The economic burden of osteoporotic fractures may be much higher than estimated: just the tip of the iceberg. In this letter, we suggest that the cost of these fractures might be underestimated by considering only direct medical cost.

We recently read with great interest the article written by Williams et al titled “Economic Burden of Osteoporotic Fractures in US Managed Care Enrollees,” published in the May 2020 issue of The American Journal of Managed Care®.1 Osteoporosis is a major public health problem, and fractures constitute the most important clinical complication of osteoporosis. Williams et al demonstrated the direct medical cost of osteoporotic fractures, which is extremely valuable for drawing attention to aspects of the disease other than medical consequences. As the cited study pointed out a significant economic burden associated with osteoporotic fractures, we would like to augment this conclusion with a comment on other costs of osteoporotic fractures.
Cost-of-illness (COI) studies are important to demonstrate the real burden of diseases and establish health policies. Costs can be classified into 3 categories: direct, indirect, and intangible. Direct cost includes direct medical cost (related to disease treatment) and direct nonmedical cost (such as for transportation, accommodation, and meals).2 Indirect cost refers to the expenses incurred due to loss of productivity, which can be measured and defined as absenteeism and presenteeism. Intangible cost, which cannot be measured quantitatively, includes pain, suffering, and psychiatric problems. Although most of the COI studies so far have mainly focused on direct medical cost, direct nonmedical and indirect costs should not be ignored.2 Although data on the direct nonmedical cost of osteoporotic fractures are scarce, they can be extrapolated from the work of Qu et al, who reported that the direct nonmedical cost was equal to 8% of the direct medical cost of osteoporotic fractures.3 As for the calculation of the indirect cost of osteoporotic fractures, although absenteeism rates may vary depending on the location of the fracture, usually 16% of patients and 8% of family members take time off from work.4 Patients with fractures have 2 more weeks per year of absenteeism than those without fractures. The 1-year cumulative mortality rate after osteoporotic hip fracture varies between 20% and 40%.5 In addition to time off from work, premature deaths are another cause of productivity loss. The indirect cost of fractures due to absenteeism is almost one-third of the total cost of fractures for employed patients in the United States.6 Premature deaths and patients’ and caregivers’ absenteeism result in significant loss of productivity, which leads to a considerable amount of indirect cost.
To sum up, when direct nonmedical and indirect costs are taken into account in addition to direct medical cost, it is evident that the economic burden of osteoporotic fractures on the involved individuals, on the health care system, and on national economies is more significant than previously calculated. The most effective approach to prevent this burden is to change the modifiable risk factors of the patients, develop public programs to prevent osteoporosis, and make interventions to prevent falls.
