Knowledge and Disposal Practice of Leftover and Expired Medicine: A Cross-Sectional Study from Nursing and Pharmacy Students' Perspectives

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.

Evaluation of clinical knowledge of drugs causing addiction and associated social determinants among male pharmacy and nursing students in Riyadh, Saudi Arabia - A Cross-Sectional study

Drug abuse is a rising psychological concept in many countries, and its use among individuals is increasing. Therefore, this study aimed to assess the Knowledge and demographic factors associated with drug abuse among male pharmacy and nursing students at King Saud University, Riyadh, Saudi Arabia. This study used a cross-sectional design targeting male entry-level pharmacy and nursing students in their first and second years of Bachelor of Nursing and Doctor of Pharmacy courses. Of them, 85.3 % of the pharmacy and 75.3 % of nursing students thought that cocaine causes drug addiction, followed by heroin (pharmacy 80.7 %; nursing students 71 %), and morphine (pharmacy 75.2 %; nursing students 59.1 %). In this study, 52 % (n = 105) claimed low awareness, whereas 48 % (n = 97) indicated good understanding regarding drug addictions. Furthermore, the mean knowledge score among pharmacy students was higher (7.073 ± 2.570) in comparison to nursing (5.806 ± 2.494) (t = 3.540; p = 0. 0001). In addition, the father's occupation was found to be significantly associated with the mean knowledge score of drug addiction (F = 2.667; p = 0.034). According to the findings, 52 % of male students had insufficient knowledge about drugs that cause addiction. Age, course of study, and father's occupation all had a substantial impact on knowledge scores. The knowledge score on the complications of addictive substances was not significantly associated with the characteristics of the students (p = 0.05). As a result, we advocate for the introduction of educational initiatives that educate students about the harmful consequences of drug addiction and how to avoid issues.

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.

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

Background

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

Methods

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

Results

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

Conclusion

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

Evaluation of Headache Trends among Undergraduate First Responders for Medical Emergencies at Saudi University in Riyadh, Saudi Arabia

Background and objective: Headache is more common among students and may be a crucial indication of mental health; it can have a detrimental impact if left untreated, especially on students, and may affect their academic performance. Thus, this study aimed to assess the headache trends among undergraduate first responders for medical emergencies at Saudi University in Riyadh, Saudi Arabia. Method: A cross-sectional study was undertaken over three months in 2023 to analyze headache patterns among emergency medical services (EMS) students using prevalidated questionnaires. The data were collected via convenience sampling and processed with the IBM SPSS Statistics 26 program (IBM Inc., Chicago, IL, USA). Results: The current findings show that the majority 90.6% (n = 164) of the participants had at least one episode of headache in the last week. With regard to the number of days students had a headache during the last week, 21.5% (n = 39) of them reported 2 days, while 18.8% (n = 34) reported 1 day only. About slightly less than half (48.6% (n = 88)) of students reported that the usual site of the headache was frontal, followed by temporal 27.1% (n = 49), and 23.3% (n = 42) reported orbital. When students were asked whether a headache aggravates their routine activity, 40.3% agreed with this statement, and 44.2% of students reported that a headache causes them to avoid their routine activity (reading writing, attending college). The majority of the students considered taking analgesics (60.8%), followed by sleeping (26.5%), caffeine (14.4%), and herbal and alternative remedies (7.7%) for the relief of headaches. Although headache episodes were significantly associated with routine activities (reading writing, attending college) (p = 0.018, t = 2.282) daily activities (walking, running) (p = 0.022, t = 2.307). The findings showed that fourth-year EMS students were found to have higher headache pain intensity scores compared to other students (p = 0.046). Similarly, the pain intensity was significantly higher among the students between 1-3 and >7 episodes of headaches (p = 0.001) Conclusion: The findings of this study revealed that Saudi emergency medical services students suffer from headaches. However, the current findings revealed variation in the headache pain intensity scores concerning the year of study.

Assessment of the magnitude and contributing factors of expired medicines in the public pharmaceutical supply chains of Western Ethiopia

BACKGROUND

The magnitude of expired medicines in supply chains are increasing globally due to lack of strict control of the supply chain, poor storage management and oversupply of medicines. This situation is very serious in resource-poor countries, including Ethiopia, where the supply of medicines is limited. Therefore, this study aimed to assess the magnitude and the contributing factors of expired medicines in the Public Pharmaceutical Supply Chains of Western Ethiopia.

METHODS

Explanatory sequential study design involving mixed quantitative and qualitative approach were employed among 62 public pharmaceutical supply chains of Western Ethiopia from July1 to August 30, 2021. An observational checklist and the self-administered questionnaire were used to review all records of the expired medicine file and to abstract secondary data on the extent, types of expired medicines and its contributing factors. The collected data was cleared, filtered, and coded using Microsoft Excel® 2010, and exported to SPSS version-23 (Amsterdam, Netherland) for statistical analysis. Bivariate logistic regression was used to check association between the outcome and independent variables. Multivariate logistic regression was analyzed when p-value is less than or equal to 0.25 in bivariate binary logistic regression, considering the statistical at p-value < 0.05. Moreover, audio recordings were transcribed and coded for emergent themes using thematic analysis.

RESULTS

The study revealed 5% expire rate over past two financial (2012 up to 2013) years and the total amount of expired drugs is estimated at 20 million Ethiopian Birr (ETB). Tetanus antitoxin (TAT), in terms of single drug value, had the highest drug expiry (4,110,426.43ETB: 20%), followed by liquid dosage forms (11,614,266.11 ETB: 57%). The Binary logistic regression result indicated that, poor store management were more likely associated with the magnitude of expired medicine than those with good store management (COR: 10.706, 95% CI: 2.148, 53.348). Multivariate logistic regression revealed that poor store management (AOR: 9.718, 95% CI: 1.474, 64.082) was a significant contributor to the expire rate at 5% (P < 0.05). Most facilities did not have a procedure, and programme for disposing of expired medicines. According to key informants, inadequate inventory management, lack of policy and implementation of standards are the main contributing factors of the medicine's expiration.

CONCLUSION AND RECOMMENDATIONS

The current study found that the overall rate of medication expiration is high, at a significant cost to the budget. Inadequate inventory management, lack of policy, and implementation of standards are the main contributing factors to the medicine's expiration, as cited by key informants. Further research is necessary to determine the quality and efficacy of these expired drugs to extend their shelf life to ensure adequate access to drugs in resource-limited settings.

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.

Assessment of Headache Characteristics, Impact, and Managing Techniques among Pharmacy and Nursing Undergraduates-An Observational Study

Background and Objectives: Many different forms of headaches can change or impact daily activity and quality of life, which increases the financial burden on society over time. Undergraduates who get headaches may be absent from attending lectures, perform less well on their daily tasks and academic achievement, as well as struggle to build and maintain relationships with peers and mentors. Therefore, this study aimed to assess the headache-related characteristics and managing approaches among Saudi pharmacy and nursing students at a Saudi university, in Riyadh, Saudi Arabia. Materials and Methods: A survey questionnaire was administered in this cross-sectional study to participants at a Saudi university, in Riyadh, Saudi Arabia. Participants included males. The sample size was calculated with Raosoft® software. Data analysis was executed using IBM Statistic SPSS, and the level of statistical significance was set at p < 0.05. Results: A total of 236 participants completed the questionnaires. The majority, i.e., 218 (92.4%) of them, were male; in addition, 124 (52.5%) were aged between 26 and 30, 124 (52.5%) were pharmacy students, 112 (47.5%) were nursing students, and 134 (56.8%) were smokers. When asked about ever having at least one episode of headache during the week, 66.1% (n = 156) agreed that they had one episode of headache, although 57 (24.2%) of the students had a headache for five days during a week. With regard to the impact of headaches on everyday activities, only 34.7% of the students said that headache disrupted their regular activities. Almost 41% of the students agreed that headache impacted their academic performance. Nearly 34% of students (n = 79) who had headaches considered napping, while 33% (n = 64) took painkillers and anti-inflammatory medicines, and 25% (n = 59) considered taking caffeine. In this study, the participants’ ages and headache severity were strongly associated (p = 0.0001). More pharmacy students (66.1%) reported having severe headaches than nursing students (14.3%) (p = 0.0001). Conclusions: The current findings revealed that most of the undergraduates suffered from headaches, and the intensity of the pain was moderate; furthermore, one in four undergraduates reported that headaches impacted their academic performance. Caffeine and simple analgesics and anti-inflammatories were used for headache relief.

Al-Rawi M. Evaluation of knowledge of risk factors and warning signs of stroke - An observational study among future health care professionals

Background and objective

The role of healthcare professionals in society is unique since they are providers of health information and medication counseling to patients. Hence, this study aimed to evaluate Knowledge of Risk Factors and Warning Signs of Stroke among undergraduate health care Students (UHCS) at King Saud University (KSU), Riyadh, Saudi Arabia.

Methodology

An online cross-sectional study was conducted among UHCS at KSU, Riyadh, Saudi Arabia from September to November 2022, using self-administered 34-item questionnaires divided into five sections to assess participants' knowledge of stroke risk factors, warning signs, and management and source of information about the stroke. The Statistical Package for the Social Sciences version 26 was used to analyze the data (SPSS).

Results

Of the 300 questionnaires distributed, 205 students completed the questionnaires, giving a response rate of 68.3%. Of whom 63 (30.7%) were pharmacy, 81 (39.5%) were nursing and 61 (29.8%) were emergency medical services (EMS) Students. One hundred and eighty-two (88.8%) of the students agreed that stroke affects bodily movement. With regards to risk factors, students identified high blood pressure 182 (88.8%), followed by heart disease 175 (85.4%), advanced age 164 (80%), previous Stroke history 158(77.1%), and lack of physical activity 156 (76.1%). Difficulty in speaking or slurred speech 164 (80%), dizziness, and loss of balance 163 (79.5%) were identified as the warning signs of stroke. In this study, 41.3 % of the pharmacy students reported a good level of knowledge than nursing and EMS students. However, 32.2% (N = 66) of the healthcare undergraduates reported good knowledge. The knowledge score was significantly associated with the year of study, and educational degree (p = 0.0001). Furthermore, there were no differences between parents working in healthcare settings (p = 0.99).

Conclusion

In conclusion, the knowledge of stroke among healthcare students at King Saud University varied. The reported knowledge gap mostly relates to stroke risk factors and warning signs. Therefore, increasing public awareness of potential risk factors and stroke warning signs needs to receive more attention.

Evaluation of Young Adults' Physical Activity Status and Perceived Barriers in the Riyadh Region of Saudi Arabia

Background

Physical activity (PA) is any prolonged movement produced by muscular tissues that cause the muscles to exert force. Despite its beneficial effect, it is frequently neglected by individuals. The present study aimed to determine the PA among young adults living in Saudi Arabia.

Methods

This cross-sectional study was conducted among Saudi adults living in the Riyadh region of Saudi Arabia from June to August 2022 through a self-administered online survey. Global Physical Activity Questionnaire was used to assess the PA among participants. The data were analyzed using statistical software SPSS v. 26.0 (SPSS Inc., Chicago, IL, USA).

Results

Among the surveyed adult males were the predominant 67.8% (n= 240). Most of them were young, aged between 24 to 34 years 62.4% (n=221), and 37.6% (n=133) of them were between 35 and 44 years old. The current findings reported that 63% (n=223) of the adults had PA on weekly basis. Walking 45.2% (n=160) followed by bodybuilding 12.7% (n=45) was the most common type of PA identified among adults. The barriers identified for not practicing PA were lack of time 46.9% (n=166). With regard to a sedentary lifestyle, it was reported that 9.55 (SD= 4.887) hours per day are spent sedentary or in a constant sitting. The adults gender (p=0.046) employment (p=0.0001) and educational status (p=0.0001) was significantly associated with the type of PA engaged. Although being a female were shown more sitting behavior than males (p<0.047), similarly the nationality of the adults (6.67; SD=1.649) (p <0.001), education (p=0.028) and monthly household income (p =0.024) were significantly associated with the overall mean sitting behavior.

Conclusion

The findings of this study confirmed that Saudi adults yet posing highly sedentary behavior and physical inactivity, despite knowing the harmful outcomes of inactivity. Thus educating individuals about the importance of PA is warranted.

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.

Development and validation of a LC-PDA method for methylphenidate analysis in sewage

Methylphenidate (MPH) is an important emerging pollutant found in effluents and wastewater. Thus, we aimed to develop and validate a method for detection and quantitation of MPH residues in sewage through high performance liquid chromatography coupled with photodiode array detector (LC-PDA). Here we describe a selective, accurate, precise, and valid method for determination of MPH in sewage with a total running time of 10 min, with limits of detection and quantification of 0.27 and 0.92 µg/mL, respectively. MPH retention peak was observed at 5 min. The method was applied to MPH analysis in a sewage sample pretreated with solid phase extraction, obtaining a result of 2.8 µg/L of MPH. Thus, the developed method can be considered feasible to be applied to MPH residual contamination analysis in sewage using a widely available apparatus.

Knowledge and practices concerning the storage and disposal of home medications among people in the eastern region of Saudi Arabia: A cross-sectional study

Background

Medications are widely used and stored in people’s homes throughout the year. Inappropriate storage of home medications is a worldwide problem and may affect the effectiveness and stability of medications, which impacts the activity and capability of these medications to treat diseases. This study aimed to assess the awareness of the public in the eastern region of Saudi Arabia concerning the appropriate storage of used medications and the proper disposal of unwanted medications.

Method

A cross-sectional survey was conducted in the eastern region of Saudi Arabia between February and June 2018. The study questionnaire tool was constructed based on several previous studies regarding medication storage, recycling, and the correct and safe disposal of expired, unwanted, or unused medication.

Results

A total of 820 responses was collected. The results showed that 91.0% of the respondents keep their medications in the original container, and only 4.5% of them write the expiry date on the new containers. While 47.1% of the respondents read the storage instructions written in the medication leaflet, only 16.2% of the respondents ask the pharmacist about the storage instructions. A majority of the respondents (84.4%) check the expiry date of medications before use, and 70.1% of them periodically check the expiry date of stored medications. Age, gender, and education level were important factors that affected medication storage practices.

Conclusion

This work underpinned the lack of awareness among the public regarding the appropriate way to store home medications and the proper way to dispose of unwanted and expired medications.

The use of cleaning products and its relationship with the increasing health risks during the COVID-19 pandemic

OBJECTIVE

The present study aimed to determine the factors affecting the use of cleaning products at the home environment and the frequency of problems during the coronavirus disease-19 (COVID-19) pandemic.

MATERIALS AND METHODS

This cross-sectional research was performed online between 30 August 2020 and 15 September 2020. The population of the study consisted of adults aged between 18 and 80 years, affected by the COVID-19 pandemic. Data collection forms (introductory information and risk perception form and cleaning products usage characteristics form) were shared through Web2 tools. The questionnaire study was completed with 674 participants between the ages of 18 and 80 years in Turkey. Descriptive statistics and classification tree were used in the analysis of the data. Statistical significance was accepted as P ≤ .01 in all analyses.

RESULTS

During the pandemic period compared with the pre-pandemic period, it was observed that the frequency of cleaning (69.3%) and the amount of cleaning product usage (74.2%) increased significantly and the frequency of problems related to the use of cleaning products was found as 46.9%. The most commonly reported problems were skin disturbances (68%) and shortness of breath (23%). It was determined that the history of contact with the COVID-19 patient, the perceived risk of COVID-19 infection and risky cleaning behaviour were predictive in determining the risk of experiencing problems related to cleaning products. The amount of bleach consumed per month among who did experience problems was higher than those who did not experience problems and was associated with the perceived risk of COVID-19 infection.

CONCLUSION

In the COVID-19 pandemic, human beings have been found to increase the frequency of cleaning and using cleaning products. In order to reduce the negative effects of chemicals used for cleaning on human and environmental health, the trainings to be given by the teams providing primary healthcare services can be effective as well as general education activities for community groups.

The Impact of Consequences Awareness of Public Environment on Medicine Return Behavior: A Moderated Chain Mediation Model

With global aging trends and prosperity in the medicine market, the number of unused or expired household unused or expired medicines is increasing. Medicines which are discarded improperly result in serious pollution. From the perspective of behavioral science, the main contribution of this paper is the construction of a chain mediation model to analyze the influence mechanism between consequences awareness of the public environment and proper return behavior of unused or expired medicines. The model explores the moderating effect of personal health awareness with through observation of to the mediating effect of personal norms and return intention. Using a sample size of 366 residents from China, the proposed hypotheses are empirically tested. The results show: firstly, the direct effect of residents’ consequences awareness of public environmental awareness on the proper medicine return behavior is not significant; secondly, return intention plays a mediating role in the positive effect of consequences awareness of the public environment on proper return behavior; thirdly, personal norms and return intention play a chain mediating role in the positive impact of consequences awareness of the public environment on proper return behavior; and lastly, personal health awareness moderates the chain mediation path by strengthening the positive effect of return intention on proper return behavior.

Disposal Practices of Unused and Leftover Medicines in the Households of Dhaka Metropolis

Background: This fact-finding study aimed to attain an overall idea and knowledge about medicine disposal practices in Dhaka Metropolitan households. Methods: This mixed study (both quantitative and qualitative) was orchestrated to inspect the household leftover medicine disposal pattern's governing status. A cross-sectional survey was conducted following a structured questionnaire and key informant interview with a household person and in-depth interviews with the top pharmaceutical and government officials. Results: Findings disclose that, for most of the key informants, the terms "drug disposal" and "drug pollution" were unknown; more precisely, 67% and 74% of key informants even did not hear these two terms. Almost all (87%) households faced undesired incidents due to the insecure storage of medicines. People disposed of excess and expired medication in regular dustbins (47%), threw out of the window (19%), flushed within commode (4%), burnt in fire (2%), and reused (4%). A good percentage of people (21%) returned unexpired drugs to the pharmacy and bought other medicines on a need basis. A total of 72% wanted a medicine take-back program, and 100% agreed on mass education on this issue. Officials of pharmaceuticals conferred mixed opinion: top-ranked pharmaceuticals will adopt leftover medicine disposal practices; middle and low-ranked pharmaceutical companies are reluctant, merely denied mentioning the less important issue. Conclusions: The absence of mass awareness and standard laws and policies may explain these existing aberrant practices.

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.
