Prevalence, Causes, and Predictors of 30-Day Readmissions Following Hospitalization With Acute Myocardial Infarction Complicated By Cardiogenic Shock: Findings From the 2013-2014 National Readmissions Database.
Prior studies have shown that survivors of acute myocardial infarction (AMI) complicated by cardiogenic shock are likely to have increased risk of readmissions in the early post-discharge period. However, the contemporary prevalence, reasons, and predictors of 30-day readmissions are not well known.
Hospitalizations for a primary diagnosis of AMI complicated by cardiogenic shock, and discharged alive, were identified in the 2013 and 2014 Nationwide Readmissions Databases. Prevalence and reasons for 30-day unplanned readmissions were investigated. A hierarchical logistic regression model was used to identify independent predictors of 30-day readmissions. Among 1 116 933 patient hospitalizations with AMI, 39 807 (3.6%) had cardiogenic shock and were discharged alive. Their 30-day readmission rate was 18.6%, with a median time for readmission 10 days post discharge. Predictors of readmission included: non-ST-segment elevation myocardial infarction, female sex, low-income status, nonprivate insurance, chronic renal failure, long-term ventricular assist device or intra-aortic balloon placement, and tachyarrhythmia. The majority of readmissions were attributable to cardiac-related causes (52%); heart failure being the most frequent cardiac cause (39% of all cardiac causes). Noncardiac-related readmissions included infections (14.9%), bleeding (5.3%), and respiratory causes (4.9%). The median cost per readmission was $9473 US dollars ($5037-20 199).
Among survivors of AMI complicated by cardiogenic shock who were discharged from hospital, almost 1 in 5 are readmitted at 30 days, mainly because of cardiac reasons such as heart failure and new AMI. The risk of readmission was associated with certain baseline patient/hospital characteristics.

Frequency of 30-day readmission and its causes after percutaneous coronary intervention in acute myocardial infarction complicated by cardiogenic shock.
Survival after percutaneous coronary intervention (PCI) in acute myocardial infarction complicated by cardiogenic shock (AMI-CS) has increased over the years. Short-term readmission rates in this high-risk population remain unknown.
We queried the United States (U.S.) Nationwide Readmission Database (NRD) from January 2010 to November 2014 using the International Classification of Diseases-Ninth edition, Clinical Modification (ICD-9 CM) codes to identify all patients ≥18 years readmitted within 30 days after surviving an index hospitalization for PCI in AMI-CS. Incidence, etiologies, and predictors of 30-day readmission were analyzed.
Among 46,435 patients who survived to discharge after PCI in AMI-CS, 9,020 (19.4%) were readmitted within 30 days. Median time to 30-day readmission was 11 days. Cardiac conditions were the most common causes of readmission (57.8%). Heart failure was the leading readmission diagnosis (24.8%). Private insurance including HMO and self-pay were predictive of lower 30-day readmission. Among other covariates, female sex, comorbidities such as heart failure, atrial fibrillation, in-hospital complications such as major bleeding, sepsis, respiratory complications, AKI requiring dialysis, utilization of mechanical circulatory support (IABP and ECMO) were independently predictive of 30-day readmission. Trend analysis showed decline in 30-day readmission rates from 21.9% in 2010 to 17.9% in 2014 (ptrend < 0.001).
In this large real-world database, one in five patients receiving PCI in AMI-CS was readmitted within 30 days after discharge. Cardiac conditions were the most common causes of readmission. Insurance type had significant influence on 30-day readmission.

Causes and Predictors of 30-Day Readmission in Patients With Acute Myocardial Infarction and Cardiogenic Shock.
Acute myocardial infarction (AMI) occurs as a result of irreversible damage to cardiac myocytes secondary to lack of blood supply. Cardiogenic shock complicating AMI has significant associated morbidity and mortality, and data on postdischarge outcomes are limited.
We derived the study cohort of patients with AMI and cardiogenic shock from the 2013 to 2014 Healthcare Cost and Utilization Project National Readmission Database. Incidence, predictors, and causes of 30-day readmissions were analyzed. From 43 212 index admissions for AMI with cardiogenic shock, 26 016 (60.2%) survived to discharge and 5277 (20.2% of survivors) patients were readmitted within 30 days. More than 50% of these readmissions occurred within first 10 days. Cardiac causes accounted for 42% of 30-day readmissions (heart failure 20.6%; acute coronary syndrome 11.6%). Among noncardiac causes, respiratory (11.4%), infectious (9.4%), medical or surgical care complications (6.3%), gastrointestinal/hepatobiliary (6.5%), and renal causes (4.8%) were most common. Length of stay ≥8 days (odds ratio [OR], 2.04; 95% confidence interval [CI], 1.70-2.44; P<0.01), acute deep venous thrombosis (OR, 1.26; 95% CI, 1.08-1.48; P<0.01), liver disease (OR, 1.25; 95% CI, 1.03-1.50; P=0.02), systemic thromboembolism (OR, 1.21; 95% CI, 1.02-1.44; P=0.02), peripheral vascular disease (OR, 1.16; 95% CI, 1.07-1.27; P<0.01), diabetes mellitus (OR, 1.16; 95% CI, 1.08-1.24; P<0.01), long-term ventricular assist device implantation (OR, 1.77; 95% CI, 1.23-2.55; P<0.01), intraaortic balloon pump use (OR, 1.10; 95% CI, 1.02-1.18; P<0.01), performance of coronary artery bypass grafting (OR, 0.85; 95% CI, 0.77-0.93; P<0.01), private insurance (OR, 0.72; 95% CI, 0.64-0.80; P<0.01), and discharge to home (OR, 0.85; 95% CI, 0.73-0.98; P=0.03) were among the independent predictors of 30-day readmission.
In-hospital mortality and 30-day readmission in cardiogenic shock complicating AMI are significantly elevated. Patients are readmitted mainly for noncardiac causes. Identification of high-risk factors may guide interventions to improve outcomes within this population.

Gender Impact on 30-Day Readmissions After Hospitalization With Acute Myocardial Infarction Complicated by Cardiogenic Shock (from the 2013 to 2014 National Readmissions Database).
Previous studies have suggested that women are more likely to have increased risk of readmissions after acute myocardial infarction (AMI); however, this difference has not been examined in the setting of AMI complicated by cardiogenic shock. Thus, we aimed to compare 30-day readmissions in women versus men initially admitted with AMI complicated with cardiogenic shock. In this observational study, we used the Nationwide Readmissions Databases years 2013 and 2014 to identify subjects who were initially hospitalized with a primary diagnosis of AMI complicated by cardiogenic shock, and discharged alive. The 30-day readmission rates between women and men were compared using a multivariate Cox regression model adjusting for variable co-morbidities, as well as a propensity-matched analysis. Of 1,116,933 patients who had AMI, 39,807 (3.6%) had cardiogenic shock and were discharged alive. The rates of in-hospital procedures such as percutaneous coronary intervention, coronary artery bypass grafting, and intra-aortic balloon placement were less frequent in women. Thirty-day readmissions were higher in women (20.7%) than in men (17.6%), after adjustment for various co-morbidities (hazards ratio 1.09, 95% confidence interval 1.00 to 1.19, p = 0.04), and in the propensity-matched analysis (hazards ratio 1.10, 95% confidence interval 1.01 to 1.21, p = 0.04). In conclusion, women are at a higher risk of 30-day readmissions after AMI complicated with cardiogenic shock.
