Prehospital Ultrasound Use to Guide Emergent Pericardiocentesis: A Case Report.

Point-of-care ultrasound (POCUS) has been shown to be a valuable tool in the management of acutely ill patients in the prehospital setting. POCUS not only has utility from a diagnostic perspective but also has been shown to reduce the rate of complications from otherwise traditionally "blind" procedures, such as pericardiocentesis. This case report highlights the utility of POCUS in the prehospital setting to guide emergent pericardiocentesis to treat cardiac tamponade. The applicability of various approaches to ultrasound-guided pericardiocentesis is also discussed.

Prehospital Cardiac Ultrasound to Confirm Mechanical Capture in Emergency Transcutaneous Pacing: A Case Report.

Point-of-care ultrasound (POCUS) is a safe diagnostic tool that clinicians use to rapidly evaluate critically ill patients.1 POCUS has expanded into the prehospital setting and has been demonstrated to be accurate, feasible, and helpful in guiding clinical decision making.2-4 Additionally, the American College of Emergency Physicians recommends the use of echocardiography to evaluate for ventricular activity in the setting of cardiac arrest.5 There is minimal evidence regarding the use of POCUS to confirm mechanical capture in patients undergoing transcutaneous pacing. This case report highlights the use of POCUS in a patient with bradyasystolic cardiac arrest requiring transcutaneous pacing. Despite electrical capture, the patient had absent central pulses; however, POCUS demonstrated ventricular contractions, indicating mechanical capture. This suggests a role for POCUS for the evaluation of mechanical capture in patients undergoing cardiac pacing.

A pilot study of a Community Health Agent-led type 2 diabetes self-management program using Motivational Interviewing-based approaches in a public primary care center in São Paulo, Brazil.

BACKGROUND: Rates of noncommunicable diseases (NCDs) such as type 2 diabetes are escalating in low and middle-income countries such as Brazil. Scalable primary care-based interventions are needed to improve self-management and clinical outcomes of adults with diabetes. This pilot study examines the feasibility, acceptability, and outcomes of training community health agents (CHAs) in Motivational Interviewing (MI)-based counseling for patients with poorly controlled diabetes in a primary care center in São Paulo, Brazil. METHODS: Nineteen salaried CHAs participated in 32 h of training in MI and behavioral action planning. With support from booster training sessions, they used these skills in their regular monthly home visits over a 6 month period with 57 diabetes patients with baseline HbA1cs > 7.0%. The primary outcome was patients' reports of the quality of diabetes care as measured by the Portuguese version of the Patient Assessment of Chronic Illness Care (PACIC) scale. Secondary outcomes included changes in patients' reported diabetes self-management behaviors and in A1c, blood pressure, cholesterol and triglycerides. We also examined CHAs' fidelity to and experiences with the intervention. RESULTS: Patients reported improvements over the 6 month period in quality of diabetes care received (PACIC score improved 33 (+/-19) to 68 (+/-21) (p < .001)). They reported increases in physical activity (p = .001), consumption of fruits and vegetables (p < .001) and medication adherence (p = .002), but no decreases in consumption of high-fat foods (p = .402) or sweets (p = .436). Participants had mean 6-month A1c levels 0.34% points lower than at baseline (p = .08) and improved mean LDL (-16.1 mg/dL, p = .005) and triglyceride levels (-38.725 mg/dL, p = .002). Of the 16 CHAs observed in fidelity assessments, 13 were categorized as medium- or high-performing on MI skills, while 3 were low-performing. CHAs expressed enthusiasm about learning new skills, and many described a shift from advice-giving to encouraging patients to define their own goals. CONCLUSION: In resource-scarce settings, it is essential to fully utilize existing primary care resources to stem the epidemic of diabetes and other NCDs. Our pilot results support the potential of training CHAs to incorporate effective diabetes self-management support into their routine patient encounters.

Doctors of tomorrow: An innovative curriculum connecting underrepresented minority high school students to medical school.

BACKGROUND: Racial minorities continue to be underrepresented in medicine (URiM). Increasing provider diversity is an essential component of addressing disparity in health delivery and outcomes. The pool of students URiM that are competitive applicants to medical school is often limited early on by educational inequalities in primary and secondary schooling. A growing body of evidence recognizing the importance of diversifying health professions advances the need for medical schools to develop outreach collaborations with primary and secondary schools to attract URiMs. The goal of this paper is to describe and evaluate a program that seeks to create a pipeline for URiMs early in secondary schooling by connecting these students with support and resources in the medical community that may be transformative in empowering these students to be stronger university and medical school applicants. METHODS: The authors described a medical student-led, action-oriented pipeline program, Doctors of Tomorrow, which connects faculty and medical students at the University of Michigan Medical School with 9th grade students at Cass Technical High School (Cass Tech) in Detroit, Michigan. The program includes a core curriculum of hands-on experiential learning, development, and presentation of a capstone project, and mentoring of 9th grade students by medical students. Cass Tech student feedback was collected using focus groups, critical incident written narratives, and individual interviews. Medical student feedback was collected reviewing monthly meeting minutes from the Doctors of Tomorrow medical student leadership. Data were analyzed using thematic analysis. RESULTS: Two strong themes emerged from the Cass Tech student feedback: (i) Personal identity and its perceived effect on goal achievement and (ii) positive affect of direct mentorship and engagement with current healthcare providers through Doctors of Tomorrow. A challenge noted by the medical students was the lack of structured curriculum beyond the 1st year of the program; however, this was complemented by their commitment to the program for continued longitudinal development. DISCUSSION: The authors propose that development of outreach pipeline programs that are context specific, culturally relevant, and established in collaboration with community partners have the potential to provide underrepresented students with opportunities and skills early in their formative education to be competitive applicants to college and ultimately to medical school.

Emergency Medicine Resident Needs Assessment and Preferences for a High-value Care Curriculum.

Introduction: Consideration of the cost of care and value in healthcare is now a recognized element of physician training. Despite the urgency to educate trainees in high-value care (HVC), educational curricula and evaluation of these training paths remain limited, especially with respect to emergency medicine (EM) residents. We aimed to complete a needs assessment and evaluate curricular preferences for instruction on HVC among EM residents. Methods: This was a qualitative, exploratory study using content analysis of two focus groups including a total of eight EM residents from a single Midwestern EM residency training program. Participants also completed a survey questionnaire. Results: There were two themes. Within the overall theme of resident experience with and perception of HVC, we found five sub-themes: 1) understanding of HVC focuses on diagnosis and decision-making; 2) concern about patient costs, including the effects on patients' lives and their ability to engage with recommended outpatient care; 3) conflict between internal beliefs and external expectations, including patients' perceptions of value; 4) approach to HVC changes with increasing clinical experience; and 5) slow-moving, political discussion around HVC. Within the overall theme of desired education and curricular design, we identified four sub-themes: 1) limited prior education on HVC and health economics; 2) motivation to receive training on HVC and health economics; 3) desire for discussion-based format for HVC curriculum; and 4) curriculum targeted to level of training. Respondents indicated greatest acceptability of interactive, discussion-based formats. Discussion: We conducted a targeted needs assessment for HVC among EM residents. We identified broad interest in the topic and limited self-reported baseline knowledge. Curricular content may benefit from incorporating resident concerns about patient costs and conflict between external expectations and internal beliefs about HVC. Curricular design may benefit from a focus on interactive, discussion-based modalities and tailoring to the learner's level of training.

Use of Acellular Dermal Matrix in Postmastectomy Breast Reconstruction: Are All Acellular Dermal Matrices Created Equal?

BACKGROUND: AlloDerm and FlexHD are two types of acellular dermal matrices commonly used in implant-based reconstruction. Although the use of acellular dermal matrix has revolutionized immediate breast reconstruction in the setting of breast cancer, it remains unclear which type of acellular dermal matrix is best. The purpose of this retrospective cohort study was to compare postoperative complication rates between these two types of acellular dermal matrix. METHODS: The authors reviewed the records of all patients who underwent implant-based breast reconstruction at their institution between 1998 and 2013. Dependent variables of seroma, hematoma, infection, delayed wound healing, implant exposure, and return to the operating room for management of complications were recorded. RESULTS: A total of 309 consecutive patients were identified. Of these, AlloDerm was used in 123 patients (39.8 percent) and FlexHD was used in 186 patients (60.2 percent). Most patients in the authors' cohort underwent immediate reconstruction [n = 288 (93.2 percent)], with a mean follow-up of 20.0 months. Patients receiving AlloDerm were half as likely to have major infections compared with patients receiving FlexHD (OR, 0.50; 95 percent CI, 0.16 to 1.00; p < 0.05). The rates of other complications were similar between the two groups. CONCLUSION: There are significantly increased odds of a major infection in patients who undergo implant-based breast reconstruction using FlexHD compared with AlloDerm.
