Design Systematic review. Data source Six international databases were searched for publications between 1 January 2006 and 31 December 2015. Data extraction and analysis Two researchers independently extracted data from eligible studies and assessed the quality of these using established instruments. Synthesis of data was informed by an appreciation of the medicines’ management process and the conceptual framework from the International Classification for Patient Safety. Results 60 studies met the inclusion criteria, of which 53 studies focused on medication errors, 3 on error-related adverse events and 4 on risk factors only. The prevalence of prescribing errors was reported in 46 studies: prevalence estimates ranged widely from 2% to 94%. Inappropriate prescribing was the most common type of error reported. Only one study reported the prevalence of monitoring errors, finding that incomplete therapeutic/safety laboratory-test monitoring occurred in 73% of patients. The incidence of preventable adverse drug events (ADEs) was estimated as 15/1000 person-years, the prevalence of drug–drug interaction-related adverse drug reactions as 7% and the prevalence of preventable ADE as 0.4%. A number of patient, healthcare professional and medication-related risk factors were identified, including the number of medications used by the patient, increased patient age, the number of comorbidities, use of anticoagulants, cases where more than one physician was involved in patients’ care and care being provided by family physicians/general practitioners. Conclusion A very wide variation in the medication error and error-related adverse events rates is reported in the studies, this reflecting heterogeneity in the populations studied, study designs employed and outcomes evaluated. This review has identified important limitations and discrepancies in the methodologies used and gaps in the literature on the epidemiology and outcomes of medication errors in community settings.Peer reviewe

Views, experiences and contributory factors related to medication errors associated with direct oral anticoagulants:a qualitative study with physicians and nurses

BACKGROUND: Direct oral anticoagulants (DOACs) have become preferable for the management of thromboembolic events. Recent publications have however identified high volume of medication errors related to DOACs. There is limited literature on why and how such errors occur or happen in clinical practice. AIM: This study aimed to explore views, experiences, contributory factors related to DOACs medication errors from the perspectives of healthcare professionals. METHOD: Semi-structured interviews using online videoconferencing were conducted with physicians and nurses from tertiary care hospitals in three different regions in Saudi Arabia. Questions included views, experiences and perceived factors contributing to errors. Interviews were transcribed verbatim and were thematically analyzed using MAXQDA Analytics Pro 2020 (VERBI Software). RESULTS: The semi-structured interviews (n = 34) included physicians (n = 20) and nurses (n = 14) until data saturation was achieved. The analysis identified five themes: Factors related to healthcare professionals (e.g. knowledge, confidence and access to guidelines); Factors related to patients (e.g. comorbidity, polypharmacy, medication review, and communication barriers); Factors related to organization (e.g. guidelines, safety culture and incidents reporting system); Factors related to the DOACs medications (e.g. lack of availability of antidotes and dosing issues); and Strategies for error prevention/mitigation (e.g. the need for professional training and routine medication review). CONCLUSION: Healthcare professionals identified errors in relation to DOACs as multifactorial including their own and patient lack of knowledge, lack of clinical guidelines and organizational factors including safety culture. Medication review and reconciliation on discharge were key strategies suggested to reduce DOACs related errors. These strategies support the role of pharmacists as direct patients care providers to minimize DOACs errors.

Factors impeding the supply of over-the-counter medications according to evidence-based practice: A mixed-methods study.

ObjectiveDespite the positive attitudes pharmacists have toward evidence-based practices (EBPs), its application in community pharmacies in Saudi Arabia is lacking. Therefore, this study aimed to explore and assess EBPs by community pharmacists in Saudi Arabia when they dispense over-the-counter (OTC) medications for three minor ailments: diarrhea, cough, and the common cold.Research design and methodsWe used a mixed-methods approach consisting of two study parts. The first was a quantitative investigation that used mystery shoppers. Four researchers, posing as mystery shoppers, visited 214 randomly selected pharmacies in the Riyadh region of Saudi Arabia. They used 14 questions from a standardized checklist to examine EBPs by community pharmacists. The qualitative part of the study entailed three focus-group discussions with 13 pharmacists from different community practice settings and explored factors that affected the application of EBPs when supplying OTC medications from the pharmacists' point of view.ResultsThe analysis indicated that 40% of pharmacists dispensed OTC medications according to EBPs. Logistic regression analysis showed that one question, "Describe your symptoms", predicted the correct supply of OTC medications (p = 0.021). The qualitative section of the study identified nine factors that affected EBP. Some of these factors facilitated EBP, such as established patient-pharmacist relationships, some acted as barriers such as conflicts between available evidence, while other factors could either facilitate or hinder EBPs, such as the health literacy of the patient.ConclusionGiven that dispensing OTC medication is a core function of pharmacists, this study uncovered low adherence to EBPs by community pharmacists in Saudi Arabia when dispensing OTC medication for three minor ailments: diarrhea, cough, and the common cold. Furthermore, this study identified a number of explanatory factors for this low adherence. Targeting these factors could help change the behavior of pharmacists and decrease undesirable outcomes

Cardiovascular Disease Risk Prevention Services by Pharmacists in Saudi Arabia: What Do Policymakers and Opinion Leaders Think?

Background: Cardiovascular disease (CVD) is an emerging contributor to national morbidity and mortality in Saudi Arabia. CVD risk prevention services are limited, particularly with an over-utilised public health sector and an under-utilised and under-resourced primary care sector. Globally, there is evidence that community pharmacists can play a key role in CVD prevention within primary care. However, the perspectives of policymakers and opinion leaders are critical to successful translation of evidence into practice. Thus, the aim was to engage policymakers and professional leaders in discussions about implementing high-quality CVD risk prevention services in community pharmacy. Methods: Qualitative semi-structured interviews were conducted, audio-recorded and transcribed verbatim. All transcripts were thematically analysed. Results: A total of 23 participants (87% male) from government and non-government sectors were interviewed. Of these, almost 65% had pharmacy qualifications. Limited provision of CVD risks preventative services in primary care was acknowledged. However, most participants favoured the concept of utilising community pharmacist’s capacity to assist in preventive health services. The data yielded four key themes: 1) Future pharmacy CVD health service models, 2) Demonstrable outcomes, 3) Professional engagement and advocacy and 4) Implementability. CVD health services roles (health screening, primary and secondary prevention services), pragmatic factors and tiered models of care (minimal, medium and comprehensive pharmacist involvement) were discussed. The need for humanistic, clinical and cost effectiveness outcomes and activation of professional bodies were deemed important. Professional pharmacy governance to develop pharmacy careers and workforce, pharmacy curricular reform and ongoing education were posed as key success factors for pharmacy roles. Practice policies, standards and guidelines were seen as required to adhere to stringent quality control for future pharmacy services provision. Participants implementation vision for such services included scalability, affordability, access, adoption and health system reform. Most discussion focused on the need for structural improvement with limited input regarding processes or outcomes required to establish such models. Conclusions: Most participants favoured pharmacy-based CVD risk prevention services, despite the variability in proposed service models. However, prior to developing such services, support structures at the health system and health professional level are needed as well as building public support and acceptability for pharmacy services

Patients’ views and experiences on the use and safety of directly acting oral anticoagulants: a qualitative study

Abstract Background Direct oral anticoagulants (DOACs) are considered high-risk medications and used to prevent thromboembolic events and stroke. This study aimed to examine patients’ views and experiences of DOACs use and factors that can promote safety associated with DOACs. Methods In-depth interviews were conducted with adult patients who had been prescribed DOACs, identified and invited by local collaborators in three different tertiary care hospitals in Saudi Arabia. A topic guide developed based on was used to inform the interview. Data were analysed thematically. Results Data saturation was achieved by the ninth participants. Three major themes were identified: (1) factors affecting DOAC's safety from the patients view; (2) barriers to adherence to DOACs and (3) strategies to promote the safety of DOACs. Lack of knowledge of DOACs, using inappropriate sources of information, lack of communication with HCPs, difficulty in having access to DOACs and lack of monitoring were the main factors affecting the safe use of DOACs. Unavailability of the drugs and difficulty in timely getting to hospitals affected adherence. Patients acknowledged difficulties communicating with healthcare professionals, timely access to anticoagulation clinics and in obtaining their DOACs on time. Conclusions There is a need to develop and evaluate theory-based interventions to promote patient knowledge, understanding and shared decision-making to optimise DOACs use and improve their safety

Early identification of pneumonia patients at increased risk of Middle East respiratory syndrome coronavirus infection in Saudi Arabia

Background: The rapid and accurate identification of individuals who are at high risk of Middle East respiratory syndrome coronavirus (MERS-CoV) infection remains a major challenge for the medical and scientific communities. The aim of this study was to develop and validate a risk prediction model for the screening of suspected cases of MERS-CoV infection in patients who have developed pneumonia. Methods: A two-center, retrospective case–control study was performed. A total of 360 patients with confirmed pneumonia who were evaluated for MERS-CoV infection by real-time reverse transcription polymerase chain reaction (rRT-PCR) between September 1, 2012 and June 1, 2016 at King Abdulaziz Medical City in Riyadh and King Fahad General Hospital in Jeddah, were included. According to the rRT-PCR results, 135 patients were positive for MERS-CoV and 225 were negative. Demographic characteristics, clinical presentations, and radiological and laboratory findings were collected for each subject. Results: A risk prediction model to identify pneumonia patients at increased risk of MERS-CoV was developed. The model included male sex, contact with a sick patient or camel, diabetes, severe illness, low white blood cell (WBC) count, low alanine aminotransferase (ALT), and high aspartate aminotransferase (AST). The model performed well in predicting MERS-CoV infection (area under the receiver operating characteristics curves (AUC) 0.8162), on internal validation (AUC 0.8037), and on a goodness-of-fit test (p = 0.592). The risk prediction model, which produced an optimal probability cut-off of 0.33, had a sensitivity of 0.716 and specificity of 0.783. Conclusions: This study provides a simple, practical, and valid algorithm to identify pneumonia patients at increased risk of MERS-CoV infection. This risk prediction model could be useful for the early identification of patients at the highest risk of MERS-CoV infection. Further validation of the prediction model on a large prospective cohort of representative patients with pneumonia is necessary.
