Project description:There are limited data on the epidemiology and timing of in-hospital death (IHD) in patients with acute myocardial infarction-cardiogenic shock (AMI-CS). Adult admissions with AMI-CS with IHDs were identified using the National Inpatient Sample (2000-2016) and were classified as early (≤2 days), mid-term (3-7 days), and late (>7 days). Inter-hospital transfers and those with do-not-resuscitate statuses were excluded. The outcomes of interest included the epidemiology, temporal trends and predictors for IHD timing. IHD was noted in 113,349 AMI-CS admissions (median time to IHD 3 (interquartile range 1-7) days), with early, mid-term and late IHD in 44%, 32% and 24%, respectively. Compared to the mid-term and late groups, the early IHD group had higher rates of ST-segment-elevation AMI-CS (74%, 63%, 60%) and cardiac arrest (37%, 33%, 29%), but lower rates of acute organ failure (68%, 79%, 89%), use of coronary angiography (45%, 56%, 67%), percutaneous coronary intervention (33%, 36%, 42%), and mechanical circulatory support (31%, 39%, 50%) (all p < 0.001). There was a temporal increase in the early (adjusted odds ratio (aOR) for 2016 vs. 2000 2.50 (95% confidence interval (CI) 2.22-2.78)) and a decrease in mid-term (aOR 0.75 (95% CI 0.71-0.79)) and late (aOR 0.34 (95% CI 0.31-0.37)) IHD. ST-segment-elevation AMI-CS and cardiac arrest were associated with the increased risk of early IHD, whereas advanced comorbidity and acute organ failure were associated with late IHD. Early IHD after AMI-CS has increased between 2000 and 2016. The populations with early vs. late IHD were systematically different.

Project description:Reports that septic shock incidence is rising and mortality rates declining may be confounded by improving recognition of sepsis and changing coding practices. We compared trends in septic shock incidence and mortality in academic hospitals using clinical vs claims data.We identified all patients with concurrent blood cultures, antibiotics, and vasopressors for ? two consecutive days, and all patients with International Classification of Diseases, 9th edition (ICD-9) codes for septic shock, at 27 academic hospitals from 2005 to 2014. We compared annual incidence and mortality trends. We reviewed 967 records from three hospitals to estimate the accuracy of each method.Of 6.5 million adult hospitalizations, 99,312 (1.5%) were flagged by clinical criteria, 82,350 (1.3%) by ICD-9 codes, and 44,651 (0.7%) by both. Sensitivity for clinical criteria was higher than claims (74.8% vs 48.3%; P < .01), whereas positive predictive value was comparable (83% vs 89%; P = .23). Septic shock incidence, based on clinical criteria, rose from 12.8 to 18.6 cases per 1,000 hospitalizations (average, 4.9% increase/y; 95% CI, 4.0%-5.9%), while mortality declined from 54.9% to 50.7% (average, 0.6% decline/y; 95% CI, 0.4%-0.8%). In contrast, septic shock incidence, based on ICD-9 codes, increased from 6.7 to 19.3 per 1,000 hospitalizations (19.8% increase/y; 95% CI, 16.6%-20.9%), while mortality decreased from 48.3% to 39.3% (1.2% decline/y; 95% CI, 0.9%-1.6%).A clinical surveillance definition based on concurrent vasopressors, blood cultures, and antibiotics accurately identifies septic shock hospitalizations and suggests that the incidence of patients receiving treatment for septic shock has risen and mortality rates have fallen, but less dramatically than estimated on the basis of ICD-9 codes.

Project description:Takotsubo (or stress induced) cardiomyopathy is characterized by transient left ventricular systolic dysfunction. Recent trends in patient volume, characteristics, and outcomes in the United States are unknown.Using 2007-2012 National Inpatient Sample data, we identified 22,005 adults (?18 years) with a primary and 31,942 adults with a secondary discharge diagnosis of takotsubo cardiomyopathy (International Classification of Diseases, Ninth Revision, code 429.83) who underwent diagnostic coronary angiography.During 2007 to 2012, the incidence of takotsubo cardiomyopathy increased over 3-fold: 52/million discharges in 2007 to 178/million in 2012 (P < .001). We found a temporal increase in the prevalence of cardiac arrest, cardiogenic shock, cardiovascular risk factors (diabetes, hypertension), and psychiatric disorders (P trend < .0001 for all). In-hospital mortality was 1.1% and remained unchanged over this period (P = .22). Compared to the primary diagnosis group, mortality in the secondary diagnosis group was higher (1.1% vs 3.2%) and was associated with higher incidence of cardiogenic shock, cardiac arrest, and respiratory failure. Men represent 8% of patients in the primary diagnosis group and 12% in the secondary group. In both groups, men had a higher incidence of shock, cardiac arrest, and respiratory failure. Although their mortality was higher than women in the primary group (3.0% vs 0.9%, adjusted odds ratio 3.85, 1.74-8.51), it was comparable in the secondary group (4.8% vs 3.0%).We found a marked increase in the hospitalization for takotsubo cardiomyopathy in the United States in recent years, suggesting higher incidence than prior reports. Although outcomes have remained favorable, there is an increasing burden of cardiovascular and psychiatric disorders in this population with growing cost of care. Risk of mortality is higher in men and in patients with underlying critical illness. The excess mortality in these groups appears to be mediated by greater severity of disease.

Project description:ObjectiveTo evaluate national trends in hospitalizations and in-hospital mortality in rheumatoid arthritis (RA).MethodsNational Inpatient Sample from 2000-2014 and United States Census data were used to study temporal trends in adult RA hospitalizations, reasons for hospitalizations, and in-hospital mortality.ResultsThe data represented 183 983 hospitalizations with a primary diagnosis of RA. The annual rates of hospitalization for the primary diagnosis of RA decreased from 76.54 admissions per 1 million in 2000 to 29.96 per 1 million in 2014 (P trend < 0.0001). The hospital mortality rate declined from 0.70% to 0.41% (P trend < 0.0001) in this group. With a primary or nonprimary diagnosis of RA, the mortality rate ranged between 1.95 and 2.87 (P trend 0.08). For a nonprimary diagnosis of RA, we noted that the proportion of hospitalizations with a diagnosis of myocardial infarction (6.4% in 2000 to 4.6% in 2014; P < 0.001) significantly decreased, but the absolute number of hospitalizations significantly increased. In contrast, the proportion and the absolute number of hospitalizations with any diagnosis of sepsis, congestive heart failure, lung disease, and urinary tract infection increased significantly. We also noted a significant increase in the actual rate and proportions for hospitalizations for hip and knee arthroplasty. Among in-hospital deaths when RA was a nonprimary diagnosis, the most common primary diagnosis was pneumonia (12.5 %) in 2000, whereas sepsis accounted for the most deaths in 2014 (31.4%).ConclusionWe observed that hospitalization rates and in-hospital mortality rates in patients with RA have changed significantly over the past 15 years.

Project description:AimThe management of cardiogenic shock remains a clinical challenge even in well-developed healthcare systems, best illustrated by its high mortality despite numerous innovative proposals for management. The aim of this study was to describe temporal trends in incidence, causes, use of mechanical circulatory support, and mortality in cardiogenic shock in Germany.Methods and resultsData on all cardiogenic shock patients treated in German hospitals between 2005 and 2017 were obtained from the Federal Bureau of Statistics. The data set comprised 441 696 patients with cardiogenic shock, mean age 71 (±13.8) years, 171 383 (39%) female patients. Incidence rates increased from 33.1/100 000 population in 2005 (27 246 cases) to 51.7/100 000 population in 2017 (42 779 cases). Acute myocardial infarction was the most common cause of cardiogenic shock in 2005-07 (43 422 of 82 037 cases, 52.9%), but the proportion of cases caused by it decreased until 2014-17 (73 274 of 165 873 cases, 44.2%). Over time, intra-aortic balloon pump (2005: 5104; 2017: 973 cases) was used less frequently, whereas use of extracorporeal-membrane-oxygenation (2007: 35; 2017: 2414 cases) and percutaneous left ventricular assist devices (2005: 27; 2017: 1323 cases) increased. Mortality remained high at around 60% without relevant temporal trends in patients without acute myocardial infarction and slightly decreased in patients with acute myocardial infarction.ConclusionsIn this large, nation-wide study, annual incidence of cardiogenic shock was growing, its causes were changing, and mortality was high despite a shift towards use of novel mechanical circulatory support devices. This highlights the need to address the evidence gap in this field, in particular for cardiogenic shock caused by diseases other than acute myocardial infarction.

Project description:BackgroundMeningioma incidence was reported to have risen substantially in the United States during the first decade of the 21st century. There are few reports about subsequent incidence trends. This study provides updated data to investigate trends in meningioma incidence by demographic and tumor characteristics at diagnosis in the United states from 2004 to 2015.MethodsTrends in meningioma incidence were analyzed using data from the Surveillance, Epidemiology, and End Results-18 (SEER-18) registry database of the National Cancer Institute. The joinpoint program was used to calculate annual percent change (APC) in incidence rates.ResultsThe overall incidence of meningioma increased by 4.6% (95% CI, 3.4-5.9) annually in 2004-2009, but remained stable from 2009 to 2015 (APC, 0; 95% CI, -0.8 to 0.8). Females (10.66 per 100 000 person-years) and blacks (9.52 per 100 000 person-years) had significant predominance in meningioma incidence. Incidence in many subgroups increased significantly up to 2009 and then remained stable until 2015. However, meningioma incidence in young and middle-aged people increased significantly throughout the entire time period from 2004 to 2015 (APC: 3.6% for <20-year-olds; 2.5% for 20-39-year-olds; 1.8% for 40-59-year-olds). The incidence of WHO II meningioma increased during 2011-2015 (APC = 5.4%), while the incidence of WHO III meningioma decreased during 2004-2015 (APC = -5.6%).ConclusionIn this study, the incidence of meningioma was found to be stable in recent years. Possible reasons for this finding include changes in population characteristics, the widespread use of diagnostic techniques, and changes in tumor classification and risk factors in the US population.

Project description:Cardiogenic shock (CS) carries high mortality and morbidity. Early revascularization is an important strategy in management of these patients. We sought to determine the outcomes and predictors of revascularization among patients with CS. Patients with CS and acute myocardial infarction were identified using the National Inpatient Sample (NIS) data from January 2002 to December 2014 using the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes. Subsequently, patients who underwent revascularization were then selected. A total of 118,618 patients with CS were identified. Out of these, about 55,735 (47%) patients underwent revascularization. Mean age of patients who underwent revascularization was lower when compared with patients not who underwent revascularization (66.40 vs 72.24 years, p < 0.01). Patients who underwent revascularization had lower mortality when compared with patients not who underwent revascularization (25.1% vs 52.2%, p < 0.01). Extracorporeal membrane oxygenation and mechanical circulatory support devices were often utilized more in patients who underwent revascularization. Overall, we found modest increased trend of revascularization over our study years with decline in mortality. Female gender, weekend admission, drug abuse, pulmonary hypertension, anemia, renal failure, neurological disorders, malignancy were associated with lower odds of revascularization. In conclusion, in this large nationally represented US population sample of CS patients, we found revascularization rate of about 47% with improvement in overall mortality over our study years.

Project description:ObjectivesMixed cardiogenic-septic shock is common and associated with high mortality. There are limited contemporary data on concomitant sepsis in acute myocardial infarction complicated by cardiogenic shock (AMI-CS).DesignObservational study.SettingTwenty percent stratified sample of all community hospitals (2000-2014) in the United States.ParticipantsAdults (> 18 yr) with AMI-CS with and without concomitant sepsis.InterventionsNone.Measurements and main resultsOutcomes of interest included inhospital mortality, development of noncardiac organ failure, complications, utilization of guideline-directed procedures, length of stay, and hospitalization costs. Over 15 years, 444,253 AMI-CS admissions were identified, of which 27,057 (6%) included sepsis. The sepsis cohort had more comorbidities and had higher rates of noncardiac multiple organ failure (92% vs 69%) (all p < 0.001). In 2014, compared with 2000, the prevalence of sepsis increased from 0.5% versus 11.5% with an adjusted odds ratio (aOR) 11.71 (95% CI, 9.7-14.0) in ST-segment elevation myocardial infarction and 24.6 (CI, 16.4-36.7) (all p < 0.001) in non-ST segment elevation myocardial infarction. The sepsis cohort received fewer cardiac interventions (coronary angiography [65% vs 68%], percutaneous coronary intervention [43% vs 48%]) and had greater use of mechanical circulatory support (48% vs 45%) and noncardiac support (invasive mechanical ventilation [65% vs 41%] and acute hemodialysis [12% vs 3%]) (p < 0.001). The sepsis cohort had higher inhospital mortality (44.3% vs 38.1%; aOR, 1.21; 95% CI, 1.18-1.25; p < 0.001), longer length of stay (14.0 d [7-24 d] vs 7.0 d [3-12 d]), greater hospitalization costs (×1,000 U.S. dollars) ($176.0 [$85-$331] vs $77.0 [$36-$147]), fewer discharges to home (22% vs 44%) and more discharges to skilled nursing facilities (51% vs 28%) (all p < 0.001).ConclusionsIn AMI-CS, concomitant sepsis is associated with higher mortality and morbidity highlighting the need for early recognition and integrated management of mixed shock.

Project description:BackgroundWith a growing emphasis on value of care, understanding factors associated with rising healthcare costs is increasingly important. In this national study, we evaluated the degree of center-level variation in the cost of spinal fusion.MethodsAll adults undergoing elective spinal fusion were identified in the 2016 to 2020 National Inpatient Sample. Multilevel mixed-effect models were used to rank hospitals based on risk-adjusted costs. The interclass coefficient (ICC) was utilized to tabulate the amount of variation attributable to hospital-level characteristics. The association of high cost-hospital (HCH) status with in-hospital mortality, perioperative complications, and overall resource utilization was analyzed. Predictors of increased costs were secondarily explored.ResultsAn estimated 1,541,740 patients underwent spinal fusion, and HCH performed an average of 9.5% of annual cases. HCH were more likely to be small (36.8 vs 30.5%, p<0.001), rural (10.1 vs 8.8%, p<0.001), and located in the Western geographic region (49.9 vs 16.7%, p<0.001). The ICC demonstrated 32% of variation in cost was attributable to the hospital, independent of patient-level characteristics. Patients who received a spinal fusion at a HCH faced similar odds of mortality (0.74 [0.48-1.15], p = 0.18) and perioperative complications (1.04 [0.93-1.16], p = 0.52), but increased odds of non-home discharge (1.30 [1.17-1.45], p<0.001) and prolonged length of stay (β 0.34 [0.26-0.42] days, p = 0.18). Patient factors such as gender, race, and income quartile significantly impacted costs.ConclusionThe present analysis identified 32% of the observed variation to be attributable to hospital-level characteristics. HCH status was not associated with increased mortality or perioperative complications.

Project description:The disease risks from cigarette smoking increased in the United States over most of the 20th century, first among male smokers and later among female smokers. Whether these risks have continued to increase during the past 20 years is unclear.We measured temporal trends in mortality across three time periods (1959-1965, 1982-1988, and 2000-2010), comparing absolute and relative risks according to sex and self-reported smoking status in two historical cohort studies and in five pooled contemporary cohort studies, among participants who became 55 years of age or older during follow-up.For women who were current smokers, as compared with women who had never smoked, the relative risks of death from lung cancer were 2.73, 12.65, and 25.66 in the 1960s, 1980s, and contemporary cohorts, respectively; corresponding relative risks for male current smokers, as compared with men who had never smoked, were 12.22, 23.81, and 24.97. In the contemporary cohorts, male and female current smokers also had similar relative risks for death from chronic obstructive pulmonary disease (COPD) (25.61 for men and 22.35 for women), ischemic heart disease (2.50 for men and 2.86 for women), any type of stroke (1.92 for men and 2.10 for women), and all causes combined (2.80 for men and 2.76 for women). Mortality from COPD among male smokers continued to increase in the contemporary cohorts in nearly all the age groups represented in the study and within each stratum of duration and intensity of smoking. Among men 55 to 74 years of age and women 60 to 74 years of age, all-cause mortality was at least three times as high among current smokers as among those who had never smoked. Smoking cessation at any age dramatically reduced death rates.The risk of death from cigarette smoking continues to increase among women and the increased risks are now nearly identical for men and women, as compared with persons who have never smoked. Among men, the risks associated with smoking have plateaued at the high levels seen in the 1980s, except for a continuing, unexplained increase in mortality from COPD.
