Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? After four to nine real-world attempts a nurse's probability of success was over 70% on average. → Jørgensen Rasmus 2021
q2 i? In pediatric patients success rose from 67% after ten supervised attempts to 83% after ten additional unsupervised attempts. → Jørgensen Rasmus 2021 (2)

q2 · i? · review · r3
Review synthesis of learning-curve studies in nurses; the review reports "after four to nine real world attempts a nurse's probability of success was over 70% on average". Descriptive percentages only.
"Two studies found a relatively steep learning curve after initial training, and that after four to nine real world attempts a nurse's probability of success was over 70% on average [41, 42]."

q2 · i? · review · r3
The review reports pediatric learning-curve results: "a success rate of 67% after ten supervised attempts" rising to 83% after ten further unsupervised attempts. Ault et al. found the learning curve flattened after ten successful attempts.
"Likewise, results were seen in paediatric patients with a success rate of 67% after ten supervised attempts, and an increase after ten additional unsupervised attempts to 83% [27]."
Discussion¶
Related Claims¶
- Success rate after USG-PVC training does not differ significantly between nurses, physicians, and ED-technicians — related
- Mastery learning is feasible for USG-PVC training without extra time, and overtraining beyond mastery criteria does not improve performance — related
- The closer training content is to authentic clinical scenarios, the smoother its translation into practice — related
