OBJECTIVE
The objective of this study was to estimate the impact of seasonality and immunization on hospitalization rates of elderly people in a southern Brazilian state.
METHODS
An epidemiological study of ecological design, combining time-series in the period 1995-2009, was carried out. The medical records of individuals residing in Santa Catarina aged≥60 years were obtained from the Hospital Information System of the Brazilian National Health System. Multiple linear regression analysis was used to calculate the impact exerted by seasonality and by influenza immunization coverage on hospitalization rates.
RESULTS
A decrease of 5.73% in the rate of hospitalization was observed in the first quarters of the years, and an increase of 8.75% in the third quarters of the years, showing the impact of seasonality. The results also showed that as the vaccination coverage rate increased 1%, a decrease of 0.1% was observed in the hospitalization rate.
CONCLUSION
Seasonality and immunization had an impact on the hospitalization rates of individuals aged≥60 years in the state of Santa Catarina during the period studied.
目的
本研究旨在评估季节性和免疫接种对巴西南部一州老年人住院率的影响。
方法
本研究采用生态学设计的流行病学研究，结合了 1995 年至 2009 年期间的时间序列。从巴西国家卫生系统的医院信息系统中获取了居住在圣卡塔琳娜州≥60 岁的个人的医疗记录。采用多元线性回归分析来计算季节性和流感免疫覆盖率对住院率的影响。
结果
研究发现，每年的第一季度住院率下降了 5.73%，第三季度上升了 8.75%，表明存在季节性影响。结果还表明，随着疫苗接种覆盖率增加 1%，住院率下降了 0.1%。
结论
在研究期间，季节性和免疫接种对圣卡塔琳娜州≥60 岁人群的住院率有影响。
