This is the first SLR to investigate residual symptoms and disease burdens in RA patients in remission or LDA. The results indicate that despite achieving conventional clinical targets, the disease continues to affect patients, suggesting the existence of unmet need under the current treatment paradigm.

The COVID-19 pandemic caused a major upheaval to the lives of people and placed a strain on societal mental health. The aim of this research is to estimate the impact of the pandemic on the mental condition of the Polish population measured through the consumption of relevant medication and medical leave of absence from the workplace. Methods: We analyzed national-level data on the consumption of pharmaceuticals used in clinical practice in Poland in the treatment of depression and anxiety alongside medical absence in the workplace using the Interrupted Time Series model to estimate the significance of the pandemic. Results: We found no significant change regarding the consumption of pharmaceuticals with the development of the pandemic. Conversely, medical leaves of absence for psychiatric reasons increased significantly with the onset of COVID-19. The influence was strongest in the diagnosis of anxiety or reaction to severe stress and weakest in recurrent depression. Conclusion: The pandemic had a significant influence on the ability to work for psychiatric patients in Poland but did not change pharmaceutical use. Physicians should consider the mental health of patients impacted by the anti-epidemic measures. Further study is needed to fully understand the long-term impact of the pandemic on mental health in Poland.

High medication costs are one of the major barriers to patient adherence. Medication affordability might be improved by generic substitution. The aim of this study was to assess the effectiveness of the implementation of generic substitution mechanisms in Poland. This was a retrospective analysis of nationwide real-world big data corresponding to dispensation of metformin preparations in 2019 in Poland. Relevant prescription and dispensation data were compared to assess the prevalence of generic substitution and its economic consequences. Among the 1,135,863 e-prescriptions analysed, a generic substitution was found in only 4.81% of the packs dispensed, based on e-prescriptions issued for metformin under its originator version and 2.73% under generic drugs. It is estimated that if these values were applied to the total Polish drug market, patients could lose the opportunity to lower their co-payment by 15.91% and the national payer to reduce its reimbursement expenditures by 8.31%. Our results point at the suboptimal implementation of generic substitution in Poland. Therefore, relevant actions need to be taken in order to maximise the benefits provided by this mechanism. It could not only lead to the win-win scenario in which both patients and the national payer are secured substantial savings, but it could also have a positive impact on patient adherence.
