Evaluation of Therapeutic Adherence in Patients Suffering from Chronic Inflammatory Rheumatism in the Rheumatology Wards of Lomé (Togo)

Objectives: Therapeutic compliance can be defined as the degree of adequacy between a patient’s behaviour and his doctor’s recommendations. Non-adherence to treatment has serious consequences in terms of morbidity and mortality. Our aim was to assess adherence among patients treated for chronic inflammatory rheumatism in Lomé. Patients and Methods: This was a multicentre cross-sectional study conducted from January 2015 to December 2021. Patients aged 18 years or older, treated in the rheumatology departments of the Sylvanus Olympio University Hospital or the Bè Hospital during the study period, were included if they were diagnosed with chronic inflammatory rheumatism and started on disease-modifying therapy. Adherence was assessed using the Compliance Questionnaire Rheumatology 19 questionnaire, with a threshold for good compliance set at 80%. Results: Out of 13,214 patients received, 159 suffered from chronic inflammatory rheumatism (hospital frequency 1.5%), and 60 met the inclusion criteria for our study. There were 55 women (91.7%) and 5 men (8.3%), giving a sex-ratio of 1/11. The mean age was 49.5 ± 13.5 years (extremes: 19 and 78 years). Rheumatoid arthritis (68.3%) was the most common rheumatic disease, followed by undefined rheumatic diseases (16.6%) and spondyloarthritis (8.3%). Average compliance with treatment was 76.9% ± 12.4% (extremes 29.8 and 91.2). There was no statistically significant difference according to the type of rheumatism. Conclusion: Overall compliance was poor, with a Compliance Questionnaire Rheumatology 19 of less than 80%. It was non-significantly influenced by socioeconomic status, disease severity and duration of progression.
