Background Medication waste is a public health problem affecting developed and developing countries. In Lebanon, a developing country in the Middle East, efforts are being deployed in hospitals but not in the community. Objective This study aimed to validate a questionnaire to explore the knowledge, attitude, and practice (KAP) towards the disposal of unused and expired medicines among the Lebanese population and then identify the factors associated with these variables comparatively between the general population and healthcare professionals. Methods A cross-sectional study was conducted among the general Lebanese population in May–June 2022 using a standardized questionnaire. The validity and reliability of the KAP scales were assessed, then a thorough statistical analysis was done to explore the factors associated with these scales. Results The KAP scales generated by this study were valid and reliable. Using these scales, 24.5%, 22.6%, and 21% of participants demonstrated proper knowledge, attitude, and practice, respectively. Higher knowledge scores were significantly associated with female gender (Beta = 0.97), a high monthly income (Beta = 1.68), a secondary (Beta = 6.11) or university (Beta = 6.80) education level, and postgraduate education (Beta = 7.13). However, older age (Beta = − 0.06) and a low monthly income (Beta = − 3.06) were significantly associated with lower knowledge scores. A higher knowledge score (Beta = 0.06) was significantly associated with a more positive attitude regarding unused or expired medication disposal. Being a healthcare professional (Beta = 0.72) was significantly associated with a higher practice score, while being a female (Beta = − 0.32) and living in a rural area (Beta = − 0.37) were significantly associated with lower practice scores. Conclusion This study validated KAP scales regarding medication waste in Lebanon and showed low KAP scores in the majority of respondents. Factors associated with higher KAP scores in various aspects of medication disposal, including gender, age, education level, and profession (healthcare professionals), suggest the need to consider those when implementing targeted corrective measures. Although further studies are required to confirm our findings, this study could be the ground for a medication waste management national strategy in Lebanon.

Background:Increases in mental health problems have been observed during COVID-19 pandemic. Therefore, this topic of research became a priority, especially at the academic level. The objectives of this review were to summarize an institutional contribution to mental health research during the era of COVID-19. Methods: A scoping review of studies conducted at a local university and examining alterations in mental health during the pandemic during the last three years was conducted. Results: Fifty-five studies were included. These focused on different mental health changes that occurred in the era of COVID-19 such as changes in work habits or existing psychological conditions, COVID-19-related fear depression, anxiety and stress. Most of the included studies were observational (76.7%). The majority of the publications were published in Scimago Journal Rank Q1 journals (57.1%). The average number of citations per publication was 15.3±30.13 [0-125]. The number of citations was higher in papers with international collaboration of authors (p=0.031). Publications with COVID-19 as a main objective were more cited than papers not directly related to this subject (25.9±39.45 vs. 4.14±3.2; p=0.044). Conclusion: Mental health problems are a common response to the COVID-19 pandemic. The contribution of a local university to different mental health research studies that took place during COVID-19 outbreak have underlined this reality. However, more representative research from other institutional settings will be needed, particularly in vulnerable populations.
