RESUMO
INTRODUCTION: Simulation enables medical students to practice clinical skills in a safe environment. Graduates in medicine must be able to correctly perform an examination on a pregnant woman using Leopold maneuvers. Learning curves-cumulative summation (LC-CUSUM) may help determine when the student has achieved a specific skill. Our objective was to perform the LC-CUSUM test regarding the ability of students to correctly carry out Leopold maneuvers; a pregnancy simulator was used, transferring the results to a clinical setting. METHODS: Five medical students were trained to carry out Leopold maneuvers using the simulator. Each student performed maneuvers for 50 cases of different fetus positions; a LC-CUSUM was plotted for each student. Afterward, the students performed the Leopold maneuvers on 5 pregnant women. RESULTS: Of the 5 students, 3 achieved a level of proficiency; the attempts needed for reaching this level were 13, 13, and 37, respectively. The other 2 students did not reach proficiency level. Of the students who became successfully proficient with the simulator, one of them attained a 100% success rate in pregnant patients, whereas the other two had success rates of 80%. The students who did not achieve a level of competency with the simulator had only a 60% success rate with patients. CONCLUSIONS: Because of the differences observed between students in the number of attempts needed for achieving proficiency in Leopold maneuvers, we believe that each student should build his/her own learning curve. Achieving competency in carrying out Leopold maneuvers using the simulator could be transferable to patients.
