P122 | Coronary heart disease: hospital impact and focus in Internal Medicine department

Background: Coronary heart disease (CHD) is one of the most common cardiovascular diseases causing hospitalization. Important comorbidity, it increase length of hospitalization and mortality. The research investigate CHD clinical and economic impact in hospital admissions.Methods: Prospective, observational study realized processing data of Italian hospital discharge records (SDO) provided by the Ministry of Health (year 2019). Extraction of SDO aggregated and anonymized data from the Internal Medicine(IM), Geriatrics and Cardiology departments, considering whether the CHD was cause of hospitalization or comorbidity. Were considered: number of hospitalizations, impact on department activity, average length of stay, average age at the time of hospitalization, sex, comorbidities.Results: CHD represents 15% (157,000 pts) of hospitalizations in IM, 19.4% (25,000 pts) in Geriatrics and 25% (118,000 pts) in Cardiology; it is the main diagnosis in 30%, 30% and 50% of hospitalizations respectively. The average hospital stay is 1 day (SD +- 4) longer than that of the ward, and more than 1 day as a comorbidity. Average age is 2 years greater than the department average (SD+-2). In 10% of cases atrial fibrillation is the most common comorbidity. Average cost of hospitalization is in line in the IM and Geriatrics departments (€3500), while it is €500 higher in Cardiology(€5000).Conclusions: CHD affects between 15 and 25% in terms of both the number of hospitalizations and the economic value of the activity. The value of hospitalizations amounts to €1.3 billion, over 40% (€555 million) in IM.
