Study Introduction
• Background– Pediatric skills training has traditionally employed the
apprenticeship model of “see one, do one, teach one” at the patients bedside
– Simulation-based interventions are well received by trainees and faculty
– No systematic evaluation for their effect on pediatric patient outcomes

Study Introduction
• Deliberate practice is a key feature of simulation-based interventions for learning complex procedures
• A study by Conroy reported that interns who participated in deliberate practice on adult LP task trainers with focused feedback developed high levels of skill and retained these skills on the simulator at 3 to 6 months

Study Introduction
• Hypothesis
Mastery training with coached deliberate practice on an infant LP simulator combined with an audiovisual training (AV) will improve clinical success rates with the procedure
![Page 7: KidSIM Journal Club Presenter: Amani Azizalrahman June 19 th, 2014.](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f115503460f94c2490a/html5/thumbnails/7.jpg)
Study Design
• Design/ Methods – Residents were randomized within class year using a
random number generator to participate in either intervention or control groups.
– In an urban tertiary care Department of Pediatrics.
– The local institutional review board approved this study.
– Informed consent at the start of the year was obtained.

PICO Question
P: pediatric residents
I : watch audiovisual presentation on the LP procedure, hands-on simulation-based coached deliberate practice training session
C: watch audiovisual presentation on the LP procedure
O: improvement in pediatrics resident skills and confidence during LP for infant

Study Design
• Baseline Assessment
- questionnaires were completed to assess:
(1) Prior training
(2) Experience with the infant LP procedure
(3) Knowledge (using a 6-item quiz)
(4) Confidence with the procedure (using a 4-point Likert scale)
![Page 10: KidSIM Journal Club Presenter: Amani Azizalrahman June 19 th, 2014.](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f115503460f94c2490a/html5/thumbnails/10.jpg)
Study Design
• Baseline Assessment– Individuals from both groups were then videotaped
performing an LP on a Laerdal Baby Stap neonatal task trainer
– (OSCE) was scored by the instructors on the day of training and later using video review by an author blinded to group assignment, using a 15-item checklist of critical steps developed for this study

- Online data entry tool
- The participants answer questions measuring confidence, attitudes about their LP training experience after they had performed a clinical patient LP

– This study demonstrate the translation of a simulation skills training into improvements in providers’ clinical performance in pediatric

- Action-oriented coaching
- Mastery training on the simulator
![Page 27: KidSIM Journal Club Presenter: Amani Azizalrahman June 19 th, 2014.](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f115503460f94c2490a/html5/thumbnails/27.jpg)
Discussion
Limitations:- Clinical performance was measured by self-report
- The lack of true blinding of subjects to the interventions
- Underreporting at the 6-months follow-up
![Page 28: KidSIM Journal Club Presenter: Amani Azizalrahman June 19 th, 2014.](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f115503460f94c2490a/html5/thumbnails/28.jpg)
Discussion
Limitations:
- The OSCE checklist was not validated
- Teaching intervention was in a single training session
- Sample size did not provide adequate power to analyze all subgroups and confounders
![Page 29: KidSIM Journal Club Presenter: Amani Azizalrahman June 19 th, 2014.](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f115503460f94c2490a/html5/thumbnails/29.jpg)
Discussion
• Recommendation:
Future studies with large sample size
![Page 30: KidSIM Journal Club Presenter: Amani Azizalrahman June 19 th, 2014.](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f115503460f94c2490a/html5/thumbnails/30.jpg)
Conclusions
Simulation-based deliberate practice on an infant LP simulator after an audiovisual didactic improves the odds of obtaining CSF with the next clinical infant LP performed when compared with AV alone, independent of other factors
![Page 31: KidSIM Journal Club Presenter: Amani Azizalrahman June 19 th, 2014.](https://reader036.fdocuments.in/reader036/viewer/2022070400/56649f115503460f94c2490a/html5/thumbnails/31.jpg)
