Abstract

OBJECTIVE: To determine, using the Delphi method, standardized recommendations for the follow-up of patients undergoing an interventional procedure for the treatment of chronic pain in Spain. METHODS: First, a systematic literature review was performed to identify the literature on the management of patients with chronic pain undergoing interventional techniques; subsequently, a two-round Delphi survey with 108 questions was conducted. The questionnaire was validated by a Scientific Committee (5 experts) and sent to 47 experts specialized in chronic pain. "Consensus" or "intermediate consensus" was determined when =75% or <75% to =65% of the experts selected the same answer for each item, respectively. Then, a face-to-face deliberation process was held with the Scientific Committee to analyze and discuss the results. RESULTS: The questionnaire was completed by 24 panelists (51%). Consensus was reached on 88.4% of the questions. The panelists identified pain, drug consumption, and quality of life as essential variables in the follow-up of patients with chronic pain. Consensus was reached on most of the scales/questionnaires to be used in measuring outcomes during follow-up, except for psychological status. Regarding the follow-up frequency, in radicular spinal chronic pain, a consensus was reached on the first visit 1-2months after the intervention, during the first year, at 1, 3, 6, and 12months, and then every 6months thereafter. For non-radicular spinal chronic pain, the first visit 1-2months after surgery was agreed upon, however, there was no consensus on follow-up during the first year. For non-spinal chronic pain, consensus was reached regarding the first visit at 1-2months after surgery and during the first year at 1, 3, 6, and 12months. No consensus was reached on follow-up frequency for oncological chronic pain. After receiving a permanent neurostimulator implant for chronic pain, the first visit was agreed upon at 1-3weeks, during the first year, at 2weeks, 1, 3, 6, and 12months, and after, every 6months. For intrathecal infusion, it was agreed that the first visit should occur during the first month, and thereafter whenever the pump requires a refill. CONCLUSIONS: These findings provide recommendations in relation to the frequency of follow-up and the scales to be used with chronic pain patients undergoing interventional techniques in Spain.
