Data blind spots

“Existing literature is clear about the
importance of social determinants of health in improving the health of populations.
These studies uniformly suggest
that nonmedical factors play a substantially larger role than do medical
factors in health.”
https://bluecrossmafoundation.org/sites/default/files/download/publication/Social_Equity_Report_Final.pdf“Leveraging Social Determinants of Health. What Works?” Prepared for the Blue Cross Blue Shield of Massachusetts Foundation by Yale Global Health Leadership Institute.
Understanding why patients opt out of interventions is a blind spot for many organizations.

Much like how a gardener sows his seeds, and cares for and nurtures his garden, managing data, especially at scale, requires
some discipline and, arguably, a good deal of passion.

Semantics Harmonizes Data from Diverse Systems
• Data gathered from diverse sources needs to be stored and reviewed in one consistent form
• Data needs to be “normalized and standardized”
• The data’s content needs to be preserved: its context in time, space and in relationship with other data allowing EMRs to remain viable data sources

Big Data Big Impact
•Access to new, diverse data and open datasets are fueling drug discovery and making clinical trials and research more efficient. Medical research:
•Wearable devices, online diagnostic tools and genetic sequencing services hold the promise of better informed and engaged patients. Daily life:
•Health systems are investing heavily in technology, including machine learning, which is proving as effective as or more effective than human diagnosticians.
The patient experience:
•Telemedicine and health apps make it possible for physicians to see patients virtually, outside of traditional facilities for increased access and tailored care.
Ongoing care:
•Health data is allowing doctors to build better patient profiles and predictive models to more effectively anticipate, diagnose and treat disease.
Prediction and prevention:

•Silos and roadblocks prevent effective data sharing but, at the same time, privacy and security of patient data is paramount.
Data sharing and security:
•Data privacy and interoperability must be addressed at a legislative level to create a regulatory environment that encourages innovation and research while putting patients first.
Policy and legislation:
•Frustrations with the design of electronic medical records undermine the physician-patient relationship.
Electronic medical records (EMRs):
•Without proper infrastructure and a data-literate clinical workforce, health data can only be collected and stored, not leveraged fully.Skills and training:
•Reliance on reactive health care will hamper physicians’ ability to anticipate, diagnose and treat disease. Care models:

• Embrace of digital thus far has been a replacement of analogue
• With Big Data + AI, we should go beyond comparison to humans
• Instead, reinvent what it means to leverage power of machines at scale, and augment most humanistic aspects of care.

Core consideration as Big Data + AI veers towards ‘escape velocity’:
• Data science training• Focus on delivery
mechanisms and workflow, not just apps
• Become more purposeful
• Think more holistically
• Use Big Data + AI to humanize care
