Abstract
Using medicines associated with adverse drug reactions (ADRs) might cause serious health complications. The pharmacist plays a unique role in monitoring ADRs, either by themselves or with the assistance of other health-care professionals, to diminish the hazards of ADRs by distinguishing, reporting, and evaluating any proposed ADRs. To train future pharmacists who have adequate knowledge of ADRs and related aspects, it is highly recommended to introduce the WHO-ISoP pharmacovigilance (PV) in the core curriculum. In this article, we shared the suggested curriculum in Aden University. It is based on comprehensive outlines and reference books that offer a broad view of all aspects related to PV. A brief student course evaluation was carried out. Fifty students participated in the survey. Students expressed the importance of the course and indicated that they wanted to know more about the types of ADRs and common medication errors. Some of them lacked an understanding of the causal relationship between ADRs and risk assessment and not familiar with the reporting forms. They suggested for PV awareness programs for health-care staff and public. The curriculum should be tailored according to the country's needs because each country has its own medication safety issues and PV program. To reach the ultimate objective, this article reports the initiative to develop PV proficiencies in a university setting.

Introduction 
Most individuals are exposed to many diseases that necessitate the use of some medicines to treat them. However, using medicine associated with adverse drug reactions (ADRs) might cause serious health complications. According to a few studies, almost 5% of all acute hospitalizations are due to ADRs.[1],[2],[3] The rate of hospitalization could be reduced with ADR monitoring, the realization of the seriousness of the symptoms at the proper time, and adequate knowledge about all aspects of the incidence of these ADRs,[1],[2] which emphasizes the importance of pharmacovigilance (PV). PV can be defined as “the science and actions concerning the recognition, estimation, understanding, and prevention of adverse effects or any other drug-related problem.”[4] To train health professionals with PV competencies, vital aspects of PV should be involved in the educational programs of all health professionals such as doctors, pharmacists, dentists, and nurses.[5] In Yemen, PV-related topics are taught in the 4th and 5th year in the pharmacy undergraduate program. The topics are included in various courses, not in a single course.[6] The curriculum is mainly on pharmaceutical science subjects and biomedical, while lack in the area of clinical and pharmacy practice.
Importance of pharmacovigilance for pharmacy students
Pharmacists should be actively involved in the PV program and activity. Exposure on the PV aspects including developing the knowledge, skills, and right attitudes related to PV should start during the undergraduate level. In addition, the pharmacy colleges can develop training programs that will allow the students to be exposed with activities by the national PV center. It can be anticipated that PV teaching in the primary stage of pharmacy students' careers will help them develop information about the safety of medicines and skills for the harmless use of medicines.[7] In addition, the persistent educational campaign for health workers has proven to be efficient in achieving PV competencies.[8] The pharmacist plays a unique role in monitoring ADRs, either by themselves or with the assistance of other health-care professionals; pharmacists help to diminish the hazards of ADRs by distinguishing, reporting, and evaluating any proposed ADRs. They can also educate, recommend, and inspire medical doctors, nurses, and other health-care professionals to report ADRs.
In Yemen, there is underreporting of ADRs due to the unawareness of most health-care professionals, especially pharmacists, regarding the reporting process. Underreporting is an actual problem within PV; only 6% of all ADRs are assumed to be reported.[9] In 2011, the Supreme Board of Drugs and Medical Appliances (SBDMA) launched an official and approved ADR monitoring system, but regrettably, no ADR data were reported. In 2014, many activities were carried out such as starting the center, building the website and arranging the reporting form, and designing posters and procedures to start disseminating knowledge among the athletes (e.g. use of performance-enhancing substances), pharmacists, and consumers. In addition, Yemeni magazines printed numerous articles concerning PV.[10] Unfortunately, the heartless war in 2015 led to complete disruption of most activities, particularly with regard to the monitoring system. There should be cooperation between the SBDMA and the faculty of pharmacy to restore the activities of ADR reporting and to encourage the addition of PV to the current curriculum system, and the Medicinal Alert Center should support these activities to ensure a qualified reporting process. Recently, the head of the SBDMA directed an official message to many private and governmental universities, emphasizing the need to include the PV as a course of the study. He indicated that most university syllabuses worldwide involve PV courses due to the importance of this issue. He added that health workers are the source and developers of the medical alert and safety system, so they must have enough knowledge about the reporting of ADRs, as well as the management and observation of cases, with the help of the medical alert center.
The prevalence of pharmacists reporting ADR awareness is highly influenced by the level of knowledge and attitude regarding the importance of reporting.[11],[12],[13] There are studies that showed how reporting could be improved by education and training.[14],[15] Another problem facing Yemen is that the pharmacists have less time in contact with the patients to offer the necessary and required information. The function of pharmacists has been changing from the dispensing of medicine to a more clinical role, and pharmacists in our country still have no legal rights to prescribe most of the medications. However, medicines are easily dispensed and bought by the consumers, especially from community pharmacists. For all these problems, PV should be taught to all health-care professionals. The current review focuses on the benefit of PV for pharmacy college students, particularly at Aden University. This article also included a brief evaluation, which aimed to survey students' perceptions about the course.
Pharmacovigilance curriculum for university education
The present educational program is provided by the pharmacy faculty at Aden University and includes the essential issues in terms of ADRs, although it is still limited and does not provide students with a strong basis for the clear and comprehensive knowledge of PV. In the past 20 years, the university syllabus in many countries was based on pharmaceutical chemistry and dispensing. Currently, approximately 20% of the pharmacy program is dedicated to clinical topics and approximately 10% is dedicated to social interactions and prescription management.[10],[16] The theoretical aspects of PV are being taught in several developed countries, but the practical issue is absent in many low- and middle-income countries (LMICs). This might be the stumbling block in establishing a concept. To obtain a satisfactory outcome in PV issues, the experiences of developed countries in this field should be considered. For instance, the UK has attempted to introduce the yellow card scheme (the system of spontaneous reporting in the UK) into the undergraduate medical college syllabi; this system has helped improve PV outcomes in hospitals.[17] In addition, in France, the systematic gathering of ADRs over approximately 20 years has assisted in graduating a generation of physicians with full knowledge of the risks of side effects and rational drug use.[18] The situation differs in LMICs. A study in New Delhi indicated that the knowledge, attitudes, and practices (KAP) concerning ADR monitoring were similar among undergraduates and prescribers, thus it needs major improvement and development in KAP.[19]
The suggested curriculum is based on comprehensive outlines and reference books that offer a broad view of all aspects related to PV.[20],[21],[22] The curriculum should be tailored according to the country's needs because each country has its own PV program. There are key aspects stated by the WHO PV principal curriculum for university education that are essential for the acquisition of knowledge or skills outcomes by future health professionals.[23],[24] This WHO PV program focuses on the clinical aspects of PV in states that only reporting ADRs since the majority of students will be involved in clinical practice and offer patient care facilities. The main intention is to have students with high competence in dealing with the PV aspects. The curriculum should increase in complexity as the academic level increases. It should be started with an introduction to the PV concept and finished with recognizing ADRs, describing the mechanism of ADRs and recommending pharmacotherapeutic interventions.
The curriculum should involve active learning methods instead of passive ones such as case studies, problem-solving, critical thinking, simulations, and the application of activities and training at health centers, to have more effective outcomes. PV education can be added to current courses with limited time investment.
Each university should identify the current gaps in their curricula, invite PV stakeholders to educate the teaching staff, and stimulate the reporting system for ADRs. It is strongly suggested to have an ADR reporting system to provide better prevention of ADRs in health-care centers.[25] The value of the reports produced rests on the knowledge and training of the clinicians.[26] In 2011, the ADR reporting system was established by the SBDMA, although there is no authorized information or reports released by the SBDMA involving the number of ADRs that occurred and how they processed it. However, there was a mutual effort between the academics from the Faculty of Pharmacy at the University of Aden and the official SBDMA in this regard.[27]
Objectives of a pharmacovigilance teaching program
There are many important objectives in introducing PV into the academic curricula of pharmacy colleges.[28] The main intention is to focus on the patient's situation instead of drug orientation. After completion of the course, the student will be able to:
Improve patient safety and quality of care in relation to the use of medicines and other treatment modalitiesImprove community health and safety, especially in relation to the use of medicinesIdentify problems related to the use of medicines and communicate the findings in a timely mannerContribute to the assessment of benefit, harm, effectiveness, and risk of medicines, leading to the prevention of harm and maximization of benefitPromote the safe, rational, and more effective (including cost effective) use of medicinesEnhance understanding, education, and clinical training in PV and its effective communication to the public.Content of the teaching program
The content of the current clinical pharmacy syllabus is outlined in [Table 1]. The teaching outlined occupies a total teaching time of 10 h/week, which is divided into theory (4 h/week), case studies (theory) (4 h/week), and hospital experience (practical) (2 h/week).
Table 1: Content of the current clinical pharmacy syllabus for pharmacy undergraduate students at Aden UniversityThe course emphasizes an extended role of pharmacists that is patient oriented rather than drug oriented. The course is made up of four components:
Clinical pharmacokinetics: Practical application of pharmacokinetics in therapeutic drug monitoring and its clinical applicationPharmacy practice skills: Acquiring skills to enable the pharmacist to help the public optimize drug treatment by monitoring and avoid drug interactions and ADRsPharmacy practice research: Gain expertise on the evaluation of medicine through research and utilization reviewsEvidence-based pharmacy, evidence-based data sources, answerable clinical questions (PICO), and levels of evidence-based evaluations of medicine and research: study design, drug information systems, and writing a research project.After completion of the course, the student is expected to be able to:
Monitor drug therapy for medications with a narrow therapeutic index and calculate the most important drug pharmacokinetic parametersRecognize drug interactions due to pharmacokinetics and other mechanismsRespond to questions regarding drug information and source evidence-based resources for drug informationConduct a clinical trial and interpret the clinical outcome dataPredict ADRs and take action to reduce the number of ADRs that occurTake a patient medical history and complete an admission recordInterpret laboratory clinical dataConduct research and write research reports.This syllabus contains some aspect of PV; however, the curriculum, which is based on the WHO PV guideline, aims to familiarize students who graduate from the college of pharmacy with the aspects and foundations of PV, which can be summarized in the following points [Table 2]:
Table 2: Outline of the main aspects and skills that form a pharmacovigilance core syllabus for university education based on the WHO pharmacovigilance curriculumRealizing the value of PV within the pharmacotherapy backgroundAvoiding ADRs at the proper timeIdentifying ADRs at the time of occurrenceProper ADRs management; andReporting ADRs.The main objective of this program is to provide graduate students with the clinical aspects of PV. The students will be in direct contact with the patients, so they must have a comprehensive knowledge of the detailed aspects of the PV such as the safety of the prescribed drugs, possible risk factors, clinical manifestation of early symptoms, and reporting of ADR cases. The desired outcome can only be achieved by involving PV in the current curriculum at the pharmacy college.
Teaching–learning evaluation and methods
Pharmacy colleges must apply the teaching and learning method that students learn PV best. As academician, we need to use the different teaching styles that will engage and motivate the students to learn PV. The teaching methods used at Aden University can be summarized in the following points:
Lectures and seminars – in addition to the didactic lectures, seminars were organized occasionally on a selected PV topicsHospital and primary health-care (PHC) unit experience – Students were arranged to visit the hospital and PHC settings; they learned the activities that are carried out in these institutionsGroup work – students worked in group on a research project assigned to themAssignment – this can be a paper writing on a specific PV topic.With regard to the contents, the theoretical part can be evaluated by means of short answer type questions and multiple-choice questions (MCQs). A group activity could be the best way to assess ADR reporting. The overall evaluation for the course could be carried out by the final written examination and assignment.
An Evaluation of the Pharmacovigilance Course among Students at Aden University
Our team conducted an evaluation of the PV course among our students at Aden University, Faculty of Pharmacy. Fifty 5th-year students participated in the survey that was conducted in December 2019. The ethics approval was obtained from the ethical committee of faculty of medicine. Verbal consent was obtained from the students. If the student responds to the evaluation, it indicates that he/she approved to participate.
The survey tool was developed from a previous literature review about the evaluation of courses; it was modified after been reviewed by two faculty members from different universities. It aimed to meet the objective of the PV course evaluation and translated to Arabic language. The content of the English version is attached in Appendix 1.
The tool was distributed to fifty students after the PV lecture, and they were given 15 min to answer the open-ended questions. The data were collected, coded, and subjected to a content analysis because the tool contained open-ended questions.
The findings indicated that most students wanted to know more about the types of ADRs, with examples and pictures of their harmful effects. In addition, students wanted to know the common medication errors in dispensing drugs because they will face all these problems in their future employment. Some students lacked an understanding of the causal relationship between ADRs and risk assessment, and some were unsure how to fill out reporting forms or did not know where these forms were available. They preferred to have the MCQs on the exam as opposed to the open-ended questions.
Students suggested training seminars to fill out reporting forms, raising awareness, and creating day-to-day awareness among health workers and the public and improving communication with the national PV center.
Most students felt the importance of their studies to raise the level of their performance and competence in the future; they were grateful and satisfied with their teachers and reported that the teaching of the course was very good.
Conclusions Insertion of PV into the current academic syllabus is an essential aspect to ensure the safe use of medicines in poor-resource setting. The suggested curriculum has a hierarchical harmonized structure with a gradual increase in complexity. The theoretical section is reinforced by practical training. The main aim of applying the curriculum is to have a new generation of pharmacists that have enough PV knowledge and skill to be active participants in the country PV system in LMICs.
