OBJECTIVE: To test a novel set of pelvic trainers for realism and construct validity.
METHODS: Seven models of the female pelvis were studied. Participants performed speculum and bimanual examinations, documented their findings, and recorded opinions of the models in a structured questionnaire. Results were analyzed by participant grade (inexperienced and experienced).
RESULTS: Twenty-six inexperienced and 24 experienced gynecologists participated. Experienced doctors were more likely to correctly identify the uterus corresponding to 16 weeks of gestation (P<0.001), the large fibroid uterus (P=0.01), and uterine anteversion (P=0.04). Identification of the uterus containing a small fibroid, the uterus corresponding to 10 weeks of gestation, and an adnexal cyst was low overall (<35%) and not significantly different between the groups. Correct identification of cervical findings (ectropion and polyp) was high in both groups (65%-88%). Experienced doctors were more consistent-with 17 (71%) reporting the same correct finding on a repeated model, compared with 8 (31%) inexperienced doctors. Forty-nine (98%) doctors completed the structured questionnaire, 36 (73%) of whom felt the models were realistic.
CONCLUSION: The models were found to be realistic and have construct validity. Senior participants were consistent at correctly identifying most abnormalities. The models may be useful for pelvic examination training; further testing is required regarding their ability to aid learning of clinical and communication skills.
