    (Springer, 2022-02-23) Boockvar, Kenneth S.; Koufacos, Nicholas S.; May, Justine; Schwartzkopf, Ashley L.; Guerrero, Vivian M.; Judon, Kimberly M.; Schubert , Cathy C.; Franzosa, Emily; Dixon, Brian E.; Epidemiology, Richard M. Fairbanks School of Public Health
    Background Health information exchange (HIE) notifications when patients experience cross-system acute care encounters offer an opportunity to provide timely transitions interventions to improve care across systems. Objective To compare HIE notification followed by a post-hospital care transitions intervention (CTI) with HIE notification alone. Design Cluster-randomized controlled trial with group assignment by primary care team. Patients Veterans 65 or older who received primary care at 2 VA facilities who consented to HIE and had a non-VA hospital admission or emergency department visit between 2016 and 2019. Interventions For all subjects, real-time HIE notification of the non-VA acute care encounter was sent to the VA primary care provider. Subjects assigned to HIE plus CTI received home visits and telephone calls from a VA social worker for 30 days after arrival home, focused on patient activation, medication and condition knowledge, patient-centered record-keeping, and follow-up. Measures Primary outcome: 90-day hospital admission or readmission. Secondary outcomes: emergency department visits, timely VA primary care team telephone and in-person follow-up, patients’ understanding of their condition(s) and medication(s) using the Care Transitions Measure, and high-risk medication discrepancies. Key Results A total of 347 non-VA acute care encounters were included and assigned: 159 to HIE plus CTI and 188 to HIE alone. Veterans were 76.9 years old on average, 98.5% male, 67.8% White, 17.1% Black, and 15.1% other (including Hispanic). There was no difference in 90-day hospital admission or readmission between the HIE-plus-CTI and HIE-alone groups (25.8% vs. 20.2%, respectively; risk diff 5.6%; 95% CI − 3.3 to 14.5%, p = .25). There was also no difference in secondary outcomes. Conclusions A care transitions intervention did not improve outcomes for veterans after a non-VA acute care encounter, as compared with HIE notification alone. Additional research is warranted to identify transitions services across systems that are implementable and could improve outcomes.

    Impact of event notification services on timely follow-up and rehospitalization among primary care patients at two Veterans Affairs Medical Centers
    (Oxford University Press, 2021-11-25) Dixon, Brian E.; Judon, Kimberly M.; Schwartzkopf, Ashley L.; Guerrero, Vivian M.; Koufacos, Nicholas S.; May, Justine; Schubert, Cathy C.; Boockvar, Kenneth S.; Medicine, School of Medicine
    Objective: To examine the effectiveness of event notification service (ENS) alerts on health care delivery processes and outcomes for older adults. Materials and methods: We deployed ENS alerts in 2 Veterans Affairs (VA) medical centers using regional health information exchange (HIE) networks from March 2016 to December 2019. Alerts targeted VA-based primary care teams when older patients (aged 65+ years) were hospitalized or attended emergency departments (ED) outside the VA system. We employed a concurrent cohort study to compare postdischarge outcomes between patients whose providers received ENS alerts and those that did not (usual care). Outcome measures included: timely follow-up postdischarge (actual phone call within 7 days or an in-person primary care visit within 30 days) and all-cause inpatient or ED readmission within 30 days. Generalized linear mixed models, accounting for clustering by primary care team, were used to compare outcomes between groups. Results: Compared to usual care, veterans whose primary care team received notification of non-VA acute care encounters were 4 times more likely to have phone contact within 7 days (AOR = 4.10, P < .001) and 2 times more likely to have an in-person visit within 30 days (AOR = 1.98, P = .007). There were no significant differences between groups in hospital or ED utilization within 30 days of index discharge (P = .057). Discussion: ENS was associated with increased timely follow-up following non-VA acute care events, but there was no associated change in 30-day readmission rates. Optimization of ENS processes may be required to scale use and impact across health systems. Conclusion: Given the importance of ENS to the VA and other health systems, this study provides guidance for future research on ENS for improving care coordination and population outcomes.

    Improving Patient Activation among Older Veterans: Results from a Social Worker-Led Care Transitions Intervention
    (Taylor & Francis, 2022) Koufacos, Nicholas S.; May, Justine; Judon, Kimberly; Franzosa, Emily; Dixon, Brian E.; Schubert, Cathy C.; Schwartzkopf, Ashley L.; Guerrero, Vivian M.; Traylor, Morgan; Boockvar, Kenneth S.; Medicine, School of Medicine
    Older veterans enrolled in the Veterans Health Administration (VHA) often use both VHA and non-VHA providers for their care. This dual use, especially around an inpatient visit, can lead to fragmented care during the time of transition post-discharge. Interventions that target patient activation may be valuable ways to help veterans manage complex medication regimens and care plans from multiple providers. The Care Transitions Intervention (CTI) is an evidence-based model that helps older adults gain confidence and skills to achieve their health goals post-discharge. Our study examined the impact of CTI upon patient activation for veterans discharged from non-VHA hospitals. In total, 158 interventions were conducted for 87 veterans. From baseline to follow-up there was a significant 1.7-point increase in patient activation scores, from 5.4 to 7.1. This association was only found among those who completed the intervention. The most common barriers to completion were difficulty reaching the veteran by phone, patient declining the intervention, and rehospitalization during the 30 days post-discharge. Care transitions guided by social workers may be a promising way to improve patient activation. However, future research and practice should address barriers to completion and examine the impact of increased patient activation on health outcomes.

    Regional data exchange to improve care for veterans after non-VA hospitalization: a randomized controlled trial
    (Biomed Central, 2019-07-04) Dixon, Brian E.; Schwartzkopf, Ashley L.; Guerrero, Vivian M.; May, Justine; Koufacos, Nicholas S.; Bean, Andrew M.; Penrod, Joan D.; Schubert, Cathy C.; Boockvar, Kenneth S.; Epidemiology, Richard M. Fairbanks School of Public Health
    BACKGROUND: Coordination of care, especially after a patient experiences an acute care event, is a challenge for many health systems. Event notification is a form of health information exchange (HIE) which has the potential to support care coordination by alerting primary care providers when a patient experiences an acute care event. While promising, there exists little evidence on the impact of event notification in support of reengagement into primary care. The objectives of this study are to 1) examine the effectiveness of event notification on health outcomes for older adults who experience acute care events, and 2) compare approaches to how providers respond to event notifications. METHODS: In a cluster randomized trial conducted across two medical centers within the U.S. Veterans Health Administration (VHA) system, we plan to enroll older patients (≥ 65 years of age) who utilize both VHA and non-VHA providers. Patients will be enrolled into one of three arms: 1) usual care; 2) event notifications only; or 3) event notifications plus a care transitions intervention. In the event notification arms, following a non-VHA acute care encounter, an HIE-based intervention will send an event notification to VHA providers. Patients in the event notification plus care transitions arm will also receive 30 days of care transition support from a social worker. The primary outcome measure is 90-day readmission rate. Secondary outcomes will be high risk medication discrepancies as well as care transitions processes within the VHA health system. Qualitative assessments of the intervention will inform VHA system-wide implementation. DISCUSSION: While HIE has been evaluated in other contexts, little evidence exists on HIE-enabled event notification interventions. Furthermore, this trial offers the opportunity to examine the use of event notifications that trigger a care transitions intervention to further support coordination of care.
