We've been doing this for 18 months or so. Unfortunately our LIS does not allow repeat requests to be targetted to a queue so the request form is put in a box for checking. The data entry staff type in a biochemistry 'note' which is answered with a coded comment e.g. 'Repeat TSH not available within 4 weeks'. At the vetting stage, if the requester has access to view results electronically, it is left as this. If the requesting professional does not have access e.g. a GP when the last request was from OPD, the most recent result is appended.
 
We have implemented this for TSH, HbA1c, Digoxin, Troponin T, AFP, TPMT and haemochromatosis genotyping (invaluable for genetic tests). We get around flagging requests where the previous result was insufficient by using the 'note' to report insufficient samples. We have a few exceptions to the rule e.g. HbA1c in pregnant ladies with diabetes are input and the flag ignored by the data entry staff. The process has been fairly well received as long as the previous result is available.

We had planned to use some requesting rules with the 'new' WinPath system, but I had been worried out rejecting requests where the previous result was e.g. 'insufficient'.  Sending the rejects to a queue would seem to get round this.  Do you have to spend much time checking this queue?

Subject: Re: Duplicate requesting

Our system (Sysmed=Woodard) permits the trapping of repeat requests within a given time.
 
We routinely trap repeat TSH and Cholesterol within 1 month and a number of other tests at other time intervals e.g.LFTs within 3 days.
 
Trapped requests are queued for inspection and let through if necessary.
 
Unfortunately the methods one can use tend to be LIS specific, but I'm happy to expand on this if required.

Subject: Duplicate requesting

Is anyone else using their LIS to limit duplicate requesting? We have recently started to trial this and would like to expand its use.
I'd be very keen to learn of any potential pitfalls or benefits of using IT in this way.
We are begining by having the duplicate requests diverted to an authorisation queue for vetting. Is this how others have tackled it?
 
All the best
