Joint British Societies risk chart (JBS3)

Background info: JBS2

JBS3 is an update of JBS2 published by the Joint British Societies.

A unique aspect of JBS3 is the emphasis upon the lifetime risk of CVD events while previously, all the risk scales developed were used to predict risk of CVD events within a specific time frame (e.g. 10-year risk).

1) End-points measured

Both 10-year risk and lifetime risk of CVD
- CVD includes: coronary heart disease (angina and myocardial infarction), stroke, transient ischaemic attacks, but not peripheral vascular disease

2) Profile of original population at baseline

Based on QRISK Lifetime (1)
- QResearch database: all participating practices in England and Wales
- Age: 30 to 84
- Exclude patients who did not have a postcode related Townsend deprivation score, those who had been prescribed statins before the study start date and those with pre-existing cardiovascular disease
- Participant number: 1,267,159

3) Validation

No validation studies found

4) Length of follow up

QRISK Lifetime: up to 16 years

5) Risk factors involved

Non modifiable risk factors
- Gender
- Age
- Ethnicity
- Family history of CVD
- Townsend quintile
Modifiable risk factors
- Smoking status
- Lipid profile (Total cholesterol and HDL cholesterol)
- Systolic blood pressure
- Diabetes

6) Future work

No future work has been noted from the authors.
