Point-of-care Ultrasound Diagnosis of Bilateral Patellar Tendon Rupture.

Clin Pract Cases Emerg Med 2020 Feb 24;4(1):29-31. Epub 2020 Jan 24.

George Washington University, Department of Emergency Medicine, Washington, District of Columbia.

Musculoskeletal complaints are one cornerstone of urgent issues for which orthopedic and emergency physicians provide care. Ultrasound can be a useful diagnostic tool to help identify musculoskeletal injuries. We describe a case of bilateral patellar tendon rupture that presented after minor trauma, and had the diagnosis confirmed at the bedside by point-of-care ultrasound. Physicians caring for patients with orthopedic injuries should be familiar with the use of ultrasound to diagnose tendon ruptures.

Direct Observation Assessment of Ultrasound Competency Using a Mobile Standardized Direct Observation Tool Application With Comparison to Asynchronous Quality Assurance Evaluation.

AEM Educ Train 2019 Apr 19;3(2):172-178. Epub 2019 Feb 19.

Department of Emergency Medicine The George Washington University Washington DC.

Objectives: Competency assessment is a key component of point-of-care ultrasound (POCUS) training. The purpose of this study was to design a smartphone-based standardized direct observation tool (SDOT) and to compare a faculty-observed competency assessment at the bedside with a blinded reference standard assessment in the quality assurance (QA) review of ultrasound images.

Methods: In this prospective, observational study, an SDOT was created using SurveyMonkey containing specific scoring and evaluation items based on the Council of Emergency Medicine Residency-Academy of Emergency Ultrasound: Consensus Document for the Emergency Ultrasound Milestone Project. Ultrasound faculty used the mobile phone-based data collection tool as an SDOT at the bedside when students, residents, and fellows were performing one of eight core POCUS examinations. Data recorded included demographic data, examination-specific data, and overall quality measures (on a scale of 1-5, with 3 and above being defined as adequate for clinical decision making), as well as interpretation and clinical knowledge. The POCUS examination itself was recorded and uploaded to QPath, a HIPAA-compliant ultrasound archive. Each examination was later reviewed by another faculty blinded to the result of the bedside evaluation. The agreement of examinations scored adequate (3 and above) in the two evaluation methods was the primary outcome.

Results: A total of 163 direct observation evaluations were collected from 23 EM residents (93 SDOTs [57%]), 14 students (51 SDOTs [31%]), and four fellows (19 SDOTs [12%]). The trainees were evaluated on completing cardiac (54 [33%]), focused assessment with sonography for trauma (34 [21%]), biliary (25 [15%]), aorta (18 [11%]), renal (12 [7%]), pelvis (eight [5%]), deep vein thrombosis (seven [4%]), and lung scan (5 [3%]). Overall, the number of observed agreements between bedside and QA assessments was 81 (87.1% of the observations) for evaluating the quality of images (scores 1 and 2 vs. scores 3, 4, and 5). The strength of agreement is considered to be "fair" (κ = 0.251 and 95% confidence interval [CI] = 0.02-0.48). Further agreement assessment demonstrated a fair agreement for images taken by residents and students and a "perfect" agreement in images taken by fellows. Overall, a "moderate" inter-rater agreement was found in 79.1% for the accuracy of interpretation of POCUS scan (e.g., true positive, false negative) during QA and bedside evaluation (κ = 0.48, 95% CI = 0.34-0.63). Faculty at the bedside and QA assessment reached a moderate agreement on interpretations noted by residents and students and a "good" agreement on fellows' scans.

Conclusion: Using a bedside SDOT through a mobile SurveyMonkey platform facilitates assessment of competency in emergency ultrasound learners and correlates well with traditional competency evaluation by asynchronous weekly image review QA.

Ultrasound-guided intravenous access in adults using SonoStik, a novel encapsulated sterile guidewire: A prospective cohort trial.

J Vasc Access 2018 Sep 12;19(5):441-445. Epub 2018 Mar 12.

1 Department of Emergency Medicine, The George Washington University Medical Center, Washington, DC, USA.

Purpose: We evaluated the performance of an encapsulated guidewire designed for single-handed use with ultrasound-guided vascular access (SonoStik) with Seldinger technique, as compared with conventional intravenous catheters placed under ultrasound guidance in healthy subjects.

Methods: This is a prospective cohort trial in healthy subjects in which each subject served as his/her own control by having a SonoStik ultrasound intravenous cannulation placed in one arm and a conventionally placed, standard ultrasound intravenous cannulation placed in the other arm. The basilic vein was used because it is a non-visible and non-palpable vein. Emergency department technicians with extensive experience in ultrasound-guided intravenous access performed the procedures. The first-attempt success rate of intravenous-guided intravenous by using the SonoStik was compared to the standard ultrasound intravenous cannulation in adult healthy subjects. The secondary outcomes including time of procedure, technicians' and subjects' satisfaction, and complications were compared in both arms of the study.

Results: A total of 24 volunteers with a mean age of 22.7 years were enrolled. Four emergency department technicians with extensive prior experience with ultrasound-guided intravenous access but with no prior experience using the SonoStik device performed the procedures. The first-attempt success was 83.3% with the use of SonoStik ultrasound intravenous cannulation compared to 95.8% with the standard ultrasound intravenous cannulation. There was a mean of 1.14 insertions per each successful placement in the SonoStik group compared to 1.04 insertions by using the standard catheters (mean differences = -0.1; 95% confidence interval = -0.6 to 0.4). There were no complications in either SonoStik or the standard ultrasound intravenous cannulation group. The mean time of insertion using SonoStik was slightly longer compared to standard ultrasound intravenous cannulation (143.3 vs 109.7 s).

Conclusion: This study demonstrated that emergency department technicians skilled in ultrasound-guided intravenous access could successfully place SonoStik 83.3% of the time in vessels that were unable to be palpated or visualized. Compared to standard ultrasound intravenous cannulation, the odds ratio of successful cannulation with SonoStik was 0.91 (95% confidence interval = 0.04-17.5). In all cases, the time required to successfully insert SonoStik was less than 4 min from tourniquet application to catheter advancement to hub, with a mean time of less than 2.5 min.

Impact of demographic and comorbid conditions on quality of life of hemodialysis patients: a cross-sectional study.

Saudi J Kidney Dis Transpl 2014 Mar;25(2):432-7

College of Medicine, King Abdulaziz University, Jeddah, Saudi Arabia.

To assess the quality of life (QOL) of Saudi Arabian patients undergoing hemo-dialysis (HD) and to determine the impact of gender, age, education and comorbidities on the QOL of these patients, we conducted a cross-sectional study and used the short form-36 (SF-36) questionnaire, a generic instrument for measuring QOL. This questionnaire is composed of eight scales that summarize the physical component scale (PCS) and mental component scale (MCS) of health status. We calculated the PCS and MCS scores for each patient. We studied 205 HD patients (123 men; ages 18-75 years) from the King Fahd General Hospital, Jeddah, Saudi Arabia. The mean SF-36 score was 59.4 ± 21.7 in men and 41.9 ± 20.9 in women (P <0.0001). Patients older than 60 years had the worst score (41.5 ± 21.2), followed by patients aged 40-59 years (53.6 ± 22.8); patients aged 18-39 years had the best SF-36 score (57.5 ± 22.5; P <0.0001). Education had a positive impact on QOL (P <0.0001), whereas comorbid conditions had a negative impact. Peripheral vascular disease was associated with the worst outcome (SF-36 score, 40.4 ± 23.0; P <0.0001), followed by dyslipidemia (42.9 ± 22.4; P = 0.001) and diabetes mellitus (45.0 ± 22.0; P = 0.012). Among the comorbid conditions, hypertension was associated with the best SF-36 score (50.6 ± 22.7; P = 0.034). We conclude that old age, female gender, poor education and comorbid conditions have a negative impact on the QOL of HD patients in Saudi Arabia. These findings indicate a general need for social support for female patients on HD and early diagnosis and management of comorbid conditions.
