Assessment of Public Knowledge about Chronic Kidney Disease and Factors Influencing Knowledge Levels: A Cross-Sectional Study.

Background and Objectives: Chronic kidney disease (CKD) poses a significant risk for end-stage renal disease (ESRD), cardiovascular diseases, and premature death. The study aims to assess CKD knowledge and predictive variables among the general public. Materials and Methods: A cross-sectional study was conducted among the general public in Al Medina Al-Munawara, Saudi Arabia, utilizing a 21-item questionnaire-based approach over a 4-month period from January 2023 to April 2023. The developed questionnaire was validated for readability by experts and refined in light of the feedback received from the experts and the final version was prepared. The reliability of the questionnaire was 0.71, which shows an acceptable level of internal consistency. The data analysis was performed using IBM SPSS software (version 25). Results: A total of 777 complete surveys were received after applying the exclusion criteria. The study results revealed that the majority of the respondents had poor knowledge 505 (65%), 203 (26.1) had moderate knowledge, and 69 (8.9%) had good knowledge. Gender (p = 0.004), age (<0.001), education level (p = 0.039), marital status (p = 0.003), and occupation (p = 0.002) play significant roles in shaping participants' knowledge levels regarding CKD. Lower odds of good knowledge were associated with females with an OR (95% CI) of 0.448 (0.263-0.764) and intermediate or higher secondary school level of education displayed an OR (95% CI) of 0.39 (0.18-0.89). Higher odds of good knowledge levels were associated with the age group of 18-27 with an OR (95% CI) of 5.077 (1.21-21.38) and being employed with an OR of 3.555 (1.04-12.21). Conclusions: A significant proportion of respondents had poor knowledge about CKD. Several demographic factors were associated with CKD knowledge. Further research is needed to explore these knowledge disparities and develop targeted interventions to improve CKD knowledge among the general public.

Effectiveness and safety of edoxaban versus warfarin in patients with nonvalvular atrial fibrillation: a systematic review and meta-analysis of observational studies.

Background: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia type. Patients with AF are often administered anticoagulants to reduce the risk of ischemic stroke due to an irregular heartbeat. We evaluated the efficacy and safety of edoxaban versus warfarin in patients with nonvalvular AF by conducting an updated meta-analysis of real-world studies. Methods: In this comprehensive meta-analysis, we searched two databases, PubMed and EMBASE, and included retrospective cohort observational studies that compared edoxaban with warfarin in patients with nonvalvular AF from 1 January 2009, to 30 September 2023. The effectiveness and safety outcomes were ischemic stroke and major bleeding, respectively. In the final analysis, six retrospective observational studies involving 87,236 patients treated with warfarin and 40,933 patients treated with edoxaban were included. To analyze the data, we used a random-effects model to calculate the hazard ratio (HR). Results: Patients treated with edoxaban had a significantly lower risk of ischemic stroke [hazard ratio (HR) = 0.66; 95% confidence interval (CI) = 0.61-0.70; p < 0.0001] and major bleeding (HR = 0.58; 95% CI = 0.49-0.69; p < 0.0001) than those treated with warfarin. The sensitivity analysis results for ischemic stroke and major bleeding were as follows: HR = 0.66; 95% CI = 0.61-0.70; p < 0.0001 and HR = 0.58; 95% CI = 0.49-0.69; p < 0.0001, respectively. Conclusion: Our findings revealed that edoxaban performed better than warfarin against major bleeding and ischemic stroke.

Uptake, Safety and Attitudes Towards COVID-19 Vaccination: A Cross-Sectional Study on First and Second Doses Among the General Public.

Objective: To investigate public uptake, attitudes and the safety of the first and second doses of COVID-19 vaccination. Methods: This was a cross-sectional web-based survey study. A self-administered questionnaire was prepared from a literature search and information about COVID-19 available at various resources. The developed questionnaire was validated for readability by experts and refined in light of the feedback received from the experts and the final version was prepared. The reliability of the questionnaire was 0.7 which shows an acceptable level of scale internal consistency. The data analysis was performed using IBM SPSS software (version 25). Results: A total of 513 participants completed the survey, including 311 (60.6%) women and 202 (39.4%) men. The mean age was (31.5±12.8) years. It was found that 493 (96.1%) took the first and second doses of COVID-19 and 376 (73.3%) suffered from side effects, of these 14% (56/376) reported the side effects to the health authorities. The most common side effects were fatigue (51.5%), fever (42.3%), headache (39.5%), and injection site pain (37.6%). Half of the participants (50.5%) had a positive attitude towards COVID-19 preventive measures. Females had higher odds of experiencing side effects than males OR (95% CI); 2.002 (1.312-3.056). Individuals living in urban areas had lower odds of experiencing side effects than those living in rural areas OR (95% CI); 0.364 (0.142-0.933). Conclusion: Vaccine uptake was massive and side effects due to the COVID-19 vaccine were common but minor. The majority of the participants had positive attitudes towards recommended COVID-19 preventive measures. Being female and living in rural areas were associated with experiencing side effects.

The Contraindications to Combined Oral Contraceptives among Reproductive-Aged Women in an Obstetrics and Gynaecology Clinic: A Single-Centre Cross-Sectional Study.

This study aimed to determine the estimated proportion of contraindications among women taking combined oral contraceptives (COCs) and to assess the risk factors associated with their contraindications. This study was cross-sectional. Reproductive-aged women (18-49 years) on any COCs between 2018 and 2020 were recruited from one obstetrics-gynaecology clinic in a university-affiliated hospital and were included. Contraindications were defined using the World Health Organization (WHO) Medical Eligibility Criteria (MEC) for Contraceptive Use. Data were collected from electronic medical records for all included women, as well as a standardised, pretested, structured survey for one-third of the women. In this cross-sectional study, 380 women using COCs were included. Their mean age was 31.645 ± 7.366 years. Among them, 131 (34.5%) participated via a survey and electronic records, while the other 249 (65.5%) participated via electronic records only. The majority of the participants had a Bachelor's degree (59.0%) and were married (62.1%). The overall estimated proportion of patients with at least one contraindication to COCs according to category 3 (relative contraindications) or 4 (absolute contraindications) was 31.3% (95% CI 26.63-35.99). The most common contraindications observed were controlled hypertension, category 3 (12.1%); major surgery with prolonged immobilisation, category 4 (4.7%); migraine with aura at any age, category 4 (4.2%); breastfeeding from six weeks to less than six months postpartum, category 3 (4.0%); and diabetes mellitus with complications, category 4 (3.2%). Significant factors associated with contraindications to COCs were married women (OR 2.19, 95% CI 1.38-3.46), those aged 35 years or more (OR 2.33, 95% CI 1.49-3.66), and those with one or more live births (OR 2.19, 95% CI 1.38-3.46). Ensuring proper assessment prior to prescribing and considering alternatives suitable for long-term use among women taking an oral contraceptive regularly is recommended.

Knowledge and Barriers Among Physicians Toward Adverse Drug Reaction Reporting at a Tertiary Care Hospital in Saudi Arabia.

BACKGROUND: Spontaneous reporting systems are essential as they help detect serious unknown adverse drug reaction (ADR). However, underreporting of ADR is a commonly associated problem. This research work aims to assess knowledge, barriers, and factors that encourage the reporting of ADR among physicians. METHODS: A total of 600 physicians working at a tertiary referral hospital in Riyadh, Saudi Arabia, were included in this cross-sectional study. A pretested questionnaire was used. RESULTS: Out of the 600 physicians, 240 (40%) completed the questionnaire. Most of the participants (85.4%) could correctly define ADR; nearly 75% physicians were unaware of the spontaneous reporting of ADR in Saudi Arabia. A total of 175 (72.9%) physicians had not reported any ADR among their patients in the last year; 40% of the physicians said that they did not report ADR because they were unaware of the online reporting of ADR. Providing guidelines and regular bulletins on the reporting of ADR is a critical aspect that encourages physicians to report ADR (51%). Education and training are the most recognized measures for improving the reporting of ADR. CONCLUSION: Physicians were adequately aware of ADR but inadequately aware of the reporting system and reporting authorities. Continuing medical education, training, and integration of the reporting of ADR into physicians' various clinical activities may improve ADR reporting.

Prevalence and Factors Associated With Polypharmacy Use Among Adult Patients in Saudi Arabia.

BACKGROUND: Polypharmacy is very common in clinical practice, especially among adult patients. The use of multiple medications may increase the risk of adverse drug events, medication cost, and medication errors. In addition, polypharmacy exacerbates treatment complexity, which consequently leads to poor patients' adherence to their medications. Despite being a well-recognized problem, few studies have investigated the prevalence and predictors of polypharmacy in Saudi Arabia. OBJECTIVES: The aims of the study were to investigate the prevalence of polypharmacy among adult patients in a tertiary teaching hospital and to determine patients' characteristics that are associated with polypharmacy. METHODS: This was a retrospective cross-sectional study using data extracted from the electronic health records database for a period of 6 months between January and June 2016 in outpatient setting. Descriptive statistics were used to analyze the study sample. A multivariate logistic regression model was used to examine the association between different variables and polypharmacy. Statistical analysis software (SAS 9.2) was used to analyze the study data. RESULTS: A total of 17,237 observations (67.2% females) were included in the final analysis. Of these, nearly 54% (n = 9222) of reported observations were found using up to four prescription drugs and the other 46% (n = 8015) were using five or more prescription drugs. Interestingly, the prevalence of polypharmacy use was doubled among adults with hypertension as compared with those without hypertension (odds ratio [OR] = 2.68, 95% confidence interval [CI] = 2.51-2.87). In addition, polypharmacy use was two times more prevalent among adults with diabetes as compared with those without diabetes (OR = 2.31, 95% CI = 1.99-2.28) and five times more prevalent in patient with dementia (OR = 5.57, 95% CI = 1.26-24.7). Moreover, polypharmacy in adult patients was significantly influenced by sex (OR = 1.69, 95% CI = 1.59-1.80) and nationality (OR = 2.15, 95% CI = 2.00-2.31). CONCLUSIONS: Polypharmacy is common among adult patients especially those who are older than 60 years. Polypharmacy may affect the overall process of drug therapy. It can be a risk factor to develop undesirable adverse drug events, especially in those with chronic health conditions. A special care should be taken to manage polypharmacy among adults in Saudi Arabia.

Knowledge, Attitude, and Practice of General Population toward Complementary and Alternative Medicines in Relation to Health and Quality of Life in Sungai Petani, Malaysia.

PURPOSE: The demand of complementary and alternative medicine (CAM) has increased drastically over the past few decades. The perceptions about CAMs among general population are positive. However, the literature highlights that effectiveness and acceptance of alternative therapies among the general population is still a subject of debate. MATERIALS AND METHODS: This is a cross-sectional study and the response along with demographic details was collected through a validated questionnaire; the results were analyzed by using a validated data collection tool. The results were concluded based on good, moderate, and poor responses, which were evaluated through data analysis by using the Statistical Package for the Social Sciences software version 20.0., SPSS Inc., Chicago, III, USA. A value of P < 0.05 was considered statistically significant. RESULTS: In total, 182 (44.4%) of male and 228 (55.6%) of female respondents were selected for this study. Studies showed that a greater knowledge level was observed among female respondents (15.55 ± 2.7, P < 0.001). The selected Chinese population had relatively good knowledge (i.e., 15.63, P = 0.006). People practicing Buddhism had also good knowledge. Rural population had lesser family income and showed a good practice pattern and understanding (P = 0.006). The positive attitude was identified among women ( P < 0.001) with a mean score of 15.55 ± 2.7. Postgraduate participants were found to have diverse results with SD ± 6.23, and 77.1% had a good attitude. A statistically significant association was observed between religion and attitude of respondents (P < 0.001). CONCLUSION: Although a better practice was noticed in Malaysian population, more awareness is required and knowledge should be disseminated among the population to improve the overall health and quality of life in Malaysia.

Factors that facilitate reporting of adverse drug reactions by pharmacists in Saudi Arabia.

Objectives: Adverse drug reactions (ADRs) are a pervasive global problem, and its management is integral to patient safety and healthcare quality. Pharmacists play a pivotal role in monitoring and reporting ADRs, which has a direct impact on patient care. The aim of this study was to identify potential factors that facilitate pharmacists in community and hospital settings to report ADRs. Methods: A cross-sectional, online survey using a validated questionnaire was administered to pharmacists working in community and hospital pharmacies in Saudi Arabia. Results: 1,717 community and 153 hospital pharmacists participated in this study. Only 10.2% and 26.8% of community and hospital pharmacists, respectively, admitted ever reporting an ADR. The most reported factors that may facilitate ADRs reporting have included ongoing improvements in therapeutic knowledge about ADRs, attending educational programs with continuous medical education credits, the seriousness of the experienced ADRs and accessibility to patients' medical profile. The impact of peers by seeing colleagues reporting ADRs and ADRs due to herbal or traditional medicine were the least important factors reported by pharmacists. Conclusion: The study identified factors that can effectively address the under-reporting of ADRs by pharmacists. A multi-stakeholder, multi-pronged approach of ADR reporting is needed to develop greater awareness of this issue among pharmacists.

Measuring the quality and completeness of medication-related information derived from hospital electronic health records database.

OBJECTIVE: Electronic Health Records (EHRs) database is a great source for pharmacoepidemiological research as thousands of patients' clinical and medication information is stored in the database. However, the use of EHRs database for research purposes depends greatly on the accuracy and completeness of the data being used. This study mainly aimed to assess the completeness of EHRs patients' medication-related information. DESIGN: A retrospective cross-sectional study using data extracted from the EHRs database was conducted. SETTING: The EHRs data was obtained from a single tertiary hospital in Saudi Arabia. MAIN OUTCOME MEASURES: The completeness of data was measured considering if a patients' record contains all desired types of data (i.e., patients' demographics, clinical diagnosis, and medication-related information). RESULTS: A total of 23,411 unique individuals were identified after extracting the data from the EHRs. The study found that 89.9% of the patients had a complete data (i.e., age, gender, marital status, nationality, encounter type, and clinical diagnosis). Further, 83.1% of the patients had complete medication-related information. Subgroup analysis by the encounter type indicated that the data was 91.0% complete for outpatient encounter and 93.2% complete for inpatient encounter. CONCLUSION: The study findings indicate that the completeness of the data varies by the desired types of data. EHRs can be a potentially great resource to conduct research to assess medication use. Further studies focusing on the content and completeness of EHRs for a specific patient population and evaluate other dimensions of EHRs data quality are needed.

Advancing pharmaceuticals and patient safety in Saudi Arabia: A 2030 vision initiative.

Low-quality medicines deliver sub-optimal clinical outcomes and waste precious health resources. It is important to ensure that public funds are spent on healthcare technologies that meet national regulatory bodies such as the Saudi Food and Drug Authority (SFDA), quality standards for safety, efficacy, and quality. Medicines quality is a complicated combination of pre-market regulatory specifications, appropriate sourcing of ingredients (active pharmaceutical ingredient (API), excipients, etc.), manufacturing processes, healthcare ecosystem communications, and regular and robust pharmacovigilance practices. A recent conference in Riyadh, sponsored by King Saud University, sought to discuss these issues and develop specific policy recommendations for the Saudi 2030 Vision plan. This and other efforts will require more and more creative educational programs for physicians, pharmacists, hospitals, and patients, and, most importantly evolving regulations on quality standards and oversight by Saudi health authorities.

Public awareness and perception toward Adverse Drug Reactions reporting in Riyadh, Saudi Arabia.

Purpose: To assess the general public awareness and perception about Adverse Drug Reactions (ADRs) reporting and pharmacovigilance. Method: A cross-sectional study conducted on June 2012 during awareness campaign held in two malls in Riyadh city for two days. A self-administered questionnaire consisting of three parts was distributed to the attendees who accepted to participate in the study. Results: A total of 204 questionnaires were collected with a response rate of 68%. Twenty-three percent could correctly define ADRs. Only 13(15.7%) of responders were familiar with the term "Pharmacovigilance" and only 78.6% were aware about the Saudi Pharmacovigilance Center. Sixty-seventy percent indicated that their physicians or pharmacists don't actively encourage them to report ADRs that may occur when they take their medications. The majority of responders (73.2%) believed that the medical team, rather than consumers, should report ADRs. When asked why patients do not report ADRs, 19.1(48.5%) believed that patients do not know whether the ADR is from the medication or not, 18.1(46.1%) stated that the reason was because patients don't know about the Pharmacovigilance Center, 16(40.7%) think that patients don't know about the importance of ADRs reporting, and 14(36.3%) responded that patients probably don't know how to report ADRs. Conclusion: The general public in Saudi Arabia are not aware about ADRs reporting and the pharmacovigilance system. The Saudi Food and Drug Authorities (FDA) need to put more efforts to increasing public awareness about the importance of ADRs reporting process and the importance of pharmacovigilance system in promoting patient safety.

Incidence of adverse drug events in public and private hospitals in Riyadh, Saudi Arabia: the (ADESA) prospective cohort study.

OBJECTIVES: To determine the incidence of adverse drug events (ADEs) and assess their severity and preventability in four Saudi hospitals. DESIGN: Prospective cohort study. SETTING: The study included patients admitted to medical, surgical and intensive care units (ICUs) of four hospitals in Saudi Arabia. These hospitals include a 900-bed tertiary teaching hospital, a 400-bed private hospital, a 1400-bed large government hospital and a 350-bed small government hospital. PARTICIPANTS: All patients (≥12 years) admitted to the study units over 4 months. PRIMARY AND SECONDARY OUTCOME MEASURES: Incidents were collected by pharmacists and reviewed by independent clinicians. Reviewers classified the identified incidents as ADEs, potential ADEs (PADEs) or medication errors and then determined their severity and preventability. RESULTS: We followed 4041 patients from admission to discharge. Of these, 3985 patients had complete data for analysis. The mean±SD age of patients in the analysed cohort was 43.4±19.0 years. A total of 1676 ADEs were identified by pharmacists during the medical chart review. Clinician reviewers accepted 1531 (91.4%) of the incidents identified by the pharmacists (245 ADEs, 677 PADEs and 609 medication errors with low risk of causing harm). The incidence of ADEs was 6.1 (95% CI 5.4 to 6.9) per 100 admissions and 7.9 (95% CI 6.9 to 8.9) per 1000 patient-days. The occurrence of ADEs was most common in ICUs (149 (60.8%)) followed by medical (67 (27.3%)) and surgical (29 (11.8%)) units. In terms of severity, 129 (52.7%) of the ADEs were significant, 91 (37.1%) were serious, 22 (9%) were life-threatening and three (1.2%) were fatal. CONCLUSIONS: We found that ADEs were common in Saudi hospitals, especially in ICUs, causing significant morbidity and mortality. Future studies should focus on investigating the root causes of ADEs at the prescribing stage, and development and testing of interventions to minimise harm from medications.

An assessment of the basic medication safety practices in Khartoum State hospitals.

PURPOSE: To assess the presence of medication safety practices in Khartoum State hospitals. METHODS: A previously used questionnaire was used to evaluate medication safety practices. The main practices evaluated were the presence of a medication safety committee and error-reporting system, look-alike sound-alike (LASA) medications list, control of concentrated electrolyte solutions, care transitions, information technology, drug information and other medication safety practices. The primary investigator visited a stratified sample from all the three cities that comprise Khartoum State and interviewed the pharmacy supervisor of each hospital. Descriptive statistics were performed using SPSS V.22. RESULTS: A total of 41 senior pharmacists or pharmacy supervisors from 41 hospitals were interviewed. Only 2% of the hospitals had a list of LASA medications and 5% had a list of error-prone abbreviations. Only 5% of the hospitals had a medication safety committee, and none of the hospitals had a medication safety officer. None of the hospitals involved pharmacists in obtaining medication histories. Concentrated electrolytes were available in the floor stock in 67% of the hospitals. Although 24% of the hospitals used a computer system in their pharmacy to enter prescriptions, none of these hospitals required entry of patient allergies before entering a drug order. CONCLUSIONS: Most of the hospitals in Khartoum State did not implement basic medication safety practices. Therefore, the Ministry of Health in Sudan should enforce laws and regulations making implementation of medication safety practices mandatory to ensure patient safety.

Implementation of safety standards of compounded sterile preparations in hospital pharmacies: a multinational cross-sectional study.

OBJECTIVES: To evaluate implementation of safety standards of compounded sterile preparations in different hospitals. METHODS: This cross-sectional study included 124 hospitals from 19 countries. A survey was developed based on the guidelines and safety practices of the Institute for Safe Medication Practices (ISMP) for sterile preparations compounding, and was sent to the members of the Intravenous and Parenteral Nutrition experts' network (IV PN experts' network) in the Gulf region and beyond using SurveyMonkey software. RESULTS: 124 pharmacists were invited to participate in this study. Only 39 (31.5%) pharmacists from seven countries responded: 16 (41%) of the participants were pharmacy supervisors, and 23 (59%) had >10 years of work experience. However, a majority, 27 (69%), of the respondents were from Saudi Arabia. Written policies and procedures for sterile preparations compounding were available in 37 (95%) hospitals. The concentrated electrolytes were removed from all patient care areas in 28 (72%) hospitals, and 30 (77%) hospitals clearly labelled those as high-alert medications. The use of advanced technologies, such as bar code verification or IV robotics, for compounding sterile preparations were not implemented in 27 (69%) hospitals. CONCLUSIONS: Minimum standards and best practice recommendations to ensure safety of sterile preparation compounding were implemented in many hospitals of different countries. However, advanced technologies were not implemented by the majority of the hospitals.

A qualitative exploration of the major challenges facing pharmacovigilance in Saudi Arabia.

OBJECTIVES: To explore the challenges facing pharmacovigilance in Saudi Arabia and formulate recommendations to improve it from the perspective of healthcare professionals in Saudi Arabia. METHODS: This was a qualitative study of 4 focus group discussions with pharmacists, physicians, and academicians held under the auspices of the King Saud University School of Pharmacy and the Center for Medicine in the Public Interest, Riyadh, Saudi Arabia. A total of 29 eligible healthcare professionals were invited to participate in the discussion. The predefined themes of the study were the current practice and major challenges facing pharmacovigilance in regulatory bodies, hospitals, the community, and academia, as well as recommendations to improve pharmacovigilance practice.  RESULT: Of the 29 participants invited, 27 attended the discussion. Challenges facing regulatory bodies included complicated adverse drug reactions (ADR) reporting forms, lack of feedback on ADRs submitted to the Saudi Food and Drug Authority, lack of decisions from the local authority to withdraw medications, and lack of data on pharmacovigilance. The challenges to pharmacovigilance in hospitals included the lack of knowledge of the significance of ADR reporting, workload, blaming culture, and lack of collaboration between regulatory bodies and hospitals. However, challenges facing pharmaceutical industries included the lack of drug manufacturers in Saudi Arabia and lack of interest in pharmacovigilance. Recommendations to improve pharmacovigilance included the need for communication, stronger regulatory requirements, the need for research, the need for unified ADRs reporting, and continuous education and training.  CONCLUSION: The study has identified the challenges facing pharmacovigilance in Saudi Arabia and made certain recommendations to overcome them. These recommendations might be helpful for regulatory bodies to enhance spontaneous reporting and promote pharmacovigilance.

Self-medication in Central Saudi Arabia. Community pharmacy consumers' perspectives.

OBJECTIVES: To determine the prevalence of self-medication and assess the knowledge, attitudes, and perception of consumers toward self-medication. METHODS: This cross-sectional survey was conducted over 4 weeks in May 2011 in Riyadh city, Kingdom of Saudi Arabia. Community pharmacies within 5 areas of the city (North, South, West, East, and Middle) were randomly selected for the study. All consumers were approached to participate in the study, with the exception of those buying cosmetic and medicinal equipments. A validated self-administered questionnaire was used to collect the data. RESULTS: A total of 538 out of 707 consumers attending community pharmacies in Riyadh city, agreed to participate in the study. Most responders were male (73%), 23-33 years old (35%), and college graduates (42%). A total of 285 medications were bought without a prescription. Of these, 149 (49%) medications should be dispensed by prescription only, and 155 (51%) were over the counter medications. The most common prescription medications dispensed without prescriptions were antibiotics (22%) and analgesics/antipyretics (19%). The most common reasons for buying medications without a prescription were that the symptoms were too minor to visit a doctor (54%), time saving (40%), and minor illnesses for which the participants knew the required treatment (40%). Overall, most participants had poor knowledge, and negative perceptions regarding self-medication. More than 68% of participants did not know whether the medicine they bought is a prescription-only or over the counter medication. CONCLUSION: Irresponsible self-medication is common in Saudi Arabia. Future studies should focus on improving the consumers' awareness of self-medication and the proper use of medications.

Knowledge and attitude of healthcare professionals toward medication pregnancy category systems in Saudi hospitals.

OBJECTIVE: To assess the knowledge and attitudes of healthcare professionals (HCPs) toward systems used in describing the safety of medications use during pregnancy. METHODS: A cross-sectional self-administered survey was conducted in 4 tertiary hospitals in Riyadh, Saudi Arabia between March and May 2012. The targeted HCPs were physicians and pharmacists. The survey was validated and contained 4 main sections. Descriptive statistics were used to report responses to the survey's questions. RESULTS: A total of 393 HCPs responded to the survey, with a response rate of 97%. Half of the respondents were physicians. Of the participants, 60% were males. Most respondents (66%) stated that they have prescribed/dispensed a drug that may cause teratogenicity. Moreover, 87% of the respondents (48% pharmacists and 39% physicians) were aware of the Food and Drug Administration (FDA) pregnancy category, and most (72%) found it helpful. Only 11% of the participants strongly agree to use the European Medicine Agency (EMA) system for pregnancy category system as their main reference. CONCLUSION: In general, HCPs in Saudi Arabian hospitals have good knowledge of and attitudes toward pregnancy category systems, with more familiarity with the FDA system. The FDA system is preferred over the EMA system.

Incidence of adverse drug events in an academic hospital: a prospective cohort study.

OBJECTIVE: To determine the incidence of adverse drug events (ADEs) and assess their severity and preventability. DESIGN: A prospective cohort study. SETTING: A 900-bed tertiary academic hospital. PARTICIPANTS: A total of 977 patients admitted to two medical, one surgical and two intensive care units over four months. MAIN OUTCOME MEASURES: The primary outcomes were the incidence of ADEs, preventability of ADEs, potential ADEs and medication errors. A physician and a clinical pharmacist independently determined the likelihood that incidents were caused by medications and judged severity and preventability. RESULTS: Pharmacists reviewed the medical records of the 977 patients. Pharmacists identified 361 incidents, of which 281 (78%) were considered to be an ADE, potential ADE or medication error by reviewers. The incidence of ADEs was 8.5 per 100 admissions (95% confidence interval (CI) 6.8-10.4), with the highest rate found in the intensive care unit (21.1 per 100 admissions) (95% CI 15.1-28.8). Of all ADEs, 59% were rated as significant, 35% as serious and 6% as life threatening. Thirty percent of ADEs were preventable and 96% of these occurred in the ordering stage. The incidence of potential ADEs was 13.8 per 100 admissions (95% CI 11.5-16.2). Overall, 223 medication errors were identified, 66 (30%) were harmless, 132 (59%) had the potential to cause harm and 25 (11%) resulted in harm. CONCLUSIONS: The incidence of ADEs in a Saudi Hospital was 8.5 per 100 admissions. Preventable ADEs most commonly occurred in the ordering stage; therefore, interventions to reduce ADEs should target the ordering stage.

Knowledge on adherence and safety of the oral contraceptive pill in Saudi women.

OBJECTIVE: To assess knowledge regarding adherence and safety of oral contraceptive pills (OCP) in Saudi women. METHODS: We conducted a cross-sectional prospective study in an outpatient pharmacy at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia from April to September 2011. Participants were healthy women aged greater than or equal to 18 years with an OCP prescription for contraception. We used a validated questionnaire to assess their knowledge regarding adherence and safety of OCPs. RESULTS: Four hundred and sixty women participated. Most (79%) knew to take an extra pill if they missed one in less than 12 hours, but only 6.5% knew they also had to use extra protection for the next 7 days if it was more than 12 hours. Multiple logistic regression analyses indicated that years of contraceptive use and educational level are predictive factors of better knowledge regarding adherence. Few were aware of the action if they experienced diarrhea for more than 12 hours (10%) or vomiting within 2 hours (13.5%) of taking an OCP. Only 30% knew of the adverse effects of smoking while on OCPs. Weight gain (51%) was the most commonly reported side effect. CONCLUSION: Most Saudi women taking OCPs have limited knowledge of its correct use regarding missing pills, vomiting and diarrhea, and poor awareness of the effects of smoking while using OCPs.
