Validation of the French Version of the New Mobility Score (NMS)

Validation of the French Version of the New Mobility Score (NMS) in Hospitalized Patients With Hip Fracture

The incidence of hip fractures in France is 50,000 cases per year among women and 16,000 among men, with a 1-year mortality rate of 20-24%. After a fracture, 10-30% of patients become functionally dependent. The increasing aging of the population and the rise in dependency are likely to worsen the situation of older patients in hospital settings.

Several tools are available to assess functional independence, including the New Mobility Score (NMS), which evaluates mobility through three domains: mobility indoors, mobility outdoors, and shopping activities. The NMS has shown good performance in predicting patient mortality and functional recovery, and its use is recommended in clinical practice. However, the French version of the NMS has not yet been validated.

The French validation of the NMS is important to facilitate its implementation in clinical practice and research, particularly because of its simplicity and the need for rapid assessment tools for healthcare professionals. A French version of the NMS has been translated, and the MOB-SCORE study aims to assess its reliability and validity among healthcare professionals caring for patients with hip fractures.

Inclusion Criteria:

• Patients aged 75 years and older admitted to a hospital department following a hip fracture and treated surgically (osteosynthesis or arthroplasty).
• Type of fracture: pertrochanteric fracture or femoral neck fracture.
• Sufficient proficiency in French to complete the questionnaires.
• Patients affiliated with a health insurance scheme.
• No objection to participate from the patient or the caregiver in case of cognitive impairment.

Exclusion Criteria: no exclusion criteria
