The American College of Chest Physicians (ACCP) in 2001 and British Thoracic Society (BTS) in 1993 and 2003 published guidelines for the treatment of pneumothorax. Here, we review our experience of managing pneumothorax patients, comparing standards of management before and after the publication of the guidelines in 2003. One hundred and twenty patients were transferred to our care for management of pneumothorax between October 2001 and September 2006. One hundred and one patients underwent pleurectomy [28 by video-assisted thoracic surgery (VATS)]. There were 69 males and 32 females with a median age of 47 years (range 15-86 years). 24% (n=24) of patients had evidence of intrapleural infection at time of operation. This was more likely if the time to pleurectomy was >14 days (P=0.03). The median time of referral for patients in the pre-guideline group was 12 days [interquartile range (IQR) 9-12] while post guidelines it was 10 days (IQR 6-13). There was no statistical significance (P=0.09) between these groups in terms of time taken to refer patients. The ACCP and BTS guidelines are not being followed. Pneumothoraces should be managed by chest physicians who are aware of the current guidelines. Impact of delayed referral in the form of increased incidence of morbidity and financial burdens on hospitals needs to be recognized.
