Abstract: OBJECTIVES: The aims of this study were to examine the relationship between external home help (EHH) use (ie, help provided by someone other than family or friends) and clinical response and patient-reported outcomes in patients with rheumatoid arthritis (RA), and to determine whether abatacept treatment in addition to methotrexate reduces the need for EHH. METHODS: EHH use was recorded monthly in the Abatacept in Inadequate responders to Methotrexate (AIM) trial, a 12-month, randomized, double-blind, placebo-controlled trial of abatacept in patients with active RA also receiving methotrexate. Clinical response was defined using American College of Rheumatology (ACR) criteria, European League Against Rheumatism (EULAR) criteria, and Disease Activity Scale (DAS)-28 score. Patient-reported outcomes included the Health Assessment Questionnaire (HAQ), 100-mm visual analog scales (VASs) for pain and fatigue, and the Medical Outcomes Study 36-item Short Form Health Survey (SF-36) for health-related quality of life. Analysis of covariance and regression analysis were performed to investigate the relationship between change in EHH use and both clinical response and patient-reported outcomes. RESULTS: Of 590 patients enrolled in the study, 232 (39.3%) were receiving EHH at baseline (mean age, 50.2 years; 88% female; 85% white; mean duration of RA, 8.8 years; mean [SD] EHH use, 15.6 [11.3] days). The level of EHH use was consistently higher with poorer scores on the HAQ, pain and fatigue VASs, DAS28, and SF-36. At 12 months, the mean reduction from baseline in EHH use was significantly greater in patients with ACR-50 or ACR-70 clinical response, EULAR good or moderate response, DAS28 remission, and clinically meaningful improvements in patient-reported outcomes. On multiple regression analysis, change in SF-36 Physical Functioning subscale score was the most important contributor to change in EHH after adjustment for other variables. The mean reduction from baseline in EHH use was significantly greater with abatacept compared with placebo over the study period (all, P<0.001). CONCLUSIONS: In this exploratory analysis of data from patients with active RA from the AIM trial, EHH use was decreased significantly with improvements in clinical response, disease activity, and patient-reported outcomes. Treatment with abatacept in addition to methotrexate was associated with significantly decreased EHH use, suggesting that abatacept may have been associated with improved function and increased physical independence in these patients with RA.
