The study of error is not only in the highest degree prophylactic, but it serves as a stimulating introduction to the study of truth. --Walter Lippmann (1922)
Objectives • To (briefly) review of the literature on racial/ethnic disparities in pain-related healthcare. • To describe chronic pain characteristics that contribute to patient vulnerability to disparities in treatment and outcomes. • To review patient, provider, and environmental factors that occasion disparate care.

AHRQ National Healthcare Disparities Report:2000-02 vs. 2008-10 Quality of Care Indicators
Disparities in Pain Care: Multiple Conditions & Demographic Groups • Conditions • Low back pain (Tait et al., 2004) • Acute pain (Salmon & Manyande, 1996) • Recurrent pain (Elander et al., 2006) • Cancer pain (Cleeland et al., 1997) • Race/ethnicity • Todd et al., 1993; Green et al., 2003; IOM, 2003; Chibnall et al., 2005; Anderson et al., 2009; IOM, 2011; Meghani et al., 2012 • Gender • Martin & Lemos, 2002; Taylor et al., 2005 • Age • Old (Hadjistravropoulos et al., 2007; Weiner et al, 2002) • Young (Howard, 2003; Anthony & Schanberg, 2005) • Socioeconomic status • Morrison et al., 2000; Mayberry et al., 2000
Racial and Socioeconomic Factors in Disparate Care • Socioeconomic factors co-vary with minority status (Mayberry et al., 2000; Meghani et al., 2012) • Access • Analgesics (Morrison et al., 2000; Green et al., ) • Medical care (Meghani et al., 2012) • Insurance(Zuvekas and Taliaferro, 2003) • Resources(Tait & Chibnall, 2012)
Disparities in Occupational Lumbar Injury Outcomes Research (DOLOR)(Agency for Healthcare Research and Quality, R01 HS13087-01) • Missouri cases of LB injuries that were settled between 1/01 and 6/02 • St. Louis city, St. Louis county, Jackson county • 90% of African Americans in the state • 2,934 cases • 50.3% completed survey • 14.7% refused survey • 35.0% could not be traced • Data sources • WC database • Telephone survey instruments
Demographics(N = 1,475) • Age 43.6 years • Education = 13.07 years • Gender = 896 males, 533 females • Race (self-identified) = 889 Caucasian, 540 African Americans, 43 mixed, 3 refused • Working full-time at time of injury = 95.2% • Working full-time now = 62.8%
Predictors of WC Management:Demographics, SES, and Injury*(Tait et al., Pain, 2004) * Simultaneous entry multiple hierarchical regression: R2 change (all P’s < 0.001)
WC Database: Surgical vs. Non-Surgical Treatment(Chibnall et al., Spine, 2006) 2(1) = 106.1, P < 0.0001 OR = 4.0; 95% CI = 2.9 – 5.4
Claimants with HNP: Predictors of Surgery* • *No surgery vs surgery: 2(8) = 59.6, P < .001; R2 = 0.13 (N =640)
Clinical Outcomes: 2 Years Post-Settlement (Chibnall et al., Pain, 2005) * P < 0.0001
6-Year Follow-Up: High Levels of Pain, Catastrophizing, and Disability(Chibnall & Tait, Pain Medicine, 2011) * 1 = high (pain ≥ 7; PCS ≥ 30; PDI ≥ 45) vs. 0 = less than high
10 * 9.5 Caucasian 9 African American 8.5 8 7.5 7 6.5 6 5.5 Pct. Change from Baseline 5 * 4.5 * 4 * 3.5 * 3 2.5 * * 2 1.5 1 0.5 0 Baseline Year 1 Year 2 Year 3 Year 4 Year 5 Post-Settlement Years Race Effects on Financial Court Actions: 5 Years Post-Settlement(Tait & Chibnall, Spine, 2012)
Implications for Race & SES • Race/ethnicity and SES are associated with differences in patient/provider approach to treatment and intermediate-term outcomes • Race/ethnicity appears to account for greater effect during active clinical management • Race/ethnicity and SES are associated with differences in long-term outcomes • SES accounts for greater long-term effects • What accounts for disparate clinical management?
Judging Pain in Others: A Projective Test? One Patient Two Providers Opinion #1 Opinion #2
Acute Pain as symptom Biologic utility Anxiety Opioids OK Low addiction potential Pathology recognized Cure likely Chronic Pain as disease Little utility Depression Opioids problematic Poly-addiction potential Pathology unclear Cure often not possible Distinctions between Acute and Chronic Pain
Glasgow Illness Model(Adapted from Waddell et al., Pain, 1993) Sick Role Illness Behavior Psychological Distress Attitudes & Beliefs Pain/Illness
Internist Judgments of Chronic Low Back Pain(Chibnall, Dabney & Tait, Pain Medicine, 2000) • 48 internists from an academic school of medicine • 2 x 4 mixed between and within-subjects design • Vignettes describing hypothetical low back pain patients varied by pain severity (low vs. high) • Internists provided 4 waves of clinical information (history physical exam findings functional disability diagnostic test results) • Measures = MD judgments regarding patient medical/psychological/disability status, treatment, diagnostic testing, and referral options

High Pain Severity: Implications for Clinical Judgment Pain Report Low (1-3) Moderate (4-6) High (7-10) Little likelihood of context effects Some likelihood of context effects without objective evidence High likelihood of context effects with/without objective evidence
The Patient (“The Target”): Characteristics that Influence Judgments
Patient Factors that Influence Judgments • Chronicity • Klein et al., 1982; Teske et al., 1983; Taylor et al., 1984; Leclere et al., 1990; Eccleston et al., 1997; Hahn, 2001 • Distribution • Ransford et al., 1976; Von Baeyer et al., 1983; Margolis et al., 1986; Tait et al., 1990 • Behavior • Prkachin et al., 1994; Krause et al., 1994;Solomon et al., 1997; Prkachin et al., 2001 • Demographic • Race/ethnicity • Age • Gender
Ethnicity as a risk factor for inadequate emergency department analgesia(Todd, Samaroo, Hoffman. JAMA, 1993) Sample: Hispanic and white emergency department patients with isolated long-bone fractures Hispanics more than twice as likely as whites to receive NO analgesic medication for pain.
The Context (“The Situation”):Characteristics that Influence Judgments
Factors that Influence Judgments: Situational Features • Compensation status • Hadler, 1994; Kennedy, 1997; Chibnall and Tait, 1999; Merskey and Teasell, 2000; Kappesser et al., 2006 • Medical evidence • Carey et al., 1988; Birdwell et al., 1993; Tait and Chibnall, 1994; Chibnall and Tait, 1995; Chibnall et al., 1997; Tait et al., 2006

The Provider (“The Judge”):Characteristics that Influence Judgments
Cognition in Intuition and Reasoning(from Kahneman, American Psychologist, 2003)
Key Constructs of Cognitive Miser • Tends to attribute behavior to personal disposition, not situational factors • Behavior “engulfs the field” (Heider, 1958) • Makes common use of stereotypes • Cognitive structures that represent simplified knowledge about a concept or type of stimulus • Facilitates “top-down,” conceptually driven information processing • Shapes expectations
Features of Stereotypes • Usually cued by visually prominent physical features • Commonly applied to attributes such as gender, race, SES, age, mental health, attractiveness • Operates on perceptions at earliest moments (i.e., expectancies) • Creates less complex concepts • Stereotype consistent information more easily remembered than inconsistent information • Encoding inconsistent information requires effort
Judging Pain: Physician Specialty(Tait et al., 2010) * P < 0.05; ** P < 0.001
Pain Management: A Social Transaction • Pain management is an interactive phenomenon • Social transaction (Craig et al., 2010) • Participative decision-making (Frantsve & Kerns, 2006) • Social contract (Kappesser et al., 2008) • Contract influenced by assumed roles (patient and provider) • Implied contractual demands of patients with severe, chronic pain • Fix me • At least help me—analgesic medications (opioids?) • Handle any regulatory implications • Assume long-term management (not cure) • Embrace high (ongoing?) time demands • Recognize the likelihood of associated psychological distress • Tackle disability-related sequelae • Manage sick role, litigation and other system issues • Treat likely co-morbidities • Prepare for high costs of care
Conclusions I: Pain management as Social Judgment • Judgments regarding pain assessment and treatment fit a (complex) social cognition model • Racial/ethnic stereotypes appear to operate in clinical encounter • Social cognitive influences are greatest when pain is severe and supporting medical evidence is lacking • Patient factors (e.g., race/ethnicity) susceptible to symptom discountingunder conditions of high pain severity • Pain management best viewed as a social transaction
Conclusions II: Strategies to Reduce Disparities in Care • Treatment guidelines/education may minimize errors in judgment • Evidence-based medicine? • Multidisciplinary approaches • Maximize sources of input • Distribute treatment burden • Lessen empathy influences • Multiple sources of information to reduce bias • Pain severity, pain distribution, pain behavior • Levels of pain-related disability • Psychological distress as modifying, not invalidating pain experience
