"I applied to the Scholars program to follow-up with and increase the scope of the research project that I began working on last summer. I also wanted to have the opportunity to present my work at professional conferences and hope to learn more about the different areas of research taking place at UF aside from medical sciences. My goal is to learn and understand new laboratory and clinical techniques and have a chance to work hard in constructing a scientific paper for publication."

Catheter Hub Contamination: Prevalence and Scrub Duration
Central venous catheter-related (CVC) bloodstream infection is an unusual but potentially deadly occurrence. Each catheter infection caused from such contamination can cost an average of $45,000 in treatment. No national standard exists for proper antiseptic preparation of connector hubs and conclusions are contradictory regarding the scrub duration needed to sterilize the hub. Based on the existing discrepancies, which may result in noncompliance altogether, we intend to determine how to reliably disinfect the hubs through an in vitro investigation. We would like to measure the impact of scrub time on contamination over 1, 2, and 10s. We are also interested in culturing needleless connector hubs in the clinical setting of the operating room (OR) and the intensive care unit (ICU) to determine the prevalence of contamination and additionally, to identify the species of bacteria residing on connectors. Specifically, we are interested in examining two separate categories of hubs: 1) connector hubs from patient CVCs 2) needleless hubs on suspended saline dilution bags in the OR. Past studies have shown an association between bacteria cultured from needleless hubs and stopcocks used to access CVCs and patient bloodstream infection. Connectors would be contaminated either naturally by a finger or by a bacterial suspension. We would subject the site to the above mentioned scrub durations with an alcohol prep pad. Factors such as bacterial transfer (wet or dry) and type (behavior), topological surface complexity, and contaminated surface drying times will be controlled for. Our aim is to determine the time needed to scrub the hubs for successful sterilization. If connector hubs are found to be often contaminated with potentially dangerous bacteria, this data would provide evidence for initiating a program of high vigilance for the standard procedure of sanitizing the ports prior to access on every occasion, helping to ensure patient safety.
