Rising Readmission Rates After Diabetic Ketoacidosis Hospitalization Among Adults With Type 1 Diabetes Throughout a Decade in the United States.

Research on longitudinal trends in readmission rates after diabetic ketoacidosis (DKA) is lacking. This retrospective study was aimed at identifying trends in readmissions after hospitalization for DKA, as well as trends in outcomes after readmission, over time among adults with type 1 diabetes in the United States. Findings indicate that the DKA readmission rate increased from 53 to 73 events per 100,000 between 2010 to 2018, and low-income and uninsured patients had higher odds of readmission. There was no significant change in mortality after readmission over time. Improved access to care and affordable management options may play a crucial role in preventing readmissions.

Endoscopic Retrograde Cholangiopancreatography (ERCP) in Patients With Liver Cirrhosis: Analysis of Trends and Outcomes From the National Inpatient Sample Database.

GOALS: We aimed to assess outcomes of patients with liver cirrhosis who underwent therapeutic or diagnostic endoscopic retrograde cholangiopancreatography (ERCP) to determine whether these patients had different outcomes relative to patients without cirrhosis. BACKGROUND: ERCP is an important procedure for treatment of biliary and pancreatic disease. However, ERCP is relatively technically difficult to perform when compared with procedures such as esophagogastroduodenoscopy or colonoscopy. Little is known about how ERCP use affects patients with liver cirrhosis. STUDY: Using patient records from the National Inpatient Sample (NIS) database, we identified adult patients who underwent ERCP between 2009 and 2014 using International Classification of Disease, Ninth Revision coding and stratified data into 2 groups: patients with liver cirrhosis and those without liver cirrhosis. We compared baseline characteristics and multiple outcomes between groups and compared outcomes of diagnostic versus therapeutic ERCP in patients with cirrhosis. A multivariate regression model was used to estimate the association of cirrhosis with ERCP outcomes. RESULTS: A total of 1,038,258 hospitalizations of patients who underwent ERCP between 2009 and 2014 were identified, of which 31,294 had cirrhosis and 994,681 did not have cirrhosis. Of the patients with cirrhosis, 21,835 (69.8%) received therapeutic ERCP and 9459 (30.2%) received diagnostic ERCP. Patients with cirrhosis had more ERCP-associated hemorrhages (2.5% vs. 1.2%; P <0.0001) compared with noncirrhosis patients but had lower incidence of perforations (0.1% vs. 0.2%; P <0.0001) and post-ERCP pancreatitis (8.6% vs. 7%; P <0.0001). Cholecystitis was the same between groups (2.3% vs. 2.3%; P <0.0001). In patients with cirrhosis, those who received therapeutic ERCP had higher post-ERCP pancreatitis (7.9% vs. 5.1%; P <0.0001) and ERCP-associated hemorrhage (2.7% vs. 2.1%; P <0.0001) but lower incidences of perforation and cholecystitis (0.1% vs. 0.3%; P <0.0001) and cholecystitis (1.9 vs. 3.1%; P <0.0001) compared with those who received diagnostic ERCP. CONCLUSIONS: Use of therapeutic ERCP in patients with liver cirrhosis may lead to higher risk of complications such as pancreatitis and postprocedure hemorrhage, whereas diagnostic ERCP may increase the risk of pancreatitis and cholecystitis in patients with cirrhosis. Comorbidities in cirrhosis patients may increase the risk of post-ERCP complications and mortality; therefore, use of ERCP in cirrhosis patients should be carefully considered, and further studies on this patient population are needed.

Thirty-Day Hospital Readmissions for Acute Gout in the United States: Analysis of the Nationwide Readmission Database.

BACKGROUND/OBJECTIVE: The aims of this study were to describe the rates and characteristics of nonelective 30-day readmission among adult patients hospitalized for acute gout and to assess predictors of readmission. METHODS: We analyzed the 2017 Nationwide Readmission Database. Gout hospitalizations were identified using the International Classification of Diseases, Tenth Revision, Clinical Modification code. Hospitalizations for adult patients were included. We excluded planned or elective readmissions. We utilized χ2 tests to compare baseline characteristics between readmissions and index hospitalizations. We used multivariate Cox regression to identify independent predictors of readmissions. RESULTS: A total of 11,727 index adult hospitalizations with acute gout listed as the principal diagnosis were discharged alive and included. One thousand five hundred ninety-four (13.6%) readmissions occurred within 30 days. Acute gout was the most common reason for readmission. Readmissions had higher inpatient mortality (2.4% vs 0.1%, p < 0.0001), greater mean age (68.1 vs 67.0 years, p = 0.021), and longer hospital length of stay (5.9 vs 3.8 days, p < 0.0001) compared with index hospitalizations. Charlson Comorbidity Index scores of ≥2 (score 2: adjusted hazards ratio [AHR], 1.67; p = 0.001; score ≥3: AHR, 2.08; p < 0.0001), APR-DRG (All Patients Refined Diagnosis Related Groups) severity levels ≥2 (level 2: AHR, 1.43; p = 0.044; level 3: AHR, 1.83; p = 0.002; level 4: AHR, 2.38; p = 0.002), admission to metropolitan hospital (AHR, 1.83; p = 0.012), atrial fibrillation (AHR, 1.31; p = 0.004), and anemia (AHR, 1.30; p = 0.001) were significantly associated with 30-day readmissions. CONCLUSIONS: Acute gout readmissions were associated with worse outcomes compared with index hospitalizations. Charlson Comorbidity Index scores ≥2, APR-DRG severity levels ≥2, admission to metropolitan hospital, atrial fibrillation, and anemia were significant predictors of readmission.

Predictors of 30-day readmissions for adrenal insufficiency: A retrospective national database study.

OBJECTIVE: The aim of this study was to describe rates and characteristics of non-elective 30-day readmission among patients hospitalized for adrenal insufficiency and to assess predictors of readmission. DESIGN: We analysed the 2018 National Readmission Database. Adrenal insufficiency hospitalizations were identified using the International Classification of Diseases, Tenth Revisions, Clinical Modification diagnosis codes for principal diagnostic codes of primary adrenal insufficiency, Addisonian crisis, drug-induced adrenocortical insufficiency, and other and unspecified adrenocortical insufficiency. PATIENTS: During the study period, 7738 index hospitalizations were identified as patients with AI who met the inclusion criteria. Of these, 7691 were discharged alive. MEASUREMENTS: We utilized chi-squared tests to compare baseline characteristics between readmissions and index hospitalizations. Multivariate Cox regression was used to identify independent predictors of readmission. RESULTS: The 30-day all-cause readmission rate for AI was 17.3%. About 1 in 5 readmissions was for AI. Other reasons for readmission included sepsis (10.8%), unspecified pneumonia (3.1%) and acute renal failure unspecified (1.6%). Readmission was associated with significantly higher odds of inpatient mortality. Independent predictors of 30-day all-cause readmissions included index hospitalizations with the Charlson Comorbidity Index (CCI) ≥3 (adjusted hazards ratio (aHR): 2.53, 95% CI: 1.85-3.46, p < .001), protein-energy malnutrition (aHR: 1.28, 95% CI: 1.02-1.60, p = .035) and obesity (aHR: 1.26, 95% CI: 1.02-1.56, p = .035). CONCLUSIONS: The 30-day all-cause readmission rate was 17.3%. AI was the most common reason for readmission among other causes. Readmissions were associated with increased mortality. CCIs of 3 or more, protein-energy malnutrition and obesity were significant predictors of readmission.

Implantable cardiac devices in geriatric patients: a primer for primary and geriatric physicians.

In the next 20 years, the percentage of people older than 65 years of age in the United States is expected to double. Heart disease is the leading cause of mortality in developed nations, including the United States. Due to the increased incidence of cardiac disease in elderly patients, the need for special treatment considerations, including cardiac devices, may be necessary to reduce morbidity and mortality in this patient population. The purpose of this review is to provide a primer of the common cardiac devices used in the management of cardiac disorders in the geriatric patient population. In order to do this, we have performed a literature review for articles related to cardiac devices published between 2000 and 2020, in addition to reviewing guidelines and recommendations from relevant professional societies. We provide readers with an overview of several cardiac devices including implantable loop recorders, pacemakers, cardiac resynchronization therapy, automated implantable cardiac defibrillators, watchman devices, and ventricular assist devices. Indications, contraindications, clinical trial data, and general considerations in the geriatric population were included. Due to the aging population and increased incidence of cardiac disease, clinicians should be aware of the indications and contraindications of cardiac device therapy in the management of various cardiac conditions that afflict the geriatric population.

Comparing outcomes of diabetic ketoacidosis hospitalisations in patients with diastolic heart failure: A retrospective propensity matched analysis of the nationwide inpatient sample.

INTRODUCTION: Diabetic ketoacidosis (DKA) is a known complication of patients with diabetes mellitus. The aim of this study was to compare the outcomes of patients admitted with a diagnosis of DKA with, and without, diastolic heart failure (DHF). METHODS: This was a population-based, retrospective, observational study using data from the National Inpatient Sample database for the years 2016 and 2017. The primary outcome was in-hospital mortality. Secondary outcomes were rates of sepsis, non-ST elevation myocardial infarctions (NSTEMI), acute kidney failure, acute respiratory failure (ARF), deep vein thrombosis, pulmonary embolism, mean length of hospital stay (LOS) and total hospital charges (THC). RESULTS: There was no statistically significant difference for the adjusted odds for in-hospital mortality between patients with and without DHF (adjusted odds ratio [aOR]: 0.55, 95% confidence interval [CI] 0.28-1.08, p = 0.081). Patients with DKA and DHF had increased odds of developing an NSTEMI (aOR: 1.31, 95% CI: 1.01-1.70, p = 0.045) or ARF (aOR: 1.82, 95% CI: 1.38-2.40, p < 0.001) during the same admission compared to patients without DHF. Patients with DKA and DHF also had an increased mean THC (6500 CI: 1900-11,200, p = 0.0006) in US dollars and increased LOS (0.7, 95% CI: 0.2-1.3, p = 0.011) in days when compared to patients without DHF. CONCLUSIONS: Patients with DKA showed no statistically significant difference in mortality if they did or did not have a secondary diagnosis of DHF within the same admission.

Predictors of outcomes in hospitalized patients undergoing pacemaker insertion: Analysis from the national inpatient database (2016-2017).

BACKGROUND: Pacemaker implantation in the U.S. is rising due to an aging population. The aim of this analysis was to identify risk factors associated with increased mortality and complications in hospitalized patients requiring pacemaker implantation. METHODS: We performed a retrospective analysis using the National Inpatient Sample database, identifying hospitalized patients who underwent pacemaker implantation using International Classification of Disease, Tenth Revision, Clinical Modification codes. Independent predictors of inpatient mortality were identified using multivariate logistic regression analysis. RESULTS: There were 242,980 hospitalizations with pacemaker implantation during 2016 and 2017. The most frequently encountered indications for hospitalizations involving pacemaker insertion included sick sinus syndrome (SSS) (27.60%), complete atrioventricular (AV) block (21.57%), and second-degree AV block (7.83%). Chronic liver disease was associated with the highest adjusted odds of inpatient mortality (aOR = 5.76, 95% CI: 4.46 to 7.44, p < .001). Comorbid anemia had the highest statistically significant adjusted odds ratio (aOR) for predictors of post-procedural cardiac complications (aOR = 3.17, 95% CI: 2.81 to 3.58, p < .001). Mortality in hospitalized patients needing pacemaker implantation was 1.05%. About 3.36% of hospitalizations developed post procedural circulatory complications (PPCC), 2.45% developed sepsis, and 1.84% developed mechanical complications of cardiac electronic devices. CONCLUSIONS: We identified several predictors of inpatient mortality in hospitalized patients undergoing pacemaker implantation, including chronic liver disease, protein-calorie malnutrition, chronic heart failure, anemia, and history of malignancy. Anemia, chronic liver disease, and congestive heart failure were independent predictors of adverse outcomes in such patients.

Association of hypocalcemia with in-hospital mortality and complications in patients with acute pulmonary embolism: results from the 2017 Nationwide Inpatient Sample.

BACKGROUND: Acute pulmonary embolism (PE) is a common cause for hospitalization associated with significant mortality and morbidity. Disorders of calcium metabolism are a frequently encountered medical problem. The effect of hypocalcemia is not well defined on the outcomes of patients with PE. We aimed to identify the prognostic value of hypocalcemia in hospitalized PE patients utilizing the 2017 Nationwide Inpatient Sample (NIS). METHODS: In this retrospective study, we selected patients with a primary diagnosis of Acute PE using ICD 10 codes. They were further stratified based on the presence of hypocalcemia. We primarily aimed to compare in-hospital mortality for PE patients with and without hypocalcemia. We performed multivariate logistic regression analysis to adjust for potential confounders. We also used propensity-matched cohort of patients to compare mortality. RESULTS: In the 2017 NIS, 187,989 patients had a principal diagnosis of acute PE. Among the above study group, 1565 (0.8%) had an additional diagnosis of hypocalcemia. 12.4% of PE patients with hypocalcemia died in the hospital in comparison to 2.95% without hypocalcemia. On multivariate regression analysis, PE and hypocalcemia patients had 4 times higher odds (aOR-4.03, 95% CI 2.78-5.84, p < 0.001) of in-hospital mortality compared to those with only PE. We observed a similarly high odds of mortality (aOR = 4.4) on 1:1 propensity-matched analysis. The incidence of acute kidney injury (aOR = 2.62, CI 1.95-3.52, p < 0.001), acute respiratory failure (a0R = 1.84, CI 1.42-2.38, p < 0.001), sepsis (aOR = 4.99, CI 3.08-8.11, p < 0.001) and arrhythmias (aOR = 2.63, CI 1.99-3.48, p < 0.001) were also higher for PE patients with hypocalcemia. CONCLUSION: PE patients with hypocalcemia have higher in-hospital mortality than those without hypocalcemia. The in-hospital complications were also higher, along with longer length of stay.

Increased inpatient mortality in patients hospitalized for atrial fibrillation and atrial flutter with concomitant amyloidosis: Insight from National Inpatient Sample (NIS) 2016-2017.

PURPOSE: Using National Inpatient Database (NIS), comparison of clinical outcomes for patients primarily admitted for atrial fibrillation/flutter with and without a secondary diagnosis of amyloidosis was done. Inpatient mortality was the primary outcome and hospital length of stay (LOS), mean total hospital charges, odds of undergoing cardiac ablation, pharmacologic cardioversion, having a secondary discharge diagnosis of heart block, cardiogenic shock and cardiac arrest were secondary outcomes. METHODS: NIS database of 2016, 2017 was used for only adult hospitalizations with atrial fibrillation/flutter as principal diagnosis with and without amyloidosis as secondary diagnosis using ICD-10 codes. Multivariate logistic with linear regression analysis was used to adjust for confounders. RESULTS: 932,054 hospitalizations were for adult patients with a principal discharge diagnosis of atrial fibrillation/flutter. 830 (0.09%) of these hospitalizations had amyloidosis. Atrial fibrillation/flutter hospitalizations with co-existing amyloidosis have higher inpatient mortality (4.22% vs 0.88%, AOR: 3.92, 95% CI 1.81-8.51, p = 0.001) and likelihood of having a secondary discharge diagnosis of cardiac arrest (2.40% vs 0.51%, AOR: 4.80, 95% CI 1.89-12.20, p = 0.001) compared to those without amyloidosis. CONCLUSIONS: Hospitalizations of atrial fibrillation/flutter with co-existing amyloidosis have higher inpatient mortality and odds of having a secondary discharge diagnosis of cardiac arrest compared to those without amyloidosis. However, LOS, total hospital charges, likelihood of undergoing cardiac ablation, pharmacologic cardioversion, having a secondary discharge diagnosis of heart block and cardiogenic shock were similar between both groups.

Cirrhosis: Primary care approaches to screening, immunization, and lifestyle modifications.

For patients with decompensated cirrhosis, health maintenance is critical to improve survival rates and prevent adverse outcomes. We review the primary care management of cirrhosis and its complications, such as esophageal varices, hepatocellular carcinoma, and chemical or medication exposures. We also highlight specific immunizations and lifestyle modifications to prevent decompensation, and we summarize current screening guidelines.

Hospitalizations for ketoacidosis in type 1 diabetes mellitus, 2008 to 2018.

The objective of this study was to characterize epidemiological trends, outcomes in hospitalized patients, and the disease burden of hospitalizations for diabetic ketoacidosis (DKA) in patients with type 1 diabetes mellitus (T1DM). This was a retrospective interrupted trends study involving hospitalizations for DKA in patients with T1DM in the US from 2008 to 2018 using data from the Nationwide Inpatient Sample. The total number of hospitalizations during each calendar year was obtained, and trends in inpatient mortality rate, mean length of hospital stay (LOS), and mean total hospital cost (THC) were calculated. Between 2008 and 2018, there was a trend toward increasing hospitalizations for T1DM with DKA (P-trend <0.001). Over the decade, there was a steady rise in the proportion of patients with a Charlson comorbidity index >1. There was no statistically significant change in adjusted inpatient mortality in patients with T1DM admitted for DKA over the study period despite an apparent trend of a decreasing crude mortality rate (P-trend = 0.063). There was a statistically significant decrease in both LOS and THC over the study period. In conclusion, there was a significant decrease in both LOS and THC, potentially reflecting improvements in the management of DKA in patients with T1DM.

Radiation Proctitis and Management Strategies.

Radiotherapy (RT) is a treatment modality that uses high-energy rays or radioactive agents to generate ionizing radiation against rapidly dividing cells. The main objective of using radiation in cancer therapy is to impair or halt the division of the tumor cells. Over the past few decades, advancements in technology, the introduction of newer methods of RT, and a better understanding of the pathophysiology of cancers have enabled physicians to deliver doses of radiation that match the exact dimensions of the tumor for greater efficacy, with minimal exposure of the surrounding tissues. However, RT has numerous complications, the most common being radiation proctitis (RP). It is characterized by damage to the rectal epithelium by secondary ionizing radiation. Based on the onset of signs and symptoms, post-radiotherapy RP can be classified as acute or chronic, each with varying levels of severity and complication rates. The treatment options available for RP are limited, with most of the data on treatment available from case reports or small studies. Here, we describe the types of RT used in modern-day medicine and radiation-mediated tissue injury. We have primarily focused on the classification, epidemiology, pathogenesis, clinical features, treatment strategies, complications, and prognosis of RP.

Ten-year trends in adrenal insufficiency admissions.

Adrenal insufficiency (AI) is a severe disease that is difficult to manage in both inpatient and outpatient settings. This study describes trends, inpatient outcomes, and the disease burden of hospitalizations for patients with AI. Data are included on hospitalizations with a principal discharge diagnosis of AI using ICD codes from the National Inpatient Sample for the years 2008, 2010, 2012, 2014, 2016, and 2018. Patients <18 years and those with elective hospitalizations were excluded. From 2008 to 2018, the number of AI hospitalizations increased significantly (P-trend < 0.001), with a rising trend in the proportion of patients with Charlson Comorbidity Index scores >3. There was a significant downward trend in the length of stay from 2008 to 2018 (P-trend = 0.005). However, there was no statistically significant trend for mortality or mean total hospital charges during hospitalizations (P-trend = 0.050 and 0.076, respectively). In conclusion, AI hospitalizations significantly increased over the 10 years with an overall decrease in length of stay.

A decade of hospitalizations for hyperthyroidism in the US.

The goal of this study was to examine healthcare burden, hospitalizations, mortality, and healthcare cost utilization from hyperthyroidism to further our understanding of the effect of changes in thyroid disease management over the past decade. This was a retrospective longitudinal trends study involving hospitalizations for hyperthyroidism in the US from 2008 to 2018. We trended crude hospitalization rate, estimated incidence of hospitalizations, trends in inpatient mortality rate, mean length of hospital stay, and mean total hospital cost of patients with hyperthyroidism. The number of hyperthyroid hospitalizations decreased from 12,689 in 2008 to 9110 in 2018 (28.2%) (P trend <0.001), with a decrease of crude hospitalization rate from 33 to 25 per 100,000 hospitalizations. The estimated incidence rate of hospitalization in patients with hyperthyroidism decreased from 441 to 288 per 100,000 adults with hyperthyroidism. There was, however, no difference in adjusted mortality in hospitalizations over the study period. Although there has been a significant reduction in hospitalizations due to hyperthyroidism in the US, there has been no significant change in mortality during hospitalizations. This may represent improving outpatient management of hyperthyroidism. However, this improvement has not translated to outcomes in the hospital setting.

A nationwide analysis on the influence of obesity in inflammatory bowel disease hospitalizations.

BACKGROUND/AIMS: Proinflammatory cytokines released from adipocytes can influence the development, progression, and treatment of inflammatory bowel disease (IBD), and may be associated with worse clinical outcomes. METHODS: For 2016-2018, we analyzed data from the Nationwide Inpatient Sample to identify adult (≥18 years) hospitalizations with a primary discharge diagnosis of IBD. The study sample was divided based on the presence or absence of obesity. The primary outcomes included inpatient mortality, while the secondary outcomes consisted of system-based complications and disease implications on the United States healthcare system. RESULTS: We identified 282,005 hospitalizations of IBD from 2016 to 2018. Of these hospitalizations, 26,465 (9.4%) had a secondary diagnosis of obesity while 255,540 (90.6%) served as controls. IBD hospitalizations with obesity had a higher mean age (47.9 years vs. 45.2 years, P<0.001), middle age (range, 40-65 years) predominance (37.7% vs. 28.9%, P<0.001), female predominance (64.1% vs. 52.5%, P<0.001) and higher proportion of patients with comorbidities compared to the non-obese cohort. White predominance was observed in both subgroups. No difference in the odds of inpatient mortality was noted between the 2 subgroups; however, IBD hospitalizations with obesity had higher mean total hospital charge ($50,126 vs. $45,001, P<0.001), longer length of stay (5.5 days vs. 4.9 days, P<0.001) and higher proportion of complications compared to the non-obese cohort. CONCLUSIONS: Obese IBD hospitalizations had higher length of stay, total hospital charge, and complications compared to the non-obese cohort.

A nationwide retrospective analysis of ventilator-associated pneumonia in the US.

Ventilator-associated pneumonia (VAP) is a major cause of healthcare-associated mortality and morbidity in critically ill patients who are mechanically ventilated. The purpose of this study was to describe the various primary discharge diagnoses of hospitalizations with VAP, to identify their demographic characteristics, and to identify risk factors for mortality in hospitalizations with VAP. Hospitalizations with a diagnosis of VAP with mechanical ventilation for over 24 hours were selected from the National Inpatient Sample in 2016 and 2017. In total, 33,140 hospitalizations with VAP were analyzed. The leading principal discharge diagnoses for hospitalizations leading to VAP were sepsis due to an unspecified organism (16.92%), respiratory failure (8.09%), and VAP (6.38%). Mortality among hospitalizations with VAP was 20.9%. Independent risk factors for mortality in hospitalizations with VAP were uninsured status (adjusted odds ratio [aOR] 2.13, 95% confidence interval [CI] 1.49-3.06, P < 0.001), acute renal failure (aOR 2.00, 95% CI 1.75-2.30, P < 0.001), and liver disease (aOR 1.82, 95% CI 1.52-2.18, P < 0.001). In conclusion, VAP is associated with significant mortality. Infective, traumatic, cardiovascular, and respiratory conditions accounted for over 85% of hospitalizations with VAP. Acute renal failure, the presence of liver disease, and lack of insurance are associated with higher mortality in hospitalizations with VAP.

Hyperammonemia in lung transplant patients and its management: a review.

Objective: To synthesize the evidence for incidence, pathophysiology, etiology, and protocol-based management of hyperammonemia in lung transplant patients. Background: Elevated ammonia levels are toxic to the brain, and hyperammonemia results in a potentially fatal complication for lung transplant recipients. The hallmark of this condition is ammonia production being way out of proportion to the degree of liver derangement. While there are many hypotheses, the cause remains obscure. Methods: A retrospective review of patients with hyperammonemia following lung transplantation was done to understand the pathophysiology, various treatment modalities, and its impact on patient mortality and morbidity. Studies in the English literature were identified through an electronic database search from PubMed/MEDLINE, Ovid Embase, Google Scholar, Cochrane Database of Systematic Reviews (CDSR), Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, Web of Science, and ClinicalTrials.gov until June 2020. No restriction of dates were used, and the search was up until June 2020. Discussion: Mortality among patients with hyperammonemia following lung transplantation is high. Multi-modal treatment approaches include avoiding nephrotoxic drugs, use of bowel decontamination, nitrogen scavengers, branched-chain amino acids, adjustment of immunosuppression, antibiotics like fluoroquinolones or azithromycin, and renal replacement therapy. However, there remains a scarcity of preoperative screening protocol for patients at risk of hyperammonemia as well evidence-based post-operative management guidelines. Intermittent hemodialysis, compared to continuous venovenous hemodialysis, provides better patient outcomes. Conclusion: Early detection of patients at risk by appropriate screening, along with maintaining a high degree of suspicion for hyperammonemia and multi-modal treatment approach, is the key to successful patient outcomes. Further prospective observational studies would facilitate development of protocol-based treatment of this potentially fatal condition.

Hospitalizations and inpatient mortality for hyperosmolar hyperglycemic state over a decade.

OBJECTIVES: This study aimed to describe rates and trends in hospitalizations, inpatient mortality, total hospital charges, and mean lengths of stay among adult patients hospitalized for hyperosmolar hyperglycemic state (HHS). METHODS: The study included NIS databases 2008, 2010, 2012, 2014, 2016, and 2018. These databases were searched for hospitalizations with a principal discharge diagnosis of HHS in patients with T2DM using ICD codes (25020, 25022, and E110). Patients less than 18 years, elective hospitalizations, HHS in patients with T1DM or secondary diabetes mellitus were excluded. We used multivariable regression analysis to obtain trends in mortality, length of stay (LOS), and total hospital charges (THC). RESULTS: Between 2008 and 2018, there was a trend towards increasing hospitalizations for T2DM with HHS (p trend < 0.001). The mean age over the period ranged from 56.9 to 59.1 years old. Men made up the majority of hospitalizations. Over the decade, there was a steady rise in the proportion of Whites and Hispanics with HHS, and Medicare was the most prevalent insurer overall. Inpatient mortality for HHS decreased from 1.44% in 2008 to 0.77% in 2018 (p trend 0.007). There was also a statistically significant decrease in both LOS and THC over the studied period. CONCLUSIONS: Trends in HHS showed increased hospitalizations, LOS, and THC over the decade in the study period, but inpatient mortality declined.
