Brief 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.

Outcome Measures

Primary Outcomes (6)

• Recruitment rate

  Proportion of patients providing informed consent among those assessed for eligibility

  Continuous during recruitment period (up to 8 weeks)

• Retention rate

  Proportion of included participants completing planned assessments

  At discharge and 4 months post-discharge

• Data completeness

  Proportion of completed data among expected assessments

  Through study completion, up to 4 months post-discharge

• Fidelity of intervention delivery

  Assessed via structured observations and logs reported as proportions and descriptive measures of adherence, dose, frequency, and quality

  Continuously targeted observations during the 8-week intervention period

• Patient acceptability of the intervention

  Assessed using semi-structured interviews assessing perceived relevance, appropriateness, and burden of the intervention

  At discharge

• Healthcare professional acceptability of the intervention

  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

  The last four weeks of the intervention period or shortly thereafter

Other Outcomes (12)

• Basic mobility independence

  Daily from inclusion until discharge

• In-hospital mobility

  Postoperative day 2, 4 and 6

• Pre-fracture mobility

  At inclusion and 4 months post-discharge

Study Arms (1)

HIP-ME-UP mobility intervention

EXPERIMENTAL

Participants receive the HIP-ME-UP multicomponent mobility intervention during hospitalization after hip fracture surgery. The intervention aims to support early and frequent mobility through structured mobility support, supervised exercise, and encouragement of mobility-related daily activities.

Behavioral: HIP-ME-UP mobility intervention

Interventions

HIP-ME-UP mobility intervention BEHAVIORAL

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.

Eligibility Criteria

• Age: 60 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Age ≥ 60 years.
• Admitted to one of the two acute orthopedic wards at Copenhagen University Hospital Hvidovre (CUHH) following hip fracture surgery.
• Pre-fracture Cumulated Ambulation Score (CAS) (by recall) ≥ 3 points, indicating independence or assisted independence in basic mobility activities such as bed transfer, chair transfer, and indoor walking.
• Participants may be included if they are able to provide informed consent independently or if informed consent is obtained from a legally authorized proxy (e.g., caregiver or close relative) in cases of cognitive impairment. This applies to both Danish- and non-Danish speaking patients. Non-Danish speakers may be included with support from translated study materials and assistance from relatives or interpreters, where appropriate.

You may not qualify if:

• Non-ambulatory before the fracture, e.g. permanently bedbound or wheelchair-dependent.
• Terminal illness with limited expected survival.
• Weight-bearing restrictions.
• Multiple fractures or suspected pathological fractures (e.g. related to malignancy).
• Clinically unstable or presenting conditions in which early mobilization is contraindicated.
• Patients who previously participated in HIP-ME-UP Study 4, ensuring that recipients in Study 6 have not been prior HIP-ME-UP study participants or patient partners.
