RESUMO

BACKGROUND: The development of optimal strategies to treat impaired mobility related to ageing and chronic disease requires better ways to detect and measure it. Digital health technology, including body worn sensors, has the potential to directly and accurately capture real-world mobility. Mobilise-D consists of 34 partners from 13 countries who are working together to jointly develop and implement a digital mobility assessment solution to demonstrate that real-world digital mobility outcomes have the potential to provide a better, safer, and quicker way to assess, monitor, and predict the efficacy of new interventions on impaired mobility. The overarching objective of the study is to establish the clinical validity of digital outcomes in patient populations impacted by mobility challenges, and to support engagement with regulatory and health technology agencies towards acceptance of digital mobility assessment in regulatory and health technology assessment decisions. METHODS/DESIGN: The Mobilise-D clinical validation study is a longitudinal observational cohort study that will recruit 2400 participants from four clinical cohorts. The populations of the Innovative Medicine Initiative-Joint Undertaking represent neurodegenerative conditions (Parkinson's Disease), respiratory disease (Chronic Obstructive Pulmonary Disease), neuro-inflammatory disorder (Multiple Sclerosis), fall-related injuries, osteoporosis, sarcopenia, and frailty (Proximal Femoral Fracture). In total, 17 clinical sites in ten countries will recruit participants who will be evaluated every six months over a period of two years. A wide range of core and cohort specific outcome measures will be collected, spanning patient-reported, observer-reported, and clinician-reported outcomes as well as performance-based outcomes (physical measures and cognitive/mental measures). Daily-living mobility and physical capacity will be assessed directly using a wearable device. These four clinical cohorts were chosen to obtain generalizable clinical findings, including diverse clinical, cultural, geographical, and age representation. The disease cohorts include a broad and heterogeneous range of subject characteristics with varying chronic care needs, and represent different trajectories of mobility disability. DISCUSSION: The results of Mobilise-D will provide longitudinal data on the use of digital mobility outcomes to identify, stratify, and monitor disability. This will support the development of widespread, cost-effective access to optimal clinical mobility management through personalised healthcare. Further, Mobilise-D will provide evidence-based, direct measures which can be endorsed by regulatory agencies and health technology assessment bodies to quantify the impact of disease-modifying interventions on mobility.

RESUMO

OBJECTIVES: To establish nationally representative estimates of the use of agents to treat Alzheimer's disease and related dementias (ADRDs) and related behavioral symptoms in Medicare beneficiaries and to describe medication use according to residential status and other patient characteristics. DESIGN: Cross-sectional prevalence study. SETTING: Community and various long-term care (LTC) settings. PARTICIPANTS: Twelve thousand six hundred ninety-seven beneficiaries from the 2002 Medicare Current Beneficiary Survey (MCBS), of whom 11,593 were community dwelling and 1,104 resided in various LTC settings. MEASUREMENTS: ADRDs were identified according to International Classification of Diseases, Ninth Revision, codes in Medicare claims and self- and proxy reports. Medication use was derived from self-reports (community) and extracts of facility medication administration records (LTC). RESULTS: In 2002, an estimated 3.4 million Medicare beneficiaries were diagnosed with ADRDs (8.1%), of whom 58.9% resided in the community (prevalence rate=5.1%) and 41.1% resided in LTC facilities (prevalence rate=57.2%). Use of antidementia drugs was similar across settings, with 24.7% of subjects with dementia in the community and 26.3% of those in LTC receiving prescriptions for donepezil, galantamine, or rivastigmine. Use of haloperidol was comparable (and low) in both settings. Use of atypical antipsychotics, especially risperidone, olanzapine, and quetiapine, was much higher in LTC residents (21.0%, 11.9%, and 7.1%, respectively) than in the community (5.1%, 4.0%, and 2.3%). CONCLUSION: The prevalence of ADRDs in LTC settings is much larger than in the community, but there is little difference in the proportions receiving antidementia drugs, although LTC residents are more likely to be treated with atypical antipsychotics (risperidone, olanzapine, and quetiapine), presumably for behavioral symptoms.
