Presentation 1: Geodemographic analysis of the impact of COVID-19 on urgent cancer referrals using local and national data set

By: Ifeanyi Chukwu

Abstract: The COVID-19 pandemic has had a profound effect on the “normal” flow of things everywhere. The impact was even more devastating on urgent cancer referrals early in the periods of the pandemic, with referrals falling by at least 70% at the nadir (Lai, 2020). This study will first utilise the urgent cancer referrals data set from the Leeds Teaching Hospital NHS Trust, to develop a model that will be applied to the England urgent cancer referrals dataset.

This project aims to investigate the geodemographic attributes of patients most affected by the drop in the urgent cancer referrals pathway during the pandemic. This will be useful in making inferences of the social groups most impacted by the drop in urgent cancer referrals. This will inform optimum resource redistribution as society recovers from the pandemic. Therefore, this study has three aims: one; to explore the geographical dimensions of the impacts of the decline in urgent cancer referrals, e.g., the influences that the proximity to healthcare facilities and transport systems etc., have on the urgent cancer referrals. Two; to explore the demographics of patients affected, in terms of age band, sex, ethnicity etc. Three; to investigate how patients with different geodemographic backgrounds i.e., index of deprivation, and Acorn, fared.

By utilizing the geodemographic classifications of the UK population in a clinical study, this study will suggest a move away from the traditional homogenous view of patients to one that utilises the heterogeneous geodemographic classifications of patients.

Presentation 2: Evaluating strategies to promote healthier and more sustainable dietary choices

By: Ann Onuselogu

Abstract: What we eat not only affects our bodies but the Earth too. It is well recognised that a shift is needed towards healthier and more sustainable dietary choices. The Institute of Grocery Distribution (IGD) is working with the University of Leeds, retailers and manufacturers to initiate this change, with the aim of making healthy and sustainable diets easy and accessible for all. The U.K. government’s EatWell Guide provides dietary recommendations which are beneficial to both individual health and the health of the planet.  

A series of interventions are being trialled by members of the IGD’s Healthy and Sustainable diets project group, to identify how retailers and manufacturers can encourage consumers towards healthier and more sustainable dietary choices in line with the EatWell guide. Different behavioural levers will be investigated across interventions conducted by multiple retailers. 

This project will evaluate the strategies implemented by these interventions, using a range of statistical and visualisation methods. Through analysing consumer data, we aim to determine which levers are particularly successful for driving positive, long-term behavioural change.  

Presentation 3: CosMoNorth: Comprehensive Spatial Modelling for the North

By: Indumini Ranatunga

Abstract: For active urban analytics work carried out at LIDA, it is becoming more evident than ever that a consolidated modelling framework for spatial simulation is a necessity. Many researchers and PhD students usually have no choice but to start from the ground up construction of a baseline travel model to address their advanced research questions. While an established spatial simulation model at the very least can be used as a teaching tool in for e.g., M.Sc. programs, it could also a) speed up development of new models under tested assumptions and limitations b) provide a calibrated platform for model validation and docking, and c) improve routes to impact. Simulation data and generation of scenarios from this baseline model can furthermore aid in responding to emerging policies, testing new protocols in case of future emergencies, contributing to current policy debate, both in the public discourse and in direct collaboration with policymakers and thereby influence local government decisions.

For the purpose of meeting the above expectations, the CosMoNorth project was introduced with the goal of building a new calibrated agent based simulation using the MATSIM framework of mobility and activity of the Northern Powerhouse region. Funded by the CDRC, this project is supported with tools and expertise by City Modelling Lab at Arup and resourced from data sources such as i.e. NTS data, SPENCER modelling platform etc.

This talk will mainly discuss more in detail about the project, the current work carried out so far and next steps in model development.
