Pharmacy students' knowledge and practices concerning the storing and disposal of household medication in Saudi Arabia

A systematic review of the knowledge, attitude and practice of healthcare professionals and healthcare professional students towards household pharmaceutical waste disposal

Background

Active pharmaceutical residues introduced into the environment through irresponsible household disposal of unused and expired medication can damage nature and health. Through medication take-back programmes, these risks can be mitigated. However, healthcare professionals' neglect of their responsibility to ensure proper disposal practices has perpetuated subpar norms among the public.

Objectives

The objectives of this systematic review were to assess the knowledge, attitude, and practice of household pharmaceutical waste disposal among healthcare professionals and healthcare professional students as well as to compare their respective levels of knowledge, attitude and practice.

Methods

A systematic search of published articles from 2014 to 2023 in three online journal databases (Pubmed, Scopus, and Web of Science) yielded an initial pool of 10,381 records, which was narrowed down by title and abstract screening to 46 relevant publications for full-text examination and the final inclusion of 21 papers for data extraction and synthesis.

Results

The findings revealed deficiencies in academic curricula and medication disposal training, leading to inadequate knowledge and perceptions among healthcare professionals. Many healthcare professionals consider public education about safe medication disposal practices to be outside their job descriptions, leading to infrequent communication of medication disposal methods to their consumers and service users. Additionally, inadequate and inaccessible infrastructure further hinders proper medication disposal practices despite awareness of the consequences.

Conclusions

This study provides insights for policymakers and educators to address these and enhance healthcare professionals' participation in improving safe medication disposal practices. Efforts to strengthen training programmes, incorporate comprehensive education on medication disposal into curricula, and improve infrastructure for safe medication disposal are essential to effectively address the issue of household pharmaceutical waste disposal.

UAE pharmacists' perceptions of the causes of unwanted or unused medications, their practices, and barriers to promoting safe medication disposal by the public

BACKGROUND

The improper disposal of unwanted or unused medications is a pressing issue that can lead to drug misuse and environmental contamination. Pharmacists play a crucial role in promoting safe drug disposal by the public. This study explores pharmacists' perceptions of the causes of unwanted and unused medications, their practices, and the barriers to promoting safe medication disposal among the public in the United Arab Emirates.

METHODS

This cross-sectional study included pharmacists working in the UAE's community and hospital settings with direct patient contact. A convenience sampling approach was used, where pharmacists who were available during the data collection period were invited to participate. Printed copies or a survey link to the questionnaire were provided to pharmacists to complete independently during in-person visits. Participants were categorised into three levels: extensive, adequate, or minimal involvement, based on their engagement in activities such as reviewing patients' medications, educating them on proper storage and disposal, and participating in drug take-back programmes. Chi-square test was used to assesses the association between categorical variables and pharmacists practice levels. The data was analysed using the Statistical Package for the Social Sciences (SPSS) software version 29.

RESULTS

A total of 370 pharmacists participated in this survey, most of whom were between 18 and 34 years old (69.2%). The top three perceived causes of unwanted or unused medications include changes in prescriptions due to patients' poor clinical outcomes (83.8%), inappropriate storage conditions (79.7%), and expiration of medications (78.6%). Moreover, factors such as pharmacist age, type of pharmacy, country of education, pharmacy location, employment status, and years of experience were significantly associated with pharmacists' level of involvement in promoting safe medication disposal practices. The most cited barriers were a lack of public awareness about the risks of improper medication disposal (88.9%), lack of time due to workload (82.4%), and lack of training and education (78.1%). Most pharmacists believed in collaborating with public health agencies to promote medication disposal awareness (97.6%) and developing national guidelines (97.6%).

CONCLUSION

This study's findings have significant implications for public health, highlighting the necessity of essential groundwork for developing targeted interventions and policies to enhance public awareness and identify specific areas where pharmacists can actively encourage safe medication disposal practices in the UAE.

Storage practice and wastage of pharmaceuticals in Chinese urban-dwelling households: Description of urban-dwelling households

At-home storage of medications could pose a threat to public health and the environment if not handled appropriately. Excessive storage also creates health care and economic burdens. This study investigated storage practices, waste, and their determinants in China. Data were collected by pharmacy staff of urban-dwelling households via online questionnaires. Descriptions at the household and medicine levels were conducted in Stata 16. Individual and family characteristics were associated with the presence of household medicine storage (84.6%, n = 5290), but storage location was poor. Expiration was the primary reason for discarding medicines. Respondents were inclined to buy medicines in pharmacies without prescription for storage purposes at out-of-pocket expenses, and 60.7% of medicines were purchased at out-of-pocket expenses, despite medical insurance coverage. Regarding wastage, 11.2% of medicines had expired and 38.2% were no longer needed. Purchasing for storage purposes was related to less waste due to expiration, while purchasing for treating acute diseases rather than chronic diseases was related to more waste, due to less for use. Accounting for 12.2% of all medications, antibiotics were associated with expiration and no further need for use. Source-control measures targeting health facilities, pharmacies, and residents are needed under the combined efforts of all relevant departments.

Future Healthcare Workers and Ecopharmacovigilance: Where Do We Stand?

With the rapid development of the pharmaceutical industry and constant growth of drug usage, ecopharmacovigilance (EPV) has emerged as a way of coping with and minimizing the effects that drugs have on the environment. EPV concerns and describes unwanted effects that the use of a specific drug could have on the environment. The US, EU and Cananda are the improving position of EPV, both in legislation and practice. EPV requires further development as previous studies have shown that neither the general population nor healthcare professionals have enough knowledge about the subject. Improving awareness and knowledge about this topic is a key task for the future of EPV. The main objective was to determine students' level of knowledge about ecopharmacovigilance and to examine ways of storing and disposing of unused and expired drugs. Students' knowledge and habits were examined by a previously published survey. The survey contains twenty questions divided into three parts and the possibility of writing an additional note. There was no difference in the level of knowledge between the students of different studies. Also, students who had a family member working as healthcare professional did not show a higher level of knowledge compared to the others. Pharmacy students had a greater intention to educate their environment about EPV when compared to students of the other studies. This is in the line with a previous study which showed that the general public expects that pharmacists and physicians educate them about EPV. Medicine and dental medicine students will become prescribers after finishing their studies, and as such, they should be informed about eco-directed sustainable prescribing (EDSP) as part of an EPV strategy. More than half of the participants reported good adherence to prescribers' instruction, which decreased the amount of unused drugs. Most of the students found that the drug expiration date was legible, but they did not check it often. In comparison with similar studies, Croatian students had more knowledge and better practices concerning EPV and drug disposal. Structured learning strategies and curriculum implementation for EPV are much needed for further raising awareness about the subject among healthcare professionals and the public.

Unused, expired pharmaceuticals and their disposal practices among the general public in Burdur-Türkiye: a cross-sectional study

BACKGROUND

Unused pharmaceuticals are currently a public health problem. This study aimed to identify unused pharmaceuticals, research practices about the disposal methods, classify the medicines according to Anatomical Therapeutic Chemical codes (ATC) and, to determine the number of unused medicines.

METHODS

The study was designed as a cross-sectional study. Data were collected between April and August 2023 in Burdur-Türkiye by non-probability sampling technique (convenience method). Pharmaceuticals were classified according to ATC. Statistical Package for Social Science SPSS (V.24) package program was used for data analysis.

RESULTS

A total of 1120 people, 1005 in the first sample group and 115 in the second sample group, participated in the study. Findings of first sample group: A total of 4097 boxes of unused pharmaceuticals (4.7 ± 4.3 boxes/per capita) were detected. It was found that pharmaceuticals were stored in areas such as kitchens (59.1%) and refrigerators (38.6%), the reason for keeping them was reuse (41%), and the disposal practice was household garbage (81%). Paracetamol (648 boxes), Other cold preparation (303 boxes), Dexketoprofen (239 boxes), Diclofenac (218 boxes), Amoxicillin and beta-lactamase inhibitor (190 boxes) were found to be the most frequently unused pharmaceuticals. Using the unused medicines at home without consulting a physician was 94.1% (self-medication). Findings of second sample group: Of the 6189 dosage forms in 265 boxes pharmaceutical, 3132(50.6%) dosage forms were used and 3057(49.4%) were found to be unused.

CONCLUSION

There is a significant amount and number of unused medicines in households, and self-medication is common. Medicines are not properly disposed of and some of them expire. Public information is needed. A "drug take-back system" for unused medicines can be useful in solving this problem.

Drug take-back program: assessment of knowledge, practices, and barriers to safe disposal of unused medication among healthcare students in a Nigerian university

BACKGROUND

The safe disposal of unused medication is a critical public health issue, with risks including environmental pollution, accidental ingestion, and misuse. Inadequate adherence to proper disposal methods among healthcare students could affect the practice of safe disposal of unused medicines as future healthcare professionals. This study, conducted at a Nigerian university, aimed to assess the knowledge, adherence to safe disposal practices, and barriers faced by healthcare professional students regarding unused medication disposal.

METHODS

A cross-sectional study was carried out among 930 healthcare students in a Nigerian University, comprising medical and surgery, nursing, pharmacy, physiotherapy, and medical laboratory science students. Information was gathered from respondents using a self-administered questionnaire. Multivariate analyses were used to evaluate the relationship between specific variables and participants' knowledge and practice scores, while chi-square and logistic regression tests were used for categorical variables at p < 0.05.

RESULTS

A total of 930 students participated in this study. The results revealed a significant gap in knowledge, with (67.7%; 630) of the participants unaware of proper disposal methods and most scoring either 0 (31.9%; 297) or 1 (46.0%; 428) out of 4 on a knowledge-based questionnaire. Pharmacy students were the most knowledgeable, with 44.4% falling into the high knowledge category. However, their knowledge did not always correspond to correct practices, with only (10.1%; 94) of participants reporting use of recommended disposal methods such as returning unused medicine to a pharmacy or a drug take-back program. Significant associations were found with course of study (χ²=12.14, p = 0.033) and awareness of correct disposal methods (χ²=4.035, p = 0.045). Those aware of the correct disposal method had a higher odds ratio of high knowledge score (OR = 1.62, 95% CI: 1.1-2.41, p = 0.018) compared to those who were not aware. In terms of disposal practices, those who had received training on safe disposal had significantly higher odds of good practice score (OR = 2.25, 95% CI: 1.36-3.74, p = 0.002). Major barriers identified included lack of access to drug take-back programs (50.4%; 469), lack of knowledge (36.8%; 342), and inconvenience (10.3%; 14).

CONCLUSION

A knowledge gap was revealed among the respondents regarding the safe disposal of unused medications. Despite the presence of knowledge and awareness, these do not necessarily translate into good disposal practices. This call for strategies to overcome identified barriers, with the aim to bridge the knowledge-practice gap and promote safe disposal of unused medication. The study underscores the urgent need for improved public health policies and educational programs on safe medication disposal.

Ecopharmacology: Knowledge, Attitude, and Medication Disposal Practice Among Pharmacy Students

Background

Ecopharmacology, as a form of drug management for the environment, focuses on the impact of drugs on the environment. Pharmacists, and by extension pharmacy students, are expected to play an important role in ecopharmacology. Therefore, this study was conducted to determine the knowledge and attitude towards ecopharmacology and the practice of disposal of leftover or expired medicines among pharmacy students.

Methods

This was a descriptive cross-sectional study among pharmacy students in Northwestern Ethiopia. The study took place from May 1 to June 15, 2023. A self-administered questionnaire was used for data collection.

Results

Four hundred and forty-five students were included in the study. Only 91 (20%) of the students were aware of the term ecopharmacology, 27% knew that excretion from the human or animal body is the major route by which pharmaceutical agents enter the environment, and 42% were aware of the risk of increased antimicrobial resistance due to antibiotic residues in the environment. In addition, only 27% of respondents reported receiving information about the disposal of pharmaceuticals. The most common method of disposing of medications was throwing them away in household trash (61.8%).

Conclusion

Our results suggest that while most pharmacy students in Ethiopia have a positive attitude toward ecopharmacology, they do not know enough about ecopharmacology and dispose of their medicines poorly. More uniform education in ecopharmacology and pharmaceutical pollution might be warranted in the pharmacy curriculum.

Safe Disposal of Unused Medicine among Health Professions Students at Makerere University: Knowledge, Practices and Barrier

Background

Environmental contamination with antimicrobial agents is one of the leading drivers of antimicrobial resistance (AMR) worldwide. However, scarce data exists concerning the factors fueling unsafe disposal of medicines globally. This study aimed to assess for the knowledge, practices, and barriers concerning safe disposal of unwanted medicines among health professions students (HPS) at Makerere University, Uganda.

Methods

We conducted a cross-sectional study using an online assessment tool sent through WhatsApp groups and E-mail addresses of undergraduate HPS at the College of Health Sciences Makerere University, Uganda between 1stFebruary and 16thMarch 2022.Good knowledge was defined as a score of 80% of the knowledge domain questions on a standardized questionnaire.

Results

We enrolled 205 participants, 135 (65.9%) were male, with a median age of 23 (range: 19 -43) years. Overall, 157 (76%) participants had good Knowledge. The mean knowledge score was 63%. About half (n=102, 49.8%) of the participants had unused medicines kept at their respective residential places, mainly antibiotics (27%, ×/102) and analgesics (21 %, ×/102). The most common method of medicine disposal was dumping into household garbage (n=103, 50.2%). Only 37 (18%) of participants had ever used the take-back method of medicine disposal. The most reported barriers for safe disposal were inadequate knowledge and insufficient advice from the dispensers concerning safe disposal practices. Year of study was the only factor significantly associated with knowledge about safe disposal of medicines, (adjusted Odds Ratio: 9.7, 95%CI 2.3 - 40.5, p= 0.002), with participants in higher academic years having more knowledge than those in lower years.

Conclusion

Despite a good knowledge level among the participants, the practice of safe disposal of unused medicines remains suboptimal in this population. Strategies aimed at enhancing safe disposal practices such as giving proper instructions to medicine buyers by dispensers regarding disposal practices are recommended to abate the growing burden of AMR.

Household Pharmaceutical Waste Disposal as a Global Problem-A Review

The negative effect of the pharmaceuticals presence (persistence?) in various components of the environment is a global problem today. These compounds are released into the environment as a result of, inter alia, their use and improper disposal. Therefore, it is important to reduce excessive drug consumption and to develop a system for the collection of unused/expired pharmaceuticals. The effectiveness of actions in this area is inextricably linked with the need to educate society on how to deal properly with unwanted medications. The aim of the study was to show that the inappropriate handling of unused/expired drugs by society is an important problem in waste management systems, and it impacts the state of the environment. Forty-eight scientific articles published between 2012 and 2021 were taken into account that discussed the systems in various countries for the collection of unused/expired pharmaceuticals. This literature review shows that the main method of disposing of unused/expired medications, according to respondents from different countries, is either by disposing of them in household waste or flushing them into the sewage system. This is also the case in countries with systems or programs for the return of redundant drugs, which indicates that these systems are not sufficiently effective. This may be influenced by many factors, including the lack or ineffective education of the society.

Pharmacy and Nursing Students' Knowledge and Practices Concerning the Disposal of Unused and Expired Medicines in Kosovo

This descriptive cross-sectional study aimed to assess the knowledge and practices of pharmacy and nursing students at a medical college in Kosovo concerning unused and expired medications. A self-administered questionnaire was distributed to 500 randomly selected students of pharmacy (200 questionnaires) and nursing students (300 questionnaires). Overall, 336 returned the filled forms and the response rate was 67.2. SPSS version 26.0 was utilized for statistical analysis. The results showed that 89.2% of pharmacy students and 82.2% of nursing students check the expiration date of medications before purchasing them and a considerable number of students stated that they possess unused medicines at home (78.4% of pharmacy and 74% of nursing students). Regarding disposal practice, over 50% of both nursing and pharmacy students dispose of unused and expired medications in the trash. A small proportion of students returned unused or expired medicines to the pharmacy (11.4% of pharmacy students and 10.7% of nursing students return unused medications, whereas 14.4% of pharmacy respondents and 10.1% of nursing respondents reported returning expired medicines). There was a statistically significant difference in the ways pharmacy and nursing students purchase pharmaceuticals and in their opinions regarding institutions in charge of disposing of unused and expired medicines (p = 0.000). Students are aware of the detrimental effects improper disposal of unused and expired medicines has on the environment and public health, but lack information regarding the return of unused and expired medicines to the pharmacy. To change the existing practice the most appropriate method would be to add additional lectures on safe disposal practices into existing modules. It is recommended for involved stakeholders in Kosovo to organize training, seminars, and workshops for health professionals especially pharmacists and nurses, since they pass the information to patients/consumers as well as the government to make amendments to current legislation to ameliorate the returning procedures for patients/consumers in pharmacies.
