There can be no question that 2012 was a bumper year for healthcare IT. The sheer volume and size of investments was enormous. Fast-forward a few months and the pace doesn't seem to be slowing. In February alone, there were over 30 deals closed for a total of $107.95 million invested. This represents twice the deal volume of the same time last year.

Examining information from InterWest Partners, there's clearly one big driver for this spending and that's Big Data/Analytics. As you may expect, the healthcare industry has enormous hopes for this area and is more than willing to invest. In fact, one of the hot startups of the moment is xG Health Solutions and this is backed by industry stalwart Geisinger Health System.

There’s a clear disconnect in focus between investors and entrepreneurs. Telehealth and mobile diagnostics are the two areas that appear to excite entrepreneurs. Yet this excitement is more of a murmur for the investment community.

Looking around at the genuine impact these two technologies are already having on patients' lives, it's difficult to understand why there should be such hesitation to invest. Yes, Big Data/Analytics will help to drive new efficiencies and power new research initiatives but will it be capable of disrupting the current treatment system?

Let me expand on this a little further.

The continued development and coverage of mobile networks is having a profound effect in the way healthcare is provided. This is especially true in poorer countries. India is perhaps the leading proponent of this. A number of Indian healthcare organisations are now using the rapid spread of national mobile networks to drive new telehealth services. The impact on patient care is proving enormous.

One need only look at the area of peritoneal dialysis to see this in action. Previously, patients would need to travel to hospital for this treatment. For many, this was no small trip, particularly if you live in parts of rural India. However, with the ready availability of new online services, patients are able to administer the dialysis from home while being monitored remotely by hospital physicians.

Compare this with similar dialysis services in the U.S. Here, fewer than 10% of patients are treated remotely. Most are requested to visit a hospital three times a week. One Indian doctor notes that even if the U.S. could move only a small number of its dialysis patients onto a telehealth service it could save millions upon millions of dollars in Medicare and Medicaid.

The whole notion of mobile health is a hot topic and was widely discussed at this year's Mobile World Congress. A joint report from the GSMA and PwC suggests that telehealth services could cut health care costs in developed countries by over $400 billion. The report explores several key services that are instrumental here, ranging from remote monitoring to digitization and simplified access of health records.

Even though there are significant financial incentives to drive ahead with telehealth and mobile services there are clear challenges. Aside from the lack of investment, we also need to consider the enormous cultural shift. According to research from Pew Internet & American Life Center, fewer than 10% of American mobile phone users have downloaded a health app. One could argue that downloading MyFitnessPal doesn't quite compare with a life-saving dialysis app, but doesn't this figure suggest a potential apathy. Are people ready for the additional responsibility that telehealth brings?

What's clear is that momentum in healthcare IT is building. Yes, entrepreneurs, investors and healthcare organisations may differ on priorities, but what's incontestable is that we're gradually moving towards a digital, collaborative and connected healthcare system. A system that is no longer centred around a hospital but around a network. A system that enables us to use our connected devices to drive our own physical wellbeing.

Do you believe that a new era of digital healthcare is upon us? What are the main obstacles that we need to overcome? Have you tried any telemedicine services? If so, how do you rate your experience? Let me know what you think.
