PC-COS survey: Steps
As a reminder, please find a short outline of the process and the two surveys purpose below:

Step 1 – Survey 1 (20-30 minutes to complete):

In the first survey, you will view a list of outcomes. For each outcome, you will rate how important you think it is to measure that outcome for all future research and clinical care of long COVID. At the end of the survey, you can also suggest any other important outcomes are missing from the list. You can add comments to explain your decisions.


Once the deadline for completing the survey has passed, we will analyse everyone’s responses. We will then email you instructions on how to take part in the second survey.

Step 2 – Survey 2 (5-10 minutes to complete):

In the second survey, you will see the same list of outcomes (apart from those reaching an a priori criteria for consensus) from survey 1 with a reminder of your own rating. This time, you will also see a chart that shows how groups of people who took the first survey rated each outcome.


Now, when you rate the outcome, please think about how you and the other groups rated each outcome. This is a chance for you to consider the opinions of others and to reflect on your own previous ratings. We are trying to find out which outcomes people with lived experience, health professionals, researchers and others agree must always be measured.

We are inviting the following groups* to take part:
