In my career as a hospital marketer, I disliked using the infamous state market share data to measure performance—but never had anything better to use. So like many of my colleagues, I acquiesced and used the data and thought, “Well, it’s better than nothing.” But no more!
When Market Share Is Meaningless
If someone insists you take that approach, keep in mind there are three important questions you can’t answer with market share data:
- Will this year's volume match last year? (For example, there were 200 total cases last year in our market. Are there going to be 200 total cases this year?)
- How many are leaving the market altogether (aka: outmigration)?
- How many cases were performed in the brand new physician-owned surgicenter?
The point here is not to find another way to answer these questions because in reality you really can’t find any trusted available data. Instead, we must take a different approach and look at how much opportunity is out there and how much we need to make the business case.
