As healthcare providers, one of our main goals is to provide quality care for our patients while minimizing their hospital stay. Length of stay (LOS) after a surgical procedure is a significant indicator of the quality of care provided. Shorter LOS has been associated with improved patient satisfaction and decreased healthcare costs. However, in April 2022, we were alerted to a change in our typical LOS metrics. Between Jan 1 and Dec 31, 2021, our institution experienced increased LOS rates for two types of vascular surgery procedures: asymptomatic carotid endarterectomy (CEA) and endovascular aortic aneurysm repair (EVAR).

We next began a several month-long deep dive into our data to better define and understand the problem. Our analysis showed that 67% of SHC patients who underwent asymptomatic CEA had a postoperative LOS >1 day, while 36% of patients undergoing EVAR had a postoperative LOS >2 days. These rates were above the regional and national benchmarks set by the Vascular Quality Initiative (VQI) and had increased from prior years at SHC. As a team, we recognized the need to address this problem and focused on reducing LOS for these two procedures to meet our quality standards.

One of the strengths of our team was our strong cohesiveness, which fostered an environment of open communication and idea sharing. Our group consisted of a resident, APP, nursing educator, patient care manager, and case manager, providing a diverse set of perspectives. We spent a significant amount of time analyzing the data from the past two years and reviewing the system breakdowns before implementing interventions.

During our analysis, we discovered a breakdown in the system that contributed to the increased LOS rates. We targeted these gaps and implemented interventions to improve discharge planning moving forward. However, what surprised us was that the data analysis for our most recent patients showed that our “problem” may have slowly fixed itself. Nevertheless, we continued to implement interventions to sustain this positive change.

Our weekly Friday team meetings kept us accountable, and each team member took the initiative to research and implement interventions after the team had discussed them. Below are some examples of the changes to the discharge planning process that our team implemented:

  • Including an expected discharge time and date in the surgery scheduling letter that is mailed to patients ahead of surgery (similar to a “discharge appointment”)
  • Instituting a discharge screening tool the morning of surgery and documenting the results in the patient’s Epic chart, allows all providers to see if there are potential barriers to discharge before surgery starts.
  • Educating all key patient stakeholders including nurses, physicians, APPs, case managers, and PT on expected discharge procedures and length of stay.

Through these interventions, we were able to reduce the LOS  for CEA and EVAR. Accordingly, the percent of patients with LOS >1 day for CEA decreased from 50% to 43%, and LOS >2 days for EVAR decreased from 26% to 0%. 

In conclusion, our project aimed to reduce LOS for elective CEA and EVAR patients at our institution. We recognized the need to address this problem and worked together as a team to analyze the data, identify system breakdowns, and implement interventions to improve the discharge process for our patients and providers. Our efforts paid off, and we were able to sustain a positive change. As healthcare providers, it is important to monitor both our patient outcomes and existing systems and workflows to identify areas for future improvement.

Brian T. Bateman, MD, MSc is the Stanford Medicine Professor of Anesthesiology, Perioperative and Pain Medicine and Chair of the Department of Anesthesiology, Perioperative, and Pain Medicine.

Before coming to Stanford, Dr. Bateman served as the Vice Chair for Faculty Development and Chief of the Division of Obstetric Anesthesia in the Department of Anesthesiology, Perioperative and Pain Medicine at the Brigham and Women’s Hospital/Harvard Medical School and as Co-Director of the Harvard Program on Perinatal and Pediatric Pharmacoepidemiology in the Division of Pharmacoepidemiology and Pharmacoeconomics, Department of Medicine, Brigham and Women’s Hospital.

Dr. Bateman’s scholarship focuses on the study of medication safety in pregnancy and on predictors and management of maternal morbidity. To address questions in these areas, Dr. Bateman and collaborators at Harvard helped pioneer the use of advanced epidemiological techniques applied to large, routinely collected healthcare utilization data. This research has been funded by multiple R01 grants from the NIH and by grants from the FDA and has been published in leading clinical journals including JAMA, NEJM, BMJ, Lancet, Annals of Internal Medicine, JAMA Pediatrics, JAMA Psychiatry, and Obstetrics and Gynecology. Dr. Bateman’s bibliography contains over 200 publications. This research is frequently cited in clinical reviews and guidelines and has prompted both the FDA and EMA to make labelling changes to medications regarding use in pregnancy. Dr. Bateman is also a founding member of the International Pregnancy Safety Study Consortium (InPress) which is a collaborative effort between investigators from the US and each of the five Nordic countries to pool data for studies evaluating the safety of medications.

Dr. Bateman currently serves as Chairperson of FDA’s Anesthetic and Analgesic Drug Products Advisory Committee after having previously served a 4-year term (2015-2019) as a voting member of this Committee. He was a technical advisor for the recent revision of the Joint Commission’s pain management standards. He has served on expert panels and workshops sponsored by the National Academy of Medicine, the FDA, the NIH, the CDC, and the Department of Health and Human Services, and on multiple grant review committees for the NIH and other funders. He is an Editor for the journal, Anesthesiology, and the textbook, Chestnut’s Obstetric Anesthesia: Principles and Practice.

Dr. Bateman’s work has been recognized by a number of awards including his selection in 2017 by the Society for Obstetric Anesthesia and Perinatology as the Gerard Ostheimer lecturer and in 2018 by the American Society of Anesthesiologists as the James E. Cottrell Presidential Scholar Awardee, which is given to one clinical-scientist each year within 10 years of initial faculty appointment for accomplishment in research.

Faculty development and mentorship has been a central focus of Dr. Bateman’s career. He has mentored numerous trainees who have gone on to outstanding academic careers. As Division Chief and Vice Chair for Faculty Development at the Brigham, he worked particularly hard to advance the careers of women and underrepresented minorities in the Department and to create an environment where everyone is welcomed and has an opportunity to advance.

Dr. Bateman is a Phi Beta Kappa graduate Yale College and received his MD from Columbia University College of Physicians & Surgeons, where he was a member of Alpha Omega Alpha and was awarded the Janeway Prize for the highest achievements and abilities in the graduating class. He completed an internship in internal medicine at Brigham and Women’s Hospital and residency and chief residency in anesthesiology at the Massachusetts General Hospital. He completed a Masters in Epidemiology at the Harvard School of Public Health.
