Plain English Summary

Background and study aims
Post COVID-19 condition (PCC), also known as Long Covid, occurs when people continue to experience symptoms for at least two months after the initial COVID-19 infection. These symptoms can affect multiple parts of the body and significantly impact quality of life. Over 200 different symptoms have been reported, including fluctuating health, changes in self-identity, and difficulties accessing healthcare. Many patients feel dismissed by healthcare professionals, which adds to their struggles. New tools like natural language processing and speech-based surveys are being used to better understand the experiences of those living with PCC, aiming to improve patient-centered research and care. The study focuses on identifying key life events and their emotional impact on PCC patients, as well as factors influencing these events and their connection to mental well-being.

Who can participate?
We will invite:
1. Participants from the Zurich SARS-CoV-2 Cohort and Zurich SARS-CoV-2 Vaccine Cohort who reported ongoing symptoms or were diagnosed with PCC.
2. Individuals currently enrolled in the Pycnogenol in Post COVID-19 Condition (PYCNOVID) randomized controlled trial.
3. Individuals considered to have PCC enrolled in a study at the University Hospital Zurich.
4. Individuals with PCC recruited through the ALTEA Long Covid Network and Long COVID Schweiz.

Participants must be adults aged 18 years or older, have good knowledge of German, be able to follow the study procedure, and provide informed consent.

What does the study involve?
Participants will take part in a one-time electronic semi-structured survey. This survey will ask about their experiences living with persistent symptoms, any significant life changes or events since they started experiencing symptoms, and their coping and support strategies.

What are the possible benefits and risks of participating?
The study poses minimal risk to participants. The main risk is the potential for unauthorized access to data, but strict measures are in place to ensure confidentiality and data protection. Participants will not directly benefit from the study, but their contributions will help improve understanding of PCC and guide healthcare professionals, policymakers, and support communities in addressing the needs of those affected. Ultimately, this research could benefit all people living with PCC.

Where is the study run from?
The study is conducted by the Digital & Mobile Health Group at the Institute of Implementation Science in Health Care and the Epidemiology, Biostatistics and Prevention Institute, both at the University of Zurich.

When is the study starting and how long is it expected to run for?
The recruitment period will begin on 25 October 2024 and is expected to end on 28 February 2025. Data collection should be completed by 1 April 2025, with data analyses and final reports expected by 31 January 2026. If the expected sample size is not reached, the study period may be extended with approval from the ethics committee.

Who is funding the study?
The study is funded by the Digital & Mobile Health Group at the Institute of Implementation Science in Health Care and the Epidemiology, Biostatistics and Prevention Institute, both at the University of Zurich.

Scientific titleUnderstanding the experiences of living with Long Covid – the “Living with post COVID-19 symptoms” survey
Study hypothesisThe overall aim of this study is to capture the experience of patients living with post COVID-19 Condition (PCC). The primary objective is to identify categories of life events that patients living with PCC perceive as central. Secondary objectives include evaluating the association of these life events with personal-level characteristics, analyzing how these life events resonated emotionally, identifying personal and professional life changes, and exploring coping and support strategies utilized by participants.

ConditionPersons living with post COVID-19 symptoms
InterventionPeople with protracted symptoms potentially related to PCC and people who have been diagnosed by a healthcare professional with PCC are invited to tell their story about living with persistent symptoms through a one-time electronic semi-structured survey that includes questions on any perceived life changes and major events or experiences since they started experiencing persistent symptoms, as well as coping and support strategies.
Intervention typeNot Specified
Primary outcome measureCategories of key events (e.g., an event marking a loss of one's usual ability to perform, relationship problems resulting from change in health) that participants have experienced and their emotional valence measured using a one-time electronic semi-structured survey
Secondary outcome measuresMeasured using a one-time electronic semi-structured survey:
1. Factors (e.g., age, gender, PCC severity or symptom clusters) associated with experiencing key life event categories
2. Mental wellbeing and depressive symptoms associated with the different life events categories
3. Frequency of high-impact life event types (e.g., personal life, work-related etc.)
4. Coping strategies and experienced support
