• (5 May 2023) New paper titled Prediction of disease comorbidity using explainable artificial intelligence and machine learning techniques - A systematic review published on International Journal of Medical Informatics
  
  Mohanad M. Alsaleh - a PhD student at UCL - did a great systematic review on explainable AI methods for predicting comorbidity from electronic health records. It finds “(a) The use of explainable artificial intelligence (XAI) can improve predictions of comorbidities by providing a transparent understanding of the reasoning behind predictions and helping healthcare providers make informed decisions. (b) There is a great potential to uncover novel disease associations and better understand the mechanisms of diseases by integrating genetic and electronic health record (EHR) data, leading to improved quality of care and earlier diagnoses. (c) The use of AI in healthcare can improve patient outcomes and reduce healthcare costs by identifying disease risks and making personalised treatment plans.”

• (7 April 2023) New paper - a systematic review on antidepressant and antipsychotic drug prescribing and diabetes outcomes
  
  As part of her PhD research, Charlotte led this systematic review to investigate the association between antidepressant or antipsychotic drug prescribing and type 2 diabetes outcomes. It concludes - Studies of antidepressant and antipsychotic drug prescribing in relation to diabetes outcomes are scarce, with shortcomings and mixed findings. Until further evidence is available, people with diabetes prescribed antidepressants and antipsychotics should receive monitoring and appropriate treatment of risk factors and screening for complications as recommended in general diabetes guidelines.

• (20 March 2023) <h3>Workshop paper on “Ontology-driven Self-supervision for Adverse Childhood Experiences Identification using Social Media Datasets” now published!</h3> Adverse Childhood Experiences (ACEs) are defined as a collection of highly stressful, and potentially traumatic, events or circumstances that occur throughout childhood and/or adolescence. They have been shown to be associated with increased risks of mental health diseases or other abnormal behaviours in later lives. In this paper, Jinge and colleages present an ontology-driven self-supervised approach (derive concept embeddings using an auto-encoder from baseline NLP results) for producing a publicly available resource that would support large-scale machine learning (e.g., training transformer based large language models) on social media corpus. Jinge presented this paper in 2022 summer at the 1st Workshop on Scarce Data in Artificial Intelligence for Healthcare, which was with IJCAI 2022 in Vienna. Check - Paper, Github Repo

• (7 March 2023) npj Digital Medical’s editorial on automating clinical coding echoes our prospective
  
  Recently, npj Digital Medicine’s editor Dr Kvedar and colleagues have published a great editorial on automating clinical coding (link), pointing out the main challenges including technological and implementation levels; clinical documents are redundant and complex, code sets like the ICD-10 are rapidly evolving, training sets are not comprehensive of codes; capturing the logic and rules of coding decisions. Great to see our prospectives on the automated coding research challenges and future directions were echoed in the editorial!

• (21 February 2023) New paper - The impact of inconsistent human annotations on AI driven clinical decision making now published by npj Digital Medicine
  
  Annotation inconsistencies commonly occur when even highly experienced clinical experts annotate the same phenomenon (e.g., medical image, diagnostics, or prognostic status), due to inherent expert bias, judgements, and slips, among other factors. While their existence is relatively well-known, the implications of such inconsistencies are largely understudied in real-world settings.
  
  Aneeta Sylolypavan did her MSc with us addressing this hugely important research question using real-world ICU datasets with annotated data from 11 ICU consultants. The results suggest that (a) there may not always be a “super expert” in acute clinical settings; and (b) standard consensus seeking (such as majority vote) consistently leads to suboptimal models. Further analysis, however, suggests that assessing annotation learnability and using only ‘learnable’ annotated datasets for determining consensus achieves optimal models in most cases.

• (23 January 2023)   KnowLab is funded by NIHR/HDR UK to use health data science + machine learning for addressing the NHS winter pressure - Using rare disease phenotype models to identify people at risk of COVID-19 related adverse outcome KnowLab is proud to be part of 16 projects funded by HDR UK and funded by NIHR which will use data-driven approaches to pin-point pressures in the health care system, understand their causes and develop ways to overcome or avoid them. Particularly, we will use machine learning and rare disease phenotype models to uncover much-needed information on the added risks of severe COVID-19 in people who are clinically more vulnerable and come from disadvantaged socioeconomic backgrounds. This can then inform policy responses to provide better management and treatment for these most vulnerable groups who might have been overlooked. The team are well placed to derive quick actionable findings for the winter pressures as they have been working with CVD-COVID-UK/COVID-IMPACT on rare diseases since October 2021.

• (21 December 2022) Our UK’s clinical NLP landscaping (a survey) paper is now published with npj Digital Medicine
  
  Aiming to survey the landscape of Clinical NLP in the UK, we used a relatively extraordinary approach - start with finding all relevant funded projects and extract their interlinked information. Then, conducted community analysis and literature review. We described WHO (key players of funders, universities, companies, researchers), WHAT (techs, applications, disease areas, clinical questions, datasets), WHERE (the community developments, tech trends & maturity), GAPS (barriers to unleash the full power of NLP in health). While on the community level we focused on the UK, analyses and discussions on the research, tech and developments were beyond the country boundary. In particular, we compared tech, data, regulatory similarities and differences of the US and the UK. This is one of the key outputs of HDR UK funded National Text Analytics Project.

• (22 October 2022) Dr Hang Dong’s great perspective piece on automated coding using NLP and knowledge-driven approaches has now been published on npj Digital Medicine. The work illustrates how NLP and AI can help improve the efficiency of clinical coding in healthcare - i.e., assign ICD/SNOMED codes to hospital visits, which currently is a very inefficient/erroneous process in NHS and, for that matter, in many other health systems across the world.

• (5 October 2022) Study on The Impact of Inconsistent Human Annotations on AI driven Clinical Decision Making.
  
  Annotation inconsistencies commonly occur when even highly experienced clinical experts annotate the same phenomenon (e.g., medical image, diagnostics, or prognostic status), due to inherent expert bias, judgements, and slips, among other factors. While their existence is relatively well-known, the implications of such inconsistencies are largely understudied in real-world settings.

  The manuscript is now under review with npj Digital Medicine and preprint is available at doi:10.21203/rs.3.rs-1937575/v1.

• (18 August 2022) Our systematic review titled “Artificial intelligence models for predicting cardiovascular diseases in people with type 2 diabetes - a systematic review”, led by Minhong Wang, has been accepted by Intelligence-Based Medicine. This study identified and reviewed existing AI models for predicting risk of cardiovascular diseases in people with type 2 diabetes. We found that compared to risk scores developed using conventional methods, AI approaches have the potential to achieve more accurate predictions than risk scores developed using conventional methods. However, none of the reviewed models is directly reusable or reproducible, due to incomplete reporting and lack of transparency. Clinically, none of the AI models includes interventions that may affect risks such as medications and lifestyle changes. There were no indications in the studies on whether the prediction models might be able to adapt to include these factors.

• (29 July 2022) Our collaboration study titled “Prediction of Five-Year Cardiovascular Disease Risk in People with Type 2 Diabetes Mellitus - Derivation in Nanjing, China and External Validation in Scotland, UK”, led by Cheng Wan from Nanjing Medical University, has been published by Global Heart. This study shows it is feasible to generate a risk prediction model using routinely collected Chinese hospital data. This indicates there is a great potential to make use of the large-scale and relatively easy accessible route data for identifying those at risk of CVD and help significantly improve CVD prevention in people with diabetes.

• (11 July 2022) Our health inequality studies - one led by Isabel Straw and one with Minhong, Aneeta and Prof Sarah Wild (University of Edinburgh) - are featured in a science piece on i news.

• (16 June 2022) Our collaboration study titled “Spine-GFlow - A Hybrid Learning Framework for Robust Multi-tissue Segmentation in Lumbar MRI without Manual Annotation”, led by Dr Teng Zhang from Hong Kong University, has been accepted by Computerized Medical Imaging and Graphics. Results of this study show that our method, without requiring manual annotation, has achieved a segmentation performance comparable to a model trained with full supervision (mean Dice 0.914 vs 0.916).

• (10 June 2022) Out work, titled COVID-19 trajectories among 57 million adults in England - a cohort study using electronic health records, is now out with Lancet Digital Health. Our analyses illustrate the wide spectrum of disease trajectories as shown by differences in incidence, survival, and clinical pathways. We have provided a modular analytical framework that can be used to monitor the impact of the pandemic and generate evidence of clinical and policy relevance using multiple EHR sources.

• (2 May 2022) Our work Quantifying Health Inequalities Induced by Data and AI Models has been accepted by IJCAI-ECAI2022 ‘AI for Good track’. This work introduced a generic allocation-deterioration framework for detecting and quantifying AI induced inequality. Extensive experiments were carried out to quantify health inequalities (a) embedded in two real-world ICU datasets of HiRID and MIMIC III; (b) induced by AI models trained for two resource allocation scenarios. The results showed that compared to men, women had up to 33% poorer deterioration in markers of prognosis when admitted to HiRID ICUs. All four AI models assessed were shown to induce significant inequalities (2.45% to 43.2%) for non-White compared to White patients. The models exacerbated data embedded inequalities significantly in 3 out of 8 assessments, one of which was >9 times worse. preprint, slides, recording, repo.

• (26 April 2022) Study led by Isabel Straw, Investigating for bias in healthcare algorithms - a sex-stratified analysis of supervised machine learning models in liver disease prediction, demonstrates a previously unobserved sex disparity present in published machine learning models. It suggests “To ensure sex-based inequalities do not manifest in medical AI, an evaluation of demographic performance disparities must be integrated into model development.” The work has been published on BMJ Health & Care Informatics.
