Health Care Utilization Among Homeless Veterans in Chicago

Jason H. Raad, Elizabeth Tarlov, Abel N. Kho, and Dustin D. French

The VA does not capture health encounters that occur outside its facilities. Therefore, any analyses of health-care utilization will miss certain data; this is particularly important for at-risk populations, where understanding utilization will enable better and less fragmented care.  VA data was linked with Chicago’s HealthLNK Data Repository to find that of the 13,948 veterans who were homeless or at risk of becoming homeless, 17 percent of those veterans received some or all of their care in the community.

The Patient-Centered Outcomes Research Network (PCORnet) connects health systems, health plans, EHR data, and claims data to facilitate real-world clinical research. Datavant powers the linking of PCORnet. In this study, the authors looked to identify and understand the extent to which a clinical data research network and a health plan network contained consistent data on the patient level. Of the 549 patients from the EHR record who had claims with the health plan, sixty percent had consistent antibiotic exposure while 43.1% had a matched claims record.

Patients With Persistently Low MELD-Na Scores Continue to be at Risk of Liver Related Death

Nikhilesh R. Mazumder, Kofi Atiemo, Amna Daud, Abel Kho, Michael Abecassis, Josh Levitsky, and Daniela P. Ladner

Most patients with cirrhosis have low Model for End-Stage Liver Disease-Sodium (MELD-Na) scores. The ability for the MELD-Na score to predict patient outcomes at low scores remains unclear. The researchers were able to link data from across Chicago to understand what patients might be eligible; from there, 7922 patients were identified, with 3999 patients having low MELD-Na scores. Further analyses were performed to show that, though patients with high MELD-Na scores had higher rates of mortality and were more likely to die of liver-related causes, even patients with low MELD-Na scores had high rates of liver-related mortality.
