BACKGROUND Chronic ulcers, and especially ulcers affecting the lower extremities and their protracted evolution, are a health problem with significant socio-economic repercussions. The patient's quality of life often deteriorates, leading to serious personal problems for the patient and, in turn, major care challenges for healthcare professionals. Our study proposes a new approach for assisting wound assessment and criticality with an integrated framework based on a Mobile App and a Cloud platform, supporting the practitioner and optimising organisational processes. This framework, called Clinicgram, uses a decision-making support method, such as morphological analysis of wounds and artificial intelligence algorithms for feature classification and a system for matching similar cases via an easily accessible and user-friendly mobile app, and assesses the clinician to choose the best treatment. OBJECTIVE The main objective of this work is to evaluate the impact of the incorporation of Clinicgram, a mobile App and a Cloud platform with Artificial Intelligence algorithms to help the clinician as a decision support system to assess and evaluate correct treatments. Second objective evaluates how the professional can benefit from this technology into the real clinical practice, how it impacts patient care and how the organisation’s resources can be optimised. METHODS Clinicgram application and framework is a non-radiological clinical imaging management tool that is incorporated into clinical practice. The tool will also enable the execution of the different algorithms intended for assessment in this study. With the use of computer vision and supervised learning techniques, different algorithms are implemented to simplify a practitioner's task of assessment and anomaly spotting in clinical cases. Determining the area of interest of the case automatically and using it to assess different wound characteristics such as area calculation and tissue classification, and detecting different signs of infection. An observational and an objective study have been carried out that will allow obtaining clear indicators of the level of usability in clinical practice. RESULTS A total of 2,750 wound pictures were taken by 10 nurses for analysis during the study from January 2018 to November 2021. Objective results have been obtained from the use and management of the application, important feedback from professionals with a score of 5.55 out of 7 according to the mHealth App Usability Questionnaire. It has also been possible to collect the most present type of wound according to Resvech 2.0 of between 6 and 16 points of severity, and highlight the collection of images of between 0 and 16 cm2 of area 88%, with involvement of subcutaneous tissue 53.21%, with the presence of granulated tissue 59.16% and necrotic 30.29% and with a wet wound bed 61.54%. The usage of app to upload samples increase from 31 to 110 samples per month from 2018 to 2021. CONCLUSIONS Our real-world assessment demonstrates the effectiveness and reliability of the wound assessment system, increasing professional efficiency, reducing data collection time during the visit and optimising costs-effectivity in the healthcare organisation by reducing treatment variability. Also, the comfort of the professional and patient. Incorporating a tool such as Clinicgram into the chronic wound assessment and monitoring process adds value, reduction of errors and improves both the clinical practice process time, while also improving decision-making by the professional and consequently having a positive impact on the patient's wound healing process.

Abstract Background Artificial intelligence (AI) research in healthcare is accelerating rapidly, with potential applications being demonstrated across various domains of medicine. However, there are currently limited examples of such techniques being successfully deployed into clinical practice. This article explores the main challenges and limitations of AI in healthcare, and considers the steps required to translate these potentially transformative technologies from research to clinical practice. Main body Key challenges for the translation of AI systems in healthcare include those intrinsic to the science of machine learning, logistical difficulties in implementation, and consideration of the barriers to adoption as well as of the necessary sociocultural or pathway changes. Robust peer-reviewed clinical evaluation as part of randomised controlled trials should be viewed as the gold standard for evidence generation, but conducting these in practice may not always be appropriate or feasible. Performance metrics should aim to capture real clinical applicability and be understandable to intended users. Regulation that balances the pace of innovation with the potential for harm, alongside thoughtful post-market surveillance, is required to ensure that patients are not exposed to dangerous interventions nor deprived of access to beneficial innovations. Mechanisms to enable direct comparisons of AI systems must be developed, including the use of independent, local and representative test sets. Developers of AI algorithms must be vigilant to potential dangers, including dataset shift, accidental fitting of confounders, unintended discriminatory bias, the challenges of generalisation to new populations, and the unintended negative consequences of new algorithms on health outcomes. Conclusion The safe and timely translation of AI research into clinically validated and appropriately regulated systems that can benefit everyone is challenging. Robust clinical evaluation, using metrics that are intuitive to clinicians and ideally go beyond measures of technical accuracy to include quality of care and patient outcomes, is essential. Further work is required (1) to identify themes of algorithmic bias and unfairness while developing mitigations to address these, (2) to reduce brittleness and improve generalisability, and (3) to develop methods for improved interpretability of machine learning predictions. If these goals can be achieved, the benefits for patients are likely to be transformational.

ObjectiveTo summarise the literature on the assessment of competences in postgraduate medical training.MethodsA systematic literature review was performed within a EULAR taskforce on the assessment of competences in rheumatology training and other related specialities (July 2019). Two searches were performed: one search for rheumatology and one for related medical specialities. Two reviewers independently identified eligible studies and extracted data on assessment methods. Risk of bias was assessed using the medical education research study quality instrument.ResultsOf 7335 articles in rheumatology and 2324 reviews in other specialities, 5 and 31 original studies were included, respectively. Studies in rheumatology were at variable risk of bias and explored only direct observation of practical skills (DOPS) and objective structured clinical examinations (OSCEs). OSCEs, including clinical, laboratory and imaging stations, performed best, with a good to very good internal consistency (Cronbach’s α=0.83–0.92), and intrarater reliability (r=0.80–0.95). OSCEs moderately correlated with other assessment tools: r=0.48 vs rating by programme directors; r=0.2–0.44 vs multiple-choice questionnaires; r=0.48 vs DOPS. In other specialities, OSCEs on clinical skills had a good to very good inter-rater reliability and OSCEs on communication skills demonstrated a good to very good internal consistency. Multisource feedback and the mini-clinical evaluation exercise showed good feasibility and internal consistency (reliability), but other data on validity and reliability were conflicting.ConclusionDespite consistent data on competence assessment in other specialities, evidence in rheumatology is scarce and conflicting. Overall, OSCEs seem an appropriate tool to assess the competence of clinical skills and correlate well with other assessment strategies. DOPS, multisource feedback and the mini-clinical evaluation exercise are feasible alternatives.

Community nurses regularly treat patients with chronic wounds (those persisting over 6 weeks); with the complexity of both the patients' health needs and the wound itself, this often becomes a highly time-consuming task for the nurse. Wound assessment tools are designed to support all qualified nurses, regardless of whether the nurse possesses specialist wound care knowledge or not, in delivering safe and appropriate wound care. The wound assessment tool, using the acronym TIME, has been recently amended to now be known as TIMERS (Tissue, Infection/Inflammation, Moisture, Wound edge, Repair/Regeneration, Social). This article will examine what the newly amended wound assessment tool TIMERS represents, in addition to looking at the practical issues around its implementation in community settings.

Objective: Telemedicine is an essential support system for clinical settings outside the hospital. Recently, the importance of the model for assessment of telemedicine (MAST) has been emphasised. The development of an eHealth-supported wound assessment system using artificial intelligence is awaited. This study explored whether or not wound segmentation of a diabetic foot ulcer (DFU) and a venous leg ulcer (VLU) by a convolutional neural network (CNN) was possible after being educated using sacral pressure ulcer (PU) data sets, and which CNN architecture was superior at segmentation. Methods: CNNs with different algorithms and architectures were prepared. The four architectures were SegNet, LinkNet, U-Net and U-Net with the VGG16 Encoder Pre-Trained on ImageNet (Unet_VGG16). Each CNN learned the supervised data of sacral pressure ulcers (PUs). Results: Among the four architectures, the best results were obtained with U-Net. U-Net demonstrated the second-highest accuracy in terms of the area under the curve (0.997) and a high specificity (0.943) and sensitivity (0.993), with the highest values obtained with Unet_VGG16. U-Net was also considered to be the most practical architecture and superior to the others in that the segmentation speed was faster than that of Unet_VGG16. Conclusion: The U-Net CNN constructed using appropriately supervised data was capable of segmentation with high accuracy. These findings suggest that eHealth wound assessment using CNNs will be of practical use in the future.

Background and Motivation: Diagnosis of Parkinson’s disease (PD) is often based on medical attention and clinical signs. It is subjective and does not have a good prognosis. Artificial Intelligence (AI) has played a promising role in the diagnosis of PD. However, it introduces bias due to lack of sample size, poor validation, clinical evaluation, and lack of big data configuration. The purpose of this study is to compute the risk of bias (RoB) automatically. Method: The PRISMA search strategy was adopted to select the best 39 AI studies out of 85 PD studies closely associated with early diagnosis PD. The studies were used to compute 30 AI attributes (based on 6 AI clusters), using AP(ai)Bias 1.0 (AtheroPointTM, Roseville, CA, USA), and the mean aggregate score was computed. The studies were ranked and two cutoffs (Moderate-Low (ML) and High-Moderate (MH)) were determined to segregate the studies into three bins: low-, moderate-, and high-bias. Result: The ML and HM cutoffs were 3.50 and 2.33, respectively, which constituted 7, 13, and 6 for low-, moderate-, and high-bias studies. The best and worst architectures were “deep learning with sketches as outcomes” and “machine learning with Electroencephalography,” respectively. We recommend (i) the usage of power analysis in big data framework, (ii) that it must undergo scientific validation using unseen AI models, and (iii) that it should be taken towards clinical evaluation for reliability and stability tests. Conclusion: The AI is a vital component for the diagnosis of early PD and the recommendations must be followed to lower the RoB.
