Abstract
Background:
The learning curve in paediatric oesophagogastroduodenoscopy (OGD) is unknown. Using ≥95% D2 (second part of the duodenum) intubation rates as a marker of technical competency, we conducted learning curve analyses to identify when trainees achieve competency in paediatric OGD. Factors associated with competency were also evaluated.
Methods:
This nationwide study analysed data from paediatric OGD procedures prospectively entered into the UK endoscopy training e-portfolio between 2014 and 2018. Moving average and learning curve cumulative summation analyses were performed to determine procedural numbers required to achieve ≥95% D2 intubation rates. Factors associated with D2 intubation were assessed using a multivariable binary logistic regression approach.
Results:
A total of 8929 procedures performed by 61 trainees were identified. These 61 trainees had recorded a mean of 124.6 procedures (range 22–571, interquartile range 165). By moving average analysis, 95% D2 intubation was achieved after 79 procedures. By learning curve cumulative summation analysis, 81.6% of trainees were competent after 100 procedures. Multivariable factors associated with unassisted procedural completion included: lifetime procedure count (P < 0.001), higher trainee seniority (P < 0.001), patient age (P = 0.002), outpatient status (P < 0.001), and attendance at a national Basic Skills OGD course (P = 0.011).
Conclusions:
This study demonstrates that, on average, 79 procedures in paediatric OGD are required to attain the competency outcome of ≥95% D2 intubation rates. By 100 procedures, 81.6% of our sample had achieved ≥95% D2 intubation. The minimum procedural count of 100 set by the UK and international training programmes can be used alongside existing objective assessment measures to safeguard competency within a training cohort.
