Abstract
Objectives Private pharmacies are widely established in most low/middle-income countries (LMICs) including Nepal, and are often considered as a patient’s first point of contact for seeking healthcare. The aim of this study was to investigate the pattern of antibiotic dispensing in private pharmacies through exit interviews with patients to review their medication information.
Design and setting Cross-sectional study. Data collection was carried out in 60 days at 33 randomly selected private pharmacies in the Rupandehi district of Nepal.
Participants Patients attending private pharmacies (n=1537).
Main outcome measure The pattern of antibiotic prescribing and dispensing was investigated using WHO’s core prescribing indicator, ‘the percentage of patients prescribed an antibiotic’. Frequency distributions were presented based on patients’ characteristics, sources of antibiotic, registration status of pharmacies and education of the pharmacist or drug retailer, and disease or condition. χ2 tests and regression analysis were applied to explore factors associated with the pattern of antibiotic dispensing.
Results Of patients attending private pharmacies, the proportion receiving at least one antibiotic (38.4%) was above the WHO recommended value (20.0%–26.8%). The most commonly dispensed antibiotics were cefixime (16.9%) and the third-generation cephalosporins (38.0%) class. High dispensing rates of antibiotics for selected conditions (eg, respiratory infections, diarrhoeal cases) appeared contrary to international recommendations. The percentage of antibiotic dispensed was highest for patients who obtained their medicines from unlicensed pharmacies (59.1%). Young people were more likely to receive antibiotics than other age groups.
Conclusions The antibiotic dispensing pattern from private pharmacies in Nepal was high compared with WHO guidelines, suggesting initiatives to reduce inappropriate use of antibiotics should be implemented. The findings of this study may be generalisable to other LMICs in order to assist in developing policies and guidelines to promote more appropriate dispensing and prescribing practices of antibiotics and limit the spread of antibiotic resistance.

Strengths and limitations of this study
This is the first study to investigate the pattern of antibiotic dispensing in private pharmacies in Nepal.
Data on dispensing of medications including antibiotics were sourced directly from patients and validated from the dispensed medicines.
Data were collected from a wide range of private pharmacies including high-end outlets staffed by pharmacists and small outlets staffed by drug retailers without formal health qualifications.
Exit interviews were based on convenience sampling with interviews conducted between 09:00 and 17:00, thus may not be representative of all patients attending private pharmacies.
Description of diagnoses or conditions by patients were symptom-based rather than disease-specific, which made it difficult to assess appropriate use of antibiotics and whether antibiotic dispensing and prescribing followed the standard guidelines.
Introduction
The role of the private sector in healthcare in low/middle-income countries (LMICs) has often been neglected by governments and international public health communities.1 However, private pharmacies are widely established in most LMICs, and usually considered as a patient’s first point of contact for healthcare and the preferred channel through which to get health services and medicines.2 These pharmacies range from high-end outlets to small, rural, road side stalls and can be staffed by fully trained pharmacists or a drug retailer or seller without formal health qualifications. Because of ease of access, more flexible opening hours, availability of cheaper medicines and credit3 and personal intimacy,4 consumers often tend to use private rather than public facilities.5 Further, many patients have neither the time nor money to consult a physician6 preferring over-the-counter medicines and healthcare advice. About three in four antibiotic requests and three in five consultations in community pharmacies around the world result in the sale of antibiotics without a prescription.7
Non-prescription use of antibiotics is associated with the risk of inappropriate drug use, defined as patients not receiving the appropriate medicines in doses that meet their individual requirements, for an adequate duration, and at the lowest cost.8 Inappropriate use of medicines is a serious global problem occurring in both developed and developing countries,9 with the WHO estimating more than half of all medicines are inappropriately prescribed, dispensed or sold.8 This overuse and misuse of antibiotics is one of the main causes of antibiotics becoming ineffective,10 thus posing problems relating to treatment failure and other costs to the individual and society.11–13
In Nepal, dispensing of medicines is undertaken by pharmacists and drug retailers or sellers and many dispensers have admitted treating patients too by also prescribing medicines.14 Pharmacists have 3–5 years of pharmacy education14; however, drug retailers and sellers include individuals who are only associated with private pharmacies, do not necessarily have formal education in dispensing medicines, but can undertake training and obtain a licence to own and operate a pharmacy from the Department of Drug Administration (DDA), the government body dealing with medicines and their related affairs.15 16 Practising healthcare without a license is illegal in Nepal17; however, many unlicensed pharmacies are also operating in remote areas of Nepal.18 Little is known about the antibiotic dispensing practices from licensed or unlicensed private pharmacies in Nepal. Previous studies conducted in Nepal that have examined antibiotic dispensing practices from private pharmacies have collected data directly from pharmacists or drug sellers themselves,18 19 which may result in inaccurate reporting of dispensing practices. This study has investigated patterns of antibiotic dispensing through exit interviews with patients by reviewing their medication information, thus ensuring collection of reliable information. The findings of this study reveal issues about inappropriate use of antibiotics and can be used as a baseline against which to evaluate initiatives to improve antibiotic dispensing and prescribing practices in the private pharmacy sector in Nepal.
Methods
The study was a cross-sectional study conducted in the Rupandehi district of Nepal. This district was selected because it has an almost equal mix of urban and rural residents20 21 and a well-represented population of different castes and ethnicities with >63 castes/ethnicities residing in the district22 out of 126 castes/ethnicities in the country.23 Within the district, there is varying access to transport, with good transport only available in urban areas, which is similar to other districts of Nepal.
Private pharmacies were selected based on WHO guidelines.24 25 Before deciding on the private pharmacies, six survey areas were selected from the seven electoral areas in the district. The district in which the major hospital is located was selected as one survey area and an area with the lowest socioeconomic status as another survey area. An additional four survey areas were randomly selected. One public health facility was selected from each survey area using a list obtained from available records of the District Public Health Office. Altogether, six public health facilities were selected, two each from hospitals, primary healthcare centres and health posts, with the major hospital included as one of the hospitals (as per WHO guidelines). These health facilities were used as the basis for selecting the private pharmacies.
Private pharmacies to include in the study were selected from a list made available by the Nepal Chemists and Druggists Association (NCDA), Lumbini, Nepal. Separate pharmacies and pharmacies attached to private hospitals were included to represent both types. The NCDA list was verified after visiting each selected survey area and updated by deleting any duplicates in the list of pharmacies and adding any missing from the records. In total, 441 private pharmacies were in the NCDA list. Among them, 49 did not exist in the field while 31 were missing on the list. After adjusting the list for these pharmacies, 423 private pharmacies were included in the final list.
As outlined in the WHO guidelines, within each survey area, pharmacies on the final list were grouped according to whether they were located within or beyond 5 km from each selected public health facility. Within each group in every survey area, pharmacies were assigned a number and then selected for inclusion in the study using a random number generator, with three private facilities selected from the within the 5 km group and two selected from the >5 km group. Three private pharmacies were added to the original sample due to refusal of the initially selected pharmacies to allow data collection on the second day. Each pharmacy was surveyed for 2 days, other than the three that refused data to be collected on the second day and the three replacement pharmacies, which were surveyed for 1 day. Thus, data collection covered 60 days with 33 private pharmacies (2 days per pharmacy for 27 pharmacies and 1 day per pharmacy for 6 pharmacies).
Data collection
Private pharmacies in Nepal do not follow the practice of keeping patients’ records, so exit interviews were conducted with patients who had attended the selected pharmacies. Interviews were conducted from July 2017 to December 2017 from 09:00 to 17:00. The days allocated for data collection were based on the advice of pharmacists to obtain as representative a sample of days as possible. Patients were invited to participate based on convenience sampling, with as many patients as possible who attended the selected pharmacies approached to participate. In total, 1554 patients were approached, with 15 (1%) patients refusing to participate and 1537 patients included in the study. Individuals obtaining medicines on behalf of another person were excluded from the exit interviews as they may not have been able to provide the relevant details about the patient or their condition. In contrast, parents have these details for their children so children attending the pharmacies with their parents were included in the survey.
Data were collected using the Qualtrics Offline Surveys Application.26 Demographic characteristics of the patients for whom the medicines had been bought (age, sex), the disease or condition and sources of antibiotic27 (self-medicated, recommended and supplied by a pharmacist or drug retailer without a prescription, prescribed by a doctor and dispensed by a pharmacist or drug retailer, other) were collected. Photographs were taken of the medicines, with no patient identifiers included, and attached to the application. The maximum time taken for the exit interview was 3 min. Prior to the interview, all consumers were informed of the nature of the study and written consent was sought to interviews being conducted. Consent for patients younger than 18 years was sought from the accompanying parent or caretaker.
The principal researcher coordinated data collection and approached respective authorities and health facilities to obtain approval to collect the data, and four Nepali research assistants were engaged in data collection. A training session for research assistants was held prior to embarking on data collection and focused on the aim of the study, the importance of ensuring quality in the data collection and ethical considerations. The research assistants were regularly monitored by the principal researcher to ensure the quality of the data through observation at the study sites and cross-checking of the entered records in the Qualtrics Application.
Data analysis
The data were imported from the Qualtrics Application to a MS-Excel spreadsheet for cleaning. The cleaned data were transferred to the SPSS statistical software (IBM Corp. Released 2017. IBM SPSS Statistics for Windows V.25.0). Diseases or conditions collected from the interviews were generally described based on symptoms, thus similar symptoms were grouped together. For some analyses, the most commonly occurring groups (such as fever, respiratory symptoms and skin conditions) were separately analysed, with remaining groups combined into those likely to have an infectious cause (‘other: infectious’), and those not likely to have an infectious cause (‘other: non-infectious’). Antibiotics were also grouped into classes for analysis.28 A core prescribing indicator, ‘the percentage of patients prescribed an antibiotic’ was computed in line with the WHO’s standard values.29 Descriptive analysis was conducted to show commonly dispensed antibiotics, sources of antibiotic, registration status of pharmacies and education of the pharmacist or drug retailer, and disease or condition. χ2 tests were performed to examine the association between antibiotic dispensing and explanatory variables including sex, age group of patient, sources of antibiotic and registration status of pharmacies and education status of the pharmacist or drug retailer. Logistic regression was also used to examine factors associated with antibiotic dispensing. An interaction term of sources of antibiotic with registration status and education was also examined. The significance level (α) was set at 0.05 for all statistical tests.
Patient and public involvement
No patients or public were involved in the design and conduct of the study.
Results
Characteristics of patients and prescription information
The sample comprised a similar number of male and female respondents, with all age groups relatively well represented (table 1). Just over half of patients (55.2%) had a prescription from a doctor or health worker, with about one-quarter not having a prescription but purchasing a medicine recommended and supplied by the pharmacist. Almost equal numbers of patients received their medicine from a pharmacist who had a diploma or bachelor’s degree in pharmacy (49.6%) and drug retailers who had completed training from DDA (46.1%). The most commonly occurring diseases or conditions were fevers (18.1%), coughs (5.3%) and respiratory infection (4.9%). At least one antibiotic was dispensed in 947 (38.4%) patient encounters.
Commonly dispensed antibiotics
Among antibiotics, the most commonly dispensed were cefixime (16.9%), amoxicillin (12.2%), cefpodoxime (10.3%), ampicillin + cloxacillin (8.7%) and ciprofloxacin (8.7%). Cephalosporins (38.0%) were the most commonly dispensed class of antibiotics, followed by penicillins (29.3%), quinolones (13.7%) and marcolides (8.1%) (table 2).
The percentage of antibiotics dispensed was highest for those patients for whom the medicine had been prescribed by a doctor or health worker (58%). It was also highest for patients who obtained their medicines from an unlicensed pharmacy (59.1%). For several conditions, antibiotics were the most commonly dispensed medicine, including for respiratory infection (93.3%), diarrhoea and dysentery (91.3%), skin infection (87.1%), fever (70.5%) and urinary tract infection (57.9%).
The class of antibiotics dispensed was relatively similar by sources of antibiotic and registration status and education. Third-generation cephalosporins were the most common class of antibiotics recommended and supplied by a pharmacist or drug retailer without a prescription (40.7%) and prescribed by a doctor or health worker (38.1%), with antiprotozoals the most common among patients who self-medicated (38.5%). Cephalosporins were also most commonly dispensed by both drug retailers who had training from DDA (41.3%) and those with a diploma or bachelors in pharmacy (36.1%). The highest dispensing rate of cephalosporins was for the treatment of fever (69.5%), whereas penicillins were common for respiratory infection (60.8%), injuries (78.8%) and skin infection (67.2%) (table 3).
Factors associated with antibiotic dispensing
Across all diseases and conditions, antibiotic dispensing was significantly associated with age group, sources of antibiotic, and registration status and education of pharmacists (table 4). Patients <15 years were more likely than all other age groups to receive antibiotics (p≤0.001). Those patients who attended a pharmacy without a prescription from a doctor or health worker were less likely to receive antibiotics than patients with a prescription (p≤0.001). In addition, patients were less likely to receive antibiotics from pharmacists who had a diploma or bachelors in pharmacy (p=0.001) compared with unlicensed drug retailers or licensed retailers with training from DDA only. The interaction term shows that patients who presented with no prescription were more likely to receive an antibiotic if they presented with no prescription to a pharmacy attended by a trained pharmacist.
Discussion
In most developing countries, private pharmacies or drug stores are the first point of contact for people seeking healthcare.2 Antibiotics (and other prescription medicines) are readily available with or without prescription, and self-medication by patients is common. Non-prescription use of antibiotics is associated with a risk of inappropriate use due both to failure in dispensing in accordance with clinical guidelines and patients not using the drug appropriately.30 It is also one of the drivers of the emergence of antimicrobial resistance.31
Findings of this study show the overuse of antibiotics dispensed from private pharmacies, with the percentage of patients dispensed an antibiotic (38%) being considerably higher than the level recommended by the WHO (20%–26.8%).29 This finding of overuse is consistent with studies conducted in private facilities in other LMICs including 43% in both India32 and Uganda33 and 53% in Bangladesh.34
Unlicensed pharmacies, especially outside of cities, often exist in LMICs.35 These pharmacies sell medicines informally and are not legally recognised by the health system of the countries in which they operate.36 While, practicing healthcare without a license is illegal in Nepal,17 weak regulatory oversight of the Nepalese health system encourages pharmacies to operate without licences. This study found the level of dispensing of antibiotics was higher by unlicensed drug retailers and drug retailers with limited training. Interestingly, the interaction term in the multivariable model suggests that, while this is the case, if patients presented to a pharmacy with a trained pharmacist without a prescription, they were more likely to receive antibiotics. It has been suggested that drug retailers may approach dispensing of medicines as any other sales job, not wanting a customer to leave without making a purchase.35 More generally, inappropriate dispensing of antibiotics may occur due to the business motive of private pharmacies with profits from antibiotics contributing to total profit.37
Third-generation cephalosporins were the most common antibiotic type recommended and dispensed with or without prescription. The finding is consistent with the studies conducted in India showing cephalosporins were the most commonly supplied class of antibiotic in private pharmacies or clinics32 and often used by urban private health facilities.38 Guidelines often advise that cephalosporins should be avoided as a first-line treatment when a narrower spectrum antibiotic would be effective because they increase the risk of Clostridium difficile, methicillin-resistant Staphylococcus aureus and other resistant infections.39 40 Noticeably, third-generation cephalosporins were dispensed to patients with minor symptoms, such as fever, which is self-limiting in most cases and could be a common symptom of several infections. The popularity of third-generation cephalosporins lies in their lesser allergenic and toxicity risks as well as having a broad spectrum of activity.39 In Nepal, treatment guidelines do not recommend cephalosporins as a first-line treatment for several infections such as respiratory tract infections, enteric fever, pneumonia and urinary tract infections.41
Overprescribing and overuse of antibiotics in the treatment of respiratory infections and diarrhoea is a worldwide problem, potentially leading to widespread antimicrobial resistance.42 Contrary to international recommendations, this study found high prescribing rates of antibiotics for both conditions, suggesting possible overprescribing. The WHO guidelines recommend oral rehydration solution with other supplements for non-bloody diarrhoea43 and home care without antibiotics for children with respiratory symptoms.44
Across all conditions collectively, antibiotics were more likely to be dispensed to younger age groups especially <15 years of age compared with older groups. Respiratory diseases and diarrhoea impose a considerable health burden especially to children in LMICs,45 46 and may lead to antibiotics being used more widely for the treatment of these diseases.47 48 Higher self-medication practices among younger age groups could also be a factor contributing to higher antibiotic dispensing for younger age groups, with a study in Albania finding an association between self-medication and a higher use of antibiotics among younger age groups.49 Additionally, increased education has been found to increase the risk of self-medication with antibiotics,50 and globally the literacy rates of young adults is higher than the elderly, with the differences even wider in developing countries.51
Policy implications
Levels of antibiotic prescribing above the WHO recommended rate suggests the need to implement measures to reduce potential inappropriate use in Nepal. Almost half of patients were dispensed antibiotics by drug retailers who, unlike pharmacists are professionally trained and do not have formal education in dispensing medicines. While this study did not examine their technical competencies, drug retailers should be encouraged to increase their skills through continued professional education.
In Nepal, prescribing is conducted by physicians and non-physicians such as auxiliary health workers and health assistants, who have 18 months to 3 years postsecondary training in diagnostics and therapeutics, and nurses.52 The physicians work at hospitals and non-physicians, who are referred to as health workers, mostly work in public health facilities at the community level and have their own private pharmacies. Health workers are less qualified than physicians but are authorised to prescribe medicines as outlined in the antibiotic treatment guidelines.41 However, such guidelines are barely in practice or monitored.53 WHO’s guideline of good pharmacy practices confines the role of pharmacists to dispensing only.54 A general lack of enforcement of the legislation covering registration of pharmacies and the distribution of antibiotics facilitates the inappropriate use of antibiotics in Nepal. Stronger enforcement mechanisms of pharmacy registration and restricting pharmacists and drug retailers supplying antibiotics without prescription should be established.
Private pharmacies are widely established in most LMICs including Nepal. They are usually considered as a patient’s first point of contact and preferred channel to receive health services2 particularly given issues relating to the unavailability and inaccessibility of quality of care from public health facilities.55 Private pharmacists and community members are often known to each other and pharmacists can be under pressure to supply antibiotics.56 Pharmacists and drug retailers generally do not charge consultation fees and profits from selling drugs is a main source of their income,57 which could encourage the selling of antibiotics since it is one of the more profitable medicines.37 A targeted intervention to provide education and training relating to antimicrobial resistance and supplying antibiotics only with prescriptions will lead to greater consideration of antibiotic dispensing practices based on the standards of good pharmacy practices, thus contributing to a reduction in the risk of development of antibiotic resistance bacteria.
Additionally, the relatively high prescribing rate of third-generation cephalosporins in private health facilities in Nepal is of concern, given that these classes are considered second-line antibiotics in most guidelines. When antibiotic therapy is necessary, the use of narrow-spectrum antibiotics should be used as first-line treatment whenever possible58 to prevent drug-resistant bacteria developing. Educational interventions to reduce inappropriate dispensing or prescribing of antibiotics in unwarranted situations should include guidance on the proper selection of antibiotics.
Strengths and limitations
Limited evidence is available in regard to the pattern of antibiotic dispensing in LMICs. This study has provided an evidence base about the current pattern of antibiotic dispensing from private pharmacies in Nepal, with data on dispensing of medications including antibiotics sourced directly from patients and validated from the dispensed medicines. Data on dispensed medicines were collected from a wide range of private pharmacies including high-end outlets staffed by pharmacists and small outlets staffed by someone without formal health qualifications. The information on dispensed medicines provides a useful baseline against which to measure the effectiveness of future policies and programmes to reduce the level of inappropriate dispensing of antibiotics. The findings of the study also reinforce calls to build a strong regulatory environment in advancing prudent antibiotic use. The findings may also be applicable to other LMICs, where the health system is similar to Nepal.
However, the study has several limitations. The study covered about 8% (33/423) of private pharmacies in the Rupandehi district. While the selection process followed WHO guidelines, these guidelines do not account for the number of facilities in the district, thus the sample of pharmacies selected may not be representative. Interviews were conducted between 09:00 and 17:00 at the selected pharmacies, which excludes patients attending the pharmacies at other times, and exit interviews were based on convenience sampling. Diagnoses or conditions of patients were non-specific and recorded based on the understanding of the patients. Description of diagnoses or conditions were more symptom-based and were grouped into broad categories together with related conditions. Having such broad categories made it difficult to assess appropriate use of antibiotics. It also prevented any investigation of whether antibiotic dispensing and prescribing followed the standard guidelines. Another limitation is that the Rupandehi district lies in a low-land region of Nepal, which has a greater availability of health services than in hill and high-hill regions. Results of the study are thus more generalisable to districts falling in low-land regions than hill and high-hill regions, a factor which needs to be considered in using findings from the study in developing and implementing policy to improve pharmacy practice in Nepal and similar countries.
Conclusion
This study documents antibiotic dispensing practices in private pharmacies in Nepal that were high compared with WHO guidelines. The overuse of antibiotics has been associated with a higher prevalence of antimicrobial resistance. Given global concerns about antimicrobial resistance, evidence relating to overuse and misuse in Nepal provides a rationale to consider introducing initiatives to reduce inappropriate use of antibiotics. Additionally, this evidence may be more widely generalisable to other countries with similar health system financing arrangements.
