This environment still poses a risk – particularly from staff who may acquire micro-organisms within the wider health-care environment that are then transferred to service users when the staff member enters the patient zone to provide direct care. Examples include: dirty utility areas, treatment rooms, toilets, waste disposal areas etc.
In the primary care environment there are a number of occasions when clinical care is delivered in settings that are not deemed to be health care areas e.g. in the patient’s own home. These environments cannot be controlled. However, hand hygiene CAN be controlled and should be used as the first line of defence against micro-organism transmission in ANY environment where clinical care is delivered.
