Missing Inferior Vena Cava on POCUS: A Case of Left-Sided IVC with Azygos Continuation.

The merits of utilizing point of care ultrasound (POCUS) in acutely ill patients is leading to a widespread embrace. Assessment of IVC via POCUS as part of a comprehensive multi-organ approach can help guide volume tolerance. Anatomical/developmental variations of IVC can vary widely in prevalence. As the use of POCUS expands as a diagnostic modality, it is prudent for frontline POCUS users to be cognizant of the IVC anomalies. We present a case of left sided IVC with azygous continuation discovered with POCUS that was performed to assess the volume status of the patient. This case illustrates that the awareness of different anomalies of the IVC is necessary for POCUS users to prevent misinterpretation of aberrant vessels and avoid diagnostic pitfalls.

Comparison of four handheld point-of-care ultrasound devices by expert users.

BACKGROUND: Point-of-care ultrasound (POCUS) is rapidly becoming ubiquitous across healthcare specialties. This is due to several factors including its portability, immediacy of results to guide clinical decision-making, and lack of radiation exposure to patients. The recent growth of handheld ultrasound devices has improved access to ultrasound for many clinicians. Few studies have directly compared different handheld ultrasound devices among themselves or to cart-based ultrasound machines. We conducted a prospective observational study comparing four common handheld ultrasound devices for ease of use, image quality, and overall satisfaction. Twenty-four POCUS experts utilized four handheld devices (Butterfly iQ+™ by Butterfly Network Inc., Kosmos™ by EchoNous, Vscan Air™ by General Electric, and Lumify™ by Philips Healthcare) to obtain three ultrasound views on the same standardized patients using high- and low-frequency probes. RESULTS: Data were collected from 24 POCUS experts using all 4 handheld devices. No single ultrasound device was superior in all categories. For overall ease of use, the Vscan Air™ was rated highest, followed by the Lumify™. For overall image quality, Lumify™ was rated highest, followed by Kosmos™. The Lumify™ device was rated highest for overall satisfaction, while the Vscan Air™ was rated as the most likely to be purchased personally and carried in one's coat pocket. The top 5 characteristics of handheld ultrasound devices rated as being "very important" were image quality, ease of use, portability, total costs, and availability of different probes. CONCLUSIONS: In a comparison of four common handheld ultrasound devices in the United States, no single handheld ultrasound device was perceived to have all desired characteristics. POCUS experts rated the Lumify™ highest for image quality and Vscan Air™ highest for ease of use. Overall satisfaction was highest with the Lumify™ device, while the most likely to be purchased as a pocket device was the Vscan Air™. Image quality was felt to be the most important characteristic in evaluating handheld ultrasound devices.

Comparison of in-person versus tele-ultrasound point-of-care ultrasound training during the COVID-19 pandemic.

BACKGROUND: Lack of training is currently the most common barrier to implementation of point-of-care ultrasound (POCUS) use in clinical practice, and in-person POCUS continuing medical education (CME) courses have been paramount in improving this training gap. Due to travel restrictions and physical distancing requirements during the COVID-19 pandemic, most in-person POCUS training courses were cancelled. Though tele-ultrasound technology has existed for several years, use of tele-ultrasound technology to deliver hands-on training during a POCUS CME course has not been previously described. METHODS: We conducted a retrospective observational study comparing educational outcomes, course evaluations, and learner and faculty feedback from in-person versus tele-ultrasound POCUS courses. The same POCUS educational curriculum was delivered to learners by the two course formats. Data from the most recent pre-pandemic in-person course were compared to tele-ultrasound courses during the COVID-19 pandemic. RESULTS: Pre- and post-course knowledge test scores of learners from the in-person (n = 88) and tele-ultrasound course (n = 52) were compared. Though mean pre-course knowledge test scores were higher among learners of the tele-ultrasound versus in-person course (78% vs. 71%; p = 0.001), there was no significant difference in the post-course test scores between learners of the two course formats (89% vs. 87%; p = 0.069). Both learners and faculty rated the tele-ultrasound course highly (4.6-5.0 on a 5-point scale) for effectiveness of virtual lectures, tele-ultrasound hands-on scanning sessions, and course administration. Faculty generally expressed less satisfaction with their ability to engage with learners, troubleshoot image acquisition, and provide feedback during the tele-ultrasound course but felt learners completed the tele-ultrasound course with a better basic POCUS skillset. CONCLUSIONS: Compared to a traditional in-person course, tele-ultrasound POCUS CME courses appeared to be as effective for improving POCUS knowledge post-course and fulfilling learning objectives. Our findings can serve as a roadmap for educators seeking guidance on development of a tele-ultrasound POCUS training course whose demand will likely persist beyond the COVID-19 pandemic.

Hospitalist Perceptions of Barriers to Lung Ultrasound Adoption in Diverse Hospital Environments.

Despite the many advantages of lung ultrasound (LUS) in the diagnosis and management of patients with dyspnea, its adoption among hospitalists has been slow. We performed semi-structured interviews of hospitals from four diverse health systems in the United States to understand determinants of adoption within a range of clinical settings. We used the diffusion of innovation theory to guide a framework analysis of the data. Of the 27 hospitalists invited, we performed 22 interviews from four hospitals of diverse types. Median years post-residency of interviewees was 10.5 [IQR:5-15]. Four main themes emerged: (1) There are important clinical advantages to LUS despite operator dependence, (2) LUS enhances patient and clinician experience, (3) Investment of clinician time to learn and perform LUS is a barrier to adoption but yields improved efficiency for the health system and (4) Mandated training and use may be necessary to achieve broad adoption as monetary incentives are less effective. Despite the perceived benefits of LUS for patients, clinicians and health systems, a significant barrier to broad LUS adoption is the experience of time scarcity by hospitalists. Future implementation strategies should focus on changes to the clinical environment that address clinician barriers to learning and adoption of new skills.

Webside manner: maskless communication.

Telemedicine has seen a rapid expansion lately, with virtual visits ushering in telediagnosis. Given the shift in the interpersonal and technical aspects of communications in a virtual visit, it is prudent to understand its effect on the patient-provider relationships. A range of interpersonal and communication skills can be utilized during telemedicine consultations in establishing relationships, and reaching a diagnosis. We propose a construct of "webside manner," a structured approach to ensure the core elements of bedside etiquette are translated into the virtual encounter. This approach entails the totality of any interpersonal exchange on a virtual platform, to ensure a clinician's presence, empathy and compassion is translated through this medium.

SPEAKers at the National Society of Hospital Medicine Meeting: A Follow-UP Study of Gender Equity for Conference Speakers from 2015 to 2019. The SPEAK UP Study.

Women continue to be underrepresented as speakers at national conferences, and research has shown similar trends in hospital medicine. The Society of Hospital Medicine (SHM) Annual Meeting has historically had an open call peer review process for workshop speakers and, in 2019, expanded the process for didactic speakers. We aimed to assess the overall conference trends for women speakers and whether the systematic processes in recruitment procedures (ie, open call) resulted in improved representation of women speakers. We also sought to understand how the proportion of women speakers might affect overall scores of the conference. From 2015 to 2019, the overall representation of women speakers increased, as did evaluation scores during the same time period. When selection processes included the open call peer review process, there were higher proportions of women speakers. An open call process with peer review for speakers may be a systematic process that national meetings could replicate to reduce gender inequities.

Demonstration of a Longitudinal Medical Education Model (LMEM) Model to Teach Point-of-Care Ultrasound in Resource-Limited Settings.

Background: Short-term medical missions prevail as the most common form of international medical volunteerism, but they are ill-suited for medical education and training local providers in resource-limited settings. Objective: The purpose of this study is to evaluate the effectiveness of a longitudinal educational program in training clinicians how to perform point-of-care ultrasound (POCUS) in resource-limited clinics. Design: A retrospective study of a four-month POCUS training program was conducted with clinicians from a rural hospital in Haiti. The model included one-on-one, in-person POCUS teaching sessions by volunteer instructors from the United States and Europe. The Haitian trainees were assessed at the start of the program and at its conclusion by a direct objective structured clinical examination (OSCE), administered by the visiting instructors, with similar pre- and post- program ultrasound competency assessments. Results: Post-intervention, a significant improvement in POCUS competency was observed across six different fundamental areas of ultrasound (p < 0.0001). According to our objective structured clinical examination (OSCE), the mean assessment score increased from 0.47 to 1.68 out of a maximum score of 2 points, and each trainee showed significant overall improvement in POCUS competency independent of the initial competency pre-training (p < 0.005). There was a statistically significant improvement in POCUS application for five of the six medically relevant assessment categories tested. Conclusion: Our results provide a proof-of-concept for the longitudinal education-centered healthcare delivery framework in a resource-limited setting. Our longitudinal model provides local healthcare providers the skills to detect and diagnose significant pathologies, thereby reducing avoidable morbidity and mortality at little or no addition cost or risk to the patient. Furthermore, training local physicians obviates the need for frequent volunteering trips, saving costs in healthcare training and delivery.

Structured case reviews for organizational learning about diagnostic vulnerabilities: initial experiences from two medical centers.

Background An organization's ability to identify and learn from opportunities for improvement (OFI) is key to increasing diagnostic safety. Many lack effective processes required to capitalize on these learning opportunities. We describe two parallel attempts at creating such a process and identifying generalizable lessons and learn from them. Methods Triggered case review programs were created independently at two organizations, Site 1 (Regions Hospital, HealthPartners, Saint Paul, MN, USA) and site 2 (University of California, San Diego). Both used a five-step process to create the review system and provide feedback: (1) identify trigger criteria; (2) establish a review panel; (3) develop a system to conduct reviews; (4) perform reviews; and (5) provide feedback. Results Site 1 identified 112 OFI in 184 case reviews (61%), with 66 (59%) provider OFI and 46 (41%) system OFI. Site 2 focused mainly on systems OFI identifying 105 OFI in 346 cases (30%). Opportunities at both sites were variable; common themes included test result management and communication across teams in peri-procedural care and with consultants. Of provider-initiated reviews, 67% of cases had an OFI at site 1 and 87% at site 2. Conclusions Lessons learned include the following: (1) peer review of cases provides opportunities to learn and calibrate diagnostic and management decisions at an organizational level; (2) sharing cases in review groups supports a culture of open discussion of OFIs; (3) reviews focused on diagnostic safety identify opportunities that may complement other organization-wide review opportunities.

Recommendations on the Use of Ultrasound Guidance for Central and Peripheral Vascular Access in Adults: A Position Statement of the Society of Hospital Medicine.

PREPROCEDURE: 1)We recommend that providers should be familiar with the operation of their specific ultrasound machine prior to initiation of a vascular access procedure. 2)We recommend that providers should use a high-frequency linear transducer with a sterile sheath and sterile gel to perform vascular access procedures. 3)We recommend that providers should use two-dimensional ultrasound to evaluate for anatomical variations and absence of vascular thrombosis during preprocedural site selection. 4)We recommend that providers should evaluate the target blood vessel size and depth during preprocedural ultrasound evaluation. TECHNIQUES: General Techniques 5) We recommend that providers should avoid using static ultrasound alone to mark the needle insertion site for vascular access procedures. 6)We recommend that providers should use real-time (dynamic), two-dimensional ultrasound guidance with a high-frequency linear transducer for central venous catheter (CVC) insertion, regardless of the provider's level of experience. 7)We suggest using either a transverse (short-axis) or longitudinal (long-axis) approach when performing real-time ultrasound-guided vascular access procedures. 8)We recommend that providers should visualize the needle tip and guidewire in the target vein prior to vessel dilatation. 9)To increase the success rate of ultrasound-guided vascular access procedures, we recommend that providers should utilize echogenic needles, plastic needle guides, and/or ultrasound beam steering when available. Central Venous Access Techniques 10) We recommend that providers should use a standardized procedure checklist that includes the use of real-time ultrasound guidance to reduce the risk of central line-associated bloodstream infection (CLABSI) from CVC insertion. 11)We recommend that providers should use real-time ultrasound guidance, combined with aseptic technique and maximal sterile barrier precautions, to reduce the incidence of infectious complications from CVC insertion. 12)We recommend that providers should use real-time ultrasound guidance for internal jugular vein catheterization, which reduces the risk of mechanical and infectious complications, the number of needle passes, and time to cannulation and increases overall procedure success rates. 13)We recommend that providers who routinely insert subclavian vein CVCs should use real-time ultrasound guidance, which has been shown to reduce the risk of mechanical complications and number of needle passes and increase overall procedure success rates compared with landmark-based techniques. 14)We recommend that providers should use real-time ultrasound guidance for femoral venous access, which has been shown to reduce the risk of arterial punctures and total procedure time and increase overall procedure success rates. Peripheral Venous Access Techniques 15) We recommend that providers should use real-time ultrasound guidance for the insertion of peripherally inserted central catheters (PICCs), which is associated with higher procedure success rates and may be more cost effective compared with landmark-based techniques. 16)We recommend that providers should use real-time ultrasound guidance for the placement of peripheral intravenous lines (PIV) in patients with difficult peripheral venous access to reduce the total procedure time, needle insertion attempts, and needle redirections. Ultrasound-guided PIV insertion is also an effective alternative to CVC insertion in patients with difficult venous access. 17)We suggest using real-time ultrasound guidance to reduce the risk of vascular, infectious, and neurological complications during PIV insertion, particularly in patients with difficult venous access. Arterial Access Techniques 18)We recommend that providers should use real-time ultrasound guidance for arterial access, which has been shown to increase first-pass success rates, reduce the time to cannulation, and reduce the risk of hematoma development compared with landmark-based techniques. 19)We recommend that providers should use real-time ultrasound guidance for femoral arterial access, which has been shown to increase first-pass success rates and reduce the risk of vascular complications. 20)We recommend that providers should use real-time ultrasound guidance for radial arterial access, which has been shown to increase first-pass success rates, reduce the time to successful cannulation, and reduce the risk of complications compared with landmark-based techniques. POSTPROCEDURE: 21) We recommend that post-procedure pneumothorax should be ruled out by the detection of bilateral lung sliding using a high-frequency linear transducer before and after insertion of internal jugular and subclavian vein CVCs. 22)We recommend that providers should use ultrasound with rapid infusion of agitated saline to visualize a right atrial swirl sign (RASS) for detecting catheter tip misplacement during CVC insertion. The use of RASS to detect the catheter tip may be considered an advanced skill that requires specific training and expertise. TRAINING: 23) To reduce the risk of mechanical and infectious complications, we recommend that novice providers should complete a systematic training program that includes a combination of simulation-based practice, supervised insertion on patients, and evaluation by an expert operator before attempting ultrasound-guided CVC insertion independently on patients. 24)We recommend that cognitive training in ultrasound-guided CVC insertion should include basic anatomy, ultrasound physics, ultrasound machine knobology, fundamentals of image acquisition and interpretation, detection and management of procedural complications, infection prevention strategies, and pathways to attain competency. 25)We recommend that trainees should demonstrate minimal competence before placing ultrasound-guided CVCs independently. A minimum number of CVC insertions may inform this determination, but a proctored assessment of competence is most important. 26)We recommend that didactic and hands-on training for trainees should coincide with anticipated times of increased performance of vascular access procedures. Refresher training sessions should be offered periodically. 27)We recommend that competency assessments should include formal evaluation of knowledge and technical skills using standardized assessment tools. 28)We recommend that competency assessments should evaluate for proficiency in the following knowledge and skills of CVC insertion: (a) Knowledge of the target vein anatomy, proper vessel identification, and recognition of anatomical variants; (b) Demonstration of CVC insertion with no technical errors based on a procedural checklist; (c) Recognition and management of acute complications, including emergency management of life-threatening complications; (d) Real-time needle tip tracking with ultrasound and cannulation on the first attempt in at least five consecutive simulation. 29)We recommend a periodic proficiency assessment of all operators should be conducted to ensure maintenance of competency.

Improving Resident Feedback on Diagnostic Reasoning after Handovers: The LOOP Project.

Appropriate calibration of clinical reasoning is critical to becoming a competent physician. Lack of follow-up after transitions of care can present a barrier to calibration. This study aimed to implement structured feedback about clinical reasoning for residents performing overnight admissions, measure the frequency of diagnostic changes, and determine how feedback impacts learners' self-efficacy. Trainees shared feedback via a structured form within their electronic health record's secure messaging system. Forms were analyzed for diagnostic changes. Surveys evaluated comfort with sharing feedback, self-efficacy in identifying and mitigating cognitive biases' negative effects, and perceived educational value of night admissions-all of which improved after implementation. Analysis of 544 forms revealed a 43.7% diagnostic change rate spanning the transition from night-shift to day-shift providers; of the changes made, 29% (12.7% of cases overall) were major changes. This study suggests that structured feedback on clinical reasoning for overnight admissions is a promising approach to improve residents' diagnostic calibration, particularly given how often diagnostic changes occur.

Hospitalist-Operated Compression Ultrasonography: a Point-of-Care Ultrasound Study (HOCUS-POCUS).

BACKGROUND: Venous thromboembolism includes deep vein thrombosis (DVT) and pulmonary embolism. Compression ultrasonography is the most common way to evaluate DVT and is typically performed by sonographers and interpreted by radiologists. Yet there is evidence that ultrasound examinations can be safely and accurately performed by clinicians at the bedside. OBJECTIVE: To measure the operating characteristics of hospital medicine providers performing point-of-care ultrasound (POCUS) for evaluation of DVT. DESIGN: This is a prospective cohort study enrolling a convenience sample of patients. Hospital medicine providers performed POCUS for DVT and the results were compared with the corresponding formal vascular study (FVS) interpreted by radiologists. PARTICIPANTS: Hospitalized non-ICU patients at four tertiary care hospitals for whom a DVT ultrasound was ordered. MAIN MEASURES: The primary outcomes were the sensitivity, specificity, and predictive values of the POCUS compression ultrasound compared with a FVS. The secondary outcome was the elapsed time between order and the POCUS study compared with the time the FVS was ordered to when the formal radiology report was finalized. KEY RESULTS: One hundred twenty-five limbs from 73 patients were scanned. The prevalence of DVT was 6.4% (8/125). The sensitivity of POCUS for DVT was 100% (95% CI 74-100%) and specificity was 95.8% (95% CI 91-98%) with a positive predictive value of 61.5% (95% CI 35-84%) and a negative predictive value of 100% (95% CI 98-100%). The median time from order to POCUS completion was 5.8 h versus 11.5 h median time from order until the radiology report was finalized (p = 0.001). CONCLUSION: Hospital medicine providers can perform compression-only POCUS for DVT on inpatients with accuracy similar to other specialties and settings, with results available sooner than radiology. The observed prevalence of DVT was lower than expected. POCUS may be reliable in excluding DVT but further study is required to determine how to incorporate a positive POCUS DVT result into clinical practice.

Point-of-Care Ultrasound for Hospitalists: A Position Statement of the Society of Hospital Medicine.

Many hospitalists incorporate point-of-care ultrasound (POCUS) into their daily practice to answer specific diagnostic questions or to guide performance of invasive bedside procedures. However, standards for hospitalists in POCUS training and assessment are not yet established. Most internal medicine residency training programs, the major pipeline for incoming hospitalists, have only recently begun to incorporate POCUS in their curricula. The purpose of this document is to inform a broad audience on what POCUS is and how hospitalists are using it. This document is intended to provide guidance for the hospitalists who use POCUS and administrators who oversee its use. We discuss POCUS 1) applications, 2) training, 3) assessments, and 4) program management. Practicing hospitalists must continue to collaborate with their local credentialing bodies to outline requirements for POCUS use. Hospitalists should be integrally involved in decision-making processes surrounding POCUS program management.

Recommendations on the Use of Ultrasound Guidance for Adult Abdominal Paracentesis: A Position Statement of the Society of Hospital Medicine.

1. We recommend that ultrasound guidance should be used for paracentesis to reduce the risk of serious complications, the most common being bleeding. 2. We recommend that ultrasound guidance should be used to avoid attempting paracentesis in patients with an insufficient volume of intraperitoneal free fluid to drain. 3. We recommend that ultrasound guidance should be used with paracentesis to improve the success rates of the overall procedure. 4. We recommend that ultrasound should be used to assess the volume and location of intraperitoneal free fluid to guide clinical decision making of where paracentesis can be safely performed. 5. We recommend that ultrasound should be used to identify a needle insertion site based on size of the fluid collection, thickness of the abdominal wall, and proximity to abdominal organs. 6. We recommend that the needle insertion site should be evaluated using color flow Doppler ultrasound to identify and avoid abdominal wall blood vessels along the anticipated needle trajectory. 7. We recommend that a needle insertion site should be evaluated in multiple planes to ensure clearance from underlying abdominal organs and detect any abdominal wall blood vessels along the anticipated needle trajectory. 8. We recommend that a needle insertion site should be marked with ultrasound immediately before performing the procedure, and the patient should remain in the same position between marking the site and performing the procedure. 9. We recommend that using real-time ultrasound guidance for paracentesis should be considered when the fluid collection is small or difficult to access. 10. We recommend that dedicated training sessions, including didactics, supervised practice on patients, and simulation-based practice, should be used to teach novices how to perform ultrasound-guided paracentesis. 11. We recommend that simulation-based practice should be used, when available, to facilitate acquisition of the required knowledge and skills to perform ultrasoundguided paracentesis. 12. We recommend that competence in performing ultrasound-guided paracentesis should be demonstrated prior to independently performing the procedure on patients.

Point-of-Care Ultrasound Improves Shared Diagnostic Understanding Between Patients and Providers.

OBJECTIVES: Point-of-care ultrasound (POCUS) has become an integral part of the physical examination. The effect on shared understanding of adding POCUS to the traditional examination is unknown, yet this is an often-described benefit of POCUS. The primary aim of this study was to determine whether the use of POCUS improves shared understanding between providers and patients about patients' diagnoses. METHODS: This was a prospective controlled trial involving a convenience sample of hospitalized adults. Providers in the control arm performed usual care without POCUS, whereas providers in the study arm had the option to add POCUS. Surveys were administered to the subjects and their providers with questions on patient understanding of symptoms, diagnosis, and main contributors to their health problem. Two independent physicians rated the degree of shared understanding between patient and provider surveys. RESULTS: Of the 64 patients enrolled in the study, 60 had complete data. There was increased shared understanding between providers and patients with respect to their diagnosis (POCUS 9.56 ± 0.63, non-POCUS 7.62 ± 1.63, P < 0.005) and main contributors (POCUS 9.65 ± 0.77, non-POCUS 8.30 ± 1.13, P < 0.005) in the POCUS arm compared with the non-POCUS arm. Patients also increased the self-rating of their understanding of their health problem in the POCUS arm. CONCLUSIONS: These findings suggest that using POCUS improves patients' understanding of the diagnostic process. POCUS may be uniquely poised to enhance patients' understanding of and engagement in that process.

Entrusting internal medicine residents to use point of care ultrasound: Towards improved assessment and supervision.

Background: Internal medicine physicians and trainees are increasingly using, and seeking training in, diagnostic point of care ultrasound (POCUS). Numerous internal medicine training programs have described their curricula, but little has been written about how learners should be assessed, supervised, and allowed to progress toward independent practice, yet these practices are imperative for safe and effective use. Entrustable professional activities (EPAs) offer a practical method to assess observable units of professional work and make supervision decisions. Methods: An EPA for POCUS is used as a framework to assess and determine appropriate levels of supervision in an internal medicine residency program. Results: All learners have been able to advance to level 2 with a mandatory introductory boot camp course. Learners have been able to advance to higher levels of independence, often after taking formal elective programmatic coursework. However, not all learners taking the same coursework have been granted the same level of independence. Conclusions: It is feasible to assess and supervise internal medicine residents' ability to use diagnostic point of care ultrasound using an EPA.

Evaluating a mobile application for improving clinical laboratory test ordering and diagnosis.

Objective: Mobile applications for improving diagnostic decision making often lack clinical evaluation. We evaluated if a mobile application improves generalist physicians' appropriate laboratory test ordering and diagnosis decisions and assessed if physicians perceive it as useful for learning. Methods: In an experimental, vignette study, physicians diagnosed 8 patient vignettes with normal prothrombin times (PT) and abnormal partial thromboplastin times (PTT). Physicians made test ordering and diagnosis decisions for 4 vignettes using each resource: a mobile app, PTT Advisor, developed by the Centers for Disease Control and Prevention (CDC)'s Clinical Laboratory Integration into Healthcare Collaborative (CLIHC); and usual clinical decision support. Then, physicians answered questions regarding their perceptions of the app's usefulness for diagnostic decision making and learning using a modified Kirkpatrick Training Evaluation Framework. Results: Data from 368 vignettes solved by 46 physicians at 7 US health care institutions show advantages for using PTT Advisor over usual clinical decision support on test ordering and diagnostic decision accuracy (82.6 vs 70.2% correct; P < .001), confidence in decisions (7.5 vs 6.3 out of 10; P < .001), and vignette completion time (3:02 vs 3:53 min.; P = .06). Physicians reported positive perceptions of the app's potential for improved clinical decision making, and recommended it be used to address broader diagnostic challenges. Conclusions: A mobile app, PTT Advisor, may contribute to better test ordering and diagnosis, serve as a learning tool for diagnostic evaluation of certain clinical disorders, and improve patient outcomes. Similar methods could be useful for evaluating apps aimed at improving testing and diagnosis for other conditions.

The Design and Evaluation of the Comprehensive Hospitalist Assessment and Mentorship with Portfolios (CHAMP) Ultrasound Program.

BACKGROUND: Literature supports the use of point-ofcare ultrasound performed by the treating hospitalist in the diagnosis of common diseases. There is no consensus on the training paradigm or the evaluation of skill retention for hospitalists. OBJECTIVE: To evaluate the effectiveness of a comprehensive bedside ultrasound training program with postcourse competency assessments for hospitalists. DESIGN: A retrospective report of a training program with 53 hospitalists. The program consisted of online modules, a 3-day in-person course, portfolios, 1-day refresher training, monthly scanning, and assessments. Hospitalists were rated by using similar pre- and postcourse competency assessments and self-rating parameters during the 3-day and refresher courses. SETTING: A large tertiary-care center. RESULTS: Skills increased after the 3-day course from a median preassessment score of 15% correct (interquartile range [IQR] 10%-25%) to a median postassessment score of 90% (IQR 80%-95%; P < .0001). At the time of the refresher course, the median precourse skills score had decreased to 65% correct (IQR 35%-90%), which improved to 100% postcourse (IQR 85%-100%; P < .0001). Skills scores decreased significantly less between the post 3-day course assessment and pre 1-day refresher course for hospitalists who completed portfolios (mean decrease 13.6% correct; P < .0001) and/or monthly scanning sessions (mean decrease 7.3% correct; P < .0001) compared with hospitalists who did not complete these items. CONCLUSIONS: A comprehensive longitudinal ultrasound training program including competency assessments improved ultrasound acquisition skills with hospitalists. Skill retention remained high in those who completed portfolios and/or monthly scanning sessions along with a 1-day in-person refresher course.
