Diabetes complications, Diabetic foot, Osteoarthropathy
Brief summary
Charcot foot, characterized by progressive destructive damage to bone, soft tissue and tendons, involving joint dislocation in the ankle and foot, is a complication of diabetes that is still poorly understood by patients and caregivers. The clinical signs are non-specific and it is therefore largely underestimated due to a delay in diagnosis/lack of diagnosis.This study will be on a prospective multicenter cohort of patients with chronic Charcot's foot in France to evaluate the evolution of quality of life at 2 years, as well as predictive factors in order to better identify subjects with the worst outcome among this population. Our hypothesis is that, in patients with chronic Charcot foot, the deterioration in quality of life over time is primarily related to loss of foot and ankle functionality, foot and ankle deformity and the presence of foot wounds/comorbidities/severe diabetic complications.
Detailed description
Diabetes mellitus is a chronic disease, representing a major public health problem. An estimated 537 million people have diabetes. Charcot foot, also known as neurogenic osteoarthropathy (NAO), is one of the complications of diabetes secondary to diabetic neuropathy. It is characterized by progressive destructive damage to bone, soft tissue and tendons, involving joint dislocation in the ankle and foot. Charcot foot is a complication of diabetes that is still poorly understood by patients and caregivers, with non-specific clinical signs. It is therefore largely underestimated, since it is estimated that there is a delay in diagnosis or a lack of diagnosis in approximately 25% of cases. The objective of our study is to conduct a prospective multicenter cohort of patients with chronic Charcot's foot in France in order to evaluate the evolution of the quality of life at 2 years, as well as its predictive factors. In this way, we will be better able to identify the subjects with the worst outcome among the chronic Charcot foot population. Our hypothesis is that the deterioration in quality of life over time in patients with chronic Charcot foot is primarily related to loss of foot and ankle functionality, foot and ankle deformity, the presence of foot wounds and/or comorbidities or severe diabetic complications.
Interventions

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Results of the SF36 questionnaire at inclusion | Day 0 | The SF-36 questionnaire is a quality of life questionnaire that includes 36 questions divided into 8 different categories (physical functioning, limitations due to physical condition, physical pain, perceived health, vitality, social functioning or well-being, limitations due to mental condition, mental health). These 8 dimensions are used to calculate two scores on the quality of life of individuals: the physical composite score and the mental composite score. The higher the score, the greater the capacity. It is self-administered and takes less than 10 minutes. Higher scores indicate better quality of life. The French version has been validated and has satisfactory psychometric properties. Score from 0 to 100. |
| Results of the FAAM-F questionnaire at inclusion | Day 0 | The FAAM is a self-administered questionnaire that measures physical function of the foot and ankle. It is adapted and validated in the evaluation of diabetic foot disease. It consists of an assessment of activity of daily living and a sports assessment.

Each condition is assigned a score of 1, 2, 3, or 6, depending on the risk of dying associated with each one. Scores are summed to provide a total score to predict mortality. Clinical conditions and associated scores are as follows: 1. each: Myocardial infarct, congestive heart failure, peripheral vascular disease, dementia, cerebrovascular disease, chronic lung disease, connective tissue disease, ulcer, chronic liver disease, diabetes. 2. each: Hemiplegia, moderate or severe kidney disease, diabetes with end organ damage, tumor, leukemia, lymphoma. 3. each: Moderate or severe liver disease. 6 each: Malignant tumor, metastasis, AIDS. |

Precarity of patients with chronic Charcot foot. | Day 0 | The EPICES (Evaluation de la précarité et des inégalités de santé dans les Centres d'examens) score is an individual indicator of precariousness that takes into account the multidimensional nature of precariousness. The main interest of the EPICES score is to capture populations which, while not covered by traditional administrative indicators of precariousness present the same health risks. A threshold of 30 is considered as precariousness according to EPICES. |
| I. Depression according to the PHQ-2 self-questionnaire | Day 0 | The purpose of the PHQ-2 is to screen for depression in a first-step approach. there are 2 questions referring to the patient's feelings over the previous 2 weeks ( 0 = Not at all and 3 = Nearly every day). A PHQ-2 score ranges from 0-6 and a score of 3 is the optimal cutoff point when using the PHQ-2 to screen for depression. If the score is 3 or greater, major depressive disorder is likely and the PHQ-9 questionnaire should then be used. |
| I. Depression according to the PHQ-9 self-questionnaire | Day 0 | The PHQ-9 questionnaire is a set of 9 questions referring to the patients feelings over the previous 2 weeks with answers ranging from 0 = Not at all to 3 = Nearly every day.
