LIN, Yihan et al. Cardiac surgery publications in Africa over the last 20 years: A literature review. S. Afr. j. sci. [online]. 2020, vol.116, n.1-2, pp.1-6. ISSN 1996-7489.

There is a significant burden of surgically correctable cardiovascular disease in Africa. The goal of this research was to review the last 20 years of literature on this topic. A systematic search was performed using PubMed, Embase and African Index Medicus for the period 1996-2016. Publications came from 29 countries, all of different income brackets. Research output increased by 15-fold over the 20-year time period, with the majority of publications authored by local teams (71.4%) compared to visiting (4.9%) and mixed teams (23.7%). Although increasing, clinical reporting on cardiac surgery is still limited. Increased publication of results should be encouraged to better benchmark capacity and improve research capacity.SIGNIFICANCE: •The majority of the cardiovascular publications came from local research teams affiliated with public hospitals which suggests strong local engagement in research and cardiovascular care. •Research output significantly increased and the share of literature from major research contributors has relatively shrunk over the study period, which suggests emerging research capacities from previously underrepresented regions. •A demographic analysis of publications showed that studies were set in countries from all income brackets, with the majority of the studies originating from low-income countries. •There is a need to standardise reporting of surgical outcomes which is dependent on perioperative care and maintenance of high-quality health records. •Over half of the publications lacked evidence of outpatient follow-up or data on postoperative care, which highlights the need to focus on patient outcomes as a metric
