Why Iraqi doctors should be interested in research

In spite of the various research difficulties described in the previous article (Why Iraqi doctors are not interested in research), Iraqi doctors should, in my opinion, be interested in research for the following reasons:
1.     Answers to local problems:
Local research even if it is a simple survey sheds light and may produce answers to some local problems. It does not have to produce important discoveries on a worldwide scale. After all, among the huge amount of research published in thousands of medical journals worldwide, very few constitute really important discoveries.
2.     Experience for the future:
With time, research experience accumulates and results are likely to improve.
3.     Education:
Research is highly educating. Knowledge is gained by reading and discussing the subject of research and related subjects. The researcher also learns the ways of obtaining knowledge like searching the internet and using the library.
4.     Promotion of scientific and critical thinking:
By following the scientific method of making a hypothesis, collecting data and modifying the hypothesis, research promotes scientific thinking. The researcher learns how scientific knowledge is obtained and realizes that so called scientific facts are in fact hypotheses with various degrees of convincing power. They are not certainties and that is why they keep changing. This develops in him a skeptical and questioning mind which is important not only in research but also in practice and in life in general. Knowing how various workers frequently differ about the same subject is a warning that one should not take everything he reads in a book or a journal or hears in a lecture as established facts.
5.     Reflection on practice
a.     The scientific method is not confined to research. It should be the basis of practice too. In fact the clinician is involved in research daily by trying to make a diagnosis of his patient’s illness and find solutions for his problems. Fever in a patient, for example, is a scientific problem. A hypothesis about its cause should be made after the initial information. Data is then collected through history taking, physical examination and various tests to strengthen or modify the hypothesis once or more times. Actions are then taken on the basis of the final hypothesis. This is what the scientific method is all about.
b.     Awareness of observer error and observer bias, common precautions in research, is reflected on interpretation of clinical findings and various tests made during daily work.
c.      Awareness that association is not necessarily causation, a common precaution in research, reflects on clinical work. Jaundice in a patient with a positive hepatitis virus BsAg is not necessarily caused by hepatitis B virus.
d.     Knowing how reference values are obtained makes interpretation of patients’ figures more intelligent. You may e.g. accept a figure slightly outside the reference range because you know that 5% of normal people are so.
e.      Research improves logic and shows its limitations. Treatment of various illnesses is based on trials done on a number of patients somewhere in the world and the results are generalized to include all patients all over the world (induction in logical terms). Why should your patient behaves in the same way as those patients?! In fact induction is the logical basis of most medical knowledge, not only treatment. One should therefore not be surprised to find so many differences between practice and the book. What should be surprising is the presence of so many similarities!
