A few weeks ago I gave a talk at the 2013 Pelvic Health Conference in Denver, Colorado, and my focus was on the need for healthcare marketers to build communities of shared interest. These are niche online communities that give patients the opportunity to engage with others who are going through, or have gone through, similar circumstances. When you get a diagnosis, it is natural to want to seek out others who have faced the same set of challenges. Their experience and guidance can be invaluable. And the healthcare provider can inject high quality information and medical expertise, and make available important resources for those visiting the community. The provider is the host and the facilitator, making the interactions possible – helping to create community.
