I think its always useful to know the reasons why medical gloves are used and when they should and should not be used . This is part of our policy on our unit developed from World Health Organization Patient Safety Save Lives Clean Your Hands.
Medical gloves are defined as disposable gloves used during medical procedures; they include:
1. Examination gloves (non sterile or sterile)
2. Surgical gloves that have specific characteristics of thickness, elasticity and strength and are sterile
3. Chemotherapy gloves
Medical gloves are recommended to be worn for two main reasons:
1. To reduce the risk of contamination of health-care workers hands with blood and other body fluids.
2. To reduce the risk of germ dissemination to the environment and of transmission from the health-care worker to the patient and vice versa, as well as from one patient to another.
Inappropriate glove use:
1. The use of gloves when not indicated represents a waste of resources and does not contribute to a reduction of cross-transmission.
2. It may also result in missed opportunities for hand hygiene.
3. The use of contaminated gloves caused by inappropriate storage, inappropriate moments and techniques for donning and removing, may also result in germ transmission.
Summary indications for gloving and for glove removal:
Gloves on:
1. Before a sterile procedure.
2. When anticipating contact with blood or another body fluid, regardless of the existence of sterile conditions and including contact with non-intact skin and mucous membrane.
3. Contact with a patient (and his/her immediate surroundings) during contact precaution.
Gloves off:
1. As soon as gloves are damaged (or non-integrity suspected).
2. When contact with blood, another body fluid, non-intact skin and mucous membrane has occurred and has ended.
3. When contact with a single patient and his/her surroundings, or a contaminated body site on a patient has ended.
4. When there is an indication for hand hygiene.
Summary of the recommendations on glove use:
1. In no way does glove use modify hand hygiene indications or replace hand hygiene action by rubbing with an alcohol-based product or by handwashing with soap and water.
2. Wear gloves when it can be reasonably anticipated that contact with blood or other body fluids, mucous membranes, non-intact skin or potentially infectious material will occur.
3. Remove gloves after caring for a patient. Do not wear the same pair of gloves for the care of more than one patient.
4. When wearing gloves, change or remove gloves in the following situations: during patient care if moving from a contaminated body site to another body site (including a mucous membrane, non-intact skin or a medical device within the same patient or the environment).
5. The reuse of gloves after reprocessing or decontamination is not recommended.
So providing that the doctor washes their hands ( and don't be afraid to ask them to; they should before they begin any exam and after the exam) and you do not have any broken areas on your skin, then gloves do not have to be worn when examining a person; doing so just is a waste of resources . Also the wearing of gloves can reduce the examiners ability to detect subtle changes.
Hope this helps to clarify the use of medical gloves during an exam or procedure.
