New York State health officials said yesterday they had spoken to the Centers for Disease Control several times over the past few years about making the use of medicine vials safer.
"I don't think we have a lot of patient advice in terms of how they should act with their physician over the use of multidose vials," he said.
With leaders from developing countries, the World Health Organization (WHO), UNICEF, vaccine manufacturers, academia and nongovernmental organizations around the table, this week's roundtable is well positioned to capture viewpoints from key stakeholders, as well as to identify areas for optimizing the use of vaccine vials for a variety of situations.
One quarter of the patients required five treatment sessions and 82% of sessions required the use of two vials of PLLA.
In a recent paper CDC's investigators outline one possible way in which inappropriate use of medication vials intended for single-person may result in large HCV outbreaks.
A plausible but again unprovable guess is that the source of the ethanol was incomplete flushing after prior use of the vials to contain ethanol-based remedies, or perhaps ethanol was also used in the rinsing process.
Other infection control breaks such as mishandling of sterile materials and improper use of multidose vials have been frequently implicated in the transmission of bloodborne viral and bacterial infections, but were not studied in this survey [ 13, 15].
Healthcare centers were primarily responsible for amplification of the outbreak through reuse of needles and syringes and use of multidose vials in healthcare centers due to poor training in safe injection practice (WHO, unpub. data).
False positives due to contamination during handling and analyses were avoided by washing the glassware multiple times (soap and water, acetone, chloroform), the use of disposable vials when possible and changing gloves after the preparation of each sample.
Thus, in addition to use of shared vials for administration of heparin (4 ), physiological saline solution (5 – 7 ) or anesthetics (8, 9 ), procedures carried out with contaminated equipment (10, 11 ) or inappropriate practices of health personnel (12 ) have been proposed as mechanisms of nosocomial transmission.
