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

objectivesTo examine 10-year mortality and hospital use among individuals categorised as resilient and vulnerable to the impact of chronic pain.

designA cohort record linkage study.

settingGrampian, Scotland.

participants5858 individuals from the Grampian Pain Cohort, established in 1996, were linked, by probability matching, with national routinely collected datasets.

main outcome measuresHRs for subsequent 10-year mortality and ORs/incidence rate ratios for subsequent 10-year hospital use, each with adjustment for potential confounding variables.

results36.5% of those with high pain intensity reported a low pain-related disability (categorised resilient) and 7.1% of those reporting low pain intensity reported a high pain-related disability (categorised vulnerable). Sex, age, housing, employment and long-term limiting illness were independently associated with being vulnerable or resilient. After adjustment for these variables, individuals in the resilient group were 25% less likely to die within 10 years of the survey compared with non-resilient individuals: HR 0.75, 95% CI 0.62 to 0.91 and vulnerable individuals were 45% more likely to die than non-vulnerable individuals: HR 1.45, 95% CI 1.01 to 2.11. Resilient individuals were less likely to have had an outpatient or day-case visit for anaesthetics: OR 0.46, 95% CI 0.27 to 0.79, but no other clinical specialities. Vulnerable individuals were significantly less likely to have had any outpatient or day-case visit (OR 0.43, 0.25 to 0.75); but more likely to have had a psychiatric visit (OR 1.96, 1.06 to 3.61). No significant differences in likelihood of any inpatient visits were found.

conclusionsResilient individuals have a better 10-year survival than non-resilient individuals indicating that resilience is a phenomenon worth researching. Further research is needed to explore who is likely to become resilient, why and how, as well as to tease out the internal and external factors that influence resilience.
