The use of the algorithm format as a way to represent patient management was chosen based on the understanding that such a format may promote more efficient diagnostic and therapeutic decision making; it also has potential to change patterns of resource use. Although the Work Group recognizes that not all clinical practices are linear, the simplified linear approach depicted through the algorithm and its format allows the provider to assess the critical information needed at the major decision points in the clinical process. It includes: An ordered sequence of steps of care Recommended observations and examinations Decisions to be considered Actions to be taken For each VA/DoD CPG, there is a corresponding clinical algorithm that is depicted by a step-by-step decision tree. Standardized symbols are used to display each step in the algorithm, and arrows connect the numbered boxes indicating the order in which the steps should be followed.[28] Shape Description Rounded rectangles represent a clinical state or condition Hexagons represent a decision point in the guideline, formulated as a question that can be answered Yes or No Rectangles represent an action in the process of care Ovals represent a link to another section within the guideline Appendix K contains alternative text descriptions of Module A and Module B.
