Factors Associated with a Physician-Reported Medical Reason for Which Care Was Not Provided among RA Patients whose Physicians reported on RA Measure 108^*

	Adjusted** Odds Ratio (95% Confidence Interval) for PQRS Measure 108: Medical Reason why DMARD/Biologic Was Not Prescribed to RA Patient
Age (5 year increments)	1.08 (1.04 – 1.12)
Black race (referent to white)	1.44 (1.14-1.84)
Comorbidities (each row referent to not having the comorbidity)
Renal disease	1.83 (1.45 - 2.29)
COPD	1.19 (1.03 – 1.37)
Malignancy	1.54 (1.27 – 1.86)
Liver disease	3.06 (1.29-7.26)

^*the dependent variable modeled was whether the patient was given a medical reason (on the PQRS claim) for why a non-biologic or biologic DMARD or biologic was prescribed (n = 645 patients) referent to patients for whom the physician reported to PQRS that a non-biologic or biologic DMARD was prescribed (n =11,945 patients). Within-practice clustering was adjusted for using alternating logistic regression [14].

^**adjusted for gender, other racial/ethnic groups (asian, Hispanic, and others), dual eligible status, urban/rural residence, low income subsidy, and socio-economic status (defined by census block group). Also adjusted for diabetes, hepatitis C, HIV disease, heart failure, and treating physician age and gender, none of which was significantly associated with the outcome.
