heart disease” and “IHD”; as well as clinical records containing all the subtypes
of “Ischemic heart disease” such as “Myocardial Infarction” and “Unstable
angina”.
Context awareness such as negation and pasts events were also applied.
For example, the term “No chest pain”, “No known history of diabetes
mellitus”, and “Symptoms of heart failure” will not be coded as the presenting
condition. Additionally, terms like “Previous history of”, “Previous admission
of”, and “Family history of” within the same sentence as a clinical condition will
not be coded as the current condition for the record.

4. Discussion and Conclusion
When showcasing these abilities to the clinicians, the team agreed that
MyHarmony was able to:
i. Generate more information from free-text utilising the SNOMED CT
structure, thus, reducing the effort needed to collect data in a
structured manner such as in a registry and indicator reports;
ii. Able to generate new information by retrospectively running new
queries on old discharge summary records; thus, reducing the effort
and time to collect data in a prospective manner when new questions
arise, such as for indicator reports that often change on a yearly basis;
iii. Able to deliver information in a timelier fashion; thus clinicians and
health managers are able to plan and take action without waiting for a
1 to 3 yearly report;
iv. Improve documentation of clinicians when they are aware of
MyHarmony’s ability during roadshows.

Generating indicators for monitoring and evaluation can be a burden even
for healthcare facilities equipped with EHR. Conventionally, collecting data for
indicators requires multiple data entries in aggregated manner, with manual
submission to central agencies, where the results are only published on a
yearly basis. Introducing MyHarmony may reduce these burdens. Capturing
data from the source in an automated way, i.e. free text documented by
doctors, would reduce duplication of work and the amount of resources to
capture the data into manual form. Having the data in granular form would
allow a more dynamic analysis and prevents dishonesty. Information required,
whether old or new information, can be formulated and disseminated back to
the clinicians and health managers in a timelier fashion.
MyHarmony has the potential to expand further in its implementation and
technology. However, there are still challenges to be addressed. Currently,
MyHarmony has been developed to mine free-text for Cardiology via a back-
end approach. It uses a single version of SNOMED CT International. The team
is still researching the best approach to manage SNOMED CT versions and its
