RESUMO
OBJECTIVES: Chronic hepatitis C virus (HCV) is a leading cause of hospitalization and death in populations coinfected with human immunodeficiency virus (HIV). Sofosbuvir (SOF) is a pan-genotypic drug that should be combined with other agents as an oral treatment for HCV. We performed a 5-year horizon budget impact analysis of SOF-based regimens for the management of HIV/HCV-coinfected patients. METHODS: A multicenter, prospective evaluation was conducted, involving four Italian Infectious Diseases Departments (Galliera, San Martino, Sanremo, and La Spezia). All 1,005 genotype-coinfected patients (30% cirrhotics) under observation were considered (patients in all disease-stages were considered: chronic hepatitis C, cirrhosis, transplant, hepatocellular carcinoma). Disease stage costs per patient were collected; the expected disease progression in the absence of treatment and sustained virological response (SVR) success rate for SOF-based regimens were calculated based on the literature and expert opinion. Drug prices were based on what the National Health Service paid for them. The comparison of "no treatment" disease progression costs versus the economic impact of SOF-based regimens was investigated. RESULTS: Over the following 5 years, the disease progression scenario resulted in direct costs of approximately 54 million. Assuming an SVR success rate of 90%, average SOF-based regimens cost up to 50,000 per person, resulting in a final cost of more than 56 million, so this option is not economically viable. At the average price of 12,000, SOF-based regimens, expense was 17 million, saving 68%. At this price level, the economic resources invested in treating mild to moderate fibrosis stage patients would be equal to the amount of direct costs of disease management in this stage, resulting in a valid return of investment in the short-term. CONCLUSION: Given the high rates of SVR, in the Italian Healthcare System, SOF-based regimens, price is a determinant and a predictor of the overall cost for the Hepatitis C patient's management. At the average price per therapy of 12,000 over the next 5 years, SOF-based regimens are becoming highly sustainable.
RESUMO
The impact of infectious diseases (ID) specialist consultation in the management of many types of bacterial infections has been fully demonstrated but not for bone and joint infections (BJIs). Nineteen ID Italian centres collected of data from June 2009 to May 2012. Italian guidelines (2009) were used to determine the appropriateness of the diagnostic and therapeutic process of BJIs before and after consulting an ID specialist. Data on 311 patients were collected: 111 cases of prosthetic joint infection, 99 osteomyelitis, 64 spondylodiscitis and 37 fixation device infection. A significant increase of microbiological investigations, imaging techniques and blood inflammation markers were noted after consulting the ID specialist. Moreover, inappropriateness of treatment duration, dosage, and number of administrations significantly decreased after consultation. Infectious disease specialist intervention in the management of BJIs significantly increases the appropriateness both in performing instrumental and laboratory analysis, but especially in determining the correct therapy.
