AB0338 BELIEFS ABOUT BIOLOGIC DRUGS AMONG RHEUMATOID ARTHRITIS PATIENTS

Rheumatoid arthritis (RA) is a chronic inflammatory disease requiring a long-term follow-up and the use of chronic therapies. The management of this disease is based on a multidisciplinary care, requiring total patient involvement. Previous personal experiences, the experiences of others and the daily impact of the disease on patients fuel their perceptions of the treatment especially biologic one. There are few studies evaluating patient’s beliefs about these drugs [1,2].The aim of our study was to investigate beliefs about biologic Disease-Modifying Anti-Rheumatic Drugs (bDMARDs) among patients with RA and to identify factors related to specific beliefs.We conducted a bi-centric cross-sectional study, including patients with RA fulfilling the ACR/EULAR 2010 criteria. All patients were on bDMARDs associated or no to conventional synthetic (sc) DMARDs. Sociodemographic, clinical, biologic, and therapeutic data were collected. Patients were interviewed about their medication beliefs using the Beliefs about Medicines Questionnaire (BMQ).There were 75 RA patients: 60 female (80%) and 15 males (20%). The sex ratio was about 0.25. The mean age was 56.92 ± 9.06 years [34-80]. Thirty-three percent of patients were illiterate. Twenty patients were employed. Sixty-four patients (85.3%) were married. The mean disease duration was 14.85 ± 8.5 years [2-39]. Thirty-three patients had joint deformities. Twenty-seven patients had extra-articular manifestations and thirty-six patients had comorbidities. The mean disease activity scale (DAS28 CRP) was 3.94 ± 1.32 [1.21-7.15]. Fifteen patients (20%) had high disease activity, 11% had low disease activity, and 19% were in remission. The mean functional impairment scale (HAQ) was 0.64 ± 0.48 [0-2.2]. Twelve patients had moderate to severe disability and only one patient had severe to very severe disability. The mean duration of the current bDMARD was 37.17 ± 39.44 months and the mean rank of the current biotherapy was 1.41 ± 0.9 [1-5].Regarding the BMQ, the mean score for General Overuse was 14 ± 2.37 [6-20]. The mean score for General Harm was 10.82 ± 4.42 [4-20].The mean score of patients’ specific beliefs regarding the necessity of taking the current bDMARD (Specific Necessity) was 20.62 ± 5.71 [5-25]. The mean Specific Concerns score regarding the current bDMARD was 10.33 ± 3.29 [5-25]. Necessity about taking bDMARD was reported by 77.3% patients in the present and 61.3 % patients consider maintaining the bDMARD in the future.There were 4% of patients who reported concerns about taking bDMARD. Twenty four percent of patients reported concerns about long term effects, and 16% about becoming too dependent on bDMARD.Beliefs about the necessity to stop occasionally chronic therapies were reported by 13.3% of patients.Specific necessity was correlated to the current bDMARD duration (p=0.01), Patient Global Evaluation (p=0.03), VAS pain scale (p<10-3), the number of nocturnal awakenings (p=0.01), tender joint count (p<10-3), swollen joint count ((p<10-3), HAQ (p=0.005), DAS28 (CRP) (p<10-3). Specific concerns were correlated to the actual bDMARD rank (p=0.01).Our study showed stronger beliefs in the necessity of taking biologic drugs if indicated. Disease activity parameters and functional impairment influence those beliefs. Further studies are required to evaluate the impact of beliefs on biologic drug adherence.[1]Cea-Calvo L, Raya E, Marras C, Salman-Monte TC, Ortiz A, Salvador G, et al.
