Key Points
"Participants in the PARO group had a significantly lowered level of observed pain [-0.514, 95% confidence interval (CI) -0.774 to -0.254, P < .001] and used fewer pro re nata medications (-1.175, 95% CI -2.205 to -0.145, P = .025) than those in usual care after controlling for age, sex, cognitive function and medications. There were no significant differences in staff-rated pain, agitation, anxiety, and depression, nor regularly scheduled medications between intervention and control group. CONCLUSIONS AND IMPLICATIONS: PARO shows promise in reducing pain and medications for individuals with dementia and chronic pain in long-term care facilities. This intervention might be incorporated into daily practice as an alternative to manage pain in people with dementia. Larger randomized controlled trials with longer time frames are needed to identify further and test the use of PARO in long-term care settings." Pu 2020
