Design outcomes

Primary

MeasureTime frame
The proportion of analgesic responders at 1 month following the initial interventional pain procedure (IPP). Patients are classified as responders if they meet both of the following criteria: 1) Pain intensity: Brief Pain Inventory–Severity Subscale (BPI–SS) decreases by = 2 points or = 30% from baseline (whichever is met) 2) Opioid consumption: MEDD does not increase by more than 10% or 5 mg/day from baseline (whichever is greater) Patients not meeting both criteria are classified as non-responders.—

Secondary

MeasureTime frame
Changes in BPI-SS after initial interventional pain procedure;Changes in opioid consumption (MEDD) after initial interventional pain procedure;Changes in breakthrough pain intensity (Numeric Rating Scale, NRS) and frequency after initial interventional pain procedure;Changes in pain interference (Brief Pain Inventory–Interference Subscale, BPI-IS) after initial interventional pain procedure;Changes in functional status (ECOG-PS) after initial interventional pain procedure;Occurrence of additional interventional pain procedure;Occurrence of procedure-related complications;Changes in cancer treatment course;Hospice referral and follow-up loss during observation;Survival status and time of death during the entire follow-up period—
