* primary focus of healthcare: traditional “one patient at a time” care paradigm,
PopHealth:
Answer to quiz 1: adv: 1) provider might be more likely to participate since they have control over the data. 2) security is simplified. Disadv: 1)have to deal with each EMR; 2) changes in EMR might cause problems.
Answer to quiz 2: Centralized "data lockers". Providers will still have control to the data and queries to respond while keep the data formatting problems to a low level.
Note: PopHealth supports reporting in three different levels
IHIE
Recall that in Lesson 2 we learned process and outcomes measures. The process measure is whether it is done periodically according to guidelines and it’s actual value is a measure of the outcome of care.
Above are examples of provider level HbA1C process metric and QHF outcome metric. State average = red line; regional average = green line.
Here’s a similar report based on HbA1C that shows seven practices are below state average (red line) and five are below their regional average (green line)
Answer to Quiz 4: Mix of patient based on their social, economic or demographic factors.
1) security and trust issues; 2) standardize the clinical data.
Q1: Founding story of Wellcentive, Inc.
A: Two brother in law, one is generating quality measurements using excel sheets, the other is a software engineer who knows how to help with this process both sees a market. They found the company to provide software which helps providers generate quality reports.
Q2. How many data are you collecting and processing?
A: we have about 1000 practices, 8000 physicians are using the service, 25,000 interfaces to collect data from. Process 200 million clinical data points per month. have sent 175 million transactions to payers and resulted in payment based on clinical quality.
Q3. How do you do it?
A: be aggressive on data collection from customer. Create interface to parse, process and interpret the data and put them into structured format so it can be used by the application.
Q4. How do you normalize and standardize data from multiple sources.
A: We do this in a "purpose driven" way: ask customers what should be in the quality report for them to get paid by the payers and only pick out the related data points from the data we get. We then create custom dictionaries of the quality measures and mappings between custom dictionaries to national standards.
Q5. How do you address security issues.
A: HIPPA risk assessment (pass all the checklist) on the application and HIPPA education to employees is required.
Q6. How do the system handle patients who have to see multiple providers?
A: Practice entities are trying to solve the problem internally via DIRECT and HIEs.
Q7. What do you think the role of direct in the complex practice, doctors and patient relationship?
A: We are MU certified so we support standards and protocols such as Direct and CCDA. But we deal with EHR most of the time. We see DIRECT as a technology to get clinical information from outside the practice.
Q8. What we are going in terms of population health can quality measurement.
A: Patient can seek service from multiple places and there data will come from different providers and systems. To access the total quality, one has to gather and aggregate all the data. Base on these, we have to figure out who is responsible for the quality actions and should be paid for the action taken.
FTC ask provider organization only to contract with payers when they are clinically integrated, which is difficult. workflow and health systems need to change their internal structures over time.
Once physician engagement is achieved, then we can see patient engagement.
