Protein folding must be maintained in their three-dimensional shape and should not aggregate or degrade. The stacking of these helices and sheets forms the tertiary structure. Hydrogen bonds bind to the polypeptide chains to form secondary structure of proteins that is the alpha helices and beta sheets. The hydrophobic amino acids need to be kept within the interior of the protein whilst the hydrophilic amino acids need to be on the exterior of the protein. These properties dictate the three-dimensional structure of the protein. For example, glycine is highly hydrophobic, whilst arginine is very hydrophilic. The mRNA specifies the sequence of the amino acids.Įach amino acid within this polypeptide chain has a different property. The beginning of protein synthesis is carried out by ribosomes that synthesize a linear chain of amino acids called a polypeptide chain.

There may be occasions when a chaperone is unavailable (for example on a home visit or when no chaperone of the appropriate sex is in the building).

Patients should raise any concerns/make any complaint via the practice’s usual comments/complaints procedure. Should you have a concern about a chaperone? The clinician will explain to you what the chaperone will be doing and where they shall be in the room. The positioning of the chaperone will depend on several factors for example the nature of the examination and whether or not the chaperone has to help the clinician with the procedure. Pleasant/approachable/professional in manner, able to put them at ease.The Patient can expect the chaperone to be: If the patient does not want a chaperone it will be recorded in the notes. Offer a chaperone to all patients for intimate examinations (or examinations which may be construed as such).Obtain and record the patient’s consent.Give the patient the opportunity to ask questions.Establish there is a need for an intimate examination and discuss this with the patient.If an intimate examination is required, the clinician will: If you would like a chaperone present during your consultation, then please advise the receptionist when booking your appointment or when checking inĬonsultations involving intimate examinations: This will be a decision based on both clinical need and the requirement for protection against any potential allegations of improper conduct.Īppropriately trained Chaperone is defined as a member or Practice staff who has nominated by a member of the Practice clinical team. If the patient still declines the doctor will need to decide whether or not they are happy to proceed in the absence of a chaperone.

However the clinician may feel that it would be wise to have a chaperone present for their mutual protection for example, an intimate examination on a young adult of the opposite gender. Patients have the right to decline the offer of a chaperone. Obvious examples of an intimate examination include examinations of the breasts, genitalia and the rectum but it also extends to any examination where it is necessary to touch or be close to the patient for example conducting eye examinations in dimmed lighting, taking the blood pressure or palpating the apex beat.Īll patients are entitled to have a chaperone present for any consultation, examination or procedure where they feel one is required. There are two considerations involved in having a chaperone to assist during intimate examinations namely for the comfort of the patient and the protection of the doctor/nurse from allegations of impropriety. Family members or friend may be present but they cannot act as a formal chaperone. In clinical medicine, a formal chaperone is a person who serves as a witness for both a patient and a medical practitioner as a safeguard for both parties during a medical examination or procedure and is a witness to continuing consent of the procedure.
