Item A Comparative Analysis of Bleeding Peptic Ulcers in Hospitalizations With and Without End-Stage Renal Disease(Elmer Press, 2023) Dahiya, Dushyant Singh; Mandoorah, Sohaib; Gangwani, Manesh Kumar; Ali, Hassam; Merza, Nooraldin; Aziz, Muhammad; Singh, Amandeep; Perisetti, Abhilash; Garg, Rajat; Cheng, Chin-I; Dutta, Priyata; Inamdar, Sumant; Sanaka, Madhusudhan R.; Al-Haddad, Mohammad; Medicine, School of MedicineBackground: End-stage renal disease (ESRD) patients are highly susceptible to peptic ulcer bleeding (PUB). We aimed to assess the influence of ESRD status on PUB hospitalizations in the United States (USA). Methods: We analyzed the National Inpatient Sample to identify all adult PUB hospitalizations in the USA from 2007 to 2014, which were divided into two subgroups based on the presence or absence of ESRD. Hospitalization characteristics and clinical outcomes were compared. Furthermore, predictors of inpatient mortality for PUB hospitalizations with ESRD were identified. Results: Between 2007 and 2014, there were 351,965 PUB hospitalizations with ESRD compared to 2,037,037 non-ESRD PUB hospitalizations. PUB ESRD hospitalizations had a higher mean age (71.6 vs. 63.6 years, P < 0.001), and proportion of ethnic minorities i.e., Blacks, Hispanics, and Asians compared to the non-ESRD cohort. We also noted higher all-cause inpatient mortality (5.4% vs. 2.6%, P < 0.001), rates of esophagogastroduodenoscopy (EGD) (20.7% vs. 19.1%, P < 0.001), and mean length of stay (LOS) (8.2 vs. 6 days, P < 0.001) for PUB ESRD hospitalizations compared to the non-ESRD cohort. After multivariate logistic regression analysis, Whites with ESRD had higher odds of mortality from PUB compared to Blacks. Furthermore, the odds of inpatient mortality from PUB decreased by 0.6% for every 1-year increase in age for hospitalizations with ESRD. Compared to the 2011 - 2014 study period, the 2007 - 2010 period had 43.7% higher odds (odds ratio (OR): 0.696, 95% confidence interval (CI): 0.645 - 0.751) of inpatient mortality for PUB hospitalizations with ESRD. Conclusions: PUB hospitalizations with ESRD had higher inpatient mortality, EGD utilization, and mean LOS compared to non-ESRD PUB hospitalizations.Item Acute pancreatitis in liver transplant hospitalizations: Identifying national trends, clinical outcomes and healthcare burden in the United States(Baishideng Publishing Group, 2023) Dahiya, Dushyant Singh; Jahagirdar, Vinay; Chandan, Saurabh; Gangwani, Manesh Kumar; Merza, Nooraldin; Ali, Hassam; Deliwala, Smit; Aziz, Muhammad; Ramai, Daryl; Pinnam, Bhanu Siva Mohan; Bapaye, Jay; Cheng, Chin-I; Inamdar, Sumant; Sharma, Neil R.; Al-Haddad, Mohammad; Medicine, School of MedicineBackground: Acute pancreatitis (AP) in liver transplant (LT) recipients may lead to poor clinical outcomes and development of severe complications. Aim: We aimed to assess national trends, clinical outcomes, and the healthcare burden of LT hospitalizations with AP in the United States (US). Methods: The National Inpatient Sample was utilized to identify all adult (≥ 18 years old) LT hospitalizations with AP in the US from 2007-2019. Non-LT AP hospitalizations served as controls for comparative analysis. National trends of hospitalization characteristics, clinical outcomes, complications, and healthcare burden for LT hospitalizations with AP were highlighted. Hospitalization characteristics, clinical outcomes, complications, and healthcare burden were also compared between the LT and non-LT cohorts. Furthermore, predictors of inpatient mortality for LT hospitalizations with AP were identified. All P values ≤ 0.05 were considered statistically significant. Results: The total number of LT hospitalizations with AP increased from 305 in 2007 to 610 in 2019. There was a rising trend of Hispanic (16.5% in 2007 to 21.1% in 2018, P-trend = 0.0009) and Asian (4.3% in 2007 to 7.4% in 2019, p-trend = 0.0002) LT hospitalizations with AP, while a decline was noted for Blacks (11% in 2007 to 8.3% in 2019, P-trend = 0.0004). Furthermore, LT hospitalizations with AP had an increasing comorbidity burden as the Charlson Comorbidity Index (CCI) score ≥ 3 increased from 41.64% in 2007 to 62.30% in 2019 (P-trend < 0.0001). We did not find statistically significant trends in inpatient mortality, mean length of stay (LOS), and mean total healthcare charge (THC) for LT hospitalizations with AP despite rising trends of complications such as sepsis, acute kidney failure (AKF), acute respiratory failure (ARF), abdominal abscesses, portal vein thrombosis (PVT), and venous thromboembolism (VTE). Between 2007-2019, 6863 LT hospitalizations with AP were compared to 5649980 non-LT AP hospitalizations. LT hospitalizations with AP were slightly older (53.5 vs 52.6 years, P = 0.017) and had a higher proportion of patients with CCI ≥ 3 (51.5% vs 19.8%, P < 0.0001) compared to the non-LT cohort. Additionally, LT hospitalizations with AP had a higher proportion of Whites (67.9% vs 64.6%, P < 0.0001) and Asians (4% vs 2.3%, P < 0.0001), while the non-LT cohort had a higher proportion of Blacks and Hispanics. Interestingly, LT hospitalizations with AP had lower inpatient mortality (1.37% vs 2.16%, P = 0.0479) compared to the non-LT cohort despite having a higher mean age, CCI scores, and complications such as AKF, PVT, VTE, and the need for blood transfusion. However, LT hospitalizations with AP had a higher mean THC ($59596 vs $50466, P = 0.0429) than the non-LT cohort. Conclusion: In the US, LT hospitalizations with AP were on the rise, particularly for Hispanics and Asians. However, LT hospitalizations with AP had lower inpatient mortality compared to non-LT AP hospitalizations.Item Basic Principles and Role of Endoscopic Ultrasound in Diagnosis and Differentiation of Pancreatic Cancer from Other Pancreatic Lesions: A Comprehensive Review of Endoscopic Ultrasound for Pancreatic Cancer(MDPI, 2024-04-28) Dahiya, Dushyant Singh; Shah, Yash R.; Ali, Hassam; Chandan, Saurabh; Gangwani, Manesh Kumar; Canakis, Andrew; Ramai, Daryl; Hayat, Umar; Pinnam, Bhanu Siva Mohan; Iqbal, Amna; Malik, Sheza; Singh, Sahib; Jaber, Fouad; Alsakarneh, Saqr; Mohamed, Islam; Ali, Meer Akbar; Al-Haddad, Mohammad; Inamdar, Sumant; Medicine, School of MedicinePancreatic cancer is one of the leading causes of cancer-related deaths worldwide. Pancreatic lesions consist of both neoplastic and non-neoplastic lesions and often pose a diagnostic and therapeutic challenge due to similar clinical and radiological features. In recent years, pancreatic lesions have been discovered more frequently as incidental findings due to the increased utilization and widespread availability of abdominal cross-sectional imaging. Therefore, it becomes imperative to establish an early and appropriate diagnosis with meticulous differentiation in an attempt to balance unnecessary treatment of benign pancreatic lesions and missing the opportunity for early intervention in malignant lesions. Endoscopic ultrasound (EUS) has become an important diagnostic modality for the identification and risk stratification of pancreatic lesions due to its ability to provide detailed imaging and acquisition of tissue samples for analysis with the help of fine-needle aspiration/biopsy. The recent development of EUS-based technology, including contrast-enhanced endoscopic ultrasound, real-time elastography–endoscopic ultrasound, miniature probe ultrasound, confocal laser endomicroscopy, and the application of artificial intelligence has significantly augmented the diagnostic accuracy of EUS as it enables better evaluation of the number, location, dimension, wall thickness, and contents of these lesions. This article provides a comprehensive overview of the role of the different types of EUS available for the diagnosis and differentiation of pancreatic cancer from other pancreatic lesions while discussing their key strengths and important limitations.Item Celiac disease hospitalizations: an emerging challenge in the United States(Hellenic Society of Gastroenterology, 2022) Dahiya, Dushyant Singh; Al-Haddad, Mohammad; Perisetti, Abhilash; Singh, Amandeep; Goyal, Hemant; Cheng, Chin-I; Garg, Rajat; Pisipati, Sailaja; Ameyi, Justice; Sanaka, Madhusudhan R.; Inamdar, Sumant; Medicine, School of MedicineBackground: This study aimed to assess the trends and characteristics of celiac disease (CeD) hospitalizations in the United States (US). Methods: The National Inpatient Sample was analyzed from 2007-2017 to identify all adult hospitalizations with a primary discharge diagnosis of CeD. Demographic trends, associations, and other aspects of CeD hospitalizations were analyzed. SAS 9.4 was used for statistical analysis and P-values ≤0.05 were considered statistically significant. Results: From 2007-2017, we noted an increasing trend of CeD hospitalizations from 19,385 in 2007 to 38,395 in 2017 (P-trend <0.001). The mean age was 57.85 years, with a declining trend. Females and patients with a Charlson Comorbidity Index score ≥3 had a rising trend of CeD hospitalizations from 70.68% in 2007 to 73% in 2017 (P-trend <0.001) and from 16.96% in 2007 to 26.59% in 2017 (P-trend <0.001), respectively. Additionally, a White predominance was seen in the study cohort. Furthermore, for CeD hospitalizations, all-cause inpatient mortality increased from 1.30% in 2007 to 1.58% in 2017 (P-trend <0.001) and the mean total hospital charge increased from $26,299 in 2007 to $49,282 in 2017 (P-trend <0.001). However, we noted a decline in the mean length of stay (LOS) from 4.88 days in 2007 to 4.59 days in 2017 (P-trend=0.0015) and rates of esophagogastroduodenoscopy performed from 2.09% in 2007 to 1.89% in 2017 (P-trend <0.001). Conclusion: We noted a rising trend in hospitalizations, inpatient mortality, and hospital costs for CeD hospitalizations in the US; however, inpatient EGDs performed and mean LOS showed a decline.Item Clinical Outcomes and Complications for Achalasia Patients Admitted After Per-Oral Endoscopic Myotomy(Elmer Press, 2023) Dahiya, Dushyant Singh; Nivedita, Fnu; Perisetti, Abhilash; Goyal, Hemant; Inamdar, Sumant; Gangwani, Manesh Kumar; Aziz, Muhammad; Ali, Hassam; Cheng, Chin-I; Sanaka, Madhusudhan R.; Al-Haddad, Mohammad; Sharma, Neil R.; Medicine, School of MedicineBackground: Per-oral endoscopic myotomy (POEM) is a rapidly emerging minimally invasive procedure for management of achalasia. Same-day discharge after POEM is safe and feasible; however, some patients may need hospitalization. We aimed to identify characteristics and outcomes for achalasia patients requiring hospitalizations after POEM in the United States (US). Methods: The US National Inpatient Sample was utilized to identify all adult achalasia patients who were admitted after POEM from 2016 to 2019. Hospitalization characteristics and clinical outcomes were highlighted. Results: From 2016 to 2019, we found that 1,885 achalasia patients were admitted after POEM. There was an increase in the total number of hospitalizations after POEM from 380 in 2016 to 490 in 2019. The mean age increased from 54.2 years in 2016 to 59.3 years in 2019. Most POEM-related hospitalizations were for the 65 - 79 age group (31.8%), females (50.4%), and Whites (68.4%). A majority (56.2%) of the study population had a Charlson Comorbidity Index of 0. The Northeast hospital region had the highest number of POEM-related hospitalizations. Most of these patients (88.3%) were eventually discharged home. There was no inpatient mortality. The mean length of stay decreased from 4 days in 2016 to 3.2 days in 2019, while the mean total healthcare charge increased from $52,057 in 2016 to $65,109 in 2019. Esophageal perforation was the most common complication seen in 1.3% of patients. Conclusion: The number of achalasia patients needing hospitalization after POEM increased. There was no inpatient mortality conferring an excellent safety profile of this procedure.Item Early and Late Readmissions of Radiation Proctitis in the United States: Are We Getting Better?(MDPI, 2024-01-12) Dahiya, Dushyant Singh; Pinnam, Bhanu Siva Mohan; Ishaya, Michelle; Chandan, Saurabh; Gangwani, Manesh Kumar; Singh, Sahib; Ali, Hassam; Sohail, Amir Humza; Canakis, Andrew; Ramai, Daryl; Zelt, Christina; Inamdar, Sumant; Al-Haddad, Mohammad; Rojas-DeLeon, Mariajose; Sharma, Neil R.; Medicine, School of MedicineBackground/Aims: Radiation proctitis (RP), a well-known complication of pelvic radiation therapy, may lead to recurrent hospitalizations. We aimed to assess readmissions of RP in the United States. Methods: We analyzed the Nationwide Readmission Database from 2016 to 2020 to identify all 30-, 60-, and 90-day readmissions of RP in the United States. Hospitalization characteristics, predictors, clinical outcomes, and healthcare burdens were assessed. Results: From 2016 to 2020, we noted a declining trend of 30-, 60-, and 90-day readmissions of RP in the US. However, the all-cause 30-, 60-, and 90-day readmission rates of RP were still high at 13.7%, 19.4%, and 23.16%, respectively. On readmission, RP was identified as the admitting diagnosis in only 20.61%, 17.87%, and 15.76% of 30-, 60-, and 90-day readmissions, respectively. The mean age for all readmissions was 70 years with a significant male dominance. Lower endoscopy at index admission reduced the risk of readmissions within 90 days, but this was not statistically significant. However, the Charlson Comorbidity Index (CCI) score was an independent predictor of all readmissions. Furthermore, the mean length of stay was 5.57 (95% CI 5.15-6), 5.50 (95% CI 5.12-5.89), and 5.47 (95% CI 5.07-5.87) days and the mean hospitalization charge was USD 60,451 (95% CI USD 54,728-66,174), USD 62,671 (95% CI USD 57,326-68,015), and USD 62,144 (95% CI USD 57,144-67,144) for 30-, 60-, and 90-day readmissions. The all-cause inpatient mortality for 30-, 60-, and 90-day readmissions was 3.58%, 3.89%, and 3.46%, respectively. Conclusions: RP readmissions are a significant healthcare burden. Further efforts must be directed toward improving management strategies to reduce readmission rates.Item Endoscopic versus surgical management for colonic volvulus hospitalizations in the United States(Korean Society of Gastrointestinal Endoscopy, 2023) Dahiya, Dushyant Singh; Perisetti, Abhilash; Goyal, Hemant; Inamdar, Sumant; Singh, Amandeep; Garg, Rajat; Cheng, Chin-I; Al-Haddad, Mohammad; Sanaka, Madhusudhan R.; Sharma, Neil; Medicine, School of MedicineBackground/aims: Colonic volvulus (CV), a common cause of bowel obstruction, often requires intervention. We aimed to identify hospitalization trends and CV outcomes in the United States. Methods: We used the National Inpatient Sample to identify all adult CV hospitalizations in the United States from 2007 to 2017. Patient demographics, comorbidities, and inpatient outcomes were highlighted. Outcomes of endoscopic and surgical management were compared. Results: From 2007 to 2017, there were 220,666 CV hospitalizations. CV-related hospitalizations increased from 17,888 in 2007 to 21,715 in 2017 (p=0.001). However, inpatient mortality decreased from 7.6% in 2007 to 6.2% in 2017 (p<0.001). Of all CV-related hospitalizations, 13,745 underwent endoscopic intervention, and 77,157 underwent surgery. Although the endoscopic cohort had patients with a higher Charlson comorbidity index, we noted lower inpatient mortality (6.1% vs. 7.0%, p<0.001), mean length of stay (8.3 vs. 11.8 days, p<0.001), and mean total healthcare charge ($68,126 vs. $106,703, p<0.001) compared to the surgical cohort. Male sex, increased Charlson comorbidity index scores, acute kidney injury, and malnutrition were associated with higher odds of inpatient mortality in patients with CV who underwent endoscopic management. Conclusion: Endoscopic intervention has lower inpatient mortality and is an excellent alternative to surgery for appropriately selected CV hospitalizations.Item Increasing thirty-day readmissions of Crohn's disease and ulcerative colitis in the United States: A national dilemma(Baishideng Publishing Group, 2022) Dahiya, Dushyant Singh; Perisetti, Abhilash; Kichloo, Asim; Singh, Amandeep; Goyal, Hemant; Rotundo, Laura; Vennikandam, Madhu; Shaka, Hafeez; Singh, Gurdeep; Singh, Jagmeet; Pisipati, Sailaja; Al-Haddad, Mohammad; Sanaka, Madhusudhan R.; Inamdar, Sumant; Medicine, School of MedicineBackground: The prevalence of Crohn's disease (CD) and ulcerative colitis (UC) is on the rise worldwide. This rising prevalence is concerning as patients with CD and UC may frequently relapse leading to recurrent hospitalizations and increased healthcare utilization. Aim: To identify trends and adverse outcomes for 30 d readmissions for CD and UC. Methods: This was a retrospective, interrupted trends study involving all adult (≥ 18 years) 30 d readmissions of CD and UC from the National Readmission Database (NRD) between 2008 and 2018. Patients < 18 years, elective, and traumatic hospitalizations were excluded from this study. We identified hospitalization characteristics and readmission rates for each calendar year. Trends of inpatient mortality, mean length of hospital stay (LOS) and mean total hospital cost (THC) were calculated using a multivariate logistic trend analysis adjusting for age, gender, insurance status, comorbidity burden and hospital factors. Furthermore, trends between CD and UC readmissions were compared using regression of the interaction coefficient after adjusting for age and gender to determine relative trends between the two populations. Stata® Version 16 software (StataCorp, TX, United States) was used for statistical analysis and P value ≤ 0.05 were considered statistically significant. Results: Total number of 30 d readmissions increased from 6202 in 2010 to 7672 in 2018 for CD and from 3272 in 2010 to 4234 in 2018 for UC. We noted increasing trends for 30-day all-cause readmission rate of CD from 14.9% in 2010 to 17.6% in 2018 (P-trend < 0.001), CD specific readmission rate from 7.1% in 2010 to 8.2% in 2018 (P-trend < 0.001), 30-day all-cause readmission rate of UC from 14.1% in 2010 to 15.7% in 2018 (P-trend = 0.003), and UC specific readmission rate from 5.2% in 2010 to 5.6% in 2018 (P-trend = 0.029). There was no change in the risk adjusted trends of inpatient mortality and mean LOS for CD and UC readmissions. However, we found an increasing trend of mean THC for UC readmissions. After comparison, there was no statistical difference in the trends for 30 d all-cause readmission rate, inpatient mortality, and mean LOS between CD and UC readmissions. Conclusion: There was an increase in total number of 30 d readmissions for CD and UC with a trend towards increasing 30 d all-cause readmission rates.Item Obese gastroparesis inpatient admissions: trends and outcomes from 2007-2017 in the United States(Hellenic Society of Gastroenterology, 2022) Dahiya, Dushyant S.; Perisetti, Abhilash; Al-Haddad, Mohammad; Kichloo, Asim; Sharma, Rahul; Cheng, Chin-I; Inamdar, Sumant; Medicine, School of MedicineBackground: The aim of this study was to investigate obese gastroparesis (GP) hospitalizations in the United States (US). Methods: We analyzed the National Inpatient Sample (NIS) from 2007-2017 to identify all adult obese (body mass index ≥30 kg/m2) GP hospitalizations. These were compared with non-obese GP hospitalizations. The demographic trends, adverse outcomes, and healthcare burden were analyzed. Results: From 2007-2017, obese GP hospitalizations accounted for 13.75% of all GP hospitalizations in the US. There was an increasing trend in obese GP hospitalizations, from 2286 in 2007 to 47,265 in 2017 (P=0.0019), and in the proportion of obese GP hospitalizations, from 6.16% in 2007 to 17.96% in 2017 (P<0.001). Males, Blacks, Hispanics, and Asians showed a rising trend in obese GP hospitalizations. Although rates of upper endoscopy declined from 8.28% in 2007 to 5.36% in 2017 (P<0.001), obese GP hospitalizations had higher rates of upper endoscopy utilization (6.05 vs. 5.42%, P<0.001) compared to the non-obese cohort. Inpatient mortality for obese GP hospitalizations increased from 0.64% in 2007 to 1.10% in 2017 (P<0.001). Furthermore, we noted a rising trend in mean length of stay (LOS), from 4.64 in 2007 to 6.05 days in 2017 (P=0.0029), and mean total hospital charge (THC), from $22,306 in 2007 to $62,220 in 2017 (P<0.001) for obese GP hospitalizations. Conclusions: The prevalence of obese GP hospitalizations along with inpatient mortality, LOS, and THC rose significantly. However, the overall rate of upper endoscopy utilization has decreased for these patients.Item Peptic ulcer disease in non-alcoholic fatty liver disease hospitalizations: A new challenge on the horizon in the United States(Baishideng, 2023) Dahiya, Dushyant Singh; Jahagirdar, Vinay; Ali, Hassam; Gangwani, Manesh Kumar; Aziz, Muhammad; Chandan, Saurabh; Singh, Amandeep; Perisetti, Abhilash; Soni, Aakriti; Inamdar, Sumant; Sanaka, Madhusudhan R.; Al-Haddad, Mohammad; Medicine, School of MedicineBackground: Peptic ulcer disease (PUD) is frequently seen in patients with liver cirrhosis. However, current literature lacks data on PUD in non-alcoholic fatty liver disease (NAFLD) hospitalizations. Aim: To identify trends and clinical outcomes of PUD in NAFLD hospitalizations in the United States. Methods: The National Inpatient Sample was utilized to identify all adult (≥ 18 years old) NAFLD hospitalizations with PUD in the United States from 2009-2019. Hospitalization trends and outcomes were highlighted. Furthermore, a control group of adult PUD hospitalizations without NAFLD was also identified for a comparative analysis to assess the influence of NAFLD on PUD. Results: The total number of NAFLD hospitalizations with PUD increased from 3745 in 2009 to 3805 in 2019. We noted an increase in the mean age for the study population from 56 years in 2009 to 63 years in 2019 (P < 0.001). Racial differences were also prevalent as NAFLD hospitalizations with PUD increased for Whites and Hispanics, while a decline was observed for Blacks and Asians. The all-cause inpatient mortality for NAFLD hospitalizations with PUD increased from 2% in 2009 to 5% in 2019 (P < 0.001). However, rates of Helicobacter pylori (H. pylori) infection and upper endoscopy decreased from 5% in 2009 to 1% in 2019 (P < 0.001) and from 60% in 2009 to 19% in 2019 (P < 0.001), respectively. Interestingly, despite a significantly higher comorbidity burden, we observed lower inpatient mortality (2% vs 3%, P = 0.0004), mean length of stay (LOS) (11.6 vs 12.1 d, P < 0.001), and mean total healthcare cost (THC) ($178598 vs $184727, P < 0.001) for NAFLD hospitalizations with PUD compared to non-NAFLD PUD hospitalizations. Perforation of the gastrointestinal tract, coagulopathy, alcohol abuse, malnutrition, and fluid and electrolyte disorders were identified to be independent predictors of inpatient mortality for NAFLD hospitalizations with PUD. Conclusion: Inpatient mortality for NAFLD hospitalizations with PUD increased for the study period. However, there was a significant decline in the rates of H. pylori infection and upper endoscopy for NAFLD hospitalizations with PUD. After a comparative analysis, NAFLD hospitalizations with PUD had lower inpatient mortality, mean LOS, and mean THC compared to the non-NAFLD cohort.
