Nonadherence and noncompliance was common
Fewer U.K. patients (32%) reported taking their preventive therapy as advised, compared with German patients (60%) and U.S. patients (80%). Common reasons for noncompliance, regardless of location, were forgetfulness, the belief that a dose was not needed, and side effects. Most patients in the United Kingdom (60%) and the United States (54%) reported the need to take an extra dose of their acute medication to relieve pain symptoms, compared with 30% in Germany. Furthermore, 13% of U.S. patients indicated that they took extra doses all the time or nearly all the time, compared with 2% in Germany and 7% in the United Kingdom. Among patients who had discontinued a preventive treatment in the past, the most common reasons for discontinuation were lack of efficacy and problems with tolerability.
One limitation of the study was that the survey was not designed to represent the general cluster headache or treating physician populations fully. The data may reflect selection bias in favor of physicians who treat high volumes of patients and in favor of patients who frequently seek health care. In addition, the data were based on self-reports.
“Increased awareness and educational efforts that aim at promoting the need and benefit of the preventive treatment for these patients is warranted,” Dr. Andrews concluded.
