Clinical Kidney Journal (CKJ) (

Clinical Kidney Journal (CKJ) is one of the official publications of the ERA-EDTA. It is a fully open access, online only journal publishing bimonthly. The journal is an essential educational and training resource integrating clinical, translational and educational research into clinical practice. The CKJ Editor-in-Chief is Professor Alberto Ortiz, Madrid, Spain. The Editorial Board counts 30 internationally renowned experts in nephrology. All submissions to CKJ have undergone peer review.

CKJ became open access in 2015, meaning that all CKJ content (including past publications) is included in PubMed via PubMed Central. To fully support and further launch CKJ, the ERA-EDTA Council decided to waive all author charges in 2015, 2016, 2017, 2018, and 2019. In 2016, CKJ was accepted for indexing in the new Emerging Sources Citation Index (ESCI) database from Clarivate Analytics (previously Thomson Reuters). In 2018, CKJ was selected to be indexed in the Science Citation Index and received its first impact factor of 2.975 in June 2019, based on 2018 citations. The average Altmetrics score is 14.

CKJ received 1085 submissions (845 original and 240 revised) in 2019. The overall acceptance rate was 17.5%. The time from acceptance to online publication was 5-6 weeks. In 2019, the journal received over 730,000 full-text downloads.

CKJ publishes editorials, reviews, original articles, exceptional cases, and letters to the editor. CKJ also welcomes reviews on CKD hotspots around the world.

CKJ is widely promoted on social media (Facebook, CKJ app, Linkedin, Twitter, Instagram). Each month a selection of CKJ articles is promoted in the ERA-EDTA newsletter, and important CKJ articles are regularly selected for press releases or blog posts.

We add Twitter handles to 
CKJ submissions because sharing a paper via Twitter results in a higher Altmetrics score (the amount of attention an article has received online, in social media, and from news sites). We offer our reviewers the possibility to get recognition for their reviews via Publons. We also encourage our authors to register for and submit their ORCID IDs alongside their papers. By registering for an ORCID ID, authors can be sure that their work will be properly attributed and referenced, and made easily discoverable. These ORCID IDs are then added to our proofs.

In 2019, we continued the cardio-renal collection, a virtual journal including cardio-renal medicine articles from NDTCKJ and the European Society of Cardiology journals published by OUP. Important marketing initiatives in 2019 included: author fee waiver promotion, 'Best of 2018' (a collection of the most downloaded, most cited, and highest-Altmetric scoring CKJ articles published in 2018), the World Kidney Day article collection, highly cited content / impact factor campaign, promotion of Publons, the cardio-renal collection, and the ERA-EDTA journals app, conferences: ERA-EDTA Congress, ASN Kidney Week.
