Abstract
Objective: This descriptive observational cross-sectional study aimed to assess the general population's
awareness, attitudes, and behaviours towards proton pump inhibitor (PPI) usage, as well as their knowledge
about associated side effects, in the Qassim region of Saudi Arabia.
Methods: An autonomous online survey was conducted from June 15, 2023, to September 1, 2023, using
social media. The survey targeted adult residents of Qassim and collected a total of 1090 respondents. Data
analysis employed descriptive statistics, chi-square tests, and probit regression using R version 4.3.1
(RStudio, Boston, MA). A significance level of p<0.05 was utilized to interpret the results.
Results: A total of 1050 samples, limited to residents of Qassim, were analyzed. Significant associations were
observed between awareness of PPIs and factors such as side effects (adjOR = 1.19, 99% CI: 1.08-1.31),
widespread PPI use (adjOR = 1.24, 99% CI: 1.12-1.38), PPI usage (adjOR = 2.47, 99% CI: 2.18-2.82), and
optimal PPI timing (adjOR = 1.30, 99% CI: 1.13-1.50). Additionally, age, educational attainment, and
employment in the medical field significantly influenced awareness gaps related to potential side effects,
PPI prevalence, adherence to medical prescriptions, and optimal timing for PPI usage.
Conclusion: The current study concludes that a significant portion of individuals in the Qassim region lack
awareness regarding the potential side effects of PPI usage. Comprehensive healthcare education is required
to bridge awareness gaps regarding PPIs and foster informed medication practices. By grasping the
intricacies of individual perceptions, medical engagement, and demographic factors, healthcare providers
and policymakers can collaboratively empower individuals in the Qassim region to make informed choices
regarding their health and medication usage.

Introduction
Proton pump inhibitors (PPIs), introduced in 1989 with the discovery of omeprazole and now globally
prevalent due to their proven efficacy and tolerability, are a common prescription choice. However, their
uptake is influenced by attitudinal factors, where positive perceptions encourage usage, while concerns
about side effects, long-term use, or dependency can lead to hesitancy [1]. Physicians, including
geriatricians, significantly affect PPI prescription rates, with studies revealing correlations between their
prescription behaviour, hospital grade, education level, and participation in educational programmes,
highlighting clinical limitations [2,3]. Negative attitudes contribute to PPI overuse, as healthcare providers
in one study believed it was widespread due to insufficient understanding of side effects among doctors and
patients [4]. Behavioural factors, including effective communication and higher health literacy, positively
influence PPI adherence, while nurses' attitudes towards PPI usage vary, with regional differences [4].
Compliance with prescribed PPI regimens is crucial; one study found incorrect administration, emphasizing
the need for evidence-based interventions. Perceived needs influence usage, driven by symptom severity or
medical history [5].
Literature review
The number of people relying on PPIs in the United Kingdom has risen significantly, from 32.6 million in
2008 to 60 million in 2018, according to data from [6]. The over-utilization of these medications is regarded
as a substantial financial burden for both the government and the general community, resulting in an
estimated cost of around £2 billion per year on a global scale, as indicated by research conducted by
Aljahdli’s [7].

Among the General Population in the Qassim Region, Saudi Arabia. Cureus 15(10): e46749. DOI 10.7759/cureus.46749
PPIs bind permanently to the gastric hydrogen-potassium ATPase pump, commonly called the proton pump
in stomach parietal cells, deactivating it and inhibiting gastric acid secretion, a mechanism explained by
Aljahdli [7]. They are extensively used to treat and prevent upper gastrointestinal tract conditions, including
peptic ulcers, GERD, eradicating Helicobacter pylori, managing dyspepsia, countering NSAID-induced
ulcers, and addressing Barrett's oesophagus, as discussed by Ahmed and Clarke [8].
In their comprehensive study on GERD pathophysiology, diagnosis, and treatment, Chen and Brady [9]
emphasized the need for most PPIs to be taken 30 minutes before meals, except for omeprazole, which can
be taken before or after meals. The clinical investigation by Yoon et al. [10] regarding the impact of
tegoprazan 50 mg (a potassium-competitive acid blocker) on healthy males found that meal timing had no
clinically significant effects on its pharmacokinetics, efficacy, or safety, concluding it can be administered
without meal considerations. Additionally, the study by Laine et al. [11] in the USA on H. pylori-negative
subjects evaluating a potassium-competitive acid blocker (vonoprazan) and a PPI (lansoprazole) reported
that PPIs are more effective when taken shortly before meals.
The evidence suggests frequent overuse of PPIs, with 25-70% of prescriptions lacking proper indications,
often due to their accessibility as over-the-counter drugs, as explored by Jaynes and Kumar [12]. Excessive
PPI use surpasses documented gastrointestinal symptom cases. While PPIs effectively treat acid-related
conditions, their excessive off-label use leads to severe adverse events [13]. Expert analysis by Savarino et
al. [14] highlights ongoing inappropriate PPI use in Europe, driven by improper hospital prescriptions and
post-discharge continuation.
In a Spain-based study by Savarino, over 50% of PPI prescriptions were deemed inappropriate, spanning
hospitals and primary care settings, as revealed in their examination of PPIs' suitable application [15]. In a
comprehensive systematic review, Scarpignato et al. [16] noted that despite overuse and inappropriate
employment of PPIs challenging their safety profile, adverse events typically occur at a frequency of 1-3%,
including headaches, nausea, abdominal pain, constipation, flatulence, diarrhoea, rash, and dizziness.
Prolonged PPI use alters gastric pH, fostering microorganism growth and increasing gastrointestinal
infection risk. PPI use is linked to osteoporosis and fractures. The Beers criteria recommend limiting PPIs in
elderly patients to eight weeks, supported by Freedberg's research [17]. Analyzing UK Health Improvement
Network (THIN) data, Freedberg et al. [18] found higher PPI exposure in young adults compared to children,
indicating a greater fracture risk among young adults.
Despite PPIs being generally well tolerated, a range of studies have highlighted their link to various adverse
effects. According to certain investigations, patient awareness concerning the adverse effects linked to PPIs
remains limited, indicating that a significant majority of participants were oblivious to any potential
adverse effects of these medications, as indicated in the works of Hamurtekin et al. [19] and White et al. [20].
Socio-demographic status significantly influences sustained PPI use, as shown in the Netherlands study by
Van Boxel et al. [21]. Low educational attainment correlates with chronic PPI utilization, emphasizing
education's role in health-related attitudes and knowledge [21]. Similarly, a nationwide Danish cohort study
by Haastrup et al. [21] linked long-term PPI use to lower income and education levels.
Despite the acknowledged effectiveness of PPIs, these scenarios have collectively contributed to the
widespread occurrence of improper PPI utilization. A study conducted within an academic hospital in Saudi
Arabia documented a substantial prescription rate of 57.6% for PPIs, as reported by Basheikh [22].
In a comprehensive medication usage study conducted by AlKhamees et al. [23] on the top ten most
commonly used drugs in Saudi Arabia from 2010 to 2015, antibiotic and analgesic use predominated,
followed by PPIs and anti-diabetic medications. The consumption of anti-hyperlipidemic drugs and
treatments for erectile dysfunction followed. The study also noted an increasing trend in the use of
pantoprazole and esomeprazole in Saudi Arabia during this period. While pantoprazole had higher overall
usage than esomeprazole, there was a period between 2012 and 2013 when pantoprazole surpassed
esomeprazole in utilization.
The study by Asdaq et al. [24] in Riyadh, Saudi Arabia, involving medical doctors, pharmacists, and nurses
from diverse public and private hospitals, found that individuals with higher education, middle-aged
individuals, and those with more professional experience had greater knowledge levels. Pharmacists and
nurses showed lower reliance on PPIs compared to doctors. The research also revealed a positive correlation
between healthcare professionals' attitudes, knowledge, and behaviour regarding PPI usage in Saudi Arabia.
Another study by Alasmari et al. [25] focused on physicians, pharmacists, and clinical pharmacists in Saudi
Arabia, revealing significant disparities in PPI awareness, with more reporting poor knowledge. AlShammari
et al. [26] studied adults in Saudi Arabian malls, assessing over-the-counter PPI usage. Initially, low
knowledge and awareness improved through pharmaceutical advertising, enhancing public understanding
of gastroesophageal reflux disease. (GERD) Alzahrani and Al Turki [27] studied Riyadh residents trained in
family and internal medicine. Findings showed insufficient GERD management knowledge and age-linked

better understanding. Most residents are prescribed PPIs before meals, but for a shorter duration.
Therefore, the purpose of this study is to assess the awareness, attitude, and behaviour regarding PPI usage
among the general population of the Qassim region in Saudi Arabia and to assess if there is long-term
improper use of PPIs in the population and their knowledge about its side effects through a cross-sectional
study design using a validated self-administered questionnaire.
Materials And Methods
The present investigation employed a descriptive observational cross-sectional study design. An
autonomous online survey was undertaken amongst adult residents of Qassim (age ≥ 18). This survey was
administered via diverse social media platforms from June 15, 2023, to September 1, 2023. All readily
accessible populations conforming to the eligibility criteria were extended invitations to participate in the
inquiry.
A targeted minimum sample size of 385 was determined through the utilization of the following formula: n =
(z)² p (1 − p)/d², wherein the sample size, denoted as 'n', p = 50%, and the confidence level is set at 95%, thus
yielding a Z score of 1.96. The margin of error (E) is established at 5%, and the population size stands at
100,000. The non-probability sampling method, namely convenience sampling, was implemented. The study
participants were encompassed based on their convenient accessibility and willingness to partake in our
research endeavour.
The study encompassed individuals who, having reached the age of 18 years or more, were inhabitants of the
Qassim region. The recruitment process focused on those who willingly signed the informed consent
document. An ethical approval letter was sought from the Qassim University IRB with the number-.
A validated questionnaire, translated into Arabic, was employed to gauge the populace's awareness, attitude,
and conduct concerning the usage of PPIs and their understanding of associated side effects. Various
sections of the questionnaire encompassed demographic details, knowledge, and attitudes towards PPIs
(their usage and adverse effects). Table 1 presents the survey questions and their corresponding categories.
The data underwent meticulous cleansing and scrutiny to rectify any potential errors or discrepancies. The
analysis of the data was carried out using the R programming language, specifically version 4.3.1 (RStudio,
Boston, MA) [28]. The relevant descriptive statistics were computed and then summarized in terms of
frequency, percentage, and mean values. The analysis of categorical variables, stratified by demographics,
was conducted using the Chi-square test. Odds ratios, both unadjusted and adjusted, were calculated via
probit regression to assess the risk factors. Statistical significance was indicated for differences where the pvalue was less than 0.05.

Descriptive statistics
Table 2 presents a comprehensive overview of socio-demographics categorized by awareness of
antacids/PPIs. Notably, the demographics were not classified based on specific antacids/PPIs such as
Nexium, Esomeprazole, Pantoprazole, Omeprazole, Omez, or Gasec. The study included a total of 1090
participants in the sample. It is important to note that the study specifically focused on residents of the
Qassim region. After data cleaning, 32 participants who were non-residents of Qassim were removed,
resulting in a final sample size of 1058 participants. This final sample size was used for conducting the probit
analysis.
Figure 1 provides a comparative visualization of the awareness of PPIs and their usage. The comparison is
established among individuals who have never used them, those who have used them with medical
consultation, and those who have used them without medical consultation.

Discussion
Proton pump inhibitors are frequently prescribed medications for managing GERD and related conditions.
Despite their established effectiveness, concerns have arisen regarding potential side effects and misuse.
This study assesses the awareness and understanding of PPIs among the general population in Saudi
Arabia's Qassim Region. The research examines PPI awareness, side effects, widespread usage, and optimal
timing for antacid/PPI use.
In the realm of PPIs and their potential side effects, the current study unveils a striking connection. It delves
into the relationship between participants' awareness of antacids and PPIs and their perspectives on the
potential short-term side effects of PPIs. An adjusted odds ratio (adjOR) of 1.19 indicates that those
believing in minimal side effects from short-term PPI use are about 1.19 times more familiar with these
medications compared to others. The majority of participants (34.3%) who were aware of PPIs believed that
short-term usage of PPIs would not lead to side effects. In total, 52.6% perceived that short-term PPI usage
was unlikely to cause side effects, while 14.9% believed it could, leaving 32.4% uncertain, indicating limited
recognition of PPIs' side effects. These findings parallel Aljahdil's [7] study, which found that most
participants (43.6%) were unaware of the side effects. The present study documented that a majority of
patients (22.8%) lacked awareness of any side effects linked to PPI usage, in contrast to those who
pinpointed nausea and vomiting as the primary side effects of PPI usage (14.5%). These results concur with
the observations made by Hamurtekin et al. [19] and White et al. [20] studies, both of whom highlighted that
most patients were not unaware of potential adverse effects associated with PPIs. While participants'
medical backgrounds did not yield statistically significant differences, the age category of 21-30 years
showed notable results. Within this group, individuals were more likely to hold the belief that short-term PPI
use does not lead to side effects, distinct from other age groups. Notably, this correlation was not strong in
other age brackets due to potential variations in information exposure, health beliefs, or generational
perspectives. Similarly, the education-level analysis highlighted a significant adjOR for the bachelor's degree
category (1.24). This suggests that individuals with a bachelor's degree were likelier to know about
antacids/PPIs when perceiving minimal side effects. This emphasizes education's role in understanding
medication usage and side effects, with implications for healthcare communication and patient education.
Awareness of antacids/PPIs can influence perceptions of the extent of PPI usage. Familiarity with
antacids/PPIs enhances understanding of their purposes, benefits, and risks. This awareness informs
viewpoints on suitable PPI use scenarios, shaping perceptions of their prevalence. In this study, the results
revealed a statistically significant correlation between participants' awareness of antacids/PPIs, as well as
their perceptions of the extent of PPI usage. The adjOR of 1.24 indicated that individuals who believed in

extensive PPI usage were around 1.24 times more likely to have familiarity with these medications,
compared to those whose beliefs did not match this perspective. The ongoing study has unveiled a
compelling connection between PPI awareness and their utilization within the Qassim region (45.1%), in
contrast to those unaware of PPIs (20.6%). These figures find their roots in the accessibility of PPIs as overthe-counter medications, as noted in the study by Jaynes and Kumar [12]. Furthermore, these findings
underscore the prominence of PPI usage, ranking among the top ten most frequently employed drugs in
Saudi Arabia, a validation documented in the study by Alkhamees et al. [23]. The five primary reasons for the
widespread usage of PPIs among the residents of Qassim were heartburn (36.6%), gastroesophageal reflux
disease (27.5%), gastritis (12%), H. pylori infection (6.5%), and peptic ulcers (5.2%). Although the
percentages were not closely aligned, a similar pattern in the reasons for PPI usage in Saudi Arabia was
reported in the AlJahdli [7] study: heartburn (56.4%), gastroesophageal reflux disease (51.1%), gastritis
(21.8%), H. pylori infection (20%), and peptic ulcers (15.7%).
Digging deeper, the data were split by participants' education levels: less than high school, high school,
diploma, bachelor's, and higher degrees. Notably, adjOR for high school (1.25), diploma (1.48), and
bachelor's (1.26) showed significance. Importantly, bachelor's degree holders showed a highly significant
association compared to high school and diploma qualifications. These findings highlight the link between
participants' education and awareness of antacids/PPIs in PPI usage perceptions. The strong significance
among bachelor's degree holders underscores higher education's role in shaping understanding. These
insights imply tailored healthcare communication strategies for diverse educational backgrounds. This
finding is in agreement with the studies by Aljahdli [7] and Asdaq [24] in Saudi Arabia and the Haastrup et al.
[29] study in Denmark, all of which demonstrated significant associations between awareness of PPIs, their
prior usage, and educational attainment. The study reported that knowledge of PPIs was statistically
significant among individuals with a bachelor's degree.
Regarding the perception of widespread antacid/PPI usage, only the adjOR for the age groups 21-30 years
(1.22) and 41-50 years (1.46) showed statistical significance. This implies that individuals within these age
brackets may hold different viewpoints about the prevalence of PPI usage in the Qassim region, significantly
affecting their awareness of antacids/PPIs. This could stem from generational disparities in exposure to
health information, evolving medical recommendations, or varying health concerns. Younger individuals
(21-30 years) might be better informed due to greater access to online resources, while those in the 41-50
age group might be influenced by their life stage, leading to heightened awareness. These findings offer
valuable insights into age-related variations in perceptions and awareness of PPI utilization. This discovery
aligns with the results of the study by Aljahdli et al. [7], which also found a noteworthy correlation between
older participants and a greater frequency of PPI knowledge in comparison to participants of younger age;
the study by Van Boxel et al. [21] associated low educational attainment with chronic utilization of PPIs; the
study by Alzahrani et al. [27] linked better knowledge on management of GERD to age; and the study by
Freedberg et al. [18] associated the use of PPIs with a high risk of fracture among young adults in
comparison to children.
When participants were categorized by their medical field background, the associations were as follows:
among "yes" responders, the adjOR was 1.06, and the p-value was 0.626. Among "no" responders, the adjOR
was 1.27, with a p-value of 0.0002. This indicates that participants with medical field experience had a
higher adjOR for the "no" response, showing a clear link between their background and perceptions of PPI
prevalence. Conversely, participants without medical experience had a lower adjOR for the "yes" response.
These findings suggest participants' medical background could influence their views on PPI usage in Qassim,
impacting their antacid/PPI awareness understanding. This finding resembles the results of Aljahidi's [7]
study, which indicated that being employed in the medical field was linked to a greater level of awareness
and usage knowledge regarding PPIs.
In the realm of participants' awareness of antacids/PPIs and their previous medication use, a significant and
captivating connection comes to light. The adjOR of 2.47 illuminates this revelation, highlighting that those
who have experienced these medications are approximately 2.47 times more likely to be acquainted with
them compared to non-users. The exploration continues with a revelation of statistically significant
prevalence rates of PPI utilization with medical consultation (p < 0.001) in the Qassim region. Among those
previously aware of them, the prevalence stands at 24.5%. Conversely, the prevalence of usage without
medical consultation is 9% (p = 0.006), while the prevalence among those initially unaware of PPIs reaches
24.3% (p = 0.05). These prevalence rates mirror those reported in Aljahdli's [7] study in Saudi Arabia. There,
the prevalence of PPI usage with medical consultation was 25.7%, and usage without medical consultation
was reported at 10.3%. The journey into the interconnected world of antacids/PPIs and their usage
continues, shedding light on an essential facet of healthcare understanding. The usage findings correlate
with the study by Basheikh et al. [22] in Saudi Arabia, which revealed a significant prescription rate for PPIs
within an academic hospital. Similarly, the study by Alkhamees et al. [23] documented an increasing trend in
PPI usage in Saudi Arabia. Moreover, the study by Asdaq et al. [24] conducted research in Saudi Arabia that
highlighted doctors' heightened reliance on PPIs in comparison to pharmacists and fellow doctors.
Additionally, the study by Alasmari et al. [25] explored the perspectives of physicians and pharmacists in
Saudi Arabia, identifying a higher occurrence of inadequate knowledge juxtaposed with substantial
knowledge concerning PPIs. Consequently, this current study signifies that doctors within Saudi Arabia's
Qassim region contribute significantly to the elevated prescription of PPIs for their patients, similar to what
2023 Almuzaini et al. Cureus 15(10): e46749. DOI 10.7759/cureus.46749

has been documented in Luo et al. [4] and Savarino et al. [14,15] studies.
Comparing odds ratios based on participants' involvement in the medical field showed distinct patterns.
"Yes" responders had an adjOR of 1.68, indicating a 1.68 times higher likelihood of being aware of
antacids/PPIs among users, which is similar to the results reported in the study by Aljahdli et al. [7]. In
contrast, "no" responders had a significantly higher adjOR of 2.90, suggesting a 2.90 times higher likelihood
of awareness among non-users. Non-users showed a stronger link between lack of medication use and
awareness, possibly due to active information seeking. Users might have gained awareness through personal
experiences. This dynamic underscores the role of personal experience and professional background in
shaping medication awareness. All odds ratios regarding antacid/PPI use were statistically significant across
age groups. The ascending trend in adjusted odds ratios indicated increasing awareness with age. The
significant odds ratios underscored the relationship between age and participants' awareness of these
medications, implying age-influenced familiarity. The adjOR suggested both awareness and usage increased
with age, which is similar to what was reported in the study by Aljahdli et al. [7] and Alzahrani et al. [27].
The rising trend in adjOR values across age groups indicated a higher likelihood of awareness and use as age
advanced. Statistically significant odds ratios further supported the link between age, awareness, and usage.
To delve deeper, the data were segmented by participants' educational levels: less than high school, high
school, diploma, bachelor, and higher degree. Remarkably, across all educational categories, the adjOR
showed statistical significance. However, those with lower education levels (less than high school, high
school, and diploma) exhibited a larger adjOR than those with bachelor's and higher degrees. This implies a
more pronounced use of antacids/PPIs among individuals with lower education levels, which aligns with
what was reported in Van Boxel’s [21] study. These findings underline the correlation between educational
background and awareness of antacids/PPIs in relation to PPI usage perceptions. The heightened
significance among individuals with lower education levels highlights education's potential influence on
medication usage perception. These insights suggest tailored healthcare communication for diverse
educational backgrounds.
The timing for taking PPIs varies with the medication and individual condition. Generally, PPIs are taken
before meals. They reduce stomach acid production, and taking them before eating allows for absorption
and early action before food intake. The present study revealed a statistically significant relationship
between participants' awareness of antacids/PPIs and their subjective opinions regarding the optimal time
for medication intake. The calculated adjOR of 1.30 indicated that individuals expressing opinions about
suitable medication timing were approximately 1.30 times more likely to be familiar with these medications
compared to those not sharing such opinions. Among those aware of PPIs, 37.1% recognized the need to take
PPIs before meals, 17.3% indicated after meals, and 3.6% mentioned with meals. When the data were not
segregated, PPI usage before meals was recorded at 50.9%, after meals at 41.4%, and with meals at 7.7%,
figures nearly in line with what was reported in the study by Aljahdil et al. [7: before meals (59.8%), after
meals (39.3%), and with meals (0.9%). Studies such as Chen and Brandy [9] advocated the use of PPIs before
or after meals, while Laine et al. [11] suggested their efficacy was heightened shortly before meals.
Categorized by participants' medical backgrounds, results showed: "yes" responses had an adjOR of 1.54, pvalue = 0.012; "no" responses had an adjOR of 1.21, p-value = 0.022. This suggests a medical background
might influence optimal medication timing perceptions and antacid/PPI awareness. Professionals prioritize
timing due to expertise; non-medical individuals link awareness to personal health. These findings
underscore medical knowledge's role in viewpoints and relevance for healthcare communication. The adjOR
for age groups 21-30 years (1.565) and 51-60 years (2.034) on antacids/PPIs timing was statistically
significant. These age ranges held distinct viewpoints, impacting awareness. Notably, those aged 21-30 and
51-60 had a stronger correlation between timing opinions and antacid/PPI awareness. This enhances
understanding of age-related variations in perceptions and awareness. Regarding education and optimal
timing perception linked to antacid/PPI awareness, only higher education levels showed significance. Higher
degrees had a larger adjOR than bachelor's. This highlights stronger awareness among advanced education
levels. These findings emphasize education's link to antacid/PPI awareness in medication timing
perceptions. Higher degrees' significance underscores advanced education's influence. Insights suggest
tailored communication strategies for diverse education levels.
Recommendations
The current study highlighted that a significant portion of individuals in the Qassim region lack awareness
regarding the potential side effects of antacids/PPI usage. Healthcare professionals are recommended to
acknowledge and explore patients' beliefs concerning the perceived absence of short-term PPI side effects.
Engaging in discussions about patients' perspectives on side effects presents an effective approach to
enhancing their awareness and comprehension of antacids and PPIs.
The strong association between PPI usage and its prevalence in the Qassim region might be influenced by
individual perceptions and the accessibility of over-the-counter PPIs. Based on these findings, healthcare
practitioners are encouraged to recognize the potential impact of patients' perceptions regarding PPI
prevalence in the region. Integrating conversations about patients' viewpoints on medication prevalence can
serve as a means to elevate their awareness and understanding of antacids/PPIs.

Medical practitioners were identified as the primary prescribers of PPIs, despite some individuals using PPIs
without medical consultation. Considering these findings, healthcare practitioners should prioritize
acknowledging the potential influence of prior medication usage when designing patient education and
communication strategies. Incorporating individuals' personal experiences with medication usage can
enhance the effectiveness of interventions aimed at raising awareness about antacids/PPIs.
Half of the study participants were aware of the optimal timing for PPI intake before meals, while the other
half were either uncertain or identified during meals. Given these results, healthcare practitioners are
advised to recognize the importance of patients' opinions on suitable medication timing. Incorporating
discussions about appropriate timing in patient communication can significantly contribute to augmenting
awareness and understanding of antacids/PPIs among Qassim region residents.
Conclusions
In conclusion, this study offers significant insights into healthcare awareness within the Qassim region. The
findings underscore a notable lack of awareness among a significant portion of the population regarding the
potential side effects associated with antacid/PPI usage. The study reveals a strong correlation between PPI
usage and its prevalence in the Qassim region. This link may be influenced by individual perceptions and the
easy accessibility of over-the-counter PPIs. Understanding this relationship is crucial for designing targeted
educational efforts to dispel misconceptions and improve overall awareness. Notably, medical practitioners
emerge as primary prescribers of PPIs, alongside instances of non-medical PPI use. This highlights the need
to acknowledge the pivotal role of healthcare professionals and to promote safe and informed medication
practices among the public. Regarding the optimal timing for PPI intake, a divergence of opinions exists
among participants. While half of the participants are aware of the preferred timing before meals, the
remaining participants exhibit uncertainty or identify other timings. This variation underscores the
potential for tailored communication strategies to enhance clarity around medication intake practices.
Moreover, the study demonstrates that factors such as age, educational attainment, and employment within
the medical field significantly influence awareness gaps concerning potential side effects, PPI prevalence,
adherence to medical prescriptions, and optimal timing for PPI uptake. These demographic insights can
inform the design of targeted interventions aimed at addressing specific knowledge gaps.
In summary, the findings emphasize the need for comprehensive healthcare education efforts to bridge
awareness gaps and promote informed medication practices. By understanding the nuances of individual
perceptions, medical involvement, and demographic influences, healthcare providers and policymakers can
collaboratively work towards empowering individuals in the Qassim region to make informed decisions
about their health and medication use.
