Objective: The study aimed to prepare, validate, and test the reliability of the Medication Knowledge Assessment Questionnaire and assess the patients’ knowledge about their medications.

Methods: The Medication Knowledge Assessment Questionnaire was prepared subsequently, referring to primary, secondary, and tertiary resources. An expert panel validated the content of the Medication Knowledge Assessment Questionnaire. The validated Medication Knowledge Assessment Questionnaire was translated into Kannada and Malayalam languages. The test–retest reliability was conducted on day 1 and after a week among 15 patients. During the interview, the patients’ medication knowledge was assessed based on 10 parameters: name, indication, dose, time and frequency of administration, storage, refilling, pre- and post-prandial directions, side effects, and missed dose.

Results: The Cronbach’s alpha reliability values of the Medication Knowledge Assessment Questionnaire were in the range of 0.716-1.00, which shows that the Medication Knowledge Assessment Questionnaire is reliable for evaluating the medication knowledge among hemodialysis patients. Patients had comparatively very low-level knowledge about the side effects and actions to be taken if a dose is missed among the knowledge parameters surveyed. The average number of medications prescribed per patient was 7.65.

Conclusions: In the present study, the maximum medication knowledge scores have been accounted for drug administration sequence with respect to food (95.39) and storage of medications (95.27). The Medication Knowledge Assessment Questionnaire is a vital tool for assessing patients’ medication knowledge and improving patients’ therapeutic outcomes.
