Abstract: A decision-making aid can be implemented via a computer application and includes a list of medical issues displayed on a medical issue list page. A treatment strategy questionnaire can have each medical issue in a list of medical issues formed as a link to a particular treatment strategy questionnaire. The treatment strategy questionnaire includes a list of questions, and each question of the list of questions can be displayed on a question page. A prompt receives an answer to each question. A query is preferably presented as a yes button and a no button. The prompt is a yes or no prompt corresponding to the yes button and the no button. The yes button provides a yes prompt response, and the no button provides a no prompt response.
