Publication: Non occurrence probability increase

Non occurrence probability increase.
Tromsø, Norway: 17th Nordic Congress of General Practice; 2011.


This study aimed at determine how general practitioners themselves, who often give advice in preventive medicine, decide when it comes to their own treatment concerning risk for cardiovascular disease, depending on how problems are framed. Design and results Five audiences of general practitioners with personal response keypads answered the same two questions about treatment or not of the risk for cardiovascular death but presented in two different ways, as RRR when nearly 70 % respectively 85 % of the physicians would accept treatment. When presented as the concept of non-occurrence probability increase (NOPI) the figures were reduced to about 20 % and 15 % respectively (p<10-6). Conclusion Different perspectives of treatment effect will alter even a presumably well-informed physicians’ opinion concerning drug treatment. We think it is important to present physicians with tools to communicate with patients about risk and risk factors. NOPI is such a tool. It gives the patient a more realistic view of the risk when to decide to be treated or not and using the concept of non-occurrence probability increase (NOPI) might reduce drug prescriptions.
