Introduction Although messenger RNA (mRNA) vaccines have been developed and widely utilized to mitigate the coronavirus disease (COVID-19) pandemic, it is essential to describe the adverse events (AEs) following immunization. This study aimed to identify the patterns associated with serious AE reports after mRNA COVID-19 vaccination in the World Health Organization (WHO)’s global scale database (VigiBase). Methods This study performed a latent class analysis (LCA) of reports of serious AEs following mRNA COVID-19 vaccination from VigiBase between December 28, 2020 , and February 28, 2022 ( N = 312878). The Medical Dictionary for Regulatory Activities (MedDRA) System Organ Class (SOC) terms were selected for LCA. The reporting characteristics in accordance with the cluster were described. We used a multinomial logistic regression model to estimate the association between potential factors and each cluster. Results Five clusters of AE reports were distinguished through LCA: infection AEs (cluster 1), cardiac AEs (cluster 2), respiratory/thrombotic AEs (cluster 3), systemic AEs (cluster 4), and nervous system AEs (cluster 5). Compared to cluster 4, cluster 2 had a higher proportion of males (OR 2.98; 95% confidence interval (CI) 2.87–3.09), and cluster 1 had a longer time to onset than other AEs (≥ 14 days) (OR 16.2; 95% CI 15.5–16.9). Conclusion Using LCA, we found five clusters of serious AEs following mRNA COVID-19 vaccination. Each cluster was distinguished by potential factors such as age, gender, region, and time to onset. We suggest that monitoring should carefully consider the patterns of young males with cardiac AEs and elderly individuals with thrombosis after respiratory AEs. Our findings could contribute to enhancing understanding of safety profiles and establishing management strategies for serious AEs of special interest following mRNA COVID-19 vaccination.

Objectives This systematic aimed to understand the global status using the results of survey studies based on the Community Pharmacy Survey on Patient Safety Culture and set the directions of development in terms of the patient safety culture of community pharmacies. Methods Electronic searches were performed in EMBASE, MEDLINE, PubMed, and CINAHL databases by using the words “patient safety,” “culture,” and “community pharmacy” with synonyms or associated words in the original English language research articles published between January 1, 2012, and March 2, 2023. This systematic review was conducted based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Results Eleven surveys from 10 countries were selected. Five studies were conducted on pharmacists, whereas 6 studies were carried out on all pharmacy staff members such as pharmacists, technicians, clerks, and pharmacy students on apprenticeship. There was a considerable variation in the positive response rates across the dimensions of all the surveys. The highest positive response score was demonstrated for “teamwork” and “patient counseling,” whereas the “staffing, work pressure, and pace” dimension was essential for improving patient safety culture in community pharmacy settings. For overall rating of the pharmacy on patient safety, 84.8% of pharmacy staff members gave good, very good, or excellent as their responses. Conclusions Despite the differences among studies, findings of this study are expected to be used as valuable evidence to develop patient safety improvement strategies after reflecting each country’s health care setting or community pharmacy practice. Furthermore, the results would offer meaningful assistance to achieve the goals of global campaigns such as the World Health Organization Patient Safety Challenge.
This study identified trends in hydroxychloroquine (HCQ) prescription and retinopathy screening in patients with systemic lupus erythematosus (SLE) according to clinical practice guidelines to minimise the risk of HCQ retinopathy. We used data from patients diagnosed with SLE between 2004 and 2019 from the National Health Insurance Service in Korea. To assess trends of daily dose per actual body weight (ABW), we performed an interrupted time-series analysis and identified effects after revision of guidelines. Among 38,973 patients with SLE, 28,415 (72.9%) were prescribed HCQ from 2004 to 2019. The proportion of patients using HCQ among SLE patients was 63% in 2004 and increased to 76% in 2019. The median daily dose per ABW for HCQ users decreased from 5.88 mg/kg in 2004 to 3.98 mg/kg in 2019, and from 5.45 mg/kg in 2005 to 4.17 mg/kg in 2019 for HCQ new users. The annual implementation rate of screening tests among HCQ new users increased from 3.5% in 2006 to 22.5% in 2019. Study results indicated that HCQ dosing management was adequate based on the revised guidelines. Although the implementation rate of retinal screening has increased, it is necessary to enhance awareness of retinal screening in clinical settings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
