Disease management programs require constant monitoring to assure quality and address problems efficiently. To initiate continuous quality improvement in a disease management program, there are several methods available to identify potential problems within the program that may be affecting quality. Some common quality improvement instruments include the Plan-Do-Check-Act model, check sheets, and so forth. Whatever model is used, Statistical Process Control using flow charts, histograms, Pareto diagrams, scatter diagrams, control charts, and cause-and-effect diagrams provides a better understanding about how the organization\u27s processes are functioning. These tools facilitate problem recognition and allow an organization to meet established standards of quality in the most economical manner
