Resilience does matter: evidence from a 10-year cohort record linkage study

Area of Science:

• Pain research
• Epidemiology
• Health outcomes research

Background:

• Chronic pain significantly impacts individuals' lives, affecting mortality and hospital use.
• Understanding factors that influence outcomes in chronic pain patients is crucial for effective healthcare strategies.

Purpose of the Study:

• To investigate the 10-year mortality and hospital utilization patterns of individuals categorized as resilient or vulnerable to chronic pain.
• To identify demographic and socioeconomic factors associated with resilience and vulnerability in chronic pain patients.

Main Methods:

• A cohort record linkage study was conducted using data from the Grampian Pain Cohort (n=5858) in Scotland.
• Probability matching linked cohort data with national routinely collected datasets to track mortality and hospital use over 10 years.
• Hazard ratios (HRs) and odds ratios (ORs) were calculated, adjusting for confounding variables like sex, age, housing, employment, and long-term limiting illness.

Main Results:

• Resilient individuals (high pain intensity, low disability) were 25% less likely to die within 10 years (HR 0.75).
• Vulnerable individuals (low pain intensity, high disability) were 45% more likely to die within 10 years (HR 1.45).
• Resilient individuals showed reduced outpatient visits for anesthetics, while vulnerable individuals had fewer overall outpatient visits but more psychiatric visits.

Conclusions:

• Resilience in the context of chronic pain is associated with significantly better 10-year survival.
• Further research is warranted to understand the mechanisms, predictors, and influencing factors of resilience in chronic pain.
