Date of Publication: August 2019. | Journal: | EMA - Emergency Medicine Australasia | Abstract: | Objective: To determine accuracy and best cut-point of measured and percentage visual analog scale (VAS) change for detection of symptom improvement. Method(s): A pooled analysis of three previously published studies was conducted. All patients had baseline and 30 min VAS ratings linked to described symptom change. A receiver operating characteristic curve analysis was performed. Result(s): Area under the curve for detecting symptom improvement was 0.86 (95% CI 0.83-0.90) and 0.87 (95% CI 0.84-0.90) for measured and percentage VAS change. Best cut-points were -8 mm and -20%. Conclusion(s): Accuracy of VAS change for detection of symptom improvement is good to excellent. Use of this outcome measure in future ED antiemetic trials is supported.Copyright © 2019 Australasian College for Emergency Medicine | DOI: | http://monash.idm.oclc.org/login?url=http://dx.doi.org/10.1111/1742-6723.13291 | PubMed URL: | 30950219 [http://www.ncbi.nlm.nih.gov/pubmed/?term=30950219] | ISSN: | 1742-6731 | URI: | https://repository.monashhealth.org/monashhealthjspui/handle/1/36077 | Type: | Article | Subjects: | diagnostic test accuracy study *disease severity female *general condition improvement human major clinical study measurement accuracy *nausea outcome assessment predictive value priority journal receiver operating characteristic sensitivity and specificity *visual analog scale male adult area under the curve article controlled study male measurement accuracy *nausea outcome assessment predictive value priority journal receiver operating characteristic sensitivity and specificity *visual analog scale *general condition improvement female *disease severity diagnostic test accuracy study controlled study Article area under the curve adult human major clinical study |
