2. OVERVIEW
Sources of Complexity
Examples of non-biological sources
The spider web framework
Barriers to managing complexity
3. Patient Complexity: not only Comorbidity Sources of patient complexity
Biological
Socioeconomic
Cultural
Environmental
Behavioral
Health care system must address ALL these sources to maximize health
4. Biological Complexity High patient variability in
Multiple comorbidity
Presentation of disease
Clinical course of disease/response to treatment
Existing evidence based guidelines generally do not handle this variability well
Because we lack the evidence
5. Socioeconomic Complexity: the Homeless Example Kertesz S, personal communication, 2007 ~ 400,000 Veterans experience homelessness each year
VHA spends ~ $1 billion/year serving homeless
~ $225 million in specific homeless services
Homeless (compared to housed) veterans are hospitalized
younger (by 10-18 yrs for medical/surgical dxs)
more for psychiatric and substance abuse diagnoses (80% vs. 29%) Adams J, J Health Care Poor Underserved 2007
With more recurrences of lower extremity cellulitis Lewis SD, Am J Med Sci 2006
More frequently when HIV + Gordon AJ, Med Care 2006
6. How does VA address Homeless Complexity? Examples Housing & Mental Health programs predominate
e.g. HUD-VASH: RCT of housing vouchers vs no vouchers embedded in 19-site roll-out of supported housing (1992)
Better housing & addiction outcomes Rosenheck. R, Arch Gen Psych 2003; Cheng, J Nerv Ment Dis 2007
VA tends to couch homelessness as a Mental Health Service, BUT
Among ~27k mentally ill in HCHV only 42% recd Primary Care over 6 mos Desai, M Med Care 2003
Homeless Veterans appear to have medical needs met no more frequently or even less so than homeless non-veterans. Desai, Gen Hosp Psychiatry 2005 & Kushel, JAMA 2001
7. Other Examples of Robust VA Homeless Research Northeastern Program Evaluation Center
~90 peer reviewed papers since 1988
Eg: In prospective f/u (n= 6199 homeless), social security cash benefits not associated with increased substance abuse Rosen M, HSR 2006
Pilot of peer-assisted case management of mentally ill veterans Weissman EM, Community Ment Health J 2005
8. Cultural Complexity: an ExampleMcEachrane-Gross, BMC Complement Alt Med 2006 27 % of 264 Veterans with cancer/chronic pain reported CAM use: herbs, dietary supplements, chiropractice, massage, acupuncture, homeopathy
CAM use positively associated with belief that lifestyle contributes to illness (also education, income, non-VA insurance)
76% would use CAM if offered in VA
