Scope/Description:

BMJ Open is a medical journal. We consider papers addressing research questions in clinical medicine, public health and epidemiology. We also welcome studies in health services research, health economics, surgery, qualitative research, research methods, medical education, medical publishing and any other field that directly addresses patient outcomes or the practice and delivery of healthcare. Our focus is on research that is relevant to patients and clinicians. We do not publish studies conducted in animals, laboratory studies not linked to patient outcomes, papers reporting solely physiological or biomechanical results from healthy participants, anatomy, cell biology or non-clinical psychology. All research study types are considered, from study protocols through phase I trials to meta-analyses. This includes specialist studies and studies reporting negative results.

Impact Factor

Impact factor (IF) is a scientometric factor based on the yearly average number of citations on articles published by a particular journal in the last two years. A journal impact factor is frequently used as a proxy for the relative importance of a journal within its field. Find out more: What is a good impact factor?

III. Other Science Influence Indicators

Any impact factor or scientometric indicator alone will not give you the full picture of a science journal. There are also other factors such as H-Index, Self-Citation Ratio, SJR, SNIP, etc. Researchers may also consider the practical aspect of a journal such as publication fees, acceptance rate, review speed.

H-Index

The h-index is an author-level metric that attempts to measure both the productivity and citation impact of the publications of a scientist or scholar. The index is based on the set of the scientist's most cited papers and the number of citations that they have received in other publications
