Treatment adherence in patients with rheumatoid arthritis and systemic lupus erythematosus.

This study assessed self-reported adherence in patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) from underserved healthcare settings. We conducted a cross-sectional survey of 102 ethnically diverse patients--70 with RA and 32 with SLE--attending rheumatology clinics at publicly funded hospitals in Houston, Texas; 43% were Hispanic, 32% African-American, and 25% White. Treatment adherence was evaluated using the compliance questionnaire rheumatology (CQR; 0, low adherence and 100, high adherence) and the questionnaire of the Adult AIDS Clinical Trials Group (AACTG). The patients were also asked how often they forgot to take their prescribed medications or discontinued them on their own. Mean patient age was 48.5 years; 75% were female, 32% were African-American, 43% Hispanic, and 25% White. Only one third reported never forgetting to take their medications; 40% reported having stopped their medications on their own because of side effects, and 20% because of lack of efficacy. Mean CQR score was 69.1 +/- 10.5, suggesting moderate adherence overall. Differences were also observed across ethnic groups: 23% of ethnic minority patients had problems taking their medications at specified times compared to 11% of Whites (p = 0.03). Lower education and side effects were associated with lower adherence. No differences were observed between RA and SLE patients. Many patients with RA and SLE report problems with treatment adherence. These appear to be more prevalent in African Americans and Hispanics than Whites; the impact of decreased adherence on outcomes could be significant and should be considered when treating patients with RA and SLE.

Trust in physicians and elements of the medical interaction in patients with rheumatoid arthritis and systemic lupus erythematosus.

OBJECTIVE: To identify components of the patient-doctor relationship associated with trust in physicians. METHODS: We assessed 102 patients with systemic lupus erythematosus (SLE) or rheumatoid arthritis (RA) seen at publicly funded hospitals in Houston, Texas. Patients completed a self-response survey examining patient perceptions of the medical encounter and trust in their physicians. Evaluated components of physicians' behaviors included: informativeness, sensitivity to concerns, reassurance and support, patient-centeredness, and participatory decision-making style. Scales were scored 0 to 10, with higher numbers indicating more positive perceptions of communication. RESULTS: Seventy patients had RA and 32 SLE; 25% were white, 43% Latino, 31% African American, and 75% were female. Mean scores for the medical interaction and trust scales ranged from 6.2-7.1, indicating moderate degrees of positive perceptions. All components were highly and positively correlated with each other, and with trust, suggesting that these traits are all elements of a positive style of doctor-patient communication. In multivariate analysis, ethnicity, physicians' informativeness, physicians' sensitivity to concerns, patient-centeredness, disease activity, and patient trust in the US health care system were independent predictors of trust in physicians. A separate model examined the predictors of patient disclosure of information. Patient perceptions of physicians' patient-centeredness and severity of disease activity were independently predictive of patient disclosure of information. CONCLUSION: In patients with SLE and RA, trust in physicians is significantly associated with patients' ethnicity and their perceptions about specific components of physicians' communication style. Trust in physicians can be improved by using a patient-centered approach, being sensitive to patient concerns, and providing adequate clinical information. Furthermore, patients appear to be more willing to disclose concerns when physicians use a patient-centered communication style.

Determinants of treatment adherence in ethnically diverse, economically disadvantaged patients with rheumatic disease.

OBJECTIVE: To explore the determinants of adherence to medical recommendations, including drug therapy and appointment-keeping, among ethnically diverse and economically disadvantaged patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE). METHODS: Patients with RA and SLE were identified through chart review and were invited to participate in focus groups to examine their attitudes and beliefs regarding adherence to treatment and medical appointments. Eight focus groups (4 RA, 4 SLE) were conducted, with a total of 40 participants (22 SLE patients and 18 RA patients). Transcripts were analyzed using grounded theory techniques and qualitative analysis software to facilitate coding interpretation. RESULTS: The majority of participants reported experiencing difficulty in adhering to their treatment at least occasionally. Both SLE and RA patients reported similar barriers to treatment adherence: fear of side effects, financial problems, difficulty in navigating the public health system, and perceived treatment inefficacy. RA and SLE patients also revealed barriers to appointment keeping, including difficulties in scheduling, financial costs, transportation, and functional impairment limiting their ability to attend the clinic. CONCLUSION: Patients' perceptions of and experiences with the health system, physicians, medication effectiveness, and side effects influence their adherence to treatment and other medical recommendations. Strategies to improve adherence could include the following: attempting to modify patients' beliefs and perceptions regarding medication effectiveness, promoting realistic expectations about risk/benefit ratios, and improving access to health care by reducing barriers that limit the interaction between patients and the health system.
