BACKGROUND:Portal vein thrombosis (PVT) develops in cirrhotic patients because of stagnation of blood flow. Transjugular intrahepatic portosystemic shunt (TIPS) creates a low-resistance conduit that restores portal venous patency and blood flow. AIM/OBJECTIVE:The effect of PVT on transplant-free survival in cirrhotic patients undergoing TIPS creation was evaluated. PATIENTS AND METHODS/METHODS:A multicenter, retrospective cohort study of patients who underwent TIPS creation for cirrhotic portal hypertension was carried out. A Cox model with propensity score adjustment was developed to evaluate the effect of PVT on 90-day and 3-year transplant-free survival. A subgroup analysis examining mortality of those with superior and distal PVT was also carried out. RESULTS:A total of 252 consecutive TIPS creations were assessed, including 65 in patients with PVT. Survival of patients with high Model for End-stage Liver Disease scores (≥18) and PVT was not statistically different compared with patients with low Model for End-stage Liver Disease scores (<18) and no PVT at 90 days (P=0.46) and 3 years (P=0.42). Those with inferior PVT had improved 90-day and 3-year survival both compared with patients with a superior PVT and those without a PVT (P<0.01, all cases). CONCLUSION/CONCLUSIONS:The presence of PVT does not impair the prognosis of patients following TIPS creation, particularly in patients with distal portal occlusion.

Aim: Naltrexone is first-line pharmacotherapy for alcohol use disorders (AUD). Oral naltrexone (ONTX) is under-prescribed in primary care and possibly limited by poor adherence. Monthly injectable extended-release naltrexone (XR-NTX) may improve rates of medication adherence, retention, good clinical outcomes (Aim 1), and cost savings (Aim 2). Methods: This is an on-going randomized, open-label, comparative effectiveness trial of 24 weeks of XR-NTX vs. O-NTX as AUD treatment in primary care at a public hospital in New York City. Adults (>18 yo) with a DSM-V diagnosis of AUD randomized to XR-NTX (380 mg/month) vs. O-NTX (50-100 mg/day).Medical Management visits occur biweekly (weeks 1-8), then monthly.Major research assessments occur at baseline, weeks 13, 25, 48. The primary outcome is a Good Clinical Outcome (GCO) across weeks 5-24: abstinence or moderate drinking and 0-2 days of heavy drinking per month. This preliminary, descriptive analysis presentsWeek 0-5 results among all participants. Results: N = 237 participants were randomized from 6/14-9/17: mean age 48.5 (SD = 10.6); 71% male; 54% AA, 21%Hispanic; 41% employed, 81%reported other lifetime substance use. Mean AUDIT scores (instrument range 0-40) at baseline: 24.2 (SD = 8.0); mean OCDS (range 0-40) scores 17.1 (SD = 8.1); mean drinks/day 9.6 (SD = 11.6) with 29%abstinent vs. 61% heavy drinking days. Medication induction was robust, 115 of 117 (98.2%) initiating XR-NTX and 120 (100%) filled or received an initial O-NTX prescription. The GCO was reported by 41%XR-NTX and 47%ONTX atWeek 5. DuringWeek 1-5, mean drinks/day were 3.1 (SD = 6.1), 63% abstinent/22%heavy drinking days for XR-NTX; 2.4 (SD = 4.03), 61%abstinent/22%heavy drinking days for O-NTX. 62%received XR-NTX injection #2 and 67%received O-NTXmonthly refill #2. Adherence self-report for O-NTX at Week 5 indicated moderate average daily adherence,MMAS-8 mean (range <6 low, 6 to <8 moderate, =8 high) score 6.13 (SD = 3.02). Conclusion: This on-going XR vs. oral naltrexone alcohol primary care treatment trial recruited a primarily male, unemployed, ethnic minority adult population. Initial acceptance of both XR and ONTX was high. Primary outcomes will focus on drinking reductions and cost and value comparisons during weeks 5-24

We performed whole-genome sequencing on 170 clinical carbapenemase-producing Enterobacter spp. isolates collected globally during 2008-2014. The most common carbapenemase was VIM, followed by New Delhi metallo-β-lactamase (NDM), Klebsiella pneumoniae carbapenemase, oxacillin 48, and IMP. The isolates were of predominantly 2 species (E. xiangfangensis and E. hormaechei subsp. steigerwaltii) and 4 global clones (sequence type [ST] 114, ST93, ST90, and ST78) with different clades within ST114 and ST90. Particular genetic structures surrounding carbapenemase genes were circulating locally in various institutions within the same or between different STs in Greece, Guatemala, Italy, Spain, Serbia, and Vietnam. We found a common NDM genetic structure (NDM-GE-U.S.), previously described on pNDM-U.S. from Klebsiella pneumoniae ATCC BAA-214, in 14 different clones obtained from 6 countries spanning 4 continents. Our study highlights the importance of surveillance programs using whole-genome sequencing in providing insight into the molecular epidemiology of carbapenemase-producing Enterobacter spp.

BACKGROUND:Patient-centered medical homes have made great strides providing comprehensive care for patients with chronic conditions, but may not provide sufficient support for patients at highest risk for acute care use. To address this, the Veterans Health Administration (VHA) initiated a five-site demonstration project to evaluate the effectiveness of augmenting the VA's Patient Aligned Care Team (PACT) medical home with PACT Intensive Management (PIM) teams for Veterans at highest risk for hospitalization. METHODS/DESIGN/METHODS:Researchers partnered with VHA leadership to design a mixed-methods prospective multi-site evaluation that met leadership's desire for a rigorous evaluation conducted as quality improvement rather than research. We conducted a randomized QI evaluation and assigned high-risk patients to participate in PIM and compared them with high-risk Veterans receiving usual care through PACT. The summative evaluation examines whether PIM: 1) decreases VHA emergency department and hospital use; 2) increases satisfaction with VHA care; 3) decreases provider burnout; and 4) generates positive returns on investment. The formative evaluation aims to support improved care for high-risk patients at demonstration sites and to inform future initiatives for high-risk patients. The evaluation was reviewed by representatives from the VHA Office of Research and Development and the Office of Research Oversight and met criteria for quality improvement. DISCUSSION/CONCLUSIONS:VHA aims to function as a learning organization by rapidly implementing and rigorously testing QI innovations prior to final program or policy development. We observed challenges and opportunities in designing an evaluation consistent with QI standards and operations priorities, while also maintaining scientific rigor. TRIAL REGISTRATION/BACKGROUND:This trial was retrospectively registered at ClinicalTrials.gov on April 3, 2017: NCT03100526. Protocol v1, FY14-17.

BACKGROUND:The near-universal prevalence of electronic health records (EHRs) has made the utilization of clinical decision support systems (CDSS) an integral strategy for improving the value of laboratory ordering. Few studies have examined the effectiveness of nonintrusive CDSS on inpatient laboratory utilization in large academic centres. METHODS:Red blood cell folate, hepatitis C virus viral loads and genotypes, and type and screens were selected for study. We incorporated the appropriate indications for these labs into text that accompanied the laboratory orders in our hospital's EHR. Providers could proceed with the order without additional clicks. An interrupted time-series analysis was performed, and the primary outcome was the rate of tests ordered on all inpatient medicine floors. RESULTS:The rate of folate tests ordered per monthly admissions showed no significant level change at the time of the intervention with only a slight decrease in rate of 0.0109 (P = .07). There was a 43% decrease in the rate of hepatitis C virus tests per monthly admissions immediately after the intervention with a decrease of 0.0135 tests per monthly admissions (P = .02). The rate of type and screens orders per patient days each month had a significant downward trend by 0.114 before the intervention (P = .04) but no significant level change at the time of the intervention or significant change in rate after the intervention. DISCUSSION/CONCLUSIONS:Our study suggests that nonintrusive CDSS should be evaluated for individual laboratory tests to ensure only effective alerts continue to be used so as to avoid increasing EHR fatigue.

In North Carolina, our public health infrastructure consists of a state health department and 85 local health departments representing all 100 counties. The state health department, local health departments, health systems, and clinical providers work literally and figuratively as a team to improve the health of our citizens. In this article, we provide examples of the critical role of public health practitioners as part of the broader team addressing health, specifically in the areas of chronic disease, communicable disease, oral health, environmental health, and maternal and child health.

In December 2017, the National Academy of Neuropsychology convened an interorganizational Summit on Population Health Solutions for Assessing Cognitive Impairment in Geriatric Patients in Denver, Colorado. The Summit brought together representatives of a broad range of stakeholders invested in the care of older adults to focus on the topic of cognitive health and aging. Summit participants specifically examined questions of who should be screened for cognitive impairment and how they should be screened in medical settings. This is important in the context of an acute illness given that the presence of cognitive impairment can have significant implications for care and for the management of concomitant diseases as well as pose a major risk factor for dementia. Participants arrived at general principles to guide future screening approaches in medical populations and identified knowledge gaps to direct future research. Key learning points of the summit included: recognizing the importance of educating patients and healthcare providers about the value of assessing current and baseline cognition;emphasizing that any screening tool must be appropriately normalized and validated in the population in which it is used to obtain accurate information, including considerations of language, cultural factors, and education; andrecognizing the great potential, with appropriate caveats, of electronic health records to augment cognitive screening and tracking of changes in cognitive health over time.

BACKGROUND:Two dominant themes face medical education: developing integrated curricula and improving the undergraduate medical education (UME) to graduate medical education (GME) transition. An innovative solution to both of these challenges at the Zucker School of Medicine has been the application of the cognitive apprenticeship framework in requiring emergency medical technician (EMT) certification during the first course in medical school as the core on which to build an integrated curriculum and provide entrustable clinical skills. METHODS:Beginning with the Class of 2011, student feedback about the short-term impact of the experience was collected annually. In addition, perceptions of near graduates and alumni were surveyed in 2017 to explore the long-term impact of the experience. Theme analysis was conducted via inductive coding. RESULTS:Both first-year and more experienced learners report the value of the EMT curriculum as an integrated component of the first course of medical school. Reported positive long-term impacts included the first-hand observation of social determinants of health and interprofessionalism. Negative comments by early learners focused on course logistics, whereas older learners recalled the variability of clinical experiences during ambulance runs. CONCLUSIONS:The integration of the EMT curriculum as a core component of the first course serves multiple purposes: 1) it provides the foundation of a spiral learning approach; 2) it contextualizes the basic sciences within clinical practice; 3) it provides opportunities for students to engage in authentic clinical activities under the guidance of mentors; 4) it introduces students to the interdisciplinary nature of medicine; and 5) it serves as the first entrustable professional activity (EPA) for our students.
