Accuracy of Point-of-Care Ultrasound in Follow Up Abdominal Aortic Aneurysm Imaging

Multiorgan Point-of-Care Ultrasound Assessment in Critically Ill Adults

Traditional point-of-care ultrasound (POCUS) training highlights discrete techniques, single-organ assessment, and focused protocols. More recent developments argue for a whole-body approach, where the experienced clinician-ultrasonographer crafts a personalized POCUS protocol depending on specific clinical circumstances. This article describes this problem-based approach, focusing on common acute care scenarios while highlighting practical considerations and performance characteristics.

Bedside Clinical Hand-held Ultrasound in an Internal Medicine Department: The "Bed Med-Us" Experience of Codogno and its Clinical Utility in the Management of Diagnosis and Therapy in 1007 Patients

Purpose Handheld ultrasound (HH-US) answers simple clinical questions in emergencies. We performed conventional US with HH-US at the patient's bedside (BED) during a medical visit (MED) (BED MED-US). The purpose of this prospective study is to estimate BED MED-US reliability, its clinical impact in helping the clinician to formulate correct diagnoses, and its ability to save time and money. Materials and Methods 1007 patients (519 M; age:76.42) were assessed (from March 2021 to November 2022) in one or more districts. Final diagnosis was determined with clinical and reference tests (chest RX/CT, abdominal CT, endoscopy, etc.). Sensitivity, specificity, LR+ and LR-, and corresponding AUROC were evaluated. HH-US diagnoses were classified as: confirmation (HH-US revealed the sonographic signs that confirmed the clinical diagnosis) (CO), exclusion (HH-US excluded the presence of the ultrasound signs of other pathologies, in the clinical differential diagnosis) (EX), etiological (HH-US reaches diagnosis in clinically doubtful cases) (ET), or clinically relevant incidental (HH-US diagnoses that change the patient's process completely) (INC). Results HH-US reliability: true-pos: 752; true-neg: 242; false-pos: 7; false-neg: 6 (sens: 99.1%, spec: 97.6%, LR+: 98.5; LR-: 00.15, AUROC: 0.997); clinical impact: CO-diagnosis: 21%; EX: 25%; ET: 47%; INC: 7%; saved time and money: approximately 35,572 minutes of work and 9324 euros. Conclusion BED MED-US is a reliable clinical imaging system, with an important clinical impact both in diagnosis (etiological in 47%, incidental in 7%) and in the management of personnel resources.

An Interdisciplinary Approach to the Introduction of Point-of-Care Ultrasound in an Urban Academic Primary Care Center

Introduction Limited guidance exists for primary and urgent care ultrasound applications. This study sought to identify the most useful applications for providers in these clinical settings, to create and implement a structured interdisciplinary point-of-care ultrasound (POCUS) curriculum, and to assess the effectiveness of the course.  Methods This prospective cohort study took place at an urban academic medical center. After a needs-based assessment of ultrasound applications in primary and urgent care, the Emergency Medicine ultrasound faculty and fellows were paired with a primary or urgent care provider (N = 6). The pairings met for scanning sessions in the emergency department to practice image acquisition, documentation, and incorporation of ultrasound into the workflow. Participants were given POCUS pre-work to review before each session. The final bedside session included a formal Objective Standard Clinical Examination (OSCE) to assess learner proficiency to be cleared for independent imaging. The program was assessed using pre- and post-training surveys.  Results The survey results demonstrated that renal, gallbladder, and soft tissue scans were the most interesting and useful to primary and urgent care providers after completion of the training course.  Conclusion The course was effective, and efficient, simple, high-yield POCUS applications should be included in future programs and organizational guidelines for primary and urgent care POCUS education.
