综合内科65岁以上老年住院患者贫血发生情况

目的：了解住院老年患者贫血的发生率及对预后的影响。方法：回顾分析2000年1月～2006年6月我院高干科和高干保健科≥65岁老年住院患者821例，统计贫血发生率、可能的原因及死亡率。结果：按国内贫血标准，总的贫血发生率为23．87％，其中男性25．19％，女性21．35％；按WHO标准，总的贫血发生率为43．00％，其中男性43．15％，女性42．70％。同一标准内，男女贫血发生率无统计学意义（均P〉0．05）。按国内和WHO标准，65-74岁、75～84岁和〉85岁3个年龄组的贫血发生率均随年龄增长显著增加（P〈0．05，P〈0．01）。按国内及WHO标准，总死亡率贫血组明显高于非贫血组（36．73％和8％，23．51％和8．33％，均P〈0．01）。结论：在综合内科≥65岁老年住院患者中贫血发生率高．贫血比非贫血患者有更高的死亡率，应引起内科医师的高度重视。应积极查找贫血病因．对贫血进行有效的干预。

Prevalence of anemia in hospitalized patients aged 65 years and older in the geriatric department of China-Japan Friendship Hospital

Objective：To investigate the prevalence of anemia and the impact of anemia on the prognosis in hospitalized elderly patients in the geriatric department.Methods：To review 821 cases（male：540,female：281） of the patients aged 65 years and older admitted to the geriatric ward of the hospital from Jan 2000 to Jun 2006,the prevalence of the anemia was counted,and analyzed the potential causes of anemia and the impact of anemia on mortality.Results：According to the national criteria of anemia,the overall prevalence of anemia was 23.87% ,with a prevalence of 25.19% for men and 21.35% for women.However,based on the World Health Organization（WHO） criteria,the overall prevalence of anemia was 43.00%,with a prevalence of 43.15% in men and 42.70% in women.Under the same criteria,there was no statistic difference in prevalence between men and women.According to the national and the WHO criteria,among the three groups of 65-74,75-84 and 〉85 years old,the prevalence of anemia were significantly increased with age （P〈0.05,P〈0.01）.According to the national and the WHO criteria,the overall mortality of the anemia group was significantly higher than the non-anemia group （36.73% and 8%,23.51% and 8.33%,P〈0.01）.Conclusion：There was high prevalence of anemia in hospitalized elderly patients 65 years and older in the geriatric department.The mortality of anemia patients was higher than the non-anemia patients.These should be highly concerned by physicians.The causes of anemia should be actively searched, and the effective intervention for anemia should be taken.
