The primary objective of dementia home care is obviously the well-being of the patient. The secondary and other objectives vary depending on the specific condition or severity of dementia, the age and the hope for improvement, recovery or preventing the worsening of symptoms. It is not possible to generalize the desired outcome of dementia home care and hence it is difficult to have a uniform approach to assess its efficacy. The efficacy of the caregiver and the services must be assessed on the basis of the pragmatic objectives that are usually present.
One of the major factors to consider is the overall state or condition of dementia. Families should assess if the symptoms are the same, improving or worsening. Some symptoms of dementia can indeed be alleviated or at least contained so they do not get worse. A few symptoms will get worse in due course of time. The severity of the symptoms can vary from time to time so that reality should also be factored into the assessment. In some cases, the job of the caregiver does not extend to include any medical care or nursing assistants. Using the symptoms as a criterion to assess the efficacy of the caregiver in such instances is not the right approach.
Another major factor that should be considered while assessing the efficacy is the general state of wellbeing. People suffering from dementia can respond to the world around them in different ways. They may show signs of improvement and there may be times when they will be quite aloof, unaware of the most obvious realities and might not respond to the care as expected. If the overall sense of wellbeing of a person improves, then it can be safely inferred that dementia home care is working. Else, you must review the specific approach.
