Effects of using an abdominal simulator to develop palpatory competencies in 3rd year medical students

BACKGROUND

Medical school faculty are hard pressed to provide clerkship students with sufficient opportunity to develop and practice their capacity to perform a competent clinical examination, including the palpatory examination of the abdomen. We evaluated the impact of training with an abdominal simulator, AbSim, designed to monitor the depth, location, and thoroughness of their palpation and to provide concurrent and summative feedback regarding their performance.

METHODS

All third-year medical students were given the opportunity to develop their palpatory skills with the AbSim simulator during the family medicine rotation. The performance of those who studied with the simulator was measured by its sensors, before and after a training session that included visual feedback regarding the depth and coverage of the student's manual pressure. Additionally, all students reported their confidence in their evolving abdominal palpation skills at the beginning and end of the rotation.

RESULTS

119 (86.9%) of 137 students filled out the initial questionnaire, and 73 (61.3%) studied with the abdominal simulator. The training produced a highly significant improvement in their overall performance (4 measures, p's < 0.001). Pre-training performance (depth calibration and thoroughness of coverage) was not related to the number of months of previous clinical rotations nor to previous internal medicine or surgery rotations. There was little relation between students' confidence in their abdominal examination skills and objective measures of their palpatory performance; however, students who chose the training started with less confidence, and became more confident after training.

CONCLUSIONS

Guided abdominal simulator practice increased medical students' capacity to perform an abdominal examination with more appropriate depth and thoroughness of palpation. Interpretation of changes in confidence are uncertain, because confidence was unrelated to objectively measured performance. However, students with low initial confidence in their abdominal examination seemed to be more likely to choose to study with the abdominal simulator.

Skin cancer knowledge, attitudes, and practices among non-medical skin care professionals: A narrative review of cross-sectional and interventional studies

BACKGROUND

Skin cancers are the most common malignancies in the United States. Total body skin examination by a physician, especially a dermatologist, is the gold standard for detecting suspicious lesions that may require further evaluation. Non-medical professionals (NMPs) including massage therapists, estheticians, hairdressers, and cosmetologists have the unique opportunity to frequently examine their client's skin outside of a clinical setting. By evaluating their knowledge of and comfort with evaluation of suspicious lesions, multiple studies have gauged the utility of patient encounters with NMPs for skin cancer detection. Several studies have also focused on assessment of intervention strategies for assessing and improving NMPs ability to detect suspicious lesions and to refer for physician evaluation when necessary.

AIMS

To conduct a narrative review of skin cancer knowledge, attitudes, and practices among NMPs.

PATIENTS/METHODS

A systematic search of the databases yielded 16 studies for review. A total of 8 cross-sectional studies examined the knowledge and attitudes of NMPs toward skin evaluation, and 8 studies assessed interventional strategies for improving NMPs' ability to assess skin lesions for consideration of physician referral.

RESULTS

This review finds that NMPs are open to the idea of examining the exposed body surfaces relevant to their work with clients and are willing to refer for physician evaluation when needed. Multiple interventional strategies have demonstrated success with educating NMPs on the importance of skin surveillance and the characteristic physical examination findings associated with skin cancers.

CONCLUSION

Strengthening the readiness of NMPs to examine their client's skin offers an opportunity to reduce time to skin cancer diagnosis, improve patient outcomes, and lower healthcare-associated costs of skin cancer treatment.
