Prevalence and characteristics of chronic pain in survivors of critical illness and impact on daily life and treatment practices.

Abstract

The aim of this study was to evaluate the prevalence and characteristics of Chronic Pain (CP) in survivors of critical illness. The secondary objective was to evaluate the impact of CP on an individual's quality of life and unveiling current pain treatment practices. This study was a cross-sectional survey. Twelve months after intensive care discharge, patients were contacted for an interview. Two questionnaires were administered (Brief Pain Inventory and Euroqol 5D instrument) to assess CP and quality of life. Data was obtained between 20 June and 20 December 2019. 118 patients participated in the study. An overall prevalence rate of 26.3% (n= 31) was found for CP in the study population. The highest prevalence of pain was observed in patients with 40-55 years (41.9%) (n= 13). The prevalence rate in males was 26.3%, similar compared to the rate in females (p=.99). The intensity of pain was similar among females (5.6) and males (5.8) (p=.35). Knees (15.3%), legs (12.7%) and minor joints (12.7%) were the most prevalent sites of pain. The perceived quality of life (EQ VAS) was 74.9 (+9.7) in patients without CP and 58.2 (+9.2) in patients with CP. CP has significant negative consequences for patients. Thus, we want to emphasize the need to adopt a comprehensive and multidisciplinary approach to improving the patient's condition and circumstances, contemplating both pharmacological treatments and non-pharmacological measures.
