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.

Successful Treatment of Recurrent Colonic Adenocarcinoma with Metastatic Tumor Thrombus in the Superior Mesenteric Vein with Surgical Excision and Venous Reconstruction.

BACKGROUND Patients cured of Hodgkin lymphoma (HL) are at increased risk of second malignancies, such as lung, breast, and colon cancer. Isolated metastasis of these malignancies to the vasculature is rare. We present a unique case of a patient cured of HL who developed colon cancer and later presented with an isolated metastases of colon cancer to the superior mesenteric vein. The patient is now in complete remission 5 years after surgical excision of the superior mesenteric vein metastases followed by chemotherapy. CASE REPORT A 56-year-old woman presented with a past medical history notable for stage III HL diagnosed at age 13 years that was treated by splenectomy, chemotherapy, and mantle with inverted Y radiation. She underwent a right nephrectomy at age 51 years for renal cell carcinoma. At age 56, an 8-cm mass in the transverse colon was found during surveillance imaging. She underwent right hemicolectomy for pathological stage IIA (T3N0M0) adenocarcinoma. A liver adenoma was identified a year later. Two years after hemicolectomy, an abdominal recurrence was identified, and she underwent a resection of a superior mesenteric vein mass with porto-mesenteric reconstruction. Pathology revealed metastatic colonic adenocarcinoma, 1 of 7 lymph nodes positive for cancer, and clear margins. She received 6 months of fluorouracil chemotherapy and remained free of recurrences for 5 years. CONCLUSIONS Isolated vascular recurrences of colon cancer can be cured with resection and systemic chemotherapy. Diagnosis and treatment of venous recurrences remains challenging owing to the lack or percutaneous access for biopsy and the difficulty of venous reconstruction.

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.

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.

Plasmapheresis in hypertriglyceridemia-induced acute pancreatitis.

The study involved hospitalizations with a diagnosis of hypertriglyceridemia-induced acute pancreatitis (HTGAP). This cohort was grouped into plasmapheresis and nonplasmapheresis groups using ICD-10 codes (6A550Z3 and 6A551Z3). Information was obtained on inpatient mortality, length of stay, total hospital charges, as well as the occurrence of comorbid systemic immune response syndrome, sepsis, septic shock, acute respiratory failure, acute respiratory distress syndrome, kidney failure, hypocalcemia, and need for transfusion of blood products. The study identified independent predictors of plasmapheresis. The plasmapheresis group had a higher proportion of patients with diabetes mellitus and obesity. Inpatient mortality was higher in the plasmapheresis group (0.86% vs 0.57%), and plasmapheresis was also associated with longer length of stay and higher total hospital charges. Overall, plasmapheresis was associated with higher proportions of inpatient complications. Patients with HTGAP had higher odds of undergoing plasmapheresis if they were in an urban location (adjusted odds ratio [aOR] 6.14, 95% confidence Interval [CI] 1.86-20.28, P = 0.003), larger hospital (aOR 3.37, 95% CI 2.14-5.29, P < 0.001), and teaching hospital (aOR 2.01, 95% CI 1.39-2.92, P < 0.001). Black patients were less likely to undergo plasmapheresis than white patients (aOR 0.42, 95% CI 0.23-0.78, P = 0.006). Patients with HTGAP who receive plasmapheresis may be at higher risk of numerous in-hospital complications, including death, compared to those who do not receive plasmapheresis. Black and older patients were less likely to undergo plasmapheresis.

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.

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.

Clinical Outcomes and Predictors of Thirty-Day Readmissions of Hypertriglyceridemia-Induced Acute Pancreatitis.

Background: Hypertriglyceridemia (HTG) is a well-established cause of acute pancreatitis often leading to significant morbidity, mortality, and healthcare burden. This study aimed to describe the rate, reasons, and predictors of HTG-induced acute pancreatitis (HTG-AP) in the USA. Methods: This retrospective study analyzed the Nationwide Readmissions Database (NRD) for 2018 to determine all adults (≥ 18 years) readmitted within 30 days of an index hospitalization of HTG-AP. Hospitalization characteristics and adverse outcomes for 30-day readmissions were highlighted and compared with index admissions of HTG-AP. Furthermore, independent predictors for 30-day readmissions of HTG-AP were also identified. P values ≤ 0.05 were considered statistically significant. Results: In 2018, the rate of 30-day readmission of HTG-AP was noted to be 13.5%. At the time of readmission, AP (45.2%) was identified as the most common principal diagnosis, followed by chronic pancreatitis (6.3%) and unspecified sepsis (4.8%). Compared to index admissions, 30-day readmissions of HTG-AP had a higher proportion of patients with Charlson Comorbidity Index (CCI) scores ≥ 3 (48.5% vs. 33.8%, P < 0.001). Furthermore, we noted higher rates of inpatient mortality (1.7% vs. 0.7%, odds ratio (OR): 2.55, 95% confidence interval (CI): 1.83 - 3.57, P < 0.001), mean length of stay (LOS) (5.6 vs. 4.1 days, OR: 1.5, 95% CI: 1.2 - 1.7, P < 0.001), and mean total healthcare charge (THC) ($56,799 vs. $36,078, OR: 18,702, 95% CI: 15,136 - 22,267, P < 0.001) for 30-day readmissions of HTG-AP compared to index admissions. Independent predictors for 30-day all-cause readmissions of HTG-AP included hypertension, protein energy malnutrition (PEM), CCI scores ≥ 3, chronic kidney disease and discharge against medical advice. Conclusions: AP was the principal diagnosis on presentation in only 45.2% patients for 30-day readmissions of HTG-AP. Compared to index admissions, 30-day readmissions of HTG-AP had a higher comorbidity burden, inpatient mortality, mean LOS and mean THC.

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.

Rate and predictors of 30-day readmission for clostridiodes difficile: a United States analysis.

BACKGROUND: Clostridiodes difficile is a leading cause of healthcare-associated diarrhea. In this study, we aimed to identify the rates and predictors for 30-day readmissions of Clostridiodes difficile Enterocolitis (CDE) in the United States. METHODS: We conducted a retrospective study of the Nationwide Readmissions Database to identify adult hospitalizations with a principal diagnosis of CDE for 2018. Individuals <18 years old and elective hospitalizations were excluded. Primary outcomes included readmission rate and the top ten principal diagnosis on readmission, while the secondary outcomes were inpatient mortality, hospital costs and independent predictors of 30-day all-cause readmissions. Furthermore, we devised a scoring system to estimate the risk of CDE readmissions. Stata® Version 16 was used for statistical analysis and p-values ≤0.05 were statistically significant. RESULTS: We identified 94,668 index hospitalizations and 18,296 readmissions at 30-days for CDE in 2018. The 30-day all-cause readmission rate was 25.7%. On readmission, CDE was the most common principal diagnosis (25.7%), followed by unspecified sepsis, and acute renal failure. A female predominance was also noted for index and 30-day readmissions of CDE. Compared to index admissions, we noted higher odds of inpatient mortality [4.4 vs 1.4%, Odds Ratio (OR):3.32, 95% Confidence Interval (CI):2.87-3.84, p < 0.001], longer mean length of stay (LOS) [6.4 vs 5.6 days, Mean Difference (MD):0.9, 95% CI:0.7-1.0, p < 0.001), and higher mean total hospital charge (THC) [$56,015 vs $40,871, MD:15,144, 95% CI:13,260-17,027, p < 0.001] for 30-day readmissions of CDE. Independent predictors for 30-day all-cause readmissions of CDE included discharged against medical advice (AMA) [Adjusd Hazard Ratio (aHR):2.01, 95% CI:1.73-2.53, p < 0.001], diabetes mellitus (DM) [aHR:1.22, 95% CI:1.16-1.29, p < 0.001], and chronic kidney disease (CKD) [aHR:1.29, 95% CI:1.21-1.37, p < 0.001]. CONCLUSION: The all-cause 30-day readmission rate and inpatient mortality for CDE was 25.7% and 4.4%, respectively. Discharge AMA, DM and CKD were independent predictors for 30-day all-cause readmissions of CDE.KEY MESSAGEThe 30-day all-cause readmission rate for Clostridiodes difficile Enterocolitis was noted to be 21.4% in 2018.Independent predictors of 30-day all-cause readmissions for Clostridiodes difficile Enterocolitis include diabetes mellitus, discharged against medical advice and chronic kidney disease.Readmissions of Clostridiodes difficile Enterocolitis had higher mortality rates, healthcare cost and length of hospital stay compared to index admissions.

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.

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.

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.

Outcomes and Predictors of 30-Day Readmissions for Hyperthyroidism: A Nationwide Study.

Hyperthyroidism is associated with an elevated risk of cardiovascular events and worse hospital outcomes. The Nationwide Readmissions Database (NRD) 2018 was used to determine the characteristics of 30-day readmission in patients with hyperthyroidism. The 30-day all-cause readmission rate for hyperthyroidism was 10.3%. About 21.7% had hyperthyroidism as the principal diagnosis on readmission. Readmissions were associated with an increased odds of inpatient mortality (odds ratio, 7.04; 95% confidence interval [CI], 3.97 to 12.49), length of stay (5.2 days vs. 4.0 days; 95% CI, 0.7 to 1.8), total hospital charges, and cost of hospitalizations. Independent predictors of 30-day all-cause readmissions included Charlson Comorbidity Index ≥3 (adjusted hazard ratio [aHR], 1.76; 95% CI, 1.15 to 2.71), discharge against medical advice (aHR, 2.30; 95% CI, 1.50 to 3.53), protein-energy malnutrition (aHR, 1.54; 95% CI, 1.15 to 2.07), and atrial fibrillation (aHR, 1.41; 95% CI, 1.11 to 1.79). Aggressive but appropriate monitoring is warranted in patients with hyperthyroidism to prevent readmissions.

Trends in hospitalizations and mortality for inflammatory bowel disease from a nationwide database study between 2008 and 2018.

This study aimed to describe the trends, inpatient outcomes, and disease burden of hospitalizations for ulcerative colitis (UC) and Crohn's disease (CD). Our study included data on hospitalizations with a principal discharge diagnosis of CD and UC gathered from the Nationwide Inpatient Sample for the years 2008, 2010, 2012, 2014, 2016, and 2018. Individuals ≤18 years and elective hospitalizations were excluded. From 2008 to 2018, we noted a rising trend for UC hospitalizations (P trend < 0.001). However, there was no statistically significant trend for CD hospitalizations (P trend = 0.249). The overall inpatient mortality for UC downtrended from 1.09% in 2008 to 0.42% in 2014 (P trend < 0.001). Additionally, inpatient mortality for CD also downtrended with a decrease from 0.28% in 2008 to 0.17% in 2016 (P trend = 0.002). Odds of inpatient mortality from 2008 to 2018 were significantly higher for UC than for CD. In conclusion, both CD and UC saw a significant decline in mortality over the study period, but UC hospitalizations had a higher odds of inpatient mortality for all study years.

Clostridium difficile Infection Hospitalizations in the United States: Insights From the 2017 National Inpatient Sample.

BACKGROUND: There is a paucity of contemporary national estimates for Clostridium difficile infection (CDI) hospitalizations by age group, sex, and region in the US population. Also, there is lack of contemporary national statistics on CDI hospitalizations with comorbidities. METHODS: We analyzed the 2017 National Inpatient Sample (NIS) to determine the population-based rates of CDI hospitalizations, characteristics of hospitalizations with CDI, and the rates of comorbidities associated with CDI hospitalizations. RESULTS: There were 329,460 CDI-related hospitalizations in 2017 (almost 1% of all hospitalizations). The average age for patients admitted with CDI as a principal or secondary diagnosis was 64.7 years (almost 20 years older when compared with all other hospitalizations). Patients 85 years and older had the highest rate of CDI hospitalizations (716 per 100,000 hospitalizations), and patients less than 18 years of age had the lowest rate (12 per 100,000 hospitalizations). There was a progressive increase in the CDI hospitalization rates with each successive age group. The hospitalization rates were higher in females (114 per 100,000 hospitalizations) than males (88 per 100,000 hospitalizations). The CDI hospitalization rate was highest in the Northeast (109 per 100,000 hospitalizations) and lowest in the West (84 per 100,000 hospitalizations). Fluid and electrolyte disturbance (63.3%) and renal failure (33.4%) were the two most common comorbidities associated with CDI hospitalizations. When CDI is a secondary diagnosis, major loss of function, extreme likelihood of dying, septicemia, and septic shock were more common in comparison to CDI as a principal diagnosis. CONCLUSIONS: CDI hospitalization rates were highest in the elderly over 85 years old and declined with successive decreases in age. Women had higher CDI hospitalization rates than men, and fluid and electrolyte disturbances and renal failure were the most common comorbid conditions. The presence of CDI as a comorbid condition at the time of hospitalization for other principal diagnoses or development of CDI during a hospitalization for other principal diagnoses significantly increases the risk of in-hospital morbidity and mortality.

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.

Rate and Predictors of 30-day Readmission Following Diabetic Ketoacidosis in Type 1 Diabetes Mellitus: A US Analysis.

CONTEXT: Diabetic ketoacidosis (DKA) is a serious endocrine emergency, associated with morbidity and mortality. Readmissions play a significant but sometimes preventable role in healthcare cost burden on the US. OBJECTIVE: This study aimed to describe rates and characteristics of nonelective 30-day readmission among adult patients with diabetes mellitus type 1 (T1DM) hospitalized for DKA and also identify predictors of readmission. METHODS: The study analyzed the 2018 Nationwide Readmission Database. DKA hospitalizations in patients with T1DM were classified using International Classification of Diseases, Tenth Revision, Clinical Modification codes. We utilized chi-squared tests to compare baseline characteristics between readmissions and index hospitalizations. Multivariable Cox regression was employed to identify independent predictors of readmission. Following this, we developed a 30-day readmission risk scoring system based on independent predictors. RESULTS: The 30-day all-cause readmission rate for DKA was 19.4%. A majority of patients (64.8%) had DKA as the principal diagnosis on readmission. Readmitted patients had a significantly higher mean age (35.3 vs 34.9 years, P = .018) and a higher proportion of females (52.8 vs 49.6%, P < .001) than the index admission. Readmission following DKA was associated with higher odds of inpatient mortality (0.69 vs 0.24%, OR 2.84, 95% CI 1.99-4.06, P < .001). Independent predictors of 30-day all-cause readmission included female sex, index hospitalizations with Charlson Comorbidity Index (CCI) score of 3 or greater, and being discharged against medical advice (AMA). CONCLUSION: The readmission rate for DKA in T1DM patients is high, and most patients have DKA as the principal diagnosis on readmission. A CCI equal to or greater than 3, hypertension, female sex, and being discharged AMA were significant predictors of readmission.

Comparing patient characteristics and outcomes in type 1 versus type 2 diabetes with diabetic ketoacidosis: a review and a propensity-matched nationwide analysis.

Diabetic ketoacidosis (DKA) is a known complication of patients with type 1 diabetes mellitus (T1DM), but less common in type 2 diabetes mellitus (T2DM). The aim of this study was to compare the outcomes of patients admitted to the hospital with DKA in T1DM versus T2DM. This was a population-based, retrospective, cohort study using data from the Nationwide Inpatient Sample. The group of patients hospitalized for DKA was divided based on a secondary diagnosis of either T1DM or T2DM. The primary outcome was inpatient mortality, and the secondary outcomes were rate of complications, length of hospital stay (LOS) and total hospital charge (THC). The inpatient mortality for DKA was 0.27% (650 patients). In T2DM, the adjusted OR (aOR) for mortality was 2.13 (95% CI 1.38 to 3.28, p=0.001) with adjusted increase in mean THC of $6035 (95% CI 4420 to 7652, p<0.001) and mean LOS of 0.5 day (95% CI 0.3 to 0.6, p<0.001) compared with T1DM. Patients with T2DM had significantly higher odds of having septic shock (aOR 2.02, 95% CI 1.160 to 3.524, p=0.013) compared with T1DM. T2DM was associated with higher inpatient mortality, septic shock and increase in healthcare utilization costs compared with T1DM.
