癌症病人之止痛藥服藥遵從性與障礙因子疼痛處理滿意度的相關探討

Relationships of Analgesics Adherence to Barriers and Satisfaction of Pain Management in Cancer Outpatients

疼痛是癌症病人重要的問題，使用止痛劑是緩解疼痛的主要方法，但是要使病人服藥遵從卻十分不易，本研究目的在評估門診癌症疼痛病人的服用止痛劑的遵從性，並了解影響服藥遵從性的相關因素。 研究方法為橫斷式研究，資料來源為一大型研究，共分析100位癌症病人，研究資料及工具包含病人之個人及疾病基本資料、台灣版服藥遵從性量表、病人台灣版障礙量表、家屬台灣版障礙量表、中文版簡明疼痛量表、APS疼痛滿意度量表及Karnofsky功能評估量表，資料分析採描述性分析、t檢定、F檢定、相關檢定（Pearson correlation）及迴歸分析（regression analyses）。 結果顯示門診之癌症疼痛病人服藥遵從性屬低至中度，且病人止痛藥障礙因素及對疼痛處理的滿意度為癌症病人服藥遵從性的預測因素（p<.05）。研究結果提醒醫療團隊降低病人止痛藥障礙因素及改善對疼痛處理的滿意度，可改善癌症疼痛病人服藥的遵從性。Pain is one of the major problems faced by cancer patients. Use of analgesics is a major treatment modality in management of cancer pain. Achieving adequate adherence to analgesics regimen is difficult. The purpose of the study was to investigate the level of adherence with analgesics regimen and to explore the related predicting factors. The study was part of a large study. A total of 100 patients participated in the present study. Instrument consisted of the Taiwanese Version of Medication Adherence measure, the Barriers Questionnaire-Taiwan Form (BQT), Brief Pain Inventory-Chinese version (BPI-C), Karnofsky Performance Status (KPS), and a demographic questionnaire. Descriptive analysis, t-test, F-test, Pearson correlation, and multiple regression analysis were used for data analysis. Results show that the level of adherence with analgesics regimen was low and the patient-related barriers and satisfaction of pain management were the predictors for analgesics adherence in cancer (p<.05). The survey suggests that the medical team should decrease patient-related barriers and improve satisfaction of pain management, which will in turn improve analgesics adherence in cancer.
