015 American Hospital Association survey, 4464 were classified 4 categories (tiers A-D) on basis self-reported presence...
Postoperative venous thromboembolic events (VTEs), which include pulmonary emboli and deep thromboses, are potentially preventable causes of death. The aim this study was to investigate the patient procedure-related risk factors for occurrence VTEs in patients undergoing spinal fusion.We used ICD-9-CM (International Classification Diseases, 9th Revision, Clinical Modification) procedure codes identify Nationwide Inpatient Sample (NIS) database 2001 through 2010 who were treated with fusion....
Single-center, retrospective study of consecutive surgeries.This aimed to evaluate the reliability previously published anterior fusion grading systems and assess ability health-related quality-of-life (HRQOL) outcomes predict pseudarthrosis (PSAR).Despite existing radiographic indicators, PSAR may still go unidentified on biplanar radiographs, little data is available such in adult spinal deformity patients. As such, there a need for practical, noninvasive tool help identify PSAR.This...
<h3>Importance</h3> Although children's hospitals (CH) provide a substantial proportion of highly specialized pediatric care in the United States, value CH compared with non–children's (NCH) for routine surgical procedures is unknown. <h3>Objective</h3> To examine by assessing clinical outcomes and payment data. <h3>Design, Setting, Participants</h3> This retrospective cohort study examined patients undergoing 1 13 commonly performed between 2010 2015 90-day follow-up using administrative...
