为了量化成人在流感和呼吸道合胞病毒（RSV）季节的医疗保健使用情况，我们确定了一组年龄大于或等于18岁的退伍军人，他们使用退伍军人事务部（VA）在俄勒冈州和华盛顿州的设施作为他们的医疗保健来源。在1998-2000年期间，退伍军人累积了237 159人年的随访。使用VA数据源，我们测量了急性心肺住院和初级护理和紧急护理访视。流感和/或RSV流行时的研究事件发生率与两种病毒均未流行时的事件发生率之间的差异用于计算冬季病毒归因的发病率。与非冬季病毒季节相比，冬季病毒季节的住院和门诊事件发生率始终较高。流感或RSV感染所致心肺住院的年发生率范围为0.8（95%置信区间[CI]，0.1-1.5）/1000例18-49岁低风险个体至10.6（95% CI，7.5-13.6）/1000例65岁以上高风险个体。每年，流感和RSV的传播与医疗保健使用的可预测增长相吻合。
To quantify health care use among adults during influenza and respiratory syncytial virus (RSV) seasons, we identified a cohort of veterans aged greater than or equal to18 years who used Department of Veterans Affairs (VA) facilities in Oregon and Washington states as their source of health care. During 1998-2000, veterans accrued 237,159 person-years of follow-up. Using VA data sources, we measured acute cardiopulmonary hospitalizations and primary care and urgent care visits. Differences between rates of study events when influenza and/or RSV were circulating and event rates when neither virus was circulating were used to calculate winter virus attributable morbidity. Inpatient and outpatient event rates were consistently higher during winter virus season, compared with non-winter virus season. Annual rates of cardiopulmonary hospitalizations attributable to influenza or RSV infection ranged from 0.8 (95% confidence interval [CI], 0.1-1.5) per 1000 low-risk individuals aged 18-49 years, to 10.6 (95% CI, 7.5-13.6) per 1000 high-risk individuals aged greater than or equal to65 years. Each year, circulation of influenza and RSV coincide with predictable increases in medical care use.
