RESUMO
Mycobacterium tuberculosis (MTB) is an important problem for human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients. This study investigated whether all cases of MTB reported to the HIV/AIDS Registry (HARS) in Missouri were also reported to the Tuberculosis Information Management System (TIMS) to determine the sensitivity of TIMS and the predictive value of HARS. We found 262 total MTB cases registered in HARS. Of these, 145 (55%) were included in the TIMS. Thirty-eight of the remaining 117 were caused by mycobacteria other than TB leaving 79 for investigation. Chart review of the 79 revealed 16 cases of MTB. Sensitivities and predictive values were calculated first including unknown/unreported group as being MTB-positive and the second including this group as being MTB-negative. Sensitivities for TIMS were 83 and 90%, respectively, and predictive values for HARS were 68 and 63%, respectively. The fact that there were at least 16 unreported cases of MTB has significant public health implications for TB control in Missouri. Public health nursing could work with HARS surveillance staff to help improve the accuracy of case finding and reporting. By whatever means necessary, communications between the TB and HIV programs within the Missouri Department of Health should be enhanced.
