Thanks to our peer reviewers

The publication of Issue 4 marks the completion of Volume 6 of Learning Health Systems. An open access publication, the journal has advanced research and scholarship on learning health systems in partnership with our reviewers. With indexing in multiple major sources and the recent news that we will have an official impact factor next year, we believe the journal is now on a sustainable, positive trajectory.

We were also delighted to learn that articles from the journal were downloaded over 100 000 times in 2021.

The journal has also published six Special Issues: “Patient Empowerment and the Learning Health System” (v.1); “Ethical, Legal, and Social Implications of Learning Health Systems” (v.2); “Learning Health Systems: Connecting Research to Practice Worldwide” (v.3); “Human Phenomics and the Learning Health System” (v.4); “Collaborative Learning Health Systems: Science and Practice” (v.5); and “Education To Meet the Multidisciplinary Workforce Needs of Learning Health Systems” (v.6). Our talented guest editors have been instrumental in helping these Special Issues come to fruition.

We are keenly aware that these achievements would not have happened without the dedicated efforts and insightful comments of all those individuals who accepted invitations to review submitted articles. With busy schedules and full commitments in the midst of the Covid-19 pandemic, these individuals found the time and energy to contribute their expertise to our authors to help ensure that their papers met (and often exceeded) the journal's high standards for publication.

Please accept our sincere gratitude for your outstanding efforts.

Charles P. Friedman, Editor in Chief
