Cost and economic burden of adverse events associated with metastatic melanoma treatments in five countries.

OBJECTIVE: To estimate per-event cost and economic burden associated with managing the most common and/or severe metastatic melanoma (MM) treatment-related adverse events (AEs) in Australia, France, Germany, Italy, and the UK. METHODS: AEs associated with chemotherapy (dacarbazine, paclitaxel, fotemustine), immunotherapy (ipilimumab), and targeted therapy (vemurafenib) were identified by literature review. Medical resource use data associated with managing AEs were collected through two blinded Delphi panel cycles in each of the five countries. Published costs were used to estimate per-event costs and combined with AEs incidence, treatment usage, and MM prevalence to estimate the economic burden for each country. RESULTS: The costliest AEs were grade 3/4 events due to immunotherapy (Australia/France: colitis; UK: diarrhea) and chemotherapy (Germany/Italy: neutropenia/leukopenia). Treatment of AEs specific to chemotherapy (Australia/Germany/Italy/France: neutropenia/leukopenia) and targeted therapy (UK: squamous cell carcinoma) contributed heavily to country-specific economic burden. LIMITATIONS: Economic burden was estimated assuming that each patient experienced an AE only once. In addition, the context of settings was heterogeneous and the number of Delphi panel experts was limited. CONCLUSIONS: Management costs for MM treatment-associated AEs can be substantial. Results could be incorporated in economic models that support reimbursement dossiers. With the availability of newer treatments, establishment of a baseline measure of the economic burden of AEs will be crucial for assessing their impact on patients and regional healthcare systems.

Monitoring the rate of hospitalization before rotavirus immunization in Italy utilizing ICD9-CM regional databases.

BACKGROUND: Recently, two Rotavirus (RV) vaccines were licensed in Italy, rendering RV illness a vaccine preventable disease. To assess the RV hospitalization rate in Italy, a study focused on the Regional hospital discharge forms (HDD) databases was carried out. RESULTS: Regional HDD databases from Piemonte, Veneto, Friuli-Venezia-Giulia and Marche were analyzed. A total of 434,335 hospitalizations were counted in the study timeframe and 13,234 VE diagnoses (3% of hospitalizations) were collected. A total of 8546 RVE cases (2% of hospitalizations, 64% of all VE) were observed, of which 1.2% were primary diagnoses (PD) and 0.8% secondary diagnosis (SD). The RVE hospitalization peak (4.9%) was observed at the age of 1 year (4.5% in 7-12 months of age) with a median hospital stay of 4.4 days (s.d +/- 4.2). Two deaths (out of 8546 RVE cases) were identified. PATIENTS AND METHODS: Regional HDD databases with the diagnosis of viral enteritis (VE) and RV enteritis (RVE) (ICD9-CM code 00861-69 and 008.8) in any position of the first 20 discharge diagnoses in children aged less or equal to 5 years between 2001 and 2005 were requested. CONCLUSION: Despite some limitations due to the HDD synthetic contents and low potential for clinical interpretation, the Regional HDD databases, including PD and SD, may be a useful tool for monitoring the clinical impact of RV vaccination introduction in Italy.

[Hospitalisation associated with Rotavirus gastroenteritis in Italy, 2001-2003, evaluated by means of ICD9-CM diagnostic codes]. / Ricoveri per enterite da Rotavirus in Italia valutati mediante analisi delle Schede di Dimissione Ospedaliera negli anni 2001-2003.

Rotaviruses (RV) are the most common etiological agents in acute gastroenteritis (GE) in children in the first years of life. Data from the national scientific literature show that RV is responsible of 26% of all cases of hospitalisation for diarrea in children, resulting the most frequently identified agent. The Italian database of hospital discharge, freely available from the web site of the national Ministry of Health, was searched to investigate the epidemiology of RV gastroenteritis. The mean number of hospitalisation for RV enteritis in children in the first 4 years of live was 4.758 in the years 2001, 2002 and 2003, representing 84% of viral enteritis. RV was identified as agent in 17% of all intestinal infectious diseases in this age group. This percentage shows the important role of RV in severe gastrointestinal infections; it is however much lower than the value expected from specifically performed surveys. This underestimation may be attributed to the high number of undefined gastroenteritis found in the database (54%), to the scarce sensitivity of the hospital discharge code, and to the fact that the analysis was performed using only the principal diagnosis. A specific immunisation strategy, safe, effective, cost-effective and easy to perform, could have a great impact on the incidence of the disease and on the associated costs.
