目的 通过事先检测老年人甲状腺功能，探讨老年患者罹患医院内感染与甲状腺功能减退的关系。方 法 １９９５年检测门诊体检对象之甲状腺功能，项目包括ＴＴ３、ＦＴ３、ＴＴ４、ＦＴ４、及ＴＳＨ，然后前瞻性跟踪调查１９９６年１月～ １９９７年１２月老年病房收治的６０岁以上患者，观察老年人医院内感染与甲状腺功能低下的关系。结果 发现１３４例医 院内感染患者ＴＴ３、ＦＴ３、ＦＴ４及ＴＳＨ显著低于１１４例无医院内感染者，ＴＴ３、ＦＴ３、ＦＴ４及ＴＳＨ不同水平组中有医院内感染者相 对百分率显著高于无医院内感染者。结论 老年人医院内感染与甲状腺功能减退呈显著相关关系，提示常规检测甲 状腺功能对防治老年人医院内感染有重要意义。
Objective To investigate the relationship between nosocomial infection and hypothyroidism in elderly patients by detecting the thyroid function in the elderly in advance. Methods Thyroid function was detected in 1995 outpatients. The items included TT3, FT3, TT4, FT4 and TSH, and then prospectively follow-up investigation of patients over 60 years old from January 1996 to December 1997 in elderly ward, Relationship between hospital infection and hypothyroidism. The results showed that TT3, FT3, FT4 and TSH were significantly lower in 134 patients with nosocomial infection than in 114 patients without nosocomial infection. The relative percentages of patients with nosocomial infections in TT3, FT3, FT4 and TSH groups were significantly higher than those without nosocomial infection Infected. Conclusion There is a significant correlation between nosocomial infection and hypothyroidism in the elderly, suggesting that routine testing of thyroid function is of great importance in the prevention and treatment of nosocomial infections in the elderly.
