Yes professor it is very important to get it

Many Thanks.

Dear Mainul,

generally speaking, every time you conduct a study in which patients are involved, an ethical approval is needed. On the other hand, if your research is observational and/or retrospective, you shouldn't find ethical obstacles and therefore you should receive approval in a very short time. Just to be sure, it is preferable to insert an ethical disclosure in every paper that includes patients, specifying that you strictly observed the Helsinki Declaration.

Good luck with your work,

Davide

Many Thanks

Detail Clarification.

Regards.

Yes they do! As already mentioned it shouldn't be a problem to get it in these type of studies.

Apart from that, most (reliable) journals will also ask for this if you submit your findings as an article.

Thanks.

Sometimes such study may be ethical but it's publication may raise some ethical dilemma in terms of stigma relating to such reporting.

However, it seems you plan to use secondary data like hospital records: In that case, I think you might simply seek for ethical guidance and waiver from IRB.

Thanks.

I am not doing the research.

I received a manuscript for review.

Thereafter, raises the issue of ethical approval.

I felt should have a general opinion.

This was a original study utilizing government data. I think researcher must need to have proper approval to conduct study from appropriate authority. Otherwise the study will loose authentication.

Regards.

It is convenient to have signed it . It brings you confidence in the results achieved

Dear Sir/Madam,

All medical research require ethical approval to safeguard human right like patient consent, institutional committee approval.

Best regards.

Ethical approval should be taken for all studies involving human being whether it is hospital based or field based. It reflects our comittment to human welfare

Attention to ethical issues can facilitate the effective planning, implementation, and growth of a variety of public health programs and research activities.

Please find a review article by Steven S Coughlin

"Ethical issues in epidemiologic research and public health practice"

And another important work for this issue was Prepared by CIOMS in collaboration with WHO

"International Ethical Guidelines for Epidemiological Studies"

It is a master of science work and 130 pages with free to access via following links below

It says: "Progress in medical care and disease prevention depends upon an understanding not only of physiological and pathological processes but also of the social, cultural, economic, and other environmental determinants of health, including the effects of the healthcare system and other social institutions. Producing that understanding requires performing research involving human subjects. Such research should be carried out only by, or strictly supervised by, suitably qualifi ed and experienced investigators under accepted ethical guidelines."
