Economic impact of the use of rifaximin 550 mg twice daily for the treatment of overt hepatic encephalopathy in Italy

Daniela Paola Roggeri, Alessandro Roggeri ProCure Solutions, Nembro, Bergamo, Italy Purpose: Hepatic encephalopathy (HE) is associated with a reduced survival, an increased risk of hospitalization for recurrences, and a reduced health-related quality of life. The purpose of the present economic analysis was to evaluate the impact on the Italian National Health Service (INHS) expenditure of the treatment with rifaximin 550 mg twice daily (Tixteller®/Tixtar®) for the reduction of the recurrences of overt HE, with respect to the current treatment approach. Patients and methods: Costs associated with patients treated with rifaximin 550 mg twice daily were estimated considering the reduction in hospitalizations for HE recurrences revealed by registrative clinical trial (−50%) applied to the hospitalization rate (42.5%) emerging from an Italian observational real-world study; costs associated with patients not treated with rifaximin were estimated based on the hospitalization rate, resulting from the same Italian observational study. Sensitivity analyses considering possible different discount levels to INHS structures for rifaximin were performed. The INHS perspective for a period of 3 years was considered. Results: The treatment with rifaximin 550 mg twice daily, although increasing drug costs, is associated with a reduction in hospitalizations for HE recurrences that leads to an overall reduction of total costs charged to INHS, which could be estimated, based on the forecasted uptake of the treatment, at about €130,000 in the first year, reaching ~€260,000 in the third year. Considering a possible discount for rifaximin 550 mg to INHS structure of 20%, the total saving at the third year accounts for ~€3,000,000. Moreover, a relevant reduction in the number of hospitalizations and bed days is associated with rifaximin treatment. Conclusion: The treatment with rifaximin 550 mg twice daily, even if associated with an increase in drug expenditure, results in a reduction in total health care costs charged to INHS due to a reduction in hospitalizations for HE recurrences.

Inhalation errors due to device switch in patients with chronic obstructive pulmonary disease and asthma: critical health and economic issues

Alessandro Roggeri,1 Claudio Micheletto,2 Daniela Paola Roggeri1 1ProCure Solutions, Nembro, Bergamo, Italy, 2Respiratory Unit, Mater Salutis Hospital, Legnago, Verona, Italy Background: Different inhalation devices are characterized by different techniques of use. The untrained switching of device in chronic obstructive pulmonary disease (COPD) and asthma patients may be associated with inadequate inhalation technique and, consequently, could lead to a reduction in adherence to treatment and limit control of the disease. The aim of this analysis was to estimate the potential economic impact related to errors in inhalation in patients switching device without adequate training. Methods: An Italian real-practice study conducted in patients affected by COPD and asthma has shown an increase in health care resource consumption associated with misuse of inhalers. Particularly, significantly higher rates of hospitalizations, emergency room visits (ER), and pharmacological treatments (steroids and antimicrobials) were observed. In this analysis, those differences in resource consumption were monetized considering the Italian National Health Service (INHS) perspective. Results: Comparing a hypothetical cohort of 100 COPD patients with at least a critical error in inhalation vs 100 COPD patients without errors in inhalation, a yearly excess of 11.5 hospitalizations, 13 ER visits, 19.5 antimicrobial courses, and 47 corticosteroid courses for the first population were revealed. In the same way, considering 100 asthma patients with at least a critical error in inhalation vs 100 asthma patients without errors in inhalation, the first population is associated with a yearly excess of 19 hospitalizations, 26.5 ER visits, 4.5 antimicrobial courses, and 21.5 corticosteroid courses. These differences in resource consumption could be associated with an increase in health care expenditure for INHS, due to inhalation errors, of €23,444/yr in COPD and €44,104/yr in asthma for the considered cohorts of 100 patients. Conclusion: This evaluation highlights that misuse of inhaler devices, due to inadequate training or nonconsented switch of inhaled medications, is associated with a decrease in disease control and an increase in health care resource consumption and costs.

Outcomes and costs of treating chronic obstructive pulmonary disease with inhaled fixed combinations: the Italian perspective of the PATHOS study

Alessandro Roggeri,1 Claudio Micheletto,2 Daniela Paola Roggeri11ProCure Solutions, Bergamo, Italy; 2Respiratory Unit, Mater Salutis Hospital, Legnago, Verona, ItalyPurpose: Fixed-dose combinations of inhaled corticosteroids and long-acting ß2-agonists have proven to prevent and reduce chronic obstructive pulmonary disease (COPD) exacerbations. The aim of this analysis was to explore the clinical consequences and direct health care costs of applying the findings of the PATHOS (An Investigation of the Past 10 Years Health Care for Primary Care Patients with Chronic Obstructive Pulmonary Disease) study to the Italian context.Patients and methods: Effectiveness data from the PATHOS study, a population-based, retrospective, observational registry study conducted in Sweden, in terms of reduction in COPD and pneumonia-related hospitalizations, were considered, in order to estimate the differences in resource consumption between patients treated with budesonide/formoterol and fluticasone/salmeterol. The base case considers the average dosages of the two drugs reported in the PATHOS study and the actual public price in charges to the Italian National Health Service, while the difference in hospitalization rates reported in the PATHOS study was costed based on Italian real-world data.Results: The PATHOS study demonstrated a significant reduction in COPD hospitalizations and pneumonia-related hospitalizations in patients treated with budesonide/formoterol versus fluticasone/salmeterol (-29.1% and -42%, respectively). In the base case, the treatment of a patient for 1 year with budesonide/formoterol led to a saving of €499.90 (€195.10 for drugs, €193.10 for COPD hospitalizations, and €111.70 for pneumonia hospitalizations) corresponding to a -27.6% difference compared with fluticasone/salmeterol treatment.Conclusion: Treatment of COPD with budesonide/formoterol compared with fluticasone/salmeterol could lead to a reduction in direct health care costs, with relevant improvement in clinical outcomes.Keywords: disease management, pharmacoeconomics, direct health care costs, hospitalization

Impact of hospitalizations for bronchiolitis in preterm infants on long-term health care costs in Italy: a retrospective case-control study

Daniela Paola Roggeri,1 Alessandro Roggeri,1 Elisa Rossi,2 Salvatore Cataudella,2 Nello Martini,3 1ProCure Solutions, Nembro, Bergamo, 2CINECA Interuniversity Consortium, Bologna, 3Accademia Nazionale di Medicina, Rome, Italy Purpose: Bronchiolitis is an acute inflammatory injury of the bronchioles, and is the most frequent cause of hospitalization for lower respiratory tract infections in preterm infants. This was a retrospective, observational, case-control study conducted in Italy, based on administrative database analysis. The aim of this study was to evaluate differences in health care costs of preterm infants with and without early hospitalization for bronchiolitis. Patients and methods: Preterm infants born in the period between January 1, 2009 and December 31, 2010 and hospitalized for bronchiolitis in the first year of life were selected from the ARNO Observatory database and observed for the first 4 years of life. These preterm infants were compared (paired 1–3) with preterm infants who were not hospitalized for bronchiolitis in the first year of life and with similar characteristics. Only direct health care costs reimbursed by the Italian National Health Service were considered for this study (drugs, hospitalizations, and diagnostic/therapeutic procedures). Results: Of 40,823 newborns in the accrual period, 863 were preterm with no evidence of prophylaxis, and 22 preterm infants were hospitalized for bronchiolitis (cases) and paired with 62 controls. Overall, cases had 74% higher average cost per infant in the first 4 years of life than controls (18,624€ versus 10,189€, respectively). The major cost drivers were hospitalizations, accounting for >90% in both the populations. The increase in total yearly health care cost between cases and controls remained substantial even in the fourth year of life for all cost items. A relevant increase in hospitalizations and drug consumption linked to respiratory tract diseases was noted in infants hospitalized for bronchiolitis during the entire follow-up period. Conclusion: Preterm infants hospitalized for bronchiolitis in the first year of life were associated with increased resource consumption and costs throughout the entire period of observation; even in the fourth year, the difference versus paired controls was relevant.

Overt hepatic encephalopathy in Italy: clinical outcomes and healthcare costs

Daniela Paola Roggeri,1 Alessandro Roggeri,1 Elisa Rossi,2 Elisa Cinconze,2 Antonio Gasbarrini,3 PierAlessandro Monici Preti,4 Marisa De Rosa,2 1ProCure Solutions, Nembro, Bergamo, 2CINECA, Interuniversity Consortium, Bologna, 3Catholic University of Sacred Heart, Policlinic A Gemelli, Rome, 4Alfa Wassermann, Bologna, Italy Purpose: Hepatic encephalopathy (HE) is a recurrent severe complication of progressive hepatic cirrhosis. The aim of this study is to evaluate the average annual direct healthcare costs for the treatment of patients with overt HE in Italy. Patients and methods: This retrospective, observational study analyzed information from the database of ARNO Observatory. Patients with at least one hospitalization due to overt HE in the period from January 1, 2011 to December 31, 2011, were selected and observed during the year following the hospitalization. Costs for drugs, diagnostic and therapeutic procedures, and hospitalizations were estimated from the Italian National Health Service perspective. Results: Out of a population of 2,678,462 subjects, 381 patients were identified, of whom, 21.5% died during the first hospitalization and 5.8% during the follow-up; the survival rate was 72.7% at the end of the observation period. The direct healthcare costs per patient amounted to €13,393/year (15,295 USD) (88% for hospitalizations, 8% for drugs, and 4% for diagnostic procedures). During the follow-up, 42.5% of patients had at least one rehospitalization due to HE. Patients readmitted for HE had an average annual cost of €21,272 (24,293 USD), almost doubled if compared to patients without readmissions (€12,098 [13,816 USD]). Conclusion: This analysis showed that patients with HE had relevant direct healthcare costs, in which hospitalizations were the most important cost drivers.
