This question comes from Robbie Keith of Summit Laboratory We are in the process of evaluating our QC program. Our techs monitor Levy-Jennings charts for shifts and trends weekly. We would like to know what you consider to define a shift or trend (e.g. how many points are required increasing or decreasing to define a trend?) Consider control rules such as 41s, 10mean, etc., as good indicators of shifts and trends. The number of observations needed increases as the limit approaches the mean of the control material in order to keep the false rejections down. Minimum number of consecutive observations above or below the mean should probably be set as 6. There are some recommendations, particularly in the Germany, to use 7 above or below the mean, or 7 trending consecutively in one direction.

Introduction to Can Tho Medic Hoa Hao General Hospital:

The Mekong Delta is one of the regions with limited access to high-quality medical services. Medical with serious conditions, beyond the local diagnostic and treatment capabilities, requiring several hours of transport to higher-level hospitals with specialized departments for examination and treatment. Understanding this, experienced and dedicated medical professionals have nurtured the dream of bringing high-quality, standardized medical services to Can Tho, a major urban center in the Mekong Delta, comparable to major hospitals and medical centers nationwide. Their targeting is to provide the local population with quick access to advanced, high-quality medical services, shortening treatment times and reducing costs. From this aspiration, the Hoa Hao-MEDIC Can Tho General Hospital was established on September 8, 2016.
