Methods: The study sample consists of Veterans followed in geriatrics or primary care clinics at the Bronx and Indianapolis VAs who are older than 65. The investigators will monitor patients for non-VA hospital admission or ED visit using technology provided by regional HIE organizations (i.e., the Bronx Regional Health Information Organization and the Indiana Health Information Exchange). Patients will be cluster-randomized 1:1 to notification-plus-coordination or notification-only groups by PACT team, stratified by facility. For both groups the PACT provider will receive real-time notification of a non-VA hospital admission or ED visit if it occurs. For the notification-plus-coordination group, a care transitions coordinator will deliver coordination activities during a home and/or VA facility visit and via follow-up phone calls over 1 month. Coordination activities will consist of: reconciliation of and counseling on the patient's VA and non-VA medications, education on signs of condition worsening, coordination of VA and non-VA follow-up appointments, and counseling on communicating with VA and non-VA providers, using structured protocols. All information-gathering by the transitions coordinator will include the HIE as an information source. The notification-only group will receive usual care after the notification. Multivariable regression models will be estimated to compare effects of notification-plus-coordination versus notification-only on primary and secondary outcomes and costs (Aims 1 and 2). The investigators will conduct interviews with intervention team members, patients, VA and non-VA staff, and other stakeholders to ascertain the barriers and facilitators to implementation of these approaches (Aim 3).
