[Histonet] Quality Improvement

[Tony Henwood]

I am a firm believer in lab notebooks.

In it we record all routine maintenance, quality control, solution
preparation (especially dye lot numbers, source etc) as well as
variations to technique caused by vagaries of dye reagents.

Any developmental work is also recorded, trial of new dyes, techniques.
Source of good control material.

I find them of great use especially when I have to repeat a technique
that was ex-manual, ie the odd stain that is requested on a particular
case, done so rarely that it would not appear in a routine stain manual.
It saves me having to re-invent the wheel.

The best method of documenting quality control.

I'm curious as to what others do, if anything, to document corrective
actions or improvements for H&E staining and/or tissue processing.  For
example, I made changes to my biopsy processing program and to my breast
processing program which helped improve the cutting quality of both
types of tissue.  I also had to make various changes to my H&E staining
program when we received hematoxylin and eosin from a new vendor.  Would
you document these changes somewhere?  Would you have one general
binder, for example, that would just be an ongoing log of
changes/improvements, or would you document the changes and keep with
the equipment?  I'm just thinking this might be something that a CAP
inspector would ask for, although I don't see any specific CAP question
on the checklist.
