Reducing healthcare disparities in materially deprived patients Integrated Care Management Conference September 21-22, 2016 Presenter: Andrew J Knighton PhD CPA Intermountain Institute for Healthcare Delivery Research
Learning objectives Characterize current research on the effects of social determinants on healthcare outcomes Define an area deprivation index (ADI) and contrast its measurement qualities with other patient-reported measures of social determinants Discuss application of an ADI through a review of case studies at Intermountain Healthcare Identify potential future applications of an ADI in a healthcare context
Adversity is not randomly distributed: instead it tends to cluster and to accumulate present on top of past disadvantage David Blane, MD MSc
Social determinants and health People with a higher standard of living have better health outcomes (Marmot, 2006) The majority of health is driven by non-care delivery factors genetic, social, environmental, behavioral Social determinants of health include the factors that influence where we live, work, play and pray Countries with higher ratios of social-to-health spending have statistically better health outcomes (Bradley, 2013)
Linking social determinants of health with healthcare disparities Clinical outcomes/mortality (Kim, 2014) Higher levels of ED utilization (Tozer, 2013) Increased readmission risk (Kind, 2013) Delays in time to diagnosis and time to treatment (Gattrell,1998; McKenzie,2008; Dialla,2015) Medication adherence Engagement in shared decision making
Deprivation Material and Social Low High Material Social High The disadvantaged position of an individual, family, or group relative to the society to which they belong (Marmot) Deprivation can be material and social Material deprivation includes the lack of basic resources for living Social deprivation includes the lack of social support mechanisms Low
Deprivation Individual and Area Low High Individual Area High Deprivation can be measured at the individual level Deprivation can be measured at an ecological level based upon the effect of the environment or place Evidence that area deprivation impacts health independent of individual-level Deprivation measures can be: Compositional (aggregation of individual characteristics) Contextual (characteristics of place) Multi-level (combination) Low
Development of deprivation indices An area deprivation index is a geographic area-based measure of the disadvantaged position of residents relative to the society Used extensively in Europe, Australia and New Zealand Early measures compositional but have been evolving to include more contextual information Most common early measure is the Townsend Index proposed by Dr. Peter Townsend in 1988

Patient reported measures key Across the lifespan Quality of life Availability of social support Housing security Personal violence experience Episodic Physical functioning Pain
What is the Singh area deprivation index (ADI)? Index developed and validated by Singh (2003) based upon 17 census measures Education Employment Income Living Conditions Developed at the census block group level for the state of Utah (Knighton, et al 2016) Patient assigned an ADI score based upon the census block group they live in
Utah ADI results Frequency 0 10 20 30 40 50 60 Least Deprived 1 2 3 4 5-40 -30-20 -10 0 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 ADI score Most Deprived

Perceived barriers to healthcare for patients in poverty Living conditions Poor quality of interaction with providers Complexity of health system organization and functioning (Loignon, 2015)
Case study - Community Health Needs Assessment Non-profit hospitals conduct a triannual community health needs assessment (CHNA) Goal promote shared ownership of community health Strategic planning team established geographically based regions to evaluate socio-economic diversity Opportunity: used ADI to develop plans to address needs in more deprived areas
Case study High-risk patient identification for care management interventions Patients with higher deprivation are at increased risk of health complications and utilize more services Goal identify patients who need navigation support across health and healthcare services Community health programs evaluating use ADI in riskdetection algorithm Opportunity: improve identification of high risk patients who will benefit most directly from care management services

Case study Identifying patients most likely to benefit from a community-based program Need to develop partnerships between the delivery system and community programs Goal efficiently identify patients most likely to benefit from referral to community-based programs Implementing data-driven methodology to target highrisk patients most likely to benefit Opportunity: inform clinical judgement
Application of new criteria 1/3 rd of those currently being invited Double the odds of retention in the criteria population (OR 2.30 95%CI 1.05-5.05; p=.04). 19 women who were retained originally would not have been invited Data-driven approach informs clinical judgement does not replace it NFP Referral Clinical Workflow Practice Director OB/GYN Nurse Team Call Center/Scheduling Patient Institute for Healthcare Delivery Research Start Patient calls to schedule an appointment Call template completed Call template Nurse screening call completed within 7 days Screening call template No Yes Possible NFP eligible? Provide copy of completed screening call template Hard copy of screening call template Summarize results into a data file including EMPI, current address, age, payer type sent weekly 48 hour turnaround Generate ADI score for each patient and identify those meeting identified criteria First scheduled visit at 10-13 weeks Additional information included in patient evaluation Scheduled visit notes Incorporate into regular reporting to nurse team Possible NFP eligible report Referral Phase No NFP eligible based upon Stop visit? Yes Eligible candidates referred to NFP and Stop recorded Update listing of Stop referred patients Referred patients report
In Summary Research on the impact of social determinants of health on healthcare is developing ADI holds promise as a potentially useful surrogate measure of patient material deprivation when combined with other patient/family information More contextual work is needed to understand the conditions where additional intervention is needed Population-based solutions require the ongoing development of community-based partnerships in health
