RESUMO
INTRODUCTION: In 2015, the Severe Sepsis and Early Septic Shock Management Bundle (SEP-1) tied hospital reimbursement to performance on a series of time sensitive indicators, including ordering blood cultures on patients with severe sepsis or septic shock. This metric could have broadly shaped ordering practices in the Emergency Department (ED), including for patients who did not have severe sepsis or septic shock. In this study, we sought to evaluate whether the frequency of blood culture orders on adult patients discharged from the ED changed after the SEP-1 metric, whether the rates of positivity for pathogens or contaminants changed after the SEP-1 metric, and whether similar changes were seen in orders for other laboratory tests. METHODS: This was a retrospective evaluation of blood culture orders from discharged adult ED patients from a suburban academic hospital between January 1, 2012 and June 30, 2019. We compared the number of blood cultures per discharged adult patient before and after the SEP-1 metric. We categorized each culture that grew an organism as a pathogen or a contaminant, and we compared rates of pathogen and contaminant growth before and after SEP-1. We compared rates of orders of blood cultures and lactates as labs related to SEP-1 with rates of orders of D-dimers, lipases, human chorionic gonadotropins (HCGs), and brain natriuretic peptides (BNPs) as labs unrelated to SEP-1 before and after the implementation of the SEP-1 metric. RESULTS: There were 144,343 adult patients discharged from the ED during the study period. A total of 6754 blood cultures were drawn from 3827 of those patient visits. The rate increased from 43.1 cultures per 1000 discharged patients before the SEP-1 metric to 75.9 blood cultures per 1000 discharged patients, an increase of 76.2% (p < 0.001). The cultures had a decreased rate of positivity (from 3.93% before SEP-1 to 3.03% after SEP-1, p = 0.044) and an unchanged rate of blood cultures resulting in a contaminant (2.49% to 1.85%, p = 0.071). Overall, orders of the labs unrelated to SEP-1 increased by an average of 16.8% after the SEP-1 metric and orders of the labs related to SEP-1 increased by an average of 81.0%. CONCLUSION: After the SEP-1 bundle, blood cultures were ordered more frequently on discharged ED patients. These cultures had a lower rate of positivity for pathogens and an unchanged rate of growth of contaminants. This increase was not matched by a similar increase in other labs. Taken together, these findings suggest that the SEP-1 metric had the unintended consequence of increasing orders of blood cultures on patients healthy enough to be discharged from the ED.

Sepsis is a condition characterized by life-threatening organ dysfunction caused by a dysregulated host response to infection. The emergency department (ED) serves as a crucial entry point for patients presenting with sepsis. Given the heterogeneous presentation and high mortality rate associated with sepsis and septic shock, several clinical controversies have emerged in the management of sepsis. These include the use of novel therapeutic agents like angiotensin II, hydrocortisone, ascorbic acid, thiamine ("HAT") therapy, and levosimendan, Additionally, controversies with current treatments in vasopressor dosing, and the use of and balanced or unbalanced crystalloid are crucial to consider. The purpose of this review is to discuss clinical controversies in the management of septic patients, including the use of novel medications and dosing strategies, to assist providers in appropriately determining what treatment strategy is best suited for patients.

BACKGROUND: A multidisciplinary team at a major academic medical center established an Acutely Decompensated Heart Failure Clinical Pathway (ADHFCP) program to reduce inpatient readmission rates among patients with heart failure which, among several interventions, included an immediate consultation from a cardiologist familiar with an ADHFCP patient when the patient presented at the Emergency Department (ED). This study analyzed how that program impacted utilization of services in the ED and its subsequent effect on rates of admission from the ED and on disposition times. METHODS: ADHFCP inpatient visits were retrospectively risk stratified and matched with non-program inpatient visits to create a control group. A Cox survival model analyzed the ADHFCP's impact on patients' likelihood to visit the ED. Multivariable ANOVA evaluated the impact of the program on the patients' likelihood of being admitted when presenting at the ED. The ADHFCP's impact on bed-to-disposition time in the ED was evaluated by Wilcoxon's rank-sum test, as were doses of diuretics administered in the ED. RESULTS: The survival analysis showed no impact of the ADHFCP on patients' likelihood of visiting the ED, but ADHFCP patients presenting to the ED were 13.1 (95% CI: 3.6-22.6) percentage points less likely to be admitted. There was no difference in bed-to-disposition times, but ADHFCP patients received diuretics more frequently and at higher doses. CONCLUSIONS: Improved communication between cardiologists and ED physicians through the establishment of an explicit pathway to coordinate the care of heart failure patients may decrease that population's likelihood of admission without increasing ED disposition times.

Small numbers of graduates from few medical schools, and emigration of graduates to other countries, contribute to low physician presence in sub-Saharan Africa. The Sub-Saharan African Medical School Study examined the challenges, innovations, and emerging trends in medical education in the region. We identified 168 medical schools; of the 146 surveyed, 105 (72%) responded. Findings from the study showed that countries are prioritising medical education scale-up as part of health-system strengthening, and we identified many innovations in premedical preparation, team-based education, and creative use of scarce research support. The study also drew attention to ubiquitous faculty shortages in basic and clinical sciences, weak physical infrastructure, and little use of external accreditation. Patterns recorded include the growth of private medical schools, community-based education, and international partnerships, and the benefit of research for faculty development. Ten recommendations provide guidance for efforts to strengthen medical education in sub-Saharan Africa.

BACKGROUND: Sub-Saharan Africa suffers a disproportionate share of the world's burden of disease while having some of the world's greatest health care workforce shortages. Doctors are an important component of any high functioning health care system. However, efforts to strengthen the doctor workforce in the region have been limited by a small number of medical schools with limited enrolments, international migration of graduates, poor geographic distribution of doctors, and insufficient data on medical schools. The goal of the Sub-Saharan African Medical Schools Study (SAMSS) is to increase the level of understanding and expand the baseline data on medical schools in the region. METHODS: The SAMSS survey is a descriptive survey study of Sub-Saharan African medical schools. The survey instrument included quantitative and qualitative questions focused on institutional characteristics, student profiles, curricula, post-graduate medical education, teaching staff, resources, barriers to capacity expansion, educational innovations, and external relationships with government and non-governmental organizations. Surveys were sent via e-mail to medical school deans or officials designated by the dean. Analysis is both descriptive and multivariable. RESULTS: Surveys were distributed to 146 medical schools in 40 of 48 Sub-Saharan African countries. One hundred and five responses were received (72% response rate). An additional 23 schools were identified after the close of the survey period. Fifty-eight respondents have been founded since 1990, including 22 private schools. Enrolments for medical schools range from 2 to 1800 and graduates range from 4 to 384. Seventy-three percent of respondents (n = 64) increased first year enrolments in the past five years. On average, 26% of respondents' graduates were reported to migrate out of the country within five years of graduation (n = 68). The most significant reported barriers to increasing the number of graduates, and improving quality, related to infrastructure and faculty limitations, respectively. Significant correlations were seen between schools implementing increased faculty salaries and bonuses, and lower percentage loss of faculty over the previous five years (P = 0.018); strengthened institutional research tools (P = 0.00015) and funded faculty research time (P = 0.045) and greater faculty involvement in research; and country compulsory service requirements (P = 0.039), a moderate number (1-5) of post-graduate medical education programs (P = 0.016) and francophone schools (P = 0.016) and greater rural general practice after graduation. CONCLUSIONS: The results of the SAMSS survey increases the level of data and understanding of medical schools in Sub-Saharan Africa. This data serves as a baseline for future research, policies and investment in the health care workforce in the region which will be necessary for improving health.
RESUMO
OBJECTIVE: To compare outcomes following percutaneous cholecystostomy drain placement based on presence or absence of Tokyo Guidelines diagnostic criteria for acute cholecystitis. METHODS: Chart review was performed to identify the presence or absence of Tokyo Guidelines diagnostic criteria for acute cholecystitis in 146 patients who underwent percutaneous cholecystostomy between 2012 and 2015. Those who met criteria were compared to those who did not in terms of demographics, laboratory values, drain indwelling time, treatment response, eventual surgical management, and 30-day mortality. RESULTS: 94 patients (64%) met Tokyo Guidelines diagnostic criteria, while 52 did not (36%). Patients within criteria had a shorter mean length of stay (13.5 days vs 18.9 days), were more likely to have a positive gallbladder fluid culture (64.5% vs 28.6%), demonstrated greater response to treatment (87.2% vs 32.7%), and had lower 30-day mortality (6.4% vs 37.8%). There was no significant difference in terms of ICU requirement (38.3% vs 38.9%), mean drain indwelling time (58.8 days vs 65.3 days), eventual laparoscopic cholecystectomy (40.4% vs 25.0%), or open cholecystectomy performed (9.5% vs 9.6%). CONCLUSION: Patients outside of Tokyo Guidelines diagnostic criteria for acute cholecystitis were less likely to respond to treatment with percutaneous cholecystostomy and had worse outcomes. Further research may be indicated to better define the indications for percutaneous cholecystostomy placement in this group.

INTRODUCTION: Most residents have limited education or exposure to health policy during residency. AIMS: We developed a course to (1) educate residents on health policy topics applicable to daily physician practice; (2) expose residents to health policy careers through visits with policy makers and analysts; (3) promote personal engagement in health policy. SETTING: Residents registered for a 3-week elective offered twice annually through the George Washington University Department of Health Policy. PROGRAM DESCRIPTION: The course format includes: daily required readings and small-group seminars with policy experts, interactive on-site visits with policy makers, and final team presentations to senior faculty on topical health policy issues. PROGRAM EVALUATION: One hundred thirty residents from 14 specialties have completed the course to date. Seventy completed our post-course survey. Most participants [59 (84%)] felt the course was very or extremely helpful. Participant self-ratings increased from pre- to post-course in overall knowledge of health policy [2 (3%) good or excellent before, 58 (83%) after], likelihood of teaching policy concepts to peers [20 (25%) vs. 62 (86%)], and likelihood of pursuing further health policy training [28 (37%) vs. 56 (82%)]. CONCLUSIONS: This 3-week elective in health policy improves self-reported knowledge and interest in health policy research, advocacy, and teaching.

Successful application of living cells in regenerative medicine requires an understanding of how tissue structure relates to organ function. There is growing evidence that presentation of extracellular cues in a three-dimensional (3D) context can fundamentally alter cellular responses. Thus, microenvironment studies that previously were limited to adherent two-dimensional (2D) cultures may not be appropriate for many cell types. Here we present a method for the rapid formation of reproducible, high-resolution 3D cellular structures within a photopolymerizable hydrogel using dielectrophoretic forces. We demonstrate the parallel formation of >20,000 cell clusters of precise size and shape within a thin 2-cm(2) hydrogel and the maintenance of high cell viability and differentiated cell markers over 2 weeks. By modulating cell-cell interactions in 3D clusters, we present the first evidence that microscale tissue organization regulates bovine articular chondrocyte biosynthesis. This platform permits investigation of tissue architecture in other multicellular processes, from embryogenesis to regeneration to tumorigenesis.
