Improving Early Detection and Treatment of Depression
Project Lead: Kristen Azar, RN, MSN/MPH, CHSR Principal Investigator, East Campus
The Challenge: Depression threatens the well-being of patients and their families, and is a significant cause of disability in the U.S. It is the most common mental health condition, but screening rates remain extremely low.
CHSR Approach: Leverage Sutter Health electronic health record (EHR) data to improve screening practices and ensure vulnerable patients receive timely care. CHSR researchers are using EHR data to better understand the real-world care practices of primary care providers around detection of depression during primary care visits, follow-up care, and treatment. The team will compare screened versus non-screened patients, and identify follow-up care in patients with depression. This study will be completed by December 2019.
The Impact: Results of this work will help improve the detection and treatment of depression in primary care. Early identification of depression may increase the effectiveness of treatment and reduce long-term effects on patient wellbeing and healthcare costs.

Joy of Work: Improving Physician Wellbeing
Project Lead: Ellis Dillon, PhD, Principal Investigator, West Campus
The Challenge: Over 50% of U.S. physicians report symptoms of burnout including depersonalization and/or emotional exhaustion.
CHSR Approach: Evaluate and understand factors comprising physician burnout, and support strategies to foster physician wellbeing across Sutter Health. Our team surveyed physicians from six Sutter-affiliated medical groups and explored changes over time. In 2018, 1,035 physicians (65%) completed the survey, and 842 commented on workplace changes that would significantly improve wellbeing.
We merged wellbeing survey responses from individual physicians with administrative data and data from electronic health records. We used statistical analyses to identify the factors significantly associated with burnout: having adequate support staff, finding work meaningful, feeling highly valued, and number of Epic in-basket messages received weekly.
Physicians’ written comments indicated they desired improved staff support, in-basket message support, decreased workload/improved work-life balance, progress note/documentation support, and improved leadership.e Impact: We are collaborating with Robert Nordgren, MD, Chief Executive Officer, Palo Alto Foundation Medical Group (PAFMG), and Suzanne Pertsch, MD, Director, PAFMG Office of Physician Wellness, to disseminate the findings and support efforts to enhance wellbeing.

Shining Light on Multiple Sclerosis With Precision Medicine: Floodlight Mobile
Project Lead: J.B. Jones, PhD, MBA, CHSR Principal Investigator, East Campus
The Challenge: Multiple sclerosis (MS) is a potentially disabling immunologic disease of the central nervous system. More than 2.3 million people have MS worldwide, including over 450,000 people in the U.S. Despite new research, the specific immunologic cause remains unknown and the disease has no cure. Most people with MS manage a relapsing-remitting course of the illness with disease-modifying therapies to slow disease progression. People with a less common form of the illness, called primary progressive MS, steadily decline in function.
Most neurologists see their MS patients once every six to 12 months. In each visit, it’s unlikely patients can convey a summary of their daily mobility experience and secondary symptoms with the precision needed to guide treatment decision making. So neurologists lack comprehensive data to deliver precise care.
CHSR Approach: We launched Floodlight™, a mobile application to leverage patient-generated data for new insights on MS progression in individual patients. Developed by Roche and pilot tested by Sutter Health, Floodlight™ collects patient data through digital questionnaires and online sensors that assess cognition, coordination and motor skills, mood, gait, and mobility in MS patients. We are collaborating with Sutter clinicians to design displays of the data that are clinically informative and actionable.
Approximately 100 Sutter Health patients will be recruited to test the mobile application; ongoing refinements through Summer 2019 will help ensure its use and validity in real-world settings.
The Impact: Floodlight™ will give neurologists meaningful, actionable patient data to help them provide more precise, personalized treatment to MS patients with varying disease subtypes.

Improving Early Detection of Lung Cancer
Project Lead: Jiang Li, PhD, MPH, CHSR Principal Investigator, West Campus
The Challenge: Lung cancer is the leading cause of cancer-related deaths in the U.S. Annual screening with low-dose computed tomography (LDCT-LCS) is recommended for heavy smokers and people at high risk for lung cancer.* Despite national guidelines on lung cancer screening, there is little data on the adoption of LDCT-LCS in large U.S. healthcare systems.
CHSR Approach: We launched the three-year Multilevel Study of Lung Cancer Screening Implementation (MUST) study. MUST filled critical knowledge gaps in the implementation of lung cancer screening and smoking cessation interventions, and identified multilevel barriers among patients and providers.
We compiled Sutter-wide electronic health record data from patients aged 55-80 years with no history of lung cancer who visited a primary care provider between 2010 and 2017. We studied implementation of LDCT-LCS and smoking cessation interventions, and multilevel factors associated with receiving a medical order of screening and counseling.
- Documentation of smoking history, smoking cessation interventions, and LDCT-LCS referrals increased since the U.S. Preventive Services Task Force recommended LDCT screening for lung cancer.
- Even after the policy implementation, only 7% of LCS-eligible patients were referred for LDCT-LCS.
- Lung cancer screening practice varied across primary care providers.
- Eligible patients seeing their regular primary care provider were significantly more likely to receive lung cancer screening referrals. Older, former smokers who had severe or moderate major comorbidities were significantly less likely to receive lung cancer screening referrals.
We are conducting in-depth interviews with patients and providers. Insights from our interviews will advance knowledge of patient and provider motivations and barriers for implementing LDCT-LCS and smoking cessation interventions.
*The National Lung Screening Trial demonstrated that, among individuals with a high risk of lung cancer, a 20% relative reduction in lung cancer mortality was observed with low-dose computed tomography for lung cancer screening (LDCT-LCS) compared to chest X-ray. In 2013, the U.S. Preventive Services Task Force (USPSTF) recommended annual screening for lung cancer with LDCT -LCS for heavy smokers aged 55-80 years. The guidelines included tobacco cessation interventions in parallel with LDCT-LCS. Despite these recommendations, there is little data on the adoption of LDCT-LCS in healthcare systems.

Improving Lynch Syndrome Screening
Project Lead: Su-Ying Liang, PhD, CHSR Principal Investigator, West Campus
CHSR Approach: We launched a collaborative, multi-site study to understand and compare decision making in Lynch syndrome screening across healthcare systems. The study includes clinical sites with diverse patient populations in various stages of implementing Lynch syndrome screening. Participating sites are: Sutter Health (Palo Alto Medical Foundation), Geisinger, Kaiser Permanente (Colorado, Northwest), Meyers Primary Care Institute, HealthPartners, Harvard Pilgrim Health Care, and Catholic Health Initiatives.
We interviewed patients and providers and used qualitative comparative analyses to identify barriers and facilitators of Lynch syndrome screening. Economic evaluation models were applied to investigate how contextual factors impact organization costs and program success. The five-year study is nearing completion of its second year (8/1/2017 – 7/31/2022).
The Impact: Study findings will advance understanding of how contextual factors impact Lynch syndrome screening across healthcare systems.

Improving Migraine Management with Mindfulness: A Pilot Trial
Project Lead: Alice Pressman, PhD, MS, CHSR Co-Director, Principal Investigator, East Campus
The Challenge: Migraine headache is one of the most common neurological disorders and a leading cause of disability worldwide. Medications are typically the standard therapy, but are only moderately effective and cause side effects; newer, more effective medications are expensive.
CHSR Approach: We investigated the effectiveness of Mindfulness-Based Stress Reduction (MBSR) in patients with moderate-to-severe migraine. MBSR has demonstrated clinically meaningful benefit in several chronic-pain syndromes and has shown promising results for migraine therapy in small case series and pilot studies.
We conducted a pragmatic* two-arm randomized controlled pilot trial of MBSR for the treatment of moderate-to-severe migraine. Our recruitment goal was approximately 60 participants with moderate-to-severe episodic migraine. The feasibility outcomes included ability and time required to recruit, adherence to the MBSR treatment, and demonstrated ability to measure outcomes. The active intervention consisted of an eight-week community-based mindfulness-based stress reduction (MBSR) class plus usual care, and the wait-list control group was usual care alone.
We recruited 66 participants; seven (11%) withdrew before the intervention began (six in the MBSR arm). Adherence to MBSR was high. Of the 28 who registered for MBSR, 26 (93%) attended at least five classes. We measured headache days and collected four-month questionnaire data on 50 (76%). We are analyzing the questionnaire data to understand participant experience with MBSR to help design the fully-powered trial.
The Impact: To our knowledge, this is the first pragmatic trial of MBSR for migraine in the U.S. It provided an excellent background for the design and implementation of fully-powered trials to determine the effectiveness of MBSR for reducing headache frequency in patients with moderate-to-severe migraine. The results will help us design and conduct a fully-powered, multi-center trial at Sutter Health in collaboration with Kaiser, UC San Francisco, and Stanford.
*Pragmatic trial in this case is defined as a trial that is designed to evaluate the effectiveness of an intervention under real-life routine practice conditions, as opposed to an explanatory trial which aims to test whether an intervention works under optimal conditions. In this case, the intervention was a broadly-available community MBSR class.

Improving Patient-centered Communication in Primary Care
Project Lead: Cheryl Stults, PhD, Principal Investigator, West Campus
The Challenge: Research suggests patients rarely talk openly with care providers because they fear retribution or being labeled ‘difficult’. On the ‘flip side’, healthcare providers are sometimes unprepared to answer all questions posed by their patients.
CHSR Approach: We launched the Open and Ask study to improve patient-centered communication in primary care.* We compared three interventions that empower patients to communicate honestly and that enable physicians to respond effectively: Open Communication High Touch, Open Communication High Tech, and ASK. The interventions are being tested at the University of California at San Diego, Sutter Health, and Reliant Medical Group in Massachusetts.
The four-year study will conclude in March 2021.
The Impact: The interventions are randomized at the clinic level to one of three communication approaches:
- Open Communication High Touch — Patients use an electronic system (MyHealthOnline) to prepare for office visits and communicate with their doctors through a questionnaire assessing health concerns. Doctors receive in-person training on how to discuss what matters most to patients.
- Open Communication High Tech — Patients use the Open Communication High Touch approach. Doctors receive training via a mobile app, versus in person.
- ASK — Clinics place posters in exam rooms that encourage patients to ask their doctors “What are my options? What are the possible risks and benefits of each option? How likely are the benefits of each option to occur to me?”
* This study builds on a previous pilot study conducted at the Palo Alto Medical Foundation of an approach called Open Communication. The study showed that patients and doctors who used open communication had better communication than patients who received standard care.

Machine Learning for Early Detection of Sepsis
Project Lead: Sylvia Sudat, PhD, CHSR Principal Investigator, East Campus
The Challenge: Sepsis — a potentially life-threatening condition caused by the body's response to an infection — is the leading cause of in-hospital mortality, and is associated with substantial healthcare costs. Early detection and treatment of sepsis is critical, yet its early symptoms are not easily detected.
CHSR Approach: We developed a predictive model identifying emerging sepsis using artificial intelligence and machine learning. This project leveraged in-hospital and ambulatory data from the Sutter Health electronic health record. The data will help summarize patients’ health at the time of hospital admission.
The Impact: Predictive modelling can help prevent sepsis-related complications and mortality among the 200,000 Northern California patients admitted to Sutter Health hospitals annually. Our project demonstrates how machine learning algorithms can be used to decrease U.S. healthcare costs and improve the care of patients nationwide.

Advancing Safe, Effective Opioid Prescription Stewardship
Project Lead: Sherry Yan, PhD, MS, Principal Investigator, East Campus
The Challenge: Addiction and deaths from opioid use pose an enormous public health burden across the U.S. Emergency departments (EDs) and urgent care clinics across Sutter Health face significant challenges to curb opioid over-prescribing.
CHSR Approach: We launched the Opioid Reduce Trial to promote opioid prescription stewardship. The randomized study will assess the change in opioid default pills count in electronic health records (EHRs), and the use of social comparison feedback to decrease opioid prescription pill burden in Sutter Health EDs and urgent care clinics.*
Opioid Reduce is a collaboration between Sutter’s Center for Health Systems Research, Sutter Information Services, William Isenberg, MD (Vice President, Office of Patient Safety, Sutter Health), and Howard Landa, MD (Vice President of Clinical Informatics and EHR, Sutter Health).
The Impact: Interventions (EHR default change and social comparison) in Opioid Reduce are designed to minimize interruption of clinicians’ workflow and represent real-world clinical settings. If we observe a successful intervention, we will scale it across Sutter Health, broadly disseminate findings, initiate further trials, and promote implementations nationwide.
*Default change describes an EHR function change where care providers set a default number of pills for medication.
