Pair Scanning: Integrating the Student Sonographer Without Impacting Patient Care

Ultrasound departments in Canada frequently reduce patient bookings to support student training, which impacts not only patient care but also revenue generation. Therefore, physicians and employers are reluctant to host student sonographers, and educational programs struggle to find sufficient clinical placements for their students. Two research questions were investigated: (1) Can a pair scanning technique effectively integrate the student sonographer into the workplace without impacting patient volumes? (2) Does the pair scanning technique prepare the student sonographer for entry-level practice faster than traditional practice?

This research project was divided into 2 phases. The first phase used action research to develop the pair scanning protocol at a single site with a single preceptor and student. The second phase used a mixed methods approach to test the transferability of the pair scanning protocol across multiple sites, preceptors, and students.

In phase 1, the student sonographer performed a greater number of total examinations than the rest of her cohort (who were at different placement sites), and the higher performance of independent examinations by the student sonographer under the pair scanning technique was statistically significant [H₍₄₎  = 36.297; P < .01]. In phase 2, the pair scanning group and the control group performed equally, with no statistically significant differences.

The pair scanning protocol is effective at integrating the student sonographer into the work flow without impacting patient care. It prepares the student sonographer for entry-level practice equally with traditional practice and may be most effective with the weak to average student.
