RESUMEN
BACKGROUND AND OBJECTIVES: Blood safety and sufficiency are major challenges in Kenya and other sub-Saharan African countries forcing many countries to rely on family replacement donors (FRD). We analysed data from a national AIDS indicator survey to describe blood donors in Kenya and potential risks of transfusion transmissible infections (TTI) comparing voluntary donors and FRD. MATERIALS AND METHODS: A population-based, cross-sectional survey was conducted in 2007 among 15- to 64-year-olds. Consenting participants were interviewed about blood donation history and were tested for HIV, HSV-2 and syphilis. RESULTS: Of the 17,940 people surveyed, 445 (2·3%) reported donating blood in the prior 12 months. Sixty-four per cent were voluntary donors, and the rest were FRD. Compared to FRD, the majority of voluntary donors were <25 years old (59% versus 18%), from the highest wealth quintile (57% versus 42%) and single (64% versus 23%). In addition, voluntary donors were less likely to have been sexually active than replacement donors (43% versus 13%). HIV prevalence was lower among voluntary donors than among FRD (2·6% versus 7·4%, P-value=0·07). CONCLUSIONS: The majority of blood donors in Kenya are voluntary with lower potential risk of TTI.

SETTING: Improved documentation of human immunodeficiency virus (HIV) testing and care among tuberculosis (TB) patients is needed to strengthen TB-HIV programs. In 2007, Kenya piloted the use of personal digital assistants (PDAs) instead of paper registers to collect TB-HIV surveillance data from TB clinics. OBJECTIVE: To evaluate the acceptability, data quality and usefulness of PDAs. DESIGN: We interviewed four of 31 district coordinators who collected data in PDAs for patients initiating TB treatment from April to June 2007. In 10 of 93 clinics, we randomly selected patient records for comparison with corresponding records in paper registers or PDAs. Using Cochran-Mantel-Haenszel tests, we compared missing data proportions in paper registers with PDAs. We evaluated PDA usefulness by analyzing PDA data from all 93 clinics. RESULTS: PDAs were well accepted. Patient records were more frequently missing (28/97 vs. 1/112, P < 0.001) and data fields more frequently incomplete (148/1449 vs. 167/2331, P = 0.03) in PDAs compared with paper registers. PDAs, however, facilitated clinic-level analyses: 48/93 (52%) clinics were not reaching the targets of testing >or=80% of TB patients for HIV, and 8 (9%) clinics were providing <80% of TB-HIV co-infected patients with cotrimoxazole (CTX). CONCLUSION: PDAs had high rates of missing data but helped identify clinics that were undertesting for HIV or underprescribing CTX.
