Prospective Study on Clinical Outcomes of Spontaneous Pneumothorax
Trial Parameters
Brief Summary
Pneumothorax can be fatal if treatment is delayed or the pneumothorax is refractory. However, the mortality rates and their risk factors were mainly reported from retrospective studies, and local data regarding the mortality of spontaneous pneumothorax is scarce. This study aims at evaluating the in-hospital mortality and relevant clinical outcomes of spontaneous pneumothorax and identifying their predictive factors. The data collected from this study will also guide the planning of subsequent research to overcome the knowledge and service gap in managing spontaneous pneumothorax.
