HEALTH INFORMATICS
Health informatics had been loosely practiced in
the Philippines as early as the 1980s.
Practitioners who had access to IBM compatible
machines were already using word processors to
store patient information by then. Since then,
significant milestones in health informatics have
also occurred over the years, one of which is the
Community Health Information Tracking System
(CHITS), a Linux, Apache, MySQL, PHP-based
system released under the general public license
(GPL).
Health Informatics in the Philippines – Despite
the developments in health informatics in the
Philippines, the nation still suffers from various
issues that hamper its progress:
o Lack of human resource interest in the field.
o Benefits of information technology do not
seem apparent to many decision-makers in
the healthcare sector.
o Large initial expenditure for a health
information system remains another barrier
to the integration
HEALTH INFORMATION TECHNOLOGY
“The area of IT involving the design, development,
creation, use, and maintenance of information
systems for the healthcare industry.” – Rouse (2016)
Automated and interoperable healthcare
information systems are expected to:
1. Improve medical care
2. Lower costs
3. Increase efficiency
4. Reduce error
5. Improve patient satisfaction
HEALTHCARE SOFTWARE SYSTEMS
Electronic Health Record (EHR)
• Central component of the health IT
infrastructure.
• Electronic medical record
•
A person's official, digital health record and is
shared among multiple healthcare providers
and agencies
Personal Health Record (PHR)
• A person's self-maintained health record, and
the health information exchange (HIE)
Health Data Clearinghouse
• A group of healthcare organizations that enter
into an interoperability pact and agree to
share data between their various health IT
systems.
Picture archiving and communication systems (PACs)
• Imaging technology
Vendor neutral archives (VNAs)
• Store and manage patients' medical images. In
the past, radiology departments have been
the primary repositories of medical images,
but PACS and VNAs are integrating radiology
into the main hospital workflow, and other
specialties such as cardiology and neurology
have also become large-scale producers of
clinical images.
HEALTH INFORMATION ECOSYSTEM
Health Interoperability Ecosystem
• Composed of individuals, systems and
processes that want to share, exchange, and
access all forms of health information,
including discrete, narrative and multimedia.
• Each potential stakeholder is involved in the
creation, exchange and use of health
information and/or data.
• Provides an information infrastructure that
uses technical standards, policies and
protocols to enable seamless and secure
capture, discovery, exchange and utilization of
health information

HEALTH INFORMATICS IN THE CLOUD
•
•
83% of healthcare organizations are making
use of cloud-based applications, and it is
changing the landscape of the healthcare
system and health informatics.
“Cloud computing” is a method for delivering
IT services in which resources are retrieved
from the Internet through web-based tools
and applications.
2. Cloud Set-up Seems Cumbersome
• The transition from a traditional to an
automated system might be difficult to some
members of healthcare
• organizations, particularly for smaller or older
practices that may not be familiar with cloud
technology.
CHITS
Community Health Information Tracking System
ADVANTAGES:
1. Integrated and Efficient Patient Care
• Cloud technology offers a single access point
for patient information, and this allows
multiple doctors to review lab results or notes
on patients.
• Physicians can spend more time deciding and
performing patient treatment instead of
waiting for information he needs coming from
different departments.
2. Better Management of Data
• The accumulation of electronic health records
will allow more meaningful data mining that
can better assess the health of the general
public.
• More data can mean more opportunities to
identify trends in diseases and crises.
DISADVANTAGES:
•
•
•
CHITS was named finalist at the Stockholm
Challenge 2006 and one of top three egovernment projects in the Philippines by the
Asia Pacific Economic Cooperation Digital
Opportunity Center.
CHITS is an electronic medical record (EMR)
developed through the collaboration of the
Information and Communication Technology
community and health workers, primarily
designed for use in Philippine health centers
in disadvantaged areas.
It is currently utilized in 111 government
health facilities. What used to be manually
done before, taking up 4 to 5 minutes, can
now be executed within a couple of seconds.
The implementation of CHITS has indeed
resulted to heightened efficiency among
health workers, since more time can be spent
on providing patient care (Department of
Science and Technology, 2012).
1. Potential Risks to Personal Information
• The information contained within medical
records may be subjected to theft or other
violations of privacy and confidentiality.
Fortunately, safeguards may be put in place in
order to minimize such threats, such as
encryption, proper data disposal, and other
security features.
