A word of welcome

Welcome to this module in Applied Pharmacoepidemiology. We trust that you will enjoy and complete the course successfully. This course will demand perseverance and discipline from you. It is very satisfactory, however, to realise how your perspective widens while working through each study unit.

Pharmacoepidemiology is a relatively new field of study, with concepts, methods and applications that have made increasing contributions to health care as the field has evolved over the past few decades. This module gives you an overview of the scope of pharmacoepidemiology and also describes the potential of this field, in terms of what it can achieve, the strengths, weaknesses and limitations of the different pharmacoepidemiological methods. It will also try to give you an idea of possible future developments in this area of science.

Pre-requisite

The pre-requisite in order to enter this course is a B.Pharm. degree or similar qualification approved or endorsed by the Senate.

Rationale

Your aim in studying this module is to obtain knowledge of the disciplines pertaining to pharmacoepidemiology and also to partially fulfil the requirements to obtain the M.Pharm degree. This module may be regarded as complementary to FPHA811 the other module in the M.Pharm programme in being a discipline required to understand the basic concepts of pharmacoepidemiology applicable in a pharmaceutical practice environment or a similar health care environment.

The text format in this study guide explains the method of self-study; it helps you work through the study units and illustrates how to answer questions. An answer key will be given at the end of each study unit. (Some answers will be given and others will not – the “insight” type of questions.)

In Study Unit 1 the learner will be exposed to some introductory material on the underlying aspects and definitions of pharmacoepidemiology.

In Study Unit 2 the learner will be exposed to the learning of Medical Surveillance and Outbreaks of Disease.

In Study Unit 3 the learner will be exposed to the learning of Observational Study Designs in Epidemiology.

In Study Unit 4 the learner will be studying Experimental Study Designs.

In Study Unit 5 the learner will be exposed to the learning of Data Identification and Analysis.

In Study Unit 6 the learner will be studying Risk Assessment.

In Study Unit 7 the learner will be exposed to the learning of the principles of Screening and Diagnostic Testing.

In Study Unit 8 the learner will be studying aspects of Post-Marketing Surveillance.

In Study Unit 9 the learner will be studying an overview of Drug Utilisation Studies.

In Study Unit 10 the learner will be studying the principles of Evidence-based medicine.

In Study Unit 11 the learner will be studying Pharmacoepidemiology in Pharmacy Practice.

Module outcomes

After completion of the module the student should

  • have advanced and comprehensive specialist knowledge of certain epidemiological and pharmacoepidemiological principles, concepts and techniques, as well as of evidence-based medicine;

  • demonstrate the ability to plan and apply/propose appropriate epidemiological research designs in the field of medicine consumption;

  • demonstrate skills to identify, collect and analyse appropriate data needed for pharmacoepidemiological studies by making use of correct data analysis techniques, while at the same time applying the principles of risk and risk-determining techniques to pharmacoepidemiological data; and

  • demonstrate skills for reviewing published reports critically with the aid of meta-analyses and then compiling own results in a pharmacoepidemiological report of a prescribed format.

Study materials

One specific textbook and a separate READING COMPENDIUM are prescribed. The module consists of a folder with text in order to serve as a study guide allowing you to accomplish this course.

The one book and the reading compendium are therefore prescribed but it is, however, in your own interest to read as widely as possible (see bibliography listing at the end of the module) to improve your knowledge and skills in the field of Pharmacoepidemiology.

The following textbook is prescribed for this module:

Title: Pharmacoepidemiology: Principles and Practice (The specific handbook is out of print and we will provide you with a copy)

Authors: Waning B & Montagne M

Year of publication: 2001

Publisher: McGraw-Hill

General overview

Action verbs

Some action verbs are included, in order to provide clarity of what is expected of you as a student. Please study them and make sure that you understand the meaning of each.

  • Analyse

Identify parts or elements of a concept and describe them one by one.

EXAMPLE: Analyse a typical lesson structure and describe each aspect in detail.

  • Compare

Point out the similarities (things that are the same) and the differen­ces between objects, ideas or points of view. The word “contrast” can also be used. When you compare two or more objects, you should do so systematically - completing one aspect at a time. It is always better to do this in your own words.

EXAMPLE: Compare philosophical and empirical knowledge. Compare the views of Piaget and Ausubel about the nature of learning.

  • Criticise

This means that you should indicate whether you agree or disa­gree about a certain statement or view. You should then describe what you agree/disagree about and give reasons for your view.

EXAMPLE: Write critical comments about the progressive liberal view of education.

  • Define

Give the precise meaning of something, very often definitions have to be learnt word for word.

EXAMPLE: Define the concept curriculum.

  • Demonstrate

Include and discuss examples. You have to prove that you understand how a process works or how a concept is applied in real-life situations.

EXAMPLE: Give a written demonstration of the application of the procedural moments of a lesson.

  • Describe

Say exactly what something is like; give an account of the charac­teristics or nature of something; explain how something works. No opinion or argument is needed.

EXAMPLE: Describe the characteristics of philosophical thought.

  • Discuss

Comment on something in your own words. Often requires debating two viewpoints or two different possibilities.

EXAMPLE: Discuss the differences between objectives and goals.

  • Distinguish

Point out the differences between objects, different ideas, or points of view. Usually requires you to use your own words.

EXAMPLE: Distinguish between a positivistic and a hermeneutic view of science.

Clarify or give reasons for something, usually in your own words. You must prove that you understand the content. It may be useful to use examples or illustrations.

EXAMPLE: Briefly explain the following research methods:

(a) The experiment

(b) Correlation studies

  • Identify

Give the essential characteristics or aspects of a phenomenon e.g. a good research design.

EXAMPLE: Identify the characteristics in a text about the research process, which is indicative, a good research design.

  • Illustrate

Draw a diagram or sketch that represents a phenomenon or idea.

EXAMPLE: Explain the life cycle of a butterfly. Write a short essay and illustrate this model.

  • List

Simply provide a list of names, facts or items asked for. A particular category or order may be specified.

EXAMPLE: List ten psychosocial problems associated with alco­hol abuse in high school pupils.

  • Motivate

You should give an explanation of the reasons for your statements or views. You should try to convince the reader of your view.

Warning against plagiarism



ASSIGNMENTS ARE INDIVIDUAL TASKS AND NOT GROUP ACTIVITIES. (UNLESS EXPLICITLY INDICATED AS GROUP ACTIVITIES)

Copying of text from other learners or from other sources (for instance the study guide, prescribed material or directly from the internet) is not allowed – only brief quotations are allowed and then only if indicated as such.

You should reformulate existing text and use your own words to explain what you have read. It is not acceptable to retype existing text and just acknowledge the source in a footnote – you should be able to relate the idea or concept, without repeating the original author to the letter.

The aim of the assignments is not the reproduction of existing material, but to ascertain whether you have the ability to integrate existing texts, add your own interpretation and/or critique of the texts and offer a creative solution to existing problems.

Be warned: students who submit copied text will obtain a mark of zero for the assignment and disciplinary steps may be taken by the Faculty and/or University. It is also unacceptable to do somebody else’s work, to lend your work to them or to make your work available to them to copy – be careful and do not make your work available to anyone!
