INTRODUCTION: The prevalence of cirrhosis is increasing despite advances in therapeutics, and it remains an expensive medical condition. Studies examining the healthcare burden of inpatient cirrhosis-related care regardless of etiology, stage, or severity are lacking. This study aims to describe the current drivers of cost, length of stay (LOS), and mortality in hospitalized patients with cirrhosis. METHODS: Using the National Inpatient Sample (NIS) data from 2008 to 2014, we categorized admissions into decompensated cirrhosis (DC), compensated cirrhosis (CC), and NIS without cirrhosis. Descriptive statistics and regression analysis were used to analyze the association between patient characteristics, comorbidities, complications, and procedures with costs, LOS, and mortality in each group. RESULTS: The hospitalization costs for patients with cirrhosis increased 30.2% from 2008 to 2014 to $7.37 billion. Cirrhosis admissions increased by 36% and 24% in the DC and CC groups, respectively, compared with 7.7% decrease in the NIS without cirrhosis group. DC admissions contributed to 58.6% of total cirrhotic admissions by 2014. Procedures increased costs in both DC and CC groups by 15%–152%, with mechanical ventilation being associated with high cost increase and mortality increase. Complications are also key drivers of costs and LOS, with renal and infectious complications being associated with the highest increases in the DC group and infections and nonportal hypertensive gastrointestinal bleeding for the CC group. DISCUSSION: Economic burden of hospitalized patients with cirrhosis is increasing with more admissions and longer LOS in DC and CC groups. Important drivers include procedures and portal hypertensive and nonportal hypertensive complications.

The clinical presentation of COVID‐19 due to infection with SARS‐CoV‐2 is highly variable with the majority of patients having mild symptoms while others develop severe respiratory failure. The reason for this variability is unclear but is in critical need of investigation. Some COVID‐19 patients have been labelled with ‘happy hypoxia’, in which patient complaints of dyspnoea and observable signs of respiratory distress are reported to be absent. Based on ongoing debate, we highlight key respiratory and neurological components that could underlie variation in the presentation of silent hypoxaemia and define priorities for subsequent investigation.

Background: Evaluation and interpretation of the literature on obstructive sleep apnea (OSA) allows for consolidation and determination of the key factors important for clinical management of the adult OSA patient. Toward this goal, an international collaborative of multidisciplinary experts in sleep apnea evaluation and treatment have produced the International Consensus statement on Obstructive Sleep Apnea (ICS:OSA). Methods: Using previously defined methodology, focal topics in OSA were assigned as literature review (LR), evidence-based review (EBR), or evidencebased review with recommendations (EBR-R) formats. Each topic incorporated the available and relevant evidence which was summarized and graded on study quality. Each topic and section underwent iterative review and the ICS:OSA was created and reviewed by all authors for consensus. Results: The ICS:OSA addresses OSA syndrome definitions, pathophysiology, epidemiology, risk factors for disease, screening methods, diagnostic testing types, multiple treatment modalities, and effects of OSA treatment on multiple OSA-associated comorbidities. Specific focus on outcomes with positive airway pressure (PAP) and surgical treatments were evaluated. Conclusion:This review of the literature consolidates the available knowledge and identifies the limitations of the current evidence on OSA. This effort aims to create a resource for OSA evidence-based practice and identify future research needs. Knowledge gaps and research opportunities include improving the metrics of OSA disease, determining the optimal OSA screening paradigms, developing strategies for PAP adherence and longitudinal care, enhancing selection of PAP alternatives and surgery, understanding health risk outcomes, and translating evidence into individualized approaches to therapy.
