OBJECTIVES: Cost of illness (COI) studies assess the economic impact that diseases place on individuals, healthcare systems, and society. These studies help policymakers understand resource needs and set healthcare priorities. The objective of this study is to systematically review and categorize Türkiye-based COI studies published between 2010 and 2023, analyzing them by disease type and year of publication.
METHODS: A structured search was conducted across six databases: Google Scholar, DergiPark, TR Dizin, PubMed, ISPOR, and YÖKTEZ. Keywords related to cost of illness and Türkiye were used. After removing duplicates and non-relevant entries, abstracts were screened for eligibility based on relevance to disease-specific economic burden. Studies that met the inclusion criteria were transferred to Microsoft Excel for classification and descriptive statistical analysis based on publication year and disease group.
RESULTS: From an initial pool of 1,046 identified records, 316 studies fulfilled eligibility criteria and were included in the final analysis. Publication frequency peaked in 2019 (43 studies, 13.61%), followed by 2022 (36 studies, 11.39%). Cardiovascular diseases emerged as the most frequently studied category (22 studies, 6.96%), closely trailed by renal diseases (21 studies, 6.65%). Other disease groups, including oncology, metabolic disorders, respiratory illnesses, and mental health conditions, appeared with lower prevalence. The steady upward trend in publications signals increased scholarly, clinical, and policy-level interest in the economic evaluation of diseases within Türkiye's healthcare landscape.
CONCLUSIONS: This review highlights the expanding body of cost-of-illness literature in Türkiye, with notable research concentration on cardiovascular and renal diseases. However, substantial gaps persist, underscoring a need for additional research spanning diverse disease categories to better guide evidence-based healthcare planning, policymaking, and optimization of resource allocation within the national healthcare system.
