Base Hospitalisation Risk & Vaccination

Lessons from an undisclosed NHS Trust

Following on from my work on base hospitalisation risk for reports 19 and 20 I thought I’d bake this rather tasty slide this misty morning. Just to recap that base hospitalisation risk is derived from a consideration of hospitalisation rates for 884 different diagnoses and 77 procedures undertaken within the emergency department. These rates are combined on a case-by-case basis to form a mean risk score.

If we take adult (+18y) non-COVID admissions and break vaccination status down into never vaccinated, admitted after the first dose but with no further vaccination and admitted after multiple doses (second dose and/or booster) we get this interesting chart. We can clearly see that those who opt for multiple vaccinations possess the lowest mean hospitalisation scores in each and every age band.
