Predictors of morbidity and mortality in secondary spontaneous pneumothorax

Pneumothorax (PNO) is an emergency. Risk factors for morbidity and mortality associated with secondary spontaneous PNO (SSP) are poorly studied. To assess the risk factors for morbidity and mortality of SSP. Retrospective cohort study, including patients with SSP in two public hospitals in Tunisia. Patients were divided into Group 1 (G1): non-operated (N=39) and Group 2 (G2): operated (N=55). There were 94 patients. The risk factors for morbidity for G2 were: partial pneumothorax (p = 0.027), emphysema (p = 0.039) and absence of bronchodilators (p = 0.043). While for G1, it was a history of ipsilateral PNO (p= 0.05). Mortality was noted in G1 more than G2. Factors related to mortality were neoplasia (p = 0.036), and excavation (p = 0.036). For G1, mortality was significantly related to neoplasia (p = 0.037), history of contralateral PNO (p = 0.032), excavations (p = 0.037), current partial PNO (p = 0.027) and intensive care unit stay (p = 0.032). Surgery seems to be the best solution for PSS, with less morbidity and mortality.
