The role of treatment of hepatitis C with direct-acting antiviral agents on glycaemic control in diabetic patients: An updated systematic review and meta-analysis.

Recent studies suggested that successful clearance of chronic Hepatitis C Virus (HCV) by using direct-acting antiviral (DAA) agents could improve glycemic control in patients with diabetes; however, some studies failed to identify this benefit. We conducted a systematic review and meta-analysis to assess the impact of sustained virologic response (SVR) after treatment with DAA agents on glycemic control. Embase, Scopus and PubMed were searched through March 26th, 2023, for all studies evaluating whether eradication of HCV infection with DAAs is associated with an impact on glycemic control. Only studies with data on glycemic control, including haemoglobin A1c (HbA1c), fasting glucose, or Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), at least 12-week post-SVR were included. Sixteen studies met our eligibility criteria and were included in qualitative analysis. The mean HbA1c was 8.05% (95% CI: 7.79%-8.31%) before treatment and 7.19% (95% CI: 6.98%-7.39%) after treatment. There was a significant mean absolute reduction in HbA1c of 0.72% (95% CI: 0.52%-0.93%) with high heterogeneity between studies (I2 = 91.7%). The reduction in HbA1c remained significant in the subgroup analysis at 3 months follow up post SVR [0.74% (95% CI: 0.57%-0.91%)] and at least 6 months follow up [0.66% (95% CI: 0.23%-1.10%)]. We found a significant reduction in HbA1C after SVR in patients with type 2 diabetes mellitus, reflecting better glycemic control with HCV eradication. This data highlights an important extrahepatic benefit of HCV eradication.

Safety and efficacy of EsoFLIP dilation in patients with esophageal dysmotility: a systematic review.

Esophageal manometry is utilized for the evaluation and classification of esophageal motility disorders. EndoFlip has been introduced as an adjunctive test to evaluate esophagogastric junction (EGJ) distensibility. Treatment options for achalasia and EGJ outflow obstruction (EGJOO) include pneumatic dilation, myotomy, and botulinum toxin. Recently, a therapeutic 30 mm hydrostatic balloon dilator (EsoFLIP, Medtronic, Minneapolis, MN, USA) has been introduced, which uses impedance planimetry technology like EndoFlip. We performed a systematic review to evaluate the safety and efficacy of EsoFLIP in the management of esophageal motility disorders. A systematic literature search was performed with Medline, Embase, Web of science, and Cochrane library databases from inception to November 2022 to identify studies utilizing EsoFLIP for management of esophageal motility disorders. Our primary outcome was clinical success, and secondary outcomes were adverse events. Eight observational studies including 222 patients met inclusion criteria. Diagnoses included achalasia (158), EGJOO (48), post-reflux surgery dysphagia (8), and achalasia-like disorder (8). All studies used 30 mm maximum balloon dilation except one which used 25 mm. The clinical success rate was 68.7%. Follow-up duration ranged from 1 week to a mean of 5.7 months. Perforation or tear occurred in four patients. EsoFLIP is a new therapeutic option for the management of achalasia and EGJOO and appears to be effective and safe. Future comparative studies with other therapeutic modalities are needed to understand its role in the management of esophageal motility disorders.

An End-to-End Artificial Intelligence of Things (AIoT) Solution for Protecting Pipeline Easements against External Interference-An Australian Use-Case.

High-pressure pipelines are critical for transporting hazardous materials over long distances, but they face threats from third-party interference activities. Preventive measures are implemented, but interference accidents can still occur, making the need for high-quality detection strategies vital. This paper proposes an end-to-end Artificial Intelligence of Things (AIoT) solution to detect potential interference threats in real time. The solution involves developing a smart visual sensor capable of processing images using state-of-the-art computer vision algorithms and transmitting alerts to pipeline operators in real time. The system's core is based on the object-detection model (e.g., You Only Look Once version 4 (YOLOv4) and DETR with Improved deNoising anchOr boxes (DINO)), trained on a custom Pipeline Visual Threat Assessment (Pipe-VisTA) dataset. Among the trained models, DINO was able to achieve the best Mean Average Precision (mAP) of 71.2% for the unseen test dataset. However, for the deployment on a limited computational-ability edge computer (i.e., the NVIDIA Jetson Nano), the simpler and TensorRT-optimized YOLOv4 model was used, which achieved a mAP of 61.8% for the test dataset. The developed AIoT device captures the image using a camera, processes on the edge using the trained YOLOv4 model to detect the potential threat, transmits the threat alert to a Fleet Portal via LoRaWAN, and hosts the alert on a dashboard via a satellite network. The device has been fully tested in the field to ensure its functionality prior to deployment for the SEA Gas use-case. The AIoT smart solution has been deployed across the 10km stretch of the SEA Gas pipeline across the Murray Bridge section. In total, 48 AIoT devices and three Fleet Portals are installed to ensure the line-of-sight communication between the devices and portals.

Efficacy of cap-assisted endoscopy for the visualization of the major duodenal papilla: a systematic review and meta-analysis.

BACKGROUND AND AIMS: The current standard of practice is to use a duodenoscope for the evaluation of the major duodenal papilla (MDP). Recently, cap-assisted endoscopy (CAE), which uses a transparent cap at the tip of a standard front-viewing endoscope, has emerged as an alternative. METHODS: A systematic literature search was performed in several databases from inception to January 2023 to identify studies evaluating the efficacy of CAE for the evaluation of the MDP. RESULTS: Nine studies including 806 patients met our inclusion criteria. The pooled rate of technical success for CAE was 93.2% (95% confidence interval, 85.6-96.9; I2 = 84.6%). A subgroup analysis comparing CAE with a standard endoscope showed higher odds for the evaluation of the MDP with CAE (but not a duodenoscope, which was better than CAE) with an odds ratio of 57.294 (95% confidence interval, 17.767-184.755; I2 = 45.303%). CONCLUSIONS: CAE offers a significant advantage with high rates of complete MDP evaluation compared with standard forward-viewing endoscopy. However, CAE is associated with lower rates of success when compared with side-viewing endoscopes.

Role of rifaximin in the management of alcohol-associated hepatitis: A systematic review and meta-analysis.

BACKGROUND AND AIM: Alcohol-associated hepatitis (AAH) is an acute, inflammatory liver disease with severe short-term and long-term morbidity and mortality. AAH can lead to severe complications including hepatic failure, gastrointestinal bleeding, sepsis, and the development or decompensation of cirrhosis. Rifaximin is an antibiotic that reduces bacterial overgrowth and gut translocation, and it may have a role in decreasing systemic inflammation and infection in patients with AAH. Therefore, we conducted a systematic review and meta-analysis to evaluate the role of rifaximin in the management of AAH. METHODS: A comprehensive search strategy was used to identify studies that met our inclusion criteria in Embase, MEDLINE (PubMed), Cochrane Library, Web of Science Core Collection, and Google Scholar. Outcomes of interest included rates of infection, 90-day mortality, and overall mortality between the rifaximin versus non-rifaximin group. Open Meta Analyst software was used to compute the results. RESULTS: Three studies with a total of 162 patients were included in the final meta-analysis. Of the three studies, two were randomized control trials (RCTs), and one was a case-control study. There was a significantly lower rate of infection in the rifaximin group versus the non-rifaximin group (RR: 0.331, 95% CI: 0.159-0.689, I2  = 0%, P = 0.003). There was no significant difference in 90-day mortality in the rifaximin versus non-rifaximin group (RR: 0.743, 95% CI: 0.298-1.850, I2  = 24%, P = 0.523), nor was there a significant difference in overall mortality (RR: 0.624, 95% 95% CI: 0.299-1.3, I2  = 7.1%, P = 0.208). CONCLUSIONS: The use of rifaximin in AAH is associated with a lower rate of infection rate than the non-rifaximin group. Additional research is needed to determine whether this effect is more pronounced in patients concurrently being treated with prednisolone. Differences in 90-day or overall mortality did not reach statistical significance. Further studies, particularly large randomized controlled trials, are needed to establish the role of rifaximin in AAH, especially as an adjunct therapy with prednisolone.

Safety and Efficacy of Endoscopic Retrograde Cholangiopancreatography in Nonagenarians: A Systematic Review and Meta-Analysis.

BACKGROUND: Recent advances in modern medicine have translated into increase in life expectancy in the USA and with that, a rise in the demand for invasive procedures in elderly patients. Endoscopic retrograde cholangiopancreatography (ERCP) is the procedure of choice for managing various benign and malignant pancreatobiliary conditions and can be associated with various adverse events. AIM: We performed a systematic review and meta-analysis to evaluate outcomes of ERCP in nonagenarians. METHODS: A comprehensive literature search was performed in Embase, MEDLINE, Web of Science, and Cochrane Review library until July 2020. Our primary outcomes were the rate of technical success and adverse events in nonagenarians. Secondary outcomes were comparison of technical success and adverse events compared with younger patients. RESULTS: The initial search revealed 4933 studies, of which 24 studies with 5521 patients met our inclusion criteria. Pooled technical success rate of ERCP in nonagenarians was 92%, and pooled adverse event rate was 7.8%. There was no significant difference in technical success rate and overall rate of adverse events comparing ERCP outcomes in nonagenarians with a relatively younger population. The risk of post-ERCP bleeding was significantly higher in nonagenarians compared to younger patients with OR = 1.986 [1.113-3.544], I2 = 0. ERCP-related mortality was also significantly higher in nonagenarians compared to younger patients with OR = 4.720 [1.368-16.289], I2 = 0. CONCLUSION: There was no significant difference in technical success rate and risk of adverse events related to ERCP in nonagenarians compared to younger patients. However, the risk of bleeding and procedure-related mortality was significantly higher.

V2ReID: Vision-Outlooker-Based Vehicle Re-Identification.

With the increase of large camera networks around us, it is becoming more difficult to manually identify vehicles. Computer vision enables us to automate this task. More specifically, vehicle re-identification (ReID) aims to identify cars in a camera network with non-overlapping views. Images captured of vehicles can undergo intense variations of appearance due to illumination, pose, or viewpoint. Furthermore, due to small inter-class similarities and large intra-class differences, feature learning is often enhanced with non-visual cues, such as the topology of camera networks and temporal information. These are, however, not always available or can be resource intensive for the model. Following the success of Transformer baselines in ReID, we propose for the first time an outlook-attention-based vehicle ReID framework using the Vision Outlooker as its backbone, which is able to encode finer-level features. We show that, without embedding any additional side information and using only the visual cues, we can achieve an 80.31% mAP and 97.13% R-1 on the VeRi-776 dataset. Besides documenting our research, this paper also aims to provide a comprehensive walkthrough of vehicle ReID. We aim to provide a starting point for individuals and organisations, as it is difficult to navigate through the myriad of complex research in this field.

Edge-Computing Video Analytics Solution for Automated Plastic-Bag Contamination Detection: A Case from Remondis.

The increased global waste generation rates over the last few decades have made the waste management task a significant problem. One of the potential approaches adopted globally is to recycle a significant portion of generated waste. However, the contamination of recyclable waste has been a major problem in this context and causes almost 75% of recyclable waste to be unusable. For sustainable development, efficient management and recycling of waste are of huge importance. To reduce the waste contamination rates, conventionally, a manual bin-tagging approach is adopted; however, this is inefficient and requires huge labor effort. Within household waste contamination, plastic bags have been found to be one of the main contaminants. Towards automating the process of plastic-bag contamination detection, this paper proposes an edge-computing video analytics solution using the latest Artificial Intelligence (AI), Artificial Intelligence of Things (AIoT) and computer vision technologies. The proposed system is based on the idea of capturing video of waste from the truck hopper, processing it using edge-computing hardware to detect plastic-bag contamination and storing the contamination-related information for further analysis. Faster R-CNN and You Only Look Once version 4 (YOLOv4) deep learning model variants are trained using the Remondis Contamination Dataset (RCD) developed from Remondis manual tagging historical records. The overall system was evaluated in terms of software and hardware performance using standard evaluation measures (i.e., training performance, testing performance, Frames Per Second (FPS), system usage, power consumption). From the detailed analysis, YOLOv4 with CSPDarkNet_tiny was identified as a suitable candidate with a Mean Average Precision (mAP) of 63% and FPS of 24.8 with NVIDIA Jetson TX2 hardware. The data collected from the deployment of edge-computing hardware on waste collection trucks was used to retrain the models and improved performance in terms of mAP, False Positives (FPs), False Negatives (FNs) and True Positives (TPs) was achieved for the retrained YOLOv4 with CSPDarkNet_tiny backbone model. A detailed cost analysis of the proposed system is also provided for stakeholders and policy makers.

Role of routine second-look endoscopy in patients with acute peptic ulcer bleeding: meta-analysis of randomized controlled trials.

BACKGROUND AND AIMS: Studies evaluating the role of routine second-look endoscopy in patients with acute upper GI bleed because of peptic ulcer disease (PUD) have reported conflicting results. This meta-analysis evaluates the usefulness of routine second-look endoscopy in these patients. METHODS: We reviewed several databases from inception to September 15, 2020 to identify randomized controlled trials (RCTs) that compared routine second-look endoscopy with no planned second-look endoscopy in patients with acute upper GI bleed because of PUD. Our outcomes of interest were recurrent bleeding, mortality, need for surgery, and mean number of units of blood transfused. For categorical variables, we calculated pooled risk ratios (RRs) with 95% confidence intervals (CIs); for continuous variables, we calculated standardized mean difference with 95% CIs. Data were analyzed using a random effects model. We used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework to ascertain the quality of evidence. RESULTS: We included 9 RTCs comprising 1452 patients; 726 patients underwent planned/routine second-look endoscopy and 726 did not. We found no significant difference in recurrent bleeding (RR, .79; 95% CI, .51-1.23), need for surgery (RR, .58; 95% CI, .29-1.15), mortality (RR, .69; 95% CI, .33-1.45), or mean number of units of blood transfused (standardized mean difference, -.06; 95% CI, -.19 to .07). Quality of evidence ranged from low to moderate based on the GRADE framework. CONCLUSIONS: Single endoscopy with complete endoscopic hemostasis is not inferior to routine second-look endoscopy in reducing the risk of recurrent bleeding, mortality, or need for surgery in patients with acute upper GI bleed because of PUD.

Colorectal Cancer Screening Guidelines Are Primarily Based on Low-Moderate-Quality Evidence.

BACKGROUND: Owning to colorectal cancer's (CRC) high mortality, multiple societies developed screening guidelines. AIMS: We aimed to assess the overall quality of CRC screening guidelines. METHODS: A systematic search was performed to review CRC screening guidelines for conflicts of interest (COI), recommendation quality and strength, external document review, use of patient representative, and recommendation age-as per Institute of Medicine (IOM) standards. In addition, recommendations were compared between guidelines/societies. Statistical analysis was conducted using R. RESULTS: Twelve manuscripts were included in final analysis. Not all guidelines reported on COI, provided a grading method, underwent external review, or included patient representation. 14.5%, 34.2%, and 51.3% of recommendations were based on high-, moderate-, and low-quality evidence, respectively. 27.8%, 54.6%, and 17.5% of recommendations were strong, weak/conditional, and did not provide a strength, respectively. The proportion of high-quality evidence and strong recommendations did not significantly differ across societies, nor were significant associations between publication year and evidence quality seen (P = 0.4). CONCLUSIONS: While the majority of the CRC guidelines contain aspects of the standards set forth by the IOM, there is an overall lack of adherence. As over 85% of recommendations are based on low-moderate quality evidence, further studies on CRC screening are warranted to improve the overall quality of evidence.

Peroral Endoscopic Myotomy Is a Safe and Feasible Option in Management of Esophageal Diverticula: Systematic Review and Meta-Analysis.

Esophageal diverticula can cause significant symptoms and affect the quality of life. There has been recent interest in the use of peroral endoscopic myotomy in the management of esophageal diverticula (D-POEM). In this meta-analysis, we have evaluated the efficacy and safety of D-POEM in the management of esophageal diverticula. Several databases were reviewed from inception to 6/19/2020 to identify the studies evaluating the feasibility, efficacy and safety of D-POEM in the management of esophageal diverticula. Our outcomes of interest were technical success, adverse events and difference in mean pre- and post-procedure symptom score. We performed subgroup analysis including patients with Zenker's diverticulum who underwent POEM (Z-POEM). Pooled rates with 95% confidence intervals (CI) for all outcomes were calculated using random effect model. We calculated standard mean difference (SMD) with 95% CI to compare mean pre- and post-procedure symptom score. We included 7 studies with 233 patients. For D-POEM, pooled rates (95% CI) for technical success and adverse events were 95% (91%, 97%) and 6% (3%, 10%) respectively. For Z-POEM, pooled rates (95% CI) for technical success and adverse events were 95% (90%, 97%) and 6% (3%, 10%) respectively. Mean post-procedure symptom score for all patients who underwent D-POEM was significantly lower compared to mean pre-procedure symptom score, SMD (95% CI) 2.17 (1.51, 2.83).  This meta-analysis demonstrated that D-POEM is a safe and feasible option for patients with symptomatic esophageal diverticula.

Trends in Mortality From Extrahepatic Complications in Patients With Chronic Liver Disease, From 2007 Through 2017.

BACKGROUND & AIMS: Trends of mortality associated with extrahepatic complications of chronic liver disease might be changing. We studied trends in mortality from extrahepatic complications of viral hepatitis, alcoholic liver disease (ALD), and nonalcoholic fatty liver disease in the United States. METHODS: We performed a population-based study using US Census and the National Center for Health Statistics mortality records from 2007 through 2017. We identified trends in age-standardized mortality using Joinpoint trend analysis with estimates of annual percent change. RESULTS: The liver-related mortality among patients with hepatitis C virus (HCV) infection increased from 2007 through 2013 and then decreased once patients began receiving treatment with direct-acting antiviral (DAA) agents, from 2014 through 2017. Among patients with HCV infection, the age-standardized mortality for extrahepatic cancers was 2.6%, for cardiovascular disease was 1.9%, and for diabetes was 3.3%. Among individuals with hepatitis B virus infection, liver-related mortality decreased steadily from 2007 through 2017. During the study, age-standardized mortality from hepatitis B virus-related extrahepatic complications increased by an average of 2.0% each year. Although liver-related mortality from ALD continued to increase, mortality from extrahepatic complications of ALD did not change significantly during the 11-year study. Among patients with nonalcoholic fatty liver disease, the cause of death was most frequently cardiovascular disease, which increased gradually over the study period, whereas liver-related mortality increased rapidly. CONCLUSIONS: In an analysis of US Census and the National Center for Health Statistics mortality records, we found that after widespread use of DAA agents for treatment of viral hepatitis, cause-specific mortality from extrahepatic cancers increased, whereas mortality from cardiovascular disease or diabetes increased only among patients with HCV infection. These findings indicate the need to reassess risk and risk factors for extrahepatic cancer, cardiovascular disease, and diabetes in individuals successfully treated for HCV infection with DAA agents.

No Association Linking Short-Term Proton Pump Inhibitor Use to Dementia: Systematic Review and Meta-analysis of Observational Studies.

INTRODUCTION: Long-term use of proton pump inhibitors (PPIs) has been associated with a wide variety of potentially serious adverse effects including a possible increased risk of dementia. Studies evaluating this association have reached divergent conclusions. We aimed to evaluate this proposed association further and to assess the quality of the evidence in its support. METHODS: We searched MEDLINE, EMBASE, ISI Web of Science, and Cochrane databases for studies examining a link between PPI use and dementia, up to February 2019. Studies reporting summary results as hazard ratio (HR) or odds ratio (OR) were pooled using the DerSimonian and Laird random-effects model for meta-analyses. Methodological quality of individual observational studies was assessed using the Newcastle-Ottawa scale and the overall quality of evidence rated as per the GRADE approach. RESULTS: We identified and included 11 observational studies comprising 642,949 subjects; 64% were women. Most studies were short-term ranging from 5 to 10 years. There were 158,954 PPI users and 483,995 nonusers. For studies summarizing data as adjusted HR, pooled HR for all causes of dementia was 1.10 (0.88-1.37); for Alzheimer dementia only, it was 1.06 (0.72-1.55). For studies summarizing data as adjusted OR, pooled OR for all causes of dementia was 1.03 (0.84-1.25) and for Alzheimer dementia only 0.96 (0.82-1.11). Per Newcastle-Ottawa scale assessment, 10 studies were of high quality and 1 was of moderate quality. By applying GRADE methodology, quality of evidence for both outcomes was very low. DISCUSSION: We found no evidence to support the proposed association between PPI use and an increased risk of dementia. PPI use among patients who have a valid indication for it, should not be curtailed because of concerns about dementia risk.

Emergent versus urgent ERCP in acute cholangitis: a systematic review and meta-analysis.

BACKGROUND AND AIMS: Acute cholangitis is characterized by abdominal pain, fever, and jaundice. Most patients respond to medical management with intravenous hydration and antibiotics. About 20% to 30% require biliary drainage, and ERCP is the procedure of choice. We conducted a systematic review and meta-analysis to evaluate the impact of emergent biliary drainage on patient outcomes. METHODS: A comprehensive literature review was conducted by searching the Embase and PubMed databases from inception to April 2019 to identify all studies that evaluated the impact of timing of ERCP on patient outcomes. Our primary outcome was in-hospital mortality (IHM), and secondary outcomes were length of stay (LOS), organ failure, and 30-day mortality. Fixed and random effects models were used to generate pooled measures of IHM, 30-day mortality, and LOS. RESULTS: Nine observational studies involving 7534 patients were included in the primary meta-analysis. IHM was significantly lower in patients who underwent emergent biliary drainage within 48 hours (odds ratio [OR], 0.52; 95% confidence interval [CI], 0.28-0.98). As a sensitivity analysis, we pooled the data from 2 population registry studies of 81,893 patients, which yielded consistent results for the main outcomes. LOS was also significantly lower in patients who underwent ERCP within 48 hours with a mean difference of 5.56 days (95% CI, 1.59-9.53). Patients who underwent emergent ERCP also had lower odds of 30-day mortality (OR, 0.39; 95% CI, 0.14-1.08) and organ failure (OR, 0.69; 95% CI, 0.33-1.46). CONCLUSIONS: Our study reveals that performing emergent ERCP within 48 hours in patients with acute cholangitis is associated with lower IHM, 30-day mortality, organ failure, and shorter LOS.

Efficacy and safety of tranexamic acid in acute upper gastrointestinal bleeding: meta-analysis of randomised controlled trials.

BACKGROUND: Studies evaluating the role of tranexamic acid in acute upper GI bleeding (UGIB) have reported conflicting results. In this systematic review, we have evaluated the efficacy and safety of tranexamic acid in UGIB. METHODS: We searched several databases from inception to June 6, 2020 to identify randomised controlled trials (RCTs) that compared tranexamic acid and placebo in UGIB. Our outcomes of interest were mortality, rebleeding, all thromboembolic events, venous thromboembolic events, need for transfusion, endoscopic intervention and surgery. Pooled risk ratios (RR) with 95% confidence intervals (CI) were calculated using fixed effect model. We used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework to assess the certainty of evidence. RESULTS: We included 12 RCTs comprising 14,100 patients. We found no significant difference in mortality, pooled RR (95% CI) 0.87 (0.74-1.01), rebleeding, pooled RR (95% CI) 0.90 (0.79-1.02), need for surgery, pooled RR (95% CI) 0.86 (0.73-1.02), need for transfusion, pooled RR (95% CI) 1.00 (0.99-1.01) or thromboembolic events, RR (95% CI) 1.16 (0.87-1.56) between treatments. We found an increased risk of venous thromboembolic events with tranexamic acid, pooled RR (95% CI) 1.94 (1.23-3.05). Certainty of evidence based on the GRADE framework for the different outcomes ranged from low to very low. CONCLUSIONS: Tranexamic acid does not improve outcomes in UGIB and may increase the risk of venous thromboembolic events.

Readmission Rates and Associated Outcomes for Alcoholic Hepatitis: A Nationwide Cohort Study.

BACKGROUND/AIMS: Alcoholic hepatitis (AH) can lead to sudden and severe hepatic decompensation necessitating recurrent hospitalizations. We evaluated the trends, predictors, and healthcare cost burden of AH-related readmissions in the USA. METHODS: Utilizing the National Readmissions Database 2010-2014, we performed a retrospective longitudinal analysis to identify the index readmission with AH for up to 90 days after discharge. Annual trends of 30- and 90-day AH-related readmissions were calculated. Predictors of 30- and 90-day readmission were determined by multivariate logistic regression. Annual healthcare cost burden associated with AH-linked readmissions was estimated. RESULTS: Of the 21,572 (unweighted: 50,769) AH-related hospitalizations, 4917 (22.8%) and 7890 (36.6%) were readmitted in 30 and 90 day, respectively, with rates that were statistically unchanged from 2010 to 2014. Predictors of 30-day readmissions included female gender, hepatitis C virus infection, cirrhosis, ascites, acute kidney injury, urinary tract infection, history of bariatric surgery, chronic pancreatitis, and high medical comorbidity index. Acute pancreatitis and palliative care consultation were associated with a lower risk of 30-day readmission. Predictors of 90-day readmission were similar to risk factors for 30-day readmission. From 2010 to 2014, the annual cost (and total hospitalization days) burden increased in 2014 to $164 million (22,244 days) and $321 million (42,772 days) for 30- and 90-day AH-related readmissions, respectively. CONCLUSION: Despite relatively stable trends in AH-related readmission, the total LOS and cost has been rising. A target-directed approach with a focus on high-risk subpopulations may help understand the unique challenges associated with the rising cost of AH-related readmissions.
