Possibility of using control cards in the improvement of medical services quality

Methods of statistical process control (SPC) provide objective methods of quality control in every manufacturing process, regardless of whether it is manufacture of articles or services. Systematic study of the processes should provide knowledge about their performance and the sources of the deviations from the norm. This article is an attempt to prove the thesis that it is possible to use control charts for variable (continuous) and attribute data in healthcare facilities.
