The ABC taxonomy for medication adherence translated into French and German

Abstract

Aims We translated the ABC adherence taxonomy (i.e. 7 terms and their corresponding definitions) published by Vrijens et al. (2012) into French and German without changing the original meaning with the aim to promote a standardised taxonomy for medication adherence to French‐ and German‐speaking researchers and clinicians. Methods A Delphi survey was performed. To generate round 1, we identified French and German synonyms for the 7 adherence terms through a literature search in PubMed. Investigators translated the original English definitions into French and German. Panellists were members of ESPACOMP—the International Society for Patient Medication Adherence; experts suggested by ESPACOMP members and first authors of medication adherence publications in French and German. Google forms were used to create online questionnaires. Delphi rounds were performed until consensus was reached. The consensus was defined according to the acceptance rate as moderate consensus (50–75%), consensus (>75–95%), and strong consensus (>95%). Results The literature search resulted in 4–6 (French) and 4–7 (German) items per English term. Delphi rounds were launched between November 2016 and April 2018. Three rounds sufficed to reach consensus on all terms and definitions from 26 French‐speaking and 25 German‐speaking panellists. Preferred terms for medication adherence are adhésion médicamenteuse (82%) in French and Medikamentenadhärenz (88%) in German. Conclusion The use of a common terminology for medication adherence with translations in French and German will contribute to standardise the vocabulary, to harmonise research projects and ultimately ease comparison of study results among researchers and clinicians.

“… 141 , 142 Medication adherence is multifaceted and composed of 3 distinct phases: 1) initiation, which is when a patient takes the first dose of a prescribed medication; 2) implementation, the extent to which a patient’s actual dosing corresponds with the prescribed regimen from initiation until the last dose; and 3) persistence, which is the time period between initiation and when a patient stops taking a prescribed medication (discontinuation). 143 , 144 , 145 , 146 , 147 Each of these phases warrants specific attention and support to ensure optimal benefit from the prescribed medication ( Table 2 ).…”

Italian Translation and Validation of the Original ABC Taxonomy for Medication Adherence

“…Thanks to the growing interest in the ABC Taxonomy in scientific research and to its implications for improving medication adherence in daily practice, the ABC Taxonomy may be considered a promising and useful model to conceptualize and study medication adherence [ 22 , 23 ]. The Taxonomy was first published in English and subsequently translated into French and German with the aim of harmonizing terminology across languages and further increasing comparability in scientific research [ 24 ]. Thus, it is necessary to increase the number of languages in which to standardize and validate the terminology related to medication adherence, with the ultimate goal of eradicating ambiguity in adherence research.…”

Delta T, a Useful Indicator for Pharmacy Dispensing Data to Monitor Medication Adherence

“…Further, an aggregate estimate obscures the variability of refills over time i.e., the dynamic of medication adherence. Such inaccuracy deviates from consensus-based guidelines' advice on best practice in defining medication adherence (ABC-Taxonomy) [14,15] or reporting of empirical studies (EMERGE-guidelines) [16]. According to these new recommendations, medication adherence research should specify the medication adherence phases under scrutiny, that is, initiation, implementation, or discontinuation.…”
