“…In surveys of surgical patients, it has been found that approximately half of all hospitalized postoperative patients failed to receive adequate pain relief ( Jacox, Ferrell, Heidrich, Hester, & Miaskowski, 1992;Jurf & Nirschl, 1993). Patients reporting moderate to high levels of pain received less than half of the pain medication that was ordered (Kitson, 1994;Tittle & McMillan, 1994). This underutilization of prescribed medications may be related to the fact that health care professionals often evaluated pain at lower levels than patients re-ported and used objective symptoms rather than the patient's self-report to assess the patient's pain (Bowman, 1994;Mateo & Krenzischek, 1992;Olden, Jordan, Sakima, & Grass, 1995;Paice, Mahon, & Faut-Callahan, 1995;Stephenson, 1994;Webb & Kennedy, 1994;Zalon, 1993).…”
