Background: Understanding trends in pneumonia-associated hospitalizations can help to quantify the burden of disease and identify risk conditions and at-risk populations. This study evaluated characteristics of hospitalizations due to pneumonia that occurred in Italy in a 10-year period from 2010 to 2019. Methods: All hospitalizations with a principal or secondary diagnosis of pneumonia over the 10-year period were included, which were identified by hospital discharges for all-cause pneumonia and pneumococcal pneumonia in the anonymized hospital discharge database of the Italian Health Ministry. Results: A total of 2,481,213 patients were hospitalized for pneumonia between 2010 and 2019; patients aged 75–86 years accounted for 30.1% of hospitalizations. Most hospitalizations (88.1%) had an unspecified pneumonia discharge code. In-hospital death was recorded in 13.0% of cases. The cumulative cost for pneumonia hospitalizations of the 10-year period were EUR 11,303,461,591. Over the observation period, the incidence rate for hospitalized all-cause pneumonia in any ages increased from 100 per 100,000 in 2010 to over 160 cases per 100,000 per year in 2019 (p < 0.001). Overall, there was a significant increase in annual percent changes in hospitalization rates (+3.47 per year), in-hospital death (+4.6% per year), and costs (+3.95% per year) over the 10-year period. Conclusions: Our analysis suggests that hospitalizations for pneumonia are increasing over time in almost all age groups, especially in the elderly. Given the substantial burden of pneumonia in terms of mortality, healthcare resources, and economic costs, greater public health efforts should thus be made to promote vaccinations against influenza and pneumococcus, particularly in high-risk groups.

Background: Respiratory syncytial virus (RSV) affects 60–80% of children below 1 year and it’s the first cause of acute bronchiolitis. The aim of this study was to assess the trend and characteristics of hospitalizations for RSV infections in Italy. Methods: This is a retrospective study based on the Italian Hospital Discharge Record (HDR) database. We analysed HDRs from June 2015 to May 2019, considering two groups of infants: Group 1 had a confirmed diagnosis of RSV; Group 2 had a diagnosis of acute bronchiolitis not RSV-coded. Results: There were 67,746 overall hospitalizations (40.1% Group 1, and 59.9% Group 2). Hospitalization rate increased for Group 1 from 125 to 178 per 10,000 infants (+ 42.4%), and for Group 2 from 210 to 234 per 10,000 (+ 11.4%). The mean hospitalization length was 6.3 days in Group 1, longer than Group 2 (+ 1.0 day). A further analysis revealed that infants with heart disease or born premature had longer mean hospital stay compared to infants without risk factors (10.7 days versus 6.1 days, p < 0.0001; 34.0 days versus 6.1 days, p < 0.0001, respectively). Group 1 required more critical care (oxygen therapy and/or mechanical ventilation) than Group 2. We found that, in proportion to hospital admissions in pediatric and general hospitals, RSV was more frequently diagnosed in the first ones. The mean hospitalization cost increased for Group 1 (from € 2,483 to € 2,617) and Group 2 (from € 2,007 to € 2,180). Conclusions: Our results confirmed that RSV pulmonary disease in infants is seasonal and often requires hospitalization. Our study suggested that RSV is responsible for an increasing hospitalization rate and related costs during the study period.

Objective: Our study's objective was to assess the incidence trends and healthcare resource utilization of hospitalizations for Tick-Borne Encephalitis (TBE) and associated costs in Italy in order to improve public awareness and preventive measures. Methods: This retrospective observational study was based on the Italian Ministry of Health's Hospital Discharge Record (HDR) database. Data were gathered across Italy from 2015 to 2019, selecting hospitalizations with ICD-9 code 063 related to TBE, both in primary and secondary diagnoses. For each year, we collected the following variables: number of hospitalizations, hospitalization rate, mortality rate, mean length of hospital stay, hospital ward, and cost of hospitalization. Results: There were a total of 237 hospitalizations from 2015 to 2019; 62 % of those were male. The lowest number of TBE hospitalizations was in 2015 (21 cases, corresponding to 0.35 per million inhabitants), the highest in 2019 (64 cases, 1.04 per million inhabitants). The summer months saw a greater than average number of hospitalizations. For the years analyzed, the cumulative number of cases peaked in June (54 cases), July (46 cases), and August (35 cases). There were only two deaths registered in our study sample. TBE cases were mostly localized in the North-Eastern regions of Italy. TBE incidence during the study period in the most affected areas were: Autonomous Province of Trento, ranging from 11.2 to 42.3 per million inhabitants, Autonomous Province of South Tyrol, from 0 to 21.1 per million inhabitants, and Veneto Region, from 2.6 to 4.5 per million inhabitants. In the study period, the average length of hospital stay was largely stable ranging from 10.6 days to 12.8 days, with related costs ranging from 5,813.7 € to 7,352.5 €. Conclusions: According to our data, the majority of TBE hospitalizations occur in North-East Italy with an increasing trend over the analyzed period. Even though Italy has fewer TBE cases than other neighboring European countries, the health and economic impact can be high in the affected areas.

Background: Chronic ischemic cardiovascular disease (CICD) is a common cardiovascular disease and a frequent cause of hospitalization, with significant differences between men and women. It is also an important comorbidity, affecting hospitalization length and mortality. The purpose of this paper is to investigate the clinical and economic impact of CICD on hospital admissions of non-surgical patients. Methods: To conduct the study, hospital discharge data (SDO) from each public and private hospital facility regularly sent by the regions to the Ministry of Health were analyzed, focusing on internal medicine, cardiology, and geriatrics departments’ 2019 discharged data coming from all Italian hospitals. Data were stratified according to age, gender, hospital charge ward, and costs. Results: The typical CICD patient is elderly (average age 80 years) and stays longer (+10.5 days) compared to the average one. They are also typically chronic patients with many comorbidities (respiratory and renal failure, as well as atrial fibrillation) in geriatrics and internal medicine departments, while in the cardiology departments, atrial fibrillation and outcomes of acute cardiovascular events predominate. Conclusions: CICD is a condition that leads to more hospitalizations in internal medicine departments than in cardiology and geriatrics departments and generates an average hospitalization value in line with the average one in internal medicine and geriatrics departments. In cardiology, the average value level is higher than the department average. Gender differences were found in cardiology departments; this data could suggest that the existing guidelines are affected by studies carried out mainly on males which lead to fewer recommendations for interventional procedures on females.

Background/Objectives: Chronic ischemic cardiovascular disease (CICD) a common cardiovascular diseases and a frequent cause of hospitalization, with significant differences between men and women. It is also an important comorbidity, affecting hospitalization length and mortality. The purpose of this paper is to investigate clinical and economic impact of chronic ischemic cardiovascular disease on hospital admissions of non-surgical patients. Methods: all Internal Medicine, Cardiology, and Geriatrics admissions in Italy during year 2023 have been considered. to assess the impact of typical comorbidities in elderly patients and to better understand how users diversify across the three specialties and whether the differences are significant between males and females. Results: The typical CICD patient is elderly (average age 80y) and stays longer (+10.5 days) compared to the average one. They are also typically chronic patients with many comorbidities (respiratory and renal failure, as well as atrial fibrillation) in Geriatrics and Internal Medicine Departments, while in the Cardiology Departments atrial fibrillation and outcomes of acute cardiovascular events predominate. Conclusions: CICD is a condition that leads to more hospitalizations in Internal Medicine Departments than in Cardiology and Geriatrics Departments and generates an average hospitalization value in line with the average one in Internal Medicine and Geriatrics Departments. In Cardiology the average value level is higher also than the Department average. Gender differences were found in In Cardiology Departments; this data could suggest that the existing Guidelines are affected by studies carried out mainly on males which lead to fewer recommendations for interventional procedures on females.
