Abstract :
Introduction. Management of primary spontaneous pneumothorax (PSP) consists of immediate resolution of pleural air, or
observation, and prevention of recurrence. The risk factors for recurrence remain debated. Objectives. We aimed to describe and
compare the characteristics of patients presenting a first episode of PSP to those of patients presenting a recurrent PSP, in order
to identify factors potentially related to recurrence. Methods. We conducted a cross-sectional study including all admissions for
PSP in the EDs of fourteen French public hospitals from 2009 to 2013. PSP were classified as a first episode if the patient had no
previous history of pneumothorax and as recurrence if a previous episode of spontaneous pneumothorax was documented in the
patient’s medical records or if a recurrence was identified during the inclusion period. To identify factors potentially associated
with recurrence of PSP, multilevel logistic models were fitted. Results. During the study period, 918 (61,6%) first episodes and 573
(38,4%) episodes of recurrent PSP were identified. Clinical presentation, age, gender, smoking habits, and use of cannabis were
similar in both groups. No clinical factor associated with recurrence was identified by multivariate analysis. Conclusion. In this
large multicenter study, no clinical factor associated with recurrence was highlighted.
