RESUMO
INTRODUCTION: Coronavirus disease 2019 (COVID-19) has multiorgan involvement and its severity varies with the presence of pre-existing risk factors like cardiovascular disease (CVD) and hypertension (HTN). Therefore, it is important to evaluate their effect on outcomes of COVID-19 patients. The objective of this meta-analysis and meta-regression is to evaluate outcomes of COVID-19 amongst patients with CVD and HTN. METHODS: English full-text observational studies having data on epidemiological characteristics of patients with COVID-19 were identified searching PubMed from December 1, 2019, to July 31, 2020, following Meta-analysis Of Observational Studies in Epidemiology (MOOSE) protocol. Studies having pre-existing CVD and HTN data that described outcomes including mortality and invasive mechanical ventilation (IMV) utilization were selected. Using random-effects models, risk of composite poor outcomes (meta-analysis) and isolated mortality and IMV utilization (meta-regression) were evaluated. Pooled prevalence of CVD and HTN, correlation coefficient (r) and odds ratio (OR) were estimated. The forest plots and correlation plots were created using random-effects models. RESULTS: Out of 29 studies (n=27,950) that met the criteria, 28 and 27 studies had data on CVD and HTN, respectively. Pooled prevalence of CVD was 18.2% and HTN was 32.7%. In meta-analysis, CVD (OR: 3.36; 95% CI: 2.29-4.94) and HTN (OR: 1.94; 95% CI: 1.57-2.40) were associated with composite poor outcome. In age-adjusted meta-regression, pre-existing CVD was having significantly higher correlation of IMV utilization (r: 0.28; OR: 1.3; 95% CI: 1.1-1.6) without having any association with mortality (r: -0.01; OR: 0.9; 95% CI: 0.9-1.1) among COVID-19 hospitalizations. HTN was neither correlated with higher IMV utilization (r: 0.01; OR: 1.0; 95% CI: 0.9-1.1) nor correlated with higher mortality (r: 0.001; OR: 1.0; 95% CI: 0.9-1.1). CONCLUSION: In age-adjusted analysis, though we identified pre-existing CVD as a risk factor for higher utilization of mechanical ventilation, pre-existing CVD and HTN had no independent role in increasing mortality.
RESUMO
Background Acute pancreatitis is a sudden inflammation of the pancreas, and biliary pancreatitis remains the most common cause of acute pancreatitis. Endoscopic retrograde cholangiopancreatography (ERCP) is both a diagnostic and therapeutic invasive procedure to evaluate and treat pancreaticobiliary system diseases. ERCP is very commonly used in acute pancreatitis with coexisting acute cholangitis or biliary obstruction. There was a need for a nationwide study to evaluate ERCP utilization trends and health-care costs among acute pancreatitis patients. Aim We sought to determine the prevalence trend, hospitalization cost and stay, and predictors of utilization of ERCP amongst patients with acute pancreatitis. Methods We performed a population-based retrospective analysis of national data in adult acute pancreatitis hospitalizations. We evaluated the characteristics of the ERCP cohort, prevalence trend, and hospital utilization cost and stay using univariate analysis. Multivariable survey logistic regression analysis was performed to evaluate predictors of utilization for ERCP among acute pancreatitis hospitalization. Results Among 2,632,309 hospitalizations for acute pancreatitis, 49108 (1.87%) had ERCP. The prevalence trend of ERCP declined from 3.88% in 2003 to 0.97% in 2014.(pTrend<0.0001). Patients with ERCP were older (>55-years old) (53.01% vs 39.36%;p<0.0001), female (58.45% vs 48.04%; p<0.0001), Hispanic (16.30% vs 12.86%; p<0.0001), utilizing Medicare (40.29% vs 31.88%; p<0.0001), elective admission (8.15% vs 4.98%; p<0.0001), and with gallbladder etiology (65.98% vs 26.06%; p<0.0001). Acute pancreatitis hospitalization with ERCP had a higher cost of utilization (Costdiff:+$25077;p<0.0001) and mean stay (LOSdiff:+3.5 days; p<0.0001). In regression analysis, old adults [Odds ratio(OR):1.087; Confidence interval (CI):1.008-1.173), Hispanic (OR:1.086; CI:1.019-1.156), asian (OR:1.146; CI:1.007-1.304), female (OR:1.074; CI:1.028-1.122), elective admission (OR:1.649; CI:1.524-1.785), gallbladder etiology (OR:4.437; CI:4.224-4.662), concurrent chronic pancreatitis (OR:1.643; CI:1.536-1.757), systemic inflammatory response syndrome (SIRS) (OR:1.264; CI:1.112-1.436), pleural effusion (OR:1.874; CI:1.231-2.854), and portal vein thrombosis (OR:1.646; CI:1.221-2.219). Conclusion In nationwide data, we have found a decreased utilization trend and higher hospital utilization cost and stay associated with ERCP. The predictors of utilization will be helpful to examine the cost-utility of ERCP, especially with the advent of acute pancreatitis treatment systems to mitigate the health care burden.
