背景：传统的衡量流感病毒影响和成本的方法侧重于肺炎和流感的流行年份和发病率和死亡率。方法：将1989-1990年流感流行季节和1990-1991年非流感流行季节老年医保受益人因肺炎和流感等疾病住院和其他诊断的年化年龄-性别调整后的住院率与1990年没有流感病毒传播的过渡期进行比较。结果：与过渡期相比，各流感时期因肺炎和流感、急性支气管炎、慢性呼吸系统疾病和充血性心力衰竭的住院率显著增加。1989年至1900年的流行季节是发病率最高的时期。1989年至1990年，医疗保险向医院报销的流感活动期过度住院治疗费用超过10亿美元，1990至1991年为近7.5亿美元。结论：衡量美国老年人流感的影响和成本应包括上述所有诊断，并应认识到即使在非流行年份，流感病毒的影响也是显著的。如果实施有效的控制计划，就有很大的机会节省成本。
Background: Traditional methods of measuring the impact and cost of influenza virus have focused on epidemic years and morbidity and mortality due to pneumonia and influenza.Methods: Annualized age-sex-race adjusted rates of hospitalization for pneumonia and influenza and other diagnoses among elderly Medicare beneficiaries during the epidemic influenza season of 1989 to 1990 and the nonepidemic season of 1990 to 1991 were compared with an interim period in 1990 without influenza virus circulation.Results: The rates of hospitalization for pneumonia and influenza, acute bronchitis, chronic respiratory disease, and congestive heart failure were significantly greater during each influenza period compared with the interim period. The highest rates were found in the epidemic season of 1989 to 1900. The amount reimbursed by Medicare to hospitals for the treatment of excess hospitalizations during periods of influenza activity was more than $1 billion in 1989 to 1990 and almost $750 million in 1990 to 1991.Conclusions: Measures of the impact and cost of influenza in elderly Americans should include all of the diagnoses listed above and should recognize that the impact of influenza virus is significant even in nonepidemic years. There are great opportunities for cost savings if effective control programs are implemented.
