Effects of controlled-released morphine on quality of life for cancer pain.

Abstract

Oncology nursing is concerned with pain relief and overall Quality of Life (QOL). The purpose of this study was to determine the effects of controlled-release morphine on QOL for patients with cancer. Eighty-three subjects were randomly assigned in a clinical trial of short-acting versus controlled-release analgesia (MS Contin, Purdue Frederick Co., Norwalk, CT). Data was collected in a repeated measures design every 2 weeks for 6 weeks yielding a total of 240 visits. Five instruments were used to assess QOL, pain, and functional status. Study findings indicate improved pain management with controlled-release MS Contin and important nursing implications for the management of analgesia-induced gastrointestinal symptoms. Through appropriate pain management with pain therapies such as controlled-release analgesia, nurses can greatly enhance QOL for the patient with cancer.
