Life With Cystic Fibrosis: The Socioeconomic Impact on Patients and Their Caregivers

Objectives

This study aimed to provide the first evidence of the socioeconomic burden of cystic fibrosis (CF) in Czechia.

Methods

In a cross-sectional questionnaire-based primary data collection conducted from 2020 to 2021 among Czech patients with CF, we collected demographic, clinical, and healthcare resource use data, out-of-pocket and social transfer costs, and questionnaires: Cystic Fibrosis Questionnaire-Revised, Work Productivity and Activity Impairment, EQ-5D, and Zarit Burden Interview. Productivity loss/costs were assessed using the human capital approach with patient patient-assumed life expectancy of 45 years and caregiver retirement age of 64 years and discounted by 3%.

Results

A total of 257 patients completed the questionnaires (37% of the Czech CF population). The average age was 17 years; most were females (59%), and the average forced expiratory volume in 1 second was 81.4% (SD 25.4%). A total of 107 patients had caregivers with an average age of 39 years and a significant caregiver time burden (extra 4.6 hours/day). The average Zarit Burden Interview score (25.4) was comparable with advanced cancer, dementia, or Duchenne muscular dystrophy. The proportion of unemployed caregivers was 10× higher than the general population (31% vs 3.2%). Total out-of-pocket family costs related to CF were €278/month, mainly for medicines (€105), foods (€73), and transport (€59); 25% received a disability pension and 18% other social security benefits. The work impairment of employed patients and caregivers was 25% and 15%, respectively, mostly due to presenteeism. Total lifetime productivity costs extrapolated to all Czech patients with CF (n = 687) and their caregivers were €155 181 286 (€225 883/person).

Conclusions

The societal burden imposed on Czech patients with CF and their caregivers is significant. Caregivers seem to be affected by higher disease activity more than patients.
