Habilidades técnicas en suturas evaluadas con OSATS, comparando diferentes métodos de instrucción y acompañamiento

Introduction

Training students in non-clinical scenarios is necessary to prepare them for their encounters with patients.

Methods

An experimental prospective cohort research was conducted, with undergraduate students who performed a pretest, with previous theoretical instruction, then they were randomized into 3 groups, group 1 was accompanied by a surgeon, group 2 was accompanied by scrub nurse and group 3 practiced with videos. Subsequently, they performed a post-test, which was reviewed asyncronically by another surgeon, applying OSATS. In addition, students conducted surveys about their confidence.

Results

59 students participated, in the pretest the students behaved homogeneously. In the post-test, there was statistically significant improvement in all groups (p<0.001), with no differences between groups. Confidence in unsupervised suturing, instrument handling, and anxiety improved in all students at the end of the test.

Conclusion

It can be evidenced that involving technologies (videos) is equivalent to basic instruction by experts. OSATS is useful in formative assessment.

In conclusion, the method of instruction with video or accompaniment of experts are equivalent to the final result measured by the OSATS scale, as the perception of confidence of the students.
