based on what you witnessed there definitely could be an improvement of hygiene practices. i have no idea if your grandfather was exposed to any pathogen but breaches in hygiene are high on the list of infections. many times hands are washed frequently usually after and/or before each patient and new fresh gloves are used for each patient. patient or their families may not witness the handwashing if it occurred in another room or out in the hall but a change of gloves between patients is mandatory.
the phlebotomist didn't wash her hands before seeing my grandfather. see details. the lady saw other people and handeled a cup of urine before seeing my grandfather. he has type 2 diabetes alzheimers and dementia. he's 90 years old. she touched his arm to get a vein then wiped it with what i believe was alcohol or an alcohol wipe. then she stuck him placed gauze over the wound and had him hold the gauze after she touched it. we went out to eat after and he ate toast by hand. i didn't see any blood or urine on the gloves could have spread cmv hiv hep a b or c this way?
