What is Big Data?
https://dzone.com/articles/why-is-big-data-in-buzz

Common Uses of Big Data
9
From Big Data to Better Patient Outcomes
10
Using Big Data for Oral Health Research
• Sources: dental claims, integrated medical and dental claims, practice management software, dental imagery, clinical notes, genetic information.
• Key limitation: Lack of common diagnostic coding or categorization.
• Research with Big Data is NOT like research with survey, exam, or clinical data.
• Not collected with research in mind
• Ill-defined or not defined variables
• Stored in multiple tables, multiple units of analysis
• Requires significant storage and computing power
11
Analytical Strategies with Big Data
1. “Traditional” statistics work, with modified assumptions: 1. Often are population parameters.
2. Measures of variance are either very large or very small.
3. Statistical significance means less, magnitude of effect is more important.
2. Better techniques are those optimized for use in large datasets1. Predictive techniques – Powered regressions, patient similarity, decision
trees, neural networks
2. Probabilistic modeling – Clustering methods, latent class, fuzzy set, association rules
3. Key: The machine learns, but does not interpret or understand.
12
Practical Tools for Analyzing EHR and Big Data
1. Storing Data:
• Languages/Software: SQL, Python, JavaScript, Hadoop,
2. Analyzing Data:1. Non-Distributed Data - R, SAS, Stata
2. Distributed Data – Python, R, Hadoop, JavaScript,
Relational Database
Data Warehouse Data Lake

Big Data Example – Oral Health Over the Lifespan
• Integrated Medical and Claims Data • IBM Watson Medicaid and Commercial in 2017
• Categorization of Dental Claims and Medical Claims for Dental Conditions• Dental Care
– Diagnostics, Imaging, Preventive, Minor Restoration, Major Restoration, Endodontics, Oral Surgery, Periodontics, Prosthodontics, Orthodontics, Anesthesia, Adjunctive General
• Medical Care for Dental Conditions– Dental Care by PCP, Ambulatory Surgery, ED visits, Inpatient Admissions, Oral
Cancer, Rx

Using Big Data to Understand Dental Care in the Primary Care
Setting

Does medical and dental integration improve overall health? Gone are the days of treating dental disease in a vacuum – we now know that by increasing
our focus on prevention and early intervention, we can lower the cost of and
need for medical and dental treatment in the long run - AHIP
The discussion paper focuses on the weak links in the integration process of communication, coordination, and
referral across professions. NAM commentary, 2018
Some private insurers have begun to support this work, reasoning that because the mouth is the
gateway to the rest of the body, oral health impacts the cost of treating other medical
conditions and vice versa. The commonwealth fund, 2015
Medical-Dental Integration for Children
Research Question: What is the relationship between Well Child Visit (WCV) & Preventive Dental Visits (PDV)? Which locations have the most integrated care?
Methods
• Medicaid Data from 2016 and 2017 on Children, Ages 0-20.• WCV in 2016: ICD-10 codes Z00121, Z00129, Z00110-Z00111, Z005,
Z0070-Z0071, Z008, Z020-Z026, Z0282, Z0289; and CPT codes 99381-99385, 99391-99395, 99432 99461.
• Dental Visit during WCV: • Dental Exam: ICD-10 Codes Z0120-Z0121, and CDT codes D0120-D0160. • Dental Diagnoses: ICD-10 codes A690, K000-K149, M260-M279, R6884, R859,
Z463-Z464.
• Visit to a Dentist within 365 Days of WCV• Preventive Dental Visit: CDT Codes D1110-D1999

Summary of Results
• Children were mostly seen at an Office/Hospital for WCV• Including all locations, 2.5% of children received a dental exam and
1.3% received a dental diagnoses at WCV• 63% of children between the 5-9 years who had a WCV visited the
dentist within 365 days• 50% of children who received a dental diagnosis and 45% of children
who received a dental exam visited the dentist within 365 days• Hispanic children are attending preventive visits the most and sooner
out of all children
Future Pathways for Interprofessional Practice
• Understand the reasons why the policies are not transformed into practice?
• Higher efforts for medical-dental integration• Education• CE• Practice

learn before?
Why are there obstacles in using EHRs generated
data?
What are the best sources of big data currently
available?
How is research with big data different from what companies like P & R or
Google are doing?
What is the connection between machine
