Thoughts On Hospital Telecommunications Infrastructure

Given the prevalence of broadband telecom networks in place today, hospital IT leaders may feel secure – that their networks can handle whatever demands are thrown at them. But given the progress of new health IT initiatives and data use, they still might face bandwidth problems. And as healthcare technical architect Lanny Hart notes in a piece for SearchHealthIT, the networks need to accommodate new security demands as well.

These days, he notes healthcare networks must carry not only more-established data and voice data, but also growing volumes of EMR traffic. Not only that, hospital IT execs need to plan for connected device traffic and patient/visitor access to Wi-Fi, along with protecting the network from increasingly sophisticated data thieves hungry for health data.

So what’s a healthcare CIO to do when thinking about building out hospital telecommunications infrastructure?  Here’s some of Hart’s suggestions:

  • When building your network, keep cybersecurity at the top of your priorities, whether you handle it at the network layer or on applications layered over the network.
  • Use an efficient network topology. At most, create a hub-and-spoke design rather than a daisy chain of linked sub-networks and switches.
  • Avoid establishing a single point of failure for networks. Use two separate runs of fiber or cable from the network’s edge switches to ensure redundancy and increase uptime.
  • Use virtual local area networks for PACS and for separate hospital departments.
  • Segment access to your virtual networks – including your guest Wi-Fi service – allowing only authorized users to access individual networks.
  • Build as much wireless network connectivity into new hospital construction, and blend wireless and wired networks when you upgrade networks in older buildings.
  • When planning network infrastructure, bear in mind that hospital networks can’t be completely wireless yet, because big hardware devices like CT scans and MRIs can’t run off of wireless connections.
  • Bigger hospitals that use real-time location services should factor that traffic in when planning network capacity.

In addition to all of these considerations, I’d argue that hospital network planners need to keep a close eye on changes in network usage that affect where demand is going. For example, consider the ongoing shift from desktop computers to mobile devices use of cellular networks have on network bandwidth requirements.

If physicians and other clinical staffers are using cell connections to roam, they’re probably transferring large files and perhaps using video as well. (Of course, their video use is likely to increase as telemedicine rollouts move ahead.)

If you’re paying for those connections, why not evaluate whether there’s ways you could save by extending Internet connectivity? After all, closing gaps in your wireless network could both improve your clinicians’ mobile experience and help you understand how they work. It never hurts to know where the data is headed!

  • Hub and spoke communications? A bank I used to work for 25 years ago had that; at 130 Liberty Street – across the street from #1 World Trade Center, and a short distance from the Hudson River. They had the hub in the basement. Had anything ever happened to that hub the whole comms network of that bank would have come down – luckily they were bought out by another bank before 9/11. Maybe some modified form of hub and spoke where you don’t rely on one space staying intact, undamaged, powered up and always fully functional – if such exists. Oh – that building was very badly damaged on 9/11, and might have been the same in 1993 at the first attack on the World Trade Center.

    A good disaster recover plan has at least a 2nd hub in another location, with its systems kept fully up to date at all times, ready at any moment to go live – or perhaps splitting the load at all times but with enough capacity to take itall.
