  Abstract 


Objective: There is a global dearth of clinical pharmacologists despite the critical role clinical pharmacology plays in health-care delivery, not only in developing economies like Nigeria but worldwide. There is also a growing negative attitude among undergraduate medical students towards pharmacology. In a bid to control this trend, there is a need to assess the attitude and feedback of medical students in teaching and learning of pharmacology. This will provide a platform from which appropriate intervention can be effected. Materials and Methods: It was a cross-sectional descriptive study using semi-structured self-administered questionnaires. A total of 167, 500 and 600 levels medical students participated in the study selected by multistage sampling technique. The questionnaire was designed based on a 4-point Likert scale, containing three sections. The data generated were analyzed using SPSS statistics version 20. Results: Majority of the respondents were males within age brackets of 18–25 years. Only 22.6% (odds, 0.29; 95% CI, 0.20–0.42) agreed to consider taking pharmacology as a specialty at postgraduate training; none was strongly inclined. Majority (98.7%, odds, 76.5; 95% CI, 20.8–281) of the participants agreed that pharmacology is important, exciting, and indispensable in clinical practice. About 72.9 of the students (odds, 2.69; 95% CI, 1.89–3.83) admitted that pharmacology was difficult and volatile. Slightly over 70% favored audiovisual-aided lecture during class session. Conclusion: Despite demonstrated interest in pharmacology, there was general negative attitude toward it among the respondents.

  Introduction Top


Pharmacology is the fulcrum upon which clinical practice revolves and it builds on foundations laid down by physiology, biochemistry, genetics, pathology, and cell biology. Rational drugs prescription is an integral skill that must be acquired by every medical doctor.[1] In many medical schools, medical students have limited exposure to pharmacology and upon graduation they tend to rely mainly on information dished out by pharmaceutical companies for sales promotion. This attitude provided fertile ground for new medical graduates' poor abilities to recognize and manage intricate medication or treatments, and ultimately, they cannot ensure sound rational drug use.[2] Consequently, polypharmacy, drug–drug interactions, and adverse drug reactions ensue. Pharmacology, though both basic and clinical, is central to therapeutic success. Rational therapeutic decisions can only be taken with sound knowledge of pharmacology.[3] Most students at undergraduate level consider it as complex, impulsive, and parched.[4] Students often have to put in great effort when it comes to understanding pharmacology as a course. This is because it requires, among other things, sound-integrated chemical, physiological, and precise thinking.[5] Equally important is the basic teaching skills among lecturers who taught pharmacology in undergraduate medical colleges. Most of these lecturers are trained medical doctors who double also as researchers and clinicians. Despite their expertise on the subject of pharmacology and research, they most often than not are lacking in basic teaching skills.[6]

A significant number of drug poisonings cases were due to use of prescribed drugs; this occurs because of a poor grasp of pharmacological knowledge among prescribers of drugs. There is a dearth of clinical pharmacologists even in developed climes, who are supposed to train health professionals to avert dangers associated with bad prescription habits.[7] The American College of Clinical Pharmacologists opines that there is a pressing call to develop on the clinical pharmacology education in undergraduate physicians.[8]

Medical graduates, as team leaders of health-care delivery, must have a sound knowledge of pharmacology for them to prescribe safely and effectively. Studies have shown that about 7–10% of prescriptions emanating from newly graduated doctors contain errors.[9] This is more so with a high turnover of new drugs with complex pharmacokinetic and pharmacodynamic profiles, evolving genetic and epigenetic variables that influence drugs characteristics in the body. Coupled with this is the need to avoid adverse drug reactions due to prescription errors which now constitute formidable challenges to effective health-care delivery even in best of centers, hence the emergence of personalized medicine. Rational prescription also promotes cost-effectiveness in health-care systems.[9]

The aim of this study therefore was to assess the perception of medical students of Usmanu Danfodiyo University, Sokoto, on pharmacology and obtain a feedback upon which further study can be built, to improve the teaching and learning of pharmacology in the study area.


  Materials and Methods Top


Study design, settings, and sample selection

It was a descriptive cross-sectional survey, involving all final and semi-final year medical students of College of Health Sciences, Usmanu Danfodiyo University, Sokoto, Nigeria. Pharmacology is offered as a course in UG III and UG IV in the Department of Pharmacology and Therapeutics. The period of its teaching spanned over a period of four semesters after which students sit for the second MBBS professional examination. All the lecturers were qualified medical doctors at various levels of academic cadres from professors to lecturer II. A total of 167 volunteers were recruited by multistage sampling technique in the study and participation was entirely voluntary. Each participant signed informed consent form before commencement of the study. Stage I: total number of medical students was obtained from the administrative office of the college. Stage II: number of clinical year students was extracted from the overall number of medical students. Stage III (criterion sampling): only students who wrote and passed pharmacology and were in the next levels (500 and 600 levels) where pharmacology was not offered were eligible for participation to avoid bias.

Questionnaire design, validation, and data collection

The questionnaire was designed from validated questionnaires of previous studies [10],[11],[12] that assessed attitudes and perception of final medical students on pharmacology with slight adaptation to reflect our local needs. The questionnaire was validated for test and retest reliability through a pilot survey on clinical year medical students of University of Benin before start of the study. It comprised three sections; Section A for demographic profiles of respondents, Section B on the perception of pharmacology, and Section C for open-ended questions. It was designed on 4-point Likert scale to evoke forced choice. The administered questionnaires were distributed and retrieved by coresearcher (ARZ) on the spot of administration. Those that could not fill the questionnaire were given until the following day for collection.

Data analysis

The data generated were analyzed with SPSS Statistics version 20 for crude descriptive statistics, proportions, percentile scores, odds, and 95% confidence intervals. Percentile scores for each item of the perception assessed. On 4-point Likert scale, strongly agreed was scored 4, agreed 3, disagreed 2, and strongly disagreed 1. We further calculated proportions, odds, and confidence intervals for each item.

For open-ended questions and demographic profiles, we employed descriptive statistics.


  Results Top


After data mining and cleaning, a total of 155 questionnaires were analyzed, a response rate of 93%. Majority of the respondents were males 105 (67.7%), within the age bracket of 18–25 years (66.5%) and single 139 (89.7%). None of the respondents strongly agreed to pursue pharmacology as career at post graduate level. Only 35 (22.6%) wished to take pharmacology as a specialty. Majority preferred reading textbooks (69, 38.1%) as source of reference. Chemotherapy, cardiovascular, and central nervous systems (CNS) were considered the most important topics in clinical practice 142 (91.6%). Autonomic nervous systems (ANS) and CNS were cited as most difficult 152 (98.1%). Audiovisual-aided teaching method was the most favored by the respondents 109 (70.3). Percentile scores of participants on attitude towards Pharmacology has been shown in [Table 1].

  Discussion Top


Majority of the participants in this study were males, a finding that sharply contrasted observations in similar studies in India and Malaysia.[12],[13] This may not be unrelated to gender inequality against girl- child education in northern Nigeria, specifically where the study was carried out and Nigeria in general.

Various governments in the past have tried to minimize the gap but efforts remained much to be desired due to cultural, economic, and religious among other factors.[14],[15] This study revealed very low interest of respondents to pursue pharmacology as a career at postgraduate level [Table 2]. The finding was consistent with observation made in India in which only 10.9% of students interviewed considered pharmacology as a career at postgraduate level.[12] This was really disturbing taking into cognizance the dearth of clinical pharmacologists not only in Nigeria but globally and their increasing roles in successful health-care delivery and research.[16] This is more so with emergence of personalized medicine with clinical pharmacologists playing very critical role.

The opinion expressed by majority of participants in this survey that pharmacology was difficult and volatile was comparable to the findings in a similar study [Table 2].[4] This may be due to unsuitable teaching technique as in most cases the lecturers in the medical colleges do not possess basic teacher training education despite their expertise in research and in what they lecture.[6],[17] This may be the reason for poor response from students when asked if they wanted to specialize as pharmacologists at postgraduate level despite enthusiasm in the subject. It serves as a wakeup call to lecturers to review teaching methods to stem the tide of this ugly perception and this can effectively be done by acquiring basic teacher education.

It is however gratifying that virtually all students regarded pharmacology as exciting and very important in clinical practice and only a few felt that studying of pharmacology was a waste of time [Table 3]. This observation reechoes the findings in sister survey in which 62% of the participants interviewed regarded pharmacology above all other subjects in medical school in terms of importance.[10] This is reassuring and with suitable teaching methods the general apathy of medical students toward pharmacology can be reversed. Establishing distinct health education departments across colleges of medicines will go a long way in strengthening teacher education among the lectures that play triple roles of clinicians, teachers, and researchers.

Feedback from students is critical in modification and reviewing teaching methodologies to meet ever dynamic realities of evolving field of science like pharmacology.[18],[19] Reinforcing learning model with discussion has been proposed as one of the best method of teaching pharmacology among undergraduate students.[20] The need to evolve teaching method that appeals to students so as to encourage them to take up postgraduate training to meet current challenges of dearth of clinical pharmacologists cannot be over emphasized.

In this study, audiovisual-aided method of teaching was reported to be the most favored among participants. This observation agrees though lower than 92.7% findings reported in a similar study in Lagos.[11] This finding may be useful especially in teaching such topics as ANS and CNS that were reported to be more difficult and conceptual in this survey and similar reports.[12]


  Conclusion Top


In conclusion, this study has shown that despite demonstrated interest, there was negative attitude toward pharmacology among the respondents and further painted a gloomy picture of addressing shortage of clinical pharmacologists. It is possible that appropriate teaching techniques acquired through teacher education by lecturers may help in curbing this negative attitude.

Limitation of study

The study was merely descriptive; however, its findings can provide basis upon which targeted intervention can be mounted.
