Outcomes

Primary Outcome Measures

Treatment adherence at 12 weeks
Treatment adherence, defined as the proportion of subjects in both groups that meet a desired adherence rate of > 80%, calculated by pill count adherence rate

Secondary Outcome Measures

Treatment adherence at 6 months
Treatment adherence, defined as the proportion of subjects in both groups that meet a desired adherence rate of > 80%, calculated by pill count adherence rate
Treatment adherence at 12 months
Treatment adherence, defined as the proportion of subjects in both groups that meet a desired adherence rate of > 80%, calculated by pill count adherence rate
Differences in self-reported treatment adherence measured by brief-IPQ
Differences in self-reported treatment adherence measured by brief-IPQ, a 9 item questionnaire where every item is assessed individually (0 to 10 response scale) except for 1 open-ended response item
Differences in self-reported treatment adherence measured by BMQ
Differences in self-reported treatment adherence measured by BMQ, questionnaire with 2 subscales. Necessity subscale ranges from 5-20, where lower scores indicate low necessity beliefs. Concern scale ranges from 5-20 where lower scores indicate higher confidence in positive effects of medication.
Differences in self-reported treatment adherence measured by 8-point MMAS
Differences in self-reported treatment adherence measured by 8-point MMAS. Total scores range between 0 to 8, where a higher score indicates higher treatment adherence
Differences in self-reported treatment adherence measured by MARS questionnaire
Differences in self-reported treatment adherence measured by MARS questionnaire 5. Scores range between 1-25, where a higher score indicates higher reported treatment adherence
Change in clinical symptoms measured by DSQ questionnaire
Change in clinical symptoms measured by DSQ questionnaire. Total score range from 0 to 84, where higher scores indicate more symptoms
Change in clinical symptoms measured by SDI questionnaire
Change in clinical symptoms measured by SDI questionnaire. Total scores of the SDI ranges between 0 to 9, where higher scores indicate more symptoms.

5. Study Description

Brief Summary
In many chronic conditions adherence to long-term treatment is a challenge, also for patients with eosinophilic esophagitis. Interventions, such as behavioral, educational and reminder interventions might improve treatment adherence. With this trial the investigators want to assess the effects of additional education in combination with more frequent follow up and patient reminders on adherence to treatment in adult patients with eosinophilic esophagitis.
