Overview of Presentation • Magnitude of the Problem • 30 Years of Evidence from the Baltimore Hip Studies Program: From Observation to Intervention • Consequences • Recovery Patterns • How This Information Informs Intervention Targets
Magnitude of Problem • Estimated 3.9 million hip fractures worldwide annually • Three-quarters of hip fractures are in women • Despite advances in surgical procedures, post-operative care, and long term rehabilitation, hip fractures rank in the top ten worldwide in terms of disability and functional decline.

THE BALTIMORE HIP STUDIES
Goals of Baltimore Hip Fracture Studies To identify, develop, and evaluate strategies to optimize recovery from hip fracture.
The Baltimore Hip Studies (BHS) • Over the past 30 years, the BHS have enrolled and followed more than 4,000 hip fracture patients admitted to 25 Baltimore area hospitals. • Outcomes studied include mortality, functional recovery, and changes in bone mineral density, muscle mass and composition, bone and muscle strength. • Studies have progressed from observational to interventional. • BHS Investigators have collaborated on many single and multi-center studies of hip fracture outcomes outside Baltimore

Other Functional Consequences of Hip Fracture • Loss of Neuromuscular Function (gait/balance) • More Difficulties with Instrumental Tasks (Shopping/housework) • Increase in Cognitive Deficits (50% in hospital; 25% at 2 months) • Increase in Depressive Symptoms (50% in hospital; 25% at 2 months) • Changes in Social Function (visiting with others/participating in activities) Magaziner J, et al.

The Future • Multidisciplinary/multi-component interventions have the potential to improve long term outcomes • Need to design programs using effective components that target individual patient need, and evaluate their combined effect • Packages of interventions need to be tested and translated for use in practice • Need strategies for delivering these interventions in a coordinated manner
Hip fracture is a multi-faceted problem which requires multiple treatments/interventions
