The aim of the work. Comparative analysis of the pharmacotherapy of patients with rheumatoid arthritis (RA) in a health care institution and estimation of the impact of existing treatment protocol on the drugs prescribing.
Materials and Methods. The object of the study were medical cards and medical records of 89 and 108 inpatients with RA, who were treated in the Rheumatology Department of the City Clinical Hospital of Lviv No. 4 in 2009 and 2019 correspondingly. Methods of data retrieval, frequency, comparative, content analysis, data aggregation and cluster analysis were used.
Results and Discussion. Content analysis of medical records revealed that three groups of drugs were used for the pharmacotherapy of RA. They were disease-modifying antirheumatic drugs (DMARDs), glucocorticosteroids (GCS) and nonsteroidal anti-inflammatory drugs (NSAIDs). During the analysed period, the share of DMARDs prescribing significantly increased and the share of NSAIDs indications decreased. Comparative analysis of the schemes of pharmacotherapy of patients with RA allowed establishing an increase in the share of prescribing of those treatment schemes that use DMARDs, which meets the requirements of the current clinical protocol of medical care for patients with RA. Based on the cluster analysis of 24 international non-proprietary names of drugs, three groups of them were identified according to the frequency of their prescribing. To the first group belonged drugs that were not prescribed in 2019. The second and third groups included drugs – leaders and drugs with medium and low level of prescribing correspondingly.
Conclusions. The analysis of prescribed DMARDs, GCS and NSAIDs for RA pharmacotherapy showed a significant influence of clinical protocols on the choice of RA treatment tactics. Cluster analysis allowed dividing drugs into groups and identifying the most perspective drugs for the RA treatment.
