Pain Assessment with Short Message Service and Interactive Voice Response in Outpatients with Cancer and Pain: A Feasibility Study

BACKGROUND: Pain assessment and monitoring is a prerequisite for its adequate treatment in patients with cancer. We performed a feasibility study on the use of short message service (SMS) and interactive voice response (IVR) to improve pain management in patients with cancer, including terminally ill patients. METHODS: During 4 weeks, palliative patients received a daily IVR asking to provide their pain score on a numeric rating scale (NRS) with their mobile phone. If pain was moderate or high, the nurse contacted the patient the same day and, if required, adapted the treatment. RESULTS: Thirteen of the 17 invited patients agreed to participate (79%), four died during the study period. IVR/SMS provides a reliable assessment of the pain intensity, and if required, treatment can be rapidly adapted. All patients were satisfied with the intervention. There were no difficulties for the, mainly older, patients in handling this communication way on pain intensity. The mean pain score decreased from 4.78 to 3.33 (P = 0.07). The pain scale of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) decreased significantly from 56 to 35 (P = 0.047). DISCUSSION: Monitoring and managing pain with IVR/SMS in patients with cancer at home appeared acceptable and feasible, even in terminally ill patients. The reluctance for actively contacting the professional in case of increased pain intensity is circumvented in this setting. Further research, preferably in a controlled study, is needed to establish the use of this intervention in a larger patient population
