Caries prevalence among children at public and private primary schools in Riyadh: a retrospective study.

Dental caries is a global oral health issue, especially critical in children, affecting their growth, nutrition, and education due to school absences or distractions from dental pain. The aim of the study was to investigate the correlation between school types (indicative of socioeconomic conditions) and dental caries prevalence among primary school children in Riyadh, alongside assessing the overall caries prevalence among schoolchildren in Riyadh. Retrospective study on 28,343 first and fourth-grade students from 960 public and private schools in Riyadh, using data from the Saudi Ministry of Health (Feb-April 2019). Utilized the DMFT/dmft index for assessment and collected demographic data. Most of the schools were public (76.1%), private national (17.1%), and private international (6.8%). Overall, the mean DMFT index for permanent teeth and the dmft index for primary teeth were 1.78 and 1.94, respectively. 58% of school children had no dental caries, 25% had mild caries, and 17% had moderate to severe caries. Public school children showed a higher caries prevalence than private schools. Oral disease rates were higher in girls than in boys, and grade four students had a higher prevalence than grade one students. Saudi Arabia, a developing nation, faces challenges in addressing oral health, especially in public schools. Targeted initiatives are crucial for awareness, preventive measures, and meeting oral health needs.

Enhancing Patient Safety: A Cross-Sectional Study to Assess Medical Interns' Attitude and Knowledge About Medication Safety in Saudi Arabia.

Introduction and aim Medication errors (MEs) pose a severe threat in the medical field. Since such errors are preventable, it is paramount for all healthcare workers to be educated on the matter. This study aimed to assess medical interns' attitudes and knowledge of medication safety and errors. We also aimed to validate current university programs to educate students about medication safety and errors. Methods A cross-sectional study that utilized a self-administered online questionnaire comprised 31 questions. The questionnaire was distributed via social media networks, such as WhatsApp, Twitter, email, Instagram, and Snapchat among 100 medical, pharmacy, and nursing interns in Saudi Arabia. The study population included both Saudi and non-Saudi interns. Results The majority of participants, comprising 92% (n=92), indicated that they were familiar with the definition of medication errors (ME). Additionally, 85% (n=85) expressed their willingness to report instances of MEs when medications were not prescribed but required. Moreover, 90% (n=90) of the surveyed individuals expressed their willingness to report MEs in situations where patients did not receive medications as prescribed. In cases where patients experienced harm and required treatment due to an ME, 91% (n=91) of respondents committed to reporting such incidents. A total of 52 (52%) respondents stated that they would report MEs regardless of whether they reached/harmed the patient. A good ME knowledge level was observed in 48% of respondents. A higher likelihood of good ME knowledge was significantly associated with safety reporting system (SRS) awareness and reporting MEs regardless of whether they reached/harmed the patient (p<0.05). College, awareness/attitude, or other demographic factors were not significantly related to ME knowledge (p>0.05). Conclusion This study showed that although interns in the healthcare field do have some knowledge about MEs, there is still a significant need to improve their knowledge. This can be achieved through various ways, one of which is by implementing this topic into the university curricula.

A highlight on carbamazepine-induced adverse drug reactions in Saudi Arabia: a retrospective medical records-based study.

The link between human leukocyte antigen (HLA) alleles and carbamazepine-induced cutaneous, respiratory, and gastrointestinal adverse drug reactions (ADR) has created a window of opportunity for preventing certain forms of cutaneous adverse drug reactions (cADRs); however, there is not enough data to make pharmacogenomic recommendations that can be implemented globally. The aim of this study is to assess and document carbamazepine-induced adverse reactions among prescribed Saudi/non-Saudi patients. A retrospective chart review was performed for patients who received carbamazepine (CBZ) in the period between 2016 and 2020, in the Kingdom of Saudi Arabia. Data were gathered and descriptive statistical analyses were performed on the data for the study sample. Comparisons were made using the chi-square test or independent samples' t-test. Statistical significance was considered at p < .05. All statistical analyses were performed using IBM SPSS 21.0 (Armonk, NY; IBM Corp). Results from multivariate logistic regression analyses showed that higher likelihood of carbamazepine-induced adverse reactions was significantly associated with younger age, OR = 0.82, 95% CI (0.74, 0.90); p < 0.001. Patients who were prescribed CBZ for reasons other than epilepsy or seizures were significantly more likely to develop carbamazepine-induced adverse reactions (epilepsy vs. other; OR = 0.63, p = 0.013; seizures vs. other; OR = 0.59, p = 0.018). Gender or medication duration were not related to carbamazepine-induced adverse reactions (p > 0.05). The findings of this study are comparable with those of other studies assessing carbamazepine-associated adverse reactions in children and adults. Recommendations include genetic prescreening, educating patients and parents on the possibility of adverse reactions, and routine laboratory monitoring.

Awareness and attitudes of oncology specialists toward dihydropyrimidine dehydrogenase testing in Saudi Arabia.

BACKGROUND: Fluoropyrimidines (FP) are among the most common class of prescribed anti-neoplastic drugs. This class has severe to moderate toxicity in around 10%-40% of those who take 5-fluorouracil (5-FU) or capecitabine for the treatment of cancer. In practice many patients with severe toxicities from FP use had dihydropyrimidine dehydrogenase (DPD) enzyme deficiency. Several studies have proposed DPD screening before treatment with 5-fluorouracil (5-FU) and capecitabine or other drugs belonging to the FP group. This study aims to assess the level of awareness and attitudes of oncology specialists in Saudi Arabia toward genetic screening for DPD prior to giving FP. This highlights the importance of health guidelines required for implementation in our health care system, as a framework to adopt testing as a regular practice in clinical care. Based on the findings in this study, guidelines have been suggested for the Middle East North Africa region. METHODS: A cross-sectional survey study was conducted during 2021 targeting oncologists and clinical pharmacists working in the oncology departments across Saudi Arabia. RESULTS: A total of 130 oncologists and pharmacists completed the questionnaire representing a response rate of 87%. Most of the respondents indicated that they prescribe FP in clinical practice, but 41% of respondents reported that they have never ordered a specific molecular test during their practice. Only 20% of respondents reported that they often screen for DPD deficiency prior to prescribing FP. Significantly higher rates of awareness of potential dihydropyrimidine dehydrogenase gene (DPYD) mutation were observed among respondents in governmental hospitals (81.1% vs. 47.4% in private hospitals), and among those with more years of practice (80.6% if 5 or more years of practice vs. 59.3% if less than 5 years of practice). Also, higher rates of observing the impact of DPD testing were present among respondents with a PharmD (35% vs. 11% for oncologists and 18% for other professions) and among those with 5 or more years of practice (24.6% vs. 7.7% among those with less than 5 years). CONCLUSION: While in some institutions there is a high level of awareness among oncology specialists in Saudi Arabia regarding the effect of the potentially serious DPD enzyme deficiency as a result of gene mutations, screening for these mutations prior to prescribing FP is not a routine practice in hospitals across the country. The findings of this study should promote personalized medicine with recognition of interpatient variability via DPD testing to manage the risks of FP prescribing more effectively in the Kingdom of Saudi Arabia.

Influencing factors of vision-threatening disease among patients with diabetes in the central region of Saudi Arabia: A case-control study.

Aims: Diabetic retinopathy is called as vision threatening disease. It affects retina very severely. DR is a common public health problem in Worldwide. Our main objective was to identify significant risk factors for diabetic retinopathy among diabetes mellitus patients. Materials and Methods: The present retrospective Case-Control study was conducted with 404 DM patients' records were collected from King Abdulaziz Medical City, Riyadh, Saudi Arabia. Statistical analysis used: Data were presented as descriptive statistics, multivariate logistic regression, association between variables was using odds ratio and 95% confidence interval. Results: Among 404 diabetes patients, 192 (47.5%) were Cases and 212 (52.5%) Controls. In multivariate regression analysis showed that male gender also had a higher likelihood in the development of DR, OR: 1. 68 [95% CI: (1.04 - 2.71); p<0.05]. Patients with poor glycaemic control, OR: 4. 86 [95% CI: (2.21-10.66); p<0.001]. Similarly, HbA1C, Low LDL was prominent risk factor in the progression of DR except age, hypocholesterolaemia, nephropathy wasn't significant. Conclusions: From our study findings, male gender, tobacco habit, poor glycaemic control, and Low HDL were appeared independently associated with the development of vision-threatening disease. By regular check-up, reducing risk factors or retain their stages in the same stage or to prolong the DR incidents among DM patients.

Tobacco Taxation Influences the Smoking Habits of Adult Smokers Attending Smoking Cessation Clinic in Saudi Arabia.

Objectives: To determine whether the increased tobacco price due to tax implementation on tobacco products (including cigarettes) has a significant effect on smoking cessation among Saudi Arabian adult smokers. Methods: An interviewer-administered questionnaire was used to obtain data from adult Saudi smokers and recent quitters attending smoking cessation clinics between January 2018 and September 2019. The responses of the participants were summarized and analyzed. Results: In total, 660 participants were interviewed, of which 98% were men who resided in the western region (33%). Taxation had no effect on smoking in 387 participants [58.6%; 95% confidence interval (CI): 54.9, 62.4], some effect in 220 participants (33.3%; 95% CI: 29.7, 36.9), and a substantial effect in 50 participants (7.6%; 95% CI: 5.6, 9.6). Strategies adopted to cope with the tax implementation included cutting down on the number of cigarettes smoked (302; 45.8%), changing to a cheaper brand of cigarette (151; 22.9%), purchasing in bulk (105; 15.9%), attempting to quit (453; 68.6%), and doing nothing (108; 16.4%). The rate of quitting smoking after attending the clinic was 20.7% (95% CI: 17.7, 23.9). Occupation (P = 0.003), education (P = 0.03), and current smoking habit (P = 0.07) were significantly associated with the impact of tobacco taxation. The strategies adopted in response to tax implementation on cigarettes were significantly associated with occupation (χ2 = 30, degrees of freedom = 12, P < 0.001). Conclusions: Tobacco taxation influenced 40% of the participants. Their attempts to opt for alternatives should be recognized in evaluating policies to reduce adverse health impacts caused by tobacco abuse.

Do Multidisciplinary Tumor Board Discussions Correlate With Increase in 5-Year Survival? A Meta-Analysis Study.

Introduction: Due to the complex nature of cancer cases, it is imperative that the involved healthcare providers coordinate the patients care plan in union to reach the best possible outcome in the smoothest and fastest manner. This is what multidisciplinary tumor board (MTB) meetings strive to achieve. Conducting regular MTB meetings requires significant investment of time and finances. It is thus vital to assess the empirical benefits of such practice. Methods: A meta-analysis was conducted to evaluate the literature regarding the impact of MTB meetings on patient 5-year survival. Relevant studies were identified by searching Ovid MEDLINE and Embase databases from January 1995 to July 2019. Studies were included if they assessed 5-year survival in cases discussed in MTB meetings and used a comparison group and/or a pretest and posttest design. Results: Five articles met the study's inclusion criteria. Quality of studies was affected by selection bias and the use of historic cohorts. The results showed significantly improved 5-year survival in the MTB group compared with the non-MTB groups (odds ratio for 5-year death rate of 0.59, CI 0.45-0.78, p < 0.001). Conclusion: This meta-analysis showed that cancer MTB meetings have a significant impact on patients' 5-year survival. This could be because of several reasons, such as less time to treatment initiation, better adherence to guidelines, higher numbers of investigational imaging, lesser surgical complications, and recurrence rates. Future prospective studies are needed to further delineate reasons for improvement of outcome to enhance the benefits of this approach.

Warfarin Dosing Requirement According to Body Mass Index.

Introduction Many factors affect the required dose of warfarin, including body weight, which is mentioned only in a few studies. Our study was conducted using body mass index (BMI) to assess the requirements for warfarin dosing. Methods A retrospective study was conducted that included adults who used warfarin for more than three months, with at least two consecutive international ratio (INR) readings within the therapeutic range. Results Over 301 patients were included; the 20% higher dose of warfarin was required in obese patients than normal BMI and overweight patients (32.2 ± 15.2 vs. 27.4 ±17.3 and 26.8 ± 12.7; p=0.013, respectively). Conclusion Obese patients required a higher dose than other patients, which should be considered when initiating or adjusting the warfarin dose.

The current practice of using angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers in diabetic hypertensive and non-hypertensive patients. Is there a room for vitamin D?

OBJECTIVES: To determine the current pattern of using angiotensin-converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs) in diabetic nephropathy (DN), and assess physician awareness of using vitamin D in the prevention and treatment of DN. METHODS: A cross-sectional study implementing a validated questionnaire, which was distributed to physicians in the aforementioned specialties in 3 hospitals in Saudi Arabia (Almanee Hospital, King Saud Medical City [KSMC], and Riyadh Care Hospital [RCH]) between April 2019 and November 2019. We used IBM SPSS 26.0 to perform descriptive statistical analyses and comparisons were based on the Chi-square test. RESULTS: Forty-one physicians (30%) reported the use of combination therapy of ACEi and ARBs. Fifty-six (41%) physicians reported that they never used vitamin D in the treatment of DN, and 48% agreed that vitamin D can benefit patients with DN. 52% of the respondents reported the existence of guidelines. The vast majority (94%) recommended clearer guidelines on monitoring renal function in patients treated with ACEi or ARBs. CONCLUSION: There is a universal agreement among physicians regarding the use of ACEi and ARBs for the treatment of DN with limited awareness of the bene ts of using vitamin D. Hence, the development of specific guidelines for its use are recommended.

Knowledge regarding Zika Virus Infection among Healthcare Providers in an Academic Tertiary Care Center in Riyadh, Saudi Arabia: A Cross-Sectional Survey Study.

BACKGROUND: Zika virus (ZIKV) has become a major concern across the world. It is highly necessary for healthcare providers (HCPs) to have sufficient knowledge about such a disease. The purpose of this study is to assess the knowledge regarding ZIKV among HCPs in Riyadh, Saudi Arabia. Materials and Methods. A cross-sectional survey study was conducted at a tertiary care center in Riyadh, KSA, during a two-month period from September 19, 2016 to November 19, 2016. Descriptive statistics were performed on data collected. For continuous variables, data were expressed as means ± standard deviations (SDs), medians, and ranges. Proportions were used to describe categorical variables. Knowledge scores were evaluated and compared by demographic characteristics including age, designation, years of practice, and gender, using the t-test/Mann-Whitney U test or the Kruskal-Wallis test, as appropriate. RESULTS: A total of 336 HCPs from different specialties (physicians, dentists, nurses, pharmacists, and nutritionists) completed the questionnaire. Significant differences in knowledge about ZIKV were observed by participant's age. Significantly higher knowledge levels were observed among older participants (45 years or more; p=0.011). A substantial difference in the knowledge level was observed by department, with pairwise comparisons showing significant differences in knowledge scores between all departments except for Pharmacy vs. Nutrition and Nursing vs. Internal Medicine. Knowledge scores were not significantly different by years of practice. CONCLUSION: Our study showed inadequate knowledge of HCPs from different specialties about ZIKV infection which needs to be improved in terms of infection prevention and control. Awareness about ZIKV infection should be ensured and maintained among HCPs to face any possible emergence in the region.

The Burden, Future Trends, And Economic Impact Of Lung Cancer In Saudi Arabia.

BACKGROUND: Incidence of cancer in Saudi Arabia has increased for the last two decades, ratcheting up to global levels. Yet, there is a dearth of research on the burden of lung cancer. This study examined the association between new cases of lung cancer and factors such as gender, age, and year of diagnosis; and forecast new cases and extrapolated future economic burden to 2030. METHODS: This a national-level cohort study that utilized the Saudi Cancer Registry data from 1999 to 2013. Multivariate regression was used; new lung cancer cases forecast and economic burden extrapolated to 20130. Sensitivity analysis was conducted to assess the impact of a range of epidemiologic and economic factors on the economic burden. RESULTS: Of the 166,497 new cancer cases (1999-2013), 3.8% was lung cancer. Males and Saudis had over threefold higher cases compared with females and non-Saudis, respectively. While the age group ≥65 years had 1.14 times or 14% increase in new cases, under-30 years had 97.2% fewer cases compared with age group 45-59. Compared with 1999, the period 2011-2013 had a 106% average increase. The years 2002-2010 registered an average 50% rise in new cases compared to 1999. New cases would rise to 1058 in 2030, an upsurge of 87% from 2013. The future economic burden was estimated at $2.49 billion in 2015 value, of which $520 million was attributable to care management and $1.97 billion in lost productivity. The economic burden for the period 2015-2030 will be $50.16 billion. The present value of this burden in 2015 values will be $34.60 billion, of which 21% will be attributable to care management. Estimates were robust to uncertainty, but the aged-standardized rate and 5-year survival rate would account for much of the variability compared with the economic factors. CONCLUSION: Findings reveal an upsurge of lung cancer burden in incidence and potential economic burden, which may inform cancer control measures.

Practices, awareness and attitudes toward self-medication of analgesics among health sciences students in Riyadh, Saudi Arabia.

BACKGROUND: Self-medication is a common practice among health sciences students in Saudi Arabia. It is known that inappropriate selfmedication may harm individuals due to increasing the risk of drug misuse or delaying a hospital visit by masking some symptoms. Thus, the aim of our study is to investigate and assess practices, awareness and attitudes toward analgesics self-medication among health science students in Riyadh, Saudi Arabia. METHODS: This is a cross-sectional study in a form of electronic survey that was conducted among health sciences students from different universities in Riyadh, Saudi Arabia in 2016. Two hundred and seventy-two students responded to the questionnaire. The electronic questionnaire survey covered demographics, self-medication practice and the analgesics consumption, attitude and awareness about the safety of self-medication practice of analgesics. RESULTS: Factors associated with high prevalence of self-medication were not significant except for age (P = 0.04). Health sciences students had adequate knowledge about the safety of analgesics consumption itself and simultaneous use of analgesics with other drugs, significantly different by college; 80% for Pharmacy, 71% for Medicine, 61% for Nursing and Dentistry, and 25% for Applied Medical Sciences and pre-professional students (p = 0.037). CONCLUSION: The occurrence of self-medication practices is distressingly high among health sciences students. It is necessary to educate the students about the side effects and drawbacks of irresponsible selfmedication.

Pregnant women's use and attitude toward herbal, vitamin, and mineral supplements in an academic tertiary care center, Riyadh, Saudi Arabia.

BACKGROUND: Herbal medicine has been widely utilized by pregnant women despite the limited available evidence regarding the safety and efficacy of that practice. The current available studies, from different countries, estimated that the use of herbal medicine during pregnancy range from 7% up to 96%. The aim of this study is to determine the prevalence, attitude, source of information, and reasoning behind the use of herbal medicine among pregnant women in Saudia Arabia. METHODS: A cross-sectional study conducted using a convenience sample including pregnant women who visited the obstetric clinics at King Abdulaziz Medical City in Riyadh, Saudi Arabia. A survey was administered in order to evaluate the prevalence and perception toward herbal medicine use among pregnant women in Saudi Arabia. RESULTS: A total of 297 pregnant women completed the survey. The results showed that 56% of the respondents have used some type of herbal medicine during their pregnancy. Olive oil was utilized in 26% of the respondents followed by cumin 20% and garlic 15%. In addition, 37% of the respondents used herbal medicine by their own initiative, while 33% and 12% used herbal medicine based on recommendations from their families and friends, respectively. Furthermore, 19% of the respondents reported a positive attitude toward herbal medicine use during pregnancy. In addition, the percentage of women with positive attitude was marginally higher among respondents with lower educational level. CONCLUSION: The prevalence of using herbal medicine is considerably high among pregnant women in Saudi Arabia. Unfortunately, the majority of the users relied on informal sources to use herbal medicine during pregnancy.

Cancer Incidence Trends From 1999 to 2015 And Contributions Of Various Cancer Types To The Overall Burden: Projections To 2030 And Extrapolation Of Economic Burden In Saudi Arabia.

BACKGROUND: Cancer incidence in Saudi Arabia has increased for the last two decades, ratcheting up to global levels. The study aimed to analyze cancer trends and the contributions of various cancer types, forecast incidence, and estimate the economic burden in 2030. METHODS: A national-level cohort study utilizing the Data of Cancer Registry of patients who were diagnosed in 1999-2015. New cases in 2016-2030 were forecast and predicted based on 1999-2015 data. We used growth assumption and regression analysis to predict the trends of cancer cases. We assessed the contributions of cancer types to incidence trends. We carried forecasting of new cases and extrapolation of the potential economic burden. We conducted a sensitivity analysis of the cost of cancer with respect to changes in economic and epidemiologic factors. RESULTS: The findings suggest that the number of known cancer cases increased by 136% from 1999 to 2015 and is projected to rise by 63% in 2030. The forecast indicates female cases will account for higher number of cases and greater proportion increase. The future cost of all cancer types would be estimated at $7.91 billion in 2015 value, of which $3.76 billion will be attributable to care management and $4.15 billion in lost productivity. With the assumption of growth of the aged-standardized incidence rate, the costs of care management and lost productivity are projected to be $5.85 and $6.47 billion, respectively in 2030, an increase of 56% in each component. The future undiscounted total estimated economic burden for the period 2015-2030 would be $159.44 billion, of which 47.5% will be attributable to care management. Estimates were robust to uncertainty, but the 5-year prevalence of cancer survivorship would account for the greatest variability. CONCLUSION: Our model showed an upsurge of cancer burden in terms of incidence and the potential economic burden, which may inform cancer control measures.

Awareness of acute kidney injury risk factors and perspectives on its practice guidelines.

OBJECTIVES: Identifying and assessing risk factors for acute kidney injury (AKI) are crucial for its early detection and possible intervention to prevent AKI and associated adverse outcomes. This study aimed to investigate AKI risk factor awareness and risk assessment by healthcare professionals and to evaluate perspectives on the Kidney Disease Improving Global Outcomes AKI guidelines. METHODS: This cross-sectional survey-based study was conducted among healthcare professionals (physicians and pharmacists) at XXX from December 2016 to February 2017. RESULTS: Among the respondents (117 physicians and 135 pharmacists), 78% were aged ≤38 years, 57% were men, and 70% had <9 years of experience. Respondents varied in their knowledge of the 25 risk factors for AKI and 15 nephrotoxic drugs: 96% were aware of nephrotoxic medication, whereas 20% acknowledged female sex as an AKI risk factor, and 92% agreed with aminoglycoside, while 47% agreed with ciprofloxacin as nephrotoxic drugs. A significantly higher percentage of physicians identified individual AKI risk factors than pharmacists; however, a significantly higher percentage of pharmacists identified individual AKI-causing drugs than physicians. Although 77% of respondents encountered AKI cases in their practice, only half of them performed AKI risk assessment, and 42% stratified patients' AKI risk according to their presenting risk factors or documented AKI in previous medical history. Seventy-one percent of respondents agreed that practice guidelines improve patient outcome, and 69% thought these guidelines help standardize care and ensure that patients are treated in consistently. CONCLUSION: While the majority of the respondents had a positive perspective toward AKI guidelines, a large variation in their knowledge of AKI risk factors, risk assessment, and nephrotoxic drugs was found. Educational efforts are needed to raise awareness and thereby reduce this variation.

Medical students' attitude toward anesthesia as a future career.

OBJECTIVES: The purpose of this study is to understand the attitude of medical students at King Saud bin Abdulaziz University for Health Sciences (KSAU-HS) toward anesthesia as a specialty and to determine common factors influencing their career choice options. STUDY DESIGN: This was a cross-sectional study. METHODS: The study was conducted between March 25, and April 20, 2017, at KSAU-HS. The survey was distributed among 5th and 6th years medical students. Data were collected through a validated hardcopy questionnaire of 16 multiple choice questions. The questionnaire included demographic characteristics, specialty preferences, what factors attract Saudi medical students to choose their preferred specialty and how they view the option of choosing anesthesiology as a career. RESULTS: A total of 236 students completed the questionnaire. The majority of respondents were in their 5th year of medical school representing (62%). The distribution of medical field interest ranged from (38%) surgery to (1%) anesthesiology. approximately, (60%) thought that controllable lifestyle was an important factor to consider in choosing a residency program. Only (45%) of respondents thought that prestige of specialty is a major factor that would influence their choice for a specialty. CONCLUSION: Based on the outcome of the study, it is recommended that medical undergraduate students exposure to anesthesia specialty should be magnified. Greater efforts have to be made to increase the number of medical students preferring anesthesia through emphasizing on the positive aspects of the specialty.

Validity and reliability of the Arabic version of the the EuroQOL (EQ-5D). A study from Saudi Arabia.

OBJECTIVES: The EuroQOL five-dimension questionnaire (EQ-5D) is one of the most widely used tools to evaluate health-related quality of life (HRQOL). Studies on the psychometric features of the EQ-5D in the Gulf region of the Middle East are lacking. This study is aimed at evaluating the validity and reliability of the Arabic version of the EQ-5D in Saudi Arabia. METHODS: The study was done utilizing a convenience sample of Arabic-speaking adult patients or visitors at the outpatient clinic at King Abdulaziz Medical City (KAMC) in Riyadh during October-December 2015. Participants were interviewed using translated into Arabic versions of the EQ-5D and the Short Form Health Survey (SF-36). Known-group construct validity of the EQ-5D and visual analog scale (EQ-VAS) was assessed through testing a number of hypotheses comparing responses to EQ-5D dimensions or EQ-VAS to SF-36 scores by dimension and external variables. Test-retest reliability was also assessed. RESULTS: Eighty subjects were included in the study. Mean ± standard deviartion age was 33.0 ± 11.6 years, with 51% of females. Responses to EQ-5D dimensions revealed that the proportion of respondents reporting problems ranged from 6% for problems with self-care to 48% for pain/discomfort. All of the five hypotheses linking EQ-5D responses to external variables were satisfied. Test-retest reliability was evaluated using Cohen's κ, which ranged from 0.53 to 1.00. CONCLUSION: Validity and reliability of the Arabic EQ-5D were established for evaluating HRQOL in Saudi Arabia. Further studies are warranted to evaluate the validity and reliability of this standard tool in other Arabic-speaking countries with varying cultures.

The validity and reliability of the Arabic version of the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU): A prospective cohort study.

BACKGROUND: Accurate diagnosis for Arabic speaking critically ill patients suffering from delirium is limited by the need for a valid/reliable translation of a standardized delirium instrument such as the Confusion Assessment Method for the ICU (CAM-ICU). OBJECTIVE: To determine the validity and reliability of the Arabic version of the CAM-ICU. DESIGN: A prospective cohort study design was used to conduct the current study. SETTINGS: Data collection took place in Geriatric, Emergency and Surgical intensive care units. PARTICIPANTS: Fifty-eight adult patients met the inclusion criteria and participated in the study. Among the participants 22(38%) patients were on mechanical ventilation. METHODS: After translating the CAM-ICU into Arabic language, the Arabic CAM-ICU was administered by two well-trained critical care nurses and compared with reference standard assessments by delirium experts using the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision (DSM -IV-TR), along with assessment of severity of illness using Sequential Organ Failure Assessment (SOFA). Concurrent validity was assessed by calculating sensitivity, specificity and positive and negative predictive value (PPV and NPV) for the two Arabic CAM-ICU raters, where calculations were based on considering the DSM-IV-TR criterion as the reference standard. The convergent validity of the Arabic CAM-ICU was explored by comparing the Arabic CAM-ICU ratings and the total score of SOFA (severity of illness) and MMSE (cognitive impairment). RESULTS: A total of 58 ICU patients were included, of whom 27 (47%) were diagnosed with delirium during their ICU stay via DSM-IV criteria. Interrater reliability for the Arabic CAM-ICU, overall and for mechanically ventilated patients assessed using Cohen's kappa (κ) were 0.82 and 1, respectively, p < 0.001. The sensitivities (95% CI) for the two critical care nurses when using the Arabic CAM-ICU compared with the reference standard were 81% (60%-93%) and 85% (65%-95%), respectively, whereas specificity (95% CI) was 81%(62%-92%) for both nurses. High sensitivity and specificity measures were also observed across subgroups; 100% for mechanically ventilated patients, 88% (60%-98%) and 79% (49%-94%) for those aged 65 years or older and 82% (56%-95%) and 75% (43%-93%) for those with SOFA scores at or above the median value. CONCLUSIONS: The Arabic CAM-ICU appeared to be valid and reliable tool for diagnosing delirium. Future investigations may lead to a better understanding of the prevalence, predictors, and consequences of delirium among critically ill Arabic speaking patients.

Acute Kidney Injury in Pediatric Treated with Vancomycin and Piperacillin-Tazobactam in Tertiary Care Hospital.

BACKGROUND: Vancomycin and piperacillin-tazobactam (PTZ) are commonly used as empirical therapy for patients with health care associated infections. Vancomycin has been recognized as a nephrotoxic agent and in a few cases in the literature PTZ has been associated with interstitial nephritis nevertheless; the combination of these agents has routinely been used for many years. However, there have been some observational studies that showed high rates of acute kidney injury (AKI) in patients receiving vancomycin and PTZ concomitant treatment compared to patients receiving vancomycin alone. The incidence of AKI in adult patients receiving vancomycin and PTZ concomitant treatment was reported in these studies to be relatively high. Similar studies in pediatric patients are lacking. METHOD: We conducted a single center retrospective chart review of 248 pediatric patients receiving one of the following treatments: vancomycin alone 36 patients, vancomycin/PTZ 62 patients, vancomycin/ceftazidime 99 patients, and vancomycin/ceftriaxone 51 patients. RESULT: Our results showed a low incidence of AKI in patients on vancomycin/PTZ concomitant treatment where overall incidence was only (4.8%) three cases and only one of them (2.0%) in a patient receiving the vancomycin/ceftriaxone concomitant treatment. No cases of AKI present in patients receiving vancomycin with ceftazidime or vancomycin alone. There were no statistically significant differences between the four treatment groups in terms of AKI incidence, vancomycin trough, and use of nephrotoxins. CONCLUSION: Overall, the incidence of AKI was low in our study sample with no statistically significant increased risk when PTZ was used in combination with vancomycin in a pediatric population. However, further investigation with an equal larger sample size is needed to confirm our findings.
