Postoperative Complications Following Ankle Arthrodesis in Patients With Hepatitis C: Matched Propensity Score Analysis

Background: Hepatitis C is associated with increased adverse events following surgery. The goals of this study were therefore to evaluate postoperative outcomes in patients with hepatitis C following ankle arthrodesis. Materials and Methods: A review of Medicare patients was performed to identify patients who underwent ankle arthrodesis. Patients were then divided into those with a preoperative history of hepatitis C and those who did not and were matched using propensity scores. Outcomes of interest were analyzed using multivariate logistic regression. Results: A diagnosis of hepatitis C was associated with a significantly increased risk of myocardial infarction, emergency department visits, and readmission within 90 days following surgery. In addition, hepatitis C is associated with an increased length of stay, cost of hospitalization, and total hospital charge. Conclusions: A diagnosis of hepatitis C was associated with a significant increase in hospital resource utilization during the initial inpatient stay and the immediate post-discharge period. Level of Evidence: III

Opioid use disorder among hospitalized adults in North Carolina: Comparative analysis of national and statewide trends

Objective: Hospital resource utilization is reported to be higher among patients with opioid use disorder (OUD) compared with those without OUD at national and local levels. However, utilization of healthcare services associated with OUD in North Carolina (NC) has not been adequately characterized. We describe inpatient hospital resource utilization among adults with an OUD—diagnosed in NC and the United States (US). We hypothesize that hospitalized adults with OUD will have longer hospital stays, more frequent use of emergency services, a higher number of diagnoses, and comparable hospital charges compared with hospitalized adults without OUD.Design: A retrospective cross-sectional study analyzing hospital discharge abstracts included in the 2016 NC State Inpatient Databases (SIDs) and the 2016 National Inpatient Sample (NIS). OUD and non-OUD groups were compared using the Student's t-test for continuous variables and the χ2 test for categorical variables.Participants: Adults 18 years and older from SID (n = 25,871) and NIS (n = 148,255) databases were included in the analysis.Main outcome measures: Length of stay (LOS), use of emergency services, discharge diagnosis, and hospital charge among hospitalized adults with OUD. Results: In NC, patients with OUD were younger (age 18-35), more likely to be white, and more likely to be hospitalized in areas with the lowest median income compared with patients without OUD. Compared to the US, twice as many NC OUD patients were self-payers. Hispanic patients, Medicare beneficiaries, and those in the highest income areas experienced the longest LOS and highest hospital charge. Patients with OUD were more likely to have five or more diagnoses and those with five or more diagnoses had higher LOS and hospital charges. OUD hospitalizations were also associated with more frequent use of emergency services. The most common co-occurring diagnoses were psychoses, substance abuse or dependence, and septicemia or severe sepsis.Conclusion: High percentages of self-payers and lower-income OUD patients indicate the need for Medicaid eligibility outreach programs in NC. High LOS and hospital charges among Hispanic, Medicare-covered, and high-income OUD patients call for a more detailed examination to identify underlying causes of disproportionate resource utilization in NC hospitals.

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.

Diabetes Does Not Worsen Outcomes of Patients Admitted for Hyperthyroidism: Analysis of the National Inpatient Sample

Introduction: Both diabetes mellitus (DM) and hyperthyroidism are common diseases. However, it is unclear if co-existing DM worsens outcomes in patients with hyperthyroidism. This study aims to compare the outcomes of patients primarily admitted for hyperthyroidism with and without a secondary diagnosis of DM. Methods: Data were extracted from the National Inpatient Sample (NIS) 2016 and 2017 Database. NIS is the largest inpatient hospitalization database in the United States. The NIS was searched for hospitalizations for adult patients with hyperthyroidism as principal diagnosis with and without DM as secondary diagnosis using ICD 10 codes. The primary outcome was inpatient mortality. Hospital length of stay (LOS), total hospital charges and NSTEMI were secondary outcomes of interest. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders. Results: There were over 71 million hospitalizations in the combined NIS 2016 and 2017 database. Out of 17,705 hospitalizations for hyperthyroidism, 2,160 (15.9%) had DM. Hospitalizations for hyperthyroidism with DM had similar inpatient mortality [0.35% vs 0.50%, AOR 0.25, 95% CI (0.05–1.30), P= 0.101], total hospital charge [$47,001 vs $36,978 P=0.220], LOS [4.50 vs 3.48 days, P=0.050] and NSTEMI compared to those without DM. Conclusion: Hospitalizations for hyperthyroidism with DM had similar inpatient mortality, total hospital charges, LOS and odds of undergoing ablation compared to those without obesity.

Lung involvement in systemic sclerosis is associated with adverse hospital outcomes: insights from the National Inpatient Sample

This study aimed to compare outcomes of systemic sclerosis (SSc) hospitalizations with and without lung involvement. The primary outcome was inpatient mortality while secondary outcomes were hospital length of stay (LOS) and total hospital charge. Data were abstracted from the National Inpatient Sample (NIS) 2016 and 2017 database. This database is the largest collection of inpatient hospitalization data in the USA. The NIS was searched for SSc hospitalizations with and without lung involvement as principal or secondary diagnosis using International Classification of Diseases 10th Revision (ICD-10) codes. SSc hospitalizations for patients aged ≥18 years from the above groups were identified. Multivariate logistic and linear regression analysis was used to adjust for possible confounders for the primary and secondary outcomes, respectively. There were over 71 million discharges included in the combined 2016 and 2017 NIS database. 62,930 hospitalizations were for adult patients who had either a principal or secondary ICD-10 code for SSc. 5095 (8.10%) of these hospitalizations had lung involvement. Lung involvement group had greater inpatient mortality (9.04% vs 4.36%, adjusted OR 2.09, 95% CI 1.61 to 2.73, p<0.0001), increase in mean adjusted LOS of 1.81 days (95% CI 0.98 to 2.64, p<0.0001), and increase in mean adjusted total hospital charge of $31,807 (95% CI 14,779 to 48,834, p<0.0001), compared with those without lung involvement. Hospitalizations for SSc with lung involvement have increased inpatient mortality, LOS and total hospital charge compared with those without lung involvement. Collaboration between the pulmonologist and the rheumatologist is important in optimizing outcomes of SSc hospitalizations with lung involvement.

Kidney-Pancreas Transplant Recipients Experience Higher Risk of Complications Compared to the General Population after Undergoing Coronary Artery Bypass Grafting

This retrospective analysis aims to identify differences in surgical outcomes between pancreas and/or kidney transplant recipients compared with the general population undergoing coronary artery bypass grafting (CABG). Using Nationwide Inpatient Sample (NIS) data from 2005 to 2014, patients who underwent CABG were stratified by either no history of transplant, or history of pancreas and/or kidney transplant. Multivariate analysis was used to calculate odds ratio (OR) to evaluate in-hospital mortality, morbidity, length of stay (LOS), and total hospital charge in all centers. The analysis was performed for both nonemergency and emergency CABG. Overall, 2,678 KTx (kidney transplant alone), 184 PTx (pancreas transplant alone), 254 KPTx (kidney-pancreas transplant recipients), and 1,796,186 Non-Tx (nontransplant) met inclusion criteria. KPTx experienced higher complication rates compared with Non-Tx (78.3 vs. 47.8%, p < 0.01). Those with PTx incurred greater total hospital charge and LOS. On weighted multivariate analysis, KPTx was associated with an increased risk for developing any complication following CABG (OR 3.512, p < 0.01) and emergency CABG (3.707, p < 0.01). This risk was even higher at transplant centers (CABG OR 4.302, p < 0.01; emergency CABG OR 10.072, p < 0.001). KTx was associated with increased in-hospital mortality following emergency CABG, while PTx and KPTx had no mortality to analyze. KPTx experienced a significantly higher risk of complications compared with the general population after undergoing CABG, in both transplant and nontransplant centers. These outcomes should be considered when providing perioperative care.

Abstract 16225: Protein Energy Malnutrition is Associated With Increased Inpatient Mortality in Patients Admitted for Atrial Fibrillation: Analysis of the National Inpatient Sample

Introduction: Various forms of protein energy malnutrition (PEM) has been shown to affect different heart pathologies through its underlying pathogenesis of unabating chronic inflammation. The effect of PEM on atrial fibrillation (AF) is unclear. Our study sought to estimate the impact of PEM on clinical outcomes of hospitalizations for AF using a national database Methods: We queried the National Inpatient Sample (NIS) 2016 and 2017 database. The NIS is the largest inpatient hospitalization database in the United States. The NIS was searched for hospitalization of adult patients with AF as a principal diagnosis with and without PEM as a secondary diagnosis using ICD-10 codes. The primary outcome was inpatient mortality while the secondary outcomes were hospital length of stay (LOS) and total hospital charge. STATA software was used for analysis. Multivariate logistic and linear regression analysis was used accordingly to adjust for confounders. Results: There were over 71 million discharges in the combined 2016 and 2017 NIS database. Out of 821,629 AF hospitalizations, 3% had PEM. Hospitalization for AF with PEM had a statistically significant increase in mortality (5.2% vs 0.8%, AOR 2.33, 95% CI 1.96 - 2.78, P<0.0001), with an adjusted increase in mean hospital charge of $15,862 (95% CI 11,999 - 19,725, P<0.0001) and a 2 day increase in LOS (95% CI 2.00 - 2.50, P= <0.0001) compared to those without PEM. Conclusion: In conclusion, PEM resulted in increased mortality, LOS and total hospital charge in patients hospitalized with AF. Nutritional rehabilitation in patients with PEM and concomittant AF may be needed to improve outcomes.
