Improving Decision-Making for Medications in Rheumatoid Arthritis (RA)

Background to Project-1
- Evidence-based consensus that early treatment with disease-modifying agents (DMARDs), including new biological agents, results in improved outcomes for RA.
- Project 2008-2010 to describe prevalence of problems in patient-physician communication in RA for vulnerable populations:
- Conducted at two UCSF sites: public hospital and tertiary hospital clinics.
- Observed clinically meaningful discordance between patients and physicians in assessment of disease severity.
- Found clinically and statistically significant differences in shared decision-making about treatments, disease severity, and functional status by race/ethnicity, language, and immigration status.
Background to Project-2
- Disparities in outcomes differed by site:
- Pronounced disparities at tertiary care setting, but almost none at public hospital clinic setting.
- Suggests the hypothesis that select features of public hospital clinic reduce disparities in communication, decisionmaking, treatments, and ultimately outcomes:
- Features include ....
- Translation services.
- Clinicians and staff with experience in multicultural care (including language).
- Clinicians and staff with experience in "working the system" for access to contemporary medications.
Examining Room as One Source of Disparity (But Not Only Source)

Background to Project-3
- Accumulating evidence that public sector clinical settings may improve treatment choices for vulnerable populations:
- Investigators found that quality of care for systemic lupus erythematosus may be substantially better in public managed care organizations.
- Trial designed to test one aspect of public hospital clinic's service mix for RA: communication about medication choices:
- Three arms:
- Existing RA Medication summary guide (from AHRQ).
- New RA Medication summary guide modified in consultation with members of vulnerable populations and rheumatologists.
- New RA medication summary guide plus decision aid tool to be used in clinical encounters.
Background to Project-4
- Outcomes assessed in trial....
- Knowledge about medications.
- Decisional conflict about medications.
- Assessment of interpersonal processes of care ("objective") and satisfaction with providers ("subjective").
- Treatment uptake for disease-modifying agents and side-effect profile.
- Disease activity and functional status at six months.
- Trial began last week with goal of 75 persons with RA in each arm.
- Criteria for enrollment:
- Member of vulnerable population based on one or more of following:
- Low health literacy, immigrant, elder, non-English speaker, non-white.
- Currently taking at least one disease-modifying agent.
- Currently active disease.
RA Treatment Trial and Framework for Evaluating iAdapt Projects
- All participants will be in targeted population (but we will monitor participation rate by category of vulnerability).
- Trial is really designed to see if health delivery system can overcome vulnerabilities brought to the ambulatory setting.
- Secondary goal of trial is to assess impact of summary guide and decision aid on outcomes (outcomes are multi-dimensional).
- Adoption, implementation:
- Will achieve adoption by FIAT given trial.
- Implementation snafus will be closely observed despite trial.
- Will measure outcomes at six months (but not primary outcomes of knowledge of and decisional conflict about medications).
Can You Bottle the Essence of a Clinic Focused on Vulnerable Populations?
- Prior project treated the two UCSF clinics as black boxes and found that one clinic was able to reduce disparities in access and outcomes.
- Current project "breaks into" the black box to test whether ability to communicate effectively about treatment choices is key element in improving outcomes in vulnerable populations.
- We will monitor implementation, but basically assume that we are operating in a lab, that is a clinic with an unnaturally small number of snafus dealt with in advance.
- RA may be good test of attempt to improve process of care since role of timely use of DMARDs has been proven effective and made the basis of treatment guidelines.
