Official title: Prospective Study on Clinical Outcomes of Spontaneous Pneumothorax

Status Recruiting

Clinical Trial 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.

Clinical Trial Description

Pneumothorax is a common respiratory disease and potentially recurrent, especially among patients with pre-existing lung diseases. It frequently requires in-patient care due to the need for invasive therapeutic procedures. Pneumothorax can be fatal if treatment is delayed or the pneumothorax is refractory. The in-hospital mortality rate of spontaneous pneumothorax ranges between 0.7% and 15%, which is dependent on age, mode of admission and presence of co-existing lung diseases. 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. A multicentre retrospective study in Hong Kong evaluating patients admitted for pneumothorax in the year 2004 reported a mortality rate of 0.6% in those who had failed drainage with intercostal tube drainage. However, this study was not powered to investigate the overall mortality rate of pneumothorax and its predictive factor. The majority of patients with pneumothorax can be discharged after the resolution of pneumothorax. However, a significant proportion of them may experience prolonged stay in the hospital due to various complications secondary to pneumothorax, including subcutaneous emphysema, persistent air leakage, and hospital-acquired pneumonia. All these conditions may cast negative impact on the overall prognosis, burden of pleural intervention and length of stay. Again, the incidence rate and determining factors of these conditions are seldomly reported. 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. ;
