Assessment of Quality of Life in Patients With Chronic Cancer Pain Using Brief Pain Inventory. A Prospective Observational Study

This is a Prospective Observational Study. All new patients in chronic pain OPD are been administered BPI questionnaire as a standard of practice in our institute, in the language best understood by them e.g. English, Hindi, Marathi, Bengali. The participants will be asked to complete it once during their first visit to the pain clinic, before the start of treatment or ongoing treatment for pain (Baseline) and then during subsequent visits (Follow up). Most chronic pain patients are advised to follow-up by one to two weeks. Patients who are willing to participate in the study will be included after obtaining an informed consent. Data will be collected from BPI, Chronic Pain Record form and EMR and will be analyzed. Demographic data, diagnosis, pain data sheet, drug treatment as well as other form of therapies will be recorded. There will be no direct communication with the patient and data of quality of life will be retrieved from pain clinic records.

The Brief Pain Inventory (BPI) long form and short form questionnaire is a validated multidimensional pain assessment tool developed by Cleeland and Ryan. It is one of the most commonly used measures for assessing both pain severity and interference with functions in adults with cancer, thereby satisfying two recommendations (assessment of pain to include both intensity and interference) set by the Initiative on Methods, Measurements, and Pain Assessment in Clinical Trials (IMMPACT) group. It is brief, self administered, easily understood and can be administered to large numbers of patients,.

It contains three questions regarding pain intensity and seven regarding pain interference that are rated on an ordinal numerical scale with anchors of 0 (no pain/interference) to 10 (maximum pain/interference). Pain intensity is measured according to the worst pain experienced in the last three days, average pain in the last three days, and current pain. Pain interference assesses how that pain has affected general activity, mood, walking ability, normal work, relations with others, sleep, and enjoyment of life. The sum of the scores of the pain intensity items represents the summed pain intensity score and the sum of the scores on the pain interference items represents the summed interference score. In addition, the patient enters his pain localization on a body drawing and can give details of his current medication.
