Key facts

PhenX - fracture history protocol 170901

This protocol is divided into two parts. Part I consists of the Study of Osteoporotic Fractures (SOF) Fractures and Falls HistoryHistory of Fractures Questionnaire, which is a self-administered questionnaire to assess the location of the respondent's broken bone(s) and the age(s) at which the break(s) occurred. Part II contains the Framingham Osteoporosis Study Fracture Assessment form to confirm the respondent's self-reported fracture history. Although the Fractures and Falls History: History of Fractures Questionnaire was originally developed for women ages 65 and older, the PhenX Skin, Bone, Muscle and Joint Working Group recommends that it could be used on adults of all ages. Self-report questionnaires have been found to have variable rates of false positives. These rates are decreased when self-reports are coupled with confirmation/adjudication. Therefore, the Working Group recommends that the Fractures and Falls History: History of Fractures Questionnaire be corroborated with a medical record confirmation and adjudication from the Framingham Osteoporosis Study. This study also includes a fracture index to classify fracture locations.
