Making best use of existing dataData + analysis + visualisation

Big data – opportunities in health dataLinkage, care.data

Big data – other data setsPollution, NHS choices, lung age, apps etc

4 VsVolume, variation, velocity, veracity

Data quality is a big issue BUT insight possible, feedback necessary, incentives to improve needed

What is data science?

Content

• There is lots of information out there• Huge variation in service• What data science will bring next

What is available now: 1

Information on mortality from respiratory disease:• ONS recently published a large dataset on deaths by cause since 2000:• This is visualised here https://public.tableau.com/profile/musicwallaby31#!/

vizhome/Deaths_century/Dashboard6 • Total deaths from respiratory disease are static =>Rates are decliningAsthma deaths are decreasing

Practice profiling• (Yes we know it’s a lot of QOF) but…for example, practices which

assess OPCD patients better also assess asthma patients better

What is available now: 2

We created INHALE to try and pull together population based publicly available information about COPD and asthma into a single site:http://fingertips.phe.org.uk/profile/inhale

INHALE went some way to pulling together population based publicly available information about COPD and asthma into a single site:http://fingertips.phe.org.uk/profile/inhale

Information on population activity: Standardised rate of emergency admissions for COPD, by CCG

What is available now: 2

What is available now: 3

Information on provider processes: Emergency re-admission rate at 30 days for patients admitted in an emergency for COPD

Source: Methods Stethoscope

There is huge variation: 1

Variation: In hospital crude mortality rate following admission for COPD

National range 8.4 to 71.7 deaths per 1,000 admissions Over 8 fold variation

So let’s follow that one and look at the top outlier.

See the 3 year trend!

The future

• Patient specific• Personalised predictive risk of exacerbation alert on your phone?

• Public health• Crowd source data to understand variation in population lung age and

understand factors causing this variation
