Evaluating the impact of structured POCUS training during internal medicine clerkship and residency training

Background: Point of Care Ultrasound (POCUS) is a vital tool in rheumatology for detecting pathologies like osteophytes and joint effusion. Its integration into rheumatology electives during internal medicine clerkship and residency is limited, despite its emphasis in pre-clinical years. Methods: In this QIRB-approved, single-center, prospective study (2022–2023), third- and fourth-year medical students and internal medicine residents in a two-week rheumatology elective voluntarily completed online surveys. These surveys assessed their confidence using POCUS in rheumatology, using a 5-point Likert scale. Results: A survey of 25 residents and 10 medical students found that 84% of residents and 90% of students rated POCUS training as valuable or very valuable. Both groups felt more confident identifying knee joint effusion (average scores: 3.5 for students, 2.6 for residents) compared to other ultrasound techniques and pathologies. Confidence was lower in hip ultrasounds (2.20 for students, 1.68 for residents) and chondrocalcinosis identification (2.20 for students, 1.76 for residents). Among participants, 28% of residents and 70% of students had prior informal POCUS training. Previous training significantly increased comfort levels, with average scores of 2.86 for students and 2.30 for residents, compared to 2.69 and 1.91 for those without prior training (P-values: <0.001). Conclusion: Prior experience significantly enhances confidence and comfort, reinforcing the need for early, comprehensive, and targeted POCUS training in medical curricula to address proficiency gaps.
