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.

Prevalence of Home Storage of Medicines and Associated Factors in Iraq

BACKGROUND: In most families around the world, medicines can be used to treat chronic or acute diseases. Simple access to medicines at home has led to high drug consumption rates for self-limiting diseases. Incorrect use of these home-stocked medications may also contribute to severe health risks, increase pathogens’ tolerance, prolonged distress, increased adversity, medication reactions, and delays in seeking adequate care if misdiagnosis occurs. Nothing is known about how Iraqi people store their medicines at home. AIM: The purpose of this study is to obtain data on the prevalence and related factors of drug storage in Diyala Governorate, Iraq. METHODS: A community-based cross-sectional descriptive study was conducted in Diyala Province, Iraq in July 2019. A total of 200 students participated in this study. A pre-tested standardized questionnaire was used to collect data and the analysis was performed using descriptive statistical methods. All the participants (100%) enrolled reported to keep medicines at their homes. RESULTS: The average number of drug users per household is 12.32%. Refrigerators are the main storage location (65%), followed by kitchen counters (33%). The majority of stored drugs were prescribed by physicians (78.5%) and the leading source of those drugs is a private pharmacy (55.71%). The most popular medicinal products stored were analgesics (23.1%), followed by antimicrobials (antibiotics, antibacterial, and antifungal) (19.44%). Among all medicines, currently used drugs accounted for 43.34%, remaining drugs accounted for 29.78%, and reserved drugs accounted for 26.87% for future use. The most common dosage forms of these drugs are tablets (21.16%) and capsules (20.95%). Most participants (82.5%) revealed that they always check the expiration date before use, and (37%) admitted to sharing drugs with others. CONCLUSION: The prevalence of drug storage in households in the Diyala Governorate of Iraq is high because all participants keep drugs at home. Regardless of the method used, these drugs should be retained, and proper storage procedures and conditions are rarely observed.

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.
