Interventions

Patients will be allocated at random (1:1 with random blocks per site) to tube thoracostomy (control group) or non-invasive treatment (intervention group). Both treatments are standard care. Tube thor

Design outcomes

Primary

MeasureTime frame
The primary outcome measure is pneumothorax resolution within 6 weeks after trauma. 

Secondary

MeasureTime frame
The primary outcome measure is pneumothorax resolution within 6 weeks after trauma. Secondary outcome measures are: 1) emergency pleural intervention; 2) Complications; 3) all-cause and pneumothorax or chest trauma-related mortality; 4) pain level at the pneumothorax location during six activities (during maximal inspiration, at rest, at night, and during coughing, daily activities, and self-care) and analgesic drug use; 5) modified Medical Research Council (mMRC) dyspnea scale; 6) hospital length of stay (HLOS) and ICU length of stay (ICU LOS); 7) EQ-5D-5L; 8) (in)direct health care use and work absence including associated costs; 9) incremental cost-utility ratio (ICUR) of non-invasive treatment over tube thoracostomy, expressed as the incremental costs per quality adjusted life years (QALY; based on EQ-5D-5L) gained until 6 months; and 10) incremental cost-effectiveness ratio (ICER) of non-invasive treatment over tube thoracostomy, expressed as the incremental costs per secondary tube placement within 6 weeks.
