Nosocomial infections (NI) are events associated with high impact on hospital costs and mortality.
To evaluate from the health provider's perspective the costs and mortality attributable to NI.
We selected a sample of patients with and without NI matched by age and diagnosis at admission. Costs were calculated and converted from Colombian pesos to US dollars using the average exchange rate of 2008. We evaluated the mortality rate in both groups.
We collected data on 187 patients with NI and 276 without NI. Median total hospitalization cost was US$ 6,329 (95% CI US$5,527-7,934) in NI patients, while in non-infected patients this median was US$1,207 (95% CI US$ 974-1,495). Mortality was higher in the NI group (31.6% versus 5.1%). Patients with NI had longer hospital stays (median 21 days, 95% CI 18-24 days) than non-infected patients (median 5 days, 95% CI 5-6 days). Mortality was also markedly higher in the NI group than in the non-infected group (31.6% versus 5.1%).
NI are adverse and costly events related to patient attention that affect adversely the quality of attention.
医院感染（NI）是对医院成本和死亡率有重大影响的事件。
从医疗服务提供者的角度评估医院感染所致的成本和死亡率。
我们选取了一组年龄和入院诊断相匹配的有医院感染和无医院感染的患者样本。计算成本，并使用2008年的平均汇率将哥伦比亚比索换算为美元。我们评估了两组的死亡率。
我们收集了187例有医院感染患者和276例无医院感染患者的数据。有医院感染患者的住院总费用中位数为6329美元（95%置信区间为5527 - 7934美元），而未感染患者的这一中位数为1207美元（95%置信区间为974 - 1495美元）。医院感染组的死亡率更高（31.6%对5.1%）。有医院感染的患者住院时间更长（中位数21天，95%置信区间为18 - 24天），而未感染患者的住院时间中位数为5天（95%置信区间为5 - 6天）。医院感染组的死亡率也明显高于未感染组（31.6%对5.1%）。
医院感染是与患者护理相关的不良且成本高昂的事件，对护理质量有不利影响。
