NoteThree random comments from previous attendees
- I think this was a really good session. I do think there will be learning for people in the coding of part similarly to excel. I do think it was good to know that it looks like excel but is not.
- Wonderful introduction into future of data analysis.
- Good journey describing how to obtain data and map accordingly with various visuals.
Why this session?
- Power BI is genuinely useful for health and care work
- but (like always) that recommendation comes with quibbles and qualifiers
- this session = non-technical, unvarnished advice about what Power BI does, where it shines, how it might help your service, and ways of putting it into action

Power BI?
- tool to build interactive dashboards
- newish (c.2015), proprietary, paid-for
- integrates functions from several Microsoft data products (bits of Excel, PowerPivot, PowerQuery…, SQL reporting products)
- a terminal analysis product: designed to make dashboards that users can use, rather that wrangle data/do statistical analysis
Power BI demo
We’ll use a pair of Excel files. These are based on three datasets from the Scottish Health and Social Care Open Data portal:
- GP practice size data - which is based on the GP practice details dataset and the Health Board 2014 - 2019 dataset
- Demographic data - which is based on the GP practice populations dataset
| Name | PracticeListSize | Postcode | HBName | GPCluster | Code |
|---|---|---|---|---|---|
| Broughty Family Healthcare | 9204 | DD5 1EP | NHS Tayside | Dundee 2 | 11306 |
| Dr Ferguson & Partners | 10666 | G41 1HU | NHS Greater Glasgow and Clyde | S - Pink | 52128 |
| Drs Datta & Partners | 4914 | G52 3SS | NHS Greater Glasgow and Clyde | S - Yellow | 52414 |

Add more visuals

Add more data
- we could add the health board names, to make our visual more useful
- we could also get GP practice demographics
Add more data

Re-shape that data

Strengths
- by far the easiest way of producing simple interactive data products
- great tools for tidying data and wranging data sources
- shines as a way of data hubbing / self-service data
- happy with bigger data than Excel can handle
- nice iterative workflow
- scales well, especially if you’re working for a very large number of users
- potential to manage complex and sensitive data on existing infrastructure
Weaknesses
- terminal analysis product. Don’t expect/try to get data out of Power BI, it’s absolutely not designed to be used for that
- for most of us, users need to be licenced - or expect to spend extra money to make dashboards available to non-licenced users
- cross-organisation use is really messy
- adding extra features (real-time data, e.g.) can be complicated and expensive
- steepening pain curve. Easy to start projects, but more involved analysis is messy
- complex IG landscape - reminder for NHS colleagues about national guidance on Power BI
- low-code, rather than no-code
