Samenvatting

Het is niet altijd eenvoudig in de spreekkamer te komen tot echte shared decision making. Om hierover een serieus gesprek met de patiënt te kunnen voeren, is een goed begrip van het potentiële effect van een behandeling, maar ook de nadelendie een behandeling kan veroorzaken cruciaal. Effectiviteit van therapie of preventie wordt dikwijls vastgesteld in vergelijkend klinisch onderzoek. Op grond van de resultaten kan de relatieve risicoreductie van een behandeling worden vastgesteld. Om het belang van het effect naar de individuele patiënt te vertalen, is het absolute risico (of de reductie daarvan) of berekening van het number needed to treat (NNT) van belang. In dit hoofdstuk worden factoren besproken die van belang zijn voor de interpretatie van het NNT. Daarnaast wordt ingegaan op het number unsuccessfully treated en number unnecessarily treated (NUT) van een behandeling. Ten slotte worden relevante uitkomstmaten en consequenties van klinisch wetenschappelijk onderzoek voor de praktijk bediscussieerd.
