Simulation-based education (SBE) is a fundamental teaching method that complements traditional teaching modalities. SBE has improved students’ knowledge, understanding, and numerous essential skills within undergraduate pharmacy education, similar to traditional teaching methods. However, SBE has become crucial for developing students’ teamwork, decision-making, and communication skills. Even though the Accreditation Council for Pharmacy Education (ACPE) has acknowledged the benefit of SBE in interprofessional education (IPE) and the introductory pharmacy practice experience (IPPE). This article provides evidence that SBE can be effective beyond that. This narrative review is focused on the literature related to SBE modalities and the assessment methods of student learning outcomes in the undergraduate pharmacy curriculum. The review illustrates that SBE is an effective teaching method that could be utilized within the pharmacy curriculum. The review also could help pharmacy educators decide on the best modality and placement of integrating patient simulation within the pharmacy curriculum. Combining multiple simulation techniques may be the best way to achieve the desired student learning outcomes.

Lack of knowledge among healthcare workers (HCWs) about infectious diseases leads to delayed diagnosis of new cases, spread of infection, and poor infection control practices. Therefore, HCWs based in hospitals must be equipped with good knowledge about the pathogen and disease to put up a robust fight against the virus. The aim of this study was to assess knowledge, attitude, and practices (KAP) of HCWs about coronavirus disease 2019 (COVID-19) at multiple public and private hospitals in Riyadh, Saudi Arabia. A cross-sectional, online questionnaire-based study was conducted between July and August of 2020. Logistic regression was used to investigate differences in the level of KAP among different participants. A total of 510 HCWs in hospitals completed the questionnaire. Only two-thirds of the participants (67.8%) had adequate knowledge about COVID-19, 72.2% of the participants had a positive attitude toward COVID-19, and 80.2% of the participants were practicing appropriately most of the time. Poor KAP was associated with a low education level. The females had better knowledge and attitude, whereas the males were more likely to practice appropriately most of the time. Notably, the participants from the nursing profession demonstrated a less favorable attitude compared with medical staff from other professions, but that did not prevent them from being the best when it comes to applying appropriate practices. The inadequate level of KAP among HCWs with the continuation of the pandemic and the possibility of a second wave demonstrates the need for continuous COVID-19-specific infection control training and emotional well-being supporting programs, especially for HCWs with a low education level.

Background: Despite the empirical literature demonstrating the efficacy of antidepressant medications for treatment of depression disorder, these medications’ effect on patients’ overall well-being and health-related quality of life (HRQoL) remains controversial. This study investigates the effect of antidepressant medication use on patient-reported HRQoL for patients who have depression. Methods: A comparative cohort, secondary database analysis was conducted using data from the United States’ Medical Expenditures Panel Survey for patients who had depression. HRQoL was measured using the SF-12 and reported as physical and mental component summaries (PCS and MCS). A cohort of patients that used antidepressant medications were compared to a cohort of patients that did not. Univariate and multivariate difference-in-differences (D-I-D) analyses were used to assess the significance of the mean difference of change on the PCS and MCS from baseline to follow-up. Results: On average, 17.5 million adults were diagnosed with depression disorder each year during the period 2005–2016. The majority were female (67.9%), a larger proportion of whom received antidepressant medications (60.5% vs. 51.5% of males). Although use of antidepressants was associated with some improvement on the MCS, D-I-D univariate analysis revealed no significant difference between the two cohorts in PCS (–0.35 vs. –0.34, p = 0.9595) or MCS (1.28 vs. 1.13, p = 0.6405). The multivariate D-I-D analyses ensured the robustness of these results. Conclusion: The real-world effect of using antidepressant medications does not continue to improve patients’ HRQoL over time. Future studies should not only focus on the short-term effect of pharmacotherapy, it should rather investigate the long-term impact of pharmacological and non-pharmacological interventions on these patients’ HRQoL.

The use of traditional medicinal plants in Saudi Arabia stems mainly from consumers’ belief in prophetic medicine. This study was conducted to explore changes in patients’ use of dietary or herbal supplements among individuals infected with COVID-19 before and during infection and the association between herbal or dietary supplements and hospitalization. A cross-sectional, questionnaire-based study was conducted enrolling symptomatic patients who had recently recovered from COVID-19. Data were collected through phone interviews, and McNemar’s test was used to investigate changes to consumption of dietary or herbal supplements before and during infection. Multivariable logistic regression was used to investigate the association between supplements use during patients’ infection and hospitalization. A total of 738 patients were included in this study, of whom 32.1% required hospitalization. About 57% of participants were male with a mean age of 36.5 (±11.9) years. The use of lemon/orange, honey, ginger, vitamin C, and black seed among participants significantly increased during their infection. In contrast, patients using anise, peppermint, and coffee peel before their infection were more likely to stop using them during their infection. In addition, using lemon/orange (p < 0.0001), honey (p = 0.0002), ginger (p = 0.0053), vitamin C (p = 0.0006), black seed (p < 0.0001), peppermint (p = 0.0027), costus (p = 0.0095), and turmeric (p = 0.0012) was significantly higher among nonhospitalized patients than hospitalized ones. However, in the multivariable logistic regression, only use of vitamin C (OR = 0.51; 95% CI 0.33–0.79), peppermint (OR = 0.53; 95% CI 0.31–0.90), and lemon/orange (OR = 0.54; 95% CI 0.33–0.88) was associated with significantly lower odds of hospitalization. The study reveals that patients’ consumption of dietary or herbal supplements changed in response to their COVID-19 infection, with hospitalized patients having a lower likelihood of using these supplements. Because some supplements were associated with lower odds of hospitalization, these supplements or their bioactive components should be further investigated as feasible options for COVID-19 treatment.

This was a questionnaire-based cross-sectional study that explored the impact of the COVID-19 pandemic on the availability of essential medicine and personal protective equipment (PPE) in Saudi Arabia. Purposive sampling technique was used to recruit individuals working in the supply chain departments in different healthcare sectors in Saudi Arabia. One hundred and three pharmaceutical and medical supply chain employees participated in the study. Most of the participants (58.3%) were aged ≥35 years, male (65%), and pharmacists (92.2%). The majority of participants had at least two years of experience in supply chain (77.6%), worked in public hospitals (95.15%), and were mostly working at healthcare institutions located in Riyadh province (59.2%). Approximately 51% of the participants reported shortages of 10 or more essential drugs. Tocilizumab, hydroxychloroquine, lopinavir/ritonavir, ribavirin, dexamethasone, enoxaparin, interferon beta-1b, cisatracurium besylate, prednisolone, hydrocortisone, methimazole, and methylprednisolone were reported to be in shortage by at least 8% of the participants. Almost 70% of the participants reported that the pandemic did not significantly impact the prices of prescription drugs in shortage (e.g., ≥25%). Moreover, about 70% of the participants reported direct purchasing or procurement of drugs in shortage. Surgical masks, face shields, medical gowns, and N95 respirators were reported to be in short supply by 33% or more of the participants. Approximately 53% of the participants reported the prices of PPE in shortage had seen an increase by at least 25% during the pandemic. Although the COVID-19 pandemic has caused a significant disruption in the global pharmaceutical supply chain, its impact was largely manageable in Saudi healthcare institutions. This can be attributable to multiple reasons such as the effective exchange programs between hospitals and the drastic increase in public healthcare spending to ameliorate the negative impact of the pandemic on the healthcare sector.
