Among older VA patients who have Medicare coverage, 43% use both VA and non-VA (Medicare-covered) services. VA and non-VA providers are often uninformed about encounters, treatments and test results provided in the other system. The overall objective of this project is to examine the impact of VA provider notification of non-VA hospitalization or emergency department (ED) visit using electronic health information exchange (HIE), along with provision of post-hospital care coordination services. The investigators will examine the impact of these approaches on preventing hospital readmission, increasing provider follow-up, improving patient's self-knowledge, and preventing medication errors. The investigators will also examine the effect of these approaches on VA and non-VA costs. Finally the investigators will examine the acceptance of these approaches among VA and non-VA providers. The study sample will consist 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 health information exchange organizations. Patients will be assigned to enhanced or control treatment groups. For both groups the VA provider will receive an electronic notification of a non-VA hospital admission or ED visit if it occurs. For the enhanced group, a care transitions coordinator will deliver post-hospital coordination services during a home and/or VA facility visit and follow-up phone calls over 1 month. The investigators' analyses will compare effects of notification-plus-coordination versus notification-only on health care outcomes. 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.
