Our hospital uses a profusion of gloves. As you can see from these pictures, they come in all sizes, colors, and textures. Most are latex free, some are not. Some provide better grip when wet. Some have better grip when dry. Some people have dermatitis with one kind so they have to use another.
Therefore we are not able to standardize on a particular type and have to buy a whole rainbow of colors of gloves. This is your health care dollar at work.
