RESUMEN
SETTING: A resource-limited urban setting in Zimbabwe with a high burden of tuberculosis (TB) and human immunodeficiency virus (HIV). OBJECTIVES: To determine the feasibility and yield of diabetes mellitus (DM) screening among TB patients in primary health care facilities. DESIGN: A descriptive study. RESULTS: Of the 1617 TB patients registered at 10 pilot facilities, close to two thirds (60%) were male and 798 (49%) were bacteriologically confirmed. The median age was 37 years; two thirds (67%) were co-infected with HIV. A total of 1305 (89%) were screened for DM, and 111 (8.5%, 95% CI 7.0-10.2) were newly diagnosed with DM. Low TB notifying sites were more likely than high TB notifying sites to screen patients using random blood glucose (RBG) (83% vs. 79%; P < 0.04). Screening increased gradually per quarter over the study period. There were, however, notable losses along the screening cascade, the reasons for which will need to be explored in future studies. CONCLUSION: The study findings indicate the feasibility of DM screening among TB patients, with considerable yield of persons newly diagnosed with DM. Scaling up of this intervention will need to address the observed losses along the screening cascade.
