• Systemic Factors and Access1
– Policies
– Insurance status
– Management protocols
– Data systems and EHRs
– Triage
– Accessibility of referrals
Background
Haider et al. JACS 2013; 216(3):482-92.
3. CENTER FOR SURGERY
AND PUBLIC HEALTH
Background: Systemic Factors Review
• Odds of death associated with SES after six high-risk surgeries in
nationwide Medicare population were diminished after controlling for
procedure volume.2
• Odds of death after blunt trauma 22% higher in African Americans,
33% higher in Hispanics, and 77% higher in uninsured.3
• Racial minorities and uninsured are less likely to receive counseling
about renal transplantation, be waitlisted for transplant, and receive
dialysis by fistula while waiting.4,5,6
4. CENTER FOR SURGERY
AND PUBLIC HEALTH
Background: Access Review
• Direct surrogates of access:
– Operation vs no operation in lung/cervical cancer resections7,8
– Delays in presentation in perforated appendix9
– Diagnosis-to-treatment time interval in breast cancer resection10
– Access to high-volume providers and centers2,11,12
• Procedural circumstances:
• Emergent vs elective care in ventral hernia repairs13
• MIS vs open techniques in appendectomy, gastric bypass14
• Outpatient vs inpatient procedures in mastectomies15
5. CENTER FOR SURGERY
AND PUBLIC HEALTH
Background: Access Review
• Appropriate procedure:
– curative intent vs palliative debulking in cervical cancer16
– breast conservation in breast cancer17
– Complete vs incomplete lymphadenectomy in GI resections18
– immediate vs interval cholecystectomies19
– limb salvage vs amputation in critical limb ischemia12
• Follow-up procedures:
• reconstruction s/p resection of breast cancer20
6. CENTER FOR SURGERY
AND PUBLIC HEALTH
Gaps in the Literature: Systemic Factors
• Effect of prospective clinical
interventions
– Culturally-sensitive patient navigation
improved colonoscopy screening 30%21
• Effect of Social determinants
– Community unemployment rates
correlate with (penetrating) trauma in
California22 and Louisiana23
– Trauma epidemiology in San Diego’s level
1 trauma center changed with national
policy on border fence height24
• Effect in very vulnerable groups
– Dual-eligibles, LGBT, undocumented
7. CENTER FOR SURGERY
AND PUBLIC HEALTH
Gaps in the Literature: Access
• Effect of policy
– Registration for simultaneous pancreas and kidney transplant
improved after Medicare coverage in 1999, but no change in
disparities25
– Receipt of MIS for appendicitis/cholecystitis improved after 2006
MA healthcare expansion for minorities, resolving disparities26
• Effect of management protocols
– Proportion of minority Medicare patients undergoing bariatric
surgery declined after CMS Centers of Excellence Program27
• Effect of adoption of technology
– Racial disparities in utilization of minimally-invasive prostatactomy
decreased during adoption between 2001-200728
8. CENTER FOR SURGERY
AND PUBLIC HEALTH
Future Directions
• NIH (NIMHD)29
– “the largest numbers of the medically underserved are White
individuals”
• IOM30
– “Lack of health care is a persistent barrier to good health”
• AHRQ31
– “across a broad spectrum of access measures, most
[disparities] did not improve”
9. CENTER FOR SURGERY
AND PUBLIC HEALTH
Conclusions
• Evaluate success of clinical programs in
overcoming systemic challenges
• Bridge gap between patients and providers: patient
navigators, m-health
• Improve communication: cultural competence, workforce
diversification
• Confront social determinants: residential segregation
• Policy-relevant access research
• Test the effect of management guidelines (i.e. adoption)
• Exploit natural policy experiments: MA reform, ACA DCP,
Medicaid expansion

Editor's Notes
-It goes without saying that there is overlap between ‘systemic factors’ and ‘access’, as shown in the diagram. The purpose of this talk is not to resolve those tensions, but rather to demonstrate the integrated nature of the problems.
-Policies can be at the institutional, healthcare system, or political level of nation/state.
-Management protocols include the strategies reflected in clinical guidelines.
-Triage (here) refers to the acute patient in emergency situations (i.e. protocols)
-Accessibility of referral pertains to the non-acute patient with regards to referrals and care management of chronic disease.
-In fact, the odds of death were no longer statistically significant in 3 of the 6 high-risk procedures. This reflects the underlying truth that socioeconomically-disadvantaged patients are more likely to seek care at low-volume (poor-quality) facilities.
-This demonstrates that race and insurance play independent roles (on multivariable analysis), even in emergency situations where care is driven by protocols and providers are likely to be unaware of insurance status. (i.e. not likely driven by provider bias)
-This shows that it is not one factor or issue but a panorama of missed opportunities for patients with kidney disease who systematically do not achieve optimal care when coordination of care is required through referrals.
Not mentioned:
-adjunctive care – medical therapies, post-mastectomy radiation
Effect of prospective clinical interventions: Over the last 15 years, the research community has become expert in reporting disparities but has only recently begun to rigorously evaluate prospective clinical interventions to reduce disparities. The literature must mature from a science of reporting problems to a science of evaluating solutions. As shown in the figure, one size will not fit all when it comes to equity.
Social determinants account for the overwhelming casual links to population health, whereas the healthcare system only accounts for approximately a quarter of the risk. (CDC website)
Effect of particularly vulnerable groups: Multiple high-risk groups have only recently emerged in the national spotlight as particularly vulnerable. These groups are difficult to study, and data is scant, but these particularly vulnerable groups must be a focus of future efforts to ensure equitable care for all.
Effect of policy: The list is short.
Effect of management protocols: The list is shorter.
Effect of adoption of technology: multiple studies report differential treatment with improved technologies (ie MIS vs non), but very very few studies have evaluated the rate of change over time in the context of Gaussian adoption curves to find the appropriate balance between implementation and equity.
