Yesterday afternoon we became aware of a problem that many GP practices using SystmOne were unable to file Pathology results. Yesterday evening the cause of the problem was identified as a change to the Read code set that map Pathology test codes used in the laboratory to those used in practice systems. This new code set was not due to be implemented by the pathology laboratory until November 2014, but a number of Read codes used for very commonly requested tests that had been in use for many years had been withdrawn by HSCIC. As a result, a number of Pathology tests failed to map correctly and could not be filed in the practice systems. We had not been alerted that there were a large number of Deletions (over 340) in this release and had not been made aware of the implementation of the code set by SystmOne.
The code sets were updated on our systems last night ahead of time and we are now working with the local CCGs and SystmOne to determine the best way to resend results if required. Some GP practices have been able to map the Deleted codes to the new versions.
The changes that will have had most impact were:
Remapped local code "PSA", previously mapped to Read code "43Z2.", description
"Prostate specific antigen" to Read code "43Z22", description "Se prostate specific Ag level"
Remapped local code "CALCOR", previously mapped to Read code "44IC.", description
"Corrected serum calcium level" to Read code "44IC0", description "Serum adjusted calcium conc"
Remapped local code "CEA", previously mapped to Read code "44a0.", description
"Carcinoembryonic antigen level" to Read code "44a02", description "Se CEA (carcinoembrynic Ag) lv”
Remapped local code "TPO", previously mapped to Read code "43Gd.", description
"Thyroid peroxidase antibod lev" to Read code "43Gd0", description "Se thyroid peroxidase Ab conc”
Remapped local code "VITD", previously mapped to Read code "4QB46", description
"Total 25-hydroxyvitamin D levl" to Read code "4QB47", description "Serum total 25-OH vit D level"
Remapped local code "PRCRR", previously mapped to Read code "44lD.", description
"Urine protein/creatinine ratio" to Read code "44lzX", description "Rand urine protein:creat ratio"
It is not clear why some of these codes have been changed, as the new versions do not seem to use standardised terminology.
An additional issue noted today is that the new code for “Serum adjusted calcium conc” is not accepting the standard unit of measurement mmol/L (the same as for Serum Calcium) and “Serum total 25-OH vit D level” is not accepting nmol/L.
We are sorry for any inconvenience caused and thank you for your patience while we resolve the issues.
