Medical guidelines help doctors understand the best way to treat health conditions. Surprisingly, many doctors do not adhere to them, and this is a problem, according to a new study by scientists at University of Utah Health and MDGuidelines. People with lower back pain injury miss 11 more days of work in a year when they only receive treatments for lower back pain that are not recommended by medical guidelines compared to people treated according to guidelines. The findings publish in PLOS ONE on June 17.
