Feasibility of a Co-designed Mobility Intervention After Hip Fracture Surgery

Condition(s) studied

Investigational drug(s) / intervention(s)

HIP-ME-UP mobility intervention: A multicomponent intervention designed to support early and frequent mobility during hospitalization after hip fracture surgery. The intervention includes a dedicated porter supporting mobility activities, standardized training concept to promote independence in bed transfer, group-based exercise supervised by physiotherapists, and encouragement of personal activities of daily living in the bathroom. The intervention is delivered by physiotherapists, occupational therapists, and porters as part of routine clinical care during hospitalization.

Study summary

This clinical study examines whether a co-designed mobility intervention can be delivered in routine hospital care after hip fracture surgery.

Hip fracture is a common and serious condition among older adults and is associated with loss of independence, complications, and increased mortality. During hospitalization, many patients remain inactive, even though early and frequent mobility is considered important for recovery.

The HIP-ME-UP intervention was developed in collaboration with healthcare professionals, patients, caregivers, and hospital management. It aims to support early mobilization, independence in basic mobility activities such as getting in and out of bed and increased physical activity during hospitalization.

The study will investigate whether the intervention is feasible to deliver in routine clinical practice, whether it is delivered as intended, and whether it is acceptable to patients and healthcare professionals.

Participants admitted after a hip fracture surgery will receive the intervention during hospitalization. Researchers will collect information on recruitment, retention, fidelity, acceptability, and mobility-related outcomes. Approximately 25 participants will be included.

The results will help determine whether a larger effectiveness study should be conducted.

Eligibility

Primary outcome measure(s)

• Recruitment rate — Continuous during recruitment period (up to 8 weeks)
  Proportion of patients providing informed consent among those assessed for eligibility
• Retention rate — At discharge and 4 months post-discharge
  Proportion of included participants completing planned assessments
• Data completeness — Through study completion, up to 4 months post-discharge
  Proportion of completed data among expected assessments
• Fidelity of intervention delivery — Continuously targeted observations during the 8-week intervention period
  Assessed via structured observations and logs reported as proportions and descriptive measures of adherence, dose, frequency, and quality
• Patient acceptability of the intervention — At discharge
  Assessed using semi-structured interviews assessing perceived relevance, appropriateness, and burden of the intervention
• Healthcare professional acceptability of the intervention — The last four weeks of the intervention period or shortly thereafter
  Assessed using semi-structured interviews and questionnaire responses based on the Theoretical Framework of Acceptability. All questionnaire items are scored on a 5-point Likert scale (1-5), higher scores depend on the item/domain, with higher scores indicating either greater acceptability for positively framed items or greater burden for negatively framed items
