  • Multicenter Phase II Study of Transanal TME (taTME)

    open to eligible people ages 18 years and up

    Radical rectal cancer resection, namely total mesorectal excision (TME), is the cornerstone of the treatment of resectable rectal cancer. In combination with chemotherapy and radiation treatment (CRT), complete TME with negative resection margins is associated with sustained local and systemic control even in locally advanced disease. Over the last 2 decades, laparoscopic and robotic techniques have been increasingly adopted due to reduced surgical trauma and faster patient recovery. Yet, both approaches are associated with equivalent postoperative morbidity and disturbances in sexual, urinary and defecatory function relative to open TME. Furthermore, laparoscopic and robotic TME remain associated with substantial conversion rates and variable rates of TME completeness as a result of the procedural difficulties reaching the low rectum from the abdominal approach. Transanal TME (taTME) with laparoscopic assistance was developed to facilitate completion of TME using a primary transanal endoscopic approach. Transanal TME uses a "bottom-up approach" to overcome the technical difficulties of low pelvic dissection using an abdominal approach. Published results from single-center taTME series and an international registry suggest the short-term procedural and oncologic safety of this approach in resectable rectal cancer. No multicenter phase II study has yet been conducted to validate the procedural safety, functional outcomes or long-term oncologic outcomes of this approach. Study Design: This is a 5-year phase II multicenter single-arm study to evaluate the safety and efficacy of low anterior resection (LAR) with taTME using laparoscopic or robotic assistance in 100 eligible subjects with resectable rectal cancer. Hypothesis: taTME is non-inferior to standard LAR with respect to the quality of the TME achieved.

  • Multimodal Analgesia Effect on Post Surgical Patient

    open to eligible females ages 35-65

    Patients undergoing Bariatric Surgery at the University of California Davis Medical Center will be divided into two groups, one receiving Standard of Care pain control medications vs the second group which will receive non-narcotic pain medications with rescue pain medications available if needed

  • Norepinephrine vs Phenylephrine During General Anesthesia

    open to eligible people ages 18-99

    50 million patients undergo surgery each year in the United States. Postoperative mortality is considered the third leading cause of death worldwide. Hypotension during surgery have been linked to increased postoperative morbidity and mortality. Episodes of hypotension during surgery are associated with an increased risk of acute kidney injury, stroke, cardiac events and death. Treating or preventing hypotension during general anesthesia and major surgery was found to improve outcomes. At this time, it is unclear what is the best vasopressor to maintain blood pressure during surgery under general anesthesia. With this pilot pragmatic trial, the investigators will explore the impact of norepinephrine (NE) or phenylephrine (PE) on post-operative events in patients undergoing major surgery with general anesthesia and needing vasopressors infusion to maintain their systemic arterial pressure.

  • Study to examine if video self review of intubation skills by medical students help them learn the skill faster

    “Video of medical students performing intubation on patients to aid in their education and competency of this skill”

    open to all eligible people

    This study is designed to evaluate the impact of a video recording review on the acquisition of a new technical skill (laryngoscopy and tracheal intubation).

  • Smarter Care Virginia

    Sorry, in progress, not accepting new patients

    Low-value care is defined as patient care that provides no net benefit to patients in specific clinical scenarios, and it can cause patient harm. Prior research has documented high-rates of low-value care in Virginia, and this work has helped to inspire a Virginia government-sponsored quality improvement initiative to reduce low-value care. Funded by a $2.2 million Arnold Ventures grant, six large health systems in Virginia volunteered to partner with the Virginia Center for Health Innovation (VCHI) to reduce use of seven low-value health services (three preoperative testing measures, two cardiac screening measures, one diagnostic eye imaging measure, and one peripherally inserted central catheter [PICC] measure). These health systems include nearly 7,000 clinicians practicing across more than 1,000 sites. VCHI is implementing a step-wedge cluster-randomized physician peer-comparison feedback quality improvement intervention to reduce the use of these seven low-value services. VCHI will provide education, quality improvement training, and financial resources to each site, and VCHI will use the Milliman MedInsight Health Waste Calculator to create the peer comparison reports using the Virginia all payer claims database (APCD). Of note, the primary purpose of the initiative is to improve quality of care for Virginia residents and this initiative is not being done for research purposes, and step-wedge randomization is done to both ease logistical workload on VCHI and clarify impact of intervention (IRB exempt). Nevertheless, University of California, Los Angeles (UCLA) team plans to rigorously study and publish the impact of this intervention across the state of Virginia, which is why the UCLA team is preregistering the initiative. The UCLA team will use the Virginia APCD to evaluate the impact of the intervention. Because the APCD has a 1 year time-lag of data collection, the initial results of the impact of the intervention will not be available until August 2020 at the earliest.
