Evaluation of operation and death statistics at surgical procedures by using attribute control charts
Özet
Statistical Process Control (SPC) is a technique that enables the quality controller to monitor, analyze, predict, control, and improve a production process through control charts. So to use of SPC in medical field is very important. The cases were obtained at the Ondokuz Mayis University Faculty of medicine departments of surgical sciences within two year were evaluated. The outcomes of the operations in these departments were followed throughout twenty-four months. For a surgical procedure has two possible outcomes; a nonconforming product (the patient dies) or a conforming one (the patient survives), the both the death and the alive were accepted as attribute data. The four type of attribute charts were applied to this data. These were p-chart, np-chart, c-chart and u-chart. If the statistical process was an “in-control” or not was tried to determine by the attribute charts. As a result of the statistical processes of these departments were evaluated, this provided easily be viewed the pattern of process. The aim of this research is to use the attribute control charts in medical field (especially hospital performance evaluation) and to show availability of the attribute control charts in medical field. © 2017 OMU.
