About this trial

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 criteria

This trial does not accept healthy volunteers

Qualifiers

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.

Disqualifiers

Non-ambulatory before the fracture, e.g. permanently bedbound or wheelchair-dependent.

Terminal illness with limited expected survival.

Post-operative weight-bearing restrictions precluding mobility activities.

Multiple fractures or suspected pathological fractures (e.g. related to malignancy).

Trial design

Design model

Single group

Treatments tested in this trial

  • 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.

Trial outcomes

Primary outcomes

1

Recruitment rate

Proportion of patients providing informed consent among those assessed for eligibility

Time frame
Continuous during recruitment period (up to 8 weeks)
2

Retention rate

Proportion of included participants completing planned assessments

Time frame
At discharge and 4 months post-discharge
3

Data completeness

Proportion of completed data among expected assessments

Time frame
Through study completion, up to 4 months post-discharge
4

Fidelity of intervention delivery

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

Time frame
Continuously targeted observations during the 8-week intervention period

Secondary outcomes

Other outcomes

1

Basic mobility independence

Assessed using the Cumulated Ambulation Score, range 0-6, higher scores indicate better mobility independence

Time frame
Daily from inclusion until discharge
2

In-hospital mobility

Assessed using Acute Care Mobility Assessment measuring walking activity during the previous 24 hours across three mobility levels (room, ward corridor, outside ward). Higher scores indicate greater in-hospital mobility

Time frame
Postoperative day 2, 4 and 6
3

Pre-fracture mobility

Assessed using New Mobility Score, range 0-9, higher scores indicate better pre-fracture mobility

Time frame
At inclusion and 4 months post-discharge
4

Pain intensity

Assessed using Verbal Rating Scale, range 0-4, higher scores indicate greater pain intensity. Pain will be assessed at rest and during activity

Time frame
On inclusion and on postoperative day 2, 4, and 6
