Abstract

Objective

To determine the relative incidence, prevalence, costs, and impact on disability of 8 common conditions treated by rehabilitation professionals.

Data Sources

Comprehensive bibliographic searches using MEDLINE, Google Scholar, and UpToDate, (June, 2013).

Data Extraction

Two review authors independently screened the search results and performed data extraction. Eighty-two articles were identified that had relevant data on the following conditions: Stroke, Spinal Cord Injury, Traumatic Brain Injury, Multiple Sclerosis, Osteoarthritis, Rheumatoid Arthritis, Limb Loss, and Back Pain.

Data Synthesis

Back pain and arthritis (osteoarthritis, rheumatoid arthritis) are the most common and costly conditions we analyzed, affecting more than 100 million individuals and costing greater than $200 billion per year. Traumatic brain injury, while less common than arthritis and back pain, carries enormous per capita direct and indirect costs, mostly because of the young age of those involved and the severe disability that it may cause. Finally, stroke, which is often listed as the most common cause of disability, is likely second to both arthritis and back pain in its impact on functional limitations.

Conclusions

Of the common rehabilitation diagnoses we studied, musculoskeletal conditions such as back pain and arthritis likely have the most impact on the health care system because of their high prevalence and impact on disability.

Methods

The 8 conditions covered in this review were chosen because they commonly require inpatient and outpatient rehabilitation care.7 They include spinal cord injury, traumatic brain injury (TBI), back pain, osteoarthritis, rheumatoid arthritis, multiple sclerosis, stroke, and limb loss.

There are few national guidelines for assessing the economic and social burden of disability. This article is an attempt to organize the differing methods, cost measures, and data sources in the available literature.

Results

After our structured review of the literature, we identified 173 articles of interest, over 85 of which are cited here. Almost all were analyses of national or regional surveys. Pertinent results for all 8 conditions may be found in table 1.

Discussion

Our review of the literature suggests that back pain and arthritis are the most common and costly conditions that we examined, affecting over 100 million individuals and costing more than $200 billion per year. Another condition to note is TBI, which, while less common than arthritis and back pain, carries enormous per capita costs, mostly because of the disability that it may cause. Finally, stroke, which is often listed as the most common cause of disability (unpublished data from National

Conclusions

The limitations noted above highlight the problems in performing this sort of review. In many cases, the data are old, and there is a lack of uniformity in how certain elements, particularly costs and disability burden, are measured. Thus, it is problematic when one wants to compare one time point to the next as well as one disease to another. One solution, although an expensive one, would be to invest more resources in comprehensive national surveys that address the issues raised in this
