Abstract
OBJECTIVE: To explore the knowledge, attitude, perception and practice towards antimicrobial use in upper respiratory tract infections in patients visiting healthcare settings in Qatar. DESIGN: Systematic review was performed using a predetermined protocol and in accordance with standardized reporting guidelines. MEDLINE, PubMed, EMBASE, Global Health and PsycINFO were searched for relevant published studies using relevant MESH terms and keywords. SETTING: All healthcare settings in Qatar including both inpatient and ambulatory care. PARTICIPANTS: All published articles exploring the antimicrobial use in upper respiratory tract infections at any health setting in Qatar were considered for inclusion in the study. No age, gender or population were excluded. MAIN OUTCOME MEASURES: The outcome of interest was antimicrobial use in upper respiratory tract infections in Qatar. We included all related studies to explore the knowledge, attitude, perception and practice for patients visiting all health care settings. RESULTS: Three articles were included, one in a primary care setting, one in a secondary care setting and one in the private sector. Overprescribing was noted in all settings. Our findings demonstrate low expectations to receive antibiotics, among the Qatari population, in primary care (28.1%). In fact, the majority of patients would be satisfied with reassurance rather than receiving antimicrobials. Many patients were satisfied with explanation from physicians and counselling. Private sector registered high prevalence of antimicrobial misuse for respiratory tract infections in which 85% deemed inappropriate. This finding was also noted at a medical intensive care unit which showed high antimicrobial use (76%) and respiratory tract infections accounted for 57% of prescriptions. CONCLUSION: Studies are needed to determine factors and population-based rates of antimicrobial use in all healthcare settings. There is also a need for interventional programs for both physicians and public on appropriate use of antimicrobials to combat global antimicrobial resistance.

In the past decade, the worldwide consumption of antimicrobial drugs has increased
substantially. In many countries, antimicrobials are either legally available
without a prescription, or existing regulations are not uniformly enforced. Studies
indicate that in countries with little regulation, substantial misuse takes place.[1] A study reported that 77% of Greek pharmacists offered antibiotics without a
medical prescription. Antimicrobials were most frequently offered for treatment of
patients with symptoms that were suggestive of a common cold.[2] Data from a variety of countries suggest that self-medication is common and
frequently inappropriate; antimicrobials are often purchased without proper
indication, in insufficient quantities, or when contraindicated.[3] Physician visits for respiratory tract infection commonly result in an
antimicrobial prescription,[4,5]
despite the fact that most upper respiratory tract infections are viral in nature.
In these cases, antimicrobials provide no benefit; thus, guidelines limit their
recommended use to certain situations where the aetiology is likely bacterial.[6]According to our knowledge, this is the first known systematic review study to be
conducted about this topic in Qatar. These findings would establish a baseline for
knowledge, attitude and perception towards antimicrobials use for respiratory tract
infection. This will assist stakeholders in the assessment of the adequacy of the
current strategies on antibiotics. In addition, this would help in implementing
multidimensional interventions to combat antimicrobial overprescribing.Acute respiratory tract infections (ARTIs) account for a large proportion of
community antimicrobial use in many countries.[7] Worldwide, antimicrobial overprescribing is a major health problem which
contributes to the rise of antimicrobial-resistant bacteria.[8] In places with greater prescribing of broad-spectrum antibiotics,
specifically extended-spectrum cephalosporins and macrolides, rates of
multidrug-resistant pneumococcal disease are higher.[9] Differences in prescribed antimicrobials among the countries can partly be
explained by availability of antimicrobials and differences in guidelines. Quality
indicators (QIs) have already been developed within the context of the European
Surveillance of Antimicrobial Consumption (ESAC) project[10] based on outpatient use data. Antimicrobials are frequently prescribed for
the management of upper respiratory tract infections, even though most of these
infections are viral in origin.[4] A recent report has documented that most respiratory tract infections are
caused by viruses, and the probability of their resolution without the
administration of antimicrobials is high.[11]The relationship between antimicrobial use and resistance development is strong and
supported by several studies.[12,13] Countries with the highest per
capita antimicrobials consumption have the highest prevalence of resistant
pathogens. Overuse of antimicrobials can lead to resistance, increased cost and
increased incidence of adverse effects, including anaphylaxis.[14] Outpatient antimicrobial use represents around 90% of total antimicrobial
use, with more than half of these prescriptions being either unnecessary or inappropriate.[15] Between 20 and 50% of all antimicrobial use is inappropriate.[16] In the USA, antibiotics are prescribed for more than 100 million adult
ambulatory care visits annually, and 41% of these prescriptions are for respiratory conditions.[17] At least two million antibiotic-resistant illnesses and 23,000 deaths occur
each year, at a cost to the U.S. economy of at least $30 billion.[18] Ambulatory antimicrobial consumption accounted for between 85% and 95% of
total antimicrobial use in 2012 in the European Union, according to countries
contributing data on both ambulatory and intra-hospital antibiotic use to the
European Centre for Disease Prevention and Control (ECDC).[19]The use of over the counter antimicrobials is common in many countries, and
non-prescription use accounts for 19–100% of antimicrobial use outside Northern
Europe and North America. Even when prescriptions are needed to obtain
antimicrobials, physicians might not adequately screen for appropriate use.[20] Similarly, in the six countries of the Gulf Cooperation Council (GCC), two
studies[21,22] reported the emergence of antimicrobials resistance which was
mainly attributed to the inappropriate prescribing of antimicrobials and overuse of
antimicrobials including self-medication. Other factors included the lack of
policies for restricting and auditing antimicrobial prescriptions in many GCC
countries.The inappropriate use of antimicrobials may arise from a complex interaction between
factors such as prescribers’ knowledge and experiences, diagnostic uncertainty,
perceptions of patients in relation to the patient–prescriber interaction, and
insufficient patient education by physicians. Additional factors that can influence
prescribing include patients’ knowledge, beliefs and attitudes towards antimicrobial
use, self-medication, patients’ expectations, and patients’ experience with
antimicrobials.[23-25] Knowledge of
and attitudes towards antimicrobial use have been shown to be a good predictor of
the appropriate use of antimicrobials by patients.[26,27] The interventions that are
most successful at reducing inappropriate antimicrobial prescribing tend to be
multifaceted and combine physician, patient and public education.[28]Antimicrobial misuse is a global concern and stakeholders in Qatar have made advances
to combat antimicrobial resistance. A National Action Plan was developed to support
a collaborative and integrated effort to change practices which lead to reduce the
inappropriate antimicrobial usage that causes resistance. The National Action Plan
is expected to improve antimicrobial stewardship in all healthcare settings. This
stewardship aims to improve practice through various interventional strategies which
include increasing awareness, effective communication, strengthening knowledge, etc.
Data regarding antimicrobial use are deficient and a few studies have been conducted
to explore people’s knowledge about antimicrobial use for respiratory tract
infection in the State of Qatar. As such, the aim of this research is to generate an
evidence base of the knowledge, attitude and practice regarding antimicrobial use in
upper respiratory tract infections among patients visiting healthcare settings in
Qatar to support the evidence-informed policy decisions to curb anti-microbial
resistance (AMR).
Methods
This systematic review was performed using a predetermined protocol and in accordance
with standardised reporting guidelines. A search of published literature
investigating knowledge, attitude, perception and practice regarding antimicrobial
use in upper respiratory tract infections attending healthcare settings in Qatar and
including both inpatient and ambulatory care which is mostly utilised was conducted.
Databases such as MEDLINE, PubMed, EMBASE, Global Health and PsycINFO were searched
for relevant published studies using the following MESH terms and keywords:
antibiotic use, antimicrobial resistance, Qatar. The search was performed on 31 May
2017, and was not restricted by language or date. In addition, reference lists of
prior review papers and all identified research articles were hand searched.
Study selection
Articles were evaluated for eligibility in a two-stage procedure. In stage one,
titles and abstracts were identified and reviewed. In stage two, a full review
was performed to identify articles that met the eligibility and inclusion
criteria. Two reviewers (FS and SH) independently reviewed each selected
article.
Inclusion criteria
All published articles exploring the antimicrobial use in upper respiratory tract
infections at any health setting in Qatar were considered for inclusion in the
study. No specific age, gender or population were excluded.
Exclusion criteria
Studies that did not measure knowledge, attitude, perception and practice
regarding antimicrobial use or were published in abstract only form, or not
original, were excluded.
Data extraction
Two reviewers (FS and SH) independently extracted data from included studies.
Data were extracted for knowledge, attitude, perception and practice regarding
antimicrobial use. Data were arranged into categories that emerged from
extraction: patients’ expectations, knowledge, attitude, perception, practice
and prevalent use of antimicrobials.
Quality assessment
Included articles were assessed for quality using the Newcastle and Ottawa Scale tool.[29] The two reviewers (FS and SH) independently performed data abstraction
and quality appraisal. Abstractions and appraisals were compared for each study,
and any disagreements were resolved by discussion. Both reviewers extracted all
the data from each study.
Results
We identified 11 articles through database searches. Of these, we excluded two
duplicated papers. We assessed nine non-duplicated papers and excluded six on the
basis of title and abstract screening. Full text papers of the remaining three were
obtained and assessed. They met our eligibility criteria and were considered
relevant and determined to be of good quality; therefore, they were included in our
review (Figure 1).

Study selection: PRISMA chart.The three included studies were conducted in different settings, one was conducted in
a primary care setting, the second one was conducted in a secondary care setting and
the third study was conducted in the private sector.Said and co-workers[30] asked 1111 participants in a primary health setting about the most common
causes for URIs. About 40% of the participants answered ‘viruses’ as the most common
cause of upper respiratory tract infection, while 24.2% considered that both viruses
and bacteria were the most common cause. In a multinomial logistic regression in the
same study, younger participants were more likely to ‘know’ than older participants
(p < 0.0001). Also, 40.9% of the participants did not know
about the least common cause of upper respiratory tract infection, and about a fifth
of the participants thought bacteria was the least common cause.Moreover, 14.74% of the participants expecting antibiotics chose bacteria as the most
common cause of upper respiratory tract infection compared to 6.13% of those
participants who were not. On the other hand, a higher percentage (17.31%) of those
expecting antibiotic prescription identified viruses as the least common cause
compared to the participants who did not (11.14%).The study revealed that antibiotics were expected by 28.1% of the participants, and
64.9% did not expect any specific treatment. Also, 5.4% stated that they expected
treatment other than antibiotics. In addition, 70.9% of the participants consulted a
physician, 13.6% reported that they used antipyretics and fluids as a first course
of action, and 2.7% consulted a pharmacist when asked about their practices upon
acquiring upper respiratory tract infection. Older participants were more likely to
use antipyretics (p = 0.02) and males were less likely to use
antipyretics and fluids (p = 0.02), respectively.The study also showed that 49.6% of the participants were dissatisfied with the
physician not giving any treatment, and 31.6% of them would seek antibiotic
prescription. Older participants were significantly more likely to seek antibiotic
prescription if it was not provided by physician (β = 0.134,
p < 0.029). Also, 27.4% cited severity of symptoms, 19.4% cited
previous experience and 14.7% cited duration of their illness as factors leading
them to believe that antibiotic treatment is needed. A higher percentage of those
expecting antibiotic treatment cited a previous experience compared to those who are
not (21.79% and 18.40%), respectively.The majority of participants wanted information and discussion during counselling.
Around 98% of them preferred physician explanation about causes of URI before
recommending treatment. In addition, 97.3% of the participants reported that the
physician’s explanation and education would help them and 88.2% would feel more
comfortable regarding treatment if the physician discussed treatment options prior
to writing a prescription.A study conducted by Adeel et al.[31] between May 2014 and December 2015 for 75,733 claims for non-topical
antibiotics in the private sector showed that 45% of the antibiotics were deemed
inappropriate based on the accompanying diagnosis. The most common diagnosis
associated with inappropriate antibiotic prescription was acute upper respiratory
tract infections (28,898 claims; 85% of inappropriate prescription).The largest number of prescriptions was provided by general/family practice
physicians, accounting for 52.7% of the prescriptions (50% inappropriate), followed
by paediatrics (18.6% of prescriptions; 36% inappropriate) and internal medicine
(14.1% of prescriptions; 44% inappropriate). Although emergency medicine physicians
accounted for only 2% of the prescriptions, they registered the highest number of
inappropriate prescriptions (74%) with >1000 claims.Cephalosporins were the most common antibiotic classes prescribed (43% of claims; 44%
inappropriate), followed by penicillins (28% of claims; 44% inappropriate),
macrolides (19% of claims; 52% inappropriate), and fluoroquinolones (9% of claims;
40% inappropriate). Nearly 5% of antibiotics were prescribed in intravenous
formulations.Hanssens et al.[32] conducted a study among 71 eligible patients out of 159 admitted to the
medical intensive care unit. Seventy six per cent were treated for presumed or
proven infections and received antibiotics in which respiratory infections accounted
for 57%. A total of 159 antibiotics were administered to those patients during their
stay in the medical intensive care unit, with an average of almost three antibiotics
per patient. In these 54 patients, a total of 385 microbiology samples for culturing
were taken throughout the study period, corresponding with more than one sample per
patient per day. Twelve per cent of the samples were mainly from the respiratory
tract. However, no antibiotic was discontinued due to negative result. Ceftriaxone
was prescribed in 57% of patients as initial therapy. Further detail on the data
extracted from the study are found in Table 1.

Discussion
Knowledge regarding antimicrobial use in upper respiratory infections
A higher percentage of participants expecting to be prescribed an antimicrobial,
who thought the most common cause of respiratory tract infections is bacteria,
were evident in the Said and co-workers’s study. Yet, approximately half of the
participants in the study revealed no dissatisfaction if the physician did not
provide any prescription.[30] Doctors could help address perceptions that common symptoms do not
warrant antimicrobials, and that these could be due to viral infections. Also,
they could reassure concerned patients about their illness, where appropriate,
to ease unnecessary worries and thus avoid the demand for antimicrobials.Moreover, the study revealed that the majority of participants favoured
discussion with the physician about upper respiratory tract infection aetiology
and management.[30] Studies[32-35] reported that patients
were satisfied with proper examination and reassurance, regardless of whether an
antimicrobial was prescribed or not, and that they need to know that their
illnesses are not serious. In addition, previous findings identified that
physicians are the main source of information and it seems that spending more
time with patients may reduce the prescribing of antimicrobials.[36] This would result in a decrease in the number of future visits for
respiratory tract infections and workload on clinics.[37] Therefore, explaining that antimicrobial treatment would not modify
symptoms and is associated with side effects might be more useful in influencing
patients’ expectations and views regarding antimicrobials.
Socio-demographic factors and past experience pertaining
antimicrobials
Perception of the need for antimicrobials can be affected by different factors,
such as past experience and age. Said and co-workers reported that being older
and having past experience are factors affecting the perception of the need for antimicrobials.[30] This study seems to suggest that the more patients used antimicrobials in
the past, the more likely they were to desire antimicrobials when presenting for
care, and the more likely they were to actually receive antimicrobials again.
Prior experience may have verified to patients that antimicrobials work. Also,
the rate of self-medication in Qatar cannot be determined and is limited because
antibiotics cannot be dispensed without a prescription. However, findings from
other studies were contradictory as self-medication was common among those with
negative attitudes towards antimicrobial use, and is not associated with
knowledge in Kuwait,[38] unlike in the UK.[39] Physicians should be involved in public education campaigns, to
strengthen them, since it has been shown that effective doctor–patient
communication and patient empowerment reduced inappropriate antimicrobial use.[40]
Symptoms and perception of illness severity
With regard to presenting symptoms and self-perceived illness severity, patients
presenting with respiratory symptoms were significantly more likely to demand
antimicrobials. It was reported that patients who were concerned that their
illness was serious were 1.7 times more likely to want antimicrobials,[41] whereas those who considered their symptoms as severe were twice as
likely to want antimicrobials.
Attitude towards antimicrobial use in upper respiratory infections
Regarding participants who expect antimicrobials, Said and co-workers showed that
70.9% of the participants consult a physician when they develop upper
respiratory tract infection, while only 28.1% reported expecting antimicrobials
in a primary healthcare setting.[30] These results are in agreement with internationally published
studies[42-44] and lower
than those of other studies[44,45] in Hong Kong and Boston,
where the proportion who requested antimicrobials ranged from 36 to 39%,
respectively.Demanding antimicrobial is strongly associated with belief, e.g. patients who
knew that upper respiratory tract infection resolves on its own were
significantly less likely to demand antibiotics. Many reports have revealed that
patient’s expectation is an important factor for antimicrobial prescribing and
that antimicrobials are more likely to be prescribed under patient
pressure.[46-48] In
addition, physicians often prescribe antimicrobials because they perceive that
patients demand them despite their view that antimicrobials are not needed.[49]Physicians, generally, overestimate patients’ expectations of antimicrobials and
thus overprescribe antimicrobials thinking that they are doing that in the
interest of the patient–physician relationship and patient
satisfaction.[50,51] Overprescribing by physicians even in the absence of proper
indications due to diagnostic accuracy, patient’s demand and lack of knowledge
with regard to best therapies are factors contributing to the increase of
antimicrobial resistance.[52,53]
Practice related to antimicrobial use in upper respiratory infections
upper respiratory tract infections are by far the most common diagnosis for which
antibiotics are prescribed in the outpatient setting, accounting for nearly 80%
of all such prescriptions.[54,55] A study conducted locally
by Adeel et al. found that 45% of the patients had an inappropriate indication
for antimicrobials for upper respiratory tract infection in private clinics in Qatar.[31] The reason for this is unclear, but it could be because of awareness of
the emergence of antibiotic resistance or physicians being more responsive to
the patient’s expectation for antimicrobials. A study in India revealed that
antimicrobial prescriptions for acute, uncomplicated respiratory tract
infections were common in primary care settings, less so in the public sector
(45%) than in the private sector (57%).[56] Similarly, the antimicrobial-prescribing rate for upper respiratory tract
infection was 57.7% in private primary care which also is of higher rate than in
public in Malaysia. Moreover, private clinics in Malaysia contributed 87% of the
total antimicrobials prescribed (in primary care), and upper respiratory tract
infection accounted for half of these prescriptions.[57] This goes in agreement with surveys undertaken in Pakistan, India and
several African countries which have pointed to antibiotic overprescribing which
happened more in private than in public clinics.[58-60]Studies in middle and low-income countries reported minimal adherence to
guidelines and diagnosis accuracy in private compared with the public
sector.[61-63] However,
lower rates were found in the Netherlands and Hong Kong.[64,65]
Behavioural interventions and peer comparison reports can lead to a decrease in
improper antimicrobial prescriptions, even when prescriptions are not restricted
and regardless how physicians are being paid.[32] Moreover, it was reported that educational interventions were associated
with a decrease in inappropriate prescriptions in two-thirds of the studies reviewed.[66] Application of such programs may be beneficial in the State of Qatar to
reduce inappropriate antimicrobial use.Adeel et al. found that emergency medicine physicians registered the highest
number of inappropriate prescriptions (74%).[31] Emergency physicians may have fewer adherences to guidelines given the
high-volume nature of the emergency department. Relationships in the emergency
department between patients and doctors are episodic, and hence patients may be
less willing to accept advice on antimicrobial consumption.Broad-spectrum antibiotics are used too often when a narrow-spectrum antibiotic
would have been just as effective.[64] This misuse of antimicrobials has led to the development of
antibiotic-resistant bacteria. Adeel et al. reported that cephalosporins were
the most commonly prescribed group of antimicrobials in the private sector,
followed by penicillins, macrolides and fluoroquinolones. Also, nearly 5% of
prescriptions were for intravenous antimicrobials and about a quarter of the
intravenous prescriptions were for inappropriate indications.[31] However, the reasons were unclear. It could be the prescribers’ belief
that the illness was more serious, or it could be a perception that intravenous
antimicrobials are more potent or effective. Whether patients had such options
with regard to prescriptions was not known. Also, a survey at private clinics in
India reported that cephalosporins were mostly prescribed, followed by
levofloxacin, ofloxacin, and others for acute, uncomplicated respiratory tract
infections. However, in the Netherlands, tetracyclines and amoxicillin were
mostly used, followed by macrolides and amoxicillin/clavulanate among
prescriptions for all respiratory infections.[65] Also, studies from Ireland[67] and Poland[68] have shown a different pattern of antibiotic use for respiratory tract
infections. In comparison with Adeel et al.’s study,31 excessive use
of those types of antimicrobials in private settings highlights the need for
more interventions targeting prescribers and guidelines adherence.There have been few initiatives so far to assess quality of outpatient
antimicrobial prescribing.[69] These patterns were most easily observed and evaluated using two simple
quality indicators of childhood community-based antimicrobial prescribing, the
Amoxicillin Index and the Amoxicillin to Broad-spectrum Antibiotic Ratio.[70] In Qatar, application of such quality indicators as total antimicrobial
prevalence of use and the two new paediatric-specific quality indicators may
assess in optimising antimicrobial-prescribing policies, and set national
interventions to reduce and improve antimicrobial prescribing.Regarding practice of antibiotic use at medical intensive care unit, a local
study conducted by Hanssens et al. reported respiratory infections were the most
common ones. In addition, it was revealed that 76% of the patients admitted for
more for >48 h at medical intensive care unit and clinically suspected of
having an infection were prescribed antimicrobials.[32] A European study in an medical intensive care unit setting revealed a
more than 25% lower rate (62%) of antimicrobial usage for presumed or proven infections.[71] Prevalence studies on the use of antimicrobials in ICU over the last
decade revealed similar findings.[72,73] Data from other countries
showed 60%–75% rates of antimicrobial prescription in the ICU.[32,74] Moreover,
other studies from Europe revealed an average antimicrobial use of
58%–61%.[73,75] The number of antimicrobials prescribed per patient (2.09
per prescription) was similar to that described in other studies.[76] As in other studies, Hanssens et al. showed that respiratory infections
were the most frequently observed microbiologically proven infections (68%).[32] Similarly, respiratory infections were the most common and accounted for
almost 50% of all the antimicrobials prescribed in intensive care unit. Hence,
preventing respiratory tract infections is considered to be the most
cost-effective method of reducing antimicrobial use.[73]Studies have also shown that the prescription of antimicrobials was inappropriate
in 22% to 65% of the patients that received treatment.[77] It was pointed out that the threshold of suspicion of infection was much
lower in Hanssens et al.’s study population.[32] Furthermore, consistent with an European study,[71] observations suggested that despite the many microbiological cultures
taken, and regardless of the isolated pathogen and its sensitivity pattern,
results barely had any impact on the antimicrobial treatment at the medical
intensive care unit, and the empirical therapy was continued. This could be due
to a low potential for microbiological diagnostic procedures by itself, or
inappropriate microbiological investigations requested by the medical intensive
care unit team. Further evaluation is needed to determine the reasons. Factors
contributing to this phenomenon are the absence of any proven cultured pathogen,
and the short stay at medical intensive care unit for the majority of patients.
These findings clearly highlight the need for a review of
antimicrobial-prescribing policies as well as the monitoring of the use of
antimicrobials.Hanssens et al. reported that ceftriaxone was the main antimicrobial prescribed,
and this antimicrobial is considered the commonest drug upon admission in this
medical intensive care unit. Over half of patients received ceftriaxone.[32] In comparison, 44% of patients on antimicrobials received cephalosporins
in the European Prospective Investigation into Cancer and Nutrition (EPIC) study
as compared with only 8% in another study.[73] Several conditions are known to mimic the signs of infection, especially
in seriously ill patients.[78] Therefore, antimicrobials will often be prescribed inappropriately. A
more widely accessible strategy to limit the antibiotic use in medical intensive
care unit is to initiate a broad-based empirical therapy, which is subsequently
scaled-down upon availability of the microbiological cultures. An appreciable
reduction in antibiotic consumption could be achieved either by preventing
infection or by shortening the duration of antimicrobial treatment.
Limitations
A number of limitations of the present review should be highlighted. Studies were
each derived from one centre in Doha, which may affect the generalisability. Under-
or over-estimation of inappropriate use was expected as a result of exclusion of
non-Qatari nationals. However, national outpatient data in the private sector with a
large number of claims was used which enhanced the strength of the study.The review explored all published papers at different settings. This showed the
practice of antibiotic prescribing among different physicians and population groups.
There is a need for further and more recent published studies. Also, as there was
limited data about potential associations between patients’ factors and
antimicrobial prescribing at the individual level, more studies are needed to
explore the effect of different factors on providers and patients for antimicrobial
prescribing.
Recommendations
The following recommendations are suggested:
National policies and guidelines for antimicrobial resistance
Findings clearly highlight the need for a review of antimicrobial policies and
guidelines adherence as well as monitoring of antimicrobial use in all
healthcare settings. Guidelines adherence by physicians especially those who
work at private clinics will contribute to a decrease in the number of
prescriptions.
Healthcare settings and providers
Physicians should focus on providing reassurance and information and reduce
unwarranted antimicrobial prescribing. This will lead to reducing the problem of
antimicrobial resistance. Also, this will result in a decrease in the number of
future revisits for upper respiratory tract infections and a decrease in the
workload on healthcare settings without jeopardising patient satisfaction and
quality of care.Strengthening communication between medical teams and microbiologists to enhance
antimicrobial strategies and ensure appropriate antimicrobial prescribing to
limit unnecessary antimicrobial use is imperative. This step should be
implemented in all units within healthcare facilities such as medical intensive
care unit, emergency department, etc.Promoting public education is an important tool against inappropriate
antimicrobial prescriptions. Patient education could be conducted through
brochures, pamphlets, videos and counselling at clinics. Moreover, studies to
measure effectiveness of both clinic and community-wide health education
programmes on appropriate use of antimicrobials for upper respiratory tract
infections are needed.
Quality indicators
As a tool for referencing the antimicrobial-prescribing trend, especially at the
ambulatory care settings, this would aim to highlight those prescribing patterns
and practice that deviate from the guideline indications.
Public health communication
Health programmes to promote public education about antimicrobials by public
media such as TV, radio and social media can be quite useful in connecting more
closely with the public and disseminating correct knowledge about the need for
antibiotics.
School- and community-level engagement
It has been proven that school-based health education programmes significantly
increase knowledge among middle school children in different countries.
Implementing such programmes into the school syllabus will promote best use of
antimicrobials from a young age.
Further research
There is a need for further studies to determine population-based rates as well
as knowledge and practice regarding antimicrobial use for upper respiratory
tract infections across the country.
Conclusion
This is the first systematic review conducted exploring the topic and a number of key
findings were highlighted in the review. It can be concluded that overprescribing is
common in all settings. The review will assist policy makers in Qatar to establish
future effective interventions in order to improve the inappropriate use of
antimicrobials. There is a need for further studies in the field to explore the
public’s knowledge, rates and factors associated with antimicrobials
prescribing.
