Fifty years of thoracic surgical research in South Africa.
OBJECTIVE
To investigate the scope and trends in clinical research in South African thoracic surgery between 1955 and 2006 and to measure its impact on clinical practice.


METHODS
A systematic review of all SA thoracic surgical publications was performed.


RESULTS
There were 252 general thoracic publications and a marked decrease in publications was noted after the peak period of productivity of the 1980s. There was a shift toward the private sector as an origin of articles and toward a local, non-indexed journal. Inflammatory lung disease was the most frequent topic of publication. Case series and case reports were the most frequent type of article.


CONCLUSIONS
The vulnerability of a small specialty in a developing country is illustrated by the clear trends that emerged. The study provides important indicators for future research, highlights the need for a national database of clinical experience, and emphasises the importance of rekindling interest and a culture of research in thoracic surgery.
