Sometimes when visiting a hospital or clinic a physician will ask patients to complete health questionnaires in order to get a better idea of what might be troubling them, to determine the effectiveness of a treatment or to predict what illnesses or symptoms a group of people may have. These questionnaires are typically the “pen and paper” type and ask the patient to answer a series of questions regarding his or her health and related matters. Unfortunately these questionnaires are not the best way to obtain a picture of someone’s health because they use the same questions regardless of the person’s condition. A new way of administering health questionnaires involves using a computer. In this new method, the computer chooses the next question based on a patient’s answer to a previous question. Therefore, the questionnaire is “tailored” to the patient and his/her health. The new questionnaire has the potential for assessing patient health more accurately and reliably. Accurately knowing the effectiveness of a medical treatment can help physicians recommend new or different treatments for a patient. Unlike traditional questionnaires, the computerized questionnaire is “tailored” to the patient allowing these new recommendations to better reflect the patient’s condition, which ultimately affect a patient’s level of disability and quality of life.
