Fatigue, quality of life, and use of healthcare resources in children with complex chronic diseases

Abstract

The objective was to assess fatigue in children with complex chronic diseases (CCCDs) and analyze its relationship with clinical and sociodemographic characteristics, use of healthcare services, and quality of life (QoL). Cross-sectional study carried out in CCCDs attended in a tertiary hospital during 2016. Fatigue (PedsFacit-F questionnaire) and quality of life (PedsQL) were determined, and the following variables were registered: use of health resources, disease group, time with disease, and educational level and type of employment of the parents. A multiple regression model was developed to predict the use of healthcare resources. Seventy children were included in this study; mean age 10.5 years (range: 8-17), 41.4% girls, and cancer was the most frequent group disease (28.6%). Annual use of healthcare resources (38.86; SD: 30.73) increased with fatigue (r=-0.292; p=0.015). Higher levels of fatigue were determined for children with cancer (24.9; SD: 10.7) in comparison to other pathologies, while lower levels were found for heart diseases (44.5; SD: 7.9). The QoL perceived by CCCDs (20.6; SD: 16.5) directly correlated (p<0.001) with that of their parents (22.8; SD: 16.8); a correlation with fatigue was seen in both cases (r=0.528 and r= 0.441; p<0.0001). The adjusted effect of higher levels of fatigue (lower scores), lower length of disease duration, and higher level of education of the mother, predicted greater use of healthcare resources. CCCDs with higher fatigue levels use healthcare resources more often and perceive a worse QoL. This should be considered when providing care to this population.
