305例老年死亡病例医院感染回顾性调查

A Retrospective Study of Hospital Infections in 305 Cases of Elderly Death

本文结果表明,305例老年死亡病例医院感染的发病率为33.8％。感染最多部位为肺部(66.9％),其次为尿路感染(19.4％)。高龄患者,侵袭性操作、多种抗生素联合应用,激素疗法等是诱发医院感染的危险因素。58.8％的病原菌为革兰氏阴性杆菌,37.2％为真菌。31株病原菌药敏结果显示耐药率为33.3％。本文指出合理应用抗生素是预防医院感染的重要措施之一。

The result of the study shows that the morbidity of the hospital infection in 305 elderly died cases dis- eases was 33.8%, The lungs were the first major site of the infection (66.9%) and followed by urinary tract infection (19.4%), The factors of high risk in- ducing hospital infection included advanced age invasive procedures, multi-antibiotics used in com- bination and hormonotherapy. Of the pathogenic bacteria causing the hospital infection gram-nega- tive bacilli were accounted for 58.8% and fungus 37.2%. The results of antibiotic drug-sensitivity tests of 31 strains showed that the rate of resistance was 33.3%. The present paper indicated that the fa- tional application of antibiotics is one of the most important measures to prevent hospital infections.
