PURPOSE: Panoramic ultrasound is one of the recently introduced ultrasound evaluation techniques. We herein examined the relationship between the cross-sectional area of the rectus femoris muscle on panoramic ultrasound and its volume based on the gold standard computed tomography (CT) evaluation. METHODS: This was a single-center prospective observational study. A panoramic ultrasound assessment of the cross-sectional area of the rectus femoris muscle and a simple CT evaluation of its volume were performed on days 1 and 7 of hospitalization. Physical functions were assessed at discharge. RESULTS: Twenty patients were examined. The rate of change in the cross-sectional area of the rectus femoris muscle on panoramic ultrasound correlated with that in its volume on CT (correlation coefficient 0.59, p = 0.0061). In addition, a correlation was observed between the absolute value for the rectus femoris muscle cross-sectional area on panoramic ultrasound and physical functions at discharge. Rectus femoris muscle distances did not correlate with either. CONCLUSION: In the acute phase of critical illness, the cross-sectional area of the rectus femoris muscle on panoramic images correlated with its volume on CT and, thus, it is a valid method for assessing muscle mass.

Background It is important to learn interprofessional education (IPE) facilitation skills to promote interprofessional collaboration in healthcare. Nonetheless, to date, only a handful of IPE facilitation programs have been developed through research. Objective The objective of this study was to create an IPE facilitation program for healthcare professionals who wanted to promote interprofessional collaboration in their organizations based on the tenets of instructional design and evaluate its effectiveness. Methods This study's methodology was a mixed method based on relative subjectivism. We developed a two-day IPE facilitation program to learn IPE facilitation skills and promote interprofessional collaboration in the participants' own organizations. The program was developed based on the instructional design principles of the attention, relevance, confidence, and satisfaction (ARCS) model, measuring the participants' Interprofessional Facilitation Scale (IPFS) scores at three time points: before the first day, after the second day, and approximately one year after the course was completed. A one-way analysis of variance test was used to compare IPFS means at the three time points, and open-ended statements were qualitatively analyzed using thematic analysis. Results Twelve healthcare providers (four physicians, two pharmacists, one nurse, one rehabilitation worker, one medical social worker, one clinical psychologist, one medical secretary, and one other) participated in the completed IPE facilitation program. Their IPFS scores increased significantly from 17.4 ± 16.1 before the program to 38.1 ± 9.4 after the program and remained at 35.1 ± 11.7 for one year (p = 0.008). In addition, qualitative analysis suggested that the knowledge and skills learned in the program could be applied in the participants' workplaces, which helped them maintain their IPE facilitation skills. Conclusion We developed a two-day IPE facilitation program based on the ARCS instructional design model, and the participants' IPE facilitation skills scores increased and were maintained one year later.
