25. Difficulties with interferon treatment in former intravenous drug users
OBJECTIVES: Intravenous drug use accounts for most of the new hepatitis C infections worldwide. Although there is an urgent need for antiviral treatment of infected intravenous drug users (IDUs), several factors compromise their treatment including lack of treatment adherence and high dropout rate. The aim of this study was to compare antiviral treatment-rel

26. A novel experience in the use of control charts for the detection of nosocomial infection outbreaks
OBJECTIVE: This study aims to compare different control charts to monitor the nosocomial infection rate per 1,000 patient-days. METHODS: The control charts considered in this study were the traditional Shewhart chart and a variation of this, the Cumulative Sum and Exponentially Weighted Moving Average charts. RESULTS: We evaluated 238 nosocomial infections t

29. STATISTICAL CONTROL OF MULTIPLE STREAM PROCESS / CONTROLE ESTATÍSTICO DE PROCESSOS MULTICANAL
In a multiple stream process (MSP), a same quality variable is measured in several streams in parallel. The first tool proposed for monitoring MSPs was the Group Control Chart (GCC) by Boyd (1950). These schemes are recommended in textbooks and guides as Pyzdek (1992) and Montgomery (until 3rd edition, 1997). Its efficiency is impaired by the presence of cro

31. Reliability prediction for structures under cyclic loads and recurring inspections
Abstract: This work presents a methodology for determining the reliability of fracture control plans for structures subjected to cyclic loads. It considers the variability of the parameters involved in the problem, such as initial flaw and crack growth curve. The probability of detection (POD) curve of the field non-destructive inspection method and the cond

35. Gerenciamento de risco em tecnovigilância: aplicação dos conceitos seis sigma e técnica delphi para o desenvolvimento e validação de instrumento de avaliação de material médico-hospitalar / Risk management in technovigilance: application of Six Sigma concepts and the Delphi Technique for the development and validation of a medical-hospital material assessment instrument.
Hospital risk management is a complex process, which involves multidisciplinary management actions. Its goal is to set up a system to monitor and identify the probable origin of adverse events and their damage; make appropriate decisions; and perform actions related to Pharmacovigilance, Hemovigilance and Technovigilance. The latter, among other functions, p
