Once you build it, will they come?
You can be the greatest doctor in the world, but it means nothing if patients don't know who you are or where to find you. Medical school and residency programs provide the training necessary to treat patients, but there is very little access to the business and marketing aspects of developing a medical practice.
Many private practices are moving away from guaranteed salary structures and implementing productivity based pay plans. This means that, in addition to treating patients, doctors are expected to market and grow their practice.
Employment agreements often reflect this type of pay plan, but have little information about how the practice will assist you in attracting patients. These types of employment contracts will typically provide a short period of guaranteed pay (anywhere from 6 months to 2 years). After that period, your pay will be solely based on collections resulting from your medical services.
As with any business, it takes time for a doctor to build a reputation and patient base within the practice. Make sure you know how the practice will support you in attracting new patients. And, more importantly, make sure you understand how collections are processed within the practice. It's no longer enough to be a great physician. You have to have great support. The only way to ensure that, is to have an employment contract that provides for that support.
