Eligibility
Inclusion criteria
* Diagnosis of chronic pain (generally pain duration of at least 3-6 months) localized to an anatomical region appropriate for cryoneurolysis as determined by the treating physician. * Planned cryoneurolysis procedure as part of standard clinical care. * Ability to provide written informed consent. * Ability and willingness to complete baseline and follow-up questionnaires.
Exclusion criteria
* Cryoneurolysis performed as part of a separate investigational trial in which data sharing is not permitted. * Active infection or other clinical contraindication to the procedure as determined by the treating clinician. * Life expectancy of less than 12 months in the judgment of the treating clinician. * Any condition that, in the investigator's opinion, would interfere with study participation or completion of follow-up, such as severe psychiatric instability or active substance use that precludes reliable follow-up
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of participants with improvement in pain | 6 and 12 months | Percentage of participants achieving a clinically meaningful improvement in pain. Pain improvement measured as a ≥2-point reduction on the 0-10 Numeric Rating Scale (NRS). NRS is a widely used, validated 0-10, tool for measuring subjective pain intensity, where 0 represents "no pain" and 10 represents "the worst pain imaginable". |
| Change in Pain Disability Index (PDI) score | 6 and 12 months | PDI is a 7-item self-report questionnaire used to measure how chronic pain interferes with various aspects of a person's life, with total scores ranging from 0 (no disability) to 70 (maximum disability). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of pain-related hospital admissions | up to 12 months post cryoneurolysis | Number of pain-related hospital admissions in the 12 months before versus the 12 months after cryoneurolysis. |
| Number of pain-related emergency department visits | up to 12 months post cryoneurolysis | Number of pain-related emergency department visits in the 12 months before versus the 12 months after cryoneurolysis. |
| Number of pain-related medication refills | up to 12 months post cryoneurolysis | Number of pain-related medication refills in the 12 months before versus the 12 months after cryoneurolysis. |
| Number of responders | 6 and 12 month | Responders are participants reporting 'much improved' or 'very much improved' using the Patient Global Impression of Change (PGIC). |
