To determine the effectiveness of an enhanced strategy for daily disinfection in acute care hospital rooms comparing the addition of sani24 to routine daily cleaning versus the control of routine daily cleaning.
The purpose of this study is to understand the effect that 3 different types of root canal procedures have on bacteria.
The purpose of this study is to develop a protocol for biofilms disinfection with a FDA cleared, clinically approved and commercially available Er,Cr:YSGG laser treatments. This protocol will be testing local single topical application of Lasers within the canal system in patients going through routine endodontic treatment, evaluate its potential as anti-biofilm treatment and compare it to other currently used antibacterial protocols.
Appalachian Kentuckians in Martin and Letcher Counties are grappling with a health-threatening drinking water crisis arising from exposures to disinfection by-products (DBPs). DBPs include trihalomethanes (THMs), haloacetic acids (HAAs), chlorate, and other compounds that have been associated with a variety of adverse health effects, including increased risk of bladder cancer and cardiovascular birth defects. This study implements a multi-stakeholder, multi-method approach to improve understanding of, characterize spatial and temporal variations in, and reduce exposure to DBPs in these Appalachian Kentucky counties.
Antibiotics are commonly utilized to reduce the bacterial population of the eye prior to surgery with the assumption that this reduces the risk of endophthalmitis, although it is not clear if this actually occurs. This study will investigate the use of Hypochlorous Acid, a commercially available over the counter (OTC) medication to see if this will reduce the bacterial population prior the cataract surgery.
The purpose of this study is to understand and learn better the efficacy of GentleWave and obtain histological evidence of the efficacy of this new technology done in-vivo
To compare the efficacy and comfort of two FDA approved pre-injection antiseptics when used for intravitreal injections.
Insertion and maintenance of central venous catheter (CVC) lines are common hospital procedures in patients, including those being treated for cancer. CVCs allow clinicians an access point for infusion of fluids, blood sampling, and measurements, decreasing the need for repeated needle sticks to the patient. However, bloodstream infections associated with CVCs (CLABSIs) are a serious complication, leading to significantly longer hospital stays, morbidity, and mortality. Keeping catheter ports disinfected reduces the risk of bloodstream infection; however, consistent and adequate maintenance and disinfection of the line can be difficult. The purpose of this study is to demonstrate that passive disinfecting caps can provide a patient safety practice that is easy for clinicians to follow, as well as providing easily auditable compliance, which may lead to lower CLABSI rates. The compliance rate for needleless connector disinfection will be evaluated after implementation of the passive disinfecting cap, and compared to the pre-intervention rate. The CLABSI rates before and after cap implementation will also be compared.
The objective is to conduct a prospective, sham controlled, double-blinded, interventional crossover trial to compare standard terminal cleaning plus PX-UV (intervention) with standard terminal cleaning plus sham PX-UV (control) with crossover at 12 months, following a 6-month washout period. Outcome measures include the rates of HAIs, as well as the recurrence of genetically identical clinical strains of HAIs among patients on study units. The study will be conducted in 2 hospitals covering 16 total hospital units at Detroit Medical Center. Our central hypothesis is that the addition of PX-UV to standard terminal cleaning will be associated with a significant reduction in the rate of HAIs, as well as a reduction in the recovery of genetically identical strains of MDROs. The impact of PX-UV disinfection on rates of HAIs on study units will be determined by comparing rates of HAIs on a) study units where PX-UV is added to standard terminal cleaning practices to b) units where a sham UV disinfection system is added to standard terminal cleaning; and by comparing rates of HAIs on the same medical ward during each of two 12-month phases of a crossover study (one phase when a PX-UV device is added and one when a sham device is added to standard terminal cleaning). The long-term goal of this project is to establish the efficacy of terminal cleaning plus PX-UV in reducing rates of HAIs due to the following multi-drug resistant organisms (MDROs): C. difficile, vancomycin-resistant enterococci (VRE), Klebsiella pneumoniae and Escherichia coli producing extended-spectrum beta-lactamases (ESBLs), methicillin-resistant Staphylococcus aureus (MRSA) and Acinetobacter baumannii. At the conclusion of the proposed project, novel data will be generated from this rigorously controlled study regarding the effectiveness of PX-UV in reducing HAIs in a representative, real-world healthcare setting.
Enhanced terminal room disinfection is a novel, promising, but still unproven strategy for the prevention of healthcare-associated infections (HAIs) due to selected multidrug-resistant (MDR) bacterial pathogens. The investigators will perform a large prospective, multicenter study enhanced terminal room disinfection to 1) determine the efficacy and feasibility of enhanced terminal room disinfection strategies to prevent HAIs and 2) determine the impact of environmental contamination on acquisition of MDR-pathogens among hospitalized patients.
The objective of the trial is to assess the impact of a disinfection and hand hygiene program on absenteeism in elementary school classrooms. Students in intervention classrooms will use alcohol-based hand sanitizers at school, and their classrooms will be disinfected using quaternary ammonium wipes. We hypothesize that the use of disinfectants and hand hygiene products in elementary school classrooms will reduce absenteeism.
This study will examine whether genetic differences among individuals affect blood levels of certain chemicals called DBPs after showering. Chemicals such as chlorine and ozone are used to kill germs in water. These chemicals may react with organic matter in the water and form other chemicals called disinfection byproducts, or DBPs. Although people are usually exposed to DBPs by drinking tap water, these chemicals may also penetrate the body during showering. This study will see whether the levels of DBPs after showering vary among individuals depending on differences in genes that code for enzymes called GSTT1, CYP2D6, and CYP2E1, which break down DBPs. This study, sponsored by the Centers for Disease Control and Prevention and the National Institutes of Health, is conducted at the University of Pittsburgh's Center for Clinical Pharmacology. Healthy adults between 18 and 45 years of age who do not smoke cigarettes and are not taking any medicines may be eligible for this study. Candidates are screened with a medical history and blood and urine tests. Participants are given a diary to record the foods they eat and how much water they drink during the 2 days before their study appointment. The following activities are scheduled on the appointment day: * Measurements of blood pressure, height, and weight, and pregnancy test for women * Questions about alcohol consumed and medications taken in the last 48 hours * Review of food and water diary * Interview for demographic information (name, address, date of birth, etc.) and other information, such as sex, height, weight. Subjects are also asked about anything, such as exercise, that might affect their breathing, since breathing problems are a rare side effect of chlorzoxazone, a drug used in this study. * Urine sample collection * Blood draw and insertion of a small catheter (plastic tube) to allow for additional blood draws during the test procedure without having repeated needle sticks * 10-minute shower in a private bathroom * Blood sample collection 10 minutes after the shower and again at 30 minutes after the shower * Dose of chlorzoxazone (a drug used to treat muscle pain) * Interview about subject's exposure to water * Light breakfast * Blood and urine collections 2 hours after the chlorzoxazone dose * Lunch * Observation for drug side effects for 2 hours, or longer if needed Seven blood samples totaling 75 milliliters (about 5 tablespoonfuls) of blood are collected during this study. The blood is tested for chemicals called trihalomethanes to see how they are broken down. The urine samples are tested for chemicals called haloacetic acids, which are found in tap water after it has been treated with chlorine.
This exploratory cross sectional cohort study will evaluate the feasibility and fidelity of using an innovative strategy, the Patient Motivational Dialogue (PMD)/PMDPlus that will intentionally motivate and encourage the patient toward self-advocacy for their Health Care Professional's (HCP's) hand hygeine (HH) adherence.
The purposes of this study are to identify the common bacterial flora on the hand and evaluate the efficacy of readily available skin-preparation solutions in the elimination of bacterial pathogens from the surgical site following skin preparation. The null hypothesis is that there is no difference in the efficacy of Chloraprep, Duraprep, and betadine in pre-operative skin preparation in clean, elective hand surgery cases.
This is a Phase 3 multi-center, group-randomized, crossover trial to compare nasal antimicrobial photodisinfection therapy (aPDT) with standard of care for prevention of surgical site infections in patients undergoing major elective, urgent, or emergent surgeries in a hospital setting. The main outcomes are to: 1. compare the efficacy, and 2. estimate the safety of applying nasal (aPDT) before surgery in reducing the incidence of SSIs within the initial 30 days after surgery compared to standard of care (SOC). Participants in the intervention group will receive aPDT prior to surgery on the day of surgery. Participants in the control group will receive standard of care surgical site prevention measures prior to surgery.
The goal of this observational is study is to develop a protocol for root canal biofilms disinfection using a clinically approved and commercially available iron oxide nanoparticle formulation Ferumoxytol/H2O2 treatments. This protocol will be testing local single topical application of Ferumoxytol within the root canal system in patients going through routine root canal treatment, evaluate its potential as anti-biofilm treatment and compare it to the clinical gold standard disinfecting solution sodium hypochlorite (positive control) and saline (negative control).
Microorganisms that colonize hospital environments play an important role in the transmission of hospital acquired infections (HAI) and multi-drug resistant organisms. Previous studies examining microorganisms in the hospital environment have been limited by reliance on targeted culture-based methods resulting in potentially missed or unrecognized organisms. Evidence now suggests that using microbiome analysis offers an innovative strategy that may improve our understanding of HAI and how best to prevent them. This pilot longitudinal observational study aims to characterize the taxonomic composition of microbial communities on environmental surfaces and people in these environments prior to and following the introduction of patients, caregiver, and hospital staff to newly constructed inpatient care areas at St. Jude Children's Research Hospital (SJCRH). This proposed study is uniquely characterized by evaluating the hospital environment of a pediatric immunocompromised oncology patient population that has not been studied in the past using advanced molecular techniques such as microbiome analysis. PRIMARY OBJECTIVE: * To describe the pattern of microbial communities of the hospital environment before, during and after patient occupancy of a newly constructed hospital space. SECONDARY OBJECTIVES: * To describe the similarity or difference of environment microbial communities to that of the humans occupying this environment in a newly occupied hospital space. * To describe the pattern in environment microbial communities after each step of disinfection (manual cleaning with chemical disinfectant and Ultraviolet light disinfection machine) after patient discharge from the inpatient hospital environment. * To evaluate the correlation between environmental Adenosine Triphosphate (ATP) measures and organism bioburden.
The purpose of this study to determine whether Aquatabs, a water treatment tablet, reduces diarrheal diseases in a peri-urban population of Tamale, Ghana.
The CLEAN (ChLorine to reduce Enteric and Antibiotic resistant infections in Neonates) cluster randomized controlled trial in western Kenya will evaluate the impact of a multi-component chlorination intervention in health care facilities on maternal and neonatal health. Intervention facilities will receive a passive chlorination technology for water supply treatment and a reliable supply of sodium hypochlorite disinfectant. Both intervention and treatment facilities will receive infection prevention and control messaging. The goal of the study is to evaluate the impact of the intervention on bacterial contamination of water supply, on staff hands, and on high-touch surfaces in maternity wards, and the following outcomes among facility-born neonates and their mothers: (1) gut carriage of bacterial pathogens associated with sepsis one week post-birth, (2) gut carriage of antibiotic resistant bacteria one week post-birth, and (3) symptoms of possible serious bacterial infection one week following birth.
Approximately 40 million people in the US are served by private, and frequently untreated, wells. Our best estimate is that 1.3 million cases of gastrointestinal illnesses (GI) per year are attributed to consuming water from untreated private wells in the US, but in reality, there are no robust epidemiological data that can be used to estimate cases of GI attributable to these sources. We propose the first randomized controlled trial (RCT) to estimate the burden of GI associated with private well water. We will test if household treatment of private well water by ultraviolet light (UV) vs. sham (inactive UV device) decreases the incidence of GI in children under 5. We will also examine the presence of viral, bacterial, and protozoan pathogens in stool and well water from participants. These data will fill a knowledge gap on sporadic GI associated with federally-unregulated private water supplies in the US.
