Goal of today’s talk
• Patient Navigation to address health
disparities
• Why community participation in patient
navigation research was critical to its
success
• What are the important health issues for
Asian American women today?

General Framework of Patient Navigation
• Abnormal finding/diagnosis
to resolution
• Eliminate critical delivery gap
for populations experiencing
disparities

• Is there a subset of
patients who
benefit?
• Can we determine
who benefits a priori
• Reduce resources for
the same benefit
Who benefits the most from navigation?
• Navigation eliminated the gap for these
vulnerable populations
▫ Low income
▫ Unmarried
▫ Unstable housing
▫ Unemployed
• Navigation also benefited those with:
▫ Multiple health care problems
▫ Social and legal barriers to care
Why was patient navigation
successful?
• Partnership between the research team
and community stakeholders
What is Community Based
Participatory Research (CBPR)?
• A true community-academic partnership
• Goal of improving health in the
community
Community Based Participatory Research
• Asks the right questions
• Advises on methods
that will work
• Interprets the findings
based on knowledge of
community
• Uses the findings to
benefit the community
Researchers

Community
members
How was CBPR critical to success of
patient navigation?
• Helped understand barriers to care
• Aligned important stakeholders to help
• Helped design a study that could be
completed in multiple community health
centers
• Once the results were in, we worked
together to find resources for ongoing
support
What do investigators need to do?
• Ask questions
• Support the community efforts in the
research
▫ Provide resources once the research is
funded
• Ask for help to interpret the findings
• Use the stakeholder group to
disseminate results
Asian Health Disparities in Women today
• What are the important health
questions?
Boston’s Chinatown
Cancer leading cause of
death among Asian
American women
Breast Cancer most
common cancer in
Chinese American
women
Fifth largest Chinese
population
Most densely settled
neighborhood
56% foreign born
62% linguistically
isolated
High rates of liver and
stomach cancer
Asian Cancer Disparities
• Foreign born Asian
populations have the
greatest unmet needs
during cancer care
• Foreign born Asian
populations have
greater
miscommunication
about goals of cancer
treatment
Asian Diabetes Disparities
• More diabetes,
metabolic diseases
at lower weight
▫ Overweight and
obesity redefined
for Asian
populations
Asian Mental Health Disparities
• Least likely to be screened for depression
• Present with physical symptoms
• Although patients understand their
symptoms to have emotional cause, less
likely to receive treatment
Asian Health Disparities
• Challenge of heterogeneity
• One size does not fit all
• Different challenges for different sub
populations
• Barriers to care often greater in foreign born
Asian American women
• Disease risks may or with place of birth
What we hope to gain today
• Community perspective
▫ Important health needs among Asian
American women
▫ Challenges
▫ Solutions
• Academic perspective
▫ Interventions to test solutions
▫ Methods to evaluate the interventions
