Gloves and safety culture in hospitals
I read with interest your article entitled “Culture of safety keeps hospital workers from becoming patients” in the above-mentioned publication. You have correctly pointed out the concerns healthcare workers have about safety, such as contracting diseases like HIV or hepatitis from needlestick injuries. However, some clarifications are needed regarding the use of medical gloves, which all healthcare personnel rely on for protection against viral transmission and infectious diseases.
First, there is no doubt that in the past, latex gloves with uncontrolled levels of protein and powder had caused allergic reactions to a number of protein-sensitive individuals, and created public concerns and leafs about using latex gloves. In recent years, result of intensive research undertaken and advancements achieved in manufacturing technology have led to creation of a new generation of low protein, low powder or powder-free latex gloves that significantly lowers the risk of allergic reactions. A number of recent hospital studies undertaken in the U.S., Canada, Finland and Germany have in fact shown that the use of these improved latex gloves not only vastly reduces the incidence of allergy hilt also allows many latex sensitive individuals donning synthetic gloves to work alongside their coworkers wearing latex gloves without suffering ill effects. (References (1) through (7))
Although synthetic alternatives are now available in the market place, many of them do not have the superior glove properties of latex, such as effective barrier protection, comfort, fit, high resistance to tear and puncture, and tactile sensitivity. For example, widely used vinyl (PVC) gloves have been shown consistently by many studies to have inferior barrier performance; leakage rates as high as 63% for vinyl have been reported compared to 7% for latex gloves during use (References (8) through (16)). Other synthetic gloves may be better than vinyl, but they are more costly. Furthermore, the ability of latex to reseat after very small needle punctures enhances the barrier effectiveness of latex gloves. Such property is not found in synthetic gloves like vinyl and nitrile (References (17) through (18)).
Therefore, good safety culture calls for the use of low-protein latex gloves in hospitals and other healthcare facilities for majority of the workers; latex allergic individuals should be provided with high quality synthetic gloves with adequate barrier protection.
Second, it is incorrect to say that the recent appearance of colored latex gloves (dental variety) in the market place has hindered the differentiation between latex gloves, which are mostly in their native beige color, and brightly colored synthetic gloves, and led to confusion among latex allergic individuals. This might be so if all synthetic gloves were brightly colored. In fact, a large proportion of synthetic gloves (particularly vinyl) have a beige color similar to latex. Clearly, this issue needs to be resolved if a color strategy were to be adopted. Alternatively, easy distinction between latex and synthetic gloves could be made possible by simply labeling the synthetic gloves, which constitute only about 1/5 of the total medical gloves used.
With the adoption of a proper safety culture, hospitals can be safe places for healthcare personnel to work in. It is hoped that the Food and Drug Administration would be able to come out, without further delay, with its New Rule on medical gloves which requires, inter alia, latex gloves not to exceed upper limits set for protein and powder. The New Rule should also identify the type of synthetic material, as there are wide variations in the properties, performance and health risks associated with synthetic gloves made of different materials.
If there is any additional information or clarification you need, please feel free to contact me.
