Diagnosis, prognosis, and care planning: ‘information processing’
Once a general and targeted history, examination, and investigations have been carried out (‘information gathering’), it is time for the dentist and their oral healthcare team to assimilate all of the relevant information in order to formulate a diagnosis, prognosis, and care plan for the individual patient (‘information processing’). Although the detection and diagnostic phases are each discussed separately in this book, an experienced clinician will often accomplish both phases simultaneously. It is vital to remember that diagnosis precedes treatment in all cases. Diagnosis is the art or act of inferring, from its signs and symptoms or manifestations, the nature or cause of an illness or condition. This stage is critical in order to allow the dental team and the patient to appreciate the nature, cause, and severity of the illness or condition. The prognosis is the forecast of the course of a disease or the patient’s response to treatment of the disease. This stage helps the dentist and the patient to understand how easy or difficult the treatment will be to carry out, and it allows assessment of the patient’s motivation to cure the problem. In dentistry, the oral healthcare team can only start the patient off on the road to recovery by restoring form and function to their dentition as well as helping the patient to prevent or control the disease process, so preventing its return. It is then up to the patient whether they follow this advice and maintain their oral health in the future. This plan is the formal itemized management strategy, developed by the dentist and their oral healthcare team, for the individual patient to treat the manifestations of a disease and to control it or prevent it from recurring. It can be divided into phases of therapy (e.g. prevention or control, stabilization or definitive treatment, and review, reassessment, or recall), and it should be adapted and modified during its execution for maximum benefit to the patient. It should take into account unforeseen developments in the course of the disease or the patient’s response to care. It should be written down and made clear to all parties for discussion, so that informed consent can be gained prior to implementation.
