Prevention – differentiating primary and secondary
Advice on research activities
The 3 Prevention code group should be used for primary prevention studies only and not for secondary prevention.
e.g. anti-smoking education in adolescence should be coded as 3.1 Primary prevention.
Prevention of the re-occurrence of a condition or prevention of a closely related condition arising from the pre-existing disease (secondary prevention) should not be coded within the 3 Prevention code group.
Prevention of a disease or condition within a specific patient group where the preventable disease is either unrelated to or may be a future sequela of the patient’s current condition can be coded as primary 3 Prevention.
e.g. prevention of cardiovascular disease in diabetic patients with no current cardiovascular disease diagnosis.
In circumstances where a study is focussed on preventing the side effects of a treatment, it would be appropriate to code to 3 Prevention and code to either 5 Treatment Development or 6 Treatment Evaluation.
