Abstract
Abstract
Background
Cardiac arrest (CA) is a lethal condition with high public health burden and grave long-term implications. We aimed to evaluate the rate and predictors of readmission after CA
Methods
We used the Nationwide Readmission Database 2014 to determine patient with index admission CA by using relevant ICD-9 codes. We excluded patients <18 years and admissions in October, November, and December to allow 90 days readmission follow up. We evaluated rates and causes of 30 and 90 days readmission. We investigated disposition options for CA survivors and rates of readmissions. Multivariable analysis was done for relevant variables to demonstrated predictors of readmission.
Results
A total cohort of 71,780 patients suffered CA and survived to hospital discharge. Mean age was 63.9±15 years and 61.3% were males. Mean length of stay was 14.2±18.3 days, primary payer was Medicare 58%, 42.2% were discharged home, 33% to skilled nursing/intermediate care facility, 18.5% to home with home health services, 5% to short term hospital, and 0.8% left against medical advice (AMA). All-cause 30 and 90 days readmission rates were 18% and 28.9%, respectively. According to each disposition group 30/90 days readmission rates were; home 13.6/23%, facility 22/35.7%, home health 21/31.9%, short term hospital 16.8/24.1%, and 33.7/42.4% left AMA. The most common causes of readmission at 30 and 90 days were congestive heart failure and infection (11% each). CA on readmission was 1.5% at 30 and 90 days. The most common predictors of readmission were CHF odds ratio (OR) 1.3, (95% CI: 1.3–1.4; P<0.001), renal failure OR 1.7, (95% CI: 1.7–1.8; P<0.001), chronic lung disease OR 1.3, (95% CI: 1.2–1.; P<0.001), and depression OR 1.1 (95% CI: 1.1–1.2; P<0.001).
Conclusion
Readmissions are common at 30 and 90 days in CA survivors and are associated with high cost. CHF and infection are the most common causes of 30 and 90-day readmission, while renal failure is the strongest predictor of readmission after adjusting for unbalanced covariates. Discharge to home was the most common disposition, and had the lowest rate for readmission. Leaving AMA had the highest rate of readmission.
