Covid module high risk

Hello, hope you're well!

The first release of the April wave of the Covid module contained derived variables for being at high risk and very high risk to Covid-19. I noticed that these variables are no longer available in the latest version of the dataset (or in other waves). We used the variables in some earlier work on mental health over the crisis (Banks and Xu 2020) which we are looking to extend, and it would be very helpful if we could recreate the variables for the latest data.

Presumably the derived variables were based on baseline hcond - is that right? If so, would you be able to provide a list of the conditions included in the high risk and very high risk categories please?

Thanks so much for your help! It would be brilliant if you could get back to me relatively quickly, as we're looking to submit a draft before Christmas. Thanks very much!

Best wishes,

The derived variable which identified individuals who were considered to be highly or extremely highly clinically vulnerable wrt Covid (NHS definition) has been included in the latest release of the data for all waves (released today). Please note that some changes have been made:
1. cW_vhrisk_dv and cW_hrisk_dv have been combined into one variable as these were designed to be non-overlapping and so more suitable as one variable
2. the variable has been renamed to correctly reflect its purpose: “cW_clinvuln”
3. A note in the User Guide explains the criteria and variables used to create it (see Section 11.7).

In Wave 2 (cb_, May), the question module about treatments (cW_hcond_treat) were not asked of returning respondents, and in Wave 3 (cc_, June) these were not asked of returning respondents who didn’t report a new health condition (cW_hcondnew_cv) and so these variables were withdrawn while this issue was investigated. We have concluded that while it did impact on identification of the extremely vulnerable people (6.2% in Wave 1, 2% in Wave 2, 4% in Wave 3, 6% in Wave 4), it would still be useful for data users and so we have released these variables with this disclaimer.

Hope this helps. If you have further questions please let us know.
