In this paper, a brief outline of the evolution of the statistical techniques for the measurement of quality is firstly sketched. At the same time, the need for multivariate procedures is justified from both methodological and application points of view and a proposal of non parametric control charts is shown. The attention is then focused on visualising and monitoring quality. The peculiar fea...

Objective: Diabetes is a chronic disease that causes severe side effects in patients. According to the previous studies, the incidence of depression and anxiety is higher among patients with diabetes type 2. The present study was conducted with the aim of examining the effectiveness of mindfulness-based stress reduction program and conscious yoga on depression, anxiety and stress in patients wi...

Due to the rapid change of technology along with advanced data-collection systems, the simultaneous monitoring of two or more quality characteristics (or variables) is necessary. Multivariate Statistical Process Control (SPC) charts are able to effectively detect process disturbances. However, when a disturbance in a multivariate process is triggered by a multivariate SPC chart, process personn...

Most multivariate quality control procedures evaluate the in-control or out-of-control condition based upon an overall statistic, like Hotelling’s T. Although T is optimal for finding a general shift in mean vectors, it is not optimal for shifts that occur for some subset of variables. This introduces a persistent problem in multivariate control charts, namely the interpretation of a signal, wh...

background: sputum smear examination is the basis of diagnosis of tuberculosis and quality control for the correct diagno­sis of tuberculosis is necessary. this study was a method survey and performed with 930 smears with the aim to compare the confidence rate of sputum smear examination reported by one laboratory technician with the findings reported by two techni­cians in a tuberculosis scree...

We suggest better methods for monitoring the diagnostic and treatment services of health care providers. In particular, we examine the construction and use of industrial quality control methods as applied to the health care providers in both the prevention and cure for infectious diseases and the quality performance of health care providers especially in the area of acute care. We suggest imple...
