Scope Founded in 1923, one year after the first anaesthetic journal was published by the International Anaesthesia Research Society, the British Journal of Anaesthesia remains the oldest and largest independent journal of anaesthesia. It became the journal of The College of Anaesthetists in 1990. The College was granted a Royal Charter in 1992. Although there are educational links between the BJA and the College, the journal retains editorial independence. BJA publishes original articles in all branches of Anaesthesia. Submitted manuscripts are subject to stringent review to ensure that the journal only contains papers of the highest standard.

SJR

The SJR is a size-independent prestige indicator that ranks journals by their 'average prestige per article'. It is based on the idea that 'all citations are not created equal'. SJR is a measure of scientific influence of journals that accounts for both the number of citations received by a journal and the importance or prestige of the journals where such citations come from It measures the scientific influence of the average article in a journal, it expresses how central to the global scientific discussion an average article of the journal is.

Citations per document

This indicator counts the number of citations received by documents from a journal and divides them by the total number of documents published in that journal. The chart shows the evolution of the average number of times documents published in a journal in the past two, three and four years have been cited in the current year. The two years line is equivalent to journal impact factor ™ (Thomson Reuters) metric.
