[Level of attention of the classified supplies as Z in the hospital universitário from USP].

The lack of the consumption materials in hospital units is a faced difficulty for health professionals. Some tools of the supplies' management are being incorporated with the purpose to minimize these lacks, between them the XYZ materials classification which is based on the operational importance of supplies. It allows fixing levels of attendance (LA) and levels' lacks (LL) to different supplies. The objectives of this study was to raise the number of non-observed requests of the Z's supplies, to calculate LA and LL of the 20 supplies that were more non-observed and to know were the possible causes that had led to these lacks. The sample of 747 non-observed requests had shown that of 572, 39.7% had presented some lack. The delay in the delivery for the supplier was the most representative cause with 39%. The LAs had varied from 92.11% to 27.08% and, the LLs from 7.89% to 72.92%.
