Objectives:
Drug-food interactions (DFIs) are a problem in clinical practice as they can alter the bioavailability of drugs and nutrients and may lead to various adverse effects. Healthcare professionals (HCPs) play a significant role in counselling patients and preventing these interactions. Knowledge, attitudes and practices (KAPs) regarding DFIs are, therefore, vital to ensure that they carry out their role efficiently. This review maps evidence on KAPs of HCPs regarding DFIs and highlights gaps for further research.
Methods:
A systematic literature search for the period from 1990 to 2018 was done using Google Scholar, PubMed and ScienceDirect. Keywords such as 'knowledge, attitudes, practices, healthcare professionals, drug-food interactions' in combination with the Boolean operator (AND) were used. Articles published only in English that described KAPs of HCPs relating to DFIs were included.
Key Findings:
Twelve studies were included in this review. Inadequate knowledge was observed among the HCPs as they were unable to identify important DFIs. The HCPs had a positive attitude towards acquiring knowledge, reporting and counselling patients on DFIs. Most of the medical residents felt that they were inadequately trained on DFIs and over half believed that DFIs were only slightly important in clinical practice.
Conclusion:
Deficits exist in the KAPs of HCPs regarding DFIs. An educational intervention targeting HCPs is recommended. Further research assessing the KAPs of the HCPs is required as the small number of studies conducted was a limitation.

Pharmacovigilance
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
