Brief summary
Point of care ultrasound (POCUS) is used ever more increasingly across the emergency medicine departments in India. Guided procedures like nerve blocks, vascular access, abscess drainage and foreign body exploration are done more conveniently and efficiently utilising visualisation under ultra sonography. Several training models are available commercially that aids in training the novice and expert in the field alike. The commercially available models are expensive and inaccessible for most, while the utility of POCUS in Emergency Department (ED) is on the rise. This has lead people to experiment with various models for training which ranges from basic gelatin moulds to ballistic gel. There are only a few studies that compare these with the commercially available products for educational purposes. The home made models are cheaper and more easily procurable for training making it a relatively favourable choice in financially constrained situations. The investigators have been using a gelatine based training model to train their emergency medicine residents for many years. In this study they intend to assess whether their indigenously developed ultrasound phantom model is comparable to commercially available models for vascular access training.They also sought to assess the better preliminary teaching model for ultrasound guided vascular access: in-plane or out-of-plane approach?

TRIPLE (Subject, Investigator, Outcomes Assessor)
Masking description
The examiners, examinees and statistician would be blinded to the nature of the model. The model would be matched in colour shape and size with the commercially available model. The models would be covered by a plastic surgical drape, with a label on top that said model A or model B. The models identity would be known only to the team leader. One the coin toss is complete and model allocated, the allocation would be marked unto a sealed envelope which would be opened only after data entry and analysis. Any untoward event needing unmasking of the models like damage to the model, warranting replacement was also carried out by the team leader.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Comparative scoring of the two ultrasound phantom models | 6 hours | Comparison of the two ultrasound model assessed on a five point Likert scale (1- worst score, 5- best score) in terms of resemblance, tactile feed back, artefacts and ease of use done at the end of the study. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Confidence in performing and teaching ultrasound guided vascular access using in plane approach | 6 hours | Post workshop confidence level change in performing and teaching needle tracking and vascular access, with in plane approach, assessed on a five point Likert scale (1- least confident score, 5- most confident) |
| Confidence in performing and teaching ultrasound guided vascular access using out of plane approach | 6 hours | Post workshop confidence level change in performing and teaching needle tracking and vascular access, with out of plane approach, assessed on a five point Likert scale (1- least confident score, 5- most confident) |
Other
| Measure | Time frame | Description |
