Prevalence and predictors of polypharmacy and comorbidities among patients with chronic obstructive pulmonary disease: a cross-sectional retrospective study in a tertiary hospital in Saudi Arabia.

OBJECTIVE: This study aimed to determine the prevalence of polypharmacy, comorbidities and to investigate factors associated with polypharmacy among adult patients with Chronic Obstructive Pulmonary Disease (COPD). METHODS: This was a retrospective single-centre cross-sectional study. Patients with a confirmed diagnosis of COPD according to the GOLD guidelines between 28 February 2020 and 1 March 2023 were included in this study. Patients were excluded if a pre-emptive diagnosis of COPD was made clinically without spirometry evidence of fixed airflow limitation. Population characteristics were presented as frequency for categorical variable. Logistic regression analysis was used to identify predictors of polypharmacy. RESULTS: The study sample included a total of 705 patients with COPD. Most of the study sample were males (60%). The mean age of the study population was 65 years old. The majority of the study population had comorbid diseases (68%), hypertension and diabetes were the most common co-existent diseases. Around 55% of the study sample had polypharmacy. Females were significantly less likely to be on polypharmacy compared to males (OR = 0.68, 95% CI = [0.50-0.92], P-value = 0.012)). On the other hand, older patients aged 65.4 or more (OR = 2.31, 95% CI = [1.71-3.14], P-value ≤ 0.001), those with high BMI (≥ 29.2) (OR = 1.42, 95% CI = [1.05-1.92], P-value = 0.024), current smokers (OR = 1.9, 95% CI = [1.39-2.62], P-value ≤ 0.001), those who are receiving home care (OR = 5.29, 95% CI = [2.46-11.37], P-value ≤ 0.001), those who have comorbidities (OR = 19.74, 95% CI = [12.70-30.68], P-value ≤ 0.001) were significantly more likely to be on polypharmacy (p ≤ 0.05). CONCLUSIONS: Polypharmacy is common among patients with COPD. Patients with high BMI, previous ICU hospitalization and older age are more likely to have polypharmacy. Future analytical studies are warranted to investigate outcomes in patients with COPD and polypharmacy.

Potential Applications of Artificial Intelligence (AI) in Managing Polypharmacy in Saudi Arabia: A Narrative Review.

Prescribing medications is a fundamental practice in the management of illnesses that necessitates in-depth knowledge of clinical pharmacology. Polypharmacy, or the concurrent use of multiple medications by individuals with complex health conditions, poses significant challenges, including an increased risk of drug interactions and adverse reactions. The Saudi Vision 2030 prioritises enhancing healthcare quality and safety, including addressing polypharmacy. Artificial intelligence (AI) offers promising tools to optimise medication plans, predict adverse drug reactions and ensure drug safety. This review explores AI's potential to revolutionise polypharmacy management in Saudi Arabia, highlighting practical applications, challenges and the path forward for the integration of AI solutions into healthcare practices.

Knowledge of Antibiotic Use and Resistance Among Medical Students in Saudi Arabia.

Introduction: The World Health Organization (WHO) has placed great importance on providing thorough, hands-on training to medical students regarding responsible and appropriate antibiotic prescription. Accordingly, this study aims to gain a better perspective on the knowledge of antibiotic use and resistance among medical students in Jeddah, Saudi Arabia. Methods: A questionnaire-based cross-sectional study was conducted among medical students in Jeddah, Saudi Arabia, from 1 September to 30 November 2023. The categorical variables are presented as frequencies and percentages. Mann-Whitney and Kruskal-Wallis tests were used to compare the outcomes, and generalised linear regression models were constructed to predict the students' knowledge of antibiotics and antibiotic resistance. A p-value of < 0.05 was taken to indicate statistical significance. Results: The study included a total of 353 medical students. First-year medical students represented 28.60% of the participants, while females represented 76.80%. Most participants (92.40%) agreed that antibiotics are effective against bacteria, whereas only 25.20% agreed about antibiotics' effectiveness against viruses. More than half of the participants (53.80%) believed that bacterial infections can be resolved without antibiotics. A significant majority (78.20%) agreed that the unnecessary use of antibiotics makes them less effective. More than half of the participants (56.90%) acknowledged that infections caused by resistant bacteria are increasing in Saudi Arabia, and two-thirds (75.10%) believed that healthcare workers could effectively reduce antibiotic resistance in Saudi Arabia. Male students had low knowledge about antibiotics [Beta = -1.429, 95% CI (-2.618, -0.241), P value = 0.019]. Conclusion: Improving the curriculum by incorporating topics like resistance mechanisms and responsible antibiotic usage can address the knowledge gap among male students. This comprehensive training, utilizing various educational methods, is essential for fostering responsible antibiotic practices among future healthcare professionals.

Prescribing Renally Inappropriate Medication to Hospitalized Geriatric Patients in Makkah, Saudi Arabia.

Introduction: As a result of the physiological decline in renal function that comes with age and the common failure to recognise renal insufficiency, older adults aged 65 and above are at increased risk of receiving medications that are inappropriate for their level of renal function which in turn lead to increased risk of adverse effects. Little is known about how many older adults receive medications that are inappropriate for their level of renal function. This study aimed to determine the prevalence of renally inappropriate medications in elderly adults by reviewing patient files and evaluating the appropriateness of medication doses relative to renal function in patients aged ≥ 65 years at inpatient healthcare departments. Methods: A retrospective cross-sectional study of patients aged ≥ 65 years was conducted, covering cases from 2015 to 2021. Patient's medical records were reviewed, their renal function and medications lists were evaluated, determined whether they had been prescribed at least one renally inappropriate medication based on drug-dosing recommendations for different degrees of renal function. Results: A total of 317 elderly inpatients were included, 10% of whom had received inappropriate doses relative to their renal function. Glomerular filtration rate was associated with inappropriate dosing in this study. Of the patients CKD stage 5, 36.8% had at least one drug administered at an inappropriate dose, while this figure was 6.5% among the patients at CKD stage 1; this difference was statistically significant (p = 0.001). Conclusion: A notable portion of older adults may be at risk of adverse effects due to inappropriate medication dosing related to their renal function. Further studies with large samples, drug use analyses based on comprehensive geriatric references and a prioritisation of actual outcomes over potential outcomes are needed to further determine elderly adults' exposure to inappropriate drugs.

Knowledge and Perception Towards Psychotropic Drugs Among the General Population in Saudi Arabia.

Background: Mental health is crucial to overall well-being. Despite an increase in mental disorders over the past few decades, public awareness remains slow-growing, and stigmatization towards psychotropic medications persists. Therefore, this study aimed to identify knowledge and perceptions of psychotropic drugs among the general population in the Makkah Region, Saudi Arabia. Methods: A questionnaire-based cross-sectional study was conducted among adults aged 18 years old and older, living in the Makkah Region, Saudi Arabia, from 1 January to 30 April 2024. Descriptive statistics were used to describe participants' characteristics, and categorical variables were reported as frequencies and percentages. A Chi-square test was used to examine the relationships between variables. Results: A total of 717 participants were involved in the study: (52%) were from Jeddah, (25.9%) were from Taif, and (22%) were from Makkah. The mean age was 33.9 years, and 67.1% were females. Among the participants, (20.8%) had experienced a psychiatric illness, (41.7%) had a member of the family who suffered from a psychiatric illness, (39.5%) had a family member who used a psychiatric drug, and only 25 (7%) had a child suffering from a psychiatric illness. Specifically, 20.8% of those with a psychiatric illness demonstrated good knowledge (P=0.001), 16.1% of those with a family history of psychiatric illness had good knowledge (P=0.007), 16.3% with family use of psychiatric drugs had good knowledge (P=0.006), and 24.5% of those who used psychiatric drugs had high knowledge (P=0.001). Overall, (40.6%) of participants had a low level of knowledge and perception about psychotropic drugs, (47.8%) had a moderate knowledge and perception level, and only (11.6%) had high knowledge and perception. Conclusion: Psychological well-being is crucial for health, but misconceptions persist, acting as barriers that impede people from seeking and accepting necessary psychiatric care. The findings highlight the need for targeted public education and healthcare professional training to improve Confirmed understanding and reduce stigma around psychotropic drugs in Saudi Arabia. A multifaceted approach involving policy development, community outreach, and ongoing research is essential for enhancing mental health outcomes and treatment accessibility.

Toxicity of Nab-Paclitaxel Compared to Paclitaxel in a Tertiary Hospital in Jeddah, Saudi Arabia: A Retrospective Cohort Study.

Background Nanoparticle albumin-bound paclitaxel has been developed to avoid the toxicities associated with Cremophor-solved paclitaxel. Although many studies confirm this hypothesis, there is recent evidence showing no difference between paclitaxel and nab-paclitaxel in their efficacy and safety profile. This study further assesses the toxicity of both paclitaxel and nab-paclitaxel in adult patients with breast and pancreatic cancer in a tertiary hospital in Jeddah, Saudi Arabia. These toxicities include neutropenia, anaemia, and effects on kidney and liver functions. Methods The study is a retrospective cohort study done at King Abdulaziz University Hospital, Jeddah, Saudi Arabia, from January 2018 to December 2021, conducted on patients diagnosed with breast or pancreatic cancer treated with paclitaxel or nab-paclitaxel. Results There is a statistically significant difference between the two groups in developing anaemia, renal, and liver toxicity (P<0.05). On the other hand, there are no statistically significant differences in developing neutropenia between the two groups (P=0.084). Conclusions Nab-paclitaxel might not be better than paclitaxel in reducing the risk of neutropenia, anaemia, and liver toxicity, as predicted. Nevertheless, both medications require that the patient's renal functions be monitored during the treatment. Further studies conducted in multiple oncology centres with a larger sample are needed to evaluate the toxicity of paclitaxel and nab-paclitaxel in adult patients with breast and pancreatic cancer.

Over-the-Counter Medication Use among Parents in Saudi Arabia.

Introduction: Self-medication is a growing public health concern worldwide. Studies have shown a gap between best practice and the current practice of using over-the-counter (OTC) medications. Despite being a well-recognised problem in Saudi Arabia, few studies have investigated OTC medication use in Saudi Arabia. Therefore, this study aimed to investigate the attitudes and knowledge of parents regarding OTC medication use in the Jeddah region, Saudi Arabia. Method: A cross-sectional study was carried out via an electronic questionnaire sent randomly to parents over four months, from 1 January to 30 April 2022. The participants' characteristics and categorical variables were represented descriptively by frequency and percentage. A Chi-square test was used to test the relationship between the variables. Results: In total, 211 questionnaires were included in this study. Females represented 54.5% of the participants included in the study. Parents belonging to the 18-to-30-year-old group comprised the highest percentage (37.9%), and most of the parents (72.9%) had received an undergraduate education. Family physicians were the most common source (37.3%) of information about OTC medications, whereas more than half of parents purchased OTC medications from the community pharmacy (58.8%). While almost half of the parents (52.1%) visited a family physician when side effects of OTC medications appeared in their children, only (33.6%) stopped giving their children the OTC medicine. The relationship between the sociodemographic characteristics (including educational level, marital status, and employment status) and OTC drug consumption was significant (p < 0.001). Conclusion: Educational campaigns are needed to guide patients about the proper use of OTC medications. Studies on OTC medication use are lacking in Saudi Arabia in terms of its frequency, reasons for use, type of self-medication, and contributing factors.

Risk of Polypharmacy and Its Outcome in Terms of Drug Interaction in an Elderly Population: A Retrospective Cross-Sectional Study.

The simultaneous use of multiple drugs-termed 'polypharmacy'-is often required to manage multiple physiological and biological changes and the interplay between chronic disorders that are expected to increase in association with ageing. However, by increasing the number of medications consumed, the risk of undesirable medication reactions and drug interactions also increases exponentially. Hence, knowledge of the prevalence of polypharmacy and the risk of potentially serious drug-drug interactions (DDIs) in elderly patients should be considered a key topic of interest for public health and health care professionals. Methods: Prescription and demographic data were collected from the electronic files of patients who were aged ≥ 65 years and attended Al-Noor Hospital in Makkah, Saudi Arabia, between 2015 and 2022. The Lexicomp® electronic DDI-checking platform was used to evaluate the patients' medication regimens for any potential drug interactions. Results: A total of 259 patients were included in the study. The prevalence of polypharmacy among the cohort was 97.2%: 16 (6.2%) had minor polypharmacy, 35 (13.5%) had moderate polypharmacy, and 201 (77.6%) had major polypharmacy. Of the 259 patients who were taking two or more medications simultaneously, 221 (85.3%) had at least one potential DDI (pDDI). The most frequently reported pDDI under category X that should be avoided was the interaction between clopidogrel and esomeprazole and was found in 23 patients (18%). The most frequently reported pDDI under category D that required therapeutic modification was the interaction between enoxaparin and aspirin, which was found in 28 patients (12%). Conclusions: It is often necessary for elderly patients to take several medications simultaneously to manage chronic diseases. Clinicians should distinguish between suitable, appropriate and unsuitable, inappropriate polypharmacy, and this criterion should be closely examined when establishing a therapeutic plan.

Case Reports Study on Methanol Poisoning in King Abdul Aziz Specialist Hospital, Taif, Saudi Arabia.

Methanol poisoning is a challenging issue due to its inducing acute multiple organ failures, and especially due to a lack of preparedness, available antidotes, and management protocols. The current study presents six cases of methanol poisoning that attended the emergency department of King Abdul Aziz Specialist Hospital, Taif, Saudi Arabia, between March and November 2022. All of the patients suffered from severe metabolic acidosis and visual impairment following the ingestion of homemade alcoholic beverages and colonia. Three patients were comatose, suffered from post-cardiac pulmonary arrest, and, finally, died, while the other three were non-comatose and discharged from the ICU after improvement. Management was based on clinical symptoms and other laboratory findings due to a shortage of methanol level measurement resources. The antidote, fomepizole, was not given to all of the cases due to its deficiency, and ethanol was given only to one patient due to difficulties in administering it without monitoring its concentration. Methanol poisoning and its outbreak provide insights into the dangers of hazardous homemade alcohol and other pharmaceutical preparations that might be adulterated with methanol, particularly to the shortage of suitable diagnostic testing and antidotes in addition to poor resources for management of intoxicated patients in some regions of Saudi Arabia.

Polypharmacy among patients with hypertension attending primary healthcare centres.

Saudi Arabia has several hypertensive patients who require close attention and specialised care for their medications. Polypharmacy is one of the reasons for the failure of patient compliance with antihypertensive medications. Therefore, this study aims to gain a better perspective on polypharmacy in hypertensive patients attending primary healthcare (PHC) centres in Makkah, Saudi Arabia. Methods: This was an observational, cross-sectional, descriptive study of hypertensive patients followed up at 10 PHC centres in Makkah, Saudi Arabia, from 1 July 2019 to 30 June 2022. Frequencies and percentages were used to present categorical data, and Pearson's χ 2 test was used to measure differences. A P value less than 0.05 was considered statistically significant. Results: A total of 506 patients were included in this study. The mean age of the patients was 60 years, and more than half (69%) were females. Regarding antihypertensive medication use, 64% were on antihypertensive combination therapy, 76% on dual therapy, 21% on triple therapy, and 3% on quadruple therapy. Moreover, 21% of the hypertensive patients were exposed to polypharmacy. There was a significant relationship (P<0.001) between the overall number of chronic medications used per day and the duration of hypertension. Conclusion: More clinical research is needed to identify the impact of polypharmacy on the quality of healthcare in PHC centres in general and hypertensive patients specifically in different regions of Saudi Arabia.

Perceptions of Saudis Toward Participating in the COVID-19 Convalescent Plasma Clinical Trial.

Introduction The COVID-19 pandemic has been a major public health and economic issue worldwide. Even though vaccines have been developed to reduce the spread of the infection, treating patients remains a significant challenge. This study aims to measure the perceptions of Saudis toward participating in the COVID-19 Convalescent Plasma Clinical Trial. Method A cross-sectional study measuring the perceptions of Saudis toward participating in the COVID-19 Convalescent Plasma Clinical Trial was conducted with participants who had recovered from COVID-19. The study used an online questionnaire covering variables related to demographics, awareness, attitudes, perceptions, and plans for improvement. Results A sample of 1,051 participants participated in the questionnaire. A total of 85% had recovered from COVID-19, only 2.76% had participated in clinical trials before, and 83.44% would participate if they were advised or knew about them. The participants showed a high level of education, with 88% having obtained a degree and most used social media. The results can be biased toward the participants who get their knowledge from social media and hope to learn about things on social media. The gap in knowledge about clinical trials among the participants indicated that certain age groups could be targeted through channels where they communicate the most. Conclusion Engaging the community in clinical trials and educating others about their value by sharing experiences would help promote clinical trials and activate donations.

A New Vision of Teaching Clinical Pharmacology and Therapeutics for Undergraduate Medical Students.

For many years, clinical pharmacology (CP) has been taught at schools of medicine via traditional methods including classic lectures and experimental sessions. The explosion of scientific knowledge and the availability of many treatment options have necessitated the development of new strategies for pharmacology teaching and learning. Applying information learnt in real-life situations has become more important than finding information that is readily available in many places. The newly implemented reformed curriculum at Umm Al Qura University - Faculty of Medicine (UQUMED) is a student-centred, competency-based curriculum with enhanced integration across the disciplines. Teachers and students have a great responsibility in updating the curriculum. The "Use of Medicine" (UofM) vertical module is part of this reformed curriculum that focuses on key principles, a core list of medications, the vertical and horizontal integration of subjects, the knowledge application to real case situations, enhanced critical thinking and self-learning. It emphasizes rational prescribing, safe medical practice and excellence in teaching CP and therapeutics. The adoption of newer and innovative teaching and assessment methods and the training of faculty/staff can help to refresh CP education. One challenge in CP education is that teachers are shifting from acting as information providers to acting as facilitators so that students become life-long learners. The assessment of our reformed curriculum uses several valid reliable tools to evaluate the achieved skills and competencies. This manuscript describes the transformational changes in CP education at UQU up to the development and implementation of the UofM vertical module as part of the reformed UQUMED curriculum. Continuous updates in CP education are critical for rational, safe, and affordable medication prescribing for better patient care.

Efficacy and Safety of Empagliflozin in Type 2 Diabetes Mellitus Saudi Patients as Add-On to Antidiabetic Therapy: A Prospective, Open-Label, Observational Study.

The Saudi Food and Drug Authority (SFDA) approved sodium-glucose cotransporter-2 (SGLT2) inhibitors in 2018. The efficacy and safety of empagliflozin (EMPA) have been confirmed in the U.S., Europe, and Japan for patients with type 2 diabetes mellitus (T2DM); however, analogous evidence is lacking for Saudi T2DM patients. Therefore, the current study aimed to assess the efficacy and safety of EMPA in Saudi patients (n = 256) with T2DM. This is a 12-week prospective, open-label, observational study. Adult Saudi patients with T2DM who had not been treated with EMPA before enrolment were eligible. The exclusion criteria included T2DM patients less than 18 years of age, adults with type one diabetes, pregnant women, paediatric population. The results related to efficacy included a significant decrease in haemoglobin A1c (HbA1c) (adjusted mean difference −0.93% [95% confidence interval (CI) −0.32, −1.54]), significant improvements in fasting plasma glucose (FPG) (−2.28 mmol/L [95% CI −2.81, −1.75]), and a reduction in body weight (−0.874 kg [95% CI −4.36, −6.10]) following the administration of 25 mg of EMPA once daily as an add-on to ongoing antidiabetic therapy after 12 weeks. The primary safety endpoints were the change in the mean blood pressure (BP) values, which indicated significantly reduced systolic and diastolic BP (−3.85 mmHg [95% CI −6.81, −0.88] and −0.06 mmHg [95% CI −0.81, −0.88], respectively) and pulse rate (−1.18 [95% CI −0.79, −3.15]). In addition, kidney function was improved, with a significant reduction in the urine albumin/creatinine ratio (UACR) (−1.76 mg/g [95% CI −1.07, −34.25]) and a significant increase in the estimated glomerular filtration rate (eGFR) (3.54 mL/min/1.73 m2 [95% CI 2.78, 9.87]). Furthermore, EMPA reduced aminotransferases (ALT) in a pattern (reduction in ALT > AST). The adjusted mean difference in the change in ALT was −2.36 U/L [95% CI −1.031, −3.69], while it was −1.26 U/L [95% CI −0.3811, −2.357] for AST and −1.98 U/L [95% CI −0.44, −3.49] for GGT. Moreover, in the EMPA group, serum high-density lipoprotein (HDL) significantly increased (0.29 mmol/L [95% CI 0.74, 0.15]), whereas a nonsignificant increase was seen in low-density lipoprotein (LDL) (0.01 mmol/L [95% CI 0.19, 0.18]) along with a significant reduction in plasma triglyceride (TG) levels (−0.43 mmol/L [95% CI −0.31, −1.17]). Empagliflozin once daily is an efficacious and tolerable strategy for treating Saudi patients with insufficiently controlled T2DM as an add-on to ongoing antidiabetic therapy.

Reported Cases of Alcohol Consumption and Poisoning for the Years 2015 to 2022 in Hail, Saudi Arabia.

This study aimed to determine the pattern of alcohol consumption and its poisoning among the Saudi population in the city of Hail, KSA. Data from a retrospective cohort were collected qualitatively at King Khalid Hospital (KKH) and Hail General Hospital (HGH), covering 550 participants from 2015 to 2022. Two groups were formed comprising patients admitted to the emergency room (ER) and community members; their ages ranged from 19 to 75 years. Group 1 contained 400 participants, of which 250 were patients (244 males, six females) who came to the (ER) with a suspected alcohol overdose or poisoning, and 150 were patients (128 males and 22 females) who were discharged from the (ER) with minimal complaints because of their drinking. Group 2 comprised 150 participants (128 males, 22 females) who were community members, who were surveyed using a questionnaire or interview. In Group 1, 30% of patients reported an altered state of consciousness as a major complaint, 28.8% of patients exhibited abnormal liver function tests (LFTs), 27% had abnormal renal function tests (RFT) with decreased glomerular filtration rates (GFR) and elevated levels of urea and creatinine or low levels of electrolytes or calcium, and 35.6% patients showed elevated levels of pancreatic enzymes. One death was reported due to high alcohol consumption. In Group 2, the community participants reported that they started drinking alcohol due to the influence of other people (29%), stress (11%), depression (10.8%), curiosity (4.4%), and boredom (4%). In addition, 77% of participants were frequent alcohol drinkers and 20% consumed it daily. Further, 68.7% claimed to drink alcohol for more than one hour at a time, while 83.3% experienced blackouts and 70% had problems related to their liver. Moreover, 72.7% of the participants ended up in the hospital and 34.6% suffered from multiple chronic diseases. It is concluded that social influences and stress contributed to the initiation of alcohol use. Despite data gaps, the findings of this study provide a practical understanding of alcohol consumption among the Saudi population and guidance for policymakers.
