Abstract
As a prospective payment method, diagnosis-related groups (DRGs)'s implementation has varying effects on different regions and adopt different case classification systems. Our goal is to build a structured public online knowledgebase describing the worldwide practice of DRGs, which includes systematic indicators for DRGs' performance assessment. Therefore, we manually collected the qualified literature from PUBMED and constructed DRGKB website. We divided the evaluation indicators into four categories, including (i) medical service quality; (ii) medical service efficiency; (iii) profitability and sustainability; (iv) case grouping ability. Then we carried out descriptive analysis and comprehensive scoring on outcome measurements performance, improvement strategy and specialty performance. At last, the DRGKB finally contains 297 entries. It was found that DRGs generally have a considerable impact on hospital operations, including average length of stay, medical quality and use of medical resources. At the same time, the current DRGs also have many deficiencies, including insufficient reimbursement rates and the ability to classify complex cases. We analyzed these underperforming parts by domain. In conclusion, this research innovatively constructed a knowledgebase to quantify the practice effects of DRGs, analyzed and visualized the development trends and area performance from a comprehensive perspective. This study provides a data-driven research paradigm for following DRGs-related work along with a proposed DRGs evolution model.

Abstract
Background With the advent of novel treatments, there is a declining trend in the multiple myeloma (MM) mortality rate with an increasing hospitalization rate. However, there is limited population-based data on trends and outcomes of hospitalizations due to MM in the United States (US). Methods We analyzed the publicly available Nationwide Inpatient Sample (NIS) from 2007 to 2017 to identify MM hospitalizations. Results Hospitalizations for MM increased from 17,100 (8.71%) in 2007 to 19,490 (9.92%) in 2017. The in-hospital mortality rate declined from 8.4% in 2007 to 4.9% in 2017 (P <0.001) and discharge to facilities decreased from 20.4% in 2007 to 17.4% in 2017 (P <0.001). The odds of in-hospital mortality were higher with increasing age (odds ratio (OR): 1.46; 95% confidence interval (CI): 1.38 -1.54; P <0.0001), pneumonia (OR: 4.18; 95% CI: 3.63 - 4.81, P <0.0001), septicemia (OR: 2.50; 95% CI: 2.22 - 2.82; P <0.0001), renal failure (OR: 1.48; 95% CI: 1.34 -1.64; P <0.0001), uninsured/self-pay insurance status (OR: 2.69; 95% CI: 2.18 - 3.3; P <0.0001), rural hospital (OR: 2.26; 95% CI: 1.88 -2.72; P<0.0001), and urban-non-teaching hospitals (OR: 1.38; 95% CI: 1.23 - 1.56; P <0.0001). Also, increasing age (OR: 1.14; 95% CI: 1.11-1.18, P <0.0001), Black race (OR: 1.12; 95% CI: 1.02-1.23, P <0.0001), and multiple comorbidities were associated with higher disability. Conclusion Hospitalizations for MM continued to increase, whereas in-hospital mortality continued to decrease. Advanced age, sepsis, pneumonia, and renal failure were associated with higher odds of mortality in MM patients.

Abstract
Aim of the study Biliary complications are the leading causes of morbidity and mortality after liver transplant (LT). However, national data on endoscopic retrograde cholangiopancreatography (ERCP) usage and outcomes in LT patients are lacking. Our study aims to identify the trends, outcomes, and predictors of ERCP and related complications in this patient subgroup. Material and methods We derived our study cohort from the Nationwide Inpatient Sample (NIS) of the Healthcare Cost and Utilization Project (HCUP) between 2007 and 2017. LT patients were identified using ICD-9/10CM diagnosis codes and patients who underwent ERCP were identified by ICD-9/10-CM procedure codes. We utilized the Cochrane-Armitage trend test and multivariate logistic regression to analyze temporal trends, outcomes, and predictors. Results A total of 372,814 hospitalizations occurred in LT patients between 2007 and 2017. ERCP was performed in 2.05% (n = 7632) of all hospitalizations. There was a rise in ERCP procedures from 1.96% (n = 477) in 2007 to 2.05% (n = 845) in 2017. Among LT patients who underwent ERCP, the in-hospital mortality rate was 1% (n = 73) and 8% (n = 607) were discharged to facilities. Mean length of hospital stay was 7 ±0.3 days. Septicemia was the most common periprocedural complication (18.3%, n = 1399) followed by post-ERCP pancreatitis (8.8%, n = 674). Conclusions There has been an increase in ERCP procedures over the past decade among LT patients. Our study highlights the periprocedural complications and outcomes of ERCP in LT patients from a nationally representative dataset.

Abstract
BACKGROUND Older adults (OAs; ≥ 65 years) comprise a growing population in the United States and are anticipated to require an increasing number of emergency general surgery procedures (EGSPs). The aims of this study were to identify the frequency of EGSPs and compare cost of care in OAs managed at teaching hospitals (THs) vs nonteaching hospitals (NTHs). METHODS A retrospective review of data from the Maryland Health Services Cost Review Commission database from 2009 to 2018 for OAs undergoing EGSPs was undertaken. Data collected included demographics, all patient-refined (APR)-severity of illness (SOI), APR-risk of mortality (ROM), Charlson Comorbidity Index (CCI), EGSPs (partial colectomy (PC), small bowel resection, cholecystectomy, operative management of peptic ulcers, lysis of adhesions, appendectomy, and laparotomy, categorized hospital charges, length of stay (LOS), and mortality. RESULTS Of the 55,401 OAs undergoing EGSPs in this study, 28,575 (51.6%) were treated at THs and 26,826 (48.4%) at NTHs. OAs at THs presented with greater APR-ROM (major 25.6% vs 24.9%, extreme 22.6% vs 22.0%, P=.01), and CCI (3.1±3 vs 2.7±2.8, P<.001) compared to NTHs. Lysis of adhesions, cholecystectomy, and PC comprised the overall most common EGSPs. Older adults at THs incurred comparatively higher median hospital charges for every EGSP due to increased room charges and LOS. Mortality was higher at THs (6.13% vs 5.33%, P<.001). CONCLUSION While acuity of illness appears similar, cost of undergoing EGSPs for OAs is higher in THs vs NTHs due to increased LOS. Future work is warranted to determine and mitigate factors that increase LOS at THs.

Abstract
Background: Ventilator-associated pneumonia (VAP) is a hospital-acquired pneumonia that occurs more than 48 hours after mechanical ventilation. Studies showing temporal trends, predictors, and outcomes of VAP are very limited. Objective: We used the National database to delineate the trends and predictors of VAP from 2009 to 2017. Methods: We analyzed data from the Nationwide Inpatient Sample (NIS) for adult hospitalizations who received mechanical ventilation (MV) by using ICD-9/10-CM procedures codes. We excluded hospitalizations with length of stay (LOS) less than two days. VAP and other diagnoses of interest were identified by ICD-9/10-CM diagnosis codes. We then utilized the Cochran Armitage trend test and multivariate survey logistic regression models to analyze the data. Results: Out of a total of 5,155,068 hospitalizations who received mechanical ventilation, 93,432 (1.81%) developed VAP. Incidence of VAP decreased from 20/1000 in 2008 to 17/1000 in 2017 with a 5% decrease. Patients who developed VAP had lower mean age (59 vs 61; p<0.001) and higher LOS (25 days vs. 12 days; p<0.001). In multivariable regression analysis, we identified that males, African Americans, teaching hospitals and co-morbidities like neurological disorders, pulmonary circulation disorders and electrolyte disorders are associated with the increased odds of developing VAP. VAP was also associated with higher rates of discharge to facilities and increased LOS. Conclusion: Our study identified the trends along with the risk predictors of VAP in MV patients. Our goal is to lay the foundation for further in-depth analysis of this trend for better risk stratification and development of preventive strategies to reduce the incidence of VAP among MV patients.

Abstract
BACKGROUND AND OBJECTIVES Pulmonary hypertension (PH) leads to significant morbidity and mortality in pediatric patients and increases the readmission rates for hospitalizations. This study evaluates the risk factors and comorbidities associated with an increase in 30-day readmissions among pediatric PH patients. METHODS National Readmission Database (NRD) 2017 was searched for patients less than 18 years of age who were diagnosed with PH based on the International Classification of Diseases, 10th Revision (ICD-10). Statistical Package for the Social Sciences (SPSS) software v25.0 (IBM Corp., Armonk, NY) was used for statistical analysis. RESULTS Of 5.52 million pediatric encounters, 10,501 patients met the selection criteria. The 30-day readmission rate of 14.43% (p < 0.001) was higher than hospitalizations from other causes {Odds Ratio (OR) 4.02 (3.84-4.20), p < 0.001}. The comorbidities of sepsis {OR 0.75 (0.64-0.89), p < 0.02} and respiratory infections {OR 0.75 (0.67-0.85), p < 0.001} were observed to be associated with lower 30-day readmissions. Patients who required invasive mechanical ventilation via endotracheal tube {OR 1.66 (1.4-1.96), p < 0.001} or tracheostomy tube {OR 1.35 (1.15-1.6), p < 0.001} had increased unplanned readmissions. Patients with higher severity of illness based on All Patients Refined Diagnosis Related Groups (APR-DRG) were more likely to get readmitted {OR 7.66 (3.13-18.76), p < 0.001}. CONCLUSION PH was associated with increased readmission rates compared to the other pediatric diagnoses, but the readmission rate in this study was lower than one previous pediatric study. Invasive mechanical ventilation, Medicaid insurance, higher severity of illness, and female gender were associated with a higher likelihood of readmission within 30 days.

Abstract
Background Hepatocellular Carcinoma (HCC) is a severe complication of cirrhosis and the incidence of HCC has been increasing in the United States (US). We aim to describe the trends, characteristics, and outcomes of hospitalizations due to HCC across the last decade. Methods We derived a study cohort from the Nationwide Inpatient Sample (NIS) for the years 2008-2017. Adult hospitalizations due to HCC were identified using the International Classification of Diseases (9th/10th Editions) Clinical Modification diagnosis codes (ICD-9-CM/ICD-10-CM). Comorbidities were also identified by ICD-9/10-CM codes and Elixhauser Comorbidity Software (Agency for Healthcare Research and Quality, Rockville, Maryland, US). Our primary outcomes were in-hospital mortality and discharge to the facility. We then utilized the Cochran-Armitage trend test and multivariable survey logistic regression models to analyze the trends, outcomes, and predictors. Results A total of 155,436 adult hospitalizations occurred due to HCC from 2008-2017. The number of hospitalizations with HCC decreased from 16,754 in 2008 to 14,715 in 2017. Additionally, trends of in-hospital mortality declined over the study period but discharge to facilities remained stable. Furthermore, in multivariable regression analysis, predictors of increased mortality in HCC patients were advanced age (OR 1.1; 95%CI 1.0-1.2; p< 0.0001), African American (OR 1.3; 95%CI 1.1-1.4;p< 0.001), Rural/ non-teaching hospitals (OR 2.7; 95%CI 2.4-3.3; p< 0.001), uninsured (OR 1.9; CI 1.6-2.2; p< 0.0001) and complications like septicemia and pneumonia as well as comorbidities such as hypertension, diabetes mellitus, and renal failure. We observed similar trends in discharge to facilities. Conclusions In this nationally representative study, we observed a decrease in hospitalizations of patients with HCC along with in-hospital mortality; however, discharge to facilities remained stable over the last decade. We also identified multiple predictors significantly associated with increased mortality, some of which are potentially modifiable and can be points of interest for future studies.

Abstract
PURPOSE To evaluate the prevalence of incontinence and treatment of incontinence-associated dermatitis (IAD) and associations with outcomes including total cost of care, length of stay (LOS), 30-day readmission, sacral area pressure injuries present on admission and hospital acquired pressure injuries, and progression of all sacral area pressure injuries to a higher stage. DESIGN Retrospective analysis. SUBJECTS AND SETTINGS Data were retrieved from the Premier Healthcare Database and comprised more than 15 million unique adult patient admissions from 937 hospitals. Patients were 18 years or older and admitted to a participating hospital between January 1, 2016, and December 31, 2019. METHODS Given the absence of an IAD International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code, we categorized patients treated for IAD by selecting patients with a documented incontinence ICD-10-CM code and a documented charge for dermatology products used to treat IAD. The t test and χ2 tests determined whether incontinence and treatment for IAD were associated with outcomes. RESULTS Incontinence prevalence was 1.5% for the entire sample; prevalence rate for IAD among incontinent patients was 0.7%. As compared to continent patients, incontinent patients had longer LOS (6.4 days versus 4.4 days), were 1.4 times more likely to be readmitted, 4.7 times more likely to have a sacral pressure injury upon admission pressure injury, 5.1 times more likely to have a sacral hospital-acquired pressure injury, and 5.8 times more likely to have a sacral pressure injury progress to a severe stage. As compared to incontinent patients without IAD treatment, those with IAD treatment had longer LOS (9.7 days versus 6.4 days), were 1.3 times more likely to be readmitted, and were 2.0 times more likely to have a sacral hospital-acquired pressure injury. Total index hospital costs were 1.2 times higher for incontinent patients and 1.3 times higher for patients with IAD treatment. CONCLUSIONS Incontinence and IAD prevalence are substantially lower than past research due to underreporting of incontinence. The lack of an ICD-10-CM code for IAD further exacerbates the underreporting of IAD. Despite low prevalence numbers, our results show higher health care costs and worse outcomes for incontinent patients and patients with IAD treatment.

Utilization Trends and Predictors of Non-invasive and Invasive Ventilation During Hospitalization Due to Community-Acquired Pneumonia. Cureus 2021; 13:e17954. [PMID: 34660142 PMCID: PMC8515501 DOI: 10.7759/cureus.17954] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/14/2021] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Community-acquired pneumonia (CAP) is associated with significant morbidity and mortality. Non-invasive ventilation (NIV) and invasive mechanical ventilation (IMV) are most important interventions for patients with severe CAP associated with respiratory failure. We analysed utilization trends and predictors of non-invasive and invasive ventilation in patients hospitalized with CAP. METHODS Nationwide Inpatient Sample and Healthcare Cost and Utilization Project data for years 2008-2017 were analysed. Adult hospitalizations due to CAP were identified by previously validated International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) and International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) codes. We then utilized the Cochran-Armitage trend test and multivariate survey logistic regression models to analyse temporal incidence trends, predictors, and outcomes. We used SAS 9.4 software (SAS Institute Inc., Cary, NC, USA) for analysing data. RESULTS Out of a total of 8,385,861 hospitalizations due to CAP, ventilation assistance was required in 552,395 (6.6%). The overall ventilation use increased slightly; however, IMV utilization decreased, while NIV utilization increased. In multivariable regression analysis, males, Asian/others and weekend admissions were associated with higher odds of any ventilation utilization. Concurrent diagnoses of septicemia, congestive heart failure, alcoholism, chronic lung diseases, pulmonary circulatory diseases, diabetes mellitus, obesity and cancer were associated with increased odds of requiring ventilation assistance. Ventilation requirement was associated with high odds of in-hospital mortality and discharge to facility. CONCLUSION The use of NIV among CAP patients has increased while IMV use has decreased over the years. We observed numerous factors linked with a higher use of ventilation support. The requirement of ventilation support is also associated with very high chances of mortality and morbidity.

Abstract
Objectives To compare in-hospital mortality between intracerebral hemorrhage (ICH) patients in rural hospitals to those in urban hospitals of the USA. Methods We used the National Inpatient Sample to retrospectively identify all cases of ICH in the USA over the period 2004–2014. We used multivariable-adjusted models to compare odds of mortality between rural and urban hospitals. Joinpoint regression was used to evaluate trends in age- and sex-adjusted mortality in rural and urban hospitals over time. Results From 2004 to 2014, 5.8% of ICH patients were admitted in rural hospitals. Rural patients were older (mean [SE] 76.0 [0.44] years vs. 68.8 [0.11] years in urban), more likely to be white and have Medicare insurance. Age- and sex-adjusted mortality was greater in rural hospitals (32.2%) compared to urban patients (26.5%) (p value < 0.001). After multivariable adjustment, patients hospitalized in rural hospitals had two times the odds of in-hospital death compared to patients in urban hospitals (OR 2.07, 95% CI 1.77–2.41. p value < 0.001). After joinpoint regression, mortality declined in urban hospitals by an average of 2.8% per year (average annual percentage change, [AAPC] − 2.8%, 95% CI − 3.7 to − 1.8%), but rates in rural hospitals remained unchanged (AAPC − 0.54%, 95% CI − 1.66 to 0.58%). Conclusions Despite current efforts to reduce disparity in stroke care, ICH patients hospitalized in rural hospitals had two times the odds of dying compared to those in urban hospitals. In addition, the ICH mortality gap between rural and urban centers is increasing. Further studies are needed to identify and reverse the causes of this disparity.

Abstract
Introduction Approximately 5-10% of strokes occur in adults of less than 45 years of age. The rising prevalence of stroke risk factors may increase stroke rates in young adults (YA). We aimed to compare risk factors and outcomes of acute ischemic stroke (AIS) among YA. Methods Adult hospitalizations for AIS and concurrent risk factors were found in the Nationwide Inpatient Sample database. Weighted analysis using chi-square and multivariable survey logistic regression was performed to evaluate AIS-related outcomes and risk factors among YA (18-45 years) and older patients. Results A total of 4,224,924 AIS hospitalizations were identified from 2003 to 2014, out of which 198,378 (4.7%) were YA. Prevalence trend of YA with AIS showed incremental pattern over time (2003: 4.36% to 2014: 4.7%; pTrend<0.0001). In regression analysis, the risk factors associated with AIS in YA were obesity (adjusted odds ratio {aOR}: 2.26; p<0.0001), drug abuse (aOR: 2.56; p<0.0001), history of smoking (aOR: 1.20; p<0.0001), infective endocarditis (aOR: 2.08; p<0.0001), cardiomyopathy (aOR: 2.11; p<0.0001), rheumatic fever (aOR: 4.27; p=0.0014), atrial septal disease (aOR: 2.46; p<0.0001), ventricular septal disease (aOR: 4.99; p<0.0001), HIV infection (aOR: 4.36; p<0.0001), brain tumors (aOR: 7.89; p<0.0001), epilepsy (aOR: 1.43; p<0.0001), end stage renal disease (aOR: 2.19; p<0.0001), systemic lupus erythematous (aOR: 3.76; p<0.0001), polymyositis (aOR: 2.72; p=0.0105), ankylosis spondylosis (aOR: 2.42; p=0.0082), hypercoagulable state (aOR: 4.03; p<0.0001), polyarteritis nodosa (aOR: 5.65; p=0.0004), and fibromuscular dysplasia (aOR: 2.83; p<0.0001). Conclusion There is an increasing trend in AIS prevalence over time among YA. Both traditional and non-traditional risk factors suggest that greater awareness is needed, with prevention strategies for AIS among young adults.

Abstract
BACKGROUND Though weight is a major consideration when transfusing blood in pediatric patients, it is generally not considered when dosing transfusions in adults. We hypothesized that the change in hemoglobin (Hb) concentration is inversely proportional to body weight when transfusing red blood cells (RBC) in adults. METHODS A total of 13,620 adult surgical patients at our institution were assessed in this retrospective cohort study (2009-2016). Patients were stratified based on total body weight (kg): 40-59.9 (16.6%), 60-79.9 (40.4%), 80-99.9 (28.8%), 100-119.9 (11.3%), and 120-139.9 (2.9%). The primary outcome was the change in Hb per RBC unit transfused. Subgroup analyses were performed after stratification by sex (male/female) and the total number of RBC units received (1/2/≥3 units). Multivariable models were used to assess the association between weight and change in Hb. RESULTS As patients' body weight increased, there was a decrease in the mean change in Hb per RBC unit transfused (40-59.9 kg: 0.85 g/dL, 60-79.9 kg: 0.73 g/dL, 80-99.9 kg: 0.66 g/dL, 100-119.9 kg: 0.60 g/dL, 120-139.9 kg: 0.55 g/dL; p < .0001). This corresponded with a 35% difference in the change in Hb between the lowest and highest weight categories on univariate analysis. Similar trends were seen after subgroup stratification. On multivariable analysis, for every 20 kg increase in patient weight, there was a ~6.5% decrease in the change in Hb per RBC unit transfused (p < .0001). CONCLUSIONS Patient body weight differentially impacts the change in Hb after RBC transfusion. These findings justify incorporating body weight into the clinical decision-making process when transfusing blood in adult surgical patients.

Abstract
BACKGROUND Early palliative care consultation ("PCC") to discuss goals-of-care benefits seriously ill patients. Risk factor profiles associated with the timing of conversations in hospitals, where late conversations most likely occur, are needed. OBJECTIVE To identify risk factor patient profiles associated with PCC timing before death. METHODS Secondary analysis of an observational study was conducted at an urban, academic medical center. Patients aged 18 years and older admitted to the medical center, who had PCC, and died July 1, 2014 to October 31, 2016, were included. Patients admitted for childbirth or rehabilitationand patients whose date of death was unknown were excluded. Classification and Regression Tree modeling was employed using demographic and clinical variables. RESULTS Of 1141 patients, 54% had PCC "close to death" (0-14 days before death); 26% had PCC 15 to 60 days before death; 21% had PCC >60 days before death (median 13 days before death). Variables associated with receiving PCC close to death included being Hispanic or "Other" race/ethnicity intensive care patients with extreme illness severity (85%), with age <46 or >75 increasing this probability (98%). Intensive care patients with extreme illness severity were also likely to receive PCC close to death (64%) as were 50% of intensive care patients with less than extreme illness severity. CONCLUSIONS A majority of patients received PCC close to death. A complex set of variable interactions were associated with PCC timing. A systematic process for engaging patients with PCC earlier in the care continuum, and in intensive care regardless of illness severity, is needed.

Abstract
CONTEXT African Americans are less likely to receive hospice care and more likely to receive aggressive end-of-life care than whites. Little is known about how palliative care consultation (PCC) to discuss goals of care is associated with hospice enrollment by race. OBJECTIVES To compare enrollment in hospice at discharge between propensity-matched cohorts of African Americans with and without PCC and whites with and without PCC. METHODS Secondary analysis of a retrospective cohort study at a high-acuity hospital; using stratified propensity-score matching for 35,154 African Americans and whites aged 18+ admitted for conditions other than childbirth or rehabilitation, who were not hospitalized at end of study, and did not die during index hospitalization (hospitalization during which first PCC occurred). RESULTS Compared with African Americans without PCC, African Americans with PCC were 15 times more likely to be discharged to hospice from index hospitalization (2.4% vs. 36.5%; P < 0.0001). Compared with white patients without PCC, white patients with PCC were 14 times more likely to be discharged to hospice from index hospitalization (3.0% vs. 42.7%; P < 0.0001). CONCLUSION In propensity-matched cohorts of seriously ill patients, PCC to discuss goals of care was associated with significant increases in hospice enrollment at discharge among both African Americans and whites. Research is needed to understand how PCC influences decision making by race, how PCC is associated with postdischarge hospice outcomes such as disenrollment and hospice lengths of stay, and if PCC is associated with improving racial disparities in end-of-life care.

Abstract
Background: African Americans receive more aggressive end-of-life care than Whites. Little is known about how palliative care consultation to discuss goals-of-care ("PCC") is associated with acute care utilization and costs by race. Objective: To compare future acute care costs and utilization between propensity-matched cohorts of African Americans with and without PCC, and Whites with and without PCC. Design: Secondary analysis of a retrospective cohort study. Setting/Subjects: Thirty-five thousand one hundred and fifty-four African Americans and Whites age 18+ admitted for conditions other than childbirth or rehabilitation, who were not hospitalized at the end of the study, and did not die during index hospitalization (hospitalization during which the first PCC occurred). Measurements: Accumulated mean acute care costs and utilization (30-day readmissions, future hospital days, future intensive care unit [ICU] admission, future number of ICU days) after discharge from index hospitalization. Results: No significant difference between African Americans with or without PCC in mean future acute care costs ($11,651 vs. $15,050, p = 0.09), 30-day readmissions (p = 0.58), future hospital days (p = 0.34), future ICU admission (p = 0.25), or future ICU days (p = 0.30). There were significant differences between Whites with PCC and those without PCC in mean future acute care costs ($8,095 vs. $16,799, p < 0.001), 30-day readmissions (10.2% vs. 16.7%, p < 0.0001), and future days hospitalized (3.7 vs. 6.3 days, p < 0.0001). Conclusions: PCC decreases future acute care costs and utilization in Whites and, directionally but not significantly, in African Americans. Research is needed to explain why utilization and cost disparities persist among African Americans despite PCC.

Abstract
Background and Purpose Rates of depression after ischemic stroke (IS) and myocardial infarction (MI) are significantly higher than in the general population and associated with morbidity and mortality. There is a lack of nationally representative data comparing depression and suicide attempt (SA) after these distinct ischemic vascular events. Methods The 2013 Nationwide Readmissions Database contains >14 million US admissions for all payers and the uninsured. Using International Classification of Disease, 9th Revision, Clinical Modification Codes, we identified index admission with IS (n = 434,495) or MI (n = 539,550) and readmission for depression or SA. We calculated weighted frequencies of readmission. We performed adjusted Cox regression to calculate hazard ratio (HR) for readmission for depression and SA up to 1 year following IS versus MI. Analyses were stratified by discharge home versus elsewhere. Results Weighted depression readmission rates were higher at 30, 60, and 90 days in patients with IS versus MI (0.04%, 0.09%, 0.12% vs. 0.03%, 0.05%, 0.07%, respectively). There was no significant difference in SA readmissions between groups. The adjusted HR for readmission due to depression was 1.49 for IS versus MI (95% CI 1.25–1.79, p < 0.0001). History of depression (HR 3.70 [3.07–4.46]), alcoholism (2.04 [1.34–3.09]), and smoking (1.38 [1.15–1.64]) were associated with increased risk of depression readmission. Age >70 years (0.46 [0.37–0.56]) and discharge home (0.69 [0.57–0.83]) were associated with reduced hazards of readmission due to depression. Conclusions IS was associated with greater hazard of readmission due to depression compared to MI. Patients with a history of depression, smoking, and alcoholism were more likely to be readmitted with depression, while advanced age and discharge home were protective. It is unclear to what extent differences in type of ischemic tissue damage and disability contribute, and further investigation is warranted.

Abstract
Introduction The opioid epidemic has been linked to several other health problems, but its impact on headache disorders has not been well studied. We performed a population-based study looking at the prevalence of opioid use in headache disorders and its impact on outcomes compared to non-abusers with headaches. Methodology We performed a cross-sectional analysis of the Nationwide Inpatient Sample (years 2008-2014) in adults hospitalized for primary headache disorders (migraine, tension-type headache [TTH], and cluster headache [CH]) using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes. We performed weighted analyses using the chi-square test, Student's t-test, and Cochran-Armitage trend test. Multivariate survey logistic regression analysis with weighted algorithm modelling was performed to evaluate morbidity, disability, and discharge disposition. Among US hospitalizations during 2013-2014, regression analysis was performed to evaluate the odds of having opioid abuse among headache disorders. Results A total of 5,627,936 headache hospitalizations were present between 2008 and 2014 of which 3,098,542 (55.06%), 113,332 (2.01%), 26,572 (0.47%) were related to migraine, TTH, and CH, respectively. Of these headache hospitalizations, 128,383 (2.28%) patients had abused opioids. There was a significant increase in the prevalence trend of opioid abuse among patients with headache disorders from 2008 to 2014. The prevalence of migraine (63.54% vs. 54.86%), TTH (2.29% vs. 2.01%), and CH (0.59% vs. 0.47%) was also higher among opioid abusers than non-abusers (p<0.0001). Opioid abusers with headaches were more likely to be younger (43 years old vs. 50 years old), men (30.17% vs. 24.78%), white (80.83% vs. 73.29%), Medicaid recipients (30.15% vs. 17.03%), and emergency admissions (85.4% vs. 78.51%) as compared to opioid non-abusers with headaches (p<0.0001). Opioid abusers with headaches had higher prevalence and odds of morbidity (4.06% vs. 3.70%; adjusted odds ratio [aOR]: 1.48; 95% CI: 1.39-1.59), severe disability (28.14% vs. 22.43%; aOR: 1.58; 95% CI: 1.53-1.63), and discharge to non-home location (17.13% vs. 18.41%; aOR: 1.35; 95% CI: 1.30-1.40) as compared to non-abusers. US hospitalizations in years 2013-2014 showed the migraine (OR: 1.61; 95% CI: 1.57-1.66), TTH (OR: 1.43; 95% CI: 1.22-1.66), and CH (OR: 1.34; 95% CI: 1.01-1.78) were linked with opioid abuse. Conclusion Through this study, we found that the prevalence of migraine, TTH, and CH was higher in opioid abusers than non-abusers. Opioid abusers with primary headache disorders had higher odds of morbidity, severe disability, and discharge to non-home location as compared to non-abusers.

Abstract
PURPOSE Early recognition and prompt prehospital care is a cornerstone of acute stroke treatment. Residents of rural areas have worse access to stroke services than urban residents. The purpose of this study was to (1) describe US trends in rural-urban stroke mortality and (2) identify possible factors associated with rural-urban stroke case-fatality disparities. METHODS This study was a nationwide retrospective cohort study of stroke admissions. The primary exposure was rurality of patient's residence. The primary outcome was death during hospital encounter. The secondary outcome was discharge to a care facility or home healthcare. Univariable and multivariable logistic regressions estimated the odds of mortality by subject rurality among stroke subjects. FINDINGS Rural stroke subjects had higher mortality than nonrural counterparts (18.6% rural vs 16.9% nonrural). After adjustment for patient and hospital factors, patient rurality was associated with increased odds of mortality (aOR = 1.11; 95% CI: 1.06-1.15; P < .001). For the secondary outcome of discharge to home, rural stroke subjects were less likely to be discharged to a care facility than nonrural stroke visits (aOR 0.94; 95% CI: 0.91-0.97; P < .001). Results were similar after adjusting for thrombolytics administration and transfer status. CONCLUSIONS Rural stroke patients have higher mortality than their urban counterparts likely due to their increased burden of chronic disease, lower health literacy, and reduced access to prompt prehospital care. There may be an opportunity for emergency medical services systems to assist in increasing stroke awareness for both patients and clinicians and to establish response patterns to expedite emergency care.

Diverting loop ileostomy versus total abdominal colectomy for clostridioides difficile colitis: outcomes beyond the index admission. Surg Endosc 2020; 35:3147-3153. [PMID: 32601762 DOI: 10.1007/s00464-020-07755-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2020] [Accepted: 06/22/2020] [Indexed: 12/01/2022]
Abstract
INTRODUCTION Diverting loop ileostomy (DLI) and colonic lavage has emerged as a valid alternative to total abdominal colectomy (TAC) for the surgical management of Clostridioides difficile colitis (CDC). However, little data are available on outcomes beyond the index admission. The objective of this study was to compare post-discharge outcomes between patients who underwent DLI and TAC for CDC. METHODS Adult patients who underwent DLI or TAC for CDC between 2011 and 2016 were identified from the Nationwide Readmissions Database, and only discharges between January and September in each calendar year were included to allow for a 90-day follow-up period for all cases. Ninety-day overall in-hospital mortality (index admission mortality plus 90-day post-discharge mortality) and 90-day unplanned readmissions were compared. To assess 6-month ileostomy reversal rates, the cohort was then truncated to exclude discharges after June in each calendar year. Multivariate regression was used to adjust for patient demographics and disease severity. RESULTS In total, 2070 patients were discharged between January and September of each included year: 1486 (71.8%) TAC compared to 584 (28.2%) DLI. Overall in-hospital mortality was higher among patients who underwent TAC (34.5% vs. 27.7%, p = 0.004); however, this association did not remain on multivariate regression (OR 1.14, 95% CI 0.91-1.43). Among the 1434 patients who were discharged alive, the 90-day unplanned readmission rate was similar in both groups (TAC: 26.1% vs. DLI: 23.1%, p = 0.26). After truncating the cohort to those patients discharged alive between January and June of each included year (n = 1016), patients who underwent DLI had a significantly greater 6-month ileostomy reversal rate (26.4% vs. 8.3%, p < 0.001). DLI was independently associated with higher odds of 6-month ileostomy reversal (OR 2.68, 95% CI 1.80-4.00). CONCLUSIONS In the surgical management of CDC, DLI is associated with equivalent mortality and unplanned readmission, but greater likelihood of 6-month ileostomy reversal, compared to TAC.

Abstract
Early prediction of in-hospital mortality can improve patient outcome. Current prediction models for in-hospital mortality focus mainly on specific pathologies. Structured pathology data is hospital-wide readily available and is primarily used for e.g. financing purposes. We aim to build a predictive model at admission using the International Classification of Diseases (ICD) codes as predictors and investigate the effect of the self-evident DNR (“Do Not Resuscitate”) diagnosis codes and palliative care codes. We compare the models using ICD-10-CM codes with Risk of Mortality (RoM) and Charlson Comorbidity Index (CCI) as predictors using the Random Forests modeling approach. We use the Present on Admission flag to distinguish which diagnoses are present on admission. The study is performed in a single center (Ghent University Hospital) with the inclusion of 36 368 patients, all discharged in 2017. Our model at admission using ICD-10-CM codes (AUCROC = 0.9477) outperforms the model using RoM (AUCROC = 0.8797 and CCI (AUCROC = 0.7435). We confirmed that DNR and palliative care codes have a strong impact on the model resulting in a decrease of 7% for the ICD model (AUCROC = 0.8791) at admission. We therefore conclude that a model with a sufficient predictive performance can be derived from structured pathology data, and if real-time available, can serve as a prerequisite to develop a practical clinical decision support system for physicians.

Abstract
INTRODUCTION Disparities in health and healthcare access remain a major problem in the USA. The current study sought to investigate the relationship between patient insurance status and hospital selection for surgical care. METHODS Patients who underwent liver or pancreatic resection for cancer between 2004 and 2014 were identified in the National Inpatient Sample. The association of insurance status and hospital type was examined. RESULTS In total, 22,254 patients were included in the study. Compared with patients with private insurance, Medicaid patients were less likely to undergo surgery at urban non-teaching hospitals (OR = 0.36, 95%CI 0.22-0.59) and urban teaching hospitals (OR = 0.54, 95%CI 0.34-0.84) than rural hospitals. Medicaid patients were less likely to undergo surgery at private investor-owned hospitals (OR = 0.53, 95%CI 0.38-0.73) than private non-profit hospitals. In contrast, uninsured patients were 2.2-fold more likely to go to government-funded hospitals rather than private non-profit hospitals (OR = 2.19, 95%CI 1.76-2.71). CONCLUSION Insurance status was strongly associated with the type of hospital in which patients underwent surgery for liver and pancreatic cancers. Addressing the reasons for inequitable access to different hospital settings relative to insurance status is essential to ensure that all patients undergoing pancreatic or liver surgery receive high-quality surgical care.

Abstract
BACKGROUND Diabetes mellitus is a prevalent condition among hospitalized patients and the inpatient setting presents an opportunity for providers to review and adjust antihyperglycemic medications. We sought to describe practice patterns and predictors of antihyperglycemic intensification (AHI) at hospital discharge for type 2 diabetes mellitus (T2DM) patients not on home insulin. METHODS We conducted a retrospective study of adult patients with T2DM receiving either non-insulin antihyperglycemic (NIA) or no antihyperglycemic medications prior to admission who were hospitalized within two hospitals in the Johns Hopkins Health System from December 2015 to September 2016. Mean hospital glucose values and observed vs. individualized target hemoglobin A1C values (based on risk of mortality score) were used to define an indication for AHI. Multivariable logistic regression was used to identify predictors of AHI. RESULTS A total of 554 discharges of 475 unique patients were included. An indication for AHI was present in 104 (18.8%) of discharges, and AHI occurred in 30 (28.8%) of these discharges. Higher mean admission BG values and A1C, fewer pre-admission antihyperglycemic agents, involvement of the diabetes service, and admitting service were associated with AHI, while no association was observed with age, sex, race, risk of mortality and severity of illness scores, or length of stay. AHI was not associated with 30-day readmission. CONCLUSION An indication for AHI occurs relatively infrequently among hospitalized patients, but when present, AHI occurs in approximately 1 in 3 discharges. AHI appears to be related largely to the degree of hyperglycemia, and diabetes service involvement. Further studies are needed to understand the implications of AHI at hospital discharge on short and long-term outcomes in this population.

Abstract
BACKGROUND Pregnancy-related AKI (PR-AKI) is increasing in the United States. PR-AKI is associated with adverse maternal outcomes. Disparities in racial/ethnic differences in PR-AKI by race have not been studied. METHODS This was a retrospective cohort study using the National Inpatient Sample (NIS) from 2005 to 2015. We identified patients who were admitted for a pregnancy-related diagnosis using the Neomat variable provided by the NIS database that indicates the presence of a maternal or neonatal diagnosis code or procedure code. PR-AKI was identified using ICD codes. Survey logistic regression was used for multivariable analysis adjusting for age, medical comorbidities, socioeconomic factors, and hospital/admission factors. RESULTS From 48,316,430 maternal hospitalizations, 34,001 (0.07%) were complicated by PR-AKI. Hospitalizations for PR-AKI increased from 3.5/10,000 hospitalizations in 2005 to 11.8/10,000 hospitalizations in 2015 with the largest increase seen in patients aged ≥35 and black patients. PR-AKI was associated with higher odds of miscarriage (adjusted odds ratio [aOR], 1.64; 95% CI, 1.34 to 2.07) and mortality (aOR, 1.53; 95% CI, 1.25 to 1.88). After adjustment for age, medical comorbidities, and socioeconomic factors, blacks were more likely than whites to develop PR-AKI (aOR, 1.17; 95% CI, 1.04 to 1.33). On subgroup analyses in hospitalizations of patients with PR-AKI, blacks and Hispanics were more likely to have preeclampsia/eclampsia compared with whites (aOR, 1.29; 95% CI, 1.01 to 1.65; and aOR, 1.69; 95% CI, 1.23 to 2.31, respectively). Increased odds of mortality in PR-AKI compared with whites were only seen in black patients (aOR, 1.61; 95% CI, 1.02 to 2.55). CONCLUSIONS The incidence of PR-AKI has increased and the largest increase was seen in older patients and black patients. PR-AKI is associated with miscarriages, adverse discharge from hospital, and mortality. Black and Hispanic patients with PR-AKI were more likely to have adverse outcomes than white patients. Further research is needed to identify factors contributing to these discrepancies.

Abstract
BACKGROUND Patient risk adjustment is critical for hospital benchmarking and allocation of healthcare resources. However, considerable heterogeneity exists among measures. OBJECTIVES The performance of five measures was compared to predict mortality and length of stay (LOS) in hospitalized adults using claims data; these include three comorbidity composite scores (Charlson/Deyo age-comorbidity score, V W Elixhauser comorbidity score, and V W Elixhauser age-comorbidity score), 3 M risk of mortality (3 M ROM), and 3 M severity of illness (3 M SOI) subclasses. METHODS Binary logistic and zero-truncated negative binomial regression models were applied to a 2-year retrospective dataset (2013-2014) with 123,641 adult inpatient admissions from a large hospital system in New York City. RESULTS All five measures demonstrated good to strong model fit for predicting in-hospital mortality, with C-statistics of 0.74 (95% confidence interval [CI] [0.74, 0.75]), 0.80 (95% CI [0.80, 0.81]), 0.81(95% CI [0.81, 0.82]), 0.94 (95% CI [0.93, 0.94]), and 0.90 (95% CI [0.90, 0.91]) for Charlson/Deyo age-comorbidity score, V W Elixhauser comorbidity score, V W Elixhauser age-comorbidity score, 3 M ROM, and 3 M SOI, respectively. The model fit statistics to predict hospital LOS measured by the likelihood ratio index were 0.3%, 1.2%, 1.1%, 6.2%, and 4.3%, respectively. DISCUSSION The measures tested in this study can guide nurse managers in the assignment of nursing care and coordination of needed patient services and administrators to effectively and efficiently support optimal nursing care.

Abstract
Background Resistance to all first-line antibiotics necessitates the use of less effective or more toxic "reserve" agents. Gram-negative bloodstream infections (GNBSIs) harboring such difficult-to-treat resistance (DTR) may have higher mortality than phenotypes that allow for ≥1 active first-line antibiotic. Methods The Premier Database was analyzed for inpatients with select GNBSIs. DTR was defined as intermediate/resistant in vitro to all ß-lactam categories, including carbapenems and fluoroquinolones. Prevalence and aminoglycoside resistance of DTR episodes were compared with carbapenem-resistant, extended-spectrum cephalosporin-resistant, and fluoroquinolone-resistant episodes using CDC definitions. Predictors of DTR were identified. The adjusted relative risk (aRR) of mortality was examined for DTR, CDC-defined phenotypes susceptible to ≥1 first-line agent, and graded loss of active categories. Results Between 2009-2013, 471 (1%) of 45011 GNBSI episodes at 92 (53.2%) of 173 hospitals exhibited DTR, ranging from 0.04% for Escherichia coli to 18.4% for Acinetobacter baumannii. Among patients with DTR, 79% received parenteral aminoglycosides, tigecycline, or colistin/polymyxin-B; resistance to all aminoglycosides occurred in 33%. Predictors of DTR included urban healthcare and higher baseline illness. Crude mortality for GNBSIs with DTR was 43%; aRR was higher for DTR than for carbapenem-resistant (1.2; 95% confidence interval, 1.0-1.4; P = .02), extended-spectrum cephalosporin-resistant (1.2; 1.1-1.4; P = .001), or fluoroquinolone-resistant (1.2; 1.0-1.4; P = .008) infections. The mortality aRR increased 20% per graded loss of active first-line categories, from 3-5 to 1-2 to 0. Conclusion Nonsusceptibility to first-line antibiotics is associated with decreased survival in GNBSIs. DTR is a simple bedside prognostic measure of treatment-limiting coresistance.

Abstract
PURPOSE Despite advances in biologic therapy, approximately 10-15% of ulcerative colitis (UC) patients require surgery. We aimed to (1) examine the rates of emergent colectomy and elective ileal pouch anal anastomosis (IPAA) over time among UC patients in the USA and (2) investigate disparities in surgery rates by patient demographics. METHODS Data from the Nationwide Inpatient Sample (NIS) from 2000 to 2014 were analyzed. Inclusion criteria were admissions with a primary UC ICD-9-CM diagnosis code and age > 18. Emergent cases were defined as those admitted through the emergency room with an outcome ICD-9-CM code for subtotal colectomy. Elective IPAA cases were defined with an outcome ICD-9-CM code for IPAA, used as a surrogate measure of colectomy. Patient and hospital-level demographics were analyzed. Temporal trends of colectomy were analyzed utilizing joinpoint-regression analysis with calculation of annual percentage change (APC). RESULTS A total of 470,708 admissions were included over the 14-year period. Emergent colectomy rate significantly declined (APC - 7.35%, p = 0.0002), while the rate of elective IPAA remained stable (APC - 0.21%, p = 0.8). Emergent colectomy rates declined similarly across all demographics, though not as marked among patients age 50 and older and Medicare patients. Elective IPAA rates were significantly lower among blacks and patients with public insurance. CONCLUSIONS There has been a significant decline in emergent UC colectomy rates in the USA; however, the overall need for surgery appears unchanged given stable IPAA rates. This suggests a limited impact on overall surgery rates with a shift from emergent to elective procedures.

Impact of Telemedicine on Mortality, Length of Stay, and Cost Among Patients in Progressive Care Units: Experience From a Large Healthcare System. Crit Care Med 2019; 46:728-735. [PMID: 29384782 PMCID: PMC5908255 DOI: 10.1097/ccm.0000000000002994] [Citation(s) in RCA: 44] [Impact Index Per Article: 8.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/25/2022]
Abstract
Objectives: To determine whether Telemedicine intervention can affect hospital mortality, length of stay, and direct costs for progressive care unit patients. Design: Retrospective observational. Setting: Large healthcare system in Florida. Patients: Adult patients admitted to progressive care unit (PCU) as their primary admission between December 2011 and August 2016 (n = 16,091). Interventions: Progressive care unit patients with telemedicine intervention (telemedicine PCU [TPCU]; n = 8091) and without telemedicine control (nontelemedicine PCU [NTPCU]; n = 8000) were compared concurrently during study period. Measurements and Main Results: Primary outcome was progressive care unit and hospital mortality. Secondary outcomes were hospital length of stay, progressive care unit length of stay, and mean direct costs. The mean age NTPCU and TPCU patients were 63.4 years (95% CI, 62.9–63.8 yr) and 71.1 years (95% CI, 70.7–71.4 yr), respectively. All Patient Refined-Diagnosis Related Group Disease Severity (p < 0.0001) and All Patient Refined-Diagnosis Related Group patient Risk of Mortality (p < 0.0001) scores were significantly higher among TPCU versus NTPCU. After adjusting for age, sex, race, disease severity, risk of mortality, hospital entity, and organ systems, TPCU survival benefit was 20%. Mean progressive care unit length of stay was lower among TPCU compared with NTPCU (2.6 vs 3.2 d; p < 0.0001). Postprogressive care unit hospital length of stay was longer for TPCU patients, compared with NTPCU (7.3 vs 6.8 d; p < 0.0001). The overall mean direct cost was higher for TPCU ($13,180), compared with NTPCU ($12,301; p < 0.0001). Conclusions: Although there are many studies about the effects of telemedicine in ICU, currently there are no studies on the effects of telemedicine in progressive care unit settings. Our study showed that TPCU intervention significantly decreased mortality in progressive care unit and hospital and progressive care unit length of stay despite the fact patients in TPCU were older and had higher disease severity, and risk of mortality. Increased postprogressive care unit hospital length of stay and total mean direct costs inclusive of telemedicine costs coincided with improved survival rates. Telemedicine intervention decreased overall mortality and length of stay within progressive care units without substantial cost incurrences.

The Lipid Paradox Among Acute Ischemic Stroke Patients-A Retrospective Study of Outcomes and Complications. MEDICINA (KAUNAS, LITHUANIA) 2019; 55:medicina55080475. [PMID: 31412670 PMCID: PMC6723697 DOI: 10.3390/medicina55080475] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/24/2019] [Revised: 07/23/2019] [Accepted: 08/13/2019] [Indexed: 12/02/2022]
Abstract
Background and objectives: The Studies have suggested hypercholesterolemia is a risk factor for cerebrovascular disease. However, few of the studies with a small number of patients had tested the effect of hypercholesterolemia on the outcomes and complications among acute ischemic stroke (AIS) patients. We hypothesized that lipid disorders (LDs), though risk factors for AIS, were associated with better outcomes and fewer post-stroke complications. Materials and Method: We performed a retrospective analysis of the Nationwide Inpatient Sample (years 2003–2014) in adult hospitalizations for AIS to determine the outcomes and complications associated with LDs, using ICD-9-CM codes. In 2014, we also aimed to estimate adjusted odds of AIS in patients with LDs compared to patients without LDs. The multivariable survey logistic regression models, weighted to account for sampling strategy, were fitted to evaluate relationship of LDs with AIS among 2014 hospitalizations, and outcomes and complications amongst AIS patients from 2003–2014. Results and Conclusions: In 2014, there were 28,212,820 (2.02% AIS and 5.50% LDs) hospitalizations. LDs patients had higher prevalence and odds of having AIS compared with non-LDs. Between 2003–2014, of the total 4,224,924 AIS hospitalizations, 451,645 (10.69%) had LDs. Patients with LDs had lower percentages and odds of mortality, risk of death, major/extreme disability, discharge to nursing facility, and complications including epilepsy, stroke-associated pneumonia, GI-bleeding and hemorrhagic-transformation compared to non-LDs. Although LDs are risk factors for AIS, concurrent LDs in AIS is not only associated with lower mortality and disability but also lower post-stroke complications and higher chance of discharge to home.

Abstract
Background and Objectives: Inadequate vitamin D and calcium intake have been linked to many health issues including chronic headaches. Some studies suggested an association between low vitamin D levels and increase the risk of frequent headaches in middle-aged and older men; however, no single study reported the role of these deficiencies in migraine patients. We aimed to investigate the association of hypocalcemia and vitamin D deficiency with migraine hospitalizations. Materials and Methods: A population-based retrospective cross-sectional analysis of the Nationwide Inpatient Sample (NIS) (years 2003–2014) in migraine hospitalizations was performed. The prevalence, demographic characteristics and All Patient Refined Diagnosis Related Groups severity/disability association were compared in patients with hypocalcemia and vitamin D deficiency to those without deficiencies, using ICD-9-CM codes. Weighted analyses using Chi-Square, paired Student’s t-test, and Cochran–Armitage trend test were performed. Survey logistic regression was performed to find an association between deficiencies and migraine hospitalizations and deficiency induced disability amongst migraineurs. Results: Between years 2003 and 2014, of the total 446,446 migraine hospitalizations, 1226 (0.27%) and 2582 (0.58%) presented with hypocalcemia and vitamin D deficiency, respectively. In multivariable analysis, hypocalcemia [Odds Ratio (OR): 6.19; Confidence Interval (CI): 4.40–8.70; p < 0.0001] and vitamin D deficiency (OR: 3.12; CI: 2.38–4.08; p < 0.0001) were associated with markedly elevated odds of major/extreme loss of function. There was higher prevalence (3.0% vs. 1.5% vs. 1.6%; p < 0.0001) and higher odds of migraine among vitamin D deficiency (OR: 1.97; CI: 1.89–2.05; p < 0.0001) patients in comparison to patients with hypocalcemia (OR: 1.11; CI: 1.03–1.20; p = 0.0061) and no-deficiency, respectively. Conclusions: In this study, we demonstrated a significant association between hypocalcemia and vitamin D deficiency with migraine attacks and deficiency induced loss of function among migraineurs. Early preventive measures may reduce the disability in migraineurs.

Abstract
BACKGROUND Hypernatremia is one of the most common electrolyte disturbances following aneurysmal subarachnoid hemorrhage (aSAH) and has been correlated with increased mortality in single institution studies. We investigated this association using a large nationwide healthcare database. METHODS We performed a retrospective analysis of adults between 2002 and 2011 with a primary diagnosis of aSAH using the Nationwide Inpatient Sample (NIS). Patients were grouped according to whether or not an inpatient diagnosis of hypernatremia was present. The primary outcome was the NIS-SAH outcome measure. Secondary outcomes included in-hospital mortality, length of stay (LOS), and non-routine hospital discharge. Outcomes analyses adjusted for SAH severity using the NIS-SAH Severity Score, Charlson Comorbidity Index, and the presence of cerebral edema. RESULTS A total of 18,377 patients were included in the study. The incidence of a poor outcome as defined by the NIS-SAH outcome measure was 65.9% in the hypernatremia group and 33.4% in the normonatremia group (OR 1.96, 95% CI 1.68 - 2.27). There was higher mortality in the hypernatremia group (OR 1.60, 95% CI 1.37 - 1.87). Patients with hypernatremia had a significantly higher rate of non-routine hospital discharge and gastrostomy. The incidences of poor outcome, in-hospital mortality, and non-routine disposition were higher in the hypernatremia group regardless of treatment type (clipping vs. endovascular embolization). Pulmonary complications and acute kidney injury were more common in the hypernatremia group as well. CONCLUSIONS In patients with aSAH, hypernatremia is associated with poorer functional outcomes regardless of SAH severity.

Abstract
Background Sepsis management guidelines endorse use of biomarkers to support clinical assessment and treatment decisions in septic patients. The impact of biomarkers on improving patient outcomes remains uncertain. Methods Retrospective observational study of adult sepsis discharges between January 1, 2012, and December 31, 2015, from Premier Healthcare Database hospitals. Sepsis was defined by an All Patients Refined Diagnosis-Related Group code of 720 (septicemia and disseminated infections). Use of four biomarker strategies was evaluated based on hospital records: (i) >1 procalcitonin (PCT), (ii) 1 PCT, (iii) no PCT but ≥1 C-reactive protein (CRP) and/or lactate and (iv) no sepsis biomarkers. Associations between biomarker use and clinical and cost outcomes were examined. The primary outcome was impact of biomarker strategy on hospital costs per day. Results Among 933,591 adult sepsis discharges during the study period, 731,392 (78%) had biomarker tests ordered. In multivariable analyses, discharges with >1 PCT had higher hospital costs per day ($1,904; 95% confidence interval [CI] $1,896–$1,911) compared with discharges with no sepsis biomarkers ($1,606; 95% CI $1,658–$1,664). Discharges with >1 PCT also had greater illness severity and antimicrobial exposure compared with other biomarker-use groups. The adjusted odds of dying during hospital stay compared with being discharged were significantly lower for sepsis discharges with >1 PCT (0.64; 95% CI 0.61–0.67) and 1 PCT (0.88; 95% CI 0.85–0.91) compared with no sepsis biomarker use. The proportion of discharges with ≥1 PCT increased almost six-fold during the study; use of other biomarkers remained constant. Conclusions Between 2012 and 2015, PCT use among sepsis discharges increased six-fold while lactate and CRP use remained unchanged. PCT use was associated with decreased odds of in-hospital mortality but increased hospital costs per day. Serial biomarker monitoring may be associated with improved patient outcomes in the most critically ill septic patients.

Abstract
BACKGROUND International trials suggest benefit of revascularization surgery (RS) for moyamoya disease (MMD). However, nationally representative US data on demographics and outcomes after RS in MMD are lacking. AIMS To estimate causes and rates of readmission after RS for MMD. METHODS In the Nationwide Readmissions Database, index admissions for ECICB for MMD and readmissions for ischemic stroke (IS), subarachnoid hemorrhage (SAH), and intracerebral hemorrhage (ICH) were identified using validated International Classification of Diseases, Ninth Revision, Clinical Modification codes. We summarized demographics and comorbidities, and calculated 30-, 60-, and 90-day readmission rates per 100,000 index admissions. RESULTS Among 201 index admissions for RS for MMD, mean age (SD) was 41.7 (12.6) years; 75% were female; 24% had diabetes; 53% had hypertension; 40% had hypercholesterolemia; 3% had ICH; 16% had IS; and 1% had SAH. RS was performed at large hospitals in 83%, urban hospitals in 85%, and teaching hospitals in 97%. 80% were discharged home. 34% had a readmission during follow-up. Leading reasons for readmission up to 90 days included MMD (62%), postoperative infection (10%), sickle cell crisis (4%), ischemic stroke (4%), epilepsy (2%), subdural hemorrhage (2%) and headache (2%). Readmission rates (per 100,000 index admissions) were 559 at 30 days, 1829 at 60 days, and 2027 at 90 days for IS. There were no readmissions for SAH or ICH. CONCLUSIONS This analysis of nationally representative US data suggests that although readmission after RS for MMD is not uncommon, cerebral hemorrhagic events during the 90-day postoperative period are rare.

Abstract
BACKGROUND Although mounting evidence supports the use of palliative care (PC) to improve care experiences and quality of life for oncology patients, the frequency of and factors associated with PC use during oncology-related hospitalizations remain unknown. MATERIALS AND METHODS Using the National Inpatient Sample dataset, hospitalizations during 2012-2014 for a primary diagnosis of cancer with high risk of in-hospital mortality were identified. PC use was identified using the V66.7 ICD-9 code. Factors associated with the cost of hospitalization were identified using multivariable gamma regression. RESULTS During the study period, 124,186 hospitalizations were identified with a primary diagnosis of malignancy (melanoma, breast, colon, gynecologic, prostate, male genitourinary, head/neck, urinary tract, noncolon gastrointestinal, lung, brain, bone/soft tissue, endocrine, or nonlung thoracic). Most patients were treated at a teaching hospital (51-77% by cancer type), and use of PC ranged from 10% for patients with endocrine cancers to 31% for patients with melanoma. Patients utilizing PC had a lower frequency of operative procedures (4-33% vs. 34-79% by cancer type, all p ≤ 0.001), a higher rate of in-hospital death (30-45% vs. 4-10% by cancer type, all p < 0.001), and a lower total hospitalization cost (median: $5076-17,151 vs. $10,918-29,287 by cancer type, p ≤ 0.01 except male genitourinary). In an adjusted analysis, the cost of hospitalization was significantly associated (all p < 0.001) with patient gender, race, age, operative, in-hospital death, extended length of stay, and PC. CONCLUSIONS In summary, inpatient PC utilization varied by cancer type. PC was associated with lower utilization of surgical procedures, shorter length of stay, and lower hospitalization cost. Lower hospitalization cost was also seen for patients who were older, female, or African American.

Abstract
Background Community-acquired pneumonia (CAP) is a common cause of hospitalization. While there are single-center studies on acute kidney injury requiring dialysis (AKI-D) and CAP, data on national trends and outcomes regarding AKI-D in CAP hospitalizations is lacking. Methods We utilized the Nationwide Inpatient Sample to analyze trends overall and within subgroups. We also utilized multivariate regression to adjust for potential confounders of annual trends and to generate adjusted odds ratios (aOR) for predictors and outcomes, including mortality and adverse discharge. Results There were 11,500,456 pneumonia hospitalizations between 2002 and 2013, of which 3675 (0.3%) were complicated by AKI-D. The AKI-D rate increased from 2.7/1000 hospitalizations in 2002 to 4.3/1000 hospitalizations in 2013. The rate of increase was higher in males and African Americans. Although temporal changes in demographics and comorbidities explained a substantial proportion, they could not explain the entire trend. The predictor with the highest odds of AKI-D required mechanical ventilation during hospitalization (aOR 12.47; 95% CI 11.66-13.34). Other significant predictors included sepsis (aOR 4.37; 95% CI 4.09-4.66), heart failure (aOR 2.40; 95% CI 2.25-2.55), and chronic kidney disease (CKD) (aOR 2.00; 95% CI 1.86-2.16). AKI-D was associated with increased in-hospital mortality (aOR 3.08; 95% CI 2.88-3.30) and adverse discharge (aOR 2.09; 95% CI 1.92-2.26). Although adjusted mortality decreased per year, attributable mortality remained stable. Conclusion Pneumonia hospitalizations complicated by AKI-D have increased with a differential increase by demographic groups. AKI-D is associated with significant morbidity and mortality. In the absence of effective AKI-D therapies, the focus should be on early risk stratification and prevention to avoid this devastating complication.

Abstract
The number of patients with advanced heart failure receiving left ventricular assist device (LVAD) implantation has increased dramatically over the last decade. There are limited data available about the nationwide trends of complications leading to readmissions after implantation of contemporary devices. Patients who underwent LVAD implantation from January 2013 to December 2013 were identified using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) code 37.66 from the Healthcare Cost and Utilization Project's National Readmission Database. The top causes of unplanned 30-day readmission after LVAD implantation were determined. Survey logistic regression was used to analyze the significant predictors of readmission. In 2013, there were 2,235 patients with an LVAD implantation. Of them, 665 (29.7%) had at least 1 unplanned readmission within 30 days, out of which 289 (43.4%) occurred within 10 days after discharge. Implant complications (14.9%), congestive heart failure (11.7%), and gastrointestinal bleeding (8.4%) were the top 3 diagnoses for the first readmission and accounted for more than a third of all readmissions. Significant predictors of readmissions included a prolonged length of stay during the index admission, Medicare insurance, and discharge to short-term facility. In conclusion, despite increased experience with LVADs, unplanned readmissions within 30 days of implantation remain significantly high.

Nationwide Trends in Hospital Outcomes and Utilization After Lower Limb Revascularization in Patients on Hemodialysis. JACC Cardiovasc Interv 2018; 10:2101-2110. [PMID: 29050629 DOI: 10.1016/j.jcin.2017.05.050] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2016] [Revised: 04/24/2017] [Accepted: 05/21/2017] [Indexed: 11/24/2022]
Abstract
OBJECTIVES This study aimed to describe the temporal trends and outcomes of endovascular and surgical revascularization in a large, nationally representative sample of patients with end-stage renal disease on hemodialysis hospitalized for peripheral artery disease (PAD). BACKGROUND PAD is prevalent among patients with end-stage renal disease on hemodialysis and is associated with significant morbidity and mortality. There is a paucity of information on trends in endovascular and surgical revascularization and post-procedure outcomes in this population. METHODS We used the Nationwide Inpatient Sample (2002 to 2012) to identify hemodialysis patients undergoing endovascular or surgical procedures for PAD using diagnostic and procedural codes. We compared trends in amputation, post-procedure complications, mortality, length of stay, and costs between the 2 groups using trend tests and logistic regression. RESULTS There were 77,049 endovascular and 29,556 surgical procedures for PAD in hemodialysis patients. Trend analysis showed that endovascular procedures increased by nearly 3-fold, whereas there was a reciprocal decrease in surgical revascularization. Post-procedure complication rates were relatively stable in persons undergoing endovascular procedures but nearly doubled in those undergoing surgery. Surgery was associated with 1.8 times adjusted odds (95% confidence interval: 1.60 to 2.02) for complications and 1.6 times the adjusted odds for amputations (95% confidence interval: 1.40 to 1.75) but had similar mortality (adjusted odds ratio: 1.05; 95% confidence interval: 0.85 to 1.29) compared with endovascular procedures. Length of stay for endovascular procedures remained stable, whereas a decrease was seen for surgical procedures. Overall costs increased marginally for both procedures. CONCLUSIONS Rates of endovascular procedures have increased, whereas those of surgeries have decreased. Surgical revascularization is associated with higher odds of overall complications. Further prospective studies and clinical trials are required to analyze the relationship between the severity of PAD and the revascularization strategy chosen.

Effects of chlorhexidine gluconate oral care on hospital mortality: a hospital-wide, observational cohort study. Intensive Care Med 2018; 44:1017-1026. [PMID: 29744564 PMCID: PMC6061438 DOI: 10.1007/s00134-018-5171-3] [Citation(s) in RCA: 90] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2018] [Accepted: 04/07/2018] [Indexed: 01/17/2023]
Abstract
Purpose Chlorhexidine oral care is widely used in critically and non-critically ill hospitalized patients to maintain oral health. We investigated the effect of chlorhexidine oral care on mortality in a general hospitalized population. Methods In this single-center, retrospective, hospital-wide, observational cohort study we included adult hospitalized patients (2012–2014). Mortality associated with chlorhexidine oral care was assessed by logistic regression analysis. A threshold cumulative dose of 300 mg served as a dichotomic proxy for chlorhexidine exposure. We adjusted for demographics, diagnostic category, and risk of mortality expressed in four categories (minor, moderate, major, and extreme). Results The study cohort included 82,274 patients of which 11,133 (14%) received chlorhexidine oral care. Low-level exposure to chlorhexidine oral care (≤ 300 mg) was associated with increased risk of death [odds ratio (OR) 2.61; 95% confidence interval (CI) 2.32–2.92]. This association was stronger among patients with a lower risk of death: OR 5.50 (95% CI 4.51–6.71) with minor/moderate risk, OR 2.33 (95% CI 1.96–2.78) with a major risk, and a not significant OR 1.13 (95% CI 0.90–1.41) with an extreme risk of mortality. Similar observations were made for high-level exposure (> 300 mg). No harmful effect was observed in ventilated and non-ventilated ICU patients. Increased risk of death was observed in patients who did not receive mechanical ventilation and were not admitted to ICUs. The adjusted number of patients needed to be exposed to result in one additional fatality case was 47.1 (95% CI 45.2–49.1). Conclusions These data argue against the indiscriminate widespread use of chlorhexidine oral care in hospitalized patients, in the absence of proven benefit in specific populations.

Validation of the All Patient Refined Diagnosis Related Group (APR-DRG) Risk of Mortality and Severity of Illness Modifiers as a Measure of Perioperative Risk. J Med Syst 2018; 42:81. [PMID: 29564554 DOI: 10.1007/s10916-018-0936-3] [Citation(s) in RCA: 74] [Impact Index Per Article: 12.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2017] [Accepted: 03/14/2018] [Indexed: 10/17/2022]
Abstract
The All Patient Refined Diagnosis Related Group (APR-DRG) is an inpatient visit classification system that assigns a diagnostic related group, a Risk of Mortality (ROM) subclass and a Severity of Illness (SOI) subclass. While extensively used for cost adjustment, no study has compared the APR-DRG subclass modifiers to the popular Charlson Comorbidity Index as a measure of comorbidity severity in models for perioperative in-hospital mortality. In this study we attempt to validate the use of these subclasses to predict mortality in a cohort of surgical patients. We analyzed all adult (age over 18 years) inpatient non-cardiac surgery at our institution between December 2005 and July 2013. After exclusions, we split the cohort into training and validation sets. We created prediction models of inpatient mortality using the Charlson Comorbidity Index, ROM only, SOI only, and ROM with SOI. Models were compared by receiver-operator characteristic (ROC) curve, area under the ROC curve (AUC), and Brier score. After exclusions, we analyzed 63,681 patient-visits. Overall in-hospital mortality was 1.3%. The median number of ICD-9-CM diagnosis codes was 6 (Q1-Q3 4-10). The median Charlson Comorbidity Index was 0 (Q1-Q3 0-2). When the model was applied to the validation set, the c-statistic for Charlson was 0.865, c-statistic for ROM was 0.975, and for ROM and SOI combined the c-statistic was 0.977. The scaled Brier score for Charlson was 0.044, Brier for ROM only was 0.230, and Brier for ROM and SOI was 0.257. The APR-DRG ROM or SOI subclasses are better predictors than the Charlson Comorbidity Index of in-hospital mortality among surgical patients.

Abstract
OBJECTIVES/HYPOTHESIS Examine rates of readmission after total laryngectomy and determine primary etiologies, timing, and risk factors for unplanned readmission. STUDY DESIGN Retrospective cohort study. METHODS The Nationwide Readmissions Database was queried for patients who underwent total laryngectomy between January 2013 and November 2013. Patient-, procedure-, admission-, and institution-level characteristics were compared for patients with and without unplanned 30-day readmission. Outcomes of interest included rates, etiology, and timing of readmission. Multivariate logistic regression was used to identify predictors of 30-day readmission. RESULTS There were 2,931 total laryngectomies performed in 2013 with an unplanned readmission rate of 17.5%. Postoperative fistula accounted for 13.7% of readmissions. The odds of readmission were elevated for patients undergoing concurrent procedures, including primary tracheoesophageal fistulization (adjusted odds ratio [aOR]: 2.44, 95% confidence interval [CI]: 1.15-5.18, P = .02) and/or pedicle graft or flap procedures (aOR: 1.73, 95% CI: 1.13-2.66, P = .01). Additionally, patients with comorbid coagulopathy (aOR: 3.04, 95% CI: 1.13-8.22, P = .03), liver disease (aOR: 2.48, 95% CI: 1.08-5.71, P = .03), and valvular heart disease (aOR: 3.18, 95% CI: 1.20-8.41, P = .02) had increased risk for unplanned 30-day readmission. Private insurance and longer lengths of stay were associated with decreased odds of readmission. CONCLUSIONS Nearly one-fifth of total laryngectomy patients are readmitted to the hospital within 30 days of discharge. Risk factors identified in this nationally representative cohort should be carefully considered during the postoperative period to reduce preventable readmissions after total laryngectomy. LEVEL OF EVIDENCE 2c Laryngoscope, 1842-1850, 2018.

Incidence, Predictors, and Outcomes of Ventriculostomy-Associated Infections in Spontaneous Intracerebral Hemorrhage. Neurocrit Care 2017; 24:389-96. [PMID: 26337068 DOI: 10.1007/s12028-015-0199-5] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 10/23/2022]
Abstract
BACKGROUND The impact of ventriculostomy-associated infections (VAI) on intracerebral hemorrhage (ICH) outcomes has not been clearly established, although prior studies have attempted to address the incidence and predictors of VAI. We aimed to explore VAI characteristics and its effect on ICH outcomes at a population level. METHODS ICH patients requiring ventriculostomy with and without VAI were identified from 2002 to 2011 Nationwide Inpatient Sample using ICD-9 codes. A retrospective cohort study was performed. Demographics, comorbidities, hospital characteristics, inpatient outcomes, and resource utilization measures were compared between the two groups. Pearson's Chi-square and Wilcoxon-Mann-Whitney tests were used for categorical and continuous variables, respectively. Logistic regression was used to analyze the predictors of VAI. RESULTS We included 34,238 patients in the analysis, of whom 1934 (5.6 %) had VAI. The rate of ventriculostomy utilization in ICH increased from 5.7 % in 2002-2003 to 7.0 % in 2010-2011 (trend p < 0.001) and the rate of VAI also showed a gradual upward trend from 6.1 to 7.0 % across the same interval (trend p < 0.001). The VAI group had significantly higher inpatient mortality (41.2 vs. 36.5 %, p < 0.001) and it remained higher after controlling for baseline demographics, hospital characteristics, comorbidity, and systemic infections (adjusted OR 1.38, 95 % CI 1.22-1.46, p < 0.001). The VAI group had longer length of hospital stay and higher inflation adjusted cost of care. Predictors of VAI included higher age, males, higher Charlson's comorbidity scores, longer length of stay, and presence of systemic infections mainly pneumonia and sepsis. CONCLUSION VAI resulted in higher inpatient mortality, more unfavorable discharge disposition, and higher resource utilization measures in ICH patients. Steps to mitigate VAI may help improve ICH outcomes and decrease hospital costs.

Abstract
BACKGROUND AND OBJECTIVES Patients on hemodialysis have high 30-day unplanned readmission rates. Using a national all-payer administrative database, we describe the epidemiology of 30-day unplanned readmissions in patients on hemodialysis, determine concordance of reasons for initial admission and readmission, and identify predictors for readmission. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This is a retrospective cohort study using the Nationwide Readmission Database from the year 2013 to identify index admissions and readmission in patients with ESRD on hemodialysis. The Clinical Classification Software was used to categorize admission diagnosis into mutually exclusive clinically meaningful categories and determine concordance of reasons for admission on index hospitalizations and readmissions. Survey logistic regression was used to identify predictors of at least one readmission. RESULTS During 2013, there were 87,302 (22%) index admissions with at least one 30-day unplanned readmission. Although patient and hospital characteristics were statistically different between those with and without readmissions, there were small absolute differences. The highest readmission rate was for acute myocardial infarction (25%), whereas the lowest readmission rate was for hypertension (20%). The primary reasons for initial hospitalization and subsequent 30-day readmission were discordant in 80% of admissions. Comorbidities that were associated with readmissions included depression (odds ratio, 1.10; 95% confidence interval [95% CI], 1.05 to 1.15; P<0.001), drug abuse (odds ratio, 1.41; 95% CI, 1.31 to 1.51; P<0.001), and discharge against medical advice (odds ratio, 1.57; 95% CI, 1.45 to 1.70; P<0.001). A group of high utilizers, which constituted 2% of the population, was responsible for 20% of all readmissions. CONCLUSIONS In patients with ESRD on hemodialysis, nearly one quarter of admissions were followed by a 30-day unplanned readmission. Most readmissions were for primary diagnoses that were different from initial hospitalization. A small proportion of patients accounted for a disproportionate number of readmissions.

Abstract
Objective To examine rates of readmission after parathyroidectomy in patients with chronic kidney disease and determine primary etiologies, timing, and risk factors for these unplanned readmissions. Study Design Retrospective cohort study. Setting Nationwide Readmissions Database. Subjects and Methods The Nationwide Readmissions Database was queried for parathyroidectomy procedures performed in patients with chronic kidney disease between January 2013 and November 2013. Patient-, admission-, and hospital-level characteristics were compared for patients with and without at least 1 unplanned 30-day readmission. Outcomes of interest included rates, etiology, and timing of readmission. Multivariate logistic regression was used to identify predictors of 30-day readmission. Results There were 2756 parathyroidectomies performed in patients with chronic kidney disease with an unplanned readmission rate of 17.2%. Hypocalcemia/hungry bone syndrome accounted for 40% of readmissions. Readmissions occurred uniformly throughout the 30 days after discharge, but readmissions for hypocalcemia/hungry bone syndrome peaked in the first 10 days and decreased over time. Weight loss/malnutrition at time of parathyroidectomy and length of stay of 5 to 6 days conferred increased risk of readmission with adjusted odds ratios (aOR) of 3.31 (95% confidence interval [CI], 1.55-7.05; P = .002) and 1.87 (95% CI, 1.10-3.19; P = .02), respectively. Relative to primary hyperparathyroidism, parathyroidectomies performed for secondary hyperparathyroidism (aOR, 2.53; 95% CI, 1.07-5.95; P = .03) were associated with higher risk of readmission. Conclusion Postparathyroidectomy readmission rates for patients with chronic kidney disease are nearly 5 times that of the general population. Careful consideration of postoperative care and electrolyte management is crucial to minimize preventable readmissions in this vulnerable population.

Abstract
BACKGROUND AND PURPOSE Substantial variability exists in the use of life-prolonging treatments for patients with stroke, especially near the end of life. This study explores patterns of palliative care utilization and death in hospitalized patients with stroke across the United States. METHODS Using the 2010 to 2012 nationwide inpatient sample databases, we included all patients discharged with stroke identified by International Classification of Diseases-Ninth Revision codes. Strokes were subclassified as ischemic, intracerebral, and subarachnoid hemorrhage. We compared demographics, comorbidities, procedures, and outcomes between patients with and without a palliative care encounter (PCE) as defined by the International Classification of Diseases-Ninth Revision code V66.7. Pearson χ2 test was used for categorical variables. Multivariate logistic regression was used to account for hospital, regional, payer, and medical severity factors to predict PCE use and death. RESULTS Among 395 411 patients with stroke, PCE was used in 6.2% with an increasing trend over time (P<0.05). We found a wide range in PCE use with higher rates in patients with older age, hemorrhagic stroke types, women, and white race (all P<0.001). Smaller and for-profit hospitals saw lower rates. Overall, 9.2% of hospitalized patients with stroke died, and PCE was significantly associated with death. Length of stay in decedents was shorter for patients who received PCE. CONCLUSIONS Palliative care use is increasing nationally for patients with stroke, especially in larger hospitals. Persistent disparities in PCE use and mortality exist in regards to age, sex, race, region, and hospital characteristics. Given the variations in PCE use, especially at the end of life, the use of mortality rates as a hospital quality measure is questioned.

Abstract
OBJECTIVES Case volume-outcome associations bolster arguments to regionalize severe sepsis care, an approach that may necessitate interhospital patient transfers. Although transferred patients may most closely reflect care processes involved with regionalization, associations between sepsis case volume and outcomes among transferred patients are unclear. We investigated case volume-outcome associations among patients with severe sepsis transferred from another hospital. DESIGN Serial cross-sectional study using the Nationwide Inpatient Sample. SETTING United States nonfederal hospitals, years 2003-2011. PATIENTS One hundred forty-one thousand seven hundred seven patients (weighted national estimate of 717,732) with severe sepsis transferred from another acute care hospital. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS We examined associations between quintiles of annual hospital severe sepsis case volume for the receiving hospital and in-hospital mortality among transferred patients with severe sepsis. Secondary outcomes included hospital length of stay and total charges. Transferred patients accounted for 13.2% of hospitalized severe sepsis cases. In-hospital mortality was 33.2%, with median length of stay 11 days (interquartile range, 5-22), and median total charge $70,722 (interquartile range, $30,591-$159,013). Patients transferred to highest volume hospitals had higher predicted mortality risk, greater number of acutely dysfunctional organs, and lower adjusted in-hospital mortality when compared with the lowest-volume hospitals (odds ratio, 0.80; 95% CI, 0.67-0.90). In stratified analysis (p < 0.001 for interaction of case volume by organ failure), mortality benefit associated with case volume was limited to patients with single organ dysfunction (n = 48,607, 34.3% of transfers) (odds ratio, 0.66; 95% CI, 0.55-0.80). Treatment at highest volume hospitals was significantly associated with shorter adjusted length of stay (incidence rate ratio, 0.86; 95% CI, 0.75-0.98) but not costs (% charge difference, 95% CI: [-]18.8, [-]37.9 to [+]0.3). CONCLUSIONS Hospital mortality was lowest among patients with severe sepsis who were transferred to high-volume hospitals; however, case volume benefits for transferred patients may be limited to patients with lower illness severity.

Reasons for admission and predictors of national 30-day readmission rates in patients with end-stage renal disease on peritoneal dialysis. Clin Kidney J 2017; 10:552-559. [PMID: 28852495 PMCID: PMC5569698 DOI: 10.1093/ckj/sfx011] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2016] [Accepted: 01/30/2017] [Indexed: 12/23/2022] Open
Abstract
Background The number of patients with end-stage renal disease (ESRD) on peritoneal dialysis (PD) has increased by over 30% between 2007 and 2014. The Centers for Medicare and Medicaid has identified readmissions in ESRD patients to be a quality measure; however, there is a paucity of studies examining readmissions in PD patients. Methods Utilizing the National Readmission Database for the year 2013, we aimed to determine reasons for admission, the associated rates of unplanned readmission and independent predictors of readmissions in PD patients. Results The top 10 reasons for initial hospitalization were implant/PD catheter complications (23.22%), hypertension (5.47%), septicemia (5.18%), diabetes mellitus (DM) (5.12%), complications of surgical procedures/medical care (3.50%), fluid and electrolyte disorders (4.29%), peritonitis (3.76%), congestive heart failure (3.25%), pneumonia (2.90%) and acute myocardial infarction (AMI) (2.01%). The overall 30-day readmission rate was 14.6%, with the highest rates for AMI (21.8%), complications of surgical procedure/medical care (19.6%) and DM (18.4%). Concordance among the top 10 reasons for index admission and readmission was 22.6% and varied by admission diagnosis. Independent predictors of readmissions included age 35–49 years compared with 18–34 years [adjusted odds ratio (aOR) 1.35; 95% confidence interval (CI) 1.09–1.68; P = 0.006], female gender (aOR 1.27; 95% CI 1.12–1.44; P < 0.001), and comorbidities including liver disease (aOR 1.39; 95% CI 1.07–1.81; P = 0.01), peripheral vascular disease (aOR 1.33; 95% CI 1.14–1.56; P < 0.001) and depression (aOR 1.22; 95% CI 1.00–1.48; P = 0.04). Conclusions This study demonstrates the most common reasons for admission and readmissions in PD patients and several comorbidities that are predictive of readmissions. Targeted interventions towards these patients may be of benefit in reducing readmission in this growing population.

Abstract
BACKGROUND ICU admission is uncommon among obstetric patients. Nevertheless, the epidemiology of ICU utilization is considered to be a useful proxy for study of severe maternal morbidity and near-miss events. However, there is paucity of population-level studies in obstetric patients in the United States. METHODS The Texas Inpatient Public Use Data File and state-based reports were used to identify pregnancy-associated hospitalizations and those involving admission to ICU (n = 158,410) for the years 2001 - 2010. The clinical characteristics, outcomes, and the overall incidence and temporal trends of ICU admission were examined and stratified analyses of pregnancy outcomes were performed in specific categories of pregnancy-associated hospitalizations. In addition, ICU utilization among hospitalizations with maternal complications and organ dysfunction was evaluated. RESULTS Chronic comorbidities (9.7%) and presence of organ dysfunction (6.2%) were uncommon among ICU admissions, with 26.5% having high severity of illness. The incidence of ICU admission was 39.0 per 1,000 pregnancy-associated hospitalizations-years. Marked variability was found in ICU admission both across pregnancy outcomes (ranging from 0.6 per 1,000 abortions-years to 85.9 per 1,000 stillbirths-years) and categories of pregnancy-associated hospitalizations (ranging from 32.1 per 1,000 delivery hospitalizations-years to 144.8 per 1,000 postpartum hospitalizations-years). The incidence of ICU admission rose 68% among pregnancy-associated hospitalizations and for all examined subgroups, except abortion. Preeclampsia/eclampsia (23.3%) and obstetric hemorrhage (6.9%) were the most common maternal complications among ICU admissions. Four hundred fourteen women (0.3%) died, while 97.6% were discharged home. CONCLUSIONS This study documents the highest incidence of ICU utilization in obstetric patients in the US to date. The findings suggest low threshold for obstetric ICU admissions in the state and do not support comparative use of ICU utilization as surrogate measure for populations' burden of severe maternal morbidity and near-miss events. Nevertheless, the demonstrated tremendous heterogeneity in ICU utilization across examined subgroups identifies new high-risk groups of obstetric patients that would benefit from heightened clinician vigilance and timely ICU triage and care. Further studies are needed to inform reduction in avoidable variability in ICU utilization to both enhance maternal, fetal, and neonatal outcomes and to improve resource allocation.

Abstract
BACKGROUND/AIMS Depression is common in patients with end-stage renal disease (ESRD) on hemodialysis (HD). Although, depression is associated with mortality, the effect of depression on in-hospital outcomes has not been studied as yet. METHODS We analyzed the National Inpatient Sample for trends and outcomes of hospitalizations with depression in patients with ESRD. RESULTS The proportion of ESRD hospitalizations with depression doubled from 2005 to 2013 (5.01-11.78%). Hospitalized patients on HD with depression were younger (60.47 vs. 62.70 years, p < 0.0001), female (56.93 vs. 47.81%, p < 0.0001), white (44.92 vs. 34.01%, p < 0.0001), and had higher proportion of comorbidities. However, there was a statistically significant lower risk of mortality in HD patients within the top 5 reasons for admissions. CONCLUSION There were significant differences in demographics and comorbidities for hospitalized HD patients with depression. Depression was associated with an increased rate of adverse effects in discharged patients, and decreased in-hospital mortality.

Abstract
BACKGROUND The future of neuroendovascular treatment for intracranial atherosclerotic disease (ICAD) has been debated since the results of SAMMPRIS reflected poor outcomes following endovascular therapy. There is currently a large spectrum of current management strategies. We compared historical outcomes of patients with ICAD and stroke that were treated with angioplasty-alone versus stent placement. METHODS We extracted a population from the Nationwide Inpatient Sample (NIS) (2005-2011) and the National Inpatient Sample (NIS) (2012) composed of patients with ICAD and infarction that were admitted nonelectively and received endovascular revascularization. Patients treated with thrombectomy or thrombolysis were excluded. Categorical variables were compared with Chi-squared tests. Binary logistic regression was performed to evaluate mortality while controlling for age, sex, severity, and comorbidities. RESULTS About 2059 admissions met our criteria. A majority were treated via stent placement (71%). Angioplasty-alone had significantly higher mortality (17.6% vs. 8.4%, P<0.001), but no difference in iatrogenic stroke rate (3.4% vs. 3.6%, P=0.826), compared to stent placement. The adjusted odds ratio of mortality for stented patients was 0.536 (95% CI: 0.381-0.753, P<0.001) in comparison to patients treated with angioplasty alone. CONCLUSIONS This study found the risk of mortality to be elevated following angioplasty alone in comparison to revascularization with stent placement, without a corresponding significant difference in iatrogenic stroke rate. This may represent selection bias due to patient characteristics not defined in the database, but it also may indicate that patients with ICAD and acute stroke have increased odds of stenosis that is refractory to angioplasty alone and have a high risk of mortality without revascularization.

Abstract
BACKGROUND AND AIMS Cirrhosis affects 5.5 million patients with estimated costs of US$4 billion. Previous studies about dialysis requiring acute kidney injury (AKI-D) in decompensated cirrhosis (DC) are from a single center/year. We aimed to describe national trends of incidence and impact of AKI-D in DC hospitalizations. METHODS We extracted our cohort from the Nationwide Inpatient Sample (NIS) from 2006-2012. We identified hospitalizations with DC and AKI-D by validated ICD9 codes. We analyzed temporal changes in DC hospitalizations complicated by AKI-D and utilized multivariable logistic regression models to estimate AKI-D impact on hospital mortality. RESULTS We identified a total of 3,655,700 adult DC hospitalizations from 2006 to 2012 of which 78,015 (2.1 %) had AKI-D. The proportion with AKI-D increased from 1.5 % in 2006 to 2.23 % in 2012; it was stable between 2009 and 2012 despite an increase in absolute numbers from 6773 to 13,930. The overall hospital mortality was significantly higher in hospitalizations with AKI-D versus those without (40.87 vs. 6.96 %; p < 0.001). In an adjusted multivariable analysis, adjusted odds ratio for mortality was 2.17 (95 % CI 2.06-2.28; p < 0.01) with AKI-D, which was stable from 2006 to 2012. Changes in demographics and increases in acute/chronic comorbidities and procedures explained temporal changes in AKI-D. CONCLUSIONS Proportion of DC hospitalizations with AKI-D increased from 2006 to 2009, and although this was stable from 2009 to 2012, there was an increase in absolute cases. These results elucidate the burden of AKI-D on DC hospitalizations and excess associated mortality, as well as highlight the importance of prevention, early diagnosis and testing of novel interventions in this vulnerable population.

Abstract
Nontraumatic intracerebral hemorrhage (ICH) is associated with substantial morbidity and mortality. Do-not-resuscitate (DNR) orders are linked to poorer outcomes in patients with ICH, possibly due to less active management. Demographic, regional, and social factors, not related to ICH severity, have not been adequately looked at as significant predictors of DNR utilization. We reviewed the Healthcare Cost and Utilization Project's Nationwide Inpatient Sample (NIS) database in 2011 for adult ICH admissions and DNR status. We generated hierarchical 2-level multivariate regression models to estimate adjusted odds ratios. We analyzed 25 768 ICH hospitalizations, 18% of which (4620 hospitalizations) had DNR orders, corresponding to national estimates of 126 254 and 22 668, respectively. In multivariable regression, female gender, white or Hispanic/Latino ethnicity, no insurance coverage, and teaching hospitals were significantly associated with increased DNR utilization after adjusting for confounders. There was also significantly more interhospital variability in the lowest quartile of hospital volume. In conclusion, demographic factors and insurance status are significantly associated with increased DNR utilization, with more individual hospital variability in low-volume hospitals. The reasons for this are likely qualitative and linked to patient, provider, and hospital practices.
