Can Technology Improve the Quality of Resuscitation ?
instructor sensitivity and instructor specificity .
Instructor sensitivity is when the instructor accurately “ passes ” a learner on an assessment that should have passed as judged by objective manikin data . As an example , think of compression depth . If 60 learners perform compressions in the correct depth range as judged by a manikin , and the instructor passes 55 of the 60 , instructor sensitivity would be 0.92 . Instructor sensitivity is the proportion of the learners that were accurately passed by the instructor that should have passed based on an objective measure .
Instructor specificity is the accuracy in “ failing ” learners that should have failed on an assessment when compared to an objective criterion such as manikin data . For example , if 100 assessments were judged by manikin data to fail and the instructor failed 25 of them , instructor specificity is low — it would be 0.25 .
Is it Possible to Accurately Assess Key CPR Performance Metrics ?
A 2016 Danish study helped bring the challenges of accurate CPR skills assessment into sharper focus . ( Hansen , 2019 ) The purpose of the study was to “ investigate certified BLS instructors ’ assessment skills in terms of identifying adequate and improper performances of chest compressions and rescue breathing .” ( p . 281 )
After completing a four-hour training course , all learners were
