Pharmacoepidemiology

Pharmacoepidemiology is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Pharmacoepidemiology rather than just read about it. In short: Pharmacoepidemiology is the study of the uses and effects of drugs in well-defined populations. To accomplish this study, pharmacoepidemiology borrows from both pharmacology and epidemiology.

Key takeaways

Pharmacoepidemiology belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Pharmacoepidemiology to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Pharmacoepidemiology from memory before moving on to harder problems.

Reference excerpt

Pharmacoepidemiology is the study of the uses and effects of drugs in well-defined populations. To accomplish this study, pharmacoepidemiology borrows from both pharmacology and epidemiology. Thus, pharmacoepidemiology is the bridge between both pharmacology and epidemiology. Pharmacology is the study of the effect of drugs and clinical pharmacology is the study of effect of drugs on clinical humans. Part of the task of clinical pharmacology is to provide a risk benefit assessment by effects of drugs in patients:

doing the studies needed to provide an estimate of the probability of beneficial effects on populations, or assessing the probability of adverse effects on populations. Other parameters relating to drug use may benefit epidemiological methodology. Pharmacoepidemiology then can also be defined as the transparent application of epidemiological methods through pharmacological treatment of conditions to better understand the conditions to be treated. Epidemiology is the study of the distribution and determinants of diseases and other health states in populations. Epidemiological studies can be divided into two main types:

Descriptive epidemiology describes disease and/or exposure and may consist of calculating rates, e.g., incidence and prevalence. Such descriptive studies do not at this time use health control groups and can only generate hypotheses, but not test them. Studies of drug use would generally fall under descriptive studies. Analytic epidemiology includes two types of studies: observational studies, such as case-control and cohort studies, and experimental studies which include clinical trials or randomized clinical trials. The analytic studies compare an exposed group with a control group and usually designed as hypothesis testing by studies. Pharmacoepidemiology benefits from the methodology developed in general epidemiology and may further develop them for applications of methodology unique to needs of pharmacoepidemiology. There are also some areas that are altogether unique to pharmacoepidemiology, e.g., pharmacovigilance. Pharmacovigilance is a type of continual monitoring of unwanted effects and other safety-related aspects of drugs that are already placed in current growing integrating markets. In practice, pharmacovigilance refers almost exclusively to spontaneous reporting systems which allow health care professionals and others to report adverse drug reactions to the central agency. The central agency combines reports from many sources to produce a more informative profile for drug products than could be done based on reports from fewer health care professionals. In Australia, a 10% sample of all people eligible for government-subsidised medicines by the Pharmaceutical Benefits Scheme (PBS) are made available for research purposes. Licences are held between Services Australia, who hold the data for the PBS, and academics at Monash University, University of New South Wales, University of South Australia and the University of Western Australia to use the 10% sample for research purposes. Research outputs from these data have to be approved by Services Australia prior to publication. These data create a useful picture of all dispensed medicines in Australia and allow for pharmacovigilance and to explore trends in medicines usage.

Worked examples

Example 1 — a first encounter with Pharmacoepidemiology

Start with the simplest possible case. Write down what Pharmacoepidemiology claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Pharmacoepidemiology before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Pharmacoepidemiology ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Pharmacoepidemiology

In research: Pharmacoepidemiology appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Pharmacoepidemiology in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Pharmacoepidemiology is common in secondary-school and first-year university syllabi. It links to neighbouring topics Epidemiology, Pharmacology, so understanding it makes those chapters shorter.
In everyday life: Look for Pharmacoepidemiology outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Pharmacoepidemiology in simple terms?

Pharmacoepidemiology is the study of the uses and effects of drugs in well-defined populations. To accomplish this study, pharmacoepidemiology borrows from both pharmacology and epidemiology.

Why does Pharmacoepidemiology matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Pharmacoepidemiology?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.

What does this page cover?

It gives you a compact reference excerpt plus original lgStudy explanations, examples, applications and study material on Pharmacoepidemiology.
