For the analysis, the researchers controlled as many socio-demographic, geographical, and medical history factors as they could get from the insurance claims data.
According to the study, published in BMJ Open, patients who first saw a PCP for low back pain were 79 percent more likely to use prescription opioids than patients who first visited a chiropractor and 71 percent more likely than those who first went to a physical therapist.
The researchers also found patients in states with provisional or unrestricted access to physical therapy were much more likely to see a physical therapist first than patients in states with limited physical therapy access.
