Treatment with guideline-based therapy for CDI was associated with a trend toward a significantly lower LOS and cost. Barriers to physician adherence to guidelines still exist, despite education and guideline availability. Electronic health record-based order sets or clinical decision tools may improve recognition of and adherence to guidelines.

Introduction: Point-of-care ultrasound is recognized as a safe and valuable diagnostic tool for patient evaluation. Hospitalists are prime candidates for advancing the point-of-care ultrasound field given their crucial role in inpatient medicine. Despite this, there is a notable lack of evidence-based ultrasound training for hospitalists. Most research focuses on diagnostic accuracy rather than the training required to achieve it. This study aims to improve hospitalists' point-of-care ultrasound knowledge and skills through a hands-on skills practicum. Methods: Four skill practicums were conducted with pre-course, post-course, and six-month evaluations and knowledge assessments. Results: The mean pre-vs. post-course knowledge assessment scores significantly improved, 41.7% vs. 75.9% (SD 16.1% and 12.7%, respectively, p < 0.0001). The mean ultrasound skills confidence ratings on a 10-point Likert scale significantly increased post-course (2.60 AE 1.66 vs. 6.33 AE 1.63, p < 0.0001), but decreased at six months (6.33 AE 1.63 vs. 4.10 AE 2.22, p < 0.0001). The greatest limitations to usage precourse and at six months were knowledge/skills and lack of machine access. While knowledge/skills decreased from pre-course (82.0%) as compared to six-months (64.3%), lack of machine access increased from pre-course (15.8%) to six-months (28.6%) (p ¼ 0.28). Conclusion: Hospitalists agree that point-of-care ultrasound has utility in the diagnostic and therapeutic management of patients, though the lack of training is a significant limitation. Our study demonstrated that a brief skills practicum significantly improves hospitalists' confidence and knowledge regarding ultrasound image acquisition and interpretation in the short term. Long-term confidence and usage wanes, which appears to be due to the lack of machine access.

No relationship was observed between maintenance steroid dose prescribed and the duration of MV or ICU LOS. Evaluation of a safe and effective dose and duration of steroids in this population is warranted.
