David Shaywitz wrote a must read article in Forbes called "Want To Revolutionize Health? Enable Physicians, Don't Replace Them".
This is a great description of the challenges we face to improve healthcare delivery. I founded HealthTech Capital because it takes three sets of expertise to start new healthcare delivery companies: HEALTHCARE (workflow of multiple stakeholders, complex regulatory and payment systems), TECHNOLOGY ENABLERS (mobility and social media are enablers only..we learn these lessons during the internet bubble), and USER ENGAGEMENT (patients, nurse or doctors). Nobody has these three sets of expertise (entrepreneurs or investors). We had to create an ecosystem of providers, clinicians, industry, angel and venture capitalists to bring all these expertise together! unfortunately tech VC fall back to their comfort level which is selling directly to consumers instead of dealing with complexity and irrationality of today's healthcare delivery. There is a funding gap for selling productivity tools to existing healthcare providers and an overabundance, if not exuberance, of activities for patient empowerment and direct to consumer products and services.
