My thanks to Dr David Fitzsimons who has pointed out that it is not only depression that has suffered a ruleset that differs from the guidance. PP1 - the assessment of CVD risk in patients newly diagnosed with high blood pressure - features an almost identical change. Whilst the guidance suggests only the patients diagnosed in the past year should be counted the business rules carry forward all of the unassessed patients from the previous year. There is not a lot that a practice can do to avoid this, unless of course their hypertension has resolve (read code 212K ) in the meantime.
