SWORM Project #1

Does the start sign of the patient influence intraocular pressure across four different sites in the South West of England.

 

Method:

Collect IOP measurements and date of birth for all patients seen within a 48 hour time period across the South West. Exclusion criteria – any patients on pressure lowering medication or who have had previous glaucoma surgery (trabeculectomy/SLT/ALT/other).

 

Why do it?

Easy to collect data

● Generate interest and enthusiasm with the trainees

● Allow a ‘shake down’ with snag fixing along the way in low stakes project

● Fun

● Should be easy to present

● Quick to analyse

● Cheap

● We collect the data anyway during the course of our usual examinations

● No patient identifiable information required

● No ethical approval required

● Proof of principle that SWORM is a viable and a good concept for ‘real’ scientific

research across the ophthalmic sciences, paving the way for more ambitious

projects.

 

Background

Bias and poor study design leads to bad information

Bad information → bad decisions by clinicians

Bad decisions by clinicians → harm to patients

Publication bias → Bad information

Bad information → bad decisions by clinicians

Bad decisions by clinicians → harm to patients

Post hoc analysis with subgroup analysis is bad practice → bad information

Bad information → bad decisions by clinicians

Bad decisions by clinicians → harm to patients

What if a correlation is found between star sign and the IOP?

Correlation does not equal causation!

What if no correlation is found? Present anyway, it will be the ideal forum for discussing

publication bias.
