Patients with haematological diseases are entitled to supportive care. Considering organisational and technological development, support in the form of caring communication provided through the web is today a possible alternative. The aim of this thesis was to examine the usefulness and importance of a web-based counselling service to patients with haematological diseases. The basis for the thesis was a development project funded by the Swedish Cancer Society, which provided an opportunity to offer patients communication with a nurse through a web-based counselling service.

Four studies were performed from a patient perspective. Study I had a cross-sectional design, measuring occurrence of anxiety and depression, and these variables’ associations to mastery, social support, and insomnia among patients with haematological diseases. Study II was a qualitative content analysis focusing on conditions for provision and use of the web-based counselling service. Study III used a qualitative hermeneutical approach to focus on patients’ experiences of using the counselling service. Study IV was a qualitative deductive analysis examining how communication within the web-based counselling service can be caring in accordance to caring theory.

The results revealed that females of 30-49 years of age are vulnerable to experiencing anxiety. Low sense of mastery and support are associated with anxiety and/or depression. Being able to self-identify the need for support as well as appreciate the written medium are necessary conditions for the web-based counselling service to be used. The counselling service must also be part of a comprehensive range of supportive activities and web-based services to be useful. The main importance of the communication is that the patient’s influence on the communication is strengthened, and that the constant access to individual medical and caring assessment can imply a sense of safety. When patients share their innermost concerns and search for support, nursing compassion and competence can substantiate in explicit written responses.

A conclusion is that there is a caring potential in communication within a web-based counselling service. To make this form of communication possible, nurses should take possession of and ensure that this medium for communication is offered to patients. Nurses should also increase their knowledge of caring communication in writing and how this possibly can impact patients.
