I have never had the sort of job where you can tell someone what you do in one word and they have at least an inking of what it is. I've always been vaguely envious of the teachers/nurses/doctors/solicitors I know who can do this.
So: I am an NHS clinical coder.
This means that when someone is discharged from a hospital admission, their notes come to the team I work with. We go through the notes, decipher the doctors' handwriting and determine the diagnoses of the patient (not just what they came in for, but co-morbidities as well) and any procedures carried out.
This information is then (with the help of some massive books) translated into codes which are entered onto a digital system.
This information is then used for budgeting and planning, and (this is the bit I find fascinating) for epidemiology and health trends analysis.
For example: we know things like how often women whose labour is induced go on to have forceps deliveries, or how often people with certain co-morbidities have worse outcomes from particular illnesses or procedures, in part from analysis of the coded data my colleagues and I produce.
What do you do?
