marginally significantP < .092
Increasing flare frequency was associated with marginally significant HAQ-DI (F=2.177, P < .092) and significantly greater mean HAQ-Pain (F=13.846, P < .001) as well as more PHQ anxiety (χ2=10.862, P < .012) and depression (χ2=7.061, P < .071). 15.5% reported past year ER/UC use, and 8.6% reported one or more hospital admissions, but neither was associated with flare frequency, perhaps due to the chronic and slowly progressive nature of IBM.
