Final answer:
The PCP should start by discussing care goals with the patient and family, focusing on supportive and palliative measures. Any additional testing should be carefully considered for its effectiveness and burden. If physiotherapy contributes to the patient's well-being, it should be pursued.
Step-by-step explanation:
Having identified an aged patient as being irreversibly quite frail, the primary care provider (PCP) would be wise to begin a discussion with the patient and family about care goals and intervention limitations. This conversation is vital for understanding the patient's wishes and setting realistic expectations for care management. Withdrawal of disease-targeting medications should not be the immediate step, nor should a reduction in functional maintenance activities such as therapeutic exercise, as these can help maintain the patient's quality of life and functional independence as much as possible.
Any additional tests that should be performed on the patient would depend on their current symptoms and overall health; however, it's important to consider the effectiveness and burden of such tests in frail patients. A treatment recommendation would focus on palliative and supportive measures tailored to the patient's goals and preferences. If physiotherapy is helpful and desired by the patient, it should be continued as it can lead to improved physical functioning and reduced functional impairments.
