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. All submissions to ckj have undergone peer review.
The ckj Editor-in-Chief is Professor Alberto Ortiz, Madrid, Spain. ckj has a separate Editorial Board consisting of internationally renowned experts in Nephrology.

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 has been selected to be indexed in the Science Citation Index and will thus receive its first impact factor, based on 2018 citations, in June 2019. ckj’s estimated 2018 impact factor is 2.987.

ckj received 636 submissions (479 original and 157 revised) in 2018. The overall acceptance rate was 26%. The time from acceptance to online publication was 5-6 weeks. In 2018, the Journal received a total of 887,983 full-text downloads, an increase of 45.6% compared to 2017.

ckj is widely promoted on social media (Facebook, ckj app, Twitter etc.). 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 blogs.

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 September 2018, we launched the cardio-renal collection, a new virtual Journal including cardio-renal medicine articles from NDT, ckj and the European Society of Cardiology Journals published by OUP. The launch coincided with World Heart Day on 29th September 2018.

ckj published one Supplement in 2018 entitled ‘Towards a holistic view in the management of ADPKD—state-of-the-art and upcoming approaches’, sponsored by Otsuka Pharmaceutical Europe.

Important marketing initiatives in 2018 included: author fee waiver promotion, 'Best of 2017' (a collection of the most downloaded, most cited, and highest-Altmetric scoring ckj articles published in 2017), the World Kidney Day article collection, conferences: ERA-EDTA Congress, ASN Kidney Week, highly cited content / impact factor campaign, cardio-renal collection promotion.
