AcademyHealth: Improving

Health & Health Care AcademyHealth is a leading national organization serving the fields of health

services and policy research and the professionals who produce and use

this important work.

Together with our members, we offer programs and services that support the

development and use of rigorous, relevant and timely evidence to:

1. Increase the quality, accessibility and value

of health care,

2. Reduce disparities, and

3. Improve health.

A trusted broker of information, AcademyHealth

brings stakeholders together to address the current

and future needs of an evolving health system,

inform health policy, and translate evidence into action.

The audio and slide presentation will

How to Analyze Survey Data for Free with the R Language

Anthony Damico Statistical Analyst Kaiser Family Foundation

Do you analyze survey data for work or pleasure?

Analyze Survey Data with the scripts on http://asdfree.com

My sincerest apologies Why are you here?

Do you speak any R? Do you analyze survey data

with SAS, SUDAAN, Stata, or SPSS?

Are you concerned that proprietary software makes statistical research

difficult to reproduce?

Does it bother you that your analyses might all be wrong?

Learn R by watching two-minute videos on http://twotorials.com

Do you mind the price tag?

Read the “Getting Started with R” Guide on

Open tutorial

• Data use agreements across institutions o Limited and complicated

o Specific to a particular study

o Resources for sharing are limited

o Security/privacy constraints are hard for small institutions to follow

• Sharing data today o Little incentive

o Only one model: users download data

o Yes/No decision on sharing

Open Data

Thanks Dr. Ohno-Machado for this slide.

Accelerating Open Science

• Research is a Process,

sharing our

experience may

accelerate Science Open Science

Healthcare research

Data collection

Algorithm development

Software implementation

Results verification

Backbone development and verification

UI prototype and soliciting UX advices

Integrated system and leave room for extension

Constantly checking

users’ experience

My Experience in Developing

Grid Logistic Regression

Two stage biomedical webservice

development

Improving users' experience

through involving potential users in

different stages of the development

Motivation

• Traditional approaches to data sharing has

limitations and undermined the ability of

researchers and clinicians to access, aggregate,

and meaningfully analyze patient records at the

point of care.

• WebGlore is a webservice for biomedical

researchers to build a global predictive logistic

regression model without sharing data.

Patient data

Aggregated information, i.e., marginal distribution, sufficient statistics, kernel matrix

Share model vs. Disseminate data

Developers and expertise

Machine learning

Statistics

Signal Processing JAVA, PHP

JSP, PHP

JAVA, PHP

JAVA UI, HTML, CSS

Predictive modeling

Google Code as Version Control

Foundation of GLORE

• Suppose m-1 features are

consistent over k sites

• In each iteration,

intermediary results of a

mxm matrix and a m-

dimensional vector are

transmitted to k-1 sites

Backbone implementation

Implementation • R backbone

o https://www.dropbox.com/s/gmnr

• JAVA backbone o https://code.google.com/p/glore/

Human factor and user experience are important!

Check Point 1：

Performance Validation

Check User Experience

A first thought about UX

Client interface Setup task parameters

Setup task parameters -- filling task details

Client interface Join a task

Client interface Show result

Check Point 2：

Check Potential Users’ Satisfaction

Potential Users’ feedback

• Advantage o Easy to implement

o Flexibility in developing complex interface

o Friendly to tools and packages that sit on local clients

• Disadvantage o Healthcare environments are reluctant to install third party software

o Communication through pre-specified ports is of security concern

o Do not support all platforms unless implemented individually

First webservice development

WebGLORE 1.0

• An easy-to-use software as a service for healthcare

should be: o Plug-in ready(User protected)

o Deployable in a variety of hosting environments (Platform friendly)

o Security and firewall compatible(Security-enhanced network)

Applet-Servlet architecture

Check Point 3：

Check Potential Users’ Satisfaction

Critical advises from testers

• Pros. o Transparent model construction procedures, which allow participants to

see the intermediary steps

o Visualization on model helps users to understand model performance and

reveal important factors

• Cons. o Users cannot see their historical activities

o Users cannot change the user profile

o Repeated warnings from JAVA applet in browsers are annoying

Daniella Meeker, RAND Corporation

Research: Structured Data And Code

Academic healthcare science • Text-based journals are the currency of continued funding

• A journal article eliminates structure and information from original data and puts it into a file cabinet

• Obscuring methods and data

• Slow

dissemination publication

infrastructure

• Methods cannot be exchanged and replicated

• Data is rarely exchanged and re-analyzed for robustness

• Redundant work

• Publication bias

• No infrastructure for efficient collaboration

• Code sharing

• Metadata standards

• No incentives for collaboration in the scientific community

• Journal articles are released slowly and without detail

• Data has greater utility to investigators if it is hoarded

• Academic funding model does not support sustainable infrastructure

Academic healthcare science

Commercial health data science AKA business intelligence

• Environment – the “real” learning health system • Health care practice is moving more quickly than health services

research.

• Post-ACA, providers and plans motivated to leverage their data to find efficiencies

• Despite regulation, healthcare is among the fastest growing segments of cloud computing: infrastructure as a services (IaaS) and software as a services (SaaS)

• Funding model for commercial healthcare data science supports creation of scalable tools and an efficient marketplace for tools and analysis • Software engineers are part of staff

• Analytic services

• Incentives for dissemination are mixed

Collaboration Infrastructure models from other sciences

• Open Science Grid Physics, nanotechnolgy, structural biology

• OSG: 1.4M CPU-hours/day, >90 sites, >3000 users,

• >260 pubs in 2010

• LIGO Physics/Astrophysics

• Established practices and metadata standards

• 1 PB data in last science run, distributed worldwide

• ESGF • 1.2 PB climate data • delivered to 23,000 users; 600+

• Collage – Executable papers Computer science

Incentivizing a Learning Health System

• Research and practice must become interoperable • Requires commitment to a single standard across multiple

agencies • In the age of BI relevant research must go beyond

secondary analysis and link basic biology and biomedicine data with patient reported data

• Repositories and clearinghouses are a good start, but not enough…LHS requires searchable assets with high utility

• discoverable • standards for metadata and coding practices • computable artifacts • application sandboxes with realistically simulated data

• Incentives for collaboration and sharing. • Create a marketplace for reusable tools that links tool

utility and reuse to research funding.

Why Open Source your Data?

From Eric Raymond's “The Cathedral and the Bazaar”

The Tragedy of the Commons

The Magic Cauldron

Prepare to receive the secret recipe for successfully running an Open Source project:

In seriousness

Let your community connect with each other. You need a mailing list

Visit ours at DocGraph.org

Use either

Google Groups

Discourse

DocGraph

Is an graph data set of the healthcare system

It shows how doctors, hospitals, labs, etc work together to provide care

Based on a FOIA request to CMS

~50 Million Edges

~2 Million nodes

Crowdfunded Asked for $15k to develop data set, and got $60k on Medstartr

Open Data set

Download the Open Data Set for $1

Open Source version requires research be contributed back
