Multistep instructions per instruction line, using abbreviations and medical jargon seem to hinder the correct interpretation of DLIs. We found that textual elements contributing to the correct interpretation of DLIs were: Using explicit time periods in dosage instructions, using plain language, presenting numbers in a numerical format, and providing DLIs in patients' native language. Results A total of 434 studies were identified of which 28 studies met our inclusion criteria. Method A systematic search was performed in PubMed, EMBASE, PsychINFO, and Smartcat (until April 2019) to identify studies investigating textual elements that facilitate or hinder the correct interpretation of DLIs in relation to patients' health literacy.
Textual elements how to#
In order to provide concrete directions for health professionals on how to optimize drug prescriptions, we performed a systematic review to summarize the available research findings on which textual elements facilitate or hinder the correct interpretation of DLIs in relation to patients' health literacy. What is yet unknown, is how specific textual elements in DLIs (e.g., the presentation of numbers, or use of medical jargon) and patients' health literacy skills are related to the comprehension of DLIs. DLIs are often too difficult for patients, especially for those with limited health literacy. Introduction Correct interpretation of drug labels instructions (DLIs) is needed for safe use and better adherence to prescribed drugs.
