Background and study aims
People with diabetes have suffered greater adverse consequences of COVID-19 in the acute phase of infection during the pandemic. Whether they also have increased susceptibility to longer term sequelae is unknown. Such knowledge is critical to public health approaches to management of the pandemic in these populations. We will build on the excellent available surveillance of the population of people with diabetes in Scotland using the existing sci-diabetes platform, used already to accurately detail short-term outcomes.
Current research during the COVID crisis has highlighted that to the end of July, 2,724 people with diabetes had covid-19 (positive test, admission, or death certificate) of whom 988 had unfortunately died. This means more than 1,736 people with diabetes in Scotland may be living with the consequences of Covid-19. Assessment of the long term holistic impact on people with diabetes cannot be approached using routine data collated from electronic health records and so we propose to use the resources of the Scottish Diabetes Research Network (SDRN) to collect information through questionnaires and clinical examination on a range of outcomes in people with diabetes compared to the general population of people with diabetes.
Who can participate?
People aged over 18 resident in Scotland and with prior diagnosis of type 1 or type 2 diabetes
What does the study involve?
All participants will complete 4 questionnaires online. A smaller group of these participants will also be asked for a blood sample and to take some physical tests during a hospital visit, and repeat these measures after one year.
What are the possible benefits and risks of participating?
The study will not benefit you directly, but your participation will help provide important information about the impact of COVID-19 infection on diabetes patients and provide a stronger evidence base to inform national guidance and policy.
A possible benefit to you might be that if you’ve had COVID without realising it, we will be able to inform you of this.
For some, blood sampling may cause momentary discomfort at the site of the blood draw, possible bruising, redness, and swelling around the site, bleeding at the site, feeling of light headedness when the blood is drawn, and rarely, an infection at the site of blood draw.
There are some risks from the walking test such as tripping, falling, exhaustion and fatigue. A research staff member will be present to offer one:one support and the walk test will be carried out in a wide corridor free of trip hazards and obstructions. You will be able to use a walking aid if you routinely use one.
Lung function tests (spirometry) require the use of a mouthpiece connected to the device which poses a risk of infection. To minimise risk, mouthpiece plastic is single use and you’ll be shown how to carry out the test correctly.

| Scientific title | Longer term impact of COVID infection in people with diabetes |
| Study objectives | To understand the proportion of people with diabetes who experience longer term symptoms or illness after covid-19 infection, the nature of these symptoms, and the potential health impact of that. |
| Ethics approval(s) | Approved 19/05/2021, South East Scotland Research Ethics Committee 1(2ndFloor, Waverley Gate, 2-4 Waterloo Place, Edinburgh, EH1 3EG, UK; +44 (0)7814 764 241; Sandra.Wyllie@nhslothian.scot.nhs.uk), ref: 21/SS/0040 |
| Health condition(s) or problem(s) studied | COVID-19 (SARS-CoV-2 infection) in people with diabetes |
| Intervention | Observational study with current health measured by questionnaire, bioimpedance, pulmonary function, grip strength, walking test. 1. Case cohort study - conducted with questionnaire usually online. Time from enrolment to end of this part of study is 1 hour . For the majority of participants this will be their only participation. 2. Case control study - people are recruited from the case cohort study and involves : 2.1. For controls single CRF visit (time 1 hours) - no in person follow up after this 2.2. Cases 2 CRF visits separated by up to 64 weeks later but each visit only 1 hour: total follow up to 64 weeks For all participants we will request permission to connect data to their electronic health record but no other in person follow up |
| Intervention type | Mixed |
| Primary outcome measure(s) |
COVID symptoms measured using Wellcome Trust COVID-19 questionnaire at baseline (all participants) and 1 year (cases only) |
| Key secondary outcome measure(s) |
Measured at baseline (all participants in case cohort study) and 1 year (cases in case cohort study only) |
| Completion date | 31/10/2024 |

| IPD sharing plan | The datasets generated during and/or analysed during the current study will be stored in a non-publically available repository: the ENLIGHTEN database of the University of Glasgow. Data stripped of all personal identifiers will be stored for 10 years and made available to bona fide researchers after the end of the study and study data analysis . Details of this data storage and sharing are transmitted to participants on the PIS for each part of the study. |
