Study summary

The study aims to assess foot complications among patients with diabetes in Canada, using patient data collected during diabetes foot assessments performed by the LMC Chiropody Team between February 27, 2018 and April 17, 2019.

Read the detailed description

Among patients with diabetes, one of the major causes of increased morbidity and mortality include lower-extremity complications. Patients who have peripheral neuropathy and peripheral arterial disease are at risk of developing foot ulcers and infection, which can lead to lower-extremity amputations. Adults with diabetes in Canada are 20 times more likely to be hospitalized for a nontraumatic lower limb amputation than adults without diabetes. Thus, the prevention, education and early treatment of diabetes foot complications are an important component of caring for patients living with diabetes.

In addition to neuropathy and peripheral arterial disease, risk factors for developing foot ulcers include increased levels of glycated hemoglobin, onychomycosis, microvascular complications, previous foot ulcer or amputation, structural deformity, and limited joint mobility. To the best of our knowledge, the prevalence of foot complications, such as onychomycosis, and the association of diabetes foot complications with glycemic control and other diabetes risk factors, has not been assessed before in a large sample of Canadian patients. To better understand foot complications among patients with diabetes in Canada, the investigators will retrospectively examine patient data collected during diabetes foot assessments performed by the LMC Chiropody Team. The LMC Chiropody Team is part of LMC Diabetes \& Endocrinology, which is one of the largest endocrine practice groups globally.

Study population

Patients with diabetes at LMC Diabetes \& Endocrinology, who were provided with an initial diabetes foot assessment supported by funding from Bausch Canada. The diabetes foot assessments were performed by the LMC Chiropody Team at seven of the Ontario LMC clinics between February 27, 2018 and April 17, 2019.

Inclusion criteria

  • Age ≥ 18 years
  • Diagnosis of type 1 or type 2 diabetes
  • Under the care of an endocrinologist at LMC
  • Diabetes foot assessment was performed by the LMC Chiropody Team
  • to use patient medical record data for research purposes was provided

Exclusion criteria

Exclusion Criteria:

  • Prior diabetes foot assessment by an LMC chiropodist
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Prevalence of diabetes foot complications: foot ulcer

    Proportion of patients diagnosed with a foot ulcer

    Time frame: 24-hours

  2. Prevalence of diabetes foot complications: onychocryptosis

    Proportion of patients with onychocryptosis

    Time frame: 24-hours

  3. Prevalence of diabetes foot complications: onychomycosis

    Proportion of patients with onychomycosis

    Time frame: 24-hours

  4. Prevalence of diabetes foot complications: onychauxis

    Proportion of patients with onychauxis

    Time frame: 24-hours

  5. Prevalence of diabetes foot complications: hyperkeratosis

    Proportion of patients with hyperkeratosis

    Time frame: 24-hours

  6. Prevalence of diabetes foot complications: foot deformities

    Proportion of patients with foot deformities

    Time frame: 24-hours

  7. Prevalence of diabetes foot complications: neuropathy risk

    Risk for neuropathy will be measured using the modified Toronto Clinical Neuropathy Score (mTCNS)

    Time frame: 24-hours

Secondary outcomes

  1. Diabetes foot assessment risk group

    Diabetes foot assessment risk group will be determined according to International Diabetes Federation (IDF) recommendations. Proportion of patients with low, moderate, high and very high risk will be reported.

    Time frame: 24-hours

  2. Association between foot risk variables and the presence of a foot ulcer

    Risk factors that are associated with foot ulcers in our patient cohort with diabetes will be reported.

    Time frame: 24-hours

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 25, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
