Abstract

Background Limited information exists regarding the burden of emergency department (ED) visits due to scabies in the United States. The goal of this study was to provide population-level estimates regarding scabies visits to American EDs. Methods This study was a retrospective analysis of the nationally representative National Emergency Department Sample from 2013 to 2015. Outcomes included adjusted odds for scabies ED visits, adjusted odds for inpatient admission due to scabies in the ED scabies population, predictors for cost of care, and seasonal/regional variation in cost and prevalence of scabies ED visits. Results Our patient population included 416 017 218 ED visits from 2013 to 2015, of which 356 267 were due to scabies (prevalence = 85.7 per 100 000 ED visits). The average annual expenditure for scabies ED visits was $67 125 780.36. The average cost of care for a scabies ED visit was $750.91 (±17.41). Patients visiting the ED for scabies were most likely to be male children from lower income quartiles and were most likely to present to the ED on weekdays in the fall, controlling for all other factors. Scabies ED patients that were male, older, insured by Medicare, from the highest income quartile, and from the Midwest/West were most likely to be admitted as inpatients. Older, higher income, Medicare patients in large Northeastern metropolitan cities had the greatest cost of care. Conclusion This study provides comprehensive nationally representative estimates of the burden of scabies ED visits on the American healthcare system. These findings are important for developing targeted interventions to decrease the incidence and burden of scabies in American EDs. [ABSTRACT FROM AUTHOR]

Abstract

OBJECTIVEComplete radiographic and clinical evaluations are essential in the surgical treatment of cervical spondylotic myelopathy (CSM). Prior studies have correlated cervical sagittal imbalance and kyphosis with disability and worse health-related quality of life. However, little is known about C2-3 disc angle and its correlation with postoperative outcomes. The present study is the first to consider C2-3 disc angle as an additional radiographic predictor of postoperative adverse events.METHODSA retrospective chart review was performed to identify patients with CSM who underwent surgeries from 2010 to 2014. Data collected included demographics, baseline presenting factors, and postoperative outcomes. Cervical sagittal alignment variables were measured using the preoperative and postoperative radiographs. Univariable logistic regression analyses were used to explore the association between dependent and independent variables, and a multivariable logistic regression model was created using stepwise variable selection.RESULTSThe authors identified 171 patients who had complete preoperative and postoperative radiographic and outcomes data. The overall rate of postoperative adverse events was 33% (57/171), and postoperative C2-3 disc angle, C2-7 sagittal vertical axis, and C2-7 Cobb angle were found to be significantly associated with adverse events. Inclusion of postoperative C2-3 disc angle in the analysis led to the best prediction of adverse events. The mean postoperative C2-3 disc angle for patients with any postoperative adverse event was 32.3° ± 17.2°, and the mean for those without any adverse event was 22.4° ± 11.1° (p < 0.0001).CONCLUSIONSIn the present retrospective analysis of postoperative adverse events in patients with CSM, the authors found a significant association between C2-3 disc angle and postoperative adverse events. They propose that C2-3 disc angle be used as an additional parameter of cervical spinal sagittal alignment and predictor for operative outcomes.
