Yes, you are quite right. Strictly speaking, when the clinic cleaning services team arrives for their shift, the resident doctor has already left for the evening. But in regard to the way that these cleaning teams go about their work, the doctor may as well be in the house. Public and private hospitals and clinics servicing large communities continue to regard these cleaning teams as important and valued members of their staff, whether they are employed internally or are operating under contract.
These days, if such cleaning staff are employed locally, they need to be properly trained and licensed to carry out their tasks. They also need to be thoroughly vetted to ensure that they are of good character and in good standing. But private institutions in particular prefer to rely on, in turn, privately run service providers. They have already gone well beyond the required minimum standards, given the experience of servicing the clinical and medical professions.
The doctor is able to leave the house, if you will, safe in the knowledge that all his patient records are not in danger of prying eyes. The contracted cleaning professionals, vetted and cleared for work, are taught to practice the utmost discretion where sensitive and personal medical information is concerned. It is quite possible that during their industriously efficient work, they may be privy or exposed to such personal information.
As they say, whatever is shared here will not go out the door. The professional cleaning team may as well be medical doctors, given the nature of their clinical precision. Utilizing sustainable and germ-free detergents, and wearing protective clothing at all times, they are always able to maintain a clean environment that is also healthy for doctor and patient.
