As I work in the Rehabilitation Industry (Physical Therapy, Occupational Therapy, Speech-language pathology, Athletic Training, and fitness/Wellness) a key performance sign that my business uses are: "Revenue per worked hour". This statistic drills down to the simplest units of service based on how much gross revenue was generated by one hour of work time. Also, this statistic is easy for clinical staff to understand. Obviously, the gross revenue number has other expenses such as wages, benefits, operating costs, and non-collectibles that adjust this number to a "net revenue." You can then run, budget, and forecast business suggestions from the trending of this calculation and performance over time. There are many healthcare services that use this performance indicator such as laboratory, x-ray, pharmacy, and other non-hospital companies. Describe a key performance indicator you would like to share, healthcare oriented or not
