Severely cognitively impaired (CI) elders have trouble responding to questions about their osteoarthritis knee or hip pain, making pain management difficult. Thus, the Pain Behaviors for Osteoarthritis Instrument for Cognitively Impaired Elders (PBOICIE) was developed as an alternative. This article reports the development and psychometric testing of the PBOICIE in three studies.The 6-item PBOICIE was not associated with the Verbal Descriptor Scale, but was significantly associated with Keefe's method for observing pain behaviors in patients with knee or hip osteoarthritis, with r=.36-.55, indicating good concurrent validity. The 6-item PBOICIE was able to discriminate elders' pain behaviors before and after analgesic administration (2.9 ± 1.89 vs. 1.97 ± 1.98; p<.001).This study has shown that multifaceted pain assessments are needed in elders with osteoarthritis knee or hip pain since the observed behaviors did not parallel, but added information to verbal report. Osteoarthritis (OA) of the knee or hip is the leading cause of disability in elders (Campbell et al., 1994) and is a significant source of pain and suffering in cognitively impaired (CI) elders. It is estimated that 48% to 65% of CI elders have OA (Marzinski, 1991; The Canadian Study of Health and Aging, 1994). Without proper treatment of their pain, these elders may forego physical activities to avoid aggravating the pain, thus further impairing their physical and cognitive function and increasing their need for assistance. Other consequences of unrelieved pain include depression, sleep disturbances, withdrawal, falls and fall-related injuries, and malnutrition (Ferrell & Ferrell, 1990;Rubenstein & Josephson, 2002). Overall, unrelieved pain decreases quality of life for CI elders, adds to caregiver burden, and increases health care costs (Ferrell & Ferrell, 1990).
KeywordsAccurate assessment of pain is critical for treating CI elders with OA and evaluating the outcomes of treatment. Verbal self-report of pain, representing the individual's subjective perception of pain, is the gold standard for measuring an individual's pain, and treatment decisions are generally based upon this self-report ( . Given the high prevalence of OA in CI elders and its adverse consequences, an alternative to verbal report of pain is urgently needed for these elders.One alternative to verbal report is assessment of the verbal or non-verbal behaviors demonstrated by patients who communicate to others that they are experiencing pain (Fordyce, 1976). Activities involving the lower extremities, such as standing, walking, rising from a bed or chair, and climbing stairs, put extra pressure on the affected knee or hip joint, aggravating the pain in patients with OA. In response, elders with OA exhibit subtle but specific non-verbal behaviors indicating knee or hip pain, but these are not included on generic pain observational tools. Elders show disturbed ambulation and gestures such as moving slowly with stiffness, rubbing or holding the affected site, shifting body weig...
