Full adherence to cirrhosis quality indicators is associated with lower mortality in acute variceal bleeding: Nationwide audit.

BACKGROUND AND AIMS: Acute variceal bleeding (AVB) is a major complication in patients with cirrhosis. Using a nationwide AVB audit, we performed a nested cohort study to determine whether full adherence to the AVB quality indicator (QI) improves clinical outcomes in patients with cirrhosis and AVB. APPROACH AND RESULTS: We assessed real-world adherence to AVB QI among patients with cirrhosis admitted for AVB in all public hospitals in Singapore between January 2015 and December 2020. Full adherence was considered when all 5 QIs were fulfilled: prophylactic antibiotics, vasoactive agents, timely endoscopy, endoscopic hemostasis during index endoscopy, and nonselective beta-blockers after AVB. We compare 6-week mortality between the full adherence and suboptimal adherence groups using a propensity-matched cohort.A total of 989 patients with AVB were included. Full adherence to all AVB QI was suboptimal (56.5%). Analysis of the propensity-matched cohort with comparable baseline characteristics showed that full adherence was associated with a lower risk of early infection (20.0% vs. 26.9%), early rebleeding (5.2% vs. 10.2%), and mortality at 6 weeks (8.2% vs. 19.7%) and 1 year (21.3% vs. 35.4%) ( p <0.05 for all). While full adherence was associated with a lower 6-week mortality regardless of the MELD score, nonadherence was associated with a higher 6-week mortality despite a lower predicted risk of 6-week mortality. Despite high adherence to the recommended process measures, patients with CTP-C remain at a higher risk of rebleeding, 6-week and 1-year mortality. CONCLUSIONS: Full adherence to the AVB QI should be the target for quality improvement in patients with cirrhosis.

Association between well-being and compliance with COVID-19 preventive measures by healthcare professionals: A cross-sectional study.

IMPORTANCE: Knowledge and attitude influence compliance and individuals' practices. The risk and protective factors associated with high compliance to these preventive measures are critical to enhancing pandemic preparedness. OBJECTIVE: This survey aims to assess differences in mental health, knowledge, attitudes, and practices (KAP) of preventive measures for COVID-19 amongst healthcare professionals (HCP) and non-healthcare professionals. DESIGN: Multi-national cross-sectional study was carried out using electronic surveys between May-June 2020. SETTING: Multi-national survey was distributed across 36 countries through social media, word-of-mouth, and electronic mail. PARTICIPANTS: Participants ≥21 years working in healthcare and non-healthcare related professions. MAIN OUTCOME: Risk factors determining the difference in KAP towards personal hygiene and social distancing measures during COVID-19 amongst HCP and non-HCP. RESULTS: HCP were significantly more knowledgeable on personal hygiene (AdjOR 1.45, 95% CI -1.14 to 1.83) and social distancing (AdjOR 1.31, 95% CI -1.06 to 1.61) compared to non-HCP. They were more likely to have a positive attitude towards personal hygiene and 1.5 times more willing to participate in the contact tracing app. There was high compliance towards personal hygiene and social distancing measures amongst HCP. HCP with high compliance were 1.8 times more likely to flourish and more likely to have a high sense of emotional (AdjOR 1.94, 95% CI (1.44 to 2.61), social (AdjOR 2.07, 95% CI -1.55 to 2.78), and psychological (AdjOR 2.13, 95% CI (1.59-2.85) well-being. CONCLUSION AND RELEVANCE: While healthcare professionals were more knowledgeable, had more positive attitudes, their higher sense of total well-being was seen to be more critical to enhance compliance. Therefore, focusing on the well-being of the general population would help to enhance their compliance towards the preventive measures for COVID-19.

Zolpidem as a Sleep Aid for Military Aviators.

INTRODUCTION: Zolpidem is a short-acting nonbenzodiazepine hypnotic that has been approved by the Republic of Singapore Air Force (RSAF) for aircrew sleep management since 2005. Prior to consuming zolpidem for operational reasons, each RSAF aircrew member is required to undergo a ground test to exclude operationally relevant adverse drug effects. This study describes the RSAF's zolpidem ground testing outcomes over a 12.5-yr period. METHODS: This is a retrospective case series of 578 RSAF aircrew members who underwent zolpidem test dosing from 1 January 2005 to 30 June 2017. RESULTS: The median age was 29 yr (range, 19-54 yr) and the mean age was 30.1 yr ± 6.3 yr. Of the aircrew members, 568 (98.3%) were men and all were of Asian origin; 558 (96.5%) were medically cleared for the operational use of zolpidem. Among the 20 (3.5%) who failed zolpidem ground testing, next-day drowsiness (cumulative incidence, 1.04%), headache (cumulative incidence, 0.87%), and dizziness (cumulative incidence, 0.35%) were the most common causes of failure. None of the aircrew members reported abnormal sleep behaviors or major adverse drug events from zolpidem ingestion. DISCUSSION: Our results suggest a low occurrence of adverse effects among military aircrew members who undergo zolpidem test dosing prior to using the drug operationally. To our knowledge, this is the single largest published case series of zolpidem ground testing outcomes among Asian military aviators.Kew GS, See B. Zolpidem as a sleep aid for military aviators.
