The first consultation with a depressed patient: A qualitative study of GPs' approaches to diagnosis.

Background: The first consultation with a depressed patient is important because many patients do not return for subsequent visits. Therefore, the first consultation provides a unique opportunity for diagnosis (if required) and treatment, but there are risks of both under and over-diagnosis. Aim: To understand how general practitioners utilize diagnosis when patients present with a new episode of depression. Method: We approached a random selection of twenty-one general practitioners (GPs) in Auckland, New Zealand and asked them to participate in a semi-structured telephone interview. The interviews explored "the first consultation for a depressed/distressed patient" were undertaken to theme saturation. Interviews were hand-written and later transcribed. Results: We identified three major themes in GPs' approach to diagnosis. The issue of diagnosis was underpinned by a complex understanding of depression and the GP role. GPs did not always make a formal diagnosis, but the experience of a patient's distress/depression was understood by drawing on a range of factors and resources. These included time, screening tools, clinician experience, and patient affect. GPs were careful about how they communicated a diagnosis, both in their documentation and in their conversations with patients. Conclusion: At an initial appointment, the distressed/depressed patient can present to their GP with various symptoms and differing degrees of distress. GPs draw upon a variety of skills and resources to negotiate these complexities. The value of a diagnosis was questioned and issues such as impairment may be more useful concepts for GPs. This is the first study to report the findings of the first visit.
