Research Interests

Dr. Lobb conducts translational research to improve adoption and implementation of evidence-based interventions by clinical sites and in community settings to improve the quality of health care services for vulnerable populations and to reduce inequities in population health. Her research has primarily focus on cancer prevention and control. Dr. Lobb is committed to using participatory methods that engage stakeholders throughout the research process.

Implementation of Patient Navigation in Rural Geographic Areas – Patient Perspectives
This study will use qualitative methods to investigate patients’ perspectives on services they received from health care organizations in rural southeast Missouri to assist them with completion of follow-up care after an abnormal mammogram. The study population includes women with abnormal mammograms who attended a Federally Qualified Health Center or Rural Health Clinic that participated in another study led by Dr. Lobb.

Understanding Variability in Success of Quality Improvement for Colonoscopy
This pragmatic implementation-effectiveness study called Strategies to Improve Colonoscopy (STIC), compares the effect of two implementation strategies, physician education alone versus physician education plus staff training and an implementation toolkit to adopt evidence-based practices for bowel preparation before outpatient colonoscopy (i.e. split-dose bowel preparation, low-literacy education, teach-back). Outcomes measured in this study include adoption of the evidence-based practices by colonoscopy staff, patient experience with education for bowel preparation, adequacy of bowel preparation and adenoma detection.

Developing Strategies to Implement Patient Navigation in Rural Areas – Organizational Perspectives
This mixed methods study will survey Federally Qualified Health Centers and Rural Health Clinics in southeast Missouri to estimate adoption of patient navigation to improve early detection of breast cancer and the organizational characteristics that predict adoption.  In-depth case studies will be conducted on a sample of organizations that responded to the survey in order to add depth and meaning to survey findings and learn how we can potentially modify organizational factors to increase adoption of patient navigation in rural health care organizations.

Evaluation of a Strategy to Strengthen Cross-sector Collaboration Between Local Public Health and Health Care in Evidence-informed Obesity Prevention
The purpose of this project was to evaluate a “goal integration” strategy to improve collaboration among public health and health care stakeholders in obesity and chronic disease prevention, with a focus on the opportunity posed by mandatory community health assessment requirements for health care organizations.

Concept Mapping: Community Planning to Reduce Inequities in Cancer Screening

This was a one-year, community-engaged project that was Phase I of a multi-phase study to adapt evidence-based interventions to increase cancer screening among South Asians in Peel, Ontario (see link to community report on current webage). We used concept mapping to learn about barriers to use of mammograms, Pap tests, and fecal occult blood test for South Asians from the perspective of the community (e.g. residents, and representative representatives from health service and community service organizations) and identified the relative importance and feasibility to address each barrier within the next 2-3 years.
