The Impact of Obesity in Saudi Arabia: Healthcare Resource Use and Costs Associated with Obesity-Related Complications.

Abstract

Saudi Arabia has a high prevalence of obesity, which increases the risk of individuals experiencing multiple chronic complications. Only a few publications highlight the healthcare costs of obesity-related complications (ORCs) in Saudi Arabia. A micro-costing approach was used to estimate the healthcare costs associated with 10 ORCs. Experienced clinicians in public and private practice across different geographical regions in Saudi Arabia were asked to estimate healthcare resource use associated with each ORC, and estimated unit costs were obtained from hospital administrators. Estimated overall annual costs per patient were calculated as a weighted average of separate public and private sector costs. Individuals in Saudi Arabia with any single ORC incurred overall average annual healthcare costs of 2165-7558 US dollars (USD). Heart failure, chronic kidney disease, dyslipidemia, and type2 diabetes (T2D) were the most costly complications, mainly driven by monitoring and/or pharmacological treatment costs. In contrast, asthma, hypertension, and angina were the least costly complications. Costs in private healthcare were higher than in public healthcare; the largest differences (2359-2793USD) were noted for dyslipidemia, T2D, and osteoarthritis, mainly explained by differences in pharmacological treatment costs. These data suggest that ORCs result in a considerable financial burden to the healthcare system, and highlight the substantial cost savings that could be achieved by preventing or delaying the occurrence of ORCs in Saudi Arabia.
