Evaluation of a Novel Equity-Focused Intervention to Optimize Thiazide Dosing and Improve Blood Pressure Control among African Americans at KPNC (Q3’16 – Q4’17)

Principal Investigator: A Adams
Co-Principal and Co-Investigators: A Ferrara, J Young, N Thompson, E Kim, M Lin

In 2014, TPMG created a tool in Patient Management Tool to improve the ability of care teams to identity African Americans with poor blood pressure control who may benefit from thiazide diuretic initiation or intensification. This study addressed the following research questions: Did implementation of the new tool improve: 1) rates of clinically appropriate prescribing; 2) the proportion of black/African American members achieving adequate blood pressure control; and 3) the gap in blood pressure control between blacks/African Americans and white patients.

Optimizing Case Management Referral for Patients with Complex Chronic Conditions

Principal Investigator: Richard W. Grant, MD, MPH

Complex patients with chronic conditions are a costly and growing segment of the Kaiser Permanente Northern California membership. This study used novel data to provide a clearer understanding of the factors associated with optimal case management referral with the goal of improving the patient referral process.

Real-time Decision Support Algorithm for Pulmonary Embolisms in the ED

Principal Investigator: Mary E. Reed, DrPH

This study assessed the performance characteristics and feasibility of adding comprehensive patient clinical data from the Division of Research's Virtual Data Warehouse (VDW) to enhance the existing electronic pulmonary embolism clinical decision support tool used by physicians.

Hospital Medicine

Building a Data Pipeline for Treating Patients with Acute Respiratory Distress Syndrome

Principal Investigator: Vincent Liu, MD, MS

This study uses informatics approaches in multiple modalities to translate Electronic Medical Records data into improved diagnostic tools for physicians to use in the treatment of patients with acute respiratory distress syndrome.


Development and Testing of a Mobile-health (m-health) Intervention Tool to Help Obese Women Achieve Appropriate Gestational Weight Gain (Q2’16 – Q1’18)

Principal Investigator: M Hedderson
Co-Principal and Co-Investigators: A Ferrara, T Flanagan, S Mandel

This project aims to determine whether a mobile-health (m-health) tool intervention for obese pregnant women increases the proportion of obese women that meet the IOM gestational weight gain guidelines.

Phase 1 Case Series and Feasibility Study: Robotic Hysterectomy for Benign Gynecologic Disease

Principal Investigators: Lisa Herrinton, PhD, and Tina Raine-Bennett, MD, MPH

The long-term goal of this study is to test the hypothesis that women with complex benign disease will have better outcomes with robotic surgery than if these same women had received traditional minimally invasive surgery. 

The Relationship of Robotic Approach and Surgical Volume with Outcomes of Hysterectomy for Benign Gynecologic Disease (Phase 2) (Q2’16 – Q4’17)

Principal Investigator: L Herrinton
Co-Principal and Co-Investigators: T Raine-Bennet, S Alexeeff, W Ramos, B Suh-Burgmann

This study will provide a robust analysis of several outcomes questions related to the use robotic laparoscopic-assisted hysterectomy (RLAH) in patients with benign gynecologic disease, including relationship of disease complexity and surgeon factors with outcome.


Assessing Practice Patterns and Potential Quality Gaps in Pulmonary Nodule Evaluation

Principal Investigator: Lori C. Sakoda, MPH, PhD

The goal of this study was to assess practice patterns and potential quality gaps in evaluating patients with pulmonary nodules. Accurate and prompt clinical evaluation of whether a nodule is benign or malignant is critical, since survival is improved in patients when lung cancer is detected at earlier stages. 


A Mixed Methods Approach to Evaluating Autism Spectrum Disorder Interventions

Principal Investigator: Lisa A. Croen, PhD

This was a study of an evolving clinical program serving a diverse population of Kaiser Permanente Northern California members. Quantitative and ethnographic methods identified factors influencing participation and compliance with recommended services, and provided insight on the benefits of various treatments.


Population Management Reports

Principal Investigator: Lisa Herrinton, PhD

To accelerate care transformation, we need to increase the deployment of measurement systems and technology for population management and quality improvement. This study examined sharing knowledge in four categories: rapid reports, structured documentation, source data, and helping physicians scope quand it ality improvement projects.

Patient Experiences with Video Visits

Principal Investigator: Mary E. Reed, DrPH

Video visits can be a convenient, secure way for patients to meet with their doctor online, using a mobile device or computer. This study surveyed Kaiser Permanente Northern California members to understand patient experiences with video visits and with their health care providers.

The Delivery Science Rapid Analysis Program (Q2’ 16 - Q1 ’18)

Principal Investigators: J Schmittdiel
Co-Principal and Co-Investigators: R Dlott

The Delivery Science Rapid Analysis Program, created in 2013, provides a mechanism that prioritizes and addresses rapidly researchable analytic questions with high-value to both TPMG’s quality improvement initiatives and DOR’s research agenda.
