Plain English Summary

Background and study aims
COVID-19 is a condition caused by the coronavirus (called SARS-CoV-2) that was first identified in late 2019. This virus can infect the respiratory (breathing) system. Some people do not have symptoms but can carry the virus and pass it on to others. People who have developed the condition may develop a fever and/or a continuous cough among other symptoms. This can develop into pneumonia. Pneumonia is a chest infection where the small air pockets of the lungs, called alveoli, fill with liquid and make it more difficult to breathe.

In 2020, the virus has spread to many countries around the world and neither a vaccine against the virus or specific treatment for COVID-19 has yet been developed. As of March 2020, it is advised that people minimize travel and social contact, and regularly wash their hands to reduce the spread of the virus.

Groups who are at a higher risk from infection with the virus, and therefore of developing COVID-19, include people aged over 70 years, people who have long-term health conditions (such as asthma or diabetes), people who have a weakened immune system and people who are pregnant. People in these groups, and people who might come into contact with them, can reduce this risk by following the up-to-date advice to reduce the spread of the virus.

There is very little known amount the risk factors among those with diabetes that contribute to risk of COVID-19. This study aims to understand the risks of and risk factors for COVID-19 in people with diabetes

Who can participate?
People living with or without diabetes in Scotland with COVID-19

What does the study involve?
Health records of people with COVID-19 will be compared to records of people with and without diabetes to find risk factors that contribute to death with COVID-19 in diabetes patients.

What are the possible benefits and risks of participating?
None

Where is the study run from?
Public Health Scotland (UK)

When is the study starting and how long is it expected to run for?
April 2020 to July 2020

Who is funding the study?
Public Health Scotland (UK)

Risk of and risk factors for fatal or critical care unit treated COVID-19 and development of a risk prediction model in people with diabetes in Scotland: A cohort study

Acronym

Study hypothesis

Objectives:
1. Ascertain the cumulative risk of fatal or CCU treated COVID -19 in those with diabetes and compare it to those without diabetes
2. Among those with diabetes to investigate risk factors for, and build a cross-validated predictive model of, fatal or CCU treated COVID-19

Condition

COVID-19 (SARS-CoV-2 infection), diabetes

Intervention

In the total population of Scotland (5.6 million) we will ascertain all persons who had developed fatal or critical care unit-treated COVID-19 (hereafter F/CCU-COVID-19) between 1st March and July 31st 2020 from the nationwide virology, critical care unit, hospital discharge and register of deaths databases. Among those with F/CCU-COVID-19, diabetes status will be ascertained by linkage to the national diabetes register. The cumulative incidence of F/CCU-COVID-19 in those with and without diabetes will be compared using logistic regression. Among those with diabetes, data on potential risk factors for F/CCU-COVID-19 will be obtained from diabetes register and other linked health administrative databases. Among those with diabetes we will test association of these factors with F/CCU-COVID-19 and construct a prediction model using stepwise regression and 20-fold cross-validation.
