About this trial
The IMPROVE study is a randomized, controlled, cross-over trial designed to compare intrathecal pump refills performed at home with those carried out in the hospital. Intrathecal drug delivery (IDD) is used in patients with chronic pain or severe spasticity. Use of IDD requires the performance of pump refills about 4-6 times a year which may be a burdensome and stressful experience for patients and their caregivers. Hospital visits can increase stress, pain, and caregiver strain, while early pilot studies suggest home-based refills may be both safe and more comfortable.
Eighty-two adult patients in Belgium with an implanted intrathecal pump will be enrolled in the IMPROVE study. Each participant will undergo four refill procedures: two at home and two at the hospital, in randomized order.

Trial outcomes
Primary outcomes
Patient Comfort
Patient comfort is evaluated with the General Comfort Questionnaire (GCQ), a self-reported instrument consisting of 48 items that reflect the physical, spiritual, environmental and social dimension. Responses are rated on a four-point Likert scale ranging from "strongly disagree" to "strongly agree". Some items are reverse scored during data processing, with higher overall scores indicating greater levels of comfort.
Secondary outcomes
Quality of life
The McGill Quality of Life Questionnaire (MQOL) will measure quality of life and consists of 17 questions. Higher scores reflect a better quality of life.
Health-related quality of life
The EuroQol with five dimensions and five levels (EQ-5D-5L) will be assessed to measure health-related quality of life. Higher scores reflect a better quality of life.
Pain intensity
The Visual Analogue Scale (VAS - 100 mm) in electronic format will be used for the assessment of current pain intensity.
Pain interference
The NIH-funded Patient-Reported Outcomes Measurement Information System Pain Interference measure assesses the impact of pain on key aspects of an individual's life. It evaluates the extent to which pain disrupts engagement in social, cognitive, emotional, physical, and recreational activities.
