Brain Reward Pathways

•The VTA-nucleus accumbens pathway is activated by all drugs of dependence including alcohol
•This pathway is important not only in drug dependence, but also in essential physiological behaviors such as eating, drinking, sleeping, and sex

Pathways for interactions among levels:
Social groups composed of individuals
Individuals composed of physiological
systems
Physiological systems composed of cells
Cells composed of molecules (DNA)
Only 1 in 10 people who use illicit drugsbecome
dependent on them
Genetic susceptibility to complex disease
usually results from joint effects of many genes,
each with a small to moderate effect and often
with interaction among themselves (e.g.
regions) and the environment.

Lower heart rate variability Slow recovery from exercise Elevated cortisol levels related to
accelerated cell aging Greater risk of metabolic syndrome Effects on hormonal regulation
(hypothalamic-pituitary-adrena axis) Increased risk for depression
Although there are (temporary) exceptions, such as the immigrant paradox, having better income and education is protective against most diseases and mental illnesses in the U.S.
Paradox affects weathering over time and immigrants have similar disability and chronic disease levels as U.S. born
Reasons: more persistent life stress, fewer resources available for avoiding impact of personal problems and unhealthy behaviors

Females: Alcohol Abuse/Dependence Rate by Parental Risk, Nativity, Time in Country, Age, and Language Preference
Only 3 subgroups show any effect of parental risk factors:• Female US born English all or most (high acculturation): 20% vs 2% (p < 0.001),• Female US born Spanish/English (low acculturation): 10% vs 2% (p = 0.04).• Female immigrant 13+ y Age 18–44 Spanish/English (high acculturation): 9% vs 2%

Every system is perfectly designed to achieve
exactly the results it gets.

“The First Law of Improvement” from Donald
Berwick
Access to care in a cost-control environment
Reconfiguring a fragmented health care system
Poor coordination of payers to providers for safety net populations
Low visibility and high stigma of mental health providers and treatments
Low availability of linguistically competent staff or translators
Low availability of co-ethnic specialists
Most mental health problems presented in primary care where behavioral health specialists are not available and providers are not disposed to offer treatment
Current levels of practicing mental health professionals: 29 Hispanics per 100,000 vs. 173 European Americans per 100,000

Spanish-speaking Latinos less likely to have physician visits, flu shots, or mammograms than English speaking Latinos or non-Latino whites. (Fiscella)
Children whose parents speak Spanish less likely to have usual source of care than English speaking Latinos or non-Latino whites. (Weinick)
Spanish speakers who could not communicate with their physicians less likely to be discharged from the ER with a follow-up appointment. (Sarver)
Fiscella K, Franks P, Doescher MP, Saver BG. Disparities in health care by race, ethnicity, and language among the insured. Med Care 2002;40:52-9.
Spanish speakers less likely to be discharged from the ER with an understanding of their medications, special instructions, and plans for follow-up care (Crane)
Spanish-speaking Latinos more likely to report problems with communication than English-speaking Latinos (Commonwealth Fund 2002 Health Care Quality Survey)
Spanish speakers who needed but didn't receive an interpreter were at much higher risk for not understanding discharge medications. (Andrulis in toolkit/Appendix A)
Crane JA. Patient comprehension of doctor-patient communication on discharge from the emergency department. J Emerg Med 1997;15:1-7.
Speaking a primary language other than English was an independent predictor of patient-reported drug complications. (Ghandi)
Spanish speaking patients less likely to receive standard of care (prompt surgery) in cholecystitis. (Diehl)
Ghandi TK, Burstin HR, Cook EF, et al. Drug complications in outpatients. JGIM 2000;15:149-154.
Patients whose primary language was not English significantly less likely to want to return to same ER for future care (Carrasquillo)
Patients who needed but didn't receive an interpreter in the ER were less satisfied with the care they received, as well as less satisfied with their physician. (Baker)
Carrasquillo O, Orav EJ, Brennan TA, Burstin HR. Impact of language barriers on patient satisfaction in an emergency department. JGIM 1999; 14: 82-87.
Pediatric patients with a language barrier had higher charges ($38) and longer stays (20 min) than those without language barriers. (Hampers 1999)
Pediatric patients who needed, but didn't receive, a professional interpreter had higher test costs and were the most likely to be admitted to the hospital (compared to patients who could speak directly with their doctors, and patients who had a trained interpreter). (Hampers 2002)

Repeated studies have shown that African Americans
tend to receive significantly higher doses of
antipsychotics than Caucasians
On the other hand, Hispanics and Asians seem likely to
receive lower antipsychotic doses than Caucasians
African and Hispanic Americans are more likely to
receive depot antipsychotics than Caucasians
African and Hispanic Americans seem more likely to
receive typical antipsychotics than Caucasians
