Using Community Paramedicine to Treat Hepatitis C Virus in Upstate South Carolina.

OBJECTIVES: Hepatitis C virus (HCV) is an infection of the liver that can lead to significant liver damage and hepatocellular carcinoma. Individuals born between 1945 and 1965 and individuals with intravenous drug use represent the largest HCV demographics and often experience barriers to treatment. In this case series, we discuss a novel partnership between community paramedics (CPs), HCV care coordinators, and an infectious disease physician to provide HCV treatment to individuals with barriers accessing care. METHODS: Three patients tested positive for HCV within a large hospital system in the upstate region of South Carolina. All of the patients were contacted to discuss their results and scheduled for treatment by the hospital's HCV care coordination team. Patients who expressed barriers to attending in-person appointments or were lost to follow-up were offered a telehealth appointment facilitated by CPs performing a home visit with the added ability to draw blood and perform a physical assessment guided by the infectious disease physician. All of the patients were eligible for and prescribed treatment. The CPs assisted with follow-up visits, blood draws, and other patient needs. RESULTS: Two of the three patients connected to care had an undetectable HCV viral load following 4 weeks of treatment, whereas the third was undetectable after 8 weeks. Only one patient reported a mild headache that was potentially linked to the medication, whereas the others did not report any adverse effects. CONCLUSIONS: This case series highlights the barriers experienced by some HCV-positive patients and a distinctive plan to address impediments to access for HCV treatment.

Mobile integrated health to reduce post-discharge acute care visits: A pilot study.

BACKGROUND: Mobile Integrated Health (MIH) leverages specially trained paramedics outside of emergency response to bridge gaps in local health care delivery. STUDY OBJECTIVE: To evaluate the efficacy of a MIH led transitional care strategy to reduce acute care utilization. METHODS: This was a retrospective cohort analysis of a quality improvement pilot of patients from an urban, single county EMS, MIH transitional care initiative. We utilized a paramedic/social worker (or social care coordinator) dyad to provide in home assessments, medication review, care coordination, and improve access to care. The primary outcome compared acute care utilization (ED visits, observation stays, inpatient visits) 90days before MIH intervention to 90days after. RESULTS: Of the 203 patients seen by MIH teams, inpatient utilization decreased significantly from 140 hospitalizations pre-MIH to 26 post-MIH (83% reduction, p=0.00). ED and observation stays, however, increased numerically, but neither was significant. (ED 18 to 19 stays, p=0.98; observation stays 95 to 106, p=0.30) Primary care visits increased 15% (p=0.11). CONCLUSION: In this pilot before/after study, MIH significantly reduces acute care hospitalizations.

Survey of Emergency Department staff on disaster preparedness and training for Ebola virus disease.

INTRODUCTION: In the domestic response to the outbreak of Ebola virus disease from 2013 to 2015, many US hospitals developed and implemented specialized training programs to care for patients with Ebola. This research reports on the effects of targeted training on Emergency Department (ED) staff's Ebola-related perceptions and attitudes. METHODS: One hundred fifty-nine members of the UNC Health Care System ED staff participated in a voluntary cross-sectional, anonymous Web survey administered using a one-time "post then pre" design. Participants responded to questions about risk, roles, willingness to provide care, preparedness, and the contributions of media, training, or time to opinion change using a Likert agree-disagree scale. The authors conducted t test comparisons of Likert responses to pretraining and post-training attitudes about Ebola preparedness. The authors conducted multinomial logistic regression analyses of index scores of change and positivity of responses, controlling for the effects of independent variables. RESULTS: ED staff's opinions supported training; 73 percent felt all workers should receive Ebola education, 60 percent agreed all hospitals should prepare for Ebola, 66 percent felt UNC was better prepared, and 66 percent felt it had done enough to be ready for an Ebola case. Most staff (79 percent) said they had gotten more training for Ebola than for other disease outbreaks; 58 percent had experienced prior epidemics. After training, workers' attitudes were more positive about Ebola preparation including perceived risk of transmission, readiness and ability to manage a patient case, understanding team roles, and trust in both personal protective equipment and the hospital system's preparations (13 measures, p < 0.0001 to p < 0.001). Overall, total opinion indices also changed significantly over the training period (Mean Difference [MD] = 17.45, SD = 9.89) and in the intended positive direction (MD = 15.80, SD = 0.91, p < 0.0001). Positive change and overall change from pre to post were significantly associated with more hours of training (p = 0.003). Despite different occupations, mean scores were similar. Staff rated training most important and media least important, as the sources of change in their attitudes (p < 0.0001). CONCLUSIONS: These findings suggest that diseasespecific training for novel pathogens such as Ebola may result in positive staff perceptions of self-efficacy and occupational efficacy to treat potentially infected patients in the ED setting. Training, in this case, outweighed media content in changing staff perceptions of Ebola management.

Altered enteric microbiota ecology in interleukin 10-deficient mice during development and progression of intestinal inflammation.

Inflammatory bowel diseases (IBD) result from dysregulated immune responses toward microbial and perhaps other luminal antigens in a genetically susceptible host, and are associated with altered composition and diversity of the intestinal microbiota. The interleukin 10-deficient (IL-10 (-/-) ) mouse has been widely used to model human IBD; however the specific alterations that occur in the intestinal microbiota of this mouse model during the onset of colonic inflammation have not yet been defined. The aim of our study was to define the changes in diversity and composition that occur in the intestinal microbiota of IL-10 (-/-) mice during the onset and progression of colonic inflammation. We used high throughput sequencing of the 16S rRNA gene to characterize the diversity and composition of formerly germ-free, wild-type and IL-10 (-/-) mice associated with the same intestinal microbiota over time. Following two weeks of colonization with a specific pathogen-free (SPF) microbiota we observed a significant increase in the diversity and richness of the intestinal microbiota of wild-type mice. In contrast, a progressive decrease in diversity and richness was observed at three and four weeks in IL-10 (-/-) mice. This decrease in diversity and richness was mirrored by an increase in Proteobacteria and Escherichia coli in IL-10 (-/-) mice. An increase in E. coli was also observed in conventionally raised IL-10 (-/-) mice at the point of colonic inflammation. Our data reports the sequential changes in diversity and composition of the intestinal microbiota in an immune-mediated mouse model that may help provide insights into the primary vs. secondary role of dysbiosis in human IBD patients.

Fecal protease activity is associated with compositional alterations in the intestinal microbiota.

OBJECTIVE: Intestinal proteases carry out a variety of functions in the gastrointestinal (GI) tract. Studies have reported that elevated enteric proteases in patients with GI disease can alter intestinal physiology, however the origin (human vs. microbial) of elevated proteases in patients with GI disease is unclear. AIM: The aim of this study was to investigate the association between protease activity and the microbiota in human fecal samples. DESIGN: In order to capture a wide range of fecal protease (FP) activity stool samples were collected from 30 IBS patients and 24 healthy controls. The intestinal microbiota was characterized using 454 high throughput pyro-sequencing of the 16S rRNA gene. The composition and diversity of microbial communities were determined and compared using the Quantitative Insights Into Microbial Ecology (QIIME) pipeline. FP activity levels were determined using an ELISA-based method. FP activity was ranked and top and bottom quartiles (n=13 per quartile) were identified as having high and low FP activity, respectively. RESULTS: The overall diversity of the intestinal microbiota displayed significant clustering separation (p = 0.001) between samples with high vs. low FP activity. The Lactobacillales, Lachnospiraceae, and Streptococcaceae groups were positively associated with FP activity across the entire study population, whilst the Ruminococcaceae family and an unclassified Coriobacteriales family were negatively associated with FP activity. CONCLUSIONS: These data demonstrate significant associations between specific intestinal bacterial groups and fecal protease activity and provide a basis for further causative studies investigating the role of enteric microbes and GI diseases.

Characterization of the fecal microbiota using high-throughput sequencing reveals a stable microbial community during storage.

The handling and treatment of biological samples is critical when characterizing the composition of the intestinal microbiota between different ecological niches or diseases. Specifically, exposure of fecal samples to room temperature or long term storage in deep freezing conditions may alter the composition of the microbiota. Thus, we stored fecal samples at room temperature and monitored the stability of the microbiota over twenty four hours. We also investigated the stability of the microbiota in fecal samples during a six month storage period at -80°C. As the stability of the fecal microbiota may be affected by intestinal disease, we analyzed two healthy controls and two patients with irritable bowel syndrome (IBS). We used high-throughput pyrosequencing of the 16S rRNA gene to characterize the microbiota in fecal samples stored at room temperature or -80°C at six and seven time points, respectively. The composition of microbial communities in IBS patients and healthy controls were determined and compared using the Quantitative Insights Into Microbial Ecology (QIIME) pipeline. The composition of the microbiota in fecal samples stored for different lengths of time at room temperature or -80°C clustered strongly based on the host each sample originated from. Our data demonstrates that fecal samples exposed to room or deep freezing temperatures for up to twenty four hours and six months, respectively, exhibit a microbial composition and diversity that shares more identity with its host of origin than any other sample.
