The outcome measure was the odds of patients having received health messages in the period before they contacted their GP, compared to the odds in the control periods.Setting The practices of 21 single-handed Danish GPs.Method Three hundred and twenty-two patients between 18 and 91 years of age were interviewed by telephone after an unscheduled contact with a GP, and 148 patients were interviewed again 3–6 months later. Health media messages were only recorded if patients could remember the topics.Result More than a third (35%) of the patients remembered receiving health media messages in the week before contact. No significant relationship (odds ratio = 1.2, 95% confidence interval = 0.5 to 2.6) between health messages and contact with GPs could be observed.Conclusion In the absence of health campaigns and drug advertisements, mass media health messages seldom directly trigger patients to consult their GPs.
