Measuring the Burden of
Musculoskeletal Disease
Musculoskeletal Conditions and Injuries: Status and Goals
United States Bone and Joint Decade
Definitions: Burden of disease: refers to the combination of
the incidence/prevalence, impact (in terms of quality of life and disability), and cost of musculoskeletal conditions.
Bone and Joint Decade: a worldwide coalition to document the burden of musculoskeletal conditions and to improve care through patient empowerment, communication and research.
Background
In 1999 and 2000 two conferences, hosted by the American Academy of Orthopaedic Surgeons, were organized to determine the burden of disease of musculoskeletal conditions in the United States on American society. For many, this was the first activity of the U.S. Bone and Joint Decade, and its most important initial charge. A good knowledge of the prevalence of musculoskeletal conditions provides the foundation to support education, research and advocacy activities of the Decade.
Background
This slide set provides a summary of the findings of the two conferences. After viewing the slide set, refer to the section “Resources” for more comprehensive data, and to obtain materials mentioned in the slide set.
Reasons for the Conference Mutual interest in burden of disease Lack of comprehensive data and agreement
concerning measures of this burden Importance relative to research funding (US
Congress, National Institutes of Health) Emergence of Bone and Joint Decade Improved prevention and treatment
Conference Goals
Identify and discuss burden of disease measures for musculoskeletal conditions
Describe international efforts Produce a preliminary plan to improve
measurement of the burden of musculoskeletal disorders
Identify ways to support the Bone and Joint Monitor Project

Impact of an Aging Population:
Predicted growth in the next 30 years: 1 in 5 Americans will be 65 or older by 2030 [up from 1 in 8 in the year 2000]
About 65 million people in 2030 Incidence of musculoskeletal conditions will
grow proportionally
