We found considerable geographic variation in the use of some service categories, although not all. We also found that local communities used very different combinations of types of services to produce medical care, that some service categories were substituted for others, and that the mix of service categories differed even among sites with high or low total medical utilization levels. Home health and durable medical equipment were major drivers of total geographic service use variation because of their variation across sites. Read More
