Rheumatic diseases (RD) are classic causes of pain and physical incapacity, with important socioeconomic repercussions. Osteoarthritis (OA) is a degenerative disease, characterized by loss of joint cartilage and secondary local osteoarthropathy. Age, genetic predisposition, female gender, obesity and heavy mechanical work. It affects around 250 million people worldwide and is the most prevalent RD. Because it is a disease of high prevalence whose main risk factor is age, with the aging of the Brazilian population, it is expected a greater number of patients and higher health expenditures in both the public and private systems. The objective of the present study is to describe and compare hospital morbidity data, as well as costs in Health by OA of Brazilian geographic regions.

Materials and methods

This is a descriptive, ecological study, based on data obtained from the Hospital Information System of the Unified Health System (HIS-UHS). Data on OA (ICD-10 M15-M19 codes) were collected from patients between 20 and 80 years of age in the period 2008-2018. Variables: number of hospitalizations, hospital costs, age group, mean value for hospitalization, age, gender, average hospital stay.

Results

There were 182,067 admissions with an average hospitalization value of R$ 3,540 resulting in a total cost of R$ 644.6 million. This value represents one-fifth of the total amount spent with ICD-10 Osteomuscular and Connective Tissue Diseases and 1% of the cost of hospitalizations for all causes. The mean hospital stay was 9.1 days, with the Northeast region having an average time of 12.1 days. The South, Southeast and Northeast regions accounted for 93.1% of all hospitalizations and more than 90% of total expenditures. Between 2008-2018 there was an average increase of 6.5% in hospitalizations per year and an average increase of 8.5% in hospital costs per year. Patients older than 60 years accounted for 60% of all admissions with a female:male sex of 1,3:1.

Conclusion

The increase in the life expectancy of the Brazilian population has an undeniable impact on the increase of costs mainly by the elderly, and this implies a larger number of hospitalizations in diseases more prevalent in this age group. Given the above epidemiological studies can contribute to improved resource leasing and positively impact on access to health for the population.
