Dyspnea is a common chief complaint leading to emergency department (ED) visits. Multiple conditions may cause or be associated with dyspnoea, including bacterial pneumonia, acute heart failure (AHF), exacerbation of chronic obstructive pulmonary disease (COPD) or asthma and pulmonary embolism. Each of these diagnoses has a specific treatment recommended by international guidelines. Inappropriate treatment in the ED is more frequent among elderly patients and is independently associated with in-hospital mortality. Point-of-care ultrasound is immediately available at the bedside. Lung and cardiac ultrasound (LuCUS) offers excellent diagnostic accuracy for bacterial pneumonia, AHF and COPD exacerbations, even in elderly patients. The primary objective of the LUC REED trial is to evaluate the impact of a LuCUS-guided strategy versus standard care on reducing inappropriate treatment of dyspnoea in elderly ED patients.
The LUC REED trial is a prospective, interventional, multicentre, stepped-wedge randomised controlled trial designed to assess the superiority of a LuCUS-guided strategy over standard care in ensuring treatment appropriateness for dyspnoea in elderly ED patients. The study will include 504 patients over 2 years. Patients aged >65 years presenting with acute dyspnoea and signs of severity (respiratory rate ≥22 or SpO2

To determine whether postponing daily medical rounds to provide additional preparation time for residents reduces round duration and alters time allocation during rounds, with the hypothesis that increased preparation leads to more efficient rounds without reducing patient contact.
Time and motion study with a before-and-after comparison.
Internal medicine division of Lausanne University Hospital, a Swiss tertiary teaching hospital.
75 residents; 60% women; mean age of 29.6 years and 3.0 years of training.
In 2017, the daily work schedule was reorganised by postponing rounds from 09:00 to 10:00 and moving educational sessions to the afternoon, thereby freeing 90 min to prepare patient cases before rounds.
The primary outcome was the duration of rounds and the proportion thereof spent with patients, using computer systems or in discussion with colleagues. Secondary outcomes included the detailed distribution of resident activities during the officially scheduled round period, particularly time dedicated to supervision, teaching and administrative tasks.
Round duration decreased from 142 min per shift (95% CI 128 to 156) in 2015 to 112 min (95% CI 101 to 124) in 2018 (p=0.001). The proportion of round time spent directly with patients remained stable at 47%. Computer use during rounds decreased from 43% to 32% (p
Postponing rounds to allow more preparation time was associated with shorter, possibly more efficient rounds, reduced computer use in patient presence and increased supervision and teaching.
