Journal of Ambulatory Care Management: April/June 2018 - Volume 41 - Issue 2 - p 128-137 doi: 10.1097/JAC.0000000000000227 Buy Metrics Abstract Urgent care centers have been identified as one means of shifting care from high-cost emergency departments while increasing after-hours access to care. However, the episodic nature of urgent care also has the potential to fragment care. In this study, we examine the adoption of 2 coordination activities—referrals and the electronic exchange of health information—at urgent care centers and other ambulatory providers across the United States. We find that setting is significantly associated with both health information exchange and referrals. Several organization-level variables and environment-level variables are also related to the propensity to coordinate care. © 2018 Wolters Kluwer Health, Inc. All rights reserved.
