Objective: To explore possible consequences of short stays in hospitals, as these short contacts reduce the patients’ time for information and support. Method: A literature survey was carried out to get an insight in possible consequences by summarizing the state of knowledge on how men with prostate cancer undergoing prostatec-tomy surgery experience their contacts with the healthcare professionals. Results: A consequence is that often men with prostate cancer, treated with prostatectomy surgery, do not receive the individualized support, infor-mation, and dialogue they need, which leads to feelings of uncertainty, insecurity, and loss of control. The men use the Internet in their search for information and support, which makes them able to stay in control and be active, responsible partners in their own course of treatment. Conclusion: For men to feel secure and certain the accessibility of the healthcare professionals and the healthcare professionals’ ability to individualize information and support are important aspects. Practice Implications: It is relevant to provide male cancer patients with tools that can underpin their contact to the healthcare professionals. Utilizing Web 2.0 technologies, Internet based tools can support exchange-ability, towards dialogue-based contacts, between men with prostate cancer and healthcare professionals. 展开更多
