Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Preventing foot ulcers in people with diabetes can reduce costs and increase quality of life. Despite availability of various interventions to prevent foot ulcers, recurrence rates remain high. We hypothesise that a multimodal approach incorporating a variety of orthotic interventions that matches an individual person's need can reduce ulcer recurrence with beneficial cost-effectiveness and cost-utility.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Multimodal care

Multimodal personalised treatment

Group Type EXPERIMENTAL

Custom-made shoes: pressure-optimized

Intervention Type DEVICE

Pressure-optimized custom-made shoes: evaluated and optimized using in-shoe pressure analysis, and re-evaluated after 6 months.

Custom-made indoor shoes: pressure optimized

Intervention Type DEVICE

Pressure-optimized custom-made indoor shoes: evaluated and optimized using in-shoe pressure analysis, and re-evaluated after 6 months. Specifically designed for indoor use.

Foot temperature monitoring

Intervention Type DEVICE

Personalised at-home daily foot temperature monitoring at high-risk regions.

Education

Intervention Type BEHAVIORAL

Personalised patient education consisting of quantitative feedback on in-shoe pressures, temperature measurements and footwear use and, in addition, motivational interviewing where indicated and needed to improve device use.

Usual care

Usual care as offered to high-risk patients as offered in the Netherlands

Group Type NO_INTERVENTION

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Diabetes mellitus type 1 or 2
* Age 18 years or above
* Loss of protective sensation based on the presence of peripheral neuropathy
* A healed plantar foot ulcer or foot amputation in the preceding 4 years until two weeks before study inclusion
* In possession of custom-made orthopaedic shoes, defined as "Orthopaedic shoes type A" or "Orthopaedic shoes type B" , or Orthopaedic Provision in Regular Footwear (OVAC), according to the Dutch healthcare system
* Ability to provide informed consent

Exclusion Criteria

* Foot ulcer or open amputation site(s)
* Active Charcot's neuroarthropathy
* Foot infection, based on criteria of the PEDIS classification
* Amputation proximal to the metatarsal bones in both feet
* Healed ulcer on the apex of digitus 2-5 as the only ulcer location in the past 4 years, as surgical intervention (flexor tenotomy) is a more likely and guideline-recommended treatment for such patients, rather than the multimodal care under investigation
* Severe illness that would make 12-months survival unlikely, based on the clinical judgment by the physician
* Concomitant severe physical or mental conditions that limit the ability to follow instructions for the study, based on clinical judgment
