Arabic translation and cultural adaptation of Hill-Bone compliance to high blood pressure therapy scale.

Background: Adherence to prescription medications is vital to the success of any treatment plan, especially for chronic health conditions, such as hypertension (HTN). Although there are different scales used in assessing adherence to prescription medications, most if not all, of those scales are not available in Arabic. The absence of essential assessment tools makes the appraisal of adherence to prescription medications very difficult for native Arabic speakers. Therefore, this study aimed to translate and validate the Hill-Bone Compliance to High Blood Pressure Therapy (CHBPT) scale, which is commonly used to assess adherence to antihypertensive medications, among a sample of Arabic-speaking patients with HTN. Methods: This was a single-center cross-sectional study that took place at a university-affiliated hospital. It interviewed adult (≥18 years) patients with HTN who were visiting the primary care clinics between January and November 2020. Non-Arabic speakers, those under 18 years of age, individuals without a diagnosis of HTN, and patients without any previously filled prescription medications for HTN within the past three months were excluded. The forward-backward translation method was used after receiving permission from the originators of the questionnaire to translate their scale to Arabic. Test-retest and Cronbach alpha methods were used to assess the reliability. Principal component analysis with varimax rotation was used to examine the construct validity. Results: One hundred and forty-one patients consented and participated in the study. Most of the patients were ≥ 50 years old (75 %), male (72 %), and had another chronic health condition besides HTN (99 %). The translated scale had good internal consistency (Cronbach alpha = 0.83) and reliability (intraclass correlation coefficient of 0.9). The Kaiser-Meyer-Oklin was 0.82 indicating adequate sampling to conduct factor analysis; hence, three factors (e.g., subscales) were extracted similar to the original scale. The mean scores for appointment keeping, medication taking, and reducing sodium intake subscales, as well as for the overall scale were 5.62 ± 1.39, 33.94 ± 3.87, 9.73 ± 2.1, and 49.29 ± 5.21, respectively. Conclusion: The translated version of the Hill-Bone CHBPT scale has both good reliability and validity and will hopefully help healthcare providers assess and monitor HTN patients' adherence to their antihypertensive medication regimens. Multicenter studies should be conducted to verify the validity and reliability of the translated questionnaire among different Arabic-speaking patient populations with HTN.

Cost consequence analysis of adding semaglutide to treatment regimen for patients with Type II diabetes in Saudi Arabia.

Introduction: Semaglutide, a Glucagon-like Peptide-1 Receptor Agonist (GLP-1 RA), is often prescribed for managing type 2 diabetes, particularly in cases unresponsive to other hypoglycemic agents. Despite its popularity, the real-world efficacy and cost-effectiveness of Semaglutide relative to other treatments remain understudied. Objective: This study aimed to examine the direct medical cost and consequences of adding Semaglutide to the treatment regimen for patients with type 2 diabetes in Saudi Arabia. Methods: We conducted a single-center, retrospective review of Electronic Medical Records (EMRs) for adults with type 2 diabetes. Patients who had been on Semaglutide for at least three months were matched with those receiving alternative hypoglycemic therapies. Exclusions were made for patients with cancer, incomplete EMRs, or lacking prescription data. Investigated outcomes included changes in HbA1C levels and weight, and the direct costs comprised medications, clinic visits, and emergency care. Baseline adjustments were made through inverse probability treatment weighting, and uncertainty was assessed via bootstrapping with 10,000 replications. Results: Out of 350 patients meeting the criteria, 116 were on Semaglutide. Predominantly females (62%), the cohort had an average age of 60 and a disease duration of 22 years. The difference in HbA1C (%) reductions between Semaglutide and non-Semaglutide users over 3,6, and 12 months were 0.154 (95% CI: -0.452-0.483), -0.031(95% CI: -0.754-0.239), -0.16(95% CI: -1.425-0.840), respectively. Semaglutide users did experience modest weight reductions ranging from 0.42 kg to 1.16 kg. The annual additional direct medical cost for Semaglutide was USD 4,086.82 (95% CI: $3,710.85 - $4,294.99). Conclusion: Although Semaglutide induced modest weight reductions, it did not offer significant advantages in lowering HbA1C levels compared to other hypoglycemic treatments. These findings suggest the need for further research involving larger and more diverse cohorts to corroborate these findings.

Valuation of EQ-5D-5L in the Kingdom of Saudi Arabia: A National Representative Study.

OBJECTIVES: To estimate a Saudi-specific value set for the EQ-5D-5L questionnaire using the EuroQol Valuation Technology program and the EuroQol Group's standard protocol. METHODS: Participants were quota-sampled from the Saudi adult population based on residency location, age group, gender, education level, and employment status. The participants were guided through the completion of composite time trade-off (cTTO) and discrete choice experiment (DCE) tasks by trained interviewers using EuroQol Valuation Technology software. Quality control (QC) measures were used to ensure good data quality. Random intercept and Tobit models analyzed the cTTO data, as well as models correcting for heteroskedasticity. DCE data were analyzed using conditional logit models, whereas hybrid models were used to analyze the cTTO and DCE data jointly. To evaluate model performance, prediction accuracy, logical consistency, significance level, and goodness of fit were used. RESULTS: The valuation study included a representative sample of the Saudi population (N = 1000). The hybrid heteroskedastic model without a constant was chosen as the preferred model for generating the value set. The predicted values ranged from -0.683 for the worst health state ("55555") to 1 for the full health state ("11111"). Pain and discomfort had the largest impact on health-state preference values, whereas usual activities had the least. CONCLUSION: The value set for the Kingdom of Saudi Arabia is the first value set for the EQ-5D-5L for any country in the Middle East. The value set can be used in Saudi health system economic evaluations and decision making.

The socioeconomic burden of spinal muscular atrophy in Saudi Arabia: a cross-sectional pilot study.

Background: Spinal muscular atrophy (SMA) is a rare debilitating condition with a significant burden for patients and society. However, little is known about how it affects Saudi Arabia's population. The socioeconomic and medical characteristics of affected SMA patients and their caregivers are lacking. Purpose: This study aimed to describe the socioeconomic and medical characteristics of SMA patients and caregivers in Saudi Arabia. Patients and methods: A cross-sectional questionnaire-based study was conducted using snowball sampling. Assessment tools including EuroQol (EQ-5D-5L) and visual analog scale (EQ-VAS), Generalized Anxiety Disorder 7-item (GAD-7), Patient Health Questionnaire (PHQ-9), and Costs for Patients Questionnaire (CoPaQ) were used to assess the quality of life (QoL), anxiety, depression, and out-of-pocket expenditures. Results: Sixty-four caregivers of SMA patients participated. Type I patients had higher sibling concordance, ICU hospitalization, and mechanical support needs. Type III patients had better QoL. Type I patients' caregivers had higher depression scores. Type III patients' caregivers had higher out-of-pocket expenditures. Forty-eight percent received supportive care, while others received SMA approved therapies. Conclusion: SMA imposes a significant socioeconomic burden on patients and caregivers, requiring more attention from the healthcare system. Access to innovative therapies varied across SMA types. Pre-marital screening and early detection are crucial to reduce disease incidence and ensure timely treatment.

Cost-consequence analysis of tocilizumab versus adalimumab and etanercept among rheumatoid arthritis patients in Saudi Arabia: a single-center study.

BACKGROUND: The study aimed to examine the direct medical cost and impact of tocilizumab (TOZ) versus adalimumab (ADM) and etanercept (ETC) on reducing the levels of two inflammatory markers (e.g., C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR)) among patients with rheumatoid arthritis (RA) using real-world data from Saudi Arabia. METHOD: This was a single-center retrospective cohort study in which data for biologic-naïve RA patients aged ≥ 18 years and treated with TOZ, ADM, ETC were retrieved from the electronic medical records (EMRs) of a university-affiliated tertiary care center in Riyadh, Saudi Arabia. Patients were followed up at least one year after the treatment initiation. Bottom-up microcosting was utilized to estimate the direct medical costs. Additionally, inverse probability treatment weighting and bootstrapping with 10,000 replications were conducted to generate 95% confidence levels for costs and the mean reductions in CRP and ESR levels. RESULTS: The number of patients who met the inclusion criteria and were included in the analysis was 150 patients (TOZ (n = 56), ADM (n = 41), ETC (n = 53)). Patients on TOZ had 3.96 mg/L (95% CI: -0.229-4.95) and 11.21 mm/hr (95% CI: 10.28-18.11) higher mean reductions in the CRP and ESR levels compared to their counterparts on ADM, ETC, respectively. However, this was associated with mean annual incremental costs of USD 10,087.88 (95% CI: 9494.50-11,441.63) in all cost-effectiveness bootstrap distributions. CONCLUSION: Tocilizumab has shown better effectiveness in reducing the levels of CRP and ESR but with higher costs. Future studies should examine whether the reduction of these two inflammatory markers is associated with quality-adjusted life years (QALYs) gains.

Cost-Consequence Analysis of Colon Cancer Screening among Patients with Long-Standing Ulcerative Colitis: 11 Years' Experience of Saudi Population.

Background: Clinical guidelines recommend that patients with long-standing ulcerative colitis (UC) should undergo periodic surveillance colonoscopy. However, the cost and clinical value of performing annual colonoscopy among high-risk patient populations is largely unknown in the Middle East. Therefore, this study aimed to examine the cost and consequence of annual colonoscopy among high-risk UC patients in Saudi Arabia. Methods: A retrospective cohort study was conducted on UC patients who had UC for ≥ 8 years or had primary sclerosing cholangitis (PSC) at any time during their disease,and underwent colonoscopy surveillance between 2010 and 2021 at a university-affiliated tertiary care center. Patients who underwent annual screening were considered adherent, and those who did not were considered non-adherent. The dysplasia detection rate (%) and the costs were expressed in United States Dollars (USD). To generate the 95 % confidence intervals for annual cost and clinical consequence, nonparametric bias-corrected accelerated bootstrapping with 10,000 simulations were conducted. Results: Two-hundred and sixty-one UC patients met the inclusion criteria and were included. Most of the patients 54 % (141 patients), were non-adherent to annual screening, and the patients' mean age and duration of illness were 45 years and 15 years, respectively. The mean annual direct medical costs were USD 10,210.6 for patients who adhered to the annual screening program and USD 6,191.77 for those who did not adhere. The mean rates of dysplasia detection were 1.66 % and 7.09 % for patients who adhered and patients who did not adhere to annual colonoscopy, respectively. The difference in costs and rates of dysplasia detections between those who adhered to the annual screening and those who did not were USD 4,018.88 (95 % CI: 3097.46 - 6,798.06) and -5.43 % (95 % CI: -10.019 - -1.58730), respectively, resulting in an incremental cost-effectiveness ratio (ICER) of USD 740.125 per 1 % reduction in the rates of dysplasia. According to the bootstrap cost effectiveness distributions, adherence to the annual screening for UC patients would result in higher cost and lower rates of dysplasia development with more than 99 % confidence level. Conclusion: Adherence to annual colonoscopy screening detects more dysplasia in UC patients but with an increased cost. Considering the low rate of progression to colorectal cancer among UC patients, the annual screening might not be cost effective.

Comparative effectiveness and cost evaluation of Risankizumab and Adalimumab in the management of psoriasis: a real-world study in Saudi Arabia.

BACKGROUND: Psoriasis, an immune-mediated chronic inflammatory disease primarily affecting skin and joints, has varying prevalence rates globally. It manifests in five types, with chronic plaque psoriasis being the most common. Treatment, which has no definitive cure, aims for complete resolution of skin symptoms and depends on disease extent, severity, and impact on patients' lives. Biologics are an emerging treatment for psoriasis, targeting specific inflammatory pathways for potentially safer, more effective outcomes. However, these come with significant costs, necessitating more research to ensure value for money. This study aimed to compare the effectiveness of Risankizumab versus Adalimumab, the most commonly utilized biologic for managing psoriasis in Saudi Arabia. METHODS: This study retrospectively compared the effectiveness and direct medical cost of Risankizumab and Adalimumab in treating chronic plaque psoriasis in adults from two Saudi Arabian healthcare centers. The Psoriasis Area and Severity Index (PASI) and body surface area (BSA) were used to assess treatment effectiveness, with patient data sourced from electronic medical records. Multiple regression analysis was performed to examine various factors affecting treatment outcomes. An economic evaluation was conducted to examine the cost-effectiveness of the two drugs, considering four scenarios with varying dosage patterns and costs. Analysis was performed from the perspective of public healthcare payers and considered all utilized health services. RESULTS: The data for 70 patients were analyzed, with comparable baseline characteristics between groups. While Risankizumab led to a greater reduction in PASI scores and BSA affected, these results were not statistically significant. The annual treatment cost for Risankizumab was higher than Adalimumab. Various scenarios were studied, considering real acquisition costs, double dosing for Adalimumab, and the use of biosimilars. A scenario assuming double dosing for Adalimumab and a 40% discount for Risankizumab demonstrated both cost and efficacy advantages in 71.25% of cases. CONCLUSIONS: This study compared the effectiveness and cost of Risankizumab and Adalimumab for treating chronic plaque psoriasis in Saudi Arabian hospitals. Although Risankizumab showed a greater reduction in symptoms, the difference was not statistically significant. However, under certain scenarios, Risankizumab demonstrated cost and efficacy advantages. These findings may influence treatment decisions for psoriasis, but further research is needed.

Anxiety and depression and health-related quality of life among adults with migraine: a National Population-Based Study.

Background: Adults who suffer from migraines are highly susceptible to mental illnesses that may have significant association with their HRQoL. Therefore, this study aimed to investigate how anxiety and depression related to HRQoL in adults with Migraine. Methods: Data from the Medical Expenditure Panel Survey for 2017 to 2020 were used to identify adult patients 18 years of age and older with a migraine diagnosis. The Physical and Mental Component Summary (PCS & MCS) scores from the SF-12 were used to calculate HRQoL. To adjust for a wide range of variables, multivariate linear regressions were used to evaluate the association between depression and anxiety and HRQoL among adults with migraine. Results: Among the 1,713 identified adults with migraines, 11.2% experienced depression, 14.6% experienced anxiety, and 13.7% had both conditions. Compared to migraineurs who had only migraine, adults with comorbid depression and anxiety had the lowest mean scores on the PCS and MCS. Additionally, migraineurs who had depression had significantly lower HRQoL MCS scores (depression: ß = -7.552, p < 0.001), and those with anxiety had significantly lower HRQoL MCS scores (anxiety: ß = -4.844, p < 0.001) compared to those without these comorbidities. Notably, individuals with migraines who exercise had higher scores on both PCS and MCS than those who did not exercise. Conclusion: This nationally representative sample provides insights into the associations between depression and anxiety with poor HRQoL among individuals with migraines. Additionally, it revealed the negative impact of concurrent chronic diseases, and poor socioeconomic status on HRQoL, while emphasizing the beneficial effects of regular exercise. This study highlights the clinical, policy, and public health implications for improving healthcare planning, resource allocation, and promoting lifestyle changes to reduce depression and anxiety in migraine sufferers.

Local causes of essential medicines shortages from the perspective of supply chain professionals in Saudi Arabia.

Background: The global supply chains of essential medicines faced frequent disruptions over the past five years, particularly during the COVID-19 pandemic. Different causes of prescription drug supply interruptions have been identified in Saudi Arabia. However, studies have yet to explore the views of pharmaceutical supply chain personnel regarding the causes of these interruptions. Therefore, this study aimed to survey individuals working in the pharmaceutical supply chains about their views on the observed interruptions in the supply of some essential drugs. Methods: This was a questionnaire-based cross-sectional study. The 10-item questionnaire was created based on the findings of previously published research that investigated the root causes of essential drug shortages and the impact of COVID-19 pandemic on the supply chains of essential drugs in Saudi Arabia. Purposive sampling was used to identify individuals with at least one year of experience in the area of the pharmaceutical supply chain, and the data collection occurred between April 19th, 2022 and October 23rd, 2022. In addition, descriptive statistics (e.g., frequencies and percentages) were conducted to present the views of the respondents. Results: Seventy-nine pharmaceutical supply chain specialists accepted the invitation and completed the questionnaire. About two-thirds (69.62%) of the respondents reported that centralized pharmaceutical procurement negatively affected the supply chain of essential drugs. Procurement of unregistered medications by the Saudi Food and Drug Authority (SFDA), as well as generic drugs with a history of recalls, and failure to supply requested quantities were the three most commonly reported reasons behind the observed interruptions in the supply of some essential drugs according to those respondents with a negative view of the centralized procurement. Furthermore, failure of pharmaceutical companies to inform SFDA of potential drug shortages, manufacturing issues, poor demand forecasting, unpredictable increase in demand, and low prices of essential drugs were also believed to be behind the observed interruptions in the supply of some essential medicines. Conclusion: The majority of surveyed pharmaceutical supply chain professionals held negative views about the role of centralized pharmaceutical procurement in exacerbating the issues with essential medicines supply chain. Future research should examine different strategies to improve purchasing and procurement practices in Saudi Arabia.

Clinical and economic evaluations of natalizumab, rituximab, and ocrelizumab for the management of relapsing-remitting multiple sclerosis in Saudi Arabia.

INTRODUCTION: The advent of new disease-modifying therapies (DMTs), such as monoclonal antibodies (mAbs), resulted in significant changes in the treatment guidelines for Multiple sclerosis (MS) and improvement in the clinical outcomes. However, mAbs, such as rituximab, natalizumab, and ocrelizumab, are expensive with variable effectiveness rates. Thus, the present study aimed to compare the direct medical cost and consequences (e.g., clinical relapse, disability progression, and new MRI lesions) between rituximab and natalizumab in managing relapsing-remitting multiple sclerosis (RRMS) in Saudi Arabia. Also, the study aimed to explore the cost and consequence of ocrelizumab in managing RRMS as a second-choice treatment. METHODS: The electronic medical records (EMRs) of patients with RRMS were retrospectively reviewed to retrieve the patients' baseline characteristics and disease progression from two tertiary care centers in Riyadh, Saudi Arabia. Biologic-naïve patients treated with rituximab or natalizumab or those switched to ocrelizumab and treated for at least six months were included in the study. The effectiveness rate was defined as no evidence of disease activity (NEDA-3) (i.e., absence of new T2 or T1 gadolinium (Gd) lesions as demonstrated by the Magnetic Resonance Imaging (MRI), disability progression, and clinical relapses), while the direct medical costs were estimated based on the utilization of healthcare resources. In addition, bootstrapping with 10,000 replications and inverse probability weighting based on propensity score were conducted. RESULTS: Ninety-three patients met the inclusion criteria and were included in the analysis (natalizumab (n = 50), rituximab (n = 26), ocrelizumab (n = 17)). Most of the patients were otherwise healthy (81.72%), under 35 years of age (76.34%), females (61.29%), and on the same mAb for more than one year (83.87%). The mean effectiveness rates for natalizumab, rituximab, and ocrelizumab were 72.00%, 76.92%, and 58.83%, respectively. Natalizumab mean incremental cost compared to rituximab was $35,383 (95% CI: $25,401.09- $49,717.92), and its mean effectiveness rate was 4.92% lower than rituximab (95% CI: -30-27.5) with 59.41% confidence level that rituximab will be dominant. CONCLUSIONS: Rituximab seems to be more effective and is less costly than natalizumab in the management of RRMS. Ocrelizumab does not seem to slow the rates of disease progression among patients previously treated with natalizumab.

The characteristics and distribution of emergency medical services in Saudi Arabia.

BACKGROUND: Emergency medical services (EMS) play an essential role in treating and transporting patients to hospitals or between hospitals. EMS providers must be distributed wisely across all regions of the country to meet healthcare needs during normal times and disasters. No previous study has investigated the characteristics and distribution of the EMS workforce in Saudi Arabia. OBJECTIVES: Examine the characteristics and distribution of the EMS workforce in Saudi Arabia to identify gaps and areas in need of improvement. Also, explore the sociodemographic and educational characteristics of licensed EMS providers in Saudi Arabia. DESIGN: Cross-sectional SETTINGS: EMS in Saudi Arabia METHODS: We included all licensed EMS providers in Saudi Arabia as of 23 December 2020 who were registered in the Saudi Commission for Health Specialties (SCFHS) database. Sociodemographics, where they earned certification, and their job affiliations were collected and categorized. MAIN OUTCOME MEASURES: EMS workforce distribution, gender, and EMS provider-to-population ratio. SAMPLE SIZE: 18 336 EMS providers; 8812 (48.1%) with documented job affiliations. RESULTS: The EMS provider-to-population ratio is very low. In Saudi Arabia, in general, the ratio is 1:3871 (based on n=8812 providers), which is low compared to the 1:1400 ratio for Australian EMS provider-to-population, for example. That makes it a challenge for EMS providers to meet the population's needs, especially in times of disaster. The low ratio may have contributed to the delayed response time in Saudi Arabia (13 minutes for critical cases) which does not meet the international standard response time (8 minutes maximum). Also, only 3.5% of the total EMS providers registered were females, and the clear majority of all EMS providers were technicians. CONCLUSIONS: The growth in the EMS workforce, including the recruitment of more females into the workforce and more EMS specialists compared to EMS technicians and health assistants, is critical to reaching a satisfactory EMS provider-to-population ratio. LIMITATIONS: Most noteworthy of the limitations of this research are the insufficient statistics describing EMS distribution in Saudi Arabia, the lack of previous studies on the research topic in Saudi Arabia, and job affiliation not accurately recorded in the SCFHS database. CONFLICT OF INTEREST: None.

Self-medication among adults with chronic health conditions: a population-based cross-sectional survey in Saudi Arabia.

OBJECTIVES: This study aimed to assess the prevalence of self-medication (SM), the reasons for SM and the relationship between chronic health conditions and SM among adult individuals. SETTING: This was an online questionnaire-based cross-sectional study disseminated on different social media platforms in Saudi Arabia. PARTICIPANTS: Saudi Arabia sample of adult individuals aged 18 and above. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcome was SM, measured using the following question: 'During the past 6 months, have you used any medicines or dietary supplements, or herbal medicines or vitamins not prescribed or recommended by a doctor?' A positive answer indicates a self-medicated participant. RESULTS: Out of 1645 individuals who viewed the study link, 1295 participants completed the survey with a response rate of 95.1%. Overall, 989 (76.4%) participants reported practicing SM in the past 6 months. SM was higher among younger participants, women, those with higher education levels and high income, and working in the health field. About 198 (73.3%) who have chronic conditions practised SM for chronic health conditions, such as (hypertension and hypercholesterolemia). Previous experience with the same illness (n=530, 25.7%) and attempting to save time (n=466, 22.6%) were the main reasons behind SM, according to the participants. Adverse drug events were reported by 204 (20.6%) of self-medicating individuals and 274 (64.9%) of them reported discontinuing SM. CONCLUSIONS: The findings of this study indicate a high prevalence rate of SM among the adult population in Saudi Arabia. Individuals with chronic health conditions reported a high rate of SM. Launching public education campaigns to improve public awareness of the harms of SM if misused, especially among those with chronic health conditions, is essential.

The Impact of Depression and Anxiety on Adult Cancer Patients' Health-Related Quality of Life.

BACKGROUND: Cancer patients are at high risk for mental illness and, in turn, poorer health-related quality of life. This study used nationally representative United States (US) data to examine nuances of the impact of depression and/or anxiety on HRQoL in different cancer groups (e.g., cancer only, cancer and depression, cancer and anxiety, cancer and both conditions). METHODS: Adult patients aged 18 years and older with a cancer diagnosis were identified from the Medical Expenditure Panel Survey data for 2012-2016. HRQoL was measured using the SF-12 Physical and Mental Component Summary (PCS & MCS) scores. Multivariate linear regressions were used, controlling for a multitude of factors. RESULTS: Around 12% of the 1712 identified patients with cancer had depression, 13% had anxiety, and 8.4% had both depression and anxiety. Patients with comorbid depression and anxiety had the lowest mean scores of both PCS and MCS compared to patients in other groups. In addition, cancer patients with either depression and/or anxiety were more likely to have lower MCS scores compared to those with cancer only (depression: ß = -6.554; anxiety: ß = -3.916; both conditions: ß = -11.759, p < 0.001). Interestingly, patients with comorbid depression and anxiety were more likely to have higher PCS scores compared to those with cancer only. CONCLUSIONS: The psychological burden of cancer is immense, with a substantial impact on patients' HRQoL. Routine screening for depression and anxiety, especially for women and those with low poverty status and comorbidities, should be conducted by healthcare providers to identify those with high odds of having a lower HRQoL. Additionally, early psychiatric interventions, such as psychotherapy and prescription drugs, may positively impact patients' mental well-being and HRQoL.

Cost Consequence Analysis of Belimumab versus Standard of Care for the Management of Systemic Lupus Erythematosus in Saudi Arabia: A Retrospective Cohort Study.

BACKGROUND: Belimumab use for the management of systemic lupus erythematosus (SLE) has been limited, in part due to its high acquisition cost relative to the standard of care (SoC) and the uncertainties about its cost-effectiveness. Therefore, the aim of this study was to compare the cost and effectiveness of belimumab versus the SoC alone for the management of SLE using real-world data from the perspective of public healthcare payers in Saudi Arabia. METHODS: Data were retrieved from a national prospective cohort of SLE, Saudi Arabia. Adult SLE patients (≥18 yrs.) treated with belimumab plus the SoC or the SoC alone for at least six months were recruited. The effectiveness was measured using the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K). Unit costs for health services and prescription drugs were retrieved from the Saudi ministry of health. Nonparametric bootstrapping with inverse probability weighting was conducted to generate the 95% confidence limits for the cost and effectiveness. RESULTS: A total of 15 patients on belimumab plus the SoC and 41 patients on the SoC alone met the inclusion criteria and were included in the analysis. The majority of patients were females (91.07%) with a mean age of 38 years. The mean difference in cost and SLEDAI-2K score reduction between belimumab versus the SoC were USD 5303.16 [95% CI: USD 2735.61-USD 7802.52] and 3.378 [95% CI: 1.769-6.831], respectively. Belimumab demonstrated better effectiveness but higher cost in 96% of the bootstrap cost-effectiveness distributions. CONCLUSION: Future studies should use more robust research designs and a larger sample size to confirm the findings of this study.

Cost effectiveness of rivaroxaban versus warfarin among nonvalvular atrial fibrillation patients in Saudi Arabia: A Single-Center retrospective cohort study.

Background: Rivaroxaban is a novel oral anticoagulant (NOAC) that is commonly used for stroke prevention among patients with atrial fibrillation (AF). However, its cost effectiveness in reducing the risk of hospitalization and mortality in comparison to warfarin among nonvalvular AF patients in Saudi Arabia is largely unknown. Methods: This was a single-center retrospective chart review of adult patients (≥18 years) with nonvalvular AF who were treated with warfarin or rivaroxaban for at least 12 months. Patients with mitral valve stenosis were excluded from the study. Multiple logistic regression was conducted to examine the risk of hospitalization and mortality as a composite outcome, and all annual healthcare costs were captured. Inverse probability treatment weighting with bootstrapping was conducted to determine the mean costs and effectiveness rates. Results: Two-hundred and twenty-six patients (142 on rivaroxaban and 84 on warfarin) met the inclusion criteria and were included in the analysis. Most of the patients were females (65.91 %), had diabetes (50.57 %) and hypertension (73.76 %), and with a mean age of 68.95 ± 12.55 years. No significant difference in the odds of the composite outcome for rivaroxaban versus warfarin was found (OR = 0.785, 95 % CI = [0.427-1.446], p = 0.443). Rivaroxaban resulted in a mean annual cost saving of $13,260.79 with an 87.65 % confidence level that it would be more effective than warfarin with a mean difference in effectiveness rate of 0.168 % (95 % CI [-5.210-18.36]). Conclusion: Rivaroxaban was associated with lower direct medical costs and non-inferior effectiveness among nonvalvular AF patients in comparison to warfarin.

Exploring the opportunities and challenges to implementing interprofessional education in Saudi Arabia: a qualitative study among faculty.

Interprofessional education (IPE) has potential benefits for improving the quality of patient care, but its implementation is challenged with multiple barriers. The primary objectives of this study were to explore the challenges, benefits, and incentives to establishing IPE from the perspective of healthcare faculty at King Saud University. Forty-five faculty members attended six focus groups, each consisting of 6-8 faculty members representing the five colleges. The focus group interview guide included the benefits of and barriers to establishing IPE in this academic institution, curricular design, and the feasibility of support from the colleges and University administration. A SWOC (Strengths, Weaknesses, Opportunities, Challenges) frame work was utilized to guide the focus group discussions, and the data were analyzed inductively using thematic analysis. Three main themes emerged and were related to (i) barriers, (ii) benefits, (iii) opportunities to facilitate the introduction of IPE, and (iv) suggestions on how to implement IPE and overcome challenges to establish an IPE curriculum. Participants were generally supportive of IPE and aware of the constraints that might impede its implementation. Moreover, they identified potential barriers and incentives to promote IPE. Although participants appreciated the long-term benefits of IPE, creating a supportive environment will require the involvement of the academic community, including students, faculty members, and the University's top management.

Overview of Procurement and Reimbursement of Pharmaceuticals in Saudi Arabia, United Arab Emirates, Qatar, and Egypt: Challenges and Opportunities.

Introduction: There is an increased interest in cost consciousness concerning healthcare spending worldwide. In the Arab world, a major transformation is underway in the healthcare sectors to achieve national and government visions to attain better outcomes with optimal value. This article contains expert recommendations on how decision-makers can implement pharmacoeconomic principles at a national level in the Arab world. Methods: A multidisciplinary panel of experts was formed of policymakers, clinical pharmacists, health economists, and chronic disease control and public health experts from different countries and healthcare sectors. The panel developed consensus recommendations for different stakeholders using a framework analysis method. Results: The experts discussed the limitations and opportunities of implementing the pharmacoeconomics concept in evaluating new technologies in their respective countries. Common limitations recognized in the included countries were a lack of infrastructure to support the adoption of the concept in practice, challenges in obtaining data to support the decision-making process, and the lack of human resources to raise awareness among decision-makers and the public to use health economics in making informed decisions in reimbursing new technologies. Conclusion: The expert panel recommendations will guide relevant stakeholders at a national level per country. Adapting these recommendations to each setting is essential to accommodate the situation and needs of each country.

Health-related quality of life of patients with rheumatoid arthritis on tocilizumab, adalimumab, and etanercept in Saudi Arabia: a single-center cross-sectional study.

Purpose: The aim of this study was to assess the quality of life (QOL) of patients with rheumatoid arthritis (RA) on tocilizumab versus other commonly used monoclonal antibodies (mAbs) (e.g., adalimumab and etanercept). Methods: This was an interview-based cross-sectional study. Adult RA patients (≥18 years) with a disease duration of at least 1 year were included in the study. The Arabic version of EUROQOL (EQ-5D-5L) was used to assess the QOL of RA patients on mAbs. Multiple linear regression was conducted to examine the impact of tocilizumab versus other mAbs on the visual analog scale (VAS) score controlling for age, disease duration, treatment duration, gender, number of comorbidities, and the use of steroids. Results: The number of patients who met the inclusion criteria and consented to be interviewed was 105 patients (tocilizumab (n = 37), adalimumab (n = 31), and etanercept (n = 37)). No significant differences in the scores of the five EQ-5D-5L domains across different mAbs was found. Although the VAS score of patients on tocilizumab was numerically higher compared to their counterparts on adalimumab or etanercept (69.19 vs. 62.79) this was not statistically significant controlling for age, gender, disease and treatment durations, number of comorbidities, and the utilization of steroids (ß = 4.26, 95% CI: [-8.84-17.36], p = 0.52). Conclusion: The use of tocilizumab did not seem to result in better QOL among RA patients. Future studies with larger sample sizes and more robust designs should be conducted to confirm or refute these findings.

The impact of Hydroxyurea on the rates of Vaso-occlusive crises in patients with sickle cell disease in Saudi Arabia: a single-center study.

BACKGROUND: Vaso-occlusive crises (VOCs) are acute and common painful complication of sickle cell disease (SCD), and are the main reason behind the frequent emergency department visits among SCD patients. Hydroxyurea (HU) is an old and commonly used medication that demonstrated its effectiveness in reducing the risk of VOCs and the incidence of hospitalization. Although multiple studies have examined the impact of HU on the rates of VOCs, few have explored its effectiveness among SCD patients in Saudi Arabia. METHODS: This was a single-center retrospective cohort study in which the electronic medical records of patients with SCD who have not had any previous exposure to HU prior to the initiation of HU treatment for ≥12 months were recruited. Paired t-test was conducted to examine the difference in the rates of VOCs, and levels of hemoglobin (Hgb), hematocrit (HCT), and platelet counts (PLT Ct) prior to the initiation of HU therapy and 12 months later. Multiple linear regression was conducted to examine whether age, gender, use of opioid analgesics, Hgb, HCT, and PLT Ct levels predict higher or lower rates of VOCs. RESULTS: One hundred and fifty-six patients met the inclusion criteria and were included in the analysis. About 51% of the patients were males, and their mean age was 12.69 years. The mean HU dosage was 16.52 mg/kg/day, and the mean reduction in the rate of VOCs was 1.36 events per patient per year (95% CI [1.03-1.70], p < 0.0001) after the initiation of HU. Females were more likely to have greater reduction in the rates of VOCs in comparison to their male counterparts (ß-estimate = 12.85, 95% CI [0.759-24.93], p = 0.0374). CONCLUSION: The use of HU results in a significant reduction in the rates of VOCs and emergency department visits. Future studies with robust research designs should be conducted to further examine the impact of HU on VOCs, hospitalization, and length of stay as well as compare HU to other newly approved medications for SCD, such as crizanlizumab.

The long-term growth, cost-effectiveness, and glycemic effects of growth hormone therapy on children born small for gestational age over 10 years: a retrospective cohort study.

OBJECTIVES: We aimed to report our 10-year experience of treating short children born small for gestational age (SGA) by comparing the long-term growth, metabolic safety, and cost-effectiveness of recombinant human growth hormone (rhGH) therapy in short children born SGA with those in rhGH-treated children with growth hormone deficiency (GHD) and Turner syndrome. METHODS: We performed a 10-year retrospective cohort study at King Saud University Medical City. We included children aged 3-16 years who received rhGH for GHD, SGA, or Turner syndrome for >1 year. RESULTS: A total of 166 children received rhGH therapy for GHD, 58 for SGA, and 16 for Turner syndrome. During the last study visit, the average height change was 21 cm for GHD children and 14 cm for children born SGA (p-value <0.001). The height SDS change was 0.84 for GHD children and 0.55 for SGA children (p-value=0.004). The average cost-effectiveness ratios for treating GHD and SGA children were USD 1,717.22 and USD 1,157.19 per centimeter gained, respectively. Moreover, the mean incremental cost-effectiveness ratio for GHD vs. SGA patients was USD 2,820.39 per centimeter gained. Dysglycemia developed in 70 patients: 43 (36.44%), 22 (40.74%), and 5 (13%) in the GHD, SGA, and Turner syndrome groups, respectively. CONCLUSIONS: rhGH is effective in height improvement of short children. However, pursuing rhGH treatment for children born SGA requires a shared decision-making approach to balance the modest benefit of final adult height gain with the long-term metabolic effects, considering the acceptable costs on the Saudi healthcare system.
