Point-of-Care Ultrasound in Family Medicine Residencies 5-Year Update: A CERA Study.

BACKGROUND AND OBJECTIVES: In 2014, family medicine residency programs began to integrate point-of-care ultrasound (POCUS) into training, although very few had an established POCUS curriculum. This study aimed to evaluate the resources, barriers, and scope of POCUS training in family medicine residencies 5 years after its inception. METHODS: Questions regarding current training and use of POCUS were included in the 2019 Council of Academic Family Medicine Educational Research Alliance (CERA) survey of family medicine residency program directors, and results compared to similar questions on the 2014 CERA survey. RESULTS: POCUS is becoming a core component of family medicine training programs, with 53% of program directors reporting establishing or an established core curriculum. Only 11% of program directors have no current plans to add POCUS training to their program, compared to 41% in 2014. Despite this increase in training, the reported clinical use of POCUS remains uncommon. Only 27% of programs use six of the eight surveyed POCUS modalities more than once per year. The top three barriers to including POCUS in residency training in 2019 have not changed since 2014, and are (1) a lack of trained faculty, (2) limited access to equipment, and (3) discomfort with interpreting images without radiologist review. CONCLUSIONS: Training in POCUS has increased in family medicine residencies over the last 5 years, although practical use of this technology in the clinical setting may be lagging behind. Further research should explore how POCUS can improve outcomes and reduce costs in the primary care setting to better inform training for this technology.

Canadian national survey of family medicine residents on point-of-care ultrasound training.

OBJECTIVE: To assess the quality of point-of-care ultrasound (POCUS) training in family medicine residency programs and to obtain the opinions of current family medicine residents on the role of ultrasound in primary care. DESIGN: A 23-question online survey conducted using SurveyMonkey between March 15 and June 30, 2017. SETTING: Canada. PARTICIPANTS: All family medicine residents of the 17 Canadian family medicine residency programs were included in the study but all enhanced skills residents were excluded. MAIN OUTCOME MEASURES: The quality and relevance of POCUS to primary care as perceived by residents and reported in the survey. RESULTS: A total of 854 Canadian family medicine residents responded, for a national response rate of 32.3%. Most respondents (94.3%) believe that POCUS training should be included in family medicine residency programs; however, only 18.4% of respondents currently receive formal training within their residency. Among those without POCUS training, 91.7% are interested in receiving formal training and 29.7% resorted to taking external POCUS courses. Most (77.5%) would consider using ultrasound in their future practice if they were competent in POCUS. The most useful applications for family medicine were considered to be the FAST (Focused Assessment with Sonography in Trauma) examination for free fluid and ascites (95.1%), procedural guidance (92.4%), and identifying an intrauterine pregnancy (88.6%). CONCLUSION: This is the largest survey identifying the perceived needs of family medicine residents for POCUS. Very few Canadian family medicine residents currently receive POCUS training. Consistent with our recent family medicine program director survey, there is overwhelming interest by family medicine residents to begin incorporating POCUS training into the family medicine curriculum.

Canadian national survey of point-of-care ultrasound training in family medicine residency programs.

OBJECTIVE: To assess the current state of point-of-care ultrasound (POCUS) training in Canadian family medicine residency programs. DESIGN: Cross-sectional survey to evaluate POCUS education in accredited Canadian family medicine residency programs; only 1 completed survey was accepted per residency program. SETTING: Seventeen accredited Canadian family medicine residency programs. PARTICIPANTS: Fourteen directors of family medicine programs across Canada. MAIN OUTCOME MEASURES: Opinions of program directors in family medicine education on the relevance of POCUS in family medicine, and the role of POCUS training in family medicine residency programs. RESULTS: The Web-based, anonymous survey, which was completed during the months of March and April 2016, achieved a response rate of 82% (14 out of 17 program directors). About one-fifth (21%) of program directors reported having an established ultrasound curriculum. Almost all directors (93%) believed that POCUS teaching should be integrated into family medicine residency curricula. Barriers to establishing training included the following: lack of adequate equipment (57%), lack of instructors (57%), lack of available time in the curriculum (57%), and lack of funding available to support training (71%). Seventy-one percent of respondents believed that POCUS could be used in outpatient family medicine clinics to alter clinical decision making. Some potential benefits associated with POCUS in primary care include more rapid diagnosis, improved patient outcomes, and potential to reduce health care costs. CONCLUSION: Although only a few Canadian family medicine residency program directors reported actually having an established ultrasound curriculum, most of them believed that POCUS training should be offered to family medicine residents and that its use could positively affect primary care. A growing number of family medicine residency programs are considering incorporating ultrasound training into their curricula, but resource availability remains a considerable barrier to implementation.

Barriers to point-of-care ultrasound use in rural emergency departments.

Over the past few decades, point-of-care ultrasound (PoCUS) has come to play a major role in the practice of emergency medicine. Despite its numerous benefits, there has been a slow uptake of PoCUS use in rural emergency departments. Surveys conducted across Canada and the United States have identified a lack of equipment, training, funding, quality assurance, and an inability to maintain skills as major barriers to PoCUS use. Potential solutions include expanding residency training in ultrasound skills, extending funding for PoCUS training to rural physicians in practice, moving PoCUS training courses to rural sites, and creating telesonography training for rural physicians. With these barriers identified and solutions proposed, corrective measures must be taken so that the benefits of PoCUS are extended to patients in rural Canada where, arguably, it has the greatest potential for benefit when access to advanced imaging is not readily available.

Vision deficits precede structural losses in a mouse model of mitochondrial dysfunction and progressive retinal degeneration.

Current animal models of retinal disease often involve the rapid development of a retinal disease phenotype; however, this is at odds with age-related diseases that take many years to manifest clinical symptoms. The present study was performed to examine an apoptosis-inducing factor (Aif)-deficient model, the harlequin carrier mouse (X(hq)X), and determine how mitochondrial dysfunction and subsequent accelerated aging affect the function and structure of the mouse retina. Vision and eye structure for cohorts of 6 X(hq)X and 6 wild type mice at 3, 11, and 15 months of age were studied using in vivo electroretinography (ERG), and optical coherence tomography (OCT). Retinal superoxide levels were determined in situ using dihydroethidium (DHE) histochemistry. Retinal cell counts were quantified post mortem using hematoxylin and eosin (H&E) staining. ERG analysis of X(hq)X retinal function indicated a reduction in b-wave amplitude significant at 3 months of age (p < 0.05), declining further with age. However, retinal neuron counts demonstrated the absence of physical degeneration at 3 and 11 months of age despite significant reduction in ERG b-wave amplitude. Superoxide anion levels were elevated in the ganglion cell, inner nuclear and outer nuclear layers of the retina (p < 0.01, p < 0.01, and p < 0.001, respectively) of 11-month-old X(hq)X mice in comparison to wild type, preceding the structural losses observed at 15 mos. Early onset of retinal function deficits occurred independently of neuron loss. Changes in neurotransmitter localization in the stressed retina may account for the early and significant reduction in retinal function. This remodeling of retinal neurochemistry in response to stress may be a relevant mechanism in the progression of normal retinal aging and early stages of some retinal degenerative diseases.
