Benzodiazepine use disorder: A cross-sectional study at a tertiary care center in Lebanon.

Benzodiazepines are medications used for the treatment of multiple conditions including anxiety disorders, insomnia, agitation, and seizures. They are the most prescribed psychiatric medications and the third most misused drugs among adults and adolescents in the US. This study aims to assess the patient utilization patterns and benzodiazepine use disorder among Lebanese patients. A cross-sectional study was performed on Lebanese patients presenting to the Emergency Department of the American University of Beirut Medical Center (AUBMC), between November 11th, 2019, and May 30th, 2020. Institutional review board approved the study, and an informed consent was obtained from patients. A total of 244 patients were included in the final analysis. A total of 154 (63.1%) patients were found to have benzodiazepine use disorder as per the DSM-V criteria with the majority (64%) being females and young adults aged 18 to 40 years. The most common medication was alprazolam, and anxiety was the most common reason for benzodiazepine use. The majority (88%) of patients obtained their medications using a physician's prescription. More than half of users were not satisfied with the physician's instructions and lacked knowledge about side effects and abuse potential. The high rate of benzodiazepine misuse among our young adults highlights an important public health concern that requires interventions and policy implementation.

Clinical characteristics and outcomes of bone marrow transplantation patients presenting to the ED of a tertiary care center.

BACKGROUND: Bone marrow transplantation is a breakthrough in the world of hematology and oncology. In our region, there is scarce literature studying emergency department visits among BMT patients, as well as their predictors of mortality. OBJECTIVES: This study aimed to assess the frequency, reasons, clinical characteristics and outcomes of patients presenting to the ED after a BMT, and to study the predictors of mortality in those patients. This study also compares those variables among the different types of BMT. METHODS: This was a retrospective cohort study conducted on all adult patients who have completed a successful BMT and visited the ED. RESULTS: Our study included 115 BMT patients, of whom 17.4% died. Those who died had a higher median number of ED visits than those who did not die. Around 36.5% presented with fever/chills with 29.6% diagnosed with pneumonia on discharge. We found that the odds of mortality were significantly higher among those who presented with dyspnea (p < .0005) and AMS (p = .023), among septic patients (p = .001), those who have undergone allogeneic BMT (p = .037), and those who were admitted to the ICU (p = .002). Moreover, the odds of mortality were significantly higher among hypotensive (p ≤0005) and tachycardic patients (p = .015). CONCLUSION: In our study, we have shown that BMT patients visit the ED very frequently and have high risk of in-hospital mortality. Moreover, our study showed a significant association between mortality and patients with dyspnea, AMS, sepsis, allogeneic BMT type, ICU admission, hypotension and tachycardia.
