Effectiveness of an intervention to increase the knowledge, attitude, and practice regarding the return and disposal of unused medications

Assessment of general population knowledge, attitude, and practice on safe unused and expired drugs disposal: a cross-sectional study

Background

The appropriate disposal of medication is a well-recognized issue that has convened growing recognition in several contexts. Insufficient awareness relating to appropriate methods for the disposal of unneeded medicine may result in notable consequences. The current research was conducted among the public in Iraq with the aim of examining their knowledge, attitude, and practices regarding the proper disposal of unused and expired medicines.

Methods

The present study used an observational cross-sectional design that was community-based. The data were obtained from using an online questionnaire. The study sample included people of diverse genders, regardless of their race or occupational status. The study mandated that all participants meet two criteria: firstly, they had to be a minimum of 18 years old, and secondly, they needed to have permanent residency status in Iraq.

Results

The research population consisted of 591 participants from general population. The majority of participants were men (64.8%) with average age of 33.5±9.1 years. The majority of participants (˃50%) answered four out of eight knowledge questions correctly. There were significant (P-value ˂0.05) differences in four knowledge items about disposing of unused/expired medications according to the educational level. Elder participants had significantly higher knowledge about the disposing of unused/expired medications compared to younger ones. More than 84% correctly agreed that improper disposal of unused and expired medication has adverse effects on environment. Although the majority of the participants had positive attitude toward the safe disposal of unused/expired medications, their actual practice was improper for these medications. Approximately 70% of the participants have disposed unused/expired medications into their home trash can.

Conclusion

Despite increasing awareness from the general populace about the possible harm and substantial hazards linked to expired medicines, there is an absence of understanding concerning the proper techniques for disposing of and managing these prescriptions.

Assessment of knowledge, attitude, and practice regarding the disposal of expired and unused medications among the Lebanese population

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.
