| 目的探究长期住院老年出院病人实际医院感染率，分析反复感染情况及医院感染的危险因素。方法回顾性分析 2017年 1月 1日至 2020年 12月 31日北京市第二医院办理出院结算的 ≥65岁老年病人医院感染情况，采用非条件 logistic回归方法分析医院感染的危险因素，采用 Spearman秩相关方法进行相关性分析。结果按常规出院结算周期监测报告的 ≥65岁出院病人医院感染率为 3.12%(171/5 480)；合并连续住院病人住院日后， ≥65岁出院病人医院感染率为 28.89%(526/1 821)。多因素非条件 logistic回归分析显示存在侵入性操作［OR=23.05，95%CI:(13.56，39.18)］、住院日 >30 d［OR=27.58，95%CI:(16.20，46.94)］是老年病人医院感染的危险因素。连续住院病人的总住院日与医院感染和耐药菌感染次数均存在正相关关系( P<0.05)。结论长期住院老年病人实际医院感染率高于常规监测报告水平，需提高医院感染诊断准确性。对于存在侵入性操作、住院 >30 d等危险因素的老年病人需提前干预，控制感染发生。 |

| Objective To explore the actual nosocomial infection rate of the elderly patients hospitalized for a long time and analyzethe risk factors for recurrent infection and nosocomial infection.Methods Retrospective cross-sectional study was used to investigatethe nosocomial infection of patients ≥65 years old who were discharged from Beijing Second Hospital from January 1, 2017, to December 31, 2020. Unconditional Logistic regression analysis was used to screen the risk factors. Spearman rank correlation analysis wasused to analyze the correlation between hospital stay and infection factors.Results According to the routine discharge settlement cyclemonitoring, the nosocomial infection rate of discharged patients ≥65 years old was 3.12% (171/5 480). After combined the number ofdays in hospital for consecutive patients,the nosocomial infection rate of discharged patients ≥65 years old was 28.89% (526/1 821).Multivariate unconditional logistic regression analysis showed that invasive operation [OR=23.05, 95%CI:(13.56, 39.18)] and hospital stay > 30 days [OR=27.58, 95%CI:(16.20,46.94)] were risk factors for the nosocomial infection of older patients. There was a positivecorrelation between the total length of stay of consecutive inpatients and the number of cases of nosocomial infection and drug-resistant bacterial infection (P < 0.05).Conclusions The actual nosocomial infection rate of long-term hospitalized older patients is higher thanthat reported by monitoring report, so the accuracy of nosocomial infection diagnosis should be improved. For elderly patients with riskfactors such as invasive operation and hospitalization > 30 days, advance intervention is needed to control infection. |
