Assessment of knowledge of drug-food interactions among healthcare professionals in public sector hospitals in eThekwini, KwaZulu-Natal

ABSTRACT:

Background

Foods and the nutrients they contain can interact with drugs and thereby interfere with their therapeutic safety and efficacy. Adequate knowledge of healthcare professionals (HCPs) about drug-food interactions can help in preventing potential drug-food interactions among patients. This study aimed to assess the knowledge of HCPs about common drug-food interactions.

Methods

A cross-sectional study was carried out among 459 HCPs from three public hospitals in eThekwini district, KwaZulu-Natal between November 2018, and January 2019. Informed consent was obtained from the HCPs, and a structured questionnaire was thereafter administered. Data were analysed using SPSS® version 25. Factors associated with knowledge of the HCPs were determined using logistic regression analysis.

Results

Of the 459 participants, 22.2% (n = 102) were doctors, 11.3% (n = 52) pharmacists, 63.8% (n = 293) nurses and 2.6% (n = 12) dietitians. Most of the HCPs were females 79.7% (n = 366), the mean age of the HCPs was 38.61±0.48. The knowledge score of the HCPs was 22.66±0.25 out of an overall score of 46. The HCPs poorly identified food types that interact with drugs and correct administration time of drugs relative to meals. Being a pharmacist (OR: 14.212, CI: 4.941–40.879, p<0.001), doctor (OR: 5.223, CI: 2.146–12.711, p<0.001), or a dietitian (OR: 5.476, CI: 1.103–27.191, p = 0.038) was associated with higher knowledge of drug-food interactions.

Conclusion

The HCPs in this survey had low drug-food interaction knowledge. These findings suggest the need for additional training and educational courses for the HCPs on drug-food interactions.

Project description:Introduction: Early detection of certain types of cancer significantly increases the likelihood of successful treatment and reduces mortality from these causes. However, the use of screening and the early detection of selected tumors such as colorectal cancer (CRC) are lower than those expected in our country. The objective of this project is to evaluate the effectiveness of a multicomponent strategy that improves the screening and early detection of CRC in the population at risk of Primary Health Care Clinics (PCCs) of the public health system. Population: people leaving in the catchment area of 10 selected primary care clinics from the public health system in the province of Mendoza, Argentina. Design and methods: a Randomized clinical study by clusters. 10 PCCs will be included: 5 will be randomly assigned to receive an intervention to increase the CRC screening rates (improvement cycles) and 5 to the control arm (usual care). 150 participants will be included in each PCCs, in total, 1500 participants. Intervention: An innovative vision is proposed, which combines a participatory and dynamic methodology based on improvement cycles. This approach includes the implementation of participatory learning sessions for health providers, involving the effectors of the design of the intervention. In the intervention branch at least 3 workshops (sessions) will be held with the members of the care system, in order to identify opportunities for improvement oriented to the design and application of an innovative intervention based on best practices. Each one of the sessions will constitute an analysis of the improvement cycle, following the following steps: 1) Selection of participants of the initial workshop; 2) Development of work model based on bibliographic review and initial qualitative phase; 3) Initial workshop with effectors for training in continuous improvement, objectives, interventions and data collection; 4) Learning workshops to discuss results, applicability of interventions and modifications to the work plan; 5) Closing session to evaluate preliminary results and discuss continuity of interventions beyond the project. Outcomes: 1) Percentage of the population at risk that completes the screening; 2) Percentage of the population classified as at habitual risk or increased by risk factors.
