Pleural EffusionPleurisy1 moreThis is a prospective study to assess the efficacy and safety of a single dose of cefazolin 2g IV for the prophylaxis of surgical site and pleural space infections in patients undergoing medical thoracoscopy.
Point-of-care Ultrasound in Finland
Deep Vein ThrombosisAbdominal Aortic Aneurism8 moreThis study has two aims. Deep venous thrombosis (DVT) is a common suspected medical condition. If it cannot be excluded clinically and using D-dimer, ultrasound examination is required. An option for traditional radiologist-performed ultrasound is a 2-point compression ultrasound (2-CUS). The safety of this technique is proven. However there does not exist any data on costs comparing traditional and 2-CUS pathways in primary health care. This study will evaluate the total cost of both pathways by conducting a cost-minimization analysis. It will also study the effect of a simple ultrasound education on the referrals to hospital due to suspected DVT. Hypothesis 1: Short education in ultrasound will reduce significantly referrals to hospital and save resources. Length of stay (LOS) in emergency department (ED) is related to increased mortality, morbidity, prolonged hospital stay and probably patient satisfaction. LOS of patients with a point-of-care ultrasound (POCUS) performed by an emergency physician (EP) will be compared to those that have a radiology performed ultrasound examination. Further examination and accuracy of POCUS will be noted. Hypothesis 2: POCUS can shorten LOS significantly in selected clinical conditions
Evaluation of a Pocket-Sized Ultrasound Device As an Aid to the Physical Examination
SplenomegalyPleural EffusionThe 40 resident study subjects will be randomized to either receive a training session on use of a pocket-sized ultrasound or to receive training on physical exam skills. Following these sessions the subjects will have the opportunity to practice their skills during clinical rounds at BWH inpatient and outpatient settings. Four weeks after the training session all study subjects will take part in an assessment of their diagnostic skills. During this assessment they will be asked to complete an exam on a patient subject. Those randomized to the ultrasound group will be allowed to use their devices while the control group will use the traditional physical exam. Following the exams, resident study subjects will be asked to indicate whether they detected any of the following abnormalities on their exams: pleural effusion, hepatomegaly, cirrhotic liver, splenomegaly, ascites, aortic stenosis, mitral regurgitation, right atrial pressure, abdominal aortic aneurysm, deep vein thrombosis. Resident study subjects will also complete a questionnaire about the physical exam and use of the ultrasound. Prior to the assessment, all patients will undergo ultrasound by an attending radiologist, and these results will serve as the "gold standard" for our study.

Validity of Pleural Effusion Detection Software
Pleural EffusionThe Chang Gung Pleural Effusion Detection Software is a medical software that can automatically detect whether there is a pleural effusion in Chest X-Ray. The purpose of this study is to verify whether the Chang Gung Pleural Effusion Detection Software can correctly identify patients with pleural effusion in Chest X-Ray. The results of the software analysis will be used for the performance of the software on the primary and secondary outcomes.

Improvement to Perform Thoracocentesis After a Specific Training in Medical Students With the Supervised...
Pleural EffusionFrist Time Indication to Perform a Thoracentesis1 moreMonocentric study, aiming to assess the improvement of medical students to perform a first-time thoracentesis after training using a specific training using an augmented virtual reality simulator, versus standard training. Study population: medical students from the department of Respirology (University hospital of Strasbourg), performing their first thoracocentesis in patients having an indication for a first-time thoracocentesis. This is not an interventional study, no change in patient course being induced because of the study. After the procedure: use of specific surveys for the patient and for medical students to assess the patient's pain, the patient and the medical student level of anxiety, and the student ability during the procedure.
AI Assisted Detection of Chest X-Rays
Pulmonary NodulesSolitary13 moreThis study has been added as a sub study to the Simulation Training for Emergency Department Imaging 2 study (ClinicalTrials.gov ID NCT05427838). The Lunit INSIGHT CXR is a validation study that aims to assess the utility of an Artificial Intelligence-based (AI) chest X-ray (CXR) interpretation tool in assisting the diagnostic accuracy, speed, and confidence of a varied group of healthcare professionals. The study will be conducted using 500 retrospectively collected inpatient and emergency department CXRs from two United Kingdom (UK) hospital trusts. Two fellowship trained thoracic radiologists will independently review all studies to establish the ground truth reference standard. The Lunit INSIGHT CXR tool will be used to analyze each CXR, and its performance will be measured against the expert readers. The study will evaluate the utility of the algorithm in improving reader accuracy and confidence as measured by sensitivity, specificity, positive predictive value, and negative predictive value. The study will measure the performance of the algorithm against ten abnormal findings, including pulmonary nodules/mass, consolidation, pneumothorax, atelectasis, calcification, cardiomegaly, fibrosis, mediastinal widening, pleural effusion, and pneumoperitoneum. The study will involve readers from various clinical professional groups with and without the assistance of Lunit INSIGHT CXR. The study will provide evidence on the impact of AI algorithms in assisting healthcare professionals such as emergency medicine and general medicine physicians who regularly review images in their daily practice.
Clinical Implementation of the Use of Positive Pressure in Chest Drainage
Pleural EffusionBackground: Scientific evidence appoints that the use of non-invasive positive airway pressure in pleural effusion drainage patients is associated with a reduction in these complications, as well as with other benefits. Objectives: To test the implementation of the best evidence-based practices for the use of non-invasive continuous positive airway pressure (CPAP) in patients with chest drainage for pleural effusion, by acceptability, reach, appropriateness, direct costs, feasibility, fidelity, penetration, and sustainability. In addition, to assess the impact of implementing these practices on health-related outcomes of patients having their pleural effusion drained through dwelling time of the chest tube, hospital stay and others relevant outcomes. Methods: quasi-experimental study with pretest-posttest design. Eight hospitals that provide physiotherapeutic care to pleural effusion drainage patients will be involved. The study will be developed in three phases. In phase I, a audit team will help the local research team to elaborate strategies to cope with barriers related to the use of CPAP in patients with pleural effusion and catheter drainage, using a interview with the physical therapist, patient history analysis, and interviews with the patients. In implementation phase, the results obtained from phase I will be presented to physiotherapists to physiotherapists and a discussion will be started on the evidence regarding the best practices in the application of CPAP for educational purposes only. In phase III, new interviews will be held with the physical therapist and patients and the patient histories will be analyzed to assess the impact of the intervention 30 days after implementation phase.
Bleomycin, Doxycycline, or Talc in Treating Patients With Malignant Pleural Effusions
Metastatic CancerRATIONALE: Some drugs such as bleomycin or doxycycline, or other compounds like talc, may help to control fluid in the chest caused by cancer. It is not yet known if bleomycin, doxycycline, or talc is more effective in treating patients with malignant pleural effusions. PURPOSE: Randomized phase III trial to compare the effectiveness of bleomycin, doxycycline, or talc in treating patients with malignant pleural effusions.
