Prevalence of DDEs
The prevalence of DDEs in the general chronic noncancer pain patient, OA and cLBP patient were assessed in five studies (Table 1). The prevalence of DDEs in the general chronic noncancer pain patient were estimated to be approximately 35%. In addition, the prevalence rate of DDEs in specific chronic pain conditions such as OA and cLBP were estimated to be 26 and 27%, respectively.[27,28] These studies indicate that DDEs are a widespread problem in patients with chronic pain.
