The supplement draws upon research and shared lessons learned across Kaiser Permanente and other health care delivery systems. Publication costs for this supplement were covered by Kaiser Foundation Health Plan/Hospital as part of its telehealth evaluation program. The views and opinions expressed in the supplement are the responsibility of the authors and do not represent the official views of Kaiser Permanente. The funder had no role in: collection, management, analysis, or interpretation of data; preparation of manuscripts; or the decision to publish a journal supplement.

We are grateful to the authors who submitted original research manuscripts for this supplement and to the blinded scientific reviewers for their constructive feedback. We also thank the Medical Care staff, including Deputy Editor Hector Rodriguez and Managing Editor Karen Doyle for their scientific and technical guidance and logistical support.
