Presentation Outline
• The Era of Digital Data
• What can we do with these data?
Improve screening and treatment
Identify high risk patients/groups
Engage patients in healthcare
• What are the strengths and limitations?
What is an EMR?
HOW CAN WE USE THESE DATA?
1. Improve screening and treatment
2. Identify high risk patients/groups
3. Engage patients in healthcare

Use of EMR Improves Clinical Care
• 19% of physicians aware of recommendations, only 3% adhere to all of them (Kologatla & Adams, 2004)
• Barriers include (Rattay et al., 2009):– low self-efficacy,
– inadequate tools/resources,
– lack knowledge/skills,
– lack of time,
– competing priorities,
– insufficient reimbursement, and
– lack of awareness of community resources.
Kolagotla & Adams, Obes Res 2004;12(2):275-83
Rattay et al., Pediatrics 2009;123:S100-7
• In 740k pediatric visits, EMR decision tools (Coleman et al., 2012):
– BMI measurement: 66% to 94%
– Obesity diagnosis: 12% to 61%
– Counseling rates: 1% to 50%
• RCT: Decision alerts, counseling
template, and diagnosis order set:
– Obesity diagnosis: 7% to 22%
– Weight-specific counseling: 15% to 27% (Tang et al., 2012)
• Physician & staff training needed (Coleman et al., 2012)

Use of EMR Improves Clinical Care
Prevent, Identify, Treat Childhood Obesity
• Require BMI assessment; prompt if elevated
• Link to screenings; follow-up visits
• Online database of community resources
• Online counseling
• Monitor patients more frequently

Common Data Model
WHAT ARE THE STRENGTHS AND
LIMITATIONS OF DIGITAL DATA?
Strengths
• Large cohorts of chronic diseases and risk factors
• Cost effective
• Focus on ethnic minority groups and those at/near the poverty line
• Assessments actually conducted in clinical settings
• Can improve clinical diagnosis & treatment
Limitations
• Self-selected appointments
• Physician-selected assessments
• Retrospective data
• Limited validity and reliability
