Qualitative and Mixed Methods studies

In qualitative research, scientists gather in-depth data using individual and focus group interviews, observation, and other methods. Mixed methods research combines qualitative research with quantitative research, which can often help achieve deeper understanding of an issue. Our researchers apply qualitative and mixed methods approaches to a variety of content areas, including cancer survivorship, completion of recommended vaccine series, variations in care, and other health issues.

An In-Depth Interview Study of Immunization Providers in a Large Managed Care Organization to Understand Practice Patterns, Barriers and Facilitators for Administering the 3-Dose HPV Vaccine Series

The primary objective of this study is to identify immunization providers’ opinions on practice patterns, barriers and facilitators for Gardasil 3-dose regimen completion among those who initiated the Gardasil vaccine.

Focus Home

The overall goal of this mixed-method, phased evaluation approach is to document the successes, challenges, and lessons learned from implementation of the Focus Home ecosystem components, and to document the process and outcome measures for key system end-users including patients, family caregivers, and clinicians as the service, IT, and population management data analytical features of the ecosystem goes live over the next two years.

Optimizing care delivery, quality and outcomes for people living with dementia (PLWD) and their family

We currently do not have a coordinated, effective, and scalable strategy to meet the ongoing medical and social needs of persons living with dementia (PLWD) and their families in KPSC. The goals of this project are: 1) better understand the patterns of diagnosis and care for patients with dementia, mild cognitive impairment and memory loss to identify potential improvement opportunities and 2) to generate preliminary data towards testing an integrated home-based care model for PLWD and their family caregivers.

The Bariatric Experience Long Term (BELONG) II for Racial and Ethnic Minority Patients

Effective treatments for severe obesity are particularly needed in racial/ethnic minority populations. Rates of severe obesity are as high as 36% for middle-aged non-Hispanic black women compared to 16% for their white counterparts in the U.S. Research on bariatric weight loss outcomes among racial/ethnic minorities is limited. What evidence does exist suggests that black patients consistently lose less weight than whites over 2–3 years of follow-up. The evidence for differences between Hispanic and white or black bariatric patients is equivocal. Hispanic patients have been shown to lose more, less, or the same amount of weight as non-Hispanic black and white patients. Across studies, the disparities in % total weight loss vary from less than 2% to 10%. This variability is twice as much as the amount of weight loss considered clinically meaningful. This study will extend the work done by our team during the Bariatric Experience Long-Term (BELONG) study which addressed how self-reported behavioral, psychosocial, and perceived environmental factors predicted weight loss over 3 years following gastric bypass and sleeve. Patients (n = 1,975) were 41% Hispanic, 17% non-Hispanic black, and 37% non-Hispanic white. The proposed study will expand the work of BELONG by incorporating: 1) A focus on weight regain during 3-5 years after surgery; 2) measures shown to contribute to health disparities in severe obesity (vigilant coping style and internalized racism); and 3) innovative qualitative methods (photo-elicitation and ethnography) to understand the patient experience.

Understanding and supporting COVID-19 vaccine confidence among health care providers

The purpose of this mixed-methods study is to examine perceptions of COVID-19 vaccines among health care providers, willingness to receive and recommend COVID-19 vaccine, drivers of vaccine hesitancy, and needs for tailored interventions to support confidence in COVID-19 vaccines among health care providers and community members.
