Introduction
Antimicrobials, including antibiotics, antivirals, antifungals, and antiparasitics, are used to prevent and treat infections in humans, animals, and plants [1]. Antimicrobial resistance (AMR) occurs when microbes change over time, making antimicrobials ineffective [1]. AMR can occur in microbes naturally, but it can also be induced by inappropriate use of antimicrobials or unintentional exposure [2]. This results in organisms that are very challenging to treat and have a significantly high fatality rate [1].
AMR is spreading, creating microbes that cannot be treated with existing medications. Currently, common organisms that cause different diseases, such as tuberculosis (TB), HIV/AIDS, malaria, sexually transmitted diseases, urinary tract infections, lung infections, and blood infections, can resist a wide variety of antimicrobics [2]. Two prior studies conducted in Jeddah, Saudi Arabia, showed a high prevalence of HIV and TB resistance. Regarding HIV, 41%, 16%, and 13% were resistant to nucleoside reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), and protease inhibitors (PI), respectively. While in TB, among 901 cases, drug-resistant TB was observed in 193 (21.4%) [3-4].
AMR is significantly costly, not just financially but also in terms of global health, food security, environmental well-being, and socio-economic development. At present, AMR causes approximately 700,000 deaths worldwide each year [2]. In addition, there is approximately one death every 10 minutes in Europe or the United States of America because of deadly infections caused by antimicrobial-resistant bacteria [5]. AMR is rising in almost every country [5]. However, a systemic literature review in Saudi Arabia demonstrated that, in comparison to the 1990s, there has been a significant increase in carbapenem-resistant gram-negative bacilli (GNB) over the last decade. Additionally, it also revealed an increase in the prevalence of extended-spectrum beta-lactamase-producing bacteria in Saudi Arabia, with 29% documented among Escherichia coli (E. coli) and 65% among Klebsiella pneumoniae (K. pneumoniae). Accordingly, these documented rates were associated with multiple reported outbreaks, and mortalities ranged between 11% and 40% [6].
A study in 2015 from Riyadh showed a dramatic reduction in the susceptibilities of Acinetobacter baumannii (A. baumannii) to meropenem and imipenem, where the susceptibilities were 64-81.2% in 2006 and 8.3-11% in 2012. Consequently, with carbapenem resistance, therapeutic options are extremely limited, making it a major epidemiological concern [7]. In Saudi Arabia in 2014, a national surveillance of AMR among gram-positive cocci represented a high resistance rate among Staphylococcus aureus (S. aureus), 32% were methicillin-resistant (MRSA), and among Streptococcus pneumoniae, 33% were resistant to penicillin G, and 26% were resistant to erythromycin [8].
Regarding multi-drug resistant bacteria in Saudi Arabia, there are many factors associated with its increase. It is well-established that inappropriate use of antibiotics is an important factor in the development of AMR [6]. Over-the-counter antibiotics without a prescription is another factor leading to the inappropriate use of antibiotics, which contributes to more antimicrobial resistance.
A study in 2001 was done in the eastern province of Saudi Arabia and revealed that only one pharmacy out of 88 refused to dispense medication without a prescription for patients claiming to have a UTI [9]. Another study in 2011 was done in Riyadh among 327 pharmacies and showed that 77.6% of pharmacies dispensed antibiotics without a prescription [10]. Lack of awareness is another major factor in the misuse of antibiotics worldwide [11]. Patients' knowledge, attitude, and practice (KAP) are important factors contributing to the misuse of antibiotics [11-12].
A study in the Hail region of 500 participants found that 26% got antibiotics without a prescription, only 34% finished the full antibiotic course, and 36.2% were unaware of antibiotic resistance and its rise [12]. In addition, a recent study in 2021 to assess KAP towards antibiotic use and AMR among the general public in Saudi Arabia showed an insufficient attitude toward antibiotic use. It also suggests reducing antibiotic misuse by raising awareness [13]. Low knowledge levels were also reported in a 2021 study in Jeddah, indicating the need to increase public knowledge and raise awareness [14]. Globally, in Kuwait, a KAP study on antibiotic use in 2015 [15] reported that 72.8% of the respondents had received an antibiotic prescription in the year before the survey; of those, 36% did not complete the course of treatment. Moreover, 27.5% were self-medicating primarily for cough, sore throat, and a common cold. A 2021 study conducted in Boyolali, Indonesia, revealed that most of the participants had insufficient knowledge about the proper usage, accessibility, and function of antibiotics. Male sex, low income, low educational levels, and residency in rural areas were associated with inappropriate use of antibiotics [16].
To implement corrective measures regarding antibiotics KAP, first, we need to know the level of awareness in society currently. Therefore, the aim of this study was to assess the knowledge, attitude, and practices (KAP) of the population of the western region of Saudi Arabia towards antibiotic use and antimicrobial resistance.
Materials and methods
Study design
The study design was cross-sectional and conducted using a validated questionnaire that had been developed and used in a previous study [10]. The survey was conducted during the period from June to July 2022. This survey aims to evaluate public knowledge, attitudes, and practices among people living in the western region of Saudi Arabia towards antibiotic use and antimicrobial resistance.
Study population
The study was conducted via an online questionnaire, and our target sample in this study was public adults who are Arabic and English-speaking individuals living in the Western Region of Saudi Arabia. This study excluded non-Arabic, non-English-speaking individuals and individuals living outside the Western Region of Saudi Arabia.
Sampling methodology
The sample was conducted on public people from the 1st of June to the 1st of July 2022 in the Western Region of Saudi Arabia. We obtained consent from the participants before they started filling out the questionnaire. According to OpenEpi version 3.1, the sample size should not be less than 769 participants. However, the final sample size that has been included in this study is 501. The questionnaire form is online, and it has been sent through social media platforms. It consists of four parts of close-ended type questions in the form of multiple-choice answers. It was made in Arabic and English languages. The first part included eight items of the participant's sociodemographic characteristics (gender, age, place of living, marital status, education level, occupational status, monthly income, and source of information). The second part is made up of 17 items to assess the knowledge of antibiotic use and antimicrobial agents. The third part has ten items that evaluate the attitude towards antibiotic use and AMR using a five-point Likert scale (strongly agree, agree, uncertain, disagree, strongly disagree). The fourth part is about assessing the participant's practice towards antibiotic use and AMR, and it is composed of 17 questions using a five-point Likert scale (never, rarely, sometimes, often, always). Data was collected from any participant who met our criteria. The electronic data collection forms did not show any nominative information. Data was automatically entered into the Excel sheet (Microsoft, Redmond, Washington). After verification, we transferred this data to the SPSS software (IBM Inc., Armonk, New York) for analysis.
Data analysis
After the data was extracted, it was revised, coded, and fed to the statistical software SPSS version 25. The results were reported as frequency and percentages. A scoring system was adopted based on Awad and Aboud, 2015 [15]. Descriptive statistics were obtained for sociodemographic variables. The knowledge, attitudes, and practices (KAP) scores were calculated as continuous variables by summing the number of correct responses to the total statements for each category (KAP). One point was assigned to each correct response and zero otherwise. Eighty percent and above were assigned as a good score for each category (KAP), and less than 80% were identified as having a poor score. Descriptive analysis based on frequency and percent distribution was done for all variables, including participants' age, gender, education level, marital status, occupation, and income. Also, participants' knowledge, attitude, and practice items were tabulated and graphed. Cross-tabulation was used to assess factors associated with the knowledge level regarding antibiotics and antimicrobial resistance. The Chi-squared test of independence is used for testing associations.
Ethical part and confidentiality
Consent was taken from each participant in the questionnaire. The objectives of the research were explained to the study's participants. Additionally, their consent was obtained prior to participating. They were also informed that participation was entirely voluntary, and that no personal information would be requested of them. All participants' identities were kept anonymous and confidential. Responses were accessed by the research investigators only. Ethical approval was sought from the Biomedical Ethics Committee of Umm Al-Qura University (UQU).
Results
A total of 629 participants completed the study questionnaire. One hundred twenty-eight were excluded as they were not from the western region, and 501 participants were included as they fulfilled our inclusion criteria. Table 1 shows the demographic characteristics of the sample participants (n=501), females (n=379, 75.6%), and males (n=122, 24.4%). Of the total respondents, 255 (50.9%) were in the age group of 18-24 years. Moreover, the majority (354, 70.7%) had a college degree, 230 (45.9%) were students, and 303 (60.5%) of the study population earned a monthly income of less than 3000 SAR.

Figure 1 shows the percentage of responses to each of the ten attitude questions related to antibiotic use. Of the total respondents, 87.6% trusted the physician's decision when deciding not to prescribe antibiotics, and the majority (88.9%) believed that doctors should not prescribe antibiotics when not needed. Similarly, 72.6% did not agree that antibiotics should be accessed without a prescription. On the other hand, 40.5% did not agree to stop antibiotics when symptoms improved. Moreover, 24.8% disagree the use of antibiotics will speed up the recovery from a cold and cough.

Figure 2 shows the percentage of responses to each of the seventeen practice questions related to antibiotic use. Of the total respondents, 73.9% did not get antibiotics from relatives without visiting a physician, and 57.9% did not keep antibiotic stock at home in case of emergency. Moreover, the majority (73.9%) disagree to purchase antibiotics from the pharmacy without a prescription, and 77.9% disagree to change the physician for not prescribing antibiotics. However, 57.7% believe in reading the instruction on the label.

Table 3 shows an association between knowledge of antibiotics use and social-demographic variables. Knowledge and sociodemographic variables are categorical variables; therefore, the Chi-square test of independence is used for testing the association between them. Significant factors associated with knowledge were gender, age, educational level, and occupational status (p<0.05). In contrast, marital status and income have no significant association with participants' knowledge. Among significant factors, only those participants from medical jobs had better knowledge than respondents' from other occupations.

Differences in the mean score of attitude and practice towards antibiotics use related to gender were tested using the Mann-Whitney U test, which is an alternative to the independent sample t-test in case the normality assumption is not fulfilled. For other variables, nonparametric alternative to ANOVA (Kruskal-Wallis) test is used [16]. Kolmogorov-Smirnov and Shapiro-Wilk normality test results are shown in Table 4. Since p<0.05 for all the variables, which concludes that the normality assumption, is not fulfilled. Similarly, a boxplot also confirms the non-normality of knowledge, attitude, and practice score (Figure 4). Therefore, nonparametric alternatives to t-test and ANOVA are suitable for the analysis.

The mean ± standard deviation of attitude was 5.235 ± 1.99. This score was significantly (p<0.05) lower in men (4.5983 ±2.1190) than in women (5.4406±1.9144) (Table 5). The mean ± standard deviation of practice was 11.12 ± 4.37. This score was significantly (p<0.05) lower in men (8.7869 ± 0.42280) than in women (11.8813± 0.20447) (Table 5). Another significant factor of attitude and practice is age. Marital status is only significant for practice. Furthermore, the mean scores of education level, occupational status, and income were insignificant for both attitude and practice.

Discussion
This is a cross-sectional study to assess KAP towards antibiotics and AMR in the western region of Saudi Arabia. A validated questionnaire from a literature review [13] was used to collect the data. Our study showed insufficient knowledge, an inadequate attitude, and incorrect practices related to the use of antibiotics.
Among the most important findings in the knowledge part, a significant percentage of respondents had low knowledge regarding the role of antibiotics. Almost half (51.1%) of the respondents think that antibiotics can be used to treat viral infections, while 49.5% think they can be used for a cold and cough. Moreover, 41.5% agreed that antibiotics are medications used to treat any illness with fever. However, most of the respondents (88.0%) knew that unnecessary use of antibiotics leads to antibiotic resistance, and the majority (85.4%) knew that antibiotics are not considered over-the-counter drugs. This is in comparison to a previous study that was done in 2021 across all five regions of Saudi Arabia [13], which shows that 76.5% knew that antibiotics are used in cases of bacterial infection, and 74.9% knew that antibiotic resistance may be caused by not completing the course of the antibiotic. In addition, 67.5% knew that the beneficial bacteria that normally live on the skin or in the stomach/intestines might be killed by antibiotics, and only 56.9% knew that antibiotics should not be used to treat viral infections. The same study shows that 88% of the respondents had good knowledge of antibiotic use, which is higher than what we found in our study, which demonstrates that only 44.71% of the respondents had good knowledge. The low level of knowledge in our results is almost in line with a study that was done in Indonesia [16], in which only 52.98% of the respondents had good knowledge. In the Indonesian study, only 61.61% agreed that leftover antibiotics should not be used again, and only 37.0% knew that they should complete the full course of their antibiotics and that treatment should not be stopped if their illness has improved. Only 12.91% of the respondents agreed that antibiotics could not be used to treat infections due to viruses, and around 63.35% of the respondents think that antibiotics can be used to reduce fever. Inadequate knowledge was also reported in a Kuwait study [15], which showed that around 66.5% of the sample knew that antibiotics are effective against bacteria, and only 29.8% agreed that antibiotics are not used to treat viral illnesses. In the same study, around half (49%) of the respondents knew that unnecessary use of antibiotics can lead to resistance against them.
In the analysis of attitudes, more than half (59.5%) of the respondents had no problem ending an antibiotic course of treatment when their symptoms were improving, and this is concerning because not completing the course of treatment is one of the factors that can lead to the development of antibiotic resistance. Additionally, 48.7% of the respondents think that antibiotics can prevent any illness from becoming worse, and only 48.5% agree that natural sources may work better than antibiotics. Moreover, only 24.8% disagree that the use of antibiotics will speed up the recovery from a cold and cough. However, the majority (87.6%) trust the physicians' decisions to not prescribe antibiotics for their conditions. Attitudes results from the same previous Saudi study [13] showed that 92.55% of the total participants agreed to trust the physician's decision when deciding not to prescribe an antibiotic, 91.87% believed that antibiotics should not be given by doctors if not needed, and 91.33% disagreed with the accessibility of antibiotics without a prescription. On the contrary, about two-thirds (66%) did not believe that any illness could be prevented from worsening by the use of antibiotics. Additionally, 63.7% of the respondents believed that natural sources do not work better than antibiotics. The overall positive attitude score in this research was 76.80% of the respondents. Our findings were significantly lower. Only 12% of the participants in our study had good attitudes toward antibiotic use. The attitudes were no better in the Indonesian study [16]. Around 45% thought that the use of antibiotics could speed up recovery from a cold, and almost 30% were unsatisfied if they did not get antibiotics from their physician when they thought they needed them. Furthermore, approximately 35% of respondents had no problem purchasing antibiotics from pharmacies without a prescription, and half (50%) of the sample would discontinue their antibiotics as soon as they felt better. Additionally, a quarter (25%) stored leftover antibiotics for future use.
In the Kuwaiti study [15], only 57.6% showed a positive attitude towards completing the course of treatment, even if they felt better. 66.6% disagreed with buying antibiotics from a pharmacy without a prescription.
Respondents' practices towards antibiotic use showed that 26.1% get antibiotics from relatives without visiting a physician, and 42.1% expressed a negative practice of keeping antibiotic stock at home for future use. However, the majority (72.6%) agreed that antibiotics should not be accessed without a prescription, 77.9% disagreed with changing the physician for not prescribing antibiotics, and 73.9% disagreed with purchasing antibiotics from the pharmacy without a prescription. However, only 66.8% completed the course of antibiotics when they started it, and only 57.7% agreed to read the instructions on the label. Females showed better attitudes and practices compared to males. Higher income was associated with a better attitude, but it was insignificant in relation to practices. Higher levels of education had no significant effect on respondents' knowledge, attitudes, and practices toward antibiotics. Regarding practices, in the same previous Saudi study [13], most of the respondents (94.54%) disagreed with getting antibiotics from relatives regardless of the physician's prescription. 84.83% did not store antibiotics at home for future use. Additionally, the majority (92.64%) do not purchase antibiotics from the pharmacy without a prescription. Additionally, 93% of the respondents would not change their physicians if they did not get antibiotics. However, only 78% read the instructions on the label of the antibiotics. Good practices towards antibiotic use were found to be present in only 14.4% of the participants in the Saudi study [13]. A higher but inadequate level was found in our study, in which 39.12% of the participants were reported to have good practices. In the Indonesian study [16], around 40% of the respondents bought antibiotics from pharmacies without prescriptions, and 31% took leftover antibiotics to treat reoccurring symptoms. Regarding practices in the Kuwaiti study [15], around 64.7% of the respondents trusted physicians when they decided not to prescribe antibiotics, and around 30% preferred to keep leftover antibiotics for future use.
Although most of the respondents (26.1%) in our study do not purchase antibiotics without a medical prescription, many pharmacies in different regions of Saudi Arabia have been reported to be dispensing antibiotics to purchasers illegally. In 2001, a study was done in the eastern region of Saudi Arabia, in which the research team individually visited many community pharmacies complaining of urinary tract infection (UTI) symptoms. Only one pharmacy out of 88 refused to give medications without a prescription, and 80% of the given medications were antibiotics [9]. In 2011, the same approach to pharmacies was used in another study conducted in the Riyadh region. They found that out of 327 visited pharmacies, 244 (77%) illegally dispensed antibiotics [10].
The lack of sufficient knowledge about antibiotics and antimicrobial resistance leads to wrong beliefs that eventually manifest themselves as misuse and overuse of antibiotics. These incorrect practices, if not controlled, would accelerate the emergence of highly resistant organisms and their subsequent consequences. Several researchers have studied the topic of antibiotic awareness in Saudi Arabia. Recent research at the time of writing this paper was published in 2021 and studied the population of Jeddah city. Their work confirms our findings of poor KAP towards antibiotics and antimicrobial resistance in society [14].
Limitations
Efforts were made to get accurate, precise, and representative results. However, several limitations have been encountered during this work. First, the use of an online questionnaire to collect data has its own limitations. Second, the sample size for our study is small relative to the exact number needed for generalization. Therefore, all results are limited to our study participants only, and further research with a larger sample size is needed. In addition, most of the respondents to the questionnaire were females (75.6%), students (45.9%), with or studying for a bachelor's degree (70.7%). Third, respondents were not further categorized according to their cities or nationalities; rather, their responses were analyzed collectively, and the results were made for the western region entirely. These factors might have led to unintended biases in the results. However, our work gives us some understanding of the current situation and confirms the results of the previous studies that have been done on this subject globally and locally. Additional study in this field is required, with different approaches focusing on various sociodemographic traits and different regions of Saudi Arabia.
Conclusions
The purpose of this study was to assess public knowledge, attitudes, and practices (KAP) toward antibiotic use and antimicrobial resistance. We concluded that most of our study participants had poor overall KAP. Our results highlight the knowledge gap regarding antibiotics and their appropriate usage. Thus, interventions need to be implemented to improve public KAP in this area. Some of the suggested interventions include educational health campaigns for the public that aim to promote awareness and enhance good practices. Moreover, enforcing more strict regulations to control the non-prescription dispensing of antibiotics is critical. However, further research on this topic is required to ensure that society is progressing in the right direction.
