I have no experience with play docs, but the below relates to practices/hospital environments. Nosocomial infections being what they are, I can even see my own point 😔
A study conducted in the UK found that home care significantly improves the patient's outcomes;
- risk of infection is much diminished
- for injections, it was found that no local disinfectant is needed at home
- catheter infections magically decrease at home vs hospital.
The "why" appears to be linked to our body adapting to the home pathogens.
Conversely, shared environments are much riskier. Sterilization is often touted as the be-all. However, it was shown that sterilization CAN fail:
- example 1: used instruments are not mechanically cleaned prior to sterilization; old tissue/biological samples are thick enough that a re-seed is possible
- example 2: due to flawed practices, sterilized items are exposed to pathogens or the sterile packaging is contaminated
- example 3: improper storage leads to sterilization loss (items not individually sealed in plastic) - or not double sealed
- example 4: complex instruments - colonoscopes and dental motors rank high up - cannot be steam sterilized; further, they have long thin structures or complex internals which make high disinfection challenging
So yeah, I do worry about sterilization. Because the trend is to get the cheapest worker to do the unsavory jobs; because bean counters are all about "efficiency" and "effectiveness". Because the consent form we sign basically shields the medical institution.
Enough said.
