Active clinical trials for "Dyspnea"

This research work is focused on building and evaluating one of the first evidence-based clinical decision support tools for homecare in the United States. The results of this study have the potential to standardize and individualize nursing decision making using cutting-edge technology and to improve patient outcomes in the homecare setting.

Seismocardiography (SCG) measures the thoracic vibrations caused by the cardiac contraction and ejection of blood into the great vessels. Current smartphones with gyroscopes and accelerometers can measure these vibrations. Based on these components we measure and quantify the cardiac kinetic energy (kinocardiography) in order to differentiate dyspnea of cardiac origin from dyspnea of other origin. The study is conducted in an emergency service where a smartphone performs the measurement during 3 minutes. The results of the kinocardiography-based classification are then compared to the final diagnosis made by a physician. Currently, 235 patients have been included in the clinical study since May 2022. This rapid and non-invasive measurement allows the aid-to-diagnosis of heart failure without being influenced by other factors like the renal function for example that can be NT-pro BNP blood marker.

Dyspnea is a common diagnostic challenge in the Emergency Department (ED). Delay in diagnosis will increase time to correct treatment and could impact outcome. Previous studies have shown excellent diagnostic performance of point of care ultrasound (POCUS) to detect and differentiate between several important diagnosis (e.g heart failure and pneumonia) in patients with dyspnea. However, in most studies POCUS is performed by physicians highly experienced in ultrasound and often studies have focused only on one or few diagnoses. The aim of this study is to compare the diagnostic accuracy of different diagnosis in dyspnoeic patients before and after a ED physician with limited training applies POCUS.

Dyspnea is a frequent reason for referral to emergency departments, leading to a 30-day mortality rate of up to 10% and a 3-month rehospitalization rate of over 30%. Multiple etiologies, as well as poor performance of clinical examination and chest radiography, lead to a diagnostic error rate of nearly 30% at the end of emergency department care. These diagnostic errors lead to rehospitalization and an excess mortality rate of more than 50% compared to patients with a correct initial diagnosis, which is explained in particular by the use of inappropriate therapies. Lung ultrasound is a rapid, non-irradiating, non-invasive, inexpensive, reproducible imaging test that can be used at the bedside. It has a better diagnostic performance than chest radiography, commonly performed in emergency departments.The immediate benefit of lung ultrasound for the most common diagnoses in emergency medicine has already been demonstrated. From an organizational point of view, a few studies have shown a benefit of lung ultrasound in reducing the time spent in emergency departments and the number of additional examinations necessary for the final diagnosis. However, there is no data in the literature on the longer term impact of its use in the emergency department. The primary objective is to evaluate the impact of performing lung ultrasound in terms of 3-month mortality and rehospitalization as part of the diagnostic process for patients admitted to the emergency department with dyspnea.

The aim of this study is to identify correlations between changes from the baseline at Month 24 in Forced Vital Capacity (FVC) (% predicted and mL) and changes from the baseline at Month 24 in cough or dyspnoea scores [points] as measured in the living with pulmonary fibrosis questionnaire (L-PF) over 24 months of nintedanib treatment in patients with connective tissues disease-associated progressive fibrosing interstitial lung disease (CTD associated PF-ILD) under routine clinical practice conditions in Greece.

This is an observational retrospective single-center study (CHRU of Nancy) in patients cared for acute dyspnea by a medical team of the emergencies of the CHRU of Nancy. The main purpose of the study is to evaluate the outcome of patients cared for acute dyspnea by a medical team of emergencies of CHRU of Nancy.

Modern management of acute respiratory failure aims to relieve dyspnea and anxiety by providing a non-invasive respiratory support. This approach tries to avoid endotracheal intubation, patient self inflicted lung injuries (PSILI) and diaphragmatic dysfunction. The present study aims to evaluate dyspnea, pulmonary regional ventilation and diaphragmatic function in patients with hypoxemic acute respiratory failure by different observations, and to bring risk factor for intubation out.

The primary objective of this study is to investigate the correlation between changes from baseline to 52 weeks in Forced Vital Capacity (FVC) [% pred.] and changes from baseline to 52 weeks in dyspnea score [points] or cough score [points] as measured with the living with pulmonary fibrosis (L-PF) questionnaire over 52 weeks of nintedanib treatment in patients suffering from chronic fibrosing Interstitial lung disease (ILD) with a progressive phenotype (excluding idiopathic pulmonary fibrosis (IPF)).
