Objective:Emergency departments (EDs) are characterized by simultaneous care of multiple patients with various medical conditions. Due to a large number of patients with complex diseases, speed and complexity of medication use, working in under-staffing and crowded environment, medication errors are commonly perpetrated by emergency care providers. This study was designed to evaluate the incidence of medication errors among patients attending to an ED in a teaching hospital in Iran.Methods:In this cross-sectional study, a total of 500 patients attending to ED were randomly assessed for incidence and types of medication errors. Some factors related to medication errors such as working shift, weekdays and schedule of the educational program of trainee were also evaluated.Findings:Nearly, 22% of patients experienced at least one medication error. The rate of medication errors were 0.41 errors per patient and 0.16 errors per ordered medication. The frequency of medication errors was higher in men, middle age patients, first weekdays, night-time work schedules and the first semester of educational year of new junior emergency medicine residents. More than 60% of errors were prescription errors by physicians and the remaining were transcription or administration errors by nurses. More than 35% of the prescribing errors happened during the selection of drug dose and frequency. The most common medication errors by nurses during the administration were omission error (16.2%) followed by unauthorized drug (6.4%). Most of the medication errors happened for anticoagulants and thrombolytics (41.2%) followed by antimicrobial agents (37.7%) and insulin (7.4%).Conclusion:In this study, at least one-fifth of the patients attending to ED experienced medication errors resulting from multiple factors. More common prescription errors happened during ordering drug dose and frequency. More common administration errors included dug omission or unauthorized drug.

Objective: The detection of pulmonary embolism in emergency department requires an urgent therapeutic and diagnostic attention. This study was performed to determine the accuracy and efficacy of ultrasound in the diagnosis of pulmonary embolism. Methods: In this study, 110 patients who referred to the emergency department with traumatic embolism symptoms were enrolled. All the patients underwent computed tomography (CT) angiography. Patients were divided into positive and negative outcomes according to the results of transthoracic ultrasonography and CT angiography. Results: In this study, 110 patients were enrolled, of whom 52 (47.3%) were male and 58 (52.7%) were female. Among the patients, 100 (90.9%) patients presented with dyspnea, whereas the frequency of pleural pain was 27% (24.5%). Sensitivity, specificity, positive predictive value, and negative predictive value for ultrasound were 45.67%, 77.41%, 88.09%, and 35.29%, respectively. The positive outcomes from CT scan were significantly associated with gender, p = 0.005. The gender and transthoracic ultrasonography outcomes were also significantly correlated, p = 0.019, and the outcomes of ultrasound were significantly different from those of CT scan, p = 0.008. Conclusion:Transthoracic ultrasonography may be used to diagnose pulmonary embolism as a technique in the emergency department, especially in patients who are unable to move due to the severity of the disease. However, further comparative studies are required in this aspect.

BackgroundCaring for patients with cancer can result in significant burden, anxiety, and depression among family caregivers, leading to alterations in their mental and physical wellbeing. Evidence on the level of cancer caregivers' burden, depression, anxiety, their role in assisting their patients, and other patient and caregiver factors that play in improving/worsening the outcomes, is limited. This study explored the prevalence of caregiving burden, depression, and anxiety with a focus on the patient and caregiver-related factors among cancer family caregivers.MethodsA cross-sectional study was conducted on the population of caregivers of adult patients with cancer in Zanjan, Iran between 2019 and 2020. The Beck Depression Inventory (BDI), the Beck Anxiety Inventory (BAI), and the Zarit Burden Inventory (ZBI) were used to measure outcome variables. Clinical and basic characteristics of the caregivers and patients were also collected. An independent samples t-test, analysis of variance, Pearson's correlation coefficient, and stepwise linear regression were performed using SPSS software version 26.ResultsMean ± standard deviation age of the caregivers (167 men and 133 women) was 40.77 ± 12.56. Of the caregivers, 46.3, 53, and 30.7% showed severe depression, anxiety, and burden, respectively. There was a significant positive correlation between ZBI with both BDI [r(298) = 0.19, p < 0.01] and BAI [r(298) = 0.20, p < 0.01]. Caregiving ≥24 months (B = 14.36, p < 0.001), outpatient care setting (B = −12.90, p < 0.001), being retired (B = −12.90, p < 0.001), depression (B = 0.28, p < 0.001), supplemental health insurance (B = −7.79, p < 0.001), being illiterate (B = 7.77, p < 0.01), surgery (B = 8.55, p < 0.01), ECOG1 (B = 4.88, p < 0.01), and patient's age (B = 0.11, p < 0.05) were found to be significant predictors of caregiving burden.ConclusionHigh levels of depression, anxiety, and burden were observed among the caregivers of patients with cancer. These findings underline the importance of paying close attention to the needs and psychological challenges of this population.

Background Neck pain and disability is a significant public health problem with only very few evidence-based treatment option. The aim of this study was to evaluate the effect of isometric exercise on pain and disability of cervical spondylosis. Methods Twenty four patients with cervical osteoarthritis and neck pain (22 females and 2 males; mean age, 46.70 ± 13.71 years) were recruited and randomly allocated into 2 arms: neck isometric exercises (n = 12) and conservative management without exercise (n = 12). The Neck Disability Index (NDI) and Neck Pain and Disability Scale (NPAD) were used to assess participants at baseline and after 4 weeks. Results Basic characteristics, NDI score and NPAD score were not significantly different between groups at baseline. The exercise arm demonstrated significantly lower scores regarding NDI (mean, 17.41 vs. 25.58; P-value = 0.035) and NPAD (mean, 25.33 vs. 66.67; P < 0.001), compared to the control arm after 4 weeks. The exercise arm also showed significant within group reduction considering NDI and NPAD scores after 4 weeks (Both, P < 0.001). Conclusion Our findings suggested that isometric exercises might be a beneficial treatment for improving pain and disability caused by cervical spondylosis.

Objective: Due to the presence of pain during nasogastric tube (NGT) insertion and related complications and lack of positive clinical response of nasopharyngeal anesthesia with lidocaine and the related side effects and limitations in ketamine and intravenous midazolam, this study aims to determine the efficacy of oral midazolam in relieving pain in the patients requiring NGT insertion. Methods: A randomized, triple-blind clinical trial was performed on the patients in the Emergency Department of Zanjan Valiasr and Mousavi Hospitals in Iran, who were nominated for NGT. In each group, 100 patients were examined. Two milligram syrups of midazolam and placebo were administered 20 min before the procedure. In two groups, the pain based on the Visual Analog Scale and satisfaction rate of patients during the NGT insertion were compared. The data were analyzed through the SPSS software version 16.0. Findings: There was no statistically significant difference in the demographic characteristics of two groups. Despite the effects of potential confounding variables, the cause of the referral and indication of NGT, as well as the use of midazolam syrup, had a significant relationship with the outcome, so that midazolam group experienced less pain. The mean and standard deviation of the examined outcomes (feeling of pain and satisfaction with NGT insertion) was statistically significantly different in the midazolam group as compared to the placebo group ( P = 0.001). Conclusion: Midazolam was effective in decreasing pain and increasing the satisfaction of patients after NGT insertion. This manuscript is registered in Irct. com with code IRCT20110629006922N4.
