BACKGROUND: Sleep is often challenging for medical students because of the considerable amount of learning they have to do. The aim of this study was to identify the patterns of sleep quality and daytime sleepiness among medical students in Saudi Arabia and to identify the possible factors associated with poor quality of sleep and daytime sleepiness. MATERIALS AND METHODS: This cross-sectional questionnaire-based study was conducted at College of Medicine, Imam Abdulrahman Bin Faisal University, Saudi Arabia. The questionnaire included the prevalidated Pittsburgh Sleep Quality Index (PSQI) to measure sleep quality and the Epworth Sleepiness Scale (ESS) to measure daytime sleepiness. Covariates included sociodemographic characteristics and academic performance. Bivariate and multivariate logistic regression analyses were used to obtain adjusted and unadjusted odds ratios (ORs). RESULTS: The sampled population comprised 36.7% males and 63.30% females. The mean global PSQI score was (standard deviation (SD)=4.66), while the mean global ESS score was 8.03 (SD=4.66). Further analysis showed that 80.60% had poor sleep quality and 37.80% of the students suffered from excessive daytime sleepiness. Multivariate regression showed that poor sleep quality was significantly associated with poor academic achievement (adjusted OR = 3.33, 95% confidence interval [CI] = 1.28–8.63). Furthermore, excessive sleepiness significantly increased the odds of poor academic performance (adjusted OR = 4.58, 95% CI = 1.09–20.81). CONCLUSIONS: The results on daytime sleepiness were found to be within the ranges reported worldwide; poor sleep quality was found to be among the highest ever reported. Both sleep quality and daytime sleepiness significantly affect academic achievement.

Background: Musculoskeletal symptoms account for the majority of work-related illnesses resulting in a significant economic burden on society. Computer users are subject to unique repetitive strains that predispose them to musculoskeletal symptoms. In the digitalized field of radiology, radiologists spend long hours interpreting medical images on computers. This study aimed to determine the prevalence of musculoskeletal symptoms among radiologists in Saudi Arabia and their contributing factors. Methods: An online survey was sent to radiologists in all hospitals (academic, public and private) in the major cities of the Eastern Province of Saudi Arabia covering demographic characteristics, workload (e.g. the time spent at a computer workstation), and workstation environments including the number of monitors as well as the adjustability of the height of the workstation and the viewing distance. This survey of 263 radiologists was conducted in April 2019. It included an evaluation of musculoskeletal symptoms using the Nordic Musculoskeletal Questionnaire. The study outcome was the presence of disabling musculoskeletal symptoms in any body region, which restricted the performance of normal activities in the last 12 months. Results were analyzed descriptively using a Chi-square test and logistic regression analysis to estimate the odd ratio of experiencing disabling musculoskeletal symptoms in the last 12 months. Results: The survey was completed by 198 participants (111 men and 87 women) with a response rate of 75.3%. Most participants (71.2%) were aged below 40 years. A multivariate logistic regression analysis revealed being a female radiologist (OR = 2.7; 95% CI: 1.2–6.5), aged 30–39 years (OR = 4.1; 95% CI: 1.1–15.3), and predominantly reviewing computed tomography (CT) images (OR = 4.1; 95% CI: 1.4–12.3) or ultrasound scans (OR = 5.9; 95% CI: 1.4–25.3) were associated with higher prevalence of disabling musculoskeletal symptoms, compared to those aged below 30 years and those who reviewed various imaging modalities, respectively. Conclusions: Musculoskeletal symptoms are common among radiologists with lower back and neck pain being the most frequent complaints. Being a female radiologist, aged 30–39 years, and reviewing CT or ultrasound scans were associated with higher rates of disabling musculoskeletal symptoms.

Background: Social Anxiety disorder (SAD) is common worldwide. However, data from Saudi Arabia is deficient. This study aims to determine the prevalence of SAD across Saudi medical students and its associations with sociodemographic factors and their academic performance. Methods: The main outcome was presence/absence of SAD and the secondary outcome was its level of severity. These were assessed from the Social Phobia Inventory. Associated factors included sociodemographic variables, as well as educational characteristics of students. Descriptive statistics were reported as counts and percentages, and unadjusted and adjusted odds ratios (OR) and their 95% confidence intervals (CIs) were computed through bivariate and multivariate logistic regression. Results: Of 5896 Saudi medical students who participated in the study, the prevalence of SAD was almost 51%. While 8.21% and 4.21% had reported severe and very severe SAD, respectively. Older age students were at lower risk of developing SAD (OR = 0.92, 95% CI = 0.89 – 0.96). In contrast, females (OR = 1.13, 95% CI = 1.01 – 1.26), students enrolled in private colleges and colleges implementing non-problem-based learning (OR = 1.29, 95% CI = 1.09 – 1.52 and OR = 1.29. 95% CI = 1.15 – 1.46 respectively) were at higher risk. A significant elevated risk of SAD was found among students who had previously failed, and had a low GPA. Conclusion: SAD is prevalent among the sampled population, and different associated factors were identified. Current results could raise the awareness of faculty members and healthcare providers towards early detection and management of these cases.

Background: Pulmonary embolism (PE) is a common and life-threatening medical condition with non-specific clinical presentation. Computed tomography pulmonary angiography (CT-PA) has been the diagnostic modality of choice, but its use is not without risks. Clinical decision rules have been established for the use of diagnostic modalities for patients with suspected PE. This study aims to assess the adherence of physicians to the diagnostic algorithms and rules. Methods: A retrospective observational study examining the utilization of CT-PA in the Emergency Department of King Fahd Hospital of Imam Abdulrahman Bin Faisal University for patients with suspected PE from May 2016 to December 2019. The electronic health records were used to collect the data, including background demographic data, clinical presentation, triage vital signs, D-dimer level (if ordered), risk factors for PE, and the CT-PA findings. The Wells score and pulmonary embolism rule-out (PERC) criteria were calculated retrospectively without knowledge of the results of D-dimer and the CT-PA. Results: The study involved a total of 353 patients (125 men and 228 women) with a mean age of 46.7 ± 18.4 years. Overall, 200 patients (56.7%) were classified into the “PE unlikely” group and 153 patients (43.3%) in the “PE likely” group as per Wells criteria. Out of all the CT-PA, 119 CT-PA (33.7%) were requested without D-dimer assay (n = 114) or with normal D-dimer level (n = 5) despite being in the “PE unlikely” group. Only 49 patients had negative PERC criteria, of which three patients had PE. Conclusions: The study revealed that approximately one-third of all CT-PA requests were not adhering to the clinical decision rules with a significant underutilization of D-dimer assay in such patients. To reduce overutilization of imaging, planned interventions to promote the adherence to the current guidelines seem imperative.

Background: Anxiety disorders are a significant global health concern with destructive morbidity and mortality. Medical school is a stressful environment worldwide. This study measures the prevalence of anxiety symptoms among clinical-year medical students in Saudi Arabia. As well as to explore its association with students’ sociodemographic factors, academic performance, issues experienced by them during the study of medicine, and their perceived readiness for their future specialties. Methods: The generalized anxiety disorder (GAD-7) tool along with a sociodemographic questionnaire was distributed to 523 clinical-year medical students (fourth, fifth and sixth years) from the Imam Abdulrahman Bin Faisal University, Saudi Arabia, in this cross-sectional study. Data analysis was performed with SPSS version 23 and it included the Chi-Square or Fisher’s exact tests for bivariate analysis, and the multivariable logistic regression to account for confounders. Results: The prevalence of anxiety symptoms as measured by the GAD-7 was found to be 31.7%. Of these, 14.3% had severe symptoms. Only 4.4% students went to a healthcare professional and were diagnosed with psychiatric problems. Logistic regression analysis revealed that the odds of anxiety was higher among females and students who had perceived psychological problems. However, students’ grade point average (GPA) and perceived readiness for their future specialty were not statistically significant with anxiety symptoms. Conclusion: Anxiety was highly prevalent among clinical-year medical students included in this study. This urges periodic mental health screening, proper diagnosis of high-risk individuals in medical schools, and early interventions through confidential access to mental health services.
