Patterns of Survivors' Recovery Trajectories in the ICECAP Trial (POST ICECAP)

Outcomes in Alcohol-related Liver Disease: A Prospective Registry (HERALD)

The Financial Impact of Burnout and Mental Health on Hospitalist Turnover and the Contribution of Work Structures and Environment (WORKWISE)

The purpose of this study is to assess the relationship between burnout, poor mental health, and hospitalist turnover (defined as intent to leave, reduced clinical effort, or actual resignation) to understand the economic costs associated with hospitalist turnover and the attributable costs from burnout and poor mental health.

Left Atrial Appendage Exclusion for Prophylactic Stroke Reduction Trial (LEAAPS)

The LeAAPS Trial will evaluate the effectiveness of AtriClip® LAA Exclusion System placement to prophylactically exclude the left atrial appendage for the prevention of ischemic stroke or systemic arterial embolism. The trial will include subjects undergoing cardiac surgery who have not yet been diagnosed with atrial fibrillation but have risk factors for both atrial fibrillation and ischemic stroke. The trial is a prospective, randomized (1:1), blinded, event-driven trial design that will enroll approximately 6500 subjects at up to 250 global sites.

Effect of Local Steroid on the Psoas Muscle After Transpsoas LLIF on Postoperative Thigh Pain and Nuerological Complications Interbody fusion

The Effect of Local Steroid on the Psoas Muscle After Transpsoas LLIF on Postoperative Thigh Pain and Neurological Complications Interbody fusion is an effective treatment option to provide decompression and stabilization to a painful spinal segment with additional surface area for fusion to occur across the disc space. Lateral lumbar interbody fusion (LLIF) can be performed in a less invasive or minimally invasive approach through the psoas muscle (trans psoas), however, it is associated with hip flexor pain and weakness due to violation of the psoas during the approach to the disc space. Corticosteroids such as depo-medrol have previously been shown to provide relief of nerve and muscle pain when applied topically during lumbar decompression and other spinal procedures. However, while they are often used during LLIF procedures, no study has been performed to evaluate their use in decreasing hip flexor pain or weakness. The goal of this study is to determine the effects of a corticosteroid administered to the psoas muscle following a transpsoas LLIF on postoperative hip flexor weakness and thigh pain and numbness.

Past Research

RECOVER Trial

The NIH sponsored RECOVER trial, an observational study to understand the long-term effects of COVID-19, launched at SHC-TV in Sept 2022. The study is led by Dr. Minjoung Go in the division of Hospital Medicine along with sub investigators, Dr. Kathleen Jia in the division of Hospital Medicine, Dr. Jake Scott in the division of Infectious Diseases, and Dr. Orlando Quintero also in the division of Infectious Diseases. The study involves 3 study visits in the first year and then once yearly visits thereafter for 3-4 years. Blood tests, urine, vital signs/assessments will be done, and participants will receive a survey every 3 months.

TRACK COVID Public Health Surveillance Study

From November 2020 to March 2021, SHC Tri-Valley has served as a site for the TRACK study. Led by Dr. Jenna Bollyky, this public health surveillance study collects monthly nasopharyngeal swabs, blood draws and online surveys from adults living in the Bay Area. The goal is to understand how many people are currently infected with COVID-19, how likely it is someone will become infected, and the body’s immune response to the coronavirus and the duration of immunity. The study is funded by the Chan Zuckerberg initiative and is in partnership with UCSF. The study successfully enrolled 271 participants at SHC Tri-Valley for a total of 1329 visits.

NIH Adaptable COVID Treatment Trials (ACTT)

In response to the COVID pandemic, the first clinical trial launched at SHC-VC was the ACTT-1 trial. The trial was initially brought to Stanford University's main campus in Palo Alto by the Division of Hospital Medicine and principal investigators, Dr. Kari Nadeau and Dr. Neera Ahuja. SHC Tri-Valley served as a subsite to Stanford Palo Alto. As hospitalists based at SHC Tri-Valley, Dr. David Svec, Dr. Minjoung Go and Dr. Evelyn Ling served as the sub-investigators with support from the research team at the Stanford Center for Clinical Research (SCCR).

The NIH ACTT trial was one of the first large multi-site double blinded placebo controlled trials to evaluate treatments for hospitalized patients with COVID. The first arm of the trial enrolled 1062 patients (2 at SHC Tri-Valley) and showed that remdesivir shortened time to recovery and led to the FDA approval. It has now become the standard of care treatment for hospitalized COVID patients. (see https://medicine.stanford.edu/news/current-news/standard-news/stanfordvalleycareclinicaltrial.html). Dr. Ling was featured on NPR discussing the preliminary results (https://www.npr.org/sections/health-shots/2020/04/29/848034963/antiviral-drug-remdesivir-shows-promise-for-treating-coronavirus-in-nih-study).

Since the trial structure is adaptive, it has enabled other potential therapies to also be trialed in the study. The trial has completed two subsequent arms, evaluating the drugs, barcitinib and interferon. SHC Tri-Valley has enrolled 5 and 7 patients respectively in these arms. The fourth arm of the trial was completed in early 2021 evaluating the combination remdesivir + baricitinib and remdesivir and dexamethasone.

CAMOSTAT Trial

In May 2021, the first outpatient clinical trial, the Camostat trial, was launched at SHC Tri-Valley in partnership with Stanford University. The study evaluated the efficacy of camostat, a drug given to newly diagnosed COVID patients who did not need to be hospitalized. This study was part of the COVID-19 Outpatient Pragmatic Platform Study (COPPS) led by Dr. Manisha Desai and Dr. Julie Parsonet of the Division of Infectious Diseases at Stanford University. SHC-VC served as a sub sitefor this study. At SHC Tri-Valley, efforts were led by infectious disease physicians, Dr. Jake Scott, who served as the site PI and Dr. Orlando Quintero, who was the sub-investigator in partnership with SCCR. The study is currently on hold until further notice.

Medtronic ELLIPSYS Post Market Surveillance Study

The Medtronic Ellipsys Post Market Surveillance Study began recruiting patients at SHC Tri-Valley in November 2022. This study is led by Dr. Karthik Kasirajan of the Vascular Surgery department at SHC Tri-Valley. The purpose of this observational study is to evaluate the safety and effectiveness of the Ellipsys Vascular Access System in the creation of a native AV fistula via percutaneous access in dialysis patients.
