Hydrocortisone administration was associated with improved survival in Japanese patients with cardiac arrest.

ABSTRACT: There are few reports on hydrocortisone administration after cardiac arrest, and those that have been published included few subjects. This study aimed to evaluate the effect of hydrocortisone administration on the outcomes of patients who experienced cardiac arrest. We investigated the survival discharge rates and the length of hospital stay from cardiac arrest to discharge, stratified by use of hydrocortisone, using a Japanese health-insurance claims dataset that covers approximately 2% of the Japanese population. The study included the data of 2233 subjects who experienced either in-hospital or out-of-hospital cardiac arrest between January 2005 and May 2014. These patients were divided into two groups, based on the administration of hydrocortisone. We adjusted the baseline characteristics, medical treatment, and drug administration data of the two groups using propensity scores obtained via the inverse probability of treatment weighted method. The hydrocortisone group had a significantly higher survival discharge rate (13/61 [21.1%] vs. 240/2172 [11.0%], adjusted odds ratio: 4.2, 95% CI: 1.60-10.98, p?=?0.004). In addition, the administration of hydrocortisone was independent predictor of survival to discharge (hazard ratio: 4.6, p?

Project description:BACKGROUND:TTR (transthyretin) cardiac amyloidosis is caused by dissociation of TTR into monomers, which misassemble into amyloid fibrils. TTR stabilizers act at the dimer-dimer interface to prevent dissociation. We investigated differences in survival among patients with TTR cardiac amyloidosis on stabilizer medications compared with those not on stabilizers. METHODS AND RESULTS:A retrospective study of patients with TTR cardiac amyloidosis presenting to a single center was conducted. Baseline characteristics were compared between those treated with stabilizers and those not treated with stabilizers. Cox proportional hazards modeling assessed for univariate predictors of the composite outcome of death or orthotopic heart transplant (OHT). Multivariable Cox proportional hazards assessed whether stabilizer treatment was independently associated with improved death or OHT after controlling for significant univariate predictors. One hundred twenty patients (mean age, 75±8, 88% male) were included: 29 patients who received stabilizers and 91 patients who did not. Stabilizer use was associated with a lower risk of the combined end point of death or OHT (hazard ratio, 0.32; 95% confidence interval, 0.18-0.58; P<0.0001). Subjects treated with stabilizers were more likely to be of White race (93% versus 55%; P<0.001), classified as New York Heart Association classes I and II (79% versus 38%; P=0.002), less likely to have a mutation (10% versus 36%; P=0.010), have lower troponin I (median 0.06 versus 0.12 ng/mL; P=0.002), and higher left ventricular ejection fraction (49% versus 40%; P=0.011), suggesting earlier stage of disease. In multivariable Cox analysis, the association between stabilizer and death or OHT persisted when adjusted for all noncollinear univariate predictors with P<0.05 (hazard ratio, 0.37; 95% confidence interval, 0.19-0.75; P=0.003). CONCLUSIONS:TTR stabilizers are associated with decreased death and OHT in TTR cardiac amyloidosis. These results need to be confirmed by ongoing randomized clinical trials.

Project description:National efforts to measure hospital performance in treating cardiac arrest have focused on case survival, with the hope of improving survival after cardiac arrest. However, it is plausible that hospitals with high case-survival rates do a poor job of preventing cardiac arrests in the first place.To describe the association between inpatient cardiac arrest incidence and survival rates.Within a large, national registry, we identified hospitals with at least 50 adult in-hospital cardiac arrest cases between January 1, 2000, and November 30, 2009. We used multivariable hierarchical regression to evaluate the correlation between a hospital's cardiac arrest incidence rate and its case-survival rate after adjusting for patient and hospital characteristics.The correlation between a hospital's incidence rate and case-survival rate for cardiac arrest.Of 102,153 cases at 358 hospitals, the median hospital cardiac arrest incidence rate was 4.02 per 1000 admissions (interquartile range, 2.95-5.65 per 1000 admissions), and the median hospital case-survival rate was 18.8% (interquartile range, 14.5%-22.6%). In crude analyses, hospitals with higher case-survival rates also had lower cardiac arrest incidence (r, -0.16; P = .003). This relationship persisted after adjusting for patient characteristics (r, -0.15; P = .004). After adjusting for potential mediators of this relationship (ie, hospital characteristics), the relationship between incidence and case survival was attenuated (r, -0.07; P = .18). The one modifiable hospital factor that most attenuated this relationship was a hospital's nurse-to-bed ratio (r, -0.12; P = .03).Hospitals with exceptional rates of survival for in-hospital cardiac arrest are also better at preventing cardiac arrests, even after adjusting for patient case mix. This relationship is partially mediated by measured hospital attributes. Performance measures focused on case-survival rates seem an appropriate first step in quality measurement for in-hospital cardiac arrest.
