Regional Data Exchange to Improve Care for Veterans After Non-VA Hospitalization

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
Background: 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. In particular, the absent or delayed notification of a non-VA hospital encounter is a missed opportunity for the VA to provide post-hospital transitional care services that have been shown to be effective in preventing adverse events and hospital readmission after hospital discharge. Objectives: The overall objective of this project is to examine the effectiveness, cost, and implementation acceptance of VA provider notification of non-VA hospitalization or emergency department (ED) visit using electronic health information exchange (HIE), with or without provision of evidence-based post-hospital transitional care services. Specific Aim 1 is to examine the impact of these approaches on preventing hospital admission or readmission as the primary outcome, and, as secondary outcomes, increasing provider follow-up, improving patient's condition self-knowledge, and preventing medication errors after discharge. been shown to be effective in preventing adverse events and hospital readmission after hospital discharge. Specific Aim 2 is to examine the effect of these approaches on VA and non-VA costs. Specific Aim 3 is to examine the acceptance of these approaches among VA and non-VA stakeholders. 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).

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Hospital Readmission | Percentage of patients with VA and non-VA hospital admission or readmission 90 days after non-VA hospital or ED discharge (or, if the patient is not discharged home, 90 days after discharge home from a rehabilitation facility) | 90 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Scheduled Follow-up | VA follow-up visit with a VA provider (physician or nurse practitioner) within 30 days of non-VA hospital discharge or ED visit. | 30 days | 
| Number of High-risk Medication Discrepancies | The number of discrepancies in medications classified as high risk for hospitalized older adults, including opioid analgesics, insulin, non-steroidal anti-inflammatory drugs, digoxin, antipsychotics, sedatives/hypnotics, and anticoagulants based on medical record review and patient or caregiver interview 30 days after non-VA hospital discharge. | 30 days | 
| Care Transitions Measure Score | A measure of condition self-knowledge and transitional care quality from the patient's perspective is ascertained by patient or caregiver interview 30 days after non-VA hospital discharge. The investigators will use an adapted 3-item version which includes items such as: After I left the hospital, I had all the information I needed to be able to take care of myself with the response options strongly agree, agree, disagree, strongly disagree, and don't know. The investigators chose to use the 3-item rather than a 15-item version as the shorter instrument demonstrates excellent correlation with the longer version but with lower respondent burden. Unabbreviated scale title is 3-Item Care Transitions Measure and minimum value is 1 and maximum value is 12. Higher scores mean a better transition/outcome. | 30 days |
