Adherence in Global Airways

Summary

There is a strong case for treating diseases of both the upper and lower airways (global airways) simultaneously because they share the same inflammatory mechanisms. About 9% have chronic sinusitis (CRS) and 4% of the Danish population are diagnosed with CRS with nasal polyps (CRSwNP)) and 7-10% have asthma. CRS has a multifactorial background, with CRSwNP characterized by Type 2 inflammation, and approximately 50% with Type 2 CRSwNP also have co-morbid asthma. Well-treated CRS has an impact on asthma control, and well-treated asthma has an impact on CRS.

Several studies show that patients with asthma have low adherence, but only a few if any of studies are available on adherence in CRS.

Aim:

To investigate the effect of systematic and structured nursing supervision in patients with CRSwNP and asthma primarily on adherence.

Hypothesis and research questions: Patients with respiratory diseases can improve their adherence to their non-medical and medical treatment for CRSwNP/CRS and asthma by systematic and structured nursing supervision compared to patients who receive usual care.

In a randomized clinical trial, we will investigate whether the level of adherence measured by the questionnaire MARS-5-N and MARS-5- L in patients with CRSwNP and asthma can be improved by 7 points after systematic and structured nursing guidance at baseline visit and controlled after four months - compared with those patients who have not received the above guidance.

Primary outcome: is change in adherence rate measured by the MARS-5-N/L questionnaire in patients with CRSwNP and asthma can be improved by 4 points after systematic and structured nursing guidance at the initial visit and controlled after four months - compared with patients who have not received the above guidance.

Inclusion Criteria:

Adherence to MARS- 5 L/N ≤35 at first visit, diagnosed with asthma (with/without allergic rhinitis) at initial visit, diagnosed with CRSwNP, able to use smartphone, ACQ ≥1.2 or ACT≤15 (partially uncontrolled asthma), \>18 years of age, SNOT-22 score ≥35

Exclusion Criteria:

* Adherence to MARS-5- L/N \>35 points at first visit,do not have smartphone, does not read/speak English, other illness requiring regular medication, pregnancy/pregnancy that started during the study, server psychological comorbidities

Questionnaires: Patients must answer the following questionnaires at baseline and at 4 months follow up ESS, SNOT-22, ACQ-7, ACT, MiniAqLq, HADS, STARR-15

Conditions

• Chronic Rhinosinusitis Without Nasal Polyps
• Asthma
• Chronic Rhinosinusitis With Nasal Polyps
• Chronic Rhinosinusitis (Diagnosis)

Interventions

BEHAVIORAL

Controlgroup

The control group and intervention group will receive daily text message reminders twice a week to take their medications and to rinse their nose.

BEHAVIORAL

Intervention

Patients in the intervention group will receive systematic and structured nursing guidance regarding their adherence, which includes proper use of nasal irrigation once or twice daily, nasal steroid/drops, use of inhaled medications, follow-up of smoking status. The intervention group will receive guidance videos which have been prepared prior to the study and will be standard for the intervention group. Guidance videos will cover the correct use of nasal irrigation, inhalation steroid, and nasal steroid/drops.
