title: Factors associated with the accuracy of family caregiver estimates of patient pain.
abstract: This study identified factors associated with inaccurate family caregiver assessments of patient pain. Participants were 31 caregiver-patient dyads receiving hospice home care. All patients had a primary diagnosis of end-stage cancer. As expected, caregivers overestimated patient pain. The degree of disparity for each dyad was calculated by subtracting the patient's pain rating from the caregiver's rating of patient pain. Caregiver knowledge of cancer pain management was not related to the degree of disparity in pain ratings, but caregivers' experience of patient pain was significantly related to accuracy of caregivers' pain ratings. Those caregivers who 1) perceived their loved one to be in a great deal of distress secondary to pain, 2) associated greater efforts at pain relief (i.e., more medication) with greater levels of pain, and 3) were themselves distressed by the patient's pain had the most inaccurate estimates of patient pain. There was a trend for greater disparity in pain estimates to be related to poorer existential quality of life for patients. Overall, the findings suggest that health care providers need to take into consideration family members' interpretation of patient pain when providing pain management education services.
