Quality of Life among Chronic Disease Patients

Abstract

Over the last decades considerable attention directed to examine the quality of life (QOL) of chronic patients. Chronic disease patients have impaired performance in physical tasks, lower health-related quality of life and high cardiovascular morbidity and mortality. In an attempt to alleviate their medical or mental condition, several studies have examined which factors affect their quality life, as well as, the bilateral relationship between patients QOL and the symptoms severity level of the disease. Even though previous studies already been conducted in the field of HRQOL of chronic diseases, the knowledge gained in this field is still very limited, with many researches that based on poor quality methodologies. Therefore, the QOL of chronic patients require further inquiry in order to answer diverse questions, such as: whether and how the diseases affect the QOL of the patients? Does improving chronic patients QOL alleviating the symptoms of the disease? And which factors and interventions affect the QOL of chronic patients. In the present study, we have assembled the principal literature in the field of HRQOL and HRQOL in the specific context of chronic diseases. In addition, we have assembled the principal criticism methodological problems and literature gaps that so far did not receive empirical attrition and require the implementation of further research.
