Trends in treatment of retinal disorders in the Brazilian Public Health System over a 10-year period^*

ABSTRACT

Objective:

To investigate trends in terms of number and cost of intravitreal injection, photocoagulation and panphotocoagulation procedures performed by the Brazilian Public Health System, from 2010 to 2019.

Methods:

The Brazilian Public Health System Database was used as the primary source of data. Intravitreal injection, photocoagulation and panphotocoagulation procedures performed from 2010 to 2019 were investigated. Procedure prevalence and cost trends were analyzed according to year and region. Annual trends were examined using generalized linear models, with a significance level of 5% (p=0.05).

Results:

There was a significant increase in the prevalence of intravitreal injections (1,088%), panphotocoagulation (51%) and photocoagulation (37%) procedures from 2010 to 2019. Intravitreal injections accounted for the most significant increase. However, costs were not significantly readjusted over the years.

Conclusion:

Over a 10-year period, there was a significant increase in the number of procedures associated with retinal disorders. Procedure costs saw little readjustments over time. In spite of limitations, inaccuracies and lack of details, the Brazilian Public Health System Database is the primary source of data for the Public Health System related research in Brazil, and can contribute with information on ocular health and costs of ophthalmic procedures.
