A deterioration in the quality of care can be indicated by unanticipated visits for treatment after surgery. The aim of this study was to estimate the percentage of thoracic surgery patients who visit the emergency room within six months of discharge and to identify the causes of those visits. Also noted were the risk factors for postthoracic surgery visits to the emergency room. A multivariate regression analysis was carried out to find possible risk variables for repeat visits to the emergency department.
