Better Antibiotic Prescribing Through Action Research
Infectious DiseaseThis PAR (participatory action research) study to improve antibiotic prescribing quality in a GPC (general practitioner cooperative) during OOH-care (out-of-hours-care) uses a mixed methods approach using qualitative as well as quantitative techniques. In a first exploratory phase we will work on partnership development and mapping the existing issues. In a second phase the focus will be on facilitating change and implementing interventions through PDSA (plan do study act) cycles. In a third phase outcomes on prescribing quality during and outside office hours will be evaluated. Equally important is the process evaluation and theory building on improving antibiotic prescribing through PAR.
Impact of Dedicated Hygienist Staff on the Occurrence of Intensive Care Unit -Aquired Bloodstream...
Intensive Care Unit -Aquired Bloodstream Infections.The purpose of this study is to evaluate in a multicentric cluster randomized study the effect of the presence of dedicated nurses for training of ICU staff in preventing nosocomial infections. The rate of bloodstream infections per 100 admitted patients is used as the main endpoint. A sample of 4000 included patients in the 6 participating ICU is included with the objective to show a reduction of one third of the rate of ICU-acquired bloodstream infections. The study is currently at the end of the recrutimeent phase.
Comparative Effectiveness of Treatment Options for Genital Herpes Infection to Reduce Adverse Pregnancy...
HSV-2 InfectionPreTerm Birth1 morePreterm delivery (PTD), together with low birthweight (LBW), is the leading cause of infant death and illness, affecting 500,000 births with annual medical costs of more than $26 billion in the U.S. each year. Identifying changeable risk factors to reduce PTD is considered a top research priority. Recent research has shown genital herpes infection (HSV) is associated with increased risks of PTD and LBW. More importantly, treating this infection, including infection with no symptoms, using readily available antiviral medications can be effective in removing the risk due to HSV. Thus, early identification and treatment of HSV in pregnant women could be an effective way to prevent PTD and LBW. Currently, many pregnant women with HSV infection, especially those with no symptoms, choose not to treat due to (a) a lack of demonstrated benefit of treatment and (b) general hesitance to use medications during pregnancy due to safety concerns for the fetus. Thus, emerging evidence of an increased risk of PTD/LBW associated with HSV infection, if untreated, and treatment effectiveness by anti-herpes medications has significantly changed current treatment paradigms among pregnant women. This evidence also provides new hope that effectively treating HSV infection among pregnant women, especially before the 3rd trimester, could lead to a new method to reduce PTD and LBW and reduce racial/ethnic disparities in these risks due to high rates of the infection in minority groups. To further examine the effectiveness of treating HSV in pregnant women to reduce adverse pregnancy outcomes, the investigators propose to conduct a prospective cohort study with a two-stage design combining the large pregnant women population (N=90,000) in Stage I identified through Kaiser Permanente Northern California (KPNC) electronic medical records (EMRs), with a Stage II sample to collect detailed information on additional factors that might muddle our understanding of this issue. This study will address the following: (1) Does treating HSV infection in pregnant women reduce the risk of PTD or LBW? (2) Does timing of the treatment during pregnancy influence treatment effectiveness? (3) Do other factors influence treatment effectiveness? and (4) Does HSV infection in pregnancy, if untreated, increase the risk of PTD and LBW, compared to no infection? Answers to these questions will be valuable to pregnant women and clinicians, and directly address their concerns when making treatment decisions
Advanced Understanding of Staphylococcus Aureus Infections in Europe - Surgical Site Infections...
Staphylococcus AureusSurgical Wound InfectionASPIRE-SSI is a prospective, observational, multicentre cohort study among adult surgical patients, which aims to determine the incidence of healthcare-associated S. aureus infections, particularly S. aureus surgical site infections (SSIs), across Europe and to assess the most important risk factors for this type of infection.
Diagnosing Respiratory Disease in Children Using Cough Sounds
PneumoniaBronchiolitis5 moreThe purpose of this prospective study is to evaluate the efficacy of the ResAppDx software application in diagnosis of pneumonia and other respiratory conditions (bronchiolitis, asthma/reactive airway disease, croup, upper or lower respiratory tract infections) in infants and children. Patient's cough sounds will be recorded using a smartphone and analysed using the ResAppDx software. The ResAppDx diagnosis will be compared to radiologic diagnosis and/or clinical diagnosis. The ResAppDx diagnosis will not be provided to the clinician or patient.

Preventing Surgical Site Infection by Using Prophylactic Occlusive Ionic Silver-containing Dressing...
Surgical Site InfectionBackground: Ionic silver-containing dressing has been proven as a broad spectrum antimicrobial agent to reduce inflammation of wounds and promote healing. However, surgical incisions are usually dressed with conventional gauze dressing in colorectal surgery. Objective: To compare the effectiveness in preventing surgical site infection (SSI) by using conventional gauze dressing and occlusive ionic silver-containing dressing. Methods: This is a single-blind two-arm parallel randomized controlled trial on occlusive ionic silver-containing dressing conducted in Surgery Department of Princess Margaret Hospital. Two hundred patients who undergo emergency or elective abdominal colorectal surgery will be recruited and randomly assigned to have the surgical incisional wound dressed with conventional gauze dressing or occlusive ionic silver-containing dressing. Subjects will be assessed for SSI on day 3, 15 and 30 after operation in a clinical visit followed by phone interviews.
Predicting the Severity of Post-cesarean Wound Infections Using Serum Procalcitonin Levels
Wound InfectionCesarean Wound DisruptionThe serum procalcitonin levels are important during infections and sepsis. The investigators aimed to assess its predictive value in terms of post-cesarean wound infection.
Validation of a Proteomic Signature and Assessment of Viremia in Children With Fever Without Source...
Infectious DiseaseFever1 moreThe study is an observational blinded Validation study in pediatric patients below 3 years old with a diagnosis of Fever Without Source (FWS). In this study the investigators aim to validate the performance of a proteomic signature aiding the physicians to discriminate between viral and bacterial infections in febrile children. The study will also assess the prevalence of Human Enteroviruses (HEV), Human Parechoviruses (HPeV), Adenovirus (AdV) and Human Herpesvirus type 6 (HHV-6) viremia, as well as Kingella Kingae bacteremia in the study cohort.
Impact of Structured Communication in the OR on Surgical Site Infections: Prospective Observational...
Incidence of Surgical Site InfectionShort Intraoperative Briefings2 moreSurgical site infection (SSI) is the most frequent complication in patients that undergo abdominal surgery. A previous prospective observational study in 167 patients undergoing elective open abdominal procedures showed that case-relevant communication protects from organ/space SSI whereas case-irrelevant communication during the last 20 minutes of the procedure is a risk factor for incisional SSI. Therefore, the introduction of a clinical applicable intervention "structured briefing using the StOP protocol" has been developed and was tested in pilot experiments. This intervention aims at improving case-relevant communication during the procedure and to reduce excess case-irrelevant communication at the end of an operation. The hypothesis is: structured briefings during an operation reduce the incidence of SSI after surgery.
