Involvement Of Primary Care Physicians Research Articles

Diagnosis and management of dementia in primary care at an early stage: the need for a new concept and an adapted procedure.

Diagnosis of dementia in primary care is both difficult and important. The recommendations by several authors to improve the diagnosis of dementia by general practitioners are important, but insufficient. It is argued that perhaps the disease concept in itself is a cause of confusion for clinicians. Primary care physicians need an adapted procedure, gradually leading to the final diagnosis of dementia. It has to be a stepwise labelling strategy, using global descriptions and non-disease specific labels in the beginning, ending up with well-defined disease criteria. In this process, there is circularity: previous diagnoses have to be kept in mind because symptoms and signs may gradually change during the progression of the disease, leading to reconsideration of previous deleted options. To frame this properly, the primary care physician needs to adopt a broad "frail elderly" geriatric concept. Implementation of this concept not only helps the diagnostic process, but also stimulates the care for dementing patients and their caregivers. Relevant arguments for early diagnostic involvement of primary care physicians can be put forward on condition that a new concept, adapted procedures and adapted instruments are used.

Driving Forces for and Barriers to Nutrition Guidance Practices of Dutch Primary Care Physicians

Determinants of the nutrition guidance practices of primary care physicians (PCPs) were studied using a mail questionnaire developed on the basis of focus group discussions, in-depth interviews, and literature review. The questionnaire was sent to a nationwide random sample of 1000 PCPs (in practice for between 5 and 15 years).The net response rate was 64%. Multiple regression analysis was used to identify determinants of nutrition guidance practices. The independent variables studied were the perceived barriers to nutrition guidance practices, characteristics of the respondents, and nutrition attitudes and beliefs of PCPs. As determinants of nutrition guidance practices, we identified both perceived barriers (which exert a negative influence) and driving forces (which exert a positive influence).The driving forces observed in PCPs were an active interest in the effect of nutrition on health and disease, a basic level of nutrition knowledge, and positive attitudes towards nutrition guidance practices. Although perceived barriers can be strong, negative determinants of being involved in nutrition guidance practices, in future, it may become more important to stress the driving forces that positively determine the involvement of PCPs in nutrition guidance practices.

The Virgil role.

The referral of a patient for subspecialty consultation and examination is but one facet of the primary care physician's involvement with his patient. Using examples from my practice, I argue that the term "gatekeeper" is an inadequate term for describing what the primary care physician does, or should do, for his patient. "Virgil Role" is offered as an alternative expression based on a proposed parallel between Dante's passage through the Inferno accompanied by his mentor-guide, Virgil, and a sick person's journey through his personal Hell of illness and the labyrinthine medical care system, guided by his physician.

The diffusion of new genetic tests for predicting disease.

This paper examines the pathways by which new genetic tests will become available to the public. In view of the scarcity of genetic specialists, the pathway is likely to involve primary care physicians. Other pathways entail state-mandated testing, community-based programs, or testing by laboratories without much involvement of primary care physicians. When testing does become available the "destination" will be either family-centered testing or population-oriented screening. The deterrent to screening will not be the inability to detect disease-causing mutations but the costs and attitudes of providers and the public. When tests are provided primarily to provide information about risks to future children, some people will oppose screening on religious or moral grounds. When there are no inexpensive treatments, some will fear that insurance companies and employers will use tests to deny them health care coverage. Some may not want to know their risks for disorders about which little can be done. For common, multifactorial disorders, genetic tests will have low predictive value. Because of these problems, the decision to be tested, regardless of the destination, requires that "testees" be fully informed and consent to testing. When acceptance rates are low, screening is less likely to be cost-effective; family-centered testing becomes the default destination.
