An Epidemiological Evaluation Of The Impact Of Percutaneous Coronary Interventions On The Hospitalization Cost, Length Of Stay And Mortality Of Patients Hospitalized With Acute Coronary Syndromes.

Discharge Abstract Database and National Ambulatory Care Reporting System database. All acute care hospitalization discharge abstracts with either congestive heart failure (ICD-10 code I50.0) recorded as the most responsible diagnosis (MRDx) or contributing diagnosis amongst patients aged ≥ 18 were included in the study. Abstracts with a CHF MRDx were categorized in the CHF group. The remaining abstracts were categorized into either the cardiovascular group (circulatory system disease MRDx (ICD-10 I00 – I99), excluding CHF) or non-cardiovascular group (non-circulatory system disease MRDx). Discharge abstracts with missing demographics, or absent without leave or against medical advice discharge status were excluded. Results: 156,847; 66,056; and 127,847 CHF, cardiovascular, and non-cardiovascular group discharge abstracts were included, respectively, of which 10%, 13% and 21% of the respective group abstracts resulted in death. The national mean hospitalization visit cost was $10,123; $20,890; and $21,283 for the CHF, cardiovascular, and non-cardiovascular groups respectively. For each CHF, cardiovascular, and non-cardiovascular group, a survival outcome incurred a lower national mean hospitalization visit cost at $9,222; $19,899; and $19,036 whereas a death outcome incurred a high national mean hospitalization visit cost at $18,087; $27,642; and $29,887, respectively. ConClusions: Cardiovascular and non-cardiovascular hospitalizations result in higher mean hospitalization costs than those with a CHF MRDx. An opportunity exists for interventions reducing the number of any CHF related hospitalization to ease the burden on healthcare.
