Attitudes and appropriateness of pain management in cancer patients using pain management index

Abstract

AbstractObjectivesInadequate management of cancer pain (CP) remains a global medical problem. In this study, the aim was to assess attitudes of cancer patients towards their CP treatment and to evaluate effectiveness of pain management.MethodsA sample of 300 adult cancer patients admitted to a single hospital were face-to-face interviewed in a cross-sectional study design using a structured questionnaire. The short form of the Brief Pain Inventory was used to collect data on pain, and Pain Management Index (PMI) was calculated to assess adequacy of pain management.Key findingsMedian age of patients was 53 years (interquartile range, 43–63). Half of patients (50.5%) believed their pain therapy needs improvement. Almost half patients had severe pain at interview (49.8%). Pain interfered most with patient enjoyment of life with a mean interference score 6.13 ± 2.37. Majority of cancer patients (84.3%) received a non-opioid analgesic while a minority (15.7%) received opioid analgesic in which morphine was the most common drug. The use of non-opioid adjuvants was minimal. Mean PMI for patients was −1.15 ± 0.75 (range −2 to +1), and most patients (80.3%) had inadequate pain treatment. Gender and smoking status of patients were significantly associated with adequacy of pain management (P = 0.009 and P = 0.004, respectively). There were no associations between patient age, educational level or tumour characteristics and adequacy of pain management.ConclusionsCancer patients in this study present with severe pain and the rates of undertreatment are high. There is an urgent need to improve management plans to assure appropriate use of therapeutic modalities for treatment of cancer-related pain.
