"Shunt Pumping Test": role of practice on an experimental model.

Purpose: To ascertain the benefits of practicing shunt pumping test on a validated experimental model. Methods: A validated experimental model of shunt was used and 25 medical professionals were asked to assess the block in the model where artificial blocks were created. The assessment was repeated after the participants had practiced on the same model. The performance of participants before and after practice was compared and statistically evaluated. Results: The ability to predict the status of shunt showed an improvement in all scenarios after practice. The odds ratio for predicting a blocked shunt before and after practice was 7.25 (95% credible interval: 1.50–21.01). The odds ratio for predicting a functional shunt before and after practice was 8.81 (95% credible interval of 1.64 to 13.65). Conclusion: Practicing on the experimental model significantly improves the ability to predict the status of shunt. Training of primary caregivers on similar shunt models based on the shunts used in respective centers can improve an early detection of shunt block and reduce reliance on more invasive and expensive evaluation modalities.
