Pain assessment
Chronic pain is defined as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in these terms” lasting more than three months (International Association for the Study of Pain). The treatment and evaluation of pain is a strong focus of the PRISMATICS team led by Pr Philippe Rigoard, neurosurgeon at the University Hospital of Poitiers. The PRSIMATICS team has developed an innovative application to evaluate pain objectively and multidimensionally taking into account the associated bio-psycho-social factors. The purpose of this three-patented tool is to better document the health status of patients with chronic pain and provide support to the clinician in the management of their patients.
The pain surface
From a tablet, the patient is asked to color the painful areas on a representation of the body according to the intensity of pain felt: red for very intense pain, orange for intense pain, dark blue for moderate pain and light blue for low pain. A patented process allows to transform in real time the pixels in cm² and thus inform about the pain surface according to the intensity of the pain. In addition to the intensity of the pain felt, the measurement of the painful surface will allow the clinician and the patient to follow the evolution of the pain over time and thus appreciate the effects of a therapy.
The typology of pain
The PRISMap application also makes it possible to inform the surface according to the type of pain felt. The patient is asked to color the painful areas according to the type of pain: mechanical if the pain is induced by movement, or neuropathic if it is characterized by burning, tingling, tingling or external stimulation (heat, touch, etc.). The distribution of the area of the type of pain will help to better inform and guide the therapeutic choice, as well as to better assess the effects of a therapy on one, the other or both components of pain.
The multidimensional assessment of pain
Using pain intensity, pain surface, quality of life questionnaires, emotional state and functional abilities, the PRISMATICS team created a new multidimensional MCRI – Multidimensional Clinical Response Index.
What is the MCRI?
The MCRI (Multidimensional Chronic Pain Index) is a unique index developed from machine learning artificial intelligence and mathematical algorithm to enable a holistic assessment of the patient.
The MCRI includes the following dimensions:
- Pain Intensity: Measures the patient's perception of pain.
- pain surface: Measures the painful body surface.
- Functional capacity: Assesses the impact of pain on the patient's ability to perform daily activities.
- Emotional state: Takes into account levels of anxiety and depression, often associated with chronic pain.
- Quality of life: Measures the overall impact of pain on the patient's quality of life, including psychological and social aspects.
This indicator allows :
- A Holistic Assessment: By integrating several dimensions of pain, the MCRI provides a more complete overview of the patient's health.
- Personalization of Care: Through detailed evaluation, treatments can be better tailored to the specific needs of each patient, thus improving the effectiveness of care.
- A Precise and Sensitive Tool: MCRI has demonstrated high sensitivity and specificity, offering a more reliable assessment of pain and its impacts compared to traditional methods.
The MCRI is a score expressed between 0 (the worst overall health) and 10 (the best overall health).Why Choose the MCRI ?
MCRI represents a significant advance in the assessment of chronic pain. By providing a multi-dimensional assessment, MCRI enables health professionals to better understand and treat patients' pain, thereby improving their quality of life.
