Abstract
To assist medical professional in better treatment of diseases, and improve patient
outcomes, healthcare has brought about a cognitive computing revolution. The cognitive
computing system processes enormous amounts of data instantly to answer specific queries
and makes customized intelligent recommendations. Cognitive computing in healthcare
links the functioning of human and machines where computers and the human brain truly
overlap to improve human decision-making. In regard to this convergence, this systematic
literature review (SLR) provides comprehensive information of the prior research related
to cognitive computing in healthcare. The SLR focused on methods, algorithms, applications,
results, strengths, and limitation using different research articles collected from
leading international databases using linear and citation chaining search. The main
outcomes of the SLR include proposal on future research direction, challenges faced
by researchers, capabilities and the impact of cognitive computing on healthcare outcome
and a conceptual model, showcasing the better utilization of cognitive computing in
healthcare domain. This study concludes with managerial implications, limitations
and scope for future work.
