NCT06921993
Pneumonia is a major cause of illness and death in children, with an annual incidence of about 3.3 per 1,000 in those under five years old, many requiring hospitalization. The diagnosis is challenging due to the absence of a universally accepted gold standard, leading to variability in emergency settings. Current guidelines recommend diagnosis based on history and physical examination, which do not reliably differentiate pneumonia from other respiratory infections or identify whether it is bacterial or viral in nature. This uncertainty can lead to the unnecessary use of antibiotics. Commonly used chest X-rays have limitations such as low sensitivity, moderate interobserver reliability, and the inability to distinguish bacterial from viral pneumonia. In contrast, lung ultrasound has shown high sensitivity and specificity for diagnosing pneumonia in children. However, lung ultrasound also cannot reliably distinguish between bacterial and viral causes and might lead to increased antibiotic prescriptions by detecting minor lung consolidations not seen on chest X-rays. Despite these issues, lung ultrasound is widely used in pediatric pulmonary assessment. The primary objective of the study is to determine if using lung ultrasound for diagnosing pneumonia in children can reduce antibiotic prescriptions compared to the standard care approach-which mainly relies on clinical diagnosis (often supplemented by chest X-ray and blood tests in selected cases). The secondary objective is to assess how frequently lung ultrasound impacts management decisions during a single clinical visit, beyond the information provided by history and physical examination. The third objective is to compare the diagnostic accuracy of lung ultrasound-supported diagnosis with existing diagnostic methods. The study hypothesizes that lung ultrasound results can act as a decision modifier, similar to other clinical tools and examination findings. However, a lack of consensus on specific lung ultrasound parameters and their clinical correlations contributes to variability in managing suspected pneumonia, potentially leading to antibiotic overuse. Eligible participants are children aged three to ten years who are in good general condition and clinically stable, presenting with signs and symptoms of lower respiratory tract infection indicative of pneumonia. Exclusion criteria include children outside the specified age range, those recently hospitalized, those who have undergone prior chest imaging, those already on antibiotic therapy, those with severe clinical instability, and those with underlying conditions predisposing them to severe or recurrent pneumonia. These criteria help ensure that the study population represents general pediatric community-acquired pneumonia cases, avoiding biases from high-risk patients. The ultimate goal of this study is to provide evidence on whether lung ultrasound can serve as a reliable tool to guide antibiotic prescriptions, thereby reducing unnecessary antibiotic use in the management of pediatric pneumonia.
NCT06106204
The goal of this two-arm parallel cluster-randomized trial of 40 hospitals is to test the effectiveness of the ROAD Home Intervention on days of antibiotic overuse at discharge in patients hospitalized with community-acquired pneumonia (CAP) or urinary tract infection (UTI). The main question it aims to answer is: Does an antibiotic stewardship approach that is customized to the needs, goals, and resources of a hospital (i.e., the ROAD Home Intervention) compared to standard stewardship approaches reduce antibiotic overuse at discharge in hospitalized patients with CAP and UTI? The investigators will randomize 20 hospitals in the Michigan Hospital Medicine Safety Consortium (HMS) to the intervention group and 20 HMS hospitals to the "usual care" control group. During the study the investigators will: (a) assess baseline performance, existing stewardship strategies, hospital priorities, and resources; (b) develop a customized discharge stewardship "suite" for each intervention hospital based on the findings of the baseline assessment and informed by the ROAD Home Framework; and (c) support hospitals in selecting strategies and creating an implementation blueprint to be implemented over 12 to 15 months. After the intervention period, the investigators will compare days of antibiotic overuse at discharge and patient outcomes between intervention and "usual care" hospitals. It is hypothesized that hospitals randomized to the ROAD Home Intervention will have fewer days of antibiotic overuse at discharge compared to "stewardship as usual" control hospitals.
NCT06772675
This multi-center, cluster randomized study aimed at improving implementation of vancomycin reducing practices (VRP) in neonatal intensive care units (NICUs). Sites will be recruited and randomized to receive either external facilitation or no external facilitation to assess the effect on center-level fidelity to the core components of VRP implementation. Interventions available to both study arms are directed at hospital staff and includes identification of local champions, educational outreach, unit-level audit \& feedback, and use of a clinical decision support tool.
NCT07267624
The objective of the study is to determine whether rapid multiplex PCR testing of respiratory samples can reduce exposure to broad-spectrum antibiotics in intensive care unit patients with suspected or confirmed ventilator-associated pneumonia, compared to standard diagnostic methods. As secondary objectives, the investigators will study antibiotic management and overall antibiotic consumption, as well as escalation or de-escalation events. The investigators will study the potential clinical impact of using multiplex PCR to see if the length of stay in the intensive care unit is reduced, as well as the duration of mechanical ventilation.
NCT06977971
This study retrospectively evaluated the clinical, laboratory, and radiologic factors that influence the decision to prescribe antibiotics in children under 2 years of age hospitalized with RSV-positive acute lower respiratory tract infections. The study also examined the economic impact of antibiotic use in these patients. The goal is to improve clinical decision-making and reduce unnecessary antibiotic exposure in children with viral infections.
NCT06278896
This is a randomized, open label clinical trial among individuals with hematologic conditions. The trial aims to evaluate the safety and clinical outcomes of de-escalating antibiotic therapy among stable individuals diagnosed with neutropenic fever, in which no bacterial infection has been identified.
NCT04453540
The research aims to determine the impact of a syndromic mutiplex PCR assay (FilmArray) on the management of patients hospitalized in ICU for severe respiratory disease. During the SARS-CoV-2 outbreak, the diagnosis of pneumonia has become considerably more complex as the biological, radiological and clinical criteria of covid-19 interfere with the standard criteria for the diagnosis of severe respiratory diseases. Moreover, patients with COVID-19 are at higher risk of developing other associated infections and thus, patients have therefore often been treated with antibiotics, adequately or not, due to difficulty to quickly identify the etiology of their symptoms with conventional methods. In order to improve their treatment, both diagnostic and therapeutic, we set up a new syndromic molecular test in our laboratories to accelerate and improve the pneumonia management and antibiotic stewardship. This research will include 100 to 150 adult patients hospitalized in ICU during the first half of 2020. It will take place within the Nancy University Hospital and the Reims University Hospital, France.
NCT03245879
Core elements of effective antibiotic stewardship programs (ASPs) have been identified and evidence-based guidelines have been developed for implementation. The majority of the evidence used for these guidelines are from published studies on the effectiveness of ASPs in large academic or large community hospitals. A significant portion of healthcare in the United States, however, takes place in small hospitals. In 2015, 73% of US hospitals had \< 200 beds (4,057 hospitals) and accounted for 29% of all US inpatient bed days. Limited studies on the effectiveness of antibiotic stewardship implementation have been performed in hospitals with \< 200 beds. Antibiotic use rates and selection patterns in these small hospitals are similar to that of large hospitals and the majority of small hospitals lack formal ASP that meet the CDC's core elements. The objective of this real-world implementation study was to assess the effectiveness of three ASP strategies of escalating intensity designed specifically for small hospitals within a vertically integrated healthcare delivery system.
