Kaiser Permanente Researcher Profiles

Vincent Liu, MD, MS, is a research scientist at the Kaiser Permanente Northern California Division of Research. His work focuses on the intersection of sepsis, acute severe illness, informatics, and health care delivery with a goal of building towards a learning hospital system.

Dr. Liu is board certified in Internal Medicine, Pulmonary Disease, Critical Care Medicine, and Clinical Informatics. He received his undergraduate degree from the University of Pennsylvania and his medical degree from New York University. He completed his residency training at New York University Hospitals (Bellevue) and a chief residency at Memorial Sloan-Kettering Cancer Center. He also completed a pulmonary and critical care medicine fellowship and has master’s degrees in Health Services Research and Biomedical Informatics, both from Stanford University.

In addition to his clinical practice and research, Dr. Liu is also the Regional Director of Hospital Advanced Analytics in Kaiser Permanente Northern California.

    Sepsis on FHIR

    Overall goal is to define and refine the current epidemiology, clinical characteristics, and treatment practices in respiratory failure in late and moderately preterm infants. Specific aims are to determine that incidence and epidemiology of respiratory failure in neonates born 32-36 weeks of gestation between 2012 and 2017 in Kaiser Permanente Northern California facilities; describe disease severity and respiratory support by diagnostic category; describe use of surfactant replacement therapy; and assess the impact of surfactant replacement therapy on length of respiratory support, length of hospitalization, and respiratory outcomes in the first year of life.

    Understanding and Informing Early Hospital Antibiotic Prescribing for Potential Infection

    The goals of this study are to (1) examine temporal trends in early hospital antibiotic prescribing patterns over the past 5 years, to assess for unintended consequences associated with earlier antibiotics in severe sepsis/septic shock; (2) quantify the patient-level harm associated with receipt of unnecessary antibiotics; and (3) identify subsets of patients, discernable in real-time with high certainty, who benefit from immediate antibiotics, versus the subsets of patients for whom it is safe to delay antibiotics by 3 hours (thereby allowing time for rapid diagnostics, such as procalcitonin).

    Targeting Cardiovascular Events to Improve Patient Outcomes After Sepsis

    Sepsis is the most common illness leading to hospitalization in the United States, affecting more than 1 million Americans each year. While short-term mortality has improved over prior decades, sepsis survivors face numerous post-hospital sequelae that negatively impact long-term morbidity and mortality. Cardiovascular complications are among the most common reasons for re-hospitalization and death after sepsis, with approximately 1 in 3 severe sepsis patients experiencing a cardiovascular complication in the year after sepsis hospitalization. This project seeks to identify risk factors for post-sepsis cardiovascular risk based on granular inpatient data collected during hospitalization, and identify potential opportunities to reduce post-sepsis cardiovascular risk.

    Using EHR Audit Logs to Capture Diagnostic Pathways and Time to Diagnosis

    Rapid expansions in the use of electronic health record (EHR) systems also contribute to large expansions in the availability of metadata. These highly granular metadata may prove particularly useful for understanding how frontline clinicians interact with clinical information when making diagnostic decisions. This project aims to characterize EHR audit log data and advance nascent understanding of the potential to leverage these to provide novel insights into the diagnostic process, with a focus on time to diagnosis, and ultimately inform the achievement of diagnostic excellence.

    Identifying Pre-Sepsis Opportunities for Early, Targeted Intervention

    ​This project is designed to pursue pre-sepsis opportunities to identify patients at high-risk for sepsis and develop risk prediction models to mitigate the impact of impending sepsis by leveraging granular electronic health record data.

    Benchmarking Hospital Quality - Template Matching

    ​In this study, Kaiser Permanente Northern California researchers will serve as consultants for U.S. Department of Veterans Affairs (VA) researchers to evaluate the utility of template matching techniques, compared with standard regression techniques, for comparing hospital quality.

    Benefits of Intensive Care Unit Admission for Patients with Acute Respiratory Failure or Sepsis

    Ideal and optimally efficient use of intensive care unit (ICU) resources would create benefits across the health care system. Ideal use of ICU resources requires a needs assessment to determine which categories of patients commonly admitted to ICUs derive true net benefit on average from ICU admission versus admission to a regular hospital floor. This project aims to conduct such a needs assessment, which has never before been done.

    Data-Driven Precision Medicine in Sepsis

    Sepsis is a common and costly disease which contributes to nearly 1 in 2 hospital deaths in our healthcare system. While aggressive early treatment with quantitative resuscitation has demonstrated benefit, many other interventions have not demonstrated efficacy likely resulting from an incomplete understanding of sepsis disease mechanisms. This study seeks to address three questions through innovative approaches to using observational data: (1) what factors can improve our characterization and phenotyping of sepsis patients; (2) what are the potential benefits of using quantitative resuscitation in less severe sepsis subgroups; and (3) how does acute organ dysfunction impact long-term mortality and utilization among sepsis survivors
