I've recently started work on the OpenMRS patient Matching module. Its a complex and intriguing piece of software planned by Dr. Shaun Grannis of the Regenstrief institute.
Dr. Shaun is qualified in both engineering as well as medicine (he's an MIT graduate) and his mathematical training came really helpful in my efforts. I'm also being helped by James Egg, also of the Regenstrief institute. He has been a great help with design planning and domain expertise.
I also found out that Win (Nyoman Ribeka) of OpenMRS had initially got involved in OpenMRS working on the PatientMatching module as a gsoc student ! (this was in 2008)
My work on the module is aimed at calculating mutual information scores for pairwise combinations of columns. This will ultimately make the matching algorithm more efficient.
The work is quite challenging, but intriguing and interesting. I have already made much progress in my work.
for further reference, documentation on the module is available on the wiki here
Credit must also go to Gautami, a fellow Gsoc student who worked on this module during Gsoc 2011.
