Clinical Trial Summary

Based on barriers identified in a systematic literature search, a self-report questionnaire called "BIOTICA" has been developed by the research team to assess medication adherence barriers to oral AB. The purpose of the BIOTICA-questionnaire is to detect individual barriers that prevent the optimal intake of oral AB and thus, lead to inadequate adherence or persistence to the regimen. A study is now needed to establish construct validity. Correlation between the answers to the BIOTICA-questionnaire and the electronically monitored intake of the oral AB will be analyzed in the general population.

Description:

Global consumption of oral antibiotics (AB) is increasing, with 80% of all prescriptions in Europe stemming from primary care, mostly against respiratory tract infections. Adequate intake behavior (i.e. adherence) to oral AB is vital to prevent therapeutic failure, to reduce the risk of microbial resistance, to reduce health care consumption, medication waste and environmental pollution. However, non-adherence among oral AB users reaches rates of 21%-38% during an AB treatment course. To improve medication adherence, understanding patient barriers to treatment is crucial. Based on barriers identified in a systematic literature search, a self-report questionnaire called "BIOTICA" has been developed by the research team to assess medication adherence barriers to oral AB. The purpose of the BIOTICA-questionnaire is to detect individual barriers that prevent the optimal intake of oral AB and thus, lead to inadequate adherence or persistence to the regimen. A study is now needed to establish construct validity (also called criterion, convergent or concurrent validity) that is, to generate evidence that the questionnaire measures what it is intended to. Thus, the instrument under investigation (i.e. BIOTICA-questionnaire) will be distributed at the same time as the targeted attribute (i.e. adherence to oral AB) will be electronically monitored in the general population. The correlation between the two measurements will be analyzed.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Adherence [%] to oral antibiotics	The primary endpoint is the adherence [%] to oral antibiotics calculated as correct dosing days from the electronic adherence data	maximum 30 days
Secondary	Persistence [%] to oral antibiotics	The secondary endpoint is persistence [%] to oral antibiotics defined as the time until medication discontinuation and calculated as the percentage of days with at least one intake	maximum 30 days
