CLINICAL DECISION SUPPORT MODEL FOR ASSESSING FOOT CONDITIONS AND WOUNDS

Priority Claim:

[0001] This application claims priority from the provisional application numbered 202141010133 filed with Indian Patent Office, Chennai on 10^th March 2021 and post-dated to 10^th September 2021 entitled “ Clinical decision support model for assessing foot conditions and wounds’", the entirety of which is expressly incorporated herein by reference.

PREAMBLE TO THE DESCRIPTION:

[0002] The following specification particularly describes the invention and the manner in which it is to be performed:

DESCRIPTION OF THE INVENTION

Technical field of the invention

[0003] The present invention relates to approaches for assessing wound in patients, and more particularly for assessing wound in the patients who are suffering from Type-2 diabetes and resulting conditions.

Background of the invention

[0004] As may be understood, a substantial proportion of the population in India is suffering from diabetes. Diabetes in a majority of cases results in development of foot related conditions, such as a Diabetic Foot Ulcer. However, any failure to detect and treat such conditions in a timely manner may result in amputation. [0005] Although appropriate intervention techniques may be employed to prevent amputation, such techniques are usually commonplace in advanced medical institutions but may not be available for remote or rural locations. In such locations even though a certain level of medical care is performed, the clinicians may not apply podiatric clinical recommendations and protocols that are employed in metropolitan cities in India. Non-availability of appropriate care in the semi-urban and rural areas leads to delayed or frequent visits by the patients to tertiary care hospitals in the metro cities, leading to late diagnosis and high costs, and in the end non-healing ulcers and amputations.

[0006] As described above, diabetes may impact conditions of patients’ feet, which have to be accordingly managed. Failure to manage or take appropriate intervention measures may lead to amputation. The fact that such intervention techniques are usually commonplace in advanced medical institutions in metros, does not benefit rural or remote locations which may also have a substantial population which may require adequate treatment and support. Such issues may get further compounded due to clinicians or medical personnel not being informed or trained of the correct podiatric clinical recommendations and protocols that are to be employed while managing foot ulcers or such similar conditions.

[0007] It may be noted that even in cities where appropriate interventions may be provided to ailing patients, such interventions have to be performed under the guidance and instruction of podiatric specialists. In such cases, decision as to the appropriate intervention to be affected is determined and based on a visual inspection and physical examination conducted by the podiatric specialists. This again may be not be possible to conduct through teleconsultations, and hence, becomes largely dependent on the presence and availability of the specialists.

[0008] Furthermore, there do not exist any appropriate approaches that may preempt the occurrence or onset of foot related conditions. As a result, onset or occurrence of a foot ulcer may be prolonged or even prevented if appropriate interventions, such as offloading through custom orthotics, custom footwear, or off the shelf orthotics for patients use. However, no effective approaches presently exist which may efficiently assess posture, gait related attributes of the feet of a diabetic patient to determine likelihood of onset of foot injuries and neither do they provide a prescriptive footwear for overcoming such conditions.

[0009] For instance, a patent application number US10303796B2 provides a wound assessing method and system to provide a convenient, quantitative mechanism for diabetic foot ulcer assessment. The method for assessing chronic wounds and ulcers comprises capturing an image of a body part including a wound area and analysing the image to extract a boundary of the wound area. The system performs colour segmentation within the boundary, wherein the wound area is divided into a plurality of segments, each segment being associated with a colour indicating a healing condition of the segment and the wound area is evaluated.

[0010] For instance, a patent application number US20200330028A1 provides a system and method for facilitating analysis of a wound in a target subject, wherein the method comprises obtaining one or more digital images of at least a portion of the wound; extracting a plurality of feature vectors from the one or more digital images; and identifying, using a first trained deep neural network, a type of wound tissue based on the plurality of extracted feature vectors.

[0011] Hence there is a need for a system and method for training a clinical decision support model for assessing foot conditions and any chronic wound ulcers.

The target wound data is subsequently shared with the computing system for analysis. Further, the target posture data contains at least one image of foot of the patient depicting gait and posture of the foot.

[0017] Further, the detection engine further provides multiple intervention approaches, wherein the intervention approaches comprise a mapping between a determined stage of the wound and the corresponding intervention measure.

The detection engine further comprises posture corrective measures, wherein the posture corrective measures contain a variety of suggestive actions to be prescribed for a patient to either prolong or prevent occurrence of any foot injuries.

[0018] The present invention is advantageous as it provides a system and method to facilitate assessment of posture related attributes, drive transformation in foot management through the novel clinical decision support system (CDSS) enabled through artificial intelligence driven diagnostics, preventive, curative and rehabilitative care. Further, the present invention prevents amputation in above 80% of the patients suffering from any chronic ulcer. The system enables monitoring and management of foot health in the clinic or at home, using conventional computing devices, such as any electronic device- enabled conversational application combined with an image capturing device to generate high-resolution images and videos of the foot and the gait of the patient.

[0019] Further, the system provides a comprehensive objective transparent assessment of the patient wound healing process and results in harmonizing the care process across geographies, hence improving the quality of the care even for remote and rural areas where the access of specialists is not available. Another advantage of the present invention is that the system facilitates ease of use by any clinician at any part of the world, having a network connection and any electronic device with local language support.
