Abstract:

Objective To analyze the implementation status of administrative controls of tuberculosis (TB) infection control in TB outpatient clinics and laboratories at all levels, and to find the principal component index in order to provide references for regulating the implementation of administrative controls in these facilities.Methods On-site observation and inquiry were used to investigate the implementation of administrative controls in TB outpatient clinics and laboratories of 212 TB control facilities. The survey contents included totally 14 items, such as early detection, isolation, health promotion and the using of spittoon with cover, etc. Data were analyzed in descriptive analysis and principal component analysis.Results The rates of implementation of providing health promotion materials in TB outpatient clinics, cough screening for patients and preferentially accepting sputum sample of suspected TB patients in laboratories were higher, which were separately 88.2% (187/212), 85.4% (181/212) and 84.9% (180/212). The rates of implementations of providing separate waiting rooms and spittoons with cover in TB outpatient clinics for patients with cough were lower, which were 54.2% (115/212) and 47.6% (101/212) respectively. Fourteen items of administrative controls were generalized into seven principal components: the comprehensive factor of separating patients and preferentially seeing a doctor in TB outpatient clinics, the factor of early separating patients in TB outpatient clinics, the factor of self-separating of patients, the factor of TB health promotion in out-patient departments, the factor of preferentially accepting sputum sample of suspected patients in laboratories, the factor of placing spittoon with cover in outpatient department and the factor of designating sputum collection area in outpatient department.Conclusion The implementation of administrative controls in different level TB facilities are insufficient. The principal component analysis transforms factors into seven comprehensive factors to reflect the implementation of administrative controls in TB outpatient departments and laboratories of TB facilities, and a comprehensive evaluation model is made according to seven principal factors and their contribution rates.
