Uncertainty-Aware Deep Attention Recurrent Neural Network for Heterogeneous Time Series Imputation

no code implementations4 Jan 2024 Linglong Qian, Zina Ibrahim, Richard Dobson

We propose DEep Attention Recurrent Imputation (DEARI), which jointly estimates missing values and their associated uncertainty in heterogeneous multivariate time series.

Exploring Multimodal Large Language Models for Radiology Report Error-checking

no code implementations20 Dec 2023 Jinge Wu, Yunsoo Kim, Eva C. Keller, Jamie Chow, Adam P. Levine, Nikolas Pontikos, Zina Ibrahim, Paul Taylor, Michelle C. Williams, Honghan Wu

This paper proposes one of the first clinical applications of multimodal large language models (LLMs) as an assistant for radiologists to check errors in their reports.

Discharge Summary Hospital Course Summarisation of In Patient Electronic Health Record Text with Clinical Concept Guided Deep Pre-Trained Transformer Models

1 code implementation14 Nov 2022 Thomas Searle, Zina Ibrahim, James Teo, Richard Dobson

Brief Hospital Course (BHC) summaries are succinct summaries of an entire hospital encounter, embedded within discharge summaries, written by senior clinicians responsible for the overall care of a patient.

Estimating Redundancy in Clinical Text

1 code implementation25 May 2021 Thomas Searle, Zina Ibrahim, James Teo, Richard JB Dobson

This work is a quantitative examination of information redundancy in EHR notes.

Experimental Evaluation and Development of a Silver-Standard for the MIMIC-III Clinical Coding Dataset

1 code implementation WS 2020 Thomas Searle, Zina Ibrahim, Richard JB Dobson

Clinical coding is currently a labour-intensive, error-prone, but critical administrative process whereby hospital patient episodes are manually assigned codes by qualified staff from large, standardised taxonomic hierarchies of codes.

Comparing Natural Language Processing Techniques for Alzheimer's Dementia Prediction in Spontaneous Speech

no code implementations12 Jun 2020 Thomas Searle, Zina Ibrahim, Richard Dobson

We exclusively analyse the supplied textual transcripts of the spontaneous speech dataset, building and comparing performance across numerous models for the classification of AD vs controls and the prediction of Mental Mini State Exam scores.

Identifying physical health comorbidities in a cohort of individuals with severe mental illness: An application of SemEHR

no code implementations7 Feb 2020 Rebecca Bendayan, Honghan Wu, Zeljko Kraljevic, Robert Stewart, Tom Searle, Jaya Chaturvedi, Jayati Das-Munshi, Zina Ibrahim, Aurelie Mascio, Angus Roberts, Daniel Bean, Richard Dobson

Multimorbidity research in mental health services requires data from physical health conditions which is traditionally limited in mental health care electronic health records.

The side effect profile of Clozapine in real world data of three large mental hospitals

no code implementations27 Jan 2020 Ehtesham Iqbal, Risha Govind, Alvin Romero, Olubanke Dzahini, Matthew Broadbent, Robert Stewart, Tanya Smith, Chi-Hun Kim, Nomi Werbeloff, Richard Dobson, Zina Ibrahim

Further, the data was combined from three trusts, and chi-square tests were applied to estimate the average effect of ADRs in each monthly interval.

On Classifying Sepsis Heterogeneity in the ICU: Insight Using Machine Learning

1 code implementation2 Dec 2019 Zina Ibrahim, Honghan Wu, Ahmed Hamoud, Lukas Stappen, Richard Dobson, Andrea Agarossi

Current machine learning models aiming to predict sepsis from Electronic Health Records (EHR) do not account for the heterogeneity of the condition, despite its emerging importance in prognosis and treatment.
