Hospital pharmacists in the Riyadh region are actively engaged in monitoring medication therapy and providing patient medication education, although there is considerable opportunity for further involvement.

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.

Hospital pharmacies in the Riyadh region are fairly well developed in providing dispensing and administration services. Further improvement can be achieved by increasing the use of new technologies such as bar-code technology, unit dose drug distribution systems, pharmacy-based IV admixture services, smart infusion pumps, and automated medication distribution.

Medication errors are underreported in a tertiary teaching hospital in Riyadh, Saudi Arabia. Future studies should evaluate the effectiveness of interventions to stimulate medication errors reporting by health-care providers.

The purpose of the study was to assess the knowledge, attitudes, beliefs, and factors associated with the uptake of the influenza (flu) vaccination in women within Saudi Arabia during their pregnancy period. A cross-sectional prospective survey was conducted on 1085 pregnant women at the antenatal clinic over a period of 6 weeks with the provision of influenza vaccination. The questionnaire collected demographic and other data; it included 12 questions on their general knowledge and assessed their attitude toward influenza vaccination, and their awareness of vaccine risk and the potential benefits during pregnancy. The knowledge score obtained was then calculated and compared. A total of 998 patients took part in the questionnaire with a response rate of 92%. There was poor awareness that the flu vaccine is safe to administer during pregnancy (130, 13.1%) and that all pregnant women should receive the flu vaccine (190, 19.1%). Pregnant women with flu vaccine knowledge score of ⩽5 (range 0-12) were significantly less likely to take the vaccine (OR 3.78, 95% CI 2.68-5.26, < 0.001). There was a low uptake of the vaccine (178, 18.1%) and only 29 (3.0%) had previously been offered the flu vaccine by any doctor during their pregnancy. In addition, 255 (25.8%) were against taking the flu vaccine during pregnancy. The knowledge and uptake of the influenza vaccine among Saudi pregnant women are low. One quarter was against the vaccine during pregnancy. Very few believed the flu vaccine to be safe during pregnancy. Rarely, physicians advise their clients to take flu vaccine.

Warfarin is a commonly prescribed oral anticoagulant in Saudi Arabia and yet patient adherence to warfarin therapy and its impact on anticoagulation control have not been well researched here. A cross-sectional survey was conducted over 6 weeks at the outpatient anticoagulant clinic on patients who were receiving warfarin. Adherence was assessed using the translated Arabic version of the Morisky Medication Adherence Scale (MMAS-8). Levels of adherence were classed as low (score ⩽ 7), or high (score = 8) based on the scores. Good anticoagulation control was defined as percent Time INR in Therapeutic Range (TTR) ⩾ 75% using the Rosendaal method. A total of 192 patients completed a questionnaire with a response rate of 68.1%. It was established that no association was found between adherence to warfarin therapy and INR control groups. Among the 89 (46.4%) patients who had high adherence, only 34 (38.2%) had an acceptable INR control. This was versus 103 (53.6%) patients who had low adherence but also 34 (33.0%) had good INR control. Multivariate logistic regression (MLR) analysis showed that when studying females and occupational status of unemployment, they were independently associated with poor INR control with an OR 2.31, 95% CI 1.10-4.92, and OR 2.71, 95% CI 1.12-6.61 respectively. MLR analysis also showed that age <50 years alongside no formal education was independently associated with low adherence to warfarin therapy with an OR 2.67, 95% CI 1.29-5.52 and OR 2.63, 95% CI 1.01-6.93 respectively. The demographic background influences adherence and INR control, but no association was found between adherence and anticoagulation control.

Hospital pharmacists are increasingly using electronic technologies to improve prescribing and transcribing of medications in Saudi Arabia.

ObjectivesTo determine the incidence of adverse drug events (ADEs) and assess their severity and preventability in four Saudi hospitals.DesignProspective cohort study.SettingThe 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.ParticipantsAll patients (≥12 years) admitted to the study units over 4 months.Primary and secondary outcome measuresIncidents 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.ResultsWe 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.ConclusionsWe 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.
