IntroductionIatrogenic pneumothorax is a patient safety indicator (PSI) representing a complication of procedures such as transthoracic needle aspiration, subclavicular needle stick, thoracentesis, transbronchial biopsy, pleural biopsy, and positive pressure ventilation. This study examined whether there was a significant difference in rate of iatrogenic pneumothorax in teaching hospitals compared to non-teaching hospitals from 2000 to 2012.Materials And MethodsWe performed a retrospective cohort study on iatrogenic pneumothorax incidence from 2000 to 2012 using the Healthcare Cost and Utilization Project (HCUP) database. Pairwise t tests were performed. Odds ratios and P values were calculated, using a Bonferroni-adjusted α threshold, to examine differences in iatrogenic pneumothorax incidence in teaching vs. non-teaching hospitals.ResultsOur study revealed that after the year 2000, teaching hospitals had significantly greater iatrogenic pneumothorax incidence compared to non-teaching hospitals in every year of the study period (P<.001).DiscussionIatrogenic pneumothorax occurred with significantly greater incidence in teaching hospitals compared to non-teaching hospitals from 2000 to 2012. This trend may have been enhanced by the residency duty-hour regulations implemented in 2003 in teaching institutions, or due to higher rates of procedures in teaching institutions due to the nature of a tertiary center.ConclusionsIatrogenic pneumothorax was more prevalent in teaching hospitals compared to non-teaching hospitals after the year 2000. Further randomized control studies are warranted to evaluate the etiology of this finding.Published by Elsevier Inc.
