Kepatuhan pasien Lupus Eritematosus Sistemik (LES) berperan penting dalam mencapai aktivitas penyakit yang terkontrol. Penelitian ini bertujuan untuk mengetahui prevalensi ketidakpatuhan, faktor-faktor yang berhubungan dengan ketidakpatuhan, dan hambatan minum obat pada pasien LES. Data potong lintang diperoleh dari pasien Poliklinik Alergi-Imunologi RSUPN Dr. Cipto Mangunkusumo secara konsekutif pada Juli–Agustus 2023. Dilakukan evaluasi terhadap ketidakpatuhan pengobatan (self-report medication-taking behaviour measure for thai patients scale; MTB-Thai), komorbiditas, jumlah obat, aktivitas penyakit (skor MEX-SLEDAI), depresi (Hospital Anxiety and Depression Scale; HADS), dan hambatan lain dalam pengobatan (Identification of Medication Adherence Barriers Questionnaire; IMAB-Q 30). Data kategorik dianalisis dengan uji Chi-square atau Fisher, sedangkan data numerik dianalisis dengan uji Mann-Whitney. Dari 100 pasien LES dewasa, mayoritas merupakan perempuan (97%), dewasa muda (61%), menamatkan pendidikan tinggi (48%), dan memiliki aktivitas penyakit remisi˗ringan (90%). Median (IQR) jumlah obat yang dikonsumsi 6 (5–8). Prevalensi ketidakpatuhan minum obat mencapai 27%. Tingkat pendidikan pasien ditemukan berhubungan dengan ketidakpatuhan (pendidikan menengah vs. pendidikan tinggi, 59,3% vs. 40,7%; p=0,035). Pasien yang tidak patuh memiliki skor hambatan minum obat yang lebih tinggi secara signifikan (p<0,001). Hambatan yang paling banyak dialami pasien yang tidak patuh adalah kekhawatiran terhadap efek samping dan mudah terdistraksi dari mengonsumsi obat-obatan.

Medication adherence among patients with systemic lupus erythematosus (SLE) is essential to achieve controlled disease activity. This study aimed to investigate the prevalence of non-adherence, associated factors, and medication adherence barriers among patients with SLE. Cross-sectional data were obtained from consecutive patients at Allergy-Immunology Clinic Cipto Mangunkusumo Hospital between July–August 2023. Evaluation was conducted on medication non-adherence (self-report medication-taking behavior measure for thai patients scale), comorbidities, number of medications, disease activity (MEX-SLEDAI score), depression (Hospital Anxiety and Depression Scale), and other adherence barriers (Identification of Medication Adherence Barriers Questionnaire-30). Categorical data were analyzed with Chi-square or Fisher test, while numerical data were analyzed with Mann-Whitney test. Of 100 adult SLE patients, most were female (97%), young adult (61%), completed higher education (48%), and had remission˗mild disease activity (90%). The median (IQR) number of medications consumed was 6 (5–8). The prevalence of medication non-adherence was 27%. Patient's educational level was found to be associated with non-adherence (secondary education vs. higher education, 59.3% vs. 40.7%; p=0.035). Non-adherent patients had significantly higher medication adherence barrier scores (p<0.001). The most common barriers experienced by non-adherent patients were concerns about harmful side effects and easily distracted from taking medications.
