Get Ready for (Healthcare) Microgrids

By Kim Bellard, February 24, 2022

We depend on it.  Indeed, our daily lives are unimaginable without it.  The trouble is, it’s become unreliable.  Lives have been lost because it wasn’t performing when it needed to be.  It’s built around large facilities that are often decades old.  Parts of it don’t communicate/coordinate well with others.  Its workforce is aging and burnt out.  There is no person or agency charged with ensuring its resiliency. It badly needs to be rethought for the 21st century. 

Oh, you thought I was talking about our nation’s power grid?  I was talking about our healthcare system. 

The parallels are striking, and concerning.  The power outages in Texas last year caught everyone’s attention.  People went for days or even weeks without power.  Oh, that’s Texas, people elsewhere might say, so the failures were not really surprising. Maybe, but it’s not just Texas.  

Large, sustained outages have occurred with increasing frequency in the U.S. over the past two decades, according to a Wall Street Journal review of federal data. In 2000, there were fewer than two dozen major disruptions, the data shows. In 2020, the number surpassed 180.

That’s where microgrids come in.

According to Microgrid Knowledge, a microgrid is a self-sufficient energy system that serves a discrete geographic footprint, such as a college campus, factory, hospital complex, business center, military installation or neighborhood. Microgrids can operate independently from the grid using power generated on-site; they can also be used for backup power. Microgrids are designed to operate consistently in both “blue sky” and emergency situations supported by a range of energy resources, such as renewable energy, energy storage, combined heat and power or generators.

Healthcare needs to literally join in.  If there’s a hospital, nursing home, pharmacy, dialysis center, or other health care facility that hasn’t already become part of a microgrid, it’s time.  Those 1960’s-era backup generators are not going to cut it.

Healthcare needs to figuratively join the microgrid movement.  Think of hospitals as the traditional power plants, the loci of the healthcare system.  Everything revolves around them, especially as they’ve bought physician practices, developed more outpatient facilities, and consolidated.  They control how healthcare is practiced and at what cost in their community/region. They power the system.

That’s worked for us, in our dysfunctional U.S. healthcare way, but the cracks are showing. We’re effectively seeing healthcare’s versions of brownouts, or even blackouts.  If there is one thing our healthcare system is not, it is resilient.

A healthcare microgrid would more effectively keep people out of hospitals.  It would rely less on physicians, especially specialists.  It would be community-based.  It would be available 24/7, and be able to flex capacity as needed.  It would be “smart,” and incorporate as many 21^st century technologies as possible, such as home monitoring.  Unlike actual microgrids (but more like most power grids) and unlike current medical practice, it would freely cross city/state/regional lines.

Telemedicine is an example of what should be included in microgrids.  Some hospitals are bold enough to impose facility fees for telehealth visits. Those are all signs that telehealth is not part of a microgrid; it’s being coopted by the power plants – er, hospitals.

Similarly, are we really taking advantage of nurse practitioners or physician assistants can do?  Why do we even think of nurse practitioners as “nurses” or PAs just as assisting physicians?  Do we give pharmacists as much authority as their training would allow for? 

And, of course, when are we going to get AI that can be our first line of medical advice, and perhaps more?

These are microgrid questions. They’re not questions we should only be considering during times of extreme crisis, like the current pandemic; they are questions we should be answering for the next crisis.   

The analogy is not perfect. I don’t know exactly what a healthcare microgrid would look like.  But, just as I know traditional power grids are not going to be enough for our energy needs, our traditional healthcare system is not going to be enough for our healthcare needs. We need something more resilient and more localized.  We need healthcare microgrids.
