The 1994 Centers for Disease Control and Prevention draft Guidelines for Preventing the Transmission of Mycobacterium tuberculosis in Health-Care Facilities did not exempt pediatric facilities from instituting controls to prevent nosocomial tuberculosis (TB) transmission. Many researchers contend that TB disease in children does not require such rigid controls. We surveyed acute-care pediatric facilities in the United States to determine adherence to patient and family isolation policies and procedures.
The study included 4 mailings of a survey to infection control professionals at 284 US children's hospitals and adult acute-care hospitals with > 30 pediatric beds.
The overall response rate was 69%. Only 41% of respondents reported having a written TB policy specifically designed for pediatric patients. Whereas 98% of respondents isolated pediatric patients with confirmed pulmonary TB, only 69% reported isolation of patients with miliary TB, and 79% reported isolation of patients with positive gastric aspirates. TB isolation policies for adult visitors were in place at 69% of hospitals, and 50% of hospitals evaluated adults for TB as part of the child's TB treatment plan. A median of 3 contact investigations occurred at each of 47% of respondent hospitals in the preceding 5 years.
Isolation and infection control policies for children with pulmonary TB largely conformed to published guidelines but varied for children with nonpulmonary TB. Because the greatest risk of nosocomial TB transmission in pediatric facilities comes from adults with TB, a rapid TB screening process for parents and adult contacts accompanying affected children should be instituted at facilities caring for children.
1994年美国疾病控制与预防中心起草的《医疗机构预防结核分枝杆菌传播指南》并未豁免儿科机构实施预防医院内结核病(TB)传播的控制措施。许多研究人员认为儿童结核病不需要如此严格的控制措施。我们对美国的急症儿科机构进行了调查,以确定其对患者及家属隔离政策和程序的遵守情况。
该研究向美国284家儿童医院以及拥有超过30张儿科床位的成人急症医院的感染控制专业人员进行了4次问卷调查。
总体回复率为69%。只有41%的受访者报告有专门为儿科患者制定的书面结核病政策。虽然98%的受访者对确诊为肺结核的儿科患者进行了隔离,但只有69%的受访者报告对粟粒性结核病患者进行了隔离,79%的受访者报告对胃液抽吸物呈阳性的患者进行了隔离。69%的医院制定了针对成年访客的结核病隔离政策,50%的医院在儿童结核病治疗计划中对成人进行结核病评估。在过去5年中,47%的受访医院每家平均进行了3次接触者调查。
肺结核患儿的隔离和感染控制政策在很大程度上符合已发布的指南,但非肺结核患儿的政策则有所不同。由于儿科机构中医院内结核病传播的最大风险来自患有结核病的成人,因此在照顾儿童的机构中应建立对受影响儿童的父母和成年接触者进行快速结核病筛查的流程。
