Objective. To evaluate reports of adverse events following influenza immunization by sex, risk and age groups in Valencian Community from 2005 to 2011.
Methods. A pharmacoepidemiological descriptive cross-sectional observational study based on the reports of adverse events following immunization (AEFI) against influenza, registered through the Vaccination Information System (SIV) of Valencian Community from 1 January 2005 until 31 December 2011 was done.
Results. During the study period 5,107,790 doses of vaccine against influenza were reported, with an AEFI incidence of 1.94 per 100,000 (95% CI 1.59 to 2.36), and 228,094 doses of vaccine for influenza A (H1N1) pdm09 (96.45 per 100,000, 95%CI 84.52-110.06). The 70.71% (70) and 64.55% (142), respectively, of AEFI were in women. The healthcare workers group had a higher reporting rate for seasonal influenza (25.35 per 100,000; 95%CI: 17.65-36.40) and for influenza A(H1N1) pdm09 (864.13 per 100,000; 95%CI 714.38-1044.93) during the study period.
Conclusions. Vaccines against influenza administered during the study had a high safety profile in both populations with disease risk and other susceptible target groups of vaccination. Adverse reactions reported during the study mostly coincide with those described in the summary of product characteristics of vaccines.

Hepatitis C virus infection is a major health burden affecting 130-170 million people worldwide. Approximately 10-30% of those with chronic hepatitis C will progress to cirrhosis over 20-30 years. The development of new direct-acting antivirals has changed the management of the disease, allowing efficacious Interferon-free therapies superior to prior treatment regimens with minimal side effects, even in some subgroups previously thought to be difficult to cure such as cirrhotic patients.

Introduction.  Monitoring antimicrobial consumption in hospitals is a necessary measure. The indicators commonly employed do not clearly reflect the antibiotic selection pressure. The objective of this study is to evaluate two different methods that analyze antimicrobial consumption based on DDD, per stay and per discharge, before and after the implementation an antimicrobial stewardship program.
Material and methods. Comparative pre-post study of antimicrobial consumption  with the implementation of an antimicrobial stewardship program using DDD per 100 bed-days and DDD per 100 discharges as indicators.
Results. Hospital bed days remained stable and discharges increased slightly along the period of study Antibiotic consumption in DDD per 100 bed-days decreased by 2.5% versus 3.8% when expressed as DDD per 100 discharges. Antifungal consumption decreased by more than 50%.
Conclusions. When average hospital stay decreases, reductions in the consumption of antimicrobials with an antimicrobial stewardship program system occur at the expense of reducing the number of patients receiving treatment, while increases occur due to longer durations of treatment.
