Abstract
Chronic diseases in most cases belong to the category of non-communicable diseases (NCDs), which are the main cause of mortality globally. Cardiovascular diseases, diabetes, chronic obstructive pulmonary disease and cancer are the four NCDs responsible for 82% of NCD deaths. Prevention of NCDs implies health promotion activities that encourage healthy lifestyle and limit the initial onset of chronic diseases. Prevention also includes early detection activities, such as screening at-risk populations, as well as strategies for appropriate management of existing diseases and related complications. Early intervention, reducing morbidity and mortality rates could be an appealing idea for patients, physicians and governmental institutions but could also cause harm. Healthcare is undergoing profound changes, and the role of technology in diagnostics and management of chronic diseases in primary healthcare (PHC) is increasing remarkably. However, studies show that the standards of care for chronic diseases and preventive care are met by less than 50%. We still lack clear standards for patients with multiple chronic diseases. The applicability of a single evidence-based guideline to multimorbid patients is limited and can be problematic. Well-designed PHC studies focusing on the impact of medical interventions on morbidity, mortality and quality of life in the fields of early diagnosis, early treatment and multimorbidity are still needed.
