Development and Validation of a Mouth Assessment Tool for Orally Intubated Patients in Intensive Care Unit)

In France, according to the "medicalized information system program" national database, 230,000 adults are admitted to the intensive care unit every year, 40% of them undergoing invasive mechanical ventilation. That's 90,000 patients for whom an Oro-Tracheal Intubation (OTI) tube is inserted through the mouth into the trachea.

OTI causes oro-pharyngeal lesions, impacting on the length and quality of the patient's hospital stay.

As early as 48 hours after admission to intensive care, the patient's oral and dental condition deteriorates. Pressure lesions can occur, with the OTI probe responsible for 22% to 26% of pressure sores related to invasive equipment. Anarchic chewing also causes injuries to lips, tongue, gums, mucosa and teeth.

In time, these injuries can lead to swallowing disorders, a mechanism for feeding and protecting the airways, and impair the patient's quality of life.

Caregivers in intensive care units have developed mouth care protocols to maintain hygiene and comfort, and prevent lesions that can spread from the lips to the trachea during OTI.

Many mouth care protocols exist, but there is no "gold standard". Certain practices are encouraged as part of the prevention of Ventilator-Acquired Pneumonia (VAP) (mainly tooth brushing). Mouth care practices in France remain highly heterogeneous. In order to improve practices, it is essential not only to have best practice guidelines for preventing and treating lesions, but also to have appropriate and valid tools for assessing the oral condition of intubated patients. Good assessment is a prerequisite for good treatment/care.

To investigators knowledge, there are no oral status assessment tools specifically adapted to intubated patients.

Tools do exist for populations at risk due to age or chemotherapy, but these have often been created without multidisciplinary advice, validated in a population without OTI, and do not allow for an assessment of the state of the oral cavity appropriate to the problems of intubated patients.

It is therefore necessary to create a new tool for assessing the condition of the oral cavity, specific to oro-intubated patients in intensive care, by bringing together experts in intensive care, oral health, hygiene, wound healing and patient partners, and to validate it in this patient population. The tool must also be relevant to the fields of competence of nurses, for use in daily practice.

The aim of the protocol is to evaluate the metrological performance of the newly-developed tool for assessing the state of the oral cavity in adult oro-intubated intensive care patients.
