چکیده

Background. Infectious diarrhea is a common problem in the developing world, especially among people living with HIV/AIDS. Traditional diagnostic methods such as stool culture and microscopic examination is limited by resources. The use of molecular diagnostics for enteropathogen detection in this region of sub-Saharan Africa has not been fully explored. To identify risk factors and characterize enteropathogens from diarrheic stools of HIV positive patients in Gondar, Ethiopia using multiplex molecular panels targeting key infectious agents. Methods. A cross-sectional study of 100 stool samples was performed. Samples were collected consecutively from HIV positive patients presenting with diarrhea at a local clinic in Gondar, a major center in NW Ethiopia. Genomic DNA was extracted from stool and processed in Canada using multiplex molecular panels (Allplex [Seegene Canada] and FilmArray [Biomerieux]). Correlations between patient characteristics, symptoms, public health risk factors and enteropathogen type(s) was explored using STATA (Version 14.1). Results. Ninety-four samples were successfully analyzed by molecular methods. Six samples were excluded due to insufficient volumes. The mean age was 35 with 43% male, 17% living in a rural area, 24% with access only to well water and 74% practicing proper hand hygiene. The majority of patients (68%) were receiving HAART with 32% having CD4 counts greater than 500/μL. Multiple pathogens were detected in 95% of specimens, with 62% having 5 or more enteropathogens. Common bacteria, viruses and parasites detected were Shigella spp./enteroinvasive E. coli (80%), enterotoxigenic E. coli (72%), Norovirus (15%) and C. Parvum (8%). CD4 cell counts and use of HAART were not associated with type or number of enteropathogens detected, though the number of patients with CD4<200/μl was small (23%). Conclusion. Diarrheic stool from HIV-positive outpatients in Gondar, Ethiopia had on average 5 enteropathogens present in their stool. CD4 count was not predictive of pathogen type or number in this study. Shigella spp./enteroinvasive E. coli and enterotoxigenic E. coli are the major pathogens, not dissimilar to immunocompetent individuals in low income countries. Disclosures.

Alerting physicians during electronic order entry effectively reduces unnecessary repeat PCR testing for Clostridium difficile.

Hospital information systems (HIS) alerts restricting repeat Clostridium difficile PCR ordering by physicians in patients with a prior result within 7 days eliminated 91% of repeat tests, from 14.5% (282/1,949) repeats preintervention to 1.3% (135/10,285) postintervention. HIS alerting is an effective, targeted, patient-specific tool for improving the quality and utilization of C. difficile res...

Quality Outcomes in the Surgical Intensive Care Unit after Electronic Health Record Implementation.

BACKGROUND The electronic health record (EHR) is increasingly viewed as a means to provide more coordinated, patient-centered care. Few studies consider the impact of EHRs on quality of care in the intensive care unit (ICU) setting. OBJECTIVES To evaluate key quality measures of a surgical intensive care unit (SICU) following implementation of the Epic EHR system in a tertiary hospital. MET...

Surveillance of Antibiotic Resistance among Hospital- and Community-Acquired Toxigenic Clostridium difficile Isolates over 5-Year Period in Kuwait

Clostridium difficile infection (CDI) is a leading and an important cause of diarrhea in a healthcare setting especially in industrialized countries. Community-associated CDI appears to add to the burden on healthcare setting problems. The aim of the study was to investigate the antimicrobial resistance of healthcare-associated and community-acquired C. difficile infection over 5 years (2008-20...
