Impact of Ambulatory Management for Primary Spontaneous Pneumothorax in the Emergency Department on Quality of Life

Официальное название

Impact of Ambulatory Management for Primary Spontaneous Pneumothorax in the Emergency Department on Quality of Life: a Randomized Clinical Trial

Обзор

Outpatient treatment of Primary Spontaneous Pneumothorax (PSP) compared to usual inpatient management could improve quality of care and represent a more efficient, generalizable and sustainable strategy. This multicenter, cluster-controlled, randomized interventional study with stepped wedge implementation will evaluate the impact on quality of life (between inclusion, after drain placement, and 6 months) of an ambulatory strategy for the management of large abundance primary spontaneous pneumothorax in the emergency department, compared with usual care.

Вмешательства

• Другое Ambulatory management
  * Chest tube drainage in emergency department (Furhmann drain connected to Heimlich valve), connected to suction system at -5 to -10 cm H2O until bubbling stops * Follow-up imaging at 4 hours (chest X-ray or low-dose CT scan, depending on management practices in the centers) * if the pneumothorax is still very large, or if clinical tolerance is unsatisfactory (dyspnea, unrelieved pain, abnormal vital parameters), the patient should be admitted to hospital * if the lung is in the process of
• Другое Standard Care
  Hospitalisation in a hospital department (pulmonology, thoracic surgery, short-stay emergency unit, critical care, according to the usual pathway of the center in which the patient is included). In-hospital monitoring until complete resolution of pneumothorax and drain removal (average 4-6 days).
