OpenPathology aims to make an innovative new tool showing comparative data on pathology test requests made by GPs.

It aims to:

  1. Build infrastructure to securely import, store and analyse pathology datasets;
  2. Normalise the data;
  3. Create a website to appropriately display data on testing rates for each major test type;
  4. Create standard measures with clinicians;
  5. Deploy and iteratively improve throughout agile development cycles.

Bennett Institute – What We Did Last Year!

Most people share their end of year roundup during late December when everyone is too full of cake to read. Now you’re back in the saddle, here’s our roundup of everything the Bennett Institute threw out into the world over the previous 12 months! OpenPrescribing went from strength to strength, with over 135,000 unique users last year. We now have over 80 measures of prescribing safety, efficacy and cost-effectiveness and have been working on new types of measures and alerts to identify “outlier” prescribing, such as with zuclopenthixol.

OpenPathology: Issues with reference ranges — Part 3

This is the third instalment in our series of commentaries on using reference ranges to interpret pathology test results. Reference ranges vary between labs Classically, the reference range is defined statistically: it is the interval within which 95% of the values of a healthy reference population fall into. Therefore 2.5% of the time, healthy people will have (for example) haemoglobin concentrations less than the lower limit, and 2.5% of the time it will be over the upper limit.
