Just by casual observation, I have asserted that a hospital was more likely to acquire a surgical robot if a nearby competitor hospital had already done so. But this was an untested conclusion, based on viewing websites and highway signs, particularly from community hospitals, like above. So I was intrigued to see this great article by Huilin Li (Department of Population Health, New York University) and others in Healthcare. From the abstract:
Background
The surgical robot has 
been widely adopted in the United States in spite of its high cost and 
controversy surrounding its benefit. Some have suggested that a “medical
 arms race” influences technology adoption. We wanted to determine 
whether a hospital would acquire a surgical robot if its nearest 
neighboring hospital already owned one.
Methods
We
 identified 554 hospitals performing radical prostatectomy from the 
Healthcare Cost and Utilization Project Statewide Inpatient Databases 
for seven states. We used publicly available data from the website of 
the surgical robot's sole manufacturer (Intuitive Surgical, Sunnyvale, 
CA) combined with data collected from the hospitals to ascertain the 
timing of robot acquisition during year 2001 to 2008. One hundred thirty
 four hospitals (24%) had acquired a surgical robot by the end of 2008. 
We geocoded the address of each hospital and determined a hospital's 
likelihood to acquire a surgical robot based on whether its nearest 
neighbor owned a surgical robot. We developed a Markov chain method to 
model the acquisition process spatially and temporally and quantified 
the “neighborhood effect” on the acquisition of the surgical robot while
 adjusting simultaneously for known confounders. 
Results
After adjusting for 
hospital teaching status, surgical volume, urban status and number of 
hospital beds, the Markov chain analysis demonstrated that a hospital 
whose nearest neighbor had acquired a surgical robot had a higher 
likelihood itself acquiring a surgical robot (OR=1.71, 95% CI: 
1.07–2.72, p=0.02).
Conclusion
There
 is a significant spatial and temporal association for hospitals 
acquiring surgical robots during the study period. Hospitals were more 
likely to acquire a surgical robot during the robot's early adoption 
phase if their nearest neighbor had already done so.

To me, the term “keeping up with the Joneses” suggests trying to show that by buying a new car or new and better clothes or joining a country club or whatever proves that I’m as well off, in a material sense, as my neighbors are. In other words, it’s all about status and the outward perception of wealth.
The mentality behind the robot acquisition is likely different. The hospital that buys one after a nearby hospital does may be motivated mainly be a fear of losing business if it doesn’t. This could happen because either rainmaker surgeons direct more of their business to the competing hospital or because patients perceive the competing hospital as more modern and likely to provide better care. So, even if the hospital CEO and trustees don’t think it’s a good idea to buy one, it may do so anyway because they think sustaining the hospital’s business model depends on it even if medical outcomes are no better and costs are higher. I think the whole dynamic highlights the need to do everything possible to ensure that patients have accurate information about the cost and efficacy of medical technology and the treatment alternatives available to them.
Barry, I think this very thing happened at Paul's hospital while he was CEO - correct me if I'm wrong about the motivation, Paul. These pressures are hard to resist, which even more points to the necessity for the profession to assert some leadership, advocating for limited rollouts in a few academic centers while the device/procedure is studied. The AMC's could be chosen by lottery or a rotation.(I am speaking off the top of my head here, but there are many ways to get control of this out-of-control situation without regulators becoming involved.)
