OBJECTIVES: Atopic dermatitis (AD) is a chronic inflammatory disease affecting approximately 2.7% of individuals in Brazil. Elderly patients, particularly those unresponsive to conventional treatments, may have higher health risks and associated healthcare costs. This study aimed to analyze risk of hospitalizations due to AD among elderly patients in the Brazilian public health system.
METHODS: The Brazilian population in 2023 was estimated using projections from the Brazilian Institute of Geography and Statistics. We considered the prevalence of AD in Brazil according to the Global Burden of Disease (2021). Hospitalization data for 2023 were obtained from the Brazilian public health database (DATASUS), using the national procedure code for dermatitis and eczema treatment and specific ICD-10 codes for AD. Variables analyzed included the number and duration of hospitalizations and costs, stratified by age (adults [≥ 18 to < 60 years old] vs. elderly [≥ 60 years old]) and sex. Relative risk of hospitalization was estimated according to age. Data analysis was conducted on R.
RESULTS: We estimated 1.5 million adults and 438 thousand elderly individuals with AD. A total of 675 hospitalizations were identified, with 264 involving elderly patients, accounting for 39.1% of all hospitalizations among individuals over 18 years old. The days of hospitalization[CBM2] and median of hospitalization cost were higher in elderly group compared to adult group (p<0.05 and p<0.001, respectively). The risk of hospitalization was 2.27 (CI 95% 1.94 to 2.65) fold higher in elderly group compared to adults. The risk of hospitalization was 1.89 (CI 95% 1.50 to 2.38) and 2.76 (CI 95% 2.25 to 3.40) fold higher in elderly compared to adults in woman and men, respectively.
CONCLUSIONS: The study highlights a higher risk of hospitalizations in elderly patients due to AD compared to adults, consistent in men and women.
