Though you might like to see what the balance of policy is across the UK from the use of data mining techniques.
The attached jpeg shows displays of test rates per 1000 patients for data aggregated at PCT level. Each bar is a PCT. The data was extracted anonymously from PMIP as part of the safety audit (still ongoing - see www.ychi.leeds.ac.uk/pmipunits<http://www.ychi.leeds.ac.uk/pmipunits>) and is a short snapshop based on >1m test reports. We can assume PCTs are about equivalent coverage to labs though of course there will be overlap - one wonders how the poor clinicians and patients cope with the variance at the boundaries.
The upper panel shows TSH usage and the lower panel fT4 usage. The visualisation suggests about half the country is using parallel TSH/fT4 and half sequential protocols. By mapping these data to rates of 'missed' / 'late diagnosed' hypopits from HES we could probably answer the clinical effectiveness question once and for all. Hardly anyone is still sending TT4. The variance in terms of tests per patient gets worse as you drill down through PCTs to GP practices just as Stuart Smellie has shown. Whether the patient outcomes are affected is a moot point and cries out for some R&D.
Some of this data is now in the printed version of the Atlas of Variation - see http://www.sepho.org.uk/extras/maps/NHSatlas2011/atlas.html
The dataset includes thyroid ref ranges etc too - Julian Barth has been commissioned by Muir Gray to look into this in depth.

I'd be interested in how others organise this, but I'm more concerned about staff cost than delay in reporting.
For us:
The cascade overwhelmingly schedules the next assay without human intervention while the specimen is still on the track so there is no staff cost. (Siemens analysers and track.)
We are analysing specimens from primary care 24 x 7 without cut-offs so the delay is typically "one more assay" and would very rarely be perceptible by the GP.

Does anybody also have data regarding the processing delay introduced ?
This will depend on the number of samples needing reflex testing, with consequential doubled analysis time, as well as all reflexable samples having to be held in results pending space prior to first results availability.

PS: There's no theoretical reason why population reference intervals should be the best decision limits for cascading further assays.

Good morning.
There's lots on this in the literature. I suggest you start with Barth's surveys published in Annals. There may also be something on current diversity of practice in recent Keele benchmarking reports.
In Oxford we start with TSH only (except in certain defined groups) and use on-analyser cascade rules from there.
Do you have computerised requesting by clinicians in either or both of primary care and secondary care that you can use as a platform for the rules?
Does anyone have experience of using this platform to implement different pathways for diagnosis and monitoring?
For primary care I am unconvinced by the argument about picking up hypopituitarism making it necessary to start with two assays in all patients. Does anyone have relevant figures on incidence of disease detected in this way or cost-effectiveness?

Morning all,
I would be grateful for a bit of advice from the collective. Like everywhere, we are under increasing budget pressures and one idea that has come up is to offer only TSH as our first line thyroid panel. I find this a bit concerning as, even if you reflex FT4 when TSH is outside the reference range, we will no longer pick up hypopit patients. I would be interested to hear your thoughts on this, particularly from anyone who already has this or a similar strategy in operation
Happy to summarise responses and feed back.
Many thanks,
Laura
