The Prevalence of Unused Medications in Homes

Pharmacist-led interventions in addressing improper disposal practices of unused and expired household medication: A systematic review

Background

Improper household medication disposal practices are a source of significant threat to environmental safety and public health. Pharmacists play a crucial role in mitigating these risks by educating the public about proper medication disposal. Evidence regarding the effectiveness of efforts conducted by health professionals to reduce the risks associated with improper disposal practices is still lacking. Therefore, this study aimed to systematically review pharmacist-led interventions in addressing unused and expired household medication disposal.

Method

A comprehensive literature search was conducted using PubMed, Scopus, and Google Scholar databases to identify studies evaluating pharmacist-led interventions and the effectiveness in improving household medication disposal practices until January 2024 with no constraints on publication year. Two reviewers independently performed the study selection process, data extraction, and outcomes assessment. Subsequently, the entire collected data were extracted and synthesized using qualitative and quantitative methods.

Results

The results showed that two among the total 83 studies retrieved during the search process met the inclusion criteria. The identified pharmacist-led interventions included the provision of an at-home medication disposal kit and an informational handout on proper disposal. However, these interventions showed no significant effects in improving household medication disposal practices, and all studies reported a low engagement rate with interventions.

Conclusion

The systematic review identified limited literature on pharmacist-led interventions for unused and expired household medication disposal practices, with no observed significant effects. Active patient and pharmacist engagement were required to enhance the effectiveness of interventions. Furthermore, the included limited studies suggested the need for the development of more pharmacist-led interventions to facilitate the role of pharmacist in educating the public on proper household medication disposal.

Unused medicine take-back programmes: a systematic review

Background

Improper disposal of unused medicine can impact the environment causing significant healthcare and financial burdens. While the medicine take-back programme is an effective management strategy, its effectiveness differs across countries. This study aimed to systematically review the take-back programmes in various countries and to identify areas needing improvement for programme enhancement.

Methods

We conducted searches in Medline, EMBASE, CINAHL, Web of Science, Scopus, and Google Scholar, from database inception to June 2023.

Results

The review included 27 studies spanning 15 countries' medicine take-back programmes. While some programmes, mostly observed in the USA, were conducted at the local level with non-health-associated facilities, others were done at the national level within healthcare facilities. The cost of collected medicines ranged from US$7,416 to US$1,118,020, primarily involving medicines related to the nervous system, cardiovascular system, alimentary tract, and metabolism. Legislations pertaining to these programmes were available in the USA, most European countries, and Mexico, but unavailable in Spain, Austria, Australia, and New Zealand. However, despite this, the government or the industry in these countries managed the programmes.

Conclusion

Well-structured take-back programmes featuring easily accessible collection points, regular collection schedules, clear programme ownership, with legislation defining financial responsibilities, showed positive outcomes.

Do pharmacists counsel customers on the disposal of unused or expired household medications? A national survey among 1,596 pharmacists in Indonesia

Introduction

Pharmacists play a vital role in counseling customers on proper medication disposal, yet their consistency in providing such information is often lacking. This study aimed to assess pharmacists' awareness of appropriate disposal practices for unused and expired household medications. Additional objectives included evaluating whether pharmacists offer disposal information during counseling, measuring their willingness to receive medication waste from the public, and identifying associated factors.

Methods

A national cross-sectional online survey employing convenience sampling was conducted among pharmacists working in hospitals, pharmacies, clinics, or community health centers (CHCs) in Indonesia, using a validated questionnaire to assess awareness, information provision, and willingness to receive medications for disposal. Binary logistic regression, with 95% confidence intervals (CI) and odds ratios (OR), explored potential associations between factors and outcomes.

Results

This study involved 1,596 pharmacists across 37 Indonesian provinces. Most pharmacists were women (80.4 %), aged 31-40 years (49.3 %), with a pharmacist professional background (93.8 %), working in CHCs (41.2 %), and practicing for 1-5 years (51.0 %). More than half were unaware of guidelines for returning medications to health facilities. While 69.9 % never counseled customers on disposal practices, 64.9 % expressed willingness to receive unused and expired medication from the public. Pharmacists practicing for at least six years were more likely to provide disposal information during counseling (OR: 2.54; 95 % CI: 1.44-4.47). Conversely, those in clinics (OR: 2.16; 95 % CI: 1.29-3.62), CHCs (OR: 2.07; 95 % CI: 1.45-2.95), or hospitals (OR: 2.00; 95 % CI: 1.27-3.14) were more likely to be unwilling to receive expired and unused household medication.

Conclusions

The study reveals that most pharmacists, particularly those with limited practice duration, lacked awareness regarding the importance of proper medication disposal and did not provide counseling on appropriate medication disposal to patients. To address this issue, there is a pressing need for intensified education intensified education at the undergraduate level, continuous training for pharmacists, and a clear policy and practical guidelines, particularly targeting pharmacists in clinics, CHCs, and hospitals, to facilitate the acceptance of unused and expired household medications.

Medication reuse programs: a narrative review of the literature

A proportion of returned medications may potentially meet quality standards to be reused safely. In Australia, there is no regulatory guidance available to facilitate such medication reuse. This narrative review aimed to identify and review international literature describing medication reuse programs to provide insight into their implementation and potential barriers. Using the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) -based guidelines, a literature search was conducted in Medline, Scopus, and Embase using key words such as 'medication' and 'reuse' to identify relevant articles. Two reviewers ascertained eligibility for inclusion. Inclusion criteria included English language and publication after 2010. From the articles selected, identified international medication reuse programs and relevant regulatory aspects were summarized. Details, both regulatory and operational, for the specific medication reuse programs, described in the selected articles was further explored via a grey literature search. Of the 1973 identified articles, 84 were assessed for eligibility and 17 were included in this review. Of these, 14 described scenarios where medication reuse is prohibited, 2 studies described programs allowing the reuse of medication and 1 study did not discuss whether reuse was prohibited or not. From these primary articles, secondary citations were identified, with eight from gray literature. Barriers to medication reuse included exposure to environmental extremes during storage, physical appearance, evidence of tampering, safety, and efficacy concerns for the returned medication. Programs that exist globally have overcome these barriers. Several programs that provide safe and effective reuse of medications were i© The Author(s) 2024.

The findings described in this review should be used to inform frameworks for legislative, regulatory, and professional practice change for medication reuse. Measures implemented in the UK's pandemic response to safely reuse medications in the nursing home and hospice settings and European medication donation programs should be further investigated. The concept of medication reuse is not novel and should be considered for the Australian setting.

Work experience, profession type, and perception of medication waste disposal among healthcare workers: A study in the Eastern Province, Saudi Arabia

Background

Improper disposal of medication waste is a global concern. Several published articles reported perceptions and barriers of the community or pharmacists towards proper medications waste disposal, but least are discussing the overall health workers' perception, particularly those in the Eastern Province in Saudi Arabia.

Aim and objectives

The current research aimed to identify the healthcare worker's perception, explore limitations and barriers, and proposed solutions towards proper medication waste disposal. The second aim is to investigate difference in the response among healthcare worker based on their profession type and years of work experience.

Method

This cross-sectional, descriptive study is based on an internet-based survey questionnaire. Questionnaires were adapted from previous study and were validated before distribution to participants. Respondents were classified based on their healthcare profession and based on the year of their work experience. Descriptive statistics analysis was carried out to assess difference in perception among respondents based on their profession or years of work experience. The Statistical Package for the Social Sciences (SPSS, version 26) package was used for conducting statistical analysis.

Results

321 participants responded to the online survey. 60 % of the respondents were from clinical practice settings and 26 % had work experience between 0-2 years. 77 % of them had encountered medication waste issues, whereas 129 respondents reported that these issues raised from the workplace and 92 respondents reported that they raised personal source. Interestingly, respondents with limited work experience reported the lower perception and knowledge toward mediation waste compared to those with more work experience. 31 % agreed that logistic issues (availability of collection bins) and 28 % reported that the unavailable policies/guidelines that govern this proper medication waste disposal are barriers which limit proper practice. 211 participants strongly agreed on that policies from governmental bodies are very important to limit this issue, whereas training and the availability of logistics were the most recommended solutions from respondents to increase healthcare awareness towards proper medication waste disposal.

Conclusion

Proper perception about medication waste disposal is still an ongoing issue among healthcare workers, particularly those who recently joined their work. Training and enforcing policies and guidelines by governmental bodies could be one approach to ensure proper medication waste disposal.

Health literacy, knowledge, household disposal, and misuse practices of antibiotics among UAE residents: a nationwide cross-sectional study

BACKGROUND

The study aimed to evaluate health literacy, knowledge, household disposal, and misuse practices of antibiotics among the United Arab Emirates (UAE) residents.

RESEARCH DESIGN AND METHODS

An observational cross-sectional study was conducted between May 1st and August 31st, 2022. The study encompassed a sample of 1074 participants.

RESULTS

Participants involved in a medical field (OR: 1.98, 95% CI: 1.45-2.69, p < 0.001) were more likely to have adequate health literacy. Most participants rarely (n = 315; 29.33%) or sometimes (n = 292; 27.19%) sought help from a doctor or pharmacist with reading the instructions and leaflets of antibiotics. A bachelor`s degree was associated with a reduced odds ratio of self-medication with antibiotics (OR: 0.46, 95% CI: 0.29-0.75, p = 0.002). Only 10.61% of unneeded antibiotics were returned to the pharmacy, 79.42% were disposed of at home and 10% were disposed of using other disposal practices.

CONCLUSIONS

Higher levels of adequate health literacy were observed in those involved in the medical field and those with higher educational levels. The prevalence of self-medication with antibiotics among the UAE population was low. These findings highlight the importance of improving health literacy, promoting responsible antibiotic use, and encouraging proper disposal practices among the population.

Assessment of practices and awareness regarding the disposal of unwanted pharmaceutical products among community pharmacies: a cross-sectional study in Palestine

BACKGROUND

The improper disposal of pharmaceutical preparations substantially threatens human health and environmental safety. Pharmacists are responsible for properly disposing of unwanted medications and educating patients about how to do so themselves. This study aimed to assess community pharmacists' knowledge, determine their views on how to dispose of unwanted pharmaceuticals, and assess the extent to which they realize that it is their responsibility to guide patients toward the safe disposal of expired medications.

METHODS

A descriptive cross-sectional study was conducted between December 2021 and April 2022 among 400 practicing pharmacists who were chosen to participate by random cluster sampling. Community pharmacists' practices, awareness, and beliefs about disposing of unused drugs were evaluated. The Statistical Package for Social Sciences (IBM-SPSS) version 21 was used for data entry and analysis.

RESULTS

Of 400 pharmacists, 348 stated that they did not participate in courses on the safe disposal of unwanted medications. Disposal of drugs in the garbage, an unsafe method, was very frequently recommended by pharmacists to patients, especially regarding inhalers, antibiotics, hormonal drugs, and solid and semisolid drugs. However, many pharmacists advised patients to return their hormonal, category B, and category C drugs to the pharmacy. A total of 61.3% of pharmacists agreed and 26% strongly agreed that unsafe disposal of drugs negatively affects the environment. A total of 54.3% of the participants agreed that improper disposal of antibiotics might be a reason for increased antimicrobial resistance, and 54.5% of them agreed that improper disposal of hormonal drugs might contribute to the development of certain cancers. A total of 80.3% of the participants perceived that most unwanted drugs in pharmacies were those returned from patients. A total of 97.3% of the participants supported establishing a drug disposal system, with 77.5% choosing to have the district health board responsible for funding this system. A total of 48.5% of the participants indicated that a lack of education and awareness on the issue of getting rid of unused drugs constitutes a challenge to the safe disposal of medicines, and 66% of them said that a lack of law enforcement constitutes another challenge. A total of 95.5% of the participants agreed or strongly agreed that good training for health sector workers and organizing workshops to develop knowledge on this subject would improve practices. A total of 93.3% supported distributing educational brochures, and 92.8% supported placing special containers in every pharmacy to collect unwanted drugs.

CONCLUSIONS

Most pharmacists in our study returned drugs to manufacturing companies and stores, and few followed the correct methods of incineration and return of drugs to the Ministry of Health. Current data emphasize the issue of improper disposal of medicine in Palestine and the need for improved education among healthcare workers.

Green hospital pharmacy: A sustainable approach to the medication use process in a tertiary hospital

BACKGROUND

Sustainable management of healthcare waste has a positive impact on the global environment. In order to reduce it, the sustainable practice of the pharmacotherapeutic process in all its stages is essential.

OBJECTIVE

To analyse the sustainability strategies proposed by the pharmacy service to reduce drug waste derived from the pharmacotherapeutic process.

SECONDARY OBJECTIVES

To analyse the stage of the pharmacotherapeutic process and the number and type of drugs involved.

METHODS

The study was carried out in a tertiary-level hospital. To coordinate the proposals, a referent pharmacist from every pharmacy department area was selected. Four stages of the process were evaluated (management, validation, dispensing and compounding), patients concerned were classified as outpatients or inpatients, and drugs potentially involved were analysed by the administration route: Into oral or parenteral.

RESULTS

Twenty eight ideas were proposed, which could affect more than 1200 drugs. 39.3% would affect the validation process, 17.9% the procurement management, 17.9% dispensing, and 7.1% the compounding. Implementation feasibility and acceptability of these proposals were evaluated. Those with the greatest potential were: Limiting the duration of treatments when possible, favouring the implementation of computer prescription order entry, favouring the use of the oral route over the parenteral route, and implementing computers in the preparation areas to avoid the use of paper guides.

DISCUSION

In our study, many ideas have been proposed by hospital pharmacists to improve the sustainability of the medication use process. When assessing these proposals by impact and feasibility, according to our results, shorten as much as possible the duration of treatments, computerization of the medication use process, and oral administration over intravenous should be prioritized in order to reduce environmental impact.

Modeling Predictors of Medication Waste Reduction Intention in Algeria: Extending the Theory of Planned Behavior

COVID-19 caused an increase in the demand for medications, which led to an increase in pharmaceutical waste and there is no doubt that this contributes to environmental pollution. Hence, it became necessary to search for how to protect and improve the environment by encouraging the behavior of medication waste reduction. Accordingly, this study aims to investigate the factors affecting intentions to reduce medication waste. Considering this, we develop an extended theory of planned behavior (TPB) framework by incorporating the constructs of moral obligation, environmental awareness, and medication waste risk perception. Using the convenience sampling method and based on a self-administered questionnaire, a total of 225 usable responses were collected in five Algerian cities. The results showed that positive attitudes (β = 0.316, p < 0.001), moral obligation (β = 0.291, p < 0.001), environmental awareness (β = 0.227, p < 0.001), perceived behavior control (PBC) (β = 0.151, p = 0.001), greater perceived risks (β = 0.127, p < 0.001), and subjective norm (β = 0.096, p < 0.05) significantly and positively influence the medication waste minimization intention. Furthermore, our analyses revealed that the extended TPB model explained 73.40% of the intention variance. In conclusion, we have explored the intentions, and there may be a gap between intent and actual behavior. Therefore, we recommend future studies to examine the factors affecting the actual behavior of medication waste reduction and to investigate environmental ethics and religious commitment as predictors of waste reduction intentions.

Public knowledge of antibiotics, self-medication, and household disposal practices in Jordan

BACKGROUND

This study aimed to assess public understanding of antibiotics, self-medication, and drug disposal practices.

METHODS

A cross-sectional self-administered online survey was undertaken in Jordan.

RESULTS

The study was completed by 1,105 participants. When asked about their knowledge of antibiotics, rational antibiotic use, and disposal practices, 16% percent believed they should discontinue antibiotics once they felt better, and 12% agreed to take the same antibiotics prescribed to others for the same illness. Self-medication with antibiotics was practiced by 44% of the participants. Prior experience, healthcare costs, and pharmacy location were all major determinants of self-medication. Only 6.4% of unneeded antibiotics were returned to the pharmacy, 60% were kept at home, and 26.6% were disposed of at home. Almost half of those who kept the antibiotics said they would use them again, and one-third said they would give them to friends and family. Respondents who had used antibiotics within the previous 6 months (p = 0.052) and relied on medication leaflets (p = 0.031) and physician recommendations (p = 0.001) were less likely to self-medicate with antibiotics.

CONCLUSIONS

The study highlighted areas of inappropriate use of antibiotics, self-medication and the improper antibiotic disposal that can inform antimicrobial stewardship.

Opioid Disposal Practices of Patients with Life-Limiting Cancers in an Outpatient Palliative Care Clinic: A Cross-Sectional Study

Background: Patients with life-limiting cancers are commonly prescribed opioids to manage pain, dyspnea, and cough. Proper prescription opioid disposal is essential to prevent poisonings and deaths. Objective: We examined opioid disposal practices of patients referred to a Canadian outpatient palliative care clinic (OPCC). The primary objective was to determine the prevalence of OPCC patients who did not routinely dispose their opioids. The secondary objectives were to examine their methods of opioid disposal and to identify patient characteristics associated with routine disposal of opioids. Design and Setting: This cross-sectional study involved a retrospective chart review of new, adult patients who were seen in a Canadian OPCC (September 2018-August 2019) and completed a survey about opioid-related constructs: source of prescriptions, use, storage, disposal, and knowledge about associated harms. Results: Among the 122 study participants, half (58/111, 52.3%) reported that they did not routinely dispose their opioids. The most common method of disposal was by giving them to pharmacists (69/88, 78.4%). Cannabis use (odds ratio [OR]: 3.7, 95% confidence interval [CI]: 1.1-11.8) and neuropathic medication use (OR: 3.0, 95% CI: 1.2-7.2) were positively associated with routine disposal of opioids. Conversely, reports of an increased amount of opioid use in the past six months were negatively associated with routine disposal of opioids (OR: 0.38, 95% CI: 0.16-0.88). Conclusion: The high prevalence of people with life-limiting illnesses who do not routinely dispose their opioids requires increased attention. Interventions, such as education, are needed to reduce medication waste and opioid-related harms.

Economic Cost of the Waste of Anti-inflammatory and Analgesic Drugs in Mexico City

Anti-inflammatory and analgesic medications (AAMs) are widely used in Mexico and the rest of the world. Their excessive acquisition can lead to waste, representing an unnecessary expense for families and the public health system. The aim of this study was to estimate the economic cost of the waste of unused AAMs collected by the National System for the Collection of Residues of Containers and Medications (SINGREM, the acronym in Spanish) in Mexico City during 2019. Data from SINGREM on discarded AAMs in Mexico City were classified by the type and quantity of drug, pharmaceutical dosage form, origin, dose, and the complete or incomplete condition of the package. The unitary cost for each medication was based on public tenders of the Mexican Social Security Institute (IMSS) for the public sector and the prices in large drug store franchises for the private sector. A decision-making model was constructed to appraise the total cost of discarded AAMs. The economic cost of the 48924 units of discarded AAMs in SINGREM containers in Mexico City during 2019 was approx. USD$143500, of which over USD$127000 corresponded to the private health sector. The current findings evidence an enormous accumulation of unneeded or expired AAMs in Mexico City. According to the present data, the cost of such waste is substantial. The estimated cost was 8-fold higher for discarded medications originating from the private versus the public healthcare sector. It is important to implement measures to prevent this waste and increase awareness of the consequences of inadequate drug disposal.

Impact of education on the knowledge, attitude and practice of disposal of expired and unused medications among pharmacy students

OBJECTIVE

To assess the impact of education among pharmacy students on their level of knowledge, attitude and practices in the disposal of expired and unused medications.

MATERIALS AND METHODS

A pre-test post-test study without control group was conducted in which a total of 573 students pursuing Bachelor of Pharmacy and Doctor of Pharmacy programmes were enrolled. The impact of education provided was analysed with the aid of a previously validated KAP questionnaire. Data on KAP was analysed using SPSS software 24.0.

RESULTS AND DISCUSSION

The knowledge, attitude and practice of the total students improved from 74.17±17.063 to 91.06±11.87, 75.92±19.26 to 91.73±12.318 and 43.11±22.77 to 82.06±16.149 respectively. The improvement with respect to knowledge and attitude was significantly high among Doctor of Pharmacy students when compared to Bachelor of Pharmacy, with P value<0.001 for both domains.

CONCLUSION

The present study concludes on the effectiveness of educational intervention in generating a positive impact on the student population with respective to adequate disposal practices to be followed for unused and expired medications.

Disposal of leftover and expired medicines by community pharmacies and their clients in Ghana

Improper and unsafe disposal of expired and unwanted medicines could cause harm to both people and the environment and therefore it is of public health importance. The objective of the study was to determine the methods employed by community pharmacist and their clients in the disposal of unwanted and expired medicines. Furthermore, the role of the pharmacists in the assessment of clients left over medicines was also explored. A cross sectional study design was employed with a sample of 120 pharmacy staff and 200 clients. Semi structured questionnaires were developed and administered to the two groups. Ethical approval was obtained. Data collected were analyzed using the Statistical Package for Social Sciences (SPSS v.24). Two hundred and eighty medicines were assessed from 131 respondents (65.5%) who brought their unused or left-over medicines to the pharmacy. These included analgesics 102(36.4%), antibiotics 50 (17.9%) and antacids 22 (7.9%). Disposal of expired and left-over medicines cited by respondents were the general-purpose bin 58(77.0%) and down the sink 11(14.3%). The majority 99(82.9%) of community pharmacies also disposed of solid dosage forms through the general-purpose bin. In addition, 90(75%) community pharmacies disposed of liquid waste in general purpose bin. Lack of enforcement of legislation was cited by community pharmacy staff as a barrier to the proper disposal of pharmaceutical waste. The predominant method of disposal of expired/unwanted medicines by community pharmacies and their clients was via the general-purpose bin. Implementation of interventions such as take back programmes that will enhance proper disposal of expired and left over medicines should be initiated.

Economic Analysis of Patient's Own Medication, Unit-Use and Ward Stock Utilization: Results of the First Pilot Study

BACKGROUND

Medication wastage is causing a cost burden to the healthcare system that is worth millions of dollars. An economic and ecological friendly intervention such as using a patient's own medications (POM) has proven to reduce wastage and save the cost spent by the hospital. The potential benefits of using POM in inpatient settings have yet to be explored in a country with universal health coverage. This study aimed to pilot test the POM intervention in an adult ward setting and to perform the economic analysis of using POM and ward stock during hospitalization.

METHODS

A prospective cross-sectional observational study was conducted among the patients admitted to the medical and surgical wards in a public hospital located in Brunei Darussalam between February 2022 and April 2022. Hospitalized adults above 18 years old with regular medications with a minimum length of stay of 48 h and a maximum length of stay of 21 days were included in the study. These eligible patients were divided into a POM group and a non-POM group. The economic analysis of using POM was performed by calculating the direct cost per unit of medication used during admission (from unit-use, ward stock and POM) and comparing the cost spent for both groups. Expired ward stock deemed as medication wastage was determined. Medical research ethics were approved, and all participating patients had given their written informed consent before enrolling in this study.

RESULTS

A total of 112 patients aged 63.2 ± 15.8 years participated in this study. The average cost of medication supplied by the inpatient pharmacy for the non-POM group was USD 21.60 ± 34.20 per patient, whereas, for the POM group, it was approximately USD 13.00 ± 18.30 per patient, with a mean difference of USD 8.60 ± 5.17 per patient (95% CI: -3.95, 27.47, p ≥ 0.05). The use of POM minimized 54.03% (USD 625.04) of the total cost spent by the hospital for the POM group within the period of the study.

CONCLUSION

The pilot study showed that the supplied medication cost per patient was not significantly different between the POM and non-POM groups. Nevertheless, the utilization of POM during hospitalization is capable of reducing at least 50% of the total cost spent on inpatient medications by the hospital. The use of POM during hospitalization also helped in reducing the total time spent on the medication process per patient.

Assessment of antibiotic storage practices, knowledge, and awareness related to antibiotic uses and antibiotic resistance among household members in post-conflict areas of Pakistan: Bi-central study

Background

The storage of antimicrobials at home is frequently in-practice in various developing countries, resulting an irrational use, antibiotic resistance, and toxicities. This condition may worsen more in conflict zones where health facilities are limited. This study aimed to determine the storage and use of leftover antibiotics among households (HHs) along with knowledge and awareness about antibiotics and antibiotic resistance (ABR).

Methods

A descriptive cross-sectional study design was employed. Members of HHs were invited to participate in the survey while using a convenient sampling technique. The data were obtained using a validated questionnaire and analyzed through SPSS.

Results

A total of 96 HHs were randomly selected from two districts (n = 50, n = 46), with most of the participants being men between the ages of 18 and 28 (n = 45, 46.9%) years. The majority of HHs (n = 32, 33.3%) had six to eight total family members, with one to two chronic diseases (n = 63, 65.6%), individual families (n = 60, 62.5%), and with (n = 35, 36.5%) LRTIs (lower respiratory tract infections). The HHs were aware of the word "antibiotic" (n = 59, 61.5%) and gave correct replies to amoxicillin as an antibiotic (n = 42, 43.8%); on the other hand, HHs also thought of paracetamol as an antibiotic (n = 45, 47.9%). They identified the most common brands of antibiotics easily, and a majority of them (n = 69, 71.9%) had never heard of ABR before and had lower levels of awareness. The most stored antibiotic at home (n=38, 39.6%) was azithromycin (J01FA10). In addition, they had multiple needless (1-2, n = 62, 64.6%; 3-4, n = 29, 30.2%) and antibiotics in their houses. Age had a strong association (p = 0.017, H = 12) affected the mean knowledge scores related to antibiotic use. Association of education levels (p = 0.001, H = 52.8) and occupation (p = 0.04, H = 10) with proper antibiotics use were found to be significant. However, family members with more than one chronic illness (p = 0.09, H = 0.8) showed a significant relationship with their awareness of antibiotics.

Conclusion

Participants generally stored various antibiotics of different classes in their homes. Lack of knowledge related to the appropriate usage of antibiotics, use of leftover antibiotics, and awareness related to ABR were unknown to the participants.

Assessment of knowledge, attitude, and practice of disposing and storing unused and expired medicines among the communities of Kathmandu, Nepal

Background

Unused medicines can be stored by many people at their places of residence and houses for later use. This study evaluated knowledge, and attitudes regarding unused and expired medicines and explored medicine storage and disposal practices among selected households in the Kathmandu valley, Nepal.

Method

A cross-sectional study with a two-stage cluster survey design was done using a semi-structured questionnaire from April to October 2021. The sample size (total number of households) after adjusting for design effect and non-response rate was 210 and the study population was the household heads. Simple random sampling was done to select clusters during the first stage and systematic random sampling to select households during the second stage. Descriptive statistics and t-test/one-way ANOVA were used to compare the respondents’ average knowledge scores. Practice variables were presented using frequency distribution.

Results

Around half the respondents were from the Kathmandu district, nearly 20% were from Bhaktapur and 30% were from Lalitpur. Nearly two-thirds were male and about 25% had a bachelor’s degree. Nearly 90% of respondents agreed that storage of excess medicines at home may promote self-medication. Similarly, 97.6% of respondents agreed there is a lack of adequate information on the safe disposal of unused medicines. The majority [125 (59.5%)] of participants always checked the expiry date of medicines. The safe methods of medicine disposal were not known by 137 (65.2%) participants. Throwing in a dustbin was the preferred method of expired medicine disposal.

Conclusion

The level of knowledge and practice of disposing of unused and expired medicines requires improvement. Educational interventions may help improve awareness further. Creating a chart summarizing disposal procedures of common medicines is important. Similar studies in other regions are required.

Does Sustainable Consumption Matter? The Influence of the COVID-19 Pandemic on Medication Use in Brasov, Romania

Sustainable consumption refers to the choice, purchase, use, and disposal of goods so as to enable all people to meet their present and future objective needs. However, panic caused by the gradual onset of the pandemic had a considerable impact on the behavior of consumption and purchase of medication, and the question remains whether sustainable consumption still matters during a crisis or not. The present study aims to analyze whether the pandemic has influenced the behavior of medication use among residents of Brasov County amid panic caused by the virus and to determine the primary sources of information on methods of the prevention and treatment of health conditions. The study focusses on the differences between the two target groups, young people, and adults, considering three socio-demographic factors, such as age, gender, and background. The present research uses two methods of data collection: an interview with 5 doctors and a questionnaire with 543 respondents. This research draws attention to the fact that the behaviors of purchasing and consuming medication during the COVID-19 pandemic has changed due to the spreading of the new virus and the state of emergency, as well as with medication use becoming less sustainable. The results showed that adults were more engaged in the panic buying of medication compared to young people during the pandemic; however, in normal times, young people use more medication. Our study shows that females tend to consume more medicines than males. Moreover, they are more susceptible for seeking media guidance and following advice from the digital realm, because they avoid going to the doctor, especially during the COVID-19 period. Depending on the environment of residence, it was found that people in rural areas generally tend to consume more medication than those in urban areas. However, during the pandemic, the drug use of this category of population has decreased because they do not tend to self-medicate and avoid visiting the doctor because of the fear of becoming contaminated. The results of the research could help to establish measures in order to prevent the panic buying of self-medication and pharmaceuticals, both during pandemics and in normal times, because such behaviors can have negative effects on both health and the environment.

Analysis of factors contributing to medication errors during self-management of medication in the rehabilitation ward: a case control study

Background

In the rehabilitation ward, many elderly patients require continuous use of medication after a stroke or bone fracture, even after discharge. They are encouraged to self-manage their medications from the time of admission. Medication errors, such as a missed dose or incorrect administered medication can worsen conditions, resulting in recurrent strokes, fractures, or adverse effects. The study was aimed to identify risk factors, such as medication and prescription, contributing to errors in self-management of medication.

Methods

This study was conducted on patients who self-managed their medication in the rehabilitation ward of Higashinagoya National Hospital from April 2018 to March 2020. The patient background including age and sex were investigated. The medication factors examined include the number of medications and administrations per day, dosing frequency on indicated days, prescription and start date are the same, medications from multiple prescriptions, and one package or one tablet at each dosage. The group of medication error cases were defined as the medication error group and that of control cases as the no-medication error group. A logistic regression analysis was performed for factors related to medication errors.

Results

A total of 348 patients were included in the study, of which 154 patients made medication errors, with 374 total medication error cases. The median number of medications in the medication error group was six, and that in the no-medication error group was five. Statistically significant factors correlated with errors made during self-management of medication were the number of medications, number of administrations per day, dosing frequency on indicated days, and medication from multiple prescriptions.

Conclusions

When a patient is self-managing their medications, errors are likely to occur due to a high number of medicines they are taking and the complexity of the dosage regimen. Therefore, to prevent medication errors, reviewing the prescribed medications and devise ways to simplify the dosage regimens is crucial.

Analysis of medicines returned to pharmacies for disposal and estimation of the cost due to medicine wasting

Background

Studies have shown that waste medicines generate a significant cost for the national health system (NHS) in many countries. No data are available on costs and therapeutic classes of unused medicines in Italy.Objective: Conduct a quantitative and qualitative analysis of unused medicines returned for disposal to selected pharmacies in Rome, Italy, as well as to estimate the related costs for the NHS.

Methods

Medicines returned to 4 pharmacies were collected for 8 months. Therapeutic class, number of remaining dosage units, remaining validity, and reimbursement by the NHS were analysed. The cost of reimbursed medicines was estimated on the prices provided by the Italian regulatory agency (AIFA).

Results

The study sample consisted of 3219 medicine packages containing remaining dosage units, of which 72.4% had expired while 27.6% had not. The average remaining validity of unexpired medicines was 13 months. Medicines reimbursed by the NHS accounted for 73% of the total. Cardiovascular drugs and anti-infectives were the main therapeutic classes (17.2% and 15.2% of total packages, respectively), followed by gastrointestinal drugs, central nervous system (CNS) drugs, non-steroidal anti-inflammatory drugs (NSAIDs), and corticosteroids. The average of remaining dosage units found in the examined packages was 68% of the initial number of units. In terms of cost, antibiotics were the most relevant therapeutic class, followed by cardiovascular drugs, analgesics, corticosteroids, and NSAIDs. The estimated cost for the Italian NHS was € 200,656,780 per year.

Conclusion

Waste medicines constitute a significant, but reducible cost for the NHS. The high prevalence of anti-infectives in the study sample appears to be a distinctive Italian characteristic and may be due to inappropriate prescribing. Policies aimed at reducing waste should improve prescriptive appropriateness and increase the variety of packaging size.

Issues on Powder Forms for Oral Solution and Suspension for Pediatric Patients in Japan: A Questionnaire-Based Observational Survey to Pediatric Pharmacists

BACKGROUND

Powders for oral solutions and suspensions (POS) are commonly used as pediatric oral medicines worldwide, except for Japan. Although global pediatric formulation development accelerates POS importation to Japan without any formulation change, oral solid multiparticulates remain to be the preferred pediatric forms in the country. This study aimed to evaluate the acceptance situation of four typical POS form products (mycophenolate mofetil, sildenafil citrate, valganciclovir hydrochloride, and voriconazole) that were recently approved in Japan.

METHODS

A questionnaire on four products was completed by pharmacists in 29 children's hospitals with more than 100 beds each, between November and December of 2019. The questionnaire has six items on (#1) type of institution, (#2) formulary status, (#3) dispensing practice, (#4) reasons why POS form(s) were not selected as hospital formulary, (#5) advantages and disadvantages of POS form, and (#6) opinions for POS form.

RESULTS

Of the 29 institutions, 7 (24%), 9 (31%), 4 (13%), and 10 (34%) institutions used POS of mycophenolate mofetil, sildenafil citrate, valganciclovir hydrochloride, and voriconazole, respectively. Reasons for not using these products were dispensed drug loss, formulation issues, and management issues in the pharmaceutical department and pediatric ward. Pharmacists preferred drug compounding such as tablet crushing and capsule opening to POS form use.

CONCLUSIONS

POS forms might be an unsuitable formulation for the current hospital settings in Japan. Thus, appropriate dosage forms that reflect the current clinical settings are necessary.

Patients' knowledge and practice on disposal of medicines kept in households in South Africa: Findings and implications

Objective:

The disposal of unwanted, unused, or expired medicines is a concern. Currently, there is little knowledge regarding their disposal among patients in South Africa. Consequently, there is a need to address this.

Methods:

This was a descriptive and quantitative study with patients conducted among 16 primary health-care clinics (PHCs) in South Africa. A structured questionnaire was administered to 171 conveniently selected patients. Data on ideal disposal methods were collected and compared to actual disposal practices.

Findings:

74.9% of patients reported having unused medicines at home, of whom 34.4% wanted these medicines disposed of. However, 64.9% did not know how to dispose of them, with 95.3% reporting having never been informed by health-care professionals of disposal methods. While patients prefer to return medicines to their PHC, only 7.0% did so. Patients’ ideal disposal practices included designated collection task teams (25.1%) and dissolving their unused medicines in water (38.6%). However, current practices indicated that patients flushed medicines down the sewer (31.6%) or disposed of them in municipal bins (23.9%).

Conclusion:

Patients disposed of their unwanted medicines using incorrect disposal techniques, which they thought were correct. This urgently needs to be addressed.

Disposal practice and factors associated with unused medicines in Malaysia: a cross-sectional study

Background

The improper disposal of unused medicines is a worldwide concern because of its impact on the environment, economy, and health. This study aims to describe the disposal practice of unused medicine and identify factors associated with unused medicines in Malaysia.

Methods

This was a cross-sectional, face to face interview-based survey using a structured questionnaire. We used a convenience sampling method to recruit participants from Kuala Lumpur and Selangor in Malaysia.

Results

We interviewed 1184 participants, and the response rate was 96%. Out of the total respondents, 995 (84%) reported having unused medicines. About a quarter of respondents kept unused medicines in the cabinet, and another quarter disposed of them into the trash or toilet. Only half of the respondent who used medicines for chronic illnesses had unused medicines compared to about 90% of respondents who used medicines for acute illnesses. The main reason for having unused medicines among those who used medicines for chronic illness was non-adherence (69%, p <  0.05). Only 27% of these respondents returned unused medicines under the “Medicine Return Programme (MRP)”. The other group who used medicines for acute illnesses had unused medicines because their health conditions improved. Thus, most of the unused medicines will eventually end up in household waste. A multivariate logistic regression analysis identified respondents who used medicines for acute illnesses as the strongest predictor of having unused medicines (Odds Ratio (OR) = 29.8; p <  0.001), followed by those who pay for their medicines (OR = 6.0; p < 0.001) and those who were willing to participate the Medicine Return Programme (OR = 2.5; p = 0.009).

Conclusion

The prevalence of unused medicines and their improper disposal were high in Malaysia. Unused medicines are associated with people who use medicines for acute illnesses, pay for their medication, and are willing to participate in an MRP. Rationale prescription and optimal dispensing practice, together with a broader MRP facilities coverage, could reduce unused medicine possession.

A systematic assessment of the epidemiologic literature regarding an association between acetaminophen exposure and cancer

Introduced in the 1950s, acetaminophen is one of the most widely used antipyretics and analgesics worldwide. In 1999, the International Agency for Research on Cancer (IARC) reviewed the epidemiologic studies of acetaminophen and the data were judged to be "inadequate" to conclude that it is carcinogenic. In 2019 the California Office of Environmental Health Hazard Assessment initiated a review process on the carcinogenic hazard potential of acetaminophen. To inform this review process, the authors performed a comprehensive literature search and identified 136 epidemiologic studies, which for most cancer types suggest no alteration in risk associated with acetaminophen use. For 3 cancer types, renal cell, liver, and some forms of lymphohematopoietic, some studies suggest an increased risk; however, multiple factors unique to acetaminophen need to be considered to determine if these results are real and clinically meaningful. The objective of this publication is to analyze the results of these epidemiologic studies using a framework that accounts for the inherent challenge of evaluating acetaminophen, including, broad population-wide use in multiple disease states, challenges with exposure measurement, protopathic bias, channeling bias, and recall bias. When evaluated using this framework, the data do not support a causal association between acetaminophen use and cancer.

Medicine storage, wastage, and associated determinants among urban households: a systematic review and meta-analysis of household surveys

Background

Irrational household storage of medicines is a world-wide problem, which triggers medicine wastage as well as its associated harms. This study aimed to include all available evidences from literature to perform a focused examination of the prevalence and factors associated with medicine storage and wastage among urban households. This systematic review and meta-analysis mapped the existing literature on the burden, outcomes, and affective socio-economic factors of medicine storage among urban households. In addition, this study estimated pooled effect sizes for storage and wastage rates.

Methods

Household surveys evaluating modality, size, costs, and affective factors of medicines storage at home were searched in PubMed, EMBASE, OVID, SCOPUS, ProQuest, and Google scholar databases in 2019. Random effect meta-analysis and subgroup analysis were used to pool effect sizes for medicine storage and wastage prevalence among different geographical regions.

Results

From the 2604 initial records, 20 studies were selected for systematic review and 16 articles were selected for meta-analysis. An overall pooled-prevalence of medicine storage and real wastage rate was 77 and 15%, respectively. In this regard, some significant differences were observed between geographical regions. Southwest Asia region had the highest storage and wastage rates. The most common classes of medicines found in households belonged to the Infective agents for systemic (17.4%) and the Nervous system (16.4%). Moreover, income, education, age, the presence of chronic illness, female gender, and insurance coverage were found to be associated with higher home storage. The most commonly used method of disposal was throwing them in the garbage.

Conclusions

Factors beyond medical needs were also found to be associated with medicine storage, which urges effective strategies in the supply and demand side of the medicine consumption chain. The first necessary step to mitigate home storage is establishing an adequate legislation and strict enforcement of regulations on dispensing, prescription, and marketing of medicines. Patient’s pressure on excessive prescription, irrational storage, and use of medicines deserve efficient community-centered programs, in order to increase awareness on these issues. So, hazardous consequences of inappropriate disposal should be mitigated by different take back programs, particularly in low and middle income countries.

Development, translation, and validation of a bilingual questionnaire on unused medications in homes

Background

Unused medications in homes pose significant health, economic, and environmental risks. Patients are the medications end users and their knowledge, attitude, and practices (KAP) play an important role towards medication use, unuse and wastage. Thus, a valid instrument to reliably measure patients’ KAP towards unused medications in homes may help manage the associated risks.

Objective

To develop, translate, and validate a questionnaire for the assessment patients’ KAP towards unused medications in Qatar homes (i.e., QUM-Qatar).

Setting

This cross-sectional validation study was conducted among randomly selected outpatients visiting various public and private pharmacies in Qatar between September 2019 and February 2020.

Method

Nine experts in the field of pharmacy practice with Qatar contextual background established the content validity of the instrument. The validity was quantified using content validity index (CVI). Furthermore, construct validity was performed using principal component analysis (PCA), whereas internal consistency reliability of items was determined using Cronbach’s alpha. Statistical analyses were performed using STATA 15 statistical software.

Main outcome measure

The psychometric properties of the QUM-Qatar assessment instrument.

Results

An English/Arabic questionnaire was developed and validated. Content validity in the form of scale-level-CVI (S-CVI)/Average and S-CVI/UA was 0.88 and 0.84, respectively, suggesting adequate relevant content of the questionnaire. Variation explained by the multivariate model was 85.0% for knowledge, 94.8% for attitude, and 89.8% for practice. Cronbach’s alpha coefficients were 0.68, 0.82, and 0.84, for knowledge, attitude, and practice domains, respectively. From the psychometric results obtained, the questionnaire's validity and reliability were attained.

Conclusion

The QUM-Qatar instrument has acceptable psychometric properties and has the potential for future use in research and practice to assess KAP towards unused medications in Qatar and elsewhere. It may consequently help in improving medication use and mitigating the negative health, economic, and environmental impacts of unused medications.

Impacts on practice.•

There is now a valid and reliable English/Arabic language questionnaire to assess patients’ KAP towards unused medications.

•

Policymakers can utilize this questionnaire to develop evidence-based policies and strategies for managing unused medications and their disposal.

•

To improve medication use review, rational use of medicines, and adherence, it is necessary to consider patient-reported outcomes that may eventually reflect on saving health, economic resources, and environment.

Lack of Awareness of the Impact of Improperly Disposed Of Medications and Associated Factors: A Cross-Sectional Survey in Indonesian Households

Introduction: Disposal of unused medications through environmentally unsafe routes is common in Indonesia. The lack of awareness of the impact of improperly disposed of medications is a significant contributing factor. The objectives of this study were to identify factors associated with lack of awareness of the impact of improperly disposed of unused medications and to assess the associations of awareness with medication disposal practices among the general population in Indonesia.

Patients and methods: An observational cross-sectional survey was conducted using nonprobability sampling in Bandung, Indonesia, from November 2017 to January 2018 among respondents who were older than 18 years, had used any medication in the past, were literate, and had signed an informed consent document. Disposal practices and awareness regarding the impact of improperly disposed of unused medications were collected using an online- and a paper-based pre-validated questionnaire. The paper-based questionnaires were distributed to respondents in public places such as city center, markets, and religious places. Binary logistic regression was performed to assess associations of sociodemographic and other related factors with a lack of awareness. Odds ratios (ORs) with 95% confidence intervals (CIs) are reported.

Results: Of 497 participating respondents, 433 and 64 respondents filled an online- or a paper-based questionnaire, respectively. Most respondents were female, aged between 18 and 30 years, and students/university students. Of 497 respondents, more than half (53.1%) were not aware that improper medication disposal could harm the environment and population health. Most respondents (79.5%) had never received information about proper medication disposal practices. The education level, the number of stored medications at home, and previous education about medication disposal practices were significantly associated with awareness of proper practices. In the multivariate analysis, only those with previous education about medication disposal practices were less likely to report a lack of awareness (OR: 0.043; 95% CI: 0.02–0.09). Respondents with a lack of awareness tended to dispose of their unused medications in the garbage or shared them with friends or relatives.

Conclusion: There is a clear need to increase awareness of the importance of proper medication disposal practices, in particular among the student population of Bandung city, Indonesia. Healthcare providers can play an important role by educating this specific population on the proper disposal of unused medications.

Public Attitudes towards Medicinal Waste and Medicines Reuse in a 'Free Prescription' Healthcare System

This study investigates public attitudes towards medicinal waste and medicines reuse within a ‘free prescription’ healthcare system. A quantitative online survey was employed in a sample drawn from the population of Wales, where prescription medicines have been ‘free’ since 2007. Qualitative interviews informed the content of the attitude statements with categorical or ordinal response options assigned. The questionnaire was hosted on the HealthWise Wales platform for 1 year from October 2017. Of the 5584 respondents, 67.2% had at least one medicine on repeat prescription. Overall, 89.1% held strong concerns about medicinal waste. High acceptance for the reuse of prescription medicines which have been returned unused by patients to pharmacies was reported for tablets (78.7%) and capsules (75.1%) if the medicine is checked by a pharmacist first (92.4% rated essential). Concerns identified related to tampering of packs (69.2%) and the need for hygienic storage (65.4%). However, those working in healthcare had less concern about the safety of reusing medicines. The level of public acceptance for the reuse of medication was higher than previously reported. This is the largest survey to capture these views to date, which has implications for the future design of medicines reuse schemes.

Medications disposal and medications storage in Jordan: A cross-sectional study

AIMS

Many concerns arise from the improper disposal of medications, which is associated with a negative impact on health and wildlife. The majority of the consumers of pharmaceutical products remain unaware of the procedures of disposal of unused or expired medicines. This study aimed to explore the practices of Jordanian individuals regarding the disposal and storage of unused or expired medications.

METHODS

A cross-sectional study was conducted in Jordan for the period between July and November 2019 of patients who reported having unused, leftover or expired medications in their homes. The questionnaire tool was constructed based on a number of studies concerning medication recycling and international guidelines about correct and safe disposal of expired, unwanted or unused medication.

RESULTS

A total of 1092 participants were included in the study. Their mean age was 32.4 (SD = 13.6) years and 56.8% (n = 620) were males. More than half of the participants (58.1%, n = 634) reported that they had unused, leftover or expired medications in their homes. The bedroom, kitchen and store room were the three most commonly reported places for the storage of unused, leftover or expired medications. The pharmacist was the main source for information regarding the storage of medications. The three most common reasons reported by the participants regarding having unused/leftover medications at home were change or discontinuation by the doctor (29.4%), self-discontinuation as the illness symptoms improved or resolved (28.2%) and forgetfulness (25.1%).

CONCLUSION

A high percentage of the Jordanian population improperly handles their unused, leftover or expired medications. More restrictions are needed on the prescribing and dispensing of medications by the authorities concerned and there is a need to establish public guidelines regarding the use and correct disposal of pharmaceuticals.

What medicines do households keep in their cabinets? Understanding the possession and use of medicines at home and the role of health insurance in Nigeria

Background

Globally, the possession of medicines stored at home is increasing. However, little is known about the determinants of possessing medicines, their usage according to clinical purpose, which we term ‘correct drug match’, and the role of health insurance.

Methods

This study uses data from a 2013 survey evaluating a health insurance program in Kwara State, Nigeria, which upgraded health facilities and subsidized insurance premiums. The final dataset includes 1,090 households and 4,641 individuals. Multilevel mixed-effects logistic regressions were conducted at both the individual level and at the level of the medicines kept in respondents’ homes to understand the determinants of medicine possession and correct drug match, respectively, and to investigate the effect of health insurance on both.

Results

A total of 9,266 medicines were classified with 61.2% correct match according to self-reported use, 11.9% incorrect match and 26.9% indeterminate. Most medicines (73.0%) were obtained from patent proprietary medicine vendors (PPMVs). At 36.6%, analgesics were the most common medicine held at home, while anti-malarial use had the highest correct match at 96.1%. Antihistamines, vitamins and minerals, expectorants, and antibiotics were most likely to have an incorrect match at respectively 35.8%, 33.6%, 31.9%, and 26.6%. Medicines were less likely to have a correct match when found with the uneducated and obtained from public facilities. Enrolment in the insurance program increased correct matches for specific medicines, notably antihypertensives and antibiotics (odds ratio: 25.15 and 3.60, respectively).

Conclusion

Since PPMVs serve as both the most popular and better channel compared to the public sector to obtain medicines, we recommend that policymakers strengthen their focus on these vendors to educate communities on medicine types and their correct use. Health insurance programs that provide affordable access to improved-quality health facilities represent another important avenue for reducing the burden of incorrect drug use. This appears increasingly important in view of the global rise in antimicrobial resistance.

Knowledge and Practice on Ecopharmacovigilance and Medicine Storage Amongst Medical and Dental Students in Lalitpur, Nepal

Background

Medicines may remain unused and often get expired. Unused medicines can promote self-medication. Unsafe and improper medicine disposal can cause significant environmental harm. Medical and dental students as future prescribers should be aware of the safe disposal of medicines, ecopharmacovigilance and self-medication. The present study examines knowledge and practice about unused and expired medicines and medicine disposal among undergraduate medical and dental students in Nepal.

Methods

The study was conducted during September 2020 using an online survey form. First to final year undergraduate students provided their consent and signed an integrity pledge electronically. Age, gender, program of study, year of study, whether staying with family or not, method of financing education, and whether they had used any allopathic medicines during the past 6 months were noted. The total knowledge score among different subgroups was compared. The frequency of responses regarding practice items and the free-text comments were also listed. Statistical analysis was performed using Mann–Whitney test and Kruskal–Wallis test.

Results

Altogether 441 of the 668 students (66%) participated. The majority were below 23 years and female. Over 65% had used allopathic medicines during the last 6 months. The median knowledge score was 8 (maximum 10) and was significantly higher among older respondents, females and students in later years of study. Most kept unused medicines at home/hostel till expiry which were disposed of in the household garbage. Over 40% had educated their family members about safe medicine disposal. Knowledge scores were significantly different among subgroups according to respondents’ age, gender and year of study.

Conclusion

Respondents were aware of expiry of medicines and knew methods to safely dispose expired medicines. However, they practiced self-medication, stored medications at home and did not practice the safe disposal of medications. Understanding why respondents did not dispose medicines properly is important.

Towards Medicines Reuse: A Narrative Review of the Different Therapeutic Classes and Dosage Forms of Medication Waste in Different Countries

BACKGROUND

Medicines reuse, the idea of re-dispensing returned medicines to others following quality control, is yet to be implemented in the UK. This practice is potentially a sustainable way of dealing with returned medicines, which are otherwise classed as medication waste and destroyed. To inch towards medicines reuse, it is important to know more about the different therapeutic classes and dosage forms that make up medication waste. For example, it is helpful to know if medicines being returned are mostly solid-dosage forms and thus have the potential to be reused or are from therapeutic classes that would make medicines reuse cost-effective. Little is known about the therapeutic classes and the dosage forms of wasted medicines. This study aimed to narratively review and report findings from the international literature on the different therapeutic classes and the dosage forms of medicines that are returned by patients to community pharmacies, hospitals, general practitioners' clinics, or collected through waste campaigns. Studies based on surveys without physically returning medicines were also included where relevant.

METHODS

A comprehensive electronic search of databases, including PubMed and Google Scholar, was carried out over one month in 2017 and updated by 5 November 2020, using a combination of carefully created keywords.

RESULTS

Forty-five studies published in English between 2002 and 2020, comprising data from 26 countries were included and reviewed. Oral solid dosage forms (mostly tablets) were the commonly reported dosage form of all wasted medicines in 14 studies out of the 22 studies (64%) that described the dosage form, with percentages ranging from 40.6% to 95.6% of all wasted medicines. Although there was variability among the levels of medication waste reported in different countries, findings from the UK and Ethiopia were relatively consistent; in these, medicines for the cardiovascular system and anti-infective medicines, respectively, were the most common therapeutic classes for medication waste.

CONCLUSION

This narrative review provides insights about the different therapeutic classes and dosage forms of medication waste either returned by patients, collected through waste campaigns, or indicated in survey responses. The findings could help policy makers understand the potential implications of treating most unused medicines as medication waste and whether therefore pursuing a medicines reuse scheme could be environmentally or financially logical. The quality and the safety of these returned medicines using criteria related to the storage conditions (such as heat and humidity), physical shape (such as being sealed, unopened, unused, and in blister packaging), and tampering are other important considerations for a medicines reuse scheme.

Can We Create a Circular Pharmaceutical Supply Chain (CPSC) to Reduce Medicines Waste?

BACKGROUND

The increase in pharmaceutical waste medicines is a global phenomenon and financial burden. The Circular Economy, as a philosophy within the pharmaceutical supply chain, aims to promote waste reduction, maximise medicines value, and enable sustainability within this supply chain (increasing circularity). Circularity strategies for pharmaceuticals are not currently implemented in many countries, due to quality and safety barriers. The aim of this study was to determine whether the application of circular economy principles can minimise pharmaceutical waste and support sustainability in the pharmaceutical supply chain; Methods: a detailed narrative literature review was conducted in order to examine pharmaceutical waste creation, management, disposal, and the application of circular economy principles; Results: the literature scrutinised revealed that pharmaceutical waste is created by multiple routes, each of which need to be addressed by pharmacists and healthcare bodies through the Circular Economy 9R principles. These principles act as a binding mechanism for disparate waste management initiatives. Medicines, or elements of a pharmaceutical product, can be better managed to reduce waste, cost, and reduce negative environmental impacts through unsafe disposal.

CONCLUSIONS

the study findings outline a Circular Pharmaceutical Supply Chain and suggests that it should be considered and tested as a sustainable supply chain proposition.

Prevalence and Practice of Unused and Expired Medicine-A Community-Based Study among Saudi Adults in Riyadh, Saudi Arabia

Purpose

The objective of the current study was to determine the prevalence and practice of unused and expired medicine among Saudi adults. Subjects and Methods. The study used cross-sectional web-based design to collect the data, over a period of 4 months among people who are living in Riyadh, Saudi Arabia.

Results

A total of 337 questionnaires were obtained during the study period. The majority of respondents were university graduates n = 251 (74.7%). The prevalence of unused medicine was n = 301 (89.3%). The most commonly used drugs were nonsteroidal anti-inflammatory drugs n = 272 (80.7%) and antibiotics n = 164 (48.7%). Of the participants, 186 (55.2%) checked the expiry date of the medicine before they purchase. Most of them n = 305 (90.5%) obtained medicine through prescription. About n = 219 (65%) of them keep the medicine until it expired; 48.1% throw away in the household garbage while only 18 (5.4%) of the respondents said to give it back to the medical store.

Conclusion

The study revealed a high prevalence of unused medications among Saudi community. However, the disposable practice among the Saudi community was inadequate. Increasing awareness through education programs about proper disposable guidelines is necessary for controlling the medication wastage.
